Light lifting and lowering structure for nuclear power stations

Abstract

The invention discloses a light lifting and lowering structure for nuclear power stations. The structure comprises a pushing rod component comprising an outer fixed tube, a middle movable tube, an inner movable tube, a first nut-screw pair, a second nut-screw pair and a worm-gear pair, a driving motor provided with a rotary motor shaft, an LED light placed below the inner movable tube, and a lightconnecting flange placed between the inner movable tube and the LED light and fixedly connected with the inner movable tube and the LED light, wherein the rotary motor shaft and a worm of the worm-gear pair have the same transverse axis, and the rotary motor shaft extends into the outer fixed tube and is fixedly connected with the worm of the worm-gear pair. The structure has the advantages thatstability of the LED light and the pushing rod component is improved in the installing and using processes, the anti-seismic capacity and the wind resistance capacity are high, and the structure meetsthe light requirements of the nuclear power stations.

Description

technical field [0001] The invention relates to nuclear power facilities, in particular to a lifting lamp structure for a nuclear power plant. Background technique [0002] Chinese invention patent application CN108105669A discloses "a high-power narrow-beam LED lamp for nuclear power plants" which has a long suspension rod, a U-shaped fork and an LED lamp. The disadvantages of the above structure are: 1. LED lamps do not have a lifting function, that is, once the installation height is determined, it is limited and cannot adapt to changing working conditions; 2. The long suspender is designed as a single pole, and its seismic and wind resistance Poor, high-risk workplaces such as nuclear power plants often require products with higher safety factors; 3. In narrow working conditions (such as nuclear power plant shafts), limited by the long length of the long boom, the installed During the process, care should be taken to avoid touching the surrounding facilities, and the in...
