Description

Technical Field

[0001] The present invention belongs to the technical field of rail maintenance, and more particularly, relates to a lifting power unit of a rail laser strengthening vehicle. Background Art

[0002] Due to the interaction between wheels and rails, rails will experience severe wear during their service life, which significantly reduces their service life. As a result, a large number of rails need to be replaced every year, causing huge economic losses. Therefore, improving the service life of rails is of great significance to the operation, maintenance and repair of railways and urban rail transit.

[0003] At present, there are two main ways to increase the wear resistance of rails, improve the surface hardness of rails, and extend the service life of rails: the first is to carry out quenching process during the rail production process; the second is to use grinding equipment to repair and grind the defective parts of the rails when wear occurs during use. The first method has uneven cooling by wind and mist, which leads to uneven hardness of the rail surface, which is prone to failure such as rail surface peeling and abrasion, affecting the service life of the rails. The second method of grinding and reshaping only repairs the rail profile and reduces the adverse effects of wear on the smooth operation of trains. It cannot fundamentally improve the wear resistance of the rails, cannot strengthen existing rails, and has limited effect on extending the service life of the rails. In order to solve the above problems, a device for processing and repairing rails with lasers has emerged. However, existing laser machining and maintenance systems rely on railcars as traction control vehicles to drive the entire trainset. These railcars are powered by diesel motors, resulting in unstable speeds and low laser enhancement precision. Furthermore, the laser is fixed to the track on the vehicle's floor, allowing for only one-dimensional motion. This makes it impossible to adjust the laser head to align with the rail head as the vehicle's state changes, thus failing to guarantee enhanced accuracy. Furthermore, patents also suffer from insufficient energy supply and limited endurance. This challenge extends beyond laser machining to other rail maintenance processes, leading to the urgent need for a vehicle that can independently control laser enhancement processing. Key challenges include achieving precise trajectory and speed control. Summary of the Invention

[0004] In response to the above defects or improvement needs of the prior art, the lifting power unit of the rail laser strengthening vehicle provided by the present invention is arranged on a flatbed vehicle, and the hydraulic power mechanism of the maintenance vehicle is used as the lifting power, wherein the driving trolley body is placed at the bottom of the flatbed vehicle, and is connected to the flatbed vehicle through a support, a guide column and a guide slide, and moves up and down relative to the flatbed vehicle under the action of the hydraulic telescopic cylinder, so that the driving trolley is lowered when it reaches the working area so that the driving wheel contacts the rail and provides the laser strengthening vehicle with a stable and precise operating drive; at the same time, after the driving trolley rises until the driving wheel leaves the rail, the laser strengthening vehicle can be quickly transferred under the traction of an external rail vehicle.

[0005] To achieve the above-mentioned objectives, the present invention provides a lifting power unit for a rail laser hardening vehicle, comprising a flatbed vehicle and a container vehicle body or outdoor base mounted on top of the flatbed vehicle and equipped with laser hardening equipment, and a lifting power unit comprising a driving trolley and a hydraulic power mechanism in the laser hardening equipment;

[0027] In order to make the objectives, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only intended to illustrate the present invention and are not intended to limit the present invention. In addition, the technical features involved in the various embodiments of the present invention described below may be combined with each other as long as they do not conflict with each other.

[0028] The laser enhanced container vehicle includes a flatbed truck at the bottom and several compartments or outdoor bases on the top of the flatbed truck. Equipment including power generation equipment, hydraulic stations, air compressors, water coolers, laser generators or robotic arms are installed in the compartments or on the outdoor bases. A hook is provided at the end of the flatbed truck away from the work room. The hook can be connected to a rail car. The flatbed truck is connected to the hook through the rail car and is towed to the designated work area by the rail car.

[0029] A lifting power unit is set on the flatbed truck, which is used to accurately adjust the movement trajectory and running speed of the flatbed truck to ensure the quality of laser processing. Figure 1 It is a structural schematic diagram of a lifting power unit in a limiting system of a rail laser strengthening container vehicle body in an embodiment of the present invention. Figure 2This is a cross-sectional view of the vehicle body of a rail laser hardening container vehicle, including a lifting power unit within the vehicle's limiting system, according to an embodiment of the present invention. The lifting power unit comprises a drive trolley and a power supply mechanism, which is a hydraulic power unit built into the laser hardening vehicle, such as a hydraulic station. The drive trolley comprises a support 2101, a hydraulic telescopic cylinder 2102, a guide slide 2103, a guide column 2104, rear drive wheels 2105, a trolley frame 2106, front drive wheels 2107, a front trolley axle 2108, a front drive motor 2109, a rear drive motor 2110, and a rear trolley axle 2111.

