Embodiment Construction

[0025] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0026] Such as Figure 1-4 As shown, the present invention is a horizontal hydraulic support for mines, including a support plate 100, a hydraulic cylinder 200 is fixed on the bottom of the support plate 100, the bottom of the hydraulic cylinder 200 is connected to the damping cylinder 300, and the damping cylinder 300 is also connected to the bottom of the pressure cylinder 400. The top of 400 is connected to air pump 500; the top of support plate 100 is provided ...

Abstract

The invention discloses a horizontal hydraulic support for mines, which includes a support plate, a hydraulic cylinder is fixed at the bottom of the support plate, the bottom of the hydraulic cylinder is connected to a damping cylinder, the damping cylinder is also connected to the bottom of a pressure cylinder, and the top of the pressure cylinder is connected to an air pump; in the present invention, Since the hydraulic oil in the hydraulic cylinder under the support plate is connected to each other, according to the principle of the connector, the hydraulic pressure will keep the support plate level at this time, the air pump will inflate the pressure cylinder, and the high-pressure gas will push the hydraulic oil in the pressure cylinder into the sleeve, pushing the first The first piston moves upwards, the air pump reverses, and the gas in the pressure cylinder is pumped out, so that the support plate can be lowered; when vibration occurs, the first piston moves up and down in the sleeve due to the force of the vibration, and presses the hydraulic oil in the damping cylinder. Due to the S-shaped distribution of the damping hole, the hydraulic oil rubs against the inner wall of the damping hole when it passes through, converting the mechanical energy of the vibration into internal energy, and the blocking plate in the damping hole can play a damping role, which can effectively suppress the vibration .

Description

technical field [0001] The invention relates to the field of mine equipment, in particular to a horizontal hydraulic support for mines. Background technique [0002] During the process of mine excavation, because the mining will cause the original stable stratum structure to be damaged, it is necessary to support the mining tunnel to prevent landslides. Due to the large force of the supporting structure, and the soil and rock structure of the tunnel is under stress. Subsidence is prone to occur in the case of mining, which makes the support plate unable to maintain the level, and the vibration generated during the mining process will also cause the support surface to be unstable. [0003] In the patent specification whose publication number is CN102373939B, a kind of short wall working face light hydraulic frame is disclosed. Solve the technical problem that the existing hydraulic support is not suitable for the working face with short wall and large mining height in coal m...
