[0002] At present, belt conveyors are widely used in coal mines and power plants, and the replacement of belt conveyor drums has become one of the main maintenance contents of belt conveyors. In most belt conveyor drum replacement operations, especially the replacement of large drive drums, the belt breaking method or the combined lifting method of multiple sets of manual hoists are adopted. The above two replacement methods not only destroy the belt surface of the belt, but also have many lifting links and greater safety risks. The use of a rail platform trolley for replacing the belt drum completely eliminates the trouble of replacing large belt drums, especially drive drums, and saves the trouble of breaking the belt. At the same time, it reduces the links of a large number of manual hoisting operations. The dismantling and installation processes can be completed using the platform trolley, which shortens the maintenance time, reduces the input of maintenance personnel, and improves safety factors.

[0035] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0036] It should be noted that the terms used herein are only for describing specific embodiments and are not intended to limit the exemplary embodiments according to the present application. As used herein, unless the context clearly indicates otherwise, the singular form is also intended to include the plural form. In addition, it should be understood that when the terms "comprise" and / or "include" are used in this specification, it indicates the presence of features, steps, operations, devices, components and / or combinations thereof.

[0037] It should be noted that the terms "first", "second", etc. in the specification and claims of the present application and the above-mentioned drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence. It should be understood that the terms used in this way can be interchangeable where appropriate, so that the embodiments of the present application described herein can be implemented in an order other than those illustrated or described herein, for example. In addition, the terms "including" and "having" and any of their variations are intended to cover non-exclusive inclusions, for example, a process, method, system, product or device that includes a series of steps or units is not necessarily limited to those steps or units that are clearly listed, but may include other steps or units that are not clearly listed or inherent to these processes, methods, products or devices.

[0038] Now, exemplary embodiments according to the present application will be described in more detail with reference to the accompanying drawings. However, these exemplary embodiments may be implemented in a variety of different forms and should not be construed as being limited to the embodiments described herein. It should be understood that these embodiments are provided to make the disclosure of the present application thorough and complete, and to fully convey the concepts of these exemplary embodiments to those of ordinary skill in the art. In the accompanying drawings, for the sake of clarity, the thickness of the layers and regions may be enlarged, and the same reference numerals are used to represent the same devices, and thus their descriptions will be omitted.

[0039] It should be noted that, currently, the methods for replacing the drive roller are generally hoisting and slide box type. There are great risks during hoisting, and most of them require belt breaking. The other is the slide type, in which the roller is moved horizontally to the inside of the belt through the slide, and the replacement process will damage the rubber coating on the surface of the drive roller. Among them, the hoisting type is only suitable for small rollers. Large rollers are not safe, and the belt needs to be broken, which damages the original belt surface. The slide type is not suitable for replacing large rollers. During the replacement of the roller, the roller is easy to slip and injure people. The sliding process requires the use of a manual hoist for axial traction, and the rubber coating on the surface of the roller is easy to be damaged during the sliding process.

[0040] A replacement device for replacing the belt conveyor roller is located at one side of the belt conveyor to be operated, and an extension direction of the replacement device is arranged toward the axial direction of the belt conveyor to be operated.

[0041] Combination Figure 1 to Figure 2 As shown, according to a specific embodiment of the present invention, a replacement device for replacing a belt conveyor roller is provided.

[0042] like Figure 1 , Figure 2 As shown, the replacement device for replacing the roller of the belt conveyor includes: a rail portion 10; a sliding portion 20, which is slidably arranged on the rail portion 10; a supporting portion 30, which is arranged on the sliding portion 20, and the supporting portion 30 is connected to the sliding portion 20, and the supporting portion 30 has a limiting portion for accommodating the roller 100 to be replaced; the operating sliding portion 20 is movably arranged along the length direction of the rail portion 10, and can drive the roller 100 to be replaced on the support portion 30 to move to the inside of the belt to be operated.

[0043] In this embodiment, the roller 100 to be replaced can be quickly moved to the interior of the belt conveyor through the smooth movement of the sliding part 20 on the track part 10, avoiding the complicated process of breaking the belt or a large number of manual hoists combined for lifting in the traditional replacement method, greatly saving the time required for replacement. Since the replacement device can be translated along the track, there is no need to break the belt to remove or install the roller, which can avoid damage to the tape surface and maintain the integrity of the tape and transportation efficiency.

[0044] Furthermore, the replacement device for replacing the roller of the belt conveyor also includes: a hoisting part, which is arranged above the support part 30, and is used to hoist the roller 100 to be replaced onto the support part 30. The hoisting part can lift the roller to be replaced and accurately place it on the limiting part of the support part, ensuring accurate alignment between the roller and the support part, and avoiding damage to the belt or roller due to position deviation during the replacement process. Through the mechanized operation of the hoisting part, the need for manual direct handling and alignment of the roller is reduced, especially in the replacement of large rollers, which greatly reduces the manpower burden and reduces the errors and safety risks caused by manual operation.

