Description

Technical Field

[0001] The present invention relates to the field of mechanical engineering, in particular to a novel large vertical water pump hoist. Background Art

[0002] When these pumps need to be installed, repaired, or replaced, lifting becomes an essential step. Traditional large vertical pump lifting equipment has exposed many drawbacks during actual operation.

[0003] Due to the sheer size and weight of large vertical water pumps, lifting requires the use of thicker wire ropes, along with auxiliary tools such as clasps and slings. However, this not only complicates the preparation for lifting, but also makes the actual tying process challenging, labor-intensive, and time-consuming. Attached components on the pump, such as flanges and connectors, are often arranged asymmetrically. This makes it extremely difficult for operators to determine the optimal tying position when tying the pump. Without a precise tying position, the pump's stability and balance cannot be guaranteed during the lifting process, significantly increasing the safety risks of the lifting operation. To level a large vertical water pump, it must be suspended and adjusted to a horizontal position. However, due to the sheer size and weight of large vertical water pumps, the wire rope can easily shift and become stuck during this adjustment process. If this occurs, the pump is likely to tilt or even jolt, posing a serious threat to the safety of on-site workers and surrounding equipment. Most traditional lifting equipment is difficult to maneuver. Since large vertical water pumps are often installed in specific locations, lifting operations may require relocation. Existing lifting equipment can be inflexible or difficult to accurately position during movement, resulting in low lifting efficiency. Furthermore, traditional lifting equipment has limited adaptability to varying working conditions and cannot effectively adjust to factors such as the specific installation environment of the pump and surrounding obstacles, significantly limiting its scope of application.
