Description

Technical Field

[0001] This invention relates to the field of ballastless track management technology, and in particular to a wire saw. Background Technology

[0002] Ballastless track structures are characterized by small deformation, high reliability, strong load-bearing capacity, low daily maintenance, and long service life, making them the main track structure type used in high-speed railways. However, due to the long-term dynamic load of trains and the complex service environment, the geometric shape of ballastless track structures on some lines has changed to varying degrees, such as arching, sinking, and offset, which seriously affects the safe operation of trains.

This ensures that the diamond cable maintains a stable cutting posture throughout the cutting process. Simultaneously, the lateral feed formed by the first drive motor and the moving mechanism allows the saw frame to advance continuously at a constant speed, eliminating the pauses and impacts caused by manual adjustment or machine displacement, significantly improving the smoothness of the cut surface. Furthermore, the diamond cable protruding from the bottom of the saw frame directly acts on the cutting surface. Combined with the dual-axis linkage adjustment capability, it can quickly align with different cutting positions, shortening auxiliary time. This improves the efficiency of track defect remediation while ensuring cutting stability, thereby solving the technical problem of unstable and inefficient cutting processes caused by the need to move the moving device of the cutting equipment during the feeding process in existing equipment.

[0026] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present application.

[0027] In the description of the embodiments of this application, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing the embodiments of 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. Therefore, they should not be construed as limitations on the embodiments of this application. In addition, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0028] In the description of the embodiments of this application, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; 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; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in the embodiments of this application based on the specific circumstances.

[0029] This embodiment provides a wire saw, which is mainly used for cutting operations during the treatment of defects such as arching, subsidence, and deviation of ballastless tracks. Its overall design concept is to provide a specialized cutting device that can achieve multi-directional precise feeding, a stable cutting process, and high operating efficiency, thereby solving the technical problem that existing track treatment equipment requires frequent movement of the entire machine during cutting, resulting in unstable cutting and low efficiency.

[0030] Please see Figures 1 to 4 The wire saw of this embodiment includes a frame serving as the mounting base. This frame forms a stable support structure, used to support and install various functional components. A first support plate 1 is provided on the side of the frame. The first support plate 1 is a flat plate structure, its surface generally perpendicular to the side of the frame, providing a mounting platform for subsequent components. Specifically, a moving mechanism is provided on the first support plate 1. The moving mechanism is a key component for adjusting the position of the second support plate 3 relative to the frame. In this embodiment, the moving mechanism is connected to a first drive motor 2 mounted on the side of the frame. The first drive motor 2 serves as a power source, and its output rotational motion is converted into linear movement of the second support plate 3 through the moving mechanism. The second support plate 3 can then smoothly displace relative to the frame in a predetermined direction under the drive of the first drive motor 2, achieving a lateral feed function.

[0031] It should be noted that the first drive motor 2 can be a three-phase asynchronous motor or servo motor with a rated power of 0.75–2.2 kW; the second drive motor 4 can be an explosion-proof AC motor or permanent magnet synchronous motor with a rated power of 3–7.5 kW. The diamond rope 5 can be detachable.

[0032] The second support plate 3 is also a plate-shaped component, with its surface perpendicular to the surface of the first support plate 1. The second support plate 3 is connected to a moving mechanism on the first support plate 1, and can slide along the side of the first support plate 1 under the guidance of this moving mechanism. This sliding guide structure ensures the linearity and stability of the movement of the second support plate 3. A second drive motor 4 is connected to the end of the second support plate 3. The output shaft of the second drive motor 4 passes through the plate body of the second support plate 3 and extends to the other side of the second support plate 3. On this other side, the output shaft of the second drive motor 4 is fixedly connected to the saw frame. The saw frame is a structure used for cutting. In this embodiment, a diamond rope 5, i.e., a beaded rope, is wound around the saw frame; this is the component that directly performs the cutting operation. The bottom of the saw frame is designed as an open structure, allowing a portion of the diamond rope 5 wound around it to protrude from the bottom, so that it can directly contact and act on the surface of the track plate or the gap at the bottom of the plate during operation.

