Description
Technical field
The utility model is related to a kind of unpowered rollover stands with slow rotation function.
Background technology
The large-scale workpieces such as rocker arm of coal mining machine are frequently necessary to overturn when shifting installation is safeguarded or hung in processing, and when overturning generally requires
The side for being reversed workpiece is tangled using suspension hook, and workpiece could be overturn under the traction of overhead traveling crane.In general, large-scale or heavy workpiece turns over
Very strong impact and drag interaction can be generated to suspension hook chain sling, be also possible to that suspension hook is made to hang when serious when turning under the action of inertia force
Chain get rid of suddenly it is de-, operation scene there is larger security risks.
Invention content
The utility model is intended to overcome the shortcomings of above-mentioned prior art, provide it is a kind of operation it is safer, need not be equipped with it is dynamic
Power can rely on workpiece dead weight to realize the unpowered rollover stand that voluntarily can slowly rotate slowly overturn.
The utility model includes work rest, oscillating oil cylinder and oil cylinder fixing base, pipeline, reversal valve and throttle valve.Wherein, work
Part frame includes work piece holder, intermediate link and counterweight；The longitudinal direction that work piece holder upper center position is equipped with trapezoidal section is passed through
Logical notch；Both sides are the inclined-planes with certain slope in slot.Work piece holder is weldingly fixed on above intermediate link, and centre connects
Frame is connect to be weldingly fixed on above counterweight.Intermediate link is by installation screw on oscillating oil cylinder output shaft and is bolted to swing
On oil cylinder output shaft, oscillating oil cylinder is fixed on oil cylinder fixing base, and oil cylinder fixing base is installed on the ground.Reversal valve includes commutation
Valve A and reversal valve B, oil inlet and throttle valve one end of the oscillating oil cylinder ante-chamber hydraulic fluid port by piping connection in reversal valve A, throttle valve
The other end by piping connection in the oil inlet of reversal valve B, the oil return opening of reversal valve A and reversal valve B existed by piping connection
Oscillating oil cylinder back cavity hydraulic fluid port.The effect of work piece holder is to put workpiece for card, and under the gravity of workpiece itself, work rest turns over
After going to position stopping, workpiece can skid off trapezoidal notch along dovetail groove inclined-plane, and facilitate workpiece hangs shifting installation.
Throttle valve can adjust the flow velocity by throttling valve fluid by adjusting the size of latus rectum；Two reversal valves are
2/2-way, normally closed hand-operated direction valve.The output shaft of oscillating oil cylinder can rotate, without moving forward and backward.Swing oil
There is installation screw on the output shaft of cylinder, for connecting other workpiece.
Workpiece is positioned in the trapezoidal notch of work piece holder, and the front and back chamber of oscillating oil cylinder passes through pipeline, throttle valve, reversal valve
A hydraulic circuit is connected into, work piece holder slowly rotates under workpiece gravity, after work piece holder rotation to a certain extent,
Workpiece starts the trapezoidal notch along workpiece slot as rotation is slowly slided, and conveniently hangs.After workpiece is hung out, by reversal valve
A is connected, and work piece holder returns to original position under the action of counterweight.
The output rotation function of oscillating oil cylinder and the flow control function of throttle valve is utilized in the utility model so that hydraulic pressure
Velocity of medium in circuit is provided with controllability, that is, turns the flow area of restriction down, velocity of medium can be made to become smaller, that is, swung
Oil cylinder slows, that is, work rest realizes slow rotation under the action of workpiece gravity；Using with certain slope
Work piece holder, after making work rest inclination flip, workpiece can voluntarily slide under the effect of gravity along dovetail groove inclined-plane.Work rest with
Original position can be voluntarily returned under the action of weight, additional power need not be provided.Flow control may be implemented in throttle valve, passes through adjusting
The size of flow valve, control orifice flow area can adjust flow；Throttle valve is conventional throttle valve, that is, with double
To throttling function, model MG6G1.2.The model L30-42 of oscillating oil cylinder.
The utility model is suitable for larger work pieces process, lifting and the overturning of weight, and advantage one can be achieved on workpiece
Steady overturning, prevent workpiece from occurring larger impact force in overturning and generating danger；Second is that whole process does not need outside
Power can realize.
