Hydraulic support base

Abstract

The invention relates to a hydraulic support base. The hydraulic support base comprises a main reinforcement and two groove bodies defined by base plates. The main reinforcement comprises internal main reinforcement bodies and external main reinforcement bodies, an attached plate is arranged on the position, corresponding to a connecting hole of a connecting rod, of the internal side of the main reinforcement, and a reinforcing plate is arranged on the position, corresponding to a pillar nest, of the external side of the main reinforcement. The internal main reinforcement bodies and the external main reinforcement bodies are connected through a first horizontally-arranged cover plate, the adjacent internal main reinforcement bodies are connected through second obliquely-arranged cover plates, and a third obliquely-arranged cover plate connected with a gap bridge is arranged on the pillar nest and connected with the internal main reinforcement bodies and the external main reinforcement bodies. A second reinforcement plate is arranged outside the internal main reinforcement bodies in the length direction of the internal main reinforcement bodies, and a lifting lug is arranged on the second reinforcement plate. According to the hydraulic support base, by arranging the attached plate and the reinforcing plate on the main reinforcement, the strength and the anti-bending and anti-torque capacities of the hydraulic support base are improved, the stressed area of the base is increased, the overall length of the base and the length of a sidewalk are increased, the overall height of the hydraulic support base is decreased, and the hydraulic support base is suitable for exploitation of a thin coal seam.

Description

technical field [0001] The invention belongs to the technical field of hydraulic supports, in particular to a hydraulic support base. Background technique [0002] Hydraulic support is a kind of equipment commonly used underground. my country is rich in coal resources, fully mechanized mining equipment is mature, and coal mining technology is becoming more and more perfect. Due to the low production efficiency of thin coal seams and medium and thick coal seams, and the large working resistance of hydraulic supports, many enterprises do not pay attention to thin coal seams and medium and thick coal seams. Production, resulting in a serious waste of many thin coal seam coal resources. With the gradual reduction of coal resources in thick and medium-thick coal seams, many coal mines have begun to pay attention to the mining of thin coal seams. [0003] With the continuous mining of thin coal seams, the working resistance required by the thin coal seam hydraulic support continu...
