[0002] The long-line prefabricated component production line is composed of a long-line mold platform, a maintenance system and various special equipment. The long-line mold platform is composed of multiple single mold platforms (such as 4 meters × 9 meters) connected end to end and spliced ​​together. Various special equipment completes the cleaning, oil spraying, component molding, covering with insulation film and other tasks on the long-line mold platform, and the maintenance system is responsible for temperature and humidity control of the components for maintenance.

[0003] At present, the pipelines of the maintenance system of the long-line prefabricated component production line are unreasonable and there are many problems. For example, the entire long-line mold can only be heated and maintained at the same time, and a single mold cannot be maintained separately, resulting in a waste of resources, uneven heating and cooling of the mold due to poor pipeline circulation, and inconvenient maintenance. Summary of the invention

[0004] In view of the shortcomings and defects in the prior art, the purpose of the present invention is to provide a long-line platform prefabricated component production line maintenance system which has a reasonable structure, is simple and easy to control, and is convenient to maintain.

[0005] In order to solve the above technical problems, the present invention adopts the following technical solutions: a long-line prefabricated component production line maintenance system, characterized in that: it includes a single-mode platform and a steam source, an insulation layer is provided on the lower side of the single-mode platform, a maintenance pipeline is placed between the single-mode platform and the insulation layer, a temperature sensor is provided on the maintenance pipeline, one end of the steam inlet main pipe is connected to the steam source, and the other end is connected to the steam inlet and the steam dispersion pipe of the maintenance pipeline through an automatic on-off valve, the steam outlet of the maintenance pipeline is connected to the steam return main pipe through a check valve, a steam return buffer bag is provided at the end of the steam return main pipe, the steam return buffer bag is connected to the drainage tank through a steam trap and an automatic intermittent steam exhaust valve, the steam inlet main pipe is connected to the return water main pipe through a steam inlet drain valve at intervals, and the steam return main pipe is connected to the return water main pipe through a steam return drain valve at intervals.

[0006] As a further improvement of the present invention, the single-mode platform is fixed on the ground foundation, and a plurality of single-mode platforms are connected end to end to form a long-line mode platform.

[0007] As a further improvement of the present invention, the curing pipeline heats the concrete components on the single mold platform.

[0008] As a further improvement of the present invention, the steam diffusion holes of the steam diffusion pipe diffuse steam to between the single-mode platform and the insulation layer, thereby increasing the maintenance humidity of the components.

[0009] As a further improvement of the present invention, the temperature sensor, the automatic on-off valve and the control system constitute a closed-loop control.

[0010] Compared with the prior art, the present invention has the following beneficial effects:

[0011] (1) This maintenance system can realize single-mode control and individual maintenance of long-line mold platforms, thus avoiding waste of resources;

[0012] (2) This system is equipped with a separate return water main. The condensed water from the steam inlet main and the steam return main flows into the return water main through the steam inlet steam trap and the steam return steam trap, ensuring that there is no condensed water in the steam inlet main and the steam return main to hinder the steam flow.

[0013] (3) The intermittent exhaust of the steam return buffer improves the steam circulation efficiency, and the large volume of the steam return buffer effectively avoids the pipeline pressure fluctuation caused by intermittent exhaust;

[0016] (6) The single-mode single-control method ensures the convenience of maintenance and can repair the faulty part, effectively avoiding the situation where the entire line will be shut down due to a single equipment failure. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0020] In order to make the technical solution and beneficial effects of the present invention more clearly understood, the present invention is further described in detail below in conjunction with specific embodiments.

