Description

Technical Field

[0001] This utility model belongs to the field of concrete temperature control technology, and in particular relates to a large-volume concrete temperature control device that is easy to adjust according to the size of the concrete. Background Technology

[0002] Concrete curing involves artificially creating specific humidity and temperature conditions to allow freshly poured concrete to harden and strengthen normally or at an accelerated pace. The gradual hardening and strength gain of concrete is a result of cement hydration, which requires specific temperature and humidity conditions. If these conditions are not present in the surrounding environment, the temperature of the air will cause moisture loss from the concrete, leading to cracks. Therefore, artificial curing of concrete is necessary.

[0003] For example, Chinese patent CN222348898U discloses an automatic temperature control device for large-volume concrete. By moving the nozzle up and down, water is sprayed onto the surface of the concrete block to cool it down. This can improve the uniformity of cooling of the concrete block. Spraying water onto the surface of the concrete block can keep the surface moist, prevent the concrete block from drying out prematurely and cracking, and help maintain stable humidity inside the concrete block, thus ensuring the quality and strength of the concrete.

[0004] However, due to the difference in width of the concrete blocks, the distance between the spraying sides needs to be adjusted according to the width of the concrete blocks. Otherwise, the spraying effect will decrease or the spraying operation will not be possible for concrete blocks with large size differences. Utility Model Content

[0005] The purpose of this invention is to provide a temperature control device for large-volume concrete, which can adapt to concrete of different sizes by adjusting the spacing of the water spraying device.

[0006] The technical solution adopted by this utility model to solve the above problems is: a large-volume concrete temperature control device, including a water supply component, a water spraying component, a lifting component, and a placement component; the water spraying component includes:

[0007] Mounting plate, the interior of which has straight grooves;

[0008] A two-way lead screw is rotatably connected to the inner wall of a linear groove;

[0009] The adjusting motor is fixedly connected to one end of the double-acting lead screw;

[0010] Two sets of L-shaped blocks are provided, which are threadedly connected to the positive and negative threads of the bidirectional lead screw respectively.

[0011] The water spray assembly is mounted on the L-shaped block.

[0012] A further preferred technical solution is that the water spray assembly includes a water pipe with several nozzles on its surface, a rotating shaft fixedly connected to one end of the water pipe, a deflection gear fixedly sleeved on the rotating shaft, a lifting gear plate meshing with the deflection gear, a return frame fixedly connected to the lifting gear plate, a cam abutting against the inner side of the return frame, a rotating rod set on the cam, a fixed tube slidably sleeved on the rotating rod, and a driven gear set on the fixed tube.

[0013] A further preferred technical solution is that the lifting assembly includes a base plate, a vertical slot plate fixedly connected to the base plate, a threaded rod rotatably connected to the vertical slot plate, a drive motor fixedly connected to the threaded rod, a connecting block threadedly connected to the threaded rod, and a U-shaped plate disposed on the connecting block; the mounting plate is disposed on the inner side of the U-shaped plate.

[0014] A further preferred technical solution is that the lifting assembly also includes a fixed toothed plate, a lifting gear meshing with the fixed toothed plate, a long rod disposed on the lifting gear and passing through the U-shaped plate, and a driving gear fixedly sleeved on the long rod; the driven gear meshes with the driving gear.

[0015] A further preferred technical solution is that the placement component includes a placement slot plate disposed on the base plate.

[0016] A further preferred technical solution is that: the water conveying assembly includes a liquid storage tank installed on the base plate, a pump whose input end is connected to the liquid storage tank, a diversion pipe connected to the output end of the pump, and a connecting pipe connected to the diversion pipe; the water pipe is connected to the connecting pipe.

[0017] A further preferred technical solution is that a fixing rod is fixedly connected to the fixing tooth plate, and one end of the fixing rod is fixedly connected to the vertical groove plate.

[0018] A further preferred technical solution is that: a sliding disc is fixedly connected to the rotating rod, a locking block is fixedly connected to the sliding disc, and a slot for the locking block to move is provided on the inner wall of the fixed tube.

