Description

Technical Field

[0001] The invention relates to the field of unmanned aerial vehicle transportation hooks, and in particular to an auxiliary hook for transporting spacer bars using unmanned aerial vehicles. Background Art

[0002] In the maintenance of power lines, the transportation and installation of spacers is a crucial link. Traditional transportation methods mainly rely on manpower, which is not only inefficient but also has high safety risks, especially in complex terrain or severe weather conditions. In recent years, although technologies such as aerial platforms and climbing robots have been introduced, the applicability of these devices is limited in certain scenarios, such as steep slopes or soft ground. The development of drone technology provides a new idea for solving this problem. Compared with aerial platforms and climbing robots, drones have higher flexibility, stronger terrain adaptability and lower maintenance costs. However, existing drone lifting systems often lack professional designs for spacer transportation, resulting in certain operational difficulties and safety risks in practical applications. Therefore, designing an auxiliary hook designed specifically for drone lifting of spacers is of great significance for improving transportation efficiency and reducing safety risks. Summary of the invention

[0003] The technical problem to be solved and the technical task proposed by the present invention are to improve and perfect the existing technical solutions, and provide an auxiliary hook for transporting spacer bars by using drones, so as to facilitate the drones to lift and mount the spacer bars on the cable lines. To this end, the present invention adopts the following technical solutions.

[0004] An auxiliary hook for transporting spacer bars by using an unmanned aerial vehicle comprises a hook body, a buckle and a guide connector, wherein the upper end of the buckle can be rotatably connected to the inner side of one side of the upper part of the hook body, an elastic member is provided between the buckle and the hook body to make the lower end of the buckle elastically contact with the inner side of the other side of the hook body, so that the buckle and the hook body form a closed cable mounting hook hole that can be pressed downward, a lower hanging rope connecting hole for lifting the spacer bars is provided at the lower part of the hook body, the lower end of the guide connector is connected to the upper end of the hook body, the upper end of the hook body is provided with an upper hanging rope connecting hole for the hanging rope to pass through, and the guide connector is provided with a vertical through hole for passing the hanging rope. The auxiliary hook can be mounted on the cable line through the cable mounting hook hole, the lower hanging rope connecting hole is connected to the fixed spacer through the lower hanging rope, and the upper hanging rope passes through the upper hanging rope connecting hole and the vertical through hole to be mounted on the drone hook, which can facilitate the transportation of spacers by drone and the mounting on the power transmission line cable line. The hanging rope passes through the vertical through hole, so that the auxiliary hook is more stable when transporting the drone.

[0005] As a preferred technical means: the guide connector is provided with a guide side for guiding and aligning the axial direction of the hook body with the axial direction of the cable line, and the guide side is on the same side as the opening direction of the upper part of the hook body. When the auxiliary hook is hoisted by the UAV, due to reasons such as the flight angle and the rotation of the hoisting rope, the axial direction of the hook body of the auxiliary hook is not consistent with the axial direction of the cable line of the power transmission line, which will cause difficulty in mounting. By setting the guide side, the axial direction of the hook body can be effectively guided and aligned with the axial direction of the cable line during the mounting process, and guided to the opening position of the hook body on the same side, reducing the difficulty of operation and the risk of misoperation.

[0006] As a preferred technical means: the guide connector includes a cone-shaped body with a small top and a large bottom and two guide wings, the guide side is between the two guide wings, the two guide wings are symmetrically arranged according to the symmetric center plane of the hook body, and the vertical through hole is arranged at the axial position of the cone. To realize the guide connector structure, when the auxiliary hook moves upward, the cone-shaped body with a small top and a large bottom is convenient for good guidance during the process of mounting on the cable. When the auxiliary hook moves upward, the cable touches the guide wings to force the auxiliary hook to rotate, and gradually rotates until the axial direction of the hook body is consistent with the cable to achieve angle adjustment.

