Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of engineering detection equipment, and in particular to a gauge path detection device and a gauge path detection assembly. BACKGROUND

[0002] A drill pipe is a hollow tubular member connecting surface equipment and downhole drilling tools in a drilling engineering, which is used to transmit power, transport drilling medium, extend drilling depth and carry downhole tools. Before the drill pipe is put into the well, gauge path detection is performed to determine the reduction of the inner diameter of the drill pipe and whether there are foreign matters blocking the pipe.

[0003] In the prior art, a gauge path gauge is usually used to detect the gauge path of the drill pipe. The gauge path gauge penetrates the inside of the hollow drill pipe with a preset size, and the compliance and inner wall defects are judged by whether the gauge path gauge can smoothly pass through or contact. However, the existing gauge path gauge is prone to false judgment. Even if the gauge path gauge smoothly passes through the inside of the drill pipe, there are still foreign matters or deformation in the inside of the drill pipe, which makes the drill pipe after detection still have problems such as blockage, damage or deformation failure, which may have safety risks, and the reliability of the detection result is poor. SUMMARY

[0004] The purpose of the present application is to provide a gauge path detection device and a gauge path detection assembly to improve or solve the above technical problems in the prior art.

[0005] In a first aspect, the present application provides a gauge path detection device for detecting a to-be-detected member, the gauge path detection device comprising a cabinet, a driving member, a gauge path gauge, a torque limiter and a detection assembly, the driving member and the detection assembly being fixed to the cabinet, the driving member being drivingly connected to the gauge path gauge, the driving member being configured to drive the gauge path gauge, the torque limiter being drivingly connected between the driving member and the gauge path gauge, the torque limiter being configured to transmit torque between the driving member and the gauge path gauge, and in the case that the torque of the driving member is greater than a torque threshold, the torque limiter is configured to limit or cut off the torque transmission between the driving member and the gauge path gauge, and the detection assembly is configured to detect movement information of the gauge path gauge, and determine whether the effective gauge path of the to-be-detected member is qualified according to the movement information.

[0006] In a second aspect, the present application provides a gauge path detection assembly comprising the gauge path detection device of the first aspect and a supporting device, the supporting device being correspondingly arranged with the gauge path detection device, and the supporting device being configured to carry and adjust the relative position of the to-be-detected member, so that the to-be-detected member and the gauge path gauge are correspondingly arranged.

[0007] The technical scheme applied in the application can achieve the following beneficial effects: the driving member and the detection assembly are fixed to the cabinet body, the driving member is in transmission connection with the gauge, and the driving member is used to drive the gauge to move. The gauge moves in the inside of the to-be-detected member. When the gauge can smoothly pass through the inside of the to-be-detected member, the detection assembly determines that the effective diameter of the to-be-detected member is qualified. When there is a foreign matter in the inside of the to-be-detected member, the foreign matter will hinder the movement of the gauge, and the torque of the driving member driving the gauge will gradually increase, which is used as a judgment basis to ensure that there is no foreign matter or deformation in the inside of the to-be-detected member. During this period, when the gauge is subjected to resistance and the torque of the driving member is greater than the torque threshold, the torque limiter limits or cuts off the torque transmission between the driving member and the gauge, the torque of the driving member driving the gauge will not exceed the torque threshold, and the speed of the gauge will gradually decrease to zero or below the speed threshold. At this time, the detection assembly detects the speed of the gauge, that is, it is determined that the effective diameter of the to-be-detected member is unqualified.

[0008] Compared with the prior art, the torque limiter is arranged between the driving member and the gauge in the application. When there is a small foreign matter or slight structural deformation in the inside of the to-be-detected member, the torque limiter plays a torque restraining role, the driving force borne by the gauge is limited in a preset safe range, and the gauge cannot pass through by increasing the torque to squeeze the foreign matter or the inner wall of the to-be-detected member. The reliability of the detection result is improved. In addition, the torque limiter limits the transmission torque between the driving member and the gauge, effectively avoiding structural damage of the driving member caused by overload operation. This setting can not only protect the driving member, but also avoid false passing caused by overload of the driving member, and improve the detection reliability. BRIEF DESCRIPTION OF DRAWINGS

DETAILED DESCRIPTION

[0012] In order to make the objects, technical solutions and advantages of the present application clearer, the technical solutions of the present application will be described in detail below. Obviously, the described embodiments are only a part of the embodiments of the present application, but not all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative work belong to the scope of protection of the present application.

