Problems solved by technology

[0002] At present, the replacement of double-string insulators in the power supply bureau is relatively heavy manual labor. Large-scale tools are generally used to replace them, and it is difficult to ensure construction safety during the use of large-scale tools.
In this way, the efficiency of line maintenance work is low, the handling of construction tools is difficult, and the safety hazards that endanger construction are relatively large.

Embodiment Construction

[0009] figure 1 , figure 2 As shown, the double-string insulator replacement tool is composed of a pull plate 1, a retractable pull rod 2 and a pull ring connected in sequence; the structure of the pull plate 1 is: the adjusting bolt 1c is connected to the left ends of the two parallel plates 1a, 1b, and the two parallel plates A fixed bolt 1d is connected to the right end, and there are multiple adjustment holes 1e on the two parallel plates 1a, 1b; The left end sleeve of 2b is hung on the fixed bolt 1d, and the right end sleeve of the right rod 2c is hung on the pull ring. Holes are all arranged on the left bar 2b and the right bar 2c, hang on corresponding bolts through the holes. The pull ring is a ring or the structure is (the structure in the figure): there are two ear plates on the cuboid plate 3a, and the bolts 3b are fixed on the two ear plates. The left rod and the right rod can adopt one to be screwed with the cylinder and the other to be fixed with the cylinder...

Abstract

The invention discloses a tool for changing two strings of insulators. The tool consists of a pull plate, a telescopic pull rod and a pull ring which are connected in sequence, wherein the structure of the pull plate is that: an adjustment bolt is connected to left ends of two parallel plates; a fixing bolt is connected to the right ends of the two parallel plates; a plurality of adjustment holes are formed in the two parallel plates; the structure of the telescopic rod is that: a left rod and a right rod are screwed on the left end and the right end of a barrel body respectively; the left end of the left rod is sleeved and hung on the fixing bolt; and the right end of the right rod is sleeved and hung on the pull ring. The tool has the characteristics of simplicity, practicability and convenience for carrying, and is a tool special for changing two strings of insulators at 220 kV or below.

Description

technical field [0001] The invention relates to a tool for maintaining electric fittings, in particular to a special tool for replacing double insulator strings of 220kV and below. Background technique [0002] At present, the replacement of double-string insulators in the power supply bureau is relatively heavy manual labor. Large tools are generally used to replace them, and it is difficult to ensure construction safety during the use of large tools. Like this, there is the problem that the efficiency of line inspection and maintenance work is low, and construction implement implement is carried more difficult, endangers the problem that the safety hidden danger of construction is bigger. Contents of the invention [0003] The purpose of the present invention is to provide a simple, practical and portable double string insulator replacement tool. [0004] The purpose of the present invention is achieved in this way: a double-string insulator replacement tool is composed...
