Description

Technical Field

[0001] The utility model relates to the technical field of concrete, in particular to an accelerated curing box. Background Art

[0002] Concrete is a construction material made of cement, sand, gravel and other materials mixed with water. After pouring, the concrete can gradually solidify and harden mainly because of the hydration of cement, and the hydration requires appropriate temperature and humidity conditions. Therefore, in order to ensure that the concrete has suitable hardening conditions and its strength continues to increase, the concrete must be cured.

[0003] After searching, it is found that a concrete accelerated curing box is disclosed in a Chinese patent document [Application No.: CN202321107034.1]. This concrete accelerated curing box includes a box body, a box door is movably installed at the front end of the box body through a hinge, an observation window is arranged in the middle of the front end of the box door, support feet are fixedly installed at the four corners of the lower end of the box body, a controller is fixedly installed at the right end of the box body, two slide grooves are opened on the left and right inner walls of the box body, and the two slide grooves on the same side are arranged front and back, a plurality of partitions are slidably installed in the four slide grooves, and a plurality of positioning holes are opened on the left and right inner walls of the box body.

[0004] The curing box disclosed in the patent can adjust the position of the partition according to the size of the concrete test block when in use. However, when in use, the staff is required to carry the concrete test blocks to the surface of the partition in sequence, and the space between the partitions is small, which makes it inconvenient for the staff to place the concrete test blocks. The friction between the concrete test blocks and the partitions is large when directly pushing them, which makes it inconvenient for the staff to place the concrete test blocks.

[0005] At the same time, the density of concrete test blocks is relatively large, and the concrete test blocks are also relatively heavy. When placing the concrete test blocks, the workers are required to carry them one by one, which consumes a lot of physical energy for the workers. In addition, the safety is poor during the transportation process, and the concrete test blocks are prone to falling. This not only increases the workload of the workers, but also reduces the safety of the workers when placing the concrete test blocks. Utility Model Content

[0023] See also Figure 1-4As shown, an accelerated curing box includes a placement box 1, which is used to place concrete test blocks that need to be cured. A curing mechanism 2 is installed on one side of the placement box 1, and the curing mechanism 2 can control the temperature and humidity inside the placement box 1, so as to accelerate the curing speed of the concrete test blocks. A placement shell 3 is arranged inside the placement box 1, and the placement shell 3 is used to place the concrete test blocks that need to be cured. Both sides of the bottom of the placement shell 3 are installed with mounting mechanisms 4, and the mounting mechanisms 4 can adjust the position of the placement shell 3, so that the curing box can cure concrete test blocks of different sizes, thereby improving the applicability of the curing box. Ventilation slots 5 are opened on the surface of the placement shell 3, and the air inside the placement box 1 can be more circulated under the action of the ventilation slots 5. , a ball 6 is installed on the surface of the placement shell 3, and the number of the ball 6 is several. Under the action of the ball 6, when the staff places the concrete test block on the surface of the placement shell 3, the concrete test block can be directly pushed to move, which is more convenient. It not only reduces the workload of the staff, but also improves the efficiency of placing the concrete test block. The inner cavity of the placement shell 3 is installed with a protective mechanism 7. Under the action of the protective mechanism 7, the edge of the placement shell 3 can be blocked, so that the concrete test block will not fall easily on the surface of the placement shell 3. A stepper motor 8 is bolted to the top of the placement box 1. Belt pulleys 9 are arranged on both sides of the top of the placement box 1. The bottom of the belt pulley 9 penetrates into the interior of the placement box 1 and is rotatably connected to the inner wall of the penetration. A threaded rod 10 is fixedly connected to the bottom, and the output shaft of the stepper motor 8 is fixedly connected to the belt pulley 9 on one side. Under this action, the stepper motor 8 can drive the belt pulley 9 to rotate. The belt pulley 9 is connected through a belt transmission. Under this action, when the belt pulley 9 on one side rotates, the belt pulley 9 on the other side can also rotate synchronously, so that the two threaded rods 10 can rotate at the same time. The bottom of the threaded rod 10 is fixedly connected to a bearing seat 14, and the bottom of the bearing seat 14 is fixedly connected to the inner wall of the placement box 1. Under this action, the bottom of the threaded rod 10 can be supported when it rotates, so that it will not easily vibrate to a large extent when it rotates, thereby improving the stability of the threaded rod 10 when it rotates. The surface of the threaded rod 10 is threadedly connected with a sleeve 1 1. The surface of the sleeve 11 is slidably connected to the inner wall of the placement box 1. The sleeve 11 is used in conjunction with the placement box 1. Under this action, when the sleeve 11 moves under the action of the thread on the surface of the threaded rod 10, the placement box 1 can guide the sleeve 11 so that it will not rotate under the action of the thread on the surface of the threaded rod 10 when moving, which effectively improves the stability of the sleeve 11 when rotating. A connecting frame 12 is fixedly connected to one side of the sleeve 11, and a placing mechanism 13 is installed on one side of the connecting frame 12. The placing mechanism 13 can place concrete test blocks that need to be cured or have been cured. Under the cooperation of the stepping motor 8 and the threaded rod 10, the placing mechanism 13 can drive the concrete test blocks to move, so as to facilitate the staff to take the concrete test blocks.It not only reduces the workload of the staff, but also improves the safety when taking concrete test blocks.

