Description

Technical Field

[0001] This utility model applies to the field of steel structure product manufacturing and processing technology, and in particular relates to a large steel structure product transfer track. Background Technology

[0002] In current industrial production environments, especially during the manufacturing of large steel structure products, efficient and safe product transfer is a key technical challenge. Traditional rail systems are mainly used to support the transportation of light or medium-sized goods, and their applicability and efficiency are often limited when dealing with large steel structure products. Existing rail systems typically have the following drawbacks:

[0003] Traditional track systems lack flexibility and adaptability. The processing of large steel structure products often involves multiple steps, such as feeding, spraying, drying, and unloading, each requiring different transfer methods. However, traditional track systems are mostly of a single type, making it difficult to meet diverse process requirements. This not only increases the complexity of the production line layout but also reduces overall work efficiency.

[0004] To solve the above-mentioned technical problems, this utility model designs a large steel structure product transfer track. Utility Model Content

[0005] This utility model provides a large steel structure product transfer track, which aims to solve the problem of lack of flexibility and adaptability of traditional track systems.

[0006] A large steel structure product transfer track includes a circulating track mechanism, a transfer unit, and a workpiece handover station. The circulating track mechanism includes a product transfer section and an empty return section. The product transfer section extends along the processing direction and passes through multiple functional compartments in sequence. The transfer unit is movably mounted on the circulating track mechanism to carry and transport the steel structure product. The workpiece handover station is located at both ends of the product transfer section to transfer the steel structure product on the circulating track mechanism. The circulating track mechanism is independently set up in at least two different functional compartments.

[0007] Based on the above technical solution, the circulating track mechanism includes at least one of a suspended track mechanism, a ground track mechanism, or a combination of suspended track and ground track mechanism.

The sliding frame moves on the ground track connecting rail to realize the switching of the steel structure product between the ground track transfer track and the ground track return track. Conveying rollers are provided on the ground track transfer track, the ground track return track, and the ground track connecting rail. The support frame is placed on the conveying rollers and moves along the conveying rollers.

[0026] Example 1

[0027] like Figure 1 As shown, a large steel structure product transfer track includes a circulating track mechanism, a transfer unit, and a workpiece handover station; the circulating track mechanism includes a product transfer section and an unloaded return section.

[0028] The continuous operation of the entire system is achieved through a circulating track mechanism, particularly the design of the product transfer section and the empty return section. The product transfer section extends along the processing direction and passes through multiple functional compartments 4 in sequence, ensuring that each steel structure product 9 can complete all processes in a predetermined order and can be automatically transferred, thereby improving overall production efficiency.

[0029] The transfer unit is movably mounted on the circulating track mechanism to carry and transport the steel structure product 9; the workpiece handover station is located at both ends of the product transfer section to transfer the steel structure product 9 on the circulating track mechanism. Specifically, the workpiece handover station at the starting end is used to realize the loading of the steel structure product to be processed from the external loading process to the transfer unit.

[0030] The workpiece handover station at the end is used to unload the processed steel structure product 9 from the transfer unit to the external unloading process. In at least two different functional compartments, the circulating track mechanism is independently set up, and the circulating track mechanism includes at least one of a hanging track mechanism, a ground track mechanism, or a combination of hanging and ground tracks.

[0031] The circulating track mechanism is a suspended track mechanism, which includes a frame 11 and a ring track 12 mounted on the frame 11. The transfer unit is slidably connected to the ring track 12. Figure 2 As shown, the transfer unit consists of an electric hoist 21 and a detachable hook 22 suspended below it, with the steel structure product 9 hung on the detachable hook 22. The electric hoist 21 and the detachable hook 22 allow for easy hanging, transfer, or unloading of the steel structure product, making it suitable for handling products of different sizes and weights.

[0032] The electric hoist can be composed of a motor, reducer, drum, wire rope or chain, etc. In this invention, the electric hoist not only has vertical lifting capability, but also can move horizontally along the circular track 12. The electric hoist is a device well known to those skilled in the art, and therefore will not be described in detail here.

[0033] The overhead rail mechanism moves the steel structure product 9 via suspension, effectively utilizing the space above the factory building and reducing the floor space occupied by ground equipment. This helps optimize the workshop layout and leaves more floor space for other operations.

