Description

Technical Field

[0001] The present invention relates to the technical field of temperature control, and particularly relates to a method and device for intelligent temperature control of mass concrete. Background Art

[0002] Spray temperature control of mass concrete precast parts is an effective temperature control method, which can prevent quality problems such as cracks in precast parts due to too high or too low temperature. By spraying water on the surface of precast parts, the evaporation heat absorption of water is used to reduce the surface temperature of precast parts. At the same time, the penetration of water can make the internal temperature of precast parts uniform, so as to achieve the purpose of controlling the temperature of precast parts.

[0003] The spray temperature control of mass concrete includes a water supply system, a spray device and a control system. Through the temperature sensors in the mass concrete precast parts, the temperature inside the concrete is sensed, and the temperature change of the precast parts is monitored in real time. The controller controls the start and stop of the water pump and the spraying intensity of the nozzles according to the signals of the temperature sensors, realizing automatic spray temperature control. In order to make the bottom of the mass concrete also be sprayed, it is lifted by multiple support frames.

[0004] However, the support frames will block the bottom of the mass concrete, resulting in some positions at the bottom of the concrete not being sprayed, which not only affects the sprayed area of the concrete, but also causes uneven spray temperature control of the concrete, affecting the temperature control of the concrete. Summary of the Invention

[0005] The purpose of the present invention is to propose a method and device for intelligent temperature control of mass concrete aiming at the problem that some positions at the bottom of the concrete are blocked and cannot be sprayed in the background art.

A bayonet is provided at the bottom of the lower support plate, and the spring piece is snap-connected with the bayonet.

[0011] Optionally, a sliding column is installed on the top of the alternating plate. The sliding column slides inside the inner wall of the frame-shaped lever. The bottom of the frame-shaped lever is rotatably connected to the spray bin through a rotating shaft. A guiding square block is fixedly installed at the bottom of the upper support plate, and the guiding square block slides up and down on the inner wall of the bottom of the spray bin.

[0012] Optionally, the transmission component includes a driving shaft, an elliptical disc, a track and a sliding block. The end of the driving shaft is rotatably connected to the separation bin. A plurality of elliptical discs are fixedly installed in the middle of the driving shaft at equal intervals in a straight line. An elliptical track is provided on the elliptical disc, and the sliding block slides along the track. The end of the sliding block is fixedly connected to the alternating plate.

[0013] Optionally, the support frame includes a metal support pipe, a turntable and a lever. The bottom of the metal support pipe is fixedly connected to the spray bin. The metal support pipe is interconnected with the lower spray pipe through a hose. A turntable is fixedly installed at the hose. A lever is fixedly installed on the arc surface of the turntable. The lever and the lower spray pipe are on the same straight line, and the lever and the metal support pipe are misaligned with each other.

[0014] Optionally, a spray head is fixedly installed at the end of the lower spray pipe. A plurality of lower spray components are provided and are equally spaced in a straight line along the upper support plate. The lower spray components are distributed between two adjacent upper support plates, and a magnet is fixedly installed on the side of the upper support plate.

[0015] Optionally, a water delivery component is arranged inside the separation bin. The water delivery component includes a delivery pipe, a missing-tooth bevel gear, a complete bevel gear and a spiral blade. The complete bevel gear is rotatably connected to the inner wall of the delivery pipe. The missing-tooth bevel gear fixedly installed at the end of the driving shaft extends into the delivery pipe, and the missing-tooth bevel gear meshes with the complete bevel gear. A spiral blade is fixedly installed on the top of the complete bevel gear.

[0016] Optionally, the diameter of the missing-tooth bevel gear is larger than that of the complete bevel gear. A butt joint pipe is fixedly installed on the arc surface of the delivery pipe and near the top position. The butt joint pipe is communicated with the upper spray pipe and the lower spray pipe.

[0017] Optionally, a motor is fixedly installed at the end of the drive shaft, a water inlet pipe with a one-way valve is fixedly installed at the arc surface of the conveying pipe, a partition is fixedly installed inside the conveying pipe, and the integral bevel gear is rotatably connected to the partition.

