Description

Technical Field

[0001] This invention relates to the field of maintenance equipment for multi-split transmission lines, specifically to a multifunctional maintenance platform and method for multi-split transmission lines. Background Technology

[0002] Multi-split transmission lines (such as four-split, six-split, and eight-split lines) are the core carriers of ultra-high voltage / extra-high voltage power grids, and their safe operation depends on regular maintenance. Traditional maintenance methods face the following bottlenecks: First, high-altitude operations are risky, as maintenance must be carried out on conductors tens of meters above the ground, requiring personnel to climb or use pulleys for movement, posing risks of falls and electric shock; Second, coordinated operation of split sub-conductors is difficult, as the spacing between multiple sub-conductors is fixed, and existing platforms cannot simultaneously cover adjacent sub-conductors, leading to frequent traversal and relocation of personnel, increasing the risk of imbalance and loss of control; Third, there are significant limitations on the carrying of tools and equipment, requiring maintenance to carry heavy equipment such as crimping equipment, X-ray flaw detectors, and ultraviolet imagers, while traditional maintenance platforms lack sufficient load-bearing capacity and cannot provide stable position adjustment capabilities.

[0003] Therefore, how to construct a maintenance platform that can accommodate tools while maintaining their position, thereby effectively demonstrating the collaborative effect of maintenance work and improving maintenance efficiency, has become an urgent problem to be solved in the field of maintenance equipment for multi-split transmission lines. Summary of the Invention

[0004] The purpose of this invention is to overcome the shortcomings of existing technologies that require multiple maintenance tools and make it difficult to perform position adjustment operations when maintaining multi-split transmission lines, resulting in low maintenance efficiency. This invention provides a multi-functional maintenance platform and method for multi-split transmission lines. By utilizing the different position adjustment methods of the first and second mounting platforms, the appropriate position adjustment operation can be effectively selected, thereby improving maintenance efficiency.

[0005] The objective of this invention is mainly achieved through the following technical solutions:

[0006] A multi-functional maintenance platform for multi-split transmission lines includes a support frame, within which a first lifting component and a second lifting component are provided, wherein the lifting trajectory of the first lifting component is staggered from that of the second lifting component.

[0007] The first lifting component is provided with a first mounting platform, and the second lifting component is provided with a second mounting platform;

[0008] The first mounting platform can move horizontally on the first lifting component, and the second mounting platform can rotate circumferentially around its own axis for adjustment.

[0009] A first base platform and a second base platform are fixed on the supporting frame, and the second base platform is perpendicular to the first base platform in the vertical direction.

[0010] The first lifting component is fixed on the first base platform, and the second lifting component is fixed on the second base platform;

[0011] A walking mechanism is also fixed on the support frame, which is used to drive the support frame to reciprocate.

[0012] Currently, when carrying out maintenance work on multi-split conductors, fixed-point maintenance is usually adopted. When cross-conductor operations are required, the maintenance equipment needs to be re-laid out to ensure that the maintenance work can be carried out normally, but this will greatly reduce the maintenance efficiency.

[0013] This invention uses a support frame as the basis for positioning and support. Both the first and second mounting platforms can carry maintenance equipment. Centered on the support frame, the height of the first and second mounting platforms is adjusted using the first time component and the second lifting component. The corresponding maintenance equipment is transported to the corresponding maintenance position by utilizing the rotation adjustment capability of the first mounting platform and the horizontal movement capability of the second mounting platform. When selecting the first or second mounting platform, the first or second mounting platform should be selected according to the characteristics required by the maintenance equipment, so as to effectively utilize the maintenance function of the maintenance equipment.

[0014] The first and second base platforms are arranged in a staggered manner, allowing them to operate independently and preventing interference between the maintenance equipment on the first and second platforms. This invention utilizes a walking mechanism to move the load-bearing frame, thereby enhancing the overall positional adjustment capability of the invention.

[0015] The walking mechanism includes a first limiting track and a second limiting track, which are symmetrically distributed on the bearing frame.

[0016] Several first wheel brackets are detachably fixed on the first limiting track, and each first wheel bracket is equipped with a first traveling wheel.

[0017] Several second wheel brackets are detachably fixed on the second limiting track. Each second wheel bracket is equipped with a second travel wheel. A locking component is also installed on the second wheel bracket. The locking component can press against the second travel wheel and stop the second travel wheel.

