Example Embodiment
[0030] Embodiment 3, a kind of hoisting method of the large-slope segment hoist as described in Embodiment 2, the steps are as follows:
[0031] S1: The walking frame 1 drives the entire segment hoist to move to the top of the segment quick-release device.
[0032]S2: The lifting cylinder 203 of the inclination adjustment mechanism 2 cooperates with the rotating cylinder 205, and the height and angle of the vacuum suction cup 3 are adjusted through the telescopic arm 202 and the swing plate 204, so that the vacuum suction cup 3 is in a state parallel to the tube piece 5, which can be inclined It can also be in an inclined state, which is convenient for quick grabbing of the segment.
[0033] S3: The vacuum suction cup 3 is adjusted to an appropriate angle, gradually moves to the segment, and adsorbs and grasps the segment on the segment quick release device.
[0034] S4: Then the swinging oil cylinder 102 of the anti-dropping mechanism 10 drives the closed-loop bracket 103 to...
Example Embodiment
[0040] Embodiment 5, a hoisting method of the large-slope segment hoist as described in Embodiment 4, the steps are as follows:
[0041] S1: The traveling frame body 1 drives the entire segment hoist to move to the top of the segment quick-release device; the longitudinal drive mechanism drives the trolley to fine-tune left and right on the traveling frame body, so that the vacuum suction cup can be accurately located at the lifting point.
[0042] S2: The inclination adjustment mechanism 2 adjusts the height and angle of the vacuum suction cup 3 through the chain hoist, so that the vacuum suction cup 3 is in a parallel state with the tube piece, that is, the vacuum suction cup 3 and the tube piece are in a horizontal state, which is convenient for quickly grabbing the tube piece.
[0043] S3: The vacuum suction cup 3 is adjusted to an appropriate angle, gradually moves to the segment, and adsorbs and grasps the segment on the segment quick release device.
[0044] S4: Then th...
