Abstract

The invention discloses a support for a coal mine. The support comprises a top beam track and a base track. An upper guide wheel is arranged on one side of the top beam track. An upper drive wheel is arranged on the other side of the top beam track. A lower guide wheel is arranged on one side of the base track. A lower drive wheel is arranged on the other side of the base track. Hydraulic uprights are arranged between the top beam track and the base track. A four-bar linkage device is installed in the middle positions of the hydraulic uprights. Rotary shafts are arranged in the middle of the four-bar linkage device. The support can be flexibly used in coal mining, the coal mine can be conveniently supported in explosion, safety of workers and the coal mine in the mining process is guaranteed, the automation degree is high, stability is high, cost is low, practical performance is good, expansibility performance is excellent, design is novel, a good creative scheme is raised, and the support has great market popularization prospects.

Description

technical field [0001] The invention relates to the technical field of coal mines, in particular to a support used in coal mines. Background technique [0002] A coal mine is a reasonable space excavated by humans when excavating geological layers rich in coal, usually including roadways, shafts, and mining faces. Coal is the main solid fuel and a kind of combustible organic rock. It is formed by the luxuriant plants growing in a certain geological age, gradually accumulating into thick layers in a suitable geological environment, and buried in the bottom of the water or in the sand, and formed after a long geological age of natural coalification. Among the various geological periods in the world, the Carboniferous, Permian, Jurassic and Tertiary strata produced the most coal and were important coal-forming ages. The carbon content of coal is generally 46-97%, brown to black in color, with dull to metallic luster. According to the degree of coalification, coal can be div...
