Description

Technical Field

[0001] The present application relates to the field of bolt technology, and in particular to a bolt fastening and disassembly device. Background Art

[0002] With the continuous development of industrial technology, the requirements for the reliability and safety of equipment connections are becoming increasingly higher. Bolts, as a traditional mechanical connection method, are widely used in various mechanical equipment and structures due to their simple structure, easy assembly and disassembly, and reliable connection.

[0003] During routine maintenance, bolts inside or outside PV panels, inverters, and other equipment may age or become damaged over time due to various factors, such as corrosion. If bolts are found to be loose, broken, or severely corroded, they should be replaced promptly.

[0004] However, in actual bolt replacement work, due to the small space where the bolts are located, it is difficult for the operation and maintenance personnel to observe the location of the bolts, and the difficulty coefficient of the operation will increase. When the bolts are located at a high position, the operation and maintenance personnel need to stand on a ladder or other high object to replace them. If the working environment is in a rugged environment, there are great hidden dangers for the operation and maintenance personnel, and there is a risk of people falling due to the instability of the lifting device. Most of the existing bolt tightening and disassembly devices have limited handle length, fixed head, and single function, which brings inconvenience and certain safety risks to the operation of the operation and maintenance personnel. Therefore, the replacement of bolts is difficult to observe and has safety hazards due to the small space and high-altitude operation, and the existing tools have single functions, which increases the difficulty and risk of the operation of the operation and maintenance personnel. Utility Model Content

[0005] The present application provides a bolt tightening and disassembly device to solve the problem that the existing bolt tightening and disassembly methods have few applicable scenarios and structural deficiencies. That is, the existing bolt tightening and disassembly tools mainly rely on manual operation, lack automatic tightening and disassembly functions, and are time-consuming and labor-intensive. In addition, operators often need to stand on climbing objects such as ladders to perform operations, especially in rugged environments, which poses a major safety hazard, and the instability of the lifting device may cause people to fall. When the working environment is high, even if people stand on climbing objects, it is difficult to see the screw area, and they can only tighten and disassemble by feel. At the same time, it is difficult for tightening and disassembly tools to enter a small space, and operators need to operate with their bare hands, which increases the difficulty of operation.

[0057] In order to make the purpose, technical solutions and advantages of this application clearer, the technical solutions in this application and how the technical solutions in this application solve the above-mentioned technical problems will be clearly and completely described below with specific embodiments and in combination with the drawings in this application. Obviously, the described embodiments are part of the embodiments of this application, not all of the embodiments. The following specific embodiments can be combined with each other, and the same or similar concepts or processes may not be repeated in some embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.

[0058] The terms "first," "second," "third," "fourth," and so on (if any) in the specification and claims of this application and the drawings are used to distinguish similar objects and are not necessarily used to describe a particular order or precedence. It should be understood that the terms used in this manner are interchangeable where appropriate, so that the embodiments of the application described herein can, for example, be implemented in an order other than those illustrated or described herein.

[0059] In the embodiments of this application, words such as "exemplary" or "for example" are used to indicate examples, illustrations, or descriptions. Any embodiment or design described in this application as "exemplary" or "for example" should not be construed as being preferred or advantageous over other embodiments or designs. Rather, the use of words such as "exemplary" or "for example" is intended to present the relevant concepts in a concrete manner.

[0060] With the rapid advancement of industrial technology, the safety and reliability of equipment connections have become critical factors that cannot be ignored. Bolts, a classic mechanical fastening method, play a vital role in the construction of mechanical equipment and structures due to their simple structure, easy assembly and disassembly, and reliable connection characteristics. However, over long-term operation, bolts in equipment such as photovoltaic panels and inverters are inevitably susceptible to environmental factors such as corrosion, leading to performance degradation or even failure. Timely replacement has become an essential part of maintenance work.

