The system includes a support frame, with a first limiting rail and a second limiting rail fixed on one side of the support frame. A bounding area is formed by sequentially connecting the first and second wheel mechanisms as boundary points. The lifting trajectories of the liftable X-ray mechanism and the liftable detection mechanism are both within the vertical area covered by the bounding area. The method involves: adjusting the wheel spacing according to the line spacing of the transmission line to be inspected; adjusting the height of the liftable X-ray mechanism and the liftable detection mechanism within the support frame to correspond to the tension clamp to be inspected; and acquiring an image of the tension clamp formed on the liftable detection mechanism.

Description

Technical Field

[0001] This invention relates to the field of testing tension clamps for multi-split transmission lines, specifically to an X-ray testing system and method for tension clamps of multi-split transmission lines. 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] Because multi-split conductors have different numbers of sub-conductors and varying spacing between them, the position of the X-ray inspection device needs to be adjusted to accommodate different conductor spacings. Existing technologies require different specifications of inspection equipment to accommodate different conductor spacings, resulting in low work efficiency. Consequently, the X-ray inspection of multi-split conductors for tension clamps cannot be completed efficiently, increasing manpower and material costs.

[0005] Therefore, how to effectively adapt to the radiographic testing of digital display tension clamps for lines with different line spacings has become an urgent problem to be solved in the field of testing 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 X-ray inspection of tension clamps for multi-split transmission lines, which are incompatible with equipment due to different line spacings at different locations. This invention provides an X-ray inspection system and method for tension clamps of multi-split transmission lines. Through a detachable first wheel mechanism and a second wheel mechanism, the wheel spacing is adjusted according to the actual line spacing of the transmission line on the first and second limiting tracks, thereby effectively adapting to different line spacings of the transmission line. The first and second limiting tracks effectively enhance the overall stability of the supporting frame on the transmission line.

[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 lines includes a support frame, a first limiting rail fixed on one side of the support frame, and a second limiting rail fixed on the other side of the support frame;

[0009] The first limiting track and the second limiting track are symmetrically distributed with the center of gravity of the supporting frame as the center;

[0010] A first wheel mechanism is detachably fixed on the first limiting track, and a second wheel mechanism is detachably fixed on the second limiting track. The first wheel mechanism and the second wheel mechanism are connected sequentially as boundary points to form an enclosed area.

[0011] The support frame is equipped with a liftable ray mechanism and a liftable detection mechanism. The liftable ray mechanism can rotate circumferentially, and the liftable detection mechanism can be horizontally extended or horizontally retracted.

[0012] The lifting trajectory of the liftable ray mechanism and the lifting trajectory of the liftable detection mechanism are both within the vertical area covered by the enclosed area.

[0013] Currently, when performing radiographic testing on tension clamps, there is often a need to temporarily adjust the radiographic testing mechanism to accommodate the location distribution of the tension clamps. Workers carry equipment according to the on-site design parameters. However, because the tension clamps to be tested are in a long-term operational state, the actual line spacing of multi-branch transmission lines on-site differs from the design parameters. If the line spacing of the equipment carried does not match the actual transmission line, external tooling or equipment replacement is required for radiographic testing. This significantly impacts work efficiency, resulting in low inspection efficiency for tension clamps. The inability to promptly inspect tension clamps throughout the power grid leads to higher electrical safety risks.

[0014] Based on this, the present invention sets up a detachable first wheel mechanism and a second wheel mechanism, and adjusts the distance between the first wheel mechanism and the second wheel mechanism by disassembling and reinstalling them, thereby adapting to different transmission line spacings. It also expands the X-ray detection range in space by using a liftable detection mechanism and a liftable X-ray mechanism, thereby effectively improving the accuracy of X-ray detection of tension clamps and avoiding X-ray detection errors caused by the overlap of tension clamps.

[0015] If different tension clamps are encountered at different line spacings on the transmission line during the X-ray inspection process, the first wheel mechanism and the second wheel mechanism in this invention can be disassembled and the spacing can be adjusted on-site on the first limit track and the second limit track. By expanding the first limit track and the second limit track, the adaptability of this invention to on-site adjustment of different line spacings is effectively enhanced.

