A heating curing device for concrete

Abstract

This invention discloses a heating and curing device for concrete, belonging to the field of concrete curing technology. It includes a device shell with a first and second flap on its front surface. A rotating buckle is provided on the first flap. A water collection tank is located at the bottom of the shell, and a water inlet pipe is located at the top. This invention utilizes a built-in temperature adaptive adjustment structure. When the air bladder inside the fixed box expands due to heat, it pushes a lifting plate to slide along the fixed box. The angle of the connecting rod is adjusted via a transmission rod and crossbar, thereby pushing the sliding baffles along a fixed track, reducing the distance between the sliding baffles and decreasing the steam flow. When the temperature decreases, the air bladder contracts, and the telescopic spring pulls the lifting plate back to its original position, increasing the distance between the sliding baffles and increasing the steam flow. This achieves automatic and constant temperature control inside the device, avoiding problems such as concrete cracking and insufficient strength caused by excessively high or low temperatures, significantly improving curing quality.

Description

Technical Field

[0001] This invention belongs to the field of concrete curing technology, specifically referring to a heating curing device for concrete. Background Technology

[0002] After concrete is poured and formed, it requires scientific heat curing to control internal temperature changes, promote full cement hydration, and prevent shrinkage cracks caused by excessive temperature gradients and rapid moisture loss. This ensures the strength, density, and durability of the concrete. Especially in low-temperature environments, high humidity conditions, or large-volume concrete pouring scenarios, the effectiveness of heat curing directly determines the quality of the concrete components. Improper curing can easily lead to defects such as surface sanding, internal looseness, and cracks, reducing the load-bearing capacity and service life of the concrete structure.

[0003] Currently, existing concrete heating and curing devices still have many technical shortcomings, making it difficult to meet the needs of efficient, precise, and convenient curing. Specifically: First, temperature control accuracy is low. Most devices use a single steam introduction method and lack an automatic adjustment structure, making it impossible to adjust the steam introduction in real time according to internal temperature changes. This easily leads to excessively high or low temperatures, resulting in unstable concrete curing quality. Second, curing uniformity is poor. Concrete components are mostly fixed, leading to uneven contact between steam and the component surface, easily causing inadequate curing in certain areas and uneven temperature distribution, which in turn causes inconsistent strength across the component. Third, operation convenience is lacking. The opening and closing process, as well as the placement and removal of concrete components, are cumbersome, lacking flexible opening and closing structures. Furthermore, some devices are bulky, inconvenient to assemble and disassemble, and have limited ability to adapt to concrete components of different sizes. Fourth, wastewater treatment is not standardized. Condensate generated after steam liquefaction tends to accumulate inside the device and cannot be collected and discharged in a timely manner. This not only affects the humidity control inside the device but may also cause the bottom of the concrete components to become damp and sandy. In addition, the random discharge of condensate will also cause environmental mess. Fifth, the structural stability is insufficient. Concrete components are prone to shaking and tipping after placement, lacking reliable support and fixing structures. Moreover, the internal transmission components of the device are prone to jamming, affecting the continuity of curing operations. Summary of the Invention

[0004] In view of the above situation and to overcome the shortcomings of the prior art, the present invention provides a heating curing device for concrete, which effectively solves the problems currently on the market.

[0005] The technical solution adopted by this invention is as follows: This invention proposes a heating and curing device for concrete, including a device shell. The front surface of the device shell is provided with a first flap and a second flap. The first flap is provided with a rotating buckle. A water collection tank is provided at the bottom of the device shell. A water inlet pipe is provided at the top of the device shell. An air inlet pipe is installed on the device shell. A fixed track is installed on the inner surface of the device shell. A sliding baffle is provided between the fixed tracks. A connecting rod is provided on the sliding baffle. One end of the connecting rod is connected to a crossbar. A transmission rod is provided on the crossbar. A fixed box is provided on the inner surface of the device shell. An air bladder is provided inside the fixed box. A lifting plate is provided above the air bladder. A telescopic spring connects the lifting plate and the fixed box.

