Embodiment

[0012] An insulating telescopic pin puller includes an outer insulating sleeve 3 and an inner insulating sleeve 4 that can move therein. The fixed jaws 5 are welded on the tubular fixed pliers arm 8 , and the tubular fixed pliers arm 8 is threadedly connected to the inner surface of the front end of the outer insulating sleeve 3 . The movable jaw 6 is welded to the rod-shaped pincer arm 7, the pincer arm 7 is inserted into the front end of the inner insulating sleeve 4, connected as a whole with the guide pin 9, and the guide pin 9 is exposed to a part of the surface of the inner insulating sleeve 4. The inner surface of the front end of the outer insulating sleeve 3 is processed with an axial guide groove 10, and the part of the guide pin 9 exposed on the surface of the inner insulating sleeve 4 cooperates with the guide groove 10 to realize the movement of the inner insulating sleeve 4 along the outer insulating sleeve 3. axial movement. A nut 11 is installed at the end of ...

Abstract

The invention relates to insulating telescopic pin pulling pliers, which is characterized by comprising an outer insulating sleeve 3 and an inner insulating sleeve 4 capable of moving in the outer insulating sleeve 3, wherein a fixed gripper arm 5 is installed at the front end of the outer insulating sleeve 3; a movable gripper arm 6 is installed at the front end of the inner insulating sleeve 4; a guide groove 10 is machined on an inner surface of the outer insulating sleeve 3; the inner insulating sleeve 4 is provided with a guide pin 9 matched with the guide groove 10; a nut 11 is installed at the tail end of the inner insulating sleeve 4; a screw rod 12 is matched with the nut 11; and a limiting rod 2 is installed on the screw rod 12 and located at the outer side of the tail end of the outer insulating sleeve 3. With the adoption of the insulating telescopic pin pulling pliers, an operator can stand on a ground to examine and repair top electrified equipment without entering an electric field, thus potential personal safety hazards are eliminated, and work efficiency is improved.

Description

technical field [0001] The invention belongs to the technical field of power transmission and transformation, in particular to a tool for working with live lines. Background technique [0002] In the past, live work on transmission lines, such as replacing insulating porcelain bottles, clamping pins with ground wires, etc., generally used human body equipotential operations. However, due to the small air gap, the safe distance cannot be guaranteed, so it must be dealt with in a power outage. If the power outage is dealt with, it will bring certain economic losses to the enterprise and society. Contents of the invention [0003] In order to solve the problem of potential safety hazards when personnel enter the electric field for equipotential operation during the maintenance of transmission lines, the following technical solutions are proposed: [0004] An insulated telescopic pin puller, its special feature is that it includes an outer insulating sleeve 3 and an inner in...
