Based on the same inventive concept, the embodiment of the invention also provides a method for transferring electric power materials by using the electric power material transferring equipment, wherein the method for transferring the electric power materials comprises the following steps:

s1, placing electric power materials into a conveying box body 2, and starting a transfer car body 1 to walk;

s2, when the transfer car body 1 walks to the front of a step, the front support frame 13 stretches out and is supported on the top surface of the first step, the telescopic oil cylinder 122 drives the rear wheel set 12 to stretch out, meanwhile, the front support frame 13 vertically swings to cooperate with the rear wheel set 12 to enable the transfer car body 1 to lift upwards, and the rear wheel set 12 rotates to enable the transfer car body 1 to walk forwards until the front wheel set 11 moves to the first step;

s3, the rear supporting frame 14 stretches out and supports on the ground to support the transfer car body 1 by matching with the front wheel set 11, the front supporting frame 13 is lifted, meanwhile, the telescopic oil cylinder 122 drives the rear wheel set 12 to retract, the front wheel set 11 rotates to drive the transfer car body 1 to walk forwards until the rear wheel set 12 moves to a first stage of step, and the rear supporting frame 14 is retracted;

s4, repeating the steps S2-S3 until the transfer vehicle body 1 climbs all steps;

s5, starting a lifting mechanism 3 before the transfer car body 1 walks to a goods shelf, so that the conveying box body 2 is lifted to a position where the base plate 22 is flush with a target goods shelf layer;

s6, opening the turnover plate 24 to be in a horizontal state, and starting the transverse pushing assembly 21 to enable the pushing plate 211 to move forwards to the front end of the base plate 22 so as to push electric materials forwards;

s7, starting a conveyor belt assembly 241, and continuously and forwards conveying the electric materials above the turnover plate 24 to the target shelf layer;

s8, retracting the overturning plate 24, resetting the pushing plate 211, and descending and resetting the lifting mechanism 3.

When electric power materials are required to be transferred from the truck to the electric power material transferring equipment, the lifting mechanism 3 can be lifted to the position of the conveying box body 2 to be matched with the unloading position of the truck, so that the electric power materials can be directly transferred from the truck to the conveying box body 2.

After loading is completed, the lifting mechanism 3 is lowered to the lowest state so as to ensure the stability of the transportation process. When walking on the flat ground, the front support frame 13 and the rear support frame 14 are in a retracted state, and meanwhile, the camera positioned above the front of the transfer vehicle body 1 can monitor the obstacle in front of the transfer vehicle body 1 in real time so as to avoid collision with the outside.

When the transfer car body 1 walks to the front of the step, the camera sends out signals to the controller, and the controller sequentially controls the actions of all the components to realize the stair climbing transfer of the electric power material transfer equipment. Firstly, a front supporting frame 13 extends forwards to be supported on a table top of a first-stage step, a rear wheel set 12 extends downwards, the supporting angle between the front supporting frame 13 and a transferring vehicle body 1 is reduced along with the extension of the rear wheel set 12, the transferring vehicle body 1 is lifted to be level with the bottom of the front wheel set 11 and the table top of the first-stage step under the combined supporting action of the rear wheel set 12 and the front supporting frame 13, and at the moment, the transferring vehicle body 1 moves forwards to be positioned on the table top of the first-stage step by rotating the rear wheel set 12 under the supporting state of the rear wheel set 12 and the front supporting frame 13; subsequently, the rear supporting frame 14 extends downward to the rear to be supported on the ground, the front supporting frame 13 is lifted, at the moment, the rear supporting frame 14 and the front wheel set 11 support the transferring vehicle body 1 together, the rear wheel set 12 is retracted, the front wheel set 11 rotates to enable the transferring vehicle body 1 to move forward continuously until the rear wheel set 12 is positioned on the table top of the first-stage step, then the rear supporting frame 14 is retracted, and meanwhile the front supporting frame 13 extends forward to be supported on the table top of the second-stage step, and climbing of the second-stage step is continued. In the process, a distance sensor positioned on the transfer car body 1 monitors the distance between the transfer car body 1 and the step in real time, and sends a distance signal to the controller so that the controller can control the linkage action of each part. After repeating the above steps until the rear wheel set 12 climbs up to the table top of the last stage of step, the front support frame 13 and the rear support frame 14 are retracted.

After the stair climbing transportation is completed, the transfer car body 1 walks to the goods shelf, the lifting mechanism 3 starts and drives the conveying box body 2 to be lifted to the position that the base plate 22 is flush with the target goods shelf layer, the overturning cylinder 26 stretches out to drive the overturning plate 24 to be overturned forwards to be in a horizontal opening state, at the moment, the base plate 22 and the overturning plate 24 are positioned in the same plane with the target goods shelf layer, the rotary driving piece 214 is started, the pushing plate 211 is driven to push the electric materials positioned in the conveying box body 2 forwards, when the pushing plate 211 moves to the front end of the base plate 22, the conveyor belt assembly 241 is started, the electric materials staying above the overturning plate 24 are continuously conveyed forwards to the target goods shelf layer, finally, the overturning cylinder 26 is retracted to drive the overturning plate 24 to be overturned backwards to be in an upright closing state, meanwhile, the pushing plate 211 slides backwards to an initial position, and the lifting mechanism 3 descends to the lowest position. Thus, the transfer of the electric power materials is completed.

The foregoing description of the preferred embodiments of the invention is not intended to be limiting, but rather is intended to cover all modifications, equivalents, and alternatives falling within the spirit and principles of the invention.
