Description

Technical Field

[0001] This utility model belongs to the field of concrete technology, and in particular relates to a curing box for precast concrete. Background Technology

[0002] Precast concrete refers to assembled concrete components that are prefabricated before installation on the construction site. Common examples include precast concrete floor slabs, concrete box girders for bridges, precast concrete roof trusses for industrial plants, culvert frames, and precast concrete piles for foundation treatment. Insulated boxes are insulated containers used for food delivery. Insulated boxes are classified into different types based on their material, including plastic, foam, metal, and wooden boxes. A curing room is a testing facility that regulates the internal temperature and humidity to cure concrete test blocks, cement test blocks, mortar, insulation materials, coatings, structural adhesives, etc., to ensure they meet testing requirements.

[0003] However, in the curing process of precast concrete bricks, the existing curing boxes cannot ensure that the steam comes into full contact with the outer surface of the precast concrete bricks, resulting in poor curing effect, failure to keep the curing environment in the best condition, and long curing cycle, which affects production efficiency. Utility Model Content

[0004] The purpose of this utility model is to provide a curing box for precast concrete, which solves the problems of existing curing boxes that make it difficult to ensure that steam fully contacts the outer surface of precast concrete bricks during curing, resulting in poor curing effect, inability to keep the curing environment in the best condition, and long curing cycle, which affects production efficiency.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model is a curing box for precast concrete, including a box body, a box door hinged to the front side of the box body, and a moisture-retaining mechanism provided on the left side of the box body;

[0007] The humidification mechanism includes several connecting frames fixedly connected to the inner wall of the box, with a placement plate slidably connected between corresponding two connecting frames. There are three placement plates, arranged in a row inside the box. A diversion box is fixedly connected to the left side of the box, and a conduit is connected to the rear side of the diversion box. The end of the conduit away from the diversion box is connected to an external steam device. Several hollow tubes are connected to the bottom of the diversion box. A sealing box is connected to the left side of the box. The hollow tubes all pass through the interior of the sealing box and are rotatably connected to the sealing box. Several nozzles are opened on the outer wall of the hollow tubes, and the nozzles are all located inside the sealing box.

[0008] Furthermore, each of the hollow tubes has a connecting ring fixedly connected to its outer wall, and each of the connecting rings has a hinge shaft fixedly connected to its bottom. Each of the hinge shafts has a hinge rod rotatably connected to its outer wall.

[0009] Furthermore, a gear is fixedly connected to the outer wall of the hollow tube, a trapezoidal slide rail is fixedly connected to the left side of the box, and a rack is slidably connected to the outer wall of the trapezoidal slide rail, the rack meshing with the gear.

[0010] Furthermore, a motor is fixedly connected to the left side of the housing, and a rotating rod is fixedly connected to the output end of the motor via a coupling.

[0011] Furthermore, a turntable is fixedly connected to the bottom end of the rotating rod, and an eccentric shaft is fixedly connected to the bottom end of the turntable.

[0012] Furthermore, a second hinge rod is rotatably connected to the outer wall of the eccentric shaft, and a second connecting shaft is fixedly connected to the rear end of the rack. The end of the second hinge rod away from the eccentric shaft is rotatably connected to the outer wall of the second connecting shaft.

[0013] This utility model has the following beneficial effects:

[0014] 1. By incorporating a moisturizing mechanism, after precast concrete bricks are placed on multiple placement plates, these plates are slid between corresponding connecting frames. Steam is then introduced into the distribution box via conduits through a steam generator. The steam is divided into multiple streams that flow into multiple hollow tubes and are discharged through multiple nozzles to spray and moisturize the precast concrete bricks. The multiple nozzle design ensures that the steam fully contacts the outer surface of the precast concrete bricks, greatly improving the curing effect and ensuring that environmental conditions remain optimal during the curing process. This not only saves labor costs but also significantly shortens the curing cycle of the precast concrete bricks.

[0015] 2. By incorporating a motor, during the spraying and curing process of precast concrete bricks, the motor can drive the turntable to rotate synchronously. With the cooperation of the eccentric shaft and the second hinge rod, the rack moves back and forth on the outer wall of the trapezoidal slide rail, thereby causing the rack to drive the gear to rotate alternately in both directions. The connecting ring cooperates with the first hinge shaft to make multiple hollow tubes rotate synchronously, allowing the gear to drive multiple hollow tubes to rotate synchronously, expanding the spraying range of multiple hollow tubes, and further improving the efficiency of moisturizing and curing.

[0016] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0026] Please see Figure 1-5 As shown, this utility model is a curing box for precast concrete, including a box body 1, a box door 11 hinged to the front side of the box body 1, and a moisture-retaining mechanism 2 provided on the left side of the box body 1.