[0018] A large-volume concrete intelligent temperature control method is applied to the above-mentioned large-volume concrete intelligent temperature control device, and its steps are as follows:

[0019] S1. Spraying and cooling: The motor drives the toothless bevel gear and the integral bevel gear to rotate to convey water, and the large-volume concrete is sprayed through the upper spray pipe and the lower spray pipe. In cooperation with the temperature sensor inside the large-volume concrete, the spraying amount is controlled to make the temperature of the large-volume concrete reach the set value.

[0020] S2. Adaptation and buffering: Since the temperature sensor is located inside the large-volume concrete, it takes a certain time for the sprayed water to soak into the large-volume concrete. Through the periodic meshing of the toothless bevel gear and the integral bevel gear, the soaking time of the water is given, so that the temperature of the water can affect the position of the temperature sensor inside the large-volume concrete.

[0021] S3. Avoiding spraying: The motor drives the drive shaft and the elliptical disc to rotate, so that the alternating plate reciprocates. The alternating plate cooperates with the frame-shaped lever to move, so that the two alternating plates in a group move in opposite directions to replace the upper support plate at the bottom of the large-volume concrete, avoiding the upper support plate continuously blocking the bottom of the large-volume concrete.

[0022] S4. Positioning and supporting: The lower support plate is positioned by the spring piece. Using the cooperation between the spring piece and the bayonet of the lower support plate, the movement of the lower support plate is delayed. When the spring telescopic rod is compressed or extended to the limit position, the lower support plate moves again, so that the upper support plate stably supports the large-volume concrete.

[0023] S5. Switching spraying: When switching the support between two adjacent upper support plates, one of the upper support plates presses down the lever to deflect the lower spray pipe, and the magnet on the side of the other upper support plate attracts the spray head to adjust the spraying direction of the lower spray pipe.

[0024] Compared with the prior art, the present application includes at least one of the following beneficial technical effects:

[0025] In the present invention, the two alternating plates in a group cooperate with the frame-shaped lever to alternately support the large-volume concrete, so that the water sprayed from the lower spray pipe can spray on the part of the large-volume concrete blocked by the upper support plate, increasing the spraying area and making the spraying uniform.

[0026] Furthermore, the large-volume concrete is supported alternately by two adjacent upper support plates. When one upper support plate descends, the orientation of the lever is changed, that is, the orientation of the lower spray pipe is changed, so that the lower spray pipe always faces the part of the large-volume concrete not supported by the upper support plate, avoiding waste caused by spraying water on the upper support plate.

[0027] Even further, the upper spray pipe and the lower spray pipe are made to spray water intermittently through the cooperation of the toothless bevel gear and the integral bevel gear, giving time for the water to soak in, enabling the temperature of the water to affect the position of the temperature sensor in the large-volume concrete, giving the temperature sensor reaction time, and avoiding waste of water caused by excessive spraying and too low temperature of the large-volume concrete.

[0041] Embodiment 1

[0042] This embodiment provides a large-volume concrete intelligent temperature control device, as Figure 1 and Figure 6As shown in the figure, it includes a spray bin 1. Separate bins ② are fixedly installed on both the left and right sides of the spray bin 1. An upper spray pipe 3 is fixedly installed on the inner wall of the top of the spray bin 1. Mass concrete with a temperature sensor installed inside is placed inside the spray bin 1. A lower spray assembly 5 is arranged on the inner wall of the bottom of the spray bin 1. 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 nozzle of the lower spray pipe 56 faces the bottom of the mass concrete, and the upper spray pipe 3 faces the top of the mass concrete. The mass concrete is sprayed through the upper spray pipe 3 and the lower spray pipe 56, and the spray volume is controlled in cooperation with the temperature sensor inside the mass concrete.

