Abstract
The utility model relates to a portable type individual hydraulic prop capable of injecting liquid at a low position. The individual hydraulic prop comprises a base and an oil cylinder fixed on the base, a plunger is arranged in the oil cylinder, a top cover is arranged outside the top end of the plunger, a sealing cover is fixed in the inner cavity of the top end of the plunger, the bottom part of the sealing cover is connected with one end of a return spring, the other end of the return spring is connected with the base, a guiding handgrip is arranged outside the upper end of the oil cylinder, a liquid injecting valve body is arranged outside a position near the the lower end of the oil cylinder, and a liquid injecting hole communicated with the inner cavity of the oil cylinder is formed in the liquid injecting valve body. The individual hydraulic prop facilitates the liquid injecting operation of operating personnel, solves the difficulty caused when the prop is used for injecting the liquid at a high position, increases the comfort degree and the safeness of the operation, improves the work efficiency, and reduces the production cost.
Description
Technical field
The utility model relates to a kind of mining support apparatus, relates in particular to a kind of portable low level fluid injection hydraulic prop that is used for colliery common mechanical blast mining face and fully-mechanized mining working faces end head temporary lining.
Background technology
Hydraulic prop is a kind of be used in colliery common mechanical blast mining face and fully-mechanized mining working faces end head temporary lining.At present, China except that the minority colliery fully-mechanized mining working uses hydraulic support, most of colliery all is a hydraulic prop at the support apparatus that getting working face uses.Hydraulic prop is the new product that develops behind the elemental metals friction prop, and it has advantages such as in light weight, that stroke is big, specified resistance is big, has obtained using widely in the mine excavation industry.Existing hydraulic prop is made up of top cover, column cap, triple-use valve, handgrip body, oil cylinder, live cylinder, back-moving spring, black box and base, in order to adapt to the needs in differing heights coal seam, hydraulic prop has been stipulated the dimension series of differing heights specification.But, however, still also there are some problems: when the user uses high-order hydraulic prop, because of its fluid injection position on the handgrip valve body on pillar top, height overhead is more than 2 meters, after carrying out liquid filling pole-raising and finishing supporting remove column operation the time, cause and be stranded so, operation is extremely inconvenient, influences production efficiency, and is also dangerous.
The utility model content
The technical problems to be solved in the utility model is: problems such as a kind of comfortableness that can overcome high-order pillar fluid injection difficulty, operation and safety be influenced are provided, make portable low level fluid injection hydraulic prop easy and safe to operate.
The technical scheme that its technical problem that solves the utility model adopts is: a kind of portable low level fluid injection hydraulic prop, comprise base and the oil cylinder that is fixed on the base, described oil cylinder inside is provided with post alive, the outer setting of capital end alive has top cover, the inner chamber of capital end alive is fixed with seal cover, described seal cover bottom is connected with an end of back-moving spring, the other end of back-moving spring is connected with base, described oil cylinder upper end outer setting has the guiding handgrip, outside, the nearly lower end of oil cylinder also is provided with the fluid injection valve body, and described fluid injection valve inner is provided with the liquid injection hole that is communicated with cylinder cavity.
The utility model comprises that further the outside set top cover of described capital end alive is hinged on the outside of capital end alive.
The utility model comprises further that also the fluid injection valve body of the nearly lower end of described oil cylinder outer setting is welded on the oil cylinder outside.
The utility model comprises further that again an end of described back-moving spring is fixed on the link of seal cover bottom centre setting, and the other end of back-moving spring is fixed on another link of base center setting.
The beneficial effects of the utility model are, solved the defective that exists in the background technology, at the position of the outside, nearly lower end of oil cylinder, suitable workman's operation welding fluid injection valve body, embodied the design of hommization, make things convenient for operator's fluid injection work, solved the difficult point of high-order pillar fluid injection, increased the comfortableness and the safety of operation simultaneously, improve operating efficiency, reduced cost of production.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is the structural representation of preferred embodiment of the present utility model;
Wherein: 1, top cover; 2, the post of living; 3, seal cover; 4, back-moving spring; 5, guiding handgrip; 6, fluid injection valve body; 7, oil cylinder; 8, base.
The specific embodiment
With preferred embodiment the utility model is described in further detail in conjunction with the accompanying drawings now.These accompanying drawings are the schematic diagram of simplification, basic structure of the present utility model only is described in a schematic way, so it only show the formation relevant with the utility model.
As shown in Figure 1, a kind of portable low level fluid injection hydraulic prop, comprise base 8 and the oil cylinder 7 that is fixed on the base 8, described oil cylinder 7 inside are provided with post 2 alive, the outside on post alive 2 tops is hinged with top cover 1, the inner chamber on post alive 2 tops is fixed with seal cover 3, the link that described seal cover 3 bottom centre are provided with is connected with an end of back-moving spring 4, the other end of back-moving spring 4 is connected with another link that base 8 centers are provided with, described oil cylinder 7 upper end outer setting have guiding handgrip 5, oil cylinder 7 nearly outsides, lower end also are welded with fluid injection valve body 6, and described fluid injection valve body 6 inside are provided with the liquid injection hole that is communicated with oil cylinder 7 inner chambers.
An embodiment of the present utility model as shown in Figure 1, fluid injection valve body 6 is band handgrip fluid injection valve body.
The course of work of the present utility model is: during setting prop, highly pressurised liquid injects in the triple-use valve of fluid injection valve body 6 by fluid injection gun, enter into the pillar internal cavity by the liquid injection hole that is communicated with oil cylinder 7 inner chambers in the fluid injection valve body 6 again, the post 2 of living drives seal covers 3 and the hinged top lid 1 beginning setting prop that moves upward, with roof supporting; When falling post, the feather valve of the triple-use valve by fluid injection valve body 6 unloads liquid to pillar, and under the effect of deadweight and back-moving spring 4, the post 2 of living drives hinged top lids 1 and seal cover 3 begins to descend, and liquid is by the unloading hole discharge of triple-use valve.Pillar setting prop and fall post is once just finished a working cycles.
According to another embodiment of the present utility model, the fluid injection valve body also can be designed as the common fluid injection valve body of not being with handgrip, and in the bottom with the fluid injection valve body of handgrip not an auxiliary handle is installed, and still can reach same result of use.
With above-mentioned foundation desirable embodiment of the present utility model is enlightenment, and by above-mentioned description, the related work personnel can carry out various change and modification fully in the scope that does not depart from this utility model technological thought.