[0034] The functional compartment 4 has a chute 41 at its top, and the electric hoist 21 is slidably connected to the chute 41. Through the design of the chute, the electric hoist 21 can move precisely laterally within the functional compartment 4. This allows the steel structure product to be accurately positioned to the specific location requiring processing or handling. The chute 41 provides a stable guide path for the electric hoist 21, avoiding safety hazards caused by track deviation or instability.

[0035] During operation, at the starting point of the production line, the unprocessed steel structure product 9 is loaded onto the transfer unit via a workpiece handover station. Specifically, workers or automated equipment hang the steel structure product 9 on a detachable hook 22 below an electric hoist 21, such as an electric hoist.

[0036] After the steel structure product 9 is installed, the electric hoist begins to move along the circular track 12 set on the frame 11. This track is designed as a closed loop to ensure that the product can pass through each functional compartment 4 according to the predetermined path.

[0037] As the electric hoist moves along the product transfer section of the circular track, the steel structure product 9 passes through multiple functional compartments (such as the feeding compartment, spraying compartment, drying compartment, and discharging compartment). Each functional compartment has a chute 41 at the top to ensure that the electric hoist can stably enter and exit the compartment and perform corresponding processing on the steel structure product.

[0038] Once the steel structure product 9 has completed all the necessary processing steps, the electric hoist takes it to the workpiece handover station on the production line, where it is transferred to the external unloading process, ready to enter the next production stage or be directly transported.

[0039] The electric hoist will then return to its initial position along the unloaded return section, allowing it to be reused in the circular track.

[0040] Example 2

[0041] Based on the above embodiment 1, the difference between this embodiment and embodiment 1 is that the circulating track mechanism is a ground track mechanism.

[0042] like Figure 3 As shown, the ground rail mechanism includes a parallel ground rail transfer rail 16 and a ground rail return rail 17. By setting two parallel rails, one for forward transport of steel structure products 9 and the other for empty return, continuous material flow is achieved, improving the efficiency of the entire production line.

[0043] like Figure 4 and Figure 5 As shown, ground rail transfer rail 16 is provided with ground rail connecting rails 18 at both ends, and a sliding frame 181 is slidably connected to the ground rail connecting rail 18. The transfer unit is a support frame 182, and the support frame 182 is slidably connected to the sliding frame 181. The sliding frame 181 moves on the ground rail connecting rail 18 to realize the switching of the steel structure product 9 between the ground rail transfer rail 16 and the ground rail return rail 17.

[0044] Conveying rollers are installed on the ground rail transfer rail 16, ground rail return rail 17, and ground rail connecting rail 18. The support frame 182 is placed on the conveying rollers and moves along them. Each conveying roller or a group of conveying rollers is connected to one or more drive motors. These motors provide power, enabling the conveying rollers to rotate. A control system is also installed on the conveying rollers to coordinate the operation of each drive motor, ensuring that the conveying rollers can run at a predetermined speed and direction.

[0045] The sliding frame can move on the ground rail connecting rail 18, allowing the carrier frame to smoothly switch between the ground rail transfer rail 16 and the ground rail return rail 17. This design reduces waiting time and ensures efficient material handling.

[0046] The support frame 182 includes a frame structure and bottom rollers. The bottom rollers cooperate with the conveying rollers to move the support frame 182 on the ground rail transfer rail 16, the ground rail return rail 17 and the ground rail connecting rail 18.

[0047] Preferably, a transition plate or transition wheel is typically installed in the gap between the ground rail transfer rail 16 and the ground rail connecting rail 18. These devices fill the gap, allowing the bottom rollers on the support frame 182 to move smoothly from one rail to another.

[0048] During operation, unprocessed steel structure products are loaded onto the support frame 182 via an external loading process and workpiece handover station. Workers or automated equipment then place the steel structure products onto the support frame, preparing them for the next process.

[0049] After the control system is started, the drive motor drives the conveyor roller to rotate, so that the support frame 182 and the steel structure product 9 on it begin to move along the ground rail transfer rail 16.

[0050] The steel structure product 9, along with the support frame 182, passes through multiple functional compartments in sequence, undergoing various processes. The conveyor rollers within each functional compartment ensure the support frame passes smoothly and perform specific operations as needed.

