DETAILED DESCRIPTION

[0017] Based on the embodiments of the present utility model, all other embodiments obtained by ordinary technicians in the field without making any creative work shall fall within the scope of protection of the present utility model.

[0018] Example: See Figure 1-2 The utility model provides a technical solution: a tube shell preparation mold for PCCP pipes. This solution takes into account that the traditional PCCP pipe shell spraying process cannot guarantee the surface uniformity and flatness, and is prone to breakage during subsequent laying and use. Based on the above content, this case sets the following technical means;

[0019] Specifically, the device at least includes an equipment base 1, a mold shell 2, a rotating seat 3, a pair of fixed brackets 4, a pair of first telescopic rods 5, a pair of stable brackets 6; a pair of spray racks 7, a plurality of spray heads 8, a slurry storage tank 9, a pair of mud pumps 10 and a pair of molding and leveling components;

[0020] The rotating seat 3 supports the lower end of the PCCP tube core, and then stably clamps the top of the tube core through the retractable and movable stable bracket 6 installed at the output end of the first telescopic rod 5. The rotating seat 3 drives the tube core to rotate, and the mud pump 10 draws out the mud in the slurry storage tank 9 and sprays it through the spray head 8 on the spray rack 7 to adhere to the outer wall of the tube core, thereby realizing the preparation and processing of the tube shell. While spraying, the surface is scraped and leveled by the forming and leveling component installed on the mold shell 2.

[0021] More specifically, the molding and leveling assembly includes: a pair of second telescopic rods 15, a pair of mounting blocks 16, a rotating molding roller 17 and a molding scraper 18;

[0022] When the rotating structure drives the tube core to rotate and cooperates with the spray head 8 to perform tube shell spraying processing, the output end of the second telescopic rod 15 embedded in the mold shell 2 extends to drive a pair of mounting blocks 16 to move inward, so that the rotary forming roller 17 fits the outer wall of the tube shell. At the same time, the forming scraper 18 and the rotary forming roller 17 are in the same roundness orientation. When the tube shell rotates, it is first scraped and leveled by the forming scraper 18 and then formed and extruded by the rotary forming roller 17 to ensure the uniformity and flatness of the tube shell.

[0023] In the specific implementation process, further, a pair of fixing brackets 4 are installed on the mold shell 2 through fixing bolts 11.

[0024] In the specific implementation process, further, a pair of stabilizing brackets 6 are provided with rotating rollers 12 .

[0025] In the specific implementation process, further, a pair of mud pumps 10 are connected to the slurry storage tank 9 and a pair of spray racks 7 through a slurry delivery pipe 13 .

[0026] In the specific implementation process, further, a support frame 14 is installed on the pair of first telescopic rods 5 .

[0027] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
