Description

Technical Field

[0001] This utility model relates to the field of railway construction technology, specifically to a rapid segment turning device. Background Technology

[0002] In engineering, especially in tunnel construction, segment refers to precast concrete segments, which are factory-prefabricated reinforced concrete components. They are typically fan-shaped or arc-shaped. A segment is part of the entire tunnel lining and is a major component of the permanent tunnel lining. During or after the tunnel boring machine (TBM) excavates, a segment assembly machine assembles multiple segments into a complete segment ring under the protection of the shield tail. These segment rings are connected to form the tunnel's supporting structure and waterproof barrier.

[0003] For example, the announcement number CN211038679U is a subway segment self-turning device. The device includes a base, one end of the upper surface of the base is fixedly connected to one end of a telescopic rod, and the other end of the telescopic rod is fixedly connected to the bottom of a fixed groove. The subway segment is placed on the surface of the arc-shaped support plate, and the rotation of the threaded sleeve drives the threaded shaft to move up and down, so as to raise and lower the force plate, thereby achieving the effect of turning the subway segment on the surface of the arc-shaped support plate upright.

[0004] When the above-mentioned device is in use, the flipping structure is relatively simple, it cannot be adjusted according to the length of the tube segment, it cannot clamp and fix the tube segment, and it is not strong enough, so it is prone to breakage during flipping. Utility Model Content

The pipe segment is clamped and fixed using the cooperation of the movable and fixed clamps. Then, the motor drives the fixed clamp to flip, causing the flipping frame to flip to the other side, allowing the pipe segment to be quickly flipped. At the same time, an arc-shaped plate is installed, which is connected and fixed to the flipping frame. The axis of the arc-shaped plate is aligned with the axis of the flipping frame. When the flipping frame flips, the arc-shaped plate is driven to rotate synchronously, which can improve the stability of the flipping frame to a certain extent. With the cooperation of the arc-shaped plate, the flipping frame can be quickly flipped.

[0017] 2.
