[0031] like Figure 1 As shown, the vertical lifting device according to an embodiment of the present invention includes a frame body 11, a lifting mechanism 12, a car 13, a counterweight component 15, and a safety net (not shown in the figure). The frame body 11 includes multiple frames 27 stacked together, with entrances and exits provided in both the bottom and top frames 27. The frame body 11 is provided with a car lifting guide rail 21 and a counterweight component lifting guide rail 26. The lifting mechanism 12 is located on the frame body 11. The car 13 includes a car frame 27, a hopper 410, and a hopper chain conveyor 46. The car frame 27 and the lifting mechanism 12 are connected. 2. The lifting mechanism 12 is adapted to drive the car frame 27 to rise and fall along the car lifting guide rail 21. The hopper chain conveyor 46 is provided on the car frame 27. The hopper 410 is provided on the hopper chain conveyor 46. The hopper chain conveyor 46 is adapted to convey the hopper 410 into the car frame 27 or to convey the hopper 410 out of the car frame 27. The counterweight component 15 is connected to the lifting mechanism 12. The counterweight component 15 is adapted to rise and fall along the counterweight component lifting guide rail 26. The rising and falling direction of the counterweight component 15 is opposite to that of the car 13. The safety protection net ring is provided on the periphery of the frame body 11.

[0032] According to the vertical lifting device of this utility model embodiment, the lifting mechanism 12 drives the car 13 to rise and fall on the frame body 11 to complete the layer-by-layer transportation of the distiller's grains. The counterweight component 15 rises and falls in the opposite direction to the car 13, reducing the energy consumption of the lifting mechanism 12. At the same time, the safety net strengthens the protective measures. In this way, manual handling of the distiller's grains is avoided, improving transportation efficiency and transportation safety.

[0033] Specifically, such as Figure 2 and Figure 3As shown, the main frame 11 includes: a car lifting guide rail 21, a limiter wire rope 22, a car upper limit mechanical switch 23, a car upper limit photoelectric switch 24, a lifting tank chain 25, a counterweight component lifting guide rail 26, a frame 27, a counterweight component polyurethane buffer 28, a car lower limit photoelectric switch 29, a car lower limit mechanical switch 210, and a car polyurethane buffer 211.

[0034] Specifically, such as Figure 6 As shown, the car 13 includes: a car frame 41, a safety linkage device 42, a guide rail oil can 43, a car guide shoe 44, a safety clamp 45, a hopper chain conveyor 46, a hopper guide device 47, a laser detection positioning switch 48, a car chain lifting lug 49, and a hopper 410.

[0035] Specifically, such as Figure 7 As shown, the counterweight component 15 includes: a counterweight frame 51, a counterweight block 52, a counterweight block fixing rod 53, a counterweight chain lifting lug 54, and a counterweight component guide shoe 55.

[0036] Depend on Figure 1 As shown, the main frame 11 is assembled from layers of frames 27, which facilitates installation and transportation. A safety net 15 is installed around the main frame 11 to strengthen protection.

[0037] In one embodiment, such as Figure 4 and Figure 5 As shown, the lifting mechanism 12 includes: a top frame 31; a drive shaft 32; a drive sprocket 33; a first lifting chain 34; a second lifting chain 35; a drive chain 36; a drive motor 37; a passive drive sprocket 38; a speed limiter 39; and a lifting polyurethane buffer 310.

[0038] Depend on Figure 4 As shown, the lifting mechanism 12 drives the transmission chain 36 via the transmission motor 37, which in turn drives the transmission main shaft 32 and the first lifting chain 34 and the second lifting chain 35 to move. The lower end of the first lifting chain 34 is connected to the car chain lug 49 on one side of the car, and the upper end is connected to the counterweight chain lug 54 of the counterweight component. The lower end of the second lifting chain 35 is connected to the car chain lug 49 on the other side of the car, and the upper end of the second lifting chain 35 passes around the passive transmission sprocket 38 and connects to the counterweight chain lug 54 of the counterweight component.

[0039] The polyurethane buffer 310 is mounted on the top frame 31 to buffer the car 13 and improve safety.

[0040] Driven by the transmission motor 37, the first lifting chain 34 and the second lifting chain 35 cause the car 13 and the counterweight 15 to move vertically up and down within the frame body 11. When the car body 13 moves upward, the counterweight 15 moves downward; when the car 13 moves downward, the counterweight 15 moves upward. This up-and-down motion lifts the hopper 410 from the bottom to the top and then back down, thus completing the conveying of the distiller's grains.

[0041] Optionally, the drive motor 37 is equipped with a frequency conversion function, which allows for smooth acceleration during startup, smooth deceleration and stopping during shutdown, and smooth and uniform operation during intermediate running.

[0042] Optionally, the drive motor 37 is also equipped with a braking device, which can lock the motor when it stops, and prevent the car from sliding or shifting downwards when the motor stops.

[0043] In one embodiment, the first lifting chain 34, the second lifting chain 35, and the transmission chain 36 are each equipped with a chain guard, which serves two purposes: first, to ensure safety, and second, to prevent dust from entering the sprocket and affecting the use of the chain.

[0044] It should be noted that a conveyor motor is installed below the hopper chain conveyor device 46, which can transport the incoming hopper 410 to the middle of the car body, or transport the hopper 410 out of the car body, reducing manual operation and improving transportation efficiency.

[0045] According to one embodiment of the present invention, the car 13 further includes a hopper guide device 47, which is disposed on the car frame 41 and has an flared shape facing outward from the car frame 41. The hopper guide device 47 is used to guide the hopper into and out of the car frame 41. It can be understood that the hopper guide device 47 can prevent the hopper 410 from deviating in position when being transported in the car 13.

