[0026] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0027] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0028] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The term "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive with other embodiments.

[0029] Example 1, reference Figures 1 to 7 , is the first embodiment of the present invention, which provides a transmission line maintenance operation device, which includes a support member 100, the support member 100 provides support for employees' operations on the wire, including a center pole 101, a hanging rod 102 arranged on the outer wall of the center pole 101, and a pulley 103 arranged on the outer wall of the hanging rod 102. The center pole 101 is the main connection structure and main support structure of the device. After a rope is tied to the pulley 103 arranged on the hanging rod 102, the pulley 103 mechanism can be used to transfer accessories required for maintenance from the ground to the working point in the air, providing convenience for the operators on the wire; and,

[0030] The hanging member 200 allows the device to be conveniently hung directly on the wire where maintenance is needed, including a connecting rod 201 arranged at the top of the center rod 101, hanging seats 202 arranged at both ends of the connecting rod 201, a moving mechanism 203 arranged inside the hanging seat 202, and a locking mechanism 204 arranged on the top of the moving mechanism 203. The middle part of the connecting rod 201 is connected to the center rod 101, and the hanging seats 202 at both ends of the connecting rod 201 can be conveniently hung directly on the wire. The position of the wire fault may not be accurate, and the staff climbs up to the supporting member. After being on 100, it is necessary to move on the wire to reach the accurate fault location, and multiple faults may occur on one wire, so a moving mechanism 203 is provided in the suspension seat 202, and the device can drive the operator to move on the wire with the help of the moving mechanism 203. When the operator reaches the specific fault location, certain body movements are required during the inspection and maintenance process. At this time, if the moving mechanism 203 is not locked, the moving mechanism 203 will drive the entire device to shake, causing inconvenience to the operator's work, so the moving mechanism 203 needs to be locked to provide a stable operating platform for the operator.

[0031] Specifically, the device is provided with a moving mechanism 203, and the staff can carry the device to climb the tower to the height of the conductor as before, and then use the hanging member 200 to hang the device on the conductor and then step on the supporting member 100, and then use the moving mechanism 203 to move to the conductor fault location. However, when a fault occurs in the middle of the conductor between the two towers, it will consume a lot of physical strength to move from the connection between the tower and the conductor. A soft ladder can be fixed on the bottom of the supporting member 100, and then a drone can be used to drive the device directly to the conductor fault location, and the hanging member 200 can be used to hang the device on the conductor. Then the operator uses the soft ladder to climb directly to the device supporting member 100 on the conductor to start inspection and maintenance, eliminating the process of moving from the tower to the conductor fault location, saving physical strength for the staff.

[0032] Example 2, reference Figures 1 to 7, which is the second embodiment of the present invention. Different from the previous embodiment, a passenger seat 104 is provided below the hanging rod 102. When operating in the air, the operator can sit on the passenger seat 104 to operate. The passenger seat 104 is provided on the outer wall of the central pole 101. A foot support 105 is provided below the passenger seat 104. The operator's feet can step on the foot support 105 to provide further support for it. The foot support 105 is provided on the outer wall of the central pole 101. A tail rope ring 106 is provided at the bottom of the central pole 101. A rope can be tied to the tail rope ring 106 and hung to the ground. When there are multiple faults on a wire, people on the ground can pull the rope to apply tension to the device to assist the device to move on the wire, so as to help the operator move to the correct position for maintenance.

[0033] Furthermore, the suspension seat 202 includes a support 202a, the bottom of which is connected to the connecting rod 201, and a side of the support 202a is provided with an inclined surface 202b. Figure 2 and Figure 6 As shown, the middle part of the support platform 202a is hollow, similar to a frame structure, but there is an opening above the inclined surface 202b, which is a hanging opening for facilitating the device to be hung on the wire k. A receiving groove 202c is provided on the top of the support platform 202a, and the moving mechanism 203 includes a slider 203a arranged inside the receiving groove 202c, and a roller 203b is provided on the side of the slider 203a, and the outer wall of the roller 203b is concave. After the device is hung on the wire through the support platform 202a, the bottom of the roller 203b will contact the wire. The outer wall of the roller 203b is concave to make it fit with the wire, help the entire device to be hung on the wire and facilitate the movement of the entire device on the wire, and a rack 203c is provided on the top of the slider 203a.

