Description

Technical Field

[0001] The utility model belongs to the field of concrete cooling, in particular to a cooling system for ultra-large concrete of a bearing platform. Background Art

[0002] As a key structural part that bears and transmits loads in infrastructure such as bridges, the abutment often requires the pouring of large volumes of concrete. Due to its large volume, this concrete will produce a significant hydration heat effect during the pouring and hardening process. Hydration heat is the heat released by the chemical reaction between cement and water, which will cause the internal temperature of the concrete to rise sharply.

[0003] When the temperature inside concrete rises rapidly and differs significantly from the ambient temperature, significant temperature stress is generated. This stress can cause cracks on the surface and inside the concrete. This cracking not only affects the concrete's aesthetics but also reduces its structural strength and durability. Furthermore, temperature stress can damage the concrete's internal microstructure, further weakening its overall performance. Therefore, the concrete needs to be cooled before pouring. Current existing technologies for pouring large volumes of concrete for foundations make it difficult to quickly cool the concrete, circulate and cool the cooling water, and remove the cooling mechanism quickly.

[0004] Therefore, a cooling system for ultra-large volume concrete of the pedestal is proposed, which has the ability to quickly cool the concrete, can recycle and cool the cooling water, and the cooling mechanism can be easily and quickly removed. Utility Model Content

[0005] In order to overcome the problems in the prior art of pouring ultra-large volume concrete for the pedestal, it is inconvenient to quickly cool the concrete, it is difficult to recycle and cool the cooling water, and the cooling mechanism is inconvenient to quickly remove.

[0006] The technical solution of the utility model is as follows: a cooling system for super-large concrete of a foundation, comprising a bearing plate; two first support frames are fixedly connected to the upper end of the bearing plate, a lifting ear is fixedly connected to the upper and lower centers of the bearing plate, a concrete discharge pipe is fixedly connected to the upper end of the concrete discharge pipe, a cooling tank is fixedly connected to the inner wall of the cooling tank, a fixing ring is fixedly connected to the inner wall of the fixing ring, two first connecting blocks are fixedly connected to the inner wall of the fixing ring, a spiral cooling pipe is fixedly connected to one end of the two first connecting blocks close to the center of the cooling tank, a center tube is fixedly connected to the outer wall of the lower end of the two first support frames close to each other, an inner tank is fixedly connected to the outer wall of the lower end of the center tube, a cooling groove is provided on the upper end of the inner tank, and a cooling groove is provided on the lower part of the side wall of the inner tank. The outer wall of the lower end of the inner tank is fixed with a connecting ring, and the outer wall of the connecting ring is fixed with a cooling cylinder. The inner wall of one of the first support frames is fixed with a fixed box, and the inner wall of the fixed box is fixed with a water pump. The side wall of the cooling tank is fixed with a first fixed pipe in a through-type manner. The water pumping end pipe of the water pump is connected to one end of the first fixed pipe located outside the cooling tank. The inner wall of the cooling cylinder is fixed with a second support frame, and the inner wall of the second support frame is fixed with a second fixed pipe. The water outlet end pipe of the water pump is connected to the inner wall of the upper end of the second fixed pipe. The other end of the first fixed pipe is fixed to the inner wall of one end of the spiral cooling pipe, and the other end of the spiral cooling pipe is fixed with a water supply pipe. The water supply pipe passes through the cooling cylinder and the inner tank and extends to the interior of the inner tank.

[0007] Preferably, when in use, the device is hung in a suitable position by a crane, and then an appropriate amount of cooling water is injected into the cooling cylinder. The cooling water will flow into the interior of the inner tank through the through hole, so that the water level submerges the water supply pipe, and the water will flow into the spiral cooling pipe through the water supply pipe, and finally flow into the first fixed pipe. Then the water pump is turned on to pump the water in the first fixed pipe to the interior of the second fixed pipe, and the water will circulate. Since the cooling water flows in the spiral cooling pipe, the heat on the spiral cooling pipe can be quickly taken away, and then the concrete is placed in the space between the outer wall of the cooling cylinder and the inner wall of the cooling tank. Since the spiral cooling pipe will be immersed in the concrete, it is convenient to quickly cool the concrete. When the device needs to be removed, the hook is hung on the lifting ear by a crane, which can facilitate the removal of the device. This solves the problems in the current prior art that it is inconvenient to quickly cool down the concrete when pouring super-large volume concrete of the foundation, it is difficult to circulate and cool down the cooling water, and the cooling mechanism is inconvenient to quickly remove.

