Description

Technical Field

[0001] This utility model relates to the field of precast concrete simply supported beam curing technology, and more specifically, to a high-pressure steam curing device for precast concrete simply supported beams. Background Technology

[0002] High-pressure steam curing of concrete is a method of curing concrete using high-pressure steam, designed to accelerate the hardening process and improve its quality. It involves introducing high-pressure steam into a sealed container, creating a high-temperature, high-humidity environment for curing the concrete. This method can significantly accelerate the hardening process of concrete, improving its early strength and durability.

[0003] Existing technology patent CN220313679U discloses a pressurized steam curing device for the production of high-pressure steam concrete blocks. The device includes a base, a steam curing chamber on the base, and an air supply structure that cooperates with the steam curing chamber. The steam curing chamber has a sealed door, an exhaust pipe, symmetrically arranged heating components, and multiple placement positions. A first control valve is installed on the exhaust pipe, and a support unit is installed on each placement position. Multiple positioning seats are provided on the base, and hydraulic cylinders are installed on the positioning seats. The output end of the hydraulic cylinder is connected to the steam curing chamber via a connecting seat. This device allows for high-pressure steam curing of concrete blocks by placing them inside the steam curing chamber. However, its small size and the single location of the air vents at the bottom of the steam curing chamber make it difficult for the steam inside the chamber to quickly and evenly cure the simply supported beams, which are relatively large. Furthermore, the large mass of the simply supported beams makes them inconvenient to place on the support frame inside the steam curing chamber. Therefore, this prior art is not suitable for high-pressure steam curing of precast concrete simply supported beams. Summary of the Invention

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] like Figures 1-3 As shown, the concrete high-pressure steam curing equipment for precast simply supported beams in this embodiment includes a steam curing shed 1, a steam generating device 3, a steam conveying device, and a transport vehicle 8.

[0024] One side of the steam curing shed 1 is equipped with a sealable door 2 that can be opened and closed. A ramp 18 is provided at the bottom of the sealable door 2, and the top of the ramp 18 is flush with the top surface of the bottom plate of the steam curing shed 1. The length of the steam curing shed 1 is at least twice the length of the simply supported concrete beam. A steam generating device 3 is located on the outside of the steam curing shed 1. Specifically, in this embodiment, the steam generating device 3 is installed on the top of the steam curing shed 1, and the steam generating device 3 is equipped with a steam guide pipe 13.

[0025] In this embodiment, the steam conveying device delivers the steam generated by the steam generator 3 to the steam curing shed 1. The steam conveying device includes a first steam conveying pipe 4 and a second steam conveying pipe 5. The first steam conveying pipe 4 is located at the top of the steam curing shed 1, and the second steam conveying pipe 5 is located on opposite side walls of the steam curing shed 1. Both the first steam conveying pipe 4 and the second steam conveying pipe 5 are equipped with multiple jet nozzles 7 on the side facing the middle of the steam curing shed 1. Both the first steam conveying pipe 4 and the second steam conveying pipe 5 are connected to the air guide pipe 13 through a connecting pipe 6, thereby enabling the delivery of steam into the steam curing shed 1 from three directions, thus quickly and uniformly steam curing the simply supported concrete beams inside the steam curing shed 1.

[0026] In this embodiment, a first linear drive mechanism is installed at the top of the steam curing shed 1. The first linear drive mechanism is connected to the first steam delivery pipe 4 and is used to drive the first steam delivery pipe 4 to move back and forth in a direction perpendicular to the first steam delivery pipe 4. Specifically, the first linear drive mechanism consists of two first electric slides 9 horizontally fixed to the top wall of the steam curing shed 1. The two first electric slides 9 are parallel to each other and perpendicular to the first steam delivery pipe 4, and the two first electric slides 9 operate synchronously. A first telescopic rod 11 is provided on the bottom surface of the slider of the first electric slide 9. The first telescopic rod 11 is vertically arranged and its lower end is connected to the first steam delivery pipe 4. By setting the first telescopic rod 11, the first steam delivery pipe 4 can be moved up and down to accommodate simply supported concrete beams of different heights.

[0027] In this embodiment, the second steam delivery pipe 5 is installed on the two side walls adjacent to the sealed door 2 inside the steam curing shed 1. The second steam delivery pipe 5 is horizontally arranged. A second linear drive mechanism is installed on the side wall of the steam curing shed 1 to drive the second steam delivery pipe 5 to move up and down. Multiple jet nozzles 7 are installed on the side of the second steam delivery pipe 5 away from the inner wall of the steam curing shed 1. Specifically, the second linear drive mechanism consists of two second electric slides 10 fixed to the inner side wall of the steam curing shed 1. The two second electric slides 10 are parallel to each other and vertically arranged, and they operate synchronously. A second telescopic rod 12 is installed on the side of the slider of the second electric slide 10 away from the inner wall of the steam curing shed 1. The second telescopic rod 12 is horizontally arranged and connected to the second steam delivery pipe 5. By setting the second telescopic rod 12, the second steam delivery pipe 5 can be moved horizontally to move closer to or away from the simply supported concrete beam inside the steam curing shed 1, thereby adapting to simply supported concrete beams of different widths.

