Description

Technical Field

[0001] This utility model relates to the field of chain bucket machine maintenance technology, specifically to a chain conveying device for a chain bucket slag conveyor. Background Technology

[0002] A chain bucket conveyor, also known as a chain bucket machine, is an industrial device used for conveying powdery, granular, and small lump materials. It achieves horizontal or inclined conveying through buckets running along a track, and features flexible layout and strong conveying capacity. In the continuous conveying of boiler ash and slag, the conveying conditions are harsh; the chain track of the chain bucket conveyor has a limited lifespan, requiring disassembly of the chain during maintenance; and the movable connection between each chain link results in a lack of support during chain transfer. The chain bucket conveyor used in our plant has 200 sets of chain buckets with guide wheels. Due to the limited working area at the tail end, it cannot be transported by overhead crane. Manual handling involves disassembling the chain into sections of 5 sets for transport. Even with segmentation, each 5 sets weigh approximately 200 kg, making the transfer time-consuming, labor-intensive, and prone to damaging the plant floor. Utility Model Content: To address the shortcomings of existing technologies, this utility model provides a chain conveying device for a chain bucket slag conveyor. This device allows for segmented transport of the chain and includes multiple lifting points, avoiding transfer problems caused by the movable connection of various chain nodes. Furthermore, it eliminates the need for manual handling, thus improving transfer efficiency.

[0011] Figure 2 This is a schematic diagram of the installation state before hoisting of this utility model.

[0012] Figure 3 This is a schematic diagram of the connection relationship of this utility model.

[0013] Figure 4 This is a partial disassembly diagram of the present invention.

[0014] In the diagram, the components are: horizontal frame 1, first movable rod 2, support rod 3, connector 4, guide wheel 4.1, mounting plate 4.2, side frame 5, movable groove 5.1, adjustment hole 5.2, second movable rod 6, traveling wheel 7, lifting rope 8, hook 8.1, adjusting frame 9, positioning rod 10, adjusting disc 11, lifting ring 12, and chain 13. Detailed implementation method: like Figure 1-4 As shown, a chain conveying device for a bucket elevator is disclosed. This device is used to transport the chain 13 out of a narrow working face. The device is moved via a side frame 5, on which a connecting member 4 is slidably mounted. A cross frame 1 is fixed above the center of the side frame 5. The cross frame 1 is connected to the side frame 5 via a support rod 3. The top of the support rod 3 is fixedly connected to the cross frame 1, and the bottom of the support rod 3 is rotatably connected to the connecting member 4. This allows the cross frame 1 to be pried back and forth around the rotatable connection position. The connecting member 4 includes a guide wheel 4.1 and a mounting plate 4.2. The guide wheel 4.1 is movably mounted on the mounting plate 4.2. Guide rails are provided on the upper and lower sides of the side frame 5. The guide wheel 4.1 is clamped on the upper and lower sides of the side frame 5 and moves along the guide rails. Furthermore, to control the second movable rod 6, the mounting plate 4.2 of the connecting member 4 is fixedly connected to the second movable rod 6, and a movable groove 5.1 is provided on the side frame 5 at the corresponding connection position. The mounting plate 4.2 moves synchronously with the second movable rod 6. One or more adjustment holes 5.2 are provided on the outer side of the side frame 5; an adjustment frame 9 is fixed on the outer side of the mounting plate 4.2; the side frame 5 passes through the inner side of the adjustment frame 9; a threaded hole is provided in the middle of the adjustment frame 9, and a positioning rod 10 is screwed into the hole; the positioning rod 10 is adjusted and pressed to fix the second movable rod 6 by rotation.

[0015] like Figure 1-4 As shown, a first movable rod 2 is movably inserted into the inner side of the cross frame 1; a threaded hole is provided on the end surface of the cross frame 1, and an adjusting disc 11 is screwed into the hole. The bottom of the screw of the adjusting disc 11 presses and fixes the first movable rod 2. A second movable rod 6 is movably inserted into the inner side of the side frame 5; a lifting rope 8 is attached to the first movable rod 2 and the body of the cross frame 1, and the two ends of the lifting rope 8 are respectively connected to the chain 13 of the bucket chain conveyor; the bottom of the side frame 5 and the second movable rod 6 are provided with traveling wheels 7. In order to prevent the lifting rope 8 from rolling on the cross frame 1 and the first movable rod 2, a lifting ring 12 is fixed to the surface of the cross frame 1 and the first movable rod 2; the lifting rope 8 passes through the lifting ring 12, the lifting ring 12 restricts the position of the lifting rope 8, and the two ends of the lifting rope 8 are respectively fixed with hooks 8.1; the hooks 8.1 are provided with grooves for insertion and engagement with the chain 13. This ensures the stability of the lifting. Unless otherwise described, the fixing methods mentioned above are all welded or threaded fastened using common technical means in the industry.

[0016] Workflow When the operator controls the handle of the crossbeam 1, causing the first end of the crossbeam 1 to move upward, a certain distance will inevitably be created between the end of the crossbeam 1 and the end of the first movable frame, resulting in downward pressure. After downward pressure, the end of the lifting rope 8, which overlaps the end of the crossbeam 1 and the end of the first movable rod 2, can approach the chain 13 using the downward pressure distance, facilitating the fixing of the hook 8.1. The length of the lifting rope 8 is less than the distance from the crossbeam 1 to the ground. When the first end of the crossbeam 1 is pressed down, the end of the crossbeam 1 and the end of the first movable rod 2 tilt upward, causing the corresponding end of the lifting rope 8 to drive the chain 13 upward, causing that part of the chain 13 to detach from the ground. After the lifting rope 8 and chain 13 at the first end of the crossbeam 1 are fixed by the hook 8.1 and then reset, the crossbeam 1 is placed in a horizontal position, and the corresponding part of the chain 13 at the first end of the crossbeam 1 can also detach from the ground. After returning to a horizontal state, the disassembled chain segment is completely detached from the ground and can then be pushed and moved.

[0017] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
