Abstract
The invention discloses an inner and outer rack traveling crane mechanism, belongs to the technical field of hydraulic placing machines, and aims to provide the inner and outer rack traveling crane mechanism which is capable of realizing self walking through a hydraulic system. The technical proposal adopted for solving the technical problem is that two outer racks of the inner and outer rack traveling crane mechanism are oppositely arranged; an inner rack is arranged in the middle of the two outer racks and is connected with the outer racks through two thrust cylinders; relative movement of the inner rack and the outer racks can be generated by the two thrust cylinders through the expansion and contraction of the piston rods of the two thrust cylinders. According to the invention, the outer racks can move a distance of a thrust cylinder in the moving direction of the inner rack, that is, the moving distances of the outer racks and the inner rack are equal, when the piston rod of a rack rising oil cylinder is withdrawn, the inner rack falls back on the outer racks, the walking type forward movement of the inner and outer rack traveling crane mechanism can be realized through the repetition of the steps, and otherwise, the walking type backward movement of the inner and outer rack traveling crane mechanism can also be realized.

Summary of the invention
Outrigger driving mechanism in the present invention, overcomes the deficiency that prior art exists, provides a kind of interior outrigger driving mechanism relying on hydraulic system to realize self-moving type walking.
In order to solve the problems of the technologies described above, the technical solution used in the present invention is: interior outrigger driving mechanism, comprise internal frame, outrigger, internal frame base, interior slide cartridge, outer slide cartridge, propelling cylinder and rise frame oil cylinder, two outriggers are oppositely arranged, internal frame is positioned at the centre of two described outriggers, connected by two propelling cylinders between internal frame and outrigger, two described propelling cylinders produce relative displacement by flexible internal frame and the outrigger of can making of its piston rod;
Described interior slide cartridge and outer slide cartridge are also positioned at the centre of two described outriggers, outer slide cartridge is arranged on internal frame, described internal frame base is arranged on the bottom of interior slide cartridge, be provided with between internal frame base and outer slide cartridge and rise frame oil cylinder, the described frame oil cylinder that rises produces relative displacement by flexible internal frame base and the outer slide cartridge of can making of its piston rod;
The bottom of two described outriggers is provided with outrigger slideway, there is back-up block the bottom of outrigger slideway, the top of outrigger slideway is provided with block, the bottom symmetrical of described internal frame is provided with multiple axis of rolling, the end of the described axis of rolling is provided with scroll wheel, and described scroll wheel correspondence is arranged in outrigger slideway.
The cylinder body of described propelling cylinder is fixedly installed on described block, and the piston rod of propelling cylinder is fixedly installed on internal frame.
The beneficial effect that the present invention compared with prior art has is: in the present invention, internal frame is connected with outrigger by propelling cylinder, connect by rising frame oil cylinder between internal frame base and outer slide cartridge, when the piston rod rising frame oil cylinder is regained, because the cylinder body rising frame oil cylinder is fixed on internal frame base, the piston rod rising frame oil cylinder is fixedly installed outside on slide cartridge, when the internal frame be connected with outer slide cartridge bears a heavy burden, internal frame base is raised off ground, the piston rod now controlling propelling cylinder stretches out, cylinder body due to propelling cylinder is fixed on outrigger, the piston rod of propelling cylinder is fixedly installed on internal frame, internal frame is passed along outrigger the stroke that is passed oil cylinder by propelling cylinder, again control to rise frame cylinder action, namely the piston rod controlling to rise frame oil cylinder extends, internal frame base and internal frame generation relative displacement, make base and earth surface, continue to extend and rise the piston rod of frame oil cylinder until outrigger is pulled away ground by scroll wheel, now outrigger hangs on internal frame by scroll wheel, the piston rod controlling propelling cylinder is regained, outrigger just can move along the direction of motion of internal frame, and the also stroke of a mobile passing oil cylinder, namely outrigger is equal with internal frame stroke, when rising the piston rod withdrawal of frame oil cylinder, internal frame can drop on again on outrigger, repeat above-mentioned steps, the legged reach of the present invention can be realized, otherwise, also can realize step-by-step type to retreat.
