The bucket stabilizing device body (20) is connected with a grab bucket (10) in a manner that a steel wire rope (26) winds around a pulley set (34) on the gravity trolley (23) and the fixed pulley (27). According to the grab bucket stabilizing device for the multifunctional crawler crane, the proper adjustable stabilizing force can be provided for the grab bucket, it is avoided that the grab bucket swings within a large range under the action of the inertia force, and working efficiency is improved; and meanwhile, the grab bucket stabilizing device meets the requirement for multifunctional expansion of the crane and is convenient to disassemble, assemble and operate.
Description
Technical field
The present invention relates to the steady bucket device of a kind of grab 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 rope.During grab bucket operation, because complete machine revolution is very fast, work range changes greatly, the grab bucket of slinging is rocked comparatively large, and make staff effectively can not control grab bucket, serious have impact on work efficiency, and there is certain potential safety hazard.
The steady bucket device of multi-functional crawler crane grab bucket of the prior art is by the rail welding that surely struggles against on arm, then is assemblied on guide rail by movable slider, steel 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, be not easy to when rail damage safeguard, and be not easy to the expansion of other functions of multifunctional crane;
2) movable slider is installed on the side of arm, will causes arm unbalance stress, movable slider slip easily occurs clamping stagnation and pulley too much causes dismounting inconvenience.
Summary of the invention
For above-mentioned prior art Problems existing, the invention provides the steady bucket device of a kind of multi-functional crawler crane grab bucket, adjustable stability force that one suitable can be provided grabbing bucket, avoid grab bucket significantly to swing under the effect of force of inertia, increasing work efficiency.Meanwhile, this device meets the requirement of hoisting crane Multi-function extension and is convenient to dismounting and operation.
To achieve these goals, this steady bucket device comprises the steady bucket device main body be fixed on by connecting element on principal arm coxopodite arm, guide rail and fixed pulley;
Described guide rail is provided with gravity dolly;
Described steady bucket device main body walks around assembly pulley on described gravity dolly by steel rope and described fixed pulley is connected with grab bucket.
Further, described guide rail is welded by U-type groove steel;
Described gravity dolly is contacted with guide rail bidirectional rolling with side direction roller by the roller being installed on its both sides.
Further, described gravity dolly is provided with adjustable clump weight.
Further, the two ends of described guide rail are provided with cushion rubber.
Compared with prior art, the steady bucket device of this multi-functional crawler crane grab bucket has following beneficial effect:
1) this steady bucket device adopts bilateral track, compact conformation, and stability is strong, and track and gravity dolly realize friction of rolling by bearing, slides without clamping stagnation;
2) this steady bucket device and principal arm adopt build-up type, are convenient to dismounting, meet the demand of multifunctional crane, embody the convenience of this steady bucket device;
3) this steady bucket device is nonlinear to pulling force provided of grabbing bucket, and change with the work range of hoisting crane and hoisting depth change, steady bucket action effect is remarkable, convenient operation;
4) in this steady bucket device gravity dolly weight can according to clump weight number regulate, the multiplying power of wirerope-winding also has multiple choices, this makes it possible to choose according to the difference capturing material the stability force that suitable weight provides suitable.

Detailed description of the invention
Below in conjunction with accompanying drawing, the present invention will be further described.
As depicted in figs. 1 and 2, this steady bucket device comprises the steady bucket device main body 20 be fixed on by connecting element 22 on principal arm coxopodite arm 24, guide rail 25 and fixed pulley 27;
Described guide rail 25 is provided with gravity dolly 23;
Described steady bucket device main body 20 walks around assembly pulley 34 on described gravity dolly 23 by steel rope 26 and described fixed pulley 27 is connected with grab bucket 10.
The principle of work of the steady bucket device of this multi-functional crawler crane 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 connecting element 22 when grabbing bucket operation by this steady bucket device, and gravity dolly 23 can be free to slide in guide rail 25.In the mode of operation of Fig. 2, gravity dolly 23 produces an application force to steel rope 26 under gravity, this application force acts in grab bucket 10 eventually through steel rope 26, like this when grab bucket 10 operation revolution, luffing, shaking amplitude and the frequency of grab bucket 10 can be limited significantly, play the effect of steady bucket.When the application force of gravity dolly 23 to grab bucket 10 is excessive, likely occur that grab bucket 10 too departs from vertical position near jib, when the jib work elevation angle increases suddenly, grab bucket 10 likely hits jib, as shown in Figure 4, at this moment by reducing the quantity of the clump weight 31 on gravity dolly 23, the application force of gravity dolly 23 to grab bucket 10 can be reduced.Otherwise, when steady bucket effect is not obvious, the quantity of clump weight 31 on gravity dolly 23 can be increased.
This steady bucket device is when operation, and the length of steel rope 26 can be transferred 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 hoisting crane, steady bucket device main body 20 entirety can be pulled down, other hoisting functions are not affected.
Further, described guide rail 25 is welded by U-type groove steel; Described gravity dolly 23 is contacted with guide rail 25 bidirectional rolling with side direction roller 33 by the roller 32 being installed on its both sides.Reduce friction drag during rolling greatly.
Further, described gravity dolly 23 is provided with adjustable clump weight 31.The difference that can capture material according to grab bucket 10 when operation determines the quantity of clump weight 31 on gravity dolly 23.
Further, the two ends of described guide rail 25 are provided with cushion rubber 21.Effectively can reduce the impulsive force of gravity dolly 23 when operation.
In sum, the steady bucket device of this multi-functional crawler crane grab bucket can provide a suitable adjustable stability force to grabbing bucket, avoid grab bucket significantly to swing under the effect of force of inertia, increase work efficiency.Meanwhile, this device meets the requirement of hoisting crane Multi-function extension and is convenient to dismounting and operation.
