Clamping arm lead screw tension grip

Abstract

The invention discloses a novel clamping arm lead screw tension grip which is characterized by comprising a draw plate, a draw rod for drawing the draw plate, a pull plate for pulling the draw rod, and a connecting piece, wherein the connecting piece is connected to the pull plate; and the draw plate is provided with a through hole. The clamping arm lead screw tension grip effectively solves the problem that the clamping groove lead screw is incapable of connection and acting on a dead load tester.

Description

[0001] 【Technical field】 [0002] The invention relates to the field of electric power, in particular to a jig for clamping arm screw tension test. [0003] 【Background technique】 [0004] The clamp arm screw is mainly used in the disassembly and replacement of the insulator string on the line iron tower. The clamp arm of the clamp arm screw is clamped on the cross arm of the iron tower, and the other end is connected to the wire of the insulator string through a pull plate or a pull rod. At the end, the gravity of the wire is applied to the lead screw by the rocker arm to control the tension to replace the insulator string. Therefore, the safety performance of the clamp arm lead screw must be reliable. According to regulations, the arm screw should be subjected to a static load test, but due to the particularity of the shape of the arm, the use of angle steel connection will cause the non-linear stress angle steel to break, so that the arm screw cannot be directly installed on...
