The bottom surface of the reinforcement plate 4 is fixedly connected to a ring track 8. The inside of the ring track 8 is slidably connected to a plurality of sliding blocks 9. The bottom surfaces of the plurality of sliding blocks 9 are commonly fixedly connected to a lifting square plate 10. The bottom surface of the lifting square plate 10 is hinged with a hook 12 through a plurality of pin shaft connection seats 11. The upper surface of the reinforcement plate 4 is fixedly connected to an adjusting cylinder 7. The inner top wall of the adjusting cylinder 7 is fixedly connected to a reduction motor 13. The output of the reduction motor 13 The end is fixedly connected with a rotating cylinder 14, the bottom end of the rotating cylinder 14 passes through the adjusting cylinder 7 and the reinforcement plate 4 in sequence and extends to the bottom of the reinforcement plate 4, the bottom end of the rotating cylinder 14 is fixedly connected with a reinforcement round block 15, the outer surface of the reinforcement round block 15 is fixedly connected with a plurality of driving connecting blocks 16, the bottom surface of each driving connecting block 16 is fixedly connected to the upper surface of the lifting square plate 10, the reduction motor 13 adopts a high-power reduction motor, which has the characteristics of low speed, large torque and wide application, thereby ensuring the normal use of the device.

[0018] By using the reinforcement plate 4, the annular track 8, the sliding block 9, the reduction motor 13, the driving connecting block 16 and the lifting square plate 10 in coordination, the rotation of the rotating cylinder 14 can be used to drive the reinforcement block 15, the driving connecting block 16 and the sliding block 9 to rotate in the annular track 8, thereby driving the lifting square plate 10 and the parts to rotate, and the orientation of the parts after lifting can be adjusted without manual manipulation, which is convenient for the staff to perform adjustment operations and to perform maintenance on the straightening machine, ensuring the safety during maintenance and lifting, and having the advantage of better use effect, solving the problem that after using the lifting device to lift some parts, the orientation after lifting needs to be adjusted to facilitate maintenance. Generally, the parts are rotated slowly by manual manipulation. Since the parts are heavy, multiple people are required to cooperate during adjustment, and the parts are located at a high position after lifting, which is not convenient for adjustment operations, thereby improving practicality.

[0019] Furthermore, two mounting plates 2 are fixedly connected to the bottom surface of the overhead crane 1 , and a plurality of mounting holes 3 are formed on the outer surface of each mounting plate 2 .

[0024] Furthermore, an anti-collision plate 18 is fixedly connected to the bottom surface of the hoisting square plate 10 , and the anti-collision plate 18 is located between the plurality of hooks 12 .