[0033] The wire saw in this embodiment achieves the following functions: the first drive motor 2 drives the moving mechanism, which in turn drives the second support plate 3 to move, enabling the saw frame to feed in one direction in the horizontal plane; the second support plate 3 slides along the first support plate 1 under the drive of the moving mechanism, enabling the saw frame to feed in another vertical direction in the horizontal plane. This dual-axis adjustment mechanism allows the saw frame to be precisely positioned in two dimensions in the horizontal plane. More importantly, during the cutting operation, only the saw frame needs to be moved without moving the entire machine frame, avoiding the vibration, deviation, and auxiliary time consumption caused by frequent movement and re-erecting of the entire machine in traditional equipment, thereby improving the stability of the cutting process and the efficiency of operation.

[0034] In a preferred embodiment, the frame specifically includes a movable base 6. The movable base 6 serves as the foundation for the entire equipment's movement, and its bottom can be equipped with track wheels or traveling wheels to facilitate the equipment's movement along the track rails or its relocation within the site. A support column 7 is fixedly mounted on the top surface of the movable base 6. The support column 7 has an internal cavity, forming a hollow structure, which reduces weight and facilitates the housing and installation of transmission components. A first support plate 1 is connected to the side wall of the support column 7. Specifically, the first support plate 1 can be installed on the right side of the support column 7. The first drive motor 2 is located on the opposite side of the first support plate 1, i.e., the side of the first support plate 1 facing away from the support column 7, or the first drive motor 2 can be partially embedded within the first support plate 1. The moving mechanism passes sequentially through the plate body of the first support plate 1 and the side wall of the support column 7, ultimately connecting to the output end of the first drive motor 2. This layout results in a compact power transmission path and high structural integration.

[0035] Regarding the specific implementation of the moving mechanism, this embodiment provides a preferred mechanical structure. The moving mechanism includes a first threaded rod 8. The first threaded rod 8 is built into the internal cavity of the first support plate 1 along the length direction of the first support plate 1. The two ends of the first threaded rod 8 can be supported at the two ends of the first support plate 1 by bearings. A first sliding sleeve (the first sliding sleeve and the second sliding sleeve 14 have the same structure and are not shown in the figure here) is provided at the end of the second support plate 3. The first sliding sleeve is sleeved on the outer peripheral surface of the first threaded rod 8 and is threadedly engaged with the first threaded rod 8. At the same time, the upper and lower surfaces of the first sliding sleeve are in contact with the upper and lower inner walls of the first support plate 1 respectively and can slide, thereby guiding and limiting the movement of the second support plate 3. When the first threaded rod 8 rotates, the first sliding sleeve will drive the second support plate 3 to slide smoothly along the axial direction of the first threaded rod 8 (i.e., the length direction of the first support plate 1).

[0036] The installation method of the first drive motor 2 has also been optimized. The drive shaft of the first drive motor 2 extends through the top side wall of the support column 7 and into the interior of the support column 7, and is connected to a rotating block 9. The rotating block 9 is a connecting element, one end of which is fixed to the drive shaft of the first drive motor 2, and the other end is connected to the end of the first threaded rod 8, thereby transmitting the rotational power of the first drive motor 2 to the first threaded rod 8. A support plate 10 is provided at the bottom of the first drive motor 2, which is used to support the weight of the first drive motor 2. A support rod 11 is connected to the bottom surface of the support plate 10. The support plate 10 and the support rod 11 form a whole, one end of which extends out of the sliding groove opened on the side wall of the support column 7 and can slide up and down along the sliding groove, so that the first drive motor 2 can be adjusted in the vertical direction together with the support plate 10.

