Description
Technical field
The utility model relates in a kind of coal mining the support that supporting roof was used when mine room and pillar mining work plane reclaimed coal column, and specifically a kind of is in the room and pillar mining system, is used for the special hydraulic support of Pillar Recovery.
Background technology
The room and pillar mining system is adopted in basin, Erdos, Inner Mongolia Autonomous Region more, the room of only the digging up mine post of not mining, and coal recovery rate is about 30%, and large quantities of coal columns is left under the mine, has caused the significant wastage of coal resources.Common colliery longwall face support can utilize transporter-scraper-trough conveyer when the supporting of down-hole, realize trying to stop people from fighting each other-pushing and sliding-move the stages of mining of frame, and down-hole top board and coal wall caving are carried out supporting.In the room and pillar mining system, there are not any facilities such as transporter-scraper-trough conveyer under the coal mine, so the used various types of comprehensive mining hydraulic brackets of common mine longwall face can't use at the Pillar Recovery work plane.At this phenomenon, for improving the development and utilization of coal resources, the protection ring environment pollution is opened up and is saved these large quantities of abolishment mines, develops at room and pillar mining system Pillar Recovery technology.
Summary of the invention
The purpose of this utility model is: when the room and pillar mining work plane reclaims coal column, provide a kind of original coal column supporting roof that is used for replacing, the special hydraulic support of control coal wall caving.This hydraulic support self do not need transporter-scraper-trough conveyer etc. any auxiliary move to set up execute, just can realize support oneself move, straight line moving or function such as shallow turn.Effectively control coal cinder, spoil improve work efficiency, guarantee the supporting security reliability, the Pillar Recovery special hydraulic support of protection personnel and device security.
The utility model is achieved in that gauche form Pillar Recovery special hydraulic support, protects jack, transmission device, accent frame jack, both sides overhead gage, both sides lower baffle plate etc. by back timber, caving shield, connecting rod, base, column, face guard, wall supporting jack, left and right sides backplate, side and forms; Its main points are: back timber is connected by bearing pin, backing pin with caving shield, and caving shield one end is connected by bearing pin, backing pin with connecting rod with back timber, the other end; Connecting rod one end is connected by bearing pin, backing pin with base with caving shield, the other end; The column two ends are connected by bearing pin, baffle plate with back timber, base respectively; Face guard adopts bearing pin, backing pin to be connected with back timber by the wall supporting jack; The left and right sides backplate protects jack with back timber by side and adopts bearing pin, backing pin to be connected with back timber; Transmission device is by fixing with the inboard welding of the base of two independent small racks; Adopt bearing pin, backing pin, connect, install, two independent small racks are connected, are fixed together and formed the big support of an integral body; Transfer the frame jack to be connected with base by bearing pin, baffle plate, the both sides overhead gage adopts bearing pin, bolt to be connected with back timber, and the both sides lower baffle plate adopts bearing pin, bolt to be connected with base.
The utility model has designed two left and right independent small racks.These two independent small racks are according to the required pressure difference of down-hole top board, and the not equal real current situation of exploitation face roof height can adopt 8 to 2 columns.The also column that can adopt cylinder diameter to differ in size.Yet can adopt the column of differing heights.Number, size, height according to column are different, and put, the difference of installation site, to steel construction piece in this support respond improvement, innovate, be designed to rectangle, rectangle, right-angled trapezium, etc. two independent small racks that structure is identical or structure is inequality of dissimilar support frame type.And above-mentioned two independent small racks are linked together the big support that forms a whole by transmission device.This support has satisfied the required pressure difference of each colliery underground mining face roof fully, and exploitation face roof height is the demand of equal real current situation not.
The utility model hydraulic support central post can adopt single stretching structure or two stretching structure form according to the support height difference.According to the different real current situation of the required pressure of down-hole top board, can adopt 8,7,6,5,4,3 even 2 columns.The also column that can adopt cylinder diameter to differ in size.Yet can adopt highly different columns.
The utility model hydraulic support bracket base leading section or rearward end innovative design two-way or unidirectional accent frame jack device.This is transferred in frame jack device can be according to the structure situation of bracket base, be provided with a folk prescription to or the accent frame jack of two twocoueses.This accent frame jack stroke can reach 400mm～1300mm.When the trip can't satisfy down-hole blast mining face needs sometimes, strengthen the stroke of transferring the frame jack for remedying, adopted in the cylinder body chassis outer side face of transferring the frame jack, the method for having welded a branch sleeve again.After transferring the frame jack sometimes when the haul distance of underground mining work plane is not enough, adding the extension spray lance of different length as required, just can strengthen the stroke of accent frame jack artificially, satisfy the needs of underground mining work plane.Adjust the horizontal shift position of support easily, overcome and avoid the generation of support deviation phenomenon.Can realize the function that support advances, retreats and shallows turn.
The utility model hydraulic support is according to the demand of underground mining face roof control top area size, in the innovative design of set cap two sides the left and right side backplate, strengthen the control top area.This left and right side backplate bilateral or one-sided operation is at any time according to demand played supporting roof, guarantees personnel's safety of walking.Also can put down at any time according to demand, protective cradle plays retaining coal, the effect of retaining cash.The left and right little back timber of this hydraulic support partly can be whole back timber, also can adopt and set up face guard form of structure, strengthens the control top area.
The utility model hydraulic support, front, the and arranged on left and right sides face at support designed independent, general spillplate again, prevents that coal cinder enters in the support in the coal pillar mining process.Can improve the supporting reliability greatly like this, reduce resistance, guarantee quick, linear running, the security reliability of protection personnel and equipment.
The utility model hydraulic support, be by to improve, left and right two independent small racks after the innovation, and associated transmission device fixing, connect, assembling, realized: this hydraulic support self do not need transporter-scraper-trough conveyer etc. any auxiliary move to set up execute, just can reach support oneself move, straight line moving or function such as shallow turn.When the room and pillar mining work plane reclaims coal column, be used for replacing original coal column supporting roof, the special hydraulic support of control coal wall caving.Effectively control coal cinder, spoil have satisfied the exploitation requirement of Pillar Recovery work plane.
