Summary of the invention
The purpose of the utility model is, a kind of grab bucket simple in structure, that can horizontally rotate reliably is provided.
In order to achieve the above object, the utility model is achieved in that
A kind of grab bucket that horizontally rotates, it comprises the saddle body, be located at saddle body bottom bucket body, be located at the suspension apparatus at saddle body top; It also comprises whirligig; Said whirligig is located between saddle body and the suspension apparatus; The pivoting support that this device comprises that framework, suspension bracket, outer ring and frame roof are affixed, inner ring and suspension bracket are affixed, be located at driving oil cylinder in the framework, be located in the framework and the torsion pass frame affixed with driving oil cylinder, the top of said torsion pass frame is fixed in the frame roof; Suspension apparatus is connected with suspension bracket on the whirligig, can not horizontally rotate between the two.
The described grab bucket that horizontally rotates, whirligig also comprises oil-sealing sleeve and mandrel; Mandrel is fixed in suspension bracket central authorities and after passing the inner ring of pivoting support, is located in the torsion pass frame, and oil-sealing sleeve is placed on the mandrel.
The described grab bucket that horizontally rotates, parallel symmetry has at least two chutes that run through on the torsion pass frame, and the length of said chute is greater than 50% of the horizontal girth of torsion pass frame.
The described grab bucket that horizontally rotates, the inside of mandrel and oil-sealing sleeve are provided with at least two oil pipe pipelines, and the end of this pipeline passes the chute on the torsion pass frame.
The described grab bucket that horizontally rotates, oil pipe pipe end can horizontally rotate 0 ° ~ 300 ° in the chute of torsion pass frame.
The described grab bucket that horizontally rotates, the pivoting support outside on the whirligig is provided with positioning sleeve.
The described grab bucket that horizontally rotates, the oscillating oil cylinder on the said whirligig are oscillating oil cylinder.
The described grab bucket that horizontally rotates, suspension apparatus is connected with suspension bracket on the whirligig, and connection does not between the two have the degree of freedom of horizontally rotating.
The utility model adopts above-mentioned design, and its advantage is that promoting framework and final promotion saddle body and grab bucket by the firm torsion pass frame of single spiral oscillating oil cylinder fit structure horizontally rotates; So, simple in structure, transmission is direct, and power loss is few, thereby has overcome the defective of existing rotation grab bucket.

Fig. 3 is the axonometric drawing of torsion pass frame in the utility model whirligig.
The specific embodiment
Below further specify the utility model through specific embodiment.
As shown in Figure 1; A kind of grab bucket that horizontally rotates, it comprises saddle body 1, be located at saddle body 1 bottom bucket body 2, be located at the suspension apparatus 4 at saddle body 1 top; It also comprises whirligig 3; Said whirligig 3 is located between saddle body 1 and the suspension apparatus 4; The pivoting support 306 that this device comprises that framework 304, suspension bracket 307, outer ring and framework 304 tops are affixed, inner ring and suspension bracket 307 are affixed, be located at driving oil cylinder 301 in the framework 304, be located in the framework 304 and the torsion pass frame 309 affixed with driving oil cylinder 301, the top of said torsion pass frame 309 is fixed in framework 304 tops; Suspension apparatus 4 is connected with suspension bracket 307 on the whirligig 3, can not horizontally rotate between the two.
As shown in Figure 2, the described grab bucket that horizontally rotates, whirligig 3 also comprises oil-sealing sleeve 303 and mandrel 302; Mandrel 302 is fixed in suspension bracket 307 central authorities and behind the inner ring that passes pivoting support 306, is located in the torsion pass frame 309, and oil-sealing sleeve 303 is placed on the mandrel 302.
As shown in Figure 3, the described grab bucket that horizontally rotates, parallel symmetry has at least two chutes that run through on the torsion pass frame 309, and the length of said chute is greater than 50% of the horizontal girth of torsion pass frame.
