Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of power system maintenance operations, specifically to a fully automatic climbing insulated crossarm. Background Technology
[0002] When performing maintenance and repairs on power systems, workers must climb utility poles to reach higher elevations to complete necessary repairs and inspections. Due to the lack of effective backup safety measures, accidents such as slipping foot straps or hand slippage can directly lead to serious injuries. Furthermore, operations on utility poles often involve the use and replacement of heavy equipment. To reduce labor intensity and improve efficiency, crossarms on the pole or temporary insulated crossarms are typically used as fulcrums, with pulley systems assisting in hoisting the equipment. However, in actual live-line maintenance scenarios, the crossarms themselves are energized and cannot be directly used as support points.
[0003] While commonly available temporary insulating crossarms can address these issues to some extent, they generally rely on manual installation. This not only increases the workload for workers but also requires installation at a safe distance from live parts, potentially limiting hoisting height and making it difficult to meet actual needs. Typically, the final distance of equipment transport must be completed manually by workers on the poles, significantly increasing physical exertion and reducing work efficiency. Utility Model Content

[0016] Please see Figure 1 , Figure 2 , Figure 3This embodiment provides a fully automatic climbing insulated crossarm, including a holding mechanism 1, a drive wheel assembly 2, and a follower wheel assembly 3.
[0017] Furthermore, the holding mechanism 1 includes a linkage assembly 11 and a holding arm assembly 12.
[0018] Furthermore, the holding arm assembly 12 includes an upper holding arm 121 and a lower holding arm 122. In this embodiment, the upper holding arm 121 and the lower holding arm 122 have the same shape, which mainly reduces the weight of the holding arm assembly 12 and saves costs while maintaining the same structural strength.
[0019] The upper holding arm 121 and the lower holding arm 122 are bolted together and arranged vertically opposite each other, wherein the upper holding arm 121 is located directly above the lower holding arm 122.
[0020] Furthermore, both the upper holding arm 121 and the lower holding arm 122 are L-shaped to hold the utility pole 4.
[0021] Furthermore, the linkage assembly 11 includes a first moving block 111, a second moving block 112, a connecting piece 113, and a transmission rod 114.
[0022] Furthermore, the transmission rod 114 passes through the mounting holes of the first moving block 111 and the second moving block 112, wherein the first moving block 111 and the second moving block 112 are threadedly rotatably connected to the transmission rod 114.
[0023] Furthermore, threaded teeth are provided in the mounting holes of the first moving block 111 and the second moving block 112, and threaded teeth are provided on the outer wall of the transmission rod 114 that match the threaded teeth of the first moving block 111 and the second moving block 112, that is, the first moving block 111 and the second moving block 112 are threadedly rotatably connected to the transmission rod 114.
[0024] Furthermore, when the transmission rod 114 rotates in one direction, the first moving block 111 and the second moving block 112 move towards each other (or away from each other); when the transmission rod 114 rotates in another direction, the first moving block 111 and the second moving block 112 move away from each other (or towards each other).
[0025] The first moving block 111 and the second moving block 112 are both hinged to two connecting pieces 113 at their upper and lower ends. The connecting pieces 113 located on the same side are hinged to the upper holding arm 121 and the lower holding arm 122 through the connecting rod 115.
[0026] Furthermore, the first moving block 111 and the second moving block 112 are each provided with four connecting pieces 113 at their upper and lower ends. The four connecting pieces 113 are hinged end to end to form a rhombus shape.
[0027] Furthermore, under the action of the linkage assembly 11, the opening and closing of the holding mechanism 1 can be realized, which can adapt to utility poles 4 with different diameters.
[0028] Furthermore, the two sets of upper holding arms 121 and lower holding arms 122 are arranged opposite each other in a holding shape. The inner side of the holding arm assembly 12 is provided with two follower wheel assemblies 13 and two drive wheel assemblies 14. The two drive wheel assemblies 14 are arranged vertically opposite each other, and the fixed ends of the two drive wheel assemblies 14 are fixedly connected by a connecting plate 15.
[0029] Furthermore, the two follower wheel assemblies 13 are fixed to the ends of the holding arm assembly 12, and the two drive wheel assemblies 14 are fixed to the middle of the holding arm assembly 12. The two follower wheel assemblies 13 and the set of drive wheel assemblies 14 are arranged at a 120° angle to enhance the stability and strength of the holding.
[0030] Furthermore, the follower wheel assembly 13 serves to support, clamp, and slide, and under the action of the drive wheel assembly 14, the follower wheel assembly 13 moves up and down along the utility pole 4.
[0031] Furthermore, a locking drive source 16 is fixedly connected to the side of the connecting plate 15 near the follower wheel assembly 13, and the end of the transmission rod 114 near the connecting plate 15 passes through the connecting plate 15 and is driven to connect to the output shaft of the locking drive source 16.
