Abstract

The utility model discloses a connecting device for a crawling ladder of a wind-driven generator tower, belonging to the technical field of wind power generation. The connecting device comprises a magnetic body and a connecting member connected with the crawling ladder, wherein multiple segments of the crawling ladder are connected with one another and are arranged in the tower, and each segment of the crawling ladder is provided with the connecting device; and the connecting member is connected with one end of the magnetic body, and the other end of the magnetic body is fixed on the inner wall of the tower through a magnetic force. Due to adoption of the structure of the connecting device, when welding parts of the inner surface of the tower are reduced, the strength of the tower can be improved, and the service life of the tower can be prolonged. The connecting device is simple and feasible to mount and convenient to implement.

Description

The linkage of wind-driven generator tower frame cat ladder
Technical field
The invention belongs to technical field of wind power generation, particularly relate to a kind of linkage of large-scale wind driven generator pylon cat ladder.
Background technology
Usually, wind-driven generator tower frame can be built into according to multiple different principle, for example tubular steel tower, trellis mechanism's pylon and even concrete towers.It is conical that most of large-scale wind driven generator pylons are generally, in order to increase intensity and save simultaneously material, the scene of every joint pylon transportation is bolted together.The inside cat ladder of existing pylon is bolted cat ladder by the junction plate of pylon inner surface welding.The connected mode of this direct welding can slacken structure, the intensity of pylon, and shortened the application life of pylon.
Summary of the invention
For the technical problem of above-mentioned existence, the invention provides a kind of linkage of wind-driven generator tower frame cat ladder, he has syndeton now by change, and making does not have pad on pylon, strengthen the intensity of pylon, extends the application life of pylon.
The objective of the invention is to be achieved through the following technical solutions:
A kind of linkage of wind-driven generator tower frame cat ladder, comprise magnet and the connector that is connected cat ladder, described cat ladder is that multistage interconnects and be placed in pylon, every section cat ladder is provided with described linkage, described connector is connected with magnet one end, and the magnet other end is fixed on the pylon inwall by magnetic force.
Described magnet and connector have multiple syndeton:
The first structure: described magnet is hollow-core construction, and it is connected with connector by being placed in the block connection in magnet.
The second structure: described magnet is hollow-core construction, and its upper end has the bar-shaped trough that can insert connector, is fixed with the block of inserting in magnet at the connector end.
The third structure: the link of described magnet and connector is with hollow-core construction, and the upper surface of magnet has T-shaped groove, is fixed with the block of inserting in magnet at the connector end, and described connector and block coordinate with the T groove respectively.
Described magnet is ndfeb magnet or permanent samarium cobalt permanent magnet body.
Beneficial effect of the present invention is:
1. reduce pylon inner surface weldment, improve tower frame strength, increase the service life.
2. the present invention installs simplely, be convenient to implement, and connector has multiple syndeton with magnet, makes simply, and is easy to connect.

The specific embodiment
The invention will be further described below by embodiment and accompanying drawing.
Embodiment 1: as shown in Figure 1, cat ladder 4 of the present invention interconnects and is placed in pylon 1 for multistage, every section cat ladder 4 is provided with described linkage, described linkage comprises magnet 2 and the connector 3 that is connected cat ladder 4, described connector 3 is connected with magnet 2 one ends, and magnet 2 other ends are fixed on pylon inwall 11 iron plates by magnetic force.
Described magnet 2 is hollow-core construction, and they are connected with connector and connect by the block 5 that is placed in magnet 2.Described magnet 2 is ndfeb magnet or permanent samarium cobalt permanent magnet body.
Embodiment 2: as Fig. 1, Fig. 2, shown in Figure 3, this example as different from Example 1: described magnet 2 is hollow-core construction, and its upper end has the bar-shaped trough 21 that can insert connector, is fixed with the block 5 of inserting in magnet 2 at connector 3 ends.
Embodiment 3: as Fig. 1, shown in Figure 4, this example is as different from Example 1: the link of described magnet 2 and connector 3 is with hollow-core construction, the upper surface of magnet 2 has T-shaped groove 22, is fixed with the block 5 of inserting in magnet 2 at the connector end, and described connector 3 and block 5 coordinate with the T groove respectively.
