Background
In the standard of concrete physical mechanical property test, the concrete sample has higher maintenance requirement regulation, which is embodied as follows: 1. the concrete sample is prevented from being shocked and impacted in the maintenance process so as to avoid the segregation and damage of the test piece; 2. the temperature requirement of the curing room is 20 +/-3 ℃, and the humidity requirement is 90%; 3. the maintenance age is 1 day, 3 days, 7 days, 28 days, 56 days or 60 days, 84 days or 90 days, 180 days and the like. Curing of concrete samples generally requires that curing be performed in a curing room. At present, a common curing room is a closed space and is matched with a goods shelf, an air conditioner and a humidifier for use, and although the curing requirement can be met, the following defects still exist: 1. manually stacking concrete samples, wherein the doors need to be opened and closed ceaselessly, so that the environment in a curing room is greatly influenced; 2. the manual stacking of the concrete samples not only needs to consume larger manpower, but also has more uncertainty compared with a mechanical stacking mechanism in manual operation, and is difficult to ensure the stable movement and the stable placement of the concrete samples; 3. the inner cavity of the maintenance room is a high-temperature high-humidity environment which is not an ideal working environment of the electrical components, and circuit faults are easy to occur if the electrical components are located in the maintenance room for a long time to work. Therefore, the automatic stacking device for the concrete samples is suitable for a curing room.