[0030] Example 1 of driving the trolley Figure 1 As shown: the support 2101 is fixed on the top plane of the flatbed truck, and a guide slide 2103 is provided in the middle of the support 2101. The guide column 2104 is inserted into the guide slide 2103 and is loosely matched with the guide slide 2103. The guide column 2104 can move up and down along the guide slide 2103.

[0031] Preferably, an end cover is provided on the top of the guide column 2104, and the cross-sectional area of ​​the end cover is larger than the cross-sectional area of ​​the guide slide 2103, so that when the guide column 2104 moves to the bottom, the end cover can be placed on the guide slide 2103 to prevent the guide column 2104 from being separated from the guide slide 2103.

[0032] The trolley frame 2106, the front drive wheel 2107 and the rear drive wheel 2105 are all arranged under the bottom plate of the flatbed truck. The front drive wheel 2107 and the rear drive wheel 2105 are respectively fixed at both ends of the trolley frame 2106. The trolley frame 2106 is fixed to the bottom of the guide column 2104. One end of the hydraulic telescopic cylinder 2102 is fixed on the support 2101, and the other end is fixed on the trolley frame 2106. The hydraulic telescopic cylinder 2102 is extended and retracted to drive the trolley frame 2106 and the guide column 2104 to move up and down along the guide slide 2103, thereby driving the trolley frame 2106 and the front drive wheel and the rear drive wheel to rise and fall.

[0033] Example 2 of the driving trolley: The support 2101 is fixed on the top plane of the flatbed truck. A guide column is fixed in the middle of the support 2101. The top of the guide column passes through the support and is fixed in the support, and the bottom extends to the trolley frame. The front drive wheel and the rear drive wheel are arranged at both ends of the trolley frame. A through guide slide is provided in the middle of the trolley frame at the position corresponding to the guide column. The guide column is inserted into the guide slide and has a clearance fit with the guide slide. One end of the hydraulic telescopic cylinder is fixed to the support and the other end is fixed to the trolley frame. The hydraulic telescopic cylinder drives the trolley frame to slide along the guide column, thereby realizing the lifting and lowering of the driving trolley. Preferably, a bottom support is provided at the bottom of the guide column, and the cross-sectional area of ​​the bottom support is larger than the cross-sectional area of ​​the guide slide, so that the driving trolley will not be separated from the guide column when it slides to the lowest point.

[0034] A front trolley axle is located between the two front drive wheels of the trolley frame, and a rear trolley axle is located between the two rear drive wheels. A front drive motor is installed on the front trolley axle, and a rear drive motor is installed on the rear trolley axle. The front and rear drive motors are used to control the movement trajectory and speed of the drive trolley. The hydraulic telescopic rods on the drive trolley, as well as the guide columns and guide slides, work together to lower the drive trolley when it reaches the work area, allowing the drive wheels to contact the rails and provide a smooth and precise operation drive for the laser hardening vehicle. At the same time, the drive trolley can also be raised until the drive wheels leave the rails, allowing the laser hardening vehicle to be quickly transferred under the traction of an external rail vehicle.

[0035] The above-mentioned lifting power unit is suitable for laser strengthening vehicles, and is also suitable for other types of rail maintenance vehicles. Any vehicle involving individual precision driving can be driven by the lifting power unit.

