Abstract
The utility model relates to an insulating rod adapter assembly, including tie-ins at two ends of the insulating rod characterized in that one tie-in consists of a plinth and a plug, the other tie-in consists of a plinth and a connection plate that fits the plug, and there are communicating pores in the center of the plug and the connection plate. The characteristic of the adapter assembly is that the rods are linked by means of hinge, thereby improving the flexivity of the rods so that the rods can distort when sway with the high voltage wires. Therefore, the rods are not easy to break off, which guarantees the operational security and extends the operating life.
Description
Technical field
The utility model relates to a kind of tools for live working, especially for the insulation pull rod piecing of changing high-tension line straight line insulator string.
Background technology
In electric power system, the straight line insulator string of charged for replacement 220kv and above high-tension line need promote high voltage cable by leading screw and the interconnective pull bar of more piece.Lean on being threaded of its joint between the existing insulated tension pole, the problem of existence is: adopt the pull bar after being threaded, the amount of deflection that himself produces is little, when high voltage cable takes place acutely to rock, pull bar is fractureed.
Summary of the invention
The purpose of this utility model is to provide a kind of insulation pull rod piecing assembly that increases whole pull bar amount of deflection.
The purpose of this utility model is achieved in that a kind of insulation pull rod piecing assembly, comprise the joint that is connected the insulating bar two ends, it is characterized in that one of them joint is to be made of plinth and joint fork, another joint is to be made of plinth and the adapter plate that can match with the joint fork, and the center position of joint fork and adapter plate has the connecting hole of perforation.
Characteristics of the present utility model are: adopt this adapter assembly, can make between pull bar and the pull bar to be connected in hinged mode, increased the amount of deflection of whole pull bar, during operation, can rock with high voltage cable and deform, therefore frangibility not, guarantee job safety, the useful life of having improved pull bar.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the vertical view of Fig. 1.
Embodiment
Below in conjunction with accompanying drawing the utility model is done further auspicious stating:
As shown in Figure 1 and Figure 2, the outside, two ends of insulating bar 1 has joint 2 respectively, and one of them is to be made of plinth 3 and joint fork 4, and another is to be made of plinth 3 and the adapter plate 5 that can match with the joint fork.The center position of joint fork and adapter plate has the connecting hole 6 of perforation.Being connected between pull bar and the pull bar is to be inserted in the joint fork of another pull bar by the adapter plate with a pull bar, connects together with link again, and this connected mode has increased the amount of deflection of whole pull bar.
