Description

Technical Field

[0001] This utility model relates to the technical field of copper stack transfer equipment, specifically a cantilever heavy-duty hoist and its transfer equipment. Background Technology

[0002] In the metallurgical industry, the transfer of copper stacks is a crucial step in the production process, widely used in raw material handling, process coordination, and finished product warehousing. With increasing automation, traditional forklift or manual transfer methods are gradually being replaced by automated equipment. Currently, truss-type hoists are commonly used in the industry for vertical and horizontal transfer of copper stacks. However, this type of equipment has significant technical drawbacks: firstly, the truss structure needs to cover the entire travel distance, requiring a large footprint and demanding strict factory layout requirements, which is detrimental to the planning of compact production lines; secondly, the overall structure is complex, involving multiple sets of guide rails, support beams, and transmission systems, resulting in high manufacturing, installation, and maintenance costs and poor economic efficiency. Therefore, a cantilever heavy-duty hoist and its transfer equipment are proposed. Utility Model Content

Each lifting component includes a sprocket cover mounted on the top of the column. A driven sprocket is installed inside the sprocket cover. A lifting chain is provided inside the column. The two ends of the lifting chain pass around the driven sprocket and the synchronization component, respectively, and extend out of the column. Both ends of the lifting chain are connected to a lifting frame through end caps. The lifting frame and the column are in a movable fit and move up and down along the height direction of the column.

[0006] The support assembly, connected to two lifting assemblies, is used to support the copper stack;

[0007] The drive assembly includes an active motor disposed on the side of one of the columns.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] The heavy-duty hoist of this application adopts a cantilever structure design. Compared with the conventional truss structure, its overall layout is compact and occupies a small area, making it particularly suitable for space-constrained working environments. It effectively improves the adaptability and layout flexibility of the equipment in narrow areas. In addition, it adopts a single cantilever fork design.

[0027] Specifically, the two columns 1 are arranged side by side and vertically. When the lifting component 2 moves up and down along the surface of the column 1, it can ensure the consistency of the movement direction of the two lifting components 2 and avoid the phenomenon of the distance between the two lifting components 2 changing, thereby ensuring the stability and synchronization during the lifting process.

[0028] Synchronization component 5, with its two ends connected to two lifting components 2 respectively, ensures the consistency of the two lifting components 2 during the lifting process;

[0029] Specifically, the two ends of the synchronization component 5 are respectively engaged with the two lifting components 2. When the synchronization component 5 is running, it can drive the two lifting components 2 located at both ends of the synchronization component 5 to move in the same direction, ensuring the consistency of their movements.

[0030] Support assembly 3, connected to two lifting assemblies 2, is used to support the copper stack;

[0031] Specifically, the two lifting components 2 provide certain support for the supporting component 3, which can ensure the smooth stacking of copper stacks.

[0032] The drive component 4 is mounted on one of the columns 1 and connected to the end of the synchronization component 5. The drive component 4 drives the synchronization component 5 to operate, thereby driving the two lifting components 2 to rise and fall synchronously, ensuring the synchronicity of the support component 3 when it rises and falls.

[0033] Please see Figure 1 In one embodiment, preferably, a base plate 6 is installed at the bottom of the column 1, and a plurality of threaded connecting rods are installed on the base plate 6, with the plurality of threaded connecting rods extending from the upper surface of the base plate 6 to the lower surface of the base plate 6. Support frames 7 are installed on both sides of the upper surface of the base plate 6 on the column 1, and the support frame 7 is composed of two support plates, with a certain space reserved between the two support plates.

[0034] Please see Figure 2-3 In one embodiment, preferably, the synchronization component 5 includes a drive shaft 501, which is disposed between two columns 1. The end of the drive shaft 501 passes through a bearing seat 502 connected to a support frame 7 and a gasket 503 is installed at its end. The outer circumferential surface of the drive shaft 501 is fitted with a drive sprocket 504 located inside the support frame 7. Further, there are four bearing seats 502, which are arranged in groups of two. Each group of bearing seats 502 is connected to one support frame 7, and the two bearing seats in the group are connected to two support plates on the support frame 7. Each bearing seat has an inner ring, which is fixedly connected to the end of the drive shaft 501. This inner ring can support the drive shaft 501 without affecting its rotation. Two drive sprockets 504 are fixedly installed on the outer circumferential surface of the drive shaft 501, and the two drive sprockets 504 are located inside the two support frames 7. The interior of the support frame 7 has space for the drive sprockets 504 to rotate.

