[0002] With the continuous progress of China's economy and society, the power supply and consumption continue to rise, and it is particularly important to ensure the safety and reliability of power supply. The establishment, upgrading and cable maintenance of the power transmission tower are more important. At present, the installation, upgrading and cable maintenance of the power tower need to be operated manually. In the process of upgrading and cable maintenance, the workers need to work on the anti-falling device in the air. In order to ensure the safety of the workers, they need to wear anti-falling devices. The anti-falling device is connected with the anti-falling device, and the anti-falling device can move along the anti-falling device.

[0003] The existing anti-falling device can only move along the horizontal or vertical direction of the anti-falling device. If the direction needs to be changed, the reversing device needs to be used to convert the anti-falling device from the horizontal direction to the vertical direction, or from the vertical direction to the horizontal direction. In actual application, the workers often need to move between the inside and outside of the anti-falling device. If the traditional reversing device is used, the inside and outside cannot be converted, and the workers need to release the anti-falling device and move it again. This process not only increases the safety hazard of the workers, but also has poor continuity and low work efficiency. SUMMARY

[0029] like Figure 1 , 2 As shown in Figure 3, Figure 1 This is a three-dimensional structural diagram of the commutator in the embodiment; Figure 2 This is another three-dimensional structural diagram of the commutator in the embodiment;Figure 3 It is a perspective view of the fixing member 1 in the embodiment. The commutator in the embodiment includes the fixing member 1 and the rotating core 2, the rotating core 2 is rotationally connected to the fixing member 1, and the rotating core 2 can rotate relative to the rotating core 2.

[0030] The fixing member 1 is provided with a receiving groove 11, and the rotating core 2 is arranged in the receiving groove 11 and can rotate in the receiving groove 11. In specific application, the fixing member 1 is provided with a connecting groove 12, which is spliced with a track on the anti-falling device. Specifically, the fixing member 1 is also provided with a connecting hole 13, which is in communication with the connecting groove 12. The track on the anti-falling device and the connecting groove 12 are mutually sleeved, and then a bolt is inserted into the connecting hole 13 to splice the two. In the embodiment, the fixing member 1 is in a strip shape, both ends of which are provided with the connecting groove 12. The groove opening of the connecting groove 12 is located in the length direction of the fixing member 1. The connecting hole 13 is arranged on the two outer wall surfaces opposite to each other of the connecting groove 12. After the bolt passes through the connecting hole 13 and the connecting groove 12, it is threaded out from the connecting hole 13 on the other side, and is fixed by screwing a nut. The receiving groove 11 is located in the middle of the fixing member 1.

[0031] Preferably, two protrusions 14 are arranged side by side along the length direction of the fixing member 1, and the two protrusions 14 are located in the extension direction of the inner wall of the receiving groove 11. The rotating core 2 is rotationally arranged on the protrusions 14. Since the protrusions 14 protrude from the surface of the fixing member 1, the rotating core 2 is convenient to install, disassemble and maintain.

[0032] Please refer to Figure 4 together, Figure 4 It is a perspective view of the combination member 3 in the embodiment. Further preferably, the commutator further includes the combination member 3, which rotationally connects the fixing member 1 and the rotating core 2. The combination member 3 has a fixed area 31 and a rotating area 32. One end of the combination member 3 passes through the protrusion 14 and is inserted into the rotating core 2. The fixed area 31 is inserted into the rotating core 2 to make the two into one. The rotating area 32 is located in the protrusion 14, and the rotating area 32 can rotate relative to the protrusion 14. Specifically, the number of the combination member 3 is two, and the two combination members 3 are arranged on the two protrusions 14, respectively.

[0033] Please refer to Figure 5 and Figure 6 together, Figure 5 It is a perspective view of the rotating core 2 in the embodiment; Figure 6Another perspective view of the rotating core 2 in the embodiment. The rotating core 2 comprises a connecting piece 21, a rotating piece 22 and a limiting piece 23. One end of the connecting piece 21 is connected with the rotating piece 22, and the other end of the connecting piece 21 is adapted to the arresting device, that is, the arresting device is connected with the end of the connecting piece 21 away from the rotating piece 22. The limiting piece 23 is arranged on the rotating piece 22. The rotating piece 22 is provided with a rotating hole 221, and the fixed area 31 of the combination piece 3 is inserted into the rotating hole 221. The connecting piece 21, the rotating piece 22 and the limiting piece 23 all rotate around the rotating hole 221. Preferably, the rotating piece 22 is provided with rotating holes 221 at both ends, and the two rotating holes 221 are connected with the two combination pieces 3. The two rotating holes 221 can increase the stability during rotation. Further preferably, the rotating hole 221 is further provided with a thread 211, and the thread 211 is adapted to the fixed area 31 of the combination piece 3, so as to improve the stability of the connection between the combination piece 3 and the rotating piece. In another embodiment, the shape of the rotating piece 22 is a cylinder, and the rotating holes 221 are provided at both ends of the cylinder.

