Description

Isolation switch lifting device

technical field

The utility model relates to an electric power hoisting tool, in particular to a hoisting device for an isolating switch.

Background technique

In the construction and maintenance of substation equipment, disconnectors are indispensable equipment. When installing or removing the isolating switch, due to the limited space of the site, the use of the crane is limited, and the safe distance between the crane arm and the live area is insufficient, and it is necessary to increase the power failure of adjacent intervals, reducing the reliability of power supply. At present, the staff usually build a scaffolding platform to dismantle the isolating switch, and multiple people pass it to the ground in layers, and then pass the new isolating switch to the isolating switch structure for installation. This installation method leads to a large number of maintenance personnel and high labor intensity, low operating efficiency and long power outage time.

Contents of the invention

The utility model aims to solve the above technical problems, and provides a hoisting device for a disconnector that can reduce maintenance personnel, reduce labor intensity, improve work efficiency, and shorten power failure time.

The technical solution of the utility model is:

A hoisting device for an isolating switch, including a base and a support rod arranged on the base. The flange plate at the end is seated on the flange plate on the support rod, and the positioning holes arranged in the circumferential direction are respectively arranged on the two flange plates, and positioning pins are inserted in the corresponding positioning holes of the two flange plates; A pulley block is installed on the swing arm, a suspension rope is wound on the pulley block, and a suspension hook is arranged at the head end of the suspension rope; a disconnector frame connection frame and a utility pole connection frame are arranged at the lower part of the support rod.

Further, a pressure bearing is arranged between the two flanges on the support rod to reduce the friction between the two flanges, and the swing arm swings flexibly.

Further, the swing arm is composed of a sleeve and a horizontal rod arranged at the top of the sleeve.

Further, a diagonal rod is connected between the bushing and the horizontal rod to enhance the structural strength of the swing arm.

The beneficial effects of the utility model are:

1. Since a swing arm is installed on the upper part of the support rod, a pulley block is installed on the swing arm, and a suspension rope with a hook at the head end is wound around the pulley block, and the isolating switch hooked on the hook is transported to the ground by retracting the suspension rope Or the isolation switch structure reduces the number of maintenance personnel, saves time and labor, low labor intensity, high operating efficiency, and shortens the power outage time; after the isolation switch is transported to the top, the rotating swing arm installs the suspended isolation switch on the isolation switch structure , It is convenient to adjust the installation position of the isolating switch, which further shortens the time for positioning and installing the isolating switch, and improves the efficiency of installing the isolating switch.

2. Since there are positioning holes arranged circumferentially on the flanges on the support rod and the bottom end of the swing arm, after the installation position of the isolating switch is determined, insert the positioning pins into the corresponding positioning holes on the two flanges to prevent the The installation position of the isolating switch is shifted due to the rotation of the swing arm, which ensures the accuracy of the installation position of the isolating switch.

3. Since the isolating switch frame connecting frame and the utility pole connecting frame are arranged at the lower part of the support pole, the isolating switch frame connecting frame is installed on the isolating switch frame, and the utility pole connecting frame is installed on the utility pole where the isolating switch is located, ensuring that the supporting rod The structural stability of the structure prevents dangerous accidents caused by the toppling of the support rod.

detailed description

As shown in the figure, a lifting device for a disconnector includes a base 1 and a support rod 2 welded on the base 1. A swing arm 3 is arranged on the top of the support rod 2. The swing arm 3 is composed of a sleeve 301 and a The horizontal rod 302 at the top of the tube 301 is formed, and the inclined rod 303 is connected between the casing 301 and the horizontal rod 302 to enhance the structural strength of the swing arm 3 . Flanges 4 are respectively welded on the support rod 2 and the bottom end of the casing 301, and a pressure bearing 5 is installed between the two flanges 4 on the support rod 2 to reduce the friction between the two flanges 4, and the swing Arm 3 swings flexibly. And two flanges 4 are respectively provided with circumferentially arranged positioning holes 401, and positioning pins 6 are inserted in the corresponding positioning holes 401 of the two flanges 4; A suspension rope 8 is wound on it, and a suspension hook 9 is tied at the head end of the suspension rope 8;

During operation, first place the isolating switch hoisting device on the ground on one side of the isolating switch structure, and install the isolating switch frame connecting frame 10 on the isolating switch frame through bolts, and fix the utility pole connecting frame 11 on the isolating switch On the utility pole where it is located, maintenance personnel climb to the isolating switch structure to remove the damaged isolating switch, and then rotate the swing arm 3 above the damaged isolating switch to hook the damaged isolating switch through the hook 9 and send it to the ground , and then hook the new isolating switch on the hook 9, pull it to the isolating switch structure through the sling 8, and rotate the swing arm 3 to adjust the position to install the new isolating switch on the isolating switch structure to complete the operation.

The above are only specific embodiments of the utility model, and are not intended to limit the utility model. For those skilled in the art, the utility model can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principles of the present utility model shall be included in the protection scope of the present utility model.
