Description

Technical Field

[0001] The utility model belongs to the technical field of concrete construction, and in particular relates to a temperature control device for large-volume concrete construction. Background Art

[0002] In recent years, with the continuous development of construction technology in my country, the use of mass concrete has become more and more common. However, due to the temperature difference between the inside and outside of the concrete caused by the hydration heat of the mass concrete and the slow internal heat dissipation, the concrete surface produces a large tensile stress. When the tensile stress is greater than the tensile strength of the concrete, it will cause the mass concrete to crack during the early curing period. Since the winter temperature in northern my country is relatively low, this problem is more obvious in winter concrete construction in northern my country. The mass concrete construction temperature control device is a device and system specially used to manage and control the temperature changes during the pouring of mass concrete. The mass concrete construction temperature control device monitors the temperature changes inside and on the surface of the concrete in real time through the temperature monitoring system. When the internal temperature of the concrete is detected to be too high, the cooling system is started, and the cooling water circulates in the pre-buried pipes to take away the hydration heat and reduce the concrete temperature; in a low temperature environment, if the temperature is detected to be too low, the heating system is started to increase the concrete temperature through the heating pipes to prevent freezing damage.

[0003] For example, a Chinese utility model patent with announcement number CN218213911U discloses a temperature control device for large-volume concrete construction. By setting an automatically movable device, a water tank and a control chassis, the various structures cooperate with each other to detect the temperature of the concrete, and water is poured according to the detected structure, so that the amount of water poured is proportional to the cooling state of the concrete. The temperature state after watering is detected by a second temperature detection device, and the two are compared before and after, so as to judge the state of the temperature before and after, so as not to affect the solidification time and use state of various parts of the concrete in the later stage.

[0004] However, when the device is used to water large-volume concrete, uneven watering of the large-volume concrete may occur, resulting in poor temperature control effect of the large-volume concrete.

[0005] In summary, there is a need for a large volume concrete temperature control device that can achieve uniform temperature control. Utility Model Content

[0037] In an embodiment of the present application, the implementation principle of a temperature control device for mass concrete construction is as follows: The device controls the temperature of the erected mass concrete. First, when adjusting the spraying range of the device according to the width of the mass concrete, the second helical gear 17 is rotated first, so that the second helical gear 17 drives the long rod 15 to rotate through the first helical gear 16. The long rod 15 drives two symmetrical lead screws 11 to rotate through two synchronous belts, so that the two threaded cylinders 13 move horizontally, thereby causing the blocking plate 14 to block the connection between some nozzles 18 and the connecting pipe 10, thereby reducing the spraying range of the device, enabling the device to adapt to mass concrete of different width sizes, and improving the applicable range of the device.

[0038] When adjusting the spraying range according to the height of the mass concrete, the adjusting lead screw 29 is rotated, so that the adjusting block 23 moves along the adjusting lead screw 29, thereby changing the range of the horizontal reciprocating movement of the connecting rod 24 driving the connecting plate 25, and further changing the range of the deflection of the toothed plate 20 driving the gear 19, so that the reciprocating spraying range of the nozzle 18 is adapted to the height of the mass concrete, and the applicable range of the device is improved.

[0039] After the device is adjusted, the pumping pump 7 is started, so that the water in the water tank 2 flows into the interior of the long cylinder 12 through the water supply pipe 8, the confluence pipe 9 and the connecting pipe 10, and then the water is sprayed onto the surface of the mass concrete through the nozzles 18. The motor 22 is started, so that the turntable 21 rotates, thereby causing the turntable 21 to drive the connecting plate 25 to perform a reciprocating movement through the connecting rod 24, so that the toothed plate 20 performs a reciprocating movement horizontally along the slide rail 28. The gear 19 is affected by the toothed plate 20 and starts to perform a reciprocating deflection movement, so that the long cylinder 12 drives the nozzle 18 to perform a reciprocating deflection movement, thereby realizing uniform watering of the surface of the mass concrete and making the effect of temperature control of the mass concrete better.
