Description
Technical field
The present invention relates to technical field of crane equipment, in particular to a kind of hoisting hook with damping collision prevention function
Hook.
Background technology
The cleaning of bridge crane track is usually using crampon, goods to be handled to be lifted at present
And transfer, the heavier mass of crampon, crampon includes pulley shield, the pulley being located on pulley shield and suspension hook, lifting
Machine realizes the lifting 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 of lifting steel cable is again larger, thus easily cause the collision of crampon and field apparatus,
Or the collision with field worker, easily occurs security incident and the situation of damage on-site facility to occur.
Crampon is rigidly connected because crampon belongs to when using, and lifts by crane the huge impulse force of moment generation, makes
Suspension hook is directly subject to the impulse force of vertical direction, so goes down for a long time to be easy to damage suspension hook, makes the use longevity of crampon
Life is seriously affected, and increased use cost, additionally, due to weight during handling it occur frequently that swinging, makes pulley shield
Junction be subject to the impulse force of horizontal direction, and be rigidly connected it is impossible to relax the stress of horizontal direction because pulley shield belongs to, make
It causes serious infringement, and then affects its service life.
Content of the invention
It is an object of the invention to provide a kind of crampon with damping collision prevention function improves making of suspension hook to reach
With safety and service life purpose, solve existing crane hook easy damaged in collision field type facility, produce security incident with
And flimsy problem.
For realizing the object of the invention, the technical scheme of employing is：A kind of crampon with damping collision prevention function, including
Pulley shield and suspension hook, it is characterised in that the two ends of described pulley shield are provided with framework, are provided between the framework at two ends and are coated on pulley
The buffer air bag in cover outside；Described framework be formed around multiple distance-sensor, distance-sensor is connected with controller；Described
Inflating pump and accumulator are additionally provided with pulley shield, are connected by trachea between inflating pump and buffer air bag；Described accumulator and beating
Air pump is all electrically connected with the controller；The lower end of described pulley shield has been bolted damping framework, damping framework and pulley shield
Junction be provided with rubber damping pad；The bottom of described damping framework is socketed with the top movable of suspension hook, and the upper end of suspension hook sets
There is spring bumper cover, between spring bumper cover and damping framework, be provided with spring.
Further, described framework is set to ring-shaped structure and is connected by connecting rod between framework and pulley shield.
Further, described buffer air bag is provided with air vent able to turn on or off.
Further, described distance-sensor is provided with four and is evenly distributed on the surrounding of framework.
Further, described controller is connected with alarm, and alarm is fixed on pulley shield.
Further, described alarm includes blow a whistle loudspeaker and warning lamp.
Further, described trachea is flexible hose.
Further, described spring is set in outside and one end of spring and the spring bumper cover connection end on suspension hook top, separately
One end is connected with damping framework.
Using the invention has the advantages that：
1. the suspension hook of the application is during practice, distance-sensor can test out suspension hook between barrier away from
From, and range information is fed back to controller, in the case of being in risk distance, controller will make alarm device send police
Report sound and warning lamp, dangerous so that manipulator is carried out with warning, meanwhile controller makes to inflate pump work, and buffer air bag is carried out
Inflation, reduces impact force in collision process for the suspension hook, reduces and clashes into infringement, thus improve peace in running for the suspension hook
Quan Xing；
2. the present invention effectively reduces pulley when using by the rubber damping pad of setting between damping framework and pulley shield
Cover the impulse force being subject in the horizontal direction, protect pulley shield well, extend the service life of pulley, reduce and use into
This, be to ensure that the stress of junction, also extend it makes simultaneously using high strength exploitation pulley shield and damping framework
With the life-span, reduce use cost, being disposed to of spring reduces the impulsive force in lifting for the suspension hook, the less damage to suspension hook
Evil, extends the service life of suspension hook, spring base be disposed to fixing spring, prevent spring shift position, and just affect it
Often use, the present invention has the advantages that structure is simple, operating cost is low, long service life, of many uses, there is damping performance.
