Description

Technical Field

[0001] This invention relates to the field of testing tension clamps for multi-split transmission conductors, specifically to an X-ray testing system for tension clamps of multi-split transmission conductors. Background Technology

[0002] Tension clamps are key hardware used on tension towers (or angle towers) of multi-split transmission lines. Their core function is to reliably anchor multiple split conductors to the insulator string (or tower body), bear the full tension (pull) of the conductors, and transfer the tension to the tower foundation, while ensuring good electrical connection and necessary mechanical flexibility.

[0003] Unlike single-conductor systems, multi-branched conductors consist of multiple (typically 4, 6, 8, or more) sub-conductors bundled together. This necessitates special designs for tension clamps to handle the simultaneous anchoring and tension balance of multiple sub-conductors. Therefore, the health status of tension clamps during service becomes an extremely important maintenance parameter in power equipment maintenance.

[0004] Currently, the objects inspected for defects in tension clamps are primarily in service, thus operating at high voltages. This environment severely limits the methods of inspection. Furthermore, defects in tension clamps are often internal defects caused by crimping and fatigue. Therefore, existing technologies suitable for monitoring high-altitude, high-voltage environments primarily employ X-ray inspection. While numerous inspection devices and methods exist, their limitations in application scenarios result in significant weight, low compatibility, and, especially, the problem of image obstruction between conductors when inspecting multi-branched lines.

[0005] During the X-ray inspection process, existing X-ray inspection equipment is limited by the adjustment of the X-ray inspection position due to the side mounting or side adjustment method, which limits the X-ray inspection work. Therefore, how to avoid the limitations of the X-ray inspection position adjustment in the existing technology has become an urgent problem to be solved in the field of X-ray inspection of tension clamps for multi-split transmission conductors. Summary of the Invention

[0006] The purpose of this invention is to overcome the shortcomings of existing technologies in terms of the lack of flexibility in the inspection of tension clamps, which leads to incomplete X-ray inspection results. This invention provides an X-ray inspection system for tension clamps of multi-split transmission lines. By using a drone for hoisting, the flexibility of X-ray inspection of tension clamps is improved. Furthermore, a height difference is created between the X-ray machine and the detector by using a height-adjustable detector lifting assembly and an X-ray machine lifting assembly, thereby achieving a more comprehensive X-ray inspection of tension clamps.

[0007] The objective of this invention is mainly achieved through the following technical solutions:

[0008] An X-ray inspection system for tension clamps of multi-split transmission conductors includes a support frame, a drone mount fixed above the support frame, and a detection lifting assembly and a X-ray lifting assembly inside the support frame.

[0009] The detection lifting assembly is equipped with a detector, and the radiation lifting assembly is equipped with a radiation machine assembly;

[0010] The radiation emission direction of the radiation machine assembly can be adjusted circumferentially around its own axis, and the detector can move horizontally on the detection lifting assembly.

[0011] Currently, due to the need for high safety assurance of tension clamps in multi-split conductors to ensure sufficient electrical safety, routine X-ray inspection of tension clamps is required to ensure their health. X-ray inspection of tension clamps in multi-split transmission conductors is usually conducted manually. However, manual inspection is inefficient, dangerous, and lacks flexibility, resulting in incomplete X-ray inspection results. This makes it impossible to accurately and efficiently assess the health status of the tension clamps, leading to accidental damage and other problems, thus posing a high risk of electrical safety accidents.

[0012] In this invention, a support frame is used as the support base, and a drone is connected to it via a drone mount. The drone is used to carry the detection lifting assembly and the X-ray lifting assembly to perform X-ray inspection on the tension clamp. Since the X-ray inspection process requires the X-ray machine assembly to emit X-rays and irradiate the detector to form an image, the health status of the tension clamp is detected through the combined action of the X-ray machine assembly and the detector.

[0013] Since the carrier frame in this invention is mounted on a drone via a drone mount for high-altitude inspection, the drone needs to mount the carrier frame above the power transmission line. When inspecting the tension clamps, sufficient flexibility is required to adjust the X-ray machine assembly to align with the tension clamps and effectively irradiate the detector. This invention utilizes a X-ray lifting assembly to mount the X-ray machine assembly and a detection lifting assembly to mount the detector. This allows both the detector and the X-ray machine assembly to adjust their heights to adapt to the inspection of tension clamps at different locations. Preferably, the detection lifting assembly is positioned above the X-ray lifting assembly, ensuring the detector's height is always higher than the X-ray machine assembly's. This ensures the X-ray emitted by the X-ray machine assembly always points upwards, preventing radiation from reaching lower areas and providing safety protection. Furthermore, since X-ray machine assemblies are generally heavy, placing them below the detector also makes their position more stable. By changing the detector's position while maintaining the X-ray machine assembly's position, X-ray inspection of different tension clamps can be performed.

