Description

Technical Field

[0001] This utility model relates to the field of concrete product curing, and in particular to an automatic steam curing tank for railway sleepers. Background Technology

[0002] As a crucial piece of transportation infrastructure, the quality and performance of concrete railway sleepers are of paramount importance. The steam curing process, which involves steam curing the sleepers using specialized equipment, enhances their strength and durability, playing a vital role in improving the quality and strength of concrete components.

[0003] Chinese patent application number 201721106728.8 discloses a steam curing tank for short railway sleepers. This patent mainly comprises several spaced-apart tanks, each containing a curing chamber equipped with a temperature sensor. Each tank has a U-shaped water seal groove at the top of its four side walls. Each tank has a cover with an edge extending downwards into the U-shaped water seal groove. A steam pipe runs longitudinally along the bottom of the tank, connecting to a main steam pipe outside the tank via branch pipes. Each branch pipe is equipped with a solenoid valve and a pneumatic control valve, and the main steam pipe has a main control valve. This patent can shorten the curing cycle of short railway sleepers, increase the turnover rate of steel molds, control the temperature of the steam curing tank, and add steam as needed, effectively maintaining the temperature of the curing tank.

[0004] However, the aforementioned patent involves stacking three rows of steel molds inside each pool for steam curing and using a bottom-point steam diffusion method. The overlapping surface formed by the stacked steel molds may block the steam diffusion and contact, resulting in uneven steam coverage on the sleeper surface. At the same time, due to the upward diffusion of steam, the steam contact time of different layers of steel molds varies, which can easily cause temperature differences and affect the curing quality. Utility Model Content

[0005] This invention provides an automatic steam curing tank for railway sleepers, which can solve the problem of uneven steam coverage on the surface of railway sleepers in existing automatic steam curing tanks, which easily leads to temperature differences and affects the quality of curing.

[0006] An automatic steam curing tank for railway sleepers includes a tank body and a cover on top of the tank body. The tank body is provided with a plurality of support components for supporting railway sleeper steel molds. The support components include a plurality of placement components arranged symmetrically at equal intervals. The placement assembly includes a frame fixed to the bottom wall of the pool and multiple linkage components arranged longitudinally at equal intervals on the frame. The linkage components include a support plate movably connected inside the frame, a fixed plate fixed to the frame, a top rod slidably connected to the fixed plate, and a connecting rod rotatably connected to the top of the support plate and located below the fixed plate. The top end of the connecting rod is rotatably connected to the bottom end of the top rod, wherein the inclination angle of the bottom support plate is smaller than the inclination angle of the other support plates. The pool body is also equipped with a steam transmission assembly, which includes multiple second steam outlet pipes located between the two frames and multiple first steam transmission branch pipes located between the two support components.

[0007] Preferably, the linkage component further includes a first rotating shaft fixed to the support plate and a limiting rod fixed to the frame, wherein the first rotating shaft rotates on the frame and the limiting rod is located above the support plate.

[0008] Preferably, each of the plurality of adjacent second steam outlet pipes is connected to a second steam transmission branch pipe at one end, and the top of the horizontal section of the first steam transmission branch pipe is uniformly connected to a plurality of first steam outlet pipes.

[0009] Preferably, the steam transmission assembly further includes a main steam pipe fixed to the side wall of the pool and two steam transmission headers connected to the main steam pipe. Each of the first steam transmission branch pipes is connected to one of the steam transmission headers, and each of the second steam transmission branch pipes is connected to the corresponding steam transmission header.

[0010] Preferably, the second steam outlet pipe is located between two adjacent sleepers.

[0011] Preferably, the pool body is further provided with a drainage assembly, which includes a main drainage channel located in the middle of the bottom wall of the pool body, a plurality of auxiliary drainage channels located on the bottom wall of the pool body and perpendicular to the main drainage channel, and a drain pipe fixed on the side wall of the pool body and located on one side of the main drainage channel.

[0012] Preferably, a sealing ring is fixedly provided at the bottom of the cover, and a hook is fixedly provided at the top of the cover.

[0013] Preferably, each of the first and second steam outlet pipes is equipped with a check valve.

[0014] Preferably, the main drainage trough is inclined toward the drain pipe, and each of the auxiliary drainage troughs is inclined toward the main drainage trough.

[0015] Preferably, the support plate is divided into two asymmetrical weight sides with the first pivot as the center, and the weight of the support plate on the side closer to the connecting rod is greater than that on the other side.

[0016] This utility model provides an automatic steam curing tank for railway sleepers, which has the following beneficial effects: 1. When the sleeper steel mold is hoisted and placed on the bottom support plate, the sleeper steel mold contacts the support plate and rotates horizontally. The rotation of the support plate drives the connecting rod, pushing the top rod to slide upwards along the fixed plate. The movement of the top rod is transmitted to the upper support plate, causing it to rotate and adjust its angle. The distance between the support plates is less than the length of the sleeper steel mold, facilitating subsequent placement of the sleeper steel mold. By setting support plates of different heights to support the sleeper steel mold, when the sleeper steel molds are stacked inside the pool, steam can easily penetrate the gaps between the stacked sleeper steel molds, ensuring that all surfaces of the sleeper steel mold are covered by steam and improving the uniformity of steam curing.

