Abstract
The utility model relates to a through wire pipe fixing structure, in particular to a fixing structure of a through wire pipe between a slip ring and a wheel hub of a wind generating set, which belongs to the technical field of wind power generation. The technical scheme is as follows: the through wire pipe fixing structure comprises a spindle (1), a gearbox low-speed shaft (2), heat shrinkage pipes (3), foam pipes (4) and the through wire pipe (6); the spindle is in a hollow structure; the through wire pipe passes through the inside of the hollow structure of the spindle; one end of the spindle is provided with the gearbox low-speed shaft; both ends of the through wire pipe are provided with the heat shrinkage pipes; the foam pipes are arranged on both ends of the hollow structure of the spindle; the through wire pipe passes through the foam pipes; and the foam pipes fix the through wire pipe and the spindle together. The through wire pipe fixing structure has the beneficial effects that: a cable can be fully fixed with a rotary part, the harm by the winding wear is reduced, simultaneously the erosion by water is prevented, the structure is simple and the cost is low.
Description
Technical field
The utility model relates to a kind of penetration pipe fixed structure, and particularly the fixed structure of penetration pipe between wind turbine generator slip ring and wheel hub belongs to technical field of wind power generation.
Background technology
At present, mostly the cable in the wind generator unit wheel hub is that direct centre bore through gear and main shaft passes.Like this cable and metalwork between friction can damage cable sheath, the winding of cable simultaneously can reduce its useful life.
The utility model content
The purpose of the utility model provides a kind of penetration pipe fixed structure, can cable and rotating parts be fixed together, and reduces the winding of cable, and wearing and tearing in the life-span of improving cable, solve the problems referred to above that background technology exists.
The technical scheme of the utility model is: a kind of penetration pipe fixed structure, comprise main shaft, gear box slow-speed shaft, heat-shrink tube, foaming pipe and penetration pipe, and main shaft is a hollow-core construction; Penetration pipe passes in the hollow-core construction of main shaft; Main shaft one end is the gear box slow-speed shaft, and the two ends of penetration pipe are respectively equipped with heat-shrink tube, and the hollow-core construction two ends of main shaft are provided with the foaming pipe; Penetration pipe passes the foaming pipe, and the foaming pipe is fixed together penetration pipe and main shaft.
In the middle of the hollow-core construction of axle, be provided with the contoured foam pipe, penetration pipe passes the contoured foam pipe.
A penetration pipe is installed in main shaft, is supported with the contoured foam pipe in the middle of the penetration pipe, two ends are fixed together penetration pipe and main shaft through the foaming pipe, and cable enters into wheel hub through penetration pipe from slip ring.Heat-shrink tube is installed at the penetration pipe two ends, through the contraction of heat-shrink tube cable and penetration pipe is fixed.Cable and main shaft are fixed together, middle by the support of contoured foam pipe, make it to follow main shaft and rotate together, and do not twine.
The good effect of the utility model: can cable and rotating parts be completely fixed, reduce the infringement of twining wearing and tearing, can prevent the erosion of moisture simultaneously, simple in structure, with low cost.
Description of drawings
Fig. 1 is the sketch map of the utility model embodiment;
Among the figure: 1, main shaft, 2, the gear box slow-speed shaft, 3, heat-shrink tube, 4, the foaming pipe, 5, the contoured foam pipe, 6, penetration pipe.
Embodiment
Below in conjunction with accompanying drawing, the utility model is further specified through embodiment.
A kind of penetration pipe fixed structure comprises main shaft 1, gear box slow-speed shaft 2, heat-shrink tube 3, foaming pipe 4 and penetration pipe 6, and main shaft is a hollow-core construction; Penetration pipe passes in the hollow-core construction of main shaft; Main shaft one end is the gear box slow-speed shaft, and the two ends of penetration pipe are respectively equipped with heat-shrink tube, and the hollow-core construction two ends of main shaft are provided with the foaming pipe; Penetration pipe passes the foaming pipe, and the foaming pipe is fixed together penetration pipe and main shaft.In the middle of the hollow-core construction of axle, be provided with contoured foam pipe 5, penetration pipe passes the contoured foam pipe.
During assembling, at first in hollow main shaft 1, place penetration pipe 6, fill in contoured foam pipe 5 and support as the middle part.The fixing foaming pipe 4 at two ends plays a part fixing and support simultaneously then.After threading is accomplished, the suit heat-shrink tube at the penetration pipe two ends, the contraction through heat-shrink tube is fixed together cable and penetration pipe, can prevent the entering of transportation moisture simultaneously.
Claims (2)
1. a penetration pipe fixed structure is characterized in that comprising main shaft (1), gear box slow-speed shaft (2), heat-shrink tube (3), foaming pipe (4) and penetration pipe (6), and main shaft is a hollow-core construction; Penetration pipe passes in the hollow-core construction of main shaft; Main shaft one end is the gear box slow-speed shaft, and the two ends of penetration pipe are respectively equipped with heat-shrink tube, and the hollow-core construction two ends of main shaft are provided with the foaming pipe; Penetration pipe passes the foaming pipe, and the foaming pipe is fixed together penetration pipe and main shaft.
2. a kind of penetration pipe fixed structure according to claim 1 is characterized in that in the middle of the hollow-core construction of axle, being provided with contoured foam pipe (5), and penetration pipe passes the contoured foam pipe.