[0014] In actual multi-segment transmission lines, the tension clamps and diversion clamps exist in two states: the diversion clamp is horizontal to the ground (single-circuit middle phase); the diversion clamp is vertical to the ground (single-circuit side phase, double-circuit). Therefore, during conventional X-ray inspection, the diversion clamp can obstruct the X-ray inspection equipment, preventing effective X-ray inspection of the corresponding tension clamp. In this invention, a supporting frame is used as the supporting foundation, which can effectively accommodate the X-ray lifting assembly and the detector lifting assembly between two transmission conductors. This ensures that the lifting and lowering of the X-ray machine assembly, the lifting and lowering of the detector, the rotation of the X-ray emission direction, and the horizontal movement of the detector are not obstructed by the diversion clamp. Therefore, this invention can eliminate the interference of the diversion clamp when X-ray inspecting the tension clamp. After the height of the X-ray machine assembly and the height of the detector are adjusted, the rotation of the X-ray machine assembly and the horizontal movement of the detector can be adjusted to the optimal X-ray irradiation position for X-ray inspection, thus ensuring that the X-ray inspection results of the tension clamp are not affected by the diversion clamp.

[0015] The support frame in this invention effectively provides space for the detector and the X-ray machine assembly to perform X-ray inspections. The frame structure design effectively prevents movement of the detector and the X-ray machine assembly from affecting their positions. When the X-ray emission direction of the X-ray machine assembly can be adjusted circumferentially around its own axis, it can emit rays at different angles, thus adapting to a wider range of X-ray inspection work. The detector can move horizontally on the detector lifting assembly, ensuring smooth completion of X-ray inspections even when the X-ray emission angle changes. The frame structure effectively prevents the horizontal movement of the detector from being obstructed, thereby enabling X-ray inspection of tension clamps within a larger spatial range.

[0016] Furthermore, a first base platform and a second base platform are fixed on the supporting frame, with the second base platform located below the first base platform and perpendicular to the first base platform in the vertical direction;

[0017] The detection lifting assembly is fixed on the first base platform, and the ray lifting assembly is fixed on the second base platform.

[0018] In this invention, the first base platform is used to mount the detection lifting assembly, and the second base platform is used to mount the radiation lifting assembly. Since the radiation machine assembly needs to be lower than the detector, the second base platform is located below the first base platform. Because both the detection lifting assembly and the radiation lifting assembly need to extend and retract in the longitudinal direction to change the height of the detector and the radiation machine assembly, the first and second base platforms are staggered in the vertical region. This ensures the lifting flexibility of the radiation machine assembly and the detector, and also avoids excessively small adjustable ranges during lifting. Through the arrangement of the first and second base platforms, this invention effectively ensures the safety of the radiation machine assembly and the detector within the spatial range and effectively increases the irradiated monitoring range, thereby improving the spatial adaptability of radiation detection and enhancing the detection efficiency of tension clamps.

[0019] Furthermore, both the first base platform and the second base platform are fixed with a number of limiting ends, and a reinforcing crossbar spanning the first base platform or the second base platform is fixed between every two horizontally adjacent limiting ends.

[0020] In this invention, both the first and second base platforms need to withstand the force changes during the lifting process and bear the main weight of the X-ray detection equipment. Therefore, this invention improves the structural strength of the first and second base platforms by setting fiber ends and erecting reinforcing crossbars, thereby ensuring the safety and stability of this invention during use.

[0021] Furthermore, the detection lifting assembly includes a first winch cable, which is fixed to the first base platform. A first lifting telescopic frame is provided below the first winch cable. The upper end of the first lifting telescopic frame is fixed to the first base platform, and its lower end is provided with a horizontally extending or retracting telescopic frame. The detector is installed on the horizontally extending telescopic frame.

[0022] The X-ray lifting assembly includes a second cable, which is fixed to the second base platform. A second lifting telescopic frame is provided below the second cable. The upper end of the second lifting telescopic frame is fixed to the second base platform, and the lower end of the frame is provided with a X-ray platform. The X-ray machine assembly is installed on the X-ray platform.

[0023] The first and second lifting telescopic frames have the same structure.

