Description

Technical Field

[0001] This application belongs to the field of clamp fastening technology, and in particular relates to a clamp fastening device. Background Technology

[0002] Nuclear power plants are internally divided into multiple functional areas (such as inside the containment, outside the containment, and auxiliary buildings), each with different requirements for safety and sealing. Electrical penetrations (e.g., medium-voltage electrical penetrations) must transfer power from one area to another to supply equipment (such as pumps, fans, and control systems) without compromising the area isolation. Electrical penetrations consist of an outer shell and a conductive rod. The outer shell is embedded within the partition structure between different functional areas (e.g., concrete walls or metal partitions). The conductive rod electrically connects the two functional areas. After passing through the outer shell from one functional area, the conductive rod is electrically connected to electrical components (e.g., cables, conductive plates, electrical connecting rods) in other areas via clamps. The clamps are primarily tightened manually using wrenches or other tightening tools. Manual installation can easily result in the clamps not fitting tightly to the conductive rods, which is detrimental to improving the quality of clamp maintenance and tightening.

[0003] The above statements are for the purpose of providing background information in relation to this application only and do not necessarily constitute prior art. Summary of the Invention

[0004] The purpose of this application is to provide a clamp fastening device and a clamp fastening method, including but not limited to solving the problem that manual installation in related technologies often results in the clamp not being tightly fitted to the conductive rod.

[0005] The technical solution adopted in the embodiments of this application is:

[0006] In a first aspect, a clamp fastening device is provided, comprising a tightening device, a main body, a cover assembly, and a ranging assembly. The cover assembly includes a cover, a first elastic element, a second elastic element, a first floating sleeve, and a second floating sleeve. The cover has a first receiving cavity for accommodating at least a portion of a first semicircular plate of the clamp. The first and second floating sleeves are mounted on opposite sides of the first receiving cavity, and the first and second floating sleeves cannot rotate relative to the cover about their own axes. The first elastic element is located between the first floating sleeve and the bottom wall of the first receiving cavity to push the first floating sleeve to float along its own axis. The second elastic element is located between the second floating sleeve and the bottom wall of the first receiving cavity to push the second floating sleeve to float along its own axis. The cover has a measuring surface perpendicular to the axis of the first floating sleeve. The main body includes a mounting base, a power component, a first rotating sleeve, and a second rotating sleeve. The power component is connected to the mounting base, and the first rotating sleeve... The first and second rotating sleeves are rotatably connected to the mounting base. A power unit is connected to the first and second rotating sleeves and drives them to rotate about their own axes. The mounting base has a second receiving cavity for accommodating at least a portion of the second semicircular plate of the clamp. The first and second rotating sleeves are located on opposite sides of the second receiving cavity. The cover and the mounting base are movably connected. In the first floating sleeve and the first rotating sleeve, one is used for a nut fitted onto one side of a bolt on the clamp, and the other is used for a nut fitted onto that bolt. In the second floating sleeve and the second rotating sleeve, one is used for a nut fitted onto the other side of a bolt on the clamp, and the other is used for a nut fitted onto that bolt. The ranging assembly includes a first ranging element and a second ranging element connected to the mounting base and arranged side-by-side. The first and second ranging elements are positioned opposite the measuring surface and are used to measure the distance between the measuring surface and the mounting base.

[0007] Secondly, a clamp fastening method is provided, employing the aforementioned clamp fastening equipment. The clamp fastening method includes:

[0008] Place the first floating sleeve and the second floating sleeve onto the nuts of the bolts on both sides of the clamp, and place the first rotating sleeve and the second rotating sleeve onto the nuts of the bolts on both sides of the clamp; then connect the cover and the mounting base.

[0009] The power unit is activated, which drives the first and second rotating sleeves to tighten the nuts on both sides of the clamp. After the nuts on both sides of the clamp are tightened to a preset state, the first and second measuring elements measure the distance between the measuring surface and the mounting base to obtain a first distance value and a second distance value. Based on whether the difference between the first and second distance values ​​meets a preset condition, the parallelism of the first and second semicircular plates of the clamp is determined.

[0010] The clamp fastening device provided in this application has one of the following technical effects: During the clamp fastening process, the first and second elastic elements abut against the two connecting parts of the first semicircular plate, allowing the tightening status of the screws on both sides of the clamp to be reflected by the inclination of the measuring surface. The distance between the measuring surface and the mounting base is then quantified by measuring the distance using the first and second measuring elements to determine the inclination of the measuring surface and obtain the fit between the conductive rod and the clamp. If the fit between the conductive rod and the clamp is not satisfactory, it can be adjusted in time, which helps improve the maintenance and fastening quality of the clamp. Furthermore, the clamp is tightened by using a power component to drive the first and second rotating sleeves to rotate, which is more efficient than manual tightening, thus improving maintenance quality.

[0011] The above description is only an overview of the technical solution of this application. In order to better understand the technical means of this application and to implement it in accordance with the contents of the specification, and to make the above and other objects, features and advantages of this application more obvious and understandable, the following are specific embodiments of this application.

Detailed Implementation

[0025] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0026] In the description of the embodiments of this application, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined with "first" and "second" may explicitly or implicitly include at least one of that feature.

[0027] In the description of this application, "multiple" means at least two, such as two, three, etc., unless otherwise expressly and specifically limited.

[0028] In this application, unless otherwise expressly specified and limited, the terms "installation," "connection," "linking," "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise expressly limited. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0029] In this application, unless otherwise expressly specified and limited, "above" or "below" the second feature can mean that the first feature is in direct contact with the second feature, or that the first feature is in indirect contact with the second feature through an intermediate medium. Furthermore, "above," "on top of," and "over" the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.

[0030] In the description of this application, it should be understood that the terms "inner", "outer", "side", "upper", "bottom", "front", "rear", etc., indicating the orientation or positional relationship are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

[0031] In the description of this application, it should be noted that the term "and / or" is merely a description of the relationship between related objects, indicating that there can be three relationships. For example, A and / or B can represent three situations: A exists alone, A and B exist simultaneously, and B exists alone.

[0032] It should also be noted that in the embodiments of this application, the same reference numerals are used to represent the same component or part. For the same part in the embodiments of this application, the reference numerals may only be used to mark one part or component as an example. It should be understood that the reference numerals are also applicable to other identical parts or components.

[0033] A nuclear power plant is internally divided into multiple functional areas (such as inside the containment, outside the containment, and auxiliary buildings), each with different requirements for safety and sealing. Electrical penetrations must transfer power from one area to another to supply equipment (such as pumps, fans, and control systems) without compromising the isolation between these areas. Electrical penetrations consist of an outer shell and a conductive rod. The outer shell is embedded within the partition structure between different functional areas (e.g., concrete walls or metal partitions). The conductive rod electrically connects the two functional areas. After penetrating from one functional area into the outer shell, the conductive rod is electrically connected to electrical components (e.g., cables, conductive plates, electrical connecting rods) in other areas via clamps.

[0034] See Figure 2 As shown, the clamp 200 includes a first semicircular plate 210 and a second semicircular plate 220. The first semicircular plate 210 includes a first semicircular portion 211 and two first connecting portions 212, which are respectively connected to the opposite sides of the first semicircular portion 211. The second semicircular plate 220 includes a second semicircular portion 221 and two second connecting portions 222, which are respectively connected to the opposite sides of the second semicircular portion 221. The first semicircular plate 210 and the second semicircular plate 220 are joined together. The first semicircular portion 211 and the second semicircular portion 221 form a circular hole. The conductive rod 400 passes through the semicircular hole. The two first connecting portions 212 are respectively fixedly connected to the two second connecting portions 222 by bolts 300. The first connecting portion 212 or the second connecting portion 222 is electrically connected to electrical components in other areas, thus realizing the transmission of electrical energy.

[0035] However, the bolts of the clamp are tightened by hand using wrenches and other tightening tools. Tightening the bolts by hand can easily result in inconsistent tightening. The distance between the first and second connecting parts on one side is different from that on the other side. This causes the surfaces of the first and second connecting parts on both sides to be non-parallel, making it impossible for the conductive rod to fit tightly with the first or second semicircle. This is not conducive to improving the quality of maintenance and power transmission.

[0036] Based on this, the present application provides a clamp fastening device that can tighten the clamp and determine whether the surfaces of the first and second semicircular plates are parallel by measuring with the first and second measuring elements, thereby ensuring that the first and second semicircular plates are tightly fitted with the conductive rod, improving maintenance quality and power transmission quality.

[0037] The following combination Figures 1-10 The clamp fastening device according to the embodiments of this application will be described.

[0038] like Figures 1-4As shown, in some embodiments, the clamp fastening device includes a tightening device 10, which includes a cover assembly 12, a main body 11, and a ranging assembly 13. The cover assembly 12 includes a cover 121, a first elastic element 128, a second elastic element 129, a first floating sleeve 130, and a second floating sleeve 131. The cover 121 has a first receiving cavity 1211 for accommodating at least a portion of a first semicircular plate 210 of the clamp 200. The first floating sleeve 130 and the second floating sleeve 131 are mounted on opposite sides of the first receiving cavity 1211, and the first floating sleeve 130 and the second floating sleeve 131 cannot rotate relative to the cover 121 about their own axis. The elastic element 128 is located between the first floating sleeve 130 and the bottom wall of the first receiving cavity 1211 to push the first floating sleeve 130 to float along its own axial direction. The second elastic element 129 is located between the second floating sleeve 131 and the bottom wall of the first receiving cavity 1211 to push the second floating sleeve 131 to float along its own axial direction. The cover 121 has a measuring surface 1212, which is perpendicular to the axial direction of the first floating sleeve 130. The main body 11 includes a mounting base 111, a power component 112, a first rotating sleeve 113, and a second rotating sleeve 114. The power component 112 is connected to the mounting base 111, and the first rotating sleeve 113 and the second rotating sleeve 114 are connected to each other. 14 is rotatably connected to the mounting base 111. A power component 112 is connected to the first rotating sleeve 113 and the second rotating sleeve 114, and is used to drive the first rotating sleeve 113 and the second rotating sleeve 114 to rotate about their own axes. The mounting base 111 has a second receiving cavity 11111 for accommodating at least a portion of the second semicircular plate 220 of the clamp 200. The first rotating sleeve 113 and the second rotating sleeve 114 are located on opposite sides of the second receiving cavity 11111. The cover 121 and the mounting base 111 are movably connected. One of the first floating sleeve 130 and the first rotating sleeve 113 is fitted onto one side of the clamp 200 by a bolt 300. The first is a nut 310, and the second is a nut 320 for fitting onto the bolt 300; in the second floating sleeve 131 and the second rotating sleeve 114, one is a nut 310 for fitting onto the other side of the clamp 200 of a bolt 300, and the other is a nut 320 for fitting onto the bolt 300; the ranging assembly 13 includes a first ranging element 1301 and a second ranging element 1302 connected to the mounting base 111 and arranged side by side. The first ranging element 1301 and the second ranging element 1302 are arranged opposite to the measuring surface 1212. The first ranging element 1301 and the second ranging element 1302 are used to measure the distance between the measuring surface 1212 and the mounting base 111.