[0034] In a specific application, the shape of the end of the connecting piece 21 away from the rotating piece 22 is adapted to the track of the arresting device, and the arresting device on the staff can move on the track of the arresting device and the connecting piece 21.

[0035] The limiting piece 23 comprises a limiting sheet 231 and a limiting block 232. The limiting sheet 231 is arranged on the rotating piece 22, and the limiting block 232 is arranged on the limiting sheet 231. Preferably, the number of the limiting sheets 231 is two, and the two limiting sheets 231 are arranged on the rotating piece 22 at intervals. Correspondingly, the number of the limiting blocks 232 is also two, and the two limiting blocks 232 are arranged on the two limiting sheets 231, respectively. The limiting blocks 232 abut against the arresting device to limit the rotation, and therefore, the positions of the two limiting blocks 232 will determine the angle of the rotation of the connecting piece 21. Further preferably, the limiting sheet 231 has a first end 2311 and a second end 2312, and the first end 2311 and the second end 2312 are located on the same horizontal line. One limiting block 232 is arranged on the first end 2311 of one limiting sheet 231, and the other limiting block 232 is arranged on the second end 2312 of the other limiting sheet 231. The two limiting blocks 232 are arranged on the sides of the two limiting sheets 231 away from each other. In this way, when the connecting piece 21, the rotating piece 22 and the limiting piece 23 are rotated forward by 180°, one limiting block 232 will abut against the side wall of the fixed piece 1 to stop, and it will not be able to continue to rotate in the same direction. Similarly, when the connecting piece 21, the rotating piece 22 and the limiting piece 23 are rotated reversely by 180°, the other limiting block 232 will abut against the side wall of the fixed piece 1 to stop. Specifically, the cross section of the limiting sheet 231 is an arc structure, and the shape of the limiting block 232 is a cylinder. The limiting block 232 is arranged on the side of the limiting sheet 231 away from the other limiting sheet 231.

[0036] Preferably, the rotating core 2 further comprises a reinforcing piece 24 connected with the limiting pieces 231. In specific applications, the reinforcing piece 24 comprises a first reinforcing plate 241 and a second reinforcing plate 242, the first reinforcing plate 241 is located between the two limiting pieces 231, and the two ends of the first reinforcing plate 241 are connected with the two limiting pieces 231 respectively, and the second reinforcing plate 242 is arranged on the first reinforcing plate 241, and the second reinforcing plate 242 is connected with the limiting pieces 231. Through the arrangement of the first reinforcing plate 241 and the second reinforcing plate 242, the stability of the structure of the limiting piece 231 is reinforced, and damage caused by the impact force generated by the abutting collision between the limiting block 232 and the anti-falling device during use is prevented, and the service life is prolonged. Specifically, the number of the second reinforcing plate 242 is multiple, and the multiple second reinforcing plates 242 are arranged on the opposite sides of the first reinforcing plate 241 respectively, the contact area between the second reinforcing plate 242 and the limiting piece 231 is increased, the structure of the limiting piece 231 is further reinforced, and the limiting piece 231 is not easy to be damaged during use.

[0037] In use, the two accommodating grooves 11 of the fixing piece 1 are respectively spliced with the tracks of the anti-falling device, then the two are fixed through bolts, and then the rotating core 2 is rotatably connected with the fixing piece 1 through the connecting piece 3. When the worker moves to this place, the rotating hole 221 can be used as the center to rotate 180°, and after rotation, the limiting block 232 abuts against the fixing piece 1 to limit, at this time, the worker can turn from one side of the anti-falling device to the other side to continue working.

[0038] In summary, through the cooperation of the fixing piece and the rotating core, the rotating hole on the rotating piece is used as the rotation center, the connecting piece and the limiting piece are rotated relative to the fixing piece, the limiting piece abuts against the fixing piece to limit after being rotated to the specified position, the rotation of the connecting piece is changed, and then the anti-falling device connected with the connecting piece also changes direction, and changes from the inside to the outside, or changes from the outside to the inside. The whole process does not need to touch the anti-falling device, the safety of the worker is ensured, at the same time, the whole process is good in continuity, and the work efficiency is improved.
