Description

A spacer bar replacement jig

technical field

The utility model relates to a special tool for electric power maintenance, in particular to a tool for replacing spacer rods of power transmission lines.

technical background

At present, 500kV transmission lines generally use four-split or six-split conductors, and ultra-high-voltage transmission lines with voltages higher than 500kV use six-eight-split or more split conductors. In order to ensure that the spacing between the split wire harnesses remains unchanged to meet the electrical performance and ensure the flow capacity, spacers are installed at a certain distance in the span. Installing the spacer can also play a certain role in restraining the vibration of the wire and the breeze vibration. A large number of conductor spacers are used on the 500kV transmission line. There are many types of spacers, and there is no uniform replacement tool, and some spacers have no construction holes. General spacer replacement tools cannot be used, and spacers without construction holes cannot be replaced; replace spacers at the same time There is no common tool, which leads to inconsistent working methods of maintenance personnel. They need to be replaced according to their own experience. The working methods are different, neither standard nor standardized, and it is not conducive to the induction training of new employees.

Utility model content

The purpose of the utility model is to provide a spacer replacement jig with simple structure, convenience, labor saving and universality.

The fixture for replacing the spacer of the utility model includes a hook, wherein it also includes a transmission screw; one end of the hook is provided with a folded edge, and the other end of the hook is provided with an end surface formed by bending toward the folded edge; The flange is provided with a threaded hole adapted to the transmission screw, and one end of the transmission screw passing through the threaded hole is connected with a clamping platform, and the end surface is opposite to and parallel to the clamping platform.

Furthermore, in the fixture for replacing spacer rods, a sleeve is fixedly connected to the end of the transmission screw away from the clamping platform, which is convenient for the operator to rotate the transmission screw with less effort.

The beneficial effects of the utility model:

In the spacer rod replacement fixture provided by the utility model, the end face formed by the hook bending to the edge is parallel to the clamping platform at one end of the transmission screw, and the operator only needs to rotate the transmission screw to realize the automatic advancement of the clamping platform until the clamping platform is in contact with the clamping platform. The hook bends to the end surface formed by the folded edge to clamp the side of the spacer bar, which is convenient for maintenance personnel to take out the screw and replace the spacer bar; therefore, the device has simple structure, convenient operation and labor-saving, and no external power source is needed, and the weight is greatly reduced and easy to carry , can be adapted to the replacement of multi-split conductor spacers of different voltage levels, and has versatility.

Detailed ways

In order to make the purpose, technical solution and advantages of the utility model more clear and definite, the utility model will be further described in detail below with reference to the accompanying drawings and examples.

Example 1:

As shown in Fig. 1, the fixture for replacing the spacer in this embodiment includes a hook 1, which also includes a drive screw 2; one end of the hook 1 is provided with a flange 11, and the other end of the hook 1 is provided with a bending direction The end face 12 formed by the flange 11; the flange 11 is provided with a threaded hole 13 compatible with the transmission screw 2, and the end of the transmission screw 2 passing through the threaded hole 13 is connected with a clamping platform 21, so The end surface 12 is opposite to and parallel to the clamping platform 21 , and the end of the drive screw 2 away from the clamping platform 21 is fixedly connected with a sleeve.

Each wire is fixed on the spacer bar by a plurality of wire clamps corresponding to the positions of the corresponding split wires. When replacing the spacer, generally the new spacer is installed first, and then the old spacer is disassembled. When installing a new spacer, first remove the closed pins at the clamps of each line of the spacer, open the movable snap rings of each clamp, hang each clamp on the corresponding split wires, and then use this utility The new type presses the movable snap ring back to its original position in turn, and reinserts the closed pin.

The specific operation process is as follows: snap the hook 1 into the elliptical groove on the fixed side of the clamp, make the movable clasp wrap the wire, and snap the clamping platform 21 fixedly connected with the transmission screw 2 into the corresponding elliptical groove on the movable clasp Then, by rotating the sleeve fixed on the drive screw 2, the clamping platform 21 presses down the movable snap ring until the end of the movable snap ring passes over the installation hole of the closed pin on the fixed side of the wire clamp, Insert the dead pin to lock the movable snap ring. After installing the closed pin, reversely rotate the adjustment handle to make the drive screw return.

When removing the old spacer, because the clamp is under stress, its movable snap ring is pressed by the closed pin, so when disassembling, the movable snap ring should be pressed down first to make it break away from the closed pin, and then the closed pin should be pulled out. out. The depressing process of the movable snap ring is the same as the aforementioned process.

In summary, the utility model is easy to operate and simple in structure, and the use of the transmission screw does not require external power, which makes the utility model device light in weight and easy to carry; reduces the labor intensity of operators, and improves the work of installing and replacing spacers. Efficiency provides a reliable basis for later defect management and processing. The utility model of the invention is applicable to various types of spacer rods, and solves the problems of lack of common tools for replacing spacer rods and excessive physical exertion of staff. Work provides better and more reliable services.

The above detailed description is a specific description of the feasible embodiment of the utility model. This embodiment is not used to limit the patent scope of the utility model. Any equivalent implementation or change that does not deviate from the utility model shall be included in this case within the scope of the patent.
