Abstract

The invention provides an antenna housing top sling device and a manufacturing and mounting method thereof and aims to solve the problems that the space in the antenna housing is limited, the liftingequipment is difficultly erected, the machining difficulty is high, the cost is high, the structure strength of the antenna housing top plate is not enough for additionally mounting the lifting equipment, the antenna housing has no corrosion resistance, the length of the steel wire rope cannot be changed, the universality of the steel wire rope is poor, and the connection part between the steel wire rope and the antenna housing is easily damaged, is difficultly repaired and is high in repairing cost. The antenna housing top sling device comprises a main lifting point assembly, N secondary lifting point assemblies, N fixed pulley components, N movable pulley components and a steel wire rope, wherein the N secondary lifting point assemblies are mounted on the top of an antenna housing; the centers of the N secondary lifting point assemblies are located on the same horizontal plane and are arranged on the same circumference; the N fixed pulley components are mounted on the N secondary lifting point assemblies through a one-to-one correspondence manner; the N fixed pulley components are located above the N movable pulley components; the N movable pulley components are uniformly distributed at the periphery of one main lifting point assembly. The antenna housing top sling device is used for lifting the equipment in the antenna housing.

Description

technical field [0001] The invention relates to a sling device at the top of a radome and a manufacturing and installing method thereof. Background technique [0002] The sling device on the top of the radome is a device designed to realize the hoisting function inside the radome. The device is generally installed on the top of the radome. It is required that the device has the ability to bear the design weight and has corrosion resistance. [0003] The main reason for the invention of the sling is that in the later stage of the radar and radome installation, when the radar or radome needs to be hoisted for maintenance and repair, due to the limited space in the hood, it is difficult to erect the hoisting equipment, and it is easy to cause damage to the radar due to collision. Adding hoisting equipment directly on the top of the radome is easy to cause damage to the radome, and there is a certain risk. Moreover, the cost of the sling device is high, and the maintenance cost ...