[0039] The cover assembly 12 is a component for accommodating the first semi-circular plate 210. The cover assembly 12 includes a cover 121, a first elastic element 128, a second elastic element 129, a first floating sleeve 130, and a second connecting sleeve 11223. The inner cavity formed by the cover 121 is the first receiving cavity 1211. An opening is formed on one side of the first receiving cavity 1211, and the side wall of the cover 121 opposite to the opening is the bottom wall of the first receiving cavity 1211.

[0040] The first receiving cavity 1211 is used to receive the first semi-circular plate 210. The side wall of the first receiving cavity 1211 can also abut against the side of the first semi-circular plate 210 to limit the first semi-circular plate 210, thereby facilitating the first floating sleeve 130 and the second floating sleeve 131 to be sleeved on the bolt 300 of the clamp 200.

[0041] In some examples, the first semicircular plate 210 may be partially located within the first receiving cavity 1211.

[0042] For example, the portion of the first semicircular portion 211 and the two first connecting portions 212 of the first semicircular plate 210 that connect to the second semicircular plate 220 is located in the first receiving cavity 1211, while the portion of the first connecting portion 212 that connects to other electrical components is located outside the first receiving cavity 1211.

[0043] In some examples, the first semicircular plate 210 may also be entirely located within the first receiving cavity 1211.

[0044] The first floating sleeve 130 and the second floating sleeve 131 can refer to sleeves used to fit onto the nut 310 or nut 320 of the screw. The sleeve has a fitting hole that matches the shape of the nut 310 or nut 320. The fitting hole can be a polygonal hole or a ratchet hole. The sleeve is fitted onto the nut 320 or nut 310. The sleeve is relatively fixed to the nut 320 or nut 310. The sleeve cannot rotate relative to the nut 320 or nut 310 around its own axis, so as to fix the nut 320 or nut 310.

[0045] The first floating sleeve 130 and the second floating sleeve 131 are installed on opposite sides of the first receiving cavity 1211. After the first semicircular plate 210 is placed into the first receiving cavity 1211, the first floating sleeve 130 and the second floating sleeve 131 can be fitted onto the bolts 300 of the two first connecting parts 212 of the first semicircular plate 210. The first floating sleeve 130 and the second floating sleeve 131 are movably installed on the cover 121, and the first floating sleeve 130 and the second floating sleeve 131 cannot rotate relative to the cover 121 around their own axis. The nuts 310 or nuts 320 of the bolts 300 can be fixed to facilitate subsequent tightening of the bolts 300.

[0046] The first elastic element 128 and the second elastic element 129 can be, but are not limited to, springs, sheet metal, or other structures. The first elastic element 128 is disposed between the first floating sleeve 130 and the bottom wall of the first receiving cavity 1211, so that the first floating sleeve 130 can abut against the cavity wall surface of the first receiving cavity 1211 along its own axial direction. In addition, under the elastic force of the first elastic element 128, the first elastic element 128 can push the first floating sleeve 130 to abut against the corresponding first connecting part 212. Under the elastic force of the second elastic element 129, the second elastic element 129 can push the second floating sleeve 131 to abut against the corresponding first connecting part 212.

[0047] The measuring surface 1212 can refer to a surface of the cover 121, which is used to cooperate with the first measuring element 1301 and the second measuring element 1302 to measure the distance between the measuring surface 1212 and the mounting base 111. The measuring surface 1212 can be the surface of the cover 121 that protrudes outside the tightening device 10, or it can be the surface of the cover 121 facing the mounting base 111.

[0048] The main body 11 can refer to the main part of the tightening device 10. The main body 11 includes a mounting base 111, a power component 112, a first rotating sleeve 113, and a second rotating sleeve 114. The mounting base 111 forms a second receiving cavity 11111, and an opening is formed on one side of the second receiving cavity 11111. The side wall of the mounting base 111 opposite to the opening is the bottom wall of the second receiving cavity 11111.

[0049] The second receiving cavity 11111 is used to receive the second semicircular plate 220. The side wall of the second receiving cavity 11111 can also abut against the side of the second semicircular plate 220 to limit the position of the second semicircular plate 220, thereby facilitating the first rotating sleeve 113 and the second rotating sleeve 114 to be sleeved on the bolt 300 of the clamp 200.

[0050] In some examples, the second semicircular plate 220 may be partially located within the second receiving cavity 11111.

[0051] In some examples, the second semicircular plate 220 may also be entirely located within the second receiving cavity 11111.

[0052] The first rotating sleeve 113 and the second rotating sleeve 114 can refer to sleeves used to fit onto the nut 310 or nut 320 of the screw. The sleeve has a fitting hole that matches the shape of the nut 310 or nut 320. The fitting hole can be a polygonal hole or a ratchet hole. The sleeve is fitted onto the nut 320 or nut 310. The sleeve is fixed relative to the nut 320 or nut 310. The sleeve cannot rotate relative to the nut 320 or nut 310 around its own axis so as to facilitate the rotation of the nut 320 or nut 310.

[0053] The first rotating sleeve 113 and the second rotating sleeve 114 are installed on opposite sides of the second receiving cavity 11111. After the second semicircular plate 220 is placed into the second receiving cavity 11111, the first rotating sleeve 113 and the second rotating sleeve 114 can be sleeved on the bolts 300 of the two second connecting parts 222 of the second semicircular plate 220. The first rotating sleeve 113 and the second rotating sleeve 114 are rotatably installed on the mounting base 111. The first rotating sleeve 113 and the second rotating sleeve 114 can rotate relative to the mounting base 111 around their own axis, which can drive the nut 310 or the nut 320 of the bolt 300 connected thereto to rotate, thereby tightening the bolt 300.

[0054] The first semicircular plate 210 is placed in the first receiving cavity 1211 of the cover 121, and the second semicircular plate 220 is placed in the second receiving cavity 11111 of the mounting base 111. The cover 121 and the mounting base 111 are connected. The first floating sleeve 130 and the first rotating sleeve 113 are respectively sleeved on the nut 320 and the screw cap 310 of the same bolt 300 located on one side of the clamp 200. The second floating sleeve 131 and the second rotating sleeve 114 are respectively sleeved on the nut 320 and the screw cap 310 of the same bolt 300 located on the other side of the clamp 200.

[0055] For example, the first floating sleeve 130 and the second floating sleeve 131 are sleeved on the nuts 310 of the bolts 300 located on both sides, and the first rotating sleeve 113 and the second rotating sleeve 114 are sleeved on the nuts 320 of the bolts 300 located on both sides. The first floating sleeve 130 and the second floating sleeve 131 restrict the rotation of the nuts 310 of the corresponding bolts 300. The first rotating sleeve 113 and the second rotating sleeve 114 rotate under the drive of the power component 112, thereby driving the corresponding nuts 320 to rotate, thereby realizing the tightening of the bolts 300, that is, the tightening of the clamp 200.

[0056] The number of the first floating sleeve 130, the second floating sleeve 131, the first rotating sleeve 113, and the second rotating sleeve 114 can be one or more, and their specific number can be designed according to the number of bolts 300 of the clamp 200.

[0057] For example, there are two types of first floating sleeve 130, second floating sleeve 131, first rotating sleeve 113 and second rotating sleeve 114.

[0058] The cover 121 and the mounting base 111 are movably connected. It is understood that the cover 121 and the mounting base 111 can move relative to each other, and the range of movement can be selected according to the actual situation, which is not limited here.

[0059] The power component 112 can refer to a component that can output rotational power. The power component 112 is used to drive the first rotating sleeve 113 and the second rotating sleeve 114 to rotate. The power component 112 can be a motor or the like.

[0060] The ranging component 13 is a component used to measure the distance between the mounting base 111 and the measuring surface 1212. The ranging component 13 includes a first ranging element 1301 and a second ranging element 1302, which are arranged side by side. The first ranging element 1301 and the second ranging element 1302 can measure the distance between different positions of the measuring surface 1212 and the mounting base 111. The first ranging element 1301 and the second ranging element 1302 can be components such as a ranging sensor.

[0061] In some examples, when the clamp fastening device tightens the clamp 200, the first semicircular plate 210 and the second semicircular plate 220 are initially clamped onto the conductive rod 400. The first semicircular plate 210 is placed in the first receiving cavity 1211 of the cover 121, which is connected to the mounting base 111. The first floating sleeve 130 and the second floating sleeve 131 are respectively fitted onto the nuts 310 of the bolts 300 on both sides of the clamp 200. The second semicircular plate 220 is placed in the second receiving cavity 11111 of the mounting base 111. Inside, the first rotating sleeve 113 is fitted onto the nut 320 of the bolt 300 connected to the first floating sleeve 130, and the second rotating sleeve 114 is fitted onto the nut 320 of the bolt 300 connected to the second floating sleeve 131. The first floating sleeve 130 and the second floating sleeve 131 cannot rotate relative to the cover 121 around their own axis, thereby fixing the nut 310 of the bolt 300. The power unit 112 drives the first rotating sleeve 113 and the second rotating sleeve 114 to rotate around their own axis. This causes the nuts 320 on both sides of the clamp 200 to rotate, thereby tightening the bolts 300 of the clamp 200. After the bolts 300 are tightened, under the elastic force of the first elastic element 128 and the second elastic element 129, the first floating sleeve 130 and the second floating sleeve 131 respectively abut against the two first connecting parts 212 of the first semicircular plate 210. If the tightening degree of the bolts 300 on the two first connecting parts 212 is inconsistent, the first elastic element 128 and the second elastic element 129 push the cover. If the body 121 is tilted, the measuring surface 1212 will also be tilted, resulting in the distance values ​​between the measuring surface 1212 and the mounting base 111 measured by the first measuring element 1301 and the second measuring element 1302 being inconsistent or having an excessively large difference. This indicates that the clamp 200 and the conductive rod 400 are not tightly fitted. If the distance values ​​measured by the first measuring element 1301 and the second measuring element 1302 are consistent, it can be determined that the clamp 200 is properly tightened and the conductive rod 400 and the clamp 200 are tightly fitted.

