The top side of the supporting beam 102 is fixedly connected with a mounting seat 601, and a hydraulic cylinder 602 is fixedly installed on one side of the mounting seat 601. The output end of the hydraulic cylinder 602 is fixedly connected to the double-groove guide wheel 603 , two connecting steel wire ropes 604 are arranged inside the wheel groove of the double-groove guide wheel 603, one end of the two connecting steel wire ropes 604 are fixedly connected with a hook 605 connected to the connecting lifting ring 5, the other end of the two connecting steel wire ropes 604 are fixedly connected with a connecting sleeve 606, the inside of the two connecting sleeves 606 are threadedly connected with an adjusting threaded rod 607, and one side of the supporting crossbeam 102 is rotatably connected with a plurality of single-groove guide wheels 608 that guide the connecting steel wire ropes 604. When it is necessary to lift the material to a certain height, the hydraulic cylinder 602 is first started to shrink its output end, and the double-groove pulley 603 moves upward at this time. In the process of the double-groove pulley 603 moving upward, the connecting pulley 603 is made to move upward under the action of the gravity of the lifting platform 3.

[0028] As an optional technical solution of the present invention, a part of the connecting wire rope 604 is located inside the single-groove guide wheel 608, and the diameter of the connecting wire rope 604 is equal to the width of the wheel groove of the single-groove guide wheel 608. The connecting wire rope 604 is supported by a number of single-groove guide wheels 608, so that one end of the connecting wire rope 604 can smoothly perform rising and falling operations.

[0029] A platform lifting mechanism, the working principle is as follows:

[0030] 1) Start the hydraulic cylinder 602 to shrink its output end, and the double-groove pulley 603 moves upward. During the upward movement of the double-groove pulley 603, the hanging plate 4 moves downward under the action of the single-groove guide wheel 608, the hook 605 and the connecting ring 5, so that the guide shell 2 drives the lifting platform 3 to move downward. When the output end of the hydraulic cylinder 602 is fully retracted, the bottom side of the lifting platform 3 contacts the ground;

[0031] 2) Transfer the goods to the lifting platform 3;

[0032] 3) Start the hydraulic cylinder 602 to extend its output end. At this time, the double-groove pulley 603 moves downward, thereby moving a part of the connecting wire rope 604 downward. At this time, under the action of the single-groove guide wheel 608, the hook 605 and the connecting ring 5, the hanging plate 4 moves upward, so that the guide shell 2 drives the lifting platform 3 and the material to a suitable height.

[0033] To sum up, the platform lifting mechanism, through the coordinated arrangement of the support frame structure 1, the guide shell 2, the lifting platform 3, the hanging plate 4, the connecting ring 5 and the lifting mechanism 6, can lower the lifting platform 3 to a lower position when it is necessary to lift materials, so that the lifting platform 3 can be in contact with the ground. When it is necessary to manually transfer the goods to the lifting platform 3, there is no need to lift the goods to a higher position, thereby reducing the labor intensity of the operator in lifting the goods, and at the same time, the four corners of the lifting platform 3 are lifted to ensure the stability of the lifting platform 3 during the lifting process.
