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.

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
