Description

Technical Field

[0001] This invention relates to the field of concrete specimen curing technology, specifically a portable energy-saving curing box for concrete specimens. Background Technology

[0002] As the core carrier for evaluating the strength of concrete structures, concrete test blocks must strictly follow the requirements of the "Standard for Test Methods of Physical and Mechanical Properties of Concrete" (GB / T 50081-2019) during their curing process, maintaining a standard environment with a temperature of 20±2℃ and a relative humidity of ≥95%. Otherwise, the test block strength test results will be biased, affecting the evaluation of project quality.

[0003] Currently, when curing concrete test blocks, the blocks are statically placed on storage racks, with the bottom surface in contact with the racks obstructed, creating dead zones. The circulating airflow within the curing chamber is difficult to penetrate these gaps due to the rack's obstruction. The statically placed blocks exhibit significant strength differentiation due to temperature and humidity differences across their surfaces, affecting test results. Manually turning the blocks every 6-8 hours to change the contact surfaces causes frequent opening and turning, leading to fluctuations in temperature and humidity within the chamber, high energy consumption, and disruption of the overall curing environment, ultimately impacting the curing process. Summary of the Invention

[0004] This invention provides a portable energy-saving curing box for concrete test blocks, which can automatically flip the concrete test blocks inside the box, facilitating uniform curing of each side of the test block and avoiding the problem of uneven curing caused by static placement of the test blocks. Moreover, it can ensure a stable curing environment without opening the sealed door when flipping the test blocks. This solves the problems mentioned in the background art, such as the bottom surface of the test blocks being blocked when statically placed on the storage rack, forming dead corners, and the fluctuation of temperature and humidity inside the box caused by frequent opening and flipping.

The second, third, and fourth airbags are all arranged corresponding to the ventilation grooves. There is unidirectional communication between the first and second airbags, between the second and third airbags, between the third and fourth airbags, and between the fourth airbag and the first airbag, and a one-way throttling valve is installed between each pair of them.

[0011] As an optional solution for the portable concrete test block energy-saving curing box of the present invention, the air bladders are all made of silicone, and the air bladders are all strip-shaped, the ventilation grooves are long strips, and the air bladders and ventilation grooves are spaced apart.

[0012] As an optional solution for the portable energy-saving curing box for concrete test blocks described in this invention, the storage rack has an installation cavity on the side away from the sealed door, and an electric push rod is fixedly installed on the side of the box away from the sealed door, with a push rod fixedly connected to one end of the electric push rod.

[0014] As an optional embodiment of the portable energy-saving curing box for concrete test blocks described in this invention, the baffle is located in the center of one side of the storage rack, and the baffle is arranged parallel to the rotating plate.

[0015] The present invention has the following beneficial effects:

[0016] 1. This portable energy-saving curing box for concrete test blocks seals the test blocks within the box by placing them in a storage rack and closing the sealed door. A circulating airflow, ensuring constant temperature and humidity, is blown into the box through a channel to maintain the curing process. A motor drives a rotating shaft and storage rack, causing the test blocks to revolve around the shaft. The 360-degree rotation of the storage rack allows the test blocks to rotate on all four sides, ensuring even air contact and uniform curing. Ventilation grooves on the storage rack further confine the test blocks within the box. Simultaneously, the airflow can pass through the ventilation grooves and contact the surface of the test block, achieving uniform curing of the test block. When the storage rack revolves around the rotating axis to a lower position inside the box, the gear meshes with the arc-shaped rack. The gear drives the first airbag to rotate inside the storage rack, thereby driving the test block on the first airbag to rotate. Ultimately, the front, back, top, bottom, left, and right sides of the test block can all contact the airflow, improving the uniformity of curing of the test block. There is no need to manually open the curing box to manually flip the test block, avoiding frequent opening of the box and the resulting temperature and humidity fluctuations. This avoids the instantaneous energy loss and system energy replenishment loss caused by opening the door from the source. Furthermore, the stable operating state reduces equipment fatigue energy consumption, achieving energy-saving effects and ensuring the stability of temperature and humidity inside the curing box.