[0036] Here are some examples of usage scenarios, Example 1: Figure 3 It is a front view of the laser strengthening vehicle component in the limiting system of the rail laser strengthening container vehicle body in an embodiment of the present invention. Figure 4 This is a top view of the laser strengthening vehicle component in the limiting system of the rail laser strengthening container vehicle body in the embodiment of the present invention. Figure 3 and Figure 4 As shown, the intermediate-drive containerized rail laser strengthening vehicle includes a flatbed 26 disposed at the bottom, a first container body 1, and a second container body 15. The first container body 1 and the second container body 15 are disposed on top of the flatbed 26. A driving trolley 21 is disposed at the bottom of the flatbed 26. The driving trolley 21 is used to precisely adjust the motion trajectory and speed of the flatbed 26. After the railcar moves the flatbed 26 to the operating area, the railcar separates from the flatbed 26 and the driving trolley 21 is opened. The driving trolley 21 precisely controls the flatbed 26, thereby making laser processing more accurate. Preferably, the driving trolley 21 is provided with a lifting mechanism. When the railcar is towing, the bottom of the driving trolley 21 is higher than the rail surface. When the driving trolley 21 is started, its bottom is lowered to the rail surface.

[0037] A hook 28 is provided at the end of the flatbed trolley 26 away from the work area. The hook 28 can be connected to the rail car. The rail car is connected to the hook 28 and then connected to the flatbed trolley 26. The rail car is used to tow the flatbed trolley 26 to the designated work area, and at the same time, the first container body 1 and the second container body 15 on the flatbed trolley 26 are driven to the work area.

[0038] The first container body 1, the second container body 15, and the flatbed truck 26 are independently separable from each other, and the first and second container bodies 1, 15 are detachably connected to the flatbed truck 26. During the manufacturing process of this containerized laser hardening vehicle, the three independent components can be manufactured and debugged simultaneously, requiring only pre-reserved interfaces for docking. This reduces the amount of flatbed truck 26 required for this process, significantly shortening the manufacturing process. After the first and second container bodies 1, 15 are separated from the flatbed truck, they can be conveniently debugged or repaired in the workshop without interfering with each other. Both can be transported by car to a nearby work area and then transferred to the flatbed truck for installation using a crane. Furthermore, the first container body 1, the second container body 2, and the flatbed truck 26 are all modular in design. If a component fails, it can simply be replaced with an identical module, eliminating the need for a complete overhaul. This enhances the reliability of the hardening vehicle. Furthermore, the independent, separable, modular, and integrated design of the hardening vehicle simplifies manufacturing, increases transportation flexibility, facilitates debugging and repair, and enhances system reliability. The axle seat 2901 is fixed on the side walls of the first container body 1 and the second container body 15 , and the limiting cylinder 2905 is fixed on the flatbed vehicle 26 .

[0039] The first container vehicle body 1 , the second container vehicle body 15 and the flatbed vehicle 26 are all provided with electrical interfaces, through which energy and information communication can be achieved among the flatbed vehicle, the first container vehicle body 1 and the second container vehicle body 15 .

[0040] Figure 5 Schematic diagram of the separation of the container body and the flatbed of the laser strengthening vehicle in the embodiment of the present invention. Figure 4 and Figure 5As shown, a plurality of limiting columns 25 are provided on the top plane of the flatbed truck, and the limiting columns 25 are arranged at intervals, and limiting columns 25 are provided at the ends of the corresponding first container body 1 and the second container body 26; the bottoms of the corresponding first container body 1 and the second container body 15 are provided with limiting holes matching the limiting columns 25, and the first container body 1 and / or the second container body 15 are placed on the flatbed truck 26, and the first container body 1 and / or the second container body 15 are fixed on the flatbed truck 26 through the cooperation of a plurality of limiting columns 25 and the limiting holes, and the limiting of the first container body 1 and the second container body 2 is realized at the same time, to prevent the first container body 1 and / or the second container body 15 from moving relative to the flatbed truck during the movement of the flatbed truck, on the one hand to prevent the container body from sliding off the flatbed truck 26, and on the other hand to ensure the stability and accuracy of the processing process. The limiting posts and limiting rods work together. The limiting rods laterally restrict the first and second container bodies to the flatbed, sharing the force of the first and second container bodies offsetting laterally with the limiting posts. When the flatbed accelerates or decelerates, and the first and second container bodies attempt to move longitudinally, the limiting posts act as limiters, preventing the container bodies and outdoor base from longitudinally moving relative to the flatbed. The synergistic action of the limiting posts and limiting rods allows for the positioning of the detachable flatbed, container bodies, and outdoor base, ensuring a secure connection between the detachable devices and preventing separation during overall movement that could affect the laser enhancement effect.