[0007] As a preferred technical means: the two guide wings are gradually rotated from the back side of the cone to the front side of the cone from top to bottom, and the front side is the side where the cable mounting hook hole is located, which serves as the guide side. This structure makes the guide redundant angle range of the cable larger when the auxiliary hook moves upward, making the auxiliary hook relatively easier to operate.

[0008] As a preferred technical means: the guide connector is connected to the hook body via a pin, which makes the connection stable and reliable.

[0009] As a preferred technical means: the buckle and the hook body are rotatably connected by bolts. Since the buckle is often rubbed against the cable, it is relatively easy to be damaged. The rotatable connection by bolts facilitates the disassembly and maintenance of the buckle.

[0010] As a preferred technical means: the hook body and the buckle are both provided with an anti-slip rubber layer, which can effectively increase the friction between the auxiliary hook and the cable, and when the auxiliary hook is mounted on the cable, the relative movement probability between the auxiliary hook and the cable can be reduced, and scratches on the cable protective metal layer can also be avoided.

[0011] As a preferred technical means: the hook body and the anti-skid rubber layer, the buckle and the anti-skid rubber layer are bonded by adhesive. The anti-skid rubber layer can be in the form of a rubber jacket and put on the buckle and the hook body, and the two are bonded by adhesive, so that the anti-skid rubber layer is more firm and not easy to fall off.

[0012] As a preferred technical means: the hook body is made of aviation laminate or light aluminum alloy. It has excellent properties such as light weight, high strength, corrosion resistance, etc., which is convenient for drone lifting.

[0013] Beneficial effect: the auxiliary hook can be mounted on the cable line through the cable mounting hook hole, the lower hanging rope connecting hole can be connected to the spacer through the lower hanging rope, the upper hanging rope passes through the upper hanging rope connecting hole and the vertical through hole to be mounted on the drone hook, and the hanging rope passes through the vertical through hole, so that the auxiliary hook is more stable during drone transportation, and the spacer can be conveniently transported by drone and mounted on the power transmission line cable line. The guiding connector helps to guide the hook body to align with the cable line during the mounting process, making the mounting more convenient. BRIEF DESCRIPTION OF THE DRAWINGS

[0020] The technical solution of the present invention is further described in detail below in conjunction with the accompanying drawings.

[0021] like Figure 1-5As shown, an auxiliary hook for transporting spacer bars by using a drone comprises a hook body 1, a buckle 3 and a guide connector, the upper end of the buckle 3 is rotatably connected to the inner side of one side of the upper part of the hook body 1, a torsion spring 8 as an elastic member is provided between the buckle 3 and the hook body 1 to make the lower end of the buckle 3 elastically contact with the inner side of the other side of the hook body 1, so that the buckle 3 and the hook body 1 form a closed cable hanging hook hole that can be pressed downward, the lower part of the hook body 1 is provided with a lower hanging rope connection hole 2 for hanging the spacer bars, the lower end of the guide connector is connected to the upper end of the hook body 1, the upper end of the hook body 1 and the lower end of the guide connector are provided with an upper hanging rope connection hole 7 with the same axis for the hanging rope to pass through, and the guide connector is provided with a vertical through hole 5 for passing the hanging rope. The guide connector is provided with a guide side for guiding the hook body 1 to be aligned with the axial direction of the cable, and the guide side is on the same side as the opening direction of the upper part of the hook body 1.

[0022] In order to adjust the guide angle between the auxiliary hook and the cable, the guide connector includes a cone 4 with a small top and a large bottom and two guide wings 6. The guide side is between the two guide wings 6. The two guide wings 6 are symmetrically arranged according to the symmetric center plane of the hook body 1, and the vertical through hole 5 is set at the axial position of the cone 4. To achieve the guide connector structure, when the auxiliary hook moves upward, the cone 4 with a small top and a large bottom is convenient for good guidance during the process of mounting on the cable. When the auxiliary hook moves upward, the cable touches the guide wings 6 to force the auxiliary hook to rotate, and gradually rotates until the axial direction of the hook body 1 is consistent with the cable, so as to achieve the adjustment of the guide angle.

