Working principle:

the first step: when the trolley enters the elevator, the trolley is conveniently moved onto the base mechanism 2 by means of the front side surface of the delivery block 108, when the trolley leaves the elevator, the sliding cabin 213 stretches out to the front side, and the delivery block 108 can be pushed by taking the upright column 109 as the axial outer side through the rotating connection of the upright column 109, the movement of the sliding cabin 213 is not blocked by the delivery block 108, the adaptability between components is improved, and in addition, the delivery block 108 after being turned outwards can be carried with the pull plate 110 to be lapped to the floor edge position, so that the stable stop of the car mechanism 1 is facilitated.

And a second step of: through the design of base mechanism 2, when the workman wants the transportation dolly alone, must push the dolly into the elevator earlier, after the wheel of dolly contacted baffle 216, through the existence of pull piece 211, slide storehouse 213 can be followed spout 202 and retreated, and in the in-process of continuously pushing into the dolly, the rear end of slide storehouse 213 can stretch out the protection hole 104 thereby with elevator outer frame joint, make the elevator unable operation, through the design of elevator part, must the workman enter into car 103 in advance, step on inside groove 206 with sole two 209 through the workman, the end embedding of sole two 209 makes slide storehouse 213 joint in draw-in groove 214 at this moment, just can carry the dolly into the elevator at this moment, in the elevator transportation, the workman is restricted inside the elevator by the dolly, thereby ensure that the dolly has a person to take care all the time, improve the transportation safety of goods.

And a third step of: through the design of recess 215, after the workman stands in advance and decides the position, drags the dolly again, just can sink into the upper surface of recess 215 after the wheel of dolly is drawn across baffle 216, and there is baffle 216 to block the wheel in the position that the dolly was advanced simultaneously for the dolly can not move forward or rock about in the operation in-process of elevator, and there is the workman to control the rear side, improves the transportation security of dolly.

Fourth step: by the design of the standing block 205, the range of the workers and the trolley on the base 201 is limited, the balance of the positions of the workers and the trolley is ensured, the gravity bearing of the elevator is more average, and the operation safety of the elevator is improved.

Fifth step: after the elevator reaches the appointed floor, the worker steps on the foot block 501 through both feet, thereby drive horizontal case 506 and wholly move downwards, thereby make tooth 509 and gear 402's tooth mesh, briquetting 510 moves down and presses switch 403 and start motor 401 rotation simultaneously, after rotating one hundred eighty degrees, briquetting 510 rotates the top of leaving switch 403, at this moment gear 402 stops rotating, base 201 rotates one hundred eighty degrees under the drive of slewing mechanism 5, thereby with the position of people and dolly exchange, through the design of elevator part, make the workman go up and down the elevator and all can adopt the mode of back pulling the dolly to go on, when making the dolly business turn over elevator, the workman can more convenient laborsaving promotion dolly, improve the convenience of dolly business turn over.

Sixth step: when the base 201 rotates, the bottom block 218 extrudes the air bag 305 inside the bottom frame 302, so that air inside the air bag 305 is transmitted into the air cylinder 210 through the air valve tube 219 and the air tube 217, after a worker leaves the elevator, the sliding cabin 213 loses clamping connection, and at the moment, under the action of inflation of the air cylinder 210, the sliding cabin 213 is pushed to move towards the elevator door, and the trolley is driven to move out of the elevator, so that unloading of the elevator is more labor-saving.

Seventh step: when the elevator is empty, the base 201 can be slowly returned under the action of the second spring 307, and the automatic return capability of the base mechanism 2 is improved.

Eighth step: when the trolley moves out of the elevator, the sliding cabin 213 stretches out to facilitate the connection of the elevator and the floor, and on the other hand, the sliding cabin can block the closing of the elevator door to ensure the safety during unloading.

Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made therein without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
