Description

Transmission line maintenance platform

technical field

The utility model relates to the technical field of electrical equipment, in particular to a power transmission line maintenance platform which can greatly reduce labor intensity and improve safety during the construction and maintenance of power transmission line equipment.

Background technique

As the voltage level of transmission lines rises, the number or length of insulators also increases step by step, and the difficulty of installing or replacing vibration-proof hammers, wire clamps, and insulators during construction also gradually increases. Especially in recent years, in order to improve the anti-pollution flashover capability of transmission lines, more and more synthetic insulators are used in transmission lines. If traditional construction methods are used, the synthetic insulators will be damaged to a certain extent during the installation or replacement of anti-vibration hammers. The damage will affect the normal operation of the transmission line.

In addition, in order to increase the maintenance speed of transmission lines and reduce the power outage time, it is an effective way to improve the reliability of power supply of transmission lines. As shown in Figure 7, the right side of the figure adopts the traditional construction method. The electrician who repairs the equipment climbs on the line to repair the insulators, anti-vibration hammer and other equipment. This maintenance method can not help but labor intensity and high risk factor. It is also difficult to increase the speed of maintenance.

Utility model content

In order to improve the safety during line construction and maintenance, reduce wear on composite insulators, improve work efficiency, and shorten power outage time, the utility model provides a brand-new transmission line maintenance platform.

In order to achieve the above-mentioned technical purpose, the utility model takes the following technical solutions:

A power transmission line maintenance platform includes: a frame body and suspension mechanisms at both ends, the frame body includes at least two frame body sections, the frame body section is composed of two support rods and a crosspiece, and the two support rods are arranged in parallel and fixedly connected by the crosspiece , the subsections of the frame body are connected via hinges; the suspension mechanism is composed of a connection part and a suspension part, both of which are isosceles triangle frames, and the connection part and the suspension part are connected at the top corners, The bottom edge of the connecting part is provided with a sleeve which cooperates with the crosspiece or the supporting rod, and the bottom edge of the hanging part is provided with a hook.

In the power transmission line maintenance platform of the utility model, a shaft sleeve is vertically provided at the top corner of the connection part, and a rotating shaft is vertically provided at the top corner of the suspension part, and the connection part and the suspension part are hinged to the rotation shaft through the shaft sleeve.

In order to firmly connect the power transmission line maintenance platform of the present invention with the wires, cross-arms, etc., a locking device is also provided on the hook. The locking device is mainly realized in two ways. Hinged on the body can seal the movable rod at the opening of the hook body; secondly, insert a latch that can seal the opening of the hook body on the hook body of the hook.

The beneficial effects of the utility model are as follows: 1. The frame body of the utility model is hinged by the small parts of the frame body, not only the length of the frame body can be adjusted according to the needs of daily maintenance, but also the foldable frame body facilitates the installation of the device. 2. According to the requirements of safety and quickness of maintenance, this device can be made of Q235 steel or insulating material; 3. Improve the construction speed, reduce the labor intensity of operators, and reduce the synthetic The wear of insulators improves the safety of workers during construction.

Detailed ways

Below in conjunction with accompanying drawing, the utility model is further described.

The power transmission line inspection and maintenance platform shown in Figure 1 includes a frame body and a suspension mechanism connected to both ends of the frame body (see Figure 7). The frame body a is generally in the shape of a ladder frame, including at least two frame body sections , the subsection a of the frame body is composed of two support rods a1 and a crosspiece a2, the two support rods a1 are arranged in parallel and fixedly connected by three crosspieces a2, and the subsections a of the frame body are connected through the hinge a3. Dividing the frame body into several frame body sections is hinged mainly for the convenience of carrying and handling. As shown in Figure 2, it is a schematic diagram of the folded state of the frame body. When the frame body sections are connected, the rotation range is 180-degree hinge, so the frame will not be over-rotated after being laid flat between the subsections, and will not affect the shape of the frame.

The suspension mechanism is composed of a connecting part (see Figure 3, Figure 4) and a suspension part (see Figure 5, Figure 6). The connecting part and the hanging part are both isosceles triangle frames (the best choice is an equilateral triangle frame), wherein a shaft sleeve b1 is vertically arranged on the top corner of the connecting part, and two sleeves b2 are arranged on the bottom edge of the frame; The top corner of the hanging part is vertically provided with a rotating shaft c1, and the bottom edge of the frame is provided with two hooks c2; the connecting part and the hanging part are hinged with the rotating shaft through the bushing, and this hinge method can ensure that the connecting part and the hanging part Flexible connections between departments.

In order to firmly connect the power transmission line maintenance platform of the utility model with the wires, cross arms, etc., a locking device is also provided on the hook. As shown in Figure 6, the locking device hinges a movable rod c3 on the hook body of the hook, and the movable rod c3 can seal the opening of the hook body, and the device ensures construction safety.

Another locking form of the utility model is to insert a latch that can seal the opening of the hook body on the hook body of the hook.

When in use, as shown in Figure 7, unfold the scaffold in the folded state during use, and when working on the tension pole tower, hang the hooks at both ends of the utility model on the fittings at the front and rear ends of the insulator string respectively, so that the operator can sit on the Insulators and anti-vibration hammer construction are carried out on the bracket. The movable rod on the hook body is used to firmly connect the transmission line maintenance platform with the wire and the cross arm to ensure construction safety.

When using the line "scaffolding" to work on the straight pole tower, one end of the hook is hung on the wire, and the other end is hung on the appropriate part of the iron tower. The operator can sit on the bracket and carry out the construction of the insulator and the shockproof hammer.
