Description

Technical Field

[0001] This application relates to the field of train maintenance technology, and in particular to a disassembly and assembly device and a disassembly and assembly method. Background Technology

[0002] The brake lever is a key component in a brake system, responsible for its braking function. The lever body is typically made of cast iron or carbon steel and has a cylindrical structure. It functions through reciprocating motion. Taking train brakes as an example, when the air pressure is reduced, the lever extends, engaging the brake shoes to grip the wheels, slowing the train to a stop. When the pressure is increased, the lever retracts, the brake shoes disengage from the wheels, and the train resumes operation. During locomotive maintenance, the pressure maintenance of the unit brake is a crucial factor in assessing the efficiency of locomotive maintenance operations and directly impacts the locomotive's on-line service rate. The time required for unit brake lever installation and removal is a key indicator of unit brake maintenance performance. Therefore, during routine maintenance of unit brakes, it is essential to quickly replace and adjust the lever mechanism. This replacement data is one of the standards for evaluating the quality of unit brake maintenance operations.

[0003] During actual brake lever assembly and disassembly operations, the working environment is diverse and manual labor is limited. The maintenance yard, being an outdoor area, has uneven ground. Furthermore, due to the high stiffness and elasticity of the brake lever springs, the spring pressure is high, making alignment difficult. Currently, the company uses manual spring compression for replacing unit brake levers, typically requiring two or more workers. During operation, one person applies force to compress the spring until it reaches the appropriate working height, at which point another worker inserts the pin to complete the lever replacement. This method is inefficient and physically demanding. Summary of the Invention

[0004] Therefore, it is necessary to provide a disassembly and assembly device to address the problems of diverse working environments and limited manual operation during the disassembly and assembly of brakes, the high stiffness and elasticity of brake springs, the high pressure of brake springs, the difficulty in alignment, and the low efficiency and high labor intensity of manual replacement operations.

Many specific details are set forth in the following description to provide a thorough understanding of this application. However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.

[0032] In the description of this application, it should be understood that if terms such as "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential" appear, these terms indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

[0033] Furthermore, where the terms "first" and "second" appear, these terms are for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined with "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this application, where the term "multiple" appears, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0034] In this application, unless otherwise expressly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise expressly limited. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0035] In this application, unless otherwise expressly specified and limited, the use of descriptions such as "above" or "below" the second feature indicates that the first and second features are in direct contact or indirect contact via an intermediate medium. Furthermore, "above," "on top of," and "over" the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature.

[0036] It should be noted that if an element is referred to as being "fixed to" or "set on" another element, it can be directly on the other element or there may be an intervening element. If an element is considered to be "connected to" another element, it can be directly connected to the other element or there may be an intervening element. If so, the terms "vertical," "horizontal," "upper," "lower," "left," "right," and similar expressions used in this application are for illustrative purposes only and do not represent the only possible implementation.

[0037] See appendix Figure 1 - Appendix Figure 6 , attached Figure 1 A schematic diagram of the overall structure of a disassembly and assembly device according to an embodiment of this application is shown. This device is used for a locomotive's unit brake. The unit brake includes a brake disc and a brake spring. The brake spring is used to limit and buffer the brake disc. The disassembly and assembly device includes: a housing 2; a stepping cylinder 3 located inside the housing 2 for compressing the brake disc; and multiple adjusting legs 1 located on the side of the housing 2 facing the direction of gravity for adjusting the height of the housing 2 and the stepping cylinder 3.

[0038] The stepper cylinder 3 has a compression disc 4 at its output end, which is used to fit with the brake wheel disc. Multiple fixed chains 8 are installed on the housing 2, and a hanging piece 9 is movably installed at the end of the fixed chain 8. Multiple hanging holes are opened on the unit brake. Multiple hanging pieces 9 are set in correspondence with multiple hanging holes. During disassembly and assembly operations, the hanging pieces 9 are installed in the corresponding hanging holes.

[0039] During operation, the device is pushed to the side of the locomotive unit brake, and the height difference between the compression disc 4 and the brake wheel disc is observed. The adjusting cylinder inside the adjusting leg 1 is activated, and the piston rod extends and retracts, causing the support base 101 to rise and fall, thereby adjusting the overall height of the device. Adjustment is stopped when the center of the compression disc 4 is flush with the center of the brake wheel disc, or when the contact surfaces are perfectly aligned.

[0040] After alignment, the equipment needs to be secured to prevent displacement during disassembly and ensure stable clamping and disassembly. Locate the pre-set hanging holes on the unit brake and insert the various hanging parts 9 on the equipment one by one into the corresponding holes, ensuring balanced force. Send a command to the relay 6 via the control unit 7. The relay 6 activates the stepping cylinder 3, driving the cylinder piston rod to extend. The piston rod pushes the compression disc 4 towards the brake wheel until the contact surface of the compression disc 4 is tightly fitted and pressed against the brake wheel. Locate the retaining pin on the brake spring and remove it with a special tool. After removing the retaining pin, the constraint of the brake spring is released, and the brake can now be directly removed from the unit brake.

