Abstract
The invention discloses a thruster. The thruster comprises an oil cylinder support, a hydraulic oil cylinder which is installed on the oil cylinder support and a thruster box which is connected with the hydraulic oil cylinder through an oil pipe. The thruster further comprises a fixing reinforcing board and at least two screw rods. Two ends of the screw rods respectively penetrate through the fixing reinforcing board and the oil cylinder support and are positioned through a first bolt and a second bolt. The thruster can enable an oil cylinder piston to push the pushing pin to move forward through pressing a pressure rod of the thruster box and arranging the pushing pin, so that when the range is exceeded, the operational need of the hydraulic oil cylinder can be met through the adjustment of a screw rod without replacing a long or a short pushing pin repeatedly. The operational need of the hydraulic oil cylinder can be met through the adjustment of a screw rod without a creeper tread. Working efficiency is improved more than two thirds. The thruster is low in cost and reduces labor intensity of workers. The thruster is a special tool which is worthwhile to popularize.

Technical field
The present invention relates to track chain dismounting maintenance of equipment technical field, particularly a kind of horse device that draws.
Background technology
At present, what track chain needed the general employing of dismounting maintenance is to open the old way that the bull-dozer chain keeps in repair, and namely bakes by fire to add sledgehammer, and manual labor is heavy, and operating efficiency is not high.In order to reduce labour intensity and to increase work efficiency, a kind of horse device that draws has appearred at present, and it is dismounting track link in the middle of a kind of tracked construction equipment regular maintenance, indispensable instrument when extruding bearing pin by being pressed into.
As shown in Figure 1, traditional horse device that draws generally comprises hook 12, hydraulic jack fixed mount 11, hydraulic jack 14 and La Ma device box 17.Wherein, three hook-shaped hook 12 1 end strap bolts 13, three hooks 12 are hooked respectively on the diverse location of creeper tread, load onto respectively hydraulic jack fixed mount 11 and hydraulic jack 14, be connected with hydraulic jack 14 with drawing horse device box 17 respectively by hydraulic oil pipe 15, press the press rods of drawing horse device box 17, supply with hydraulic jack 14 will draw the hydraulic oil in horse device box 17, the piston rod that drives hydraulic jack 14 stretches out.Load onto pushing pin 16, regulate three hook 12 be stressed reach balance after, then press press rods, when piston rod moves forward over the stroke of hydraulic jack 14, just hydraulic jack 14 is return, change next pushing pin 16, need repeatedly just can complete back and forth an ejector pin operation.
Tradition draws the horse device to have following defective:
1) stressed evenly being not easy of hook-shaped connection grasped, and must repeatedly dismantle each gib head of adjustment and make its stress equalization, but be difficult to reach perfect condition, and mechanical strength is inadequate, single hook phenomenon of rupture often occurs thus;
2) due to complex operation, and repeatedly change pushing pin, cause the operating time long, affect maintenance efficiency;
3) limitation, if there is no creeper tread as support, hook-shaped connection does not have due effect, wants to take out when only having chain or is pressed into bearing pin and do not accomplish, original horse device complex operation that draws often has fault.
Therefore, how to avoid the appearance of single hook phenomenon of rupture, and also can take out or be pressed into bearing pin when only having chain, become the technical problem that those skilled in the art need to be resolved hurrily.
Summary of the invention
In view of this, the invention provides a kind of horse device that draws, avoiding the appearance of single hook phenomenon of rupture, and also can take out or be pressed into bearing pin when only having chain.
For achieving the above object, the invention provides following technical scheme:
A kind of horse device that draws, comprise the oil cylinder frame, be arranged at the hydraulic jack on described oil cylinder frame, and draw horse device box with described hydraulic jack by what oil pipe was connected, also comprise fixedly stiffener and at least two screw rods, described fixedly stiffener and described oil cylinder frame are passed respectively in the two ends of described screw rod, and respectively by the first bolt and the second Bolt to position.
Preferably, draw the horse device above-mentioned, described screw rod is three, and be on the described fixedly stiffener of being arranged in of isosceles triangle.