[0019] A further preferred technical solution is that a limiting plate is sleeved on the connecting pipe, and the bottom of the limiting plate is fixedly connected to the top of the mounting plate.

[0020] A further preferred technical solution is that the L-shaped block is provided with a lifting groove, and the lifting tooth plate is slidably disposed inside the lifting groove.

[0021] In summary, this utility model has the following advantages:

[0022] 1. According to the width of the concrete block, the present invention starts the adjusting motor to make the bidirectional screw rotate, thereby changing the distance between the two L-shaped blocks, and thus adjusting the distance between the two water pipes, so that the spraying position of the two water pipes can be adapted to the width of the concrete block.

[0023] 2. This utility model uses a drive motor to rotate the threaded rod, causing the connecting block to move up and down along with the U-shaped plate. This, in turn, causes the mounting plate to move up and down along with the water pipe in the vertical direction. During this process, the lifting gear is engaged by the fixed gear plate, causing the long rod to rotate. This, in turn, causes the driving gear to rotate with the driven gear, and the fixed tube to rotate along with the rotating rod. This causes the cam to continuously strike the return frame, causing the lifting gear to move up and down in the vertical direction. This causes the deflection gear to swing back and forth along with the water pipe via the rotating shaft. As the water pipe descends, it swings and sprays water, making the cooling effect of the device more comprehensive. Attached Figure Description

After reading this specification, those skilled in the art can make modifications to this embodiment without contributing any inventive step, but as long as they are within the scope of the claims of the present utility model, they are protected by patent law.

[0032] Example:

[0033] A large-volume concrete temperature control device includes a water supply component, a water spraying component, a lifting component, and a placement component; the water spraying component includes:

[0034] Mounting plate, the interior of which has straight grooves;

[0035] A two-way lead screw is rotatably connected to the inner wall of a linear groove;

[0036] The adjusting motor is fixedly connected to one end of the double-acting lead screw;

[0037] Two sets of L-shaped blocks are provided, which are threadedly connected to the positive and negative threads of the bidirectional lead screw respectively.

[0038] The water spray assembly is mounted on the L-shaped block.

[0039] The water supply component is responsible for delivering water to the water spraying component to ensure a continuous water supply for the water spraying operation. It typically includes components such as pipes and water pumps to provide a stable water flow to the water spraying component.

[0040] The water spray assembly uses nozzles to spray water onto the concrete surface to cool and moisturize it, preventing cracks caused by moisture loss. The lateral spacing of the two spray devices is adjusted using a two-way screw, an adjustable motor, and an L-shaped block to accommodate concrete blocks of different widths and ensure uniform water coverage.

[0041] The lifting component drives the water spraying component to move up and down, adjusting the spraying height to adapt to concrete blocks of different thicknesses or different operational needs, thereby improving the vertical range and uniformity of water spraying coverage.

[0042] The placement component is used to support and secure large concrete blocks to be cured, ensuring their stable position during water spraying and temperature control, and preventing displacement that could affect the spraying effect. It may include an adjustable support structure to accommodate concrete of different sizes.

[0043] In a preferred embodiment, such as Figures 1-5As shown, a large-volume concrete temperature control device includes a base plate 1. A placement trough plate 2 is fixedly connected to the top left side of the base plate 1. Support blocks are fixedly connected at equal intervals to the bottom of the inner wall of the placement trough plate 2.

[0044] It also includes a mounting plate 10, the right side of which is fixedly connected to the left side of the U-shaped plate 9. The mounting plate 10 has a straight groove inside, and a bidirectional screw 11 is rotatably connected to the inner wall of the straight groove. One end of the bidirectional screw 11 is fixedly connected to an adjusting motor. Two symmetrically arranged L-shaped blocks 12 are threadedly connected to the surface of the bidirectional screw 11. A rotating shaft 13 is rotatably connected to the inner wall of the L-shaped block 12. One end of the rotating shaft 13 is fixedly connected to a water pipe 14. The surface of the water pipe 14 is connected to one end of the connecting pipe 5. Spray nozzles are connected to the surface of the water pipe 14 at equal intervals. One end of the water pipe 14 is rotatably connected to an L-shaped fixing plate through a support rod. The surface of the mounting plate 10 has a square through-hole for the L-shaped fixing plate to move. One end of the L-shaped fixing plate is fixedly connected to the surface of the L-shaped block 12 for adjusting the spraying distance of the device.

