[0032] The working process of the cast pipe cement lining arrangement system provided by the utility model is as follows:
[0033] When the cast pipes enter the corresponding positions of the spigot plug installation station 1 and the bell mouth plug installation station 15 on the distribution step beam 2, the operators install the bell mouth plugs and the spigot plugs at the two ends of the cast pipes respectively. Then the distribution step beam 2 transports the two cast pipes to the working position of the main double-station distribution device 3 for distribution. During the distribution process, the longitudinal transport vehicle 4 enters the main line area. After the distribution is completed, the distribution step beam 2 transports the two cast pipes to the longitudinal transport vehicle 4, and the longitudinal transport vehicle 4 transports the two cast pipes to the front end of the branch line lining step beam 8. The branch line lining step beam 8 takes the two cast pipes from the longitudinal transport vehicle 4 and transports them to the branch line double-station cement lining machine 9 for centrifugation. After the centrifugation is completed, the branch line lining step beam 8 transports the cast pipes to the corresponding positions of the branch line spigot plug dismounting station 10 and the branch line bell mouth plug dismounting station 17 on the branch line lining step beam 8. The operators dismount the bell mouth plugs and the spigot plugs at the two ends of the cast pipes, hang the spigot plugs on the spigot plug returning device 12, and hang the bell mouth plugs on the bell mouth plug returning device 11. The spigot plugs are returned to the corresponding area of the spigot plug installation station 1, and the operators take off the spigot plugs for standby. The bell mouth plugs are returned to the corresponding area of the bell mouth plug installation station 15, and the operators take off the bell mouth plugs for standby.
[0034] After the distribution step beam 2 transports the two cast pipes to the longitudinal transport vehicle 4 in the above working process, the double-station distribution device 3 distributes another two cast pipes which are about to enter the main line. After the distribution is completed, the distribution step beam 2 transports the two cast pipes to the front end of the main line lining step beam 5, and the main line lining step beam 5 takes the two cast pipes from the distribution step beam 2 and transports them to the working position of the main line double-station cement lining machine 6 for centrifugation. The cast pipes on the main line after the centrifugation are transported by the main line lining step beam 5 to the corresponding positions of the main line spigot plug dismounting station 7 and the main line bell mouth plug dismounting station 16 on the main line lining step beam 5. The operators dismount the bell mouth plugs and the spigot plugs at the two ends of the cast pipes on the main line, hang the spigot plugs on the spigot plug returning device 12, and return the spigot plugs to the corresponding area of the spigot plug installation station 1. The operators take off the spigot plugs for standby. The bell mouth plugs are hung on the bell mouth plug returning device 11, and the bell mouth plugs are returned to the corresponding area of the bell mouth plug installation station 15. The operators take off the bell mouth plugs for standby.
[0035] It should be noted that since the time required for centrifugation and centrifugation assistance of the cast pipes is much longer than the time required for distribution, which can be 2 times the distribution time, the distribution process of the main double-station distribution device 3 can be completed during the centrifugation of the main line double-station cement lining machine 6 and / or the centrifugation of the branch line double-station cement lining machine 9. The standby double-station distribution device 13 is an optional equipment for customers.

The main line and branch lines allow for separate cement lining operations, significantly improving production efficiency and reducing equipment investment costs compared to multi-station lining equipment with a linear layout. The parallel arrangement of the main and branch lines effectively reduces the length of the finishing line, thus minimizing the plant's footprint. More importantly, the separate arrangement of the main and branch lines effectively solves the equipment maintenance problem in the lining area, allowing for maintenance shutdowns without affecting the entire finishing line's production, reducing maintenance costs and increasing production efficiency. The process layout of this utility model has shown excellent application results.
[0037] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it; although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications to the technical solutions described in the foregoing embodiments, or equivalent substitutions for some or all of the technical features, do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
