Description

Technical Field

[0001] The present invention relates to the field of temperature control technology, and in particular to a method and device for intelligent temperature control of large-volume concrete. Background Art

[0002] Spray temperature control of large-volume concrete prefabricated parts is an effective temperature control method. It can prevent quality problems such as cracks in prefabricated parts due to excessively high or low temperatures. By spraying water on the surface of the prefabricated parts, the evaporation and heat absorption of water can be used to reduce the surface temperature of the prefabricated parts. At the same time, the penetration of water can make the internal temperature of the prefabricated parts uniform, thereby achieving the purpose of controlling the temperature of the prefabricated parts.

[0003] The spray temperature control of large-volume concrete includes a water supply system, a spray device and a control system. The temperature inside the large-volume concrete precast parts is sensed by the temperature sensor, and the temperature changes of the precast parts are monitored in real time. The controller controls the start and stop of the water pump and the spray intensity of the nozzle according to the signal of the temperature sensor to achieve automatic spray temperature control. In order to spray the bottom of the large-volume concrete, it is elevated by multiple support frames.

[0004] However, the support frame will block the bottom of the large volume of concrete, causing part of the bottom of the concrete to be unable to be sprayed, which not only affects the spraying area of ​​the concrete, but also causes uneven temperature control of the concrete spraying, affecting the temperature control of the concrete.

[0015] On the other hand, the present application provides a method for intelligent temperature control of large volume concrete, which is applied to the above-mentioned intelligent temperature control device for large volume concrete, and the method steps are as follows: S1. Spraying cooling: The motor drives the toothless bevel gear and the whole bevel gear to rotate to transport water, and sprays water on the mass concrete through the upper spray pipe and the lower spray pipe. The temperature sensor inside the mass concrete is used to control the spraying amount so that the temperature of the mass concrete reaches the set value; S2, Adaptive buffer: Since the temperature sensor is located inside the mass concrete, it takes a certain amount of time for the sprayed water to penetrate into the mass concrete. Through the periodic meshing of the missing bevel gear and the full bevel gear, the water is given time to penetrate so that the water temperature can affect the position of the temperature sensor inside the mass concrete. S3, avoidance spraying: the motor drives the driving shaft and the elliptical disk to rotate, so that the alternating plate reciprocates, and the alternating plate moves with the frame lever, so that the two alternating plates in a group move in opposite directions to replace the upper support plate located at the bottom of the mass concrete, so as to avoid the upper support plate continuously covering the bottom of the mass concrete; S4, positioning support: positioning the lower support plate by means of a spring sheet, and using the bayonet fit between the spring sheet and the lower support plate to delay the movement of the lower support plate, so that when the spring telescopic rod is compressed or expanded to the limit position, the lower support plate moves again, so that the upper support plate can stably support the mass concrete; S5. Switching spraying: When two adjacent upper support plates switch supports, one of the upper support plates presses down the lever to deflect the lower spray pipe, and uses the magnet on the side of the other upper support plate to attract the spray head to adjust the spraying direction of the lower spray pipe.

[0016] Compared with the prior art, the present invention has at least one of the following beneficial technical effects: The present invention cooperates two alternating plates and a frame-shaped lever in a group to make the upper support plate alternately support the large volume concrete, so that the water sprayed from the lower spray pipe can spray the part of the large volume concrete blocked by the upper support plate, thereby increasing the spraying area and making the spraying uniform.

[0017] Furthermore, the large volume of concrete is alternately supported by two adjacent upper support plates. When one of the upper support plates descends, the direction of the lever is changed, that is, the direction of the lower spray pipe is changed, so that the lower spray pipe is always directed toward the part of the large volume of concrete that is not supported by the upper support plates, thereby avoiding waste caused by spraying water on the upper support plates.

[0018] Furthermore, the toothless bevel gear and the whole bevel gear are used to cooperate to make the upper and lower spray pipes spray water intermittently, giving the water time to penetrate so that the water temperature can affect the position of the temperature sensor in the mass concrete, giving the temperature sensor time to react, thereby avoiding excessive spraying that leads to water waste and excessively low temperature of the mass concrete.