[0008] Preferably, two bearing blocks are fixed to the lower end of the bearing plate, and the two bearing blocks are symmetrical about the concrete discharge pipe. Evenly distributed rollers are rotatably installed on the inner wall of the lower end of the bearing block. When the device is placed on the ground, the bottom ends of multiple rollers contact the ground, which is conducive to the rapid and stable movement of the device.

[0009] Preferably, a balancing assembly is provided on the inner wall of the other first support frame, and the balancing assembly includes a balancing box, a groove, and a weight block; a balancing box is fixedly connected to the inner wall of the other first support frame, a groove is provided on the upper end of the balancing box, and a weight block is movably provided on the inner wall of the groove. When the weight block is placed on the inner wall of the groove and the two lifting ears are lifted by the hook, since the weight of the balancing assembly is roughly equal to that of the fixed box, it is beneficial for the device to maintain balance after being lifted.

[0010] Preferably, a motor is fixed to the upper end of the central tube, the lower end of the output shaft of the motor passes through the upper end of the central tube and is fixed to a rotating rod, and an auger is fixed to the outer wall of the rotating rod. When the motor is turned on, the rotating rod drives the auger to rotate, which can stir the concrete falling in the lower half of the cooling tank and prevent the concrete from segregating.

[0011] Preferably, the upper end surface of the cooling cylinder is located below the upper end surface of the inner tank, and the central axes of the central cylinder, the inner tank and the cooling cylinder are all collinear. Since the through hole connects the interior of the cooling cylinder and the interior of the inner tank, injecting water into the cooling cylinder can allow water to flow into the interior of the inner tank through the through hole. Through the circulation of the water, the cooling water can fully contact with the air in the cooling cylinder and the inner tank to dissipate heat, and the heat will be transferred to the inner tank. The contact between the inner tank and the air will also improve the cooling effect of the water.

[0012] Preferably, a water outlet pipe is fixedly connected to the lower end of the water supply pipe, and the interiors of the water supply pipe and the water outlet pipe are interconnected. The water outlet pipe is located in the space between the inner tank and the cooling cylinder. The water supply pipe can deliver cooling water to the interior of the spiral cooling pipe. The setting of the water outlet pipe can facilitate visual observation of the water level of the cooling water in the cooling cylinder when manually replenishing water. In addition, when the water inlet of the water supply pipe at the cooling trough is blocked, pressurized water is connected to the water outlet pipe to clear the water inlet of the water supply pipe at the cooling trough.

[0013] Preferably, two second connecting blocks are fixedly connected to the outer wall of the inner tank, and one end of the two second connecting blocks away from the center of the inner tank is fixedly connected to the inner wall of the cooling cylinder. The provision of the second connecting blocks can improve the stability of the device.

[0014] Beneficial effects of the utility model:

[0015] 1. Use a crane to hang the device in a suitable position, and then inject an appropriate amount of cooling water into the cooling cylinder. The cooling water will flow into the interior of the inner tank through the through hole, so that the water level submerges the water supply pipe, and the water will flow into the spiral cooling pipe through the water supply pipe, and finally flow into the first fixed pipe. Then turn on the water pump to pump the water in the first fixed pipe to the interior of the second fixed pipe, and the water will circulate. Since the cooling water flows in the spiral cooling pipe, the heat on the spiral cooling pipe can be quickly taken away. Then, concrete is placed in the space between the outer wall of the cooling cylinder and the inner wall of the cooling tank. Since the spiral cooling pipe will be immersed in the concrete, it is convenient to quickly cool the concrete. When the device needs to be removed, the crane is used to hang the hook on the lifting ear, which can facilitate the removal of the device. This solves the problems in the existing technology that it is inconvenient to quickly cool the concrete when pouring ultra-large volume concrete of the foundation, it is difficult to circulate and cool the cooling water, and the cooling mechanism is inconvenient to quickly remove.

