Hydraulic support for low coal seam of the present utility model, its better specific embodiment is:
Comprise two split bases, this hydraulic support for low coal seam is provided with above-mentioned formal dress thrust gear;
The rear portion of described two split bases is connected with the rear end of the rear portion pusher rod of described formal dress thrust gear, and the front end of the anterior pusher rod of described formal dress thrust gear is connected with supporting transporter.
The rear end of described rear portion pusher rod is hinged with junction plate, and the inboard of the interior main muscle at the rear portion of described two split bases is respectively equipped with hinged ear, and the both sides at described junction plate rear portion are hinged with the hinged ear at two split base rear portions respectively.
The hinge hole of both sides, described junction plate rear portion is from front to back outward-dipping plagioclase hole.
The leading edge of described junction plate is outward-dipping from front to back inclined-plane, and corresponding position is provided with the inclined-plane that the inclined-plane with described junction plate leading edge matches on described two split bases.
Gap between inclined-plane on the described split base and the inclined-plane of described junction plate leading edge is less than the hole wall in described plagioclase hole and the gap between the hinge in this hole.
Specific embodiment:
As shown in Figure 1 and Figure 2, anterior pusher rod 1 is connected and fixed by bearing pin 5-1 with round steel guide rail 4, and the every side of bearing pin 5-1 can be two also can be many.The inboard, middle part of round steel guide rail 4 is welded with the connection otic placode, and this connects otic placode and is connected with connector 8 by bearing pin 5-2 again, and connector 8 rear ends are cast with the gudgeon perpendicular to ground, and this gudgeon is connected with the tailpiece of the piston rod of advancing jack 3; Insert in the steel pipe slideway 7 of rear portion pusher rod 2 at round steel guide rail 4 rear portions, and can slide front and back in this slideway, and the cylinder body outside weld of advancing jack 3 is connected to fixedly otic placode, and this otic placode is connected with rear portion pusher rod 2, and fixing with pressing plate 6;
Such as Fig. 3, Fig. 4, shown in Figure 5, there is one group of otic placode the rear end of rear portion pusher rod 2, this otic placode is connected by bearing pin 5-3 with the single hole of junction plate 9 front ends, the base 11 that thrust gear connects is two split bases, two bases, 11 bilateral symmetry, also together, respectively be welded with one group of hinged ear 10 in these base 11 interior main muscle inside during use, this hinged ear 10 is connected with junction plate 9 usefulness bearing pin 5-4; The front end of anterior pusher rod 1 is connected with supporting transporter.
During use, advancing jack 3 cavity of resorption feed liquors, piston rod stretches out, piston rod passes through connector 8(referring to Fig. 1,2) the anterior pusher rod 1 of thrust gear is released, namely support is finished " pushing and sliding " action; When trying to stop people from fighting each other, advancing jack 3 epicoele feed liquors, cylinder body is drawn in, cylinder body drives rear portion pusher rod 2(referring to Fig. 1,2), junction plate 9(is referring to Fig. 3,4,5), base 11 draws in, support is finished " trying to stop people from fighting each other " action.Advancing jack 3 adopts Differential Control, guarantees that support " power of trying to stop people from fighting each other " is greater than " pushing and sliding power ".
The junction plate 9(of the utility model thrust gear is referring to Fig. 3) with the hinge hole of base be two outside plagioclase holes 13, when support " is tried to stop people from fighting each other ", junction plate 9 is drawn in, under the effect of the plagioclase hole of junction plate 9, there is the trend that expands outwardly at the rear portion of two split bases 11, thereby the front end of two split bases is received inwards, is conducive to support and " tries to stop people from fighting each other ".Junction plate 9 is inclined-plane 12-1,12-2 stressed (Fig. 3,4,5) with the stress surface of base 11, when " trying to stop people from fighting each other ", the front end that has also guaranteed two split bases 11 has the trend of receiving inwards, simultaneously, because the gap between junction plate 9 and base hinged ear inclined-plane inclined-plane 12-1, the 12-2 is less than the gap of junction plate 9 with base 11 hinging pin shaft 5-4, thereby avoided bearing pin 5-4 stressed, increased the reliability that the support pushing and sliding are tried to stop people from fighting each other.
As shown in Figure 6, hydraulic support comprises above-mentioned thrust gear, applicable hydraulic support for low coal seam, and particularly the lower Bracket in Thin Coal Seam of high workload resistance Bracket in Thin Coal Seam or minimum altitude more can show its superiority.Have wide range of applications, both can be applied to the fully-mechanized mining working of coal-winning machine exploitation, also can be applied to the fully-mechanized mining working of coal plough exploitation.
