A large box-type device that requires the top cover to be opened

Abstract

The invention discloses a large-scale box-type equipment that needs to be opened with a top cover, which includes a box body, a top cover, a cover opening hinge and a cover opening drive assembly, the top cover is connected to the box body through the cover opening hinge, and the cover opening hinge includes a connecting rod and the first hinge shaft; the cover-opening drive assembly includes a cover-opening mechanism, a base and a support, the cover-opening mechanism includes an electric push rod and a drive shaft, the base is installed on the top cover and the support is installed on the box One end of the electric push rod is hinged on the base through the second hinge shaft and the other end is hinged on the inner wall of the box body through the third hinge shaft, the third hinge shaft, the second hinge shaft and the first hinge shaft The hinge axes are parallel to each other and they are distributed in a triangle, so that the top cover on the box body is opened when the electric push rod is extended and the top cover is covered on the box body when shortened. The invention can conveniently open the top cover through the movement of the electric push rod of the cover opening mechanism, especially when the top cover is relatively heavy, the opening of the electric push rod can effectively reduce the labor intensity.

Description

technical field [0001] The invention belongs to the field of box-type equipment, and more specifically relates to a large-scale box-type equipment that needs to be opened with a top cover. Background technique [0002] With the development of storage and transportation, the transportation of some large-scale equipment needs to be hoisted from the top, and the realization of some special equipment functions also needs to be carried out from the top, and the development is part of the realization of product functions, so the technology of opening the cover of large-scale equipment is required. The design of the top cover of large-scale box-type equipment not only meets the relevant structural functions, but also involves lightweight technology, sealing technology and electromagnetic shielding technology. [0003] The realization of the structure and function of the top cover has a lot to do with the weight and rigidity of the top cover design. The good rigidity and strength of...

AI Technical Summary

Problems solved by technology

[0004] Today’s large-scale box-type equipment is getting bigger and bigger, and the weight of the top cover is relatively large. It is troublesome to open it manually, and it is time-consuming and labor-intensive; and some top covers are opened by hydraulic cylinders, but hydraulic cylinders generally need a hydraulic station for supply. Oil requires additional space; and during the use of the hydraulic cylinder, the hydraulic oil is prone to heat, which affects the normal use of the hydraulic cylinder. In addition, when the top cover is often subjected to external loads, the hydraulic cylinder is also vulnerable to impact and damage
