Description

Technical Field

[0001] The present invention relates to the technical field of track gauge measurement, and particularly to an intelligent remote-controlled gauge laser detection vehicle. Background Art

[0002] The commonly used methods for measuring track gauge mainly fall into two major categories: contact measurement and non-contact measurement. The contact track gauge measurement method uses a linear displacement sensor to measure the track gauge. During the detection process, a mechanical structure ensures that the sensor is in contact with the track gauge point to be measured at all times. Although the measurement result is relatively accurate at low speeds, the measurement efficiency is low. In addition, since the sensor needs to contact the track during the measurement process, when the detection speed needs to be increased, it is easy to cause wear of the sensor, resulting in a decrease in measurement accuracy. There is also a possibility of damaging the rail and creating potential safety hazards. The non-contact track gauge measurement method uses a camera mechanism to continuously capture images of the inner cross-section of the track gauge, and reconstructs the inner side curve of the track through image reconstruction to calculate the track gauge value. This measurement method has high measurement accuracy and is not affected by the detection speed, but it is easily interfered by light, has strict requirements for the use environment, and the scope of use is limited. In addition, its structure is complex and the cost is high.

[0003] Chinese Patent CN109338833B discloses a gauge detection device for high-speed railway tracks, including a rectangular plate body and two steel rails. On the front and rear sides of the left end and the front and rear sides of the right end of the plate body, horizontal axes are symmetrically and fixedly installed. The four horizontal axes are parallel to each other, and the two horizontal axes corresponding to the left and right ends of the plate body are coaxial. At the middle position of the horizontal axis, a rubber roller is movably installed through a bearing. At both the left and right ends of the horizontal axis, collar rings are sleeved through linear bearings. An annular cavity is provided inside the collar ring. First through holes are opened at both the top and bottom of the collar ring, and one end of a vertical pipe is fixedly connected to the outer end of each first through hole. A horizontal pipe is provided inside the other end of each vertical pipe, and the outer end of the horizontal pipe is fixedly connected to the other end of the corresponding vertical pipe. The inner ends of the two horizontal pipes located on the upper part of the same horizontal axis are sleeved with a sleeve. A bearing is used for the movable connection between the end of the sleeve and the inner end of the corresponding horizontal pipe. A rotating shaft is provided inside the sleeve, and the rotating shaft is coaxial with the corresponding sleeve. Both ends of the rotating shaft are located inside the corresponding horizontal pipe. A spiral blade is fixedly sleeved on the outer circumference of the part of the rotating shaft located inside the horizontal pipe. A connecting frame is fixedly connected between the middle of the rotating shaft and the inner wall of the corresponding sleeve. First rubber wheels are fixedly sleeved at both ends of the sleeve, and the first rubber wheels are in contact and cooperation with the corresponding rubber rollers. Inside the inner ends of the lower horizontal pipes, piston columns are fitted and installed. Long strip guide grooves are opened at the positions corresponding to the piston columns on the top of the horizontal pipes. The long strip guide grooves are opened along the length direction of the horizontal pipes. First sliders are arranged in the long strip guide grooves in a matching manner. The inner end of the first slider is fixedly connected to the top of the corresponding piston column. Vertical columns are fixedly installed on the top of the first sliders. Second rubber wheels are installed at the upper ends of the columns through bearings. The second rubber wheels are in contact and cooperation with one side of the upper part of the corresponding steel rail. Vertical rods are fixedly installed at the upper ends of the upper vertical pipes. A connecting block is provided in the middle between the upper ends of the two corresponding vertical rods. Fixed frames are fixedly connected between the left and right ends of the connecting block and the upper ends of the vertical rods. An annular plate is fixedly sleeved in the middle of the rotating shaft, and the outer ring of the annular plate is fixedly connected to the inner wall of the corresponding sleeve. The annular plate divides the inside of the corresponding sleeve into two isolated cavities on the left and right. Link rods are fixedly connected between the upper ends of the two connecting blocks on the same side of the plate body. A laser rangefinder is installed in the middle of the upper part of the link rod on the left side, and a reflector is fixedly installed in the middle of the upper part of the link rod on the right side.