[0061] However, in the practice of bolt replacement, there are many challenges. The primary difficulty lies in space limitations. Bolts are often hidden in a small space, making it difficult to visually perceive their status, which increases the difficulty of positioning and operation. For high-altitude bolts, operation and maintenance personnel need to use ladders or other climbing equipment to work, especially in complex terrain. Not only is the working environment harsh, but there is also a high risk of falling from heights. What is even more difficult is that the design of existing bolt tightening and removal tools has many limitations, such as limited handle length, non-adjustable head, and single function. These shortcomings further increase the complexity and danger of operation and maintenance work, and make operation and maintenance personnel face greater operational challenges and safety threats. Therefore, how to overcome the operational difficulties brought about by space and height, while improving the flexibility and versatility of the tools, has become an urgent problem to be solved in order to optimize the bolt replacement process and ensure operation and maintenance safety.

[0062] In response to the above problems, an embodiment of the present application provides a bolt tightening and disassembly device, which realizes the forward and reverse automatic rotation of the joint through an electric ratchet wrench, and quickly tightens or loosens the bolt. An extension rod is installed at the stationary position of the head of the electric ratchet wrench, and the extension rod is provided with a rotatable camera for photographing the position of the bolt. An adjustable bracket is fixed to the lower clamp of the electric ratchet wrench. The adjustable bracket is a segmented structure, and the length can be selected for installation according to actual conditions to create a telescopic effect, allowing users to tighten or loosen bolts at high places or in narrow spaces. At the same time, a display screen is also provided under the bracket, which is used in conjunction with the camera to allow users to observe in real time whether the position of the bolt and the tightening or loosening conditions are qualified.

[0063] The following is a detailed description of the technical solution of the present invention in conjunction with the accompanying drawings and specific embodiments. The following specific embodiments can be combined with each other, and the same or similar concepts or processes may not be repeated in some embodiments.

[0064] Figure 1 This is a schematic diagram of a bolt fastening and disassembly device provided in an embodiment of the present application, as shown in FIG. Figure 1 As shown, the embodiment of the present application provides a bolt fastening and disassembly device, comprising: an electric ratchet wrench 1, a universal joint sleeve joint 2, a camera 3, a display screen 4 and a bracket 5;

[0065] The upper end of the electric ratchet wrench 1 is connected to the sleeve to be installed through the universal joint sleeve joint 2, and the sleeve to be installed is used to tighten or remove the bolt to be processed.

[0066] In the embodiments, an electric ratchet wrench is an electric tool primarily used for tightening or loosening bolts and nuts. It combines the advantages of an electric motor and a ratchet mechanism, making operation more efficient and labor-saving. The electric ratchet wrench is primarily powered by an electric motor, reducing manual fatigue. The ratchet mechanism prevents reverse slippage during rotation, improving work efficiency.

[0067] The universal joint socket connector is a tool that connects the electric ratchet wrench and the socket to be installed. The universal joint allows the connected socket to rotate at multiple angles, providing flexible operating angles, making it easy to tighten or loosen in small or irregular spaces.

[0068] A bracket 5 is fixed to the lower end of the electric ratchet wrench 1 , and the length of the bracket 5 is adjustable.

[0069] In an embodiment, the bracket is a segmented structure, and an appropriate number of brackets can be selected for splicing according to the position of the bolts, so that the user can send the electric ratchet wrench to a high place or insert the electric ratchet wrench into a narrow gap while standing on the ground.

[0070] The camera 3 is arranged at the top of the electric ratchet wrench 1, and the display screen 4 is arranged at the lower end of the bracket 5. The camera 3 is connected to the display screen 4 through a data cable. The camera 3 is used to collect images of the bolts when tightening or disassembling the bolts, and the display screen 4 is used to display the images collected by the camera 3.