[0006] Furthermore, a mounting plate is provided on the bottom surface inside the device housing, a rotating placement disk is mounted on the mounting plate, a driven gear is mounted on the rotating placement disk, a drive rack is provided on one side of the driven gear, a cylinder is provided on the device housing, and a connecting bracket is connected between the drive racks.

[0007] Furthermore, the bottom surface inside the device housing is mesh-like, the first flap and the second flap are symmetrically arranged on the front surface of the device housing, and both the first flap and the second flap are rotatably connected to the device housing. The rotating buckle is rotatably connected to the first flap, and the water collection tank is detachably connected to the device housing.

[0008] Furthermore, the water inlet pipes are symmetrically arranged at the top of the device housing, and the water inlet pipes penetrate and are fixedly connected to the device housing. The air inlet pipes are symmetrically arranged on the device housing, and the air inlet pipes penetrate and are fixedly connected to the device housing.

[0009] Furthermore, the fixed tracks are symmetrically arranged on the inner surface of the device housing and are fixedly connected to the device housing; the sliding baffles are symmetrically arranged between the fixed tracks and are slidably connected to the fixed tracks.

[0010] Furthermore, one end of the connecting rod is rotatably connected to the sliding baffle, both ends of the crossbar are rotatably connected to the other end of the connecting rod, and one end of the transmission rod is fixedly connected to the crossbar.

[0011] Furthermore, the fixed box is fixedly connected to the inner surface of the device housing, the transmission rod passes through and is slidably connected to the fixed box, the lifting plate is fixedly connected to the transmission rod and is slidably connected inside the fixed box, one end of the telescopic spring is fixedly connected to the fixed box, and the other end of the telescopic spring is fixedly connected to the lifting plate.

[0012] Furthermore, the mounting plate is detachably connected to the housing of the device, the rotating placement disk is rotatably connected to the mounting plate, and the driven gear is fixedly connected to the rotating placement disk.

[0013] Furthermore, the drive rack is through and slidably connected, and the drive rack meshes with the driven gear.

[0014] Furthermore, the cylinder has a detachable connecting device housing, the connecting bracket is fixedly connected to the drive rack, and the connecting bracket is fixedly connected to the output end of the cylinder.

[0015] The beneficial effects achieved by the present invention using the above structure are as follows:

[0016] (1) The device has a built-in temperature adaptive adjustment structure. When the air bladder in the fixed box expands due to heat, it can push the lifting plate to slide along the fixed box. The angle of the connecting rod is adjusted by the transmission rod and the cross rod, which in turn pushes the sliding baffle to move along the fixed track, reducing the distance between the sliding baffles and reducing the amount of steam entering. When the temperature drops, the air bladder contracts, the telescopic spring pulls the lifting plate to reset, the distance between the sliding baffles increases, and the amount of steam entering increases, so as to realize the automatic constant control of the internal temperature of the device, avoid concrete cracks and insufficient strength caused by excessively high or low temperatures, and significantly improve the curing quality.

[0017] (2) The device is equipped with a rotating placement plate. The cylinder drives the connecting bracket to move the drive rack back and forth. The drive rack meshes with the driven gear to drive the rotating placement plate and the concrete component above it to rotate back and forth, so that all surfaces of the concrete component can be evenly contacted with steam, avoiding the problems of inadequate local curing and unbalanced temperature distribution, ensuring that the hydration reaction of the concrete component is sufficient, improving the overall strength, density and durability of the component, and reducing local defects.

[0030] An installation plate 17 is provided on the bottom surface inside the device housing 1. A rotating placement disk 18 is installed on the installation plate 17. A driven gear 19 is installed on the rotating placement disk 18. A drive rack 20 is provided on one side of the driven gear 19. A cylinder 21 is provided on the device housing 1. A connecting bracket 22 is connected between the drive racks 20.