[0062] However, in machining and assembly, due to limitations in the measurement errors of the first measuring element 1301 and the second measuring element 1302, the fitting clearance between the sleeve and the bolt 300, and other factors related to the machining accuracy of the parts, as well as environmental factors such as vibration and temperature deformation, the fact that the distance values ​​measured by the first measuring element 1301 and the second measuring element 1302 are consistent, i.e., the difference between the two is 0, is a theoretical ideal state, which is difficult to achieve in actual operation. Therefore, the error can be defined within an acceptable range according to the actual situation, and the difference between the distance values ​​measured by the first measuring element 1301 and the second measuring element 1302 can be set within a preset condition. For example, the difference between the distance values ​​measured by the first measuring element 1301 and the second measuring element 1302 can be less than or equal to a preset threshold. The preset threshold can be, but is not limited to, 0.1mm, 0.2mm, 0.3mm, etc. As long as the difference does not exceed the preset threshold, it can be considered that the parallelism of the first semicircular plate 210 and the second semicircular plate 220 meets the fitting requirements of the conductive rod 400, reducing the risk of over-adjustment or judgment failure caused by pursuing an absolutely ideal state.

[0063] Of course, in other examples, the first floating sleeve 130 is fitted onto the nut 320 of the bolt 300, the first rotating sleeve 113 is fitted onto the nut 310 of the bolt 300, the second floating sleeve 131 is fitted onto the nut 320 of the bolt 300, and the second rotating sleeve 114 is fitted onto the nut 310 of the bolt 300.

[0064] In the clamp fastening device of this application embodiment, during the clamp 200 fastening process, the first elastic element 128 and the second elastic element 129 abut against the two connecting parts of the first semi-circular plate 210, so that the tightening status of the screws on both sides of the clamp 200 can be reflected by the inclination of the measuring surface 1212. Then, the distance between the measuring surface 1212 and the mounting base 111 is measured by the first measuring element 1301 and the second measuring element 1302 for quantification, and the inclination status of the measuring surface 1212 is judged to obtain the fit between the conductive rod 400 and the clamp 200. If it is found that the fit between the conductive rod 400 and the clamp 200 is not satisfactory, it can be adjusted in time, which is beneficial to improving the maintenance quality and fastening quality of the clamp 200. In addition, the clamp 200 is tightened by using the power component 112 to drive the first rotating sleeve 113 and the second rotating sleeve 114 to rotate. Compared with manual tightening, the clamp 200 has a high tightening efficiency, which is beneficial to improving the maintenance quality.

[0065] In some embodiments, at least one of the first rangefinder 1301 and the second rangefinder 1302 is a laser rangefinder sensor.

[0066] By adopting the technical solution of this embodiment, the laser rangefinder sensor has high measurement accuracy, which helps to improve the accuracy of measurement results, the accuracy of clamp tightness judgment, and the tightness quality of clamp 200. Using a laser rangefinder sensor for non-contact measurement enables real-time acquisition of clamp 200 parallelism data during clamping, solving the problem of untimely measurement caused by clamp 200 movement.

[0067] In some embodiments, a measuring plate 1213 is provided on the outer side of the cover 121, and a mounting portion 1113 is provided on the outer side of the mounting base 111. A first measuring element 1301 and a second measuring element 1302 are connected to the mounting portion 1113. The measuring plate 1213 and the mounting portion 1113 are located on the same side of the tightening device 10, and a measuring surface 1212 is formed on the surface of the measuring plate 1213 facing the mounting portion 1113.

[0068] A measuring plate 1213 protrudes from one side of the cover 121. The mounting base 111 is provided with a mounting part 1113 on the same side as the cover 121. The mounting part 1113 is used as the mounting base 111 for the first measuring element 1301 and the second measuring element 1302. The mounting part 1113 can refer to the shell structure covering the first measuring element 1301 and the second measuring element 1302. The mounting part 1113 and the mounting base 111 can be connected by screws, adhesive or snap-fit.

[0069] The gap between the first semicircular plate 210 and the second semicircular plate 220 of the clamp 200 is small, and conventional ranging probes are not easy to enter the gap. However, by using the measuring plate 1213, the gap difference can be measured on the outside of the clamp 200, thereby measuring the parallelism of the clamp 200, reducing the difficulty of gap measurement. Furthermore, by using a laser ranging sensor to measure the real-time gap data of the clamp 200, the plane of the clamp 200 is transformed into a measurable reference surface, realizing non-contact real-time detection of the parallelism of the clamp 200.

[0070] By adopting the technical solution of this embodiment, the measuring plate 1213 and the mounting part 1113 are located on the same side of the tightening device 10, which facilitates the measurement of the first measuring element 1301 and the second measuring element 1302. In addition, the measuring plate 1213 and the mounting part 1113 are located on the outside of the tightening device 10, which reduces the risk of the components of the tightening device 10 obstructing the first measuring element 1301 and the second measuring element 1302, and helps to improve the accuracy of the measurement.

[0071] Please refer to the following: Figure 5 and Figure 6As shown, in some embodiments, the cover 121 further includes a first mounting cylinder 122, a first limiting member 123, and a first connecting shaft 124. The first mounting cylinder 122 is fixedly connected to the bottom wall of the first receiving cavity 1211. One end of the first connecting shaft 124 is inserted into the first mounting cylinder 122. The first limiting member 123 connects the first connecting shaft 124 and the first mounting cylinder 122 to restrict the relative rotation of the first connecting shaft 124 and the first mounting cylinder 122. The other end of the first connecting shaft 124 is connected to the first floating sleeve 130. A first elastic member 128 is disposed between the first connecting shaft 124 and the first mounting cylinder 122. Between the bottom walls of the cylinder; the cover 121 also includes a second mounting cylinder 125, a second limiting member 126 and a second connecting shaft 127. The second mounting cylinder 125 is fixedly connected to the bottom wall of the first receiving cavity 1211. One end of the second connecting shaft 127 is inserted into the second mounting cylinder 125. The second limiting member 126 connects the second connecting shaft 127 and the second mounting cylinder 125 to limit the relative rotation of the second connecting shaft 127 and the second mounting cylinder 125. The other end of the second connecting shaft 127 is connected to the second floating sleeve 131. The second elastic member 129 is disposed between the bottom walls of the second connecting shaft 127 and the second mounting cylinder 125.

[0072] The first mounting cylinder 122 can refer to a component used to fix the first limiting member 123 and the first connecting shaft 124. The first mounting cylinder 122 is a cylindrical sleeve. After the first elastic member 128 is inserted into the inner hole of the first mounting cylinder 122, one end of the first connecting shaft 124 is inserted into the first mounting cylinder 122, thereby fixing the first elastic member 128 inside the first mounting cylinder 122. The other end of the first connecting shaft 124 is connected to the first floating sleeve 130. The first limiting member 123 connects the first connecting shaft 124 and the cylinder wall of the first mounting cylinder 122, restricting the rotation of the first connecting shaft 124 inside the first mounting cylinder 122. Furthermore, the first floating sleeve 130 cannot rotate relative to the first connecting shaft 124 around its own axis to facilitate fixing to the nut 310; however, the first connecting shaft 124 can move relative to the first mounting cylinder 122 along its own axial direction. The first elastic element 128 is located between the bottom wall of the first mounting cylinder 122 and the first connecting shaft 124. The first elastic element 128 can push the first connecting shaft 124 and the first floating sleeve 130 toward the first connecting part 212, so that the first floating sleeve 130 can abut against the first connecting part 212 when the clamp 200 is tightened, thereby realizing the floating installation of the first floating sleeve 130.

[0073] In some examples, the first mounting cylinder 122 and the cover 121 are an integral structure, for example, the first mounting cylinder 122 and the cover 121 are made by integral injection molding.

[0074] In some examples, the first mounting cylinder 122 and the cover 121 are formed separately and then connected together. For example, the first mounting cylinder 122 and the cover 121 can be connected by screws, adhesives or snap-fits.

[0075] For example, the bottom wall of the first receiving cavity 1211 is provided with a first receiving hole 1215. The first mounting cylinder 122 can be interference-fitted or gap-fitted into the first receiving hole 1215. The first set screw 1216 passes through the outside of the cover 121 and abuts against the outer peripheral wall of the first mounting cylinder 122 to restrict the rotation of the first mounting cylinder 122 and reduce the risk of the first floating sleeve 130 rotating around its own axis.

[0076] The second mounting cylinder 125 can refer to a component used to fix the second limiting member 126 and the second connecting shaft 127. The second mounting cylinder 125 is a cylindrical sleeve. After the second elastic member 129 is inserted into the inner hole of the second mounting cylinder 125, one end of the second connecting shaft 127 is inserted into the second mounting cylinder 125, thereby fixing the second elastic member 129 inside the second mounting cylinder 125. The other end of the second connecting shaft 127 is connected to the second floating sleeve 131. The second limiting member 126 connects the second connecting shaft 127 and the cylinder wall of the second mounting cylinder 125, restricting the rotation of the second connecting shaft 127 inside the second mounting cylinder 125. The second floating sleeve 131 cannot rotate relative to the second connecting shaft 127 around its own axis to facilitate the fixing of the nut 310; however, the second connecting shaft 127 can move relative to the second mounting cylinder 125 along its own axial direction. The second elastic member 129 is located between the bottom wall of the second mounting cylinder 125 and the second connecting shaft 127. The second elastic member 129 can push the second connecting shaft 127 and the second floating sleeve 131 toward the first connecting part 212, so that the second floating sleeve 131 can abut against the first connecting part 212 during the tightening process of the clamp 200, thereby realizing the floating installation of the second floating sleeve 131.

[0077] In some examples, the second mounting cylinder 125 and the cover 121 are an integral structure, for example, the second mounting cylinder 125 and the cover 121 are manufactured by an integral injection molding process.

[0078] In some examples, the second mounting cylinder 125 and the cover 121 are formed separately and then connected together. For example, the second mounting cylinder 125 and the cover 121 can be connected by screws, adhesives or snap-fits.

[0079] For example, the bottom wall of the first receiving cavity 1211 is provided with a second receiving hole 1217. The second mounting cylinder 125 can be interference-fitted or gap-fitted into the second receiving hole 1217. The second set screw 1218 passes through the outside of the cover 121 and abuts against the outer peripheral wall of the second mounting cylinder 125 to restrict the rotation of the second mounting cylinder 125 and reduce the risk of the second floating sleeve 131 rotating around its own axis.

[0080] By adopting the technical solution of this embodiment, the first floating sleeve 130 and the second floating sleeve 131 can be floatingly installed, and the structure is simple and easy to process and manufacture.

