Description

Technical Field

[0001] The present invention relates to the technical field of safety rope delivery and recovery, and in particular to a transmission tower safety rope delivery device and delivery and recovery method based on an unmanned aerial vehicle. Background Art

[0002] Transmission line construction workers generally use hanging safety ropes for fall protection. In order to solve the problem of the first and last tower climbers needing to carry safety ropes, resulting in blind spots in protection, drones are commonly used to drop and retrieve safety ropes.

[0003] The existing drone-based safety rope delivery device, on the one hand, is prone to rope jamming during the delivery process, affecting the delivery efficiency; on the other hand, in order to achieve self-locking fixation of the delivery end of the safety rope (the end connected to the delivery device), the delivery process usually needs to be flipped based on a certain plane. This delivery method is only applicable to some angle steel structures, and is completely unsuitable for pole towers, special-shaped towers or angle steel towers with inclined upper surfaces.

[0004] In addition, in the process of recovering the safety rope, the drone needs to achieve precise positioning, which places high demands on the drone's operating technology and meteorological conditions, affecting work efficiency. Summary of the invention

[0005] In view of this, one of the objects of the present invention is to provide a transmission tower safety rope delivery device based on a drone, so as to improve the efficiency and reliability of the safety rope delivery, and at the same time, improve the universality of the safety rope delivery; the second object of the present invention is to provide a transmission tower safety rope delivery and recovery method based on a drone, so as to improve the efficiency and convenience of the safety rope delivery and recovery.

[0006] To achieve the above object, the present invention provides the following technical solutions:

[0007] A transmission tower safety rope dropping device based on a drone comprises a drone rack, a driven wheel, a frame and a driving wheel, wherein the driven wheel is mounted on the drone rack, one side of the top end of the frame is flip-hinged with the drone rack, and the other side of the top end of the frame is connected to the drone rack via an electric release pin; the driving wheel is mounted on the frame, and a safety rope is clamped and fixed between the driving wheel and the driven wheel.

[0008] In the process of implementing this solution, when the safety rope is hoisted, the electric release pin is in a closed state, and the safety rope is clamped and fixed between the driven wheel and the driving wheel. When the safety rope is dropped, the release device matching the electric release pin receives a release signal, unlocks the electric release pin, and then releases the flip lock between the frame and the UAV bracket. At this time, the frame can flip downward relative to the UAV bracket, synchronously driving the driving wheel to flip downward, thereby releasing the clamping of the safety rope.

[0009] Furthermore, a motor is installed on the frame, and the driving wheel is installed on the output shaft of the motor.

[0010] Furthermore, one side of the top end of the frame is flip-hinged with the drone rack via a hinge shaft.

[0011] Furthermore, the driven wheel is mounted on the UAV bracket via a wheel axle.

[0012] Furthermore, a safety rope guide groove is provided on the driving wheel to facilitate the release and guidance of the safety rope.

[0013] A method for releasing and recovering a safety rope using the above-mentioned transmission tower safety rope releasing device based on a drone. When releasing the safety rope, the safety rope is installed between the driving wheel and the driven wheel, a counterweight is hung on one end of the safety rope, and an electric release pin is in a closed state, so that the driving wheel and the driven wheel are maintained in a clamped state; when the drone flies above the safety rope releasing position, the motor is started to drive the driving wheel to rotate, so that the end of the safety rope hanging with the counterweight drops to the ground, at this time, the release button of the electric release pin is started, and the closed state of the electric release pin is released through the release device, the driving wheel flips downward, and the rope is separated from the driving wheel under the action of its own weight and hung on the target object. After the two rope ends of the safety rope are fixed on the ground, a double-rope form of safety protection is formed; when recovering the safety rope, a recovery ring is put into any one end of the safety rope on the ground, and the recovery ring is connected to the drone with a soft rope. When the drone ascends, the recovery ring slides along the safety rope. When it flies to the highest point, the recovery ring carries the safety rope up until it is completely separated from the target object and then descends and returns to the ground.

[0014] Technical effects and advantages of the present invention:

[0015] 1. When adopting the launching device of the present application, the driving wheel is flipped open during launching, thereby avoiding the rope jamming phenomenon and being beneficial to improving the launching efficiency; at the same time, the safety rope is overlapped on the target beam and fixed to the ground at both ends, which is equivalent to launching two safety ropes at one time. The double rope method forms a mutual pulling and fixing, omitting the self-locking mechanism of the launching device (i.e., the launching end of the safety rope that needs to be fixed by the launching device), the structure is simpler, the protection reliability is higher, and it is not limited by the material and structure type of the tower, and can be applied to all towers to release the anti-fall safety rope, thereby improving the universality.

[0016] 2. The recovery process is based on the form of recovery ring traction. The traction connection between the safety rope and the drone is established from the initial stage. The recovery process does not require precise positioning of the drone, is less affected by wind direction and wind force, and has a higher tolerance rate for drone operators, effectively improving the efficiency and convenience of recovery.

[0024] In the process of implementing this solution, when the safety rope is hoisted, the electric release pin is in a closed state, and the safety rope is clamped and fixed between the driven wheel and the driving wheel. When the safety rope is dropped, the release device matching the electric release pin receives a release signal, unlocks the electric release pin, and then releases the flip lock between the frame and the UAV bracket.

When the drone rises, the recovery ring slides along the safety rope. When it flies to the highest point, the recovery ring carries the safety rope up until it is completely separated from the target object and then descends and returns to the ground.