[0013] The terms "first", "second" and the like in the specification and claims of the present application are used to distinguish similar objects, and are not used to describe a specific order or sequence. It should be understood that the data used in this way can be interchanged under appropriate circumstances, so that the embodiments of the present application can be implemented in an order other than those illustrated or described herein, and the objects distinguished by "first", "second" and the like are generally a category, and are not limited to the number of objects, for example, the first object can be one or more. In addition, "and / or" in the specification and claims means at least one of the connected objects, and the character " / ", generally means that the front and rear associated objects are in an "or" relationship.

[0014] The applicant finds that, in the existing gauge detection process, the driving motor drives the gauge. Foreign matter exists in the drill pipe, which hinders the gauge. The gauge may be stuck, which in turn hinders the rotation of the driving motor. The driving motor outputs greater torque to overcome the resistance. However, when there is a small foreign matter in the to-be-detected member or a slight structural deformation occurs, the driving motor with increased load forces the gauge to extrude the foreign matter or the inner wall of the to-be-detected member to pass through by force. Therefore, this causes the drill pipe after passing the detection to still have the problems of jamming, damage or deformation failure, which may have safety risks.

[0015] The present application provides a gauge detection device 100, please refer to Figure 1 and Figure 2 The gauge detection device 100 is used for detecting a to-be-detected member 300. The to-be-detected member 300 includes but is not limited to a drill pipe, a conveying pipe and the like. The gauge detection device 100 can include a cabinet 110, a driving member 120, a gauge 130, a torque limiter 140 and a detection assembly 150. The driving member 120 and the detection assembly 150 are installed on the cabinet 110, and the torque limiter 140 is connected between the driving member 120 and the gauge 130.

[0016] Please refer to Figure 1 The material of the cabinet 110 can be a metal material, such as Q235 steel, aluminum alloy and the like, and is not limited. The cabinet 110 can be a frame structure, which can reduce the weight compared to a solid structure. The driving member 120 and the detection assembly 150 are fixed to the cabinet 110, and the specific fixing methods include but are not limited to threaded connection, riveting, clamping and the like. The driving member 120 is drivingly connected to the gauge 130. The driving member 120 can be a driving motor or the like, and is used to drive the gauge 130 to move. The gauge 130 can be a cylinder or the like, which can be a hollow body to reduce the driving load of the driving member 120.

[0017] Please refer to Figure 3 and Figure 4The driving member 120 is further provided with a speed reducer 122, which can be a planetary reducer or a gear reducer, without limitation. The speed reducer 122 can reduce the speed of the gauge 130 to a preset value, which can be determined according to the size of the to-be-detected member 300, without limitation. This can avoid the speed of the driving member 120 being too fast to reduce the detection stability of the gauge 130. The torque limiter 140 is drivingly connected between the driving member 120 and the gauge 130, and is used to transmit the torque between the driving member 120 and the gauge 130. When the torque of the driving member 120 is greater than a torque threshold, the torque limiter 140 limits or cuts off the torque transmission between the driving member 120 and the gauge 130. The detection assembly 150 is used to detect the motion information of the gauge 130, and determines whether the effective gauge of the to-be-detected member 300 is qualified according to the motion information. The motion information includes but is not limited to the speed and displacement of the gauge 130, without limitation. The effective gauge qualified means that the minimum channel size actually passable in the to-be-detected member 300 (such as a pipe or a drill pipe) meets the preset design specification or use requirement, without defects such as foreign matter affecting fluid conveying, tool passing, deformation or reduction in diameter. When the gauge 130 can smoothly pass through the inside of the to-be-detected member 300, the detection assembly 150 determines that the effective gauge of the to-be-detected member 300 is qualified. The gauge 130 is correspondingly arranged according to the size or shape of the inner diameter of the to-be-detected member 300. When there is foreign matter in the to-be-detected member 300, the foreign matter will hinder the movement of the gauge 130, and the torque of the driving member 120 driving the gauge 130 will gradually increase. When the torque of the driving member 120 is greater than the torque threshold, the torque limiter 140 limits or cuts off the torque transmission between the driving member 120 and the gauge 130, and the torque of the driving member 120 driving the gauge 130 will not exceed the torque threshold. The speed of the gauge 130 will gradually decrease to zero or below a speed threshold, and at this time the detection assembly 150 detects the speed of the gauge 130, that is, determines that the effective gauge of the to-be-detected member 300 is unqualified. The detection assembly 150 can control the driving member 120 to be closed, so as to avoid damaging the gauge 130 and the driving member 120.

