Abstract
The utility model relates to a kind of mine individual hydraulic prop, comprise hydraulic prop body, in described hydraulic prop body, triple-use valve is installed, the lower end of described hydraulic prop body is provided with base, four grooves are offered in described base, in each groove, be provided with roller, described roller is hinged on the piston rod of hydraulic cylinder.The utility model structure is simple, reasonable in design, by being provided with roller, when needs transport hydraulic prop, Driven by Hydraulic Cylinder roller is only needed to stretch out groove, this roller can be used to be transported by hydraulic prop, when needs use hydraulic prop, by hydraulic cylinder, roller is shunk back in groove.
Description
Technical field
The utility model relates to technical field of mining equipment, particularly relates to a kind of mine individual hydraulic prop.
Background technology
Rich coal resources in China, fully-mechanized mining equipment is ripe, and coal winning technology is gradually improved, in short supply along with the energy, and the quickening day by day of coal in China exploitation paces, thing followed environment suffers serious destruction.
In the operation of colliery, hydraulic prop is the equipment often used, and such as, when carrying out underworkings support, coal-face support, often uses the carrying out of hydraulic prop complexed metal articulated roof beam to support.Hydraulic prop is a kind of support equipment of new environment-friendly type, both can adopt face timbering top board and fully-mechanized mining working supporting termination with metal hinge top beam is supporting for high-grade conventional mining and big gun, also can do separately a post or other temporary supporting use.Hydraulic prop is applicable to the inclined seam stope that seam inclination is less than 25 degree of-35 degree.Scroll wheel is not installed in hydraulic prop of the prior art, is not easy to transport.
Utility model content
In order to overcome the deficiencies in the prior art, the utility model provides a kind of mine individual hydraulic prop, is convenient to transport.
The utility model is achieved through the following technical solutions:
A kind of mine individual hydraulic prop, comprise hydraulic prop body, in described hydraulic prop body, triple-use valve is installed, the lower end of described hydraulic prop body is provided with base, four grooves are offered in described base, in each groove, be provided with roller, described roller is hinged on the piston rod of hydraulic cylinder.
As optimal technical scheme of the present utility model, described hydraulic prop body comprises post alive and sleeve, and described column sleeve alive is located in sleeve, and is formed with an airtight cylinder body between the piston of described post bottom alive and sleeve bottom.
As optimal technical scheme of the present utility model, the lower end of described sleeve is provided with sleeve base, and described sleeve base embeds in base.
As optimal technical scheme of the present utility model, in described sleeve, extension spring being installed, post alive can being made to extend in support process and produce pulling force, when automatically shortening after the fluid pressure unloading in airtight cylinder body, thus making post alive return to home position.
Compared with prior art, the beneficial effects of the utility model are: the utility model structure is simple, reasonable in design, by being provided with roller, when needs transport hydraulic prop, Driven by Hydraulic Cylinder roller is only needed to stretch out groove, this roller can be used to be transported by hydraulic prop, when needs use hydraulic prop, by hydraulic cylinder, roller is shunk back in groove.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In figure: 10-hydraulic prop body; 20-triple-use valve; 30-base; 40-groove; 50-roller; 60-hydraulic cylinder; 70-piston rod; 11-post alive; 12-sleeve; 13-piston; 14-cylinder body; 15-base; 16-extension spring.
Detailed description of the invention
In order to make the purpose of this utility model, technical scheme and advantage clearly understand, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the utility model, and be not used in restriction the utility model.
Refer to Fig. 1, Fig. 1 is structural representation of the present utility model.
Described a kind of mine individual hydraulic prop, comprise hydraulic prop body 10, in described hydraulic prop body, triple-use valve 20 is installed, described hydraulic prop body 10 comprises post 11 alive and sleeve 12, described post alive 11 is set in sleeve 12, and bottom the piston 13 of described post alive 11 bottom and sleeve 12 between be formed with an airtight cylinder body 14, the lower end of described sleeve 12 is provided with sleeve base 15, described sleeve base 15 embeds in base 30, in described sleeve 12, extension spring 16 is installed, post alive can be made to extend in support process and to produce pulling force, when automatically shortening after the fluid pressure unloading in airtight cylinder body, thus make post alive return to home position.The lower end of described hydraulic prop body 10 is provided with base 30, offers four grooves 40 in described base 30, in each groove 40, be provided with roller 50, and described roller 50 is hinged on the piston rod 70 of hydraulic cylinder 60.By being provided with roller 50, when needs transport hydraulic prop, only need hydraulic cylinder 60 driving rolls 50 to stretch out groove 40, this roller can be used to be transported by hydraulic prop, when needs use hydraulic prop, by hydraulic cylinder, roller is shunk back in groove.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all do within spirit of the present utility model and principle any amendment, equivalent to replace and improvement etc., all should be included within protection domain of the present utility model.
