Abstract

The invention discloses an umbrella-shaped point pillar type temporary support for a coal mine roadway. The umbrella-shaped point pillar type temporary support comprises a base, first buffer rods arefixed to the bottom of the base, and fixed panels are fixed to the bottoms of adjusting blocks; a fixed rod is fixed to the upper portion of the base, a second connection rod is connected with the upper portion of a first connection rod, and connection blocks are fixed to the outer side of a nested block; adjusting rods are connected with the interiors of the connection blocks, sliding grooves areformed in the outer sides of the adjusting rods, and fastening blocks are connected with the bottoms of limit rods; a supporting groove is formed in an umbrella-shaped supporting panel, a first connection panel is connected with the right side of the umbrella-shaped supporting panel, and a second connection panel is connected with the right side of the first connection panel. The umbrella-shapedpoint pillar type temporary support for the coal mine roadway is convenient to mount and fix, the supporting area can be effectively adjusted, and the temporary support can be effectively and stably fixed at a suitable position.

Description

technical field [0001] The invention relates to the technical field of coal mine roadways, in particular to an umbrella-shaped point column type temporary support for coal mine roadways. Background technique [0002] In the process of underground coal mining and production in coal mines, the quality of its support is related to the service life and service effect of the roadway. Although certain safety measures have been taken for the temporary support of the underground tunneling roadway in coal mines, and certain results have been achieved, but Due to the shackles of uncertain factors such as variable geological conditions in underground roadways, there are still certain potential safety hazards. Therefore, people's requirements for umbrella-shaped point-column temporary support for coal mine roadways will be more stringent; [0003] However, the common umbrella-shaped point-column temporary support used in coal mine roadways is not easy to install and fix, and cannot effe...