[0035] Please see Figure 3-5In one embodiment, preferably, the lifting assembly 2 includes a sprocket cover 201 mounted on the top of the column 1. A driven sprocket 202 is installed inside the sprocket cover 201. A lifting chain 203 is provided inside the column 1. Both ends of the lifting chain 203 pass around the driven sprocket 202 and the driving sprocket 504, respectively, and protrude outside the column 1. Both ends of the lifting chain 203 are connected to the lifting frame 205 through end caps 204. The lifting frame 205 is movably fitted with the column 1 and moves along the height direction of the column 1. In the lifting motion, the sprocket cover 201 is fixedly installed on the top of the column 1, and a driven sprocket 202 is installed inside the sprocket cover 201. The driven sprocket 202 can rotate inside the sprocket cover 201, which provides support for it and covers the driven sprocket 202, providing a certain degree of protection and preventing its rotation from being interfered with by the outside. In addition, the two ends of the lifting chain 203 pass over the driven sprocket 202 and the driving sprocket 504 respectively and are inserted into the upper and lower surfaces of the lifting frame 205, and then... End 204 is connected to the lifting frame 205. The lifting chain 203 meshes with the driven sprocket 202 and the driving sprocket 504 for transmission. End 204 includes a threaded rod 2041 connected to the end of the lifting chain 203. The end of the threaded rod 2041 away from the lifting chain 203 passes into the interior of the lifting frame 205 and is fitted with a threaded sleeve 2042. A compression spring 2043 is fitted on the outer circumferential surface of the threaded rod 2041. When assembling the lifting chain 203 and the lifting frame 205, the end of the threaded rod 2041 is first inserted into the lifting frame. Inside 205, a compression spring 2043 and a threaded sleeve 2042 are sequentially inserted. By rotating the threaded sleeve 2042, the compression spring 2043 is continuously compressed, thereby applying a preload to the connection between the lifting frame 205 and the lifting chain 203. The compression spring 2043 provides continuous elastic tension under compression, which not only increases the reliability of the connection but also improves the smoothness of the operation of the lifting frame 205. In addition, an anti-disengagement pin 2044 is installed at the end of the threaded rod 2041 to prevent the threaded sleeve 2042 from disengaging from the threaded rod 2041.

[0036] Please see Figure 2 In one embodiment, preferably, the side wall of the column 1 is provided with a guide groove 11, and a plurality of guide wheels 206 located in the guide groove 11 are installed on the lifting frame 205. Further, there are two guide grooves 11, which are located on opposite sides of the column 1, to provide a moving path for the plurality of guide wheels 206 installed on the lifting frame 205, so as to avoid the lifting frame 205 from deviating during the lifting process.

[0037] Please see Figure 2In one embodiment, preferably, the support assembly 3 includes a crossbeam 301, both ends of which are connected to the lifting frame 205 via a fixing frame 302. A fork tooth 303 is installed on the crossbeam 301. The crossbeam 301 and the fixing frame 302 are connected by bolts. Both fixing frames 302 are connected to two lifting frames 205 by bolts. The fork tooth 303 has a flat upper surface, which can provide stable support for the copper stack.

[0038] Please see Figure 3 In one embodiment, preferably, the drive assembly 4 includes an active motor 401, which is disposed on the side of one of the columns 1. A first sprocket 402 is installed at the output end of the active motor 401, and a second sprocket 403 is installed at the end of the drive shaft 501 near the column 1. The first sprocket 402 and the second sprocket 403 are connected by a chain 404. Furthermore, the active motor 401 drives the first sprocket 402 connected to its output end to rotate. The first sprocket 402 drives the chain 404 to move through meshing transmission. The chain 404 transmits power to the second sprocket 403, causing it to rotate accordingly. Since the second sprocket 403 is connected to the end of the drive shaft 501, it drives the drive shaft 501 to rotate synchronously, thereby achieving efficient power transmission.

[0039] A transfer device includes a cantilever heavy-duty hoist, and further includes several sets of chain conveyors. The cantilever heavy-duty hoist is positioned between two sets of chain conveyors. The sets of chain conveyors are segmented, and their movement will not interfere with each other. Each chain conveyor includes a support frame on which two sets of chain conveyors are mounted. The two sets of chain conveyors are used to transport copper stacks. The chain conveyors can transport copper stacks in two directions. The chain conveyor is existing technology and will not be described in detail here. A fork tooth 303 is located between the two sets of chain conveyors in one of the chain conveyors, and the distance between the two sets of chain conveyors is greater than the width of the fork tooth 303.

[0040] The working principle and usage process of this utility model are as follows: During the copper stack transfer process, the control system completes the system scheduling and route arrangement between each workstation. The hoist and chain machine work together to achieve automatic lifting, shifting, and returning of the copper stack. This, combined with the robotic arm, completes the automatic stacking and transfer of copper plates, improving the overall automation level and operational efficiency, and reducing manual intervention and operational risks. This control system is existing technology and will not be elaborated upon here. First, the robotic arm grabs copper plates from other workstations and places them on the chain machine where the fork tooth 303 is located. The chain machine remains stationary, with its chain assembly not moving, while chain machines at other workstations continue operating without interference. The robotic arm continuously picks up copper plates and places them onto the chain machines, forming stacks of different sizes. When stacks of copper from other workstations need to pass through this chain machine to reach their respective workstations, the drive motor 401 is activated. Its output drives the first sprocket 402 to rotate, which in turn drives the transmission shaft 501 to rotate via the first sprocket 402, chain 404, and second sprocket 403. 1. The drive shaft 501 rotates, and during this rotation, it drives the drive sprocket 504 to rotate synchronously. The drive sprocket 504 pulls the lifting chain 203. Since the lifting chain 203 passes around the drive sprocket 504 and the driven sprocket 202 and connects to the lifting frame 205, the lifting frame 205 rises accordingly during the movement of the lifting chain 203. The upper surface of the fork tooth 303 connected to the lifting frame 205 contacts the bottom of the copper stack, thereby driving the copper stack to rise and leaving space for the copper stack behind to pass through. At this time, the chain machine is in motion. Other... The copper stack at the workstation can be smoothly transferred to other workstations via the chain conveyor. After the copper stack has completely passed, the chain conveyor stops running, the drive motor 401 reverses, causing the lifting frame 205 to drive the fork 303 and the copper stack to descend smoothly until the copper stack falls back onto the chain conveyor. Then, the robot continues to stack copper plates on the copper stack until the set height is reached. After the copper stack is stacked, the chain conveyor at that workstation starts again to transport the finished copper stack to the next workstation, completing one work cycle. This elevator is suitable for similar light and heavy load conditions in other industries.
