Problems solved by technology

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 coal mining in thin coal seams and medium-thick coal seams, and the large working resistance of hydraulic supports, many enterprises do not pay attention to coal mining in thin coal seams and medium-thick coal seams. production, resulting in a serious waste of many thin coal seam coal resources

Embodiment 1

[0030] like Figure 1-6 As shown, a hydraulic support base includes two tanks 1 surrounded by main ribs and a bottom plate 12 , and the two tanks 1 are connected by bridges 4 . The tank body 1 is provided with a connecting rod connecting hole 22 and a column socket 6, which are respectively used to connect the connecting rod of the hydraulic support and the hydraulic jack. Since the stress at the connecting rod connecting hole 22 is the most concentrated, the inner side of the main rib corresponds to The connecting rod connecting hole 22 is provided with a sticking plate 7 for reinforcement. The outer side of the main rib is provided with a reinforcing plate 9 corresponding to the column socket 6, and the reinforcing plate 9 is provided with a hanging block 20 for connecting the oil tank pipeline. The inner side of the main rib is located above the column socket 6 and a valve plate 23 , for connection to the valve.

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, and in particular relates to a hydraulic support base. Background technique [0002] Hydraulic support is a commonly used equipment in 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 coal mining in thin coal seams and medium-thick coal seams, and the large working resistance of hydraulic supports, many enterprises do not pay attention to coal mining in thin coal seams and medium-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 coal seams 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 thin...
