Description

Technical Field

[0002] Reinforced concrete pipes are commonly used components in road or construction engineering technology, and are mainly used to transport fluids such as water, oil, and gas. At present, in order to facilitate the on-site installation of reinforced concrete pipes and improve installation efficiency, reinforced concrete pipes are mostly prefabricated and produced using prefabricated molds, and assembled on-site when used. During the on-site assembly process, in order to improve the sealing of the joints of reinforced concrete pipes, an annular sealing groove is provided at the socket of the reinforced concrete pipe for placing a sealing ring. Therefore, the prefabricated mold needs to first form the position of the sealing groove in the casting cavity during processing, so as to process a reinforced concrete pipe with a sealing groove formed at the socket.

A molding cavity is formed between the inner mold and the outer mold. At least two movable socket templates are arranged on the top end surface of the outer mold. The at least two movable socket templates are opposite to each other end to end and are arranged around the molding cavity. A telescopic power device is arranged on the outer end surface of the movable socket template. At least two movable socket templates are telescopically moved toward the molding cavity by the telescopic power device to form a socket on the outer end surface of the cement component in the molding cavity.

[0004] With regard to the above-mentioned related technologies, the inventors believe that in the processing of reinforced concrete pipes, each movable socket template of the forming device needs to be telescopically moved toward the forming cavity by a separate telescopic power device, that is, a telescopic power device needs to be provided on each movable socket template, which not only increases the production cost, but also makes the overall structure more complicated and inconvenient to assemble and disassemble.
