Description

Technical Field

[0001] The present invention relates to the technical field of concrete curing, and particularly relates to a concrete curing device capable of uniformly spraying for curing. Background Art

[0002] In the infrastructure construction of expressways, concrete precast piles are often used to enhance the bearing capacity of the foundation. While ensuring the smoothness and comfort of the road, the service life of the road surface is improved.

[0003] After the concrete precast pile is poured, if the climate is hot and the air is dry, and curing is not carried out in time, the water in the concrete precast pile will evaporate too fast, resulting in dehydration. This will cause the cement particles that have formed a gel to not fully hydrate and cannot be transformed into stable crystals, lacking sufficient adhesion. As a result, flaky or powdery peeling will occur on the surface of the concrete precast pile. When the concrete precast pile does not yet have sufficient strength, premature evaporation of water will also cause large shrinkage deformation and dry shrinkage cracks. Therefore, the curing of the concrete precast pile after pouring is very important. Generally, the concrete precast pile is cured by sprinkling water to keep it moist and avoid water loss to achieve the curing purpose.

[0004] Currently, the concrete precast pile is usually cured by spraying water with a nozzle. However, when curing the concrete precast pile, the current curing device needs to place the concrete precast pile on a support. The lower side surface of the concrete precast pile in contact with the support is completely blocked, making it difficult to fully contact with the sprayed water, which affects the progress of the hydration reaction of the concrete in the lower side surface part. Coupled with the fact that the lower side surface bears the entire weight of the concrete precast pile, it is very easy to cause flaky or powdery peeling on the lower side surface of the concrete precast pile, affecting the curing quality of the concrete precast pile. Summary of the Invention

[0005] The embodiment of the present invention provides a concrete curing device capable of uniformly spraying for curing, which can solve the problems existing in the prior art that it is difficult for the lower side surface of the concrete precast pile to fully contact with the sprayed water, affecting the progress of the hydration reaction of the concrete in the lower side surface part, and coupled with the fact that the lower side surface bears the entire weight of the concrete precast pile, it is very easy to cause flaky or powdery peeling on the lower side surface of the concrete precast pile, affecting the curing quality of the concrete precast pile.

[0021] As Figures 1 to 6 shown, a concrete curing device capable of uniformly spraying and curing includes: Two sets of rotary clamping mechanisms are horizontally arranged opposite to each other. Each rotary clamping mechanism includes a fixed ring 2, a rotating ring 3, a first gear 4, a first rack 6, a second rack 7, a first connecting plate 8, a second connecting plate 9, two connecting rods 10, two clamping members, a telescopic device 11 and a driving part. A square hole for the precast concrete pile 1 to pass through is provided inside the rotating ring 3. The rotating ring 3 is rotatably connected to the inner side wall of the fixed ring 2. A first gear 4 is rotatably connected to the side wall of the rotating ring 3. The first gear 4 meshes with a parallel first rack 6 and a second rack 7. The opposite ends of the first rack 6 and the second rack 7 are respectively provided with a first connecting plate 8 and a second connecting plate 9. The first connecting plate 8 and the second connecting plate 9 are respectively connected with a clamping member through a connecting rod 10. A telescopic device 11 fixedly connected to the first connecting plate 8 is arranged on the side wall of the rotating ring 3. The telescopic device 11 is a cylinder, an electric push rod or a hydraulic cylinder. The two sets of rotary clamping mechanisms are used to clamp the two ends of the precast concrete pile 1 and drive it to rotate at a constant speed. A reciprocating motion mechanism is connected to the two sets of rotary clamping mechanisms. The reciprocating motion mechanism is used to drive the two sets of rotary clamping mechanisms to move towards or away from each other. A spraying component, the water outlet direction of the spraying component faces the precast concrete pile 1.

[0022] During specific use, one end of the precast concrete pile 1 passes through the two rotating rings 3 in sequence. Then, control the telescopic ends of the two telescopic devices 11 to contract. The telescopic device 11 drives the connecting rod 10 fixedly connected to it and the first rack 6 to move towards the central axis direction of the rotating ring 3 through the first connecting plate 8. The first rack 6 drives the second rack 7 to move in the opposite direction through the first gear 4. The second rack 7 drives the other connecting rod 10 to move towards the central axis direction of the rotating ring 3 through the second connecting plate 9, so that the two connecting rods 10 drive the two clamping members to move towards each other and clamp on both sides of the precast concrete pile 1. The spraying component sprays water on the precast concrete pile 1. The driving part drives the precast concrete pile 1 to rotate at a constant speed through the rotating ring 3, so that the sprayed water is evenly sprayed on the four surfaces of the precast concrete pile 1.

The U-shaped plate 15 is fixedly connected to the connecting rod 10 on the same side. The rotating roller 16 is rotatably connected to the inside of the U-shaped plate 15.

[0024] Specifically, through the arrangement of the U-shaped plate 15 and the rotating rollers 16, when the rotating rollers 16 move left and right along with the rotating clamping mechanism, the rotating rollers 16 will roll relative to the precast concrete pile 1, which can avoid damaging the contact surface of the precast concrete pile 1 and improve the curing quality of the precast concrete pile 1.

Two mounting plates 5 are respectively arranged on the two lead screw nuts 23.

[0031] Specifically, during the curing process, the second motor 21 rotates in a forward and reverse cyclic manner, driving the bidirectional lead screw 22 to rotate in a forward and reverse cyclic manner. Under the guiding action of the U-shaped base 20, the bidirectional lead screw 22 drives the two lead screw nuts 23 to perform cyclic movements towards and away from each other, so that the parts of the precast concrete pile 1 covered by the two sets of rotary clamping mechanisms are fully exposed, enabling the sprayed water to be evenly sprayed on the surface of the precast concrete pile 1, thereby improving the curing quality of the precast concrete pile 1.

[0033] Specifically, the bellows 24 seals the opening of the U-shaped base 20, preventing the sprayed water from entering the interior of the U-shaped base 20 and causing corrosion of the reciprocating motion mechanism, which is beneficial to extending the service life of the reciprocating motion mechanism.

[0034] Preferably, a protective housing is provided outside the second motor 21 to prevent the sprayed water from entering the second motor 21.

[0035] To achieve the purpose of saving water resources, preferably, the spraying assembly includes a sedimentation tank 25, a water pump 26, a spray pipe 27, and a filter screen 28. The spray pipe 27 is located above the two sets of rotary clamping mechanisms, the sedimentation tank 25 is located below the two sets of rotary clamping mechanisms, the water pump 26 is respectively connected to the sedimentation tank 25 and the spray pipe 27, and the filter screen 28 is detachably connected to the upper end of the sedimentation tank 25.

[0036] Specifically, after the sprayed water is ejected from the spray pipe 27, most of the sprayed water will enter the sedimentation tank 25 after being filtered by the filter screen 28, and after sedimentation in the sedimentation tank 25, it is reused, thus saving water.
