[0002] Shield segments are the primary assembly components of shield construction and serve as the inner barrier of the tunnel, resisting soil pressure, groundwater pressure, and other special loads. Segment production is often completed on a production line with various production areas. Segment molds are loaded onto transport vehicles and transported to designated locations.

[0003] However, due to the heavy weight of the segment mold, the segment mold often moves due to inertia and cannot stop at the designated position, affecting the transportation of the segment mold and reducing the production efficiency of the entire production line.

[0004] Existing technology 202121886797.1 discloses a shield segment mold positioning device. Although it solves the above problems, it requires four hydraulic cylinders to complete, which greatly increases the cost. Utility Model Content

[0007] Preferably, the two groups of limit assemblies include grooves arranged on the base at the two guide rails and dividing the two guide rails into two sections, a lifting plate arranged in the groove, two limit slide grooves arranged on both sides of the inner wall of the groove, two extension plates correspondingly arranged on both sides of the lifting plate for sliding in the two limit slide grooves respectively, a docking plate arranged in the groove and one end hinged to the middle of the bottom surface of the lifting plate and the other end hinged to one end of the connecting rod assembly, and four limit plates with one end respectively located directly above the two grooves and the other ends respectively hinged to the four sections of guide rails on both sides of the two grooves; the four limit plates are consistent with the top size of the guide rails and are on the same horizontal line.

[0008] Preferably, the clamping assembly includes a driving hydraulic cylinder arranged in the middle of the top surface of the support frame and with an output section passing through the top surface of the support frame facing the base, a fixed plate arranged on the output section of the driving hydraulic cylinder, two clamping plates rotatably arranged on both sides of the support frame and with the clamping ends extending into the support frame, and two connecting plates with one end hinged to both sides of the fixed plate and the other end connected to the clamping ends of the two clamping plates.

[0009] Preferably, buffer pads are provided on the clamping ends of the two clamping plates.
