Description

Technical Field

[0001] The utility model relates to the technical field of shield segment production, in particular to a surface finishing and polishing device for shield segment production. Background Art

[0002] The shield segment is one of the main components used to construct tunnel pipes during the construction of the shield machine. The shield segment consists of two parts: the ring segment and the tail segment. It is made of high-strength anti-seepage concrete cast in a sealed mold and has the function of resisting special loads such as soil pressure and groundwater pressure.

[0003] When finishing the shield segment, the scraper can be manually lifted horizontally so that the scraper is close to the top surface of the mold. Through manual operation, the scraper is pushed to scrape across the top side of the mold to achieve finishing and smoothing of the shield segment. The operation of finishing and smoothing the shield segment can be completed only by the scraper. It is easy to use and simple to operate.

[0004] However, the current finishing and smoothing method has high labor intensity for workers during the processing, and two people are required to lift the scraper and keep the scraper in a horizontal state. As the processing time increases, the workers' delivery efficiency will also decrease. Therefore, a finishing and smoothing device for shield segment production is proposed. Utility Model Content

[0011] 1. The utility model adopts a structural design of a finishing and smoothing device for producing shield segments. By setting a finishing mechanism, a support frame is set on the production line of the shield segment. When the mold on the production line moves to the bottom side of the support frame, a V-shaped scraper or a circular scraper contacts the top side surface of the mold. At this time, the mold continues to move, thereby prompting the scraper to push the mounting seat up through the rotating table, thereby driving the lifting table to slide upward on the inner side of the support frame, compressing the first spring mounted on the slide rod, thereby pressing the scraper tightly against the mold surface through its elastic force, thereby performing a finishing and smoothing process on the shield segment.
