[0039] To make the objectives, technical solutions, and advantages of the present invention more clear, the technical solutions of the present invention will be clearly and completely described below in conjunction with the accompanying drawings. Obviously, the embodiments described are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts shall fall within the scope of protection of the present invention.

[0040] The following combination Figures 1 to 5 It should be understood that the following description is merely an illustrative embodiment of the present invention and does not constitute any limitation to the present invention.

[0041] As an embodiment of the present invention, the present invention provides a track-based intelligent level rod fixing device, including a level rod 1, a device body 2 and a walking mechanism 3.

[0042] The device body 2 is horizontally positioned, and the leveling staff 1 is mounted perpendicular to the device body 2. Both the device body 2 and the leveling staff 1 are mounted on a traveling mechanism 3, which is closely attached to and moves along the track. The traveling mechanism 3 includes a carrier 31, a drive component 32, a guide component 33, and a brake component 34. The carrier 31 supports the leveling staff 1 and the device body 2, the drive component 32 controls the movement of the traveling mechanism 3, the guide component 33 controls the direction of the drive component 32, and the brake component 34 controls the deceleration and stopping of the drive component 32.

[0043] Moreover, the level rod 1 is a prior art, and its specific structural features and connection relationships are known to those skilled in the art and will not be described in detail here.

[0044] It can be understood that in the existing technology, workers are required to use a level to measure track elevation on a track section. The location of the test points on the section varies with the measurement distance. Therefore, after measuring the elevation of one point, the worker moves with the level to the next test point. This results in high labor intensity and low measurement efficiency.

[0045] In this embodiment, this moving process is replaced by a track-based intelligent level fixture. By setting up the equipment body 2 and the walking mechanism 3, the level 1 and the equipment body 2 are mounted on the walking mechanism 3. The walking mechanism 3 drives the equipment body 2 and the level 1 to move synchronously. It can not only replace manual movement, but also accurately control the travel distance and automatically move the level 1 for measurement, thereby effectively saving labor costs, reducing the labor intensity of staff, and improving work efficiency.

[0046] In this embodiment, specifically, Figures 1 to 3 As shown, the carrier 31 functions as a crossbeam. Its length is equal to the distance between the two rails, connecting the running mechanisms 3 at both ends. A chute 4 is provided along the carrier 31's length. A slider 5 is slidably connected within the chute 4. A mounting bracket 9 for the leveling rod 1 is fixedly connected to the slider 5. The leveling rod 1 is fixed to the mounting bracket 9 via fasteners 10. The slider 5 can slide freely within the chute 4, allowing the leveling rod 1 to slide back and forth between the two rails to measure multiple points on the same cross-section.

[0047] Wherein, I-shaped connectors may be vertically provided at both ends of the carrier 31 , and the driving component 32 , the guide component 33 and the braking component 34 may be connected via the I-shaped connectors.

[0048] In addition, the fixing frame 9 is provided with a through-hole, and the level rod 1 is perpendicular to the fixing frame 9 and accommodated inside the fixing frame 9; the shape and structure of the fixing frame 9 is determined according to the shape of the level rod 1, such as a square structure. The fastener 10 can be a bolt.

[0049] In this embodiment, the driving component 32 specifically includes a driving wheel 321 and a driver 322. The driving wheel 321 is a tire fixedly mounted on both ends of the carrier 31 via a driving shield 323. The driving wheel 321 contacts the top surface of the track. The drive shaft of the driving wheel 321 is connected to the output shaft of the driver 322, which is a reduction motor. When the driver 322 is activated, it drives the drive shaft to rotate, thereby causing the driving wheel 321 to move forward.

[0050] The drive shield 323 is fixedly connected to the I-shaped connector, which can be connected by bolts or welding. The drive shield 323 and the drive wheel 321 are mounted via a bearing. That is, a mounting hole is provided on the drive shield 323, and the drive shaft of the drive wheel 321 is mounted in the mounting hole via a bearing.