[0017] 2. In this portable energy-saving curing box for concrete test blocks, to prevent damage to the test blocks when they are turned over, a first, second, third, and fourth air chamber are used to cushion the blocks. When the test block falls onto the rotating plate, its weight compresses the first air chamber, and the gas inside the first air chamber enters the second air chamber through a one-way throttle valve, thus cushioning the test block and inflating the next air chamber. As the storage rack continues to rotate clockwise, the test block impacts the next air chamber, which in turn cushions the test block, creating a continuous cycle to prevent the test block from turning over inside the storage rack. To prevent damage to the test block caused by direct contact with the storage rack, and to further reduce wear during flipping, the storage rack is equipped with a first roller and a second roller. When the test block is flipped, it slides along the first and second rollers until it makes contact. The first and second rollers are designed to reduce wear on the test block. When the airbag cushions the test block, the air in the current airbag is squeezed into the next airbag, causing the current airbag to contract and slowly bring the test block into contact with the first or second roller, further reducing wear and improving the curing effect on the test block.

[0018] 3. This portable energy-saving concrete test block curing box is equipped with an electric push rod to facilitate the removal of cured test blocks from the storage rack. The push rod moves a pusher rod, which pushes the cured test block out of the storage rack. When the pusher rod extends, it contacts a rotating plate, causing the plate to rotate within the mounting cavity. The rotation of the plate pulls the connecting rope. A baffle and a torsion spring are included. After the test block is placed in the storage rack, the baffle returns to its original position under the action of the torsion spring, preventing the test block from falling out. When the connecting rope is pulled, the movement of the rope rotates the baffle, causing the torsion spring to be stressed. The baffle then releases its obstruction, allowing the pusher rod to continue pushing the test block out of the storage rack, facilitating the removal of the cured test block.

[0028] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0029] Example 1, please refer to Figures 1 to 8 A portable energy-saving curing box for concrete test blocks includes a base 1, a box body 2 mounted on top of the base 1, a sealed door 3 rotatably connected to the surface of the box body 2, a motor 8 located on the side of the box body 2 away from the sealed door 3, a rotating shaft 9 fixedly connected to the output shaft end of the motor 8, the rotating shaft 9 rotatably connected inside the box body 2, and the rotating shaft 9 coincides with the axis of the box body 2, multiple mounting rods 10 evenly distributed on the surface of the rotating shaft 9, a storage rack 11 fixedly connected to one end of the mounting rod 10, a ventilation groove 12 opened on the surface of the storage rack 11, a rotating disk 13 rotatably connected to the side of the storage rack 11 away from the mounting rods 10, a gear 14 rotatably connected to the side of the rotating disk 13 away from the mounting rods 10, and an arc-shaped rack 15 meshing with the gear 14 installed on the inner wall of the box body 2, the arc-shaped rack 15 being installed at a lower position inside the box body 2.

[0030] The base 1 has an internal cavity with a constant temperature and humidity device inside. The base 1 is connected to the box 2 through a through groove 33. The surface of the base 1 has a water level observation port 6. The side of the base 1 has a water inlet 7. The bottom of the base 1 has casters 5.

[0031] The box 2 is cylindrical in shape, and the inner wall of the box 2 is covered with a polyurethane insulation layer. The sealing door 3 is equipped with a magnetic sealing strip at the contact edge with the box 2.

[0032] When curing concrete test blocks, refer to Figure 1 - Figure 4 Open the sealed door 3, place the test block to be cured into the storage rack 11, close the sealed door 3, and the constant temperature and humidity device in the base 1 sends airflow into the chamber 2 to maintain a constant temperature and humidity inside the chamber 2. The test block comes into contact with the air inside the chamber 2 through the ventilation groove 12 on the storage rack 11, achieving the purpose of curing the test block. During the curing of the test block, the motor 8 runs for a period of time after a set interval, realizing the automatic flipping of the test block. The motor 8 drives the rotating shaft 9 to rotate, which in turn drives the storage rack 11 to rotate around the rotating shaft 9, achieving the purpose of flipping the test block inside the rotating shaft 9, so that the four sides of the test block are evenly in contact with the air inside the chamber 2, improving the uniformity of the curing of the test block.

