The working principle is as follows:

the first step is as follows: when the trolley enters the elevator, the delivery block 108 is convenient to move onto the base mechanism 2 by means of the front side face of the delivery block 108, when the trolley leaves the elevator, the sliding cabin 213 extends towards the front side and is connected through rotation of the upright column 109, so that the delivery block 108 can be pushed by taking the upright column 109 as the axial outer side, the delivery block 108 does not block movement of the sliding cabin 213, adaptability among components is improved, and in addition, the delivery block 108 which is overturned outwards can also be lapped to a floor edge position with the pull plate 110, so that stable stopping of the car mechanism 1 is facilitated.

The second step is that: through the design of the base mechanism 2, when a worker wants to transport a trolley independently, the trolley must be pushed into the elevator firstly, after wheels of the trolley contact the baffle 216, the sliding cabin 213 can retreat along the sliding groove 202 through the existence of the pull block 211, and in the process of continuously pushing the trolley, the rear end of the sliding cabin 213 can extend out of the protection hole 104 to be clamped with an outer frame of the elevator, so that the elevator cannot run, through the design of elevator components, the worker must enter the car 103 in advance, the worker steps the foot plate II 209 into the inner groove 206, at the moment, the end of the foot plate II 209 is embedded into the clamping groove 214 to be clamped with the sliding cabin 213, at the moment, the trolley can be transported into the elevator, and in the process of transporting the elevator, the worker is limited inside the elevator by the trolley, so that the trolley is ensured to have one person to take charge all the time, and the transportation safety of goods is improved.

The third step: through the design of concave plate 215, after the workman stands the location in advance, drag the small handcart again, just can be absorbed in concave plate 215's upper surface after the wheel of small handcart passes baffle 216 and caves in, there is baffle 216 to block the wheel in the position that the small handcart went forward simultaneously for the small handcart can not move forward or rock about in the operation of elevator, and there is the workman to control the rear side, improves the transportation security of small handcart.

The fourth step: through the design of the station block 205, the range of the workers and the trolleys existing on the base 201 is limited, the balance of the positions of the workers and the trolleys is ensured, the gravity bearing of the elevator is relatively even, and the operation safety of the elevator is improved.

The fifth step: after the elevator arrives at the appointed floor, the worker steps on the foot block 501 through two feet, thereby the horizontal box 506 is driven to move down integrally, thereby the teeth 509 are engaged with the teeth of the gear 402, meanwhile, the pressing block 510 moves down to press the switch 403 to start the motor 401 to rotate, after rotating one hundred eighty degrees, the pressing block 510 rotates away from the upper side of the switch 403, at the moment, the gear 402 stops rotating, the base 201 rotates one hundred eighty degrees under the driving of the rotating mechanism 5, thereby the positions of people and the trolley are exchanged, through the design of elevator components, the elevator can be lifted up and down by the worker in a mode of pulling the trolley backwards, when the trolley goes in and out of the elevator, the worker can push the trolley more conveniently and more laborsavingly, and the convenience of the trolley entering and exiting is improved.

And a sixth step: when the base 201 rotates, the bottom block 218 presses the air bag 305 inside the bottom frame 302, so that the air inside the air bag 305 is transmitted to the inside of the air cylinder 210 through the air valve pipe 219 and the air pipe 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, so that the trolley is driven to move out of the elevator, and the unloading of the elevator is more labor-saving.

The seventh step: when the elevator is unloaded, the base 201 can slowly return 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 extends out to facilitate the rail connection between the elevator and the floor, and on the other hand, the elevator door can be blocked to be closed, so that the safety during unloading is ensured.

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