[0030] In this embodiment, the battery is used to supply power to the electric equipment, and the controller is used to drive the motor to open and close. When the trolley is lifted, the guide plate 31 is used for guiding, which is convenient for pushing the trolley onto the lifting plate 26. When the trolley is pushed onto the lifting plate 26, the tires on both sides of the trolley are pushed into the limiting grooves 35 on the corresponding side. After being pushed in, the guide plate 31 is turned over, and the clamping plate 32 is clamped on the clamping rod 33 to fix the guide plate 31. Through the double fixation of the guide plate 31 and the limiting groove 35, the stability of the trolley during lifting is ensured. When facing different wheelbases of the trolley, the third motor 39 is started to drive the second screw 38 to rotate. The rotation of the second screw 38 can drive the sliders 36 on both sides to move synchronously and reversely. The movement of the sliders 36 can drive the limiting grooves 35 on both sides to move synchronously and reversely. By changing the position of the limiting groove 35, the trolley with different wheelbases can be fixed.

[0031] Meanwhile, the contents not described in detail in the specification all belong to the prior art known by those skilled in the art.

[0032] Working principle: when using the material lifting device, first push the frame 1 to the appropriate position, the universal wheels 4 at the bottom of the frame 1 facilitate movement, and the handle 5 at the top facilitates operation. The construction trolley is pushed onto the lifting plate 26 through the guide plate 31, and the tire of the trolley falls into the limiting groove 35. The controller in the control box 6 is started to drive the first motor 24 to operate. The output end of the first motor 24 drives the first screw 22 to rotate. The lifting plate 26 stably rises along the first screw 22 because it is screwed with the first screw 22 and the limiting rod 21 penetrates through it. When it rises to the upper table height, the second motor 29 is started, and the gear 28 at the output end of the second motor 29 drives the gear ring 27 to rotate, thereby making the rotating block 25 rotate and driving the lifting plate 26 above to rotate horizontally to the appropriate position, which facilitates the removal of the trolley. If the wheelbase of the trolley is different, the third motor 39 is started, and the output end of the third motor 39 drives the second screw 38 to rotate. Because the threads on both sides of the second screw 38 are different, the sliders 36 screwed on both sides move synchronously and reversely, driving the limiting grooves 35 to adjust the position to adapt to the wheelbase of the trolley. The whole process is powered by the battery, and the controller accurately controls the operation of each motor.
