Abstract
The invention discloses a bottom adjusting mechanism for a fully mechanized coal mining face hydraulic bracket. The bottom adjusting mechanism comprises a bracket base; guide rods and jacks are respectively transversely arranged at the front part and the back part of the bracket base; the front guide rod and the back guide rod are respectively arranged inside a guide groove in a sliding manner; the movable ends of the front jack and the back jack and one ends of the front guide rod and the back guide rod respectively extend out from the lateral wall of the bracket base, and then are hinged with a bottom adjusting beam which is vertically arranged; and the front jack and the back jack are respectively communicated with a hydraulic pump station through corresponding liquid supply pipelines and operation valves. The bottom adjusting mechanism provided by the invention has the advantages that the mining face bracket is actively prevented from falling and sliding, and the bracket rapidly moves, so that the mining face rapidly propels, and the production efficiency is improved.
Description
Technical field
The present invention relates to fully-mechanized mining working surface hydraulic support, especially relate to fully-mechanized mining working surface hydraulic support and transfer end mechanism.
Background technology
Fully-mechanized mining working is large-inclination-angle coal bed more than 25 ° to occupy sizable proportion, and coal bed texture is complicated, the exploitation difficulty is large, poor stability, economic benefit is not good enough, is the difficult point of coal mining.When the work plane inclination angle is larger, the tangential component of overlying rock face increases, normal component along perpendicular slice reduces, roof and floor strengthens along the slippage of aspect, so that the vertical load that working surface hydraulic support is subject to is less, and suffered lateral force strengthens, cause the hydraulic support bad stability, thereby the downslide that causes hydraulic support with topple over, reduce coal production, cause potential safety hazard.For safety, the reliability that improves the mechanical coal mining of comprehensive mechanized coal mining high_dipping face, need a kind of active anti-skid mechanism that realizes being different from conventional passive anti-skid, but yet there are no all relevant reports.
Summary of the invention
The object of the invention is to provide a kind of fully-mechanized mining working surface hydraulic support to transfer end mechanism, to improve safety, the reliability of the mechanical coal mining of comprehensive mechanized coal mining high_dipping face.
For achieving the above object, the present invention takes following technical proposals:
Fully-mechanized mining working surface hydraulic support of the present invention is transferred end mechanism, comprises bracket base, is horizontally arranged with respectively guide peg and jack at the forward and backward position of described bracket base, and described forward and backward guide peg is slidingly arranged in respectively in the gathering sill; One end of the movable end of described forward and backward jack and forward and backward guide peg extends respectively the sidewall of bracket base and transfers beam to be hinged with the end that longitudinally arranges; Forward and backward jack respectively feed liquid pipeline and the control valve by separately is connected with hydraulic power unit.
It is whole box-structure that beam is transferred at the described end.
The invention has the advantages that along being horizontally installed on guide peg and the jack at the forward and backward position of described bracket base, and be hinged on the end that described forward and backward jack movable end and forward and backward guide peg one end longitudinally arrange and transfer beam; Therefore, can be flexible according to the mining face under mine actual condition, handle respectively or simultaneously the flexible of forward and backward jack, by transferring beam to the independent or whole end regulation and control system of the forward and backward position of bracket base in the end, the fast moving of realization and support anti-down, anti-skidding to the active of force piece reaches the quick propelling of work plane, the purpose of enhancing productivity.
Description of drawings
Fig. 1 is structural representation of the present invention.
Fig. 2 is the A section enlarged drawing of Fig. 1.
Fig. 3 is the schematic diagram of transferring three kinds of duties of beam in the end of the present invention.
The specific embodiment
As shown in Figure 1, 2, 3, fully-mechanized mining working surface hydraulic support of the present invention is transferred end mechanism, comprise bracket base 1, be horizontally arranged with respectively guide peg and jack at the forward and backward position of described bracket base 1, in described forward and backward guide peg 2,3 gathering sills that are slidingly arranged in respectively separately; Described forward and backward jack 4,5 movable end and forward and backward guide peg 2, an end of 3 extend respectively the sidewall of bracket base 1 and are hinged with transferring beam 6 at the bottom of the whole box-structure that longitudinally arranges; Forward and backward jack 4,5 respectively feed liquid pipeline and the control valve by separately is connected with hydraulic power unit.
Claims (2)
