Abstract
The utility model relates to a ground surface paver, particularly to a full hydraulic plastic cement running track paver. The utility model comprises a caterpillar band walking chain wheel and a paving device at the time of paving and a walking rubber wheel at the time of hauling, wherein left and right driving systems of the caterpillar band walking chain wheel use independent oil motors, and two ends of each of the oil motor are connected with flow valves in parallel. The lifting movement of the paving device and the walking rubber wheel is realized through the transmission connection of a template, the direction of the movement is opposite, and the template is driven by using an oil cylinder. Every action of the utility model forms a full hydraulic stepless speed changing mode, driving force is big, and paving speed is even and stable. The utility model has the advantages of reliable action, compact structure and low cost and can ensure the quality of laying a running track.

The specific embodiment
Embodiment: as Fig. 2, all-hydraulic plastic cement race track paver shown in Figure 3, walking rubber tire 16 when comprising crawler travel sprocket wheel 18 when paving, flattener 15 and haul, as shown in Figure 1, walking sprocket wheel 18 drive systems adopt two independently oil motors 4 about crawler belt, and each oil motor 4 two ends also is connected to flow valve 5; 3 two ports of the turnover oil-piping of crawler travel chain wheel drive system oil motor 4 and reversal valve are connected, and two other port of reversal valve 3 connects hydraulic pump 1 and fuel tank 19 respectively.
The elevating movement of flattener 15 and walking rubber tire 16 be in transmission connection by master plate 13 and the direction of motion opposite, master plate 13 adopts oil cylinders 8 to drive.As shown in Figure 1,9 two ports of the turnover oil-piping of oil cylinder 8 and reversal valve are connected, and one the tunnel link to each other with hydraulic pump 1 in the reversal valve 9 other two-port, another road is connected with fuel tank 19 through flow valve 10.The oscillating deck of flattener 15 adopts oil motor 7 to drive, and is in series with flow valve 6 on oil motor 7 oil inlet pipes, and oil motor 7 flowlines are connected with fuel tank 19.
Oil motor and oil cylinder all adopt same set of hydraulic pump 1, also are provided with the overflow valve 2 that can control whole hydraulic system pressure between hydraulic pump 1 flowline and the fuel tank 19.
Whole hydraulic system is installed in fuselage 14 inside, during work, utilize rubber tire 16 that equipment is dilatory to the work-yard, handle electrical appliance button, make motor 17 drive hydraulic pump 1 and rotate, oil suction from fuel tank 19, pressure oil at first enters oil cylinder 8, and piston actuated master plate 13 moves, and promotes 16 of two rubber tires by two ends hinge bar and rotates around each self-supporting respectively, rubber tire 16 rises, and fuselage moves down; Flattener 15 drops to the operating position around its rotating shaft under leverage simultaneously.The rising or falling speed of rubber tire 16 and flattener 15 is controlled by the flow valve on the control valve piece 11 10.Subsequently, pressure oil drives two oil motors 4 and drives 18 rotations of two sprocket wheels respectively, drive the chain crawler belt and realize the work walking of equipment, the speed of walking is controlled respectively by two flow valves 5, realizes the synchronous walking or the divertical motion of equipment by the rotating speed of control oil motor 4.Oil motor 7 drives the plate that shakeouts of eccentric block driving flattener 15 bottoms and moves, and its hunting frequency is realized by the rotating speed of control oil motor 7 by flow valve 6.