[0051] When the support frame 182 reaches the end of the ground rail transfer rail 16, the steel structure product is unloaded from the support frame 182 and transferred to the external unloading process. The support frame 182 then enters the ground rail connecting rail 18. At this time, the sliding frame 181 moves along the ground rail connecting rail 18, transferring the support frame 182 from the ground rail transfer rail to the ground rail return rail 17. The support frame 182 returns to its starting position along the ground rail return rail 17, ready for the next loading task. During this process, the support frame also relies on the drive of the conveyor rollers to ensure its smooth movement.

[0052] Example 3

[0053] Based on the above embodiment 1, the difference between this embodiment and embodiment 1 is that the circulating track mechanism is a segmented composite track.

[0054] like Figures 6 to 9 As shown, to adapt to different process requirements, the circulating track mechanism is a segmented composite track, including at least one suspended track section 13 and at least one ground track section 14. An electric hoist 21 is slidably connected to the suspended track section 13, and a carrying trolley 23 is slidably connected to the ground track section 14. The functional compartment 4 includes a feeding compartment, a spraying compartment, a drying compartment, and a discharging compartment.

[0055] There are two ground track sections 14 and two carrier trolleys 23, with the carrier trolleys 23 slidably connected to the ground track sections 14. The carrier trolleys 23 are respectively mounted on the ground track-type transfer units in the feed and discharge bins. The bottom of each carrier trolley 23 is equipped with rollers designed to match the tracks on the ground track sections 14. Each carrier trolley or group of trolleys is typically connected to one or more drive motors. These motors provide power, enabling the trolleys to move along the tracks.

[0056] The feeding hopper and discharging hopper are equipped with ground rail sections 14, and the spraying hopper and drying hopper are equipped with hanging rail sections 13.

[0057] Different functional compartments may require different types of handling methods. For example, spraying and drying compartments are suitable for suspended operation using overhead rail section 13 to avoid interference from ground equipment and ensure uniform processing; while feeding and discharging compartments are more suitable for ground rail sections because they typically need to support greater weight. The segmented composite rail design allows for flexible selection of appropriate handling methods according to specific needs.

[0058] Segmented composite tracks allow steel structure products to switch between suspended and ground rail sections according to actual needs, reducing unnecessary handling steps and time, and improving the overall logistics efficiency of the system.

[0059] In use, the unprocessed steel structure product 9 is loaded from the workpiece handover station onto the carrying trolley 23 via an external loading process. Workers or automated equipment then place the steel structure product onto the carrying trolley, preparing it for the next process.

[0060] The ground track section 14 is equipped with a control system, a drive motor and a conveyor roller. After starting, the drive motor drives the conveyor roller to rotate, so that the trolley 23 and the steel structure product 9 on it begin to move along the ground track section 14.

[0061] In front of certain functional compartments 4 (such as spraying compartments and drying compartments), there are transition devices (such as lifting platforms or transfer robotic arms) to transfer steel structure products 9 from ground rail section 14 to hanging rail section 13.

[0062] The steel structure product 9 is transferred from the carrying trolley 23 to the detachable hook 22 of the electric hoist 21 via a transition device. The steel structure product 9 is suspended on the electric hoist 21 and moves along the hanging rail section 13, passing through functional compartments such as the spraying compartment and the drying compartment in sequence.

[0063] At this point, the carrying trolley 23, located on the ground rail section of the feeding hopper, returns to its initial position and continues to accept the next steel structure product 9.

[0064] After completing all necessary procedures, the steel structure product 9 returns to the ground rail section of the discharge hopper. At this point, it is transferred from the overhead rail section 13 to the carrying trolley 23 via a transition device, and then proceeds along the ground rail section to the end workpiece handover station.

[0065] It should be noted that the electric hoist, the carrying trolley, etc. in this embodiment are all general standard parts or components known to those skilled in the art. Their structure and principle can be learned by those skilled in the art through technical manuals or conventional experimental methods.

[0066] The present invention has been described above by way of example, but the present invention is not limited to the specific embodiments described above. Any modifications or variations made based on the present invention shall fall within the scope of protection claimed by the present invention.