[0037] To achieve automatic adjustment of the saw frame height, this embodiment further incorporates a lifting mechanism. A lifting ring 12 is fitted onto the top outer circumference of the rotating block 9. A bearing can be installed between the lifting ring 12 and the rotating block 9, allowing the rotating block 9 to rotate freely relative to the lifting ring 12, while the lifting ring 12 itself does not rotate with the rotating block 9. A load-bearing cylinder 13 is fixedly connected to the bottom of the lifting ring 12. The load-bearing cylinder 13 is a hollow cylinder, with a second sliding sleeve 14 fixedly connected to its bottom. The second sliding sleeve 14 is embedded in the inner wall of the support column 7 and can slide up and down along the inner wall of the support column 7. The second sliding sleeve 14 is also fitted onto the outer circumference of the second threaded rod 15 and is threadedly engaged with the second threaded rod 15. The second threaded rod 15 is vertically positioned, and its bottom end is mounted on the top surface of the movable base 6 via a bearing, allowing it to rotate freely. A first bevel gear 16 is fitted onto the bottom outer circumference of the second threaded rod 15. The first bevel gear 16 meshes with a second bevel gear 17. The second bevel gear 17 is mounted on the output shaft of the third drive motor 18. The third drive motor 18 is fixed on the top surface of the movable base 6, and its output shaft extends through the side wall of the support column 7 into the interior of the support column 7 and is connected to the second bevel gear 17.

[0038] It should be noted that the third drive motor 18 has the same model as the first drive motor 2.

[0039] In one example, when the third drive motor 18 starts, its power is transmitted to the second threaded rod 15 through the second bevel gear 17 and the first bevel gear 16, causing the second threaded rod 15 to rotate. The rotation of the second threaded rod 15 drives the second sliding sleeve 14, which is threadedly engaged with it, to move up and down. Since the second sliding sleeve 14 is embedded in the inner wall of the support column 7 and its rotation is restricted, it can only slide vertically along the inner wall of the support column 7. The movement of the second sliding sleeve 14 drives the rotating block 9 to move up and down as a whole through the load-bearing cylinder 13 and the lifting ring 12. The movement of the rotating block 9 then drives the first drive motor 2 to slide up and down along the slide groove through the bearing plate 10 and the support rod 11. Finally, the up and down movement of the first drive motor 2 is transmitted through the rotating block 9 and the first threaded rod 8, enabling the first support plate 1 and the second support plate 3 on it, as well as the saw frame as a whole, to achieve height adjustment. This design allows the saw frame to not only have two-dimensional movement capability in the horizontal plane, but also vertical adjustment capability, greatly enhancing the adaptability of the equipment to different cutting positions and cutting angles.

[0040] To ensure the long-term stable operation of the lifting mechanism, an oil storage tank 19 is fixedly installed on the bottom surface of the support plate 10. The oil storage tank 19 stores lubricating oil. The oil storage tank 19 is connected to the lubrication points via an oil supply pipe 20. Specifically, one end of the oil supply pipe 20 is connected to the oil storage tank 19, and the other end passes through the inner wall of the support column 7 and extends into the internal cavity of the lifting ring 12. In this way, the lubricating oil can be delivered to the bearings and other friction pairs between the lifting ring 12 and the rotating block 9, achieving automatic lubrication.

[0041] To achieve automatic extrusion of lubricating oil, a pressing rod 21 is connected to the bottom of the oil storage tank 19. The upper end of the pressing rod 21 is connected to the bottom of the oil storage tank 19 (which can be a flexible bladder or a piston structure), and is used to compress the oil storage tank 19 and extrude lubricating oil when the pressing rod 21 moves upward. A protective plate 22 is fixedly installed on the side of the support column 7. A fixed cylinder 23 is provided on the top surface of the protective plate 22. The fixed cylinder 23 is vertically installed and its bottom is closed. The bottom end of the pressing rod 21 extends downward into the interior of the fixed cylinder 23. A return spring 24 is provided at the bottom of the inner part of the fixed cylinder 23. The top end of the return spring 24 abuts against the bottom end of the pressing rod 21. A limiting edge is provided at the opening of the fixed cylinder 23 to prevent the pressing rod 21 from coming out. A limiting block is provided at the bottom end of the pressing rod 21, which cooperates with the inner wall of the fixed cylinder 23 to ensure that the pressing rod 21 remains vertical when sliding up and down.

