Description

Technical Field

[0001] This utility model relates to the field of conveyor equipment maintenance technology, and in particular to a conveyor roller disassembly device. Background Technology

[0002] Conveyor rollers, as core components of belt conveyors, roller conveyors, and other equipment, are widely used in numerous industries such as mining, metallurgy, ports, and logistics. During long-term high-load operation, conveyor rollers require regular maintenance or replacement due to wear, corrosion, or bearing damage. Therefore, safely and efficiently removing them from the frame is an important part of equipment maintenance.

[0003] In current maintenance practices, the disassembly of conveyor rollers, especially heavy ones or those jammed due to corrosion, often relies on traditional general-purpose tools and methods. Operators typically use sledgehammers to strike, long crowbars to pry, or simple jacks to push. While these methods can accomplish the disassembly task to some extent, their inherent limitations are quite obvious.

[0004] The key issue is that when using these non-specialized tools, operators can hardly guarantee that the applied thrust will act precisely on the axis of the conveyor roller. If the external force deviates, it will generate an additional bending moment along with the axial thrust, causing the conveyor roller to tilt or jam during disassembly.

[0005] This uneven loading and resulting jamming drastically increases the actual thrust required for disassembly, making the disassembly work extremely difficult and significantly increasing the labor intensity and working time for workers. More seriously, uneven stress can directly damage the shaft ends and bearings of the conveyor rollers, and even the frame or bearing housing that fixes the conveyor rollers, causing secondary damage, increasing maintenance costs, and posing safety hazards such as tool slippage.

[0006] Therefore, this utility model proposes a conveyor roller disassembly device to overcome the shortcomings of the prior art. Utility Model Content

[0007] In view of the problems in the existing conveyor roller disassembly device, which lacks a precise alignment mechanism, resulting in uneven force, low efficiency and easy damage to the equipment during disassembly, this utility model aims to provide a conveyor roller disassembly device with an improved structure that can effectively solve the above problems.

[0008] This utility model provides a conveyor roller disassembly device, including: a support assembly and a pushing assembly; as well as a moving trolley, a connecting plate, an intermediate connecting frame and a disassembly assembly.

[0009] The mobile trolley, the connecting plate, the intermediate connecting frame, and the assembly / disassembly assembly together constitute a movable positioning and bearing mechanism, which is used to accurately position the pushing assembly axially before the pushing operation.

[0010] Furthermore, the support assembly includes an I-beam extending along the length of the device, and the moving trolley is slidably mounted on the I-beam; the connecting plate is fixedly connected to the bottom of the moving trolley by a second fixing bolt; the intermediate connecting frame is fixedly connected to the bottom of the connecting plate; the pushing assembly is detachably suspended below the intermediate connecting frame by the disassembly assembly, the disassembly assembly including a connector and a hanger rod, the connector being connected to the bottom of the intermediate connecting frame, the upper end of the hanger rod being connected to the connector, and the lower end of the hanger rod being connected to the pushing tube, forming a stable and reliable load-bearing and connecting chain from top to bottom.

[0011] Preferably, the conveyor roller disassembly device further includes a motor, which is fixedly mounted on the mobile trolley. Its output shaft cooperates with the support assembly through a gear and rack mechanism or a belt drive mechanism to realize the automated driving and precise positioning of the mobile trolley.

[0012] Preferably, the connector is fixed to the bottom of the intermediate connecting frame by at least two lead screws, which enhances the rigidity and reliability of the connection between the assembly / disassembly component and the intermediate connecting frame.

[0013] Preferably, the lower end of the boom is detachably fixed to the top of the push tube by at least two first fixing bolts. This threaded connection allows the push tube, as an actuating component, to be quickly disassembled and replaced, improving maintainability.

[0014] Preferably, the support assembly further includes a front bracket and a rear bracket, with the I-beam fixedly connected between the front bracket and the rear bracket, providing a solid and stable foundation for the entire device.

[0015] Preferably, in addition to the front bracket and the rear bracket, the support assembly further includes a first fixing plate, which is horizontally fixedly connected to the middle of the front bracket and the rear bracket to further enhance the overall structural strength of the support assembly.

