Hook.
Background technology
The cleaning of bridge crane track at present is that crampon is usually used to promote cargo to be handled
And transfer, the heavier mass of crampon, crampon includes pulley shield, pulley and suspension hook on pulley shield, lifting
Machine realizes the promotion of crampon by the transmission between steel cable and pulley, due in operation process at the scene, crampon
Volume is larger, heavier mass, and the oscillatory for lifting by crane steel cable is again larger, thus easily cause the collision of crampon and field device,
Or the collision with field worker, easily there is a situation where safety accident and damage field type facility.
Crampon belongs to rigid connection due to crampon when in use, and lifts by crane moment and generate huge impulse force, makes
Suspension hook goes down to be easy in this way to damage suspension hook for a long time directly by the impulse force of vertical direction, and make crampon uses the longevity
Life is seriously affected, and increases use cost, additionally, due to weight during handling it occur frequently that swinging, makes pulley shield
Junction cannot be mitigated the stress of horizontal direction by the impulse force of horizontal direction, make and since pulley shield belongs to rigid connection
It causes serious damage, and then influences its service life.
Invention content
The purpose of the present invention is to provide a kind of crampons with damping collision prevention function to improve making for suspension hook to reach
With safety and service life purpose, solve the easy damaged in collision field type facility of existing crane hook, generate safety accident with
And flimsy problem.
Purpose to realize the present invention, the technical solution used for：A kind of crampon with damping collision prevention function, including
Pulley shield and suspension hook, which is characterized in that the both ends of the pulley shield are equipped with frame, are equipped between the frame at both ends and are coated on pulley
Cover the buffer air bag in outside；The frame is surrounded by multiple distance-sensors, and distance-sensor is connected with controller；It is described
It is additionally provided with inflating pump and accumulator on pulley shield, is connected to by tracheae between inflating pump and buffer air bag；It the accumulator and beats
Air pump is electrically connected with the controller；Damping framework, damping framework and pulley shield has been bolted in the lower end of the pulley shield
Junction be provided with rubber damping pad；The lower part of the damping framework and the top movable of suspension hook are socketed, and the upper end of suspension hook is set
There is spring bumper cover, spring is equipped between spring bumper cover and damping framework.
Further, the frame is set as ring-shaped structure and is connected by connecting rod between frame and pulley shield.
Further, the buffer air bag is equipped with exhaust outlet able to turn on or off.
Further, the distance-sensor sets there are four and is evenly distributed on the surrounding of frame.
Further, the controller is connected with alarm, and alarm is fixed on pulley shield.
Further, the alarm includes whistle loudspeaker and warning lamp.
Further, the tracheae is flexible hose.
Further, the spring is set in the outside on suspension hook top and one end and the spring bumper cover connecting pin of spring, separately
One end is connect with damping framework.
Using the invention has the advantages that：
1. the suspension hook of the application, during practice, distance-sensor can test out suspension hook between barrier
Distance, and range information is fed back into controller, in the case of in risk distance, controller will be such that warning device sends out
Alarm song and warning lamp, dangerous to carry out warning to manipulator, at the same time controller makes to inflate pump work, by buffer air bag into
Row inflation, reduces impact force of the suspension hook in collision process, reduce and hit damage, to improve suspension hook in the process of running
Safety；
2. the present invention is effectively reduced by the rubber damping pad being arranged between damping framework and pulley shield when in use
The impulse force that pulley shield is subject in the horizontal direction, protects pulley shield well, extends the service life of pulley, reducing makes
Using high strength exploitation pulley shield and damping framework while also extended to ensure the stress of junction with cost
Its service life reduces use cost, and the setting of spring is the impact force in order to reduce suspension hook in lifting, smaller to suspension hook
Damage, extend the service life of suspension hook, the setting of spring base is to prevent spring shift position for fixed spring, and influence
Its normal use, the present invention with simple in structure, operating cost is low, service life is long, it is widely used, with the excellent of damping performance
Point.
