Description

Inverted arm balance type wind pocket lamp post

Technical Field

The utility model relates to a wind pocket lamp, in particular to an inverted arm balance wind pocket lamp post.

Background

At present, a helicopter deck and a large crane are arranged on a maritime work platform and a special operation ship. In order to ensure the safe lifting of the helicopter, the large-scale crane on the deck carries out safe hoisting operation, and the marine platform needs to monitor wind direction and wind force in real time during working, so that wind pocket lamps are required to be arranged to complete data monitoring. The wind pocket lamp is usually arranged at the highest point of the platform structure so as to avoid interference of peripheral sundries and influence on the accuracy of data. The wind bag lamp mainly comprises a top lamp (with a lamp protecting cover), a wind bag (with a built-in steel ring) and a stand column, and the whole weight is about 80Kg. The upright post is generally made of steel pipes with the outer diameter of 80mm and the height of about 3 meters. As shown in fig. 5, the base bolts at the bottom of the column body of the lamp post of the wind bag are fixed, when the maintenance and replacement of the lamp of the wind bag are carried out, the base bolts are required to be disassembled, the maintenance and replacement work can be completed after the whole lamp post is laid down, and after the corresponding work is completed, the base bolts are required to be tightly fastened after the whole lamp post is vertical. The working range of the hoisting equipment cannot be covered in the whole process, and only manual operation can be performed. Because the head of the wind bag lamp is heavy and the size is large, even 2-3 persons can hardly put down the wind bag lamp safely and stably, and the wind bag lamp is extremely easy to damage secondarily during the process of reloading. In a word, the prior art has the problems of high operation difficulty, unsafety, easy secondary damage and the like.
