Abstract
The utility model relates to a kind of light-duty mining single hydraulic supporting column with suspension type plunger, it comprises oil cylinder, be located at in-oil cylinder post alive be located at the top cover on post top alive and seal cover assembly be connected the suitable for reading of oil cylinder and the handle body between post of living, be connected oil cylinder bottom ports liquid-filling valve, be connected with liquid-filling valve add long column and fixed oil cylinder, liquid-filling valve and add the adapter sleeve of long column, be also provided with the back-moving spring be connected between described seal cover assembly and liquid-filling valve in described post alive; The beneficial effects of the utility model are: 1, because liquid-filling valve of the present utility model is arranged on oil cylinder bottom ports, after pillar discharge opeing, pillar inner chamber can not accumulate liquid; 2, add long column because valve body one end of the present utility model connects, and long column inner chamber is designed to hollow body, no liquid; Therefore pillar of the present utility model in use overall weight significantly alleviate, realize hydraulic prop lightness, workman is convenient to install, carrying, reduce labour intensity, strengthen labor safety.
Description
Technical field
The utility model relates to a kind of light-duty mining single hydraulic supporting column with suspension type plunger, belongs to mining equiment technical field.
Background technology
Mining single hydraulic supporting column with suspension type plunger conventional at present, liquid mode is unloaded in its fluid injection roughly two kinds: 1, handle valve body fluid injection is installed on oil cylinder top and unloads liquid, 2, in the middle part of oil cylinder, weld liquid-filling valve fluid injection unload liquid, these two kinds of post liquid unload liquid mode and all there is a problem, because the liquid of valve body enters, go out top or middle part that port is arranged on oil cylinder, therefore the large quantity of fluid accumulated in pillar inner chamber cannot be emptying, pillar overall weight is caused significantly to increase, the hydraulic prop produced is made to seem heavy in use, install, carrying inconvenience, consume workman physical in a large number.Thus coal miner be badly in need of a kind of lightweight, be convenient to the light-duty mining single hydraulic supporting column with suspension type plunger installed and used.
Summary of the invention
In order to overcome above-mentioned the deficiencies in the prior art part, the utility model provides a light-duty mining single hydraulic supporting column with suspension type plunger, its structure design effectively alleviates mining single hydraulic supporting column with suspension type plunger weight in use, alleviates the labour intensity of coal miner in carrying.
The utility model is achieved by the following technical solution: a kind of light-duty mining single hydraulic supporting column with suspension type plunger, it comprises oil cylinder, be located at in-oil cylinder post alive be located at the top cover on post top alive and seal cover assembly be connected the suitable for reading of oil cylinder and the handle body between post of living, be connected oil cylinder bottom ports liquid-filling valve, be connected with liquid-filling valve add long column and fixed oil cylinder, liquid-filling valve and add the adapter sleeve of long column, be also provided with the back-moving spring be connected between described seal cover assembly and liquid-filling valve in described post alive.
Described liquid-filling valve is provided with the face of cylinder be connected with oil cylinder and adapter sleeve inwall, the described face of cylinder is provided with seal groove, the described face of cylinder is provided with a cavity be connected with triple-use valve, and cavity is provided with another cavity, and its two cavity is mutually vertically through; Described liquid-filling valve is also provided with the suspension hook connecting back-moving spring.
Described adapter sleeve is provided with the inwall be connected with fixed oil cylinder, liquid-filling valve and extension bar outer wall, which is provided with and coordinates with liquid-filling valve cavity the circular hole communicated.
Described extension bar is a sleeve, and one end connects liquid-filling valve, and the other end connects end cap.
The beneficial effects of the utility model are: 1, because liquid-filling valve of the present utility model is arranged on oil cylinder bottom ports, after pillar discharge opeing, pillar inner chamber can not accumulate liquid; 2, add long column because valve body one end of the present utility model connects, and long column inner chamber is designed to hollow body, no liquid; Therefore pillar of the present utility model in use overall weight significantly alleviate, realize hydraulic prop lightness, workman is convenient to install, carrying, reduce labour intensity, strengthen labor safety.
Accompanying drawing explanation
According to drawings and embodiments the utility model is further illustrated below.
Fig. 1 is the utility model structural representation.
Detailed description of the invention
