Abstract

The invention discloses a sleeve connection rod type anti-impact bracket. The sleeve connection rod type anti-impact bracket comprises a top beam, a plurality of supporting columns and a bottom beam,two ends of the supporting columns are separately hinged to the top beam and the bottom beam, the top beam is in an arc shape, the supporting columns hinged to the lower part of the top beam are arranged on the top beam in the length direction of the top beam, the supporting columns are of telescopic structures, and the top beam is driven by the supporting columns to enable the top beam move in the limited telescopic direction of the supporting columns. According to the sleeve connection rod type anti-impact bracket, the top beam is arranged as an arc-shaped structure and can better adapt to the sectional shape of an arch roadway, the top beam is supported by depending on the supporting columns with the telescopic structures below the top beam, so that supporting force of the bracket is more balance. Meanwhile, the top beam with the arc structure has good structural strength, optimal structural design of a beam body is facilitated, and the material utilization rate is improved.

Description

technical field [0001] The invention relates to the technical field of coal mining, in particular to a sleeve link type anti-shock bracket. Background technique [0002] Rock burst is one of the most serious dynamic disasters in coal mine production. There are many mines with rock burst in my country. With the increase of coal mine mining depth and the continuous expansion of mining intensity, the damage degree of rock burst is also increasing It is characterized by sudden, sharp and violent failure in the coal and rock mass of the shaft or working face, accompanied by the sudden release of strain energy in the coal and rock mass, which not only affects the mining progress, but also often threatens the mining personnel. and machine safety. [0003] At present, the preventive technology of "strong pressure relief and strong support" is mainly used for rock burst roadways, which cannot truly realize long-term support for the roof in coal mine roadways, and reduce or solve disas...
