Abstract

The invention discloses a dual-purpose powerful waste edge support for mechanical mining and blasting mining, which comprises a top beam, a top beam side protecting plate, a hydraulic prop, a waste rock baffle, a waste edge balancing oil cylinder, an upper stabilizing rod, a lower stabilizing rod, a base, a pushing oil cylinder, a pushing rod, and the like, wherein the hydraulic prop is supported between the base and the top beam; the waste edge balancing oil cylinder is arranged between the top beam and the base; hydraulic valves are connected to upper and lower cavities of the waste edge balancing oil cylinder; the upper stabilizing rod is connected to the top beam; the lower stabilizing rod is connected to the base; the upper and lower stabilizing rods are box-shaped bodies and are flexibly sleeved; the pushing rod is mounted in the middle of the base; the pushing oil cylinder is connected between the base and the pushing rod; and in the dual-purpose powerful waste edge support, the waste edge balancing oil cylinder, the upper stabilizing rod and the lower stabilizing rod are connected, thereby keeping the support balanced and stable along the longitudinal and vertical directions.

Description

technical field [0001] The invention relates to hydraulic support technology, in particular to the field of coal mining support Background technique [0002] figure 1 It is a structural schematic diagram of an integral roof beam hydraulic support in the prior art. The hydraulic support consists of a front beam 1, a roof beam 2, a guiding and anti-falling moving beam 3, a roof beam moving hydraulic cylinder 4, a roof cutting support beam 5, a cutting beam Top limit device 6, powerful hydraulic prop 7, rear base 8, front and rear base connecting device 9, hydraulic prop 1, front base 11, base moving hydraulic cylinder 12, and push rod 13 are composed. Although this kind of hydraulic support in the prior art reduces the weight of the support and reduces the cost, it still has the following defects: [0003] (1) When the bracket is used on a working surface with a large inclination angle, it is easy to fall due to the pressure of the top plate. [0004] (2) The support struct...
