Description

Technical Field

[0001] The present invention relates to the technical field of shield construction, and in particular to a segment transportation device for shield construction in a narrow space. Background Art

[0002] Chaobai Street Station is an existing station. The minimum distance between the bottom plate frame column and the side wall of the left line is 4.65m, which does not meet the trolley lowering width. Therefore, the shield machine trolley was modified. The trolley width was reduced to 4.5m, and the clearance inside the trolley was only 1.4m. A battery car marshaling width of 1.2m was used, equipped with 4 soil buckets, 1 mortar car, and 2 segment cars. After the left line was excavated to 104m (i.e. 65 rings), the negative ring was removed, and the 1#-5# trolleys were hoisted out. After the ground was widened to the original width of 5.5m, the 1#-6# trolleys were hoisted down the well, and the battery car was used to push the tunnel and connect all of them with the shield machine, and normal excavation began. The width of the pipe segment is 1.6m, and it cannot be transported to the shield tail assembly area by an electric car in the conventional way in the modified trolley space. Therefore, a pipe segment flipping conveyor fixed on the electric car was spontaneously developed. The pipe segment is first placed vertically on the electric car through the developed equipment. After being transported to the shield tail, the pipe segment is flipped and flattened by the flipping machine, and then the shield machine pipe segment assembly operation is carried out normally.

[0022] The construction pipe segment is hoisted to the arc seat 9 and placed horizontally. The rotary drive mechanism 10 rotates forward and the connecting chain 11 is slowly released. Due to the asymmetrical arrangement of the rotating seat 20, the arc seat 9 close to the stand a5 is tilted downward under the action of gravity until the pipe segment is almost upright. The limit rod 12 limits the slippage of the pipe segment. The telescopic mechanism b15 controls the pipe seat b4 to retract and reduce the width of the device. At the same time, the telescopic mechanism c16 controls the pressure plate 18 to move forward and press on the pipe segment to limit the pipe segment and ensure its stability during movement. In addition, the telescopic mechanism a7 controls the pad 8 to support the arc seat 9 from the bottom to improve its safety. Since the width of the device is reduced, it can effectively pass through the narrow space of the shield and has good practicality.
