Cable coil cable-releasing speed reduction mechanism for cable laying installation

Abstract

The invention relates to the technical field of cable installation and discloses a cable coil cable-releasing speed reduction mechanism for cable laying installation. The cable coil cable-releasing speed reduction mechanism comprises a base, the top of the base is fixedly connected with a first supporting column, the top of the first supporting column is movably connected with a first rotating shaft, and the outer side of the first rotating shaft is fixedly connected with a cable winding disc. According to the cable coil cable-releasing speed reduction mechanism for the cable laying installation, when a cable coil rotates too fast, this moment, a first metal ball contacts a second metal ball to make clamping connection heads be clamped at positions of position-limiting blocks, so that thespeed of a disc is reduced, and this moment, the speed of the first rotating shaft is reduced through a second rotating shaft, so that the effect of preventing the cable coil from rotating too fast isachieved; and the speed of the disc is reduced, this moment, the first metal ball is not in contact with the second metal ball, the clamping connection heads do not clamp the position-limiting blocksany longer, the speed of the disc is restored, circulation is performed for many times to reduce the speed of the cable coil, and the effect of preventing cable from being pulled and destroyed in thecable coil speed reduction process is achieved.

Description

technical field [0001] The invention relates to the technical field of cable installation, in particular to a cable reel pay-off deceleration mechanism for cable laying and installation. Background technique [0002] In the process of cable laying and installation, due to the relatively large quality of the cable, a large number of people are generally required to pull the cable during the laying and installation process. During the process, the cable will be released faster and faster, and the cable reel will rotate faster and faster, and the cable reel does not have an effective braking function. At this time, safety accidents are likely to occur. How to effectively control the cable rotation speed, Preventing the cable drum from rotating too fast has become an important issue, so we propose a cable drum pay-off deceleration mechanism for cable laying and installation.

Problems solved by technology

[0004] Aiming at the deficiencies of the prior art, the present invention provides a cable reel pay-off deceleration mechanism for cable laying and installation, which has the advantages of effectively controlling the cable rotation speed and preventing the cable reel from rotating too fast, and solves the problem of If you encounter a slope section, when the cable is lowered from the upper end of the slope, the cable will be released faster and faster during the process of pulling the cable due to a large number of people, and the cable drum will rotate faster and faster, and the cable drum does not have effective The braking function is prone to safety accidents at this time