[0043] As Figure 3 and Figure 4 shown in the figure, a support assembly 4 is arranged inside the spray bin 1. The support assembly 4 includes a transmission assembly, an alternating plate 45, a frame-shaped 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 arranged, two in a group. The alternating plates 45 slide at the connection of the spray bin 1 and the separate bin 2. The transmission assembly includes a drive shaft 41, an elliptical disk 42, an orbit 43, and a sliding block 44. The end of the drive shaft 41 is rotatably connected to the separate bin 2. A plurality of elliptical disks 42 are fixedly installed in the middle of the drive shaft 41 at equal intervals in a straight line. An elliptical orbit 43 is opened on the elliptical disk 42. The sliding block 44 slides along the orbit 43. The end of the sliding block 44 is fixedly connected to one of the alternating plates 45 in a group. The two alternating plates 45 are connected to each other through a frame-shaped lever 47.

[0044] As Figure 2 and Figure 5 shown in the figure, a sliding column 46 is installed on the top of the alternating plate 45. The sliding column 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 bin 1 through a rotating shaft. The sliding column 46 prevents the frame-shaped lever 47 from being stuck in rotation. A guiding square block is fixedly installed at the bottom of the upper support plate 411. The guiding square block slides up and down on the inner wall of the bottom of the spray bin 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.

[0045] A motor is fixedly installed at the end of the drive shaft 41. The drive shaft 41 and the elliptical disc 42 are driven to rotate by the motor. The elliptical disc 42 uses the track 43 to make the slider 44 and the alternating plate 45 move periodically back and forth. A frame-shaped lever 47 is used to connect two alternating plates 45 in a group, so that the moving directions of the two alternating plates 45 are opposite. One alternating plate 45 moves into the internal part of the separation bin 2, so that the lower support plate 49 moves and reduces the height of the upper support plate 411 it supports. 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 it supports. The adjacent two upper support plates 411 are alternately raised, that is, the mass concrete is alternately supported, avoiding the upper support plate 411 supporting the mass concrete for a long time and blocking the top spray of the mass concrete.

[0046] A spring telescopic rod 48 is fixedly installed at the end of the alternating plate 45. The end of the spring telescopic rod 48 is fixedly installed with a lower support plate 49. The lower support plate 49 slides inside the spray bin 1. The upper support plate 411 slides up and down inside the spray bin 1. Large inclined surfaces are provided on both the lower support plate 49 and the upper support plate 411. The inclined surface of the lower support plate 49 contacts the inclined surface of the upper support plate 411. The upper support plate 411 supports the mass concrete. The lower support plate 49 is used to jack up the upper support plate 411 by the inclined surface, so as to raise the upper support plate 411.

[0047] As Figure 5 shown, a spring piece 410 is fixedly installed on the inner wall of the bottom of the spray bin 1 and on the moving path of the upper support plate 411. A notch is provided at the connection between the spring piece 410 and the spray bin 1. A bayonet is provided at the bottom of the lower support plate 49. The spring piece 410 is clamped with the bayonet. The spring telescopic rod 48, the spring piece 410 and the bayonet cooperate. When the spring telescopic rod 48 expands to the limit position and the pulling force of the spring telescopic rod 48 breaks through the resistance of the spring piece 410 to the lower support plate 49, 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 mass concrete and the lower support plate 49, resulting in the lower support plate 49 being unable to move. When the spring telescopic rod 48 contracts to the limit position and the pushing force of the spring telescopic rod 48 breaks through the resistance of the spring piece 410 to the lower support plate 49, 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 mass concrete and the lower support plate 49, resulting in the lower support plate 49 being unable to move.

[0048] In this embodiment, the upper support plate 411 alternately supports the mass concrete through the cooperation of two alternating plates 45 and a frame-shaped lever 47 in a group, so that the water sprayed from the lower spray pipe 56 can spray on the part of the mass concrete blocked by the upper support plate 411, increasing the spray area and making the spray uniform.

[0049] Embodiment 2

[0050] Based on Embodiment 1, this embodiment proposes an intelligent temperature control device for mass concrete, as Figure 2 and 6 shown. The support frame includes a metal support pipe 51, a turntable 52 and a lever 53. The bottom of the metal support pipe 51 is fixedly connected to the spraying bin 1. The metal support pipe 51 is interconnected with the lower spraying pipe 56 through a hose. The turntable 52 is fixedly installed at the hose. The lever 53 is fixedly installed at the arc surface of the turntable 52. The lever 53 and the lower spraying pipe 56 are on the same straight line, and the lever 53 is offset from the metal support pipe 51.

