Detailed Description

The following description of the embodiments of the present invention is provided for illustrative purposes, and other advantages and effects of the present invention will be readily apparent to those skilled in the art from the disclosure herein. The present invention can also be implemented or applied through other different specific embodiments, and various details in the present specification can be modified or changed based on different viewpoints and applications without departing from the spirit of the present invention. It is to be noted that the features in the following embodiments and examples may be combined with each other without conflict.

It should be noted that the drawings provided in the following embodiments are only for illustrating the basic concept of the present invention, and the components related to the present invention are only shown in the drawings rather than drawn according to the number, shape and size of the components in actual implementation, and the form, amount and ratio of the components in actual implementation may be changed at will, and the layout of the components may be more complicated.

Examples

Referring to fig. 1, the heavy goods lift comprises a bottom beam 1, a lifting platform 2, a hydraulic cylinder 3 and at least one group of lifting frames, wherein the lifting platform 2 is arranged right above the bottom beam 1 in parallel through the lifting frames, each group of lifting frames comprises a front lifting frame and a rear lifting frame which are hinged in an X shape and are symmetrical front and back, a plurality of cross rods 4 parallel to the bottom beam 1 are arranged between the front lifting frame and the rear lifting frame, the number of the cross rods 4 can be set to be 4-8, and the lifting frames are specifically adjusted according to the height of the lifting frames; the hydraulic cylinder 3 is hinged between two adjacent cross rods 4; the front lifting frame and the rear lifting frame respectively comprise a first connecting rod 5 and a second connecting rod 6, the middle parts of the first connecting rod 5 and the second connecting rod 6 are hinged in a crossed mode through a connecting pin 12, the rotation is flexible, a lower sliding rail 9 is installed on the upper end face of the bottom beam 1, an upper sliding rail 7 is installed on the lower end face of the lifting platform 2, an upper roller 8 matched with the upper sliding rail 7 is installed on the upper end of the first connecting rod 5, the upper roller 8 is installed in the upper sliding rail 7 in a sliding mode, and the lower end of the first connecting rod 5 is hinged and fixed with the bottom beam 1; the lower end of the second connecting rod 6 is provided with a lower roller 10 matched with the lower sliding rail 9, the lower roller 10 can be slidably arranged in the lower sliding rail 9, and the upper end of the second connecting rod 6 is hinged and fixed with the lifting platform 2.
