Description

Technical Field

[0001] The utility model relates to construction tools for power equipment, in particular to a device for assisting in installing a wire duct bracket on a railing of a railway viaduct. Background Art

[0002] In railway construction, to ensure the stability and reliability of power supply facilities along the line and the absolute safety of train traction power supply, the laying of cables is particularly important. Taking the high-speed railway viaduct as an example, steel railings are often provided on both sides of these bridges. By cleverly utilizing the spatial layout on both sides, wire duct brackets are fixed on each railing column. These brackets lay a solid foundation for the subsequent installation of wire ducts. Subsequently, the wire ducts are steadily installed on the brackets, forming a passage that is both convenient for maintenance and conducive to cable laying, achieving the efficiency and beauty of cable laying, effectively improving the convenience and safety of cable laying, and demonstrating the wisdom and ingenuity in railway construction.

[0003] In the existing construction of wire duct brackets and wire ducts, workers need to fix and install each wire duct bracket on the railing column one by one, and at the same time, it is necessary to ensure that each wire duct bracket is at the same height. In view of the influence of the conditions of the railway viaduct, specifically, the wire duct brackets are positioned according to the relative height from the wire duct bracket to the top of the railing. For this reason, workers must conduct repeated measurements when installing each wire duct bracket, and the number of wire duct brackets to be installed is large. As a result, the workload of installing wire duct brackets is extremely huge, not only the work efficiency is low, but also the installation accuracy of the wire duct brackets cannot be effectively guaranteed, and even situations such as inclination and deviation may occur, seriously affecting the construction quality. Summary of the Utility Model

[0006] Further, the height adjustment mechanism includes a cross bar arranged horizontally, a screw rod and a nut that are screwed together; the cross bar is installed on the top of the main rod, a vertical through hole is opened on the cross bar, one end of the screw rod passes through the through hole and is fixedly connected to the top plate, and nuts are screwed on the top surface and the bottom surface of the screw rod respectively.

[0007] Alternatively, the height adjustment mechanism includes a positioning sleeve sleeved on the main rod and movable along the main rod. The top plate is fixedly connected to the positioning sleeve. The positioning sleeve is provided with a threaded hole, and a locking bolt is screwed onto the threaded hole. The end of the locking bolt abuts against the main rod.