[0016] Preferably, in addition to the first fixing plate, the support assembly further includes a second fixing plate, which is fixedly connected to the top of the I-beam and to the first fixing plate, together forming a more stable reinforced frame structure.

[0017] Preferably, the push tube has a hollow structure and a nitrogen circulation system installed inside, with a flow channel for circulating nitrogen so that it can be circulated and cooled during use to reduce the temperature of the push tube and prevent high-temperature deformation.

[0018] This utility model has the following beneficial effects: 1. This utility model solves the problem in the prior art that the disassembly device is difficult to accurately align with the axis of the conveyor roller, resulting in uneven force during disassembly, low efficiency and easy damage to the equipment. It achieves the technical effect of accurate positioning before disassembly and ensuring a stable, efficient and safe disassembly process.

[0019] 2. This utility model, by setting a nitrogen circulation system inside the push tube, enables the push tube to be circulated and cooled by nitrogen during use, which greatly reduces the temperature of the push tube and avoids high-temperature deformation of the push tube when it is working at high temperatures, thereby affecting the pushing accuracy and working efficiency.

[0020] 3. This utility model, by designing a special disassembly and assembly assembly consisting of a connector, a hanger, and fixing bolts, is used to connect the intermediate connecting frame and the push tube, which serves as the execution end. This solves the problem of the complicated and time-consuming replacement process of the push tube, which is a vulnerable part, after it is damaged. It achieves the technical effect of enabling quick and convenient repair or replacement of core components, significantly improving equipment maintainability and reducing downtime.

[0023] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions in the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0024] Example: Please refer to Figures 1 to 7 This utility model provides a conveyor roller disassembly device, which aims to solve the problems of the lack of a precise alignment mechanism and uneven force during disassembly due to high temperature deformation, which easily damages the equipment.

[0025] like Figures 1 to 7 As shown, the conveyor roller disassembly device includes a support assembly 3, a pushing assembly 1, and a positioning and bearing mechanism for movably mounting the pushing assembly 1 onto the support assembly 3. The support assembly 3 includes an I-beam 303 extending along the length of the device, which serves as the track foundation for the entire device. The pushing assembly 1 includes a hydraulic tank 101, a piston rod 102 driven by the hydraulic tank 101 to perform reciprocating linear motion, and a pushing tube 103 fixedly connected to the end of the piston rod 102. The positioning and bearing mechanism includes a moving trolley 4, a connecting plate 2, an intermediate connecting frame 5, and a disassembly and assembly assembly 6. Cart 4 is slidably mounted on I-beam 303. Connecting plate 2 is fixedly connected to the bottom of the moving cart 4 by second fixing bolt 8. Intermediate connecting frame 5 is fixedly connected to the bottom of connecting plate 2. Pushing component 1 is suspended below intermediate connecting frame 5 by disassembly and assembly component 6. Disassembly and assembly component 6 specifically includes connector 603 and hanger 601. Connector 603 is connected to the bottom of intermediate connecting frame 5. The upper end of hanger 601 is connected to connector 603. The lower end of hanger 601 is connected to push tube 103, thus forming a complete pushing unit that can move along the track of I-beam 303 to achieve precise alignment.

[0026] To achieve the aforementioned precise alignment, the positioning and supporting mechanism utilizes a specific structural fit and connection between the moving trolley 4, connecting plate 2, intermediate connecting frame 5, and assembly / disassembly assembly 6 to securely support the pushing assembly 1 on the supporting assembly 3, enabling it to move precisely. Please refer to [the relevant documentation / reference]. Figure 1 , Figure 2 and Figure 4 The core structure will be described in detail below: The bottom of the mobile trolley 4 is equipped with a slide rail structure that mates with the top flange of the I-beam 303, allowing the mobile trolley 4 to slide stably along the length of the I-beam 303. A connecting plate 2 is fixedly connected to the bottom of the mobile trolley 4 via a second fixing bolt 8. The connecting plate 2 increases the connection area between the mobile trolley 4 and the structure below. An intermediate connecting frame 5 is welded and fixed to the bottom of the connecting plate 2, forming a stable load-bearing platform. The pushing tube 103 in the pushing assembly 1 is suspended below the intermediate connecting frame 5 via the disassembly assembly 6. This mechanism allows the mobile trolley 4 to drive all the connecting components below. The sliding structure of the connecting parts and the pushing assembly 1 ensures the stability and positioning accuracy of the pushing tube 103 during the alignment process with the conveying roller. The pushing tube 103 is also equipped with a circulation system for nitrogen circulation, which allows the pushing tube 103 to maintain a low temperature for a long time through nitrogen circulation, avoiding deformation due to high temperature. To achieve automated movement, a motor 7 is also provided. The motor 7 is fixedly installed on the moving trolley 4, and its output shaft cooperates with the support assembly 3 through a gear and rack mechanism or a belt drive mechanism to drive the moving trolley 4 to reciprocate on the I-beam 303.