[0046] According to one embodiment of the present invention, the hopper guide device 47 is provided with guide balls, which are adapted to roll and abut against the outer side wall of the hopper. In this way, the friction between the hopper guide device 47 and the hopper 410 is reduced, thereby reducing the wear of both and improving durability.

[0047] According to one embodiment of the present invention, the car 13 further includes a laser detection positioning switch 48. A set of laser detection positioning switches 48 is provided on both the front and rear sides of the car frame 41. The laser detection positioning switches 48 are used to detect the position of the hopper 410. For example, there is one set of laser detection positioning switches 48 at the front and one at the rear of the car 13. This serves two purposes: first, it determines that the hopper 410 has been positioned correctly when the hopper chain conveyor 46 is conveying the hopper 410; second, it ensures that the hopper 410 is in the middle position of the car body.

[0048] According to one embodiment of this utility model, the car 13 further includes a safety clamp 45, which is disposed on the car frame 41 and adapted to clamp the car lifting guide rail 21. For example, one safety clamp 45 is installed on each of the left and right sides of the car 13. In the event of a sudden situation such as a broken lifting chain or motor malfunction, the car body may fall. At this time, the speed limiter 39 on the top lifting mechanism 12 will lock the limiter wire rope 22 in the frame body 11. The limiter wire rope 22 tightens the safety clamp 45 through the safety linkage device 42, and the safety clamp 45 locks the car lifting guide rail 21, thereby avoiding the danger of the car body falling due to a sudden situation such as a broken lifting chain or motor malfunction. This further ensures the safety and reliability of the equipment.

[0049] According to one embodiment of this utility model, the car also includes a guide rail oil reservoir 43, which is disposed on the car frame 41 and adjacent to the car lifting guide rail 21. The guide rail oil reservoir 43 is used to add lubricating oil to the car lifting guide rail 21. The guide rail oil reservoir 43 contains lubricating oil, which can lubricate the car lifting guide rail 21 while the car 13 moves up and down, ensuring smoother up and down movement of the car body and extending the service life of the car lifting guide rail 21.

[0050] According to one embodiment of the present invention, the bottom of the frame body 11 is equipped with a car lower limit photoelectric switch 29 and a car lower limit mechanical switch 210, both of which are used to control the car 13 to stop descending; optionally, the top of the frame body 11 is equipped with a car upper limit mechanical switch 23 and a car upper limit photoelectric switch 24, both of which are used to control the car 13 to stop ascending.

[0051] Understandably, if either the lower limit photoelectric switch 29 or the lower limit mechanical switch 210 is triggered, the downward movement of the car 13 will stop. Similarly, if either the upper limit mechanical switch 23 or the upper limit photoelectric switch 24 is triggered, the upward movement of the car 13 will stop. The dual limit switch configuration is designed to ensure safe operation of the equipment even if one limit switch malfunctions, thus preventing accidents.

[0052] According to one embodiment of the present invention, a car polyurethane buffer 211 is installed at the bottom of the frame body 11, and the car polyurethane buffer 211 is located directly below the car 13; optionally, a counterweight polyurethane buffer 28 is installed at the bottom of the frame body 11, and the counterweight polyurethane buffer 28 is located directly below the counterweight 15.

[0053] like Figure 2 , Figure 3 As shown, the bottom of the frame body 11 is equipped with car polyurethane buffers 211 and counterweight polyurethane buffers 28. There are four car polyurethane buffers 211 installed directly below the car 13, and two counterweight polyurethane buffers 28 installed directly below the counterweight 14. In the event of a sudden situation such as a broken lifting chain, motor malfunction, or failure of the safety clamp 45, the impact of the car 13 and counterweight 14 on the ground can be reduced, further improving the safety and reliability of the equipment.

[0054] like Figure 7 As shown, the counterweight block 53 on the counterweight component 15 increases the weight of the counterweight component, ensuring that the weight of the counterweight component and the car body are consistent. The counterweight block fixing rod 53 is to prevent slight shaking or jumping when the counterweight component 15 moves up and down, so as to ensure the smooth operation of the counterweight component 15.

[0055] Optionally, four counterweight guide shoes 55 are installed on each of the left and right sides of the counterweight component 15. While the car 13 moves up and down, the counterweight component 15 also moves up and down within the frame body 11. The counterweight guide shoes 55 on the counterweight component 15 slide up and down in the counterweight lifting guide rail 26. This prevents the counterweight component 15 from swaying back and forth or left and right, ensuring that the counterweight component 15 moves smoothly up and down within the frame body 11.

[0056] According to one embodiment of the present invention, four car guide shoes 44 are respectively installed on both sides of the car frame 41. The car guide shoes 44 slide in the car lifting guide rail to prevent the car body from swaying back and forth and left and right, so that the car 13 runs smoothly up and down in the frame body 11.

[0057] According to one embodiment of the present invention, the weight of the car 13 and the weight of the counterweight component 15 are proportional to each other, so as to reduce the energy required by the drive motor 37 to lift the car 13 and the hopper 410, thereby achieving the effect of energy saving.

[0058] Finally, it should be noted that the above embodiments are only used to illustrate the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the embodiments, those skilled in the art should understand that various combinations, modifications, or equivalent substitutions of the technical solutions of the present invention do not depart from the spirit and scope of the technical solutions of the present invention and should be covered within the scope of the claims of the present invention.
