Light construction technical requirements: ( 1) Lifting the top of the light should be equipped with lightning rods, cover, 60 degree distribution of pulley block and hook system of the distribution of 120 degrees. High lamp manufacturers introduce cover can prevent rain water from entering the internal light pole, and avoid the rain belt wheel unit,
high lamp' Light, generally refers to more than 15 meters steel conical light pole and high-power modular fixtures are composed of new type of lighting. 】 The construction technology requirements:
( 1) The top of the hoisting high lamp shall be provided with lightning rod [ Lightning, and lightning protection needle, is used to protect buildings, tall trees, etc to avoid lightning device. 】 , cover, 60 degree distribution of pulley block and hook system of the distribution of 120 degrees. High lamp manufacturers introduce cover can prevent rain water from entering the internal light pole, and avoid the rain belt wheel parts such as corrosion. The pulley block is used to avoid the wire rope and cable winding. Hook system plan is very reasonable. When put down the lamp panel, can lift system operation, make the hook automatically, to ensure the safety of lifting operation finished, reliably uninstall wire rope, and extend the service life of wire rope.
( 2) In ascension type high lamp at the bottom of the rectangle in the inner chamber, in addition to electrical limit system, also install the motor and other promotion system. Electrical limit system installed in the interior of the light pole, can be avoided due to the harsh outdoor environment lead to the failure of lifting movement. Electrical limit set up various circuit overload protection device in the system. Copper base silver plating is widely used as a conductor of circuit in the system, in order to effectively ensure good contact with electrical connection.
( 3) The rise and fall of elevating high lamp system through motor ( Electromagnetic brake type) Worm gear reducer [ Worm gear reducer according to Q/MD1 - 2000 technical quality standard design and manufacture. 】 The safe coupling, Safety coupling ( Also called a torque limiter, torque limiter, safety clutch) , is one of the connection machine actively and work pattern in parts, the main function of overload protection, torque limiter is when required due to mechanical failure or overload torque than the set value, it is in the form of sliding limit the transmission of torque by the transmission system, after the overload situation disappear on its own recovery. 】 , and the main wire rope, and auxiliary steel wire rope, rope and mobile device to drive the lamp plate lifting pulley block. Worm gear and worm reducer 【 Worm gear and worm reducer is a kind of dynamic convey institutions, using gear speed converter, motor ( The motor) Number of rotary rotary deceleration to want, and get a larger torque. 】 The self-locking capability is strong, compact mains street light transmission, large transmission ratio. In order to reduce the worm gear and worm' Worm and worm wheel mechanism is used to transfer between two alternating axis movement and power. 】 The torque ratio and reduce rise, specially added a set of mobile belt pulley, the lamp panel speed is less than 0. 2M/s。
( 4) Lifting mast lamps and lanterns has two lifting limit method, manual and electric, light board can be reduced to safely and reliably from the ground. 2. 5 m height, convenient and protection work. Manual for the remote control device for length of 10 m, the operator will lamp plate lifting control within 5 m, in order to ensure the personal safety of operators.