[0033] To further improve the curing effect, ensure the uniformity of curing, and prevent the top and bottom surfaces of the test block from being constantly in contact with air, thus avoiding the uneven curing of the sides of the test block, a gear 14 and an arc-shaped rack 15 are installed. When the storage rack 11 moves the test block to its lowest point in the housing 2, one side of the test block will contact the rotating disk 13, and the other side will be in contact with the side wall of the storage rack 11. The storage rack 11 continues to rotate clockwise until it is tilted to the left and right. Under the action of gravity, the test block slides towards the center of the rotating disk 13. At this time, the gear 14 meshes with the arc-shaped rack 15, and the gear 14 drives the rotating disk 13 to rotate 90°, causing the test block to rotate. This rotation, in conjunction with the revolution of the storage rack 11, ensures that the front and back surfaces of the test block also flip, so that all six surfaces of the test block are in contact with the storage rack 11, thereby improving the curing effect of the test block. During the meshing process of gear 14 and arc-shaped rack 15, the rotating disk 13 rotates 90° twice, thus resetting the rotating disk 13. An observation window 4 is provided on the sealed door 3 to facilitate observation of the maintenance status inside the enclosure 2.

[0034] The constant temperature and humidity device consists of a compressor, condenser, evaporator, heating element, ultrasonic humidifier, water tank, circulating fan, temperature and humidity sensors, and control panel. The temperature and humidity are set on the control panel, and the microcomputer controller compares the real-time temperature and humidity with the set values. If the temperature is higher than 22°C, the compressor starts; if the temperature is lower than 18°C, the heating element starts. If the humidity is lower than 95%, the ultrasonic humidifier starts, spraying water mist into the chamber 2. The circulating fan operates continuously or intermittently, forcing airflow within the chamber 2 to ensure uniform temperature and humidity in all corners. This is existing technology and will not be described further.

[0035] Example 2 is an improvement upon Example 1. For details, please refer to [link / reference]. Figures 1 to 8 Each ventilation groove 12 is uniformly provided with multiple first rollers 20. The axis of each first roller 20 is parallel to the axis of the box body 2. The first roller 20 is a rubber column and the diameter of the first roller 20 is greater than the depth of the ventilation groove 12. Multiple second rollers 21 are uniformly distributed on the top of the rotating disk 13. The second rollers 21 are rotatably connected to the top of the rotating disk 13.

[0036] The top of the rotating disk 13 is uniformly provided with a plurality of first airbags 16. The first airbags 16 are spaced apart from the second rollers 21 and are perpendicular to the second rollers 21. The inflation thickness of the first airbags 16 is greater than the diameter of the second rollers 21.

[0037] Multiple second airbags 17 are provided on the inner wall of the storage rack 11 on the right side of the rotating disk 13, multiple third airbags 18 are provided on the inner wall of the storage rack 11 away from the rotating disk 13, and multiple fourth airbags 19 are provided on the inner wall of the storage rack 11 on the left side of the rotating disk 13. The second airbags 17, third airbags 18 and fourth airbags 19 are all arranged corresponding to the ventilation grooves 12. There is unidirectional communication between the first airbag 16 and the second airbag 17, between the second airbag 17 and the third airbag 18, between the third airbag 18 and the fourth airbag 19, and between the fourth airbag 19 and the first airbag 16, and a one-way throttle valve is installed between each pair.

[0038] All airbags are made of silicone and are strip-shaped. The ventilation groove 12 is long and narrow, and the airbags and ventilation groove 12 are spaced apart.

[0039] When flipping the test block, to avoid damaging it, refer to... Figure 5 and Figure 8 In the initial position, the airbag at the bottom of each storage rack 11 is inflated to facilitate the initial placement of the test block. The weight of the test block will squeeze the gas in the current airbag into the next airbag, preparing for the test block to flip and buffer. The storage rack 11 rotates clockwise around the rotating axis 9, and the airbags inflate the next airbag counterclockwise around the storage rack 11.

