Description

Technical Field

[0001] This utility model relates to the field of testing tension clamps on multi-split transmission conductors, specifically an X-ray testing device for tension clamps on 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 that tension clamps be specially designed 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 of tension clamp defect inspection are mostly in service, and therefore have high voltage. This environment greatly limits the inspection methods. In addition, the defects of tension clamps are often internal defects caused by crimping and fatigue. Therefore, in the existing technology, X-ray inspection is mostly used for monitoring high-altitude and high-voltage environments.

[0005] During on-site X-ray inspection, the environment is quite complex, and the X-ray inspection of tension clamps is often hindered by many factors, such as equipment movement obstruction, drainage clamps blocking the tension clamps, and drainage clamps blocking the imaging of X-ray inspection equipment.

[0006] Therefore, how to avoid the influence of the current-draining clamp or other hardware on the transmission line when the X-ray inspection equipment is used to inspect the tension clamp, so as to ensure the accuracy and effectiveness of the X-ray inspection results, has become an urgent problem to be solved in the field of X-ray inspection of tension clamps for multi-split transmission conductors. Utility Model Content

[0007] The purpose of this invention is to overcome the shortcomings of existing technologies in terms of the lack of flexibility in the detection of tension clamps, which leads to incomplete X-ray detection results. It provides an X-ray detection device for tension clamps on multi-split transmission lines. The device improves the flexibility of X-ray detection of tension clamps through a walking mechanism, and uses a liftable detector lifting component to carry the detector. The liftable X-ray lifting component carries the X-ray machine, creating a height difference between the X-ray machine and the detector, thereby achieving a more comprehensive X-ray detection of tension clamps.

[0008] The objective of this utility model is mainly achieved through the following technical solutions: An X-ray inspection device for tension clamps on multi-split transmission lines includes a support frame, within which a detection lifting assembly and a radiation lifting assembly are provided, with the detection lifting assembly located above the radiation lifting assembly. The detection lifting assembly is equipped with a detector, and the radiation lifting assembly is equipped with a radiation machine assembly; The supporting frame is fixed with a first base platform and a second base platform. The second base platform is located below the first base platform and avoids the first base platform in the vertical direction. The detection lifting assembly is fixed on the first base platform, and the radiation lifting assembly is fixed on the second base platform; A walking mechanism is also fixed on the support frame, which is used to drive the support frame to reciprocate.

[0009] 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.

[0010] This invention uses the supporting frame to support the overall weight, the detection lifting component to adjust the height of the detector, and the radiation lifting component to adjust the height of the radiation machine component. The first base platform and the second base platform can effectively use the height difference to control the extreme height of the radiation machine component and the detector, and can also avoid the lifting stroke of the radiation machine component and the lifting stroke of the detector from affecting each other.

[0011] In this embodiment, the walking mechanism is used to carry the support frame and drive the support frame to freely adjust its position on the power transmission line, thereby improving the flexibility of the X-ray detection area adjustment.

[0012] Furthermore, the walking mechanism includes a first limiting track and a second limiting track, which are symmetrically distributed on the bearing frame.

[0013] The symmetrically distributed first and second limiting tracks effectively ensure the overall stability of this invention during movement.

[0014] Furthermore, several first wheel brackets are detachably fixed on the first limiting track, and each first wheel bracket is equipped with an obstacle-crossing wheel; 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.

[0015] In this utility model, the first limiting track and the first wheel bracket are detachably fixed, thereby making the spacing of the first wheel bracket adjustable, so as to effectively adjust the wheel spacing according to the actual power transmission line spacing. The second wheel bracket and the second limiting track are similar.

[0016] The obstacle-crossing wheel on the first wheel bracket has a certain obstacle-crossing ability and load-bearing capacity, the load-bearing wheel on the second wheel bracket has a certain load-bearing capacity, and the locking component can stop the entire device by pressing against the load-bearing wheel and using friction to stop the load-bearing wheel.

[0017] Furthermore, 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.

