Abstract

The invention discloses a T-type cable connector quick pulling-out device and a pulling-out method. The pulling-out device comprises an inflation pump, a plug and a valve core. The pulling-out method comprises the steps of 1), taking an original plugging head from a T-type cable connector; 2), enabling the plug of the T-type cable connector quick pulling-out device to be connected with the T-type cable connector; 3), connecting the inflation pump, the valve core and the plug in sequence; 4), inflating the T-type cable connector through the inflation pump; and 5), stopping inflation when a connection part of the T-type cable connector and a wall bushing on a ring main unit is loosened, and pulling the T-type cable connector out from the wall bushing. According to the invention, the junction of the T-type cable connector and the wall bushing is enabled to be loosened by using air pressure, so that the T-type cable connector can be pulled out from the wall bushing on the ring network cabinet easily, and the work efficiency can be greatly improved. In addition, the T-type cable connector is uniformly stressed in the pulling-out process, and a cable head is not damaged.

Description

technical field [0001] The invention relates to a tool and a method for using the tool, in particular to a tool for pulling out a cable joint and a method for pulling out a cable joint. Background technique [0002] In the power distribution maintenance work, it is often necessary to pull out the cable T-shaped head from the wall bushing on the ring network cabinet for cable testing or replacement of the cable T-shaped head, and the cable T-shaped head will be coated with grease during installation , The seal is tight, so that the connection between the cable T-shaped head and the wall bushing on the cabinet is particularly firm. In the traditional maintenance method, since there is no special tool, it often requires several workers to work together to pull out the cable T-head because there is no special tool, which consumes more manpower and lower work efficiency. And in the pulling out process, the force on the cable head is uneven, which easily causes damage to the cabl...
