Problems solved by technology

At present, most of the deicing devices in the existing technology are cumbersome. If the deicing device is attached to the wire, the quality of the deicing device will increase the load-bearing load of the power grid. At present, the deicing device is mostly for a single power grid line. If there are split wires or brackets between the wires, it may hinder the de-icing operation

Embodiment 1

[0038] A ring machine for electric power maintenance used in bad weather, including a frame with openings for placing wires into the frame, four rollers inside the frame, the middle surface of the rollers is concave at both ends of the rollers , so that the roller can be placed on the wire to roll and drive the device to walk and maintain a certain stability. The frame on both sides of the roller is provided with arc hoops, which are connected to the frame through the cylinder, and the sides of the arc hoop are blade edges. . Dispose the wire from the opening to the roller in the frame, control the cylinder to clamp the arc hoop on the wire, move the device, and use the edge of the arc hoop to perform deicing operations.

[0039] The frame is a circular frame, and the cross-section of the frame is circular.

[0040] The frame is aluminum frame. The device can complete the deicing operation with a relatively light weight, and at the same time can ensure a certain strength to ...

Embodiment 2

[0042] A ring machine for power maintenance used in severe weather, its structure is the same as that described in Embodiment 1, the difference is that the roller is provided with a heating wire. The heating wire can initially melt the ice and snow on the wires in contact with the rollers, assisting in deicing.

Embodiment 3

[0044] A ring machine for power maintenance used in bad weather, its structure is the same as that described in Embodiment 1, the difference is that two adjacent rollers are connected to the horizontal plate, and the two ends of the horizontal plate are provided with limit columns, and the limit columns It is connected with the frame, and the middle part of the horizontal plate is provided with a threaded rod. Because the rollers have a certain bending arc, in order to put the four wires in smoothly, before putting the wires in, the horizontal plate moves toward the frame through the helical movement of the threaded rod and the limit function of the limit post, thereby driving the two rollers. The column also moves towards the direction of the frame, and the distance between it and another roller increases. After putting in the wire, rotate the threaded rod in the opposite direction and push the horizontal plate to move in the opposite direction, so that the concave surface of ...

Abstract

The invention relates to a power maintenance annular machine applied to a severe weather and an application method of the power maintenance annular machine, and belongs to the technical field of power maintenance equipment. The device comprises a framework, wherein an opening is formed in the framework and is used for placing a wire in the framework, four rollers are arranged in the framework, a surface of a middle part of each roller is sunken at two ends of the roller so that the roller can be placed on the wire and rolls to drive the device to travel and keep stable to a certain extent, arc loops are arranged on the frameworks at two sides of each roller and are connected with the frameworks by air cylinders, and side edges of the arc loops are blade edges. The wire is placed at the rollers in the framework from the opening, the arc loops are clamped on the wire by controlling the air cylinders, the device is moved, and deicing operation is performed by means of the blade edges of the arc loops; the device is easy to operate, is good in deicing effect and high in applicability, is particularly applied to four lines and is convenient to carry and install in a site, installation convenience is achieved, labor and material cost are reduced, and an accidental injury probability of an operator is reduced.

Description

technical field [0001] The invention relates to an electric power maintenance ring machine applied in severe weather and an application method thereof, belonging to the technical field of electric power maintenance equipment. Background technique [0002] With the popularization and development of electric power communication, the popularization area of ​​the national high-voltage line network continues to expand. my country has a vast territory, and the lines pass through different geographical environments. Affected by some regional environments and the alternation of seasons, the line network will encounter low temperature and ice and snow weather. [0003] Long-term low temperature, rain and snow will form ice on the high-voltage wire network, and severe ice-covering will cause failures such as wire drop, collapse, and disconnection, causing accidents such as tripping and power supply interruption, which not only cause economic losses to the State Grid, but also to people...