[0016] The first and second limiting tracks are symmetrically distributed around the center of gravity of the supporting frame, which enables the supporting frame to maintain high stability when adjusting its position on the power transmission line, avoiding safety risks such as tilting. It can also effectively utilize the self-weight of the supporting frame to enhance the overall stability of the invention. When there are unstable factors such as shaking in the power transmission line or external environment, the invention can use its own weight to restore stability, thereby preventing the invention from falling off the power transmission line.

[0017] In actual multi-branch transmission lines, tension clamps and current-carrying clamps exist. Current-carrying clamps have two states: horizontal to the ground (single-circuit middle phase); and vertical to the ground (single-circuit side phase, double-circuit). Therefore, during conventional X-ray inspection, current-carrying clamps can obstruct the X-ray inspection equipment, preventing effective X-ray inspection of the corresponding tension clamps. This invention utilizes a supporting frame as a foundation, effectively accommodating the liftable X-ray mechanism and the liftable detection mechanism between two transmission conductors. That is, the lifting trajectories of both the liftable X-ray mechanism and the liftable detection mechanism are located within the enclosed area. Within the covered vertical area, the position of the X-ray detection area can be adjusted within the vertical area without being obstructed by the drain clamp. Therefore, this invention can eliminate the interference of the drain clamp when performing X-ray detection on the tension clamp. In this process, the liftable X-ray mechanism and the liftable detection mechanism can be combined to form the X-ray detection area. By unfolding the liftable detection mechanism, the X-ray detection area can be constructed within the space formed by its unfoldable stroke range and lifting stroke range. This allows for flexible adjustment of the X-ray detection area within this space and avoids obstruction by obstacles during the adjustment of the X-ray detection area.

[0018] This invention, when using the first and second wheel mechanisms for movement, is not affected by the drainage clamps or branch wires, thus ensuring flexibility in position adjustment and reducing the risk of obstruction when adjusting the position of the radiation detection area. In a preferred embodiment, the liftable detection mechanism is located above the radiation emission port of the liftable radiation mechanism, ensuring that the radiation emission direction is upward, avoiding damage to the ground environment and organisms. Furthermore, the location of the liftable detection mechanism above the radiation emission port of the liftable radiation mechanism allows for more flexible adjustment of the radiation detection area.

[0019] Furthermore, the first wheel mechanism includes a first wheel bracket, which is slidable along the first limiting track and detachably fixedly connected to the first limiting track, and an obstacle-crossing wheel is installed on the first wheel bracket;

[0020] The second wheel mechanism includes a second wheel bracket, which can slide along the second limiting track and is detachably and fixedly connected to the second limiting track. A load-bearing wheel is installed on the second wheel bracket.

[0021] The diameter of the obstacle-crossing wheel is larger than the diameter of the load-bearing wheel.

[0022] 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.

[0023] Furthermore, a locking assembly is fixed to the side of the second wheel bracket, the locking assembly being able to abut against the side of the bearing wheel or disengage from the side of the bearing wheel.

[0024] This invention utilizes a locking component to press down on the side of the bearing wheel or the cable in contact with the bearing wheel, thereby using friction to stop the walking motion. When the friction provided by the locking component is controllable, the friction of the locking component can also be used to maintain the walking motion of the bearing wheel, thereby ensuring the stability of the invention during walking. If encountering a slope, the probability of slipping can be reduced by increasing the friction area.

[0025] Furthermore, the liftable detection mechanism includes a first base platform, on which a detection lifting component is fixed. The upper end of the detection lifting component is fixed to the first base platform, and its lower end is capable of longitudinal extension and retraction and is fixed with a detector.

[0026] The liftable X-ray mechanism includes a second base platform, on which a X-ray lifting component is fixed. The upper end of the X-ray lifting component is fixed to the second base platform, and its lower end is capable of longitudinal extension and retraction and is fixed with an X-ray machine component.

