Description

Technical Field

[0001] This utility model relates to the field of powder box transfer technology, and in particular to a lifting device for powder boxes. Background Technology

[0002] The starter culture plays a crucial role in the brewing of baijiu (Chinese liquor). It is a saccharifying and fermenting agent used in the brewing process, typically cultivated from grains or beans through specific techniques. It is rich in microorganisms, such as molds and yeasts, which break down the starch and protein in the grains to produce sugars and amino acids, ultimately leading to fermentation and the production of alcohol and other flavor compounds.

[0003] After fermentation, the prepared koji blocks need to be pulverized into koji powder in a pulverizer. The koji powder is then stored and transported in koji powder boxes. Because the koji powder boxes are heavy, they need to be hoisted and transported within the workshop using an overhead crane. The method involves installing lifting lugs on the top of the koji powder boxes. Before hoisting, operators connect the hooks on the overhead crane to the lifting lugs, thus connecting the koji powder boxes to the crane. Finally, the koji powder boxes are hoisted by the crane. It is evident that this method requires manual insertion of the crane hooks through the lifting lugs on the koji powder boxes, resulting in low work efficiency and safety hazards.

[0004] The inventor of this application is dedicated to the research of intelligent brewing equipment. In 2020, they applied for a lifting device with publication number CN214456107U, which includes a lifting device frame. A rotatable hook and a power mechanism for driving the hook to rotate are located at the bottom of the lifting device frame. The hook is used to fix the workpiece being lifted. A pulley is provided on the lifting frame, and a wire rope connected to the lifting equipment is mounted on the pulley. A trolley is connected to the lifting device via the wire rope. When the trolley drives the lifting device down to the upper surface of the hopper, the power mechanism drives the hook to rotate, locking the hook with the hopper and completing the fixation of the hopper and the lifting device. However, this lifting device is used for lifting hoppers, where the top of the hopper is open, and the lifting device fixes the hopper by clamping. The object to be lifted in this application is a koji powder box, which is a sealed box structure. Therefore, due to the difference in the object being lifted, this lifting device is not suitable for lifting koji powder boxes. Utility Model Content

[0039] The following is in conjunction with the appendix Figures 1-9 The present invention will be further described below.

[0040] Example 1

[0041] In view of the technical problems existing in the background art, this utility model provides a lifting device for a powder box.

[0042] In the specific technical solution, refer to Figure 1 and Figure 2 The system includes a lifting frame 1, on which four lifting assemblies 2 are arranged in a matrix. Each lifting assembly 2 is used to lift one powder box 7. The lifting frame 1 is provided with a pulley seat 101, on which pulleys (not shown in the figure) are provided. The pulleys are connected to the lifting equipment by steel wire ropes (not shown in the figure). The lifting assembly 2 includes four square-arranged pivot assemblies 3 and a power assembly 4.

[0043] Specifically, refer to Figure 3 , Figure 5, Figure 7 and Figure 8 The transfer pin assembly 3 includes a transfer pin seat 301, within which a transfer pin 302 is vertically and movably disposed. A triangular support block 303 is provided at the end of the transfer pin 302 below the transfer pin seat 301. The support block 303 has a flat structure and is used for contact connection with the powder box 7. (Refer to...) Figure 9 The top of the powder box 7 is provided with an elongated hole. The support block 303 of the pivot pin 302 can pass through the elongated hole 701 of the powder box. After the support block 303 is inserted into the elongated hole 701, the support block 303 is rotated 90° and can be locked into the elongated hole 701, thus completing the connection between the lifting frame 1 and the powder box 7.

[0044] To reduce the number of power components 4, this embodiment uses one power component to drive two pivots to rotate synchronously. Specifically, refer to... Figure 2 and Figure 3 Two pivot pins 302 on the same side are connected by a connecting rod 304. The fixed end of the power assembly 4 is connected to the lifting frame 1. The movable end of the power assembly 4 is connected to the middle of the connecting rod 304 through a connecting arm 401. The power assembly 4 is an electric cylinder.

[0045] Working principle: When it is necessary to hoist the powder box 7, the lifting frame 1 gradually moves towards the powder box 7 from above. At this time, the pivot pin 302... Figure 7 As shown, the support block 303 is parallel to the pivot pin seat 301. During the continuous descent of the lifting frame 1, the support block 303 extends into the elongated hole 701 of the powder box. After the support block 303 is fully extended into the elongated hole 701, the power component 4 extends. The power component 4 drives the connecting rod 304 to move through the connecting arm. The connecting rod 304 drives the pivot pin 302 to rotate 90°. At this time, the support block 303 is as follows: Figure 8 As shown, the support block 303 is perpendicular to the pivot seat 301, and the support block 303 is also perpendicular to the elongated hole 701. At this time, the support block 303 is confined within the elongated hole 701, thus completing the connection between the lifting device assembly 2 and the powder box 7.

