[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] The purpose of this utility model is to provide a tooling for disassembling, assembling, and repairing the main roller conveyor of a magnetic flux leakage flaw detector, so as to solve the problems existing in the prior art. It has a simple structure, is easy to use, effectively improves the work efficiency of equipment maintenance, and effectively ensures the stability of the main roller conveyor operation and the detection accuracy.

[0021] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0022] This utility model provides a tooling system for disassembling, assembling, and repairing the main roller conveyor of a magnetic flux leakage flaw detector, such as... Figure 1 As shown, the device includes: a frame body, a V-shaped positioning mechanism 3, a lifting mechanism 2, and a U-shaped pulling mechanism 1. The V-shaped positioning mechanism 3 is mounted on the frame body to support and position the roller conveyor assembly during disassembly and assembly. The lifting mechanism 2 is installed above the frame body. The U-shaped pulling mechanism 1 is movably mounted on the frame body. The U-shaped pulling mechanism 1 cooperates with the lifting mechanism 2 to apply a pulling force to the components on the roller conveyor shaft. This invention provides a complete and efficient operating platform for the disassembly, assembly, and maintenance of the main roller conveyor of a magnetic flux leakage flaw detector. The frame body serves as the supporting foundation for the entire machine, ensuring structural stability. The V-shaped positioning mechanism can accurately position the roller conveyor assembly, ensuring the roller conveyor is in the correct position during disassembly and assembly, which helps improve the accuracy of subsequent operations. The lifting mechanism 2 is installed above the frame body, providing necessary power support for hoisting components. The U-shaped pulling mechanism, in cooperation with the lifting mechanism 2, makes it feasible to remove components from the roller conveyor shaft, greatly improving the efficiency of disassembly and assembly work and reducing the difficulty of manual operation.

[0023] In a preferred embodiment, the V-shaped positioning mechanism 3 includes at least one V-shaped positioning plate, with a baffle 4 at at least one end. The V-shaped positioning plate and the baffle 4 together form a positioning space for accommodating the roller conveyor assembly. The positioning space formed by the V-shaped positioning plate and the baffle 4 can well adapt to the shape of the roller conveyor assembly and provide stable support. The V-shaped positioning plate can provide good support and positioning for the roller conveyor assembly, preventing it from swaying left and right during disassembly and assembly. The baffle 4 can prevent the roller conveyor assembly from shifting in the front-back direction, ensuring that the roller conveyor assembly is always in a precise position, further improving the accuracy and stability of the disassembly and assembly operation, which is conducive to improving work efficiency and reducing the risk of damage caused by positional deviation.

[0024] In a preferred embodiment, the baffle 4 has a U-shaped structure. Compared to a baffle 4 of ordinary shape, the U-shaped baffle 4 provides more comprehensive enclosure and protection for the roller conveyor assembly. The two sides of the U-shape can better restrict the horizontal displacement of the roller conveyor assembly, while the bottom further enhances the support stability of the roller conveyor assembly. This complete enclosure structure can effectively prevent the roller conveyor assembly from accidentally shifting or falling under special circumstances (such as swaying during lifting or movement under pulling force), thus improving the safety and reliability of operation.

[0025] In a preferred embodiment, the main frame is welded from one or more of channel steel 9, I-beams 10, and steel plates. This combination of materials leverages the advantages of different components. Channel steel 9 and I-beams 10 possess high strength and stability, capable of withstanding significant weight and external forces, ensuring the entire tooling fixture does not deform during operation. The addition of steel plates further reinforces the overall structural integrity while providing suitable surface flatness, facilitating the installation of other components. This material combination ensures both sufficient load-bearing capacity and good rigidity, adapting to various working environments and operational requirements.

[0026] In a preferred embodiment, the channel steel 9 is a #10 channel steel 9, the I-beam 10 is a #16 I-beam 10, and the steel plate thickness is 20mm. The selection of specific specifications for the #10 channel steel 9, the #16 I-beam 10, and the 20mm thick steel plate is the result of careful consideration. These material specifications achieve a balance between weight and cost while ensuring the strength and stability of the main frame structure. The specifications of the #10 channel steel 9 and the #16 I-beam 10 provide sufficient mechanical properties without making the main frame structure too bulky, facilitating installation and handling; the 20mm thick steel plate has an appropriate thickness, ensuring the strength of the welded structure without excessively increasing costs and processing difficulty due to excessive thickness, thus optimizing the tooling and equipment in terms of performance, cost, and operability.

[0027] In a preferred embodiment, limit pins 8 are provided at both ends of the I-beam 10.

