Abstract
The utility model discloses an external drag chain device for a telescopic boom, which comprises a boom holder, a base boom, a telescopic boom and a hydraulic pipeline. A drag chain guide groove is arranged on the base boom, and a drag chain is mounted on the drag chain guide groove; a telescopic boom support is mounted at the front end of the telescopic boom; the front end of the drag chain is fixedly connected with the front end of the drag chain guide groove; the front end of the drag chain is laid along the direction of the drag chain guide groove, and after reaching the rear portion of the base boom, the front end of the drag chain is bent upwards to advance to be fixedly connected with the telescopic boom support; and the hydraulic pipeline is laid in the drag chain. The external drag chain device for the telescopic boom is suitable for short crane booms, the direction of the drag chain is guaranteed not to deflect through the drag chain guide groove, and the hydraulic pipeline is arranged in the drag chain device so that the hydraulic pipeline is well fixed and protected. The drag chain is made of acrylonitrile butadiene styrene (ABS) engineering plastics, is light and free from rust, and has an attractive appearance and a long service life in outdoor environment.
Description
Technical field
The utility model belongs to the crane technical field, relates in particular to a kind of external drag chain device of telescoping boom of crane.
Background technology
The telescopic arm of the car hosit that generally uses now, its keystone configuration are that telescoping boom promotes to slide at the inner telescopic oil cylinder that relies on of basic arm, because the fore and aft motion of telescoping boom causes a large amount of pipelines on arm, to install.
Give the telescopic hoist boom installation pipeline at present, generally adopt circular wound form Bobbin structure, the electric wiring that diameter is less is laid immediately on the jib of arm, and when hoisting arm expansion, drum will pull out or twine back along with circuit.If desired that diameter is bigger hydraulic tubing is laid to arm head from arm, does not have ideal method at present.
The utility model content
The purpose of the utility model is to provide a kind of external drag chain device that hydraulic tubing is installed of being convenient to.
For realizing above-mentioned purpose, the technical scheme that the utility model is taked is:
A kind of external drag chain device of telescoping boom comprises arm bearing, basic arm, telescoping boom and hydraulic tubing, and the top of said basic arm is provided with the drag chain guide groove, and said drag chain guide groove is provided with drag chain; The front end of said telescoping boom is provided with the telescoping boom support; Said drag chain front end is captiveed joint with the front end of said drag chain guide groove; The said drag chain guide groove of the front end edge of said drag chain is laid, and forward, captives joint with said telescoping boom support to the rear portion K/UP of said basic arm; Said hydraulic tubing is laid on the inside of said drag chain.
The material of said drag chain is the ABS engineering plastics.
The external drag chain device of the telescoping boom that use the utility model provides; Be applicable to the suspension arm of crane that brachium is short; The direction that the drag chain guide groove can be guaranteed drag chain is deflection not, is laid on drag chain device in-to-in hydraulic tubing, hydraulic tubing is well fixed and protects.The drag chain material adopts the ABS engineering plastics, and is in light weight, non-corrosive, appearance looks elegant, long service life in the environment in the open.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Fig. 2 is the working state schematic representation of the utility model.
Among the figure, 1-arm bearing, 2-basic arm, 3-telescoping boom, 4-drag chain, 5-hydraulic tubing, 6-drag chain guide groove, 7-telescoping boom support, 8-drag chain front end.
The specific embodiment
Below in conjunction with specific embodiment and accompanying drawing thereof the utility model is described further.
As shown in Figure 1, comprise arm bearing 1, basic arm 2, telescoping boom 3 and hydraulic tubing 5, the top of basic arm 2 is connected with drag chain guide groove 6 with bolt, is equipped with drag chain 4 on the drag chain guide groove 6.The front end of telescoping boom 3 is welded with telescoping boom support 7.Drag chain front end 8 is connected with bolt with the front end of drag chain guide groove 6, and drag chain 4 is laid along drag chain guide groove 6 backward, to the rear portion K/UP of basic arm 2, sets up forward according to its deadweight, is connected with telescoping boom support 7 usefulness bolt.Hydraulic tubing 5 is laid on the inside of drag chain 4; The inside of drag chain 4 is trench structure; Hydraulic tubing 6 penetrates laying in the inside of drag chain 4; Lay to the head of telescoping boom 3 by basic arm 2 extensions, so just well solved the installation question of hydraulic tubing, hydraulic tubing 5 can be moved with the motions such as bending of drag chain 4.
As shown in Figure 2, this is the flexible later state of arm 3 elongations of transferring, and the rear end of drag chain 4 is driven by telescoping boom 3, and drag chain 4 moves along drag chain guide groove 6; Hydraulic tubing 5 moves with drag chain 4, has solved the installation question of hydraulic tubing on the telescoping boom.
Above-described only is the preferred embodiment of the utility model, does not limit to the utility model.Should be understood that for the person of ordinary skill of the art, under the teachings that the utility model provided, can also make other equivalent modifications and improvement, all can realize the purpose of the utility model, all should be regarded as the protection domain of the utility model.