[0045] Furthermore, the sliding portion 20 includes: a roller assembly 21 , which is slidably connected to the track portion 10 ; and a connecting assembly 22 , one end of which is connected to the roller assembly 21 , and the other end of which is connected to the support portion 30 .

[0046] The sliding connection between the roller assembly 21 and the track portion 10 ensures the smooth movement of the sliding portion 20 on the track, thereby realizing the smooth transportation of the roller 100 to be replaced, reducing the vibration and impact that may be generated during the movement, and protecting the roller and other parts of the belt conveyor. The connecting assembly 22 firmly connects the roller assembly 21 to the support portion 30 to form a stable structure that can withstand the weight of the roller to be replaced and ensure the structural stability and safety during the roller replacement process. The roller assembly 21 contacts the track portion 10 through the roller, which reduces direct friction and wear, extends the service life of the replacement device, and reduces maintenance costs.

[0047] Furthermore, the track portion 10 includes: at least two work steels 11, the at least two work steels 11 are arranged opposite to each other, and the at least two work steels 11 are extended along the axial direction of the belt conveyor to be operated.

[0048] The relative arrangement of the steel 11 provides stable support and guidance for the sliding part 20, ensuring the stability and linearity of the sliding part during movement, reducing the risk of deviation, and facilitating the precise positioning of the roller. The steel material has good load-bearing capacity and can bear the weight of the sliding part and the roller to be replaced. At the same time, the durability of the steel ensures the long-term stable use of the track part, reducing the maintenance frequency and cost.

[0049] Furthermore, the roller assembly 21 includes a front wheel assembly, which includes: two first rollers 211 , the two first rollers 211 are respectively arranged on each of the work steels 11 , and a first connecting shaft 212 , the first connecting shaft 212 is connected to at least two first rollers 211 .

[0050] The two first rollers 211 are respectively arranged on each work steel 11, providing support and balance on both sides, ensuring the stability of the sliding part 20 when moving, and reducing the deviation or overturning that may be caused by uneven force on one side. The rolling friction between the roller and the work steel 11 is much smaller than the sliding friction. Such a design greatly reduces the friction resistance between the components, reduces wear, and prolongs the service life of the roller assembly and the entire replacement device.

[0051] Furthermore, the roller assembly 21 includes a rear wheel assembly, which includes: two second rollers 213, two first rollers 211 are respectively arranged on each of the steel bars 11, and the second rollers 213 are arranged at a distance from the first rollers 211; a second connecting shaft 214, and the first connecting shaft 214 is connected to at least two second rollers 213.

[0052] Similar to the front wheel assembly, the two second rollers 213 of the rear wheel assembly are also respectively arranged on the two steel bars 11, forming a stable support structure of the front and rear double rollers, ensuring the balance of the sliding part 20 during the movement, and avoiding the instability and deviation that may be caused by the single-sided roller support. A certain distance is maintained between the first roller 211 and the second roller 213. Such a design can enhance the structural stability of the sliding part 20, especially in the case of heavy loads or long platforms, and increase the torsion resistance of the sliding part. With the support of the rear wheel assembly, the sliding part 20 can achieve smoother movement, improve the positioning accuracy when replacing the roller, and ensure that the roller can be moved to the designated position accurately. The rear wheel assembly and the front wheel assembly work together to further improve the load-bearing capacity of the sliding part, so that the replacement device can safely carry larger and heavier belt conveyor rollers, and improve the practicality and operating range of the device.

[0053] Furthermore, the connection assembly 22 includes at least four rib plates 221 , a rib plate 221 is connected between each first roller 211 and the work steel 11 , and a rib plate 221 is connected between each second roller 213 and the work steel 11 .

[0054] The rib plate 221 enhances the connection strength between the roller and the steel, ensures a stable connection between the roller assembly 21 and the track portion 10, and maintains the stability of the structure even when carrying a heavy-loaded roller. The rib plate 221 forms an additional support point between the roller and the steel, increases the overall rigidity of the sliding portion, and avoids structural distortion or deformation caused by external forces during movement.

[0055] Furthermore, the supporting portion 30 includes: a supporting plate 31 , which is disposed on the sliding portion 20 and is arc-shaped.

