Description
Technical field
This utility model relates to a kind of steady bucket device of grabbing bucket, specifically the steady bucket device of a kind of multi-functional crawler crane grab bucket.
Background technology
The fields such as multi-functional crawler crane is grabbed bucket at harbour, forest farm, shipping work are widely used. Grab bucket is connected with main frame by steel wire rope. During grab bucket operation, owing to complete machine revolution is very fast, work range changes greatly, the grab bucket sling is rocked relatively big, makes staff can not efficiently control grab bucket, and serious have impact on work efficiency, and there is certain potential safety hazard.
Multi-functional crawler crane of the prior art steady bucket device of grabbing bucket is by the rail welding that surely struggles against on arm, then is assemblied on guide rail by movable slider, steel wire rope is walked around dynamic fixed pulley and is individually fixed on grab bucket and movable slider, finally play steady bucket effect. There is following defect in above-mentioned prior art:
1) by rail welding on arm, it is not easy to when rail damage safeguard, and is not easy to the extension of other functions of multifunctional crane;
2) movable slider being installed on the side of arm, will cause arm unbalance stress, movable slider slides and easily occurs that clamping stagnation and pulley too much cause dismounting inconvenience.
Utility model content
For above-mentioned prior art Problems existing, this utility model provides a kind of multi-functional crawler crane steady bucket device of grab bucket, a suitable adjustable stability force can be provided to grab bucket, it is to avoid grab bucket significantly swings under the effect of inertia force, improve work efficiency. Meanwhile, this device meets the requirement of crane Multi-function extension and is easy to dismounting and operation.
To achieve these goals, this steady bucket device includes the steady bucket device main body being fixed on principal arm coxopodite arm by fixture, guide rail and fixed pulley;
Described guide rail is provided with gravity dolly;
Described steady bucket device main body is walked around the assembly pulley on described gravity dolly and described fixed pulley by steel wire rope and is connected with grab bucket.
Further, described guide rail is welded by U-type groove steel;
Described gravity dolly contacts with guide rail bidirectional rolling with lateral roller by being installed on the roller of its both sides.
Further, described gravity dolly is provided with adjustable balancing weight.
Further, the two ends of described guide rail are provided with cushion pad.
Compared with prior art, this multi-functional crawler crane steady bucket device of grab bucket has the advantages that
1) this steady bucket device adopts bilateral track, compact conformation, and stability is strong, and track realizes rolling friction with gravity dolly by bearing, slides without clamping stagnation;
2) this steady bucket device adopts assembled with principal arm, it is simple to dismounting, meets the demand of multifunctional crane, embodies the convenience of this steady bucket device;
3) pulling force that grab bucket is provided by this steady bucket device is nonlinear, changes with work range and the hoisting depth change of crane, and steady bucket action effect is notable, it is simple to operation;
4) in this steady bucket device the weight of gravity dolly can according to balancing weight number regulate, the multiplying power of wirerope-winding also has multiple choices, this makes it possible to the difference according to capturing material and chooses the stability force that suitable weight provides suitable.

Detailed description of the invention
Below in conjunction with accompanying drawing, this utility model is described further.
As depicted in figs. 1 and 2, this steady bucket device includes the steady bucket device main body 20 being fixed on principal arm coxopodite arm 24 by fixture 22, guide rail 25 and fixed pulley 27;
Described guide rail 25 is provided with gravity dolly 23;
Described steady bucket device main body 20 is walked around the assembly pulley 34 on described gravity dolly 23 and described fixed pulley 27 by steel wire rope 26 and is connected with grab bucket 10.
The operation principle of this multi-functional crawler crane steady bucket device of grab bucket is as follows:
As depicted in figs. 1 and 2, steady bucket device main body 20 is assemblied on principal arm coxopodite arm 24 by fixture 22 by this steady bucket device when grabbing bucket operation, and gravity dolly 23 can be slidably in guide rail 25. In the duty of Fig. 2, steel wire rope 26 is produced an active force by gravity dolly 23 under gravity, this active force acts in grab bucket 10 eventually through steel wire rope 26, so when grabbing bucket 10 operation revolutions, luffing, shaking amplitude and the frequency of grab bucket 10 can be limited significantly, play the effect of steady bucket. When gravity dolly 23 to grab bucket 10 active force excessive time, likely occur that grab bucket 10 deviates vertical position too close to jib, when the jib work elevation angle increases suddenly, grab bucket 10 likely hits jib, as shown in Figure 4, at this moment can pass through to reduce the quantity of the balancing weight 31 on gravity dolly 23, reduce the gravity dolly 23 active force to grab bucket 10. Otherwise, when steady bucket effect is inconspicuous, it is possible to increase the quantity of balancing weight 31 on gravity dolly 23.
This steady bucket device is when operation, and the length of steel wire rope 26 can transfer according to grab bucket 10, the distance, work range and the work multiplying power that promote are determined. During other operations beyond grabbing bucket of crane, it is possible to steady bucket device main body 20 entirety is pulled down, other hoisting functions are not affected.
Further, described guide rail 25 is welded by U-type groove steel; Described gravity dolly 23 contacts with guide rail 25 bidirectional rolling with lateral roller 33 by being installed on the roller 32 of its both sides.It is greatly reduced frictional resistance during rolling.
Further, described gravity dolly 23 is provided with adjustable balancing weight 31. The quantity of balancing weight 31 on gravity dolly 23 can be determined according to the difference of grab bucket 10 crawl material when operation.
Further, the two ends of described guide rail 25 are provided with cushion pad 21. Can effectively reduce the gravity dolly 23 impulsive force when operation.
In sum, grab bucket can be provided a suitable adjustable stability force by this multi-functional crawler crane steady bucket device of grab bucket, it is to avoid grab bucket significantly swings under the effect of inertia force, improves work efficiency. Meanwhile, this device meets the requirement of crane Multi-function extension and is easy to dismounting and operation.
