Since the introduction of intelligent building technology into my country in the early 1990s, after more than 20 years of development, intelligent building technology has been greatly promoted and applied in our country. At present, all kinds of new buildings or renovated buildings cannot be involved in building intelligent engineering to a certain extent. Among them, the integrated wiring system is the infrastructure of the building intelligent system, and the bridge and various pipelines are the skeletons that carry various cables in the integrated wiring system. In most cases, the cables laid in the bridge frame are almost the backbone cables in the integrated wiring system. Therefore, the quality of the threading construction in the bridge frame often determines the quality of the entire building intelligent system.

At present, the threading in the bridge frame is mainly done by manpower, that is, a worker is arranged every few meters, and the upstream thread is first threaded downstream. If the number of cables laid in the bridge frame is relatively large, in order to improve efficiency, workers often tie many cables laid in the same direction together during construction and pass them through at the same time. Therefore, this construction method is not only very inefficient, but also the construction quality cannot be guaranteed. Invention of this bridge frame threading traction device is in order to solve the above problems.

detailed description

Below with reference to accompanying drawing, through the description of embodiment, to the specific embodiment of the present utility model such as the shape of each member involved, structure, mutual position and connection relationship between each part, the effect of each part and working principle etc. Further details.

As shown in Figure 1, it is a schematic diagram of the structure of the bridge threading traction device, including a driving fastening device 2 and a drag hook 8. The driving fastening device 2 is arranged in the bridge body 1, and the driving fastening device 2 is against the inner wall of the bridge body 1. Operation, the drag hook 8 is hung on the bottom of the driving fastening device 2, the driving fastening device 2 includes a driving motor 21, a driving wheel 23 and a transmission shaft 22, the driving motor 21 is connected with the transmission shaft 22, and the transmission shaft 22 is connected with the driving wheel 23 , the drive wheel 23 is against the inner wall of the bridge body 1 top, the drive motor 21 is powered by the rechargeable battery 24, and the drive motor 21 drives the entire drive fastening device 2 to move in the bridge body 1.
