Detailed Implementation

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0021] Reference Figures 1-3 The suspended traveling crane includes a boom 1. Four support assemblies 2 are fixedly connected to the outer wall of the boom 1. Each support assembly 2 consists of multiple connecting rods. The boom 1 and the support assemblies 2 are fixed together by multiple bolts. The support assemblies 2 are fixed to fixed plates 4 by welding. Four fixed plates 4 are fixedly connected to the top of each support assembly 2. Each fixed plate 4 is equipped with a moving mechanism. Multiple moving motors 5 are controlled by a synchronization system to drive synchronously. The moving mechanism uses rotating wheels 9 and guide rails 3 to move the boom 1 along the guide rails. The linear movement of the boom 1 includes a drive gear 7 rotatably connected to the side wall of the fixed plate 4. The drive gear 7 meshes with two driven gears 8. Both driven gears 8 are coaxially fixedly connected to rotating wheels 9. The outer walls of the two rotating wheels 9 abut against the outer walls of the guide rails 3. Two guide rails 3 are provided above the boom 1. The guide rails 3 are I-shaped. The outer walls of the rotating wheels 9 abut against the inner bottom of the guide rails 3. Multiple rotating wheels 9 are located at both ends of the guide rails 3 and are symmetrically arranged. The symmetrical arrangement of the rotating wheels 9 ensures the stability of the boom 1 during movement.

[0022] A reducer 6 is fixedly connected to the side wall of the leftmost fixed plate 4. A moving motor 5 is fixedly connected to the side wall of the reducer 6. The output end of the moving motor 5 is connected to the input end of the reducer 6. The output shaft of the reducer 6 passes through the fixed plate 4 and is rotatably connected to it. Its end is coaxially fixedly connected to the drive gear 7. The moving motor 5 drives the drive gear 7 through the reducer 6 to achieve power reduction and torque increase.

[0023] A winding motor 11 is fixedly connected to the end side wall of the boom 1. A transmission rod 12 is fixedly connected to the output end of the winding motor 11. The transmission rod 12 passes through the boom 1 and is rotatably connected to it. A winding wheel 13 is fixedly connected to the outer wall of the transmission rod 12. A fixed wheel 16 is fixedly connected to the boom 1. A fixed guide wheel 10 is rotatably connected to the boom 1. A wire rope 17 is wound around the outer wall of the fixed wheel 16. One end of the wire rope 17 is fixedly connected to the outer wall of the fixed wheel 16. The other end of the wire rope 17... The end is fixedly connected to the outer wall of the take-up reel 13. Two moving wheels 14 are provided below the boom 1. The two moving wheels 14 are fixedly connected to the hook 15. The wire rope 17 starts from the outer wall of the fixed wheel 16 and sequentially winds along the outer wall of the rear moving wheel 14, the outer wall of the fixed guide wheel 10, the outer wall of the front moving wheel 14, and finally wraps around the outer wall of the take-up reel 13. The take-up reel 13 drives the hook 15 to rise and fall by winding and unwinding the wire rope 17. The fixed guide wheel 10 changes the direction of force on the wire rope 17.

[0024] In this invention, the guide rail 3 is fixed to the top of the wall beforehand. Multiple moving motors 5 are started, which drive the driving gear 7 to rotate, causing the two driven gears 8 and the rotating wheel 9 to drive synchronously. The multiple pairs of rotating wheels 9 can drive the boom 1 and the lifted goods to move by rolling on the guide rail 3. The winding motor 11 is started, and the output end of the winding motor 11 drives the transmission rod 12 and the winding wheel 13 to rotate, so that the winding wheel 13 winds up or unwinds the wire rope 17, thereby driving the hook 15 to move up and down (during this process, the two moving wheels 14 move synchronously), thus realizing the lifting or unloading operation of the goods.
