[0002] Cable trays are structural devices used to support and protect cables and wires. They are used in building electrical installations, industrial plant wiring, etc. Cable trays have advantages such as high load-bearing capacity and good fire resistance, and are suitable for various industrial and civil buildings.

[0003] When installing cable trays, conventional hoisting brackets are installed on the top of the wall using expansion bolts and supported by a bottom support plate. However, the cable trays are only placed on the bottom support plate, which may cause misalignment during installation, thus increasing the difficulty of assembling the cable trays. To address this, we propose a new type of cable tray for building electrical construction to overcome the shortcomings of existing technologies. Summary of the Invention

A support plate is fastened to the bottom of the expansion screws. The top of the support plate contacts the bottom of the cable tray body. Vertical plates are fixedly connected to the front and rear positions of the inner cavity of the support plate. A bearing seat is embedded and fixedly connected to the inner cavity of the vertical plate. An internal threaded cylinder is rotatably connected to the inner surface of the bearing seat. A threaded rod is threadedly connected to the inner surface of the internal threaded cylinder. A sliding plate is fixedly connected to one side of the threaded rod. A connecting plate is fixedly connected to the top of the sliding plate. A vertical limiting plate is fixedly connected to the top of the connecting plate. Through grooves for sliding and matching the connecting plate are opened on both sides of the top of the support plate. A sliding groove is opened on one side of the inner cavity of the support plate. The inner surface of the sliding groove is slidably connected to the sliding plate. The opposite side of the vertical limiting plate is fastened and fitted to the cable tray body.

[0006] Preferably, the top of the vertical limiting plate is fixedly connected to a threaded post, the outer surface of the threaded post is fitted with an upper limit plate, and the outer surface of the threaded post is threaded with a fastening nut, which is located on the top end face of the upper limit plate.

[0007] Preferably, the top of the cable tray body is provided with a cover plate, and grooves are provided on both sides of the inner cavity of the cover plate, with the top end face of the cable tray body located on the inner surface of the grooves.
