Description

An insulating flat ladder suspension device for power poles and towers

technical field

The invention relates to a suspension device used by electric power workers for high-altitude operations, in particular to an insulating flat ladder suspension device for power poles and towers.

Background technique

Transmission lines occupy an important position in the power system. Transmission line workers are mainly engaged in the construction, operation, maintenance and other work of power transmission lines. Among these tasks, many of them are completed on the line iron tower. The height of the line iron tower is basically 18 Work at heights above 1 meter.

At present, the staff working on the iron towers are protected by safety belts and other protective devices, and they stand or lean on the iron towers for construction or maintenance, because line workers often work on the iron towers for a long time, so they work against the iron towers for a long time Not only is it unfavorable for workers to operate, but it is also prone to work fatigue, resulting in safety accidents.

Contents of the invention

An insulating flat ladder suspension device for power pole towers of the present invention overcomes the defects of the prior art, and provides an insulating flat ladder suspension device for power pole towers used for long-time work at high altitudes.

An insulating flat ladder suspension device for power poles and towers according to the present invention includes a shaft. Both ends of the shaft are fitted with bushes that can rotate along the shaft. A connecting rod is fixed on the bushing, and the top of the connecting rod Bending into a hook shape and used for hanging, the two ends of the shaft extend outwards, and ring connectors are respectively fixed on the extended shafts, so that the top hook of the connecting rod is hung on the triangular support frame of the line iron tower, and the ring The connecting piece is connected and fixed with the two ladder beams of the ladder, so that the staff can sit on the ladder for construction and maintenance, so that the staff can work more conveniently and are not prone to work fatigue.

The shaft includes an integrally formed first horizontal shaft, a vertical shaft and a second horizontal shaft, the first horizontal shaft and the second horizontal shaft are fixed by the vertical shaft, and the first horizontal shaft and the second horizontal shaft are relatively vertical The center of the shaft rotates up and down, and the sleeves are respectively set on the first horizontal shaft and the second horizontal shaft. In this way, since the first horizontal shaft and the second horizontal shaft rotate up and down relative to the center of the vertical shaft, it can pass Adjust the positions of the first horizontal axis and the second horizontal axis to adapt to different triangular support frames, effectively avoiding that the ladders are not stable due to the different triangular support frames of different line towers, so that the ladders are on the same plane.

The outsides of the shafts, bushings, connecting rods, and annular connectors are covered with insulating skins, which are used to prevent leakage, static electricity, and the like.

Compared with the prior art, the advantage is: using the insulating flat ladder suspension device for power poles and towers of the present invention, the staff can directly sit on the ladder for operation without directly leaning on the iron tower, which is not easy to cause fatigue and avoids safety hazards. Accidents, this machine can also be used on different line iron towers, the operation is simple, it can not only improve the work efficiency of workers, but also reduce the occurrence of safety accidents.

Detailed ways

The specific implementation manners of the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

Embodiment one:

As shown in Figures 1 and 2, an insulating flat ladder suspension device for a power pole tower includes a shaft 1, and both ends of the shaft 1 are fitted with a shaft sleeve 2 that can rotate along the shaft, and a connecting rod 3 is fixed on the shaft sleeve 2 , the top of the connecting rod 3 is bent into a hook 31 and is used for hanging. The two ends of the shaft 1 extend outward, and the extended shaft 1 is respectively fixed with two ring-shaped connectors 5 by nuts 4. The ring-shaped connector 5 consists of two The two semi-arc connecting pieces are fixed by bolts, and the outer sides of the shaft 1, the shaft sleeve 2, the connecting rod 3 and the annular connecting piece 5 are covered with insulating skins.

In the present embodiment, the top hook 31 of the connecting rod 3 is hung on the triangular support frame of the line iron tower. When the triangular support frame is an isosceles triangle, the ladder can be placed on the same plane. The connection is fixed, and the staff can sit on the ladder for construction and maintenance, so that it is more convenient for the staff to work and is not prone to work fatigue.

Embodiment two:

As shown in Figure 3, an insulating flat ladder suspension device for a power pole tower includes a shaft and two bushings 2, and the shaft 1 includes an integrally formed first horizontal shaft 11, a vertical shaft 12 and a second horizontal shaft 13, the first The horizontal axis 11 and the second horizontal axis 13 are fixed by the vertical axis 12, the first horizontal axis 11 and the second horizontal axis 13 rotate up and down relative to the center of the vertical axis 12, and the sleeves 2 are respectively set on the first horizontal axis 11 and the second horizontal axis. On the second horizontal shaft 13, a connecting rod 3 is fixed on the bushing 2, and the top of the connecting rod 3 is bent into a hook 31 for hanging. The ends of the first horizontal shaft 11 and the second horizontal shaft 13 extend outward respectively, The extended part is respectively fixed with an annular connecting piece 5 through a nut 4, and the annular connecting piece 5 is fixed by two semi-arc connecting pieces through bolts, the first horizontal shaft 11, the vertical shaft 12, the second horizontal shaft 13, the bushing 2. The outer sides of the connecting rod 3 and the annular connecting piece 5 are covered with insulating skins.

This embodiment is used when the triangular support frame is a non-isosceles triangle. In order to make the ladder on the same plane, adjust the positions of the first horizontal axis 11 and the second horizontal axis 13 to adapt to different triangular support frames, effectively avoiding Because the triangular support frames of different line iron towers are different, the ladder is not stable, so that the ladder is on the same plane.

The above is only a preferred embodiment of the present invention, it should be pointed out that for those of ordinary skill in the art, without departing from the technical principle of the present invention, some improvements and modifications can also be made, these improvements and modifications It should also be regarded as the protection scope of the present invention.
