Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of pipeline repair, and particularly relates to a UV-cured inner lining repair construction device and a process thereof. BACKGROUND

[0002] Many pipelines in cities in China are in poor condition due to long-term disrepair, and early pipelines in cities are mostly concrete pipelines, ceramic pipelines and culverts, which are more prone to damage, including deformation and collapse. In order to repair them, the state has proposed a development plan for the construction of urban pipeline networks in the "Twelfth Five-Year Plan", and has proposed to comprehensively update and transform backward pipelines with a service life of more than 50 years, such as gray cast iron pipelines and asbestos pipelines.

[0003] Currently, common update and transformation technologies include the insertion method, the folding lining method, the spraying repair method and the original taste fixation method. The UV-cured inner lining repair technology is one of in-situ curing methods, which cures the inner lining by irradiating it with ultraviolet light when it is attached to the inner wall of the pipeline, so as to achieve the purpose of repairing the pipeline. This technology has many advantages, including fast construction, no joints and smoothness of the repaired inner lining, close attachment between the inner lining and the pipeline, no need for grouting and small loss of flow area.

[0004] However, this technology has encountered some problems in the application of repairing pipelines in China: 1) the UV repair technology in China started late and lacks experience; 2) the UV-cured inner lining repair technology mainly relies on the shape of the original pipeline to repair the inner lining, and due to the complex internal conditions of the pipeline, there are many defects such as deformation, rupture and exploration structure. In view of the above defects, the pipeline damage needs to be pretreated before inner lining repair. The present application provides a pipeline inner wall pre-repair construction device and a UV-cured repair process, which pretreats the pipeline rupture and deformation before performing UV lining repair to avoid damage to the inner lining when pulling it.

[0022] The advantages of this invention compared to existing technologies are as follows:

[0023] 1) By pressing the support ring through the pressing mechanism, not only does the top plate in the pressing mechanism press against the damaged or deformed parts of the pipe inner wall to restore them initially, but the top plate can also push the support ring to continuously expand its inner diameter. Finally, with the continuous pressing of the hydraulic cylinder, the support ring is made to fit tightly against the inner wall of the pipe, supporting the inner wall of the deformed or damaged area of ​​the pipe. This not only achieves initial repair, but also avoids the situation of being scratched or damaged when pulling in the inner lining hose.

[0024] 2) The support ring is composed of a support plate assembly, a third support plate, and a tension spring. Under the continuous pushing action of the top plate in the pressing mechanism, the support ring allows relative sliding between the support plate assembly and the third support plate, thereby increasing the diameter of the support ring to accommodate pipes of different diameters for supporting and pre-repairing. Since the first set of teeth on the support plate assembly and the second set of teeth on the third support plate are set in opposite directions, the mutual meshing of the first and second sets of teeth restricts the reverse sliding of the support plate assembly under pressure, realizing the supporting effect on the pipe deformation repair area, preventing the repair area from deforming again, and ensuring that the liner can be smoothly inserted into the pipe without being damaged.

[0025] 3) Power is provided by a third motor, and the power is transmitted through the transmission gear to control the rotation of the first gear, the fixed shaft, and the fixed arm. This adjusts the top pressure mechanism to align with the pipe deformation area. At this time, the hydraulic cylinder top shaft in the top pressure mechanism is in the retracted state. Then, the locking mechanism locks the second gear through the insert block to prevent the fixed arm and the top pressure mechanism from rotating and changing position. When the top pressure is applied to repair the inner wall of the pipe, the top plate and the hydraulic cylinder can be aligned with the pipe deformation area, so as to maximize the top pressure repair effect.

[0059] When the pipeline is repaired by using the ultraviolet light curing lining, the pipeline needs to be dredged and drained first; meanwhile, some pipelines may have structural defects such as collapse, rupture, and deformation; the structural defects need to be preliminarily recovered to avoid the lining material being damaged and deformed by the damaged and deformed part when the sleeve is pulled, so that the lining material cannot be inflated to tightly fit the inner wall of the pipeline.

[0060] Pipeline preliminary pre-repair process: the oil station 24 supplies power to the hydraulic motor 38 and the oil cylinder 132, the hydraulic motor 38 drives the walking mechanism 3 to walk, and then drives the whole device to move; the second motor 34 drives the screw rod 31 to rotate, so that the first adjusting disc 35 moves along the third guide shaft 32, so that the first supporting arm 36 controls the second supporting arm 37 to open or retract to adapt to the walking repair of pipelines with different diameters.

[0061] When the damaged and deformed part needs to be repaired, first walk to the deformation area, and then retract the jacking shaft and the insert block 271 to unlock the second gear 262 and the rotating shaft 26 through the first electric push rod 273; then provide power through the third motor 51, control the first gear 121 and the fixed shaft 12 and the fixed arm 11 to rotate through the transmission gear 52, and then adjust the jacking mechanism 13 to align the pipeline deformation area, at this time the jacking shaft in the oil cylinder 132 of the jacking mechanism 13 is in the retracted state, then the locking mechanism 27 locks the second gear 262 through the insert block 271, to prevent the fixed arm 11 and the jacking mechanism 13 from rotating to change position; then the second electric push rod 45 is pushed out, the hook plate 454 is inserted into the second groove 72, and then the second electric push rod 45 is controlled to slide along the through groove 421 by rotating the second adjusting disc 43 controlled by the first motor 44, so that the hook plate 454 hooks the support ring 6, and then the second electric push rod 45 is retracted and reset, and the support ring 6 overcomes the block of the stop block 711 to reset the stop block to continue to cooperate with the screw rod 73 to retract the support ring 6; at this time the hook plate 454 is disconnected from the hooking of the support ring 6 in the first groove 1331; in this process, the second adjusting disc 43 rotates to push the second electric push rod 45 to slide along the through groove 421 through the arc-shaped groove 431 to realize the adjustment of the second electric push rod 45; the limiting plate 453 ensures the stability of the second electric push rod 45, and the square block 452 arranged in the through groove 421 ensures that the second electric push rod 45 will not rotate during use, and can stably hook the support ring 6.

[0062] Then the support ring 6 is continuously expanded in diameter by the jacking of the jacking plate 133, and the jacking plate 133 not only jacks the damaged and deformed inner wall of the pipeline to restore, but also drives the support ring 6 to expand in diameter to fit the repaired pipeline inner wall to realize support, and the support ring 6 supports the repaired area to prevent it from being damaged by the damaged and deformed area of the pipeline when the inner liner is pulled into the pipeline.