[0004] Although the above solution simplifies the structure, when the inspection vehicle moves along the extending direction of the track, the gauge of the track may change. The above solution realizes the positioning of the detection center by clamping a single track. However, during the use of the track, wear may occur or it may be adhered with dirt, which will cause the deviation of the detection center position, and further lead to the deviation of the final detection result. Moreover, there is no corresponding device for isolating external light on the detection path of the laser rangefinder in the above solution, so it is still impossible to ensure the influence of external light on the laser rangefinder during detection. Summary of the Invention

[0017] In summary, the present application has the following beneficial technical effects:

[0018] 1. During measurement, the base moves along the extension direction of the guide rail, and the near-rail measurement mechanism measures the side wall of the guide rail during the movement of the base. The two near-rail measurement mechanisms respectively measure distances a1 and a2. Even if, during the measurement process, the near-rail measurement mechanism becomes disconnected due to the deformation of the track, the first laser rangefinder in the near-rail measurement mechanism can still measure the track. Since the first laser rangefinder is relatively close to the side wall of the track, the laser is less affected by external light. In this way, the accuracy of a1 and a2 after measurement can be ensured. When measuring the distance between the two near-rail measurement mechanisms, the laser path emitted by the second laser rangefinder is completely wrapped by the passage light-shielding tube, so that the second laser rangefinder is not affected by external light at all. The distance b between the two near-rail measurement mechanisms can be measured by the second laser rangefinder. Finally, by summing a1, a2, and b, the gauge of the track can be calculated, improving the measurement accuracy and reducing the influence of external light on laser detection.

[0019] 2. The pressing assembly provides a pressing force in the width direction of the base for the two near-rail measuring mechanisms. The near-rail measuring mechanisms move along the width direction of the base under the pressing of the pressing assembly. The track has a reaction force on the pressing assembly. The adaptive assembly is arranged inside the base. The pressing assembly drives the base to displace under the action of the reaction force. After the displacement, the distances from the base to the two near-rail measuring mechanisms are equal. By setting the balancing mechanism, the base can always be located on the center line between the two near-rail measuring mechanisms, so that the wear amounts of the two near-rail measuring mechanisms are basically the same during the movement of the base.

[0020] 3. During the movement of the base, the second laser rangefinder monitors the distance to the cassette in the near-rail measuring mechanism on the opposite side through the second measuring hole. In this way, the distance between the two near-rail measuring mechanisms can be measured. Since the second measuring hole and the passage light-shielding tube are coaxially arranged, the laser emitted by the second laser rangefinder will completely penetrate the passage light-shielding tube, and the external light is isolated by the passage light-shielding tube, which will not affect the laser emitted by the second laser rangefinder, improving the accuracy of the value b.

[0021] 4. The tight-fitting part is fixedly arranged on one side of the cassette close to the side wall of the track. When the laser detection vehicle runs, the tight-fitting part is electrified, and the tight-fitting part has an adsorption force on the track, so that the tire body in the contact assembly can better contact with the track, and it is not easy to break away even during high-speed movement.

Detailed implementation manners

[0035] Next, the technical solutions of the present invention will be clearly and completely described in conjunction with the accompanying drawings. Obviously, the described embodiments are part of the embodiments of the present invention, rather than all of them. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0036] Refer to Figures 1 to 3, An intelligent remote-controlled gauge laser detection vehicle moves along the extending direction of the track 4, including a base 1 and four rollers 5 symmetrically arranged on both sides of the base 1. A signal receiver is arranged inside the base 1 for receiving remote control signals. The staff can control the movement of the base 1 through remote control. An annular groove is formed on the peripheral wall of the roller 5. When placing, the annular groove on the peripheral wall of the roller 5 is placed on the track 4, so that the roller 5 can be clamped on the track 4. When the base 1 moves along the extending direction of the track 4, the roller 5 is not likely to derail; the laser detection vehicle further includes a balance mechanism 6, a spacing measurement mechanism 3 and two symmetrically arranged near-rail measurement mechanisms 2. The top of the balance mechanism 6 is slidably connected to the base 1, and the two ends of the bottom of the balance mechanism 6 are respectively rotatably connected to the two near-rail measurement mechanisms 2; the two near-rail measurement mechanisms 2 are respectively abutted against the inner wall of the track 4, and the near-rail measurement mechanism 2 is used to measure the distance between it and the side wall of the track 4; in the width direction of the base 1, there is a gap between the two near-rail measurement mechanisms 2, and the spacing measurement mechanism 3 is horizontally arranged in the gap, and the two ends of the spacing measurement mechanism 3 are respectively fixedly connected to the two near-rail measurement mechanisms 2, and the spacing measurement mechanism 3 is used to measure the distance between the two near-rail measurement mechanisms 2.