[0018] In this invention, the X-ray machine assembly adjusts the circumferential direction of the X-ray emission by rotation, thereby effectively increasing the range of radiation that can be irradiated. The detector adjusts the X-ray detection range by horizontal movement, and the position adjustment of the detector can avoid obstacles during the position adjustment process through independent lifting and horizontal movement, thereby preventing the position adjustment of the X-ray detection area from failing due to obstruction.

[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] The first base platform and the second base platform are reinforced by connecting reinforcing crossbars at the limiting ends, thereby strengthening the load-bearing capacity of the first base platform and the second base platform. This ensures that the detection lifting assembly and the X-ray lifting assembly remain stable during operation, avoiding problems such as shaking or trembling during the X-ray detection process caused by changes in the force during lifting.

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

[0022] In this invention, the first winch and the first base platform are fixed, so the first base platform serves as a supporting foundation for bearing the first winch. The first lifting telescopic frame can extend longitudinally by its own weight or by being driven by the first winch, and can retract longitudinally under the drive of the first winch. 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. In this utility model, 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. In this invention, the first and second lifting telescopic frames 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.

[0023] 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.

[0024] 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 inside 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.

[0025] 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. 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.

[0026] 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. 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.

[0027] 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. 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.

[0028] 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 drive 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 drive 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.

[0029] 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. 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.

[0030] 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 retraction of the entire first lifting telescopic frame.

[0031] 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.

[0032] Furthermore, several transverse reinforcing ribs are fixed on the lifting frame, and the transverse reinforcing ribs circumferentially surround the lifting frame.

[0033] The transverse reinforcing ribs in this invention can enhance the overall stability of the lifting frame and prevent unstable states such as excessive swaying or violent shaking during use.

[0034] In summary, this utility model has the following advantages compared with the prior art: This invention uses a supporting frame to support the overall weight. The detection lifting component adjusts the height of the detector, and the X-ray lifting component adjusts the height of the X-ray machine assembly. The first and second base platforms effectively utilize the height difference to control the maximum height of the X-ray machine assembly and the detector, and also prevent the lifting strokes of the X-ray machine assembly and the detector from interfering with each other. Furthermore, this invention limits the carrying range of the supporting frame through a walking mechanism, and houses both the X-ray machine assembly and the detector between two power transmission lines. This eliminates the need to consider obstacles on the sides of the power transmission lines when adjusting the position of the X-ray machine assembly and the detector, thus avoiding interference from obstacles during the adjustment of the X-ray detection 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 clamp. Therefore, this invention can eliminate interference from the drain clamp when performing X-ray detection on tension clamps. Attached Figure Description

[0037] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the embodiments and accompanying drawings. The illustrative embodiments and descriptions of this utility model are only used to explain this utility model and are not intended to limit this utility model.

[0038] Example: like Figures 1-5 As shown, the X-ray detection device for tension clamps on multi-split transmission lines includes a support frame 3, and the support frame 3 is provided with a detection lifting component 1 and a X-ray lifting component 13. The detection lifting component 1 is located above the X-ray lifting component 13. The detector lifting assembly 1 is equipped with a detector 7, and the radiation lifting assembly 13 is equipped with a radiation machine assembly 88; The supporting frame 3 is fixed with a first base platform 17 and a second base platform 14. The second base platform 14 is located below the first base platform 17 and avoids the first base platform 17 in the vertical direction. The detection lifting assembly 1 is fixed on the first base platform 17, and the X-ray lifting assembly 13 is fixed on the second base platform 14; A walking mechanism is also fixed on the upper part of the support frame 3, which is used to drive the support frame 3 to reciprocate.

[0039] In this embodiment, the detector 7, X-ray machine 84, obstacle-crossing wheel 6, and load-bearing wheel 10 are all models that can be purchased on a large scale in the existing technology, which facilitates the large-scale production of this embodiment.

