Abstract
The utility model discloses a supporting prop with elastic protection layer, which is characterized in that a surface-coarsened plunger surface is coated partly or completely by an elastic body in elastic body coating technique, overcoming the disadvantages of poor impact resistance, poor inhibition of corrosion and high cost in the prior art. The service life is prolonged over two times. The utility model is not only suitable for the prop plunger protection of a hydraulic pressure supporting prop, but also for the protection of similar supporting props.
Description
The said support post with elasticity overcoat of the utility model belongs to the invention that piston rod is used as support component.
The resistance to impact of existing support post, abrasion resistance, corrosion resistance are very poor, it is very short to make it application life, the scope of application is also very narrow, and people have adopted methods such as chromium plating, galvanizing phosphorization, spinning stainless steel to solve these problems, but owing to chromium plating often exists because of hole, galvanizing phosphorization is not corrosion-resistant and rust is dead, peel off, spinning stainless steel cost is too high, can not satisfy the widespread demand of general support post.
The purpose of this utility model is exactly in order to address the above problem.
The utility model is to address the above problem to have adopted the overcoat of special elastomer as support post, at first with the surface coarsening of metal stick harness, clad a kind of special bullet gonosome overcoat (rubber, plastics etc.) then thus reached the purpose of protection, improved the resistance to impact of support post widely, corrosion-resistant and corrosion resistance, thus the application life and the range of application of support post improved.Experiment can make be enhanced about more than once the application life of support post through inside, and has widened use face.
An embodiment of the present utility model is made up of bearing (1), plunger (2), elastic body topping (3), handle (4), cylinder body (5) as shown in the figure; being plugged with plunger (2), plunger (2) and cylinder body (5) on bearing (1) is connected; slidably handle (4) is arranged on cylinder body (5); elastic protective layer (3) partly or comprehensively clads the work plane of the external surface of plunger (2), and plunger slides in cylinder body.
The utility model can be widely used in the down-hole coal excavation working face and machine is adopted on the face, also can use under similar working condition; Be not only applicable to be applicable on the security application of other similar support post in the protection of hydraulic prop post plunger.
Claims (1)
1, the said a kind of support post with elasticity overcoat of the utility model is made up of bearing (1), plunger (2), elastic body topping (3), handle (4), cylinder body (5), it is characterized in that the work plane alligatoring rear section of the external surface of metal plunger or all clads flexible body overcoat.
