Description
Technical field
The present invention relates to a kind of hydraulic support of coal mine fully-mechanized mining working, relate in particular to a kind of hydraulic support thrust gear and hydraulic support for low coal seam.
Background technology
Current, the employed hydraulic support for low coal seam in colliery, its thrust gear mostly are the form of passing the jack formal dress, promptly adopt floating type piston to pass jack, and piston rod stretches out forward.
Jack strength unreasonable distribution, piston damage easily.
Summary of the invention
The purpose of this invention is to provide a kind of jack strength and distribute hydraulic support thrust gear and hydraulic support for low coal seam reasonable, long service life.
The objective of the invention is to be achieved through the following technical solutions:
Hydraulic support thrust gear of the present invention, comprise and pass jack, anterior pusher rod and rear portion pusher rod, described rear portion pusher rod is connected with the base of hydraulic support, described passing jack adopt cylinder body preceding, piston rod after the upside-down mounting form, and described cylinder body is connected with described rear portion pusher rod, and described piston rod is connected with described anterior pusher rod.
Hydraulic support for low coal seam of the present invention, this hydraulic support for low coal seam are provided with above-mentioned hydraulic support thrust gear.
As seen from the above technical solution provided by the invention, hydraulic support thrust gear provided by the invention and hydraulic support for low coal seam since pass jack adopt cylinder body preceding, piston rod after the upside-down mounting form, promptly cylinder bottom forward, piston rod stretches out backward.The upper and lower chamber of passing jack by upside-down mounting advance back liquid, make anterior pusher rod stretch out or regain, support is finished pushing and sliding and the do action of trying to stop people from fighting each other, when passing jack cavity of resorption feed liquor, because the rear portion pusher rod is connected with base, so support is drawn forward into, promptly " tries to stop people from fighting each other "; When passing jack epicoele feed liquor, anterior pusher rod is released forward, i.e. " pushing and sliding ".Because " trying to stop people from fighting each other " is for passing the cavity of resorption feed liquor of jack, so " power of trying to stop people from fighting each other " of support is greater than " pushing and sliding power ".Jack strength is distributed rationally, has prolonged the application life of piston greatly.

The specific embodiment
Below in conjunction with accompanying drawing the embodiment of the invention is described in further detail.
Hydraulic support thrust gear of the present invention, its preferable specific embodiment is:
Comprise and pass jack, anterior pusher rod and rear portion pusher rod, described rear portion pusher rod is connected with the base of hydraulic support, it is characterized in that, described passing jack adopt cylinder body preceding, piston rod after the upside-down mounting form, and described cylinder body is connected with described rear portion pusher rod, and described piston rod is connected with described anterior pusher rod.
Described anterior pusher rod is connected with the round steel guide rail, and described rear portion pusher rod is connected with the steel pipe slideway, and described round steel guide rail is inserted in the described steel pipe slideway.
Described round steel guide rail has two, and the rear end of two round steel guide rails links together and is connected with the end of described piston rod.
Described steel pipe slideway has two, and described cylinder body and described steel pipe slideway link together.
Hydraulic support for low coal seam of the present invention, this hydraulic support for low coal seam are provided with above-mentioned hydraulic support thrust gear.
The base rear end of described hydraulic support for low coal seam is provided with hinge hole, and the rear end of described rear portion pusher rod and the hinge hole of described base rear end are hinged with bearing pin, and the front end of described anterior pusher rod is connected with supporting scratch board conveyor.
Two parts before and after hydraulic support of the present invention and thrust gear, pusher rod are divided into, anterior pusher rod can be slided in the steel pipe slideway of rear portion pusher rod by the round steel guide rail, and the rear portion pusher rod is connected with bearing pin with base; Pass the form of jack employing " upside-down mounting ", its cylinder body and piston rod are connected with anterior respectively at the rear portion of pusher rod, the upper and lower chamber of passing jack by upside-down mounting advance back liquid, make anterior pusher rod stretch out or regain, support is finished pushing and sliding and the do action of trying to stop people from fighting each other.
Specific embodiment:
As shown in Figure 1 and Figure 2, anterior pusher rod 1 is connected and fixed by connecting pin 5 with round steel guide rail 4, and connecting pin 5 every sides can be 2 also can be many.The inboard of round steel guide rail 4 rear ends is welded with the otic placode 6 that connects usefulness, the otic placode 6 of two round steel guide rails 4 is a symmetric arrangement, connect two otic placodes 6 by front pressuring plate 7, make the rear end of two round steel guide rails 4 connect into an integral body, be connected with connecting pin with the piston rod of passing jack 3 then.
Pusher rod 2 both sides in rear portion are welded with steel pipe slideway 8, can make round steel guide rail 4 portion's slip within it, and the cylinder body both sides of passing jack 3 are welded with fixedly otic placode, and are fixing with rear portion pusher rod 2, push down with rear fender 9.
As shown in Figure 3, Figure 4, base 10 rear ends of hydraulic support are provided with hinge hole, and the rear end of rear portion pusher rod 2 also is provided with hinge hole, can be hinged with bearing pin 11 with the hinge hole behind the base 10.The front end of anterior pusher rod 1 can be connected with supporting scratch board conveyor.
Among the present invention, pass the form that jack 3 adopts " upside-down mounting ", promptly cylinder bottom forward, piston rod stretches out backward.Supposing to pass jack 3 original states is that piston rod is regained, and behind the cavity of resorption feed liquor, because rear portion pusher rod 2 is connected with base 10, so support is drawn forward into, promptly " tries to stop people from fighting each other "; Epicoele feed liquor then, anterior pusher rod 1 is released forward, i.e. " pushing and sliding ".Because " trying to stop people from fighting each other " is for passing the cavity of resorption feed liquor of jack 3, so " power of trying to stop people from fighting each other " of support is greater than " pushing and sliding power ".Anterior pusher rod 1 is slided in the steel pipe slideway 8 of rear portion pusher rod 2, has guaranteed that " pushing and sliding " reach " trying to stop people from fighting each other " process stabilization.
Hydraulic support of the present invention and thrust gear both can be applied to the fully-mechanized mining working that coal-winning machine is exploited, and also can be applied to the fully-mechanized mining working of coal plough exploitation.
The above; only for the preferable specific embodiment of the present invention, but protection scope of the present invention is not limited thereto, and anyly is familiar with those skilled in the art in the technical scope that the present invention discloses; the variation that can expect easily or replacement all should be encompassed within protection scope of the present invention.Therefore, protection scope of the present invention should be as the criterion with the protection domain of claims.
