A cable fixing bracket with automatic limit straightening

Abstract

The invention provides a cable fixing bracket capable of automatically limiting and straightening a cable. First insulating columns and corresponding second insulating columns are installed rotationally in a crossing manner through a first rotating shaft; a mounting plate is mounted at the outer periphery of the first rotating shaft; clamps are mounted on the mounting plate; first sliding slots are formed in the first insulating columns; connecting shafts are connected into the first sliding slots through first sliding plates; a first mounting seat is mounted on the connecting shafts; a secondmounting seat is mounted in the first sliding slots through the first sliding plates and the connecting shafts; one side of the first mounting seat and one side of the second mounting seat, which areopposite to each other, are provided with mounting shafts; the mounting shafts are provided with limiting rolling wheels through third rotation shafts; and limiting plates which are symmetrically distributed with respect to the center of the limiting rolling wheel are arranged at the outer periphery of the limiting rolling wheel. According to the cable fixing bracket of the invention, the limiting and fixing of a three-phase cable are realized through the clamps mounted on the mounting plate, and therefore, the weight of the cable can be supported, the deformation of a pipe sleeve belt can beprevented; and the cable can be limited and straightened through the limiting rolling wheels, and therefore, the deformation of the pipe sleeve caused by the bending of the cable can be avoided.

Description

technical field [0001] The invention relates to the field of cable fixing devices, in particular to a cable fixing bracket with automatic limit straightening. Background technique [0002] When the three-phase cables are lapped, it is necessary to check the phases, and it is necessary to apply external force to twist the cables to fix each phase terminal separately. After installation, the transverse torsional stress will be gradually released and transmitted to the bushing. The electric power of the short-circuit current will also be transmitted to the bushing during operation, which will cause a fault caused by the leakage of the air chamber of the ring main unit, resulting in a huge electrical accident. However, the currently used cable fixing bracket cannot straighten the cable while fixing the cable, which makes the cable easy to bend and generates torsion, making cable installation difficult, and easily causing damage to the cable during the installation process.

The electric power of the short-circuit current will also be transmitted to the bushing during operation, which will cause the failure caused by the leakage of the air chamber of the ring main unit, resulting in a huge electrical accident

However, the cable fixing brackets actually used at present cannot straighten the cables while fixing the cables, which makes the cables easy to bend and generate torsion, which makes the installation of the cables difficult, and it is easy to cause damage to the cables during the installation process.
