[0024] It should be noted that the term "comprising" will be used in the embodiments of the present application to indicate the existence of the features declared thereafter, but does not exclude the addition of other features.
[0025] First, the application scenarios to which the present application is applicable are introduced. The present application can be applied in the field of track detection technology.
[0026] Research has found that track quality has a direct impact on the operation of rail vehicles on the track. Especially for crane tracks, the crane regulatory agency also has clear requirements for the quality of crane tracks. In order to ensure the safety and stable operation of the crane, accurate detection of its track is a crucial link.
[0027] Traditional track inspection methods rely on manual operation, requiring inspectors to hold inspection equipment to inspect the track. However, manual operation requires the operator to manually adjust the inspection equipment to the correct angle. This process is not only susceptible to interference from external factors such as wind, but manual adjustment is also difficult to maintain extreme accuracy. Therefore, this method has a large inherent error. Even if adverse factors such as wind are excluded during on-site inspections, it is difficult for humans to keep the inspection equipment in a horizontal position, resulting in large errors.
[0028] Especially for cranes in certain specific environments, such as steel plant metallurgical cranes and port cranes, their tracks are usually located at high altitudes, and the working environment is harsh and dangerous, which greatly increases the risk of manual inspection.

[0031] Specifically, the track detection device includes: a track fixing component, a bearing platform and a horizontal adjustment mechanism.
[0032] Wherein, the horizontal adjustment mechanism includes a plurality of height adjustment rods, and the plurality of height adjustment rods are respectively arranged at three preset second target positions.
[0033] Wherein, a screw hole is arranged at the first target position of the bearing platform.
[0034] The track fixing assembly includes a first connecting member and a second connecting member. The first connecting member has a slot at the bottom and a limit hook on the inner wall of the slot. The second connecting member has a driving wheel at the bottom and a spring guide wheel on the inner wall of the slot.
[0035] Specifically, a track fixing component, one side of which is formed with a predetermined shape matching the target track so as to be snapped onto the target track; a load-bearing platform, the load-bearing platform is used to place the detector; and a horizontal adjustment mechanism, the horizontal adjustment mechanism is arranged between the other side of the track fixing component and the load-bearing platform, and is used to level the load-bearing platform.
[0036] Specifically, the horizontal adjustment mechanism includes multiple height adjustment rods, one end of each height adjustment rod is connected to the other side of the track fixing assembly, and the other end of each height adjustment rod is connected to the supporting platform. The height adjustment rod is provided with an adjustment knob for adjusting the supporting length of the height adjustment rod.
[0037] Specifically, a screw hole is provided at the first target position of the horizontal storage platform, and the screw hole matches with the thread of the screw rod of the detector to fix the detector.
[0038] Specifically, the track fixing assembly includes a first connecting member and a second connecting member, the first connecting member is used to be engaged with the target track, the second connecting member is connected to the first connecting member and is located above the target track, and the second connecting member is connected to the horizontal adjustment mechanism.
[0039] Specifically, a clamping slot is provided at the bottom of the first connecting member; the target track is adapted to the clamping slot, and the connecting component is clamped with the target track through the clamping slot.
[0040] Specifically, a limiting hook is provided on the inner wall of the slot; the limiting hook extends in a horizontal direction and is sleeved outside the target track.
[0041] Specifically, a driving wheel is provided on the bottom surface of the second connecting member; the driving wheel cooperates with the top surface of the target track so that the bearing mechanism can move along the extension direction of the target track.
[0042] Specifically, a spring guide wheel is provided on the inner wall of the slot, one end of the spring of the spring guide wheel is connected to the inner wall of the slot, and the other end of the spring of the spring guide wheel is connected to the guide wheel rotating shaft of the spring guide wheel, so that the spring guide wheel is close to the side of the target track.
[0043] Specifically, a plurality of height adjustment rods are respectively arranged at three preset target positions to quickly level the supporting platform.
[0044] Here, the device has a stable and reliable mechanical structure design, which ensures that it can travel safely on the crane track under any circumstances, cannot fall from the crane track under any circumstances, and can ensure the stable operation of the sensors and instruments carried.
[0045] Optionally, the device further comprises a control unit, wherein the control unit is connected to the driving wheel so as to control the track detection device to move on the target track through the driving wheel.
[0046] Here, the device can use advanced automatic control technology to complete the inspection without human intervention in high-risk areas. It can autonomously navigate on the track and perform the required inspection tasks in manual remote control or automatic driving mode. All measurement data can be transmitted to a mobile phone application or inspection terminal in real time via wireless.
[0047] For example, the control unit can use a high-performance STM32 main controller based on the ARM-Cortex M3 core, combined with a drive motor with a Hall encoder and a metal gear reducer, so as to achieve remote precise control through a mobile phone application or a dedicated remote controller. Its intelligent control system can control a single or multiple devices at the same time, and the position, speed and other information of each device can be shared in real time, and collaborative detection work can be completed to improve detection efficiency.