[0071] In an embodiment, the camera is usually located at the highest point of the electric ratchet wrench so that the camera can fully capture the image of the bolt. The display screen is used in conjunction with the camera. The display screen is located at the lower end of the bracket, that is, close to the user's hand, which can facilitate the user to view the picture taken by the camera and adjust the bracket length, the direction of the electric ratchet wrench, etc. in time according to the captured picture.

[0072] During use, users can judge the position of the bolts, select the appropriate number of brackets, splice the brackets, extend the electric ratchet wrench to a high place or insert it into a narrow gap, and determine the position and model of the bolts and whether the bolts need to be replaced by observing the image captured by the camera on the display screen. When the bolts need to be replaced, install the socket of the corresponding model to the bolt at the universal joint socket joint and replace the bolts while standing in place.

[0073] The electric ratchet wrench, on the other hand, features automatic tightening and disassembly, eliminating manual labor and saving time and effort. Areas that are hidden from view can be clearly displayed on the monitor by adjusting the camera. The bracket design allows users to work without having to stand on a ladder or other climbing structure, significantly reducing the risk of falls.

[0074] In some embodiments, Figure 2 A schematic diagram of the structure of an electric ratchet wrench for a bolt tightening and disassembling device provided in an embodiment of the present application is shown in FIG. Figure 2As shown, the electric ratchet wrench 1 includes: a switch 11, a power assembly 12, a housing 13, a square socket head 14, a reversing knob 15, a controller and a power module;

[0075] The head of the housing 13 is provided with a reversing knob 15 for tightening or removing the bolts;

[0076] The sleeve square head 14 is arranged at the head of the housing 13 , one end of which is connected to the reversing knob 15 , and the other end of which is connected to the universal joint sleeve joint 2 .

[0077] During use, the housing is the outer structure of the electric ratchet wrench, protecting the internal components and providing a grip. The housing is typically constructed of sturdy materials to ensure the tool's durability and reliability. A reversing knob, located at the head of the housing, changes the direction of rotation of the socket head. By rotating the reversing knob, the user can select clockwise or counterclockwise rotation to tighten or remove bolts. The socket head is connected to the reversing knob at one end and to the universal joint socket at the other end, rotating the entire universal joint socket when the reversing knob is engaged.

[0078] The power assembly 12 is detachably disposed at the bottom of the housing 13 , and the power module is located inside the housing. The power module is connected to the power assembly 12 and the reversing knob 15 , respectively.

[0079] During use, the power assembly is removably mounted on the bottom of the housing. This arrangement allows for easy maintenance, replacement, or upgrades. The power assembly may include an electric motor and a transmission mechanism that provide rotational power to drive the square head of the socket. A power module, located within the housing, is responsible for providing the required electrical energy to the electric ratchet wrench. The power module may be, for example, a rechargeable battery or an external power source connected via a power cord. The power module is separately connected to the power assembly and the reversing knob to ensure the proper functioning of the rotation and reversing functions.

[0080] The switch 11 is set on the outer wall of the shell 13, and the controller is located inside the shell. One end is connected to the power module and the other end is connected to the switch 11. It is used to control the power module to supply power to the power module based on the switching signal of the switch 11.

[0081] During use, an electric ratchet wrench is equipped with a switch that controls the start and stop of the wrench. The switch is usually located on the handle for easy operation. The controller, located inside the housing, manages the power supply and operational control of the electric ratchet wrench. Based on the on / off signal from the switch, the controller controls the power module to supply power to the power assembly. When the user presses the switch, the controller receives the signal and activates the power module, supplying power to the power assembly, thereby driving the electric ratchet wrench.

[0082] In some embodiments, Figure 3 A schematic diagram of the structure of a remote control switch for a bolt tightening and disassembly device provided in an embodiment of the present application is shown in FIG. Figure 3 As shown, the bolt tightening and disassembling device further includes: a remote control switch 6, and the electric ratchet wrench 1 further includes: a remote control module;

[0083] The remote control module is located inside the housing, is in communication with the remote control switch 6 , and is connected to the controller. The controller is also used to control the power supply module to supply power to the power supply module based on the switch signal of the remote control switch 6 .

