150 w street light

Outside of some high lamp can be lifting, a lot of people that can lift the street lights are very curious, today will tell you about how to do this can rise and fall of the street lamp lifting. In elevating street lamps at the bottom of the rectangle in the inner chamber, in addition to

some high lamp can be lifted to the outdoors. Many people on the elevator street lamp is very curious. Today, I will tell you how to lift the street lamps. Within the elevator street light at the bottom of the rectangular cavity, in addition to the electrical control system, also installed the motor hoist system. Electrical control system installed inside a light pole, can avoid the lifting action failed harsh outdoor environment. Electrical control system provides a variety of circuit overload protection device. Copper base is widely used in silver plated circuit in the system of electric conductor, to ensure good contact electrical connection. The rise and fall of street lamp system by motor, Electromagnetic brake) Worm gear reducer, safety coupling, the main wire rope, wire rope, rope, activity lifting pulley block etc driving lamp panel. Worm gear reducer self-locking ability strong, compact transmission, the transmission ratio. Rising in order to reduce the worm gear and worm gear ratio, reduce torque, special pulley increases a set of activities, make the light board vertical velocity is less than 0. 2m/s。 Main wire rope through the rope, and lamp kits vice wire connection, avoid light, due to the main rope tensile steel wire winding. Main wire rope with high strength and corrosion resistance of 6 * 19 non-rotating galvanized steel wire rope. Increases with A3 steel bracket, stainless steel shaft pulley block and after hot dip galvanized processing copper pulley, ensure without corrosion under normal atmospheric conditions and flexible operation. All kinds of fasteners, washer, thimble and other parts is made of hot dip galvanized or stainless steel parts. Lamp plate more than 6 guide pulley block and 3 group of braking device. Show 120 degrees in the process of lamp plate lifting, the distribution of the guide wheel rolling along the surface of the light pole, to ensure the lamp panel does not swing. Lamp plate guide wheel and working part of the light pole surface contact surface using rubber extrusion process. In order to fully ensure the lamp plate automatic stop when reach the limit position, lamp plate shall be provided with reliable lifting limit switch, and should provide distance protection. By changing the direction of rotation of the motor to realize the rise and fall of the lamp panel. In order to prevent theft, hollow rectangular cavity is equipped with a sealed door, the door is also equipped with a special door lock. As a result, the drop light, more practical on the function, and can adapt to all kinds of lighting environment ( 。 jschindo。 com)
