he function of high mast light pole
The function of the high mast light pole is mainly reflected in the lamp pole, mainly because the lamp pole can sit the lifting work, that high mast light pole mainly depends on what to do the lifting work. Tall pole lamp also is a kind of illuminative device, lamp head modelling is to need specific and decide according to user requirement, surroundings, illume commonly. The rod body is usually a cylindrical one-body structure, made of steel plate. The high-pole lamp indicates that in the rectangular inner cavity at the bottom of the elevating high mast light pole, an electric motor and other lifting systems are installed in addition to the electrical control system.
The electrical control system is installed inside the lamp pole to avoid the failure of lifting movement caused by bad outdoor environment. Electrical control system is equipped with various circuit overload protection devices. Copper – based silver plating is widely used in the electrical conductors of the system to ensure good contact of electrical connections.
Working principle of high mast light pole
The lifting and lowering system of lifting high mast light pole is driven by motor, (electromagnetic braking) worm reducer, safety coupling, main steel wire rope, auxiliary steel wire rope, rope splitter and movable pulley. Worm gear reducer has strong self-locking ability, compact transmission and large transmission ratio. In order to reduce the gear ratio of worm gear and worm and reduce the rising torque, a special set of movable pulley is added, which makes the lifting speed of the lamp plate less than 0.2 m/s.
The main wire rope is connected with the auxiliary wire rope of the lamp disc by the rope splitter, which can avoid the winding of the secondary wire due to the stretching of the main wire. The main and secondary steel wire ropes adopt high strength corrosion resistance 6*19 type non-rotating galvanized steel wire rope.
The lifting pulley block adopts A3 steel bracket, stainless steel shaft and copper pulley treated with hot galvanization to ensure the flexible operation without corrosion under normal atmospheric conditions. All kinds of fasteners, gaskets, fasteners and other parts are also hot – plated zinc or non – embroidered steel. There are 6 sets of guide pulley block and more than 3 sets of braking devices on the lamp disc. The guide wheel with a distribution of 120 degrees in the process of lifting or descending of the lamp plate rolls along the surface of the lamp pole to ensure that the lamp disc does not oscillate.
The working part of the guide wheel of the lamp disc is in contact with the surface of the lamp pole. In order to fully guarantee the automatic stop when the lamp disc reaches the limit position, the limit switch with reliable performance is installed when the lamp disc moves up and down. The lifting and lowering of the lamp tray is realized by changing the rotation direction of the motor. For security against theft, the rectangular cavity is equipped with a sealed door, which is equipped with a special lock.
