Abstract
The invention relates to a self-moving hydraulic support, which is used for supporting in time while assisting in a work surface support to retreat and move after the underground coal mine fully mechanized coal mining face finishes coal mining, and belongs to the field of coal mine machinery. The self-moving hydraulic support comprises an external frame top beam and an external frame base in a form with gaps at the middle and rear parts; an internal frame is nested in the gaps of the external frame top beam and the external frame base; and an internal frame base is connected with the external frame base through pushing a jack. The self-moving hydraulic support is used for supporting an empty roof in time when the work surface support retreats, so that the mechanization is realized, the risk of artificially maintaining the roof plate is solved, the labor intensity of workers is reduced, the production efficiency is improved, and a safe operation environment is provided for the workers. The self-moving hydraulic support is used for replacing pointed pillars or timber cribs, and the production cost is reduced.
Description
Technical field
The present invention relates to a kind of self-advancing hydraulic support, be used for the colliery down-hole combined mining working mine finish after, in back work face support removal of home when falling the face, be used for the hydraulic support of immediate support, genus coal mine machinery field.
Background technology
The withdrawing from of fully-mechanized mining working equipment is one and not only taken a lot of work but also time-consuming work.When withdrawing from hydraulic support, support one side is the goaf, the impact that has been subject to mining of the top board above the support, stability is subject to than havoc, thus support withdraw from more complicated.The original way of withdrawing from is: the top board after support is withdrawn from will or be laid grillage and in time safeguard with a post, along with withdrawing from of support, safeguard with some post or grillage and can not all regain, so expense is very large, and the danger when strong point post or laying grillage is also very large.Self-advancing hydraulic support of the present invention is exactly the mechanized equipment of withdrawing from rear immediate support for force piece.
Existing self-advancing hydraulic support structure is the front and back posture, and appearance and size is long, only is applied to colliery tunnel support, can not be used for move temporary lining after when falling the face, hydraulic support was withdrawn from of fully-mechanized mining working.Self-advancing hydraulic support of the present invention is interior outrigger nesting type structure, appearance and size than front and back posture length short half, the temporary lining after being mainly used in fully-mechanized mining working removal of home when falling the face, hydraulic support being withdrawn from.
Summary of the invention
The present invention provides a kind of force piece of realizing to withdraw from the self-advancing hydraulic support of rear timely mechanization supporting in order to address the above problem.
Technical solution is:
Self-advancing hydraulic support of the present invention, formed by support arm, inner support, support arm comprises: outrigger back timber and outrigger base adopt postmedian gap form, and inner support is nested in outrigger back timber and the outrigger base breach, and the internal frame base is connected advancing jack with the outrigger base and connects.
Advantage of the present invention and effect are:
The first, when withdrawing from for force piece, self-advancing hydraulic support of the present invention to empty top immediate support, realized mechanization, solved the danger of manual maintenance top board, alleviate workman's labour intensity, improved production efficiency, the operating environment of a safety is provided for the worker.
The second, self-advancing hydraulic support of the present invention has replaced some post or grillage, has reduced cost of production.
Description of drawings
Fig. 1 is structural representation of the present invention.
The specific embodiment
The present invention is comprised of support arm and inner support.
Support arm of the present invention is comprised of outrigger back timber 1, outrigger caving shield 2, outrigger back link 3, outrigger front rod 4, outrigger base 5, outrigger column 6, outrigger back timber 1 is connected by bearing pin with outrigger caving shield 2, outrigger column 6 respectively, outrigger caving shield 2 is connected by bearing pin with outrigger back link 3, outrigger front rod 4 respectively, outrigger back link 3, outrigger front rod 4 are connected by bearing pin with outrigger base 5 respectively, and outrigger base 5 and outrigger column 6 are connected by bearing pin.
Inner support of the present invention is comprised of internal frame back timber 8, internal frame caving shield 9, internal frame back link 10, internal frame front rod 11, internal frame base 12, internal frame column 13, the internal frame back timber 8 of inner support is connected by bearing pin with internal frame caving shield 9, internal frame column 13 respectively, internal frame caving shield 9 is connected by bearing pin with internal frame back link 10, internal frame front rod 11 respectively, internal frame back link 10, internal frame front rod 11 are connected by bearing pin with internal frame base 12 respectively, and internal frame base 12 and internal frame column 13 are connected by bearing pin.
Outrigger back timber 1 of the present invention and outrigger base 5 adopt postmedian gap form, and internal frame back timber 8 is nested in respectively in the breach of outrigger back timber 1 and outrigger base 5 with internal frame base 12, and internal frame base 12 is connected with the outrigger base by advancing jack 7 connections.
Support arm of the present invention is four post support shield type frame type, and inner support is two posts or four post support shield type frame type; Outrigger back link 3 on the support arm, outrigger front rod 4 adopts the split double link, and internal frame back link 10, internal frame front rod 11 on interior are single connecting rod or double link; Outrigger base 5 is the Integral rigid base.
The present invention is by replacing lifting inner support and support arm roof supporting, and take hydraulic pressure as power, the flexible advancing jack 7 that connects inside and outside bracket base realizes that hydraulic supports are from moving.
Concrete using method: from inside and outside support while support, support arm falls frame with a certain distance from the top (200～300mm), the inner support support is as fulcrum, advancing jack 7 stretches out, support arm is passed a step pitch namely pass very heavy stroke, rise support arm this moment, when support arm connect shore tight after, inner support falls again, advancing jack 7 is regained, drawn inner support to move forward a step pitch, rise the inner support support, self-advancing support has just formed again a complete stent support top board like this, and namely support is finished an operation cycle from moving.
