【Brief description of the drawings】
Fig. 1 is parking of the present invention and the structural representation of handling interlock system.
【Embodiment】
The invention will be further described with embodiment below in conjunction with the accompanying drawings.
A kind of parking of the present invention and handling interlock system, including source of the gas 1, first switch device 2, second switch device 8, stay
Car system and handling system, the parking system and the handling system are connected by pipeline with the source of the gas 1 respectively, and described
One switching device 2 is arranged on the pipeline between the parking system and the source of the gas 1, and the parking system includes brake chamber
4 and quick release valve 3, the quick release valve 3 is arranged on the pipeline between the brake chamber 4 and the first switch device 2, described
Handling system includes the master switch 9 for being used to control handling, and the air inlet 91 of the master switch 9 passes through pipeline and the source of the gas
1 is connected, and the control mouth 92 of the master switch 9 is connected by pipeline with the gas outlet 83 of the second switch device 8, and described the
First air inlet 81 of two switching devices 8 is connected by pipeline with the source of the gas 1, the control mouth 82 of the second switch device 8
It is connected by the pipeline between pipeline and the first switch device 2 and the quick release valve 3.
During loading and unloading oils, press first switch device 2 and switch, be at closed mode, the gas of source of the gas 1 can not pass through
One switching device 2 is supplied into brake chamber 4 to brake chamber 4, and quick release valve 3 is deflated to the gas in brake chamber 4, system
Take offence room 4 spring cavity spring elongation, realize parking braking, meanwhile, in the pipeline between first switch device 2 and quick release valve 3
There is no air pressure, second switch device 8 is remained off, being normally carried out for charge and discharge operations can be realized by master switch 9.
After the completion of loading and unloading oils, when vehicle is travelled, no matter whether master switch 9 closes, and must open first switch device 2 and open
Close, be at open mode, the gas of source of the gas 1 enters brake chamber 4 by first switch device 2, and gas enters braking gas
The spring cavity compression spring of room 4, releases parking braking, and vehicle can be travelled, meanwhile, between first switch device 2 and quick release valve 3
Pipeline ventilation, gas enters the control mouth 82 of second switch device 8, and air pressure promotes second switch device 8 to commutate, and gas is from the
One air inlet 81 enters and eventually enters into the control mouth 92 of master switch 9, realizes the function of cut-out master switch 9, all handling
Switch is closed, so as to realize the interlocking of parking system and handling system.What deserves to be explained is, the present invention is not filled to first switch
Put 2 and be in open mode, then the pipeline ventilation between first switch device 2 and quick release valve 3, first switch device 2, which is in, closes
State, the then pipeline stuffiness between first switch device 2 and quick release valve 3 is defined, only at explanation first switch device 2
When both states are opened and closed, the pipeline between first switch device 2 and quick release valve 3 can be to that should have ventilation and stuffiness
Both states occur.Therefore, also first switch device 2 can is closed, then first switch device 2 and quick release valve 3
Between pipeline ventilation, first switch device 2 is in open mode, then the pipeline between first switch device 2 and quick release valve 3 is not
Ventilation.Final purpose is to realize the interlocking of parking system and handling system.
Thus, in loading and unloading oils, braked without the simple brake by tractor, parking and handling of the invention is mutual
Lock system can also provide parking braking, so that it is guaranteed that tank car vehicle body when loading and unloading oil plant and other items remains static, it is to avoid
Vehicle is sailed out of, brought risk of slipping away, therefore parking braking effect is more preferably, and loading and unloading oils are more stable, safety.Importantly, this
The parking of invention provides the interlocking of parking system and handling system with handling interlock system, and charge and discharge operations normally enter during parking
OK, charge and discharge operations terminate and when vehicle must be travelled, after parking braking is released, and the master switch of coordinated signals handling, which is in, closes
State, so that oil leak, gas leakage when avoiding handling and travelling, significantly reduce security risk.
In the present embodiment, parking of the invention is arranged at the discharge box (not shown) of tank car with handling interlock system
Interior, the parking also includes linkage (not shown) with handling interlock system, and the chamber door of the discharge box passes through the connecting rod
Mechanism is connected with the first switch device 2.When chamber door is opened, the first switch device 2 that links is closed, and is stayed so as to provide
Car is braked.When chamber door is closed, the first switch device 2 that links is opened, so as to release parking braking, is simultaneously closed off master control and is opened
Close 9.
Thus, acted on by the linkage of linkage, without manually operated first switch device 2, it is only necessary to pass through chamber door
Push And Release, then realize corresponding parking braking, release parking braking and close the function such as master switch 9, it is to avoid maloperation,
Improve efficiency.
In the present embodiment, the handling system also includes the first emergency cut-off threshold switch 6 and the second quick action emergency valve
Switch 7, the second switch device 8 also includes the second air inlet 84, and second air inlet 84 passes through pipeline and described second
