Adjustable lamp bracket, easy to adjust the illumination angle. 1.3.2 Pole top with a travel limit switches, positioning hook and a guide means is provided with a corresponding retention hooks on the lamp panel frame positioning axis. Winch motor pull frame rose frame rose when positioning hook position, the frame moving upper limit pressure limit switch, the motor power and brake, lamp panel frame is linked to the three-dimensional positioning. 1.3.3 Pole top with a semi-circular rain cover, lamp panel is designed to be lowered to the ground 1.5 meters for repair, maintenance and convenient lighting safe operation. 1.4: Lifting the guide and the brake mechanism 1.4.1 The system consists of three groups of the pulley arm to 120 ° angle arrangement, fixed pole top fixed support bracket. Each set of pulley arm mounting lubricated sealed bearings, steel cable to prevent the stopper slide guide wheels. 1.4.2 hanging decoupling devices: Medallions raised hook system ensures a predetermined position in the cable hook traction and unloading means for generating a relative movement to reach the lock, detachable function. In normal use, the stainless steel wire rope in the unloading state, prolong the life of wire rope, ensure Medallions in windy conditions and other harsh stability and security. 1.5: 1.5.1 Lift systems lift system built-in drum winch, consists of motor, worm, reel and other parts. 1.5.2 worm drive mechanism with self-locking performance Medallions can stop at any position. Set over torque protection with automatic operation function. 1.5.3 deceleration mechanism flexible, lightweight self-locking. Optional gear ratio is reasonable, Medallions electric lift running speed is not more than 3.5 m / min. 1.5.4 lift system with electric control function, movements smooth, safe and reliable electric lift with a double anti-hoisting limit function, to ensure safety. Lifting mechanism by the motor, belts, turbo reducer, gear, wire rope Volume tube, stainless steel wire rope, pulley, automatic hang decoupling device and limit switches and other components. Stainless steel wire rope design safety factor greater than 8. Transmission poles in the lower part of the installation, easy operation, easy maintenance. 1.5.5 All fittings are made of stainless steel, and with anti-corrosion measures, all fasteners are taking against rotation. 1.6: electrical control systems 1.6.1 Distribution way: dual-circuit, three-phase four-wire, balanced power supply. 1.6.2 Control: electrical control and protection devices are fixed at the bottom of the poles of the control box, equipped with lighting and elevator control system control, can achieve full load lighting and part of the lighting, with light control and automatic control computer time to meet the different needs of users. 1.6.3 Cable selection of high-strength cables. The wires in the pole no joints, and leave some margin, the main cable nominal cross section in addition to meeting the requirements in line with the carrying capacity, but also to meet the mechanical tensile strength requirements. Connected to the power supply of copper wire, with a cross-section according to the number of lamps to determine the carrying capacity, each lamp connected to a copper wire having a cross section of 2.5mm2. 1.6.4 The control box has lighting control and Medallions lift control, lift control buttons Medallions leads from the control box from the pole operating radius greater than five meters, to ensure adequate safety distance. 1.7: 1.7.1 Pole top pole lightning protection and grounding means is provided with metal lightning rods, poles and electrical equipment have a good grounding protection. 1.7.2 The overall anti 32.6 m / s wind speed, intensity 7 earthquake. 1.8 pole embedded parts and basic reference 25 m pole lamp pole lamp base foundation drawings. 1.8: Pole after pole whole life by hot-dip zinc passivated, the useful life of more than 20 years. 1.9 the rest of the high pole lighting steel used, purchased parts and collaborative pieces, are in line with the relevant standards. Second, the electrical performance: 2.1 rated voltage: 380V / 220V50Hz 2.2 noise: <50DB (from front lamps, rear, left, right, 1 meter) 2.3 Wet Insulation resistance: measuring wet insulation resistance of not less than with 500V shake table 2MΩ. 2.4 wet dielectric strength: can withstand AC 50Hz, 2000V (rms) test voltage for 1min no breakdown or flashover. 2.5 Electric Shock Protection Class: Class Ⅰ Third, quality pole structure 3.1 pole structure assembly satisfies the following requirements: 3.2 pole body height tolerance ± 200mm; 3.3 Pole-sectional size to allow deviation ± 5mm; 3.4 light pole installation the rod axis vertical deviation of less than 3 ‰; 3.5 vertical pole shaft height deviation of less than 5 ‰; 3.6 at the maximum wind load strength to meet the conditions of displacement (around the value) of the shaft at the top of the shaft height of not more than 5 ‰ . Fourth, maintenance and repair: 4.1 lamps light year warranty, seven-year lamp warranty. Free replacement parts and provide service during artificial. Medallions fall to 4.2 after opening lower bearing repair, first remove the oil overhaul, there is nothing to check the wire rope wear and so on, the rope loose connections. 4.3 worm reducer cover, check the gear teeth for wear, worm or without axial movement. 4.4 gear, coupling section, for wear and so on. 4.5 the fastening screws loose. 4.6 Lubricants (fat) is dirty and should be replaced. Worm cabinets should ensure there is enough oil, non-oil or oil-less work. 4.7 Maintenance carried out every six months to check the main, identify problems promptly resolved, badly worn or damaged parts should be replaced.