[0018] It can be understood that, referring to Figure 4 and Figure 5The torque limiter 140 is arranged between the driving member 120 and the gauge 130. When there is a small foreign matter inside the to-be-detected member 300 or a slight structural deformation occurs, the torque limiter 140 plays a role of torque restraint. The driving force borne by the gauge 130 is limited within a preset safe range. For example, the torque limiter 140 cuts off the torque transmission between the driving member 120 and the gauge 130, and the speed of the driving member 120 decreases and stops. Alternatively, the torque limiter 140 limits the torque transmission between the driving member 120 and the gauge 130, and the driving force of the driving member 120 cannot overcome the resistance caused by the foreign matter, so that the driving member 120 cannot continue to move. At this time, the detection assembly 150 can control the driving member 120 to be closed, so as to avoid damaging the gauge 130 and the driving member 120. This avoids forcibly passing through by extruding the foreign matter or the inner wall of the to-be-detected member 300 through increasing the torque, avoids the false positive caused by the overload of the driving member 120, and improves the reliability of the detection result. In addition, the torque limiter 140 limits the transmission torque between the driving member 120 and the gauge 130, effectively avoids the structural damage of the driving member 120 caused by the overload operation. This setting can protect the driving member 120 and avoid false positive caused by the overload of the driving member 120, and improve the detection reliability.

[0019] In the embodiment of the present application, please refer to Figure 6 The gauge detection device 100 can further include a transmission member 161 and a limiting member 162. The transmission member 161 can be a gear plate and the like, and is not limited. The gauge 130 is provided with a driving chain 131. The transmission member 161 is connected to the torque limiter 140 and is in transmission connection with the driving chain 131. The limiting member 162 can be in a sheet structure and the like, and is not limited. The limiting member 162 is arranged on the circumferential side of the transmission member 161 and is arranged in a spaced manner with the transmission member 161. The limiting member limits and stops the driving chain in a direction close to the transmission member. For example, in a direction radially inward of the transmission member 161, the limiting member 162 can limit and stop the driving chain 131. The transmission member 161 is in transmission connection with the driving chain 131, and the limiting member 162 limits and stops the driving chain 131 in a direction radially inward of the transmission member 161. The limiting member 162 plays a role of restraint, which can effectively offset the centrifugal force generated when the driving chain 131 moves, avoid the driving chain 131 flying out of the preset movement track due to the centrifugal force, and ensure the structural safety and transmission stability during the operation of the whole device.

[0020] In one embodiment, please refer to Figure 5The driving chain 131 comprises a plurality of sub-segments 1311 and a plurality of connecting blocks 1312, the number of the sub-segments 1311 and the connecting blocks 1312 is 2, 3, or even more, and is not limited. The sub-segments 1311 and the connecting blocks 1312 are metal materials, such as 45 steel, stainless steel, or aluminum alloy, and are not limited. The sub-segment 1311 can be composed of two sheet structures and two column structures connecting opposite ends of the two sheet structures. Each connecting block 1312 is connected between adjacent two sub-segments 1311, and the driving chain 131 is composed of a plurality of sub-segments 1311 connected in sequence by the connecting blocks 1312. The transmission member 161 is a gear disc, and the gear disc is engaged with the driving chain 131. The transmission member 161 adopts a gear disc structure and forms an engagement transmission with the driving chain 131. The hinge design of the sub-segment 1311 and the connecting block 1312 in the application makes the driving chain 131 have a foldable characteristic. Compared with a traditional rigid driving rod, the driving chain 131 can be folded and collected in a non-working state, greatly reducing the space occupation. At the same time, the engagement transmission mode guarantees the accuracy of power transmission, and takes into account the convenience of storage and the reliability of transmission.