[0041] See appendix Figure 1 - Appendix Figure 3 The adjustable leg 1 has an adjustable cavity inside, and an adjustable cylinder is installed inside the adjustable cavity. The output end of the adjustable cylinder is equipped with a support seat 101 for supporting the box body 2.

[0042] In some embodiments, the combination of the adjusting cavity of the adjusting leg 1, the adjusting cylinder, and the support base 101 constitutes a height-adjustable support system. Its core function is to achieve height adjustment and stable support of the housing 2 via cylinder drive. The adjusting cavity is located inside the adjusting leg 1, accommodating and protecting the adjusting cylinder. It provides a closed installation space for the adjusting cylinder, preventing damage to the cylinder piston and piston rod from external dust, impurities, or collisions, thus extending the cylinder's service life.

[0043] The inner wall of the adjusting cavity can cooperate with the cylinder body or piston rod of the adjusting cylinder to restrict the cylinder output end to move only in the vertical direction, prevent lateral deviation during lifting and lowering, and ensure the accurate lifting trajectory of the support 101. As a load-bearing component, the internal cavity structure of the adjusting leg 1 can be reasonably designed, such as with wall thickness distribution and reinforcing ribs, to improve overall rigidity and prevent deformation of the adjusting leg 1 due to the weight of the housing 2 or external forces.

[0044] In some embodiments, the extension and retraction of the cylinder piston rod directly drives the support base 101 to move up and down, thereby adjusting the overall height of the housing 2. Furthermore, by controlling the extension and retraction of a single cylinder, the height and angle of the housing 2 can be flexibly adjusted to adapt to different ground flatness and operational requirements. If the ground is uneven, the housing 2 can be kept level through the independent adjustment of multiple adjusting legs 1, preventing tilting that could lead to uneven stress on internal components.

[0045] See appendix Figure 4 The compression disc 4 is provided with a telescopic seat 401 on the side facing the direction of gravity. The telescopic seat 401 has a telescopic cavity 402 perpendicular to the direction of gravity. A support plate 403 is slidably installed in the telescopic cavity 402, and the support plate 403 is used to limit the movement of the slewing disc.

[0046] In some embodiments, the combination of the telescopic cavity 402 and the support plate 403 is an adjustable precision limiting mechanism, and the support plate 403 can flexibly adapt to different specifications of swivel discs.

[0047] See appendix Figure 4 The pallet 403 has an arc-shaped part on the side away from the direction of gravity. The outer wall of the pallet 403 facing the stepping cylinder 3 has a first limiting boss 404 and the outer wall of the pallet 403 away from the stepping cylinder 3 has a second limiting boss 405. The outer wall of the compression disc 4 has an anti-slip groove 406.

[0048] In some embodiments, when the compression disc 4 is attached to and pressed against the brake wheel, a support plate 403 is designed to limit the bottom of the brake wheel to prevent accidental slippage between the compression disc 4 and the brake wheel. During disassembly and assembly, the operator manually pulls the support plate 403 outward. After the operation is completed, the support plate 403 is slid inward along the telescopic seat 401 and stored away.

[0049] The arc-shaped portion increases the contact area, avoiding localized stress concentration caused by point or line contact between the compression disc 4 and the stepper wheel, thus preventing accidental damage to the stepper wheel. The first limiting boss 404 and the second limiting boss 405 are respectively located on the sides of the support plate 403 facing and away from the stepper cylinder 3, forming a bidirectional limiting mechanism. Together, they create a safe movement range, ensuring that the movement of the support plate 403 always remains within the design range, thereby improving the stability of the system operation.

[0050] In some embodiments, the anti-slip groove 406 structure can increase the friction between the compression disc 4 and the rudder wheel, preventing slippage during compression.

[0051] See appendix Figure 5 - Appendix Figure 6 The hanging part 9 has an opening 901 and a mounting base 902. A pull rod 904 for opening and closing the opening 901 is slidably installed in the mounting base 902.

[0052] In some embodiments, during operation, when the equipment is adjusted to a height flush with the brake wheel, multiple hangers 9 are installed into corresponding mounting holes on the unit brake. To facilitate installation and improve installation efficiency, a telescopic pull rod 904 structure is designed on the hangers 9.

[0053] The engagement of the hanger 9 with the hanging hole restricts the horizontal movement of the equipment, while also helping to bear part of the equipment's weight and reducing the load on the adjusting leg 1.