[0084] During use, the bolt tightening and disassembly device also includes an independent remote control switch, which is in communication with the remote control module. Its signal input positive terminal (IN) and normally open terminal (NO) are connected in series to the positive terminal of the electric ratchet wrench's power supply. The controller's common terminal (COM) is connected to the positive output terminal of the electric ratchet wrench's control circuit, and the common terminal (GND) is connected to the negative terminal of the electric ratchet wrench's power supply. The remote control switch has the same function as the switch on the electric ratchet wrench. When the electric ratchet wrench is high up or in a narrow gap, it is inconvenient for the user to use the switch to start and stop the wrench. In this case, the remote control switch can be used to remotely control the electric ratchet wrench.

[0085] In some embodiments, Figure 4 A schematic structural diagram of a universal joint sleeve joint of a bolt fastening and disassembly device provided in an embodiment of the present application is shown in FIG. Figure 4 As shown, the universal joint sleeve joint 2 includes: a main sleeve 21, a secondary sleeve 22, a column 23, a main sleeve universal yoke 26 and a secondary sleeve universal yoke 27;

[0086] The main sleeve 21 is connected to the lower end of the column 23, and one end of the main sleeve 21 is provided with a main sleeve polygonal opening 211, and the other end is provided with a main sleeve universal joint fork 26;

[0087] One end of the main sleeve's polygonal opening 211 is connected to the sleeve to be installed;

[0088] The auxiliary sleeve 22 is connected to the upper end of the column 23, and the lower end of the auxiliary sleeve 22 is provided with an auxiliary sleeve square head 221, and the other end is provided with an auxiliary sleeve universal joint fork 27;

[0089] One end of the secondary sleeve square head 221 is connected to the sleeve square head 14 .

[0090] During use, the column, main sleeve, and auxiliary sleeve are typically constructed from high-strength materials to ensure sufficient strength and durability during use. The other end of the main sleeve is equipped with a main sleeve polygonal opening. This opening can be hexagonal or other polygonal in shape to ensure a tight fit with the sleeve to be installed. The size and shape of the polygonal opening should match the interface of the sleeve to be installed to ensure a stable and reliable connection. The sleeve to be installed can be quickly replaced with sleeves of different sizes to accommodate bolts of varying specifications.

[0091] The other end of the secondary sleeve is provided with a secondary sleeve square head. The square head is designed as a standard square interface to closely match the sleeve square head. The size and shape of the square head should match the interface of the sleeve square head to ensure the stability and reliability of the connection.

[0092] A yoke is a mechanical component commonly used to transmit rotational motion and torque. It plays a key role in universal joints, allowing power to be transmitted between different axes while compensating for angular misalignment. A yoke typically consists of two prongs, each connected to a different shaft. A sleeve is typically attached midway between the prongs, allowing for a certain degree of angular misalignment. The prongs and sleeve are typically connected by a bearing or pin to ensure smooth transmission of rotational motion.

[0093] In some embodiments, two through holes, one in the horizontal direction and the other in the longitudinal direction, are disposed inside the column 23 , and the two through holes are perpendicular to each other.

[0094] During use, two through holes are provided inside the column, which are vertically distributed, one close to the main sleeve and the other close to the auxiliary sleeve, and are used to rotatably connect the main sleeve and the auxiliary sleeve to the column.

[0095] In some embodiments, as Figure 4 As shown, the universal joint sleeve joint 2 further includes: a first cylindrical pin 24 and a second cylindrical pin 25;

[0096] The first cylindrical pin 24 passes through the transverse through hole of the cylinder 23, and both ends of the first cylindrical pin 24 are fixed on the main sleeve universal joint fork 26;

[0097] The second cylindrical pin 25 passes through the longitudinal through hole of the cylinder 23 , and both ends of the second cylindrical pin 25 are fixed on the auxiliary sleeve universal joint fork 27 .

