AI Technical Summary
During the movement of the annealing furnace trolley, the equipment failure rate is high due to misalignment of the plug and socket. This is mainly caused by the offset between the steel wheel and the rail, as well as the vibration of the trolley, which causes the plug to go beyond the docking range of the socket.
A low-failure-rate annealing furnace trolley was designed, employing a T-shaped plug and a horizontally movable socket structure. Combined with an alignment component and a flexible arm, it ensures that the plug can still align with the socket when the trolley sways and vibrates. The accurate docking of the plug and socket is achieved through the guiding action of the alignment roller and guide plate.
It effectively reduces equipment failure rate, avoids collisions between plugs and sockets, and improves equipment reliability and stability.
