Description

Technical Field

[0001] The utility model relates to the technical field of rail transit cable installation, in particular to a cable joint bracket device. Background Art

[0002] Cables are an essential structural part of rail transit operation. Cable laying is generally fixed in position using support structures that are arranged at intervals along the longitudinal direction of the cables. Existing support structures are generally set on channel steel supports fixed on the concrete wall of the channel or the ground.

[0003] However, it was found during construction that due to the heavy weight of rail transit cables, the connection parts between the support structure and the channel steel support, and between the channel steel support and the wall or the ground are subject to large shear forces, and are prone to loosening due to vibration under the influence of long-term external train vibrations. There is a risk of partial cable detachment or slippage. At the same time, due to the large outer diameter of the cable, it is not easy to bend. The existing support structure and channel steel support are both integral structures with a long length. On the one hand, it is impossible to fine-tune the support height of the cable at a local position, and it needs to be prepared separately according to the support height, which increases production costs and affects the construction period. On the other hand, for construction entering areas with narrow passages, the long channel steel supports are not easy to be manually transported into the passage for installation. If they are cut short and moved in, additional welding operations are required, and hot work needs to be carried out in the narrow construction space. Generators are also required to accompany the construction, which greatly increases machinery costs. Utility Model Content