[0016] 2. When the device is placed on the ground, the bottom ends of the multiple rollers touch the ground, which is conducive to the rapid and stable movement of the device. When the weight is placed on the inner wall of the groove and the two lifting ears are lifted through the hook, the weight of the balance component and the fixed box is roughly equal, which helps the device maintain balance after being lifted;

[0017] 3. By turning on the motor to make the rotating rod drive the auger to rotate, the concrete falling on the lower half of the cooling tank can be stirred to prevent the concrete from segregating. Since the through hole connects the inside of the cooling cylinder and the inside of the inner tank, injecting water into the cooling cylinder can allow water to flow into the inside of the inner tank through the through hole, which is convenient for efficient heat dissipation of the cooling water. The stability of the device can be improved by setting the second connecting block. BRIEF DESCRIPTION OF THE DRAWINGS

The water supply pipe 25 passes through the cooling cylinder 19 and the inner tank 15 and extends to the interior of the inner tank 15.

[0027] See also Figure 1In this embodiment, two bearing blocks 6 are fixed to the lower end of the bearing plate 1. The two bearing blocks 6 are symmetrical about the concrete discharge pipe 4. The inner wall of the lower end of the bearing block 6 is rotatably mounted with evenly distributed rollers 7.

[0028] See also Figure 1 and Figure 3 In this embodiment, a balancing assembly is provided on the inner wall of another first support frame 2, and the balancing assembly includes a balancing box 201, a groove 202, and a weight 203; the inner wall of another first support frame 2 is fixedly connected to the balancing box 201, and a groove 202 is provided at the upper end of the balancing box 201, and a weight 203 is movably provided on the inner wall of the groove 202.

[0030] See also Figure 4-Figure 6 In this embodiment, the lower end of the water supply pipe 25 is fixedly connected to the water outlet pipe 26, the interiors of the water supply pipe 25 and the water outlet pipe 26 are interconnected, the water outlet pipe 26 is located in the space between the inner tank 15 and the cooling cylinder 19, and the outer wall of the inner tank 15 is fixedly connected to two second connecting blocks 27, and the ends of the two second connecting blocks 27 away from the center of the inner tank 15 are fixedly connected to the inner wall of the cooling cylinder 19.

[0031] When working, first place the weight block 203 on the inner wall of the groove 202. When the two lifting ears 3 are lifted by the hook, the weight of the balance assembly is roughly equal to that of the fixed box 20, which helps the device maintain balance after being lifted. Next, use a crane to hang the device in a suitable position, and then inject an appropriate amount of cooling water into the cooling cylinder 19. The cooling water will flow into the interior of the inner tank 15 through the through hole 17, so that the water level submerges the water supply pipe 25. The water will then flow into the spiral cooling pipe 10 through the water supply pipe 25 and finally flow into the first fixed pipe 22.

Then, concrete is placed in the space between the outer wall of the cooling cylinder 19 and the inner wall of the cooling tank 5. Since the spiral cooling pipe 10 will be submerged in concrete, the cooling water flows inside the spiral cooling pipe 10. As the cooling water is continuously pumped into the second fixed pipe 24 by the water pump 21, the cooling water will flow back into the cooling cylinder 19.

The water inlet at the cooling trough 16 is unblocked, and the cooling water circulates in the cooling cylinder 19, which can quickly remove the heat from the cooling cylinder 19 and cool the concrete on the outer wall of the cooling cylinder 19, thereby facilitating rapid cooling of the concrete. In addition, the temperature of the water in the cooling trough 16 in the inner tank 15 is also transferred to the central cylinder 11. The heat absorption of the central cylinder 11 can improve the heat dissipation effect of the water in the cooling trough 16. The motor 12 is turned on to make the rotating rod 13 drive the auger 14 to rotate, which can stir the concrete in the lower half of the cooling tank 5 to prevent concrete segregation. The concrete is finally discharged downward through the concrete discharge pipe 4.

[0032] When the device needs to be removed, the hook is hung on the lifting lug 3 by a crane, and the device can be easily removed;
