Description
Technical field
The utility model relates to a kind of grab bucket, and the utility model especially relates to a kind of twin rope grab three multiplying power duplex structures.
Background technology
On the solid bolster grabbing bucket in switching steel rope one end of tradition twin rope grab, the other end extend out to a side of deck beam and the switching Suo Xianglian of hoisting crane, while opening and closing work, is subject to force unbalance, causes grab bucket not steady.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, while providing a kind of structural safety, grab bucket to open and close stressed evenly, the held stationary that makes to grab bucket, twin rope grab three multiplying power duplex structures that the suffered resistance of hawser is little.
The technical scheme providing according to the utility model, described twin rope grab three multiplying power duplex structures, comprise deck beam and through beam, on deck beam, be hinged with strut, bottom at through beam is hinged with bucket body, the bottom of strut is hinged on the middle part, back of bucket body, in the upper surface left part of deck beam, the first cable wire guide wheel is installed, in the upper surface right part of deck beam, the second cable wire guide wheel is installed, on deck beam, be provided with the first deck beam pulley and the second deck beam pulley, on through beam, be provided with the first through beam pulley, the second through beam pulley and the 3rd through beam pulley, above deck beam, be provided with suspension bracket, the first hawser shackle is installed in the left part of suspension bracket, the second hawser shackle is installed in the right part of suspension bracket, unload to buckle by the second rig thimbler at the second hawser and be connected with hawser, hawser penetrates and enters the first through beam pulley by deck beam from the second cable wire guide wheel, walk around the first through beam pulley and enter the first deck beam pulley, walk around the first deck beam pulley and enter the second through beam pulley, walk around the second through beam pulley and enter the second deck beam pulley, walk around the second deck beam pulley and enter the 3rd through beam pulley, walk around the 3rd through beam pulley and pass the first cable wire guide wheel by deck beam, finally being connected to the second hawser by the first rig thimbler unloads and buckles.
Be fixed with elevator chain mounting ear at the upper surface of deck beam, on elevator chain mounting ear, elevator chain be installed.
Be provided with suspension bracket shackle at the middle part of suspension bracket.
The utility model is run through by same hawser, and without being connected with through beam, structure is safer.In grab bucket, opening and closing hawser can regulate two ends equal in length by shackle placed in the middle on suspension bracket automatically, plays equilibrium activity, reaches stressed consistent.Stressed even when switching, the held stationary that makes to grab bucket not to tilt.The utility model has solved that twin rope grab can not do balance block structure and grab bucket is tilted while causing work problem.Meanwhile, cable stress of the present utility model is stressed less than the three multiplying power grab buckets of common double rope, also can select little No. one in the time of hawser type selecting.

Fig. 2 is left view of the present utility model.
Fig. 3 is hawser coiling schematic diagram of the present utility model.
Detailed description of the invention
Below in conjunction with specific embodiment, the utility model is described in further detail.
These twin rope grab three multiplying power duplex structures, comprise deck beam 1 and through beam 2, on deck beam 1, be hinged with strut, bottom at through beam 2 is hinged with bucket body, the bottom of strut is hinged on the middle part, back of bucket body, in the upper surface left part of deck beam 1, the first cable wire guide wheel 3.1 is installed, in the upper surface right part of deck beam 1, the second cable wire guide wheel 3.2 is installed, on deck beam 1, be provided with the first deck beam pulley 1.1 and the second deck beam pulley 1.2, on through beam 2, be provided with the first through beam pulley 2.1, the second through beam pulley 2.2 and the 3rd through beam pulley 2.3, above deck beam 1, be provided with suspension bracket 8, the first hawser shackle 7.1 is installed in the left part of suspension bracket 8, the second hawser shackle 7.2 is installed in the right part of suspension bracket 8, in the second hawser shackle 7.2, be connected with hawser 5 by the second rig thimbler 6.2, hawser 5 penetrates and enters the first through beam pulley 2.1 by deck beam 1 from the second cable wire guide wheel 3.2, walk around the first through beam pulley 2.1 and enter the first deck beam pulley 1.1, walk around the first deck beam pulley 1.1 and enter the second through beam pulley 2.2, walk around the second through beam pulley 2.2 and enter the second deck beam pulley 1.2, walk around the second deck beam pulley 1.2 and enter the 3rd through beam pulley 2.3, walk around the 3rd through beam pulley 2.3 and pass the first cable wire guide wheel 3.1 by deck beam 1, finally be connected in the second hawser shackle 7.2 by the first rig thimbler 6.1.
Be fixed with elevator chain mounting ear 10 at the upper surface of deck beam 1, elevator chain 4 is installed on elevator chain mounting ear 10.
Be provided with suspension bracket shackle 9 at the middle part of suspension bracket 8.
The utility model is run through by same hawser 5, and without being connected with through beam 2, structure is safer.Grab bucket upper cable 5 can regulate two ends equal in length by suspension bracket shackle placed in the middle on suspension bracket 89 automatically, plays equilibrium activity, reaches stressed consistent.Stressed even when switching, the held stationary that makes to grab bucket not to tilt.Solve that twin rope grab can not do balance block structure and grab bucket is tilted while causing work problem.That simultaneously three multiplying power duplex structure steel ropes are subject to the three multiplying powers grab buckets of force rate common double rope is stressed little, also can select little No. one in the time of hawser 5 type selecting.
The utility model utilizes pulley three multiplying power features, run through the first deck beam pulley 1.1, the second deck beam pulley 1.2, the first through beam pulley 2.1, the second through beam pulley 2.2 and the 3rd through beam pulley 2.3 by a hawser 5 from entering out, finally connect two ends by a suspension bracket 8 and converge into a suspension centre and reach balance, one that reaches twin rope grab three multiplying powers opens and closes pulsation-free object.
