The specific embodiment
As shown in Figure 1 and Figure 2, this electric hydraulic disassembling and assembling machine of coupling buffer device for rolling stock is made of the hydraulic dismounting mechanism of driving vehicle frame 10, the 10 anterior assemblings of driving vehicle frame and the hydraulic pressure pressure-bearing mechanism of rear portion assembling, the rear portion of driving vehicle frame 10 is equipped with two universal wheels 1, the front portion is equipped with the directional wheel 8 of two fore-and-aft directions, be equipped with the vehicle frame elevating mechanism at the bottom of the anterior car, the directional wheel 11 of a left and right directions respectively is housed under two lifting swinging mountings about the vehicle frame elevating mechanism, and the two-piston bar of vehicle frame hoist cylinder 9 and lifting swinging mounting are hinged.The hydraulic jack of above-mentioned hydraulic pressure pressure-bearing mechanism adopts double-stage double-acting telescopic ram 2, the piston rod part of oil cylinder 2 is equipped with pressure-bearing bearing 3, above-mentioned hydraulic dismounting mechanism is by the carriage hoist cylinder, the carriage 6 of carriage hoist cylinder piston rod part assembling, the claw hook mechanism of carriage 6 middle parts assembling, two of the symmetry assembling are unloaded hook oil cylinder 7 formations on the carriage of claw hook mechanism both sides, the top of unloading the piston rod of hook oil cylinder 7 is equipped with bearing 5, claw hook mechanism rotates the claw hook 4 that is assemblied in the carriage in opposite directions by two and constitutes, be hinged with the manual pull bar of a cover on two claw hooks 4, manually pull bar and two claw hooks 4 form the connecting rod structure, by the manual pull bar of push-and-pull, can realize the opening and closing of claw hook 4, above-mentioned each oil cylinder links to each other by the hydraulic control circuit oil pump, and the magnetic valve in the hydraulic control circuit is controlled by electric control loop.
