Problems solved by technology

[0002] In the prior art, when conducting mechanical tests on DC submarine cables, the main way to fix the fixture is to use lead casting. The specific method is to extend one end of the DC submarine cable into the lead filling mold, and then pour the lead melted at high temperature into the mold. ; After the lead is solidified and cooled, the mold is opened, and the lead and the end of the submarine cable are formed into one; For example, the long man-hours required for manufacturing will affect the test efficiency; many tools are required for fixture installation; the installation steps are cumbersome and costly; And prolonged contact can cause poisoning

Abstract

The invention discloses a clamp for fixing a direct current submarine cable. The clamp comprises a clamp body which is provided with a through taper hole, a taper sandwich core which has conicity the same as that of the taper hole, is provided with an axial through hole and can be connected to the clamp body by being inserted into the taper hole, and a retaining member which is fixedly connected to an armor layer on the surface of a submarine cable and presses against the sandwich core. Through cooperation between the taper sandwich core and the clamp body with the through taper hole, the clamp realizes stretching and clamping of the submarine cable simultaneously. Through arrangement of a double-head screw and left- and right-handed screwed holes, screw rotation is transformed into screw linear displacement so that submarine cable tensioning and loosening can be adjusted optionally. The clamp has a simple structure and is convenient for use.

Description

technical field [0001] The invention relates to a clamp. Background technique [0002] In the prior art, when conducting mechanical tests on DC submarine cables, the main way to fix the fixture is to use lead casting. The specific method is to extend one end of the DC submarine cable into the lead filling mold, and then pour the lead melted at high temperature into the mold. ; After the lead is solidified and cooled, the mold is opened, and the lead and the end of the submarine cable are formed into one; For example, the long man-hours required for manufacturing will affect the test efficiency; many tools are required for fixture installation; the installation steps are cumbersome and costly; And prolonged contact can also cause personnel poisoning. Contents of the invention [0003] In order to overcome the deficiencies of the prior art, the present invention provides a clamp that can be used for fixing a direct current submarine cable, which can clamp the submarine cab...
