Background technique

As we all know, large storage tanks, especially large storage tanks in the petroleum industry, need to carry out daily maintenance operations such as overhaul, anti-corrosion, and heat preservation on the vertical wall of the storage tank and the accessory equipment installed on the vertical wall after long-term use. However, the height of the storage tank is usually Therefore, how to realize the high-altitude maintenance of storage tanks in a safe, effective and resource-saving manner has become an important issue; the existing storage tank maintenance work platforms usually include scaffolding work platforms and high-rise hanging baskets There are two ways of working platform; among them, the scaffolding working platform has the problems of high construction cost, long construction time, difficulty in material transportation and thus affecting the overall construction period. Taking a storage tank of 100,000 cubic meters as an example, the amount of materials used It is close to 100 tons, and there are many people involved in the operation, so there are high safety hazards in the process of building and dismantling; the high-rise basket-type work platform, the motor is usually set on the wind-resistant ring of the storage tank, and is suspended below by wire rope There are hanging baskets. Although this type of work platform requires less materials, it needs power support during the operation. If the storage tank is in working condition and there is a medium stored inside, it is difficult to use. Even if the storage tank is in an idle state, especially during the construction process During electric welding operations, convection between the arc current and the steel wire rope is likely to occur, and then the steel wire rope will be burned, which poses a greater safety hazard.
