Property plate between be provided with limit switch, the lower section of described baffle plate upper bumper is provided with displacement transducer, and described displacement passes
Sensor and limit switch connect controller, and described controller connects power supply and brake, described power supply and brake
It is connected with walking mechanism, the crane girder at described walking track two ends is respectively arranged with backstopping assembly.
Fix between described baffle plate and trolley frame and be connected.
The cross sectional shape of described elastic plate is arc mechanism.
Described baffle plate is identical with the width of trolley frame with the length of elastic plate.
Described buffer is uniformly distributed between elastic plate and baffle plate.
Electrically connect between described displacement transducer and limit switch with controller.
Fix between described backstopping assembly and crane girder and be connected.
The beneficial effects of the utility model: in this utility model, the spacing and buffer unit of carriage walking is arranged at dolly
On frame, trolley orbits distance barrier or the backstopping assembly certain distance at guide rail two ends during work
Time, displacement signal is sent in controller by the displacement transducer on trolley frame, controller cut off what walking mechanism was connected
Power supply, starts the brake in walking mechanism so that trolley is the most out of service, when displacement transducer breaks down simultaneously
Time, elastic plate collides with barrier, thus triggers limit switch, simultaneously can be by the buffer of trolley frame rear and front end
Play certain cushioning effect, prevent the impulsive force suffered by trolley excessive；Total this utility model has simple in construction
Rationally, high safety, advantage easy to use.
