AI Technical Summary
The existing center-distribution variable frequency gantry crane bridge top mounting bracket device cannot adjust the height, which means that when the car top height exceeds 2550mm, the gantry crane body needs to be raised, increasing production costs and reducing work efficiency.
An installation bracket device including a motor, drive shaft, transmission gear, lead screw, and lifting adjustment block is designed. The motor drives the transmission system to adjust the rotation of the lead screw, thereby achieving flexible adjustment of the bracket height. The locking block and connecting plate work together to achieve quick installation and disassembly.
This allows for flexible adjustment of the bracket height without increasing the height of the gantry crane body, improving work efficiency and connection stability while reducing production costs.