[0027] The second base platform is located below the first base platform and avoids the vertical area of ​​the first base platform.

[0028] 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.

[0029] Furthermore, the detection lifting assembly includes a first winch, which is fixed to the first base platform. A first lifting telescopic frame is provided below the first winch. The upper end of the first lifting telescopic frame is fixed to the first base platform, and the lower end of the first lifting telescopic frame can slide and extend longitudinally. The detector is fixed to the bottom of the first lifting telescopic frame.

[0030] 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 second lifting telescopic frame can slide and extend longitudinally. The X-ray machine assembly is fixed to the bottom of the second lifting telescopic frame.

[0031] The first and second lifting telescopic frames have the same structure.

[0032] 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.

[0033] 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.

[0034] 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.

[0035] Furthermore, the detector includes a first lifting end head, which is fixed to the first lifting telescopic frame. A transverse telescopic frame is fixed on the first lifting end head. One end of the transverse telescopic frame is fixed to the first lifting end head, and the other end can be extended or retracted laterally. A detection connection end head is fixed on the transverse telescopic frame, and the detection connection end head can reciprocate with the transverse telescopic frame.

[0036] The probe connection end is fixed with a plate mounting frame, and the probe plate is mounted on the plate mounting frame.

[0037] 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.

[0038] Furthermore, the X-ray machine assembly includes a X-ray platform, which is fixed to the second lifting and telescopic frame;

[0039] A radiation mounting frame is fixed on the radiation platform, and a radiation machine body is rotatably connected inside the radiation mounting frame. A rotating motor is installed on the radiation mounting frame and connected to the end of the radiation machine body.

[0040] The side of the radiation mounting frame is provided with a stabilizing reinforcing plate. One side of the stabilizing reinforcing plate is fixed to the radiation mounting frame, and the other side is fixed to the radiation platform.

[0041] 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.

[0042] 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.

[0043] Furthermore, the first lifting telescopic frame includes a platform connecting frame, which is fixed to the first base platform. A lifting frame is fixed below the platform connecting frame, and a sliding frame assembly is provided inside the lifting frame. The upper end of the sliding frame assembly is fixed to the lifting frame, and its lower end can extend and retract longitudinally.

[0044] A connecting seat is fixed at the bottom of the sliding frame assembly. Several fixed frames are fixed on the connecting seat. Each fixed frame is equipped with a lifting pulley. The rope of the first winch extends toward the lifting pulley and passes through the lifting pulley. The first winch and the lifting pulley form a movable pulley.

[0045] The platform connecting frame of the second lifting telescopic frame is fixed to the second base platform, and the second winch and the lifting pulley of the second lifting telescopic frame form a movable pulley.

[0046] 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.

[0047] 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.

[0048] 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.

[0049] 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.

[0050] 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.

[0051] Furthermore, the lifting frame is provided with several transverse reinforcing ribs, which circumferentially surround the lifting frame.

[0052] The sliding frame assembly includes a first sliding frame and several second sliding frames, wherein the second sliding frames are sleeved on the first sliding frame and slidably connected to the first sliding frame;

[0053] Several second sliding frames are sequentially fitted onto adjacent second sliding frames, and two adjacent second sliding frames are slidably connected.

[0054] The outer side of the sliding frame assembly is fixed to the lifting frame.

[0055] 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.

[0056] An X-ray inspection method for tension clamps in multi-split transmission lines includes the following steps:

[0057] Adjust the wheel spacing of the first wheel mechanism and the wheel spacing of the second wheel mechanism according to the line spacing of the transmission line to be tested;

[0058] Connect the drone to the drone mount and use the drone to transport the X-ray inspection system of the tension clamp of the multi-split transmission line to the top of the multi-split transmission line to be inspected.