[0081] In some embodiments, the wall of the first mounting cylinder 122 is provided with a first limiting groove 1221 extending axially therein, the first limiting member 123 is connected to the first connecting shaft 124, and the end of the first limiting member 123 is used to insert into the first limiting groove 1221; and / or, the wall of the second mounting cylinder 125 is provided with a second limiting groove 1251 extending axially therein, the second limiting member 126 is connected to the second connecting shaft 127, and the second limiting member 126 is used to insert into the second limiting groove 1251.

[0082] The first limiting groove 1221 is an elongated groove that extends along the axial direction of the first mounting cylinder 122 and penetrates the cylinder wall of the first mounting cylinder 122. The first limiting member 123 is an elongated shaft that passes through the first connecting shaft 124 and is perpendicular to the first connecting shaft 124. The end of the elongated shaft is located in the elongated groove, thereby restricting the rotation of the first connecting shaft 124 around its own axis. The elongated shaft can move within the elongated groove, thereby realizing the floating of the first floating sleeve 130. It can also limit the movement distance of the first connecting shaft 124 along its own axis, reducing the risk of the first connecting shaft 124 coming out of the first mounting cylinder 122 and improving the reliability of the connection between the first connecting shaft 124 and the first mounting cylinder 122. In addition, after the first connecting shaft 124 is inserted into the first mounting cylinder 122, the elongated shaft can pass through the elongated groove from the outside of the first mounting cylinder 122 into the first connecting shaft 124. The limiting connection operation between the first mounting cylinder 122 and the first connecting shaft 124 is simple.

[0083] The second limiting groove 1251 is an elongated groove that extends along the axial direction of the second mounting cylinder 125 and penetrates the cylinder wall of the second mounting cylinder 125. The second limiting member 126 is an elongated shaft that passes through the second connecting shaft 127 and is perpendicular to the second connecting shaft 127. The end of the elongated shaft is located in the elongated groove, thereby restricting the rotation of the second connecting shaft 127 around its own axis. The elongated shaft can move within the elongated groove, thereby realizing the floating of the second floating sleeve 131. It can also limit the movement distance of the second connecting shaft 127 along its own axis, reducing the risk of the second connecting shaft 127 coming out of the second mounting cylinder 125 and improving the reliability of the connection between the second connecting shaft 127 and the second mounting cylinder 125. In addition, after the second connecting shaft 127 is inserted into the second mounting cylinder 125, the elongated shaft can pass through the elongated groove from the outside of the second mounting cylinder 125 into the second connecting shaft 127. The limiting connection operation of the second mounting cylinder 125 and the second connecting shaft 127 is simple.

[0084] By adopting the technical solution of this embodiment, it is easy to achieve the floating installation of the first floating sleeve 130 and / or the second floating sleeve 131.

[0085] In some embodiments, the first floating sleeve 130 and the first connecting shaft 124 are detachably connected, and / or the second floating sleeve 131 and the second connecting shaft 127 are detachably connected.

[0086] The first floating sleeve 130 can be detached from the first connecting shaft 124, and the first floating sleeve 130 can be engaged with the first connecting shaft 124.

[0087] For example, the portion of the first connecting shaft 124 inserted into the first floating sleeve 130 is a square column. This square column is inserted into the square hole of the first floating sleeve 130, preventing the first floating sleeve 130 from rotating relative to the first connecting shaft 124. The first connecting shaft 124 has a first receiving hole, within which a first ejector elastic member and a first ejector ball are provided. The first ejector elastic member is used to eject a portion of the first ejector ball from the outer circumferential surface of the first connecting shaft 124. The first floating sleeve 130 is fitted over the first connecting shaft 124. The inner circumferential wall of the first floating sleeve 130 has a first receiving groove for accommodating the first ejector ball. The first floating sleeve 130 is inserted into the first connecting shaft 124... Before the moving sleeve 130, the first ejector elastic member ejects part of the first ejector ball out of the first connecting shaft 124. During the process of the first connecting shaft 124 being inserted into the first floating sleeve 130, the hole wall of the square hole of the first floating sleeve 130 pushes the first ejector ball back into the first receiving hole. When the first ejector ball is positioned opposite to the first receiving groove, the first ejector ball is locked into the first receiving groove under the action of the first ejector elastic member, thereby achieving axial positioning of the first connecting shaft 124 and the first floating sleeve 130. When the first floating sleeve 130 needs to be separated from the first connecting shaft 124, the first floating sleeve 130 can be pulled off the first connecting shaft 124 by force.

[0088] The second floating sleeve 131 can be detached from the second connecting shaft 127, and the second floating sleeve 131 can be engaged with the second connecting shaft 127.

[0089] For example, the portion of the second connecting shaft 127 inserted into the second floating sleeve 131 is a square column. This square column is inserted into the square hole of the second floating sleeve 131, preventing the second floating sleeve 131 from rotating relative to the second connecting shaft 127. The second connecting shaft 127 has a second receiving hole, within which a second ejector elastic member and a second ejector ball are provided. The second ejector elastic member is used to eject a portion of the second ejector ball from the outer circumferential surface of the second connecting shaft 127. The second floating sleeve 131 is fitted over the second connecting shaft 127. The inner circumferential wall of the second floating sleeve 131 has a second receiving groove for accommodating the second ejector ball. The second floating sleeve 131 is inserted into the second connecting shaft 127... Before the moving sleeve 131, the second ejector elastic member ejects a portion of the second ejector ball out of the second connecting shaft 127. During the process of the second connecting shaft 127 being inserted into the second floating sleeve 131, the wall of the square hole of the second floating sleeve 131 pushes the second ejector ball back into the second receiving hole. When the second ejector ball is positioned opposite to the second receiving groove, the second ejector ball is engaged in the second receiving groove under the action of the second ejector elastic member, thereby achieving axial positioning of the second connecting shaft 127 and the second floating sleeve 131. When the second floating sleeve 131 needs to be separated from the second connecting shaft 127, the second floating sleeve 131 can be forcefully pulled off the second connecting shaft 127.

[0090] By adopting the technical solution of this embodiment, the first floating sleeve 130 and the first connecting shaft 124 are detachably connected, and the first floating sleeve 130 of different sizes can be replaced to meet the disassembly requirements of different bolts 300; the second floating sleeve 131 and the second connecting shaft 127 are detachably connected, and the second floating sleeve 131 of different sizes can be replaced to meet the disassembly requirements of different bolts 300, thereby improving the applicability of the clamp fastening device.

[0091] Please refer to the following: Figure 7 and Figure 8 As shown, in some embodiments, the main body 11 further includes a first rotating shaft 1131, the mounting base 111 is provided with a first rotating hole 11112, the first rotating shaft 1131 passes through the first rotating hole 11112, one end of the first rotating shaft 1131 is connected to the first rotating sleeve 113, and the other end of the first rotating shaft 1131 is connected to the power component 112; the main body 11 further includes a second rotating shaft 1141, the mounting base 111 is provided with a second rotating hole 11113, the second rotating shaft 1141 passes through the second rotating hole 11113, one end of the second rotating shaft 1141 is connected to the second rotating sleeve 114, and the other end of the second rotating shaft 1141 is connected to the power component 112.

[0092] The first rotating hole 11112 is used to accommodate the through hole of the first rotating shaft 1131. The first rotating shaft 1131 can be fixed in the first rotating hole 11112 by bearings, so that the rotation of the first rotating shaft 1131 is smoother. The first rotating shaft 1131 is used to connect the first rotating sleeve 113 and the power component 112. The rotational power output by the power component 112 is transmitted to the first rotating shaft 1131, driving the first rotating shaft 1131 to rotate around its own axis, thereby driving the first rotating sleeve 113 to rotate.

[0093] The second rotating hole 11113 is used to accommodate the through hole of the second rotating shaft 1141. The second rotating shaft 1141 can be fixed in the second rotating hole 11113 by bearings, so that the rotation of the second rotating shaft 1141 is smoother. The second rotating shaft 1141 is used to connect the second rotating sleeve 114 and the power component 112. The rotational power output by the power component 112 is transmitted to the second rotating shaft 1141, driving the second rotating shaft 1141 to rotate around its own axis, thereby driving the second rotating sleeve 114 to rotate.

[0094] By adopting the technical solution of this embodiment, the power component 112 is connected to the first rotating sleeve 113 and the second rotating sleeve 114 respectively through the first rotating shaft 1131 and the second rotating shaft 1141, which facilitates the connection and layout between components.

[0095] In some embodiments, the first rotating sleeve 113 and the first rotating shaft 1131 are detachably connected, and / or the second rotating sleeve 114 and the second rotating shaft 1141 are detachably connected.

[0096] The first rotating sleeve 113 can be detached from the first rotating shaft 1131, and the first rotating sleeve 113 can be engaged with the first rotating shaft 1131.

[0097] For the detachable connection method of the first rotating sleeve 113 and the first rotating shaft 1131, please refer to the detachable connection method of the first floating sleeve 130 and the first connecting shaft 124.

[0098] The second rotating sleeve 114 can be detached from the second rotating shaft 1141, and the second rotating sleeve 114 can be engaged with the second rotating shaft 1141.

[0099] For the detachable connection method of the second rotating sleeve 114 and the second rotating shaft 1141, please refer to the detachable connection method of the second floating sleeve 131 and the second connecting shaft 127.

[0100] By adopting the technical solution of this embodiment, the first rotating sleeve 113 and the first rotating shaft 1131 are detachably connected, and the first rotating sleeve 113 of different sizes can be replaced to meet the disassembly requirements of different bolts 300; the second rotating sleeve 114 and the second rotating shaft 1141 are detachably connected, and the second rotating sleeve 114 of different sizes can be replaced to meet the disassembly requirements of different bolts 300, thereby improving the applicability of the clamp fastening device.

[0101] In some embodiments, the power component 112 includes a first power component 1121 and a second power component 1122. The first power component 1121 is connected to a first rotating shaft 1131 to drive the first rotating sleeve 113 to rotate around its own axis. The second power component 1122 is connected to a second rotating shaft 1141 to drive the second rotating sleeve 114 to rotate around its own axis.

[0102] The first power component 1121 drives the first rotating shaft 1131 to rotate, and the rotation of the first rotating shaft 1131 drives the first rotating sleeve 113 to rotate. The second power component 1122 drives the second rotating shaft 1141 to rotate, and the rotation of the second rotating shaft 1141 drives the second rotating sleeve 114 to rotate. The first rotating shaft 1131 and the second rotating shaft 1141 are driven by two different power components, which facilitates independent adjustment of the first rotating sleeve 113 and the second rotating sleeve 114, so as to facilitate adjustment of the tightness of the bolts 300 on both sides of the clamp 200, and ensure that the clamp 200 and the conductive rod 400 are tightly fitted.