[0024] In this invention, the first cable and the first base platform are fixed, so the first base platform serves as a supporting foundation for bearing the first cable. The first lifting telescopic frame can extend longitudinally by its own weight or by being driven by the first cable, and can retract longitudinally under the drive of the first cable. When the first lifting telescopic frame extends, the height of the detector decreases, and when the first lifting telescopic frame retracts, the height of the detector increases. At the same time, the lateral telescopic frame can drive the detector to move laterally in the horizontal direction. The lateral extension and retraction of the lateral telescopic frame and the longitudinal extension and retraction of the first lifting telescopic frame are independent of each other, thereby enabling the position of the detector to be moved within the spatial range.

[0025] In this invention, the second cable and the second base platform are fixed, so the second base platform serves as a supporting foundation for bearing the second cable. The second lifting telescopic frame can extend longitudinally by its own weight or by being driven by the second cable, and can retract longitudinally under the drive of the second cable. When the second lifting telescopic frame extends, the height of the X-ray machine assembly decreases, and when the second lifting telescopic frame retracts, the height of the X-ray machine assembly increases.

[0026] In this invention, the first lifting telescopic frame and the second lifting telescopic frame have the same structure, so the lifting range of the detector and the X-ray machine assembly is the same, making the distance between the X-ray machine assembly and the detector stable and controllable.

[0027] Furthermore, the detector includes a first lifting end head, which is fixed to the first lifting telescopic frame. One end of the transverse telescopic frame is fixed to the first lifting end head, and the other end is fixed to a detection connection end head. A plate mounting frame is fixed below the detection connection end head, and a detection plate is installed inside the plate mounting frame.

[0028] In this invention, the first lifting end is used to connect the first lifting telescopic frame and the transverse telescopic frame, thereby enabling the transverse telescopic frame to obtain sufficient extension space, avoiding restriction of the transverse telescopic frame's movement, and maintaining the independence of the transverse telescopic frame and the first lifting telescopic frame. The detection connection end is used to connect the plate mounting frame, and the detection plate is installed in the plate mounting frame, thereby enabling the plate to remain stable during movement and reducing the number of connection points on the detection plate, thus preventing the detection plate from undergoing local deformation under external forces.

[0029] Furthermore, the X-ray machine assembly includes a X-ray mounting frame, which is fixed to the X-ray platform. The X-ray machine is rotatably connected inside the X-ray mounting frame, and a rotary motor for driving the X-ray machine to rotate is installed on the X-ray mounting frame.

[0030] A stabilizing reinforcing plate is provided on the side of the radiation mounting frame. One side of the stabilizing reinforcing plate is fixed to the radiation mounting frame, and the other side is fixed to the radiation platform.

[0031] In this invention, the X-ray platform is used to support the weight of the X-ray machine components, the X-ray mounting frame is used to provide installation space for the X-ray machine, and the rotation of the X-ray machine is driven by a rotating motor mounted on the X-ray mounting frame, thereby changing the X-ray emission direction of the X-ray machine. By changing the X-ray emission direction and coordinating with the position adjustment of the detector, the X-ray detection of tension clamps in a larger space can be effectively covered.

[0032] The stabilizing reinforcement plate can enhance the stability of the radiation mount and improve the overall integrity of the radiation mount and the radiation platform, thereby enabling the radiation mount to remain stable when the rotating motor is working and also enabling the radiation emission direction to remain stable when the adjustment is finished.

[0033] Furthermore, the first lifting telescopic frame includes a platform connecting frame, which is fixedly connected to the first base platform. A lifting frame is fixed below the platform connecting frame. The lifting frame contains several sets of parallel second sliding frames, with two adjacent second sliding frames slidably connected. A first sliding frame is slidably connected within the second sliding frame. A connecting seat is fixed at the bottom of the first sliding frame, and several fixed frames are fixed on the connecting seat. Each fixed frame is equipped with a lifting pulley.

[0034] The first winch is fixedly connected to the platform connecting frame. The rope inside the first winch extends toward and passes through the lifting pulley. The first winch and the lifting pulley form a movable pulley.

[0035] In this invention, the first lifting telescopic frame is fixed to the first base platform via a platform connecting frame, thereby making the first base platform the supporting foundation for the first lifting telescopic frame. The lifting frame is used to accommodate the second sliding frame and the first sliding frame. Two adjacent second sliding frames are slidably connected, and the sliding range of the second sliding frame is the length of the adjacent second sliding frame. Since the adjacent second sliding frames are in a connected state, they will not detach from each other. On this basis, when one of the second sliding frames slides downward, it will cause the adjacent second sliding frame to slide downward at its lowest point, thereby increasing the overall elongation of the first lifting telescopic frame. When one of the second sliding frames slides upward, it will cause the adjacent second sliding frame to slide upward at its highest point, thereby reducing the overall elongation of the first lifting telescopic frame. In this process, the overall extension and retraction of the first lifting telescopic frame is completed.