[0056] Since the belt conveyor drum is usually cylindrical, the design of the arc-shaped support plate 31 can better fit the outer surface of the drum, provide more stable support, and avoid rolling or instability of the drum during transportation. The arc-shaped support plate 31 can evenly distribute the weight of the drum on the entire arc surface where it contacts the support plate, reducing the problem of excessive local force, reducing the wear of the support plate and the drum, and increasing the service life of the components. Since the arc-shaped support plate 31 has a large contact area with the drum and a high degree of fit, this reduces the direct friction between the drum and the support plate, avoids damage to the drum surface (especially the rubber-coated part), and protects the performance of the drum.

[0057] Further, at least two supporting plates 31 are provided, one of the at least two supporting plates 31 is provided at one end of the sliding portion 20 , and the other of the at least two supporting plates 31 is provided at the other end of the sliding portion 20 .

[0058] The two support plates 31 can share the weight of the roller more evenly, avoiding deformation or damage that may be caused by a single support plate bearing the entire weight, and ensuring the reliability and safety of the replacement device in terms of carrying capacity. The support plates 31 at both ends provide more stable support when the roller is placed or moved, reducing the shaking or deviation of the roller during the replacement process, enhancing the stability of the overall structure, and reducing safety risks during operation.

[0059] Furthermore, a channel steel 311 is provided on one side of the support plate 31 facing the sliding part 20. The connection between the channel steel 311 and the sliding part 20 provides additional structural support, enhances the connection strength between the support plate 31 and the sliding part 20, and ensures the stability of the support plate and the sliding part when carrying a heavy-loaded roller. The channel steel 311 can optimize the force transmission path, so that the load on the support plate 31 is more effectively transmitted to the structure of the sliding part 20 through the channel steel, reducing energy loss and improving mechanical efficiency.

[0060] Furthermore, a reinforcing rib 40 is provided between one of the support plates 31 and the first connecting shaft 212 , and a reinforcing rib 40 is provided between the other support plate 31 and the second connecting shaft 214 , so as to improve the reliability and stability of the support plate 31 .

[0061] In another embodiment of the present application, the technical solution of the present application can utilize waste mine car wheels welded with angle irons, and the arc stretcher is connected to the walking track for transporting rollers. The bottom is welded with channel steel to form a platform at the same height as the driving roller, and connected to the frame. The arc trolley is placed on the platform. During the replacement of large rollers (mainly driving rollers), the tape cannot be removed, or the remaining tape is small. The roller can be hoisted onto the stretcher trolley and transported to the inside of the tape parallel to the roller axis. The replacement process will not damage the rubber coating of the new roller and the surface of the tape, and the safety level is high and the replacement speed is fast.

[0062] From the above description, it can be seen that the above embodiments of the present invention achieve the following technical effects:

[0063] (1) Safe and efficient roller replacement: The roller 100 to be replaced can be quickly and safely transported to the inside of the belt conveyor by the movement of the sliding part 20 along the track part 10, avoiding the belt breaking operation and multiple sets of manual hoist lifting that may be involved in the traditional replacement method, significantly reducing the operation risk and improving the replacement efficiency.

[0064] (2) Adjustable support stability: The support part 30 is designed with an arc-shaped support plate 31, which can adapt to the cylindrical structure of the drum and provide stable support. The setting of multiple support plates 31 and the use of channel steel 311 further enhance the bearing capacity and stability of the support plate, ensuring the safety of the drum during movement.

[0065] (3) Optimizing load distribution: The first roller 211 and the second roller 213 in the roller assembly 21, and the rib plate 221 in the connecting assembly 22, act together on the track portion 10, ensuring balanced load distribution when the sliding portion 20 moves, reducing component wear, and improving the durability and reliability of the overall structure.

[0066] (4) Modularity and adaptability: The component design of the replacement device has a high degree of modularity, such as the roller assembly, connection assembly and support part, which allows the device to be adjusted according to different belt conveyors and roller specifications, enhancing its adaptability in different working environments.

[0067] (5) Simplified operation and maintenance: The overall structural design simplifies the hoisting and moving process of the drum, reduces dependence on manpower, and also facilitates maintenance and inspection by operators, reducing maintenance time.

[0068] (6) Reduce damage to the tape and the roller: During the replacement process, the roller and the tape remain connected to avoid damage to the tape due to broken tape. At the same time, the design of the arc-shaped support plate 31 reduces the wear on the rubber coating of the roller, protecting the integrity and performance of the equipment.

[0069] (7) Simplified structure and cost control: Compared with the traditional replacement method, the structure of this device is simpler, which reduces unnecessary equipment use and reduces overall costs.

[0070] (8) Improved operational flexibility: The track portion 10 of the device is designed to be composed of at least two relatively disposed work steels 11, which can be arranged according to site conditions, thereby increasing operational flexibility and applicability.
