Description
Technical field
The present invention relates to flap-type grab bucket, more particularly to a kind of flap-type grab bucket blanking detection and protective device and installation method.
Background technology
Lifting equipment, such as bridge crane, gantry crane, portal crane, in some bulk material stock grounds or rubbish
Flap-type grab bucket crawl material need to be equipped with when using in the garbage storing hole of rubbish burning power plant to be carried.
Since crane cabin is located at fixed position, and bulk cargo is aerial lift device with crane, and the speed of service is fast,
Ambient light is weak, eye-blurred when, driver can not judge that grab bucket apart from material distance, cannot correctly be implemented to subtract in advance
Speed cannot stop in time after causing grab bucket to fall on irregular bulk material surface.
The grab bucket of such flap-type cannot such as be stopped in time on falling on material, steel wire rope and cable may be transferred excessively,
Cause steel wire rope or cable that job-hopping accident occurs, causes the damage of steel wire rope, cable;If excessive velocities when landing, once it falls
Onto slope, then landslide, rolling, damage grab bucket and steel wire rope, cable can occur.
Although there are many sensors on crane, such as can be by the load weight of detection steel wire hang, in weight
It is automatically stopped grab bucket when less than certain numerical value to decline, but stops needing one section of deceleration distance due to decelerating to, so still cannot
This is solved the problems, such as well;For another example although crane is able to detect that the distance that grab bucket declines, but can not judge that object is arrived in grab bucket
The actual distance of charge level can not provide prompt of accurately slowing down.