[0042] In one example, when the third drive motor 18 drives the saw frame to descend, the support plate 10 descends, causing the pressing rod 21 to move downwards. The pressing rod 21 compresses the return spring 24, and simultaneously, under the stress of the return spring 24, it presses the oil reservoir 19, causing the lubricating oil in the reservoir 19 to be forced out through the oil delivery pipe 20 and drip onto the friction pair inside the lifting ring 12. When the saw frame rises, the support plate 10 moves up and down, and the pressing rod 21 returns to its original position under the elastic force of the return spring 24, stopping the pressing and lubrication. The lubrication action is synchronized with the lifting action of the saw frame, and an appropriate amount of lubricating oil is automatically replenished with each descent, achieving on-demand lubrication, ensuring the lubrication effect, and avoiding the waste of lubricating oil.

[0043] It should be noted that the oil storage tank 19 is equipped with an inlet for injecting a small amount of oil into it for single use only. This eliminates the need for manual injection of oil into the support column 7, thus improving the convenience of oil replenishment.

[0044] To achieve automatic adjustment of the saw frame posture, particularly the switching between horizontal and vertical cutting, this embodiment provides a first rotating roller 25 at the bottom of the first support plate 1. The first rotating roller 25 can be a roller shaft extending along the length of the first support plate 1, with both ends mounted to the bottom of the first support plate 1 via bearings. Similarly, a second rotating roller 26 is provided at the bottom of the second support plate 3. The second rotating roller 26 extends along the length of the second support plate 3, with both ends mounted to the bottom of the second support plate 3 via bearings.

[0045] The first roller 25 has a first external tooth 27 on its outer circumferential surface. Simultaneously, a second external tooth 28 is correspondingly provided on the outer circumferential surface of the first threaded rod 8. The first external tooth 27 and the second external tooth 28 are connected by an elastic toothed ring 29. The elastic toothed ring 29 is an elastic annular toothed band that can be tensioned and fitted onto the first external tooth 27 and the second external tooth 28 to achieve transmission between them. An opening is provided at the bottom of the first support plate 1, allowing the elastic toothed ring 29 to pass through and move freely. Thus, when the first threaded rod 8 rotates, the second external tooth 28 on it drives the first roller 25 to rotate synchronously via the elastic toothed ring 29. When it is not necessary to adjust the angle of the saw frame, the annular toothed band is pulled open, preventing the first external tooth 27 and the second external tooth 28 from connecting.

[0046] A third bevel gear 30 is also provided at the end of the first roller 25. A fourth bevel gear 31 is correspondingly provided at one end of the second roller 26. The third bevel gear 30 and the fourth bevel gear 31 mesh with each other, thereby realizing the vertical shaft transmission between the first roller 25 and the second roller 26. A worm gear 32 is connected to the other end of the second roller 26. The worm gear 32 rotates synchronously with the second roller 26. A worm wheel 33 is rotatably mounted on the second support plate 3 via bearings. The worm wheel 33 meshes with the worm gear 32, forming a worm wheel 33 and worm gear 32 transmission pair. An adjusting gear 34 is provided on the saw frame. The adjusting gear 34 is coaxially arranged with the worm wheel 33 or meshes with it through an intermediate gear. When the worm wheel 33 rotates, it will drive the adjusting gear 34 to rotate.

