Description

Cable support subassembly is turned round to inside big cable of wind power tower

Technical Field

The utility model belongs to the field of wind driven generators, and relates to a large cable twisting support assembly inside a wind power tower.

Background

In order to reduce the cost in the wind driven generator, the cable length is more feasible by increasing the height of the cable platform. In the process of lifting the wind generating set button cable platform height, along with the reduction of the radius of the tower, the installation space of a plurality of button cable brackets in the prior art is possibly insufficient in the same plane, so that the cable twisting bracket structure needs to be optimized, and the button cable brackets in the tower need to be rearranged. The cable twisting supports in the existing tower are four in total (two for each large cable button cable support and two for each small cable button cable support), and corresponding posts need to be welded on the inner wall of the tower for matching installation.

The prior art has the technical defects that: 1) the cable twisting supports in the tower are large in number, the relative positions of the support lapping columns are easy to weld wrongly, the cable twisting supports in the same plane in the cylinder are three, and when the diameter of the tower cylinder at the installation position is small, cable buttons are used for the supports to interfere with risks. 2) The large cable twisting support inside the tower is high in assembly difficulty, and once the size of the erection column is slightly inaccurate, the erection column cannot be installed. 3) The welding seam of the large cable twisting bracket in the tower is arranged outside the assembly, so that the cable is easy to be damaged.

Disclosure of Invention

In order to overcome the defects of the prior art, the utility model provides the large cable twisting support assembly in the wind power tower, so that the internal space of a tower barrel is saved, the large cable twisting support assembly is also suitable for installing a cable support at a position with a smaller diameter in the barrel, and the cost is saved; the risk of welding errors at the position of the large cable button cable support welding column is reduced.

The technical scheme adopted by the utility model for solving the technical problems is as follows:

the utility model provides a cable bracket component is turned round to inside big cable of wind power tower, includes a support ring and two backup pads, the support ring breach is down, the both sides of support ring are the joint support board respectively, be equipped with waist type hole in the backup pad.

Furthermore, the support ring is welded with the support plate, and welding seams are located on two end faces of the support ring.

Still further, the cable bracket component is turned round to big cable still includes support ring protection rubber and backup pad protection rubber, the support ring is fixed on the support ring with glue, backup pad is fixed in the backup pad with glue for the protection rubber.

The large cable twisting support assembly further comprises a bolt assembly, and the bolt assembly penetrates through a waist-shaped hole in the large cable button cable support assembly to be fixed with the support arm lapping column.

Three waist-shaped holes are formed in the supporting plate, and the vertical arrangement distance of the three waist-shaped holes is 180 mm.

The bolt assembly includes a hex bolt, two washers and a lock nut.

The utility model has the following beneficial effects: 1. the number of cable twisting supports is reduced, the occupied space is saved, the risk of welding errors at the positions of the support columns is reduced, and the cable twisting support is more favorable for mounting the cable twisting support when the radius of the tower drum is smaller; 2) the adjustability of the large cable twisting support is increased, and the size precision of the welding position of the overlapping column can be properly relaxed. 3) The welding seam of the large cable twisting support is optimized, the large cable twisting support is prevented from being in contact with the cable, and the protection to the cable is increased.

Detailed Description

The utility model is further described below with reference to the accompanying drawings.

Referring to fig. 1 to 7, the large cable twisting bracket assembly inside the wind power tower comprises a support ring 1 and two support plates 2, wherein a gap of the support ring 1 faces downwards, two sides of the support ring 1 are respectively connected with the support plates 2, and waist-shaped holes are formed in the support plates 2.

Further, the support ring 1 is welded with the support plate 2, and the welding seam is positioned on the outer side of the support plate 2.

Still further, the cable bracket component is turned round to big cable still includes support ring protective rubber 3 and backup pad protective rubber 4, support ring protective rubber 3 is fixed on support ring 1 with glue, backup pad protective rubber 4 is fixed in backup pad 2 with glue.

The large cable twisting support assembly further comprises a bolt assembly 5, and the bolt assembly 5 penetrates through a waist-shaped hole in the large cable button cable support assembly to be fixed with the support arm lapping column 6.

Three waist-shaped holes are formed in the supporting plate 2, and the vertical arrangement distance of the three waist-shaped holes is 180 mm.

The bolt assembly includes a hex bolt, two washers and a lock nut.

In the embodiment, the number of the cable twisting supports is reduced to two, the risk of welding errors of the positions of the large and small cable buttons and the support welding posts is reduced, the internal space of the tower is saved, the cable twisting support is also suitable for installing the cable support at the position with the smaller inner diameter of the tower, and the cost is saved. The support arm lapping column adopts a plate-shaped lapping piece, can bear a cable with larger weight, and the waist-shaped hole formed in the large cable twisting support can be properly adjusted to be beneficial to installation. The welding seam between cable support ring and the backup pad is twisted to the cable in the bracket component outside, does not have direct contact's risk with the cable, has increased the protection to the cable.

The embodiments described in this specification are merely examples of implementations of the inventive concepts, which are intended for illustrative purposes only. The scope of the present invention should not be construed as being limited to the particular forms set forth in the examples, but rather as being defined by the claims and the equivalents thereof which can occur to those skilled in the art upon consideration of the present inventive concept.