[0059] The position of the drone was adjusted so that both the first wheel mechanism and the second wheel mechanism were mounted on the power transmission line;

[0060] Adjust the height of the liftable ray mechanism and the liftable detection mechanism within the support frame to correspond to the tension clamp to be tested: when the liftable ray mechanism is aligned with the tension clamp to be tested, the ray can irradiate the tension clamp to be tested and image it in the liftable detection mechanism;

[0061] Acquire an image formed on the liftable detection mechanism by the tension wire clamp;

[0062] Determine whether the image is qualified. If it is not qualified, readjust the liftable ray mechanism and the liftable detection mechanism and emit the ray again.

[0063] Currently, existing technologies for X-ray inspection of tension clamps typically employ single-position imaging, which can yield inaccurate results. Therefore, this invention utilizes a first wheel mechanism and a second wheel mechanism to stably mount the liftable X-ray mechanism and the liftable detection mechanism, effectively increasing the detectable angle of the tension clamp under inspection. The liftable X-ray mechanism and the liftable detection mechanism adjust the position of the X-ray inspection area, ensuring that the X-ray inspection is conducted in an environment with reduced interference. If the image is deemed acceptable, the X-ray image is effectively analyzed to protect the accuracy of the X-ray inspection. If the image is deemed unacceptable, a new angle is adjusted for re-inspection, thus ensuring the accuracy and effectiveness of the X-ray inspection results.

[0064] In summary, the present invention has the following advantages compared with the prior art:

[0065] When the invention utilizes the first and second wheel mechanisms for movement, it is unaffected by the drainage clamps or branch wires, thus ensuring flexibility in position adjustment and reducing the risk of obstruction when adjusting the position of the radiation detection area. In a preferred embodiment, the liftable detection mechanism is located above the radiation emission port of the liftable radiation mechanism, ensuring that the radiation emission direction is upward, avoiding damage to the ground environment and organisms. Furthermore, the location of the liftable detection mechanism above the radiation emission port of the liftable radiation mechanism also allows for more flexible adjustment of the radiation detection area.

[0074] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the embodiments and accompanying drawings. The illustrative embodiments and descriptions of this invention are only for explaining this invention and are not intended to limit this invention. Example

[0075] like Figures 1-5As shown, this embodiment relates to an X-ray inspection system for tension clamps of multi-split transmission lines, including a support frame 3, a first limiting rail 4 fixed on one side of the support frame 3, and a second limiting rail 12 fixed on the other side of the support frame 3.

[0076] The first limiting track 4 and the second limiting track 12 are symmetrically distributed with the center of gravity of the supporting frame 3 as the center;

[0077] A first wheel mechanism is detachably fixed on the first limiting track 4, and a second wheel mechanism is detachably fixed on the second limiting track 12. The first wheel mechanism and the second wheel mechanism are connected sequentially as boundary points to form an enclosed area.

[0078] The support frame 3 is equipped with a liftable ray mechanism and a liftable detection mechanism. The liftable ray mechanism can rotate circumferentially, and the liftable detection mechanism can be horizontally extended or horizontally retracted.

[0079] The lifting trajectory of the liftable ray mechanism and the lifting trajectory of the liftable detection mechanism are both within the vertical area covered by the enclosed area.

[0080] In practical application, the supporting frame 3 serves as the main supporting body and the basis for area delineation. The first wheel mechanism and the second wheel mechanism are used as boundary points to form an enclosed area. Under the restriction of the first limiting track 4 and the second limiting track 12, the enclosed area can be limited to the two power transmission lines connected by the first wheel mechanism and the second wheel mechanism. Thus, in the overall operation of this embodiment, the liftable detection mechanism and the liftable ray mechanism can be accommodated in the space between the two power transmission lines. During this process, obstacles on the power transmission lines will not affect the positional changes of this embodiment.

[0081] Based on this, if the liftable detection mechanism needs to be deployed, the combination of the lifting trajectory and the deployment trajectory can avoid obstruction by obstacles, thus enabling this embodiment to more flexibly adjust the X-ray detection area to the required range. The accuracy of X-ray detection is effectively improved, and the pass rate of X-ray detection imaging is also effectively improved.

