Hanging type movable working platform for storage tank maintenance

Abstract

The invention discloses an aerial maintenance working device, and particularly relates to a hanging type movable working platform for storage tank maintenance. The hanging type movable working platform for the storage tank maintenance can effectively save materials, and is short in building time, low in building cost, free of external power for supporting, and high in using safety. The hanging type movable working platform comprises a working hanging basket set, a first walking mechanism and a second walking mechanism, the first walking mechanism is arranged on the top of the working hanging basket set and relatively slides on a wind resistant ring of a storage tank through a pulley, the second walking mechanism is arranged on the side face of the working hanging basket set, the top end of the second walking mechanism abuts against and presses the outer wall of the storage tank through a pulley and relatively slides, the working hanging basket set comprises at least two working hanging baskets connected end to end, and a crawling ladder is arranged between the working hanging baskets.

Description

technical field [0001] The invention relates to the technical field of high-altitude maintenance operation devices, in particular to a special hanging movable operation platform for storage tank maintenance. Background technique [0002] 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 o...

[0002] 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 wire rope is likely to occur, and then the wire rope will be burnt, which poses a greater safety hazard
