Description

Technical Field

[0001] This utility model relates to the field of concrete curing technology, specifically to a steam curing device for manufactured sand concrete. Background Technology

[0002] Steam curing of concrete is a curing method that accelerates the hardening of concrete through steam heating. It promotes the hydration reaction of cement by providing specific humidity and temperature conditions, thereby accelerating the hardening and strength gain of the concrete. According to existing technology, such as the steam curing device for concrete pipe piles disclosed in Chinese patent document CN213260132U, an air outlet pipe is installed between the air outlet and the air outlet chamber of the air heating mechanism, and a circulating fan is installed on the air outlet pipe or return pipe. This ensures smooth airflow inside the steam curing tank, and simultaneously removes moisture from the air during the circulating heating process, keeping the air dry and improving steam curing efficiency.

[0003] According to its publicly available technical solutions, the internal space of the steam curing equipment used for manufactured sand concrete pile components in the existing technology is fixed. Therefore, when a small number of concrete piles are placed, high-temperature steam is still needed to fill the internal space. As a result, the utilization rate of steam is not high. In addition, the distance between each pile and the steam injection position is different, which leads to certain differences in the actual effect of steam curing. Utility Model Content

[0004] To address the shortcomings of existing technologies, the purpose of this invention is to provide a steam curing device for manufactured sand concrete, thereby solving the problems mentioned in the background art. This invention is used for steam curing concrete piles, and the placement and insertion process for each pile is simple, efficient, and highly accurate. It delivers corresponding high-temperature steam according to the specific number of piles placed, resulting in higher utilization of high-temperature steam. Furthermore, each pile is steam cured through an independent steam delivery channel, ensuring that the steam curing effect of each pile is consistent.

[0005] To achieve the above objectives, this utility model is implemented through the following technical solution: a steam curing device for manufactured sand concrete, comprising a steam curing device body, the steam curing device body including a box, a steam curing tank, a pushing bracket, and a lifting mechanism, a cover plate hinged to one side of the box, multiple steam curing tanks opened inside the box, a placement plate welded to the bottom front end of the box, a pushing bracket placed on the top of the box, a lifting mechanism installed at the bottom end of the pushing bracket, multiple connecting pipes inserted into the rear end of the box, and each connecting pipe being connected to the interior of a corresponding steam curing tank, and two protruding rods embedded in the inner wall of each steam curing tank.

[0006] Furthermore, the pusher bracket includes a support frame and a guide plate. The guide plate is welded to the bottom surface of the support frame, and a lifting groove is provided on the inner side of the guide plate. A lower hanging plate is welded to the bottom rear end of the support frame.

Detailed Implementation

[0024] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0025] Please see Figures 1 to 6This utility model provides the following technical solution: a steam curing device for manufactured sand concrete, comprising a steam curing device body, the steam curing device body including a box 1, a steam curing tank 3, a pushing support 4, and a lifting mechanism 5. A cover plate 2 is hinged to one side of the box 1. Multiple steam curing tanks 3 are provided inside the box 1. A placement plate 6 is welded to the front bottom of the box 1. The pushing support 4 is placed on the top of the box 1. The lifting mechanism 5 is installed at the bottom end of the pushing support 4. Multiple connecting pipes 27 are inserted into the rear end of the box 1, and each connecting pipe 27 is connected to the interior of a corresponding steam curing tank 3. Two protruding rods 9 are embedded in the inner wall of each steam curing tank 3. This steam curing device is used for steam curing concrete piles.

[0026] When using this utility model, the concrete piles to be steam-cured are directly placed on the placement plate 6 using external handling equipment. Then, the pushing support 4 is activated. With the help of the pushing support 4, the concrete piles are moved to one side of each placed concrete pile in sequence. With the help of the lifting mechanism 5, the concrete piles placed at the bottom are lifted upwards. After being lifted and aligned with the opening end of the steam curing tank 3, the concrete piles are embedded into the steam curing tank 3 for steam curing. During the steam curing process, high-temperature steam is supplied only to the steam curing tank 3 where the concrete piles are placed.

[0027] In this embodiment, the pushing bracket 4 includes a support frame 11 and a guide plate 12. The guide plate 12 is welded to the bottom surface of the support frame 11, and a lifting groove 13 is formed on the inner side of the guide plate 12. A lower hanging plate 22 is welded to the bottom of the rear end of the support frame 11. An air pump 25 is screwed to the top of the support frame 11, and a moving wheel 21 is inserted into the bottom of the support frame 11. A guide groove 10 is formed on the top of the housing 1, and the bottom of the moving wheel 21 is embedded in the guide groove 10. One end of the air pump 25 is connected to an external steam generator through a pipe. The cover plate 2 is used to seal the opening end of each steam curing tank 3. Each concrete pile is steam cured through an independent steam delivery channel, and the distance between each pile and the inner wall of the steam curing tank 3 is the same, which can ensure that the steam curing effect of each pile is consistent.