[0018] This invention allows the first and second traveling wheels to directly contact the power transmission line, enabling them to bear the weight of the support frame and the maintenance equipment. Furthermore, both the first and second limiting rails are located on the sides of the support frame, thus housing the maintenance equipment between two traveling support structures. With the maintenance equipment mounted, the center of gravity of this invention remains within the vertical area covered by the support frame. As long as the first and second traveling wheels are stably resting on the power transmission line, this invention avoids safety risks such as tilting.

[0019] The first limiting track and the second limiting track are symmetrically distributed with the center line of the bottom surface of the bearing frame as the center line. Therefore, the present invention can continuously maintain the balance of the overall equipment during the process of traveling on the power transmission line, providing higher stability for maintenance work.

[0020] Since the maintenance equipment is located within the support frame, the movement and maintenance work of the present invention on the transmission line are not hindered by things such as drain clamps or branch conductors on the transmission line. Furthermore, the flexibility of adjusting the maintenance position is effectively improved by the frame structure within the support frame. Combined with the ability of the first and second traveling wheels to adjust the position of the support frame on the transmission line, the adjustment capability of the maintenance position can be effectively improved, thereby enhancing the flexibility and efficiency of the maintenance work.

[0021] Both the first and second limiting tracks are provided with several sets of detachable fixing positions. Through the detachable fixing of the first and second wheel brackets, different spacings can be selected by changing the fixing positions, thereby adapting to different line spacings. The detachable fixing method in this invention can employ bolt fixing.

[0022] The locking assembly includes a telescopic rod, one end of which is fixed to the second wheel bracket, and the other end of which is provided with a hinged end. A limit frame is fixed to the side of the second wheel bracket, and the limit frame is hinged to the side of the hinged end. The telescopic rod is hinged to the end of the hinged end.

[0023] An arc-shaped rod is fixed to the other end of the hinged end away from the telescopic rod, and the arc-shaped rod bends and extends toward the direction of the second traveling wheel;

[0024] A friction roller is fixed to the end of the arc-shaped rod.

[0025] The telescopic rod is used to push the hinged end to rotate. The limiting frame limits the movement trajectory of the arc-shaped rod to rotate toward the wheel surface of the second driving wheel by limiting the side hinge. The power transmission wire that contacts the wheel surface of the second driving wheel is pressed to complete the braking of the second driving wheel.

[0026] The friction roller comes to a stop by pressing against and squeezing the power transmission line, thereby stopping the movement of the entire invention. By controlling the extension and retraction force of the telescopic rod, the squeezing force on the friction roller can be effectively controlled. When the squeezing force is small, the friction roller can help maintain the stability of the entire invention by rotating.

[0027] Both the first base platform and the second base platform are fixed with a number of limiting ends, and a reinforcing crossbar that spans the first base platform or the second base platform is fixed between every two horizontally adjacent limiting ends.

[0028] The first and second base platforms are reinforced by connecting reinforcing crossbars at the limiting ends, thereby enhancing their load-bearing capacity. This ensures stability during maintenance work and prevents swaying or shaking caused by changes in force during lifting.

[0029] The first 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 is provided with a horizontally expandable or retractable telescopic frame. The first mounting platform is installed on the horizontally expandable telescopic frame.

[0030] The second lifting assembly includes a second winch cable, which is fixed to the second base platform. A second lifting telescopic frame is provided below the second winch cable. The upper end of the second lifting telescopic frame is fixed to the second base platform, and its lower end is connected to the second mounting platform. The maintenance equipment is installed on the second mounting platform.

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

[0032] 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 first mounting platform decreases, and when the first lifting telescopic frame retracts, the height of the first mounting platform increases. At the same time, the lateral telescopic frame can drive the first mounting platform 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 maintenance equipment 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 second mounting platform decreases, and when the second lifting telescopic frame retracts, the height of the second mounting platform 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 first mounting platform and the second mounting platform is the same, making the distance between the maintenance equipment mounted on the first mounting platform and the second mounting platform stable and controllable.

[0035] The first mounting platform 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 mounting connection end head.

[0036] The second mounting platform includes a rotating mounting frame, which is fixed to the mounting connection platform;

[0037] A stabilizing reinforcing plate is provided on the side of the rotating mounting frame. One side of the stabilizing reinforcing plate is fixed to the rotating mounting frame, and the other side is fixed to the mounting connection platform.