[0037] In this embodiment, during measurement, the base 1 moves along the extending direction of the guide rail. The near-rail measurement mechanism 2 performs laser ranging on the side wall of the guide rail during the movement of the base 1. The two near-rail measurement mechanisms 2 respectively measure distances a1 and a2. Even during the measurement process, if the near-rail measurement mechanism 2 gets out of contact due to the deformation of the track 4, since the near-rail measurement mechanism 2 is close to the side wall of the track 4, the laser is less affected by external light, that is, the measured a1 and a2 are more accurate. The spacing measurement mechanism 3 arranged between the two near-rail measurement mechanisms 2 measures the distance between the two near-rail measurement mechanisms 2, which is recorded as distance b. Finally, the sum of a1, a2 and b is calculated to obtain the gauge of the track 4, improving the measurement accuracy and reducing the influence of external light on laser detection.

[0038] In one of the embodiments, referring to Figure 4 and Figure 7 , the balance mechanism 6 includes a pressing component 61 and an adaptive component 62. The pressing component 61 has an isosceles triangle structure. The top of the pressing component 61 slides through the base 1 along the height direction of the base 1. The two ends of the bottom of the pressing component 61 are respectively hinged to the two near-rail measurement mechanisms 2. The pressing component 61 provides a pressure on the two near-rail measurement mechanisms 2 along the width direction of the base 1; the adaptive component 62 is horizontally arranged inside the base 1. The adaptive component 62 is slidably connected to the base 1. The base 1 reciprocally slides along the direction of the adaptive component 62. In the balanced state, the distances between the base 1 and the two near-rail measurement mechanisms 2 are equal.

[0039] In this embodiment, the pressing assembly 61 provides a pressing force in the width direction of the base 1 to the two near-rail measuring mechanisms 2. The near-rail measuring mechanisms 2 move along the width direction of the base 1 under the pressing of the pressing assembly 61, and the rail 4 has a reaction force on the pressing assembly 61. The adaptive assembly 62 is arranged inside the base 1. The pressing assembly 61 drives the base 1 to displace under the action of the reaction force. The distances from the moved base 1 to the two near-rail measuring mechanisms 2 are equal. By setting the balancing mechanism 6, the base 1 can always be located on the center line between the two near-rail measuring mechanisms 2, so that the wear amounts of the two near-rail measuring mechanisms 2 are basically the same during the movement of the base 1.

[0040] In one embodiment, referring to Figure 4 and Figure 5 , the pressing assembly 61 includes a pressing rod 611, a pressing block 612 and two connecting rods 613. The pressing rod 611 slides through the base 1 in the height direction of the base 1. The pressing block 612 is fixedly connected to the top end of the pressing rod 611. The two connecting rods 613 are symmetrically arranged at the bottom of the pressing rod 611. One end of the connecting rod 613 is fixedly connected to the bottom end of the pressing rod 611, and the end of the connecting rod 613 away from the pressing rod 611 is hinged to the near-rail measuring mechanism 2. A first guide frame 614 is fixedly connected to the top of the near-rail measuring mechanism 2, and a second guide frame 615 is fixedly connected to the bottom of the base 1. A guide groove is formed in the second guide frame 615 along the width direction of the base 1. One end of the first guide frame 614 away from the near-rail measuring mechanism 2 is slidably connected to the guide groove.

