Supporting device with protection function for coal mine safety construction

Abstract

The invention discloses a supporting device with a protection function for coal mine safety construction. The supporting device with the protection function comprises a base, a first supporting columnis connected to the base, a second supporting column is arranged on the first supporting column, the first supporting column and the second supporting column are sleeved with sleeves, a top plate isconnected to the end, away from the first supporting column, of the second supporting column, and an upper baffle is arranged in the top plate; and the end, located outside the top plate, of the upperbaffle is connected with a handle, the end, away from the handle, of the top plate is connected with a side baffle, an extension plate is arranged in the side baffle, and cavities are formed in the sleeves and located between the first supporting column and the second supporting column. According to the supporting device, through arrangement of corresponding mechanisms on the coal mine supportingdevice, the supporting device can effectively block soil or stones in a mine during use, the situation that the soil or the stones in the mine fall off to injure workers is effectively reduced, the safety coefficient in the mine is effectively improved, and the possibility of mine collapse caused by falling of a large amount of soil or stones is effectively reduced.

Description

technical field [0001] The invention belongs to the technical field of mine support equipment, and in particular relates to a support device with protective function for safe construction in coal mines. Background technique [0002] Coal mines are areas where human beings exploit coal resources in coal-rich mining areas. They are generally divided into underground coal mines and open-pit coal mines. When the distance to the surface is very short, it is generally chosen to directly strip the surface soil layer to excavate coal. This is an open-pit coal mine, and most of the coal mines in my country are underground coal mines. [0003] When traditional underground coal mines are excavated, they usually use support devices to support the mine. However, the traditional support devices lack corresponding protection mechanisms and cannot effectively block the soil or stones in the mine. Falling soil and stones Blocks are easy to injure workers, there is a big safety hazard, seriou...