[0028] Specifically, since the spacing between each steam curing tank 3 is the same and the internal dimensions are also the same, after the concrete pile is placed inside the steam curing tank 3 by means of the pushing and lifting mechanism 5, the concrete pile will be supported by the bottom protruding rod 9. Therefore, it can be ensured that there is a gap between the side of the concrete pile and the inner wall of the steam curing tank 3. This gap can ensure that the high temperature steam injected at the rear end can fully contact any area around the concrete pile, and the position of each concrete pile and the steam injection at the rear end are consistent, so as to improve the uniformity of the steam curing effect of each batch of concrete piles.

[0029] In this embodiment, the lifting mechanism 5 includes a push rod 14, a vertical hydraulic rod 15, and a horizontal hydraulic rod 18. The top end of the vertical hydraulic rod 15 is screwed to the bottom of the support frame 11, and the push rod 14 is screwed to the bottom end of the vertical hydraulic rod 15. The rear end of the push rod 14 is inserted into the interior of the lifting groove 13. One end of the push rod 14 is integrally formed with an end plate 17, and the horizontal hydraulic rod 18 is inserted in the middle of the end plate 17. The horizontal hydraulic rod 18 is used to push the concrete pile on the placement plate 6. One end of the placement plate 6 is screwed with a motor 8. The output end of the motor 8 is inserted with a lead screw 16. The bottom of the push rod 14 is integrally formed with a movable seat 19, and the lead screw 16 passes through the threaded hole at the bottom of the movable seat 19. The side of the movable seat 19 has a groove 7, and the lifting groove 20 is integrally embedded in the groove 7. Each pile only needs to be pushed onto the placement plate 6, and then it can be aligned with each part of the steam curing tank 3 by means of the lifting mechanism 5. Then, the pile can be pushed into the steam curing tank 3 by the pushing structure, making the whole placement and insertion process simple, efficient and highly accurate.

[0030] Specifically, after starting the motor 8, the motor 8 drives the lead screw 16 to rotate. The lead screw 16, in conjunction with the moving seat 19, can drive the lifting groove 20 on one side to move along the groove 7. Since each concrete pile is supported by the placement plate 6 on the surface of the groove 7, the lifting groove 20 can move directly to the bottom of the concrete pile at the end. At this time, the vertical hydraulic rod 15 is activated to pull the push rod 14 at the bottom to lift it. The concrete pile can be lifted with the help of the lifting groove 20. With the horizontal drive effect of the motor 8, each concrete pile can be aligned with the opening end of the corresponding steam curing tank 3. At this time, the horizontal hydraulic rod 18 is activated to push the concrete pile from the end into the steam curing tank 3 for the subsequent steam curing process.

[0031] In this embodiment, a lifting pipe 28 is inserted into the rear end of the connecting pipe 27. A spring 30 is welded to one end of the lifting pipe 28, which is hidden inside the connecting pipe 27, and an inclined plate 29 is welded to the other end. One end of the air pump 25 is connected to a steam pipe 26, and a plug-in plate 23 is welded to the inner side of the bottom end of the lower hanging plate 22. The plug-in plate 23 has docking holes 24 at both its top and bottom. After translational movement, the plug-in plate 23 aligns sequentially with the openings at the ends of each lifting pipe 28 through the docking holes 24. The air pump 25 delivers high-temperature steam along the steam pipe 26 and the interior of the lower hanging plate 22 to the docking holes 24. Multiple steam curing tanks 3 are arranged inside the housing 1, and each steam curing tank 3 is isolated from the others. When steam is injected into each steam curing tank 3, it is connected to the corresponding steam curing tank 3 by a pusher bracket 4 before steam is injected. This allows for the delivery of the corresponding high-temperature steam according to the specific number of piles placed, resulting in higher utilization of the high-temperature steam.

[0032] Specifically, after all the concrete piles have been placed, the motor 8 still controls the movement of the pusher 4, which in turn moves the lower hanging plate 22 and the rear plug-in plate 23. The two connecting pipes 27 on the same vertical line push the end lifting pipes 28 with the spring 30 to ensure that the openings of the lifting pipes 28 are in contact with each other, so that the steam inside the two steam curing tanks 3 will not be discharged under normal conditions. Only after the pusher 4 pushes the plug-in plate 23 against the inclined plate 29 can the two lifting pipes 28 be separated. At this time, by aligning the docking hole with the opening of the two lifting pipes 28, the air pump 25 can inject the high-temperature steam generated outside into the steam curing tank 3 in sequence along the steam pipe 26, the lower hanging plate 22, the docking port, and the connecting pipe 27.

[0033] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. It is obvious to those skilled in the art that this utility model is not limited to the details of the above exemplary embodiments, and that it can be implemented in other specific forms without departing from the spirit or basic characteristics of this utility model.

[0034] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
