Description

Technical Field

[0001] This utility model relates to the field of tunnel segment production technology, and in particular to a deburring and grinding equipment for large-diameter tunnel segment production. Background Technology

[0002] Tunnel segments are the most important structural components in shield tunnel construction, widely used in subway, highway, railway, water conservancy, and integrated utility tunnel projects. With the increasing diameter and mileage of tunnel projects, the demand for large-diameter (usually referring to an outer diameter greater than 6 meters) concrete tunnel segments, as their core components, is growing daily. Large-diameter tunnel segments are characterized by their large size, heavy weight, complex curvature, and high precision requirements. Their quality directly affects the integrity, waterproofing, and long-term safety of the tunnel structure. During the production process, concrete is poured into precision-machined steel molds, compacted by vibration, cured, and then demolded. After demolding, burrs and flash inevitably form on the joint surfaces (such as longitudinal and circumferential joints), around bolt holes, on the inner curved surfaces, and at the edges of the tunnel segments due to concrete bleeding, slight deformation of the mold, or gaps in the sealing strips. Therefore, we designed a burr-removing device for the production of large-diameter tunnel segments. Utility Model Content

[0010] Compared with related technologies, the deburring equipment for large-diameter pipe segment production provided by this utility model has the following advantages: 1. This utility model provides a deburring and grinding device for large-diameter pipe segments. A sliding drive motor located at the top of both sides of the grinding machine disc controls the rotation of a drive threaded rod within a moving limit groove, thereby moving a sliding adjustment disc to adjust the distance between the two connecting arms. A first fixed gripper provides support at the bottom of the pipe body; a vertical motor drives the lifting threaded rod to rotate, causing the lifting slider to slide inside the lifting platform, thus adjusting the height of the second fixed gripper. By adjusting the distance between the second and first fixed grippers, they are clamped and fixed to the pipe body surface. The adjustable distance between the two connecting arms allows for fixed connections at different positions, enhancing the load-bearing stability during pipe processing and ensuring the accuracy of subsequent deburring.

[0011] 2. This utility model provides a deburring and grinding device for large-diameter pipe segment production. A spacing adjustment motor controls the rotation of a spacing adjustment threaded rod, which in turn moves a spacing adjustment slider inside the processing machine, thereby adjusting the relative position between the grinding device and the pipe body. The grinding roller can extend into the pipe body and is driven by a grinding motor to rotate its shaft. The grinding contact balls on the grinding roller grind the burrs on the pipe body surface. The arrangement of multiple grinding rollers allows for simultaneous processing of different locations on the inner wall of the pipe, effectively improving grinding efficiency.