[0031] The bottom surface inside the device housing 1 is mesh-like. The first flap 2 and the second flap 3 are symmetrically arranged on the front surface of the device housing 1, and both the first flap 2 and the second flap 3 are rotatably connected to the device housing 1. The rotating buckle 4 is rotatably connected to the first flap 2. The water collection tank 5 is detachably connected to the device housing 1.

[0032] Water inlet pipes 6 are symmetrically arranged on the top of the device housing 1. Water inlet pipes 6 pass through and are fixedly connected to the device housing 1. Air inlet pipes 7 are symmetrically arranged on the device housing 1. Air inlet pipes 7 pass through and are fixedly connected to the device housing 1.

[0033] Fixed rails 8 are symmetrically arranged on the inner surface of the device housing 1 and are fixedly connected to the device housing 1. Sliding baffles 9 are symmetrically arranged between the fixed rails 8 and are slidably connected to the fixed rails 8.

[0034] One end of the connecting rod 10 is rotatably connected to the sliding baffle 9, and both ends of the crossbar 11 are rotatably connected to the other end of the connecting rod 10, and one end of the transmission rod 12 is fixedly connected to the crossbar 11.

[0035] The fixed box 13 is fixedly connected to the inner surface of the device housing 1. The transmission rod 12 passes through and is slidably connected to the fixed box 13. The lifting plate 15 is fixedly connected to the transmission rod 12 and is slidably connected inside the fixed box 13. One end of the telescopic spring 16 is fixedly connected to the fixed box 13, and the other end of the telescopic spring 16 is fixedly connected to the lifting plate 15.

[0036] Mounting plate 17 is detachably connected to housing 1, rotating placement plate 18 is rotatably connected to mounting plate 17, driven gear 19 is fixedly connected to rotating placement plate 18.

[0037] The drive rack 20 is slidably connected through and meshes with the driven gear 19.

[0038] The cylinder 21 is detachably connected to the housing 1 of the connecting bracket 22, which is fixedly connected to the drive rack 20 and is also fixedly connected to the output end of the cylinder 21.

[0039] In practical use, the concrete that needs to be heated and cured is placed on the rotating placement plate 18. If the height of the rotating placement plate 18 is too high or unstable, a simple reinforcement method can be used to fix the concrete on the rotating placement plate 18.

[0040] The water pipe and air pipe are connected to the water inlet pipe 6 and air inlet pipe 7 respectively. Steam is introduced into the interior of the device shell 1 through the air inlet pipe 7 to increase the temperature inside the device shell 1. Water is sprayed into the concrete inside the device shell 1 through the water inlet pipe 6 to prevent the concrete from drying and cracking. After the steam inside the device shell 1 is liquefied, it passes through the device shell 1 and enters the water collection tank 5, and is finally discharged through the pipe set on the water collection tank 5. The controller starts the cylinder 21. After the cylinder 21 is started, it drives the drive rack 20 to move back and forth through the connecting bracket 22. As the drive rack 20 moves back and forth, it drives the driven gear 19 to rotate back and forth, thereby causing the rotating placement plate 18 to rotate the concrete block, ensuring that the concrete block is in uniform contact with the steam.

[0041] As the temperature inside the outer casing 1 of the device continues to rise, the airbag 14 installed in the fixed box 13 expands due to heat, causing the lifting plate 15 to slide upward inside the fixed box 13. The lifting plate 15 drives the connecting rod 10 to adjust its angle through the transmission rod 12 and the crossbar 11. While the connecting rod 10 is adjusting its angle, the sliding baffle 9 moves under the push of the connecting rod 10, thereby reducing the distance between the sliding baffles 9 and reducing the amount of steam entering the outer casing 1 of the device. Conversely, the distance between the sliding baffles 9 increases, and the amount of steam increases, ensuring that the temperature inside the outer casing 1 of the device remains stable within a suitable range. The above is the overall working process of the present invention. This step can be repeated for the next use. The actual operation process is very simple and easy to implement.
