[0052] See also Figure 1 and Figure 7 As shown, the method for using the system of automatically pumping out and plugging the calcium carbide pot 2 and the plugging plate 3 based on the calcium carbide production process includes the following steps:

[0053] S1, after the calcium carbide is taken out of the furnace, the calcium carbide pot 2 filled with calcium carbide is mounted on the calcium carbide pot trolley 1 using a crane;

[0056] Multiple calcium carbide pot trolleys 1 are used to directly transport multiple calcium carbide pots 2 filled with calcium carbide to a cooling position to achieve a certain degree of cooling;

[0057] S3. After a certain cooling period, the automatic plugging and unplugging system of the electric stone pot is started;

[0058] S4, the automatic grabbing device automatically moves to the designated electric stone pot trolley 1, the output end of the automatic grabbing device is activated, and the plug board 3 is pulled out;

[0059] S4-1, the controller starts the positioner 16 on the designated electric stone pot trolley 1;

[0060] S4-2, the controller controls the driving unit of the manipulator trolley 5 to start, and the manipulator trolley 5 moves;

[0063] S5, putting the pulled out plug board 3 on the plug board 3 rack to facilitate the subsequent installation of the plug board 3 on the electric stone pot 2.

[0064] When the calcium carbide pot 2 needs to be unplugged from the plug-in board 3, the controller controls the positioner 15 on the calcium carbide pot trolley 1 to start, and at the same time, the controller controls the manipulator trolley 5 to start. The manipulator trolley 5 runs and runs to the calcium carbide pot 2 where the plug-in board 3 needs to be unplugged.

The controller controls the manipulator trolley 5 to stop moving and controls the manipulator 4 to run. The output end of the manipulator 4 can directly grab the grabbing mechanism, thereby pulling out the plug-in board 3.

[0065] See also Figure 7 As shown, during the entire operation process, the corresponding activation of the positioners 15 at different positions is used to pull out the electric stone pot plug-in plates at different positions, reducing manual operations.
