AI Technical Summary

Technical Problem

In existing double-hoist single-girder cranes, the direction of the electric hoists is inconvenient to adjust, resulting in unstable connections, affecting lifting stability, and the spacing between the electric hoists is not easy to adjust, reducing their service life.

Method used

The direction of the electric hoist is adjusted by setting bearing seats, rotating shafts, transmission boxes, motors and gear systems. The spacing of the electric hoist is adjusted by using bidirectional screws and adjusting blocks. A U-shaped anti-collision frame is equipped to mitigate collisions, and support beams enhance overall stability.

Benefits of technology

It enables the electric hoist to be adjusted to correspond with the end of the workpiece, maintaining a vertical position, improving service life and lifting stability, reducing collision impacts on the electric hoist, and enhancing the overall rigidity of the equipment.

Abstract

This utility model discloses a double-hoist single-girder crane, including a main beam, with vertical beams provided on the left and right sides of the bottom end of the main beam. A connecting plate is provided on the main beam, and a bearing seat is provided at the bottom end of the connecting plate. A rotating shaft is rotatably provided at the bottom end of the bearing seat, and a transmission box is provided at the bottom end of the rotating shaft. A driven gear is provided on the rotating shaft. A mounting groove is provided on the rear side of the bottom end of the connecting plate, and a first motor is provided in the mounting groove. A driving gear is provided at the output end of the first motor. The output end of the second motor passes through the left end of the transmission box and connects to the left end of a bidirectional screw. Two sets of adjusting blocks are threaded on the bidirectional screw. The two sets of adjusting blocks slide in a sliding groove. Two sets of electric hoists are respectively installed at the bottom ends of the two sets of adjusting blocks, which facilitates the adjustment of the direction of the two sets of electric hoists according to the orientation of the longer ends of the item, thereby improving the lifting stability of the item.
