Description

Technical Field

[0001] The utility model relates to the technical field of pipeline corridor cables, in particular to an adjustable pulley device for pipeline corridor cable threading. Background Art

[0002] Cable corridors are usually constructed in the form of shallow buried trenches, with openable covers on the corridors. However, the internal space cannot meet the normal traffic requirements of personnel and can only be used to accommodate power cables and communication cables. When installing the cables in the corridor, a bracket will be installed inside the corridor, and the cables will be limited by a clamping device. In order to facilitate the adjustment of the cable installation position, a pulley is installed on the outside of the clamping device, and the clamping device is driven by the pulley to move on the bracket, and then the cable installation position is adjusted. During the installation of the corridor cable bracket, the positions of multiple sets of clamping devices need to be adjusted. During the adjustment, the spacing between two adjacent sets of clamping devices is prone to unevenness, which will affect the arrangement effect of the clamping devices on the bracket. When the distance between the two sets of clamping devices is too close, the cables will be misaligned when arranged, affecting the cable transmission. For this reason, we propose an adjustable pulley device for corridor cable threading. Utility Model Content