[0103] In some examples, the first power component 1121 and the second power component 1122 can be components such as motors. The number of first power components 1121 is the same as the number of first rotating sleeves 113 and they are connected in a one-to-one correspondence. The number of second power components 1122 is the same as the number of second rotating sleeves 114 and they are connected in a one-to-one correspondence. This design allows the rotation of each first rotating sleeve 113 and each second rotating sleeve 114 to be controlled independently.

[0104] In some examples, multiple first rotating sleeves 113 may be driven by the same first power member 1121, and multiple second rotating sleeves 114 may be driven by the same second power member 1122; or, all the first rotating sleeves 113 and all the second rotating sleeves 114 may be driven by the same power member.

[0105] In some embodiments, the mounting base 111 includes a detachably connected connecting seat 1111 and a power base 1112. The connecting seat 1111 is provided with a second receiving cavity 11111, a first rotating hole 11112 and a second rotating hole 11113. A first ranging member 1301, a second ranging member 1302, a first power member 1121 and a second power member 1122 are connected to the power base 1112. The connecting seat 1111 is located between the power base 1112 and the cover 121. The first power member 1121 is detachably connected to the first rotating shaft 1131, and the second power member 1122 is detachably connected to the second rotating shaft 1141.

[0106] The mounting base 111 comprises two separable parts: a connecting seat 1111 and a power base 1112. The connecting seat 1111 supports the first rotating shaft 1131, the second rotating shaft 1141, the first rotating sleeve 113, the second rotating sleeve 114, and the second semicircular plate 220. The connecting seat 1111, the first rotating shaft 1131, the second rotating shaft 1141, the first rotating sleeve 113, and the second rotating sleeve 114 form a connecting module 1101. The power base 1112 serves as the first power component 1121 and the second power component 1122. The mounting base 111 of the power component 1122 is used to support the first power component 1121 and the second power component 1122. The power base 1112 can refer to a shell structure covering the first power component 1121 and the second power component 1122. The mounting part 1113 is connected to the power base 1112. The power base 1112, the first power component 1121, and the second power component 1122 form a power module 1102. The connecting module 1101 is connected between the power module 1102 and the cover assembly 12. The connecting module 1101 and the power module 1102 are separable.

[0107] By adopting the technical solution of this embodiment, the mounting base 111 is divided into a detachable connecting seat 1111 and a power base 1112, and the first power component 1121 is detachably connected to the first rotating shaft 1131, and the second power component 1122 is detachably connected to the second rotating shaft 1141, so that the main body 11 can be disassembled into a power module 1102 and a connecting module 1101. In this way, during the tightening process of the clamp 200, the cover assembly 12 and the connecting module 1101 can be installed on the clamp 200 first, and then the power module 1102 can be installed on the connecting module 1101. After removing the power module 1102, the cover assembly 12 and the connecting module 1101 are small in size, which facilitates the connection between the tightening device 10 and the clamp 200.

[0108] In some embodiments, the first power member 1121 includes a first rotary drive member 11211, a first rotary shaft 11212, a first connecting sleeve 11213, and a first power elastic member 11214. The first rotary drive member 11211 is connected to the power base 1112. The power base 1112 is provided with a first mounting hole 11121. The first rotary shaft 11212 and the first connecting sleeve 11213 are rotatably mounted in the first mounting hole 11121. The first rotary drive member 11211 is connected to one end of the first rotary shaft 11212. The other end of the first rotary shaft 11212 is used to insert one end of the first connecting sleeve 11213. The first rotary shaft 11211 has a back... The first rotating sleeve 113 is inserted into the other end of the first connecting sleeve 11213. The first rotating drive member 11211 drives the first rotating shaft 11212 to rotate around its own axis, thereby causing the first connecting sleeve 11213 and the first rotating shaft 1131 to rotate. The wall of the first mounting hole 11121 is provided with a first abutting protrusion 111211, which is located on the side of the first connecting sleeve 11213 facing away from the first rotating shaft 1131. The first dynamic elastic member 11214 is sleeved on the outside of the first rotating shaft 11212, and the first dynamic elastic member 11214 is located between the first abutting protrusion 111211 and the first connecting sleeve 11212. Between 3; the second power component 1122 includes a second rotary drive component 11221, a second rotary shaft 11222, a second connecting sleeve 11223, and a second power elastic component 11224. The second rotary drive component 11221 is connected to the power base 1112. The power base 1112 is provided with a second mounting hole 11122. The second rotary shaft 11222 and the second connecting sleeve 11223 are rotatably mounted in the second mounting hole 11122. The second rotary drive component 11221 is connected to one end of the second rotary shaft 11222. The other end of the second rotary shaft 11222 is used to insert one end of the second connecting sleeve 11223. The second rotary shaft 1141 faces away from the second rotary shaft 11222. The end of the rotating sleeve 114 is used to insert into the other end of the second connecting sleeve 11223. The second rotating drive member 11221 is used to drive the second rotating shaft 11222 to rotate around its own axis, thereby driving the second connecting sleeve 11223 and the second rotating shaft 1141 to rotate. The hole wall of the second mounting hole 11122 is provided with a second abutting protrusion 111221. The second abutting protrusion 111221 is located on the side of the second connecting sleeve 11223 facing away from the second rotating shaft 1141. The second dynamic elastic member 11224 is sleeved on the outside of the second rotating shaft 11222. The second dynamic elastic member 11224 is located between the second abutting protrusion 111221 and the second connecting sleeve 11223.

[0109] The first rotary drive component 11211 is a component used to output rotational power, such as a motor. One end of the first rotary shaft 11212 is connected to the output shaft of the first rotary drive component 11211. The rotational power output by the first rotary drive component 11211 is transmitted to the first connecting sleeve 11213 through the first rotary shaft 11212, and then to the first rotating shaft 1131 through the first connecting sleeve 11213, thereby driving the first rotating shaft 1131 to rotate. The output shaft of the first rotary drive component 11211 and the first rotary shaft 11212 can be directly connected, or they can be connected through components such as a universal joint.

[0110] The power base 1112 is provided with a first mounting hole 11121, which is used to receive a first connecting sleeve 11213. The other end of the first rotating shaft 11212 is inserted into the first mounting hole 11121 and into one end of the first connecting sleeve 11213. The first rotating shaft 1131 can be inserted into the first connecting sleeve 11213 from the other end of the first connecting sleeve 11213. The first connecting sleeve 11213 is used to connect the first rotating shaft 1131 and the first rotating shaft 11212. The inner hole of the first connecting sleeve 11213 is a square hole. The parts of the first rotating shaft 11212 and the first rotating shaft 1131 that are inserted into the first connecting sleeve 11213 are square columns. By using the limiting effect of the square column inserted into the square hole, the rotational power is transmitted, thereby driving the first rotating sleeve 113 to rotate.

[0111] The first mounting hole 11121 near the end of the first rotary drive member 11211 is provided with a first abutting protrusion 111211. The outer peripheral surface of the first rotating shaft 11212 is provided with a first abutting flange. The first abutting flange is located inside the first mounting hole 11121 and abuts against the first abutting protrusion 111211 to prevent the first rotating shaft 11212 from dislodging from the first mounting hole 11121. The first dynamic elastic member 11214 can be a spring. The first dynamic elastic member 11214 is sleeved on the first... Outside the rotating shaft 11212, the first dynamic elastic element 11214 is located between the first connecting sleeve 11213 and the first abutting flange. Under the elastic force of the first dynamic elastic element 11214, the first connecting sleeve 11213 can float along its own axis. Thus, when the first rotating shaft 1131 is inserted into the first connecting sleeve 11213 at an angle, the first connecting sleeve 11213 can move toward the first rotating drive element 11211, thereby guiding the first rotating shaft 1131 to be inserted into the first connecting sleeve 11213.

[0112] In some examples, the surface of the power base 1112 facing the connecting seat 1111 is provided with a first limiting plate 115. The first limiting plate 115 is provided with a first through hole 1151. The first through hole 1151 is arranged opposite to the first mounting hole 11121. The first rotating shaft 1131 can pass through the first through hole 1151 into the first connecting sleeve 11213. At the same time, the diameter of the first through hole 1151 is smaller than the diameter of the first mounting hole 11121. The periphery of the first through hole 1151 can block the first connecting sleeve 11213 to reduce the risk of the first connecting sleeve 11213 coming out of the first mounting hole 11121.

[0113] In some examples, gaskets are provided between the first abutting flange and the first blocking protrusion 111211, between the first power elastic member 11214 and the first abutting flange, between the first power elastic member 11214 and the first connecting sleeve 11213, and between the first connecting sleeve 11213 and the first limiting plate 115. The gaskets can reduce the friction of the rotation of the first rotating shaft 11212 and the first connecting sleeve 11213, which is beneficial to the rotational power output of the first rotating drive member 11211.

[0114] The second rotary drive component 11221 is a component that outputs rotational power, such as a motor. One end of the second rotary shaft 11222 is connected to the output shaft of the second rotary drive component 11221. The rotational power output by the second rotary drive component 11221 is transmitted to the second connecting sleeve 11223 through the second rotary shaft 11222, and then to the second rotating shaft 1141 through the second connecting sleeve 11223, thereby driving the second rotating shaft 1141 to rotate. The output shaft of the second rotary drive component 11221 and the second rotary shaft 11222 can be directly connected, or they can be connected through components such as a universal joint.

[0115] The power base 1112 is provided with a second mounting hole 11122, which is used to receive the second connecting sleeve 11223. The other end of the second rotating shaft 11222 is inserted into the second mounting hole 11122 and into one end of the second connecting sleeve 11223. The second rotating shaft 1141 can be inserted into the second connecting sleeve 11223 from the other end of the second connecting sleeve 11223. The second connecting sleeve 11223 is used to connect the second rotating shaft 1141 and the second rotating shaft 11222. The inner hole of the second connecting sleeve 11223 is a square hole. The part of the second rotating shaft 11222 and the second rotating shaft 1141 that is inserted into the second connecting sleeve 11223 is a square column. The limiting effect of the square column inserted into the square hole is used to realize the transmission of rotational power, thereby driving the second rotating sleeve 114 to rotate.