[0034] Further, such as Figure 4 As shown, the locking mechanism 204 includes a rotating frame 204a arranged on the top of the support platform 202a, and the rotating frame 204a is rotatably connected to the support platform 202a, and can rotate on the support platform 202a. An elastic member 204b is arranged at the bottom of the rotating frame 204a. Preferably, the elastic member 204b can be a torsion spring, and the end of the elastic member 204b away from the rotating frame 204a is connected to the support platform 202a. The elastic member 204b is in a compressed state. When the entire device is not subjected to external force, the elastic member 204b will keep the rotating frame 204a at the top of the support platform 202a and prevent it from rotating downward, so that the device can be easily hung on the wire.

[0035] Specifically, when the device is hung at the fault location on the conductor, people on the ground can pull the rope to apply tension to the device to assist the device to move on the conductor, so as to help the operator move to the exact position for maintenance. After a rope is tied to the pulley 103 set on the hanging rod 102, the pulley 103 mechanism can be used to transfer the accessories required for maintenance from the ground to the work point in the air, providing convenience for the operators on the conductor.

[0036] Example 3, reference Figures 1 to 7 , which is the third embodiment of the present invention. Different from the previous embodiment, a gear 204d is provided at the bottom of the rotating frame 204a and at the side opposite to the elastic member 204b, and a hook structure 204c is provided at the top of the rotating frame 204a. The gear 204d is meshed with the rack 203c. Figure 5 As shown, the hook structure 204c includes a lifting platform 204c-1, and a sliding rod 204c-2 is arranged on the top of the lifting platform 204c-1. The sliding rod 204c-2 is connected to the rotating frame 204a. A sliding groove matching the sliding rod 204c-2 is opened on the rotating frame 204a. The sliding rod 204c-2 can slide in the sliding groove, and can drive the lifting platform 204c-1 to slide up and down on the rotating frame 204a.

[0037] Furthermore, the inner wall of the lifting platform 204c-1 is provided with a threaded rod 204c-3, the top of the threaded rod 204c-3 is connected to the rotating frame 204a, the bottom of the lifting platform 204c-1 is provided with a hook 204c-4, and the top of the hook 204c-4 is provided with an anti-slip layer 204c-5. Figure 7 As shown, a crossbar is provided at the bottom of the drone, and the device can be hung on the crossbar through the hook 204c-4, so that the drone can drive the device to fly to the faulty part of the wire and place the device downward. The hanging opening at the bottom of the support platform 202a of the device can easily hang the device on the wire. At this time, the operator climbs the soft ladder fixed at the bottom of the device, which will apply a downward force to the device, such as Figure 6 As shown, the roller 203b will receive the support force from the wire, so the roller 203b and the support platform 202a will slide relative to each other, that is, the slider 203a slides upward, driving the rack 203c to slide, and the rack 203c will drive the gear 204d to rotate, so that the rotating frame 204a rotates together, as shown in FIG. Figure 5As shown, the rotation of the rotating frame 204a will drive the curved hook 204c-4 to come under the conductor and seal the hanging opening on the supporting platform 202a to prevent the device from shaking and detaching from the conductor during the climbing process of the operator, thereby reducing safety hazards. When the operator climbs onto the device, he can rotate the threaded rod 204c-3 to drive the lifting platform 204c-1 close to the rotating frame 204a, so that the hook will approach the roller 203b until the hook and the roller 203b tightly clamp the conductor. At this time, the moving mechanism 203 is locked and cannot move on the conductor, preventing the device from swinging and interfering with the staff when they are working.

[0038] Specifically, when the faulty part of the conductor is far from the tower, the device can be driven by a drone to fly to the faulty part of the conductor, and the device can be placed downward and hung on the conductor. The staff climbs the soft ladder fixed at the bottom, and the rotating frame 204a rotates to drive the hook 204c-4 to the bottom of the conductor, and seals the hanging opening on the support 202a to prevent the device from shaking and detaching from the conductor during the climbing process. When the operator climbs onto the device, the threaded rod 204c-3 can be rotated to lock the moving mechanism 203 for inspection and maintenance.

[0039] When the maintenance work is completed and the wire can be evacuated, the threaded rod 204c-3 can be rotated first to move the hook 204c-4 away from the wire, and then climb down. When the staff reaches the ground, since the downward force is no longer applied to the device, the elastic member 204b will drive the rotating frame 204a to rotate upward to the top of the support platform 202a, so that the hanging opening on the side of the support platform 202a is exposed. The drone can fly above the device, hook the hook 204c-4 to lift the device upward, and use the hanging opening on the side of the support platform 202a to keep it away from the wire. The device can be easily removed from the wire, further reducing the physical exertion of the staff.
