The specific embodiment
Below in conjunction with accompanying drawing the utility model embodiment is described in further detail.
Hydraulic support thrust gear of the present utility model, 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 utility model, 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 utility model 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.