[0036] Similarly, the first sliding frame is slidably connected to the second sliding frame, so when the first sliding frame slides down, it will drive the second sliding frame to slide down at its lowest point, thereby driving the adjacent second sliding frames to slide in turn, thus completing the extension of the first lifting telescopic frame.

[0037] When the first sliding frame slides upward, it will drive the second sliding frame to slide upward at its highest point, thereby driving the adjacent second sliding frame to slide upward, completing the retraction of the first lifting telescopic frame.

[0038] Both upward and downward sliding of the first sliding frame require a power source. In this invention, the first winch is used as the power source, and a connecting seat is set on the first sliding frame. The lifting pulley installed in the fixed frame on the connecting seat is used as a fulcrum, so that a movable pulley is formed between the first winch and the lifting pulley. When the first winch is released, the first sliding frame slides downward by its own weight, thereby gradually realizing the longitudinal extension of the entire first lifting telescopic frame. When the first winch is wound up, it can drive the first sliding frame to slide upward, thereby gradually realizing the longitudinal contraction of the entire first lifting telescopic frame.

[0039] In this invention, the release and rewinding of the first cable can effectively control the movement trajectory of the first sliding frame, thereby achieving the purpose of controlling the longitudinal extension and retraction trajectory of the first lifting telescopic frame.

[0040] Furthermore, several transverse reinforcing ribs are fixed on the lifting frame, and the transverse reinforcing ribs circumferentially surround the lifting frame.

[0041] In this invention, the transverse reinforcing ribs can enhance the overall stability of the lifting frame and prevent unstable states such as excessive swaying or violent shaking during use.

[0042] Furthermore, a walking mechanism is fixed on the support frame, which is used to drive the support frame to reciprocate.

[0043] In this invention, the walking mechanism can be used to support the weight of the carrier frame using power transmission lines, thereby enhancing the stability of the invention during X-ray inspection. The drone in this invention can carry the carrier frame using a drone mount, and can also use the walking mechanism to mount the carrier frame on the power transmission line after the drone has transported the carrier frame to the power transmission line. The drone can then be removed to maintain the high stability of the carrier frame on the power transmission line. When it is necessary to remove the invention, the drone can be connected to the drone mount to remove the entire invention from the power transmission line.

[0044] Furthermore, the walking mechanism includes a first limiting track and a second limiting track, which are symmetrically distributed on the bearing frame.

[0045] Several first wheel brackets are detachably fixed on the first limiting track, and each first wheel bracket is equipped with an obstacle-crossing wheel.

[0046] Several second wheel brackets are detachably fixed on the second limiting track. Each second wheel bracket is equipped with a load-bearing wheel. A locking component is also installed on the second wheel bracket. The locking component can press against the load-bearing wheel and stop the load-bearing wheel.

[0047] In this invention, both the first and second limiting tracks are fixed to the support frame, and the first and second limiting tracks are symmetrically distributed on the support frame to maintain the overall balance of the support frame on the power transmission line. The first wheel bracket is detachably fixed to the first limiting track, allowing it to adapt to different power transmission line spacings by adjusting the installation position. Similarly, the second wheel bracket on the second limiting track can also be adjusted to adapt to the line spacing. The support wheel is used to bear part of the weight of the support frame, and the obstacle-crossing wheel has a large diameter, so it not only bears part of the weight of the support frame but also has a certain obstacle-crossing ability. This allows the invention to cross some obstacles when adjusting its position on the power transmission line, reducing the limitations on its movement on the power transmission line.

[0048] Based on this, the X-ray lifting assembly and the detection lifting assembly described in this invention are both located within the intervals of several obstacle-crossing wheels on the first wheel body bracket and the intervals of several bearing wheels on the second wheel body bracket. If two obstacle-crossing wheels and two bearing wheels are used, then the X-ray lifting assembly and the detection lifting assembly are both located within the interval space between the two obstacle-crossing wheels and the two bearing wheels.

[0049] When the support frame is mounted on the power transmission line, since both the X-ray lifting assembly and the detection lifting assembly are located within the space between the two obstacle-crossing wheels and the two support wheels, the space between the power transmission line spacing can be effectively utilized. The X-ray detection range can be effectively adjusted by the lifting of the X-ray machine assembly, the lifting of the detector, the rotation of the X-ray machine assembly, and the horizontal movement of the detector, thereby making the X-ray detection results accurate and effective. When the walking mechanism moves with the support frame, it can also avoid the obstruction of the drain clamp, thereby increasing the X-ray detection range that the present invention can cover, and making the X-ray detection of the tension clamp more flexible.