[0116] The second mounting hole 11122 is provided with a second abutting protrusion 111221 near the end of the second rotary drive member 11221. The outer peripheral surface of the second rotating shaft 11222 is provided with a second abutting flange. The second abutting flange is located inside the second mounting hole 11122 and abuts against the second abutting protrusion 111221 to prevent the second rotating shaft 11222 from dislodging from the second mounting hole 11122. The second dynamic elastic member 11224 can be a spring. The second dynamic elastic member 11224 is sleeved on the second... Outside the rotating shaft 11222, the second dynamic elastic element 11224 is located between the second connecting sleeve 11223 and the second abutting flange. Under the elastic force of the second dynamic elastic element 11224, the second connecting sleeve 11223 can float along its own axis. Thus, when the second rotating shaft 1141 is inserted into the second connecting sleeve 11223 at an angle, the second connecting sleeve 11223 can move toward the second rotating drive element 11221, thereby guiding the second rotating shaft 1141 to be inserted into the second connecting sleeve 11223.

[0117] In some examples, the surface of the power base 1112 facing the connecting seat 1111 is provided with a second limiting plate 116. The second limiting plate 116 is provided with a second through hole 1161. The second through hole 1161 is arranged opposite to the second mounting hole 11122. The second rotating shaft 1141 can pass through the second through hole 1161 into the second connecting sleeve 11223. At the same time, the diameter of the second through hole 1161 is smaller than the diameter of the second mounting hole 11122. The periphery of the second through hole 1161 can block the second connecting sleeve 11223 to reduce the risk of the second connecting sleeve 11223 coming out of the second mounting hole 11122.

[0118] In some examples, gaskets are provided between the second abutting flange and the second blocking protrusion 111221, between the second power elastic member 11224 and the second abutting flange, between the second power elastic member 11224 and the second connecting sleeve 11223, and between the second connecting sleeve 11223 and the second limiting plate 116. The gaskets can reduce the frictional force of the rotation of the second rotating shaft 11222 and the second connecting sleeve 11223, which is beneficial to the rotational power output of the second rotating drive member 11221.

[0119] By adopting the technical solution of this embodiment, the floating of the first connecting sleeve 11213 and the second connecting sleeve 11223 can guide the first rotating shaft 1131 and the second rotating shaft 1141 to be inserted into the first connecting sleeve 11213 and the second connecting sleeve 11223 respectively, thereby facilitating the connection between the power module 1102 and the connection module 1101.

[0120] Please refer to the following: Figure 10As shown, in some embodiments, the clamp fastening device further includes a control device 20, which includes a control cabinet 21 and a controller 22 and a torque sensor 23 connected to the control cabinet 21. The controller 22 is electrically connected to the first rotary drive 11211 and the second rotary drive 11221. When the torque sensor 23 is inserted into the first connecting sleeve 11213, the controller 22 controls the first connecting sleeve 11213 to output a first torque value, and the torque sensor 23 measures the second torque value output by the first connecting sleeve 11213. By comparing the first torque value and the second torque value, the output torque of the first connecting sleeve 11213 is calibrated. When the torque sensor 23 is inserted into the second connecting sleeve 11223, the controller 22 controls the second connecting sleeve 11223 to output a third torque value, and the torque sensor 23 measures the fourth torque value output by the second connecting sleeve 11223. By comparing the third torque value and the fourth torque value, the output torque of the second connecting sleeve 11223 is calibrated.

[0121] The control device 20 is a component used to control the output rotational power and speed of the first power component 1121 and the second power component 1122. The control device 20 includes a control cabinet 21, a controller 22 and a torque sensor 23. The control cabinet 21 is used to form a receiving space for the controller 22 and the torque sensor 23 to protect the controller 22 and the torque sensor 23. The bottom of the control cabinet 21 may be equipped with wheels to facilitate the movement of the control cabinet 21. The control device 20 and the tightening device 10 may be two separate modules, which is conducive to the miniaturization of the tightening module and facilitates connection with the clamp 200.

[0122] The controller 22 can refer to a core control unit with signal processing, logic operation and instruction output capabilities, such as MCU (microcontroller unit), PLC (programmable logic controller 22) and other components.

[0123] The torque sensor 23 is a measuring element that converts mechanical torque into an electrical signal. The torque sensor 23 can be a strain gauge torque sensor 23, a magnetoelectric torque sensor 23, a piezomagnetic torque sensor 23, etc.

[0124] The controller 22 directly manages the output of the first rotary drive 11211 and the second rotary drive 11221 via electrical connection, thereby controlling the output torque of the first connecting sleeve 11213 and the second connecting sleeve 11223. The torque sensor 23 can be inserted into the first connecting sleeve 11213 or the second connecting sleeve 11223 through a connector (e.g., a square post) to measure the output torque of the first connecting sleeve 11213 or the second connecting sleeve 11223. The number of torque sensors 23 can be one or more. If there is only one torque sensor, it measures the output torque of each first connecting sleeve 11213 and each second connecting sleeve 11223. If there are multiple torque sensors 23, they can simultaneously measure the output torque of multiple first connecting sleeves 11213, or simultaneously measure the output torque of multiple second connecting sleeves 11223, or simultaneously measure the output torque of the first connecting sleeve 11213 and the second connecting sleeve 11223 to improve measurement efficiency.

[0125] In some cases, after the clamp fastening equipment is used, there may be a deviation in the output torque of the first connecting sleeve 11213 and the output torque of the second connecting sleeve 11223, which may affect the fastening quality of the clamp 200.

[0126] A torque sensor is inserted into the first connecting sleeve 11213. Then, the controller 22 sends a command to the first rotary drive 11211, which drives the first connecting sleeve 11213 to rotate and requires the first connecting sleeve 11213 to output a first torque value. At the same time, the torque sensor 23 measures the actual second torque value of the first connecting sleeve 11213. By comparing the first torque value and the second torque value, if the first torque value and the second torque value are the same, it means that there is no deviation in the first connecting sleeve 11213. If the first torque value and the second torque value are inconsistent, the first torque value is calibrated according to the second torque value to eliminate the deviation of the first connecting sleeve 11213. The torque sensor is inserted into the second connecting sleeve 11223. Then, the controller 22 sends a command to the second rotary drive 11221. The second rotary drive 11221 drives the second connecting sleeve 11223 to rotate and requests the second connecting sleeve 11223 to output a third torque value. At the same time, the torque sensor 23 measures the actual fourth torque value of the second connecting sleeve 11223. By comparing the third torque value and the fourth torque value, if the third torque value and the fourth torque value are the same, it means that there is no deviation in the second connecting sleeve 11223. If the third torque value and the fourth torque value are inconsistent, the third torque value is calibrated according to the fourth torque value to eliminate the deviation of the second connecting sleeve 11223.

[0127] By adopting the technical solution of this embodiment, the output torque of the first connecting sleeve 11213 and the second connecting sleeve 11223 can be calibrated using the torque sensor 23 and the controller 22, eliminating the deviation of the output torque of the first connecting sleeve 11213 and the second connecting sleeve 11223, which is beneficial to improving the fastening quality of the clamp 200.

[0128] Please refer to the following: Figure 9 As shown, in some embodiments, the connector 1111 is provided with a connecting protrusion 11114, the power base 1112 is provided with a connecting hole 11124 and a locking member 11127, the connecting protrusion 11114 is inserted into the connecting hole 11124, and the locking member 11127 is used to lock the connecting protrusion 11114 in the connecting hole 11124.

[0129] The surface of the connector 1111 protrudes towards the power base 1112 to form a connecting protrusion 11114. The power base 1112 is provided with a connecting hole 11124. The connecting protrusion 11114 is inserted into the connecting hole 11124. After the connecting protrusion 11114 is inserted into the locking member 11127, the locking member 11127 locks and fixes the connecting protrusion 11114 in the connecting hole 11124, thereby realizing the fixed connection between the connecting module 1101 and the power module 1102. After the locking effect of the locking member 11127 and the connecting protrusion 11114 is released, the connecting module 1101 and the power module 1102 can be separated.

[0130] In some examples, the locking element 11127 can be a locking screw. The power base 1112 has a locking screw hole, and the outer peripheral surface of the connecting protrusion 11114 has an annular groove. The locking screw is screwed into the locking screw hole. After the connecting protrusion 11114 is inserted into the connecting hole 11124, rotating the locking screw inserts it into the annular groove, thus preventing the connecting protrusion 11114 from coming out of the connecting hole 11124, locking the connecting module 1101 and the power module 1102. Reverse rotation of the locking screw moves it out of the annular groove, releasing the locking of the connecting protrusion 11114, allowing the connecting module 1101 and the power module 1102 to be separated. Using a locking screw structure provides good stability for locking the connecting module 1101 and the power module 1102, and simplifies the locking and unlocking operations, facilitating the use of clamp fastening equipment. Of course, in other examples, locking element 11127 can be a pin, bolt 300, or other structures.

[0131] In some examples, the diameter of the connecting protrusion 11114 decreases along the direction from the connector 1111 to the power base 1112, so as to facilitate the insertion of the connecting protrusion 11114 into the connecting hole 11124.

[0132] By adopting the technical solution of this embodiment, the connection between the connecting seat 1111 and the power base 1112 is simple and easy to disassemble and assemble.

[0133] In some embodiments, the mounting base 111 is provided with a first support column 11115 and a second support column 11116. The first support column 11115 and the second support column 11116 are fixed in the second receiving cavity 11111. The first support column 11115 and the first rotating sleeve 113 are located on the same side of the first receiving cavity 1211. The second support column 11116 and the second rotating sleeve 114 are located on the same side of the second receiving cavity 11111. The first support column 11115 and the second support column 11116 are used to support the opposite sides of the second semicircular plate 220.

[0134] The first support column 11115 and the second support column 11116 are located inside the second receiving cavity 11111. The first support column 11115 and the second support column 11116 are located on opposite sides of the second receiving cavity 11111. The first support column 11115 and the first rotating sleeve 113 are located on the same side of the connecting seat 1111. The second support column 11116 and the second rotating sleeve 114 are located on the same side of the connecting seat 1111.

[0135] In some examples, the first support column 11115 may be located between two adjacent first rotating sleeves 113, or between the cavity sidewalls of the first rotating sleeve 113 and the second receiving cavity 11111, to better support the second semicircular plate 220.

[0136] In some examples, the second support column 11116 may be located between two adjacent second rotating sleeves 114, or between the cavity sidewalls of the second rotating sleeve 114 and the second receiving cavity 11111, to better support the second semicircular plate 220.

[0137] By adopting the technical solution of this embodiment, the second semicircular plate 220 is placed in the second receiving cavity 11111, and the first support column 11115 and the second support column 11116 respectively support the second connecting parts 222 on opposite sides of the second semicircular plate 220. The opposite sides of the second semicircular plate 220 are supported, and the second semicircular plate 220 has good fixation stability, which is beneficial to improving the fastening quality of the clamp 200.

[0138] In some embodiments, the cover 121 is provided with a first guide structure 1214, and the mounting base 111 is provided with a second guide structure 11123. The first guide structure 1214 and the second guide structure 11123 cooperate to guide the cover 121 and the mounting base 111 to connect.

