Swimming Cable Harness Multipurpose Rigid Splice

Abstract

The invention discloses a multipurpose rigid joint for a moving cable harness. The multipurpose rigid joint comprises a steel bush in which an exhaust hole is formed, wherein the outer circumference at the rear end of the steel bush is radially and symmetrically fixed with a fixed plate, a rigid joint fixing hole for fixing a hydraulic pipeline is formed in the fixed plate, and a grasper fixed button is fixed at an inner bore of the steel bush near the rear end; the grasper fixed button is used for fixing a cable grasper, the rear end of the outer wall of the steel bush is fixed with the rigid joint fixing weld assembly, and the rigid joint fixing weld assembly is used for fixing the entire rigid joint on a headframe or a control console. According to the multipurpose rigid joint provided by the invention has the following beneficial effects: 1, an inner structure is reasonable and compact in structure and multi-function can be realized; 2, the exhaust hole is formed to prevent the insulation reduction because the cable is affected with damp; 3, the serialization can be realized in accordance with the type of the cables; and 4, the cable and a hydraulic pipeline can be integrally used, so as to be convenient for installation and dismantling.

Description

technical field

[0001] The invention relates to a multi-purpose rigid joint, in particular to a multi-purpose rigid joint used for a top drive traveling cable of an oil production platform. Background technique

[0002] The top drive traveling cable is one of the necessary electrical accessories for the top drive device. The traveling cable is composed of multiple sets of cable harnesses and is connected between the second floor of the derrick and the top drive control cabinet. In order to facilitate the fixation at the derrick end and the control cabinet end, rigid joints are required. The currently used joints do not fully consider the characteristics of the cable, and the phenomena of mutual interference of cable movement signals and low cable insulation often occur, which affect the normal operation of the top drive cable. Contents of the invention

[0003] The object of the present invention is to overcome the disadvantages of the prior art, and provide a multi-purpo...