[0050] In summary, the present invention has the following advantages compared with the prior art:

[0051] This invention utilizes a frame-like structure to mount the X-ray machine assembly and detector, enabling overall transport via drone. The X-ray and detector lifting components allow for height adjustment of the X-ray machine assembly and detector, adapting to the X-ray inspection position of the tension clamp and achieving the purpose of detecting the health status of the tension clamp. Since the tension clamps of power transmission lines are obstructed by the drain clamps, this invention uses the frame as a supporting foundation to accommodate the X-ray lifting and detector lifting components between two adjacent power transmission lines. This avoids interference from obstacles during adjustment in the X-ray inspection area. For example, the lifting of the X-ray machine assembly, the lifting of the detector, the rotation of the X-ray emission direction, and the horizontal movement of the detector are not obstructed by the drain clamps. Therefore, this invention can eliminate interference from the drain clamps when performing X-ray inspection on tension clamps.

[0052] Based on this, the first lifting end is used to connect the first lifting telescopic frame and the transverse telescopic frame, thereby enabling the transverse telescopic frame to obtain sufficient extension space, avoiding restriction of the transverse telescopic frame's movement, and maintaining the independence of the transverse telescopic frame and the first lifting telescopic frame. The detection connection end is used to connect the plate mounting frame, and the detection plate is installed in the plate mounting frame, thereby enabling the plate to remain stable during movement and reducing the number of connection points on the detection plate, thus preventing the detection plate from undergoing local deformation under the action of external forces.

Detailed Implementation

[0060] To make the objectives, technical solutions, and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the embodiments and accompanying drawings. The illustrative embodiments and descriptions of the present invention are only used to explain the present invention and are not intended to limit the present invention.

[0061] Example:

[0062] like Figures 1-5As shown, this embodiment relates to an X-ray inspection system for tension clamps of multi-split transmission conductors, including a support frame 3, a drone mount 2 fixed on the top of the support frame 3, and a detection lifting assembly 1 and a X-ray lifting assembly 13 provided inside the support frame 3, with the detection lifting assembly 1 located above the X-ray lifting assembly 13.

[0063] The detector lifting assembly 1 is equipped with a detector 7, and the radiation lifting assembly 13 is equipped with a radiation machine assembly 8;

[0064] The radiation emission direction of the X-ray machine assembly 8 can be adjusted circumferentially around its own axis, and the detector 7 can move horizontally on the detector lifting assembly 1.

[0065] In practical application, the drone hanger 2 is connected to a drone. The drone lifts the entire supporting frame 3 to the height of the power transmission line and maintains the height of the supporting frame 3. Due to the limitations of the drone structure, if the height of the X-ray machine assembly 8 and the detector 7 is fixed on the supporting frame 3, the range of X-ray detection is limited. However, the tension clamps on multi-split conductors are widely distributed. If the X-ray irradiation range is fixed, the X-ray inspection range is limited, and the purpose of effectively and comprehensively inspecting the tension clamps of multi-split conductors cannot be achieved.

[0066] In this embodiment, a detection lifting assembly 1 and a radiation lifting assembly 13 are provided inside the support frame 3. The detection lifting assembly 1 is positioned above the radiation lifting assembly 13, so that the radiation machine assembly 8 is always below the detector 7, and the radiation emitted by the radiation machine 84 is emitted upward, thereby avoiding safety risks.

[0067] The detection lifting assembly 1 can adjust the longitudinal height of the detector 7, and the X-ray lifting assembly 13 can adjust the longitudinal height of the X-ray machine assembly 8. The X-ray emission direction of the X-ray machine assembly 8 can be adjusted by its own rotation. Combined with the horizontal movement of the detector 7 on the detection lifting assembly 1, the X-ray detection range is expanded to the entire area that the detector 7 can move above the X-ray machine assembly 8, thereby effectively increasing the X-ray detection space. Based on the increased X-ray detection space, this embodiment can cover more tension clamps located at different positions in the space while the UAV maintains its position, thus improving the detection efficiency of tension clamps. It can also perform X-ray inspections of the same tension clamp from different directions and minimize overlapping inspections, thereby improving the accuracy of tension clamp health status detection.

[0068] Furthermore, a first base platform 17 and a second base platform 14 are fixed on the supporting frame 3. The second base platform 14 is located below the first base platform 17 and avoids the first base platform 17 in the vertical direction.

