Description

Technical Field

[0001] The present invention relates to the technical field of power inspection, and particularly relates to a device for disassembling and assembling a traction rope of a live working lift based on a drone platform. Background Art

[0002] The unmanned aerial vehicle, abbreviated as "drone", is an unpiloted aircraft controlled by a radio remote control device and a self - contained program control device, or is completely or intermittently autonomously operated by an on - board computer. Drones can be divided into military and civilian according to their application fields. In the military aspect, drones are divided into reconnaissance aircraft and target drones. In the civilian aspect, the combination of drones and industry applications is the real demand for drones; their applications in fields such as aerial photography, agriculture, plant protection, micro - self - shooting, express delivery, disaster relief, wildlife observation, infectious disease monitoring, mapping, news reporting, power inspection, disaster relief, film and television shooting, creating romance, etc. have greatly expanded the uses of drones themselves.

[0003] In fields such as power inspection, by directly controlling the drone and the hanging and disassembling device through the drone's remote control, conventional insulation traction rope throwing and hanging can be completed to facilitate subsequent tower climbing operations. The Chinese utility model patent with the application number 202223222079.1 discloses a drone hanging pulley with a flip - type seal, which includes a middle column, a cross beam, a seal door mounting frame, a rope wheel, a seal door, and a hanging ring. The seal door is composed of a sealing arm and a flip arm connected at an angle of 110 - 130°. The torque of the center of gravity of the flip arm relative to the positioning axis is greater than the torque of the center of gravity of the sealing arm relative to the positioning axis. Under the action of gravity, the flip arm naturally remains in the seal - opening state. In this solution, the flip - type seal door adopts a gravity - release structure, so that after being thrown onto the wire with the help of a drone, it can complete the sealing of the door by its own weight or a tension spring, avoiding accidental detachment and accidental movement of the pulley from the wire and ensuring the safety of the operator.

[0004] The disadvantage of the existing seal - locking pulley is that the hanging and disassembling effect is unstable. Limited by the on - site environmental conditions and the wind direction change at high altitude, when the drone uses the hanging and disassembling tool to place the hanging pulley, the connection and disconnection between the hanging and disassembling tool and the hanging ring, as well as the quick connection and disconnection between the hanging pulley and the wire, all have unstable factors. The hanging and removal of the traction rope are troublesome, and the safe and stable operation of the line is affected due to the prolonged operation time and the wear of the wire and the traction rope. Therefore, designing a device for disassembling and assembling a traction rope, which can be more convenient to operate and have a more stable hanging and disassembling effect with the help of a drone, has always been a research topic in the industry. Summary of the Invention

[0005] The object of the present invention is to provide a device for disassembling and assembling the traction rope of a live working lift based on a drone platform, overcoming the deficiencies of the prior art. Under the action of a torsion spring, the double-card position door is normally in the released angle state. When the device is hung on the wire, the weight of the device itself and the traction rope triggers the double-card position door to flip to the hanging state and is automatically locked by a pin, preventing the pulley from accidentally falling off the wire and ensuring the safety of the operator. When it needs to be detached, when the drone lifts the hook, the pin is lifted at the same time, and the double-card position door opens under the action of the torsion spring and returns to the released angle state, which is more convenient to operate and the hanging and disassembling effect is more stable.

[0006] To achieve the above object, the present invention is realized through the following technical solutions:

[0007] The device for disassembling and assembling the traction rope of a live working lift based on a drone platform includes a suspension bracket, a hook, a double-card position door, a torsion spring, a clamping seat, a pin and a compression spring. The suspension bracket is a deformed U-shaped frame, including a short tail end and a long tail end. A rope pulley is connected to the long tail end. The double-card position door is arranged on the hinge shaft of the short tail end, and a torsion spring is also arranged on the hinge shaft. The double-card position door is in the released angle under the action of the torsion spring. The double-card position door is divided into a guide rod end and a clamping and positioning end with the hinge shaft as the boundary. The arc of the clamping and positioning end matches the U-shaped arc bottom of the suspension bracket, and a clamping groove is arranged at the top of the clamping and positioning end. The clamping seat is centrally arranged on the top of the suspension bracket. The pin is connected to the clamping seat through a pin shaft. The shaft hole where the pin is connected to the pin shaft is a longitudinal long hole. A compression spring is arranged between the pin and the clamping seat, so that when the pin is lifted upward, the compression spring is compressed. The bottom end of the pin matches the clamping groove, and a thread is arranged at the top end of the pin to connect with the hook.

