Height Lamp Lifting Principle
- Aug 01, 2018 -

High pole lamp is to point to the new lighting device of steel conical lamp pole and high power combination lamp holder of 15 meters above commonly. It is made up of lamp holder, internal lamp electric, rod body and foundation. Lamp head can be shaped according to user requirements, surrounding environment, lighting needs specific and decided; The internal lamps are mainly composed of floodlights and floodlights. The light source is NG400 high pressure sodium lamp with a lighting radius of 60 meters. The bar body is usually a pyramid - shaped single - body structure, made of steel plate, with a height of 15-40 meters, mostly two to three sections.

Height Lamp Lifting Principle

In the rectangular inner cavity at the bottom of the lifting pole lamp, besides installing electric control system, electric motor and other lifting system are also installed. 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. The lifting and lowering system of lifting high-pole lamp 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.
