Abstract

The utility model discloses a mining single hydraulic prop, and relates to a mining device as a support in a mine. The mining single hydraulic prop comprises: a top cover, a moveable column, a moveable column upper cover, a cylinder body, a cylinder body upper cover, a return spring, a handgrip body three-purpose valve, and a base. The moveable column can not be used due to pocking marks formed at the surface of the moveable column, in order to save cost, a repairing layer made from resin materials is sprayed at the surface of the moveable column, and a wear-resistant layer made from polyurethane materials is sticked to the sealing surface of a sealing ring, and the quality of the repaired moveable column is the same as the quality of a new moveable column. The mining single hydraulic prop is advantageous in that, the moveable repairing layer is made from resin materials, the sealing ring wear-resistant layer is made from polyurethane materials, and the hardness and wear resistance of the above two are close, sealing effect is good, service lifetime is long, and quality of the single hydraulic prop is guaranteed; the mining single hydraulic prop is also advantaged by simple repairing technology, high efficiency, and easy popularization and use.

Description

Mine individual hydraulic prop
Technical field
The utility model relates to a kind of mining equiment, is specifically related to be used under a kind of mine the floated hydraulic prop of supporting.
Background technology
Floated mine individual hydraulic prop, big with its lifting force, advantage such as safe and reliable is widely used in colliery underworkings and the work plane equipment as supporting.Because the work condition environment condition is too poor under the coal mine, especially when blowing out, the stone wound is hit the post of living, and forms pit on the post surface of living, the influence sealing, and the pillar lifting force descends, and pillar can't use when serious, have to scrap, must be from the pillar that newly more renews.But other positions of pillar still are intact, if will live post surface repairing and reusing, will reduce cost significantly.
Summary of the invention
In order to solve above technical problem, the utility model provides a kind of mine individual hydraulic prop.To can't use owing to the surface forms pit, post surface spraying one deck resin material repair layer of living is pasted the sealing surface of sealing ring the wear-resisting layer of one deck polyurethane simultaneously, and the post alive after the reparation is the same with the new post quality of living.
The utility model is achieved by the following technical solution: a kind of mine individual hydraulic prop comprises: top cover, the post of living, live post loam cake, cylinder body, cylinder cover, return spring, handgrip body triple-use valve and base; The described top cover and the post loam cake of living are installed in the upper end of post alive by hollow pins, and described cylinder cover is installed in the upper end of cylinder body, and cylinder cover is connected with the external cylindrical surface of work post by sealing ring, dust ring; Described base is installed in the lower end of cylinder body, and described handgrip body triple-use valve is installed on the cylinder cover.Live and to be connected by return spring between post loam cake and the base; It is characterized in that: post repair layer alive is arranged on the external cylindrical surface of described post alive; On the contact surface of the described sealing ring and the post of living wearing layer is arranged.
Described post repair layer alive adopts resin material to make.
Described wearing layer adopts polyurethane material to make.
Described post repair layer alive adopts the method for spraying to be coated onto on the face of cylinder of post alive.
Described wearing layer adopts the method for pasting to paste the sealing ring surface.
Good effect of the present utility model is:
1, the post finish alive after the reparation is the same, safe and reliable with the new post of living.
When 2, living the reparation of post and sealing ring, adopt resin and polyurethane material, both hardness and abrasion resistance are close, and application life is close with new pillar.
3, rehabilitation cost improves business efficiency greatly far below the cost of new pillar.
4, renovation technique is simple, and the efficient height is convenient to promote the use of.
Description of drawings
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
Accompanying drawing is the utility model structural representation.
Among the figure: 1, top cover, 2, the post loam cake of living, 3, the post of living, 4, the post repair layer of living, 5, cylinder cover, 6, handgrip body triple-use valve, 7, sealing ring, 8, wearing layer, 9, cylinder body, 10, return spring, 11, base.
The specific embodiment
As shown in drawings: a kind of mine individual hydraulic prop comprises: top cover 1, the post 3 of living, live post loam cake 2, cylinder body 9, cylinder cover 5, return spring 10, handgrip body triple-use valve 6 and base 11.The described top cover 1 and the post loam cake 2 of living are installed in the upper end of post 3 alive by hollow pins, and described cylinder cover 5 is installed in the upper end of cylinder body 9, and cylinder cover 5 is connected with the external cylindrical surface of work post 3 by sealing ring 7, dust ring.Described base 11 is installed in the lower end of cylinder body 9, and described handgrip body triple-use valve 6 is installed on the cylinder cover 5.Live and to be connected by return spring 10 between post loam cake 2 and the base 11; It is characterized in that: post repair layer 4 alive is arranged on the external cylindrical surface of described post 3 alive; On the contact surface of the described sealing ring 7 and the post 3 of living wearing layer 8 is arranged.
Described post repair layer alive 4 adopts resin material to make.
Described wearing layer 8 adopts polyurethane material to make.
Live post repair layer 4 and wearing layer 8 adopts close material, and both hardness and abrasion resistance are close, good sealing effect, and long service life is guaranteed the quality of hydraulic prop.
Described post repair layer alive 4 adopts the method for spraying to be coated onto on the face of cylinder of post 3 alive.
Described wearing layer 8 adopts the method for pasting to paste sealing ring 7 surfaces.
The process that adopts spraying and paste, renovation technique is simple, and the efficient height is convenient to promote the use of.
