Description

Blower turns round the anti-wear spacer ring of cable

Technical field

The utility model relates to a kind of blowers to turn round the fixed device of cable, and especially a kind of blower turns round the anti-wear spacer ring of cable.

Background technique

Currently, blower, which turns round the fixed device similar product of cable, generallys use two kinds of structures: a kind of to be made into three cables of three-phase " product " font, is bound together with band, and three cables of three-phase are made into " product " font by another kind, is stuck with anchor ear (see figure 1).When blower turns round the work of cable system, because every group of three cable be mobile and twisting is apart from different, it will lead to group Phase mutual friction occurs between three cables, so as to cause the abrasion between cable.

Above structure is by the way of anchor ear and the fixed cable of band, and when turning round the work of cable system, cable can be with pricking Phase mutual friction occurs for band or anchor ear, so as to cause the abrasion between cable and band/anchor ear.According to the form of band, will also Generate the abrasion between cable and spacer ring.

In addition, most spacer ring design is all that vertical direction is flexibly connected at present, in turning round the cable course of work, cable is turned round It is easy to rub with tower inner part, causes to turn round cable damage.

It is the most common cable class damage problem of wind-powered electricity generation industry that blower, which turns round cable abrasion, at present, and urgent need is designed according to actual condition Novel torsion cable fixed form.

Summary of the invention

In order to solve the problems, such as that wind-powered electricity generation industry turns round cable frequent wear, the utility model provide a kind of blower turn round cable it is anti-wear every Ring turns round cable and turns round the abrasion between cable to can avoid turning round cable and spacer ring, turn round cable and band.

In order to achieve the above purposes, the technical solution adopted by the utility model is:, and a kind of blower turns round the anti-wear spacer ring of cable, including " product " word bearing, guide wheel for steel wire, bolt pair, wire rope ear, spacer ring plate, " product " word bearing described in eight is by upper and lower two The clamping limit of spacer ring plate, blending bolt group is fixed, and eight " product " word bearings are evenly distributed in upper and lower two spacer ring plates；Steel Cord directive wheel is fixedly connected on two pieces of spacer ring plate centers up and down by bolt pair；Eight wire rope ears pass through bolt pair respectively It is fixedly connected with each four fixed points on upper and lower two spacer ring plates periphery.

Further, described " product " the word bearing is made of three holes, and the side wall in hole is respectively arranged with small ball.

Further, the blower turns round connecting steel wire ropes among the guide wheel for steel wire of the anti-wear spacer ring of cable.

Further, the adjacent blower, which is turned round, is fixed on wire rope ear between the anti-wear spacer ring of cable by wirerope It links together.

The beneficial effects of the utility model are:

1) isolated " product " font structure of threephase cable, can effectively avoid the abrasion between cable.

2) design has ball between cable and spacer ring, and cable and spacer ring direct friction can effectively be avoided to damage.

3) there is a positioning/limit wirerope among spacer ring, can effectively ensure that spacer ring displacement in the horizontal direction, from And it avoids turning round the friction damage between cable and tower inner part.

Specific embodiment

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

As shown in Figures 2 to 7, the blower of the utility model turns round the anti-wear spacer ring of cable, including " product " word bearing 1, spacer ring plate 2, guide wheel for steel wire 3, wire rope ear 4, bolt pair 5.

Eight " product " word bearings 1 are clamped by upper and lower two spacer ring plates 2 and are limited, and blending bolt group 5 is fixed, eight " product " word axis 1 is held to be evenly distributed in upper and lower two spacer ring plates 2.Guide wheel for steel wire 3 by bolt pair 5 be fixedly connected on up and down two pieces every 2 center of ring flat-plate.Eight wire rope ears 4 pass through each four fixed points on bolt pair and 2 periphery of upper and lower two spacer ring plates respectively It is fixedly connected.

As shown in figure 5, " product " word bearing 1 is made of three hole 1-1, the side wall of hole 1-1 is respectively arranged with small ball 1-2.Three-phase Three cables are each passed through three hole 1-1 of " product " word bearing 1, and can limit can also prevent from directly contacting simultaneously between cable and hole Friction causes cable to wear.The anchor ear or band that transmission is replaced with " product " font bearing, while playing limit, prevent twist-stop cable Friction occurs between spacer ring to cause to wear, while bearing can prevent contact friction emergency abrasion between cable.

As shown in figure 8, blower turns round the intermediate connecting steel wire ropes 6 of guide wheel for steel wire 3 of the anti-wear spacer ring of cable, it is anti-that blower turns round cable Displacement of the spacer ring in horizontal both direction is worn by 6 restriction of guide wheel for steel wire 3 and wirerope；To avoid turn round cable with Tower inner part collides with.

Such as Fig. 9, shown in 10, adjacent blower, which is turned round, to be fixed on wire rope ear between the anti-wear spacer ring of cable by wirerope And it links together.