[0051] In this embodiment, specifically, the guide component 33 includes a guide plate 331 and a guide wheel 332 symmetrically arranged on both sides of the driving wheel 321, wherein the guide plate 331 is fixedly connected to the driving protective cover 323, and mounting lugs are integrally provided on both sides of the driving protective cover 323. The guide plate 331 can be fixed to the mounting lugs by screws or bolts. The other end of the guide plate 331 is connected to the guide shaft 333, and the guide wheel 332 is connected to the guide shaft 333 through a bearing.

[0052] The guide shaft 333 is perpendicular to the guide plate 331 and parallel to the side of the track. The guide wheel 332 can be a rubber wheel. When the driving wheel 321 runs on the track, the guide wheel 332 abuts against the two side surfaces of the track and slides in parallel on the two sides to stabilize the operation of the driving wheel 321.

[0053] Furthermore, the center points of the drive wheel 321 and the two guide wheels 332 are connected to form an equilateral triangle. As the drive wheel 321 moves along the track, the two guide wheels 332 not only guide it but also serve as auxiliary wheels, ensuring more stable operation of the drive wheel 321. This ensures the stability of the equipment during measurement. Furthermore, the left and right guide wheels 332 clamp onto the middle vertical plate of the track, ensuring smooth and slip-free movement of the fixed equipment on slopes.

[0054] In this embodiment, specifically, the brake component 34 includes a brake plate 341, a brake clamp 342, a brake rod 343 and a brake controller 344. The brake clamp 342 is fixedly connected to the brake rod 343, and the brake controller 344 controls the brake rod 343 to move vertically upward or downward.

[0055] Among them, the brake plate 341 is fixed to one end of the drive protective cover 323 by bolts or welding, and the cross-sectional shape of the brake plate 341 is triangular. The brake controller 344 is located above the brake plate 341, and the brake rod 343 is vertically connected to the bottom of the brake controller 344. The central axis of the brake rod 343 coincides with the center line of the brake plate 341. The structure is relatively stable, so that the braking effect of the drive component 32 is good.

[0056] Among them, Figure 3 As shown, brake clamp 342 comprises two symmetrically arranged brake members, located on either side of brake lever 343. These brake members are connected to brake lever 343 via connecting blocks 345, which are fixedly attached to the latter. As brake lever 343 moves up and down, connecting blocks 345 move synchronously, driving the brake members toward or away from each other. One end of the brake member is hinged to connecting block 345, and the other end is pivotally connected to brake plate 341 via a hinge axis. Brake plate 341 is positioned parallel to the brake member.

[0057] Furthermore, brake controller 344 is a pneumatic cylinder or worm-gear structure. In the case of a pneumatic cylinder, the cylinder's output end is connected to brake lever 343, driving brake lever 343 to move vertically. In the case of a worm-gear structure, one end of brake lever 343 is a worm gear that meshes with a turbine. The turbine is driven by a motor, driving the worm gear to move vertically.

[0058] like Figure 3 As shown, the brake member is a special-shaped member with a tentacles at the end, and anti-slip pads are provided on the tentacles. When braking is required, the brake controller 344 is activated, driving the brake rod 343 to move vertically upward, and driving one end of the brake member to move with the upward movement of the brake rod 343. At this time, the other ends of the brake members approach each other, and the tentacles approach the track until they contact the track sidewalls and clamp onto both sides of the track, forcing the drive component 32 to stop moving, thereby achieving accurate positioning and improving measurement results.

[0059] As an optional embodiment of the present invention, in order to make the movement of the traveling mechanism 3 along the track more stable, the width of the tire is close to the width of the track, thereby increasing the contact area between the tire and the track and making the operation more stable.

[0060] In this embodiment, the device body 2 includes a housing made of a lightweight material, such as aluminum alloy. A display screen 6 is provided on the housing to display information such as distance traveled and battery charge. This display screen 6 is a touchscreen, allowing touch control of the stationary device. A start / stop button is provided on the housing, located to one side of the display screen 6.

[0061] In addition, a battery box 7 is provided on the housing. The battery box 7 includes a battery mounting slot and a battery cover. The battery is installed in the battery mounting slot and is closed by the battery cover. During use, the battery can power the entire fixed device. At the same time, the battery can be removed and charged. Therefore, the battery can be selected as a storage battery.