[0041] In this embodiment, the near-rail measuring mechanism 2 includes a dark box 21. The ends of the two connecting rods 613 away from the pressing rod 611 are hinged to the upper part of the dark box 21 in the two near-rail measuring mechanisms 2. Under the pressing of the pressing assembly 61, the two near-rail measuring mechanisms 2 are always in contact with the side wall of the rail 4. The force provided by the pressing block 612 to the pressing rod 611 is vertically downward. When the force is transmitted to the connecting rod 613, the direction of the force is inclined. The connecting rod 613 transmits its horizontal force to the near-rail measuring mechanism 2. The first guide frame 614 is fixedly arranged on the upper part of the dark box 21, and the second guide frame 615 is fixedly arranged at the bottom of the base 1. The first guide frame 614 is slidably matched with the guide groove. In this way, when the connecting rod 613 pushes the two near-rail measuring mechanisms 2 to move, the two near-rail measuring mechanisms 2 can only move along the width direction of the base 1.

[0042] In one embodiment, referring to Figure 10The adaptive component 62 includes four adaptive grooves 621, four sliding rods 622 and an exhaust pipe 623, and a switch valve 624 is fixedly arranged on the exhaust pipe 623; the adaptive grooves 621 are opened inside the base 1 along the width direction of the base 1, and the sliding rods 622 correspond to the adaptive grooves 621 one by one. The sliding rods 622 are respectively slidably arranged in the adaptive grooves 621 along the extension direction of the adaptive grooves 621; the two ends of the sliding rods 622 are respectively fixedly connected to the mounting plates of the side walls of the roller 5, and the exhaust pipe 623 is arranged on the surface of the base 1, and the exhaust pipe 623 and the adaptive grooves 621 are connected to each other.

[0043] In this embodiment, when performing detection, the base 1 moves along the extension direction of the track 4. When the extension direction of one side of the track 4 that the base 1 moves through remains unchanged, and the other side extends slightly outward, that is, the two tracks 4 are no longer in a parallel state due to wear and other reasons, the pressing component 61 always provides pressing force to the two near-track measuring mechanisms 2. In this way, when the two tracks 4 are not parallel, the positions of the two near-track measuring mechanisms will change with the extension direction of the track 4, that is, the near-track measuring mechanism 2 on the side of the track 4 whose extension direction remains unchanged will not be displaced, while the near-track measuring mechanism 2 on the side of the track 4 whose extension direction extends slightly outward will be displaced. Since the pressing force of the two near-track measuring mechanisms 2 is provided by the pressing component 61, and the pressing component 61 is always located at the central axis position of the two near-track measuring mechanisms 2, when one of the near-track measuring mechanisms 2 moves along the base 1, the pressing force of the two near-track measuring mechanisms 2 is provided by the pressing component 61, and the pressing component 61 is always located at the central axis position of the two near-track measuring mechanisms 2. 1 is displaced in the width direction, the pressing component 61 will also be displaced in the width direction of the base 1. Since the pressing component 61 and the base 1 do not have relative displacement in the horizontal direction, the pressing component 61 will also drive the base 1 to move when it moves. At this time, the adaptive groove 621 and the sliding rod 622 slide relative to each other, and the air in the adaptive groove 621 communicates with the outside world through the exhaust pipe 623. A switch valve 624 is provided on the exhaust pipe 623. When the laser detection vehicle is not in use, the switch valve 624 is in a closed state, and when the laser detection vehicle is in use, the switch valve 624 is opened, so that the air in the adaptive groove 621 will communicate with the outside world, thereby enabling the base 1 to adaptively slide to the center of the two near-track measuring mechanisms 2, thereby achieving that the wear amount of the two contact components 22 in the two near-track measuring mechanisms 2 remains basically consistent.

[0044] In one embodiment, referring to Figure 5 , Figure 6 and Figure 9, the near-rail measuring mechanism 2 includes a dark box 21, a contact assembly 22, and a first laser rangefinder 23. The dark box 21 is fixedly arranged at the bottom of the balance mechanism 6. The dark box 21 is located on one side of the inner wall of the track 4. A first measurement hole is opened on the side of the dark box 21 close to the track 4; the contact assembly 22 is of an annular structure. The contact assembly 22 is rotatably sleeved on the outer wall of the dark box 21, and the contact assembly 22 abuts against the side wall of the track 4; the first laser rangefinder 23 is fixedly arranged inside the dark box 21. The laser emitting end of the first laser rangefinder 23 faces the first measurement hole, and the first laser rangefinder 23 measures the side wall of the track 4 through the first measurement hole.

