The structure and advantages of the lifting high pole lamp
High pole lights can generally be divided into lifting type and non-lifting type. The height of the main lifting pole is generally above 18 meters, and the electric lifting operation is convenient. LED street lamp manufacturers are a solid-state cold light source, which has the characteristics of environmental protection, no pollution, low power consumption, high light efficiency, and long life. Therefore, LED street lamps will become the best choice for energy-saving transformation of road lighting. LED street light is a kind of high-efficiency solid-state light source formed by semiconductor PN junction that can emit light with weak electric energy. Under a certain forward bias voltage and injection current, the holes injected into the P zone and the electrons injected into the N zone are in After being diffused to the active area, photons are emitted through radiation recombination, which directly converts electrical energy into light energy. After the lamp panel is raised to the working position, the valve clack can be automatically removed, the groove is hung, and the wire rope is removed.

Under a certain forward bias voltage and injection current, the holes injected into the P zone and the electrons injected into the N zone are in After being diffused to the active area, photons are emitted through radiation recombination, which directly converts electrical energy into light energy. The utility model adopts manual and electric lifting control methods, so that the light board can be safely and reliably lowered to 2.5 meters from the ground, which is convenient for maintenance. The length of the manual remote control device is 10 meters, and the operator can control the lifting of the light board at 5 meters, thus ensuring the personal safety of the operator. The hoisting high pole lamp is also equipped with a spare cable. When the light board is lowered to the lowest position, insert one end of the cable into the socket of the electrical control system and the other end into the junction box on the light board, so that the light board can be directly supplied and the lamps can be overhauled.
The sealing level of all lamps of the lift-type high pole lamp is IP65 international standard to prevent dust and rain from intruding, and to ensure the service life of the lamp. Aluminum alloy plates and non-embroidered steel with good corrosion resistance are commonly used materials for lamps. In the rectangular cavity at the bottom of the lifting high pole lamp, in addition to the electric control system, a lifting system such as a motor is also installed. The electrical control system is installed in the light pole to avoid the failure of the lifting movement due to the harsh outdoor environment. The electrical control system is equipped with various loop overload protection devices. Copper-based silver plating is widely used as the conductor of the circuit in the system to ensure good electrical connection.
The lifting system of the lifting high pole lamp is driven by the electric motor, (electromagnetic brake type) worm gear reducer, safety coupler, main wire rope, auxiliary wire rope, shunt and mobile pulley block. Light dish lift. The worm gear reducer has strong self-locking ability, compact transmission and large transmission ratio. In order to reduce the speed ratio of the worm wheel and the worm wheel and reduce the rising torque, a set of moving pulleys was added to make the speed of the lamp panel less than 0.2 meters. /second.
The main steel wire rope is connected with the auxiliary steel wire rope of the lamp panel through the rope distributor. Due to the stretching of the main steel wire, the entanglement of the auxiliary steel wire can be avoided. The main and auxiliary steel wire ropes adopt high-strength corrosion-resistant 6*19 type non-rotating galvanized steel wire rope.
The lifting pulley block adopts A3 steel bracket, stainless steel shaft and copper pulley for hot-dip galvanizing to ensure flexible operation under normal atmospheric conditions. Various fasteners, collars and other parts are also hot-dip galvanized or not embroidered. The lamp panel is provided with six groups of guide wheel blocks and three or more braking devices. The guide wheels distributed at 120 degrees roll along the surface of the lamp pole during the lifting process of the lamp panel to ensure that the lamp panel does not swing. The surface of the working part of the lamp panel guide wheel and the surface of the lamp post are treated by rubber hot pressing. In order to fully ensure the automatic stop of the light board at the extreme position, the light board is lifted, and the downward movement is provided with a reliable limit switch and an over-travel protection.
The lifting of the high pole lamp panel is realized by changing the rotation direction of the motor. In order to prevent theft, a sealed door is arranged in the rectangular cavity and a special door lock is provided.
The electric lifting system consists of a motor, a winding machine, three sets of hot-dip galvanized steel cables and cables.
