Abstract
The utility model discloses a pair of frictional shoes for a bottom-uplifting jack of a mining hydraulic support, belonging to the technical field of mining equipment. Each frictional shoe comprises a flange plate, a round pipe and a base plate, wherein the flange plate and the round pipe are welded, and the base plate and the round pipe are welded. The frictional shoes have the beneficial effects of being simple to manufacture and safe and stable, being capable of prolonging the service life effectively and lowering the production cost.
Description
Technical field
The utility model relates to a kind of friction footwear, specifically is that a kind of mine hydraulic bracket is lifted end jack with the friction footwear, belongs to the mining equipment technical field.
Background technology
General mine hydraulic bracket is lifted end jack and is used the friction footwear to be integral piece, and manufacturing cost is high; Need great amount of time and fund to do forging die; Construction period is nervous, and the difficulty of ensuring the quality of products is big, and is difficult to satisfy construction period; Again because friction shoe joint wall is thin, the dark specification of pipe is many; It is many all will to do the forging die expense, and the difficulty that this friction footwear of while forge is big, is unfavorable for that enterprise reduces production costs.
Summary of the invention
To the problem that above-mentioned prior art exists, the utility model provides a kind of mine hydraulic bracket to lift end jack with the friction footwear, makes simply, and safety and firmness can reduce entreprise cost.
To achieve these goals, the technical scheme that the utility model adopts is: a kind of mine hydraulic bracket is lifted end jack with the friction footwear, comprises flange, pipe and base plate, flange and pipe welding, base plate and pipe welding.
Further, flange is provided with bolt hole.
The beneficial effect of the utility model is: make simply, safety and firmness can improve its application life effectively, has reduced cost of production simultaneously.
Description of drawings
Fig. 1 is the generalized section of the utility model;
Fig. 2 is the right view of the utility model.
Among the figure: 1, flange, 2, pipe, 3, base plate, 4, bolt hole.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is described further.
As depicted in figs. 1 and 2, a kind of mine hydraulic bracket is lifted end jack with the friction footwear, comprises flange 1, pipe 2 and base plate 3, flange 1 and pipe 2 welding, base plate 3 and pipe 2 welding; Flange 1 is provided with bolt hole 4.
During use, the footwear that will rub are placed on the ground, and pipe 2 is put in the jack bottom, carry out the work of jack then, and the bottom of jack just can directly not contact with the soil like this, has protected the bottom of jack effectively.
Improvement as the utility model; Bolt hole can be set on flange; After the use; When mentioning jack, fix, friction footwear and jack are together mentioned, avoided the jack footwear that when mentioning, rub also to stay the situation generation in the soil through the bolt hole 4 that is arranged on the flange 1.