[0048] For example, see Figure 2 , Figure 2 The schematic diagram shows the track detection device detecting the track Figure 1 .like Figure 2 As shown in FIG. 1 , a schematic diagram of the track detection device provided in an embodiment of the present application detecting a track Figure 1 , including: a rail 201, a track detection device 202, a track detection device 203, a collimated laser transmitter 204, and a receiving target 205.
[0049] Specifically, the collimated laser transmitter 204 and the receiving target 205 are respectively fixed on the track detection device 202 and the track detection device 203, and the track detection device 202 and the track detection device 203 are both fixed on the rail 201. The collimated laser emitted by the collimated laser transmitter can be emitted to the receiving target. According to the position of the laser point on the receiving target, the height difference of the rail 201 can be determined.
[0050] Exemplarily, both the track detection device 202 and the track detection device 203 can move on the rails according to the control of the control unit. The track detection device 202 and the track detection device 203 can move on the rails according to the control of the control unit.
[0051] In this way, according to the position of the laser point on the receiving target, it can be determined whether the height difference of different positions of the entire rail meets the standard. This avoids the need for inspectors to be directly exposed to a potentially dangerous environment when using manual inspection, reduces inspection errors, and improves inspection safety.
[0052] For example, see Figure 3 , Figure 3 The schematic diagram shows the track detection device detecting the track Figure 2 .like Figure 3 As shown in FIG. 1 , a schematic diagram of the track detection device provided in an embodiment of the present application detecting a track Figure 2 , including: a reflecting prism 301, a laser rangefinder 302, a track detection device 303, and a track detection device 304.
[0053] Specifically, the reflective prism 301 and the laser rangefinder 302 are fixed on the track detection device 304 and the track detection device 303 respectively, and the track detection device 304 and the track detection device 303 are fixed on two rails of the crane track 305 respectively.
[0054] The track detection device 304 is configured correspondingly to the track detection device 303. The distance measuring laser emitted by the laser rangefinder is emitted to the reflecting prism and then reflected back to the laser rangefinder. The laser rangefinder can determine the track gauge value L of the current position according to the time of reflecting back the laser.
[0055] Exemplarily, the track detection device 304 and the track detection device 303 may be controlled to move at a fixed moving speed, so that the laser rangefinder can detect the track gauge value at each position of the crane track.
[0056] For example, see Figure 4 , Figure 4 The schematic diagram shows the track detection device detecting the track Figure 3 .
[0057] like Figure 4 As shown in , two track detection devices can be respectively arranged on the two rails of the track, a collimated laser emitting device 4011 and a laser rangefinder 4012 are arranged on one track detection device of one rail 401, and a receiving target 4013 and a laser rangefinder 4014 are arranged on the other track detection device, and the laser rangefinder can be arranged in close contact with the collimated laser emitting device and the receiving target, and the collimated laser emitted by the collimated laser emitter can be emitted to the receiving target, and the height difference of the rail 401 can be determined according to the position of the laser point on the receiving target. A collimated laser emitting device 4021 and a reflecting prism 4022 can be arranged on one track detection device of the other rail 402, and a receiving target 4023 and a reflecting prism 4024 can be arranged on the other track detection device, and the collimated laser emitted by the collimated laser emitter can be emitted to the receiving target, and the height difference of the rail 402 can be determined according to the position of the laser point on the receiving target. The reflecting prism can be arranged in close contact with the collimating laser emitting device and the receiving target, and the position of the reflecting prism corresponds relatively to the position of the laser rangefinder.
[0058] Furthermore, the distance measuring laser emitted by the laser rangefinder 4012 on a track detection device on one rail 401 is emitted to the reflection prism 4022 of a track detection device on another rail 402, and then is reflected back to the laser rangefinder. The laser rangefinder can determine the track gauge value L1 at the current position based on the time it takes to reflect the laser back. The distance measuring laser emitted by the laser rangefinder 4014 on another track detection device on one rail 401 is emitted to the reflection prism 4024 of another track detection device on another rail 402, and then is reflected back to the laser rangefinder. The laser rangefinder can determine the track gauge value L2 at the current position based on the time it takes to reflect the laser back.
[0059] In this way, the movement of the four track detection devices on the track can be controlled, so that the height difference of each rail can be detected while the track gauge between two rails can be detected, further saving the detection time.
[0060] The track detection device proposed in the present application can be fixed on the track, and the detector can be placed on a leveled supporting platform. It no longer relies on manual operation and can complete the detection of the track by moving the track detection device to different positions, thereby avoiding direct exposure of detection personnel to potentially dangerous environments, reducing detection errors, and improving detection safety.