[0023] In order to facilitate the guidance during mounting, the two guide wings 6 are gradually rotated from the back side of the cone 4 to the front side of the cone 4 from top to bottom. The front side is the side where the cable mounting hook hole is located, which serves as the guiding side. This structure makes the guide redundant angle range of the cable larger when the auxiliary hook moves upward, making the auxiliary hook relatively easier to operate and more convenient for guidance during mounting.

[0024] In order to increase the friction between the hook body 1 and the buckle 3, an anti-slip rubber layer is provided. The friction between the hook body 1 and the buckle 3 can effectively increase the friction between the hook body 1 and the cable. When the auxiliary hook is mounted on the cable, the relative movement probability between the auxiliary hook and the cable can be reduced, and the scratching of the cable protective metal layer can be avoided.

[0025] In order to make the anti-skid rubber layer more firm and not easy to fall off, the hook body 1 and the anti-skid rubber layer, the buckle 3 and the anti-skid rubber layer are bonded by adhesive. The anti-skid rubber layer can be in the form of a rubber jacket and put on the buckle 3 and the hook body 1, and the two are bonded by adhesive, so that the anti-skid rubber layer is more firm and not easy to fall off.

[0026] In order to prevent the hook body 1 and the guide connector from being reversed during assembly, a foolproof structure is provided between the upper end of the hook body 1 and the guide connector. In this example, the foolproof structure adopts a T-slot matching structure. The foolproof structure can prevent the reverse installation during assembly, making assembly easier.

[0027] In this example, the guide connector is connected to the hook body 1 via a pin. The pin connection provides a stable and reliable connection.

[0028] In this example, bolts are used to realize the rotatable connection between the buckle 3 and the hook body 1. Since the buckle 3 often rubs against the cable, it is relatively easy to be damaged. The rotatable connection with bolts makes it easy to disassemble and maintain the buckle 3.

[0029] In this example, the hook body 1 is made of aviation plywood. Aviation plywood has low cost, light weight, good processing performance, and is convenient for drone lifting. In this example, light aluminum alloy can also be used instead of aviation plywood.

[0030] When the spacer bar is transported, the operator connects the spacer bar and the lower rope connection hole 2 through the rope, and the drone takes off and hangs in the air, lowers the drone hook, and the rope passes through the upper rope connection hole 7 and the vertical through hole 5 and then mounts it on the drone hook. The drone retracts the hook and starts flying after ensuring that the spacer bar no longer shakes. The drone flies 5-7 meters above the target cable line. If the mounted cable line is the uppermost layer, pay attention to the hidden line. If the mounted cable line is the middle or lower layer, be careful not to touch the upper cable line. The drone adjusts the camera downward to capture the cable line. The cable is placed at the paint dotted position, the lifting rope is lowered, the guide connector is under the cable, and then the lifting rope is gradually retracted upwards to move the auxiliary hook upwards. The cable is gradually turned by the guide side to adjust the angle and then the buckle 3 is pressed downwards. After the cable enters the cable mounting hook hole, the buckle 3 rebounds upwards to close the cable mounting hook hole, and then the lifting rope is gradually lowered. When the drone hook detects that there is no tension, the drone hook releases the lifting rope and automatically detaches from the auxiliary hook. The auxiliary hook is mounted on the cable, the transport and mounting of the spacer bar is completed, and the drone returns. It is convenient to transport the spacer bar and mount it on the cable of the power transmission line through the drone.

[0031] above Figure 1-5 The auxiliary hook shown in the figure for transporting spacer rods using a drone is a specific embodiment of the present invention, which has embodied the outstanding substantial features and significant progress of the present invention. According to actual use needs and under the guidance of the present invention, equivalent modifications can be made to its shape, structure, etc., which are all within the protection scope of this scheme.
