Hoisting device for coal mine roadway

Abstract

The invention discloses a lifting device for a coal mine roadway, relates to the technical field of lifting for a coal mine roadway, and comprises a flatbed trailer, a fixed box arranged in the middle of the top surface of the flatbed trailer, and a bearing plate arranged above the fixed box. There is an electric push cylinder, and the upper part of the cylindrical box is equipped with a jacking mechanism for raising the roadway arch frame; the rear ends on both sides of the bottom surface of the bearing plate are fixedly connected with installation shells, and the installation shells are equipped with limiting components for the arrangement of roadway arch frames; The invention facilitates the separation of the coal mine roadway arch frame placed on the bearing plate through the limiting component, avoiding the deflection of the coal mine roadway arch frame after being placed; through the cooperation of the electric push cylinder with the jacking mechanism and the rotating assembly, it is convenient for the coal mine roadway arch frame to be separated. The arch frame used in the roadway is combined with the lifting operation of rough jacking and fine jacking, and at the same time, it is convenient to carry out the horizontal rotation operation of the arch frame during the fine jacking of the arch frame, which improves the convenience of the arch frame during installation It can effectively improve the working efficiency of the staff when installing the arch frame.

Description

technical field [0001] The invention relates to the technical field of hoisting for coal mine roadways, in particular to a lifting device for coal mine roadways. Background technique [0002] In coal mine production, the same coal seam needs to be divided into multiple working faces for mining. In the process of building a new working face or dismantling an old working face, all fully mechanized mining equipment needs to be disassembled, especially for heavy equipment, each working face There are about 100 frames, so the workload of disassembly and assembly is very large, so a lifting device is required to lift the bracket; [0003] Existing lifting devices used in coal mine roadways are mostly rough jacking operations when lifting U-shaped brackets, and cannot perform horizontal rotation operations on the hoisted arches, requiring manual rotation of the arches. The overall operation not only increases the working intensity of the staff, but also increases the danger of the...

Problems solved by technology

[0003] Existing lifting devices used in coal mine roadways are mostly rough jacking operations when lifting U-shaped brackets, and cannot perform horizontal rotation operations on the hoisted arches, requiring manual rotation of the arches. The overall operation not only increases the working intensity of the staff, but also increases the danger of the staff when installing the arch. At the same time, the existing lifting device is not convenient for the staff to connect the hoisted arch with the coal mine roadway. The top is tightly fitted, resulting in a large gap between the installed arch and the top of the coal mine roadway, so the above problems need to be solved