[0098] During use, the cylindrical pin is cylindrical and typically made of the same material as the sleeve. Its primary function is to connect the primary and secondary sleeves to the cylinder via two through-holes extending through the cylinder. For example, the first cylindrical pin passes through the transverse through-hole and is secured at both ends to the primary sleeve's universal joint fork. At this point, the transverse through-hole in the cylinder is not connected to the first cylindrical pin, and a gap exists between the through-hole and the first cylindrical pin, allowing the cylinder or primary sleeve to rotate about the first cylindrical pin. Similarly, the secondary sleeve rotates about the second cylindrical pin. These two cylindrical pins enable universal rotation of the sleeve.

[0099] In some embodiments, Figure 5 A structural diagram of a camera of a bolt fastening and disassembly device provided in an embodiment of the present application is shown as follows: Figure 5 As shown, the camera 3 includes: a camera body 31, a first clamping portion 32 and a first extension rod 33;

[0100] One end of the first extension rod 33 is fixedly connected to the camera body 31, and the other end is fixedly connected to the first clamping portion 32;

[0101] The first clamping portion 32 is clamped on the top of the electric ratchet wrench 1 , and a non-slip member is provided on a surface contacting the top.

[0102] During use, the camera can use a high-definition or ultra-high-definition camera to ensure that the details of the operation can be clearly captured even in low-light or complex environments. In order to meet the needs, waterproof, night vision and other functions can also be added to the camera. The first extension rod is designed to be retractable and bendable, which can adapt to shooting work at different heights and angles. It can be made of lightweight and high-strength materials (such as aluminum alloy or carbon fiber) to ensure that it can remain stable and not easily deformed when bearing a certain load. For example, the two ends of the extension rod can be connected with a lock to facilitate quick installation and disassembly with the camera body and the first clamping part. An anti-slip part is provided in the middle of the first clamping part. The anti-slip part is made of a high friction coefficient or silicone material, and the surface is designed with an anti-slip texture or protrusion to increase the friction with the top of the wrench, so that it can remain stable even in a vibrating environment.

[0103] In some embodiments, Figure 6 A schematic diagram of the structure of a display screen of a bolt fastening and disassembly device provided in an embodiment of the present application is shown as follows: Figure 6 As shown, the display screen 4 includes: a display screen body 41, a second clamping portion 42 and a second extension rod 43, and the second clamping portion 42 includes: a semi-arc-shaped left clamping plate 421, a semi-arc-shaped right clamping plate 422 and a cylindrical pin 423;

[0104] The semi-arc-shaped left clamping plate 421 is connected to the semi-arc-shaped right clamping plate 422 via a cylindrical pin 423;

[0105] Insulating anti-slip pads are provided on the inner sides of the semi-arc-shaped left clamping plate 421 and the semi-arc-shaped right clamping plate 422;

[0106] One end of the second extension rod 43 is fixedly connected to the display screen body 41 , and the other end is fixedly connected to the semi-arc-shaped right clamping plate 422 .

[0107] During use, the semi-arc left splint and the semi-arc right splint are connected together by cylindrical pins to form an elliptical splint, and the cylindrical pins allow it to be flexibly opened and closed. The connection method connected by cylindrical pins allows the two splints to rotate freely on the axis of the cylindrical pins, thereby realizing the functions of clamping and releasing. This design is not only simple in structure, but also easy to operate. The anti-slip pads set on the inside of the splint can ensure that the display screen will not slide during operation. The second extension rod has the same structure and material as the first extension rod. The second clamping part can clamp the display screen on the bracket through the extension rod. The design of the clamping part allows the user to clamp the display screen in a suitable position according to their own habits, which is convenient for the user to observe the bolts.

