Abstract
The utility model is related to the gas control limiting device that a kind of bilateral overturns, vehicle frames（4）Upper fixed oil cylinder（7）, oil cylinder（7）Top is fixed on compartment（5）Bottom, it is characterised in that：Vehicle frame（4）The left and right sides is arranged with left valve seat（2A）With right valve seat（2B）, left valve seat（2A）It is equipped with left limit valve（1A）, right valve seat（2B）It is equipped with right limit valve（1B）, left limit valve（1A）Left gas outlet b and right limit valve（1B）Right air inlet c tracheaes（6）Connection, compartment（5）Bottom left welds left limit plate（3A）, right side welding right limit plate（3B）.Oil circuit is controlled by way of gas control, after vehicle /V, the hydraulic oil in the moment oil circuit that the gas of gas circuit is cut off is controlled to be also turned off, so as to play position-limiting action；Meanwhile only have an oil pipe to realize that fuel feeding and oil return, oil circuit are fairly simple in oil circuit.
Description
Technical field
The utility model is related to vehicle manufacture fields, are specifically the gas control limiting device that a kind of bilateral overturns.
Background technology
Bilateral overturns all by oil circuit /V at present, needs to increase an oil return pipe in oil circuit, oil inlet pipe and oil return pipe it
Between increase a lever limit valve, into and out of oil pipe, lever limit valve upper end steel wire rope connects the connection of limit valve both ends with compartment
It connects, when compartment is lifted to defined angle, lever limit valve is pulled open by steel wire rope, and hydraulic oil directly passes through limit valve from oil inlet pipe
Oil return pipe is flowed to fuel tank, oil cylinder is not entered back into, so as to play position-limiting action.Such structure oil circuit is more complicated, and works as and supply
When oil mass is big, hydraulic oil cannot return to fuel tank by limit valve completely, some oil, which also has, enters oil cylinder, so /V
Effect is not so good.
The content of the invention
The technical problem to be solved by the utility model is to provide the gas control limiting devices that a kind of bilateral overturns.
The utility model solves its technical problem using following technical scheme：The gas control limiting device that a kind of bilateral overturns,
Oil cylinder is fixed on vehicle frame, oil cylinder top is fixed on car bottom, it is characterised in that：Be arranged at left and right sides of vehicle frame left valve seat and
Right valve seat, left valve seat are equipped with left limit valve, and right valve seat is equipped with right limit valve, the left gas outlet b and right limit of left limit valve
The right air inlet c of valve is connected with tracheae, welding left limit plate on the left of car bottom, right side welding right limit plate.Left air inlet a connects
Welding system manipulates valve, right gas outlet d connections system control valve.
The position of the left limit plate is corresponding with left limit valve；The position of right limit plate is corresponding with right limit valve.
The beneficial effects of the utility model are：Oil circuit is controlled by way of gas control, after vehicle /V, controls gas circuit
Hydraulic oil in the moment oil circuit that gas is cut off is also turned off, so as to play position-limiting action；Meanwhile there was only an oil pipe in oil circuit
Realize that fuel feeding and oil return, oil circuit are fairly simple.
Description of the drawings
Fig. 1 turns over schematic diagram for the utility model left side；
Fig. 2 turns over schematic diagram for the utility model right side；
Fig. 3 is the oil of vehicle, pneumatic diagram；
In figure：1A-left limit valve, 1B- right limit valve, the left valve seats of 2A-, the right valve seats of 2B-, 3A- left limit plates, the right limits of 3B-
Position plate, 4- vehicle frames, 5- compartments, 6- tracheaes, 7- oil cylinders.
Specific embodiment
The utility model is described in further detail below in conjunction with the accompanying drawings.
As shown in Figs. 1-3, the power takeoff of vehicle is opened, drives oil pump for embodiment 1, and oil is supplied to control valve by oil pump, is controlled
Oil in valve directly returns to fuel tank from oil return opening；It turns on one's side to the left, hand control valve, which pushes, lifts position, and the compressed air in gas bag is led to successively
It crosses manipulation valve, limit valve, to control valve, promotes the spool of control valve, the oil inlet for making control valve and the hydraulic fluid port phase for being connected oil cylinder
Logical, hydraulic oil enters oil cylinder, and when compartment 5 gives rise to defined angle by oil cylinder 7, left limit plate 3A is pushed up to 1 A's of left limit valve
Top, cuts off the flowing of gas in left limit valve 1A, the spool return of control valve, and the hydraulic oil for supplying control valve is passed straight back to
Fuel tank, no longer to oil cylinder fuel feeding, so as to play position-limiting action.When vehicle declines, hand control valve pushes lower decrease, the compression in gas bag
Air, which passes sequentially through, manipulates valve, limit valve, to control valve, and negative direction promotes the spool of control valve, make the oil return opening of control valve with
The hydraulic fluid port of connection oil cylinder communicates, and the hydraulic oil in oil cylinder is pressed back into fuel tank under the action of big case gravity by former road.
