One rotates with the rocking arm that valve block shaft is connected, and then realizes the closing of braking valve block, is unloaded when manipulating compressed air pressure in cylinder
It goes, braking valve block is realized under engine back pressure effect to be resetted, and band moving valve plate shaft rotates in turn, and then pushes rocking arm
Rotation, and realize the reset of piston push rod;It manipulates cylinder tail portion to be fixed on manipulation cylinder support plate by removable pin, whole process,
Manipulating cylinder can be as the change of working condition be by the component along rocking arm axis direction, and constantly deflects.
The main failure of current exhaust brake valve is to manipulate cylinder hair fastener, piston eccentric wear, manipulate cylinder gas leakage, piston O-ring mill
The reasons such as damage, auxiliary connection looseness, these failures are largely and the stress shape of current most of exhaust brake valve operating mechanisms
State is related.Current many exhaust brake valves manipulate cylinder tail portion and are hinged with holder, and piston push rod is hinged with rocking arm, and point of interface is opposite to be transported
Dynamic excessive, reliability substantially reduces;All kinematic pairs are fully exposed in external environment, and the external environments factor such as dust, steam all adds
The failure of acute kinematic pair;In the case of the push rod of cantilever beam structure is by larger vibration in the course of work, auxiliary connection loosening, each component
The failures such as abrasion further deteriorate;Further, since the presence of rocking arm so that manipulating cylinder push rod is executing being turned on and off for valve block
When, suffered power and piston push rod axis are misaligned, and there are transverse components, be easy to cause piston or piston O-ring eccentric wear, into
And causes to manipulate cylinder gas leakage and manipulate the failures such as cylinder hair fastener.

A kind of closed shock type exhaust brake valve operating mechanism of the design, specially a kind of gear containing spring bearer plate and idler wheel
The braking valve operating mechanism of rack driving pattern manipulates cylinder end and is fixedly connected with rack, brake valve valve block shaft is a gear
In addition axis designs a gear and is mounted on the common mounting hole for manipulating cylinder, support plate and valve body as idle pulley, rack and pinion
Axis and idle pulley are intermeshed simultaneously, constitute two pairs of gear pairs, are manipulated cylinder tail portion bolt and are fixed.Cylinder push rod is manipulated in compressed air
Effect is lower to stretch out, and rack is moved along piston push rod axis direction, and is rotated with movable gear shaft, and opening for braking valve block is further realized
It opens and closes;Idle pulley is mounted on idler shaft, and is connected by needle bearing, and idler shaft is connected with valve body mounting hole by screw thread
It connects, idle pulley plays the role of improving piston push rod stress, ensures that Impact direction is overlapped with the axis of piston push rod always, living
The effect that moment of flexure is not present in push rod is filled in, the eccentric wear for improving piston and hair fastener situation are conducive to;The fixed manipulation cylinder in tail portion prevents
The phenomenon that conventional hinge structures cause looseness because of abrasion.
A roll wheel assembly is fixed below rack so that rack be moved forward and backward when below have certain supporting role,
Convert cantilever beam structure to simple beam structure, avoid because cantilever beam structure there are due to lead to piston vibration serious wear, and
Ensure the good engagement condition of rack-and-pinion.Resilient balls pressing plate is installed in rack upper surface, bullet is installed in pressing plate interstitial hole
Spring and ball, rack upper surface open up circular scrolling groove, and ball is pressed in a groove under the action of the spring, and one end of pressing plate is logical
It crosses screw and is fixed on idler shaft upper surface, the other end of pressing plate is sleeved on gear shaft, and is limited by clamp spring;The work of spring bearer plate
With being to remain a precompression to rack, improve its vibration state, rackwork stable movement advantageously ensures that system
Reliability.
Entire operating mechanism is encapsulated in by the cover to be manipulated in cylinder support plate, is had rubber sheet gasket between the cover and support plate, is made
Be isolated with external environment, be conducive to the entrance for preventing the impurity such as dust, prevent kinematic pair wear out failure, ensure the reliable of system
Property.
To sum up, the design has the following advantages that:(1)The mechanism reduces the connection of transmission revolute pair, reduces traditional machine
Structure leads to the failure of handle structure because of excessive revolute pair abrasion;(2)The mechanism improves the force-bearing situation of piston push rod, makes
Piston push rod stress is overlapped with its axis, reduce traditional mechanism during the work time the presence of moment of flexure and lead to the mill of piston
The occurrence of damaging situation aggravation, and then leading to hair fastener or gas leakage;(3)The support of rack underside roller and upper spring bearer plate ensure
Piston push rod smoothly moves, and plays the role of antivibration, converts the piston push rod of cantilever beam structure to simple beam structure, carries
The high vibration resistance of piston push rod;(4)It is entire to execute traditional operating mechanism by rubber pad box bonnet seal, with external environment every
Absolutely, the working environment for improving executing agency, by the reliability for the system that greatly improves;(5)The entire cylinder that manipulates passes through bolt and sealing
Bushing is completely fixed with support plate, without relative motion, is avoided between traditional cylinder and support plate because there are relative motions to lead
It causes cylinder force-bearing situation bad and the abrasion of tail portion rotational pin and causes to fail;(6)It is simple in structure and compact, it is easier to reality
It is existing.