[0139] In some examples, the first guide structure 1214 may be a guide post provided on the cover 121, and the second guide structure 11123 may be a guide hole provided on the connecting seat 1111. During the docking process of the cover 121 and the connecting seat 1111, the guide post is inserted into the guide hole, thereby guiding the cover 121 and the connecting seat 1111 to dock in a preset direction. The first guide structure 1214 and the second guide structure 11123 may also use a planar contact method to guide the cover 121 and the connecting seat 1111 to dock in a preset direction.

[0140] The number of first guide structures 1214 can be one or more. There are two first guide structures 1214. The two first guide structures 1214 can be distributed on opposite sides of the connecting seat 1111 to better guide the cover 121 and the connecting seat 1111 to connect.

[0141] By adopting the technical solution of this embodiment, during the docking process between the cover 121 and the mounting base 111, the first guide structure 1214 and the second guide structure 11123 cooperate with each other to guide the cover 121 and the mounting base 111 to dock accurately, which is beneficial to improving the fastening efficiency and fastening quality of the clamp 200.

[0142] In some embodiments, the first guide structure 1214 includes a first guide protrusion 12141 and a second guide protrusion 12142 disposed on the cover 121, and a second guide structure 11123 is formed at the corner of the mounting base 111. The first guide protrusion 12141 is used to fit against one side of the corner of the mounting base 111, and the second guide protrusion 12142 is used to fit against the other side of the corner of the mounting base 111.

[0143] By adopting the technical solution of this embodiment, the first guide protrusion 12141 and the second guide protrusion 12142 form an L-shaped structure. The L-shaped structure fits into the L-shaped surface of the corner of the connecting seat 1111. During the process of the cover 121 and the connecting seat 1111 coming together, the corner of the connecting seat 1111 is inserted into the inner side of the L-shaped structure. The first guide protrusion 12141 and the second guide protrusion 12142 limit the corner of the connecting seat 1111, thereby guiding the cover 121 and the connecting seat 1111 to accurately dock, which is beneficial to improving the fastening efficiency and fastening quality of the clamp 200.

[0144] In some embodiments, the cover 121 and the connecting seat 1111 are similar to a cuboid structure. The cover 121 is provided with a first guide protrusion 12141 and a second guide protrusion 12142 at two opposite corners. The two sets of first guide protrusions 12141 and second guide protrusions 12142 respectively cooperate with the two opposite corners of the connecting seat 1111. The two sets of first guide protrusions 12141 and second guide protrusions 12142 have a good limiting effect on the connecting seat 1111, which can better guide the cover 121 and the connecting seat 1111 to accurately align, which is beneficial to improving the fastening efficiency and fastening quality of the clamp 200.

[0145] In some embodiments, the cover 121 and the mounting base 111 are connected by a spring latch.

[0146] A spring hook and loop fastener is a connector that uses the elastic force of a spring to achieve fastening and opening functions. The spring hook and loop fastener includes a hook and loop body 11, a spring assembly, and a locking structure. The hook and loop body 11 includes a base and a hook and loop arm. The hook and loop arm is hinged to the base via the spring assembly. A fastening ring is hinged to the front end of the hook and loop arm. The base is fixed to the connecting seat 1111. The cover 121 is provided with a hook-shaped structure that cooperates with the fastening ring. When the spring hook and loop fastens the cover 121 and the connecting seat 1111, the hook and loop arm is manually pressed or pushed to compress or deform the spring. The fastening ring of the hook and loop arm is engaged in the hook-shaped structure, and the spring returns to its original position, generating elastic force to tightly fasten the two together. When the cover 121 and the connecting seat 1111 need to be separated, an external force (such as pulling upward) is applied to the hook and loop arm to overcome the spring elastic force, causing the fastening ring to disengage from the hook-shaped structure, thus achieving separation.

[0147] By adopting the technical solution of this embodiment, the cover 121 and the mounting base 111 are connected by a spring-loaded latch, which facilitates the disassembly and assembly of the cover 121 and the mounting base 111. After the cover 121 and the mounting base 111 are connected by the spring-loaded latch, the cover 121 can have a certain range of motion relative to the mounting base 111, so that the cover 121 can move relative to the mounting base 111 according to the tightening of the bolt 300, thereby allowing the tightening status of the bolt 300 to be reflected by the measuring surface 1212.

[0148] In some embodiments, the cover 121, control cabinet 21, power base 1112, and connecting seat 1111 may be made of aluminum, which helps reduce the weight of the device, facilitates movement, and ensures the structural strength and mechanical performance of the equipment. The power base 1112 and control cabinet 21 are made of aluminum sheet metal to ensure that the equipment is not contaminated or damaged.

[0149] In some embodiments, the control cabinet 21 is equipped with triangular wheels for the overall movement of the control device 20, and the material of the triangular wheels will not damage the floor of the factory workshop.

[0150] In some embodiments, the electrical connection between the controller 22 and the first rotary drive 11211, the second rotary drive 11221, the first distance measuring device 1301 and the second distance measuring device 1302 can be made by a cable. The cable is a low-smoke halogen-free flame-retardant cable to improve the stability of the equipment operation.

[0151] In some embodiments, the bolt 300 is tightened stepwise with a stepped torque to improve the tightening quality.

[0152] In specific use, the clamp fastening device of this application embodiment has the cover 121 placed on one side of the clamp 200, the bolts 300 on both sides of the clamp 200 adjusted so that the nuts 310 of the bolts 300 on both sides of the clamp 200 enter the first floating sleeve 130 and the second floating sleeve 131 respectively, the connecting seat 1111 placed on the other side of the clamp 200, the bolts 300 on both sides of the clamp 200 manually adjusted so that the nuts 320 of the bolts 300 on both sides of the clamp 200 enter the first rotating sleeve 113 and the second rotating sleeve 114 respectively, the spring buckle is locked to lock the cover 121 and the connecting seat 1111, the connecting protrusion 11114 of the connecting seat 1111 is inserted into the connecting hole 11124, and the first rotating shaft 1131 and the second rotating shaft 1141 are inserted into the first connecting sleeve 11213 and the second connecting sleeve 11223 respectively, and then the locking member 11127 is locked. Pressing the switch activates the first rotary drive unit 11211 and the second rotary drive unit 11221, which then operate automatically. The output torque of the first rotary drive unit 11211 and the second rotary drive unit 11221 can be adjusted according to the control of the controller 22. The operation is completed when the distance values ​​detected by the first distance measuring unit 1301 and the second distance measuring unit 1302 meet the conditions. After the operation is completed, the data is recorded and stored in the control device 20. Manually pushing out the control device 20 opens the spring latch, allowing the connection seat 1111 and the cover 121 to be removed, completing the entire operation process. During the process, the control cabinet 21 is equipped with a touchscreen, allowing the control device 20 to perform control-related operations through human-machine interaction. Through system integration and automatic adjustment control, automation is ultimately achieved, reducing manual labor and labor intensity. The torque sensor 23 can accurately calibrate the tightening device 10.

[0153] The operating modes of the clamp fastening device in this application embodiment include: loosening, loosening, torque tightening, distance-based tightening, and calibration. The loosening method is suitable for disassembling screws; loosening is suitable when the bolt 300 is stuck, by driving the nut 320 to reverse a certain number of turns to release the jam; torque tightening is suitable when the bolt 300 reaches a preset torque and the tightening operation is stopped. Distance-based tightening refers to the process where, during tightening, the parallelism of the clamp 200 is measured using the first distance measuring element 1301 and the second distance measuring element 1302. Based on the measured values ​​of the first distance measuring element 1301 and the second distance measuring element 1302, the tightening device 10 automatically adjusts until the first semicircular plate 210 and the second semicircular plate 220 are parallel, then the adjustment stops, and all bolts 300 are tightened simultaneously. After all bolts 300 reach the preset torque, they are held for a certain period of time to complete the tightening. Calibration refers to the process used to calibrate the output torque.

[0154] In some embodiments, the power base 1112 is provided with a handle 11125, an indicator light and a buzzer on its side. The handle 11125 facilitates the movement of the power module 1102. The inside of the handle 11125 is provided with a start button 11126. When the start button 11126 is pressed, the tightening device 10 starts, the buzzer sounds briefly and the indicator light shows red. When the start button 11126 is released, the tightening device 10 stops and the indicator light shows blue. When the start button 11126 is pressed and held, the tightening device 10 operates according to the selected working mode. After the process is completed, the buzzer sounds, the indicator light shows blue, and the power unit 112 automatically stops operating. At this time, the button is released.

[0155] In some embodiments, the mounting part 1113 is provided with a release button 11131. When the release button 11131 is in the off state, the release indicator shows green. When the release button 11131 is in the on state, the tightening device 10 starts to activate the release mode, and the release indicator shows red. At this time, other working modes cannot be selected.

[0156] The clamp fastening device of this application embodiment can realize the fastening installation and torque verification of the clamp 200. It changes the multiple reciprocating motion of the torque wrench during the fastening process to the fixed motion of the single-person hand-held tightening device 10, reducing the workload of the workers and improving work efficiency.

[0157] In some situations, personnel need to stand on an A-frame ladder and use a long-handled torque wrench for installation and torque verification. During installation, the installer's upper limbs need to move significantly. Using the clamp fastening device of this embodiment, personnel only need to hold the tightening device 10 to achieve fastening, ensuring a stable center of gravity and higher safety during use.

[0158] In some maintenance processes, to ensure that the two opposing surfaces of the first semicircular plate 210 and the second semicircular plate 220 are parallel and in full contact with the conductive rod 400, operators need to judge the parallelism by observing the number of threads protruding from the nut 320. However, due to the different rotation angles of the bolts 300, the manufacturing tolerances of the bolts 300, and errors caused by visual tilt angles, it is difficult for operators to judge the parallelism of the two opposing surfaces of the clamp 200. The clamp fastening device of this application embodiment can accurately determine whether there is a problem of non-parallelism through the control of the first measuring element 1301, the second measuring element 1302, and the mechanical structure, thus upgrading from "human prevention" to "technical prevention" and preventing deviations in maintenance quality.