[0040] The rotating shaft 9 drives the storage rack 11 to rotate clockwise around the rotating shaft 9. Taking the storage rack 11 at its highest point as the initial point, the test block is at the bottom surface of the storage rack 11. At this time, the test block will compress the gas in the third air bladder 18 into the fourth air bladder 19. After the gas in the third air bladder 18 is squeezed out, the test block will come into contact with the first roller 20. When the storage rack 11 rotates, the test block will slide along the first roller 20 and come into contact with the right side of the storage rack 11. Then, as the storage rack 11 continues to rotate, the right side of the test block will come into contact with the bottom surface of the storage rack 11. At this time, the storage rack 11 rotates 90° to achieve one flip. The setting of the first roller 20 reduces the wear of the test block when flipping, improves the maintenance effect, and when flipping, the compression of the air bladder on the bottom surface of the storage rack 11 by the test block buffers the test block and inflates the right air bladder. This achieves the purpose of the air bladder on the next side always buffering the test block that is about to be flipped when the test block is flipped. The storage rack 11 rotates 90° from its initial point, inflating the third airbag 18 into the fourth airbag 19. It then rotates another 90°, inflating the fourth airbag 19 into the first airbag 16. The first airbag 16 then inflates the second airbag 17, and the third airbag 18 inflates the fourth airbag 19, in a continuous cycle. The inflation and deflation of the airbags require no additional power; they are self-driven by mechanical movement, reducing energy waste.

[0041] Example 3 is an improvement upon Example 1. For details, please refer to [link / reference]. Figures 1 to 8 The storage rack 11 has an installation cavity 24 on the side away from the sealing door 3. An electric push rod 22 is fixedly installed on the side of the box body 2 away from the sealing door 3. One end of the electric push rod 22 is fixedly connected to a push rod 23.

[0042] A rotating plate 25 is symmetrically rotatably connected inside the mounting cavity 24. A first mounting groove 26 is provided on the rotating plate 25. A connecting rope 27 is fixedly connected inside the first mounting groove 26. A fixed seat 28 is symmetrically arranged on the side of the storage rack 11 near the sealing door 3. A baffle 29 is rotatably connected inside the fixed seat 28. A second mounting groove 30 is provided inside the baffle 29. The other end of the connecting rope 27 is fixedly connected to the second mounting groove 30. A fixed block 31 is fixedly connected to one side of the storage rack 11. A torsion spring 32 is provided on the top of the fixed block 31. One end of the torsion spring 32 is fixedly connected to the rotating shaft of the baffle 29.

[0043] The baffle 29 is located in the center of one side of the storage rack 11, and the baffle 29 is arranged parallel to the rotating plate 25.

[0044] To facilitate the removal of the cured test blocks from storage rack 11, please refer to... Figure 5 - Figure 8When the storage rack 11 rotates the test block to the electric push rod 22, the electric push rod 22 is activated, causing the push rod 23 to extend. When the push rod 23 extends, it contacts the rotating plate 25, thereby driving the rotating plate 25 to rotate within the mounting cavity 24. The rotation of the rotating plate 25 pulls the connecting rope 27 to move, thereby driving the baffle 29 to rotate, thus releasing the baffle 29 from obstructing the test block. As the push rod 23 continues to extend and contact the test block, it pushes the test block out of the storage rack 11, making it easier to retrieve the test block.

[0045] To prevent the second roller 21 from causing wear on the bottom of the test block when it is pushed out, the storage rack 11 rotates between 180° and 270° from its initial point. The rotating disk 13 meshes with the arc-shaped rack 15, and the rotation of the rotating disk 13 drives the test block to rotate. As the rotating disk 13 rotates, it also drives the second roller 21 to rotate. When the axis of the second roller 21 is perpendicular to the axis of the housing 2, the electric push rod 22 is activated, pushing the test block out of the storage rack 11. At this time, the second roller 21 makes rolling contact with the bottom of the test block, avoiding wear on the bottom of the test block and facilitating the removal of the test block from the storage rack 11. After the test block is pushed out, the arc-shaped rack 15 continues to mesh with the rotating disk 13 until the rotating disk 13 rotates again, making the axis of the second roller 21 parallel to the axis of the housing 2, thus completing the reset.

[0047] The above are merely preferred embodiments of the present invention. It should be noted that those skilled in the art can make various improvements and modifications without departing from the technical principles of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