[0038] The first lifting end is used to connect the first lifting telescopic frame and the transverse telescopic frame, so that the transverse telescopic frame can obtain sufficient extension space, avoid the movement of the transverse telescopic frame being restricted, and maintain the independence of the transverse telescopic frame and the first lifting telescopic frame. The overlapping connection end is used to connect maintenance equipment.

[0039] Similarly, the second mounting platform and the second lifting telescopic frame can effectively connect to the maintenance equipment and rotate the maintenance equipment to adjust its posture.

[0040] The lateral telescopic frame includes a base track, one side of which is fixed to the connecting platform, and the other side is provided with several sets of sliding track groups. Sliding seats are provided between the base track and the sliding track groups, and between two adjacent sliding track groups. The sliding seats are slidably connected to the base track and / or the sliding track groups.

[0041] It is also provided with a connecting sliding end, and the sliding track assembly near the detection mounting frame is slidably connected to the connecting sliding end, and the connecting sliding end is connected to the outside world;

[0042] One end of the base track is provided with a first power group, and the other end is provided with a second power group. The first power group is used to pull the sliding track group to slide in the direction of the first power group, and the second power group is used to pull the sliding track group to slide in the direction of the second power group.

[0043] The first power unit and the second power unit have the same structure;

[0044] The first power unit includes an adjustment motor, which is fixed to the base track. The adjustment motor is connected to a drive wheel and is used to drive the drive wheel to rotate.

[0045] Each end of the sliding track assembly is provided with a translation pulley, and a traction rope is wound around the drive wheel. The traction rope extends in a serpentine manner, passes through the translation pulleys in sequence, and is fixed to the translation pulley at the end. The drive wheel, the traction rope, and the translation pulleys form a series of connected movable pulleys.

[0046] The basic track is used for basic positioning and is fixed to the connecting platform to maintain the overall stability of the transverse telescopic frame. Based on this, by connecting several sliding track groups, the transverse expansion is achieved by sliding the sliding track groups, thereby adjusting the position of the connecting sliding end. The movement of the connecting sliding end can drive the movement of the first mounting platform, thereby adjusting the position of the maintenance equipment.

[0047] Based on this, the base track and the sliding track group are slidably connected by a sliding seat. Therefore, when the first power group pulls the sliding track group, the sliding track group can drive the sliding seat to slide on the base track in the direction of the first power group, and when the sliding seat slides to the end of the base track, it continues to slide in the same direction to reach its own end restricted position. The same applies to the second power group pulling.

[0048] Using a sliding seat to slide the base rail and / or the sliding rail group can effectively extend the sliding extension stroke of the transverse telescopic frame, thereby enabling the transverse telescopic frame to extend laterally to a greater distance, thus effectively increasing the position range that the detector can adjust.

[0049] The adjusting motor drives the drive wheel to rotate, and the drive wheel tightens or loosens the traction rope. The traction rope is connected to multiple sliding pulleys in a serpentine manner to form multiple series of movable pulleys, so that the position of the sliding track group can be adjusted by using the sliding pulleys as fulcrums. When the drive wheel tightens the traction rope, the operation of the movable pulleys can effectively push several sliding track groups to the ends of adjacent sliding track groups in sequence, thereby forming an unfolded state. If reverse adjustment is required, the second power group can be used to perform a reverse pushing operation.

[0050] Furthermore, the sliding track assembly includes a first translation track and a second translation track, the first translation track and the second translation track are parallel to each other, and a track connecting rod is provided between the first translation track and the second translation track. One end of the track connecting rod is fixed to the first translation track, and the other end is fixed to the second translation track.

[0051] The first translational track is slidably connected to the sliding seat, and the second translational track is slidably connected to the sliding seat or the connecting sliding end;

[0052] The translation pulley includes a base, which is fixed to the end of the sliding track assembly. A horizontal pulley is installed inside the base, and a limiting rod is provided on the side of the horizontal pulley away from the sliding track assembly. The limiting rod is fixed to the base.

[0053] The sliding seat includes a first end and a second end, and a synchronous connecting rod is provided between the first end and the second end. One end of the synchronous connecting rod is fixed to the first end, and the other end is fixed to the second end.

[0054] The first end is slidably connected to the base track or the second translation track, and the second end is slidably connected to the first translation track.