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0026] Example 1 This embodiment proposes a large volume concrete intelligent temperature control device, such as Figure 1 and Figure 6 As shown, it includes a spray bin 1, and a sub-bin 2 is fixedly installed on both sides of the spray bin 1. An upper spray pipe 3 is fixedly installed on the top inner wall of the spray bin 1, and a large volume of concrete with an internally installed temperature sensor is placed inside the spray bin 1. A lower spray assembly 5 is arranged on the bottom inner wall of the spray bin 1, and the lower spray assembly 5 includes a support frame and a lower spray pipe 56. The lower spray pipe 56 is arranged on the support frame, and the support frame is arranged inside the spray bin 1. The pipe mouth of the lower spray pipe 56 faces the bottom of the large volume of concrete, and the upper spray pipe 3 faces the top of the large volume of concrete. The large volume of concrete is sprayed by the upper spray pipe 3 and the lower spray pipe 56, and the spraying amount is controlled in conjunction with the temperature sensor inside the large volume of concrete.

[0027] like Figure 3 and Figure 4As shown, a support assembly 4 is provided inside the spray bin 1, and the support assembly 4 includes a transmission assembly, an alternating plate 45, a frame lever 47, a spring telescopic rod 48, a lower support plate 49 and an upper support plate 411. A plurality of alternating plates 45 are provided, two by two forming a group, and the alternating plates 45 slide at the connection between the spray bin 1 and the sub-bin 2. The transmission assembly includes a driving shaft 41, an elliptical disk 42, a track 43 and a sliding block 44. The end of the driving shaft 41 is rotatably connected to the sub-bin 2, and a plurality of elliptical disks 42 equidistantly distributed in a straight line are fixedly installed in the middle of the driving shaft 41. An elliptical track 43 is provided on the elliptical disk 42, and the sliding block 44 slides along the track 43. The end of the sliding block 44 is fixedly connected to one of the alternating plates 45 in a group, and the two alternating plates 45 are connected to each other through a frame lever 47.

[0028] like Figure 2 and Figure 5 As shown, a slide post 46 is installed on the top of the alternating plate 45, and the slide post 46 slides on the inner wall of the frame-shaped lever 47. The bottom of the frame-shaped lever 47 is rotatably connected to the spray chamber 1 through a rotating shaft, and the slide post 46 prevents the frame-shaped lever 47 from rotating and getting stuck. A guide block is fixedly installed on the bottom of the upper support plate 411, and the guide block slides up and down on the bottom inner wall of the spray chamber 1, which not only guides the upper support plate 411, but also limits the maximum moving distance of the lower support plate 49, and prevents the upper support plate 411 from rotating.

[0029] A motor is fixedly installed at the end of the driving shaft 41, and the motor drives the driving shaft 41 and the elliptical disk 42 to rotate. The elliptical disk 42 uses the track 43 to make the sliding block 44 and the alternating plate 45 move back and forth periodically, and connects two alternating plates 45 in a group through a frame-shaped lever 47, so that the moving directions of the two alternating plates 45 are opposite. One alternating plate 45 moves toward the inside of the sub-bin 2, so that the lower support plate 49 moves and lowers the height of the upper support plate 411 supported by it, and the other alternating plate 45 moves into the spray bin 1, so that the lower support plate 49 moves and increases the height of the upper support plate 411 supported by it, and alternately raises the two adjacent upper support plates 411, that is, alternately supports large-volume concrete, to prevent the upper support plate 411 from supporting large-volume concrete for a long time and blocking its top spraying.

[0030] The end of the alternating plate 45 is fixedly installed with a spring telescopic rod 48, and the end of the spring telescopic rod 48 is fixedly installed with a lower support plate 49, and the lower support plate 49 slides inside the spray chamber 1, and the upper support plate 411 slides up and down inside the spray chamber 1. Large inclined surfaces are provided on the lower support plate 49 and the upper support plate 411, and the inclined surface of the lower support plate 49 contacts the inclined surface of the upper support plate 411, and the upper support plate 411 supports the large volume of concrete. The upper support plate 411 is lifted up by the inclined surface of the lower support plate 49, thereby raising the upper support plate 411.

[0031] like Figure 5As shown, a spring sheet 410 is fixedly installed on the inner wall of the bottom of the spray bin 1 and located on the moving path of the upper support plate 411. A recess is provided at the connection between the spring sheet 410 and the spray bin 1. A snap-fit ​​is provided at the bottom of the lower support plate 49, and the spring sheet 410 is snap-fitted to the snap-fit. The spring telescopic rod 48, the spring sheet 410 and the bayonet cooperate. When the spring telescopic rod 48 is unfolded to the extreme position, the pulling force of the spring telescopic rod 48 breaks through the resistance of the spring sheet 410 to the lower support plate 49, so that the lower support plate 49 can be moved. At the same time, the elastic force of the spring telescopic rod 48 quickly pulls the lower support plate 49 to avoid the resistance between the large volume concrete and the lower support plate 49, which makes the lower support plate 49 unable to move; when the spring telescopic rod 48 is retracted to the extreme position, the thrust of the spring telescopic rod 48 breaks through the resistance of the spring sheet 410 to the lower support plate 49, so that the lower support plate 49 can be moved. At the same time, the elastic force of the spring telescopic rod 48 quickly pushes the lower support plate 49 to avoid the resistance between the large volume concrete and the lower support plate 49, which makes the lower support plate 49 unable to move.

