Description

Blower turns round cable limiting device

Technical field

The utility model relates to a kind of wind-driven generator, the electric wiring of especially a kind of wind-driven generator turns round cable limit dress It sets.

Background technique

Cable system is turned round, as shown in figures 1 and 2, usually by torsion cable 1, torsion cable protection device 2, torsion cable limiting device 3, overboard gulf 4 Composition.Turning round cable 1 is usually one group of three-phase, is to connect the changeover portion for fixing cable in cabin inner cable and tower, it is inclined to solve cabin During boat, cable torsion problem；Cable protection device 2 is turned round, cable is turned round for protecting, to prevent colliding with other component in tower Cause cable bad；Browse limiting device 3, for limits turn round cable bottom movement, usually limit maximum rotation angle to prevent Twist-stop cable crosses torsion and causes cable damage；Overboard gulf 4 is to turn round to be reserved in cable come to supplement the increase turned round and needed in cable twist process Length torsion cable section；

Similar product is generallyd use such as flowering structure at present:

Above structure is made of four parts: 5: entire limiting device support frame: is supported in short transverse；6: turn round cable anchor ear: For fixing one group of threephase cable；7: limit outer ring: it is integral with support frame welding, it can be rotated around inner ring；8: limit Inner ring: being fixed in tower, for supporting outer ring to rotate and controlling maximum rotation angle.

The defect of such product is: can only provide the rotation for turning round cable bottom certain angle, only focus on excessive distortion and made At influence.And turning round between cable and anchor ear is that fixed clamping stagnation connects, therefore not can guarantee and turn round the movement of cable in vertical direction. Then, cable is turned round in action process, torsion cable is done around rotary shaft to be rotated and becomes helical form, and length is greater than initial length, Therefore the displacement also needed on a vertical direction in cable movement is turned round.And this class formation hood type structure, then limit torsion cable Vertical displacement amount between it, causes to wear over time.

Summary of the invention

In order to solve the technical issues of wind-powered electricity generation industry turns round cable frequent wear, the utility model provides a kind of torsion cable bottom limit Device, so as to avoid turning round cable excessive distortion and turning round the abrasion between cable and limiting device.

In order to achieve the above purposes, the technical solution adopted by the utility model is:, and a kind of blower turns round cable limiting device, including branch Main body, limition orientation rope, guide limiting stopper, spacer ring, central guide rope, fixed arm are supportted, the supportive body is vertically connected with method Four limition orientation ropes are fixedly connected between blue end face, multiple guide limiting stoppers pass through idler wheel and four limition orientation ropes respectively It is slidably connected, spacer ring is fixedly connected with above guide limiting stopper, central guide rope passes through multiple guide limiting stoppers and spacer ring, support master Body top is fixedly connected with fixed arm.

Further, the fixed arm is fixed on tower inside by the connecting flange of end.

Further, the supportive body is fixedly connected with fixed arm by bolt group.

Further, the limition orientation rope upper and lower ends pass through nut respectively and connect with supportive body, and by adjusting spiral shell Mother tightens guide rope.

Further, fixation is bolted between the spacer ring and guide limiting stopper, torsion cable, institute are installed in the spacer ring It states and is connected between spacer ring by wirerope.

The beneficial effects of the utility model are:

1) torsion that cable is turned round in bottom is limited using guide rope；

2) limiting device can be slided along guide rope, so that length caused by compensating torsion cable during the work time changes；

3) cable bottom limiting device is turned round to connect with the newly-designed torsion cable spacer ring of the distant view energy, in turning round cable action process, energy Enough guarantee limiting device and turn round to wear between cable.

Specific embodiment

The utility model is described in further detail with embodiment with reference to the accompanying drawing.

As shown in Figures 3 to 12, the blower of the utility model turns round cable limiting device, including supportive body 11, limition orientation Rope 12, guide limiting stopper 13, spacer ring 14, central guide rope 15, fixed arm 16 etc..

Being vertically connected between end face of flange for supportive body 11 is fixedly connected with four limition orientation ropes 12, multiple guiding limits Position block 13 is slidably connected by idler wheel with four limition orientation ropes 12 respectively, and guide limiting stopper 13 is fixedly connected with spacer ring 14 above, Central guide rope 15 passes through multiple guide limiting stoppers 13 and spacer ring 14(is shown in Figure 13), 11 top of supportive body is fixedly connected with fixed arm 16。

As shown in figure 5, fixed arm 16 is fixed on tower inside by the connecting flange 16-1 of end.

As shown in fig. 6,11 top of supportive body is equipped with fixed bolt hole 11-1.

As shown in fig. 7, supportive body 11 is connect with fixed arm 16 by bolt group 20.

Such as Fig. 8, shown in 9,12 up/down both ends of limition orientation rope are connect by nut 21 with supportive body 11, and adjust spiral shell Mother 21 tightens limition orientation rope 12.

As shown in Figure 10, guide limiting stopper 13 can be slided by idler wheel on four limition orientation ropes 12, but because being limited Position guide rope 12 is in tensioned state, and guide limiting stopper 13, which can not reverse, to be slided up and down.

It such as Figure 11, shown in 12, is bolted between spacer ring 12 and guide limiting stopper 13, to realize limition orientation rope 12, by guide limiting stopper 13, limit the movement of spacer ring 14, are installed with torsion cable in spacer ring 14, turn round cable in the torsion of bottom to limit Turn.Spacer ring 12 is by the spacer ring 12 above steel wire hang and its, so that the position before ensure that spacer ring 12 and spacer ring 12 is closed System.

The utility model structure is simple, and cost is relatively low for all parts, and the limiting component of core is all common structural steel Or rubber material composition；Functionally advantage: it is limited well turns round torsion of the cable at this position and simultaneously and provides enough Vertical direction is displaced to make up the variation of cable length in twist process, and whole process cable will not cause additional because of torsion Load.Existing most torsion cable structure is designed to limit its maximum twist angle to prevent cable from being caused by transition torsion The excessive damage of stress, but in actual use, it turns round cable and still has the case where causing stretching because of torsion, and is opposite with spacer ring generation Sliding causes to wear.