[0045] In this embodiment, the contact assembly 22 includes a rotating ring 221 and a tire body 222. The dark box 21 is of a cylindrical shell structure. The rotating ring 221 is rotatably arranged around the axis of the dark box 21 on the periphery of the dark box 21. The tire body 222 is of an annular structure. The tire body 222 is sleeved on the periphery of the tire body 222 along the axis of the rotating ring 221. The tire body 222 contacts the side wall of the track 4. When the base 1 moves along the extending direction of the track 4, the contact assembly 22 sleeved on the periphery of the dark box 21 rotates around the axis of the dark box 21. Due to the arrangement of the balance mechanism 6, the wear amounts of the two tire bodies 222 in the two near-rail measuring mechanisms 2 are basically the same after use. When measuring the values of a1 and a2, the first laser rangefinder 23 directly measures the side wall of the track 4. Since the first laser rangefinder 23 is relatively close to the side wall of the track 4, the laser emitted by the first laser rangefinder 23 will not decay too quickly, so the external light cannot have a great influence on the laser either, improving the accuracy of a1 and a2.

[0046] In one of the embodiments, refer to Figure 1 and Figure 9 , the near-rail measuring mechanism 2 further includes a tight-fitting member 24. The tight-fitting member 24 is fixedly arranged on the outer wall of the dark box 21. When the tight-fitting member 24 is electrified, the tight-fitting member 24 generates a magnetic suction force towards the side wall of the guide rail.

[0047] In this embodiment, the tight-fitting member 24 is a magnet block. The tight-fitting member 24 is fixedly arranged on the side of the dark box 21 close to the side wall of the track 4. When the laser detection vehicle is running, the tight-fitting member 24 is electrified, and the tight-fitting member 24 has an adsorption force on the track 4, so that the tire body 222 in the contact assembly 22 can better contact the track 4, and it is not easy to break away even during high-speed movement.

[0048] In one of the embodiments, refer to Figure 4 、 Figure 6 and Figure 8, the spacing measurement mechanism 3 includes a second laser rangefinder 31 and a path light-shielding tube 32. The path light-shielding tube 32 is a tubular structure with a stretching function. The path light-shielding tube 32 is horizontally fixed between two near-rail measurement mechanisms 2. A second measurement hole is formed on the side of the dark box 21 away from the track 4, and the second measurement hole is coaxially arranged with the path light-shielding tube 32. The second laser rangefinder 31 is fixedly arranged in the dark box 21, and the laser emitting end of the second laser rangefinder 31 faces the second measurement hole. The path light-shielding tube 32 wraps the laser path emitted by the second laser rangefinder 31.

[0049] In this embodiment, the extending direction of the second measurement hole is parallel to the width direction of the base 1. The path light-shielding tube 32 is a corrugated pipe. During the movement of the base 1, the second laser rangefinder 31 is always in an operating state. The second laser rangefinder 31 monitors the distance of the dark box 21 in the near-rail measurement mechanism 2 on the opposite side through the second measurement hole, so that the distance between the two near-rail measurement mechanisms 2 can be measured. Since the second measurement hole is coaxially arranged with the path light-shielding tube 32, the laser emitted by the second laser rangefinder 31 will completely penetrate the path light-shielding tube 32, and the external light is isolated by the path light-shielding tube 32, which will not affect the laser emitted by the second laser rangefinder 31, improving the accuracy of the value b.

[0050] In one of the embodiments, referring to Figure 11 and Figure 12 , the spacing measurement mechanism 3 further includes a support assembly 33. The support assembly 33 is movably arranged at the bottom of the path light-shielding tube 32 along the width direction of the base 1. The support assembly 33 includes a first support seat 331 and a second support seat 332. The first support seat 331 and the second support seat 332 are respectively fixedly connected to both ends of the bottom of the balance mechanism 6. The first support seat 331 is horizontally and evenly provided with a first insertion slot at one end close to the second support seat 332, and the second support seat 332 is horizontally and evenly provided with a second insertion slot at one end close to the first support seat 331. The first insertion slot and the second insertion slot are inserted, and the first support seat 331 and the second support seat 332 slide reciprocally along the width direction of the base 1.

