A shield segment clamping device

Abstract

The invention discloses a shield segment clamping device, which includes a moving system, a loosening system, a spraying system, a cleaning system, a suction system, a magnetic suction system, and a positioning system arranged along the moving system. The loosening system and the suction system peel off the veneer of the segment attached to the mold, and then in the subsequent magnetic suction system, the complete segment can be pulled out of the mold with high efficiency and high quality, and the magnetic suction system is divided into Multiple magnetic attraction points work independently, so that the device can flexibly handle segment products of various sizes, which is beneficial for manufacturers to expand and enrich production lines. The invention works sequentially through the magnetic suction system and the position adjustment system to stack and place the segments in a concave-convex manner. On the one hand, it reduces the risk of damage and rupture of the bottom segment due to excessive pressure, and reduces storage loss. On the other hand, it is convenient for the stacked segments to be transported by hanging.

Description

technical field [0001] The invention relates to the technical field of shield tunneling segment production and manufacturing, in particular to a shield tunneling segment clamping device. Background technique [0002] With the rapid development of the national economy, the country has continuously invested heavily in the field of infrastructure construction, and the supporting industrial production capacity related to people's livelihood, such as food, clothing, housing and transportation, has been greatly improved. In terms of transportation, whether it is high-speed rail traffic across provinces, motor vehicles or intercity trains used in inter-provincial traffic, light rail or subway used in cities, a large number of obstacles need to be used in tunnels. In the process of manufacturing tunnels, a large number of shield segments are needed, and their quality, manufacturing cost and efficiency have become an important link to measure the safety and cost performance of tunnel...

Problems solved by technology

[0003] At present, in the production process of shield tunneling segment, it is often difficult to guarantee the production efficiency and quality uniformity of the shield tunneling segment because of the slow operation or large damage of taking the segment out of the mold.

At present, most of the related devices and equipment have the following problems: (1) Most of the existing shield segment production systems only use integral magnetic suction to forcibly pull the segments out of the mold. During the manufacturing process, the segment will be highly compatible with the mold and because of the large surface friction coefficient, it will be difficult to remove or even cause the segment to be worn and broken. Secondly, because of the overall magnetic attachment method, the corresponding tube The size of the segment product is single, which is not conducive to the expansion of the production line; (2) the existing segment manufacturing device seldom cleans the segment surface. As a result, the magnetic attraction effect is poor. On the other hand, because the segments need to be stacked and stored, if there is a large amount of impurities and debris, it will cause slippage during the stacking process, and even the risk of dumping after a large amount of stacking; (3) the current related equipment Most of the clipped segments are directly placed in a concave and convex manner. Stacking in this way can easily lead to damage or even rupture of the bottom segment, which increases storage loss and requires additional labor and labor. Segment inversion operation