[0108] In some embodiments, Figure 7 A schematic structural diagram of a bracket of a bolt fastening and disassembly device provided in an embodiment of the present application is shown in FIG. Figure 7 As shown, the bracket 5 includes: a plurality of thread grooves 51, a plurality of bolts 52, a hoop and a bracket section 53, and the bracket section 53 includes: a bracket section first section 531, a bracket section last section 532 and a bracket section middle section 533; the bolts 52 are adapted to the thread grooves 51;

[0109] One end of the first bracket section 531 is fixed to the lower part of the electric ratchet wrench 1 through a clamp, and the other end is provided with a threaded groove 51;

[0110] The bottom of the bracket segment end section 532 is provided with a bolt 52;

[0111] A thread groove 51 is provided at the top of the middle section 533 of the bracket segment, and a bolt 52 is provided at the bottom.

[0112] During use, the bracket is adjustable and includes bracket segments of various specifications, each of which can be, for example, 1 meter long. The first bracket segment has a hoop at one end and a threaded groove at the other. The last bracket segment is provided with a bolt, which corresponds to the threaded groove. Aligning the bolt with the threaded groove and tightening it extends the bracket to a certain length. If the length still does not meet the working requirements, the bracket can be extended by adding an intermediate bracket segment. The intermediate bracket segment has a threaded groove at one end and a bolt at the other end, with the same bolt and threaded groove specifications as the first and last bracket segments.

[0113] During use, if only one section is required, the first section should be selected. If two sections are required, the first and last sections should be selected. If three or more sections are required, the first, last, and middle sections should be selected. Multiple middle sections can be selected. By combining different sections, a telescopic effect can be achieved.

[0114] In some embodiments, an insulating material is filled between the clamp and the electric ratchet wrench 1 .

[0115] During use, the adjustable bracket is fixed to the lower part of the electric ratchet wrench through a clamp. Considering the gap between the clamp and the wrench, it is fixed and filled with insulating material to ensure that the clamp can fit tightly with the wrench, which can prevent the bolt from rotating when the electric ratchet wrench is operating.

[0116] The process of using the device provided in the embodiment of the present application is as follows: the user visually determines the height of the bracket, selects the appropriate bracket segment to assemble it through bolts and thread grooves, and fixes the installed bracket clamp to the lower part of the electric ratchet wrench, and then connects the socket square head of the electric ratchet wrench to the secondary socket square head on the universal joint socket joint. Clamp the camera on the top of the electric ratchet wrench, and the clamping position is required not to affect the rotation of the wrench. Clamp the display screen on the bracket close to your hand. Turn on the switches of the camera and the display screen, lift the device so that the camera can capture the image of the bolt, and observe the captured image in real time through the display screen. During this process, the position of the camera bracket can be adjusted to make the picture it captures as complete and clear as possible.

[0117] Determine the specifications of the bolt and the operations required for the bolt through the display screen. After confirmation, install the socket corresponding to the bolt at the polygonal mouth of the main socket of the universal joint socket joint of the device, select the direction of the reversing button, lift the device again, align the socket and bolt according to the instructions of the camera and the display screen, use the remote control switch or the switch on the electric ratchet wrench to turn on the wrench, so that it drives the socket to rotate the bolt to tighten it.

[0118] In summary, the bolt tightening and disassembly device integrates automated tightening and disassembly functions, significantly improving work efficiency and eliminating the tedious and time-consuming traditional manual operations. Its unique feature is that it is equipped with an adjustable bracket, which allows operators to complete the work without having to climb high, greatly reducing the safety risks of high-altitude operations. For high-altitude or limited-viewing working environments, the device incorporates visual camera technology, which clearly presents bolt areas that are difficult to directly observe through the display screen, further enhancing the convenience and efficiency of operation. In addition, the head design of the wrench enables all-round rotation, enabling flexible response to tightening and disassembly operations, greatly reducing the physical burden on the operator. At the same time, all components of the device adopt a detachable structural design, which facilitates subsequent maintenance and component replacement, improving the overall maintainability and service life.
