Supporting structure for coal mining

Abstract

The invention discloses a supporting structure for coal mining. The supporting structure for coal mining comprises a base, a second hydraulic rod is arranged in the middle of the upper end of the base, an installing plate is arranged at the output end of the second hydraulic rod, the upper end face of the installing plate is provided with an installing groove, and a pressure sensor is arranged atthe bottom of the installing groove; a supporting block is arranged over the installing groove, and an anti-slip layer is arranged on the upper end face of the supporting block; guiding rods are symmetrically arranged on the two sides of the lower end of the supporting block, the lower ends of the guiding rods are slidably sleeved with supporting sleeves, the lower ends of the supporting sleeves are fixedly connected with the pressure sensor, and a plurality of buffering springs are arranged between the lower end face of the supporting block and the pressure sensor; the output end of the pressure sensor is electrically connected with a control panel, a display screen is arranged on the control panel, and therefore the device supporting force can be directly observed; and rotary supportinglegs are symmetrically arranged on the two sides of the lower end of the base, and the upper ends of the rotary supporting legs are rotatably connected with the base. According to the supporting structure for coal mining, the supporting structure is optimized, the defects existing in a traditional device are eliminated, the requirements of people are met, and the practicability is high.

Description

technical field [0001] The invention relates to the technical field of coal mining, in particular to a support structure for coal mining. Background technique [0002] Coal mines are areas where human beings exploit coal resources in coal-rich mining areas, and are generally divided into underground coal mines and open-pit coal mines. When the coal seam is far away from the surface, it is generally selected to excavate the coal by digging the roadway underground, which is an underground coal mine. 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. Therefore, the mining of coal mines is inseparable from the support of support. The support used in traditional coal mining is mostly wood. The ...

AI Technical Summary

Problems solved by technology

Therefore, the mining of coal mines is inseparable from the support of support. The support used in traditional coal mining is mostly wood. The strength of wood compression and bending resistance is relatively weak. Wood is not convenient for the stability of the bottom of the mine, and it is not good In view of this, the patent announcement number CN206816282U discloses a support, but this device is too simple, and cannot be transported, and cannot meet people's needs