[0055] The first translation track and the second translation track are parallel to each other and are slidably connected on both sides by the two tracks. This allows the sliding connection between the first translation track and the sliding seat, and the sliding connection between the second translation track and the sliding seat or the connecting sliding end to be independent of each other. This avoids the limitation of the sliding stroke of the first translation track and the second translation track when sliding, and can effectively increase the overall unfoldable length of the transverse telescopic frame in this invention, thereby increasing the adjustable position range of the detector.

[0056] The first and second ends of the sliding seat are connected by the synchronous connecting rod, so that the positions of the first and second ends change synchronously. When the transverse telescopic frame expands or contracts, the sliding connection between the first and second ends can be continuous on the basis of mutual independence, thereby increasing the adjustable position range of the first mounting platform while maintaining the stability of the equipment being carried for maintenance.

[0057] 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.

[0058] The first winch is fixedly connected to the platform connecting frame, and 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.

[0059] Several horizontal reinforcing ribs are fixed on the lifting frame, and the horizontal reinforcing ribs circumferentially surround the lifting frame.

[0060] 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.

[0061] 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.

[0062] 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.

[0063] 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.

[0064] 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.

[0065] A multi-functional maintenance method for multi-branch transmission lines includes the following steps:

[0066] The position of the traveling mechanism is adjusted according to the line spacing of the transmission line to be inspected;

[0067] A drone mount is installed on the top of the multi-functional maintenance platform for multi-branch transmission lines. The drone is connected to the drone mount, and the drone is used to transport the multi-functional maintenance platform for multi-branch transmission lines to the top of the multi-branch transmission line to be maintained.

[0068] The position of the drone was adjusted so that the multi-functional maintenance platform for multi-split transmission lines was placed on the transmission line;

[0069] Adjust the positions of the first mounting platform and the second mounting platform within the support frame so that both the first mounting platform and the second mounting platform are aligned with the position to be inspected.

[0070] When performing maintenance work, the present invention first selects the corresponding mounting platform according to the specific maintenance equipment. When the first mounting platform is selected, the maintenance equipment can be transported to any position within the space range. When the second mounting platform is selected, the angle of the maintenance equipment can be rotated. After selecting the mounting platform, the maintenance equipment is transported to the appropriate maintenance position by means of drone hoisting and the position adjustment capability of the first and second mounting platforms.

[0071] In summary, the present invention has the following advantages compared with the prior art:

[0072] Since the maintenance equipment is located within the support frame, the movement and maintenance work of the present invention on the transmission line are not hindered by things such as drain clamps or branch conductors on the transmission line. Furthermore, the flexibility of adjusting the maintenance position is effectively improved by the frame structure within the support frame. Combined with the ability of the first and second traveling wheels to adjust the position of the support frame on the transmission line, the adjustment capability of the maintenance position can be effectively improved, thereby enhancing the flexibility and efficiency of the maintenance work.

[0084] 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.

[0085] Example 1:

[0086] like Figures 1 to 8 As shown, a multi-functional maintenance platform for multi-split transmission lines includes a support frame 3, and a first lifting component 1 and a second lifting component 13 are provided inside the support frame 3. The lifting trajectory of the first lifting component 1 and the lifting trajectory of the second lifting component 13 are staggered.

[0087] The first lifting assembly 1 is provided with a first mounting platform 7, and the second lifting assembly 13 is provided with a second mounting platform 8;

[0088] The first mounting platform 7 can move horizontally on the first lifting component 1, and the second mounting platform 8 can rotate circumferentially around its own axis for adjustment.

[0089] The first base platform 17 and the second base platform 14 are fixed on the support frame 3, and the second base platform 14 avoids the first base platform 17 in the vertical direction.

[0090] The first lifting component 1 is fixed on the first base platform 17, and the second lifting component 13 is fixed on the second base platform 14;

[0091] 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.

[0092] In actual operation, this embodiment adjusts the position of the walking mechanism so that it can be effectively mounted on the power transmission line and support the reciprocating motion of the support frame 3. On this basis, maintenance equipment, such as X-ray machine, detector, robotic arm, maintenance hand and / or de-icer, is installed on the first mounting platform 7 and the second mounting platform 8. The maintenance position is adjusted according to the characteristics of the maintenance equipment and the characteristics of the first mounting platform 7 and the second mounting platform 8.

