Based on the embodiments in the implementation mode, other embodiments obtained by those skilled in the art without creative work are all within the protection scope of the present invention.

[0019] Example

[0020] Please refer to Figure 1 - Figure 4 As shown, the utility model provides a suspended electric hoist, including a cross beam 1, the cross beam 1 is an I-shaped as a whole, a front-to-back symmetrical guide rail 2 is opened inside the bottom plate of the cross beam 1, a front-to-back symmetrical clamping groove 3 is opened outside the bottom plate of the cross beam 1, a through groove 7 is opened on the top of the vertical plate of the cross beam 1, a transition wheel 12 is connected to the bottom of the winder 10 through a steel wire rope 11, a rotatable connecting frame 13 is connected to the bottom of the transition wheel 12, and a moving assembly includes a sliding frame 4, a first motor 5, a walking wheel 6, a cross bar 8, and a nut 9. The crossbeam 1 is provided with a sliding frame 4, and a left-right symmetrical crossbar 8 is passed through the upper end of the sliding frame 4. A nut 9 is screwed on the end of the crossbar 8 to prevent the sliding frame 4 from falling off. A first motor 5 with a running wheel 6 is provided inside the sliding frame 4. The sliding frame 4 is engaged with the card slot 3 to enhance the stability of the sliding frame 4. The running wheel 6 is clamped on the guide rail 2. A rotating sleeve 19 is sleeved on the crossbar 8. The rotating sleeve 19 is in the through slot 7. The crossbar 8 passes through the rotating sleeve 19. The rotating sleeve 19 can rotate so that the crossbar 8 can move smoothly.

[0021] When adjusting the position of the sliding frame 4, the first motor 5 is controlled to rotate, and the first motor 5 rotates to drive the walking wheel 6 to move in the guide rail 2, thereby changing the position of the sliding frame 4. At the same time, the rotating sleeve 19 rotates in contact with the bottom surface of the through groove 7, so that the cross bar 8 and the nut 9 rotate accordingly. When the sliding frame 4 moves, the winder 10 and the wire rope 11 are driven to move accordingly, thereby changing the position of the transition wheel 12 and the connecting frame 13.

[0022] like Figure 1 - Figure 4As shown, a moving component is installed on the crossbeam 1, and a winder 10 is arranged below the moving component. The winder 10 mainly includes a winding shaft and a power component. The power component drives the winding shaft to rotate to reel in and release the wire rope 11. A connecting frame 13 is arranged below the winder 10. A rectangular groove 14 is opened on the connecting frame 13. The rectangular groove 14 is arranged to provide a passing space for a rotating arc plate 18. A hook 15 is formed on the lower end surface of the connecting frame 13. The hook 15 is composed of two hook plates and a gap is left in the middle. The function of the gap is the same as that of the rectangular groove 14. A second motor 16 with a rotating shaft is arranged on the side of the hook 15, and the rotating shaft passes through the hook 15. A rotating arc plate 18 is arranged between the hooks 15, and the rotating arc plate 18 is fixedly connected to the rotating shaft. A driving controller 17 is arranged above the second motor 16;

[0023] When hanging the connecting rope, the second motor 16 is controlled to rotate by the driving controller 17, driving the rotating shaft to rotate, thereby driving the rotating arc plate 18 to rotate in different directions and with different amplitudes, so as to achieve the function of blocking the opening of the hook 15 or pushing the hanging rope out of the hook 15;

[0024] Specific working principle:

[0025] When using the device, firstly, the driving controller 17 is used to control the second motor 16 to rotate, drive the rotating shaft to rotate, and thus drive the rotating arc plate 18 to rotate clockwise, so that the rotating arc plate 18 is separated from the hook 15, and there is a gap between the two, and the connecting rope is hung in the hook 15, and then the driving controller 17 is controlled to control the second motor 16 to rotate in the opposite direction, drive the rotating shaft to rotate, and thus drive the rotating arc plate 18 to rotate counterclockwise, and rely on the rotating arc plate 18 to block the opening of the hook 15, and then control the first motor 5 to rotate, and the first motor 5 rotates to drive the walking wheel 6 to walk in the guide rail 2, and then the first motor 5 is controlled to rotate. The position of the sliding frame 4 is changed, and the rotating sleeve 19 is rotated in contact with the lower bottom surface of the through groove 7, so that the cross bar 8 and the nut 9 rotate accordingly. When the sliding frame 4 moves, the winder 10 and the wire rope 11 are driven to follow the movement, thereby changing the position of the transition wheel 12 and the connecting frame 13, thereby driving the hook 15 to move, and moving the object. After the movement is completed and the object falls to the ground, the drive controller 17 is controlled to control the second motor 16 to rotate, driving the rotating shaft to rotate, thereby driving the rotating arc plate 18 to rotate clockwise. At this time, the convex back of the rotating arc plate 18 contacts the connecting rope, and the connecting rope is pushed out of the hook 15.

[0026] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only preferred examples of the utility model and are not used to limit the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, which fall within the scope of the utility model to be protected.
