Problems solved by technology

[0003] 1. Most of the hydraulic supports used in coal mines are two-column or four-column type, with large lateral size and heavy weight, which brings difficulties to installation and transportation, especially small wellheads and narrow roadways cannot pass through at all, so they have to be dismantled and assembled underground. quite troublesome
[0004] 2. The middle part of the support base is a fully open crotch or half open crotch structure, which has low rigidity and high pressure to the floor.
[0005] 3. The pushing mechanism adopts short push rod + forward push jack or long push rod + reverse push jack, which has complex structure and high manufacturing cost

Abstract

The invention provides a single stand column dual-moving hydraulic support, a moving mechanism and a moving method. The support comprises a top beam, a base, a stand column and a support stabilizing mechanism. The stand column is one in number. The lower end of the stand column is connected with the base, and the other end of the stand column is connected with the top beam or the support stabilizing mechanism. The two sides of the stand column are provided with moving lug shafts. A distributing mode of the moving lug shafts is divided into a front form A and a rear form B, and a moving jack A and a moving jack B are connected and pushed and moved. Compared with the prior art, the support has the advantages that the single stand column is arranged, a crotch opening of the base is avoided, a push rod is avoided, the overall size is small, and the weight is light.

Description

technical field [0001] The invention relates to a single-column double-moving-fluid hydraulic support, a pushing mechanism and a pushing method. Background technique [0002] At present, the hydraulic supports used in coal mines have the following problems: [0003] 1. Most of the hydraulic supports used in coal mines are two-column or four-column type, with large lateral size and heavy weight, which brings difficulties to installation and transportation, especially for small wellheads and narrow roadways, so they have to be dismantled and assembled underground. Quite troublesome. [0004] 2. The middle part of the support base is a fully open crotch or half open crotch structure, which has low rigidity and high specific pressure to the floor. [0005] 3. What the pushing mechanism adopts is all short push rod+forward push jack or long push rod+reverse push jack, the structure is complicated, and the manufacturing cost is higher. Contents of the invention [0006] ...