[0093] The first lifting component 1 controls the height of the first mounting platform 7, and the second lifting component 13 controls the height of the second mounting platform 8. The corresponding maintenance equipment is transported to the corresponding maintenance position by utilizing the rotation adjustment capability of the first mounting platform 7 and the horizontal movement capability of the second mounting platform 8. When selecting the first mounting platform 7 and the second mounting platform 8, the first mounting platform 7 or the second mounting platform 8 should be selected according to the characteristics required by the maintenance equipment, so as to effectively utilize the maintenance function of the maintenance equipment by utilizing the first mounting platform 7 and the second mounting platform 8.

[0094] The walking mechanism includes a first limiting track 4 and a second limiting track 12, which are symmetrically distributed on the bearing frame 3.

[0095] 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 a first driving wheel 6.

[0096] Several second wheel brackets 11 are detachably fixed on the second limiting track 12. Each second wheel bracket 11 is equipped with a second driving wheel 10. A locking component 9 is also installed on the second wheel bracket 11. The locking component 9 can press against the second driving wheel 10 and stop the second driving wheel 10.

[0097] The locking assembly 9 includes a telescopic rod 91, one end of which is fixed to the second wheel bracket, and the other end of which is provided with a hinged end 92. A limit frame 93 is fixed to the side of the second wheel bracket, and the limit frame 93 is hinged to the side of the hinged end 92. The telescopic rod 91 is hinged to the end of the hinged end 92.

[0098] An arc-shaped rod 94 is fixed to the other end of the hinged end 92 away from the telescopic rod 91, and the arc-shaped rod 94 bends and extends toward the second traveling wheel 10;

[0099] A friction roller 95 is fixed to the end of the arc-shaped rod 94.

[0100] Based on the actual situation of the power transmission line, the positions of the first wheel support and the second wheel support in this embodiment are adjusted accordingly. By connecting a drone or a crane or other suspension equipment to the drone mount 2, this embodiment is lifted above the power transmission line. The first travel wheel 6 and the second travel wheel 10 are placed on the power transmission line. With the support of the power transmission line, the maintenance work is carried out effectively. The first travel wheel 6 and the second travel wheel 10 are used to transport the carrying frame 3 to each location to be inspected, thereby realizing the completion of multiple inspections in one hoisting.

[0101] In this embodiment, the first limiting track 4 and the second limiting track 12 are symmetrically distributed with the center line of the bottom surface of the bearing frame 3 as the center line, so that the center of gravity can be controlled in the vertical area of ​​the bearing frame. Therefore, this embodiment can not only use the frame structure of the bearing frame 3 to support the maintenance equipment and increase the movable range of the maintenance equipment, but also ensure the stability of the walking mechanism as a whole during movement.

[0102] When braking is required in this embodiment, the telescopic rod 91 extends, and the hinged end 92 rotates around the limiting frame 93 under the push of the telescopic rod 91, squeezing and pushing the arc-shaped rod 94 to swing towards the wheel surface of the second traveling wheel 10. The arc-shaped rod 94 pushes the friction roller 95 to press the power transmission wire in contact with the wheel surface of the second traveling wheel 10 to achieve frictional braking. The telescopic rod 91 is a pneumatic or hydraulic rod, which pushes the hinged end 92 using pneumatic or hydraulic pressure. Since the end of the hinged end 92 is hinged to the end of the telescopic rod 91, and the side of the hinged end 92 is hinged to the limiting frame 93, the position of the hinged end 92 remains unchanged and rotates around the hinge point between the limiting frame 93 and the hinged end 92. This rotation can push the arc-shaped rod 94 to swing and drive the friction roller 95 to press the power transmission wire in contact with the wheel surface of the second traveling wheel 10, thereby achieving frictional braking. During braking, the stability of the overall braking process can be increased by increasing static friction, and hard contact can be avoided to prevent damage to the cable surface.

[0103] When braking is not required in this embodiment, the friction roller 95 can be used to assist in maintaining stability. For example, when walking on a slope or when it is necessary to step over a tension clamp, the second traveling wheel 10 presses the cable on it, and the friction roller 95 is used to abut the cable below the second traveling wheel 10, thereby achieving bidirectional clamping of the cable. By increasing static friction to resist the effect of gravity, this embodiment is prevented from sliding down the slope, thereby effectively improving the actual climbing ability of this embodiment.

