Description

Technical Field

[0001] The utility model relates to the technical field of elevators, in particular to an anti-settling device for a vertical elevator. Background Art

[0002] A vertical elevator is a fixed mechanical conveying equipment, mainly used for continuous vertical lifting of powdered, granular and small pieces of materials. It is suitable for feed mills, flour mills, rice mills, oil mills, starch mills, grain depots, port terminals and other places. There are many types of vertical elevators, such as vertical vibrating elevators and vertical bucket elevators.

[0003] When the elevator reaches the specified height, it will add or remove materials from the lifting plate. At this time, the load of the lifting plate changes. When the weight of the lifting plate decreases, the lifting plate is likely to rise due to the weight reduction. When the weight of the lifting plate increases, the lifting plate is likely to fall due to the weight increase. When the height of the lifting plate fluctuates, it is easy to cause a height difference between the shelf and the lifting plate, which is more dangerous when loading.

[0004] To this end, we propose a vertical hoist anti-settling device to solve the above problems. Utility Model Content

One end of the transmission shaft rotatably penetrates through the fixed plate and is in transmission connection with the rotating shaft on the same side through a second transmission mechanism.

[0010] Further, the first transmission mechanism includes two first belt pulleys, the two first belt pulleys are respectively coaxially and fixedly connected with the two rotating shafts, and the two first belt pulleys are in transmission connection through a synchronous belt.

[0011] Further, the bevel gear set includes a first bevel gear and a second bevel gear which are meshed with each other, the first bevel gear is coaxially and fixedly connected with the transmission shaft, and the second bevel gear is coaxially and fixedly connected with the bidirectional threaded rod.

[0014] Further, the support plate and the threaded block are rotatably connected through a coil spring.

[0015] Further, a clamping groove matching the support plate is arranged on the side wall of the lifting column.

[0017] By arranging the anti-settlement mechanism, the motor drives the two rotating shafts to rotate, the two rotating shafts drive the four transmission shafts to rotate, the transmission shafts drive the bidirectional threaded rod to rotate, the bidirectional threaded rod drives the two threaded blocks to move relatively, the two threaded blocks drive the two support plates to move, and the support plates deflect under the action of the inclined surfaces of the groove until the two support plates are inserted into the clamping grooves.

[0024] The present invention will be described in detail below with reference to the specific embodiments shown in the accompanying drawings. However, these embodiments do not limit the present invention, and any structural, methodological, or functional modifications made by a person skilled in the art based on these embodiments are all within the scope of protection of the present invention.

[0025] See also Figures 1 to 4 , a vertical hoist anti-settling device, comprising two lifting columns 1 and a lifting plate 2 on the hoist, wherein the lifting plate 2 is arranged between the two lifting columns 1. It should be noted that a slot 20 matching the support plate 11 is provided on the side wall of the lifting column 1;

[0026] The anti-settling mechanism 3 is used to prevent the lifting plate 2 from sinking. The anti-settling mechanism 3 includes two rotating shafts 4 that rotate and penetrate the lifting plate 2. The two rotating shafts 4 are connected to each other through a first transmission mechanism 5. Specifically, the first transmission mechanism 5 includes two first pulleys 15. The two first pulleys 15 are respectively coaxially fixedly connected to the two rotating shafts 4. The two first pulleys 15 are connected to each other through a synchronous belt transmission. The side wall of the lifting plate 2 is fixedly connected to a motor 6. The drive shaft of the motor 6 is coaxially fixedly connected to one of the rotating shafts 4. Fixed plates 7 are provided on the front and rear sides of the two lifting columns 1. The four fixed plates 7 are all fixedly connected to the lifting plate 2.

[0027] Through the above technical features, the motor 6 drives the two rotating shafts 4 to rotate, the two rotating shafts 4 drive the four transmission shafts 12 to rotate, the transmission shaft 12 drives the bidirectional threaded rod 9 to rotate, the bidirectional threaded rod 9 drives the two threaded blocks 10 to move relative to each other, and the two threaded blocks 10 drive the two support plates 11 to move. The support plates 11 are deflected under the action of the inclined surface of the groove 8 until both support plates 8 are inserted into the slot 20. At this time, when the lifting plate 2 increases the load, the lifting plate is prevented from falling under the support action of the lower support plate 11. When the lifting plate 2 reduces the load, the lifting plate 11 is prevented from rising under the support action of the upper support plate 11, thereby playing a good anti-settling effect on the lifting plate.

[0028] In this embodiment, a groove 8 is provided on the side of the fixing plate 7 close to the lifting column 1, and a two-way threaded rod 9 is rotatably connected in the groove 8. The two-way threaded rod 9 is externally threaded with two threaded blocks 10. It should be noted that the two threaded blocks 10 located outside the same two-way threaded rod 9 are provided with threaded holes that match the two-way threaded rod 9. The threads in the two threaded holes are rotated in opposite directions. The two threaded blocks 10 are both slidably connected to the inner side wall of the groove 8. The ends of the two threaded blocks 10 away from the bottom of the groove 8 are rotatably connected to a support plate 11. It should be noted that the support plate 11 and the threaded block 10 are rotatably connected by a coil spring. Inclined surfaces are provided on the upper and lower sides of the opening of the groove 8. The two support plates 11 respectively match the two inclined surfaces. The transmission shaft 12 is connected to the bidirectional threaded rod 9 through a bevel gear set 13. It is worth mentioning that the bevel gear set 13 includes a first bevel gear 16 and a second bevel gear 17 that mesh with each other. The first bevel gear 16 is coaxially fixedly connected to the transmission shaft 12, and the second bevel gear 17 is coaxially fixedly connected to the bidirectional threaded rod 9. One end of the transmission shaft 12 rotates through the fixed plate 7 and is connected to the rotating shaft 4 on the same side through a second transmission mechanism 14. Further, the second transmission mechanism 14 includes a second pulley 18 and a third pulley 19. The second pulley 18 is coaxially fixedly connected to the rotating shaft 4, and the third pulley 19 is coaxially fixedly connected to the transmission shaft 12. The second pulley 18 and the third pulley 19 are connected by a synchronous belt transmission.

[0029] Working principle: The two rotating shafts 4 are driven to rotate by the motor 6, and the two rotating shafts 4 drive the four transmission shafts 12 to rotate, and the transmission shaft 12 drives the bidirectional threaded rod 9 to rotate, and the bidirectional threaded rod 9 drives the two threaded blocks 10 to move relative to each other, and the two threaded blocks 10 drive the two support plates 11 to move, and the support plates 11 are deflected under the action of the inclined surface of the groove 8 until the two support plates 8 are inserted into the slot 20. At this time, when the lifting plate 2 increases the load, the lifting plate is prevented from falling under the support action of the lower support plate 11. When the lifting plate 2 reduces the load, the lifting plate 11 is prevented from rising under the support action of the upper support plate 11, thereby playing a good anti-settling effect on the lifting plate.
