[0002] During the process of cable maintenance, it is necessary to use an unmanned aerial vehicle (UAV) to operate for hanging the cable and stopping the machine to ensure the fixation of the cable. Due to the working requirements of the UAV, the UAV needs to briefly stop at the working point of the cable, that is, stop and hang at the designated working point. At this time, it is necessary for the UAV to form a reliable connection with the wire when contacting the wire.

[0003] The existing pressing and locking type wire clamping devices have the following deficiencies:

[0004] The existing devices all require workers to climb to the designated position to fix the cable. However, this fixing method is not only dangerous, but also has a high maintenance cost, is prone to errors, and has low operation efficiency, and cannot fix the cable very well.

Detailed implementation manner

[0020] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0021] Please refer to Figures 1 - 5, an embodiment provided by the present utility model: a press-lock type wire clamping device, including a bin body 1. On both sides of the top of the bin body 1, there are multiple groups of second hinge rods 15. On the top of the bin body 1, there are multiple hinge grooves. The second hinge rods 15 are located inside the hinge grooves for convenient connection. One side of the second hinge rod 15 is hinged with a clamping jaw 13, and the top of the second hinge rod 15 is hinged with a mounting tube 14. Inside the mounting tube 14, a sliding rod 21 is slidably connected. On the outer side of the sliding rod 21, there is a buffer spring 20. The end of the sliding rod 21 extends to the outside of the mounting tube 14 and is hinged with a gear 3. The bottom of the second hinge rod 15 is hinged with a first hinge rod 12. At the bottom of the first hinge rod 12, there is a slider 16. On both sides inside the bin body 1, there are multiple guide rails, and the slider 16 is located inside the guide rails to ensure stability during movement. On both sides of both ends of the bin body 1, there are respectively mounting grooves 4. Inside the mounting grooves 4, there are gears 3. The axis of the gear 3 is connected with the slider 16. On one side inside the mounting groove 4, there is a rack 2, and the rack 2 meshes with the gear 3. At the middle position of the inner bottom of the first hinge rod 12, there is a central vibration rod 5. On the outer side of the central vibration rod 5, there is a spring 10. A lifting moving platform 11 is slidably connected between both sides inside the bin body 1. On the top of the locking tooth 8, there is a circular hole, and the circular hole is adapted to the central vibration rod 5, so that the central vibration rod 5 can pass through the lifting moving platform 11 to press the cable. On one side of the bottom of the lifting moving platform 11, there is a locking tooth 8. At both ends of both sides inside the bin body 1, there are guide plates, and the guide plates are adapted to the locking tooth 8 to ensure stability during the lifting of the locking tooth 8. On one side of the inner bottom of the bin body 1, there is a moving block 19. At the bottom of the bin body 1, there is a slideway, and the moving block 19 is located inside the slideway, so that the moving block 19 can move linearly along the slideway to prevent it from deviating. Inside the moving block 19, there is a wire passing channel 17. On the top of the moving block 19, there is a blocking and limiting piece 9. On one side of the moving block 19, there is a return spring 18. At the middle of both ends of the bin body 1, there are wire winding and unwinding wheels 7. On one side of both ends of the bin body 1, there is a steel cable track 6.

[0022] Working principle: During use, the steel cable is threaded into the inside of the steel cable track 6 and the wire passing channel 17, and both ends are wound around the outside of the wire winding and unwinding wheels 7, and the wire winding and unwinding wheels 7 are controlled by the servo motor at its lower part. When the steel cable is loosened, the moving block 19 and the blocking and limiting piece 9 are pushed by the return spring 18 to move in the direction away from the wire winding and unwinding wheels and reach the limit position. When the steel cable is tightened, due to the angle of the steel cable passing through, the tightened steel cable will move the moving block 19 and the locking tooth 8 in the direction close to the wire winding and unwinding wheels. At this time, the blocking and limiting piece 9 contacts the locking tooth 8 on the lifting moving platform 11 for limiting.

[0023] Install this device on the top of the drone. Before contacting the cable, the jaws 13 are in an open state. After the drone moves below the cable and then rises vertically upward until the lifting platform 11 contacts the cable and is pressed down, the lifting platform 11 drives the slider 16, the first hinge rod 12, and the second hinge rod 15 to move downward when it is pressed down, so that the jaws 13 grasp inward simultaneously. At the same time, when the slider 16 moves, it also drives the gear 3 to move, so that the gear 3 rolls along the rack 2 to ensure the stability during the movement. Then, because the steel cable is in a tensioned state at this time, the locking teeth 8 on the platform contact the blocking and limiting piece 9 and are restricted by the blocking and limiting piece 9 and cannot rebound upward. At this time, the cable is tightly clamped between the central vibration rod 5 and the jaws 13. When the drone finishes working and needs to release the cable, just loosen the steel cable on the wire reel 7, and the blocking and limiting piece will be pushed away from the limiting position by the return spring 18. At this time, the lifting platform 11 will be bounced to the highest position by the spring 10, and the two jaws will also reach the maximum open position accordingly.

[0024] And when the central vibration rod 5 transmits vibration upward, the elastic potential energy of the buffer spring 20 inside the installation pipe 14 can reduce the damage of the fixed parts between the two claws and the shell during detonation.

[0025] The design of the structure where the vibration guide rod is located is also used to protect the wire clamping device when transmitting the vibration from the drone below. It mainly uses the spring to eliminate the vibration in the vertical direction and weaken the energy brought by the vibration.