[0024] The protective mechanism 7 includes a blocking block 71, the surface of which is slidably connected to the inner wall of the placement shell 3, the bottom of the blocking block 71 is fixedly connected to a connecting rod 72, the other end of the connecting rod 72 penetrates to the bottom of the placement shell 3 and is slidably connected to the inner wall of the penetration point, the connecting rod 72 is a T-shaped structure design, the surface of the connecting rod 72 is fixedly connected to a compression spring 73, the other end of the compression spring 73 is fixedly connected to the bottom of the placement shell 3, under this action, the blocking block 71 can rotate the concrete test block to prevent the concrete test block from detaching from the surface of the placement shell 3 under the action of the ball 6, and when taking the concrete test block, the blocking block 71 can be pressed down to move it to the inner cavity of the placement shell 3, and then The concrete test block slides out from the surface of the placement shell 3. Under the action of the compression spring 73, after the concrete test block is moved out, the blocking block 71 can be moved back to its original position through the connecting rod 72 to block the concrete test block again. One side of the blocking block 71 is designed with an inclined structure. The surface of the blocking block 71 is slidably connected to the inner wall of the placement shell 3. Under this action, when the concrete test block is pushed to the surface of the placement shell 3, the blocking block 71 can automatically enter the inner cavity of the placement shell 3 under the action of the shape. When the concrete test block moves from the surface of the placement shell 3 to one side of the blocking block 71, the blocking block 71 will not move, thereby improving the blocking effect on the concrete test block.

[0025] The placement mechanism 13 includes a receiving plate 131, one side of which is rotatably connected to the inner cavity of the connecting frame 12, and both sides of the bottom of the connecting frame 12 are fixedly connected with positioning blocks 132, and the surface of the positioning block 132 is slidably connected to a blocking frame 133, and the surface of the blocking frame 133 is slidably connected to the receiving plate 131. The positioning block 132 is designed as a T-shaped structure, and the positioning block 132 and the blocking frame 133 are used in conjunction with each other. Under this function, when the staff needs to move the concrete test block through the receiving plate 131, the blocking frame 133 is pushed to contact with the receiving plate 131, so that the receiving plate 131 cannot rotate downward, thereby receiving the concrete test block. When the receiving plate 131 is not needed, the blocking frame 133 is moved to the bottom of the connecting frame 12 so that it is no longer in contact with the receiving plate 131, and the receiving plate 131 will rotate under the action of its own gravity to prevent the receiving plate 131 from blocking the placement box 1 from closing the door.

[0026] It is worth noting that the technical features such as the placement box 1, the maintenance mechanism 2 and the installation mechanism 4 proposed in this technical solution should be regarded as the prior art. The specific structure, working principle and possible control method and spatial layout method of these technical features can be selected according to the conventional methods in the field, and this technical solution will not be further elaborated.

[0027] Working principle: first, place the concrete test block to be cured on the top of the receiving plate 131, and then turn on the stepper motor 8. Under the action of the stepper motor 8, the sleeve 11 can be moved through the cooperation of the belt pulley 9 and the threaded rod 10, so that the sleeve 11 can drive the receiving plate 131 and the concrete test block on its surface to move through the connecting frame 12. When it moves to correspond to the placement shell 3, it directly pushes the concrete test block. Under the action of the shape of the blocking block 71, the blocking block 71 will move to the inner cavity of the placement shell 3. Then, under the action of the ball 6, the concrete test block moves to a suitable position on the surface of the placement shell 3. The concrete test blocks are placed in turn. After placement, the blocking frame 133 is moved to the bottom of the connecting frame 12, and rotated under the action of the gravity of the receiving plate 131 itself. Then the staff closes the door of the placement box 1 and opens the curing mechanism 2 to cure the concrete test block inside the placement box 1.
