Description

TECHNICAL FIELD

[0001] The utility model relates to battery carrying tool technical field, in particular to a nuclear power station battery hoisting device. BACKGROUND

[0002] Nuclear power generation is a clean and efficient energy generation mode, but the safety requirement is also the highest among numerous types of power stations. In order to ensure the safe and stable operation of nuclear power stations, lead storage batteries are used as emergency backup power supply in nuclear power stations all over the world. These lead storage batteries need to be replaced as a whole after being used for a period of time, and the old lead storage batteries need to be carried out first, and then the new ones are carried in. The carrying of lead storage batteries is an important and frequent work in nuclear power stations.

[0003] The traditional battery hoisting method is relatively simple, and there is no special tool. In the utility model patent with the application publication number CN112047266 A, a carrying auxiliary device for grabbing the battery by using a vacuum chuck is provided. The operation of this device is still inconvenient, and the vacuum chuck needs to be operated by the operator alone. The traction, alignment and opening of the chuck operation are not efficient. Even in some places, manual carrying is still used. Although the efficiency is high, the labor intensity is large, and the manual carrying process is easy to cause the battery to slip due to improper operation, causing personnel injury and equipment damage. Using ordinary forklifts is obviously not suitable for the size of lead storage batteries, and batch carrying cannot reliably fix the storage batteries, which is easy to shake, shift, even fall, and still has safety hazards.

[0032] The vehicle body assembly 100 comprises a vehicle frame 110 and a movable chassis 120, and the vehicle frame 110 is arranged on the chassis 120. Specifically, the vehicle frame 110 is arranged on one side of the top end surface of the chassis 120 to leave space for the telescopic assembly 200. The telescopic assembly 200 comprises a driving part, a scissor-type telescopic frame 220 and a loading part 230. The driving part is arranged on the chassis 120 to drive the scissor-type telescopic frame 220 to lift along the normal direction of the chassis 120 and to extend in the horizontal direction. The loading part 230 is arranged on the free end of the scissor-type telescopic frame 220. Due to the adoption of the scissor-type telescopic frame 220, the scissor-type telescopic frame 220 can be driven by the driving part to extend in the horizontal direction and to move in the vertical direction, i.e. along the normal direction of the chassis 120, so as to realize the extension of the loading part 230 to the position of the storage battery, load and lift the storage battery on the loading part 230, and then drive the scissor-type telescopic frame 220 to retract by the driving part, so that the scissor-type telescopic frame 220 and the storage battery return to the top end surface of the chassis 120 of the vehicle body assembly 100. The chassis 120 is moved to carry the storage battery to other positions.

[0033] The nuclear power station storage battery hoisting device provided by the utility model realizes the extension and retraction of the scissor-type telescopic frame 220 in the horizontal direction and the lifting of the scissor-type telescopic frame 220 in the vertical direction by one driving part, has simple structure, and is better adapted to the carrying operation of the nuclear power station storage battery, so as to solve the problems of great labor intensity, poor safety, insufficient operation flexibility and poor universality of the existing storage battery carrying mode, and improve the carrying efficiency of the nuclear power station storage battery.

[0034] Specifically, in one of the embodiments of the utility model, as shown in Figure 1As shown, the driving part comprises a transmission screw 211, a sliding block 212 and a telescopic motor 213; the telescopic motor 213 is arranged on the chassis 120, the transmission screw 211 is arranged along the normal direction of the chassis 120 and is in transmission connection with the telescopic motor 213, and the sliding block 212 is threadedly connected on the transmission screw 211; the scissor-type telescopic frame 220 comprises a telescopic swing arm 221 and a telescopic rod 222, the first end of the telescopic swing arm 221 is hinged on the chassis 120, the second end of the telescopic swing arm 221 is hinged on the telescopic rod 222, the first end of the telescopic rod 222 is hinged on the sliding block 212, and the loading part 230 is arranged on the second end of the telescopic rod 222. The telescopic motor 213 is fixed on the chassis 120, drives the transmission screw 211 to rotate clockwise or counterclockwise around the shaft, so that the sliding block 212 can be raised and lowered on the transmission screw 211.
