[0052] The track spike gripping tooling drive device 402 and the insulating gauge block operating tooling drive device 403 are integrated into the main support base 404.

[0053] Each tooling is positioned laterally and vertically through an independent multi-degree-of-freedom motion unit.

[0054] The main support base 404 serves as the load-bearing foundation of the entire system, providing structural rigidity support; it bears the load of each working module and its load, and can be set as a high-strength steel or aluminum alloy frame structure, taking into account both strength and lightweight; the under-rail component operating tooling drive device 401 is used to clamp, lift, and place under-rail elastic pads, support blocks and other components; it can be set as a pneumatic / hydraulic gripper, a double-sided synchronous clamping mechanism, or a lifting device with guide sliding; it is used when replacing aging or damaged under-rail pads.

[0055] The rail spike gripping tool drive device 402 is used to grip, release or tighten rail spikes; it can be set as a self-aligning clamp, a multi-directional rotating chuck or used with an electric or pneumatic torque wrench to disassemble or install rail spikes in the fastening system, and is especially suitable for WJ-8 and WJ-7 type fasteners.

[0057] The multi-degree-of-freedom motion unit provides multiple degrees of freedom in multiple directions and can be configured as a multi-joint robotic arm, a combination of linear guide rail and ball screw, a planar XY module with Z-axis lifting, or a modular six-degree-of-freedom robot; thereby enabling precise positioning of tooling in the horizontal plane, such as aligning with target positions such as rails, rail support platforms, and fasteners.

[0058] The transition platform 400 and ballastless track fastener replacement device provided in this application embodiment have the following technical advantages compared to the prior art:

[0059] This application integrates multiple tooling fixtures onto a single main support base 404, achieving multi-functionality and significantly reducing tool change time while improving operational efficiency. Furthermore, each tooling fixture is equipped with an independent multi-degree-of-freedom motion unit, supporting precise lateral and vertical positioning to ensure accurate docking of all components. By adopting a unified main support base 404 platform, various tooling fixtures are rationally arranged, and modular control and collaborative operation are achieved using independent motion units.

[0060] In one optional embodiment, the under-rail component operating fixture drive device 401 includes a first support base 4011, a transverse first slide rail assembly 4012, a transverse first positioning drive assembly 4013, a vertical first slide rail assembly 4014, and a vertical first drive assembly 4015; the transverse first slide rail assembly 4012 is connected to the main support base 404 and the first support base 4011; one end of the transverse first positioning drive assembly 4013 is connected to the main support base 404, and the other end is connected to the first support base 4011, driving the first support base 4011 to move laterally for positioning; one end of the vertical first slide rail assembly 4014 is connected to the first support base 4011, and the other end is used to connect to the under-rail component robot; one end of the vertical first drive assembly 4015 is connected to the first support base 4011, and the other end is used to connect to the under-rail component robot, driving the under-rail component robot to move up and down.

[0061] The first support base 4011 serves as the carrier platform for the robot arm under the rail. It is used to install the lateral and vertical slide rail components and drive components. It can be made of lightweight and high-strength materials, has good rigidity and fatigue resistance, and is suitable for frequent movements.

[0062] The first transverse slide rail assembly 4012 connects the main support 404 and the first support 4011, forming a guide mechanism for transverse movement. It can be configured as a linear guide rail and a slider mechanism to ensure that the first support 4011 remains stable and highly accurate during transverse movement, and to support a stable connection and relative sliding with the main support 404.

[0063] The first lateral positioning drive component 4013 realizes active displacement control in the lateral direction. It can be set as a ball screw + servo motor, synchronous belt + servo motor, hydraulic cylinder or pneumatic cylinder. It can be used with an encoder or grating ruler to realize closed-loop control to ensure positioning accuracy, so that the robot arm of the under-rail component can accurately align with the rail support platform.

The vertical first drive assembly 4015 realizes the up and down movement of the robot arm under the rail. It can be set as a vertical ball screw, cylinder or electric push rod, etc., and can be set as needed.

[0065] The 401 track-mounted component operating tool drive device has a reasonable structural design and smooth operation, which can effectively realize the precise positioning and efficient operation of track-mounted components. It is especially suitable for the disassembly and replacement of components such as track pads and support blocks in ballastless track lines.