[0027] The humidification mechanism 2 includes several connecting frames 21 fixedly connected to the inner wall of the housing 1. A placement plate 22 is slidably connected between corresponding pairs of connecting frames 21. There are three placement plates 22 arranged in a row inside the housing 1. A distribution box 23 is fixedly connected to the left side of the housing 1. A conduit 24 is connected to the rear side of the distribution box 23. One end of the conduit 24, away from the distribution box 23, is connected to an external steam device. Several hollow tubes 25 are connected to the bottom of the distribution box 23. A sealing box 26 is connected to the left side of the housing 1, and all the hollow tubes 25 pass through the sealing box. The interior of the 26 is rotatably connected to the sealed box 26. Several nozzles 251 are opened on the outer wall of several hollow tubes 25. The nozzles 251 are all located inside the sealed box 26. By setting a moisturizing mechanism 2, steam is introduced into the distribution box 23 through the conduit 24 by the steam equipment. The steam is divided into multiple streams and flows into the interior of multiple hollow tubes 25 respectively. It is discharged through multiple nozzles 251 to spray and moisturize the precast concrete bricks. The design of multiple nozzles 251 allows the steam to fully contact the outer surface of the precast concrete bricks, which greatly improves the curing effect of the precast concrete bricks.

[0028] A series of hollow tubes 25 are fixedly connected to the outer walls of several hollow tubes 25. A hinge shaft 271 is fixedly connected to the bottom of each of the several connecting tubes 27. A hinge rod 28 is rotatably connected to the outer wall of each of the several hinge shafts 271. A gear 29 is fixedly connected to the outer wall of the corresponding hollow tube 25. A trapezoidal slide rail 291 is fixedly connected to the left side of the housing 1. A rack 292 is slidably connected to the outer wall of the trapezoidal slide rail 291, and the rack 292 meshes with the gear 29. A motor 293 is fixedly connected to the left side of the housing 1. A rotating rod 294 is fixedly connected to the output end of the motor 293 via a coupling. A turntable 295 is fixedly connected to the bottom end of the rotating rod 294. An eccentric shaft 296 is fixedly connected to the bottom end of the turntable 295. A hinge rod 298 is rotatably connected to the outer wall of the eccentric shaft 296. The rack 292... The rear end is fixedly connected to the second connecting shaft 297. The end of the second hinge rod 298 away from the eccentric shaft 296 is rotatably connected to the outer wall of the second connecting shaft 297. A motor 293 is provided. During the spraying and curing of precast concrete bricks, the motor 293 can drive the 394 and the turntable 295 to rotate synchronously. With the cooperation of the eccentric shaft 296 and the second hinge rod 298, the rack 292 moves back and forth on the outer wall of the trapezoidal slide rail 291, thereby causing the rack 292 to drive the gear 29 to rotate in both directions. The connecting ring 27 cooperates with the first hinge shaft 271 to make multiple hollow tubes 25 rotate synchronously. This allows the gear 29 to drive multiple hollow tubes 25 to rotate synchronously, expanding the spraying range of the multiple hollow tubes 25 and further improving the efficiency of moisturizing and curing.

[0029] A specific application of this embodiment is as follows: By setting up a moisturizing mechanism 2, after the precast concrete bricks are placed on multiple placement plates 22, the multiple placement plates 22 are slid into the corresponding two connecting frames 21. At this time, steam is introduced into the distribution box 23 through the conduit 24 by the steam equipment. The steam is divided into multiple streams and flows into multiple hollow tubes 25 respectively. It is discharged through multiple nozzles 251 to spray and moisturize the precast concrete bricks. The design of multiple nozzles 251 allows the steam to fully contact the outer surface of the precast concrete bricks, which greatly improves the curing effect of the precast concrete bricks and ensures that the environmental conditions during the curing process are always kept in the best state. This not only saves labor costs, but also significantly shortens the curing cycle of the precast concrete bricks.

[0030] By incorporating a motor 293, during the spraying and curing process of precast concrete bricks, the motor 293 can drive 394 and turntable 295 to rotate synchronously. With the cooperation of eccentric shaft 296 and hinge rod 298, rack 292 moves back and forth on the outer wall of trapezoidal slide rail 291, thereby causing rack 292 to drive gear 29 to rotate alternately in both directions. Meanwhile, connecting ring 27 cooperates with hinge shaft 271 to make multiple hollow tubes 25 rotate synchronously, enabling gear 29 to drive multiple hollow tubes 25 to rotate synchronously, expanding the spraying range of multiple hollow tubes 25 and further improving the efficiency of moisturizing and curing.