[0041] The first container vehicle body 1 and the second container vehicle body 15 include a plurality of compartments, and partitions are provided between adjacent compartments. Preferably, doors are provided on the partitions to connect adjacent compartments.

[0042] Preferably, the partition plates are made of sound-insulating and vibration-isolating materials, so that each compartment forms an independent space to avoid mutual interference.

[0043] The compartments of the first container body 1 include a driver's room, a power generation room, an operation room and a cable room.

The generator set 4 is used to generate electricity and provide power support for driving the trolley 21 and the equipment in other compartments, thereby maximizing the autonomous power supply performance and endurance of the laser enhancement vehicle, and can be used for long-term laser processing work. The space between the second partition plate 6 and the end plate on the other side of the first container body 1 is the operating room, which is equipped with an operating table 8, a first air-conditioning outdoor unit 22, and a first air-conditioning indoor unit 7. The operating table 8 is used to send control instructions to the robot 14 during operation and the movement of the drive trolley 21. The first air-conditioning outdoor unit 22 and the second air-conditioning indoor unit 17 are used to adjust the temperature in the operating room to provide a comfortable operating environment for the staff. The top of the drive trolley 21 passes through the flatbed trolley 26 and is set in the operating room. The drive trolley 21 can be directly controlled manually or electromechanically in the operating room.

[0044] The compartments of the second container body 15 include a pressure room, a light source room, an operation room, and a cable room. The space between the third partition plate 11 and the end plate on one side of the second container body 15 is the pressure room. The pressure room is equipped with at least one water cooler 9, a hydraulic station 10, and at least one air compressor 20. The water cooler is used to circulate refrigeration for the laser generator 17. Preferably, the end of the water cooler 9 is equipped with several pipes, which are led out of the water cooler 9 and distributed around the laser generator 17 before finally merging into the water cooler 9. The hydraulic station 10 is connected to the drive trolley 21 via wires and provides hydraulic power for the ascent and descent of the drive trolley 21, thereby ensuring the power and stable drive of the drive trolley 21. The air compressor 20 provides power for the air brake of the flatbed trolley 21.

[0045] The space between the third partition plate 11 and the fourth partition plate 13 is the light source room, which is equipped with a laser generator 17, a second air-conditioning outdoor unit 30 and a second air-conditioning indoor unit 12. The laser generator 17 is used to generate the high-energy laser required for rail strengthening operations, and the second air-conditioning indoor unit 12 and the second air-conditioning outdoor unit 30 are used to provide a suitable working temperature for the light source room.

[0046] The space between the fourth partition plate 13 and the end plate on the other side of the second container body 15 is a workroom. A double door 31 is provided on the end plate on the other side of the second container body 15. The outer side of the workroom, i.e., the rear end of the vehicle, is provided with a double door 31, which is convenient for the equipment in the workroom to extend out of the workroom for close-range operations. A robot 14 is provided in the workroom near the rear end of the vehicle, and the bottom of the robot 14 is fixed on the bottom plate of the workroom; the robot 14 includes a robotic arm. Preferably, the robotic arm includes several rotatable joints with locking functions and several arm segments, and a rotatable joint with locking function is provided between two adjacent arm segments, so that the robotic arm can bend at multiple angles, so that the robotic arm can realize three-dimensional movement, and the bending shape and position can be positioned through the locking function of the joint while providing rigidity support for subsequent grasping. A laser head is mounted at the end of the robotic arm, connected to a laser generator 17. The laser light generated by the laser generator 17 is emitted through the laser head to process the rails. The robotic arm's multi-angle bending allows the laser head to be positioned close to the rails to be processed, where it precisely processes the rails using the laser light emitted by the laser head. Simultaneously, only one robot 14 is required to laser-enhance two or more rails through the rotation and adjustment of the robotic arm. The provision of a double-door 31 facilitates the extension of the robotic arm into the workroom to align with the rails. Upon completion of the work, the robotic arm is retracted into the workroom and the double-door is closed to prevent foreign matter from entering the workroom and affecting the equipment's functionality.

[0047] Preferably, a robot power cabinet 16 is further provided in the workroom for directly providing power to the robot 14 .

[0048] Preferably, the robot 14 is also provided with a visual sensor, which obtains the rail image through the visual sensor, thereby controlling and adjusting the posture of the robotic arm according to the rail image, thereby controlling the laser transmitter to align with the top surface of the rail, achieving tracking motion, and thus ensuring the accuracy of the working area.