[0047] The adjusting gear 34 is connected to a rotatable component of the saw frame (such as the main disc 35 mentioned later). When the first threaded rod 8 rotates to drive the second support plate 3 to move laterally, its rotational power is extracted synchronously and transmitted sequentially through the elastic gear ring 29, the first rotating roller 25, the third bevel gear 30, the fourth bevel gear 31, the second rotating roller 26, the worm 32, and the worm wheel 33 to the adjusting gear 34, ultimately driving the saw frame to rotate around its axis (i.e., the output shaft axis of the second drive motor 4). This couples the linear feed motion of the second support plate 3 with the rotational motion of the saw frame. When switching from horizontal to vertical cutting, simply controlling the first drive motor 2 to move the second support plate 3 a certain distance automatically completes the 90-degree rotation of the saw frame, without the need for an additional drive motor and control program. The structure is simple and the operation is reliable. The design of the elastic gear ring 29 allows for a certain angular deviation or elastic deformation during transmission, ensuring the smoothness and adaptability of the transmission.

[0048] It should be noted that the portion of the first threaded rod 8 near the support column 7 is disconnected. To drive the first threaded rod 8 to rotate as a whole, a U-shaped pin is inserted into the two sections to make them a single unit.

[0049] In addition, when adjusting the angle of the saw frame, the fourth bevel gear 31 needs to be driven to mesh with the third bevel gear 30 through the first threaded rod 8, and the U-shaped pin needs to be disengaged before the angle of the saw frame can be adjusted.

[0050] In this embodiment, the saw frame includes a main disc 35 and two symmetrical auxiliary discs 36. The main disc 35 is located in the center, and the two auxiliary discs 36 are located on the left and right sides of the main disc 35, respectively, forming an approximately triangular frame. A diamond rope 5 is wound between the main disc 35 and the two auxiliary discs 36, forming a closed cutting loop between the main disc 35 and the auxiliary discs 36. The main disc 35 has a built-in rotating core 38, which is fixedly connected to the output shaft of the second drive motor 4. Therefore, the main disc 35 itself does not rotate; it is the rotating core 38 that rotates, and the rotation of the rotating core 38 drives the diamond rope 5 to move at high speed. The main disc 35 is fixed to the front of the adjusting gear 34 by bolts or welding. The main disc 35 and the two auxiliary discs 36 are connected by a hollow plate 41. The hollow plate 41 has a hollow structure to reduce its weight, while also serving as a connection and support, maintaining the relative position stability between the main disc 35 and the auxiliary discs 36.

[0051] It should be noted that multiple ball bearings are installed between the rotating core 38 and the main disc 35, so that the main disc 35 does not rotate when the second drive motor 4 drives the rotating core 38. The main disc 35 is only used to adjust the tilt angle of the diamond rope 5.

[0052] To achieve cooling and dust reduction during the cutting process, a peristaltic block 37 is installed in front of the main disk 35. The peristaltic block 37 is connected to the rotating core 38 inside the main disk 35, so the peristaltic block 37 rotates together with the rotating core 38. A convex ring plate 39 is also fixedly installed in front of the main disk 35. The convex ring plate 39 is an annular plate surrounding the central hole of the main disk 35. A water pipe 40 is installed between the convex ring plate 39 and the peristaltic block 37. A portion of the water pipe 40 is suspended inside the cavity plate 41 and extends along the length of the cavity plate 41. Multiple water spray holes are opened on the bottom surface of the water pipe 40, which are directed towards the cutting area of ​​the diamond rope 5. A water supply pipe 42 is connected to the top of the water pipe 40, and the other end of the water supply pipe 42 is connected to a water storage tank 43 located on the top of the frame. The water storage tank 43 is used to store cutting water.

[0053] During operation, water in the storage tank 43 is pressurized by the peristaltic block 37, and then flows into the water pipe 40 through the water supply pipe 42. The water is then evenly sprayed from the spray nozzles at the bottom of the water pipe 40 onto the high-speed moving diamond rope 5, achieving cooling and rinsing of the diamond rope 5 and the cutting point. Since the water pipe 40 is positioned between the convex ring plate 39 and the rotating peristaltic block 37, the rotation of the peristaltic block 37 causes the water pipe 40 to slightly peristalse or oscillate, resulting in a periodic change in the spray direction of the spray nozzles. This allows for more even coverage of the entire cutting area, improving cooling and dust suppression. The water pipe 40 is suspended in the cavity plate 41, which serves to contain and protect it.

