[0002] The ballast bed is an important component of railway tracks, primarily serving to support sleepers, distribute train loads, and maintain track geometry stability. Its smoothness directly affects the safety, stability, and comfort of train operation. With the development of railway transportation towards high speed and heavy load, higher requirements are placed on the accuracy and efficiency of ballast bed smoothness testing.

[0003] In existing methods for detecting track bed flatness, traditional manual inspection relies on tools such as straightedges, levels, or total stations. This not only involves high labor intensity and low inspection efficiency, but also makes the inspection results susceptible to the operator's experience and environmental factors. Furthermore, debris such as gravel and dust scattered on the track bed surface can easily obstruct the laser detection path, leading to distorted inspection data.

[0004] Therefore, it is necessary to invent a track bed flatness detection device to solve the above problems. Utility Model Content

[0021] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0022] This utility model provides, for example Figure 1-4 The track bed leveling detection device shown includes a mounting frame 1. A bidirectional threaded rod 2 is rotatably connected between the two sides of the inner wall of the mounting frame 1. Threaded seats 3 are threadedly connected to both sides of the surface of the bidirectional threaded rod 2. Movable seats 4 are fixedly installed at the front and rear ends of one side of the threaded seats 3. One side of the movable seats 4 passes through the mounting frame 1 and extends to the outside of the mounting frame 1. A track wheel 5 is fixedly installed on one side of the bottom of the movable seats 4 through a stabilizing seat. A mounting plate 6 is fixedly installed at the bottom of the mounting frame 1. LiDAR 7 is fixedly installed on both sides of the bottom of the mounting plate 6. A telescopic pushing assembly 8 is fixedly installed at the top of the mounting frame 1. A cleaning mechanism 9 is provided on the rear side of the mounting frame 1.

[0023] The top of the mounting frame 1 is equipped with a data transmission module that works with the lidar 7. It is used to receive signals transmitted by the lidar 7 and transmit the signals to external terminals. Both the lidar 7 and the data transmission module use existing technologies.

[0024] The telescopic push assembly 8 includes a fixed cylinder 81, which is fixedly connected to the top of the mounting frame 1 via a connecting seat. A sliding disk 82 is slidably connected inside the fixed cylinder 81, and a push handle 83 is fixedly installed on one side of the sliding disk 82. One end of the push handle 83 passes through the fixed cylinder 81 and extends to the outside of the fixed cylinder 81.

[0025] A support base 84 is fixedly connected to the bottom of the other side of the sliding disk 82, and a sliding seat 85 is slidably connected to the top of the other side of the sliding disk 82. A spring 86 is fixedly installed between the support base 84 and the opposite side of the sliding seat 85. A locking rod 87 is fixedly installed on the top of the sliding seat 85. The top end of the locking rod 87 passes through the fixed cylinder 81 and extends to the outside of the fixed cylinder 81. A plurality of locking grooves 88 are provided on the fixed cylinder 81 to cooperate with the locking rod 87.

[0026] When adjusting the height of the push handle 83, press the top of the locking rod 87. The locking rod 87 drives the sliding seat 85 to slide down along the sliding plate 82 and compress the spring 86. The bottom of the locking rod 87 disengages from the slot on the fixed cylinder 81. Push the push handle 83 to slide inside the fixed cylinder 81. The sliding plate 82 moves synchronously with the push handle 83 until the extension length of the push handle 83 reaches a comfortable operating position. Release the locking rod 87. The spring 86 returns to its original position and pushes the sliding seat 85 to move upward. The top of the locking rod 87 engages in the corresponding slot 88, thus fixing the length of the push handle 83.

[0027] The cleaning mechanism 9 includes two supports 91. The tops of the two supports 91 are fixedly connected to the two sides of the bottom rear end of the mounting frame 1, respectively. A cleaning roller 92 is rotatably connected to the opposite side of the two supports 91. A drive motor 93 for driving the cleaning roller 92 to rotate is fixedly installed on one of the supports 91.

[0028] The surface of the cleaning roller 92 is provided with nylon bristles;

[0029] The drive motor 93 drives the cleaning roller 92 to rotate between the two supports 91 to clean larger debris on the track bed surface;

[0030] A blower 94 is fixedly installed at the rear end of the top of the mounting frame 1. A connecting pipe 95 is fixedly installed on the rear side of the mounting frame 1. Multiple air blowing pipes 96 are connected to the surface of the connecting pipe 95. The connecting pipe 95 is connected to the output end of the blower 94 through the pipe.

[0031] The airflow generated by the fan 94 is delivered to the connecting pipe 95 through the pipeline, and then blown evenly onto the track bed surface through multiple air blowing pipes 96 to remove fine dust and residual debris, and to prevent debris from obstructing the laser detection path;

[0032] A rotating rod 10 runs through the front of the mounting frame 1. A rotating disk 11 is fixedly installed at one end of the rotating rod 10. A bevel gear 12 is fixedly installed at the other end of the rotating rod 10 and on the surface of the bidirectional threaded rod 2. The two bevel gears 12 mesh with each other.

[0033] Before inspection, the track wheels 5 are adjusted according to the track gauge of the track bed to be inspected. The operator rotates the rotating disk 11, which drives the rotating rod 10 to rotate. Through two meshing bevel gears 12, the bidirectional threaded rod 2 is driven to rotate within the mounting frame 1. The threaded seats 3 on both sides of the surface of the bidirectional threaded rod 2 move in opposite directions along the axial direction of the threaded rod, and then drive the track wheels 5 to move synchronously through the moving seat 4 until the track wheels 5 on both sides are adapted to the track gauge of the track bed. After the adjustment is completed, the rotating disk 11 is stopped.

[0034] The working principle of this practical application is as follows:

[0035] Before inspection, the track wheels 5 are adjusted according to the track gauge of the track bed to be inspected. The operator rotates the rotating disk 11, which drives the rotating rod 10 to rotate. Through two meshing bevel gears 12, the bidirectional threaded rod 2 is driven to rotate within the mounting frame 1. The threaded seats 3 on both sides of the surface of the bidirectional threaded rod 2 move in opposite directions along the axial direction of the threaded rod, and then drive the track wheels 5 to move synchronously through the moving seat 4 until the track wheels 5 on both sides are adapted to the track gauge of the track bed. After the adjustment is completed, the rotating disk 11 is stopped.

[0036] Pressing the top of the lever 87 causes the sliding seat 85 to slide downwards along the sliding plate 82 and compress the spring 86. The bottom of the lever 87 disengages from the slot on the fixed cylinder 81. Pushing the push handle 83 slides inside the fixed cylinder 81, the sliding plate 82 moves synchronously with the push handle 83 until the push handle 83 extends to a comfortable operating position. Releasing the lever 87 causes the spring 86 to reset and push the sliding seat 85 upwards. The top of the lever 87 engages in the corresponding slot 88, thus fixing the length of the push handle 83.

[0037] During the inspection, the drive motor 93 and the fan 94 are started. The drive motor 93 drives the cleaning roller 92 to rotate between the two supports 91 to clean larger debris on the track bed surface. The airflow generated by the fan 94 is transported to the connecting pipe 95 through the pipeline, and then blown evenly onto the track bed surface through multiple air blowing pipes 96 to remove fine dust and residual debris, and to prevent debris from obstructing the laser detection path. The operator holds the push handle 83 and pushes the device to move smoothly along the track bed through the track wheels 5. The two laser radars 7 at the bottom of the mounting plate 6 simultaneously collect distance data at different positions on the track bed surface, and provide real-time feedback on the track bed flatness, thus completing the inspection operation.
