A height-adjustable arc gate membrane steel support

Abstract

A radial gate forming die steel support adjustable in height comprises a steel support body, wherein the top end of the steel support body is provided with a top base, an ejector rod is arranged below the top base, a transmission device is arranged inside the ejector rod, a casing pipe is arranged outside the ejector rod, a locking device is arranged on the casing pipe, a limit device is arranged inside the ejector rod and located at the upper end of the transmission device, a jacking block is arranged at the lower portion of the transmission device, a locating sleeve is arranged below the jacking block, the transmission device penetrates through the locating sleeve and is connected with a worm wheel and worm below the locating sleeve, the worm wheel and worm is controlled by a rocker to rotate and drive the transmission device, a locating base is arranged at the lower end of the worm wheel and worm, and a base is arranged at the bottom of the steel support body and provided with a connection bolt. By the structure, on the basis of improving the use turnover rate of a radial gate forming die, the erecting efficiency of the radial gate forming die is improved at the same time, and the problem that materials used for erecting of the radial gate forming die are difficult to recycle is solved.

Description

technical field [0001] The invention relates to a device capable of adjusting the size and radius of curvature of an arc-shaped gate leaf by adjusting the number and height of bearing steel supports, in particular to a height-adjustable arc-shaped gate film steel support. Background technique [0002] Since the arc gate is used in different working conditions, the size of the arc gate is also different. The arc surface of the arc gate has a curvature change, so the manufacturer needs to base on its specific size and curvature radius when manufacturing the arc gate. According to the weight of the structure, the arc-shaped membrane of the door leaf that meets the requirements is assembled as a whole. The common practice now is to use steel, steel plate and other materials to set up a special assembled membrane for each size of arc gate, and set a fixed steel support at each supporting point for support. After completion, it can be removed or refitted to accommodate other size...