[0021] Preferably, the outer periphery of the driving chain 131 is further provided with a centralizer 165, which can support the sub-segment 1311 or the connecting block 1312 to ensure that the sub-segment 1311 or the connecting block 1312 is on the axis of the to-be-detected piece 300, which can avoid the driving chain 131 from being bent and unable to correctly transmit power due to gravity collapse. Further, the number of the centralizers 165 is a plurality, and the plurality of centralizers 165 are arranged on the driving chain 131 at intervals to ensure stable transmission.

[0022] In the embodiment of the application, please refer to Figure 4 The gauge detector 100 can further comprise a guide pipe 163 and a support 164. The guide pipe 163 is used to support and guide the gauge 130 into the to-be-detected piece 300. The guide pipe 163 and the gear disc are arranged at intervals, and the support 164 is located between the guide pipe 163 and the gear disc, and the support 164 is used to support the driving chain 131. The interval arrangement provides sufficient buffer space for the gauge 130 to retract. The sub-segment 1311 of the driving chain 131 can be flexibly bent in the space. A plurality of sub-segments 1311 can absorb the impact energy generated when the gauge 130 is retracted by slight bending, avoiding direct collision between the gauge 130 and the gear disc to cause structural damage. At the same time, the support 164 prevents the driving chain 131 from collapsing or deviating due to its own gravity or transmission stress, and guarantees the smoothness of the transmission process.

[0023] Preferably, the guide tube 163 has a through hole, and the gauge detection device 100 is equipped with a detection element, which can be a photoelectric sensor or a limit switch, etc. The detector is located at the through hole and is used to detect the position and speed of the gauge 130. For example, there can be multiple through holes and detectors, such as two, three, or even more. Each through hole and detector corresponds to one other. The speed of the gauge 130 can be calculated by the time difference between the gauge 130 passing through two adjacent through holes and the distance between the two adjacent through holes. Of course, the detector can also detect whether the gauge 130 has returned to the designated position to improve safety and avoid accidents caused by the gauge 130 not returning to its correct position; this will not be elaborated upon here.

[0024] Please see Figure 6 Along the first direction, the projection of the limiting member 162 is connected to or at least partially overlaps with the support member 164, and the first direction is perpendicular to the direction from the guide tube 163 to the gear disk. This arrangement enables the limiting member 162 and the support member 164 to form a continuous support and guide channel, ensuring that the drive chain 131 is always in a stable constrained and supported state when transitioning from the support member 164 to the limiting member 162, avoiding jamming or deviation of the drive chain 131 due to the gap between the two, and ensuring the continuity and stability of power transmission.

[0025] Preferably, the minimum distance between the support member 164 and the transmission member 161 is less than the length of the sub-section 1311. This dimensional design limits the movement space of the sub-section 1311 between the support member 164 and the transmission member 161, preventing the sub-section 1311 from bending unpredictably due to excessive distance. This ensures that the drive chain 131 enters the meshing area of ​​the transmission member 161 in a straight line or along a predetermined trajectory, preventing meshing failure or transmission jamming caused by bending of the sub-section 1311, and guaranteeing the smooth passage and transmission effectiveness of the drive chain 131.

