[0002] At present, in many large and medium-sized cities, fast and convenient subway transportation has become an important part of daily transportation. Urban subway construction is in a stage of rapid development. As an important prefabricated component in subway tunnel construction, pipe segments need to be used in large quantities. The pipe segments are in the shape of arc tiles, with a general diameter of less than 7 meters and a height of less than 1.5 meters. Each piece weighs about 4 tons, and the volume and weight are quite considerable.

[0003] The existing subway segment production generally requires mold-assisted shaping. When pouring concrete, the pipe mouth needs to be manually inserted into the pouring port, and then the gate is opened for pouring. This method requires the operator to work at height, and the problem of dripping concrete is prone to occur during the replacement of the pouring mold. The existing automatic concrete pouring mechanism is operated by multiple power mechanisms, which is complicated to operate and has a high cost. To this end, we provide an automatic concrete pouring device for subway segment production to solve the above problems. Utility Model Content