[0040] In practical applications, this embodiment places the supporting frame 3 on the power transmission line and uses the walking mechanism to complete the support on the power transmission line. This allows the detection lifting component 1 and the X-ray lifting component 13 to adjust the height of the X-ray detection area by using the first base platform 17 and the second base platform 14. Since the first base platform 17 and the second base platform 14 are fixed on the supporting frame 3, they can effectively control the extreme height of the X-ray machine component 88 and the detector 7 by using the height difference. This also avoids the lifting stroke of the X-ray machine component 88 and the lifting stroke of the detector 7 from interfering with each other.

[0041] This embodiment can maintain the stability of the X-ray detection process while effectively ensuring the adjustment flexibility of the X-ray detection area.

[0042] 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.

[0043] Furthermore, several first wheel brackets 5 are detachably fixed on the first limiting track 4, and each first wheel bracket 5 is equipped with an obstacle-crossing wheel 6. 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.

[0044] In this embodiment, the first limiting track 4 and the second limiting track 12 are symmetrical, so the supporting frame 3 can maintain a balanced state during walking. The first wheel bracket 5 and the second wheel bracket 11 are both adjusted according to the actual line spacing of the power transmission lines. Based on this, the X-ray machine assembly 88 and the detector 7 can be effectively accommodated between the two power transmission lines. Therefore, when there are obstacles on the power transmission lines that hinder walking, the X-ray machine assembly 88 and the detector 7 can avoid the obstacles by being set between the two power transmission lines, thereby making the walking process in this embodiment smoother.

[0045] The obstacle-crossing wheel 6 has a certain obstacle-crossing capability. For example, when the tension clamp needs to be X-rayed in this embodiment, the obstacle-crossing wheel 6 can cross the tension clamp, so that the tension clamp is in the vertical area of ​​the support frame 3. This makes it easier to adjust the position of the X-ray machine assembly 88 and the detector 7 to perform irradiation and imaging operations on the position to be tested.

[0046] Furthermore, the radiation emission direction of the radiation machine assembly 88 can be adjusted circumferentially around its own axis, and the detector 7 can move horizontally on the detector lifting assembly 1.

[0047] The X-ray machine assembly 88 adjusts the X-ray emission direction by rotating circumferentially, thereby enhancing the flexibility of the X-ray detection area position adjustment. The detector 7 can be adjusted longitudinally using the detector lifting assembly 1. Combined with the horizontal movement of the detector 7, the detector 7 can be effectively sent to a suitable imaging position. Furthermore, since the horizontal movement and lifting adjustment are independent of each other, the detector 7 also has a certain obstacle avoidance capability during the adjustment process, which can prevent the position adjustment of the detector 7 from being obstructed.

[0048] 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.

[0049] In this embodiment, the limiting end 15 improves the overall stability of the first base platform 17 and the second base platform 14 by fixing the reinforcing crossbar 16, thereby improving the overall load-bearing capacity of the detection lifting assembly 1 and the radiation lifting assembly 13.

[0050] 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. The X-ray lifting assembly 13 includes a second cable 131, which is fixed on 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 88 is installed on the X-ray platform 83. The first lifting telescopic frame 18 and the second lifting telescopic frame 132 have the same structure.

[0051] 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. 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.

[0052] 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.

[0053] 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.

[0054] Furthermore, the X-ray machine assembly 88 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. 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.

[0055] 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.

[0056] 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. 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.

[0057] 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. 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.

[0058] 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.

[0059] 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.

[0060] 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.

[0061] 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.

[0062] 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. 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.

[0063] 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.

[0064] 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.

[0065] In this embodiment, both the obstacle-crossing wheel 6 and the load-bearing wheel 10 are driven by brushless DC motors in conjunction with planetary reducers, so that each wheel can provide power and there will be no power loss during obstacle crossing, thereby improving the overall mobility of this embodiment. By driving the rotation of the motor, this embodiment moves on the power transmission line, thereby changing the position of this embodiment on the power transmission line, so as to achieve the purpose of X-ray inspection of tension clamps at different positions.

[0066] 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.

[0067] The specific embodiments described above further illustrate the purpose, technical solution, and beneficial effects of this utility model. It should be understood that the above description is only a specific embodiment of this utility model and is not intended to limit the scope of protection of this utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the scope of protection of this utility model.