[0045] It also includes a fixed tube 15, on the surface of which are two seated bearings. The surface of the seated bearings is fixedly connected to the right side of the mounting plate 10, ensuring the normal rotation of the fixed tube 15. Two rotating rods 16 are slidably connected inside the fixed tube 15. A sliding disc is fixedly connected to the other end of each rotating rod 16. Two locking blocks are fixedly connected to the surface of the sliding disc. A slot is provided on the inner wall of the fixed tube 15 for the locking blocks to move, ensuring that the rotating rods 16 and the fixed tube 15 rotate together. One end of the rotating rod 16 is rotatably connected to the inner wall of an L-shaped block 12. A cam 17 is fitted onto the surface of the L-shaped block 12. The surface of the cam 17 abuts against a return frame 18. A lifting gear plate 19 is fixedly connected to the top of the return frame 18. A lifting groove is provided on the inner wall of the L-shaped block 12. The surface of the lifting gear plate 19... The sliding arrangement inside the lifting groove ensures the normal operation of the lifting toothed plate 19. A deflection gear 20 is meshed with the surface of the lifting toothed plate 19. The deflection gear 20 is sleeved on the outside of the rotating shaft 13. A driven gear 21 is sleeved on the surface of the fixed tube 15. A driving gear 22 is meshed with the surface of the driven gear 21. A long rod 23 is connected through the shaft of the driving gear 22. A lifting gear 24 is meshed with the surface of the long rod 23. A fixed toothed plate 25 is meshed with the surface of the lifting gear 24. Two fixed rods are fixedly connected to the surface of the fixed toothed plate 25. One end of the fixed rod is fixedly connected to the surface of the vertical groove plate 6 to ensure the normal operation of the fixed toothed plate 25. The bottom of the fixed toothed plate 25 is fixedly connected to the top of the base plate 1 for swinging spraying with the water pipe 14.

[0046] The implementation principle of a large-volume concrete temperature control device in this embodiment is as follows: The drive motor is started, causing the threaded rod 7 to rotate, which in turn causes the connecting block 8 to move up and down along with the U-shaped plate 9. This, in turn, causes the mounting plate 10 to move up and down along with the water pipe 14 in the vertical direction. During this process, the lifting gear 24 is engaged by the fixed toothed plate 25, causing the long rod 23 to rotate. This, in turn, causes the driving gear 22 to rotate along with the driven gear 21, causing the fixed pipe 15 to rotate along with the rotating rod 16. This causes the cam 17 to continuously strike the return frame 18, causing the lifting toothed plate 19 to move up and down in the vertical direction. This causes the deflection gear 20 to swing back and forth along with the water pipe 14 via the rotating shaft 13. As the water pipe 14 descends, it swings and sprays water. When the water pipe 14 moves to the bottom, it can also spray water to cool the bottom of the concrete block, making the cooling effect of the device more comprehensive.

[0047] Before use, the adjusting motor is started according to the width of the concrete block, causing the bidirectional lead screw 11 to rotate. This changes the distance between the two L-shaped blocks 12, thereby adjusting the distance between the two water pipes 14. This allows the spraying position of the two water pipes 14 to be adapted to the width of the concrete block. At the same time, when the two L-shaped blocks 12 move, they will move the rotating rod 16 inside the fixed pipe 15, ensuring the normal rotation of the fixed pipe 15. By adjusting the spraying distance between the two water pipes 14, the device can be adapted to concrete blocks of different widths, thus improving the device's adaptability.
