Description
Technical field
The utility model is related to a kind of roll change buggy of automatic lifting.
Background technology
The raw materials for production of cold rolling mill are cold rolled strip coil, need to change intermediate calender rolls, in two during belt steel rolling
Between roller and working roll, often roll up operation when be required for repeatedly changing roller.During existing each roll change, need people with crow bar by roller
Son lifts, and another person takes out roller.There is the potential safety hazard of crow bar slippage, waste time and energy simultaneously, be unfavorable for the lifting of operating rate.
Utility model content
Technical problem to be solved in the utility model is：The safety existing during a kind of frequent roll change of solution is provided
The roll change buggy of the automatic lifting of hidden danger and roll change difficult problem.
For solving above-mentioned technical problem, the technical scheme that the utility model is adopted is：A kind of roll change of automatic lifting is little
Car, including vehicle frame, bottom of frame is provided with four rolling, and vehicle frame is provided with hydraulic cylinder, and the piston rod end of hydraulic cylinder is provided with lifting
Platform, the support being respectively provided on two sides with a pair of scissor shape arrangement of hoistable platform, the upper end of each pair support is connected to lifting
The two ends of platform corresponding side, lower end are connected to the two ends of vehicle frame corresponding side, and the middle part of each pair support is passed through rotational pin and is connected
Connect, the inlet of hydraulic cylinder is sequentially connected with oil pump and fuel tank by inflow pipeline, the oil-out of hydraulic cylinder passes through oil returning tube
It is connected with the oil return opening of fuel tank, oil returning tube is provided with pressure-relief valve, pressure-relief valve is provided with and controls unloading of pressure-relief valve on off state
Pressure handle.
As a kind of preferred scheme, described inflow pipeline is provided with relief valve, and the pressure relief opening of relief valve passes through relief tube
Road is connected with fuel tank.
As a kind of preferred scheme, described oil pump is pedal oil pump.
As a kind of preferred scheme, described hoistable platform be respectively provided on two sides with striker plate.
As a kind of preferred scheme, the width of described hoistable platform is more than four times of roller diameters.
As a kind of preferred scheme, described release handle end is provided with C-shaped bending section, near end on C-shaped bending section
Place is provided with Anti-slip cover.
The beneficial effects of the utility model are：The hoistable platform height adjustable of this roll change buggy, permissible when roller is taken out in operation
There is provided reliable support, can deposit temporarily changing and prepare the roller changed so that during roll change can one man operation, reduce behaviour
The number and simultaneously convenient and strength-saving made, can improve security and the operating efficiency at scene.
Because described inflow pipeline is provided with relief valve, the pressure relief opening of relief valve is connected with fuel tank by relief pipeline,
Can be with releasing pressure automatically when hoistable platform is overweight.
Due to oil pump for pedal oil pump so that operating personnel can easily control the height of hoistable platform according to field condition
Degree.
Striker plate is respectively provided on two sides with due to hoistable platform, prevents roller from tumbling, using safer.
Because release handle end is provided with C-shaped bending section, C-shaped bending section is provided with Anti-slip cover near end, is more convenient for
Operating personnel exert a force.