[0032] In this embodiment, the upper support plate 411 alternately supports the large volume concrete through the cooperation of two alternating plates 45 and the frame lever 47 in a group, so that the water sprayed from the lower spray pipe 56 can be sprayed to the part of the large volume concrete blocked by the upper support plate 411, thereby increasing the spraying area and making the spraying uniform.

[0033] Example 2 Based on Example 1, this example proposes a large volume concrete intelligent temperature control device, such as Figure 2 and 6 As shown, the support frame includes a metal support tube 51, a turntable 52 and a lever 53. The bottom of the metal support tube 51 is fixedly connected to the spray chamber 1. The metal support tube 51 is connected to the lower spray pipe 56 through a hose. The turntable 52 is fixedly installed on the hose. The lever 53 is fixedly installed on the arc surface of the turntable 52. The lever 53 and the lower spray pipe 56 are located on the same straight line, and the lever 53 and the metal support tube 51 are staggered with each other.

[0034] The mass concrete is alternately supported by two adjacent upper support plates 411. When one of the upper support plates 411 descends, the upper support plate 411 presses down the lever 53, and the lever 53 is used to rotate the turntable 52 to change the direction of the lower spray pipe 56, so that the lower spray pipe 56 is directed toward the portion of the mass concrete that is not supported by the upper support plate 411.

[0035] A spray head 54 is fixedly installed at the end of the lower spray pipe 56. A plurality of lower spray assemblies 5 are provided and are equidistantly distributed in a straight line along the upper support plate 411. The lower spray assemblies 5 are distributed between two adjacent upper support plates 411. A magnet 55 is fixedly installed on the side of the upper support plate 411. Since the upper support plate 411 cannot completely squeeze the lower spray pipe 56 to the other side, the spray head 54 is attracted by the magnet 55, so that the lower spray pipe 56 is always directed toward the part of the mass concrete that is not supported by the upper support plate 411.

[0036] In this embodiment, the large volume concrete is alternately supported by two adjacent upper support plates 411. When one of the upper support plates 411 descends, the direction of the lever 53 is changed, that is, the direction of the lower spray pipe 56 is changed, so that the lower spray pipe 56 is always directed toward the part of the large volume concrete that is not supported by the upper support plate 411, thereby avoiding waste caused by spraying water on the upper support plate 411.

[0037] Example 3 Based on the above-mentioned embodiment 1 or embodiment 2, this embodiment proposes a large volume concrete intelligent temperature control device, such as Figure 7 As shown, a water delivery assembly 6 is provided inside the sub-bin 2, and the water delivery assembly 6 includes a delivery pipe 61, a turntable 52, a full bevel gear 63 and a spiral blade 65. The inner wall of the delivery pipe 61 is rotatably connected to the full bevel gear 63, and the end of the driving shaft 41 is fixedly installed with a toothless bevel gear 62 extending into the interior of the delivery pipe 61. The toothless bevel gear 62 and the full bevel gear 63 are meshed with each other, and the spiral blade 65 is fixedly installed on the top of the full bevel gear 63.

[0038] A partition 64 is fixedly installed inside the delivery pipe 61, and the whole bevel gear 63 is rotatably connected to the partition 64. A docking pipe 66 is fixedly installed on the arc surface of the delivery pipe 61 and near the top. The docking pipe 66 is connected to the upper spray pipe 3 and the lower spray pipe 56. The toothless bevel gear 62 is driven to rotate by the driving shaft 41, so that the whole bevel gear 63 rotates to deliver spray water. The diameter of the toothless bevel gear 62 is larger than that of the whole bevel gear 63, and the gear ratio is used to increase the rotation speed of the whole bevel gear 63.

[0039] The toothless bevel gear 62 cooperates with the full bevel gear 63, so that after the full bevel gear 63 rotates a certain number of times, the toothless bevel gear 62 idles, so that the spraying is suspended, giving the water time to penetrate, so that the water temperature can affect the position of the temperature sensor in the large volume of concrete, giving the temperature sensor time to react.

