Description
Technical field
The utility model is related to a kind of for preventing vacuum soil pick-up tank body back door of vehicle lid from pushing up bad interlock extremely.
Background technology
Vacuum soil pick-up tank body vehicle is mainly used in the suction of the sewage, waste liquid, oil-cut mud of each production of plant area etc., fortune
Defeated and discharge, makes to obtain certain vacuum degree in tank body by manipulating vacuum pump, thus will be in soiling solution suction tank body, discharge, which has, to be added
Pressure is put, discharge two ways of flowing automatically.Since the sewage, waste liquid, oil-cut mud that are drawn into tank body generate deposited phenomenon, seriously
When can form bulk, by gravity flow and pressurised exhaust all cannot be clean by the residual drain of tank body, it usually needs jack up tank body
Open back door, by manually use spader, giant rinse the methods of, the residue in tank body could be cleaned out.
As shown in Figure 1, vacuum soil pick-up tank body back door of vehicle lid 1 is driven by being set on the locking cylinder 11,12,13,14 of quadrangle
Dynamic locking latch realizes locking, while rear door closure 1 is opened and closed by being set on the realization of pipe bending cylinder 21,22 of both sides, control
System processed is as shown in Fig. 2, vehicle power supply XDS passes through the first button switch AN and the second button switch BN respectively through switch SK
To the 3 position-5 way solenoid valve 2 of locking cylinder and the 3 position-5 way solenoid valve 3 of driving pipe bending cylinder is driven to control, driving lock
The 3 position-5 way solenoid valve 2 of locking oil cylinder and the 3 position-5 way solenoid valve 3 of driving pipe bending cylinder provide work air source simultaneously by gas receiver 4
Locking cylinder 11,12,13,14 and pipe bending cylinder 21,22 are controlled respectively through hydraulic valve bank 5, hydraulic valve bank 5 is by fuel tank 6
Hydraulic oil is provided with oil transfer pump 7.Its course of work draws good hand's braking, 8 public affairs are got in the air pressure of gas receiver 4 to start vehicle first
Jin or more, clutch is stepped on, vehicle power takeoff with engine power output shaft is combined, is loosened the clutch, power takeoff passes through company
Engine power is transferred to hydraulic pump 8 by connection mechanism, and oil transfer pump 7 is pumped out hydraulic oil and pressurizeed, passed by high-pressure oil pipe by hydraulic pump 8
Hydraulic valve bank 5 is delivered to, hydraulic valve bank 5 has commutation function, imports and exports direction change by external gas source, pushes hydraulic valve bank 5
Interior valve body changes the direction of the hydraulic oil output port of hydraulic valve bank 5, realizes high pressure liquid pressure oil commutation function；Three five
The gas circuit of three-way electromagnetic valve 2,3 has commutation function, is the variation that dead electricity is obtained by two end solenoid valve of valve body, inhales moving valve movement, changes
Become valve body airway path direction, so as to fulfill the control of locking cylinder 11,12,13,14 and pipe bending cylinder 21,22, locking cylinder
Door closure after driving locking latch locking or unlocking, door closure is opened and closed after pipe bending cylinder driving.
Above-mentioned control system is manipulated by driver in driver's cabin, after release back door cover locking bolt, jack-up tank body, opening
Door closure gets off and clears up residue in tank body.But in practical applications, often cover locking bolt does not discharge completely at back door
In the case of, door closure after opening frequently causes the part distortions such as tank body back door cover locking bolt mechanism, locking cylinder, rear door closure, draws
The events such as bad, fracture.It lacks a sense of responsibility mainly due to driver, confirmation of getting off is inadequate, maloperation, and the first button switch does not have
Releasing position is switched to, in the case where locking latch does not act, door closure after pipe bending cylinder is open-top；Simultaneously because vehicle operation
Environment is poor, and dust is big, there is little particle impurity in the compressed air of entrance, if into inside 3 position-5 way solenoid valve, causes valve
Core is stuck, akinesia, in addition the reasons such as spool deformation, valve body inner seal ring aging, can all cause to malfunction；Secondly it locks and inserts
Pin deformation, also can be stuck in the operating condition, and four position locking cylinders is caused to be unable to synchronous release in place；Since sealing ring is old
Change, have impurity in hydraulic oil, block distortion may also cause locking cylinder stuck.More than abnormal conditions can cause rear door closure,
The parts damages such as locking cylinder, pipe bending cylinder and connection structure, lead to faults frequent, it is therefore desirable to put into a large amount of personnel,
Time, spare part are repaired, and improve vehicle operating cost, and seriously affect the operating efficiency and serviceability rate of vehicle.