[0027] Based on the above embodiments, the present invention may further include the following preferred technical solutions: As a preferred embodiment, please refer to Figure 1 , Figure 5 , Figure 6 and Figure 7 To further enhance the structural strength and stability of the entire device, the structure of the support component 3 can be specified. The support component 3 also includes a front support 301 and a rear support 302. The two ends of the I-beam 303 are respectively fixedly connected to the front support 301 and the rear support 302. The support component 3 also includes a first fixing plate 304, which is horizontally fixedly connected to the middle of the front support 301 and the rear support 302. The support component 3 further includes a second fixing plate 305, which is fixedly connected to the top of the I-beam 303 and fixedly connected to the first fixing plate 304, together forming a reinforced and stable frame.

[0028] As another preferred embodiment, please refer to Figure 3To enable quick disassembly and replacement of the push tube 103, the connection structure of the disassembly and assembly component 6 is further defined. The connector 603 passes through the bottom of the intermediate connecting frame 5 from top to bottom through at least two screws 604 and is tightened, thereby firmly fixing the connector 603 to the bottom of the intermediate connecting frame 5. The lower end of the lifting rod 601 is detachably fixed to the top of the push tube 103 through at least two first fixing bolts 602. This threaded connection method makes the installation and separation of the push tube 103 simple and quick.

[0029] As another preferred embodiment, in order to improve the performance of the push tube 103 under huge thrust, the push tube 103 is designed as a hollow structure and has a flow channel inside for introducing nitrogen gas so that low temperature nitrogen gas can be introduced for cooling before operation.

[0030] The working principle of this utility model's conveyor roller disassembly device is as follows: When the conveyor roller needs to be disassembled, nitrogen gas can first be introduced into the hollow structure of the push tube 103. At this time, the introduced nitrogen gas forms a closed loop under the action of the circulation system in the push tube 103, which quickly removes the heat inside the tube, allowing the push tube 103 to maintain a low temperature for a long time. Then, the motor 7 is started, and the motor 7 drives the moving trolley 4 to slide along the H-beam 303 track on the support assembly 3. Since the bottom of the moving trolley 4 is connected to and supports the entire push assembly 1 in sequence through the connecting plate 2 and the intermediate connecting frame 5, the push assembly 1 will move synchronously with the moving trolley 4. By controlling the movement of the moving trolley 4, the axis of the push tube 103 can be precisely adjusted to be aligned with the axis of the conveyor roller to be disassembled, thereby solving the problem of disassembly difficulties or equipment damage caused by inaccurate positioning in the prior art.

[0031] After alignment is completed, the hydraulic tank 101 is activated. The hydraulic tank 101 generates high-pressure oil to drive the piston rod 102 to extend. The piston rod 102 drives the push tube 103 to make a smooth linear pushing motion. The push tube 103 directly acts on the end face of the conveyor roller, smoothly pushing it out of the installation position and completing the disassembly operation.

[0032] When the push tube 103, which is a vulnerable part, needs to be repaired or replaced, the operator only needs to loosen and remove the first fixing bolt 602 used to connect the boom 601 and the push tube 103 to quickly remove the push tube 103 from the disassembly and assembly assembly 6. The installation is done in reverse. The whole process is convenient and efficient.

[0033] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