[0008] Further, the long tail end is bent towards the short tail end to form an angle of 135-140°.

[0009] Further, the suspension bracket is composed of two plate members combined through a plurality of connecting pieces. A gap of 20-30 mm is arranged between the two plate members, and at least one connecting piece constitutes a limit for the maximum released angle of the double-card position door.

[0010] Further, the connecting piece is a long nut and two cross-slot countersunk head screws matching with it.

[0011] Further, the hook includes a connecting rod, a ring ear, a linear hook body and a threaded sleeve. The bottom of the connecting rod is connected with the threaded sleeve, and the threaded sleeve is connected with the pin. The top of the connecting rod is connected with the ring ear. 3-4 linear hook bodies are fixedly arranged around the circumference on the connecting rod, and an angle of 45-60° is formed between the linear hook body and the connecting rod.

[0012] Further, the hole distance value of the long hole is greater than the depth of the clamping groove.

[0013] Further, the surface of the rope pulley is provided with an annular groove with an inward concave arc bottom.

[0014] Further, the hook is used in combination with a cross-shaped hanging and detaching net, and the cross-shaped hanging and detaching net is suspended on a hanging rack at the bottom of the unmanned aerial vehicle.

[0015] Further, the cross-shaped hanging and detaching net includes a cross-shaped insulating support and two insulating ropes. The two insulating ropes are respectively connected to the cross-shaped insulating support, and the lower ends of the two insulating ropes cross to form a cross-shaped rope net.

[0016] Further, when the device works, first assemble the unmanned aerial vehicle and the cross-shaped hanging and detaching net on the ground, hook the cross-shaped hanging and detaching net on the hook of the device, and wind the traction rope around the rope pulley of the device; operate the unmanned aerial vehicle to lift the device above the overhead wire, so that the hanging rack falls onto the overhead wire along the double-card position closing door. The unmanned aerial vehicle descends, and the weight of the device itself and the traction rope triggers the double-card position closing door to flip to the hanging state and is automatically caught by the pin at the top, that is, the hanging of the traction rope is completed, and the unmanned aerial vehicle withdraws with the cross-shaped hanging and detaching net; when the device needs to be removed, operate the unmanned aerial vehicle to connect the cross-shaped hanging and detaching net with the hook and lift it upward. At this time, the compression spring is compressed, and the pin is separated from the engaging groove of the double-card position closing door. The double-card position closing door flips to the initial release angle state under the action of the torsion spring, and the device is separated from the overhead wire and is brought back to the ground by the unmanned aerial vehicle, and the operation ends.

[0017] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0018] 1) The double-card position closing door structure is creatively designed. Under the action of the torsion spring, the double-card position closing door is normally in the release angle state, and the guide rod end of the double-card position closing door plays a guiding role, which is convenient for the hanging rack to be hung on the overhead wire;

[0019] 2) When the device is hung on the wire, the weight of the device itself and the traction rope can trigger the double-card position closing door to flip to the hanging state and is automatically caught by the pin at the top, avoiding the accidental detachment of the pulley from the wire and ensuring the safety of the operators;

[0020] 3) When the device needs to be detached, the unmanned aerial vehicle lifts the hook upward, and the pin is lifted at the same time. The double-card position closing door flips open under the action of the torsion spring and returns to the release angle state again. The whole hanging and detaching operation is very convenient, and the hanging and detaching effect is more stable;

[0021] 4) The hook at the top of the device adopts a four-hook design, which is matched with the cross-shaped hanging and detaching net of the unmanned aerial vehicle, reducing the requirement for operation accuracy under high-altitude conditions, making the hanging and detaching of the device easier, the hanging and detaching effect more stable, improving the efficiency of on-site operation, and solving the problem of troublesome hanging and removal of the traction rope.

Obviously, the accompanying drawings in the following description are some embodiments of the present invention. For those of ordinary skill in the art, other drawings can be obtained based on these drawings without creative efforts.

[0032] Generally, the components of the embodiments of the present invention described and shown in the drawings here can be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of the present invention provided in the drawings is not intended to limit the scope of the claimed invention, but merely represents the selected embodiments of the present invention.

