Description of drawings
Fig. 1 is structural representation of the present utility model.
Fig. 2 is hydraulic control system schematic diagram described in the utility model.
Among the figure: 1-guide rod device, 2-push pedal, 3-cross traveling trolley, 4-sideslip oil cylinder, 5-rail bracket, 6-lift arm, 7-lift cylinder, 8-joint link lever, 9-lifting crossbeam, 21-Hydraulic Station, 22-traversing control valve platform, 23-lifting control valve platform, 24-computer-controlled operation chamber.
The specific embodiment
Below in conjunction with drawings and Examples the utility model is further specified.
Referring to Fig. 1 and Fig. 2, a kind of steel plate automatic alignment device comprises lifting device, Traverse Displacement Unit and hydraulic control system, and described lifting device is located at the conveyor roller below, and every group of lifting device has 4 lift arms 6 and 2 hydraulic cylinders; Uniform free roller wheel on the lift arm 6, a side of lift arm 6 are to swing fulcrum, are installed on the roller bed frame, and another bogie side frame is promoting on the crossbeam 9, promotes crossbeam 9 and is connected with lift cylinder 7 by joint link lever 8 and bearing; Before the steel plate centering, first steel plate is mentioned by lifting device, make steel plate and roller-way emaciated face from, to avoid steel plate scratch in moving process.Lift cylinder 7 band displacement transducers by proportional solenoid valve control, can be realized handling with care.
Described Traverse Displacement Unit is located at the both sides of conveyor roller, formed by parts of appliance such as guide rod device 1, push pedal 2, rail bracket 5, sideslip oil cylinder 4, cross traveling trolleys 3, guide rod device 1 play the guiding role, anti-thrust plate 2 tilts, sideslip oil cylinder 4 and cross traveling trolley 3 are connected by bearing pin, push pedal 2 is fixed on the cross traveling trolley 3, and cross traveling trolley 3 moves forward and backward in rail bracket 5; Sideslip oil cylinder 4 band displacement transducers by proportional solenoid valve control, can be realized the control of automatic width and thrust, avoid bad steel plate of the excessive folder of thrust.
Lifting device and Traverse Displacement Unit pairing are used, and the length of every group of lifting device is 8 meters, for satisfying the production requirement of different steel plate length centerings, 2 groups, 3 groups, 4 groups lifting devices can be set, and Traverse Displacement Unit too.When steel plate length during less than 8 meters, realize the centering operation with one group of lifting device and one group of push unit; When the length of steel plate during greater than 8 meters (8-15 meters), then realize the centerings operation with two groups of lifting devices and two groups of push units, by that analogy.