[0066] In one alternative embodiment, the slide rod of the transverse first slide rail assembly 4012 is fixed to the first support base 4011, and the slide body of the transverse first slide rail assembly 4012 is fixed to the main support base 404.

[0067] And / or, the slide rod of the vertical first slide rail assembly 4014 is fixed to the robot arm of the rail component, and the slide body of the vertical first slide rail is fixed to the first support base 4011.

[0068] When the first lateral positioning drive component 4013 is activated, the first support 4011 moves laterally relative to the main support 404. Compared with the setting where the guide rail is fixed to a stationary component, the above setting simplifies the structure of the main support 404 and improves the motion accuracy.

[0069] The slide bar of the vertical first slide rail assembly 4014 is fixed to the robot arm of the lower rail component, and the slide body is fixed on the first support base 4011.

This improves the guiding rigidity of the robot arm's lifting and lowering; reduces the cantilever length and improves the overall stability; and facilitates modular disassembly and replacement of different types of robot arms.

[0070] The structure is reasonably designed and has high guiding accuracy, which helps to improve the overall operational stability and positioning accuracy of the under-rail component operation tool drive device 401.

[0072] The second support base 4021 serves as the mounting foundation for the rail spike robot and its drive system; it is made of high-strength, lightweight metal or composite materials; and it can integrate auxiliary functional components such as sensors and limit switches.

[0073] The second lateral slide rail assembly 4022 provides lateral movement guidance, using linear guide rails, ball slide rails, or guide posts and sleeves; ensuring smooth movement of the road spike robot in the X / Y directions; and supporting stable connection and relative sliding with the main support 404.

[0074] The second lateral positioning drive component 4023 enables the horizontal movement of the road stud robot; it can be configured as a ball screw + servo motor, or synchronous belt + servo motor, hydraulic cylinder or pneumatic cylinder, etc.; it can be used with an encoder to achieve closed-loop control to ensure high-precision alignment; so that the road stud robot can accurately align with the road stud mounting hole position.

[0077] The spike gripping tool drive device 402 can effectively achieve precise positioning and efficient operation of spikes, and is especially suitable for the disassembly and replacement of spikes in ballastless track lines.

[0078] The second lateral positioning drive motor 40231 provides power for lateral movement and can be configured as a servo motor or a stepper motor; the gear and rack transmission pair 40232 is used for linear reciprocating motion control. The rack is fixed to the top wall of the main support 404, and its length should cover the entire lateral formation required by the tooling. The drive gear is fixed to the second lateral positioning drive motor 40231. The second lateral positioning drive motor 40231 drives the drive gear to rotate. It is connected through a coupling or reducer, which helps to improve transmission efficiency and response speed.

[0079] In one embodiment, the slide rod of the transverse second slide rail assembly 4022 is fixed to the main support base 404, and the slide body of the transverse second slide rail assembly 4022 is fixed to the second support base 4021; when the transverse second positioning drive drives the second support base 4021 to move, the slider slides along the guide rail to achieve smooth transverse movement.

[0080] In one optional embodiment, the insulated gauge block operating fixture drive device 403 includes:

[0081] Third support 40311;

[0082] The transverse third slide rail assembly 40312 is connected to the main support 404 and the third support 40311;

[0083] The lateral third positioning drive component 40313 is connected at one end to the main support 404 and at the other end to the third support 40311, driving the third support 40311 to move laterally for positioning.

[0084] The vertical third slide rail assembly 40314 is connected at one end to the third support base 40311 and at the other end to the insulated gauge block robot.

[0085] The vertical third drive assembly 40315 is connected at one end to the third support base 40311 and at the other end to the insulated gauge block robot, driving the insulated gauge block robot to rise and fall.

[0086] The third support base 40311 serves as the mounting foundation for the insulated gauge manipulator and its motion components. The transverse third slide rail assembly 40312 provides a guiding structure for transverse movement, such as a linear guide rail, ball bearing guide rail, or guide post / sleeve, to ensure smooth sliding of the third support base 40311 on the main support base 404 and support stable connection and relative sliding between the third support base 404 and the main support base 404.

[0087] In the transverse slide rail assembly, the slide rod (i.e., the guide rail) is fixed to the third support base 40311, while the slide body (i.e., the slider) is fixed to the main support base 404. When the drive component moves the third support base 40311, the slider slides relative to the guide rail, achieving smooth transverse movement. The moving end has a guide rail to reduce error accumulation and improve positioning accuracy.