[0026] In the embodiments of this application, please continue to refer to Figure 6 The support component 164 may include a support body 1641 and a support block 1642. The support body 1641 is fixed to the cabinet 110. The fixing method can be threaded connection or riveting, etc., and is not limited. The support block 1642 may be a block structure. The support block 1642 includes a first part and a second part, the width of the first part is greater than the width of the second part, and the surface of the first part near the drive chain 131 is connected to the second part. The support block 1642 is detachably installed on the support body 1641 and is used to support the drive chain 131. The support block 1642 contacts the drive chain 131 and provides support. When the support block 1642 becomes excessively worn due to long-term friction with the drive chain 131, the support block 1642 can be replaced separately by disassembly without replacing the entire support component 164, reducing equipment maintenance costs, ensuring rapid restoration of support function, and improving equipment utilization efficiency.

[0027] Please see Figure 7 The diameter detection device 100 may further include a storage tray 170, which is mounted on the cabinet 110. The storage tray 170 has a receiving channel 171, which is bent and extended to receive the drive chain 131. The storage tray 170 has an outlet communicating with the receiving channel 171. The drive chain 131 extends through the outlet and is connected to the drive component 120 for transmission. The drive chain 131 is stored in the storage tray 170 through the receiving channel 171, and the drive chain 131 meshes with the transmission component 161 through the outlet to form a transmission engagement. The bent receiving channel 171 can provide an orderly storage path for the drive chain 131 in a limited space, allowing the drive chain 131 to be arranged neatly according to a preset trajectory, avoiding entanglement and jamming caused by messy stacking. At the same time, it greatly reduces the space occupied by the drive chain 131 for storage, realizing convenient storage and quick access to the drive chain 131, and ensuring the structural compactness of the device in the non-working state and the smooth transmission during operation.

[0028] In one implementation, please refer to [link / reference needed]. Figure 7 The receiving channel 171 includes multiple straight segments 1711 and multiple bent segments 1712. The straight segments 1711 are arranged at intervals, and each bent segment 1712 connects to two adjacent straight segments 1711, so that the multiple straight segments 1711 are connected end to end. Further, the receiving channel 171 can be a reciprocating bent channel structure, or it can be a segmented spiral channel structure. The receiving channel 171 is composed of multiple spaced straight segments 1711 and bent segments 1712 connecting adjacent straight segments 1711, forming a continuous channel. This structure allows the drive chain 131 to be arranged orderly along the straight segments 1711 during storage, while the bent segments 1712 enable the direction change of the drive chain 131, preventing the drive chain 131 from tangling or knotting during storage. It also facilitates the smooth movement of the drive chain 131 along the channel during output and retraction, improving the efficiency of storage and release.

[0029] Preferably, the storage disk 170 includes a first part and a second part, with multiple straight sections 1711 disposed in the first part and multiple bent sections 1712 disposed in the second part. When it is necessary to accommodate a longer drive chain 131, the accommodating channel 171 is extended by splicing more first parts between the two second parts, thereby increasing the accommodating capacity of the storage disk 170.

[0030] In another embodiment, the receiving channel 171 is spiral-shaped. In other words, the extension path of the receiving channel 171 is spiral. The spiral structure allows the drive chain 131 to be stored layer by layer along an arc-shaped spiral trajectory, forming a compact coiled state. This not only maximizes the utilization of the internal space of the storage disk 170, but also prevents the layers of the drive chain 131 from being squeezed or tangled, ensuring the smoothness of the drive chain 131 during storage and release, and further optimizing the storage effect and space utilization.

[0031] Please refer again to the embodiments in this application. Figure 4 The drive unit 120 may be equipped with a first drive shaft 121, which is connected to the input end of the torque limiter 140. The bore detection device 100 also includes a second drive shaft 180, which is connected to the output end of the torque limiter 140 and the bore gauge 130. The detection component 150 is used to detect the motion information of the second drive shaft 180. The first drive shaft 121 and the second drive shaft 180 are connected by the torque limiter 140, and the detection component 150 collects the motion information of the second drive shaft 180 in real time. The torque limiter 140 can selectively connect or disconnect the power transmission between the two drive shafts according to a preset torque threshold. When the bore gauge 130 encounters overload resistance, the torque limiter 140 disconnects the transmission to prevent damage to the drive unit 120 and the bore gauge 130 due to overload. At the same time, the detection component 150 provides data support for the judgment of the detection results through the motion information feedback of the second drive shaft 180.

