The transfer car body 1 has a certain strength, and it carries the weight of the storage mechanism 2 and the PC mold table it transports; The car body 1 is raised and lowered; the traveling mechanism 4 can drive the transfer car body 1 and its upper storage mechanism 2, the lifting mechanism 3, and the PC mold table to be transported to make a linear motion back and forth along the track 7; the positioning The mechanism 5 is used in conjunction with the positioning device of the curing kiln body to accurately locate the relative position of the access machine and the curing kiln body; the height positioning mechanism 6 is used in conjunction with the floor height positioning blocks on the columns around the transfer car body 1 , to accurately locate the position where the storage mechanism 2 stops at the specified floor height; the pick-up mechanism 8 is installed at the end of the storage mechanism 2 close to the position of the maintenance kiln body, and it can flip and stretch the PC mold table through its own flipping block Into or out of the curing kiln kiln body.

The workflow is as follows:

Step 1: After the PC component is injected, it is carried by the PC mold table and runs to the end of the production line through the PC production line. At this time, the traveling mechanism 4 will move the transfer car body 1 to the position corresponding to the end of the PC production line, and the lifting mechanism 3 will store the mechanism 2 Descend to the bottom of the transfer car body 1. At this time, the working wheel 91 carrying the PC mold table of the storage mechanism 2 is in a straight line with the driving wheel of the PC production line, and the driving wheel of the PC production line continues to work, and the PC mold table is transported to the storage mechanism 2. On the working wheel 91 carrying the PC mold table on the top, the working wheel carrying the PC mold table on the storage mechanism 2 continues to work, and the PC mold table is moved to a position that is flush with the front and back of the storage mechanism 2, and now the traveling mechanism 4 starts to work , transport the PC mold table to the designated position of the curing kiln, rely on the positioning mechanism 5 to accurately locate the horizontal position of the PC mold table and the curing kiln, and at this time the lifting mechanism 3 starts to work and lifts the storage mechanism 2 and the PC mold table loaded to the specified position The position of the curing kiln floor height relies on the height positioning mechanism 6 to accurately locate the vertical position of the PC mold platform and the curing kiln, and relies on the fixing mechanism 14 and the transfer car body 1 to fix. At this time, the working wheel 91 carrying the PC mold table on the storage mechanism 2 starts to work, and under the action of the pick-up mechanism 8, the PC mold table is accurately sent into the designated curing kiln kiln body, so far the PC mold table is stored in the curing kiln. The process is completed;

Step 2: After the PC components are cured in the curing kiln, the access machine running mechanism 4 moves the access machine to the position corresponding to the curing kiln, and the positioning mechanism 5 is used to accurately locate the horizontal position of the PC mold table and the curing kiln. At this time, the lifting mechanism 3 starts to work and lifts the storage mechanism 2 to the floor height where the PC mold table is located, and relies on the height positioning mechanism 6 to accurately locate the vertical position of the storage mechanism 2 and the curing kiln, and relies on the fixing mechanism 14 and the transfer car body 1 fixed. This moment, the fetching mechanism 8 installed in the position of the storage mechanism 2 ends near the maintenance kiln body starts to work, and the PC mold table is taken out from the maintenance kiln body. Through the cyclical operation of the above steps, the mold table access machine can complete the process of storing and taking out the PC mold table from the curing kiln.
