The pulley guides the wire rope and supports the steel. One end of the reel is fixedly connected with a first motor, and the first motor rotates to drive the reel to rotate, so that the hook at the other end of the wire rope is driven to move vertically up and down, and the parts are moved. Hoist and lower.

The slewing support includes a large gear and an inner ring, the large gear is fixedly installed at the lower end of the upper vertical lifting device, and the inner ring is fixedly connected with the machining center.

The lower driving device includes a pinion and a second motor, the pinion is engaged with the bull gear (external meshing, and the output end of the second motor is fixedly connected to the pinion. When the second motor rotates, it drives the pinion to rotate Movement, the pinion and the bull gear are externally meshed, and the upper vertical hoisting device installed above the bull gear and the bull gear make a slewing motion together.

The beneficial effect of the utility model is that the lifting structure lifts and lowers parts by controlling the cylinder and the air motor through the switch, which is convenient for the maintenance personnel to maintain the machine tool alone, and does not need to find other equipment and personnel to assist in lifting heavy parts, thereby improving the maintenance efficiency.
