Heaving floor anchor protection multifunctional drill wagon for coal mine

Abstract

The invention discloses a bottom drum anchor protection multifunctional drilling rig for coal mines, which belongs to the field of coal mine machinery; the technical problem to be solved is to provide a floor drum anchor protection multifunctional drilling rig with simple structure, high degree of mechanization and fast cleaning speed car; the technical solution adopted to solve this technical problem is: a multifunctional drilling rig with bottom drum anchor protection for coal mines, including a frame, a traveling part, drilling rig parts, hydraulic parts, and electrical parts. The front and rear of the frame are symmetrically equipped with a lifting device, and the lifting device is equipped with a rotary traverse device. The rotary traverse device is connected with the drilling rig components. The hydraulic components and electrical components are arranged at the rear of the frame. It is symmetrically arranged on the left and right sides of the bottom of the frame, the frame is provided with an operation table, and legs are provided on both sides of the frame; the invention can be widely used in the field of coal mine machinery.

Description

Technical field [0001] The invention relates to a bottom drum anchor protection multifunctional drill carriage for coal mines, which belongs to the technical field of coal mine machinery. Background technique [0002] When the coal mine roadway has not been mined after the excavation is completed, the bottom surface of the roadway is subject to various stresses, often severe bulging, deformation, or floor heave. The force of the roadway floor and the overall force of the roadway are affected by the direction, size, and floor pressure. The transmission direction, surrounding rock properties, compressive strength and other factors are related. Usually the reason for the floor heave of the roadway is the soft surrounding rock of the floor. When the lateral pressure is large, the pressure is transmitted from the two sides to the floor. The soft floor cannot withstand the large pressure and deforms. In addition, the roadway affected by mining moves ahead due to the mining The impact ...

AI Technical Summary

Problems solved by technology

Usually, the bottom of the roadway is caused by the soft surrounding rock of the floor. When the side pressure is large, the pressure is transmitted from the two sides to the floor. The floor is soft and cannot bear the large pressure and deforms. In addition, the roadway affected by mining is moved ahead of the mining. Under the influence of supporting pressure or in the roadway in the support pressure boosting area of ​​the coal wall, floor heaving often occurs when the floor is relatively hard. The common floor heaving is about 1.5 meters high and 1.5~2 meters in diameter. The floor heaving will cause The section of the roadway is reduced, hindering the transportation and pedestrians, and hindering the ventilation of the mine, so many mines have to invest a lot of manpower and material resources to do the work of digging the bottom, which will seriously lead to the scrapping of the entire roadway, which will have a great impact on the production and safety of the mine. Large constraints seriously affect the excavation work of the next working face

At present, the bottom drum is mainly broken by hand with the help of simple tools, and then the broken coal and rock are loaded on the belt conveyor for cleaning. Therefore, the cleaning speed of the bottom drum is slow with the current process, and the labor intensity of the workers is high, which consumes manpower.
