Dynamic, wire rope gearing, V belt translation or similar transmission.
The working principle of the invention and process:
Present invention employs a kind of system -- soft or hard support coupling apparatus for controlling telescopic spring amount, and using limitation cleaning machine
The method of structure corner amplitude-support follower.
The system for controlling telescopic spring amount -- the course of work of soft or hard support coupling apparatus is as follows: freeway guardrail cleaning
Vehicle is when working normally or passing through notch, variation due to highway barrier to wiper mechanism counter-pressure, by make to be connected with screw rod
The length of big spring changes, the position sensor and trigger switch control according to big spring stroke, on controller mounting plate
System processed issues signal, controls electric motor starting or shuts down, motor drives feed screw nut by transmission gear, due to screw rod spiral shell
Female fixation, screw rod are rotated and are moved, to realize the adjusting of screw rod displacement；At the same time, one, spring passes through guiding pin
It is connected with screw rod, in addition one is connected in front support swing arm by spring mounting cylinder, and the variation of screw rod length will also realize bullet
The variation of spring displacement, when spring stress is excessive, its stroke close to one group of sensor the upper limit when, sensor issue instruction,
To control motor action, rotates the feed screw nut engaged with screw rod towards a direction, keep screw rod elongated, conversely, working as spring
Stress is smaller, its stroke close to one group of sensor lower limit when, sensor issues instruction, to control motor action, make with
The feed screw nut of screw rod engagement is rotated towards other direction, so that screw rod is shortened, by the variation of motor control feed screw nut's rotation direction, is made
Screw rod is elongated or shortens and counterbalance spring stress is excessive or too small, keeps telescopic spring amount in a certain range.
In general, the flexible of spring is controlled in variation in very narrow range, to guarantee to swing model to support swing arm in work
The requirement for enclosing variation is supplemented by the length variation of screw rod.Due to spring cannot moment occur big displacement variation, thus
It cannot make that swing arm generation is supported quickly to pull back, avoid cleaning vehicle wiper mechanism when passing through notch and cleaned by clamping, guardrail
The wiper mechanism of vehicle and support swing arm are hinged, by the buffer adaptation wiper mechanism coupled with rear support swing arm, adapt to guardrail
The variation on surface, when cleaning vehicle passes through notch, the regulatory function of the buffer increases a possibility that wiper mechanism is by clamping.
Method-support follower the course of work for controlling wiper mechanism corner amplitude is as follows:
For cleaning vehicle in the cleaning course of work, the track of cleaning vehicle movement and guardrail are substantially parallel, but its with guardrail away from
It is different from possible, in this way, the swing arm of cleaning vehicle front support and rear support swing arm are opposite possible different from the pivot angle of guardrail, to keep clear
The cleaning of washing machine structure adapts to the variation, one in direction substantially parallel with vehicle traffic direction of the working range of wiper mechanism
In range, and it is able to achieve local adjustment and fluctuation.
For the relation of following up for realizing support swing arm corner and arc frid corner, which passes through fixation determining on a mounting board
The gear drive of gear, transition gear and follower gear composition, drives active drive sprocket wheel and driven drive sprocket, driven driving
Sprocket wheel drives arc frid to be moved, and is changed with meeting the swing arm of cleaning vehicle front support and the opposite pivot angle with guardrail of rear support swing arm
When, the cleaning of wiper mechanism also adapts to the variation.
Arc frid between arc-shaped slot and the locking plate on wiper mechanism with locking pin by being coupled, arc frid and installation
Driven drive sprocket on rear support arm shaft is fixed, and is driven by it, when Cleaning vehicle for guardrail passes through notch at work,
The rotational angle of wiper mechanism will be limited by the fluting space of arc groove, reduce the possibility that wiper mechanism is destroyed by clamping；And
In normal work, when supporting swing arm to swing, which will drive driven drive sprocket by follower, to make arc
The change in location of frid, the movable spatial position of the locking pin in arc groove also will variation, in the movable of locking pin
In the range of space, by the swing for the buffer adaptation wiper mechanism that rear support swing arm couples, wiper mechanism is made to adapt to guardrail table
The variation in face unclamps lock pin and fixed pin folds up front support swing arm and rear support swing arm after use.
