Description

Technical Field

[0001] The utility model relates to the technical field of cable trailers, in particular to a cable trailer with double drums. Background Art

[0002] Cable trailers are used in power sector operations. They are suitable for overhead power and communication line projects and are convenient for cable transportation and deployment. They mainly include dual-stable cable trailers, hydraulic steel wire trailers, lightweight cable trailers, and hydraulic folding cable trailers.

[0003] According to the description of a cable trailer disclosed in the patent website (authorization announcement number: CN 212047096 U), "the utility model discloses a cable trailer, whose structure includes an oblique support rod, a fixed bracket, a cable reel, a dust cover, a roller, a control block, a fixed carrier, and a reel limit block. The utility model discloses a cable trailer. By pulling the fixed carrier to rotate the roller on the cable reel, the fixed carrier can pull and displace the cable on the cable reel. When pulling, in order to prevent the cable reel from rotating, the rotating block on the reel limit block can be rotated to drive the air push plate to move vertically downward, thereby pushing the gas in the sliding groove, so that the limit pin rod on the sliding groove of the connecting ring is pushed, thereby being embedded in the card tooth on the reel connecting shaft ring, and limiting the rotation of the reel limit block. By improving the structure of the equipment, the equipment can better lock the reel tube on it after the cable is installed, so as to prevent the reel tube from rotating during transportation, so that the cable on it falls off, which is not conducive to the transportation of the cable."

[0004] In view of the above description, the applicant believes that there are the following problems:

[0005] During use, the utility model can lower the air push plate and the limit pin by rotating the rotating block, so that the limit pin can be lowered and inserted into the inner side of the latch tooth to prevent the cable reel from rotating. However, in actual use, when the screw drives the air push plate to descend, due to the gap inside the threaded groove, air leakage will occur inside the fixed valve block after repeated use, which will cause the limit pin to be unable to be normally inserted into the latch tooth, so that the reel of the cable trailer will still rotate, affecting transportation. Therefore, it is necessary to improve a cable trailer with a double reel to solve the above problem. Utility Model Content