[0054] Furthermore, a crossbeam 44 is provided between the two cavity plates 41. The crossbeam 44 is a transverse support rod or plate, with both ends fixedly connected to the inner sides of the two cavity plates 41 respectively. The bottom or side of the water pipe 40 can rest on the crossbeam 44, or be guided by the crossbeam 44, to ensure that the water pipe 40 can swing stably when driven by the peristaltic block 37, avoiding excessive shaking or displacement.

[0055] In one embodiment, the main disk 35 has multiple first positioning holes 45, which are distributed along the circumference of the main disk 35 or a specific trajectory. The cavity plate 41 is rotatably connected to the main disk 35, for example, via a hinge or pivot, allowing the cavity plate 41 to rotate relative to the main disk 35, thereby changing the distance between the auxiliary disk 36 and the main disk 35. The cavity plate 41 has correspondingly multiple second positioning holes 46. After the auxiliary disk 36 is adjusted to the desired position, the first positioning holes 45 and second positioning holes 46 are aligned, and then positioning bolts are inserted for fixation. By selecting different first positioning holes 45 and second positioning holes 46 to engage, the unfolding angle of the cavity plate 41 can be changed, thereby adjusting the distance between the main disk 35 and the auxiliary disk 36, i.e., changing the size and shape of the cutting loop formed by the diamond rope 5, to accommodate track plates of different thicknesses or cutting depths.

[0056] Before cutting the track slab, the equipment is first moved along the rail to the cutting position using the movable base 6 at the bottom of the frame. According to the cutting requirements, the third drive motor 18 is started, which, through components such as the second threaded rod 15 and the second sliding sleeve 14, drives the first support plate 1 and its saw frame to rise and fall as a whole, adjusting the cutting height of the diamond rope 5 to the predetermined position. Simultaneously, the first drive motor 2 drives the first threaded rod 8 to rotate, causing the second support plate 3 to slide along the first support plate 1, adjusting the horizontal position of the saw frame so that the diamond rope 5 is aligned with the cutting starting point.

[0057] Depending on the cutting method (horizontal or vertical cutting), the first drive motor 2 drives the second support plate 3 to move a specific distance, and the linkage mechanism (first rotating roller 25, second rotating roller 26, worm gear 33, worm 32, etc.) automatically drives the saw frame to rotate to the required posture. For example, when performing horizontal cutting, the diamond rope 5 is placed in the horizontal plane; when performing vertical cutting, the diamond rope 5 is rotated 90 degrees to be placed in the vertical plane.

[0058] During the cutting process, the second drive motor 4 is activated, driving the diamond rope 5 to rotate at high speed via the rotor 38. Simultaneously, the water spray system is activated, with water from the storage tank 43 sprayed onto the diamond rope 5 through the water supply pipe 42 and the water pipe 40. The first drive motor 2 drives the first support plate 1 to move laterally, achieving lateral feed cutting of the saw frame; the sliding of the second support plate 3 achieves longitudinal feed cutting of the saw frame. When horizontally cutting the bottom of the track plate, the feed motion mechanism can be combined with the rail support platform as the reaction point to drive the traveling platform to continuously feed along the rail, completing the horizontal cutting of the entire plate section. After prolonged cutting operations, automatic lubrication replenishes lubricating oil to the lifting transmission components.

[0059] When it is necessary to change the cutting direction or position, simply adjust the position or posture of the saw frame using the first drive motor 2 or the third drive motor 18. Without moving the entire machine, the new cutting point can be quickly and accurately aligned for continuous operation. After cutting is completed, the saw frame is reset, and the equipment is moved away from the site using the movable base 6.