[0082] Furthermore, the first wheel mechanism includes a first wheel bracket 5, which can slide along the first limiting track 4 and is detachably and fixedly connected to the first limiting track 4. An obstacle-crossing wheel 6 is installed on the first wheel bracket 5.

[0083] The second wheel mechanism includes a second wheel bracket 11, which can slide along the second limiting rail 12 and is detachably and fixedly connected to the second limiting rail 12. A load-bearing wheel 10 is installed on the second wheel bracket 11.

[0084] The diameter of the obstacle-crossing wheel 6 is larger than the diameter of the load-bearing wheel 10.

[0085] Furthermore, a locking component 9 is fixed to the side of the second wheel bracket 11, the locking component 9 being able to abut against the side of the bearing wheel 10 or disengage from the side of the bearing wheel 10.

[0086] 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.

[0087] In this embodiment, both the first limiting rail 4 and the second limiting rail 12 are provided with several sets of mounting holes. The detachable fixing method in this embodiment is fastener fixing connection. By changing the installation position of the first wheel bracket 5 and / or the second wheel bracket 11 on the first limiting rail 4 and / or the second limiting rail 12, the spacing between the first wheel brackets 5 and the spacing between the second wheel brackets 11 can be changed, thereby enabling this embodiment to adapt to different power transmission conductor spacings.

[0088] 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.

[0089] In this embodiment, both the obstacle-crossing wheel 6 and the load-bearing wheel 10 are equipped with brushless DC motors and driven in conjunction with planetary reducers, enabling this embodiment to travel on the power transmission line, thereby changing its position on the power transmission line and achieving the purpose of performing X-ray inspection on tension clamps at different positions.

[0090] 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.

[0091] Furthermore, the liftable detection mechanism includes a first base platform 17, on which a detection lifting component 1 is fixed. The upper end of the detection lifting component 1 is fixed to the first base platform 17, and its lower end can extend and retract longitudinally and is fixed with a detector 7.

[0092] The liftable X-ray mechanism includes a second base platform 14, on which a X-ray lifting assembly 13 is fixed. The upper end of the X-ray lifting assembly 13 is fixed to the second base platform 14, and its lower end can extend and retract longitudinally and is fixed with an X-ray machine assembly 8.

[0093] The second base platform 14 is located below the first base platform 17 and avoids the vertical area of ​​the first base platform 17.

[0094] Both the first base platform 17 and the second base platform 14 are support 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 X-ray lifting component 13. The limiting ends 15 on the first base platform 17 and the second base platform 14 can be enhanced in stability by adding reinforcing crossbars 16, thereby reducing the probability of instability occurring in the first base platform 17 and the second base platform 14 during use.

[0095] Furthermore, the detection lifting assembly 1 includes a first winch 101, which is fixed to 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 the lower end of the first lifting telescopic frame 18 can slide and extend longitudinally. The detector 7 is fixed to the bottom of the first lifting telescopic frame 18.

[0096] 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 second lifting telescopic frame 132 can slide and extend longitudinally. The X-ray machine assembly 8 is fixed to the bottom of the second lifting telescopic frame 132.

[0097] The first lifting telescopic frame 18 and the second lifting telescopic frame 132 have the same structure.

[0098] 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.

[0099] 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.

[0100] 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.

[0101] 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.

[0102] Furthermore, the detector 7 includes a first lifting end 74, which is fixed to the first lifting telescopic frame 18. A transverse telescopic frame 75 is fixed on the first lifting end 74. One end of the transverse telescopic frame 75 is fixed to the first lifting end 74, and the other end can be extended or retracted laterally. A detection connection end 71 is fixed on the transverse telescopic frame 75, and the detection connection end 71 can reciprocate with the transverse telescopic frame 75.

[0103] The detection connection end 71 is fixed with a plate mounting frame 73, and the detection plate 72 is installed on the plate mounting frame 73.

[0104] Furthermore, the X-ray machine assembly 8 includes a X-ray platform 83, which is fixed to the second lifting telescopic frame 132;

[0105] A radiation mounting frame 81 is fixed on the radiation platform 83. A radiation machine body 84 is rotatably connected inside the radiation mounting frame 81. A rotating motor 85 is installed on the radiation mounting frame 81 and is connected to the end of the radiation machine body 84.

