Description

Technical Field

[0001] The invention belongs to the technical field of box culvert production systems, and in particular relates to an automated double-line prefabricated box culvert production system and a production method thereof. Background Art

[0002] At present, the production of integral prefabricated box culverts for shield tunnels in China mainly adopts the fixed pedestal method, which is a relatively traditional production method. The main processes still rely on traditional manual construction, and maintenance is also carried out by covering with tarpaulin and passing steam. The transportation flow between each process is mostly carried out manually, and the continuity and automation degree between each process are low.

[0003] Patent document CN116001078A discloses an automated double-line prefabricated box culvert production system and a production method thereof, comprising: S1. Automatically demoulding the mold at the demoulding station of the casting production line to obtain a finished integral prefabricated box culvert and an integral prefabricated box culvert mold respectively; S2. The integral prefabricated box culvert mold enters the casting production line and, driven by a hydraulic jacking system, flows from the right end to the left end of the casting production line and is supported by rollers; S3. Under the control of a control system, the integral prefabricated box culvert mold performs related processes at the corresponding station on the casting production line using corresponding supporting equipment. Industry; S4. When the integral prefabricated box culvert mold flows to the left end of the pouring production line, the sub-trolley runs to the bottom of the left end of the pouring production line, lifts up the integral prefabricated box culvert mold, and moves it to the left entrance of the steam curing line. The sub-trolley separates from the mother trolley and enters the steam curing line. The integral prefabricated box culvert mold is transported to the corresponding position in the independent steam curing kiln through the mold running track; S5. After the curing operation is completed, the sub-trolley moves the cured integral prefabricated box culvert mold from the corresponding position in the independent steam curing kiln to the right end of the pouring production line; S6. Repeat steps S1 to S5 to enter the next production curing operation. This method has a high degree of automation, and the automated production system and production method with independent curing conditions improve the mechanization and technological level of prefabricated box culvert production, reduce labor input, improve labor productivity, and stabilize and improve product quality to a certain extent. However, there are also obvious problems. For example, demoulding, mold cleaning and spraying, steel cage mold insertion, mold closing, pouring and vibrating, static stop station and finishing are all located on one side of the pouring production line, and rely on hydraulic cylinders, thrusters and rollers to move on the pouring production line. Multiple small-scale starts and stops are required, which requires high system control accuracy. The inertia during movement and stopping has a certain impact on the quality of the finished product of the integral prefabricated box culvert. Moreover, the required thread is relatively long, and can only operate on a single line, and dual-line synchronization is not possible, so the improvement in production efficiency is limited.
