Rotating platform for support installation

Abstract

The invention relates to the technical field of coal mining and discloses a rotating platform for support installation. The rotating platform comprises a base and a rotating seat, the rotating seat isconnected to the base through rotation, linking guide rails are arranged on the rotating seat, front pushing mechanisms are connected to the linking guide rails, rotating shafts are arranged beside the linking guide rails, movable car stoppers are arranged on the rotating shafts, the movable car stoppers and the rotating shafts are fixed in the circumferential direction and are in sliding fit inthe axial direction, fixed car stoppers are arranged at the other ends, opposite to the movable car stoppers, of the linking guide rails, the front pushing mechanisms are connected with the movable car stoppers, rotation driving mechanisms are connected to the rotating shafts, and the movable car stoppers are located beside the linking guide rails in an opening state and located on the rail surfaces of the linking guide rails to be transformed into a car stopping state when the movable car stoppers are driven to rotate by the rotating shafts. The rotating platform is used for supporting installation of a comprehensive mechanized coal mining face and can effectively improve the installation efficiency of movable pulleys, improve construction safety and reduce accident risks.

Description

technical field [0001] The invention relates to the technical field of coal mining, in particular to a rotating platform for bracket installation. Background technique [0002] The traditional installation method of the fully-mechanized mining face support is horizontal installation, that is, the length direction of the fully-mechanized mining face support enters the cutting eye in the direction perpendicular to the cutting eye axis, and finally reaches the bracket installation place along the cutting eye. The horizontal installation of the support in the fully mechanized mining face has the advantages of simple installation process and convenient lowering of the support. Since the support length of the fully mechanized mining face is about 7 meters, the horizontal installation of the cutting guide aisle needs to be opened at one time. . In the process of coal mining, it is often encountered that the distance between the mining coal seam and the overlying coal seam is rela...

Problems solved by technology

Among them, the rotating platform is a very critical equipment in the bracket installation method. Although it can be manufactured with reference to the existing rotary platform, the existing rotary platform is not designed for the installation and transportation of the bracket. Therefore, it is difficult to safely and quickly remove the bracket from the The track of the level road is transferred to the track of the cut-out guide tunnel
