The basic structure of traffic signal light pole is composed of road traffic signal light pole, and the signal light pole is composed of vertical pole, connecting flange, modeling arm, mounting flange and pre embedded steel structure. The signal lamp pole is divided into octagonal signal lamp pole, cylindrical signal lamp pole and conical signal lamp pole according to its structure. According to the structure, it can be divided into single cantilever signal pole, double cantilever signal pole, frame cantilever signal pole and integrated cantilever signal pole.
The vertical rod or horizontal support arm adopts straight seam steel pipe or seamless steel pipe. The connecting end of the vertical rod and the horizontal support arm is made of the same steel pipe as the cross arm, and is protected by the welded reinforcing plate. The vertical pole and the foundation are connected by flanges and embedded bolts, and are protected by welding reinforcing plates; The connection between the cross arm and the end of the vertical pole is flanged and protected by welding reinforcing plates.
All welds of the vertical pole and its main components shall meet the standard requirements, and the surface shall be flat and smooth. The welding shall be flat, smooth, firm and reliable, and free of defects such as pores, welding slag and false welding. The pole and its main components have lightning protection function. The uncharged metal of the lamp forms a whole and is connected to the grounding wire through the grounding bolt on the shell. The pole and its main components shall be equipped with reliable grounding device, and the grounding resistance shall be ≤ 10 Ω.
Treatment method for traffic signal pole: the steel wire rope must jump tightly behind the traffic sign pole and cannot be loosened. At this time, remember to disconnect the power supply or turn off the main power supply, and then stop the operation. According to the height of the light pole, find the overhead crane with two hooks, prepare a hanging basket (pay attention to the safety strength), and then prepare a broken steel wire rope. Remember that the entire rope is not broken, pass through two channels from the bottom of the hanging basket, and then pass through the hanger basket. Hang the hook on the hook, and pay attention to that the hook must have a safety insurance against falling. Prepare two interphones and turn up the voice. Please keep a good call frequency. After the crane operator contacts the light panel maintenance personnel, start work. Please note that the maintenance personnel of the high pole lamp must have electrician knowledge and understand the lifting principle. Crane operation shall be qualified.
After the basket is raised to a predetermined height, the high-altitude operator uses wire rope to connect another hook of the crane to the light plate. After lifting slightly, he holds the lamp panel with his hand and inclines it upwards, while others use a wrench to loosen it. After the hook is stuck, put the tool away, and the crane will lift the basket to one side without affecting the normal lifting. At this time, the operator on the ground began to put down the light plate until it fell to the ground. The staff on the basket came to the top of the pole again, moved the three hooks back to the ground, and then polished them. Use a grinder to coat it with butter smoothly, then reinstall the connecting bolt (galvanized), and then reinstall it on the top of the rod, and turn the three hooks several times by hand until it is lubricated safely.
The above is the structure and characteristics of the traffic signal pole. At the same time, I also introduced the processing method of signal lamp pole. I am sure you will get something after reading these contents.
