Abstract

The invention discloses a U-shaped shed with a supporting mechanism, and relates to the field of mechanical manufacturing. The U-shaped shed comprises a plurality of telescopic columns, two transverse telescopic columns cooperate with each other, the upper ends of the telescopic columns are movably provided with connecting frames I, the two connecting frames I are symmetrically arranged, a connecting frame II is movably installed at the upper ends of the two connecting frames I, a protective shed is movably installed at the upper ends of the connecting frames I and the connecting frame II, and fastening mechanisms are arranged on the two sides of the joints between of the telescopic columns and the connecting frames I and the two sides of the joints between the connecting frames I and the connecting frame II. According to the U-shaped shed with the supporting mechanism, the distance between supporting columns and connecting columns can be changed, a user can conveniently adjust the height of the telescopic columns, use is convenient, the protective shed can be conveniently replaced by a user, the stability of the U-shaped shed can be improved, operation is easy, the user can conveniently disassemble the U-shaped shed, meanwhile, the assembly is convenient, the time of the user can be saved, and the working efficiency can be improved.

Description

technical field [0001] The invention relates to the field of mechanical manufacturing, in particular to a U-shaped shed with a supporting mechanism. Background technique [0002] U-shaped steel support is a kind of passive support for coal mine support, with high tensile strength and compressive strength, especially in deep complex roadways and soft coal seam roadways. The roadway is mainly based on active and passive combined support, among which U-shaped steel shrinkable supports are widely used, but the open arch structure is not suitable for the stress environment of the full section of the deep well. In this case, the numerical simulation software was used to conduct in-depth research and analysis on the load change law of the U-shaped shed support before and after the anchor bar retaining and the influence on the stability of the surrounding rock of the roadway. The stability of the protection body and the surrounding rock is obviously improved, and the pretightening ...
