[0002] An aerial work vehicle with a remote service system is a work vehicle with remote operation function. With the remote operation function, the operator can remotely control the movement, posture and working equipment of the work vehicle through the network, such as controlling the height, direction, speed, etc.

[0003] In the prior art, aerial work with a remote service system is generally divided into two types: one is a straight-arm aerial work vehicle, in which the lift is a straight-arm structure and is lifted and lowered by hydraulic control; the other is a scissor-type aerial work vehicle, in which the lift is a scissor-type structure and is lifted and lowered by a screw module.

[0004] Since the scissor-type aerial work vehicle lifts vertically and is used in weather with high wind speed and force, and since the scissor-type aerial work vehicle is not equipped with a traction structure, the working platform at the top of the lift is prone to shaking, making it more difficult for the workers on it to operate.

On one side, a third sprocket 8 is arranged on the left side of the interior of the second transmission housing 7, a driven gear 9 is arranged on the other side of the first transmission housing 4, a driving gear 10 is arranged on the left side of the first transmission housing 4 near the driven gear 9, a fourth sprocket 11 is arranged on the axial side of the driving gear 10, the fourth sprocket 11 is movably connected with the third sprocket 8 through a chain, the driving gear 10 is meshed with the driven gear 9, the left capstan 5 is fixedly connected with the third sprocket 8 through a rotating shaft, the right capstan 5 is fixedly connected with the driven gear 9 through a rotating shaft, and the first transmission housing 4 is arranged on one side of the left winding mechanism and the scissor lift 3;

[0029] In this embodiment, after the double-axis motor 12 is started, the second sprocket 13 and the first sprocket 14 cooperate with the chain to drive the winch 5 on the left to release the traction rope 6. When the winch 5 on the left rotates, the other end drives the driving gear 10 to rotate through the third sprocket 8 and the fourth sprocket 11 and the chain. The driving gear 10 is meshed with the driven gear 9 to control the winch 5 on the right to release the traction rope 6 in the opposite direction, and the other end of the double-axis motor 12 drives the worm 15 to rotate, and the worm 15 drives the lead screw 16 to rotate through the worm wheel 17. After the lead screw 16 rotates, the scissors-type lift 3 is controlled to rise. In this way, during the process of taking off and lowering the scissors-type lift 3, the traction rope 6 is synchronously retracted and released, and the traction rope 6 can pull the two ends after the scissors-type lift 3 is raised, so that the structure of the scissors-type lift 3 is more stable in windy weather.

When the winch 5 on the left rotates, the other end drives the driving gear 10 to rotate through the third sprocket 8 and the fourth sprocket 11 in cooperation with the chain. The driving gear 10 and the driven gear 9 are meshed and transmitted to control the winch 5 on the right to release the traction rope 6 in the opposite direction, and the other end of the double-axis motor 12 drives the worm 15 to rotate, and the worm 15 drives the lead screw 16 to rotate through the worm wheel 17.