[0051] 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 so as to change the orientation of the lower spraying pipe 56, making the lower spraying pipe 56 face the part of the mass concrete not supported by the upper support plate 411.

[0052] A spraying head 54 is fixedly installed at the end of the lower spraying pipe 56. A plurality of lower spraying assemblies 5 are provided and are linearly and equidistantly distributed along the upper support plate 411. The lower spraying assemblies 5 are distributed between two adjacent upper support plates 411. A magnet 55 is fixedly installed at the side of the upper support plate 411. Since the upper support plate 411 cannot completely squeeze the lower spraying pipe 56 to the other side, the magnet 55 attracts the spraying head 54, so that the lower spraying pipe 56 always faces the part of the mass concrete not supported by the upper support plate 411.

[0053] In this embodiment, the mass concrete is alternately supported by two adjacent upper support plates 411. When one of the upper support plates 411 descends, the orientation of the lever 53 is changed, that is, the orientation of the lower spraying pipe 56 is changed, so that the lower spraying pipe 56 always faces the part of the mass concrete not supported by the upper support plate 411, avoiding waste caused by spraying water on the upper support plate 411.

[0054] Embodiment 3

[0055] Based on the above Embodiment 1 or 2, this embodiment proposes an intelligent temperature control device for mass concrete, as Figure 7 shown. A water delivery component 6 is arranged inside the separate bin 2. The water delivery component 6 includes a delivery pipe 61, a toothless bevel gear 62, a complete bevel gear 63 and a spiral blade 65. The inner wall of the delivery pipe 61 is rotatably connected to the complete bevel gear 63. The end of the drive shaft 41 is fixedly installed with a toothless bevel gear 62 extending into the inside of the delivery pipe 61. The toothless bevel gear 62 meshes with the complete bevel gear 63. The spiral blade 65 is fixedly installed at the top of the complete bevel gear 63.

[0056] A partition plate 64 is fixedly installed inside the conveying pipe 61. The integral bevel gear 63 is rotatably connected to the partition plate 64. A butt joint pipe 66 is fixedly installed at the arc surface of the conveying pipe 61 and near the top position. The butt joint pipe 66 is communicated with the upper spray pipe 3 and the lower spray pipe 56. The driving shaft 41 drives the toothless bevel gear 62 to rotate, so as to drive the integral bevel gear 63 to rotate to convey spray water. The diameter of the toothless bevel gear 62 is larger than that of the integral bevel gear 63, and the rotation speed of the integral bevel gear 63 is increased by using the gear ratio.

[0057] The toothless bevel gear 62 cooperates with the integral bevel gear 63. After the integral bevel gear 63 rotates a certain number of turns, the toothless bevel gear 62 idles, so that the spraying is paused, giving time for water immersion, enabling the temperature of the water to affect the position of the temperature sensor in the mass concrete, and giving the temperature sensor reaction time.

[0058] In this embodiment, the upper spray pipe 3 and the lower spray pipe 56 intermittently spray water through the cooperation of the toothless bevel gear 62 and the integral bevel gear 63, giving time for water immersion, enabling the temperature of the water to affect the position of the temperature sensor in the mass concrete, giving the temperature sensor reaction time, and avoiding waste of water caused by excessive spraying and too low temperature of the mass concrete.

[0059] A method for intelligent temperature control of mass concrete applies the above-mentioned intelligent temperature control device for mass concrete, and the steps are as follows:

[0060] S1. Spray cooling: The motor drives the toothless bevel gear 62 and the integral bevel gear 63 to rotate to convey water, and the upper spray pipe 3 and the lower spray pipe 56 spray water to spray the mass concrete, and cooperate 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;

[0061] S2. Adaptation buffer: Since the temperature sensor is located inside the mass concrete, it takes a certain time for the sprayed water to immerse into the mass concrete. Through the periodic meshing of the toothless bevel gear 62 and the integral bevel gear 63, time for water immersion is given, so that the temperature of the water can affect the position of the temperature sensor in the mass concrete;

