Abstract
The utility model relates to a hydraulic column, in particular to a piston-type total-stroke mining single hydraulic supporting column. The supporting column comprises an ejecting cover, a handle body, an mobile column tube, an oil cylinder, a filling oil cylinder, a piston, a reset spring, and a base; the upper part and the lower part of the oil cylinder are respectively provided with the handle body and the base; the inside part of the oil cylinder is sleeved with the mobile column tube; the reset spring is arranged between the mobile column tube and the base; the middle part of the oil cylinder is sleeved with a filling handle body; an auxiliary oil cylinder is sleeved outside the oil cylinder between the filling handle body and the base; the handle body installed on the auxiliary oil cylinder of the hydraulic supporting column changes the way of traditional welding filling valve seat, so as to greatly increase the anti-bending strength of the supporting column; the position of the filling handle body can be changed according to the user requirement; the filling handle body is installed on the auxiliary oil cylinder so as to greatly increase the working stroke of the supporting column and lead the working stroke of the supporting column to be identical to that of the suspension supporting column; the force-bearing state of the original supporting column is changed, and the total load of the supporting column is increased.
Description
Technical field:
The utility model relates to hydraulic prop, especially a kind of piston type total travel mine individual hydraulic prop.
Background technology:
Continuous progress along with the machinery coal mining, mining height also increases thereupon, according to the mine individual hydraulic prop of the big stroke of market survey a lot of colliery needs, the existing big stroke pillar that adopts is based on floated pillar, but floated individual prop in use exposes some shortcomings:
1, lives that anticorrosion, the anti-big gun on post surface jumps, anti-ly collides with, the anti-scratch poor ability.The researcher has taked various technology also can't solve at present.
2, high pressure sealing face is located on the post alive, makes the gap of post alive and handgrip body very little, and it is very difficult that flexibility surpasses gap width (maximal clearance 0.427mm) prop drawing behind the pillar pressurized.
3, high pressure sealing face is located at post alive surface, and the preservative treatment of the post of living is played most important effect to the use of pillar, in case the post surface of living is corroded, the pillar sealing performance descends greatly, even loses efficacy, and influences the use of pillar.Because the colliery subsurface environment is abominable, very high to the aseptic technic requirement, thus each manufacturer does not all find fine solution now.
Summary of the invention:
The technical problems to be solved in the utility model is: provide that a kind of rational in infrastructure, processing technology is simple, anticorrosion, flexural strength is big, and impulse stroke is big, and piston type total travel mine individual hydraulic prop easy to maintenance.
The technical scheme that solves its technical problem employing is:
A kind of piston type total travel mine individual hydraulic prop, comprise: top cover, handgrip body, plunger tube, oil cylinder, fluid injection oil cylinder, piston, back-moving spring, base, its upper and lower part of described oil cylinder is equipped with handgrip body and base respectively, be set with plunger tube in the described oil cylinder, its upper and lower part of this plunger tube is equipped with top cover and piston respectively, be provided with back-moving spring between this plunger tube and the base, described oil cylinder middle part is set with fluid injection handgrip body, and the oil cylinder between this fluid injection handgrip body and the base is set with auxiliary cylinder outward.
Compared with prior art, the beneficial effects of the utility model are:
The auxiliary cylinder of this hydraulic prop is installed the mode that fluid injection handgrip structural reform has become traditional welding fluid injection valve seat, increases the flexural strength of pillar greatly; Fluid injection handgrip body can change the position according to user's needs; Fluid injection handgrip body is installed on the auxiliary cylinder, has increased the impulse stroke of pillar greatly, makes the impulse stroke of pillar identical with the impulse stroke of suspension pillar; Changed the force-bearing situation of former pillar, the hydraulic coupling in the post of promptly living acts directly on the summit, has strengthened the total load of pillar; Working resistance is because of having made full use of hydraulic coupling and unjointed reason than the big 50～70KN of conventional column.
Description of drawings:
Fig. 1 is a structural representation of the present utility model.
Among the figure: top cover 1, plunger tube 2, handgrip body 3, stainless steel sleeve 4, oil cylinder 5, back-moving spring 6, fluid injection handgrip body 7, auxiliary cylinder 8, piston 9, base 10.
The specific embodiment:
The utility model is described in further detail below in conjunction with drawings and Examples:
Shown in accompanying drawing 1, a kind of piston type total travel mine individual hydraulic prop, by top cover 1, plunger tube 2, handgrip body 3, stainless steel sleeve 4, oil cylinder 5, back-moving spring 6, fluid injection handgrip body 7, auxiliary cylinder 8, piston 9, the described oil cylinder of base 10 5 is on it, the bottom is separately installed with handgrip body 3 and base 10, be set with plunger tube 2 in the described oil cylinder 5, this plunger tube 2 is on it, the bottom is separately installed with top cover 1 and piston 9, is provided with back-moving spring 6 between this plunger tube 2 and the base 10, described oil cylinder 5 middle parts are set with fluid injection handgrip body 7, the oil cylinder 5 outer auxiliary cylinders 8 that are set with between this fluid injection handgrip body 7 and the base 10.
As a kind of optimal way of the present utility model, 5 inner surfaces of oil cylinder described in the present embodiment are inlayed stainless steel sleeve 4, and antiseptic power improves greatly, can directly use mine water, can reach the environmental protection purpose.
Gas making process of the present utility model is summarized as follows:
Emulsion in the pumping plant enters in the oil cylinder 5 through auxiliary cylinder 8 through the triple-use valve of installing in the triple-use valve hole on the fluid injection handgrip body 7, and plunger tube 2 is risen, thereby has strengthened the impulse stroke of hydraulic prop.Because this hydraulic prop has changed the position of fluid injection handgrip body 7, reduced the minimum constructive height of hydraulic prop, thereby a kind of pillar can replace multiple mining height.