[0028] In a preferred embodiment, the lifting mechanism 2 is an electric hoist, which offers numerous advantages. Electric hoists are easy to operate, allowing for simple control of lifting and lowering movements via buttons or remote control, improving operator convenience and operational precision. They possess stable lifting capacity and can precisely adjust lifting speed and height according to actual needs, ensuring safe and stable hoisting. Compared to traditional lifting methods, electric hoists offer a high degree of automation, effectively reducing the intensity and risk of manual operation, and further improving the efficiency and safety of assembly and disassembly work.

[0029] In a preferred embodiment, the U-shaped pulling mechanism 1 is made of a 20mm thick steel plate. The 20mm thick steel plate provides high strength and toughness. Sufficient thickness ensures that the U-shaped pulling mechanism will not deform or be damaged when subjected to the pulling force provided by the lifting mechanism 2 and the pulling force applied to the components on the roller conveyor shaft, ensuring smooth pulling operations. Simultaneously, this thickness of steel plate ensures the rigidity of the U-shaped pulling mechanism, allowing it to maintain a stable shape during the pulling process, better adapting to the components on the roller conveyor shaft, thereby applying the pulling force more effectively and improving the reliability and success rate of component removal.

[0030] The following are the usage methods for the tooling and equipment used for disassembling, assembling, and overhauling the main roller conveyor of the magnetic flux leakage flaw detector:

[0031] Disassembly of main machine roller conveyor components

[0032] Preparation: Move the tooling and equipment to the maintenance position of the main roller conveyor of the magnetic flux leakage flaw detector, ensuring that the main frame is placed stably and securely. Check whether the electric hoist (lifting mechanism 2), U-shaped pulling mechanism, and other components are operating normally.

[0033] Positioning roller conveyor assembly: The main roller conveyor is lifted by an electric hoist and slowly placed into the positioning space formed by the V-shaped positioning plate and the baffle 4. The V-shaped positioning plate will automatically perform initial positioning of the roller conveyor assembly, and the U-shaped baffle 4 will limit the roller conveyor assembly from all directions to ensure that the roller conveyor assembly is in an accurate and stable position.

[0034] Removing components from the shaft: Move the U-shaped pulling mechanism to a suitable position so that it is compatible with the components (such as the three-in-one reducer 5, bearings, etc.) to be removed from the roller conveyor shaft. Start the electric hoist. The electric hoist, through its lifting action, works in conjunction with the U-shaped pulling mechanism to apply a pulling force to the components on the roller conveyor shaft, thereby pulling out and removing these components one by one.

[0035] Removing roller shell 6 (if only roller shell 6 needs to be replaced): If only the worn roller shell 6 needs to be replaced, use an electric hoist to gently lift the reducer and shaft, keeping them stable. At the same time, use the jacking force to separate the shaft from the roller shell 6, thus completing the removal of roller shell 6.

[0036] Assemble main machine roller conveyor components

[0037] Installing the roller conveyor shaft: First, place the roller shell 6 within the V-shaped positioning frame. Then, using jacks, assemble the roller shaft 7 from either end of the roller shell 6. During assembly, jacks can be used to apply pressure to the roller shell 6 from left to right to precisely control the actual installation position of the roller shell 6 and the shaft, ensuring assembly accuracy.

[0038] Install other components on the shaft: When installing other components on the shaft, use one jack as support at one end of the shaft and another jack at the other end of the shaft to complete the pressing assembly work. Through the coordinated operation of the two jacks, while pressing and observing, prevent the roller shell 6 and roller shaft 7 from shifting during the assembly process, so as to successfully complete the assembly of other components on the shaft.

[0039] Throughout the entire disassembly and assembly process, the main frame, made of 10# channel steel, 16# I-beams, and 20mm thick steel plates, stably supports each component and withstands various forces during operation. The V-shaped positioning mechanism ensures that the roller conveyor assembly is in the correct position in each operation stage. The electric hoist of the lifting mechanism 2 provides stable lifting capacity, and the U-shaped pulling mechanism, in cooperation with the lifting mechanism 2, effectively completes the pulling of parts. Thus, the main roller conveyor of the magnetic flux leakage flaw detector can accurately, smoothly, quickly, and safely complete the disassembly and installation work during the disassembly and assembly maintenance process.

[0040] This utility model uses specific examples to illustrate its principles and implementation methods. The above description of the embodiments is only for the purpose of helping to understand the method and core idea of ​​this utility model. At the same time, for those skilled in the art, there will be changes in the specific implementation methods and application scope based on the idea of ​​this utility model. In summary, the content of this specification should not be construed as a limitation of this utility model.
