The high pole lamp generally refers to a new type of lighting device composed of a steel cone lamp pole above 15 meters and a high-power combined lamp structure. It is composed of lamp holder, internal lamp electrical, pole body and basic parts. The shape of the lamp holder can be determined according to user requirements, surrounding environment, and lighting needs. The internal lamps are mostly composed of floodlights and floodlights. The light source uses NG400 high-pressure sodium lamps with a lighting radius of 60 meters. The rod body is generally a pyramid-shaped single body structure, which is rolled out of steel plate, with a height of 15-40 meters, and most of it is composed of two to three sections.
Configuration:
1. The light pole is an octagonal, twelve-sided, and eighteen-sided pyramidal pole, which is cut, bent, and automatically welded to form high-strength high-quality steel plates. The general height is 25, 30, 35, 40 and other specifications, with the largest design The wind resistance can reach 60 meters per second, and each specification is composed of 3 to 4 plug-in sections. Equipped with flanged steel chassis, with a diameter of 1 meter to 1.2 meters and a thickness of 30 mm to 40 m m.
2. The functionality is mainly frame structure, and some are mainly decorated with steel pipes and steel pipes. Lamp poles and lamp panels are treated with hot-dip galvanizing.
3. The electric lifting system consists of an electric motor, a winch, three groups of hot-dip galvanized steel wire ropes and cables. The lamp pole is installed in the body, and the lifting speed is 3 to 5 meters per minute.
4. The guiding and unloading system is composed of guiding wheels and guiding arms to ensure that the lamp panel does not move laterally during the lifting process, and to ensure that the lamp panel can be automatically detached and locked by the hook when the lamp panel is raised in place.
5. The lighting electrical system is equipped with 6-2 4 4 0 0 w-1 0 0 0 w metal halide (white light),
Flood Light, flood light lamps, and the computer time controller can automatically control the switch light time and partial or full lighting.
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 to the underground bolt.
High pole lamp use place
The scope of use of high pole lights: city squares, stations, docks, freight yards, highways, stadiums, overpasses.
High pole lamp classification
Generally can be divided into lifting type and non-lifting type. The height of the lifting main pole is generally more than 18 meters, and the electric lifting operation is convenient. After the lamp panel is raised to the working position, it can automatically take off the panel, hang the ditch, and unload the wire rope.
The lift-type high-pole lamp is equipped with manual and electric lift control modes, so that the lamp panel can be safely and reliably lowered to 2.5 meters above the ground, which is convenient for maintenance work. The length of the lead wire of the manual remote control device is 10 meters, and the operator controls the lifting of the lamp panel at a distance of 5 meters, which can ensure the personal safety of the operator. The lift-type high pole lamp is also equipped with a spare cable. When the lamp panel is lowered to the lowest position, one end of the cable is inserted into the socket of the electrical control system, and the other end is inserted into the junction box on the lamp panel, so that the lamp panel can be directly supplied with power , Overhaul lamps.
The sealing grade of all lamps of the lift-type high pole lamp is IP65 international standard to prevent the intrusion of dust and rainwater and ensure the service life of the bulb. The materials of the lamps are generally made of aluminum alloy plates with good corrosion resistance and stainless steel.
The high-pole lights we usually talk about are actually very different according to their use. The classification and name of the high-pole lights vary according to different occasions. For example, those used in wharves are called high-pole lights on piers, and those used in squares are called high-pole lights in squares. Named there are port high-pole lights, airport high-pole lights, explosion-proof high-pole lights, stainless steel high-pole lights and so on. It is generally considered that the street light poles that exceed 15 meters are called high pole lights, ranging from 15 to 40 meters. The commonly used ones are 15 meters, 18 meters, 20 meters, 25 meters, and 30 meters. The five specifications are the most common. Others are generally the specific height required by the customer to design, this is what we often call the high pole lamp divided by height.
High pole lamp installation
High pole lamp preparation
1. Carefully count all components according to the loading and packing list.
2. Check whether the components are damaged, bent, twisted, and whether the zinc layer is damaged.
3. The signs on each section of the rod indicate the type, order number, and number of sections of the rod. The weight of the shaft is marked with a colored pen on the inside of the shaft. Check whether the delivery is correct and whether the crane lifting capacity is sufficient.
4. According to the maximum and minimum socket length provided on the drawing, make a mark on the rod for use when socketing.
High pole lamp assembly
1. Each splicing point provides a socket length, but due to the influence of manufacturing, installation errors and physical factors, there are changes in socket length, so the maximum socket length and the minimum socket length are provided.