[0159] The clamp fastening device of this embodiment is simple and easy to operate. A single person can complete the torque tightening of the clamp 200. Parameters are set in the controller 22, and the clamp fastening device is started. The tightening device 10 can run automatically under the control of the controller 22, simplifying the operation process and reducing the difficulty of operation. The control cabinet 21 can be equipped with a power supply to power the power component 112 and the controller 22, etc. The clamp fastening device has its own power supply, which brings convenience to the staff and eliminates the cumbersome connection of external power. In addition, the parallelism and torque tightening of the clamp 200 are completed simultaneously, eliminating the need for repeated angle adjustments by the personnel and improving work efficiency. Using the clamp fastening device of this embodiment improves work safety. Due to the stable center of gravity of the personnel, it is safer to work while standing on the A-frame ladder. At the same time, the clamp fastening device of this embodiment includes a laser rangefinder, controller 22, servo motor, etc., to monitor the parallelism of the clamp 200 and the tightening status of the bolts 300 in real time. Intelligent feedback control can ensure the quality of maintenance, thus providing dual protection and fundamental improvement in work safety and quality.

[0160] In summary, the clamp fastening device of this application embodiment has advantages such as simple operation, improved work efficiency, enhanced maintenance quality and safety.

[0161] In some embodiments, the clamp 200 fastening method employs the above-described clamp 200 fastening equipment, and the clamp 200 fastening method includes:

[0162] The first floating sleeve 130 and the second floating sleeve 131 are respectively fitted onto the nuts 310 of the bolts 300 on both sides of the clamp 200; the first rotating sleeve 113 and the second rotating sleeve 114 are respectively fitted onto the nuts 320 of the bolts 300 on both sides of the clamp 200; and the cover 121 and the mounting base 111 are connected.

[0163] The power unit 112 is activated, which drives the first rotating sleeve 113 and the second rotating sleeve 114 to tighten the nuts 320 on both sides of the clamp 200. After the nuts 320 on both sides of the clamp 200 are tightened to a preset state, the first measuring element 1301 and the second measuring element 1302 measure the distance between the measuring surface 1212 and the mounting base 111 to obtain a first distance value and a second distance value. Based on whether the difference between the first distance value and the second distance value meets a preset condition, the parallelism of the first semicircular plate 210 and the second semicircular plate 220 of the clamp 200 is determined.

[0164] Tightening the nut 320 to the preset state means that the bolts 300 on both sides of the clamp 200 are tightened in place, so as to facilitate the judgment of the parallelism of the clamp 200.

[0165] The first floating sleeve 130 and the second floating sleeve 131 are fitted onto the nuts 310 of the bolts 300 on both sides of the clamp 200. The first rotating sleeve 113 and the second rotating sleeve 114 are fitted onto the nuts 320 of the bolts 300 on both sides of the clamp 200. Then, the power unit 112 is started, and the power unit 112 drives the first rotating sleeve 113 and the second rotating sleeve 114 to rotate, thereby tightening the bolts 300 on both sides of the clamp 200 to a preset state. Since the measuring surface 1212 is perpendicular to the axis of the first floating sleeve 130, and the first floating sleeve 130 abuts against the first semicircular plate 210 through the first elastic element 128, when the tightening degree of the nuts 320 on both sides is inconsistent, the first semicircular plate 210 will tilt, causing the measuring surface 1212 to tilt, resulting in a difference in the measured values ​​of the first measuring element 1301 and the second measuring element 1302.

[0166] However, in machining and assembly, due to limitations in the measurement errors of the first measuring element 1301 and the second measuring element 1302, the fitting clearance between the sleeve and the bolt 300, and other factors related to the machining accuracy of the parts, as well as environmental factors such as vibration and temperature deformation, the fact that the distance values ​​measured by the first measuring element 1301 and the second measuring element 1302 are consistent, i.e., the difference between the two is 0, is a theoretical ideal state, which is difficult to achieve in actual operation. Therefore, the error can be defined within an acceptable range according to the actual situation, and the difference between the distance values ​​measured by the first measuring element 1301 and the second measuring element 1302 can be set within a preset condition. For example, the difference between the distance values ​​measured by the first measuring element 1301 and the second measuring element 1302 can be less than or equal to a preset threshold. The preset threshold can be, but is not limited to, 0.1mm, 0.2mm, 0.3mm, etc. As long as the difference does not exceed the preset threshold, it can be considered that the parallelism of the first semicircular plate 210 and the second semicircular plate 220 meets the fitting requirements of the conductive rod 400, reducing the risk of over-adjustment or judgment failure caused by pursuing an absolutely ideal state.

[0167] Therefore, whether the difference meets the preset conditions directly reflects the parallelism of the first semicircular plate 210 and the second semicircular plate 220, thereby determining the fit quality between the conductive rod 400 and the clamp 200. If it is found that the fit between the conductive rod 400 and the clamp 200 is not satisfactory, it can be adjusted in time, which is beneficial to improving the maintenance quality and fastening quality of the clamp 200. In addition, the clamp 200 is tightened by using the power component 112 to drive the first rotating sleeve 113 and the second rotating sleeve 114 to rotate. Compared with manual operation, the tightening efficiency of the clamp 200 is high, which is beneficial to improving the maintenance quality.

[0168] In some embodiments, if the difference between the first distance value and the second distance value is less than or equal to 0.2 mm, the first semicircular plate 210 and the second semicircular plate 220 are parallel; if the difference between the first distance value and the second distance value is greater than 0.2 mm, the first semicircular plate 210 and the second semicircular plate 220 are not parallel.

[0169] When the difference is ≤0.2mm, the tilt of the first semicircular plate 210 relative to the second semicircular plate 220 will not affect the tight fit between the clamp 200 and the conductive rod 400 and the quality of power transmission; if the difference is >0.2mm, problems such as poor local contact and increased resistance may occur. Therefore, setting the preset threshold to 0.2mm can better ensure the tight fit between the clamp 200 and the conductive rod 400 and the quality of power transmission.

[0170] In some embodiments, the power component 112 includes a first power component 1121 and a second power component 1122. The first power component 1121 is connected to the first rotating sleeve 113 to drive the first rotating sleeve 113 to rotate around its own axis. The second power component 1122 is connected to the second rotating sleeve 114 to drive the second rotating sleeve 114 to rotate around its own axis. The nuts 320 located on both sides of the clamp 200 are the first nut and the second nut, respectively. The first rotating sleeve 113 is sleeved on the first nut, and the second rotating sleeve 114 is sleeved on the second nut.

[0171] If the difference between the first distance value and the second distance value is greater than 0.2mm, the first semicircular plate 210 and the second semicircular plate 220 are not parallel, and an adjustment operation is performed.

[0172] The adjustment operation includes: calculating the first rotation angle of the first nut and the second rotation angle of the second nut based on the difference between the first distance value and the second distance value; and starting the first power component 1121 and the second power component 1122 to tighten the first nut and the second nut based on the calculated first rotation angle and the second rotation angle.

[0173] The first power component 1121 drives the first rotating sleeve 113, and the second power component 1122 drives the second rotating sleeve 114, so that the tightening and loosening actions of the nuts 320 on both sides can be controlled independently, which facilitates the adjustment of the clamp 200.

[0174] The tilt angle of the first semicircular plate 210 relative to the second semicircular plate 220 is calculated based on the difference. Then, the first rotation angle of the first nut and the second rotation angle of the second nut are calculated based on the tilt angle. This quantitative calculation upgrades the adjustment from an empirical operation to a precise calculation, which helps reduce the risk of over-adjustment or under-adjustment and also saves adjustment time. Based on the calculated first rotation angle of the first nut and second rotation angle of the second nut, the first power component 1121 and the second power component 1122 are activated, which can realize the differentiated movement of the nuts 320 on both sides of the clamp 200, which helps to improve adjustment efficiency.

[0175] In some embodiments, if the first nut is too tight, the first nut is loosened by a first rotation angle and then the second nut is tightened by a second rotation angle; if the second nut is too tight, the second nut is loosened by a second rotation angle and then the first nut is tightened by a first rotation angle.

[0176] When the nuts 320 on both sides are subjected to unbalanced forces, an overtightened nut 320 on one side will exert a greater tensile force on the first semicircular plate 210, causing it to tilt to that side and resulting in the first semicircular plate 210 and the second semicircular plate 220 becoming non-parallel. In this embodiment, the nut 320 on the overtightened side is tightened first to release the excess pressure, and then the other side is tightened to supplement the necessary pressure, ultimately restoring the first semicircular plate 210 to a state parallel to the second semicircular plate 220. This step of loosening first and then tightening reduces the risk of plastic deformation of the bolt 300 on the overtightened side due to continuous stress, thus improving the quality of maintenance.

[0177] In some embodiments, the first rotation angle and the second rotation angle are equal.

[0178] When the first nut is too tight, causing the first semicircular plate 210 to tilt, loosening the first nut at the first rotation angle will release a certain amount of tension, while tightening the second nut at the same second rotation angle will increase the tension by the same amount. The changes in force on both sides are equal and opposite in direction, which can correct the tilt while maintaining the balance of the overall clamping force of the clamp 200, thereby improving the overall stability of the clamping force of the clamp 200 on the conductive rod 400. The same applies if the second nut is too tight.

[0179] In some embodiments, the adjustment operation further includes: after the first nut and the second nut are tightened, the first measuring element 1301 and the second measuring element 1302 measure the distance between the measuring surface 1212 and the mounting base 111 again, and obtain the first distance value and the second distance value again.

[0180] If the difference between the first distance value and the second distance value is less than or equal to 0.2mm, the fastening operation of clamp 200 is completed;

[0181] If the difference between the first and second distance values ​​is greater than 0.2mm again, the adjustment operation can be repeated once or multiple times until the difference between the first and second distance values ​​is less than or equal to 0.2mm.

[0182] During the tightening of nut 320, factors such as mechanical clearance and deformation of elastic components may cause deviations between the actual adjustment effect and the theoretical calculation. Re-measuring allows for timely detection of whether the first semicircular plate 210 and the second semicircular plate 220 are parallel, reducing the possibility of insufficient tightening quality due to insufficient adjustment in one attempt. Furthermore, setting the process termination condition to a difference of less than or equal to 0.2mm ensures that the tightening operation only ends when the clamp 200 fully meets the fit requirements, reducing the quality risk of premature termination due to non-compliance.

[0183] In some embodiments, the preset state is that the nuts 320 on both sides of the clamp 200 are tightened to a preset torque.

[0184] The tightening of clamp 200 requires a process from loosening to reaching the target. If the distance measurement is initiated before nut 320 is tightened to a certain extent, the first semicircular plate 210 may be in a naturally loose state due to insufficient pressure, and the measured difference cannot reflect the true parallelism problem. However, using a preset torque as a reference ensures that nut 320 has applied a certain preload to the first semicircular plate 210, putting clamp 200 in a stable stress state during operation. The test results obtained under these conditions are more accurate.

[0185] The description of the various embodiments above tends to emphasize the differences between the various embodiments. The similarities or similarities between them can be referred to, and for the sake of brevity, they will not be repeated here.
