Description

Technical Field

[0001] The present application relates to the technical field of hoisting and turning equipment, and in particular to a prefabricated part turning hoist and a method of using the same. Background Art

[0002] At present, most of the drainage ditches are prefabricated parts with concave troughs cast by concrete, which can replace traditional drainage ditches and can be prefabricated in advance at the prefabrication site and then transported to the construction site for splicing. The construction speed is fast and manpower and material resources are saved. Among them, the prefabricated parts adopt the horizontal bottom-mouth casting method during prefabrication construction. The center of gravity of the trough prefabricated parts is in the inner cavity of the trough body, and the top-mouth forward installation is adopted during the installation on the construction site. Therefore, the finished product needs to be turned 180 degrees and the prefabricated parts are installed with the notch facing upwards.

[0003] At present, when the trough body is flipped, a crane and a nylon soft sling are required. One end of the nylon soft sling is tied to any side wall of the trough body, and the other end is connected to the crane and slowly lifted. The trough body gradually leaves the ground and is flipped with the center of gravity shifted, so that the trough body slot faces both sides. Then the trough body is placed on the ground, and after adjusting the binding position of the nylon soft sling, the lifting is continued until the trough body slot faces upward, and then the trough body is hoisted and placed on the ground to complete the flipping of the trough body.

[0004] Regarding the above-mentioned related technologies, nylon soft slings are used to bind the trough body. During the flipping process, workers are required to manually adjust the position of the nylon soft slings. The inventor believes that the prefabricated parts fall to the ground many times, the operation process is fragmented, the flipping efficiency is low, and the safety is insufficient.
