Description
Technical field
The present invention relates to technical field of crane equipment, in particular to a kind of safety durable type of bridge crane
Crampon.
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.
On the other hand, pulley with lifting steel cable under long-term interaction, need with lubricating oil it is lubricated with
Reduce frictional force, but during the use of crampon, it is larger that often steel cable is lubricated with difficulty, is unfavorable for hoisting hook
The regular maintenance of hook；Crampon is rigidly connected because crampon belongs to when using, and lifts by crane moment huge the rushing of generation
Power, makes suspension hook directly be subject to the impulse force of vertical direction, so goes down for a long time to be easy to damage suspension hook, make making of crampon
Seriously being affected with the life-span, increased use cost, additionally, due to weight during handling it occur frequently that swinging, making cunning
The junction of wheel cover is subject to the impulse force of horizontal direction, and is rigidly connected it is impossible to relax being subject to of horizontal direction because pulley shield belongs to
Power is so as to cause serious infringement, and then affects its service life.

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., during regular maintenance is carried out to crampon, only crampon need to be placed into suitable position, then beat
Valve opening door, the lubricating oil of fuel reserve tank will be flowed into the oil spout in the hole of profit oil jacket by petroleum pipeline, with the motion of lifting steel cable,
Lubricating oil will be gradually adhered to lift by crane on steel cable, thus realizing being lubricated between lifting steel cable and pulley, easy to operate
Fast；
3. 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.
