Embodiment Construction

[0019] The core of the present invention is to provide a mine support device, which can achieve a more stable support effect and can support higher structures.

[0020] In order to enable those skilled in the art to better understand the technical solution of the present invention, the mine support device of the present application will be described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0021] like figure 1 Shown, is the front structural view of the mine support device provided by the present invention, figure 2 and image 3 Respectively represent the side view and top view of the mine support device.

[0022] The device includes structures such as a top beam 1, a base 2, and a hydraulic prop 3. The top beam 1 is at the top of the entire device for leaning against the top of the incision, and the base 2 is at the bottom for leaning against the top of the incision. The bottom end acts as a support. The bottom o...

Abstract

The invention discloses a mine support device which comprises a top beam and a base. The top beam and the base are used for abutting against the top end and the bottom end of a cut hole correspondingly. The bottom of the top beam is connected with the telescopic ends of at least two hydraulic stand columns, and the base is connected with hydraulic cylinders of the hydraulic stand columns. Since the at least two hydraulic stand columns are arranged, a stronger supporting effect can be achieved, the supporting effect of the hydraulic stand columns is better, the hydraulic stand columns can be longer, and thus the higher support requirement is met. The tops of the hydraulic stand columns are all connected to the top beam, the bottoms of the hydraulic stand columns are all connected to the base, the larger supporting area is obtained, the more stable supporting effect can be achieved, the supporting stability is higher, and the mine support device has better instability resistance.

Description

technical field [0001] The invention relates to the technical field of mine equipment, and further relates to a mine support device. Background technique [0002] At present, the supporting equipment widely used in the cutting eye of the comprehensive mechanized coal mining face has low strength, poor integrity, and is easy to lose stability and topple over. With the improvement of the technical level of mining equipment in our country, the full-height system of one-time mining in thick coal seams has been widely promoted. The support used in the full-height working face of primary mining has a large frame type and a high height. It is required that the section size and height of the working face and the cutting eye meet the installation requirements of the hydraulic support on the working face. With the gradual depletion of shallow coal in my country, coal mining is gradually shifting to deep mining, where the stress of deep mining is high and the roof pressure is high. I...