[0069] The detection lifting assembly 1 is fixed on the first base platform 17, and the radiation lifting assembly 13 is fixed on the second base platform 14.

[0070] Furthermore, both the first base platform 17 and the second base platform 14 are fixed with a plurality of limiting ends 15, and a reinforcing crossbar 16 spanning the first base platform 17 or the second base platform 14 is fixed between every two horizontally adjacent limiting ends 15.

[0071] In the practical application of this embodiment, both the first base platform 17 and the second base platform 14 are bearing platforms. The first base platform 17 is used to support the detection upper component, and the second base platform 14 is used to support the ray lifting component 13. The limiting ends 15 on the first base platform 17 and the second base platform 14 can be stabilized by reinforcing crossbars 16, thereby reducing the probability of instability occurring in the first base platform 17 and the second base platform 14 during use.

[0072] Furthermore, the detection lifting assembly 1 includes a first winch 101, which is fixed on the first base platform 17. A first lifting telescopic frame 18 is provided below the first winch 101. The upper end of the first lifting telescopic frame 18 is fixed to the first base platform 17, and its lower end is provided with a horizontally extending or retracting telescopic frame 75. The detector 7 is installed on the horizontally extending telescopic frame 75.

[0073] The X-ray lifting assembly 13 includes a second cable 131, which is fixed to the second base platform 14. A second lifting telescopic frame 132 is provided below the second cable 131. The upper end of the second lifting telescopic frame 132 is fixed to the second base platform 14, and the lower end of the frame is provided with a X-ray platform 83. The X-ray machine assembly 8 is installed on the X-ray platform 83.

[0074] The first lifting telescopic frame 18 and the second lifting telescopic frame 132 have the same structure.

[0075] In this embodiment, the first lifting telescopic frame 18 and the second lifting telescopic frame 132 have the same structure, so the second lifting telescopic frame 132 has all the structures of the first lifting telescopic frame 18.

[0076] The first cable 101 is fixed on the first base platform 17, thereby using the first base platform 17 for basic support. At this time, the upper end of the first lifting telescopic frame 18 is fixed on the first base platform 17, and its lower end can extend downward and drive the transverse telescopic frame 75 to move downward. The detector 7 is installed on the transverse telescopic frame 75, so the detector 7 also moves up and down with the transverse telescopic frame 75. When the first lifting telescopic frame 18 adjusts the height position of the transverse telescopic frame 75, the transverse telescopic frame 75 can horizontally move and adjust its own horizontal unfolding position at any position and drive the detector 7 to adjust its horizontal position. Therefore, the detector 7 can move to all the space range that the first lifting telescopic frame 18 and the transverse telescopic frame 75 can cover when they are extending and retracting under the combined action of the first lifting telescopic frame 18 and the transverse telescopic frame 75.

[0077] The second cable 131 is the power source for the extension and retraction of the second lifting telescopic frame 132. The upper end of the second lifting telescopic frame 132 is fixed to the second base platform 14, and its lower end can extend downwards and drive the X-ray platform 83 to rise and fall. Since the X-ray machine assembly 8 is installed on the X-ray platform 83, the X-ray machine assembly 8 can rise and fall with the second lifting telescopic frame 132. When the height position of the X-ray machine assembly 8 is determined, X-ray detection of the tension clamps in the space between the detector 7 and the X-ray machine assembly 8 can be performed simply by adjusting the position of the detector 7. Alternatively, by simultaneously adjusting the height and rotation angle of the X-ray machine assembly 8 and adaptively adjusting the height and horizontal position of the detector 7, the overlapping tension clamps can be avoided, thereby achieving the purpose of performing independent X-ray detection on each tension clamp as much as possible.

[0078] Both the first cable 101 and the second cable 131 are cable structures capable of rotating to wind up and release the cable, thereby adjusting the bottom height of the first lifting telescopic frame 18 and / or the bottom height of the second lifting telescopic frame 132 by using the winding and releasing of the cable.

[0079] Furthermore, the detector 7 includes a first lifting end 74, which is fixed to the first lifting telescopic frame 18. One end of the transverse telescopic frame 75 is fixed to the first lifting end 74, and the other end is fixed to a detection connection end 71. A plate mounting frame 73 is fixed below the detection connection end 71, and a detection plate 72 is installed inside the plate mounting frame 73.

[0080] Furthermore, the X-ray machine assembly 8 includes a X-ray mounting frame 81, which is fixed on the X-ray platform 83. A X-ray machine 84 is rotatably connected inside the X-ray mounting frame 81, and a rotary motor 85 for driving the X-ray machine 84 to rotate is installed on the X-ray mounting frame 81.