[0033] SeeFigure 1-7 , which is a schematic structural diagram of an embodiment of a device for disassembling and assembling the traction rope of a live working lift based on an unmanned aerial vehicle (UAV) platform of the present invention. It includes a hanging bracket 1, a hook 2, a double-position closing door 3, a torsion spring 4, a clamping seat 5, a clamping pin 6, and a compression spring 14. The hanging bracket 1 is a deformed U-shaped frame, including a short tail end 24 and a long tail end 25. A rope pulley 7 is connected to the long tail end 25. The double-position closing door 3 is arranged on a hinge shaft 8 at the short tail end 24, and a torsion spring 4 is also provided on the hinge shaft 8. The double-position closing door 3 is at a release angle under the action of the torsion spring 4. The double-position closing door 3 is divided into a guide rod end 9 and a clamping and positioning end 10 with the hinge shaft 8 as the boundary. The arc of the clamping and positioning end 10 matches the U-shaped arc bottom of the hanging bracket 1, and a clamping groove 11 is provided at the top of the clamping and positioning end 10. The clamping seat 5 is centrally arranged at the top of the hanging bracket 1. The clamping pin 6 is connected to the clamping seat 5 through a pin shaft 12. The shaft hole where the clamping pin 6 is connected to the pin shaft 12 is a longitudinal long hole 13, and the hole pitch value of the long hole 13 is greater than the depth of the clamping groove 11.

[0034] A compression spring 14 is provided between the clamping pin 6 and the clamping seat 5. When the clamping pin 6 is lifted upward, the compression spring 14 is compressed, the bottom end of the clamping pin 6 matches the clamping groove 11, and a thread is provided at the top end of the clamping pin 6 to connect with the hook 2.

[0035] The long tail end 25 is bent towards the short tail end 24 to form an included angle α of 135 - 140°, which is more convenient for the guide rod end 9 to capture the overhead conductor.

[0036] The hanging bracket 1 is composed of two plate members combined through a plurality of connecting members 15. There is a gap of 20 - 30 mm between the two plate members, and at least one connecting member 15 constitutes a limit for the maximum release angle of the double-position closing door 3. In the embodiment, the connecting member 15 is a long nut and two cross recessed countersunk head screws matching with it, which are standard parts and have strong interchangeability.

[0037] The hook 2 includes a connecting rod 16, a ring ear 17, a linear hook body 18, and a threaded sleeve 19. The bottom of the connecting rod 16 is connected to the threaded sleeve 19, the threaded sleeve 19 is connected to the clamping pin 6, the top of the connecting rod 16 is connected to the ring ear 17, and four linear hook bodies 18 are fixedly arranged around the circumferential direction on the connecting rod 16. The included angle between the linear hook body 18 and the connecting rod 16 is 45 - 60°.

[0038] The surface of the rope pulley 7 is provided with an annular groove with an inner concave arc bottom for hanging the traction rope, which plays a role in increasing the contact area and reducing wear. The hook 2 is used in combination with a cross-shaped hanging and disassembling net 20, and the cross-shaped hanging and disassembling net 20 is suspended on a hanging bracket at the bottom of the UAV 21.

[0039] The cross-shaped hanging and detaching net 20 includes a cross-shaped insulating support 22 and two insulating ropes 23. The two insulating ropes 23 are respectively connected to the cross-shaped insulating support 22. The lower ends of the two insulating ropes 23 cross to form a cross-shaped rope net. Its function is to increase the contact opportunity and facilitate the connection with the hook 2. In actual use, as long as one insulating rope can be hooked onto a linear hook body of the hook, the operation purpose can be achieved, without the need to hook all of them. This reduces the requirement for the operation accuracy of the drone under high-altitude conditions, makes the hanging and detaching of the device easier, and the hanging and detaching effect is also more stable.

[0040] When the device is working, first assemble the drone 21 and the cross-shaped hanging and detaching net 20 on the ground. Hook the cross-shaped hanging and detaching net 20 onto the hook 2 of the device, and wind the traction rope around the rope pulley 7 of the device; operate the drone 21 to lift the device above the overhead wire, so that the hanger 1 drops onto the overhead wire along the double-card position closing door 3. The drone 21 descends, and the weight of the device itself and the traction rope triggers the double-card position closing door 3 to flip to the hanging state and is automatically locked by the top pin 6, that is, the connection of the traction rope is completed, and the drone 21 withdraws with the cross-shaped hanging and detaching net 20; when the device needs to be removed, operate the drone 21 to connect the cross-shaped hanging and detaching net 20 with the hook 2 and lift it upward. At this time, the compression spring 14 is compressed, and the pin 6 is separated from the engaging groove 11 of the double-card position closing door 3. The double-card position closing door 3 flips to the initial release state under the action of the torsion spring 4, and the device is separated from the overhead wire 26 and is brought back to the ground by the drone 21, and the operation ends.
