Description

Technical Field

[0001] The present application relates to the technical field of concrete pipe segments, and in particular to a concrete pipe segment hoisting and flipping device. Background Art

[0002] During the prefabrication production of precast concrete segments, the process from concrete pouring to shipment requires water curing of the segments, natural curing of the segments stacking, and other processes. In the existing segment production process, in order to ensure the number of segments stacked, most segments are stacked longitudinally and stacked in 4 layers; however, the segments need to be shipped with the inner arc facing up to ensure safety during transportation. To this end, the segments need to be flipped from the stacking state to the transportation state with the inner arc facing up. Most of the existing processes use a rubber rod to lay on the ground after manually lifting the segments. After the segments are placed on the rubber rod, the segments are tilted by moving the gantry crane forward and backward, and then the segments are placed in a state with the inner arc facing up. This flipping process causes great damage to the gantry crane, and during the flipping process, the concrete surface is prone to collision and damage, which requires manual repair, which is time-consuming and labor-intensive.