[0062] S3. Avoidance spraying: The motor drives the drive shaft 41 and the elliptical disc 42 to rotate, so as to make the alternating plate 45 reciprocate. The alternating plate 45 cooperates with the frame-shaped lever 47 to move, so that the two alternating plates 45 in a group move in opposite directions to replace the upper support plate 411 at the bottom of the mass concrete, avoiding the upper support plate 411 continuously blocking the bottom of the mass concrete;

[0063] S4. Positioning and supporting: Position the lower support plate 49 through the spring piece 410. Utilize the bayonet fit between the spring piece 410 and the lower support plate 49 to delay the movement of the lower support plate 49. When the spring telescopic rod 48 is compressed or extended to the limit position, the lower support plate 49 then moves, enabling the upper support plate 411 to stably support the mass concrete.

[0064] S5. Spraying switching: When switching the support between two adjacent upper support plates 411, 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.

[0065] The above specific embodiments are merely several alternative embodiments of the present invention. Based on the technical solution of the present invention and the relevant revelations of the above embodiments, those skilled in the art can make various alternative improvements and combinations to the above specific embodiments.

A toothless bevel gear (62) fixedly installed at the end of the drive shaft (41) extends into the delivery pipe (61). The toothless bevel gear (62) meshes with the complete bevel gear (63). A spiral blade (65) is fixedly installed on the top of the complete bevel gear (63).

4. The intelligent temperature control device for mass concrete according to claim 3, characterized in that: The diameter of the toothless bevel gear (62) is larger than the diameter of the complete bevel gear (63). A butt joint pipe (66) is fixedly installed at the arc surface of the delivery pipe (61) and near the top position. The butt joint pipe (66) is communicated with the upper spray pipe (3) and the lower spray pipe (56).

5. The intelligent temperature control device for mass concrete according to claim 4, characterized in that: A motor is fixedly installed at the end of the drive shaft (41). A water inlet pipe with a check valve is fixedly installed at the arc surface of the delivery pipe (61). A partition plate (64) is fixedly installed inside the delivery pipe (61). The complete bevel gear (63) is rotatably connected to the partition plate (64).

6. A method for intelligent temperature control of mass concrete, which applies the intelligent temperature control device for mass concrete according to claim 5 above, and the steps are as follows: S1. Spray cooling: Drive the toothless bevel gear (62) and the complete bevel gear (63) to rotate by a motor to convey water, and spray water on the mass concrete through the upper spray pipe (3) and the lower spray pipe (56), and cooperate with the temperature sensor inside the mass concrete to control the spray volume so that the temperature of the mass concrete reaches the set value. S2. Adaptation and buffering: Since the temperature sensor is located inside the mass concrete, it takes a certain time for the sprayed water to penetrate into the mass concrete. Through the periodic meshing of the toothless bevel gear (62) and the complete bevel gear (63), the water penetration time is given so that the temperature of the water can affect the position of the temperature sensor inside the mass concrete. S3. Avoidance Spraying: The drive shaft (41) and the elliptical disc (42) are rotated by the motor to make the alternating plate (45) reciprocate. The alternating plate (45) cooperates with the frame-shaped lever (47) to move, so that the two alternating plates (45) in a group move in opposite directions to replace the upper support plate (411) at the bottom of the mass concrete, avoiding the upper support plate (411) continuously blocking the bottom of the mass concrete; S4. Positioning Support: The lower support plate (49) is positioned by the spring piece (410). By the bayonet fit between the spring piece (410) and the lower support plate (49), the movement of the lower support plate (49) is delayed. When the spring telescopic rod (48) is compressed or extended to the limit position, the lower support plate (49) moves again, making the upper support plate (411) stably support the mass concrete; S5. Switching Spraying: When switching the support between two adjacent upper support plates (411), one of the upper support plates (411) presses down the push rod (53) to deflect the lower spray pipe (56), and the magnet (55) on the side of the other upper support plate (411) attracts the spray head (54) to adjust the spraying direction of the lower spray pipe (56).
