A screw-fastened cable crossing coupling

Abstract

The utility model embodiment discloses a screw-fastened cable crossing coupling in the field of cable coupling technology. When installing the cable, the cable is placed in the groove cavity of the cable placement groove, and the first arc-shaped clamping block cooperates with the second arc-shaped clamping block to tighten the first limit ring and the second limit ring, and synchronously drives the first and second grooves to squeeze the cable, so that the cable moves to the bottom of the groove cavity of the cable placement groove. When the cable moves to the bottom of the groove cavity of the cable placement groove, the clamping block is pushed synchronously, so that the clamping block presses down the reset component, so that the V-shaped spring piece undergoes elastic deformation, and the strip-shaped protrusion synchronously slides from the groove cavity of the arc-shaped groove 2 to the groove cavity of the arc-shaped groove 1, thereby driving the front and rear sides of the upper end of the clamping block to approach the cable to clamp the cable. Through the arrangement of the first rubber anti-skid pad and the second rubber anti-skid pad, the cable is relatively stable, not easily pulled and damaged when the cable is lowered into the well, and the cable is not easily scratched when installed.

Description

Technical Field

[0001] The utility model embodiment relates to the technical field of cable couplings, and in particular to a screw-fastened cable crossing coupling. Background Art

[0002] At present, some water injection wells in oil fields use hydraulically controlled injection technology. The hydraulically controlled pipeline is needed to adjust the flow rate, and the cable is needed to transmit data. Both need to be lowered into the well at the same time as the pipe string. Due to the small inner diameter of the sand control section in the well, during the lowering of the pipeline and cable, it may collide at the oil pipe coupling, causing damage or scratches to the pipeline and cable, and thus, the reliability and safety of the pipeline and cable during the lowering process cannot be guaranteed.

[0003] Cable couplings are used to protect cables, including couplings for connecting oil pipes and other components installed on the couplings. When conventional cables are installed on cable couplings, the cables are bent toward the coupling direction and inserted into the coupling groove. At the same time, the cables are pushed inward to lock them. This can easily cause squeezing of the cables, leading to the risk of friction, scratches, and bumps. The cable's own weight and the natural bending or external traction caused by the coupling being connected to the oil pipe and lowered into the well can easily cause the cable to deviate up and down, resulting in cable pulling damage. Utility Model Content

[0004] To this end, an embodiment of the utility model provides a screw-fastened cable crossing coupling to solve the problems in the prior art that the cable is easily damaged by pulling when lowered into the well and the cable is easily scratched by friction during installation.

[0010] The second fastening assembly comprises a clamping block, a first rubber anti-skid pad and a second rubber anti-skid pad for protecting and preventing the cable from slipping are installed in the middle of the clamping block, and a reset assembly is installed at the lower end of the clamping block.
