The specific embodiment
The utility model can be used in combination with the body of wall rectification cutting machine of separate case application, carries out the body of wall cutting with the body of wall cutting machine, for the wall block that cuts down, carries and shift utilization with transport trolley.As far as possible near body of wall, make transport trolley bottom longitudinal support 1-1 be close to uncut fixedly body of wall, on the wall block of well cutting, make a call to two open-works in advance, be used for penetrating sliding sleeve 4-2, and installation drags baffle plate 4-10 and baffle plate locking piece 4-11 at the body of wall back side.Two wedge shape hook 2-9 of chain pull change-over panel 2-5 are articulated on the initial posting 1-7 of chain.Close the liquid return switch of hydraulic efficiency gear 4-7, under the effect of hydraulic power parts, the plunger body of hydraulic efficiency gear 4-7 can protrude upward, move on the pulling conduction chain 4-4, change pulling force into horizontal direction by last chain track adjusting wheel 4-9 and lower chain track adjusting wheel 4-6, and drag sliding shoe 4-1 and draw close to bottom transverse support 1-2.Because two wedge shape hook 2-9 of chain pull change-over panel 2-5 are articulated on the initial posting 1-7 of chain, so chain pull change-over panel 2-5 can not raise.On the hydraulic efficiency gear 4-7 plunger two go up the effect that chain track adjusting wheel 4-9 have formed movable pulley, sliding shoe 4-1 sliding distance is 2 times of height of plunger lifting.Owing to drag the effect of baffle plate 4-10, sliding shoe 4-1 drives sliding sleeve 4-2 indentation inwards, body of wall is gone up to bottom longitudinal support 1-1 moved.When sliding shoe 4-1 when the bottom transverse support 1-2, the pulling force change-over panel contact 4-5 on the sliding shoe 4-1 can link up with 2-9 to wedge shape and push away from initial posting 1-7.
At this moment, drag baffle plate 4-10 and arrived bottom longitudinal support 1-1 outward flange, body of wall has been dragged on the longitudinal support 1-1 of bottom.When the plunger body of hydraulic efficiency gear 4-7 rises, then can spur chain pull change-over panel 2-5 again, rotate around drive shaft 2-4, rise slightly simultaneously, drive the transport trolley rear portion and raise thereby drive car body lifting transmission arm 2-7 to rising; The rotation of drive shaft 2-4 simultaneously can drive transmission quarter butt 2-3 and rotate, and promote transmission stock 2-2 and advance forward by connecting rotating shaft 2-6, because flower wheel 3-1 is fixed on thrust and crooks one's arm on the 2-1, therefore the amount of travel of transmission stock 2-2 drives thrust and crooks one's arm 2-1 around connecting rotating shaft 2-6 rotation, and the drive transport trolley is anterior to raise.By the crank arm length of 2-1 of appropriate design car body lifting transmission arm 2-7, transmission quarter butt 2-3, thrust, can make vehicle before and after rise identical, realize support and carrying body of wall picking-up built on stilts on it.
After the body of wall built on stilts, the operator operates pedal and cripple 3-6 makes it to rotate, when pedal and cripple 3-6 drive chainlet dish 3-4 rotation, chainlet dish 3-4 drives big chain plate 3-3 by chain drive-belt 3-5 again and rotates, thereby driving drive wheel 3-2 rotates, promote flower wheel 3-1 again, make the transport trolley can forward-reverse.Move arm-rest frame 3-11 with hand, cooperate the vehicle seat twisting can drive drive wheel 3-2 and turn to, thereby transport trolley is turned.Appropriate design chain drum diameter can be realized making car with extremely slow speed motion with very little strength.
After body of wall is moved to new position, below body of wall, fill up the cushion block of proper height earlier between the longitudinal support 1-1 of bottom, open the liquid return switch of hydraulic efficiency gear 4-7 then, under body of wall and the effect of vehicle self gravitation, the plunger body of hydraulic efficiency gear 4-7 can downward indentation, and the vehicle whole height descends, baffle plate locking piece 4-11 with drag baffle plate 4-10 and lay down successively, just can remove vehicle and sliding sleeve from body of wall, carrying work is finished at this point.