[0017] 2. Steam originates from the main steam pipeline and is distributed through the steam header to the first and second steam branch pipes. It is then ejected through the first and second steam outlet pipes. The first steam outlet pipe evenly diffuses steam laterally onto the sleeper mold, while the second steam outlet pipe evenly diffuses steam onto the top and bottom surfaces of the sleeper mold. The synergistic effect of the first and second steam outlet pipes ensures that the entire surface of the sleeper mold is in contact with steam for steam curing, resulting in more uniform heating and curing and better maintenance.

[0020] The specific embodiments of this utility model are described in detail below, but it should be understood that the protection scope of this utility model is not limited to the specific embodiments.

[0021] like Figures 1 to 6 As shown in the figure, an automatic steam curing tank for railway sleepers provided in this embodiment of the utility model includes a tank body 1 and a cover body 2 disposed on the top of the tank body 1. The tank body 1 contains multiple support components for supporting railway sleeper steel molds. Each support component includes multiple symmetrically arranged placement components. Each placement component includes a frame 3 fixed to the inner bottom wall of the tank body 1 and multiple longitudinally equidistantly arranged linkage components on the frame 3. Each linkage component includes a support plate 5 movably connected inside the frame 3, a fixing plate 8 fixed to the frame 3, a top rod 9 slidably connected to the fixing plate 8, a connecting rod 7 rotatably connected to the top of the support plate 5 and located below the fixing plate 8, a first rotating shaft 4 fixed to the support plate 5, and a limiting rod 6 fixed to the frame 3. The top end of the connecting rod 7 is rotatably connected to the bottom end of the top rod 9. A through groove is provided inside the fixing plate 8 for the movement of the top rod 9. The first rotating shaft 4 rotates on the frame 3, and the limiting rod 6 is located above the support plate 5. Two limiting rods 6 form a group, each used to limit the rotation angle of the support plate 5. The support plate 5 is divided into two asymmetrical weight distributions centered on the first pivot 4. The weight of the support plate 5 on the side closer to the connecting rod 7 is greater than that on the other side, causing the support plate 5 to automatically return to its tilted state with the first pivot 4 as the fulcrum. The tilt angle of the bottom support plate 5 is smaller than that of the other support plates 5, allowing the sleeper steel mold to contact the bottommost support plate 5.

[0022] Under normal circumstances, the support plates 5 are tilted under gravity, allowing the sleeper molds to move freely between them. The bottom support plate 5 has the smallest tilt angle, and the distance between them is less than the length of the sleeper mold. When the sleeper mold is hoisted and placed on the bottom support plate 5, it contacts the support plate 5 and rotates horizontally. The rotation of the support plate 5 causes the connecting rod 7 to move, pushing the top rod 9 to slide upwards along the fixed plate 8. The movement of the top rod 9 is transmitted to the upper support plate 5, causing it to rotate and adjust its angle. The distance between the support plates 5 is less than the length of the sleeper mold, facilitating the placement of subsequent sleeper molds. When it is necessary to remove the sleeper mold, only the top sleeper mold needs to be removed. Each support plate 5 automatically returns to its initial tilted state under gravity, facilitating the removal of the lower sleeper molds.

[0023] By setting support plates 5 of different heights to support the sleeper steel molds, when the sleeper steel molds are stacked inside the pool body 1, steam can easily penetrate the gaps between the stacked sleeper steel molds, so that steam can cover all surfaces of the sleeper steel molds and improve the uniformity of steam curing.

[0024] In some specific implementation plans, such as Figure 2 and Figure 3As shown, the pool body 1 also contains a steam transmission assembly, which includes multiple second steam outlet pipes 15 located between the two frames 3 and multiple first steam transmission branch pipes 12 located between the two support components. Each set of adjacent second steam outlet pipes 15 is connected at one end to a second steam transmission branch pipe 14. Multiple first steam outlet pipes 13 are evenly connected to the top of the horizontal section of the first steam transmission branch pipe 12. A gap is left between the bottom of the first steam transmission branch pipe 12 and the bottom wall of the pool body 1 to ensure the free flow of condensate. Each first steam outlet pipe 13 and second steam outlet pipe 15 is equipped with a one-way valve to seal the steam outlet pipe.

[0025] The second steam outlet pipe 15 is located at both ends of the sleeper steel mold, and the first steam outlet pipe 13 is located on both sides of the sleeper steel mold. After the steam is sprayed out, the two ends and sides of the sleeper steel mold can be evenly contacted with steam for steam curing. Through the synergistic effect of the first steam outlet pipe 13 and the second steam outlet pipe 15, the surface of the sleeper steel mold is in contact with steam for steam curing, resulting in more uniform heating and curing of the sleeper steel mold and better curing effect.

