Description
Technical Field
[0001] This invention relates to the field of railway track slab laying equipment technology, and more specifically to a vibration reduction structure and method for reducing the feedback error of track slab fine-tuning detection. Background Technology
[0002] Track slabs are slab-shaped components used to support and fix steel rails, distributing the load transmitted by trains through the rails to the underlying base. They are extremely important in the construction and laying of railway track slabs. During railway track slab laying, elevation laser displacement monitoring sensors are often used to detect track slab parameters along the Z-axis, and lateral laser displacement monitoring sensors are used to detect track slab parameters along the X-axis. If the drive frame structure lacks vibration damping, the stability of the detection sensors will be compromised.
[0003] Therefore, how to provide a vibration reduction structure and method to reduce the vibration of the detection sensor, ensure the stability of the detection sensor, and reduce the feedback error of the track slab fine-tuning detection is one of the technical problems that urgently need to be solved in this field. Summary of the Invention
[0004] In view of this, the present invention provides a vibration damping structure and method for reducing the feedback error of track slab fine-tuning detection. The purpose is to address the aforementioned shortcomings.
[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:
[0006] A vibration damping structure for reducing the feedback error of track slab fine-tuning detection includes a frame, a slide rail, and a sensor support frame. The frame has two connecting rods, and the slide rail connects the two connecting rods, with a groove inside the slide rail and the groove opening downwards. The top of the sensor support frame is slidably connected to the groove, and the side wall of the sensor support frame has an extension wing. The extension wing is connected to a first telescopic member, the free end of which is connected to a first connecting plate. An elevation laser displacement monitoring sensor is mounted on the first connecting plate. The bottom of the sensor support frame is connected to a second telescopic member, the free end of which is connected to a second connecting plate. A lateral laser displacement monitoring sensor is mounted on the second connecting plate.
[0007] Preferably, the inner sides of both connecting rods are provided with a first groove, and the first groove matches the end of the slide rail; the end of the slide rail presses the first irregularly shaped buffer sleeve into the first groove.
[0008] Preferably, a rail plate is also connected between the two connecting rods; the rail plate has creases, and the bottom surfaces on both sides of the creases are provided with auxiliary arm travel rails.
[0009] Preferably, the crease is W-shaped.
[0010] Preferably, the inner sides of the two connecting rods are further provided with a second groove, and the second groove matches the end of the rail plate; the end of the rail plate presses the second irregularly shaped buffer sleeve into the second groove.
[0011] Preferably, it further includes: a support box, the support box being fixedly connected to the end of the top surface of the frame, the support box being used to support the air compressor, and the air compressor pressing a third irregularly shaped buffer sleeve into the support box.
[0012] Preferably, the bottom end of the frame leg is provided with a drive wheel, and the outer side wall of the frame leg is provided with an auxiliary roller assembly.
[0013] A vibration reduction method for reducing the feedback error of track slab fine-tuning detection includes the following steps:
[0014] S1. The frame travels to the work area via drive wheels and engages with the anti-collision wall via auxiliary roller assembly;
[0015] S2. The sensor support frame slides on the slide rail, moving the elevation laser displacement monitoring sensor and the lateral laser displacement monitoring sensor to the detection area.
[0016] S3. Adjust the length of the first and second telescopic components to adjust the height of the elevation laser displacement monitoring sensor and the lateral laser displacement monitoring sensor.
[0017] The present invention achieves the following technical effects compared to the prior art:
[0018] The top end of the sensing support frame is slidably connected to the groove, and the side wall of the sensing support frame is provided with an extension wing. The extension wing is connected to a first telescopic member, and the free end of the first telescopic member is connected to a first connecting plate. The first connecting plate is provided with an elevation laser displacement monitoring sensor. The bottom end of the sensing support frame is connected to a second telescopic member, and the free end of the second telescopic member is connected to a second connecting plate. The second connecting plate is provided with a lateral laser displacement monitoring sensor. The sensing support frame drives the elevation laser displacement monitoring sensor and the lateral laser displacement monitoring sensor to move synchronously, which improves the overall stability and ensures stable detection and sensing.
[0019] The rail plate has creases, and the bottom surfaces on both sides of the creases are provided with assist arm travel rails. The assist arm is connected in the assist arm travel rails. The creases can reduce the horizontal vibration of the assist arm.
[0020] The support box is used to support the air compressor. The air compressor squeezes the third irregularly shaped buffer sleeve into the support box, and the vibration between the air compressor and the support box is reduced by the third irregularly shaped buffer sleeve.
[0021] In summary, the present invention has a compact and reasonable overall structure. By driving the elevation laser displacement monitoring sensor and the lateral laser displacement monitoring sensor to move synchronously through the sensing support frame, the overall stability is improved, thereby ensuring stable detection and sensing.

