High pole light: generally refers to a new type of lighting device composed of a steel column light pole above 15 meters and a high-power combined light frame. It is composed of lamp holder, internal lamp electrical, rod body and basic parts. The shape of the lamp head can be determined according to the user's requirements, the surrounding environment, and the lighting needs; the internal lamps are mostly composed of floodlights and floodlights.

1. The light pole is an octagonal or twelve-pointed cone-shaped pole body, which is formed by cutting, bending and automatic welding of high-strength high-quality steel plates. The general height is 2 5, 3 0, 3 5 and other specifications. The maximum wind resistance design can be Up to 60 m/s, each specification is composed of 3 to 4 joints. Equipped with a flanged steel chassis with a diameter of 1m to 1.2m and a thickness of 30mm to 40mm.

2. Functionality is mainly based on frame structure, and there are also decoration-based materials such as steel pipes and steel pipes. Light poles and lamp panels are treated with hot-dip galvanizing.

3. The electric lifting system is composed of an electric motor, hoist, three sets of hot-dip galvanized control steel wire ropes and cables. The light pole is installed in the body, and the lifting speed is 3 to 5 meters per minute.

4. The guide and unloading system is composed of guide wheels and guide arms to ensure that the lamp panel will not move laterally during the lifting process, and when the lamp panel rises to the right position, the lamp panel can be automatically dropped and locked by the hook.
5. The lighting electrical system is equipped with 6-24 400w-1000w metal halide (white light), floodlight and floodlight lamps. The computer time controller can automatically control the time of switching lights and partial lighting or full lighting. illumination.
6. Lightning protection system: a 1.5-meter-long lightning rod is installed on the top of the lamp, and a 1-meter-long grounding wire is installed on the underground foundation and welded with underground bolts.

In the rectangular inner cavity at the bottom of the lifting high pole lamp, in addition to the electrical control system, the lifting system such as the motor is also installed. The electrical control system is installed inside the light pole, which can avoid the failure of the lifting movement caused by the harsh outdoor environment. Various circuit overload protection devices are installed in the electrical control system. The conductors of the circuits in the system are widely plated with copper-based silver to ensure good contact of electrical connections. The lifting system of the lifting high pole lamp is driven by the electric motor, (electromagnetic brake type) worm gear reducer, safety coupling, main wire rope, auxiliary wire rope, rope divider and movable pulley block to drive the lamp panel up and down.

The worm gear reducer has strong self-locking ability, compact transmission, and a large transmission ratio. In order to reduce the gear ratio of the worm gear and the worm and reduce the rising torque, a set of moving pulleys is specially added to make the lifting speed of the lamp panel less than 0.2 m/s . The main steel wire rope is connected with the auxiliary steel wire rope of the lamp panel through the rope splitter, which can avoid the winding of the auxiliary steel wire due to the stretching of the main steel wire. The main and auxiliary steel wire ropes are all made of high-strength and corrosion-resistant 6*19 non-rotating galvanized steel wire ropes. The lifting pulley block is made of hot-dip galvanized A3 steel bracket, stainless steel shaft, and copper pulley to ensure that it will not rust and operate flexibly under normal atmospheric conditions.

Various fastener washers, collars and other parts are also made of hot-dip galvanized parts or stainless steel. There are 6 sets of guide pulleys and more than three sets of braking devices on the lamp panel. The guide wheels distributed at 120 degrees roll along the surface of the lamp pole during the lifting or lowering of the lamp panel to ensure that the lamp panel does not swing. The surface of the working part where the guide wheel of the lamp panel is in contact with the surface of the lamp pole adopts a rubber thermocompression bonding process. In order to fully ensure that the lamp panel will automatically stop when it reaches the limit position, reliable limit switches are installed for the rising and falling movements of the lamp panel, and over-travel protection is provided. The lifting of the lamp panel of the high pole lamp is realized by changing the rotation direction of the motor. For safety and anti-theft, the rectangular cavity is equipped with a sealed door, and a special door lock is installed on the sealed door
