Description

Technical Field

[0001] This utility model relates to the field of mechanical device technology, and more specifically to a device for preventing cracks in large-volume concrete. Background Technology

[0002] During the construction of large-volume concrete, the cement hydration reaction generates a large amount of heat. Since concrete itself has poor thermal conductivity, the internal temperature rises rapidly, creating a significant temperature difference with the external environment, leading to temperature cracks. Furthermore, during the hardening process, factors such as moisture evaporation and drying shrinkage can also cause shrinkage cracks. These cracks not only affect the integrity and durability of the concrete structure but may also pose a threat to the safety of the building.

[0003] Therefore, how to provide a device for preventing large-volume concrete cracks that effectively reduces concrete temperature, decreases the generation of temperature cracks, and improves the integrity and durability of concrete structures is a problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0004] In view of this, the present invention provides a device for preventing cracks in large-volume concrete that is flexible, mobile, precise in spraying, and height-adjustable.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A device for preventing cracks in large-volume concrete includes a base plate and casters fixedly installed at the four corners below the base plate. A liquid storage tank is fixedly installed above the base plate. A main liquid outlet pipe is provided on the side of the liquid storage tank.

The secondary liquid outlet pipe is fixedly connected to a spraying device. The support platform has a built-in drive mechanism for adjusting the height of the secondary liquid outlet pipe and the spraying device.

[0007] Preferably, a control valve is installed on the main outlet pipe to control the outflow of the maintenance solution, and an inlet pipe is also provided on the other side of the storage tank for adding the maintenance solution.

[0008] Preferably, the main outlet pipe is nested with a secondary outlet pipe, and the diameter of the secondary outlet pipe is slightly smaller than that of the main outlet pipe.

[0009] Preferably, the spraying device includes a main pipe connected to the drive mechanism by a nut and a nozzle fixedly installed in front of the main pipe.

[0010] Preferably, the nozzle of the spraying device is an atomizing nozzle.

[0011] Preferably, the drive mechanism specifically includes a motor and a screw connected to the motor drive shaft.

[0012] Preferably, the screw is designed longitudinally, and a nut on one side of the spray device is screwed onto the screw. The height of the auxiliary liquid outlet pipe and the spray device can be changed through the cooperation of the screw and the nut.

[0013] As can be seen from the above technical solution, compared with the prior art, the present invention discloses a device for preventing cracks in large-volume concrete. Through the cooperation of a liquid storage tank, a main liquid outlet pipe, a secondary liquid outlet pipe and a spraying device, it can achieve precise spraying of the concrete surface, effectively reduce the concrete temperature and reduce the generation of temperature cracks. At the same time, the drive mechanism built into the support platform can adjust the height of the secondary liquid outlet pipe and the spraying device to adapt to the construction needs of concrete at different heights and ensure the spraying effect.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] This utility model discloses a device for preventing cracks in large-volume concrete, comprising a base plate 1 and casters 2 fixedly installed at the four corners below the base plate 1. A liquid storage tank 3 is fixedly installed above the base plate 1. A main liquid outlet pipe 4 is provided on the side of the liquid storage tank 3. The main liquid outlet pipe 4 passes upward through a support platform 5. At the same time, a secondary liquid outlet pipe 6 is nested inside the main liquid outlet pipe 4. The secondary liquid outlet pipe 6 is fixedly connected to a spraying device 7. The support platform 5 has a built-in drive mechanism 8 for adjusting the height of the secondary liquid outlet pipe 6 and the spraying device 7.

[0020] The base plate 1 has a rectangular structure and provides a supporting foundation for the entire device. The casters 2 at the four corners of the base plate 1 include wheels and steering mechanisms connected to the wheel rollers. This structure allows the wheels to rotate freely in multiple directions, improving the flexibility and maneuverability of the overall device. Locking devices are fixedly installed on the wheels to secure the position of the entire device during operation and prevent accidental slippage.

[0021] The storage tank 3 is used to store the maintenance solution. A control valve 401 is installed on the main outlet pipe 4 to control the outflow of the maintenance solution. An inlet pipe 402 is also provided on the other side of the storage tank 3 for adding the maintenance solution.

[0022] The support platform 5 is fixedly installed above the liquid storage tank 3. Specifically, four connecting columns 9 are installed at the four corners of the base plate 1.

Fixed handrails 10 are installed on both sides of the support platform 5 to facilitate users to better control the overall device.

[0023] The main outlet pipe 4, located on the side of the liquid storage tank 3, extends upward through the support platform 5. The main outlet pipe 4 is nested within the auxiliary outlet pipe 6. The diameter of the auxiliary outlet pipe 6 is slightly smaller than that of the main outlet pipe 4, so the auxiliary outlet pipe 6 can extend and retract inside the main outlet pipe 4.

[0024] The auxiliary outlet pipe 6 is fixedly connected to the spraying device 7. The spraying device 7 includes a main pipe 701 connected to the drive mechanism 8 by a nut 803 and a nozzle 702 fixedly installed in front of the main pipe 701. The nozzle 702 of the spraying device 7 is an atomizing nozzle, which can atomize the curing liquid into tiny droplets to improve the curing effect. The main pipe 701 of the spraying device is also fixedly connected to the auxiliary outlet pipe 6, so that the curing liquid inside the storage tank 3 can be evenly sprayed onto the surface of the large-volume concrete through the nozzle 702 of the spraying device 7.

[0025] The drive mechanism 8 is fixedly installed inside the support platform 5, and specifically includes a motor 801 and a screw 802 connected to the motor drive shaft. The screw has the performance characteristics of wear resistance, high temperature resistance, high strength, and the ability to withstand large torque and high speed. The screw 802 is designed longitudinally, and a nut 803 on one side of the spray device 7 is screwed onto the screw 802. The height of the auxiliary liquid outlet pipe 6 and the spray device 7 can be changed through the cooperation of the screw 802 and the nut 803. Specifically, the motor 801 is set to the same rotation speed, and the screw drive system can achieve automatic up and down movement by setting the forward and reverse rotation of the motor 801. The forward and reverse rotation of the motor means that the motor can rotate in two directions: clockwise (forward) and counterclockwise (reverse).

[0026] A control panel 11 is fixedly installed on the top of the support platform 5 to control the operation of the drive mechanism 8 and the control valve 401, ensuring that the device can run automatically according to the preset program. The control panel is equipped with a touch screen to facilitate the operation of the device by the staff.