[0028] In this embodiment, the first telescopic rod 11 and the second telescopic rod 12 can be selected as electric cylinders, hydraulic cylinders, or pneumatic cylinders. A steam generating device 3 is installed at the top of the steam curing shed 1, and the steam generating device 3 is equipped with a steam guide pipe 13. Both the first steam delivery pipe 4 and the second steam delivery pipe 5 are connected to a connecting pipe 6. One end of the connecting pipe 6 away from the first steam delivery pipe 4 or the second steam delivery pipe 5 passes through the top wall of the steam curing shed 1 and connects to the steam guide pipe 13. Specifically, the connecting pipe 6 is a flexible hose, and a sealing sleeve 25 is fixedly fitted at the position where the connecting pipe 6 passes through the top wall of the steam curing shed 1. The sealing sleeve 25 is fixed to the top wall of the steam curing shed 1. The sealing sleeve 25 serves two purposes: firstly, to seal the connection between the connecting pipe 6 and the steam curing shed 1; and secondly, to fix the connection between the connecting pipe 6 and the steam curing shed 1.

[0029] Preferably, the air duct 13 is equipped with a pressure relief pipe 20, and the pressure relief pipe 20 is equipped with a first control valve 21 to evenly release pressure and exhaust air, avoiding damage to the simply supported concrete beam. An exhaust pipe 22 is provided on the side of the steam curing shed 1 away from the sealed door 2, and a second control valve 23 is provided on the exhaust pipe 22. A temperature and humidity monitoring device 17 is also installed inside the steam curing shed 1.

[0030] In this embodiment, the transport vehicle 8 is a remotely controllable or remotely controlled transport vehicle 8, which includes a base plate, wheels, and a control box (not shown in the figure). During use, the simply supported concrete beam is hoisted onto the base plate using external hoisting equipment. Preferably, the base plate is provided with multiple support columns 24. Hoisting the simply supported concrete beam onto the support columns 24 effectively reduces the contact area of ​​the bottom surface of the simply supported concrete beam, facilitating curing. To facilitate the entry and exit of the transport vehicle 8, a ramp 18 is provided at the bottom of the sealed door 2.

[0031] The working principle of the high-pressure steam curing equipment for precast simply supported concrete beams in this embodiment is as follows:

[0032] The first steam delivery pipe 4 is installed at the top of the steam curing shed 1, and the second steam delivery pipe 5 is installed on the opposite side walls of the steam curing shed 1, so that steam can be sprayed from three sides inside the steam curing shed 1, thereby enabling rapid and uniform steam curing of the simply supported concrete beam. Furthermore, a transport vehicle 8 is used to hoist the simply supported concrete beam onto the transport vehicle 8 using external lifting equipment. The transport vehicle 8 is then moved into the steam curing shed 1, facilitating the transport of the heavy simply supported concrete beam into the steam curing shed 1 for curing. After curing, the simply supported concrete beam is transported out using the transport vehicle 8.

[0033] In another embodiment, the steam conveying device further includes a third steam conveying pipe 14, and the length of the steam curing shed 1 is at least twice the length of the simply supported concrete beam. The first steam conveying pipe 4 and the second steam conveying pipe 5 are both located inside the steam curing shed 1 on the side away from the sealed box door 2. A third linear drive mechanism is located on the top side of the steam curing shed 1 near the sealed box door 2, and the third linear drive mechanism is connected to a lifting mechanism. The lifting mechanism is connected to the end of the third steam conveying pipe 14 near the sealed box door 2. The third steam conveying pipe 14 is connected to the air guide pipe 13 through a connecting pipe 6 and has a jet nozzle 7 on its outer side.

[0034] Specifically, the third linear drive mechanism is the third electric slide 15, the length of which is parallel to the length of the steam curing shed 1. The lifting mechanism is the third telescopic rod 16, which is vertically arranged and its upper and lower ends are respectively connected to the slider of the third electric slide 15 and the third steam delivery pipe 14. Two rows of jet nozzles 7 are symmetrically arranged on the outer side of the third steam delivery pipe 14.

[0035] By setting up a third steam delivery pipe 14, it is possible to quickly steam cure the interior of the simply supported concrete beam. In use, the third steam delivery pipe 14 is lowered by the third telescopic rod 16, and then the third electric slide 15 drives the third steam delivery pipe 14 to move horizontally to the inside of the simply supported concrete beam, and steam is ejected through the jet nozzle 7 on the outside of the third steam delivery pipe 14.

[0036] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