[0046] As can be seen from the above structure and working principle, the lifting device of this utility model can complete the automatic installation and lifting of the powder box without human intervention, which improves production efficiency, reduces the intensity of manual labor, and also reduces safety hazards.

[0047] To further improve the intelligence of the equipment and detect the contact between the lifting device assembly 2 and the powder box 7 in real time, thereby guiding the rotation of the pivot pin, this embodiment also includes a detection component 5.

[0048] Specifically, refer to Figure 5 and Figure 6The detection assembly 5 includes a detection shaft 501 vertically arranged beside the pivot pin 302. The detection shaft 501 is movably connected to the lifting frame 1. A spring 502 is arranged on the outer side of the detection shaft 501. The spring 502 can drive the detection shaft 501 to move downward. A first sensor 503 matching the detection shaft 501 is arranged beside the detection shaft 501. When the detection shaft 501 is lifted by the powder box 7, the top of the detection shaft 501 is flush with the first sensor 503.

[0049] Working principle: Refer to Figure 6 The lifting frame 1 gradually approaches the toner box 7 from above. The bottom of the detection shaft 501 first contacts the top of the toner box 7. During the gradual approach, the toner box 7 applies an upward force to the detection shaft 501, and the spring 502 on the outside of the detection shaft 501 is compressed. The detection shaft 501 moves upward synchronously with the toner box 7. After rising, the detection shaft 501 is detected by the first sensor 503. The first sensor 503 feeds the signal back to the central control system, indicating that the toner box 7 and the lifting assembly 2 are tightly fitted and the next action can be carried out, that is, driving the pivot pin 302 to rotate to realize the connection between the toner box and the lifting assembly.

[0050] As can be seen from the above structure and working principle, the detection component of this utility model can detect the contact between the lifting device component and the powder box in real time, thereby guiding the rotation of the pivot pin to realize the connection between the powder box and the lifting device component, which greatly improves the automation level of the equipment and improves work efficiency.

[0051] Reference Figure 3 In this embodiment, a second sensor 102 and a third sensor 103 are also provided on the lifting frame 1 to detect the beginning and end states of the rotation of the pivot pin 302, thereby enabling real-time detection of the pivot pin's rotation. To facilitate wire harness storage, this embodiment also includes a wire reel (not shown in the figure) on the lifting frame 1. For ease of installation of the powder box and the lifting frame, refer to... Figure 1 and Figure 4 Therefore, in this embodiment, a guide plate 104 is also provided at the bottom of the lifting frame 1, and the lower part of the guide plate 104 is a sloping structure.

[0052] Example 2

[0053] During the transfer of the powder box 7, if the electric cylinder malfunctions or human error causes the pivot pin 302 to rotate, the powder box 7 will fall off the lifting assembly, causing damage to the equipment and potentially leading to a safety accident. Therefore, to address this problem, based on Embodiment 1, this embodiment also includes a locking assembly to prevent the pivot pin 302 from rotating during lifting.

[0054] Specifically, refer to Figure 3 , Figure 7 and Figure 8 The locking assembly includes a locking block 6 set on the top of the detection shaft 501, and a circular support 305 set on the pivot pin 302 above the pivot pin seat 301. The support 305 is horizontally spaced with protrusions 306. When the powder box 7 is lifted, the detection shaft 501 is lowered, and the locking block 6 and the protrusions 306 are at the same horizontal position. The locking block 6 is engaged between adjacent protrusions 306.

[0055] Working Principle: As described in Example 1, during the installation of the lifting assembly 2 and the powder box 7, the spring 502 on the outside of the detection shaft 501 is compressed, and the detection shaft 501 moves upward synchronously with the powder box 7. After the lifting assembly 2 and the powder box 7 are installed, the lifting equipment lifts the powder box 7 off the ground, and under the action of the spring 502, the detection shaft 501 moves downward to reset. After the detection shaft 501 descends, the locking block 6 set at the top of the detection shaft 501 is at the same horizontal position as the support 305, and the locking block 6 is located between adjacent protrusions 306. The detection shaft 501 limits the support 305, restricting the rotation of the support 305, which in turn restricts the rotation of the pivot pin 302 connected to the support 305. This prevents the powder box from detaching from the lifting assembly, protects the powder box, and improves safety.

[0056] As can be seen from the above structure and working principle, the locking component of this utility model can lock the turning pin during the hoisting of the powder box, thereby preventing the powder box from detaching from the hoisting device, protecting the powder box and improving safety.

[0057] The above specific embodiments further illustrate the purpose, technical solution and beneficial effects of this utility model. It should be understood that the above are only specific embodiments of this utility model and are not intended to limit the scope of protection of this utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the scope of protection of this utility model.
