It is understood from the signal light pole manufacturer that the basic structure of the signal light pole is composed of road traffic signal poles, and sign poles should be composed of vertical poles, connecting flanges, modeling arms, mounting flanges and embedded steel structures. According to the structure, signal light poles are divided into octagonal signal light poles, cylindrical signal light poles, and conical signal light poles. According to the structure, it can be divided into single cantilever signal light pole, double cantilever signal light pole, frame signal light pole, and integrated signal light pole.
The vertical pole or the horizontal support arm adopts straight seam steel pipe or seamless steel tube; the connection end of the vertical pole and the horizontal support arm adopts the same steel pipe as that of the horizontal arm, and is protected by a welded reinforcement plate; the vertical pole and the foundation are connected by flanges and embedded bolts , Welding reinforcement plate protection; the connection mode of the horizontal support arm and the end of the vertical rod adopts flange connection, and the welding reinforcement plate protection is carried out.
All welding seams of the pole and its main components should meet the standard requirements, the surface should be smooth and smooth, the welding should be smooth, smooth, firm and reliable, and free of defects such as porosity, welding slag, false welding and missing welding.
The pole and its main components have lightning protection function. The non-charged 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 should be equipped with a reliable grounding device, and its grounding resistance should be ≤10 ohms.
Signal light pole handling method: the wire rope behind the traffic sign pole must jump tightly and cannot be loosened. At this time, remember to disconnect the power supply or turn off the main power supply and no longer operate. According to the height of the light pole, find a high-altitude crane with two hooks. , Prepare a hanging basket (pay attention to the safety strength) and then prepare a broken wire rope, remember that there is no break and a whole rope is advisable, pass through the two lanes from the bottom of the hanging basket and then pass through the hanging basket* to hang to the hook, pay attention to the hook There must be safety insurance against falling off. Prepare two walkie-talkies. Please keep the call smoothly on the frequency before going up to the sky. After the crane operator communicates with the lamp panel maintenance personnel, start to work. Note that the high-pole lamp maintenance personnel must have electrician knowledge and understand the principle of lifting. The crane operation should have relevant qualifications. After the hanging basket rises to a predetermined height, the aerial worker connects the other hook of the crane to the lamp panel with a steel wire rope. After rising slightly, he holds the lamp panel with his hand and tilts it upward, and the other person uses a wrench to loosen it. After the stuck hook, put the tools away, the crane can hoist the hanging basket to one side without affecting the normal lifting. At this time, the operator on the ground began to lower the lamp panel, until it descended to the ground, the staff on the hanging basket came to the top of the pole again, took off the three hooks and returned to the ground, and then polished it smoothly with a grinder and buttered it. And replace the connecting bolt (galvanized) and then install it on the top of the pole again, and turn the three hooks several times by hand. Until safe lubrication.
