Abstract
The utility model provides an arrangement structure applicable to a hydraulic pipeline and an electric circuit in a stretching structure. The arrangement structure is characterized by comprising a plurality of reeling devices wound with pipelines, which are sequentially arranged on a stretching unit of one or more than one stretching structure; and the pipelines on each two adjacent reeling devices are connected through a pipeline connector. According to the arrangement structure provided by the utility model, the pipeline at one end of the stretching structure is connected with the other end of the stretching structure through the pipeline wound with each reel, a connection pipeline and the pipeline connector, so that the size of each reel and the suspension length of the pipeline at a drawn-out state can be reduced. Therefore, the hang-down distance of the pipelines and the interference possibility of the pipelines and the structure can be reduced.
Description
Technical field
The utility model relates to a kind of particularly arrangement structure of hydraulic tubing and electric wiring in the stretching structure on hoisting crane body of the tower and the crane arm of engineering truck that is applicable to.
Background technology
At present, the arrangement of the hydraulic tubing in various telescopic structure and electric wiring (hereinafter to be referred as " pipeline ") is of all kinds, as utilizes structure itself, drag chain or reel etc. as the layout carrier of pipeline.But all kinds of corrupt practices creep in practice for these method for arranging, as utilize the structure that structure itself and towing chain device arrange may be very complicated and whole device is very heavy, owing to utilizing reel uncomplicated and lighter as the carrier arrangement form, reel has obtained using more and more widely in stretching structure.But in the at present telescopic structure, particularly hoisting crane body of the tower and the crane arm of multi-stage telescopic, the overwhelming majority only utilizes a reel that is arranged in the telescoping mechanism root that pipeline is delivered to the telescoping mechanism head, at least need on the reel around upper long pipeline the same as collapsing length, so, the collapsing length more pipeline of the required coiling of long paper dish is just longer, cause and in multi-stage expansion mechanism, use the required spool structure size of reel larger, and the unsettled length of pipeline is also longer, make its sagging distance larger, such reel is arranged very inconvenient; And pipeline is longer, and the possibility of itself and constructive interference is larger.
Summary of the invention
The purpose of this utility model provides a kind of arrangement structure that is applicable to hydraulic tubing and electric wiring in the stretching structure just for existing weak point in the above-mentioned prior art.
The purpose of this utility model can realize by following technique measures:
Of the present utility modelly be applicable to the arrangement structure of hydraulic tubing and electric wiring in the stretching structure and comprise that on the telescopic unit that is arranged in successively every joint or a few joint stretching structures several are wound with the reeling device of pipeline, and the pipeline on the per two adjacent reeling devices connects by pipe joint.
The beneficial effects of the utility model are as follows:
The utility model by each reel around pipeline and associated line and pipe joint the pipeline of stretching structure one end is connected to the stretching structure other end, reduce like this size of each reel and pipeline and be in unsettled length when being drawn out state, thus the interference possibility that has reduced the sagging distance of pipeline and reduced pipeline and structure.
Description of drawings
Fig. 1 is annexation schematic diagram of the present utility model.
The specific embodiment
The utility model is further described below with reference to embodiment (accompanying drawing):
As shown in Figure 1, of the present utility modelly be applicable to the arrangement structure of hydraulic tubing and electric wiring in the stretching structure and comprise that on the telescopic unit that is arranged in successively every joint stretching structure several are wound with pipeline 1,4 reeling device 3, and the pipeline on the per two adjacent reeling devices connects by pipe joint 2.Described pipeline 1 is hydraulic pipe or electric wiring; Described pipe joint 2 is hydraulic fitting or electric wiring joint.
More specifically: described telescopic unit is by n(n 〉=3) individual telescopic unit forms (5 shown in Fig. 1,6,7,8 be respectively first, second, third, this telescopic unit of n), arrange a reeling device (be fixed on corresponding telescopic unit or can along the rail moving that is fixed on telescopic unit) at every joint (perhaps a few joints) telescopic unit, the pipeline on the adjacent reel connects by pipe joint.When telescoping mechanism stretches out, pipeline on the reel can be drawn out along with telescopic unit, and reel remains that certain pulling force is subject to and the power that is drawn out opposite direction pipeline, and when pipeline was drawn out, its extended length can both be mated with the length of telescopic unit elongation constantly.When telescoping mechanism is retracted, pipeline on the reel can be wound on the reel along with telescopic unit is retracted by reel, and reel remains that certain pulling force makes pipeline be subject to the power identical with being pulled direction, when pipeline was pulled like this, it can both be mated with the distance of telescopic unit retraction constantly by the length that reel is regained.
Claims (1)
1. arrangement structure that is applicable to hydraulic tubing and electric wiring in the stretching structure, it is characterized in that: described arrangement structure comprises that on the telescopic unit that is arranged in successively every joint or a few joint stretching structures several are wound with the reeling device of pipeline, and the pipeline on the per two adjacent reeling devices connects by pipe joint.
