Description

Technical Field

[0001] The utility model relates to the technical field of cable crossing couplings, in particular to a rubber block clamping type spring clip cable crossing coupling. Background Art

[0002] A cable crossing coupling is a device used to protect cables from damage when they pass through pipelines or other obstacles. Cable crossing couplings are used to connect downhole oil pipes and fix cables. They are usually made of metal and can be fixed on the inner and outer walls of the pipeline to ensure that the cable remains stable during the crossing process and avoid damage due to friction or impact.

[0003] For example, an integrated cable coupling protector provided in the Chinese patent application with application number 202120122078.6 includes: a coupling protector body, and several cable channels arranged on the coupling protector body; wherein the coupling protector body is a cylindrical structure; the coupling protector body is respectively provided with: an upper section oil pipe female thread and a lower section oil pipe female thread; the cable channel: is provided with several square grooves for the cable to pass through, and several special-shaped grooves are correspondingly connected to the several square grooves, a screw pressure cap is installed on the upper part of the special-shaped groove, a special-shaped fixing strip is placed in the middle part, and a step is provided at the lower part, the upper section oil pipe female thread is connected to the upper oil pipe, and the lower section oil pipe female thread is connected to the next oil pipe, and the special-shaped fixing strip fixes the cable by interference fit to prevent the cable from falling out of the coupling. The square groove of this technical solution matches the size of the cable. Therefore, there is no need to peel off the outer protective rubber of the cable during operation, and the square cable can pass through directly, which not only improves the operation efficiency, but also allows the addition of cable channels according to actual operation needs. Moreover, since the cable passes vertically from the inside of the coupling and the special-shaped fixing strip fixes the cable by interference fit to prevent the cable from escaping from the inside of the coupling, the cable can be protected during the process of being lowered into the pipe string. At the same time, the tubing coupling and the cable protector are integrated in design, with the upper tubing female thread connected to the previous tubing and the lower tubing female thread connected to the next tubing. Therefore, it has a simple structure, does not occupy the inner diameter space of the sand control section, and is applicable to a wider range of inner diameters.

[0004] However, the following problems still exist in this technical solution: the coupling protector body in this technical solution does not fix the cable, and the cable may exceed the maximum outer diameter due to bending of the cable itself or bending in the cable groove of the coupling protector, or the cable may be naturally bent or pulled by external force due to its own weight and the connection between the coupling and the oil pipe after being lowered into the well, which may easily cause the cable to be scratched or bumped by friction or cause the cable to deviate up and down, resulting in cable strain and other consequences. Replacing the damaged cable will consume unnecessary manpower and material resources, causing losses. Utility Model Content

[0005] To this end, an embodiment of the utility model provides a rubber block clamping type spring clip cable crossing coupling to solve the problem of the cable being deviated up and down due to the inability to fix the cable in the prior art.

[0006] In order to achieve the above-mentioned purpose, the embodiment of the utility model provides the following technical solutions: a cable coupling body, wherein the outer wall of the cable coupling body is provided with four cable grooves for placing cables, the middle part of each of the cable grooves is connected with two rubber block grooves distributed up and down, the two rubber block grooves are provided on the outer wall of the cable coupling body, a rubber block is inserted in each of the rubber block grooves, the cross-section of the rubber block is set to be U-shaped, an opening is provided on the side of the rubber block away from the center of the cable coupling body, the cable passes through the opening of the rubber block, and is clamped and fixed to the outer wall of the cable coupling body by the rubber block, the four cable grooves are evenly distributed in a ring shape outside the cable coupling body with the center of the cable coupling body as the center, the cross-section of the rubber block groove is U-shaped and matched with the rubber block, and is used for fixing and protecting the cable.

[0007] Furthermore, the outer walls at both ends of the cable coupling body are provided with retaining spring grooves for accommodating retaining springs, and the retaining springs can be made of spring steel. The two retaining spring grooves are connected with four cable grooves, and through openings for the cables to pass through are reserved at both ends of the retaining springs, and the through openings are connected with one of the cable grooves. The outer walls at both ends of the cable coupling body are clamped with retaining springs for clamping the cable coupling body to the outside of the oil pipe, and the two ends of the retaining springs are bent inwards and fit with the inner walls of the cable grooves for fixing and protecting the cables.

[0008] The utility model embodiment has the following advantages:

[0009] 1. Two rubber block grooves are set inside the cable groove on the cable coupling body. After the cable coupling body is connected with the oil pipe or tool, the rubber block is inserted into the opened rubber block groove, and then the cable is inserted into the rubber block. The rubber block is a U-shaped structure, which can lock the cable to prevent it from loosening. The cable coupling body and the rubber block cooperate with each other and are clamped between the cable and the cable coupling body. There is no problem of falling. The rubber block increases the friction between the contact surface with the cable, so that the cable is blocked from moving up and down, and will not cause displacement and fall out;

[0010] 2. The utility model inserts the cable into the through hole on the clamping spring and utilizes the elastic deformation of the clamping spring to clamp the cable, thereby achieving the fixation of the cable. The provision of the clamping spring enables the cable to be quickly installed and removed, and is easy to maintain. BRIEF DESCRIPTION OF THE DRAWINGS