[0081] A stabilizing reinforcing plate 82 is provided on the side of the radiation mounting frame 81. One side of the stabilizing reinforcing plate 82 is fixed to the radiation mounting frame 81, and the other side is fixed to the radiation platform 83.

[0082] In this embodiment, the first lifting end 74 is used to connect the first lifting telescopic frame 18 and the transverse telescopic frame 75, thereby allowing the transverse telescopic frame 75 to obtain sufficient extension space, avoiding restriction of the movement of the transverse telescopic frame 75, and maintaining the independence of the transverse telescopic frame 75 and the first lifting telescopic frame 18. The detection connection end 71 is used to connect the plate mounting frame 73, and the detection plate 72 is installed in the plate mounting frame 73, thereby enabling the plate to remain stable during movement and reducing the number of connection points on the detection plate 72, thus preventing the detection plate 72 from undergoing local deformation under the action of external forces.

[0083] The X-ray platform 83 is used to support the weight of the X-ray machine assembly 8, and the X-ray mounting frame 81 is used to provide installation space for the X-ray machine 84. The rotation of the X-ray machine 84 is driven by the rotating motor 85 mounted on the X-ray mounting frame 81, thereby changing the X-ray emission direction of the X-ray machine 84. By changing the X-ray emission direction and coordinating with the position adjustment of the detector 7, the X-ray detection of tension clamps in a larger space can be effectively covered.

[0084] The stabilizing reinforcement plate 82 can enhance the stability of the radiation mount 81 and improve the overall integrity of the radiation mount 81 and the radiation platform 83, so that the radiation mount 81 can remain stable when the rotating motor 85 is working, and the radiation emission direction can remain stable when the adjustment is finished.

[0085] Furthermore, the first lifting telescopic frame 18 includes a platform connecting frame 181, which is fixedly connected to the first base platform 17. A lifting frame 182 is fixed below the platform connecting frame 181. The lifting frame 182 is provided with several sets of parallel second sliding frames 185. Two adjacent second sliding frames 185 are slidably connected. A first sliding frame 184 is slidably connected inside the second sliding frame 185. A connecting seat 188 is fixed at the bottom of the first sliding frame 184. Several fixing frames 187 are fixed on the connecting seat 188. Each fixing frame 187 is equipped with a lifting pulley 186.

[0086] The first winch 101 is fixedly connected to the platform connecting frame 181. The rope in the first winch 101 extends toward and passes through the lifting pulley 186. The first winch 101 and the lifting pulley 186 form a movable pulley.

[0087] Furthermore, a plurality of transverse reinforcing ribs 183 are fixed on the lifting frame 182, and the transverse reinforcing ribs 183 surround the lifting frame 182 in a circumferential manner.

[0088] In this embodiment, the platform connecting frame 181 of the first lifting telescopic frame 18 is fixed to the first base platform 17, and the connecting seat 188 of the first lifting telescopic frame 18 is fixed to the first lifting end 74.

[0089] The platform connecting frame 181 of the second lifting telescopic frame 132 is fixed to the second base platform 14, and the connecting seat 188 of the second lifting telescopic frame 132 is fixed to the radiation platform 83.

[0090] In this embodiment, the lifting frame 182 is used to accommodate the second sliding frame 185 and the first sliding frame 184. Since the second sliding frame 185 is parallel to each other and slidably connected, and the first sliding frame 184 is slidably connected to the second sliding frame 185, the first sliding frame 184 can slide downwards by its own weight. When the first sliding frame 184 slides downwards, the movable pulley connection formed by the first winch 101 and the lifting pulley 186 in the first lifting telescopic frame 18 can pull back the downward sliding tendency of the first sliding frame 184. Therefore, the first sliding frame 184 needs the first winch 101 to extend the rope. The cable can slide downwards, and when the first sliding frame 184 slides to the bottom end that is slidably connected to the second sliding frame 185, the second sliding frame 185 can be driven to slide downwards in sequence, thereby unfolding a longer telescopic length, so that the first sliding frame 184 can descend to a lower position. Since the connecting seat 188 is fixedly connected to the first sliding frame 184, the height of the detector 7 is determined by the height of the first sliding frame 184, which is determined by the length of the rope released by the first cable 101. The length that the second sliding frame 185 can extend limits the limit range that the detector 7 can reach.

[0091] In this embodiment, the extension length of the first lifting telescopic frame 18 and the second lifting telescopic frame 132 is increased by the fact that two adjacent second sliding frames 185 can form a longer connecting body by being staggered on the basis of sliding connection. Similarly, the first sliding frame 184 and the second sliding frame 185 can also form a longer connecting body by sliding stagger. Therefore, the first sliding frame 184 and the second sliding frame 185 can be extended to a longer length range by sliding stagger.