[0051] In this embodiment, since the passage light-shielding tube 32 is a stretchable tubular structure, the self-supporting property of the passage light-shielding tube 32 is poor. If the support assembly 33 is not provided at the lower part of the passage light-shielding tube 32, the passage light-shielding tube 32 will bend under its own gravity. The bent passage light-shielding tube 32 due to gravity will obstruct the laser emitted by the second laser rangefinder 31. That is, after the passage light-shielding tube 32 bends, the laser emitted by the second laser rangefinder 31 is always a straight line and parallel to the width direction of the base 1. The bent passage light-shielding tube 32 will intercept the laser emitted by the second laser rangefinder 31 in advance, resulting in a large error in the measurement result. After the support assembly 33 is provided, the influence of the self-gravity of the passage light-shielding tube 32 can be reduced, thereby reducing the measurement error.

[0052] In one of the embodiments, referring to Figure 11 and Figure 12 , the distance measurement mechanism 3 further includes a windshield 34. The windshield 34 is disposed in parallel in front of the passage light-shielding tube 32, and the windshield 34 is fixedly connected to the passage light-shielding tube 32.

[0053] In this embodiment, since the passage light-shielding tube 32 is a stretchable tubular structure, the hardness of the passage light-shielding tube 32 itself is low. When the base 1 moves at a high speed along the extending direction of the track 4, the wind speed at the lower part of the base 1 is significantly increased. The high-speed flowing air easily causes the passage light-shielding tube 32 to deform, and then the passage light-shielding tube 32 is damaged. At the same time, the situation that the deformed passage light-shielding tube 32 blocks the laser emitted by the second laser rangefinder 31 will also occur, thus affecting the measurement result. Setting the windshield 34 in front of the passage light-shielding tube 32 can significantly reduce the influence of the high-speed flowing air on the passage light-shielding tube 32.

[0054] In one of the embodiments, referring to Figure 9 , the laser detection vehicle further includes a cleaning mechanism 7. The cleaning mechanism 7 includes a cleaning member 71 and a water supply pipe 72. The cleaning member 71 is disposed in front of the near-rail measurement mechanism 2. The cleaning member 71 is rotatably connected to the bottom of the base 1. The outer wall of the cleaning member 71 is uniformly provided with brushes, and the brushes are in contact with the side wall of the track 4. The water supply pipe 72 is fixedly disposed on the top of the cleaning member 71. The water supply pipe 72 is externally connected to a water source for supplying water to the cleaning member 71.

[0055] In this embodiment, when the base 1 moves along the extending direction of the track 4, the cleaning member 71 can pre-clean the side wall of the track 4 before the near-rail measurement mechanism 2 measures, improving the accuracy of the measurement result of the near-rail measurement mechanism 2.

[0056] The implementation principle of an intelligent remote-controlled gauge laser detection vehicle according to an embodiment of the present application is as follows: During measurement, the base 1 moves along the extension direction of the guide rail. The near-rail measurement mechanism 2 measures the side wall of the guide rail during the movement of the base 1. The two near-rail measurement mechanisms 2 respectively measure distances a1 and a2. Even during the measurement process, if the near-rail measurement mechanism 2 becomes disconnected due to the deformation of the track 4, the first laser rangefinder 23 in the near-rail measurement mechanism 2 can still measure the track 4. Since the first laser rangefinder 23 is relatively close to the side wall of the track 4, the laser is less affected by external light. In this way, the accuracy of a1 and a2 after measurement can be ensured. When measuring the distance between the two near-rail measurement mechanisms 2, the laser path emitted by the second laser rangefinder 31 is completely wrapped by the passage light-shielding tube 32, so that the second laser rangefinder 31 is not affected by external light at all. The distance b between the two near-rail measurement mechanisms 2 can be measured by the second laser rangefinder 31. Finally, by summing up a1, a2, and b, the gauge of the track 4 can be calculated, improving the measurement accuracy and reducing the influence of external light on laser detection.

[0057] The above embodiments only represent one or several implementation manners of the present invention, and the description thereof is relatively specific and detailed, but it should not be construed as a limitation to the scope of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, several modifications and improvements can still be made, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the present invention should be subject to the appended claims.
