With.Hydraulic prop generally uses oil emulsion, and oil emulsion dosage is big, of high cost, and environment easy to pollute.
Utility model content
The purpose of this utility model is to provide a kind of sections to consume mining single prop, solves existing hydraulic prop and adopts
With the high problem of emulsification oil consumption.
In order to solve the above technical problems, the utility model uses following technical scheme：
A kind of section consumes mining single prop, including hollow oil cylinder and movable post, oil cylinder are nested with movable post, movable post inner top and
Bottom is connected by resetting spring in oil cylinder；The junction of the cylinder upper end and movable post is provided with handle body, handle body lower end
Setting oil cylinder mounting hole is simultaneously connect with oil cylinder, and handle body upper end setting movable post mounting hole is simultaneously contacted with movable post, on the handle body
Triple-use valve is also provided with by triple-use valve mounting hole, triple-use valve is communicated by oil cylinder with the gap of movable post with oil cylinder；The work
It is additionally provided with the casing being placed on outside spring in column, there are gap between the upper and lower ends in the upper and lower ends and movable post of casing,
Being horizontally disposed between the upper and lower ends outer wall and movable post inner wall of casing has an annular slab, annular slab, sleeve outer wall, movable post inner wall it
Between form sealing cavity.
Sealing cavity is formed between annular slab, sleeve outer wall, movable post inner wall, oil emulsion riddles in casing, and seals empty
Intracavitary will not be full of oil emulsion, reduce the dosage of oil emulsion, and when oil emulsion support movable post moves upwards, oil emulsion pushes movable post
While inner top, the annular slab outside lower end is also pushed, annular slab is horizontally disposed, therefore pushes and more stablize.
Preferably, the cavity between the sleeve outer wall and movable post inner wall is additionally provided with inclined support column, it is adjacent
Inclined direction between support column is opposite.Support column plays a supportive role between sleeve outer wall and movable post inner wall, adjacent supports column
Between inclined direction on the contrary, improve mechanical property.
Preferably, the movable post inner wall of the hole installing is provided with magnetic gasket, the magnetic gasket is set to
In annular groove, including the sealing frame of fitting annular groove inner wall setting, permanent magnet, buckplate, buckplate setting
In close movable post side in annular groove, and the first cavity is formed between movable post, magnetic liquid is filled in the first cavity, it is concave-convex

4 inner wall of movable post mounting hole is provided with magnetic gasket 5, and the magnetic gasket 5 is set in annular groove, packet
The sealing frame 6 for being bonded the setting of annular groove inner wall, permanent magnet 7, buckplate 8 are included, the buckplate 8 is set to annular groove
18 side of interior close movable post, and the first cavity 9 is formed between movable post 18, fill magnetic liquid, buckplate 8 in the first cavity 9
The second cavity 11 is formed between sealing frame 6, and magnetic liquid is filled in the second cavity 11；It is recessed that the permanent magnet 7 is bonded annular
What slot madial wall slided up and down is set in the second cavity, and there are gaps between buckplate 8, are provided with 10 one end of antifreeze plate
Permanent magnet 7 is connected, the other end is connect with the groove of buckplate 8, and antifreeze plate 10 is slided up and down with permanent magnet 7.
5 top of magnetic gasket is provided with the first y-type seal ring 12, and Open Side Down for the Y types of the first y-type seal ring 12, institute
5 lower section of magnetic gasket stated is provided with the second y-type seal ring 13, and the opening upwards of second y-type seal ring 13 are described
Second y-type seal ring, 13 lower section is additionally provided with third y-type seal ring 14, and Open Side Down for the Y types of the third y-type seal ring 14.
First y-type seal ring 12 and the second y-type seal ring 13 are mainly used for the secondary seal to magnetic gasket 5, due to movable post 18
What is done is to move back and forth, therefore the magnetic liquid in the first cavity 9 is likely to leak from top, lower section, so the first Y types are close
The Y types of seal 12 and the second y-type seal ring 13 are open towards magnetic gasket 5.And third y-type seal ring 14 is mainly used for
Enhance the sealing between movable post 18 and handle body 1, since oil cylinder is in lower section, the Y types opening of setting third y-type seal ring 14
Downwards.
