Description

Dead-weight cable turns round correction roller rack again

Technical field

The utility model belongs to cable maintenance field, turns round correction roller rack again more particularly, to a kind of dead-weight cable.

Background technology

The power supply of container terminal loading and unloading gantry crane is transmitted by the cable being laid in open type cable trench, cable with The terminal that gantry crane twines inside cable device is attached.It is rotated with the movement of gantry crane due to twining cable device, inside the cable in strand Cable is gradually set to generate torsion under the action of stress.

The torsion of cable can cause the torsional deflection of cable outer layer insulating layer, the excessive torsion of cable that can cause cable The internal stress of outer insulation increases, to cause the shortening of cable service life.

The influence brought to cable service life is excessively reversed to mitigate cable, the torsion degree of television cable is electricity in time Cable is turned round be necessary again.

The multiple torsion operation of cable is that cable is needed to be carried out outside slot from taking-up in cable trough.Usual cable takes from cable trough It after going out, lies on harbour face, carries out multiple torsion operation by being no less than 10 people, there is resistance torque when due to multiple torsion and operation is not square Just, therefore turning round operation again, time-consuming.

Invention content

In view of this, the utility model is directed to a kind of dead-weight cable turns round correction roller rack again, to solve Carry out cable carry out it is multiple turn round corrective operations during, excessive manpower carry out it is multiple turn round operation, exist when due to multiple torsion resist torque and It is inconvenient for operation, and it is multiple turn round operation time-consuming and for the multiple torsion of cable correction it is ineffective the problems such as.

In order to achieve the above objectives, the technical solution of the utility model is realized in：

Dead-weight cable turns round correction roller rack, including collet, support element and multiple roller bearings again；

The support element is arranged on the collet, and multiple roller bearings are arranged on the support element, the roller bearing It is one-directional rotation connection with the support element, one or more cable widths can be accommodated by being equipped between the adjacent roller bearing Space.

Further, there are two the roller bearing is set, at left and right sides of each roller bearing roller carrier shaft described in roller carrier shaft is equipped with to pass through The unilateral bearing connection left and right sides holder, two idler wheel height are identical.

Further, two roller bearings are only capable of being one-directionally rotated.

Further, the support element includes two holders, and two holders are symmetricly set on described collet or so two Side is equipped with the U-lag that can place cable on each holder, the twice stud being equipped on each holder.

Further, the holder and the collet are welding.

Further, it is hollow out among the collet and two holders.

Compared with the existing technology, dead-weight cable described in the utility model turns round correction roller rack with following excellent again Gesture：

Dead-weight cable described in the utility model turns round correction roller rack again, to be fixed on holder by cable dead weight On, the manufacturing cost of device entirety is reduced, not only can be with fixing bracket by collet, but also can be mitigated by intermediate hollow design The weight of collet, the twice stud being equipped with by each holder enhance support strength of the holder for cable, holder and bottom Support is made integral of welding manner；By both sides with the roller bearing being highly equipped with, make device that there is more stable balance, Support on stress, while the hollow design being equipped with by holder are integrally provided for structure, weight support frame can be mitigated, passed through The one-directional rotation of roller bearing may be implemented in the connection of unilateral bearing and roller bearing.

The utility model will be described in detail below with reference to the accompanying drawings and embodiments.

Dead-weight cable turns round correction roller rack again, as shown in Figs 1-4, including collet 101, support element and multiple roller bearings 301；

Support element is arranged on collet 101, and multiple roller bearings 301 are arranged on support element, and roller bearing 301 and support element are equal It is connected for one-directional rotation, the space that can accommodate one or more cable widths is equipped between adjacent roller bearing 301.

There are two roller bearing 301 is set, 301 left and right sides of each roller bearing is equipped with 3011 roller carrier shaft 3011 of roller carrier shaft and passes through list Left and right sides holder 201 is connected to bearing 3012, two 301 height of idler wheel are identical, and device is made to have more stable balance.

Two roller bearings 301 are only capable of being one-directionally rotated.

Support element includes two holders 201, and two holders 201 are symmetricly set on 101 left and right sides of collet, each holder The U-lag of cable can be placed by being equipped on 201, the twice stud being equipped on each holder 201, and enhancing holder is for cable Support strength.

Holder 201 is welding with collet 101.

It is hollow out among collet 101 and two holders 201, the weight of collet 101 and holder 201 can be mitigated.

The working method of this example

Cable is placed into the cable installed position 601 between multiple roller bearings 301, idler wheel 301 is lighter using relative weight Nylon material make, and nylon material is smaller to the abrasion of Exterior cable insulating layer.Per 3011 inside installation two of roller carrier shaft Unilateral bearing 3012, idler wheel 301 are that can only be rotated to a direction after being slightly under pressure, and use spanner with belt at this time Cable is carried out in correcting process, cable cannot be inverted by after the frictional force of gland 401 and the frictional force of idler wheel 301, to Achieve the effect that cable does not reverse after turning cable by anticipation direction, roller carrier shaft 3011 makes of 45# carbon steels, and both sides are with two Nut is clamped with holder 201, and gland 401 bends after being cut with 4mm steel plates and is welded, and closes gland and suitably tightens butterfly spiral shell Mother 1022, cable is turned with spanner with belt by multiple torsion direction, and cable, which is carried out multiple turn round, to be corrected, and many labours can be save.

The above is only the preferred embodiments of the present utility model only, is not intended to limit the utility model, all in this practicality Within novel spirit and principle, any modification, equivalent replacement, improvement and so on should be included in the guarantor of the utility model Within the scope of shield.