[0021] Figure 1This is a structural schematic diagram of a maintenance system for a long-line prefabricated component production line of the present invention. A single-mode platform 1 is fixed on a ground foundation, and an insulation layer 15 is provided on the lower side of the single-mode platform 1. The maintenance pipeline 2 is placed between the single-mode platform 1 and the insulation layer 15. Multiple single-mode platforms 1 are connected end to end to form a long-line platform. The maintenance pipeline 2 provides heat for the single-mode platform 1. The lower right corner of the maintenance pipeline 2 is a steam inlet, and the lower left corner is a steam outlet. The steam source 3 provides high-temperature steam for the maintenance system. One end of the steam inlet main pipe 4 is connected to the steam source 3, and two branches are provided on the steam inlet main pipe 4 for each group of maintenance pipelines 2. One of the branches supplies high-temperature steam to the maintenance pipeline 2 through an automatic on-off valve 5 to heat the concrete components on the single-mode platform 1; the other branch is connected to the steam dispersion pipe 7 through the automatic on-off valve 5, and the steam is dispersed to the space between the single-mode platform 1 and the insulation layer 15 through the steam dispersion holes on the steam dispersion pipe 7 to increase the maintenance humidity of the components. The steam outlet of each maintenance pipeline 2 is connected to the steam return main pipe 8 through a check valve 6. The steam return main pipe 8 has a steam return buffer bag 11 at the end. The steam return buffer bag 11 has two outlet branches, one outlet branch is directly discharged to the drainage pool 14 through a steam trap 9; the other outlet branch is directly discharged to the drainage pool 14 through an automatic intermittent steam exhaust valve 12. The steam inlet main pipe 4 is connected to the water return main pipe 10 through a steam inlet steam trap 16 at intervals for drainage of the steam inlet main pipe 4; the steam return main pipe 8 is connected to the water return main pipe 10 through a steam return steam trap 17 at intervals for drainage of the steam return main pipe 8.

[0022] The steam source 3 is turned on to provide the production line with high-temperature steam that meets the requirements. At this time, the steam inlet main pipe 4 is filled with high-temperature steam, and the condensed water generated in the steam inlet main pipe 4 flows into the return water main pipe 10 through the steam inlet drain valve 16, ensuring that there is no condensed water in the steam inlet main pipe to hinder the steam circulation.

[0023] When a component on a single mold platform 1 in the long-line mold platform needs to be cured and has been coated, the automatic on-off valve 5 of the steam inlet of the curing pipeline 2 on the lower side of the single mold platform 1 is opened, and high-temperature steam enters the curing pipeline 2 on the lower side of the single mold platform 1, and the component on the single mold platform 1 begins to heat up. According to the curing process requirements, the automatic on-off valve 5 connected to the steam dissipation pipe 7 corresponding to the single mold platform 1 is opened, and steam is dissipated to increase the curing humidity of the component.

[0024] After the steam in the maintenance pipeline 2 on the lower side of a single-mode platform 1 circulates, it enters the steam return main pipe 8 together with the condensed water through the connected check valve 6, and leads to the steam return buffer bag 11. The condensed water in the steam return main pipe 8 flows into the water return main pipe 10 through the steam return drain valve 17, ensuring that there is no condensed water in the steam return main pipe 8 to hinder the steam circulation. The check valve 6 effectively avoids the risk of the steam in the steam return main pipe 8 flowing back to the maintenance pipeline 2 when multiple mode platforms are maintained at the same time. The condensed water in the separate water return main pipe 10, the steam inlet main pipe 4 and the steam return main pipe 8 flows into the water return main pipe 10 through the steam inlet drain valve 16 and the steam return drain valve 17, ensuring that there is no condensed water in the steam inlet main pipe 4 and the steam return main pipe 8 to hinder the steam circulation.

[0025] One branch of the steam return buffer package 11 discharges the condensed water that has not been discharged in time from the steam return main pipeline 8 into the drainage pool 14 through the steam trap 9; according to the maintenance process setting, the other branch of the steam return buffer package 11 performs intermittent steam discharge at the set time through the automatic intermittent steam discharge valve 12 to improve the circulation efficiency of steam. The intermittent steam discharge of the steam return buffer package 11 improves the circulation efficiency of steam, and the large volume of the steam return buffer package 11 effectively avoids the pipeline pressure fluctuation caused by intermittent steam discharge.

[0026] After the temperature rises to the set upper limit temperature, the temperature sensor 13 transmits a signal to the control system, and the automatic on-off valve 5 is closed; after the automatic on-off valve 5 is closed, the component cools down to the set lower limit temperature, and the temperature sensor 13 transmits a signal to the control system, the automatic on-off valve 5 is opened, and the component is heated; this action is repeated until the entire maintenance process is completed.

[0027] The temperature sensor 13 and the automatic on-off valve 5 in the maintenance pipeline 2 of the maintenance system form a closed-loop control, which can accurately control the maintenance of the components. It can realize single control of the single mold station 1 of the long-line mold station and realize separate maintenance, thus avoiding waste of resources. The single control of the single mold station 1 ensures the convenience of maintenance, and can realize repair at the place where the fault occurs, effectively avoiding the situation where the entire line is shut down due to a single equipment failure.