[0054] See appendix Figure 5 - Appendix Figure 6The mounting base 902 has a through limiting cavity 903 inside, and the pull rod 904 is movably installed in the limiting cavity 903; a protruding ring 905 is provided at the end of the pull rod 904 facing the opening 901, and an elastic element 906 is sleeved on the outside of the pull rod 904; one end of the elastic element 906 abuts against the protruding ring 905, and the other end of the elastic element 906 abuts against the mounting base 902; a pull ring 907 is provided at the end of the pull rod 904 away from the opening 901.

[0055] In some embodiments, when the pull ring 907 is pulled down, the pull rod 904 slides along the limiting cavity 903 away from the opening 901, at which point the opening 901 opens and the elastic element 906 is compressed. When the hanger 9 is installed into the corresponding hanging hole on the unit brake, the pull ring 907 is released, and the pull rod 904 slides along the limiting cavity 903 towards the opening 901 under the action of the elastic element 906, at which point the opening 901 closes.

[0056] See appendix Figure 1 Inside the housing 2, there is also a power supply 5 and a relay 6. The power supply 5 is electrically connected to the relay 6, and the stepper cylinder 3 is electrically connected to the relay 6. Inside the housing 2, there is also a control unit 7.

[0057] In some embodiments, the power supply 5 uses a 4-24V lithium battery and provides stable power support for the entire electrical system.

[0058] Relay 6 acts as a power switch, receiving the low-voltage signals from control unit 7 and controlling the high-voltage circuit of stepper cylinder 3 by opening and closing its contacts. Control unit 7, such as a microcontroller or PLC, typically outputs relatively low current and cannot directly drive the high-power components of stepper cylinder 3. Relay 6 amplifies the signal and provides electrical isolation, protecting control unit 7 from high-voltage surges. Control unit 7 generates control commands based on a preset program or external signals and sends them to relay 6, indirectly controlling the actions of stepper cylinder 3, such as extension / retraction stroke, speed, and start / stop timing.

[0059] In some embodiments, the control unit 7 sends a command signal to the relay 6 as needed, such as an external trigger signal or an internal program. Upon receiving the signal, the relay 6 closes or opens its internal contacts, connecting or disconnecting the connection circuit between the stepper cylinder 3 and the power supply 5. After receiving power, the stepper cylinder 3 completes its extension and retraction movements according to the logic preset by the control unit 7. Throughout the process, the power supply 5 continuously supplies power to the control unit 7 and the relay 6, ensuring the continuity of the control link.

[0060] See appendix Figure 2 - Appendix Figure 3 The box 2 has a detachable top cover 201, and the outer wall of the box 2 is also equipped with multiple handles 202.

[0061] In some embodiments, the detachable structure allows the top cover 201 to no longer be a fixed enclosure, thus facilitating the maintenance of internal components. When parts are installed inside the housing 2, it is not necessary to disassemble the entire housing 2; simply removing the top cover 201 allows direct access to the internal structure, significantly reducing the difficulty of maintenance and parts replacement and saving maintenance time. During normal operation, the top cover 201 can be installed in place, providing protection against dust, water, and foreign objects.

[0062] In some embodiments, the overall weight of the box 2 in this device is relatively large. In order to facilitate handling and position adjustment, multiple handles 202 are designed to facilitate handling by one or more people, avoid tilting or slipping of the box 2 during handling, and reduce handling risks.

[0063] After being moved to the target location, the angle of the box 2 can be adjusted with the help of the handle 202 to improve the stability during use.

[0064] See appendix Figure 1 - Appendix Figure 3 A rubber pad is provided on the outer wall of the support base 101 on the side that contacts the ground; heat dissipation holes are provided on the outer wall of the box body 2.

[0065] In some embodiments, the rubber pad is designed primarily for scenarios where the equipment is in contact with the ground, improving stability and anti-slip performance. The coefficient of friction of rubber is much higher than that of metal or plastic, which increases the friction between the support base 101 and the ground, preventing the equipment from sliding due to vibration, external impact, or slight ground tilt. It is especially suitable for scenarios where the equipment vibrates during operation, preventing accidental sliding due to the operation of the stepper cylinder 3.

[0066] Furthermore, rubber is elastic and can absorb vibrations generated during equipment operation, preventing ground bumps from impacting the internal components of the equipment. On the other hand, the rubber pad can prevent sharp impurities on the ground, such as small stones and debris, from abrading the contact parts of the support base 101, thus extending its service life.

[0067] In some embodiments, the heat dissipation holes are the basic structure for heat dissipation of the equipment, used to solve the problem of heat accumulation inside the housing 2. The heat dissipation holes can realize air convection and remove heat. The working equipment inside the housing 2 will generate heat when it is running. The heat dissipation holes can allow cold air from the outside to enter the housing 2, while expelling hot air from the inside, thus preventing some components from being damaged due to high temperature overload.

[0068] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0069] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
