UTILITY MODEL CONTENTS
[0004] The utility model provides a climbing operation anti -falling protection device to solve at least one of the above technical problems.
[0005] The utility model adopts the technical scheme that:

[0007] As preferred, the abutment groove outermost side and safety rope minimum spacing are not less than the maximum diameter of power transmission line. This design can guarantee that the abutment groove and power transmission line can abut smoothly in the process of driving the counterweight to rise by pulling safety rope down, reduces the failure rate of installation, and increases installation efficiency.
[0008] As preferred, the abutment groove surface is equipped with the pressure sensor for inducting pressure, the counterweight is equipped with the controller, the pressure sensor feels the pressure signal and controls the automatic locking mechanism to lock safety rope through the controller. When the worker pulls safety rope and makes the counterweight rise to the abutment of power transmission line and abutment groove, the power transmission line exerts a positive pressure on the pressure sensor, the pressure sensor senses the pressure and controls the automatic locking mechanism to lock the wire body of safety rope in the area of counterweight tightly through the controller, and cooperates with the outer wall of counterweight to fix and lock safety rope, simple and efficient operation, without manual intervention, can realize the automatic fixing of safety rope.
[0009] As preferred, the counterweight has a cuboid shell with a length:width:height=2:1:4, and the automatic locking mechanism is arranged on opposite two largest sides of the cuboid shell. Such design can greatly increase the probability that the side of the counterweight matching the automatic locking mechanism for fixing the safety rope is directly opposite the safety rope, thereby greatly improving the success rate of fixing the safety rope and reducing the operation difficulty.
[0010] As preferred, the automatic locking mechanism comprises first grooves symmetrically arranged on opposite two sides of the counterweight, second grooves arranged on opposite two sides of the counterweight opposite the first grooves, a first locking rod rotatably connected in the first grooves, and a second locking rod rotatably connected in the second grooves. The first locking rod and the second locking rod on the same side are both rotated inward to the first position for holding the safety rope, and are both rotated outward to the second position for releasing the holding of the safety rope. In the initial state, the first locking rod and the second locking rod are in the second position. When the abutting groove abuts against the power transmission line, the controller controls the first locking rod and the second locking rod to rotate from the second position to the first position, thereby completing the locking and fixing of the safety rope. The operation is simple, and the fixing efficiency of the safety rope is significantly improved.
[0011] As preferred, the automatic locking mechanism further comprises a driving motor for driving the first locking rod and the second locking rod to rotate, the driving motor is arranged in the interior of the counterweight, and the driving motor is electrically connected with the controller.

The controller is electrically connected with the driving motor, thereby realizing the precise control of starting and stopping of the driving motor, and further improving the rotation precision of the first locking rod and the second locking rod, and ensuring the locking and fixing effect of the safety rope.
[0012] As preferred, when the first locking rod and the second locking rod are in the first position, the distance between the adjacent ends of the first locking rod and the second locking rod is less than the minimum diameter of the safety rope. Such design can further improve the fixing effect of the safety rope when the first locking rod and the second locking rod are in the first position, prevent the risk of the safety rope falling off, and greatly improve the firmness of the safety rope.
[0013] As preferred, the traction assembly comprises a traction hook arranged at the end of the counterweight and a traction rope, and the traction rope has a first hook for connecting the traction device and a second hook for connecting the traction hook at two ends respectively. The first hook is hung on the lock at the bottom of the unmanned aerial vehicle, and the lock at the bottom of the unmanned aerial vehicle can realize the automatic unhooking function, which will not be described here. The second hook is hung on the traction hook, and the operator can drive the counterweight to move vertically by the traction rope through the operation of the unmanned aerial vehicle. The operation is flexible, the unmanned aerial vehicle technology is mature, the flight height can be flexibly controlled, and various construction environments can be adapted.
[0014] As preferred, the outer end of the first embracing lock rod is provided with an electric telescopic rod, the telescopic end of the electric telescopic rod is provided with a plug rod, and the outer end of the second embracing lock rod is provided with a plug slot matched with the plug rod. When the first embracing lock rod and the second embracing lock rod are rotated from the second position to the first position, the controller controls the electric telescopic rod to extend through an electric signal, so that the plug rod is extended and inserted into the plug slot, the gap between the adjacent ends of the first embracing lock rod and the second embracing lock rod is blocked, the risk of the safety rope falling off is completely eliminated, the fixing firmness of the safety rope is maximally improved, and the personal safety of the worker during the high-altitude operation is ensured.
[0015] Due to the adoption of the above technical scheme, the utility model has the beneficial effects as follows:
[0016] The worker lifts the counterweight above the power transmission line through the traction equipment. During the lifting of the counterweight, the abutment groove is in a downward state. After the counterweight is lifted by the traction equipment to cross the power transmission line, the traction equipment continues to carry the counterweight to cross the power transmission line through the traction assembly, so that the counterweight and the safety rope are located on the two sides of the power transmission line. After that, the traction equipment is separated from the traction assembly, and the counterweight falls under the action of its own gravity. The abutment groove is turned over to a state that the groove opening faces upward. When the counterweight stops swinging and is stable, the groove opening of the abutment groove is in alignment with the power transmission line. The worker lifts the counterweight by pulling the end of the safety rope until the abutment groove abuts against the power transmission line. After the abutment groove and the power transmission line abut against each other, the automatic locking mechanism locks the safety rope on the counterweight, so that the safety rope is firmly fixed on the power transmission line. The process operation is simple, practical, and has high fixing strength of the safety rope, which effectively provides a safe and reliable safety belt fixing point for the worker during the high-altitude operation and protects the personal safety of the worker.
