High lamp mode of safe use

Light lifting system is through the motor, Electromagnetic brake type) Worm gear and worm reducer, safety coupling, main cable, vice wire rope, the rope, and components, such as driving lamp plate lifting pulley group. Worm gear and worm gear reducer of the self-locking capability is strong, compact transmission, the transmission ratio is large, in order to reduce the worm gear and worm gear ratio, reduce the rising torque, especially to increase a set of pulleys, lamp plate lifting speed is less than zero. 2 m/s. Lift high lamp main wire rope through the points are connected to the lamp panel vice wire rope rope device, can avoid because of main steel wire drawing and the formation of a pair of wire coil. Lord, vice wire rope type high strength and corrosion resistance was used for the 6 * 19 not rotating galvanized steel wire rope. Lifting pulley block is chosen by hot dip galvanized processing of A3 steel bracket, copper, stainless steel shaft pulley, ensure that under the condition of normal atmospheric rust not sensitive operation. All kinds of fasteners, washer, retainer ring, etc are also choose hot dip galvanized or stainless steel. Lamp plate is equipped with six set of guide pulley block and more than three sets of brake devices, in the lamp panel show 120 degrees in the process of lifting or lowering spread along the surface of the light pole guide wheel rolling, to ensure the lamp panel will not occur. Lamp panel guide wheel and outdoor light, touch the surface of the light pole assignments section surface choose rubber extrusion process. In order to ensure robust lamp plate to the limit position of active parking, lamp plate up and down movement limit switch function is strong, and is equipped with over travel protection. Light, lamp plate lifting is to rely on changes of motor rotation has completed. For security guard against theft, rectangular cavity is equipped with sealed door, sealing is equipped with a special door lock on the door.
