Supporting frame used for mine

Abstract

The invention discloses a supporting frame used for a mine. The supporting frame used for the mine comprises a supporting base. An arc-shaped supporting plate is fixedly connected to the upper surfaceof the supporting base. Inserting grooves are formed in the lower surface of the supporting base, and threaded cylinders are movably connected into the inserting grooves; and threaded rods are in threaded connection with inner sides of the threaded cylinders, connecting rods are fixedly connected to one sides of the threaded cylinders, and supporting blocks are fixedly connected to the lower surfaces of the threaded rods. According to the supporting frame used for the mine, the threaded rods and the threaded cylinders are arranged, because the height of different places in a mining hole is not necessarily the same, staff can adjust the height of the device by rotating a grip to adapt to the height of the mine, and the arc-shaped supporting plate is tightly attached to the mine to achievethe purpose of supporting; through the arrangement of inserting holes, device bodies can be tightly connected in pairs through supporting rods, and a better protection effect is achieved; and the device can be detached and is easy to carry, and the supporting frame used for the mine can be conveniently installed in the small mine by the staff.

Description

technical field [0001] The invention relates to the technical field of mining, in particular to a support frame used in mines. Background technique [0002] Mines include coal mines, metal mines, non-metal mines, building materials mines and chemical mines, etc. Mine scale (also known as production capacity) is usually expressed by annual output or daily output. Annual output is the amount of ore produced by the mine each year. According to the size of the output, it is divided into three types: large, medium, and small. The size of the mine depends on the The economical and reasonable service life of the mine is suitable. Only in this way can the infrastructure cost be saved and the cost reduced. [0003] In the process of mine production, the mining operation consumes the most manpower, material resources, and capital, and is the production link with the greatest potential to reduce mining costs. The main way to reduce mining costs is to improve labor productivity and pro...

[0003] In the process of mine production, the mining operation consumes the most manpower, material resources, and capital, and is the production link with the greatest potential to reduce mining costs. The main way to reduce mining costs is to improve labor productivity and product quality, and reduce material consumption. Usually mines The support frame used is difficult to carry, inconvenient to install, and the support effect is not good