[0062] Furthermore, a PLC controller is installed in the housing to control and coordinate the operation of various components in the fixed equipment. The PLC controller includes a main controller module, motor drive module, LCD module, keyboard module, distance measurement module, Bluetooth communication module, power supply module, etc.

[0063] A distance detector is attached to the device body 2 and electrically connected to the PLC controller and battery. It detects the distance traveled by the device body 2 on the track and provides feedback to the PLC controller. The PLC controller collects and analyzes the information and then provides feedback to the motor driver 322, thereby controlling the driver 322 to stop and start the drive wheel 321.

[0064] As an optional embodiment of the present invention, the movement and stopping of the fixed device are controlled by a remote control. The remote control includes a transmitter module, which transfers the encoder's command signal onto a radio frequency signal and radiates it into the air. A receiver is mounted within the housing, which includes a receiving module. This module receives the carrier frequency signal containing the command signal, separates the command signal from the high-frequency signal, and converts it back into a command signal, which is then sent to a decoder. The decoder's output controls the execution component, specifically the stopping of the actuator 322, which in turn controls the starting and stopping of the drive wheel 321.

[0065] As an optional embodiment of the present invention, the movement and stopping of the fixed device can be controlled via a mobile phone. The client is a Bluetooth mobile phone, and the server is a Bluetooth communication module within the PLC controller. The mobile phone sends a Bluetooth signal to the Bluetooth communication module via Bluetooth. The PLC controller receives and processes the signal and provides feedback to the driver 322, thereby controlling the stopping of the driver 322 and further controlling the starting or stopping of the drive wheel 321.

[0066] As an optional embodiment of the present invention, the sliding of the level rod within the chute 4 can be controlled automatically. Specifically, a lead screw (not shown) is provided along the direction of the chute 4, so that the slider 5 is synchronously connected to the lead screw and the slider 5. One end of the lead screw is connected to a motor, which is electrically connected to a PLC controller. Therefore, a command is sent to the PLC controller via remote control or mobile phone control. The PLC controller drives the motor to start or stop, which drives the lead screw to drive the slider 5 to move within the chute 4, thereby causing the level rod fixed to the slider 5 to move back and forth along the direction of the chute 4.

[0067] As an optional embodiment of the present invention, an illumination structure 8 is provided on the housing at equal intervals along its length. This illumination structure 8 comprises multiple LED lights embedded in the housing surface. These LED lights are connected in parallel, so replacing one lamp does not affect the lighting of the others. The LED lights are electrically connected to and controlled by a PLC controller. This eliminates the need for additional personnel to hold lights for illumination during leveling, addressing the current issues of wasted human resources and low efficiency in track operations.

[0068] like Figure 5 As shown, during use of the present invention, the two driving wheels 321 are placed on the two tracks respectively, so that the driving wheel 321 contacts the top surface of the track, and the two guide wheels 332 on both sides of the driving wheel 321 are respectively in contact with the side surfaces of the track. At this time, the carrier 31 supports the level rod 1 and the equipment body 2 and is erected across the two tracks, so that the fixed equipment can move freely forward and backward on the straight track.

[0069] Then, a fixed distance is set using display screen 6, and the start button below display screen 6 is pressed to start the fixed device from moving. After moving the fixed distance, the fixed device automatically stops. Level rod 1 performs track elevation measurement; it can also be controlled to move between two tracks to measure the elevation of different test points on the same section between the two tracks.

[0070] Alternatively, the start button is pressed at the starting position, and when a specific position is reached, the stop button is pressed to stop the fixed device, and the distance traveled can be displayed on the display screen 6. When it is necessary to stop, the brake controller 344 is activated, driving the brake rod 343 to move vertically upward, and at the same time driving one end of the brake member to move with the upward movement of the brake rod 343. At this time, the other ends of the brake members approach each other, causing the feelers to approach the track until they contact the side walls of the track and clamp on both sides of the track, forcing the driving component 32 to stop moving, thereby achieving accurate positioning.

[0071] The track-based level rod fixing device provided by the present invention can accurately control the travel distance during the measurement process and can automatically move the level rod 1 for measurement, thereby effectively saving labor costs, reducing the labor intensity of workers, having high operating efficiency, low requirements for operators, and simple operation.

[0072] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the various embodiments of the present invention.
