And be related to be applied to the method for controlling security of the safety control of this vehicle body pipeline.
Background technology
The control system that vehicle body reciprocal transportation line uses at present, by multigroup complex function air relief valve (external pilot electromagnetism
Valve-type) control pipeline raising and lowering, adjust raising and lowering speed using precise pressure regulating valve, to prevent with overflow valve
Pipeline raises suddenly because of gas source air pressure, the too fast problem of the rate of climb.The shortcoming that this system exists is as follows: the first, conveys
When line is in a high position, pipeline is it sometimes appear that situation about automatically falling down.Reason be pipeline in a high position, using compound work(
In energy air relief valve, the function a part of source of the gas of pinning of envelope carrys out balanced transmission deadweight and realizes stopping, and this kind of function can only be satisfied with
Short period halted state, but the time one is long, because of the leakage of control valve itself and gas source pipe, destroys the balance pressure of system
Power, now pipeline deadweight can overcome the uncontrolled ground of source of the gas balance pressure automatically to decline.Secondth, pipeline, in low level, can go out
The situation of existing uncontrolled automatic rising, not only part of damage, or even there is overturn accident.Reason is in one galvanized pipe of this system
Source of the gas needs to empty when pipeline declines, and bleed pressure have to be lower than the deadweight of pipeline in low level；But work as certain
When stopping state in the valve element of group complex function air relief valve, compressed air can be scurried into the master of lifting cylinder by another galvanized pipe
In one galvanized pipe of trachea, and when the pressure scurrying into source of the gas reaches and can overcome pipeline gravity pressure, pipeline occurs as soon as
The situation of uncontrolled automatic rising, so there is larger potential safety hazard in system.

The security control thinking of the safety control system of vehicle body pipeline described in this example is: when vehicle body pipeline is located at a high position
When, the first galvanized pipe 5 is constantly in aeration status to compensate the pressure loss because leakage causes it is ensured that balance pressure is constant；When
When vehicle body pipeline is located at low level, the first galvanized pipe 5 is constantly in exhaust condition to discharge the source of the gas scurried in pipe in time, protects
Card overpressure is less than the deadweight of pipeline.
Described in this example, the control principle of the safety control system of vehicle body pipeline includes:
Pipeline lifts, and the left coil of electromagnetic valve 10 obtains electric, commutates to the work of left position, control source of the gas pass through the first logic or
The county road mouth p1 that valve 11 transmits control signals to Air pressure control release valve 7 promotes its valve element action so that gas source enters the first plating
Pipeline is promoted to rise in zinc pipe 5；
Pipeline is high-order to be kept, and when electromagnetic valve 10 commutates to left position work, source of the gas will be controlled to be transferred to Pneumatic valve 9 simultaneously
In pilot port and promote its valve element to commutate to the work of right position, depress high-order corresponding travel switch when pipeline gives rise to a high position
8, now, the position of travel switch 8 be high-order corresponding ls01 so as to be in normally off, control source of the gas pass through Pneumatic valve 9,
Travel switch 8(ls01) and the first logic or valve 11, pilot port p1 transmitting control signals to Air pressure control release valve 7 makes its valve
Core is constantly in open mode it is ensured that gas source can be supplied gas to the first galvanized pipe 5 always；

Pilot port p2 transmitting control signals to Air pressure control release valve 7 promotes its valve element action, the first galvanized pipe 5 aerofluxuss, pipeline profit
Bleed pressure is overcome to decline with deadweight；
Pipeline low level keeps, and when electromagnetic valve 10 commutates to right position work, source of the gas will be controlled to be transferred to Pneumatic valve 9 first simultaneously
Lead on mouth and promote its valve element to commutate to the work of left position, depress the corresponding travel switch of low level 8 when pipeline drops to low level,
Now, the position of travel switch 8, for the corresponding ls02 of low level so as to be in normally off, controls source of the gas by Pneumatic valve 9, OK
Cheng Kaiguan 8(ls02) and the second logic or valve 12, pilot port p2 transmitting control signals to Air pressure control release valve 7 makes its valve element
It is constantly in open mode it is ensured that the first galvanized pipe 5 is constantly in exhaust condition.
This example is passed through to increase other components of control valve group and its cooperation, when vehicle body pipeline is located at high-order, controls the
One galvanized pipe 5 is constantly in aeration status to compensate the pressure loss because leakage causes it is ensured that balance pressure is constant；When vehicle body is defeated
When line sending is located at low level, control the first galvanized pipe 5 be constantly in exhaust condition in time the source of the gas scurried in pipe being discharged it is ensured that
Overpressure is less than the deadweight of pipeline；This example Successful tests application on a few money body of a motor car pipelines of applicant, solution
Determining the problem of vehicle body pipeline uncontrolled automatic decline and rising when stopping line, thus avoiding the problem of part of damage, having increased
Add security function, eliminating the potential safety hazard causing injury to personnel of may overturning so that the safety control of described vehicle body pipeline