[0106] The side of the radiation mounting frame 81 is provided with a stabilizing reinforcing plate 82. 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.

[0107] 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.

[0108] 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 body 84. The rotation drive of the X-ray machine body 84 is realized by the rotation motor 85 installed on the X-ray mounting frame 81, thereby changing the X-ray emission direction of the X-ray machine body 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.

[0109] 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.

[0110] Furthermore, the first lifting telescopic frame 18 includes a platform connecting frame 181, which is fixed to the first base platform 17. A lifting frame 182 is fixed below the platform connecting frame 181. A sliding frame assembly is provided inside the lifting frame 182. The upper end of the sliding frame assembly is fixed to the lifting frame 182, and its lower end can extend and retract longitudinally.

[0111] A connecting seat 188 is fixed at the bottom of the sliding frame assembly. Several fixing frames 187 are fixed on the connecting seat 188. Each fixing frame 187 is equipped with a lifting pulley 186. The rope of the first winch 101 extends toward the lifting pulley 186 and passes through the lifting pulley 186. The first winch 101 and the lifting pulley 186 form a movable pulley.

[0112] The platform connecting frame 181 of the second lifting telescopic frame 132 is fixed to the second base platform 14, and the second winch 131 and the lifting pulley 186 of the second lifting telescopic frame 132 form a movable pulley.

[0113] Furthermore, the lifting frame 182 is provided with a plurality of transverse reinforcing ribs 183, which circumferentially surround the lifting frame 182.

[0114] The sliding frame assembly includes a first sliding frame 184 and a plurality of second sliding frames 185, wherein the second sliding frames 185 are sleeved on the first sliding frame 184 and slidably connected to the first sliding frame 184.

[0115] Several second sliding frames 185 are sequentially sleeved on the outside of adjacent second sliding frames 185, and two adjacent second sliding frames 185 are slidably connected;

[0116] The outer side of the sliding frame assembly is fixed to the lifting frame 182.

[0117] 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.

[0118] 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.

[0119] 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.

[0120] 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.

[0121] 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.

[0122] 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. Example

[0123] like Figure 6 As shown, this embodiment relates to an X-ray inspection method for tension clamps in multi-split transmission lines, including the following steps:

[0124] Adjust the wheel spacing of the first wheel mechanism and the wheel spacing of the second wheel mechanism according to the line spacing of the transmission line to be tested;

[0125] Connect the drone to the drone mount 2, and use the drone to transport the X-ray inspection system of the tension clamp of the multi-split transmission line described in Example 1 to the multi-split transmission line to be inspected.

[0126] The position of the drone was adjusted so that both the first wheel mechanism and the second wheel mechanism were mounted on the power transmission line;

[0127] Adjust the height of the liftable ray mechanism and the liftable detection mechanism inside the support frame 3 to correspond to the tension clamp to be tested: when the liftable ray mechanism is aligned with the tension clamp to be tested, the ray can irradiate the tension clamp to be tested and image it in the liftable detection mechanism;

[0128] Acquire an image formed on the liftable detection mechanism by the tension wire clamp;

[0129] Determine whether the image is qualified. If it is not qualified, readjust the liftable ray mechanism and the liftable detection mechanism and emit the ray again.

[0130] In this embodiment, the first wheel mechanism and the second wheel mechanism can stably mount the liftable X-ray mechanism and the liftable detection mechanism, thereby effectively increasing the detectable angle of the tension clamp to be tested. The liftable X-ray mechanism and the liftable detection mechanism adjust the position of the X-ray detection area, thereby ensuring that the X-ray detection is obtained in an environment with reduced interference. After the image is judged to be qualified, the X-ray image is effectively analyzed, thereby protecting the accuracy of the X-ray detection. If the image is judged to be unqualified, a new angle is adjusted for re-detection, thereby ensuring the accuracy and effectiveness of the X-ray detection results.

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.
