Abstract

The invention provides a hydraulic lifting device for mining. The hydraulic lifting device comprises a hydraulic lifting substrate, wherein a bearing panel is connected with and fixedly mounted at thetop of the hydraulic lifting substrate through rivets and other structures; the edge of an elastic blanket net is fixedly connected with the interior of the bearing panel through clamping hooks, viscose and other structures; reinforcing platforms are connected with and fixed at four corners of a bottom base of the hydraulic lifting substrate through welding; and independent hydraulic columns areconnected with and mounted at the tops of the reinforcing platforms through threaded structures. Through the arrangement of the reinforcing platforms and the bearing panel, the problem that the surface structure of a conventional hydraulic lifting device is not specialized to a certain extent aiming at part of the mining requirements, for example, the phenomenon about the falling of several soil blocks often occurs in a mine and the top area of the conventional structure is not enough for more comprehensive protection can be solved.

Description

technical field [0001] The invention belongs to the technical field of mining equipment, and more specifically relates to a hydraulic jacking device for mining. Background technique [0002] Hydraulic jacking device, also called hydraulic jacking mechanism, is a commonly used lifting structure in construction and mechanical operations. [0003] For example, the application number: 201721654670.0, a new type of hydraulic jacking device, the present invention discloses a new type of hydraulic jacking device, which is characterized in that it includes a rectangular bottom bracket, and two long sides corresponding to the bottom bracket are provided with chutes , one short side of the bottom bracket is provided with a hydraulic cylinder, the output shaft of the hydraulic cylinder is connected with a drive link, the two ends of the drive link are provided with sliders, the sliders are located in the chute and can slide along the The length direction of the groove moves, and the d...
