Abstract
The utility model relates to a rapidly-lifting suspended single hydraulic prop, which is suitable for supporting underground laneways and a working surface of a mine. The single hydraulic prop comprises a top cover, a moveable prop, a valve seat, a three-way valve, a prop pulling handle, a cylinder body and a base, an inner cavity in the lower part of the moveable prop is provided with a sealing baffle, and the prop pulling handle is arranged the outer wall of the cylinder body on the lower side of the valve seat; and the junction surface of the top cover for buckling with the movable prop is provided with a plurality of connecting pins. As a major part of the inner cavity of the moveable prop is not contacted with working media, anticorrosion treatment is not required for the surface of the inner cavity ; on one hand, the cost of the treatment of the surface of the inner wall of the movable prop is reduced; on the other hand the consumption of the working media is reduced, thereby not only improving the speed of lifting and unloading of the moveable prop but also saving water, the environment pollution caused by the ground working media and the overall cost of the hydraulic prop. The hydraulic prop has the advantages of simple structure, safety, reliability, easy manufacture, convenient operation and use, long service life, and wide practicability.
Description
Technical field
The utility model relates to the floated hydraulic prop of a kind of fast lifting, is particularly useful for the supporting of mine underworkings and work plane.
Background technology
Mining floated hydraulic prop, with advantages such as its lifting force are big, safe, reliable, be widely used under the coal mine main support apparatus as tunnel and work plane, the hydraulic prop that uses mainly is made of oil cylinder, the post of living, triple-use valve at present, and the post upper end of living is equipped with seal cover, the column sealing of living covers the bottom and is connected with base by spring, pillar is in when work, and working media enters the whole inner chamber of post alive by triple-use valve and the gap between post and the cylinder body of living, and with this post alive is risen.Post space in uphill process constantly increases owing to live, and required working media consumption is very big, so lifting speed is slow; During unloading, by the effect of extension spring, working media is discharged, discharge rate is slower.Simultaneously,, can corrode, also must carry out anti-corrosion treatment, thereby increase the manufacturing cost of post alive the post inner surface of living to the post inner chamber of living because a large amount of working medias is stored in post inner chamber alive for a long time.
In addition, the handgrip body is connected with the triple-use valve seat in the existing hydraulic prop, is commonly called as handgrip body triple-use valve, its active force acts on the valve seat when using the handgrip body, can cause the displacement of triple-use valve, can cause the triple-use valve distortion when serious, make its seal failure influence supporting safety.
The utility model content
The purpose of this utility model is the weak point that overcomes in the prior art, provides a kind of simple in structure, and cost is low, and avoiding living, the post inner chamber corrodes and the floated hydraulic prop of fast lifting of triple-use valve displacement.
For achieving the above object, the floated hydraulic prop of fast lifting of the present utility model comprises top cover, post alive, valve seat, triple-use valve, prop drawing handgrip, cylinder body and base, is provided with the sealing closure plate in described post lower lumen alive; Described prop drawing handgrip is located on the outer wall of cylinder body of valve seat downside; Described top cover is provided with a plurality of connecting pins with the bonding surface that the post of living is interlocked.
The described sealing closure plate that is located in the post lower lumen alive is the arc shape that the middle part raises up, and the post of living is a hollow tube; The periphery of described sealing closure plate welds together with the column wall pipe face of living.
The floated hydraulic prop of fast lifting of the present utility model, existing hydraulic prop is transformed, in the post lower lumen of living, be provided with the sealing closure plate, seal cover and spring in the former pillar have been removed, the cylinder handgrip is separated with valve seat, be installed on the cylinder body, when using handgrip, do not influence triple-use valve, make pillar safer, more reliable.The big portion of post inner chamber does not contact with working media owing to live, and the surface does not need to carry out unnecessary preservative treatment, greatly reduces column wall process of surface treatment cost alive, has prolonged application life, has saved the cost of post loam cake alive and extension spring simultaneously yet.Because the working media consumption significantly reduces, and has not only improved the speed of post lifting alive and unloading, and has saved water, reduced the environment pollution that the ground handling medium causes, reduced the whole cost of hydraulic prop, it is simple in structure, easy to manufacture, easy for operation, have practicality widely.
Description of drawings
Accompanying drawing is the floated hydraulic prop structure chart of fast lifting of the present utility model.
Among the figure: the 1-top cover, 2-post alive, the 3-valve seat, the 4-triple-use valve, 5-prop drawing handgrip, the 6-cylinder body, 7-seals closure plate, 8-base.
The specific embodiment
The utility model will be further described below in conjunction with the embodiment in the accompanying drawing:
Shown in the accompanying drawing: the floated hydraulic prop of fast lifting is made of top cover 1, the post 2 of living, valve seat 3, triple-use valve 4, tubular prop drawing handgrip 5, cylinder body 6, sealing closure plate 7 and base 8 with handles.Wherein top cover 1 is fastened on the post 2 alive, and its bonding surface is fixedly connected by a plurality of connecting pins, and the post 2 of living is sleeved in the cylinder body 6, and cylinder body 6 is fixed in the base 8.Valve seat 3 is fixed on the outlet barrel of cylinder body 6, simultaneously and live and be tightly connected between post 2 barrels, is provided with guide ring between valve seat 3 and the work post 2, and triple-use valve 4 is located on the valve seat 3, and prop drawing handgrip 5 is fixed on the outer wall of cylinder body 6 of valve seat 3 downsides.Sealing closure plate 7 is fixed in the inner tubal wall of post alive 2 bottoms, the arc shape that sealing closure plate 7 raises up for the middle part, and the post 2 of living is a hollow tube, the periphery of sealing closure plate 7 welds together with the post 2 inner wall tube faces of living.
Operating principle: high-pressure medium enters post alive 2 bottoms through triple-use valve 4 by the gap of living between post 2 and the cylinder body 6, and medium only need be full of the inner chamber by 7 sealings of sealing closure plate, and post 2 alive is risen, and the movement top cover rises, and reaches the effect of supporting.Because the working media consumption significantly reduces, and during unloading, need not the pulling force of spring, lean on the gravity of cylinder self to get final product release, and the speed of unloading is fast, safe and reliable, operating efficiency improves greatly.