[0104] The improved climbing ability is mainly reflected in the fact that the cable is simultaneously compressed by the two components in two different directions, namely the wheel surface of the second traveling wheel 10 and the surface of the friction roller 95. By relying on the rolling friction in two directions, the cable is continuously clamped during the walking process. This allows for the use of more contact area to increase friction when climbing, making it less likely for the cable to slip on slopes.

[0105] In this embodiment, the first traveling wheel is an obstacle-crossing wheel, and the second traveling wheel 10 is a load-bearing wheel. Both are driven by a brushless DC motor and a planetary reducer, 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.

[0106] 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.

[0107] 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.

[0108] 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 first lifting component 1 and the second lifting component 13.

[0109] The first lifting assembly 1 includes a first winch cable, which is fixed on the first base platform 17. A first lifting telescopic frame 18 is provided below the first winch cable. 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 horizontal telescopic frame 72 that can be horizontally expanded or retracted. The first mounting platform 7 is mounted on the horizontal telescopic frame 72.

[0110] The second lifting assembly 13 includes a second winch cable, which is fixed on the second base platform 14. A second lifting telescopic frame is provided below the second winch cable. The upper end of the second lifting telescopic frame is fixed to the second base platform 14, and its lower end is connected to the second mounting platform 8. The maintenance equipment is installed on the second mounting platform 8.

[0111] The first lifting telescopic frame 18 and the second lifting telescopic frame have the same structure.

[0112] The first mounting platform 7 includes a first lifting end head, which is fixed to the first lifting telescopic frame 18. One end of the transverse telescopic frame 72 is fixed to the first lifting end head, and the other end is fixed to a mounting connection end head.

[0113] The second mounting platform 8 includes a rotating mounting frame, which is fixed on the mounting connection platform 71;

[0114] A stabilizing reinforcing plate is provided on the side of the rotating mounting frame. One side of the stabilizing reinforcing plate is fixed to the rotating mounting frame, and the other side is fixed to the mounting connection platform 71.

[0115] The first cable 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 horizontal telescopic frame 72 to move downward. The maintenance equipment is installed on the horizontal telescopic frame 72, so the maintenance equipment also moves up and down with the horizontal telescopic frame 72. When the first lifting telescopic frame 18 adjusts the height position of the horizontal telescopic frame 72, the horizontal telescopic frame 72 can horizontally move and adjust its own horizontal unfolding position at any position and drive the maintenance equipment to adjust its horizontal position. Therefore, the maintenance equipment can move to all the space range that the first lifting telescopic frame 18 and the horizontal telescopic frame 72 can cover when they are extending and retracting under the combined action of the first lifting telescopic frame 18 and the horizontal telescopic frame 72.

[0116] The second cable is the power source for the extension and retraction of the second lifting telescopic frame. The upper end of the second lifting telescopic frame is fixed to the second base platform 14, and its lower end can extend downwards and drive the second mounting platform 8 to rise and fall. Since the maintenance equipment is installed on the second mounting platform 8, the maintenance equipment can rise and fall with the second lifting telescopic frame. Thus, by simultaneously adjusting the height and rotation angle of the maintenance equipment, or adaptively adjusting the height and horizontal position of the maintenance equipment, obstacles such as overlapping tension clamps, drain clamps, or branch conductors can be avoided, thereby achieving the goal of independently maintaining each position to be maintained as much as possible.

[0117] Both the first and second ropes are rope structures capable of rotating to wind up and release the rope, thereby adjusting the bottom height of the first lifting telescopic frame 18 and / or the bottom height of the second lifting telescopic frame by winding and releasing the rope.

[0118] The transverse telescopic frame 72 includes a base track 724. One side of the base track 724 is fixed to the connecting platform 71, and the other side is provided with several sets of sliding track groups. Sliding seats 721 are provided between the base track 724 and the sliding track groups, and between two adjacent sliding track groups. The sliding seats 721 are slidably connected to the base track 724 and / or the sliding track groups.

[0119] It is also provided with a connecting sliding end 729, and the sliding track assembly near the detection mounting frame is slidably connected to the connecting sliding end 729, and the connecting sliding end 729 is connected to the outside world;

[0120] One end of the base track 724 is provided with a first power group, and the other end is provided with a second power group 7210. The first power group is used to pull the sliding track group to slide in the direction of the first power group, and the second power group 7210 is used to pull the sliding track group to slide in the direction of the second power group 7210.

