Electric adjustable type lifting streetlamp

Abstract

The invention discloses an electric adjustable type lifting streetlamp which comprises a hollow lamp post, a lamp arm arranged on the top of the hollow lamp post and a lamp head arranged on the end part of the lamp arm; a base box is fixedly arranged on the bottom of the hollow lamp post; a motor is fixedly arranged inside the base box; the motor is in transmission connection to a reduction mechanism through a motor shaft; a winding drum is arranged on the rotary shaft of the reduction mechanism; a slide block is arranged inside the hollow lamp post in a matched manner; the slide block is fixedly connected to the lamp arm through a slide slot in the side of the hollow lamp post; a slide wheel is arranged above the inner part of the hollow lamp post; the slide wheel is fixedly arranged on a slide wheel supporting base; a steel wire rope is wound on the winding drum; and the steel wire rope is fixedly connected to the slide block through the slide wheel. The electric adjustable type lifting streetlamp has the beneficial effects that: multiple limiting mechanism are adopted, and are used to realize lifting and self-locking safety by utilizing self-locking functions of worms and gears, limiting functions of ratchets and pawls, a regulating function of a limiting regulator and the like, so that maintenance safety can be guaranteed.

Description

technical field [0001] The invention relates to the technical field of road lighting public equipment, in particular to an electric adjustable lifting street lamp. Background technique [0002] At present, most of the street lamps on the market are fixed structures. When the lamps fail, workers need to use certain equipment to carry out maintenance work at high altitude, or the entire street lamp needs to be disassembled for maintenance. Maintenance is difficult. [0003] In response to these problems, many designers have designed a variety of unique lifting street lights. China Invention Application No. CN201510606018.0 discloses a lifting street lamp, including a lamp post, a mounting frame, a clamping device and a lamp head. The fixed pulley at the top of the pole lifts (or lowers) the street lamp, and the pawl in the clamping device clamps the slider in the light pole and stops at the desired position. Although this method solves the problem of lifting, it is time-con...

AI Technical Summary

Problems solved by technology

Although this method solves the problem of lifting, it is time-consuming and laborious. Once the pawl fails, there is no second layer of protection, which may easily cause accidents. The lifting speed can only be adjusted manually, and the lamp arm cannot be adjusted to adapt to the working environment.

Chinese Utility Model Application No. CN201120464855.1 discloses a liftable street lamp, which includes a pulley, a guide cable, a rotating shaft, a fixed rod, a lock ring sleeve, and a lock box. (or loosen) the guide wire, lift (or lower) the street lamp through the pulley on the top of the light pole, and use the lock ring to clamp the rotating shaft. This method also solves the lifting problem. The lock box is used to protect the important mechanism, but it is time-consuming and laborious. The design is rough, once the lock ring fails, it will easily cause accidents, the lifting speed can only be controlled manually, and the lamp arm cannot be adjusted to adapt to the environment

Chinese Utility Model Application No. CN201020680218.3 discloses a lifting street lamp, which consists of a lamp post, a lamp arm, and a lamp head. The top pulley raises (or lowers) the street lamp to the desired height, and binds the lower end of the rope to the lamp post. This method solves the lifting problem and has a simple structure, but it is more time-consuming and laborious than the above two methods, and the street lamp has Greater safety hazard, also unable to adjust the lamp arm to adapt to the working environment

Chinese Utility Model Application No. CN200920087543.6 discloses a lifting street lamp, which includes a threaded lamp pole, lamp cap, lamp pole base, lamp cap pole, lamp cap, lifting screw, a pair of bevel gears, etc. Turn the bevel gear to make the lifting screw rotate clockwise (or counterclockwise), and the threaded light pole rises (or descends) along the lifting stud. This method solves the problem of lifting. The lifting is stable, the structure is simple, and it can stop at the place stably. Need location, but time-consuming and labor-intensive, slow lifting speed
