This utility model discloses a connection structure and device for precast concrete components. The connection structure includes a connector and at least one opening groove on the outer edge of an end plate on the precast concrete component. The opening groove penetrates the upper and lower surfaces of the end plate, and the connector is embedded in the opening groove. The connection device includes two end plates located at the ends of adjacent precast concrete components, and also includes the connection structure. The opening grooves on the outer edges of the two end plates of the two precast concrete components are vertically aligned, and the two end plates are connected together by the connector embedded in the two vertically aligned opening grooves. This utility model has a simple structural design, enabling rapid and reliable connection of multiple precast concrete components.

The application discloses a covering machine AGV die changing system and a die changing method, and relates to the technical field of covering machines, which comprises a covering machine, a first in-out material die changing rack and a second in-out material die changing rack are arranged at the entrance and the exit of the covering machine respectively, a first stored edge warehouse and a second stored edge warehouse are arranged at the two sides of the first in-out material die changing rack respectively, a third stored edge warehouse and a fourth stored edge warehouse are arranged at the two sides of the second in-out material die changing rack, AGV guide rails are arranged between the second in-out material die changing rack, the first in-out material die changing rack, the first stored edge warehouse, the second stored edge warehouse, the third stored edge warehouse and the fourth stored edge warehouse, and an AGV die changing trolley moving along the AGV guide rails is further arranged, the system can realize the simultaneous in-out of the die through two die changing racks, the actual single-time die changing time is shortened to 30s, a plurality of stored edge warehouses are arranged, the taking time of the edge warehouse is reduced, and when the die warehouse increases, the AGV die changing trolley can also be used as a turnover vehicle.