[0040] A method for intelligent temperature control of mass concrete is applied to the above-mentioned intelligent temperature control device for mass concrete, and the steps are as follows: S1, spray cooling: The motor drives the toothless bevel gear 62 and the full bevel gear 63 to rotate to transport water, and sprays water on the mass concrete through the upper spray pipe 3 and the lower spray pipe 56, and cooperates with the temperature sensor inside the mass concrete to control the spraying amount so that the temperature of the mass concrete reaches the set value; S2, adaptive buffering: since the temperature sensor is located inside the mass concrete, it takes a certain amount of time for the sprayed water to penetrate into the mass concrete. The toothless bevel gear 62 and the full bevel gear 63 are periodically meshed to give the water time to penetrate, so that the water temperature can affect the position of the temperature sensor inside the mass concrete. S3, avoid spraying: the motor drives the driving shaft 41 and the elliptical plate 42 to rotate, so that the alternating plate 45 reciprocates, and the alternating plate 45 cooperates with the frame lever 47 to move, so that two alternating plates 45 in a group move in opposite directions, so as to replace the upper support plate 411 located at the bottom of the mass concrete, so as to avoid the upper support plate 411 continuously covering the bottom of the mass concrete; S4, positioning support: the lower support plate 49 is positioned by the spring sheet 410, and the movement of the lower support plate 49 is delayed by the bayonet fit between the spring sheet 410 and the lower support plate 49, so that when the spring telescopic rod 48 is compressed or expanded to the limit position, the lower support plate 49 moves again, so that the upper support plate 411 stably supports the mass concrete; S5. Switching spraying: When two adjacent upper support plates 411 switch supports, one of the upper support plates 411 presses down the lever 53 to deflect the lower spray pipe 56, and uses the magnet 55 on the side of the other upper support plate 411 to attract the spray head 54 to adjust the spraying direction of the lower spray pipe 56.

[0041] In this embodiment, the toothless bevel gear 62 and the full bevel gear 63 cooperate to make the upper spray pipe 3 and the lower spray pipe 56 spray water intermittently, giving the water time to penetrate so that the water temperature can affect the position of the temperature sensor in the mass concrete, giving the temperature sensor time to react, and avoiding excessive water waste caused by spraying and excessively low temperature of the mass concrete.

[0042] The above specific embodiments are only several optional embodiments of the present invention. Based on the technical solutions of the present invention and the relevant inspirations of the above embodiments, those skilled in the art can make various alternative improvements and combinations to the above specific embodiments.

10. A method for intelligent temperature control of mass concrete, applied to the intelligent temperature control device for mass concrete as claimed in claims 1 to 9, characterized in that: The method steps are as follows: S1, spray cooling: the motor drives the toothless bevel gear (62) and the integral bevel gear (63) to rotate to transport water, and sprays water on the mass concrete through the upper spray pipe (3) and the lower spray pipe (56), and cooperates with the temperature sensor inside the mass concrete to control the spraying amount so that the temperature of the mass concrete reaches the set value; S2, adaptive buffering: since the temperature sensor is located inside the mass concrete, it takes a certain amount of time for the sprayed water to penetrate into the mass concrete. By periodically meshing the toothless bevel gear (62) and the full bevel gear (63), the water is given time to penetrate, so that the water temperature can affect the position of the temperature sensor inside the mass concrete. S3, avoiding spraying: the motor drives the driving shaft (41) and the elliptical plate (42) to rotate, so that the alternating plate (45) reciprocates, and the alternating plate (45) cooperates with the frame-shaped lever (47) to move, so that two alternating plates (45) in a group move in opposite directions, so as to replace the upper support plate (411) located at the bottom of the mass concrete, so as to prevent the upper support plate (411) from continuously covering the bottom of the mass concrete; S4, positioning support: positioning the lower support plate (49) by means of the spring sheet (410), and utilizing the bayonet fit between the spring sheet (410) and the lower support plate (49) to delay the movement of the lower support plate (49), so that when the spring telescopic rod (48) is compressed or expanded to the limit position, the lower support plate (49) moves again, so that the upper support plate (411) stably supports the mass concrete; S5, switching spraying: when the two adjacent upper support plates (411) switch supports, one of the upper support plates (411) presses down the lever (53) to deflect the lower spray pipe (56), and uses the magnet (55) on the side of the other upper support plate (411) to attract the spray head (54) to adjust the spraying direction of the lower spray pipe (56).