[0121] The first power unit and the second power unit 7210 have the same structure;

[0122] The first power unit includes an adjustment motor 722, which is fixed to the base track 724. The adjustment motor 722 is connected to a drive wheel 723, and the adjustment motor 722 is used to drive the drive wheel 723 to rotate.

[0123] Each end of the sliding track assembly is provided with a translation pulley 727. A traction rope is wound around the drive wheel 723. The traction rope extends in a serpentine manner, passes through the translation pulley 727 in sequence, and is fixed to the translation pulley 727 at the end. The drive wheel 723, the traction rope, and the translation pulley 727 form a series of connected movable pulleys.

[0124] The sliding track assembly includes a first translation track 725 and a second translation track 726. The first translation track 725 and the second translation track 726 are parallel to each other. A track connecting rod 728 is provided between the first translation track 725 and the second translation track 726. One end of the track connecting rod 728 is fixed to the first translation track 725, and the other end is fixed to the second translation track 726.

[0125] The first translation track 725 is slidably connected to the sliding seat 721, and the second translation track 726 is slidably connected to the sliding seat 721 or the connecting sliding end 729;

[0126] The translation pulley 727 includes a base 7271, which is fixed to the end of the sliding track assembly. A horizontal pulley 7272 is installed inside the base 7271. A limiting rod 7273 is provided on the side of the horizontal pulley 7272 away from the sliding track assembly. The limiting rod 7273 is fixed to the base 7271.

[0127] The sliding seat 721 includes a first end 7211 and a second end 7213. A synchronous connecting rod 7212 is provided between the first end 7211 and the second end 7213. One end of the synchronous connecting rod 7212 is fixed to the first end 7211, and the other end is fixed to the second end 7213.

[0128] The first end 7211 is slidably connected to the base track 724 or the second translation track 726, and the second end 7213 is slidably connected to the first translation track 725.

[0129] In this embodiment, when the lateral telescopic frame 72 needs to be extended in the direction of the first power group, the adjustment motor 722 is turned on, the drive wheel 723 rotates, and the traction rope, when tightened, will sequentially and continuously press the translation pulleys 727 at the ends of each sliding track group, thereby generating a pushing force on the translation pulleys 727. On this basis, the translation pulleys 727 can effectively push the sliding track group to slide on the sliding seat 721 or drive the sliding seat 721 to slide together. When the sliding seat 721 stops at the end of an adjacent sliding track group, the subsequent adjacent sliding track groups will continue to slide until all sliding track groups and the sliding seat 721 are located at the end in the same direction, completing the full deployment.

[0130] When it is necessary to retract or expand the transverse telescopic frame 72 in the direction of the second power group 7210, the adjustment motor 722 of the first power group is turned off, and the adjustment motor 722 of the second power group 7210 is turned on. The entire transverse telescopic frame 72 moves in the opposite direction in the same way, thereby driving the maintenance equipment in the opposite direction and completing the adjustment of the horizontal position of the maintenance equipment.

[0131] If the sliding track group uses a single sliding rail for sliding connection, its sliding stroke is limited and its stability is also poor. In this embodiment, the combination of the first translation rail 725 and the second translation rail 726 can make the sliding on the first translation rail 725 and the sliding on the second translation rail 726 relatively independent, and can utilize the full sliding stroke of the first translation rail 725 and the second translation rail 726. Therefore, in this embodiment, the various sliding actions do not affect each other.

[0132] Based on this, the two adjacent sliding track groups can achieve continuous sliding stroke through the fixed connection of the first translation track 725 and the second translation track 726, thereby making the unfolded length of the transverse telescopic frame 72 in this embodiment longer, and thus making the overall telescopic range of this embodiment larger.

[0133] In this embodiment, when adjusting the sliding track group closest to the base track 724: firstly, the first end 7211 slides on the base track 724. When the first end 7211 slides to the end of the base track 724, the first translation track 725, which is slidably connected to the second end 7213, slides on the second end 7213 and drives the second translation track 726 to slide synchronously. The adjacent sliding seat 721, which is slidably connected to the second translation track 726, moves along with the second translation track 726. When the first translation track 725... When the sliding reaches the second end 7213, it stops sliding. The sliding seat 721 on the second translation track 726 continues to slide to the end of the second translation track 726. The subsequent sliding seats 721 and the sliding track group slide in sequence. The power source for sliding comes from the rotation of the drive wheel 723, which drives the traction rope to exert pressure on the translation pulley 727. This causes the first translation track 725 and its end translation pulley 727 to form a movable pulley with the traction rope. The second translation pulley 727 and its end translation pulley 727 also form a movable pulley.

