Abstract
The utility model discloses an individual hydraulic prop dustproof cover, which is characterized in that the dustproof cover is a flexible barrel-shaped object, the two ends of the dustproof cover are straight barrels, and the middle part of the dust proof cover is a corrugated pipe. In the utility model, after the individual hydraulic prop dustproof cover is additionally arranged, the affection to an individual hydraulic prop by the dust under a coal mine can be reduced to the lowest degree, thereby completely achieving the aim that the dustproof cover with simple structure can effectively prevent the dust.
Description
Technical field
The utility model relates to a kind of dustproof construction, relates in particular to a kind of hydraulic prop dirt-proof boot.
Background technology
Hydraulic prop is a kind of down-hole support apparatus that is mainly used in the colliery, because dust content is higher under the coal mine, dust very easily enters cylinder tube by the gap of living between post and the cylinder tube, the wearing and tearing between aggravation cylinder tube barrel and piston or the mast alive.Prior art generally all is to adopt dust cap, sets up mode such as dust ring and stops dust to enter oil cylinder, has not only increased the manufacturing cost of hydraulic prop, does not also reach the purpose that intercepts dust effectively.
The utility model content
It is a kind of simple in structure and can effectively stop the hydraulic prop dirt-proof boot of dust that the purpose of this utility model is to provide in order to overcome the deficiencies in the prior art.Its concrete technical scheme is: the hydraulic prop dirt-proof boot is a flexible tubular object, and its two ends are straight tube, and the middle part is a bellows.
When using the utility model hydraulic prop dirt-proof boot; the hydraulic prop dirt-proof boot is placed in outside the cylinder alive; its upper and lower end is individually fixed on top cover and the handgrip by connecting steel wire respectively; the hydraulic prop dirt-proof boot moves with the cylinder of living upper and lower and shrinks or launch, and makes the external surface of cylinder alive and the gap between work cylinder and the oil cylinder be in the seal protection state.From the technical solution of the utility model as can be seen, after having set up the hydraulic prop dirt-proof boot, dust can drop to minimumly under the coal mine to the influence of hydraulic prop, and it is simple in structure to have reached the utility model fully, can effectively stop the goal of the invention of dust.
Description of drawings
Fig. 1 is the structural representation of the utility model hydraulic prop dirt-proof boot.
The specific embodiment
