Abstract
A single hydraulic prop capable of prevent a valve from flying out comprises a top cover (1), a movable prop body (2), a connecting valve base (3), a combined seal ring (4), a handle body (5), an oil cylinder (6), a piston (7), a return spring (8), a prop protective sleeve (9), a base (10), a round baffle plate (11), two release prevention U-shaped clamps (12), a three-way valve (13) and a valve base (17) thereof, and so on. The valve base (17) of the three-way valve is arranged on the connecting valve base (3). The handle body (5) is arranged below the connecting valve base (3) and can flexibly rotate. Two annular grooves are machined inside the two ends of the three-way valve in the proper positions, two pairs of through holes are drilled on the connecting valve base (3), and the positions of the through holes are corresponding to the positions of the annular grooves of the three-way valve. The two release prevention U-shaped clamps are inserted inside the two pairs of the through holes to clamp the three-way valve. The hydraulic prop used as a coalface support can effectively prevent the three-way valve flying out from the valve base to cause injury of operators; and can prevent the movable prop from breaking off and prevent deformation of the oil cylinder when knocking the bottom of the prop. The hydraulic prop has light weight and good corrosion-resisting property; and the arrangement of the handle body is reasonable, resulting in flexible and convenient liquid injection and liquid discharging operations.

The specific embodiment
Below in conjunction with drawings and Examples the utility model is further specified.
In the anti-structure that flies the valve hydraulic prop of the utility model shown in Fig. 1～3.It mainly by stud overcap 1, the cylinder 2 of living, connect valve seat 3, combined seal ring 4, handgrip body 5, oil cylinder 6, piston 7, back-moving spring 8, pillar protective jacket 9, base 10, circular baffle plate 11, anticreep U-shaped card 12, triple-use valve 13, spacing steel wire 15, wireway 16, and connect composition such as steel wire 14.It has compared following different with existing hydraulic prop commonly used, i.e. improvements:
1. the valve seat 17 of triple-use valve 13 is arranged on and connects on the valve seat 3, is positioned at a side that connects valve seat 3.Be provided with through hole in the connection valve seat 3, the rod chamber of triple-use valve 13 with oil cylinder 6 is communicated with.Correspondingly, the live plunger tube wall of cylinder 2 is provided with the rod chamber and the interior through hole of plunger tube that is communicated with oil cylinder 6
Suitable position between the two ends of triple-use valve 13 is with machined into twice ring-shaped groove; Bore two pairs of small through hole on the valve seat 17 that triple-use valve is installed, the position of two pairs of small through hole is corresponding with triple-use valve twice groove.Each slotting 12, two anticreep U-shapeds of anticreep U-shaped card card 12 is stuck in the triple-use valve twice ring-shaped groove in two pairs of small through hole, prevents that triple-use valve 13 from flying out, and avoids casualty accident to take place.
Fig. 4～6 illustrate the said structure of the triple-use valve 13 of this pillar and valve seat thereof, anticreep U-shaped card 12.
2. installed pillar protective jacket 9 additional on the excircle of the bottom of oil cylinder 6, prevented to be out of shape, to cause post alive can not be reduced to the fault at the end down because of the workman knocks the oil cylinder 6 that produces.Lining one deck elastomeric material between oil cylinder 6 and the protective jacket 9.
3. in order to alleviate pillar weight, in the cylinder 2 of living, add and welded circular baffle plate 11, can reduce the volume in the cylinder 2 alive, promptly enter the liquid volume in the cylinder 2 alive, thereby alleviate pillar weight.
4. the plunger tube, oil cylinder 6 of cylinder 2 of living adopts the cold drawn seamless steel pipe processing of high accuracy, corrosion resistance and good.Oil cylinder is not afraid of corrosion, and is not tight to water quality requirement, and available down-hole nature clear water injects pillar, saves the expense of oil emulsion.
5. live and be provided with in the cylinder 2 to discharging the wireway 16 of gas in the plunger tube.The upper end of wireway 16 is near circular baffle plate 11, and its lower end is an elbow bend, and elbow passes the barrel of plunger tube, is communicated with the rod chamber of oil cylinder 6.
On the barrel of plunger tube, between elbow, wireway 16 lower end, nylon piston 7, the through hole that is communicated with cylinder rod chamber and rodless cavity is set, as the passage of highly pressurised liquid fluid injection, tapping.
During setting prop, triple-use valve is threaded to the fluid injection position, and highly pressurised liquid rises post alive through the liquid-filling valve of triple-use valve, the rodless cavity that the through hole on the plunger tube enters the oil cylinder bottom.During prop drawing, triple-use valve is threaded to the tapping position, and in-oil cylinder liquid is discharged by the bleeder valve that the through hole on the plunger tube enters rod chamber, triple-use valve, makes post withdrawal alive.Utilize the wireway 16 in the plunger tube, can before discharging in-oil cylinder liquid, the air in the plunger tube at first be discharged.
Owing to live cylinder 2 with connects the pressure that sealing ring between the valve seat 3 bears highly pressurised liquid, to sealing part requirement height, so employing can be born combined seal ring 4 high pressure, good seal performance.
6. in the pillar maximum height during less than 1.2m, in order further to alleviate pillar weight, the plunger tube diameter of the cylinder 2 of living can be contracted to 〉=70mm, and the internal diameter of oil cylinder 6 correspondingly is contracted to 〉=74mm, and the wall thickness of the two can be contracted to 〉=7mm.
