The utility model discloses a theory of operation and working process as follows: firstly, the ground is processed to be flat, then the hydraulic turnover plate 2 of the chassis 1 is integrally placed on the ground, and the chassis 1 is fixed on the ground. At the moment, the foundation pit groove does not need to be excavated on the ground and is used as an infrastructure for installing the base, so that the work of constructing the foundation pit groove is avoided.
As shown in fig. 1-9: in an initial state, the hydraulic turning plate 2 stops above the chassis 1 in parallel, a transport vehicle drives into the platform according to the arrow direction in fig. 1, and the wheel position at the vehicle head is fixed by the vehicle head wheel fixing block 9.
The headstock wheel fixing blocks 9 are two wheel stoppers which are spaced at a certain distance to clamp the headstock wheels.
After the vehicle is stopped stably, the front wheel stopper 4 and the vehicle body wheel stopper 5 work simultaneously, the two symmetrical wheel stopper oil cylinders 42 of the front wheel stopper 4 push the frame body 411 to extend forwards, and the connecting plate 45 drives the guide rod 46 to extend out of the wheel stopper frame 44 until the frame body 411 clamps the front wheels. When the guiding rod 46 extends out, the roller 412 is driven to rotate around the roller shaft 414, and the rolling friction between the guiding rod 46 and the roller 412 is beneficial to protecting the guiding rod 46 and reducing the abrasion.
The first body blocker 51 and the second body blocker 52 of the body blocker 5 operate simultaneously, that is: the first left body wheel stopper cylinder 512 pushes the first left baffle 511 to extend forwards, and the first right body wheel stopper cylinder 514 pushes the first right baffle 513 to extend forwards; the second left body chock cylinder 522 pushes the second left stop 521 to extend forward, and the second right body chock cylinder 524 pushes the second right stop 523 to extend forward. When the vehicle body wheel stopper oil cylinder extends out, the corresponding electromagnetic directional valve 621 is opened in an oil supply state, and the hydraulic control one-way valve 622, the pressure transmitter 623 and the one-way throttle valve 624 work in a matched mode to jointly push the vehicle body wheel stopper 5 to clamp the vehicle body wheel.
As shown in fig. 10-14: the PLC system sets the in-place pressure I and the pre-tightening pressure II of each gear device. When the actual clamping pressure reaches the in-place pressure I, namely the vehicle head wheels and the vehicle body wheels are clamped, the vehicle body wheel stopper 5 automatically stops, the lifting hydraulic cylinder 3 extends to drive the hydraulic turning plate 2 to laterally and quickly lift, and the shaft seat 7 rotates around the rotating shaft 8 to unload. The materials are unloaded and enter a material storage pit prepared in advance on one side of the chassis 1 or laid color stripe cloth to store or receive the materials.
In the discharging process, if the detected clamping pressure value is lower than the pre-tightening pressure II, the PLC system controls the front wheel stopper 4 and the body wheel stopper 5 to work simultaneously again, the clamping is automatically carried out, and the automatic stop is carried out when the pressure value reaches the in-place pressure I. After the materials are completely discharged, the lifting hydraulic cylinder 3 contracts to drive the hydraulic turning plate 2 to descend to the initial position, the wheel stopper oil cylinder drives the vehicle head wheel stopper 4 and the vehicle body wheel stopper 5 to reset, and the vehicle moves out of the hydraulic turning plate 2.
