Description

Technical Field

[0001] This utility model relates to the field of maintenance equipment technology, specifically to a steam rapid maintenance equipment. Background Technology

[0002] With the acceleration of urbanization and the continuous development of infrastructure construction, the demand for concrete pavement is increasing year by year. The construction quality of concrete pavement directly affects its service life and driving safety. Therefore, how to ensure the construction quality of concrete pavement, especially in the post-construction curing stage, has become an urgent problem to be solved.

[0003] Traditional concrete pavement curing methods primarily rely on natural curing, utilizing the temperature and humidity conditions of the natural environment to allow the concrete to gradually harden and gain strength. However, this method suffers from problems such as long curing periods and inconsistent results. Especially in the low temperatures of winter, the hardening rate of concrete is slow, which not only prolongs the construction period but may also lead to quality problems such as cracking and sandblasting in the concrete pavement.

[0004] To overcome the shortcomings of traditional curing methods, steam curing technology has been widely used in recent years. Steam curing technology accelerates the hydration reaction of concrete by providing steam with a certain temperature and humidity to the surface or interior of the concrete, thereby shortening the curing cycle and improving the strength and durability of concrete pavements.

[0005] However, existing steam curing equipment still has some problems in practical applications. For example, the equipment is complex in structure, cumbersome in operation, has high energy consumption, and low efficiency. These problems not only increase maintenance costs but also reduce maintenance efficiency. Therefore, developing a steam rapid curing device that is simple in structure, easy to operate, and has low energy consumption is of great significance for improving the construction quality and maintenance efficiency of concrete pavements.

The fixed part 501 is connected to the guide pipe 4, and there are two telescopic parts 502. The telescopic parts 502 are slidably disposed within the telescopic parts 502.

[0035] In this embodiment, the mobile trolley 1 is used to transport the entire curing process, improving the ease of handling. The steam generator 2 is used to generate the concrete poured for curing. The steam delivery pipe is used to transport the steam generated by the steam generator 2 to the concrete surface.

[0036] In this embodiment, the steam distribution assembly is used to divert and transport the water vapor output from the steam output pipe 3 to the concrete surface to be cured. The guide pipe 4 is used to continue the longitudinal transport of water vapor, and the diversion pipe 5 is used to divert the water vapor transported vertically by the guide pipe 4 laterally, thereby expanding the effective area of ​​the water vapor and greatly improving the curing efficiency. Furthermore, the diversion pipe 5 is composed of a fixed part 501 and a telescopic part 502. The length of the diversion pipe 5 can be adjusted by extending and retracting the telescopic part 502 on the fixed part 501, thereby facilitating the adjustment of the length of the diversion pipe 5 according to the width of the concrete and greatly improving its curing efficiency.

[0037] Please refer to Figure 5 In some embodiments of this example, the inner sidewall of the fixing part 501 is provided with a guide groove 7, the opening direction of the guide groove 7 is parallel to the central axis of the fixing part 501, and the telescopic part 502 is provided with a slider 8 adapted to the guide groove 7.

[0038] In this embodiment, the guide groove 7 is used to accommodate the slider 8. The opening direction of the guide groove 7 is parallel to the setting direction of the slider 8, which facilitates the sliding of the telescopic part 502 and prevents the telescopic part 502 from rotating and blocking the diversion hole 6.

[0039] Please refer to Figures 1-4 In some embodiments of this example, the above-mentioned diversion pipe 5 is provided with a collection box for accumulating steam. The collection box includes a fixed groove 9 and an extension groove 10 that can be extended and retracted in conjunction with the telescopic part 502. The fixed groove 9 is covered on the fixed part 501, and the extension groove 10 is connected to the end of the telescopic part 502 away from the fixed part 501.

[0040] In this embodiment, the collection box is used to collect the water vapor that rises after impacting the ground, which can effectively reuse the water vapor and facilitate the circulation of water vapor within the collection box area to the concrete surface, greatly increasing its curing efficiency and effect.

[0041] Furthermore, the aforementioned fixing groove 9 is used to form a cover on the fixing part 501 of the diversion pipe 4, and the aforementioned extension groove 10 is used to form a cover on the telescopic part 502, so as to stretch the collection box when the diversion pipe 5 is pulled, thereby improving the efficiency of maintenance.

[0042] Please refer to Figure 1 , Figure 2 and Figure 6 In some embodiments of this example, a steam return pipe 11 is provided between the collection box and the steam generator 2, and the steam return pipe 11 is used to recover the steam in the collection box.

[0043] In this embodiment, the collection box is filled with a large amount of water vapor. When the water vapor overflows through the opening of the collection box, the water vapor in the collection box is recycled through the steam return pipe 11.

[0044] In some embodiments of this example, a cooling box 12 for cooling water vapor is provided on the steam return pipe 11. The cooling box 12 includes a flow distribution chamber 13, a cooling chamber 14, and a liquid collection chamber 15. Multiple air guide pipes 16 are evenly spaced in the cooling chamber 14. The two ends of any air guide pipe 16 are connected to the flow distribution chamber 13 and the liquid collection chamber 15, respectively. The liquid collected in the liquid collection chamber 15 is used to transport to the steam generator 2 for secondary use. A fan 17 is provided on the cooling box 12 to accelerate the gas flow in the cooling chamber 14.

[0045] In this embodiment, the aforementioned steam-water flow pipe is used to recover and cool water vapor to form water, which is then returned to the steam generator 2 for reuse, thus saving energy and protecting the environment. Specifically, the aforementioned cooling box 12 is used to cool the water vapor recovered by the steam return pipe 11 and then form water for output.

[0046] It should be noted that the aforementioned diversion chamber 13 is used to divert the water vapor recovered and transported by the steam return pipe 11, thereby facilitating the cooling of the water vapor by multiple pipes, increasing the heat exchange area of ​​the pressurized water vapor, and greatly improving the heat exchange efficiency. The aforementioned cooling chamber 14 is used to exchange heat on the surface of the gas guide pipe 16, thereby exchanging heat to form water vapor into water that is collected in the liquid collection chamber 15, facilitating the recovery and reuse of the liquid.

[0047] Furthermore, the aforementioned fan 17 is used to accelerate the gas flow in the cooling chamber 14, thereby greatly improving the heat dissipation efficiency. An air outlet is provided at the end of the cooling chamber 14 away from the fan 17.

[0048] Please refer to Figure 1 , Figure 3 and Figure 4 In some embodiments of this example, an anti-detachment mechanism is provided between the fixed groove 9 and the extension groove 10 to prevent the extension groove 10 from falling off. The anti-detachment mechanism includes a boss 19 provided in the fixed groove 9 and a limiting platform 18 provided in the extension groove 10. The limiting platform 18 can abut against the boss 19.

[0049] In this embodiment, the aforementioned anti-detachment mechanism is used to prevent the separation of the fixing groove 9 and the extension groove 10. Specifically, when the extension groove 10 is pulled apart from the fixing groove 9, the collection box reaches its maximum length when the limiting platform 18 abuts against the boss 19.

[0050] Please refer to Figure 1 and Figure 2 In some embodiments of this example, the steam output pipe 3 and the flow guide pipe 4 are connected by a flange 20.

[0051] In this embodiment, the flange connection uses a combination of flange 20, bolts, and gaskets to tightly connect the pipelines, ensuring the interconnectivity of the pipeline system. The flange connection method is flexible, detachable, and reusable, facilitating maintenance and repair.
