Abstract

The invention discloses an extensible platform based on a hydraulic transmission principle, and particularly relates to a bearing device for driving two sides of a fixed platform to be synchronously and bidirectionally unfolded and folded by utilizing a hydraulic transmission mechanism. The problems that most existing bearing platforms are fixedly arranged and the space is not flexible enough aresolved. The extensible platform comprises a fixed platform, a stand column and a first expansion assembly, wherein the stand column is fixed below the middle part of the fixed platform, a hydraulic cylinder is fixedly arranged on one side of the stand column, an upper part of the hydraulic cylinder is hermetically connected with a piston rod in a sealing manner, the upper end of the piston rod ishinged to the lower end of a connecting rod, and the upper end of the connecting rod is hinged to the first expansion assembly; the first expansion assembly comprises a first movable platform, a firstsliding block, a first guide groove, a first toothed plate and a first gear, wherein the upper end of the connecting rod is hinged to the lower part of the tail end of the first movable platform, a first sliding block is fixed on the upper part of the tail end of the first movable platform, the first slide block is slidably connected in the first guide groove, and the first guide groove is fixedon the lower surface of the fixed platform.

Description

technical field [0001] The invention relates to hydraulic equipment, in particular to an expandable platform based on the principle of hydraulic transmission. Background technique [0002] The bearing platform is very useful in the manufacturing process. For example, in the production of rubber tire molds, the molds of radial tires and all-steel tires are basically completed by split casting. There is a certain shrinkage ratio, therefore, it is determined whether the circumferential angle conforms to the process by putting together a circle, reaching 360 degrees. [0003] At present, most of the existing load-bearing platforms are fixed platforms, and their effective use area is a certain value, which will occupy a large space when not in use. In the process of use, for some large-sized workpieces, the effective area cannot transformation, resulting in too small, therefore, a scalable platform is needed to solve the above problems. Contents of the invention [0004] Base...