[0038] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0039] Example 1
[0040] Reference Figure 1-5 This diagram illustrates a vibration damping structure for reducing feedback errors in track slab fine-tuning detection. The structure includes a frame 1, a slide rail 2, a sensor support frame 3, an elevation laser displacement monitoring sensor 4, a lateral laser displacement monitoring sensor 5, two track slabs 6, a support box 7, four air compressors 8, and four sets of auxiliary roller assemblies 9. The frame 1 contains two connecting rods 11, and the slide rail 2 is connected between these two rods. The slide rail 2 has a groove with its opening facing downwards. The top of the sensor support frame 3 is slidably connected to the groove, and its sidewall has an extension wing 31 connected to a first telescopic member 32. The free end of the first telescopic member 32 is connected to a first connecting plate 33, on which the elevation laser displacement monitoring sensor 4 is mounted. The bottom of the sensor support frame 3 is connected to a second telescopic member 34, and the free end of the second telescopic member 34 is connected to a second connecting plate 35, on which the lateral laser displacement monitoring sensor 5 is mounted. Among them, the elevation laser displacement monitoring sensor 4 is used to detect the track slab laying parameters on the Z-axis, and the lateral laser displacement monitoring sensor 5 is used to detect the track slab laying parameters on the X-axis.
[0041] The inner sides of the two connecting rods 11 are provided with first grooves, and the first grooves of the two connecting rods 11 are correspondingly arranged. Each first groove matches the end of the slide rail 2. The end of the slide rail 2 presses the first irregular buffer sleeve into the first groove, and the vibration between the connecting rod 11 and the slide rail 2 is relieved by the first irregular buffer sleeve.
[0042] Two rail plates 6 are also connected between the two connecting rods 11. The two rail plates 6 are symmetrically arranged on both sides of the slide rail 2. Each rail plate 6 has a crease. The bottom surface on both sides of the crease is provided with a power arm travel rail. The power arm travel rail is used to connect the power arm. The pneumatic power arm is used to drive the drive device to align with the top nut of the fine adjustment claw. The multi-functional auxiliary slot plate is fixed on both sides of the top structure of the fine adjustment claw. After the alignment is completed, the pneumatic power arm locking button is turned on.
[0043] In this embodiment, the crease is W-shaped.
[0044] The inner sides of the two connecting rods 11 are also provided with a second groove, and the second groove matches the end of the rail plate 6. The end of the rail plate 6 presses the second irregular buffer sleeve into the second groove, and the vibration between the rail plate 6 and the connecting rod 11 is relieved by the second irregular buffer sleeve.
[0045] Two trays 7 are fixedly connected to the end of the top surface of the frame 1. The trays 7 are used to support the air compressor 8. The air compressor 8 squeezes the third irregularly shaped buffer sleeve into the tray 7. The vibration between the tray 7 and the air compressor 8 is relieved by the third irregularly shaped buffer sleeve.
[0046] In this embodiment, the tray 7 supports four small-power air compressors 8. The traditional approach is to use a single high-power air compressor to control the operation of four auxiliary arms, which is not conducive to vibration reduction of the control box. Instead of a single high-power air compressor, four small-power air compressors 8 are used. The four small-power air compressors 8 are connected to the four auxiliary arms through air guide pipes, which can effectively decompose the vibration of the control box.
[0047] The bottom of the four legs of the frame 1 are provided with drive wheels, and the outer side wall of each leg of the frame 1 is provided with an auxiliary roller assembly 9.
[0048] In this embodiment, each auxiliary roller assembly 9 includes: an auxiliary rod, two inclined support rods, and two rollers. The auxiliary rod is horizontally fixed to the outer wall of the support leg, and each end of the auxiliary rod is connected to an inclined support rod. Each inclined support rod extends radially, and a roller is rotatably connected to the extended end of each inclined support rod. The rollers are used to engage with the anti-collision wall, which helps to improve the stability of the frame 1.
[0049] A vibration reduction method for reducing the feedback error of track slab fine-tuning detection includes the following steps:
[0050] S1. The frame 1 travels through the drive wheels and engages with the anti-collision wall through the auxiliary roller assembly 9, and the frame 1 travels to the working area.
[0051] S2. The sensor support frame 3 slides on the slide rail 2, moving the elevation laser displacement monitoring sensor 4 and the lateral laser displacement monitoring sensor 5 to the detection area.
[0052] Among them, the elevation laser displacement monitoring sensor 4 detects the track slab laying parameters on the Z-axis, and the lateral laser displacement monitoring sensor 5 detects the track slab laying parameters on the X-axis.
[0053] S3. Adjusting the lengths of the first telescopic component 32 and the second telescopic component 34, and adjusting the heights of the elevation laser displacement monitoring sensor 4 and the lateral laser displacement monitoring sensor 5, can achieve multi-dimensional stable detection feedback.
[0054] Example 2
[0055] Reference Figure 6 As shown, based on Embodiment 1, each auxiliary roller assembly 9 includes: an electrically controlled telescopic rod and a roller. The base end of the electrically controlled telescopic rod is fixedly connected to the outer wall of the support leg, and the moving end of the electrically controlled telescopic rod is rotatably connected to the roller. The telescopic length of the electrically controlled telescopic rod can meet the requirements of different distances between the anti-collision wall and the frame 1, and the electrically controlled telescopic rod can be locked to ensure that the length of the electrically controlled telescopic rod remains unchanged, providing stable anti-collision support.
[0056] The above description is merely a preferred embodiment of the present invention and does not constitute any limitation on the technical scope of the present invention. Therefore, any minor modifications, equivalent changes, and alterations made to the above embodiments based on the technical essence of the present invention shall still fall within the scope of the technical solution of the present invention.