[0049] The bottom of the first container body 1 and the second container body 15 are both provided with two layers of bottom plates, and a hollow space is set between the two layers of bottom plates.

[0050] Preferably, both the first bottom plate 23 and the second bottom plate 18 are provided with doors that open outwards, so that staff can conduct maintenance at the bottom.

[0051] The working process of the laser strengthening vehicle is as follows: connect the rail car to the hook, and use the rail car to pull the flatbed car and several compartments on the top of the flatbed car to the work area; disconnect the rail car from the hook, drive the trolley down until the drive wheel contacts the rail surface, start the drive trolley, and use the drive trolley to achieve precise control of the movement of the flatbed car and several compartments on its top; open the double doors, start the robot, rotate the robotic arm so that the laser emission head mounted on the robotic arm is aimed at the top surface of the rail, drive the trolley to start the drive motor, drive the flatbed car to drive each compartment to move at a certain speed, and perform rail strengthening operations along the line; after the operation is completed, the robot rotates the robotic arm back to the work room, closes the double doors, and drives the trolley up until the drive wheel leaves the rail; connect the rail car to the hook, and tow the laser strengthening vehicle out of the work area.

[0052] Example 2: The limiting rod 29 and limiting column 25 are also applicable to an end-driven open-type rail laser hardening vehicle. The open-type rail laser hardening vehicle comprises a flatbed, a container body, outdoor equipment, and an outdoor base. The container body and outdoor base are mounted on top of the flatbed. A drive trolley is installed at the bottom of the flatbed, which precisely adjusts the flatbed's trajectory and speed. When the railcar moves the flatbed to the work area, the railcar separates from the flatbed, and the drive trolley is deployed. The drive trolley precisely controls the flatbed, thereby enhancing laser processing accuracy. Axle seat 2901 is fixed to the side wall of the container body or on both sides of the outdoor base, and limiting cylinder 2905 is fixed to the flatbed 26.

[0053] A hook is provided at the end of the flatbed truck away from the work room. The hook can be connected to the rail car. The rail car is connected to the hook and then to the flatbed truck. The rail car is used to tow the flatbed truck to the designated work area, and at the same time, the container body and outdoor base on the flatbed truck are driven to the work area.

[0054] The outdoor base, container body and flatbed truck are independently and detachably arranged, and the container body and outdoor base are detachably connected to the flatbed truck. Electrical interfaces are provided on the container body, outdoor base and flatbed truck, and energy and information communication among the flatbed truck, container body and outdoor base can be achieved through the electrical interfaces.

[0055] A matching structure of limiting columns is provided between the flatbed, the container body, and the outdoor base. Several limiting columns are provided on the top plane of the flatbed, and the limiting columns are arranged at intervals. Limiting columns are provided at the ends of the corresponding container body and the outdoor base. Limiting holes matching the limiting columns are provided at the bottom of the corresponding container body and the outdoor base. The container body and / or the outdoor base are placed on the flatbed, and the container body and / or the outdoor base are fixed to the flatbed through the cooperation of the limiting columns and the limiting holes. At the same time, the horizontal position of the container body and the outdoor base is limited to prevent the container body and / or the outdoor base from moving relative to the flatbed during the movement of the flatbed. This prevents the container body from sliding off the flatbed, and ensures the stability and accuracy of the processing process. The limiting posts and limiting rods work together. The limiting rods restrain the container body and outdoor base laterally on the flatbed, sharing the force of the limiting posts when the container body and outdoor base deviate laterally. When the flatbed accelerates or decelerates, and the container body and outdoor base attempt to move longitudinally, the limiting posts act as a limiter, preventing the container body and outdoor base from moving longitudinally relative to the flatbed. The synergistic action of the limiting posts and limiting rods allows for the positioning of the detachable flatbed, container body, and outdoor base, ensuring a well-fixed connection between the detachable devices and preventing separation during overall movement that could affect the laser enhancement effect.

[0056] The container vehicle body includes a plurality of compartments, and partition plates are provided between adjacent compartments. Preferably, the partition plates are provided with doors, and the adjacent compartments are connected through the doors.
