Description
The present invention relates to a kind of hydraulic machinery equipment, be specifically related to the hydraulic prop system of a kind of mine underground work.
The base of its hydraulic pressure pillar of existing hydraulic prop system is installed in the bottom of pillar hydraulic cylinder body, by hydraulic cylinder bottom be supported on the stope base plate of down-hole, mine, piston rod rises and supports operation, the pillar volume is big, heavy, is unfavorable for the protection of piston rod; The piston of hydraulic pressure pillar and allow to press valve be the partial installation structure; allow and press valve to be installed in the outside of pillar hydraulic cylinder; not only increased the weight of pillar; allow the pressure valve be subjected to down-hole stope blasting impact simultaneously and damage easily, one way valve laterally exposes and is installed on the pillar outside, no valve seat protection; be subjected to the impact failure of shot rock equally easily; so that the hydraulic pressure pillar can't release need remove the time, needs maintenance, changes, and has increased equipment cost.Simultaneously, the water under high pressure that hydraulic prop system injected is provided by a kind of fixed large hydraulic station, and this fixed large hydraulic station structure is complicated heavy, particularly can not carry and move, transfer pipeline is long, cost is high, and energy loss is serious, and underground work is extremely inconvenient.
The present invention's purpose aim to provide a kind of simple and compact for structure, flexible, carry conveniently moving, save transfer pipeline, energy consumption is low, the water source wind regime is gathered materials on the spot, cost is low, make things convenient for underground work, effectively protect the pillar one way valve, allow the hydraulic prop system of pressing valve and piston rod, prolongation service life of equipment, support equipment serviceability rate.
Technical solution of the present invention is: this hydraulic prop system is made up of hydraulic pressure pillar and pneumatic booster water pump, the hydraulic pressure pillar includes base, piston rod, the cylinder seat, piston, piston bush, one way valve, one-way valve seat, the cylinder cap, extension element, hydraulic cylinder, allow the pressure valve, sheath, centring sleeve, base is installed in piston-rod lower end, the piston rod upper end installs and fixes piston, piston bush, allow the pressure valve, and be sleeved in the hydraulic cylinder, hydraulic cylinder and cylinder seat, centring sleeve is connected and fixed, sheath is sleeved on the hydraulic cylinder periphery, the hydraulic cylinder upper end is fixed with the cylinder cap, extension element can be sleeved on cylinder cap upper end, hydraulic cylinder top also is mounted with one-way valve seat, has into drainage channel in the one-way valve seat, opening down, one way valve is vertically mounted in the valve seat; Its structure of pneumatic booster water pump is that inlet suction port is installed in the box cover, oil sprayer and pressure regulator, the gas circuit tube connector, the distribution reversal valve, the double piston-rod cylinder, water supply connector, the water route tube connector, high pressure cylinder, the water under high pressure output pipe, out splice going splice, inlet suction port, oil sprayer and pressure regulator, the gas circuit tube connector, the distribution reversal valve, the double piston-rod cylinder connects successively, water supply connector, the water route tube connector, high pressure cylinder, the water under high pressure output pipe, out splice going splice connects successively, high pressure cylinder has two, divide the both sides that are listed in the double piston-rod cylinder, has into water one way valve in the high pressure cylinder, check valve of water drainage and piston, double piston-rod and big piston are installed in the double piston-rod cylinder, the double piston-rod two ends are connected and fixed with the piston of two high pressure cylinders respectively, the check valve of water drainage output of two high pressure cylinders all connects the water under high pressure output pipe, out splice going splice, out splice going splice connects to the one-way valve seat of hydraulic pressure pillar by pipeline again, the water under high pressure of pneumatic booster water pump is injected in the hydraulic cylinder of hydraulic pressure pillar.
The present invention compares with prior art, owing to base is installed on the bottom of support piston bar, protected piston rod on the one hand, on the other hand, piston rod can be supported on the stope base plate of down-hole, piston rod is motionless, and hydraulic cylinder body rises and supports operation, thereby alleviated pillar rising part weight, effectively improved the speed of shore supports; Again since the present invention with piston with allow and press valve to be assembled into one, all place support piston masthead portion, during use, piston and allow to press valve be non-moving component, only hydraulic cylinder body motion, a column pressure can reach 200KN, when a column pressure surpasses 200KN, press valve to carry out release by allowing of support piston central part, thereby a column pressure is remained at about 200KN.Allow and press valve to be installed on the piston center of pillar, neither can increase the weight of piston, avoided down-hole stope rock blasting to allowing the impact and the damage of pressing valve again, greatly strengthened the shock proof ability of valve of pressing that allows, prolong the application life of pillar, ensured the serviceability rate of equipment and normally carrying out of production operation.Again because the present invention is mounted with downward opening one-way valve seat on the pillar hydraulic cylinder, so, when the hydraulic pressure pillar uses at down-hole, mine stope, though sudden and violent broken rock can impact on the one-way valve seat, but can't impact one way valve, also can not accumulate the rock and the dust of blasting impact, thereby protect one way valve effectively, greatly prolong the application life of one way valve; Pneumatic booster water pump of the present invention is owing to adopted three piston water booster systems to form, big piston is the double piston-rod piston, promote by external compressed air, the valve piston on both sides alternately produces water under high pressure output, the big piston at middle part is fixed on the same axle with the valve piston that is positioned at both sides, so, it is reciprocating that big piston drives the valve piston on both sides simultaneously, make two high pressure cylinders alternately with external low-pressure water pressurization back output, therefore, pneumatic booster water pump compact conformation of the present invention, volume is little, in light weight, light and flexible, carry and move easily, save transfer pipeline, energy consumption is low, water source and wind regime are gathered materials on the spot, and cost is low, make things convenient for underground work.In sum, the present invention is novel, reasonable in design, function admirable, reliable operation, for the stope operation of down-hole, mine provides a kind of novelty, convenience, practical novel device.
