This utility model relates to the field of mechanical engineering, and more particularly to a protection device for a gantry dual-drive synchronous motion system with adjustable margin. The dual-drive synchronous mechanism consists of two transmission mechanisms, each containing a dual-axis motor, lead screw, pulley, and belt, providing power to the crossbeam. The crossbeam moving mechanism includes a crossbeam and a base, with lead screws connected to both ends of the crossbeam. Position sensors are installed on the crossbeam to detect the relative height of the two ends to ensure synchronization. The protection mechanism includes a limiting component and a tensioning component. The tensioning component is used to adjust the tension of the transmission belt, achieving adjustable margin to adapt to different working conditions. The limiting component not only restricts the movement range of the synchronous pulley, but its limiting position is also adjustable, thereby setting the allowable working range margin of the synchronous pulley. This invention ensures the motion synchronization of the gantry system through position sensor feedback and dual margin adjustment, and improves the reliability and adaptability of the system by protecting key components through limiting.

The at least one lifting assembly further comprises a first connecting rod and a plurality of first brackets, the plurality of first brackets are arranged at intervals along the extension direction of the first stand column, the first ends of each first bracket are connected together through the first connecting rod, and the second ends of the first brackets are used for supporting products to be moved; each first bracket is rotationally connected to the side wall of the first stand column and can rotate the second end of the first bracket around the rotation center thereof between a first supporting position and a non-supporting position under the action of an external force. The transfer type lifting device of the application has the advantages of simple structure, easy installation and high lifting position accuracy.

The application relates to the field of rubber product detection, in particular to a position adjusting device for rubber product detection, which comprises a rack, a driving block, a driving mechanism and an adjusting piece. The rack comprises a support, a first supporting plate and a sliding block. The sliding block is matched with a T-shaped column arranged on the support through a T-shaped groove, can be adjusted in the vertical direction, and is fastened by a positioning screw. The driving block is abutted with a disc. The disc drives the driving block to rotate. Power is transmitted to the adjusting piece through the driving mechanism (comprising a driving wheel, a driven wheel and a transmission belt). In addition, a tensioning wheel capable of horizontally sliding is arranged, which is used for adjusting the tension of the transmission belt. Positioning grooves are arranged on the driving wheel, the driven wheel and the tensioning wheel, so that the transmission belt is prevented from falling off. The device realizes power transmission through the abutment of the disc and the driving block, reduces the hardware cost, the tensioning wheel can adjust the tension of the transmission belt in real time, ensures transmission accuracy, improves equipment stability and adaptability.
