Abstract

The utility model provides a portable single pillar dust-proof water booster pump for mine, belonging to the booster pump, comprising a single pillar oil cylinder, a boosting cylinder, an operation valve, an emulsion liquid box, a first check valve, a second check valve and a third check valve, wherein the boosting cylinder comprises an A cavity, a B cavity and a C cavity and the lower end of the single pillar oil cylinder is simultaneously connected with a No.1 output port of the operation valve and an A cavity port of the boosting cylinder by the second check valve; and simultaneously the lower end of the single pillar oil cylinder is connected with the C cavity of the boosting cavity by a third check valve and connected with the emulsion liquid box by the first check valve; a No.2 output port of the operation valve is connected with the B cavity of the boosting cylinder and a No.3 port and a No.4 port of the operation valve are input ports. The advantages of the utility model are that: (1) the structure is simple and the booster pump is conveniently operated; (2) the boosting speed is quick and the boosting effect is obvious; (3) the emulsion liquid is injected into the single body to prevent the single oil cylinder from being corroded, so as to prolong the service life of the single oil cylinder; (4) after accomplishing the work, the residual dust-proof water is used for making the dust fall on the work surface and the work environmental quality is increased.

Description

The portable mine individual pillar water suction booster that prevents dust

Technical field

The utility model relates to a kind of increase pump, particularly a kind of portable mine individual pillar water suction booster that prevents dust.

Background technique

In colliery down-hole coal excavation, tunneling process, along with coal mining, driving progress are constantly extended, gradually away from pumping plant, pumping plant is also along with the working surface gradation is moved forward with individual prop in supporting.And for some fragmentary engineerings, as repairing the tunnel, using prop drawer that situations such as electricity strand are installed, if install or move pumping plant, it is time-consuming to require great effort, and has wasted manpower and materials, and the utilization efficiency of pumping plant is low simultaneously.Therefore, at present, in the repair process of tunnel, generally be to adopt manual point of safes post to suppress, but the setting pressure that manual point of safes post is suppressed can not guarantee that using effect is poor, therefore for a long time, the top casualty accident that falls of boring head is not effectively controlled all the time, has brought trouble for the colliery safety control.

The model utility content

The purpose of this utility model is to provide a kind of: the dustproof water suction booster of portable mine individual pillar that can guarantee setting pressure when suppressing.

The purpose of this utility model is achieved in that this suction booster comprises individual prop oil cylinder, pressurized cylinder, operating valve, emulsion box, first one-way valve, second one-way valve and the 3rd one-way valve, pressurized cylinder has three cavitys, be respectively A chamber, B chamber and C chamber, the lower end of individual prop oil cylinder is connected with No. 1 output port of operating valve and the A chamber port of pressurized cylinder simultaneously by second one-way valve; Also is connected with the C chamber of pressurized cylinder by the 3rd one-way valve simultaneously and reach passes through first one-way valve and be connected with emulsion box, No. 2 output ports of operating valve are connected with the B chamber of pressurized cylinder, and No. 3 of operating valve and No. 4 ports are input port.

Beneficial effect, owing to adopted such scheme, in away from the pumping plant tunnel, need gib, or situation such as when prop drawer being installed making the electricity consumption strand, the dustproof water suction booster of mine individual pillar is suppressed interim individual prop or prop drawing column by pressurized cylinder, is pressurized to setting pressure up to specification, can guarantee setting pressure when suppressing, ensure the hydraulic equipment proper functioning, can reduce, can increase work efficiency because of moving the manpower and materials waste that pumping plant brings, promote project progress, guarantee safe production.Simultaneously, in the process of supercharging, can give again and inject a certain amount of emulsified liquid in the individual prop chamber, can prevent the monomer corrosion, promote to lubricate, increase the service life.Reached the purpose of this utility model.

Advantage: (1) is simple in structure, and is easy to operate.(2) supercharging is fast, and effect is obvious.(3) emulsified liquid is injected in the monomer, can protect the monomer oil cylinder not to be corroded, and can prolong the working life of monomer oil cylinder.(4) in operating process, utilize dustproof water pressure to be provided for hydraulic equipment away from pumping plant by pressurized cylinder pressurization back, unnecessary dustproof water can be used for the working surface depositing dust after work was finished, and improved the working environment quality.

Description of drawings

Fig. 1 structural drawing of the present utility model.

Among the figure, 1, the individual prop oil cylinder; 2, pressurized cylinder; 3, operating valve; 4, emulsion box; 5, first one-way valve; 6, second one-way valve; 7, the 3rd one-way valve.

Embodiment

Embodiment 1: this suction booster comprises individual prop oil cylinder 1, pressurized cylinder 2, operating valve 3, emulsion box 4, first one-way valve 5, second one-way valve 6 and the 3rd one-way valve 7, pressurized cylinder has three cavitys, be respectively A chamber, B chamber and C chamber, the lower end of individual prop oil cylinder is connected with No. 1 output port of operating valve and the A chamber port of pressurized cylinder simultaneously by second one-way valve 6; Also is connected with the C chamber of pressurized cylinder by the 3rd one-way valve 7 simultaneously and reach passes through first one-way valve and be connected with emulsion box, No. 2 output ports of operating valve are connected with the B chamber of pressurized cylinder, and No. 3 of operating valve and No. 4 ports are input port.

Working principle: utilize the mine dustproof water making operation valve 3 of hydraulic pressure for 3-4MPa.

The first step: when the control valve handle is beaten in right position, dustproof hydraulic pressure injects 3-4MPa pressure for the monomer cavity of resorption by valve block → second one-way valve → fluid injection, monomer extend out to top board and connects the top, dustproof simultaneously hydraulic pressure is given piston cavity A feed flow: owing to there are gap in A chamber, B chamber piston area, piston rod is passed to the B chamber, and the C chamber forms vacuum simultaneously, the 3rd closed check valve, first one-way valve communicates with the emulsified liquid that is equipped with 10%, and first one-way valve opens sucks naturally and contains 10% emulsified liquid and enter in the C chamber.

Second step: when the control valve handle is beaten left the position, dustproof water with 3-4MPa is by plate valve → piston cavity B, because the ratio of piston B and piston cavity C area is 4.6: 1, because piston cavity B pressure is 3-4MPa (ore deposit prevent dust hydraulic pressure), so the piston cavity C internal pressure rises to 14-18MPa.The 3rd one-way valve opens, first one-way valve and second closed check valve, high-pressure emulsion from piston C chamber enters filling gun, filling gun injects the emulsified liquid of 14-18MPa for for the second time the monomer cavity of resorption, monomer oil cylinder internal pressure increases, reach the setting pressure of monomer work, monomer gets final product proper functioning, thereby has reached the purpose of giving the individual prop supercharging.