[0092] The height position of the first sliding frame 184 inside the second lifting telescopic frame 132 is determined by the length of the rope released by the second winch 131.

[0093] In this embodiment, one end of the rope coiled on the first winch 101 is wound onto the first winch 101, and the other end passes through the lifting pulley 186 in the telescopic first lifting frame 18 from the bottom and extends to the platform connecting frame 181 for fixation. When the rope has a fixed point, the lifting pulley 186 becomes a movable pulley. By winding and releasing the first winch 101, the height of the lifting pulley 186 can be effectively changed, thereby changing the height of the connecting seat 188. Therefore, the first winch 101 combined with the lifting pulley 186 in the first lifting frame 18 can effectively adjust the height of the detector 7.

[0094] One end of the rope coiled on the second helical cable 131 is wound onto the second helical cable 131, and the other end passes through the lifting pulley 186 in the second lifting telescopic frame 132 from the bottom and extends to the platform connecting frame 181 for fixation. When the rope has a fixed point, the lifting pulley 186 becomes a movable pulley. By winding and releasing the second helical cable 131, the height of the lifting pulley 186 can be effectively changed, thereby changing the height of the connecting seat 188. Therefore, the second helical cable 131 combined with the lifting pulley 186 in the second lifting telescopic frame 132 can effectively adjust the height of the X-ray machine assembly 8.

[0095] In this embodiment, the transverse telescopic frame 75 can be designed using a horizontally unfolding telescopic structure in the prior art, thereby facilitating mass production in this embodiment.

[0096] Furthermore, a walking mechanism is also fixed on the support frame 3, which is used to drive the support frame 3 to reciprocate.

[0097] Furthermore, the walking mechanism includes a first limiting track 4 and a second limiting track 12, which are symmetrically distributed on the bearing frame 3.

[0098] A plurality of first wheel brackets 5 are detachably fixed on the first limiting track 4, and each of the first wheel brackets 5 is equipped with an obstacle-crossing wheel 6.

[0099] Several second wheel brackets 11 are detachably fixed on the second limiting track 12. Each second wheel bracket 11 is equipped with a bearing wheel 10. A locking component 9 is also installed on the second wheel bracket 11. The locking component 9 can press against the bearing wheel 10 and stop the bearing wheel 10.

[0100] In this embodiment, the first limiting track 4 and the second limiting track 12 are both fixed on the bearing frame 3, and the first limiting track 4 and the second limiting track 12 are symmetrically distributed on the bearing frame 3, thereby maintaining the overall balance of the bearing frame 3 on the power transmission line. The first wheel bracket 5 is detachably fixed on the first limiting track 4, so that it can adapt to different power transmission line spacing by adjusting the installation position. Similarly, the second wheel bracket 11 on the second limiting track 12 can also be adjusted to adapt to the line spacing. The bearing wheel 10 is used to bear part of the weight of the bearing frame 3. The obstacle-crossing wheel 6 has a large wheel diameter, so the obstacle-crossing wheel 6 not only bears part of the weight of the bearing frame, but also has a certain obstacle-crossing ability, so that the present invention can cross some obstacles when moving and adjusting its position on the power transmission line, reducing the movement restrictions of the present invention on the power transmission line.

[0101] In this embodiment, the locking component 9 is implemented by a pneumatic or hydraulic rod. By setting a rubber body on the pneumatic or hydraulic rod, when the rubber body presses against the bearing wheel 10, it can play a braking role, thereby braking this embodiment and stopping the bearing wheel 10 from rotating to achieve the purpose of stopping.

[0102] In this embodiment, the obstacle-crossing wheel 6 is equipped with a drive motor. The rotation of the drive motor drives this embodiment to move on the power transmission line, thereby changing the position of this embodiment on the power transmission line and achieving the purpose of performing X-ray inspection on tension clamps at different positions.

[0103] In this embodiment, both the first limiting track 4 and the second limiting track 12 are provided with several detachable positioning holes, thereby facilitating the detachable and fixed position adjustment of the first wheel bracket 5 and the second wheel bracket 11 to adapt to the spacing of the power transmission line to be tested. The detachable fixing method in this embodiment is bolt fixing.

[0104] The specific embodiments described above further illustrate the purpose, technical solution, and beneficial effects of the present invention. It should be understood that the above description is only a specific embodiment of the present invention and is not intended to limit the scope of protection of the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
