Abstract
The utility model discloses an individual hydraulic prop which comprises a base component on which an oil cylinder is arranged; the oil cylinder is internally provided with a movable prop body, the upper end of which is provided with a top cap; the upper end of the oil cylinder is provided with a handle body; and the movable prop body is internally provided with a returning spring, the upper end of which is fixedly connected with the top cap, and the lower end of the returning spring is fixedly connected with the base. The individual hydraulic prop is characterized in that the handle body is provided with a three-use valve, the outlet of which is communicated with the oil cylinder body by a pipeline body; and a reinforcement block and a fixed block which play the protection role are arranged between the pipeline body and the oil cylinder body. Compared with the prior art, the individual hydraulic prop has the advantages of safe operation, reliable work, long stroke and the like.
Description
One, technical field
The utility model relates to the support apparatus that a kind of colliery is used---hydraulic prop.
Two, background technology
Pillar is used with support apparatus widely as the colliery, existing fluid injection mode generally is the bottom that triple-use valve is installed in cylinder alive top or oil cylinder by column cap, but shortcoming is arranged all: triple-use valve is welded on cylinder alive top by column cap, the weld rigidity of cylinder on the one hand alive reduces, the lifting of triple-use valve and column cap with the lifting of pillar, bring difficulty and danger to operation, especially particularly evident for the pillar problem of higher model, increased the accident rate of pillar.Triple-use valve is welded on the oil cylinder by column cap, makes the weld rigidity of oil cylinder reduce, simultaneously because of the installation site of considering this kind of route problem connected mode to try one's best by time, the column operation inconvenience falls in setting prop.
Three, summary of the invention
At above present situation, the utility model proposes provides a kind of triple-use valve to be located on the handgrip body, by the hydraulic prop that the oil pipe body connects, has advantages such as handling safety, reliable operation, stroke length.
For achieving the above object, the technical solution adopted in the utility model is:
A kind of hydraulic prop comprises base assembly, and base assembly is provided with oil cylinder, is provided with cylinder alive in the oil cylinder, the upper end of cylinder alive is provided with top cover, and the upper end of oil cylinder is provided with the handgrip body, is provided with back-moving spring in the cylinder of living, the fixedly connected top cover in back-moving spring upper end, the fixedly connected base in lower end
Described handgrip body is provided with triple-use valve, and the outlet of triple-use valve is communicated with cylinder body through the oil pipe body; Its concrete type of attachment is that base assembly is provided with through hole, and an end of through hole is communicated with triple-use valve through the oil pipe body, and the other end is communicated with cylinder body.
Above-mentioned hydraulic prop, described base are outer-enwraped type, and promptly oil cylinder is set in the base; Be provided with oil pipe body protective device between described oil pipe body and the oil cylinder, described protective device is boss and fixed block, and boss and fixed block are between oil pipe body and oil cylinder.
The beneficial effects of the utility model show:
1, compares with common monomer, remove column cap, triple-use valve has been installed on the handgrip body, both increased the rigidity and the stroke of pillar, have to have solved operating difficulties and danger that the triple-use valve body is brought with the pillar lifting, especially the pillar effect for higher model is more obvious.
2, base adopts outer-enwraped type, when increasing stroke, has also increased the base lifting surface area, and effectively protects the oil cylinder bottom, strengthens oil cylinder rigidity.
3, the oil pipe body adopts the structure of welding boss and fixed block, prevents that tubing section from being injured by a crashing object and produces bending, distortion such as reverse, and effectively protects the oil pipe body, has prolonged the application life of hydraulic prop.
Four, description of drawings
Fig. 1 is a structural representation of the present utility model.
Five, the specific embodiment
The following correlation technique content of not addressing all can adopt or use for reference prior art.
As shown in Figure 1, a kind of hydraulic prop, comprise base assembly 13, described base assembly 13 adopts outer-enwraped type, is arranged with oil cylinder 14 by O-ring seals 11, anti-extrusion ring 12 on the base assembly 13, is arranged with cylinder 15 alive in the oil cylinder 14, the inside, upper end of cylinder 15 alive is provided with dome 18, be provided with O-ring seals 2 and anti-extrusion ring 3 between the two, the cylinder 15 of living, dome 18 upper ends are provided with hinged top lid 1, and hinged top lid 1 is connected steel wire 4 with the cylinder 15 of living by top cover and connects.
The outer cover of the upper end of oil cylinder 14, the cylinder 15 of living is provided with handgrip body 17, and handgrip body 17 connects by being connected steel wire 16 with oil cylinder 14.The handgrip body 17 and 15 of the cylinders of living are provided with dust ring 5 and handgrip body guide ring 6.Living is provided with back-moving spring 21 in cylinder 15 inner chambers, the upper end of back-moving spring 21 by spring carrier arm 19 be connected with dome 18, the lower end is fixedly connected on the base assembly 13.
Described handgrip body 17 is provided with triple-use valve 22, and the outlet of triple-use valve 22 is through the through hole of oil pipe body 8 connection base assemblies 13, and the through hole of base assembly 13 is communicated with cylinder chamber.Described oil pipe body 8 is connected with triple-use valve 22 with locknut 20 by base 7; 14 of oil pipe body 8 and oil cylinders are provided with fixed block 9 and boss 10, and wherein fixed block 9 is provided with two, and upper-lower position respectively is provided with one, and boss 10 is provided with one, between two fixed blocks 9.
During use, triple-use valve 22 is communicated with high-pressure oil pipe, during setting prop, high-pressure oil pipe is by triple-use valve 22, oil pipe body 8, base assembly through hole fuel feeding in the cylinder 15 of living, and the upwards setting prop of cylinder 15 of living is when falling post, the unloading high-pressure oil pipe, under the pulling of back-moving spring 21, the cylinder 15 of living is to the decline post.
This shows that the utility model is installed in triple-use valve on the handle body, and the feed flow in the pillar of the oil pipe body by protective device is arranged, have the advantages such as handling safety, reliable operation, stroke are long.
