Description

Technical Field

[0001] This utility model relates to the field of rail grinding technology, and in particular to a rail grinding vehicle. Background Technology

[0002] Under the influence of wheel-rail contact stress, rails will inevitably develop defects, such as edge thickening and side wear, as well as surface contact fatigue cracks. If these defects are not eliminated in time, they will gradually aggravate and affect the service life of the rails and the quality of vehicle operation.

[0003] Rail grinding machines have become the main maintenance equipment for controlling rail defects. However, currently, their use is mainly for repairing rail profiles and incidentally eliminating contact fatigue cracks on the rail surface. Rail profile inspection is currently mainly carried out by personnel carrying profiles before and after operation. The inspection data is greatly affected by human factors and there are potential safety hazards on the line. Contact fatigue crack inspection on the rail surface is not currently carried out in the field.

[0004] With existing grinding methods, situations arise where the rail profile is repaired but surface contact fatigue cracks are not completely eliminated. Under the influence of wheel-rail contact stress, these cracks continue to propagate and worsen, failing to truly eliminate rail defects. Therefore, developing a rail grinding vehicle capable of both rail profile detection and surface defect detection is of great significance for improving rail grinding quality. Utility Model Content

[0006] To achieve the above objectives, this utility model provides the following technical solution: a rail grinding vehicle, comprising a power frame and a grinding frame, wherein reinforcing rods are fixedly connected to both sides of the top of the grinding frame, a rotating component is rotatably connected to one end of the grinding frame, a spacing adjustment assembly is provided on the outer wall of the rotating component, the spacing adjustment assembly is used to adjust the distance between the grinding frames, wheels are provided at both ends of the reinforcing rods, a second slide rail is passed through and fixedly connected to the top of one end of the reinforcing rod, a first slide rail is passed through and fixedly connected to the bottom of one end of the reinforcing rod, a driving structure is fixedly connected between the first slide rail and the second slide rail, a first lead screw is fixedly connected to the output end of the driving structure, a third slide rail is threadedly connected to the outer ring of the first lead screw, a third reducer is fixedly connected to the top of the third slide rail, a second servo motor is fixedly connected to one end of the third reducer, and the output end of the second servo motor is fixedly connected to the input end of the third reducer, a second lead screw is fixedly connected to the output end of the second servo motor, a mounting plate is threadedly connected to the outer ring of the second lead screw, and a grinding assembly is provided at one end of the mounting plate.

[0007] By adopting the above technical solution, the reinforcing rod not only enhances the structural strength of the grinding frame and ensures stability during the grinding process, but also allows the wheels at both ends to move along the track, enabling the grinding vehicle to travel on the rails. The cooperation of the first slide rail, the second slide rail, the drive structure, the first lead screw, and the third slide rail can drive the third slide rail to move vertically along the reinforcing rod, thereby driving the mounting plate and grinding components to adjust their height to meet the needs of rail grinding under different working conditions.

[0012] As a further description of the above technical solution: a connecting rod is rotatably connected between the bottom of the adjusting plates, and the connecting rod is rotatably connected to the bottom reinforcing rod.

[0017] By adopting the above technical solution, the first servo motor drives the grinding wheel to rotate at high speed to achieve grinding treatment on the surface of the rail. The mounting plate is used to fix the first servo motor and the grinding wheel to ensure that the grinding wheel maintains a stable position and angle during operation, thereby ensuring grinding quality and precision and improving grinding efficiency.

[0018] As a further description of the above technical solution: a generator is fixedly connected to one side of the top of the power supply vehicle frame, and a control cabinet is fixedly connected to the other side of the top of the power supply vehicle frame.

[0019] By adopting the above technical solution, the generator provides power support for the entire grinding vehicle, ensuring the normal operation of electrical equipment such as the power frame, drive structure, and servo motor; the control cabinet is used to control the operation of various components of the grinding vehicle, making it convenient for operators to operate and monitor the grinding vehicle, and realizing the automated and intelligent operation of the grinding vehicle.

[0020] As a further description of the above technical solution: the outer rim of the wheel is provided with a track, and support frames are fixedly connected to both sides of the bottom of the reinforcing rod at one end.

[0021] By adopting the above technical solution, the track provides a travel path for the wheels, ensuring that the grinding vehicle moves smoothly along the rail; the support frame is fixed on both sides of the bottom of the reinforcing rod, which plays the role of supporting and stabilizing the grinding frame, preventing the grinding frame from tilting or shaking due to uneven force during operation, thus improving the overall stability and safety of the grinding vehicle.

[0023] 1. In this utility model, the grinding component firstly adopts a combination of multiple servo motors and reducers. The third servo motor drives the mounting plate to rotate through the second reducer, and the first servo motor drives the grinding wheel to rotate at high speed.