[0134] In this embodiment, the traction rope in the first power group and the traction rope in the second power group 7210 are independent of each other, thereby avoiding mutual interference between the first power group and the second power group 7210.

[0135] In this embodiment, the base 7271 of the translation pulley 727 is used to support the horizontal pulley 7272. The orientation of the base 7271 is adjusted according to the actual insertion position of the traction rope. The limiting rod 7273 is used to restrict the traction rope on the horizontal pulley 7272, thereby preventing the traction rope from detaching from the horizontal pulley 7272 when the sliding direction changes.

[0136] Furthermore, the first lifting telescopic frame 18 includes a platform connecting frame 21, which is fixedly connected to the first base platform 17. A lifting frame 22 is fixed below the platform connecting frame 21. The lifting frame 22 is provided with several sets of parallel second sliding frames 24. Two adjacent second sliding frames 24 are slidably connected. A first sliding frame 25 is slidably connected inside the second sliding frame 24. A connecting seat 28 is fixed at the bottom of the first sliding frame 25. Several fixing frames 27 are fixed on the connecting seat 28. Each fixing frame 27 is equipped with a lifting pulley 26.

[0137] The first winch is fixedly connected to the platform connecting frame 21. The rope inside the first winch extends toward the lifting pulley 26 and passes through the lifting pulley 26. The first winch and the lifting pulley 26 form a movable pulley.

[0138] Several horizontal reinforcing ribs are fixed on the lifting frame 22, and the horizontal reinforcing ribs circumferentially surround the lifting frame 22.

[0139] In this embodiment, the lifting frame 22 is used to accommodate the second sliding frame 24 and the first sliding frame 25. Since the second sliding frame 24 is parallel to each other and slidably connected, and the first sliding frame 25 is slidably connected to the second sliding frame 24, the first sliding frame 25 can slide downwards by its own weight. When the first sliding frame 25 slides downwards, the movable pulley connection formed by the first winch and the lifting pulley 26 in the first lifting telescopic frame 18 can pull back the downward sliding tendency of the first sliding frame 25. Therefore, the first sliding frame 25 requires the first winch to extend its rope. The cable can slide downwards, and when the first sliding frame 25 slides to the bottom end that is slidably connected to the second sliding frame 24, the second sliding frame 24 can be driven to slide downwards in sequence, thereby unfolding a longer telescopic length, so that the first sliding frame 25 can descend to a lower position. Since the connecting seat 28 is fixedly connected to the first sliding frame 25, the height of the maintenance equipment is determined by the height of the first sliding frame 25, which is determined by the length of the rope released by the first cable. The extension length of the second sliding frame 24 limits the limit range that the maintenance equipment can reach.

[0140] In this embodiment, the extension length of the first lifting telescopic frame 18 and the second lifting telescopic frame is increased by the fact that two adjacent second sliding frame bodies 24 can form a longer connecting body by being misaligned on the basis of a sliding connection. Similarly, the first sliding frame body 25 and the second sliding frame body 24 can also form a longer connecting body by sliding misalignment. Therefore, the first sliding frame body 25 and the second sliding frame body 24 can be extended to a longer length range by sliding misalignment.

[0141] The height position of the first sliding frame 25 inside the second lifting telescopic frame is determined by the length of the rope released by the second winch.

[0144] The position of the traveling mechanism is adjusted according to the line spacing of the transmission line to be inspected;

[0145] A drone mount 2 is set on the top of the multi-functional maintenance platform for multi-branch transmission lines. The drone is connected to the drone mount 2, and the drone is used to transport the multi-functional maintenance platform for multi-branch transmission lines to the top of the multi-branch transmission line to be maintained.

[0146] The position of the drone was adjusted so that the multi-functional maintenance platform for multi-split transmission lines was placed on the transmission line;

[0147] Adjust the positions of the first mounting platform 7 and the second mounting platform 8 within the support frame 3 so that both the first mounting platform 7 and the second mounting platform 8 are aligned with the position to be inspected.

When the first mounting platform 7 is selected, the maintenance equipment can be transported to any position within the space.
