Abstract
Description
Technical Field
[0001] This utility model relates to the field of bucket elevator technology, specifically a protective structure for the head wheel of a bucket elevator. Background Technology
[0002] During the operation of a bucket elevator, the head wheel is the core transmission component, and its stable operation directly affects the conveying efficiency and safety of the equipment. In order to prevent the head wheel and rotating components such as chains and buckets from malfunctioning or causing safety accidents due to external interference (such as accidental contact by personnel or intrusion of foreign objects), the industry generally adopts protective structures to protect the head wheel. These structures are mostly closed fixed covers, which are fixed to the outside of the head wheel by rigid connections such as bolts, forming a physical isolation barrier.
[0003] However, traditional covers are usually designed as an integral structure to ensure protective sealing. Since the meshing area between the head wheel and the chain is prone to wear or jamming due to material residue and dust accumulation, the cover needs to be opened regularly for inspection, cleaning and lubrication of components. The disassembly and assembly of traditional structures are inconvenient, which increases the labor intensity of maintenance work and prolongs downtime. Especially in continuous production, frequent maintenance operations will seriously affect the continuity of production.
[0004] To address this, a protective structure for the head wheel of a bucket elevator is proposed. Utility Model Content
[0005] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a protective structure for the head wheel of a bucket elevator to solve the problems mentioned in the background art.
[0006] To solve the above-mentioned technical problems, this utility model provides the following technical solution.
[0007] This utility model provides a protective structure for the head wheel of a bucket elevator, including a first cover and a second cover, which are spliced together. The side walls of the first cover and the second cover are provided with shaft holes. Fixing mechanisms are provided between the top of the first cover and the top of the second cover, and between the bottom of the first cover and the bottom of the second cover.
[0008] The fixing mechanism includes fixing rings fixedly disposed on the side walls of the first cover and the second cover, and fixing bolts and fixing nuts that cooperate with each other are provided between two adjacent fixing rings.
[0009] Preferably, the first cover and the second cover are respectively provided with a sealing slot and a sealing strip on opposite sides, and the first cover and the second cover are sealed together by the insertion and cooperation of the sealing slot and the sealing strip.
[0010] Preferably, both the side walls of the first cover and the side walls of the second cover are provided with transparent observation windows.
[0011] Preferably, both the end opening of the first cover and the end opening of the second cover are fixedly provided with sealing plates, and the two sealing plates are arranged in contact.
[0012] Preferably, two fixing rods are symmetrically fixed to the side walls of the first cover and the second cover, and fixing holes are provided at the ends of the fixing rods.
[0013] Preferably, the interior of the shaft hole is used to accommodate the rotating shaft of the head wheel, and a bearing is provided between the shaft hole and the rotating shaft.
[0014] Preferably, both the first cover and the second cover are made of die-cast aluminum alloy.
[0015] Compared with the prior art, the present invention has the following beneficial effects:
[0016] By designing the protective structure as a spliced structure of the first and second covers, and using a fixing mechanism (fixing ring, fixing bolt, fixing nut) to achieve quick assembly and disassembly, the problem of cumbersome assembly and disassembly of the traditional integral cover is solved. During maintenance, only the fixing bolt and fixing nut need to be removed to separate the first and second covers, directly exposing the head wheel and chain meshing area. This greatly simplifies the assembly and disassembly process, reduces maintenance labor intensity, shortens downtime, and ensures the continuity of continuous production. Attached Figure Description

[0022] A bucket elevator head wheel protection structure, such as Figure 1-4As shown, the device includes a first cover 1 and a second cover 2, which are spliced together. Both the first cover 1 and the second cover 2 are made of die-cast aluminum alloy. Aluminum alloy has high structural strength, good protection, is lightweight, and has a long service life. The side walls of both the first cover 1 and the second cover 2 have shaft holes 3. The rotating shaft of the head wheel passes through the shaft holes 3, and a bearing is provided between the shaft holes 3 and the rotating shaft to ensure the stability of the rotating shaft. The first cover 1 and the second cover 2 can cover and protect the head wheel. The top of the first cover 1 and the second cover 2... Fixing mechanisms are provided between the top and bottom of the first cover 1 and the second cover 2. The fixing mechanisms include fixing rings 4 fixedly installed on the side walls of the first cover 1 and the second cover 2. Fixing bolts 5 and fixing nuts 6 are provided between two adjacent fixing rings 4. The fixing bolts 5 and fixing nuts 6 can fix the first cover 1 and the second cover 2 into a whole, so that the head wheel is better protected. There is a gap between the inner walls of the first cover 1 and the second cover 2 and the head wheel to avoid contact and friction between the inner walls of the chain and the first cover 1 and the second cover 2.
[0023] The first cover 1 and the second cover 2 are respectively provided with a sealing slot 7 and a sealing strip 8 on their opposite sides. The first cover 1 and the second cover 2 are sealed together by the insertion and cooperation of the sealing slot 7 and the sealing strip 8. While ensuring convenient disassembly and assembly, the sealing performance of the first cover 1 and the second cover 2 is enhanced, effectively preventing the intrusion of foreign objects and maintaining the protective performance.
[0024] The side walls of the first enclosure 1 and the second enclosure 2 are both equipped with transparent observation windows 9. The operating status of the internal head wheel can be directly observed through the transparent observation windows 9, and a preliminary inspection can be completed without disassembly, further improving maintenance efficiency.
[0025] A sealing plate 10 is fixedly provided at the end opening of the first cover 1 and the end opening of the second cover 2. The two sealing plates 10 are arranged in contact, and the sealing plates 10 can block the end openings of the first cover 1 and the second cover 2 as much as possible, leaving only enough space for the chain to pass through.
[0026] The side walls of the first cover 1 and the second cover 2 are symmetrically fixed with two fixing rods 11, and the ends of the fixing rods 11 are provided with fixing holes 12, which can securely install the first cover 1 and the second cover 2 after splicing and fixing on the hoist frame.
[0027] In summary: The first cover 1 and the second cover 2 are spliced together by the insertion and cooperation of the sealing slot 7 and the sealing strip 8, forming a closed protective space for the head wheel. The rotating shaft of the head wheel passes through the shaft hole 3 and is connected by a bearing, ensuring the normal operation of the head wheel while avoiding friction between the shaft and the cover. After splicing, it is fixed by a fixing mechanism, that is, by locking the adjacent fixing ring 4 with the fixing bolt 5 and the fixing nut 6, ensuring that the first cover 1 and the second cover 2 are firmly connected. The end sealing plate 10 further closes the opening and enhances the protection. The fixing rod 11 and the fixing hole 12 are used to fix the overall structure to the hoist frame to prevent displacement. The transparent observation window 9 allows direct observation of the internal head wheel and chain operation status, and preliminary inspection can be completed without disassembly. When maintenance is required, the fixing bolt 5 and the fixing nut 6 are removed to separate the first cover 1 and the second cover 2, thereby exposing the head wheel and surrounding components for operation.
[0028] 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.
