Embodiment 3

[0030] Embodiment 3, a hoisting method of the large-slope segment crane as described in Embodiment 2, the steps are as follows:

[0031] S1: The walking frame body 1 drives the entire segment crane to move to the top of the segment quick release device.

[0032]S2: The lifting cylinder 203 of the inclination adjustment mechanism 2 and the rotating cylinder 205 cooperate to adjust the height and angle of the vacuum suction cup 3 through the telescopic arm 202 and the swing plate 204, so that the vacuum suction cup 3 is in a state parallel to the segment 5, which can be inclined It can also be in an inclined state, which is convenient for fast grabbing of segments.

[0033] S3: The vacuum suction cup 3 is adjusted to an appropriate angle, gradually moves to the segment, and absorbs and grasps the segment on the segment quick release device.

[0034] S4: Then the oscillating oil cylinder 102 of the anti-falling mechanism 10 drives the closed-loop bracket 103 to swing, so that th...

Embodiment 5

[0040] Embodiment 5, a hoisting method of the large-slope segment crane as described in Embodiment 4, the steps are as follows:

[0041] S1: The walking frame body 1 drives the entire segment crane to move above the segment quick-release device; the longitudinal driving mechanism drives the trolley frame to fine-tune left and right on the walking 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 parallel to the segment, that is, the vacuum suction cup 3 and the segment are in a horizontal state, which is convenient for quickly grabbing the segment.

[0043] S3: The vacuum suction cup 3 is adjusted to an appropriate angle, gradually moves to the segment, and absorbs and grasps the segment on the segment quick release device.

[0044] S4: Then the swing cylinder 102 of th...

Abstract

The invention discloses a duct piece crane and a hoisting method. The problem that in the prior art, a duct piece crane cannot adapt to large-gradient shield construction is solved. The large-gradient pipe piece crane comprises a walking frame body, an inclination angle adjusting mechanism is arranged on the walking frame body, a vacuum suction cup is arranged on the lower portion of the inclination angle adjusting mechanism, and an anti-falling mechanism used for bearing pipe pieces is arranged on the vacuum suction cup. In the large-gradient state, the pipe piece in the horizontal state can be smoothly hoisted, the pipe piece can be smoothly placed on the pipe piece conveying device in the slope state, and the pipe piece hoisting efficiency and the construction safety coefficient in large-gradient construction are improved.

Description

technical field [0001] The invention relates to the technical field of segment hoisting in tunnels, in particular to a large-slope segment hoist and a hoisting method. Background technique [0002] During tunnel construction, when there are many large slopes with different values ​​in the tunnel excavation section, the conventional large-diameter segment cranes responsible for lifting segments cannot meet the normal construction needs and restrict construction efficiency. The conventional large-diameter shield segment crane moves back and forth along the crane beams arranged on both sides of the trailer, and vacuum suction cups are used to grab and transport the segments. This segment crane can only be adapted to the construction needs of small slopes. When there are many different large slopes (≥10°), the conventional segment crane will be tilted due to the overall tilt of the trailer, and the lifting clearance of the crane will be greatly reduced, and there is a risk that ...