2. In order to facilitate installation, it may be necessary to lubricate the mating surface. Be careful not to use lubricating oil to prevent leakage and contamination of the rod body, and soapy water can be used to lubricate the inner and outer surfaces of the sleeve.
3. When socketing, apply the necessary force at both ends to obtain a tight socket.
Lifting principle of high pole lamp
In the rectangular cavity at the bottom of the elevating high pole lamp, in addition to the electrical control system, a motor and other elevating systems are also installed. The electrical control system is installed inside the light pole to avoid the failure of the lifting movement caused by the harsh outdoor environment. There are various circuit overload protection devices in the electrical control system.
The conductors of the circuits in the system are widely plated with copper-based silver to ensure good electrical connections. The lifting system of the lifting high pole lamp drives the lifting of the lamp panel through components such as electric motor, (electromagnetic brake type) worm gear reducer, safety coupling, main wire rope, auxiliary wire rope, rope splitter and movable pulley group. The 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 set of movable 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 lamp panel auxiliary steel wire rope through the rope splitter, which can avoid the entanglement of the auxiliary steel wire due to the stretching of the main steel wire. The main and auxiliary steel wire ropes are made of high-strength, corrosion-resistant 6*19 non-rotating galvanized steel wire rope. The lifting pulleys are all made of A3 steel brackets, stainless steel shafts, and copper pulleys that have been hot-dip galvanized to ensure flexible operation without corrosion under normal atmospheric conditions.
Various fasteners, washers, clamp rings and other parts are also made of hot-dip galvanized parts or stainless steel. The lamp panel is equipped with 6 sets of guide pulleys and more than three sets of braking devices. The guide wheels distributed at 120 degrees roll along the surface of the lamp pole during the raising or lowering process 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 the rubber hot pressing process. In order to fully ensure that the lamp panel stops automatically 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 security and anti-theft, the rectangular cavity is equipped with a sealed door, and a special door lock is installed on the sealed door.
Important safety knowledge of high pole lights:
For users who have not been exposed to high-pole light products, check the production quality of a high-pole light and whether the installation process is reasonable. You can judge from the following points.
Since the height of
the high pole lights is between 18 meters and 35 meters, the lightning protection measures must be done well. Many of the high pole lights that we often see are only installed and used after hot-dip galvanizing. The main body of the light pole does not have a problem with electricity, but in recent years, considering the aesthetics of high-pole lights, a spraying process has been added to the surface of many sections, and silver and white are more common. At this time, you need to pay attention, and some High-pole lamp manufacturers have overlooked a problem, that is, the plastic powder itself is insulated. If the plastic powder is sprayed on the lightning rod, the conductive effect of the lightning rod will disappear. If such a problem is found during installation, you must inform The installer should completely scrape the plastic powder from the top of the lightning rod at least 20 cm from top to bottom, and then use the lightning rod to fix the top wire at the junction of the lightning rod and the rain cap to push out the plastic powder of the lightning rod, so that it can conduct normally. .
When installing the lamp, if it is an LED lamp, then the driving power behind the lamp is divided into neutral, live, and ground. When wiring, the ground must be connected to the pre-arranged main cable. If the ground of the driving power is If the cable is not connected, it is likely to be burnt during a thunderstorm. Then there is the processing of the terminal. The serial wire joints must be tinned, then wrapped with insulating tape, and then covered with flame-retardant wax tubes. The purpose of this is to avoid excessive aging of the wiring under high temperature and rain exposure. , Causing a short circuit.
Lamps, especially high-pressure sodium lamps, must pay special attention when installing. The fixing nut connecting the lifting beam must be tightened with a wrench. It is often seen that the lamp head of the high pole lamp on the square or roadside is drooping down, that is, it is not fixed properly. Caused by screws. In severe cases, it will cause personal injury if it falls.
High pole lights are generally composed of two or three sections of steel pipes. Pay special attention to the installation. When every two sections are inserted into each other, the insertion depth shall not be less than 60 cm. If the insertion is not in place, there is no need to worry about it. Falling down on its own, but it will affect the overall verticality of the high-pole lamp, and it will shake left and right. If it is plugged into place, there will be no problems.
The top part of the top section of the high pole lamp, that is, the position of the fixing hook, is connected by three M14 or M16 screws. When installing, it should be noted that these three screws must be stainless steel screws. Ignore this problem and use ordinary iron galvanized screws. After a long time, the iron screws will become severely rusted, making it difficult to decouple or unable to decouple. After the lamp has a problem, the lamp panel cannot be raised and lowered normally.
