Description

Technical Field

[0001] The utility model relates to the technical field of concrete curing, in particular to a constant temperature and humidity curing box for concrete. Background Technique

[0002] Concrete is an indispensable construction material in the industrial construction field. During the use of concrete, a corresponding constant temperature and humidity curing box is needed to conduct constant temperature and humidity experiments on concrete test blocks to detect whether the various indicators of this batch of concrete meet the construction standards. However, there are still certain defects in the existing constant temperature and humidity curing boxes for concrete when in use;

[0003] For example, a constant temperature and humidity curing box for concrete with the publication number CN217318517U has chutes arranged at equal intervals on the support frame, which is convenient for adjusting the distance between the placement frames. Through the setting of the diversion seat, the constant temperature and humidity curing box has a recycling structure. Through the setting of the protection board, it is convenient to protect the control panel on the constant temperature and humidity curing box;

[0004] During the actual use of this kind of constant temperature and humidity curing box for concrete, when the interval of the concrete test block placement frame needs to be adjusted, it is necessary to first open the box door, take out the placement frame, and then insert it into the corresponding chute to complete. This not only has cumbersome operations, but also repeatedly opening and closing the box door will damage the constant temperature and humidity environment inside the box, resulting in inaccurate test results. At the same time, the filter plate at the bottom is easily blocked by concrete particles, resulting in poor water filtration;

[0005] In view of the above problems, it is urgent to innovate and design on the basis of the original constant temperature and humidity curing box equipment for concrete. Therefore, we have proposed a constant temperature and humidity curing box for concrete that can well solve the above problems. Content of the Utility Model

[0006] The purpose of the utility model is to provide a constant temperature and humidity curing box for concrete to solve the problems in the actual use of this kind of constant temperature and humidity curing box for concrete. When the interval of the concrete test block placement frame needs to be adjusted, it is necessary to first open the box door, take out the placement frame, and then insert it into the corresponding chute to complete. This not only has cumbersome operations, but also repeatedly opening and closing the box door will damage the constant temperature and humidity environment inside the box, resulting in inaccurate test results. At the same time, the filter plate at the bottom is easily blocked by concrete particles, resulting in poor water filtration.

[0007] To achieve the above purpose, the utility model provides the following technical solution: A constant temperature and humidity curing box for concrete, including a curing box body, a box door and a control screen are arranged on the end face of the curing box body, a plurality of vertically distributed placement frames are arranged inside the curing box body, and a filter plate is fixedly connected below the placement frames inside the curing box body through a mounting plate;

[0008] On one inner wall of the curing box body, a stabilizing plate is fixedly connected. One side of each placement rack is slidably connected to the stabilizing plate, and an adjusting component is arranged on the other side of the placement rack. The adjusting component includes two horizontal sliding grooves symmetrically formed on the side wall of each placement rack. A slider is slidably connected inside the horizontal sliding groove. Between the two sliders on both sides, adjusting rods are fixedly connected in a staggered manner. The cross positions of the two adjusting rods are rotatably connected through a rotating pin. On the side walls of the two rotating pins at the uppermost and lowermost positions at the middle intersection, connecting rods are fixedly connected. Two vertically distributed adjusting grooves are formed on the side wall of the curing box body. The two connecting rods pass through the corresponding adjusting grooves to the outside of the curing box body and are fixedly connected to a moving block. The positions of the two moving blocks are fixed and adjusted through a fixing component. By moving the two moving blocks on the outside of the curing box body up and down, the crossing angle between the adjusting rods can be changed, and then the distance between each placement rack can be adjusted;

[0009] Above the filter plate, a cleaning component for cleaning the concrete particles blocking its surface is provided.

[0010] Preferably, the fixing component includes a mounting block formed at one end of the moving block. A circular mounting hole is formed in the center of the mounting block, and a fixing bolt passes through the inside of the mounting hole. Two groups of threaded grooves corresponding to the two adjusting grooves are formed on the side wall of the curing box body. Each group of threaded grooves is arranged vertically and equidistantly. The fixing bolt is threadedly connected to one of the threaded grooves in the corresponding group.

[0011] Preferably, the cleaning component includes a driving motor fixedly connected to the outer end of the curing box body.

The bottom end of the cleaning block is closely attached to the top end of the filter plate. By driving the lead screw to rotate through the driving motor, the threaded sleeve rod and the cleaning block are driven to perform reciprocating translation, so as to clean the impurity particles blocking the surface of the top end of the stabilizing plate.

[0012] Preferably, two T-shaped protrusions are formed on one side of the placement rack. Two vertically parallel T-shaped grooves are formed on the side wall of the stabilizing plate. The two T-shaped protrusions are respectively slidably connected inside the T-shaped grooves. Through the sliding connection between the T-shaped protrusions and the T-shaped grooves, the stability of the placement rack during vertical movement can be ensured.

[0013] Preferably, a handle is fixedly connected to the side wall of the moving block. The handle is in a U-shaped frame structure, so that the user can move the moving block up and down by grasping the handle for adjustment.

[0014] Preferably, one outer wall of the curing box body is fixedly connected with a sealing box, one side of the sealing box is provided with a flip door, the sealing box covers the outside of two adjusting grooves, and the sealing box is used to maintain the sealed state inside the curing box body to prevent the opening of the adjusting grooves from affecting the internal environment.

At the same time, a cleaning assembly for cleaning the concrete particles blocked on the surface of the filter plate is arranged above the filter plate to ensure smooth water filtration. The specific content is as follows:

[0017] (1) By setting an adjusting assembly, the two moving blocks located outside the box body can be moved up and down. The change in the height of the moving blocks will drive the change in the cross angle between the adjusting rods, thereby adjusting the distance between the placement racks, that is, without opening the box door, thus ensuring the constant temperature and humidity environment inside the box body;

[0018] (2) By setting a cleaning assembly, the driving motor is used to drive the screw rod to rotate, so as to drive the threaded sleeve rod and the cleaning block to move back and forth, thereby cleaning the impurity particles blocked on the top surface of the stabilizing plate and ensuring smooth water filtration;