[0032] In one implementation, please refer to Figure 8 The detection component 150 may include an encoder disk 151, a sensor 152, and a controller. The controller may include a processor and a memory. The processor may include a processing chip or a microcontroller, and the memory stores control instructions for the processor to execute control operations. The sensor 152 and the controller are electrically connected, and the encoder disk 151 is connected to the second drive shaft 180. The sensor 152 is used to determine whether the effective diameter of the workpiece 300 to be detected is qualified based on motion information. The sensor 152 may be a photoelectric sensor, a contact sensor, etc., and is not limited thereto. The encoder disk 151 may be a disk with multiple notches, and is not limited thereto. The encoder disk 151 moves synchronously with the second drive shaft 180, and it provides feedback on the displacement and speed parameters of the gauge 130. The sensor 152 can acquire the displacement and speed parameters of the gauge 130. The controller determines whether the effective diameter is qualified by using a preset threshold, which improves the accuracy and objectivity of the detection results compared to the traditional manual judgment method, while realizing the automated control of the detection process.

[0033] Understandably, the motion information includes displacement and velocity. The detection component 150 determines that the effective bore of the workpiece 300 is unqualified when both the velocity and displacement of the gauge 130 are less than a velocity threshold and a displacement threshold, respectively. Conversely, it determines that the effective bore of the workpiece 300 is qualified when the displacement of the gauge 130 is equal to or greater than the displacement threshold, and controls the drive component 120 to reverse. The velocity threshold can be 0 or a specific value and is not limited. The displacement threshold can be the length of the drill pipe or the length of a desired inspection section. When both the velocity and displacement of the gauge 130 are less than the velocity threshold and a displacement threshold, the gauge 130 has not reached the predetermined position and its velocity decreases, indicating that the gauge 130 has encountered resistance and cannot pass through. The drive is then stopped by the torque limiter 140. The detection component 150 can determine that the effective bore of the workpiece 300 is unqualified, and the workpiece 300 may have problems such as foreign objects or structural deformation. When the displacement reaches or exceeds the displacement threshold, the gauge is deemed qualified, and the drive unit 120 is controlled to reverse and retract the gauge 130. At this time, the gauge 130 can move smoothly to the predetermined position, indicating that the gauge 130 can pass smoothly. At the same time, the detection component 150 avoids damage to the drive unit 120 due to continuous overload, and achieves safe retrieval of the gauge 130 through automatic reversal, thus balancing detection reliability and equipment protection functions.

[0034] To achieve the above and other related objectives, this application provides a diameter detection component 200. Please refer to [link to relevant documentation]. Figure 2 The diameter detection assembly 200 includes the diameter detection device 100 and the support device 210 as described above, with the support device 210 corresponding to the diameter detection device 100. The support device 210 is used to support and adjust the relative position of the workpiece 300 to be tested, so that the workpiece 300 to be tested and the diameter gauge 130 are correspondingly set.

[0035] Understandably, please refer to Figure 9The support device 210 may include a frame 211, a support member 212, and a rotating member 213. The support member 212 is disposed on the frame 211. The support member 212 has a support shaft, and the rotating member 213 is rotatably connected to the support shaft of the support member 212. The rotating member 213 is used to support the part 300 to be tested. The frame 211 can provide an installation reference for the support member 212. The support shaft of the support member 212 and the rotating member 213 form a rotational engagement, and the part 300 to be tested is placed on the rotating member 213 to achieve stable support. Through the rotational movement of the rotating member 213 around the support shaft, the part 300 to be tested can be driven to move along its own axial direction. The part 300 can be aligned in different directions without disassembly and repositioning, meeting the needs of multi-directional testing. At the same time, the rotational engagement reduces the frictional resistance during position adjustment, ensuring the smoothness of the adjustment process and the convenience of operation. There can be multiple support devices 210. Multiple support devices 210 simultaneously support and adjust the relative position of the part 300 to be tested, thereby improving the stability of use.
