Beneficial effect
A kind of concrete polisher closed with centrifugation out of control of the present invention, when concrete polisher is out of control, engine
It will continue to bring power source for speed reducer, and kinetic energy is transmitted in smear by speed reducer, smear drive smears disk to concrete ground
Face spin friction, but since concrete polisher not opposite power out of control is come the friction for preventing ground from transmitting, cause to slow down
Kinetic energy feedback onto itself, so that speed reducer drives concrete polisher top half quickly to rotate, is generated centrifugal force by machine,
So that sliding block drives L-type mandril up to hit in centrifugation guide plate, L-type mandril strikes scattered power because under the action of centrifugal force
Push plate pushes plate by pulley driving Z-type gag lever post one end toward right rotation until being stuck on centrifugation frame inner wall, Z-type limit so that dissipating
The position bar other end has unclamped the limitation to fixed ring, and the elastic force that fixed ring utilizes third spring to generate pops up telescopic rod, stretches
Bar drives arc push plate to pass through through hole and operating stick is pushed away L-type baffle, so that operating stick drives igniter break trigger line, allows
Concrete polisher stops rotating；It resets operation: stirring one end that release link is exposed toward moving left, and the release link other end
Fixed ring is then squeezed toward moving right, allows fixed ring that telescopic rod is driven to reset, release link is turned left when stirring, and will drive compression bar to sticking up bar
The promotion of one end allows and sticks up bar other end promotion Z-type gag lever post lower end, Z-type gag lever post is avoided to block the reset of fixed ring.
Compared with prior art, the beneficial effects of the present invention are: concrete polisher out of control due to itself kinetic energy by
Under be transmitted to, and generate centrifugal force, by limitation of the slipper push Z-type gag lever post to release mechanism on centrifugal mechanism, allow