[0026] In some specific implementation plans, such as Figure 2 and Figure 3 As shown, the steam transmission assembly also includes a main steam pipe 10 fixed to the side wall of the pool body 1 and two steam transmission headers 11 connected to the main steam pipe 10. The main steam pipe 10 is connected to an external steam generating device, and the steam transmission headers 11 are fixed to the inner wall of the pool body 1. Each first steam transmission branch pipe 12 is connected to one of the steam transmission headers 11. The first steam transmission branch pipe 12 has an L-shaped structure, and its vertical section is used to connect to the steam transmission header 11. Each second steam transmission branch pipe 14 is connected to a corresponding steam transmission header 11. The second steam transmission branch pipe 14 is located on two opposite inner walls of the pool body 1. The second steam outlet pipe 15 is located between two adjacent upper and lower sleeper steel molds to facilitate steam injection into the area between the upper and lower sleeper steel molds. The first steam transmission branch pipe 12 is located between the left and right sleeper steel molds, and the first steam outlet pipe 13 injects steam laterally into the left and right sleeper steel molds.

[0027] Steam output from the steam generating device is distributed from the main steam pipeline 10 through the steam header 11 to the interior of the first steam branch pipe 12 and the second steam branch pipe 14 to form a uniform steam diffusion structure. Steam is ejected through the first steam outlet pipe 13 and the second steam outlet pipe 15. The first steam outlet pipe 13 uniformly sprays diffused steam laterally onto the sleeper steel mold, and the second steam outlet pipe 15 uniformly sprays diffused steam onto the top and bottom surfaces of the sleeper steel mold.

[0028] Steam curing of concrete sleeper steel formwork components utilizes steam to heat the concrete, causing it to harden within the curing chamber. An integrated temperature control system monitors and controls the temperature within the curing area, typically including temperature sensors and controllers. This is existing technology and will not be elaborated upon further in this application.

[0029] In some specific implementation plans, such as Figure 2 and Figure 3 As shown, the pool body 1 is also equipped with a drainage assembly, which includes a main drainage channel 16 located in the middle of the bottom wall of the pool body 1, multiple auxiliary drainage channels 17 located on the bottom wall of the pool body 1 and perpendicular to the main drainage channel 16, and a drain pipe 18 fixed to the side wall of the pool body 1 and located on one side of the main drainage channel 16. A valve is installed on the drain pipe 18 to control drainage. The main drainage channel 16 is inclined towards the drain pipe 18, and each auxiliary drainage channel 17 is also inclined towards the main drainage channel 16.

[0030] The condensate generated during the steam curing process is accelerated and guided to the main drainage tank 16 inside the auxiliary drainage tank 17 by the inclined surface. The condensate is collected along the inclined main drainage tank 16 and drained after the valve of the drain pipe 18 is opened.

[0031] In some specific implementation plans, such as Figure 1 and Figure 6 As shown, a sealing ring 19 is fixed at the bottom of the cover 2 to ensure that steam does not leak when the cover is closed. A hook 20 is fixed at the top of the cover 2. The bottom of the hook 20 is fixed at four corners and connected to the cover 2. It can be matched with a crane hoist to achieve quick opening and closing.

[0032] To facilitate understanding of the embodiments of this solution by those skilled in the art, the working principle of this solution will now be briefly explained in conjunction with specific application scenarios: Under normal circumstances, the support plates 5 are tilted under gravity, allowing the sleeper steel mold to move freely between them. The bottom support plate 5 has the smallest tilt angle, and the distance between them is less than the length of the sleeper steel mold. When the sleeper steel mold is hoisted and placed on the bottom support plate 5, the sleeper steel mold contacts the support plate 5, causing it to rotate horizontally. The rotation of the support plate 5 drives the connecting rod 7, pushing the top rod 9 to slide upwards along the fixed plate 8. The movement of the top rod 9 is transmitted to the upper support plate 5, causing it to rotate and adjust its angle. The distance between the support plates 5 is less than the length of the sleeper steel mold, facilitating the subsequent placement of the sleeper steel mold.

[0033] Steam output from the steam generating device is distributed from the main steam pipe 10 through the steam header 11 to the first steam branch pipe 12 and the second steam branch pipe 14 to form a uniform steam diffusion structure. Steam is ejected through the first steam outlet pipe 13 and the second steam outlet pipe 15. The first steam outlet pipe 13 uniformly sprays diffused steam laterally onto the sleeper steel mold, while the second steam outlet pipe 15 uniformly sprays diffused steam onto the top and bottom surfaces of the sleeper steel mold. The sleeper steel molds are stacked sequentially inside the pool body 1. After the steam is ejected, it penetrates the gaps between the stacked sleeper steel molds, allowing the ends and sides of the sleeper steel molds to uniformly contact the steam for steam curing. This results in more uniform heating and curing of the sleeper steel molds, leading to better curing effects.

[0034] When it is necessary to remove the sleeper steel mold, simply remove the top layer of sleeper steel mold. Each support plate 5 will automatically return to its initial tilted state under the action of gravity, making it convenient to remove the lower layer of sleeper steel mold.

[0035] The above-disclosed embodiments are only a few specific examples of the present utility model. However, the embodiments of the present utility model are not limited thereto. Any changes that can be conceived by those skilled in the art should fall within the protection scope of the present utility model.
