Description

Technical Field

[0001] The invention relates to a shield machine segment posture adjustment device, belonging to the technical field of shield machines. Background Art

[0002] The shield machine is a special engineering machinery for tunnel excavation. During the construction of the shield machine, the cutter head located at the front of the shield machine excavates the tunnel body, and the segment assembly machine located in the tail shield assembles the segments to support the excavated tunnel in time. During the segment assembly operation, the segment assembly machine needs to grab the segment first, and then align the bolt holes of the grabbed segment with the bolt holes of the assembled segment. The assembly workers then use the segment bolts to connect the two segments. Therefore, the designed segment assembly machine needs to have 6 degrees of freedom to realize the three large-scale actions of axial movement of the segment tunnel, circumferential rotation of the tunnel, and lifting of the segment. At the same time, it must be able to control the segment to achieve three small-scale actions of left and right tilt, front and back pitch, and left and right rotation. Controlling the rapid adjustment of the posture of the segment is of great significance to improving the quality and efficiency of the segment assembly operation. The existing segment assembly system designs the rolling frame in the form of a telescopic inner cylinder and a telescopic outer cylinder to achieve the requirement of left and right tilting when fine-tuning the segment posture. This structural form is heavy and greatly reduces the vacuum chamber space of the vacuum system. Sometimes the vacuum chamber space needs to be designed inside the rotating frame, which reduces the safety of the vacuum system. Summary of the invention

[0003] The technical problem to be solved by the present invention is to provide a novel segment posture adjustment device in view of the defects in the prior art.

[0004] In order to solve this technical problem, the present invention provides a shield machine segment posture adjustment device, including a yoke, a fine-tuning device and a vacuum suction cup, a connecting shaft, a joint bearing, a connecting device, a No. 1 fine-tuning oil cylinder, a No. 2 fine-tuning oil cylinder, a No. 3 fine-tuning oil cylinder and a No. 4 fine-tuning oil cylinder.

[0005] The yoke includes a yoke left arm, a yoke right arm, a joint bearing sleeve, an upper connecting seat and a front connecting seat. The above components are formed into a closed box-shaped structure through sealing welding; the yoke provides support for the vacuum suction cup, and the internal closed space provides a vacuum cavity for the vacuum system. The vacuum suction cup is used to grab the pipe segment.

[0006] The fine-tuning device includes a connecting plate and a rib plate, the upper end of which is connected to the cylinder rod of the segment assembly machine's lifting cylinder through a pin shaft, and the lower end is connected to the yoke through a pin shaft; the fine-tuning device provides an articulation for the rotation of the yoke and the vacuum suction cup. When the left and right lifting cylinders of the segment assembly machine do not extend or retract synchronously, the segment can be tilted left and right. At this time, the fine-tuning device rotates under the action of force, providing adjustment for the change of the yoke's posture.

[0007] The vacuum suction cup comprises a gripping plate and a sealing strip.

[0008] The connecting shaft is a trapezoidal structure, with bolt connection holes processed at both ends.

[0009] The connecting device is formed by welding a second connecting plate and a third connecting plate.

[0010] Beneficial effects: The present invention controls the extension and contraction of the oil cylinder through the segment assembly remote control, which can quickly and accurately adjust the segment posture. The vacuum chamber is arranged inside the yoke, which is close to the vacuum suction cup, reducing the risk of vacuum system leakage. At the same time, the space is large enough to allow the vacuum suction cup to have a long pressure holding time when the power is off. The whole system has a simple structure and improves the efficiency of segment assembly. BRIEF DESCRIPTION OF THE DRAWINGS