[0032] Furthermore, when workers need to hoist equipment to the top or upper part of the utility pole 4, the holding mechanism 1 is placed on the wall of the utility pole 4. At this time, the locking drive source 16 is driven to rotate the transmission rod 114, thereby driving the two sets of upper holding arms 121 and lower holding arms 122 to move towards each other until the drive wheel assembly 14 and follower wheel assembly 13 are tightly attached to the utility pole 4 to achieve the holding effect.
[0033] Furthermore, the drive wheel assembly 14 includes a self-driving wheel 141 and a self-driving wheel housing 142.
[0034] Preferably, the self-driving wheel 141 is a hub motor wheel. A hub motor is a drive method in which an electric motor is directly mounted inside the wheel hub. This design eliminates traditional components such as engines, transmissions, and drive shafts, thereby simplifying the vehicle structure and improving energy efficiency. The hub motor directly drives the wheels, allowing independent control of the speed and torque of each wheel, which provides greater flexibility for the equipment's dynamic control system. The movement of the self-driving wheel can be controlled by a remote control, thus driving the equipment to climb or descend along the utility pole.
[0035] Furthermore, the central axis of the self-driving wheel 141 is located in the groove of the self-driving wheel housing 142, wherein a first elastic element 143 is provided between the central axis of the self-driving wheel 141 and the self-driving wheel housing 142.
[0036] Furthermore, the follower wheel assembly 13 includes a follower wheel 131 and a follower wheel housing 132.
[0037] Furthermore, the central axis of the follower wheel 131 is located in the groove of the follower wheel housing 132, wherein a second elastic element 133 is provided between the central axis of the follower wheel 131 and the follower wheel housing 132.
[0038] Furthermore, both the first elastic element 143 and the second elastic element 133 are locking springs. When the self-driving wheel 141 and the follower wheel 131 are in close contact with the utility pole 4, the first elastic element 143 and the second elastic element 133 are pressed together, thereby providing a suitable holding force so that the device is stably held on the utility pole 4.
[0039] Furthermore, the holding arm assembly 12 also includes a reinforcing plate 123.
[0040] Furthermore, both the upper holding arm 121 and the lower holding arm 122 are hinged with reinforcing plates 123 to enhance the stability of the holding mechanism 1.
[0041] Furthermore, a crossbeam 5 is fixedly connected to the side of the connecting plate 123 away from the drive wheel assembly 14, and a crossbeam hook 51 is fixedly connected to the other end of the crossbeam 5 for hoisting the required equipment.
[0042] Preferably, the material of the crossarm 5 is epoxy fiberglass, which meets the 10KV insulation requirement and improves the safety of operation.
[0043] Furthermore, a manual unlocking ring 6 is fixedly connected to one end of the transmission rod 114 away from the locking drive source 16. When the device is powered off or malfunctions, the device can be manually locked onto or removed from the utility pole 4 by manually operating the manual unlocking ring 6.
[0044] Furthermore, since the utility pole 4 has a certain cone angle, position sensors 7 are also provided at the upper and lower ends of the drive wheel assembly 14 to provide real-time feedback on the gap between the holding mechanism 1 and the utility pole 4, thereby adjusting the holding force.
[0045] Working Principle: The fully automatic climbing insulated crossarm provided by this utility model includes a holding mechanism 1, a drive wheel assembly 2, and a follower wheel assembly 3. The holding mechanism 1 includes a linkage assembly 11 and a holding arm assembly 12. The holding arm assembly 12 includes an upper holding arm 121 and a lower holding arm 122. In this embodiment, the upper holding arm 121 and the lower holding arm 122 have the same shape and are bolted together with the upper holding arm 121 and the lower holding arm 122 facing each other vertically. The upper holding arm 121 is located directly above the lower holding arm 122. The linkage assembly 11 includes a first moving block 111, a second moving block 112, a connecting piece 113, and a transmission rod 114. The transmission rod 114 passes through the mounting holes of the first moving block 111 and the second moving block 112, and is threadedly rotatably connected to the transmission rod 114.
[0046] Specifically, when workers need to hoist equipment to the top or upper part of the utility pole 4, the holding mechanism 1 is placed on the wall of the utility pole 4. At this time, the locking drive source 16 is driven to rotate the transmission rod 114, thereby driving the two sets of upper holding arms 121 and lower holding arms 122 to move towards each other until the drive wheel assembly 14 and follower wheel assembly 13 are tightly attached to the utility pole 4, achieving the holding function. Secondly, the drive wheel assembly 14 is remotely driven to work by the remote controller, thereby driving the equipment to move up or down along the utility pole 4 to reach the designated location.
