Abstract
Description
Technical Field
[0001] This utility model belongs to the field of rail transit, specifically relating to a rail anti-expansion inspection device and system. Background Technology
[0002] my country has achieved remarkable success in railway construction, with its railway network stretching across the country like a giant dragon.
[0003] In the rapid development of railways, regular maintenance and replacement of tracks are crucial to ensure the safe operation of trains. Since track replacement involves a large number of tracks and takes a considerable amount of time, the replacement tracks (referred to as "replacement tracks") are often placed in advance on the side of the track, and the replacement is completed during a lull period.
[0004] When replacement rails are placed on the side of the track, they are often not secured and are exposed to direct sunlight for extended periods, leading to deformation and twisting due to increased temperature. When the replacement rails become twisted or deformed, especially at high temperatures and with significant deformation, they can easily encroach into the railway track, affecting the safe passage of trains and posing a safety hazard.
[0005] In practice, manual inspection is often used to determine whether the replacement track has been deformed or twisted. However, manual inspection is inefficient and increases the workload of staff. Utility Model Content
[0006] This utility model provides a track anti-expansion inspection device, which aims to solve the problem of low efficiency in the existing technology where track inspection is carried out manually.
[0007] To achieve the above objectives, this utility model provides a track anti-expansion inspection device, including...
[0008] A moving mechanism, the moving mechanism including a mounting frame and a track wheel module, the track wheel module being mounted on the mounting frame;
[0009] A detection module is mounted on the mounting frame. The moving mechanism can drive the detection module to move along the setting direction of the replacement track. The detection module is used to detect the replacement track.
[0010] This solution uses a moving mechanism as the power source to move along the replacement track. As the moving mechanism moves along the replacement track, the detection module, installed on the moving mechanism, can detect the replacement track. This solution, through the cooperation of the moving mechanism and the detection module, completes the inspection of the replacement track, which is more efficient than the manual inspection method used in existing technologies.
[0011] Preferably, in order to detect the replacement track, the detection module of this solution includes a camera, which is used to acquire images of the replacement track.
[0012] This solution uses a camera as the detection module, which captures images of the replacement track. Then, manual evaluation based on the images determines whether the replacement track has bulged, twisted, or encroached on the track line. If such phenomena are found, workers can promptly replace the track at that location.
[0013] Preferably, in order to facilitate quick and accurate determination of the status of the replacement track, the camera in this solution faces the front and / or rear of the moving mechanism.
[0014] In this solution, the camera is positioned facing forward and / or backward, thus providing a clearer view of the entire replacement track. Subsequent observations by staff can more quickly and accurately identify any issues such as expansion, twisting, or encroachment on the replacement track.
[0015] To avoid obstructing the camera, the camera in this solution is mounted on the end of the mounting bracket.
[0016] The preferred design is to mount the camera at the end of the mounting bracket. Therefore, when the camera can capture images from the front and / or rear of the mounting bracket, the camera will not be obstructed by the mounting bracket, and the images captured by the camera will be more complete and clear.
[0017] Preferably, in order to detect the replacement track, the detection module of this solution includes a temperature detector, which is used to collect the temperature of the replacement track.
[0018] In this solution, a temperature detector is used to monitor the temperature of the replacement track. When the temperature of the replacement track exceeds a threshold, it indicates that the track has likely experienced expansion or deformation. At this point, staff can promptly address the issue with the replacement track.
[0019] Preferably, to prevent the moving mechanism from derailing, the solution further includes a position detector, which is installed on the moving mechanism.
[0020] This solution uses a position detector to monitor the position of the moving mechanism. When the position detector detects that the moving mechanism is about to reach the end of the replacement track, the moving mechanism can decelerate and stop, thus preventing the moving mechanism from running off the replacement track.
[0021] Preferably, in order to enable the moving mechanism to move along the replacement track, the track wheel modules of this solution are installed on both sides of the mounting frame, and the track wheel modules on both sides are used to contact the two sides of the replacement track respectively.
[0022] In this design, the track wheel modules are positioned on both sides, contacting both sides of the replacement track. When the track wheel modules are in operation, the drive wheels on both sides engage with the sides of the replacement track for transmission. These drive wheels support the mounting frame, preventing it from tilting. Simultaneously, the rotation of the drive wheels on both sides moves the mounting frame along the replacement track.
[0023] Preferably, in order to facilitate the installation of the moving mechanism onto the replacement track and the removal of the moving mechanism from the replacement track, the mounting frame of this solution includes a first frame and a second frame, which are rotatably connected; the track wheel modules located on both sides of the mounting frame are respectively installed on the first frame and the second frame, and the first frame and the second frame rotate so that the track wheel modules contact or separate from the replacement track.
[0024] In this design, the mounting frame consists of a first frame and a second frame, both of which are rotatable. When the first and second frames rotate away from each other, the track wheel modules mounted on them separate from the replacement track; when they rotate closer together, the track wheel modules contact the replacement track. This design allows the moving mechanism to be installed and removed from the replacement track at any position, making it more flexible and convenient to use.
[0025] Preferably, in order to ensure that the mounting frame is more stable, the moving mechanism of this solution further includes a driven wheel module, which is mounted on the mounting frame and is arranged in a front-to-back manner with the track wheel module.
[0026] This design employs a driven wheel module and a track wheel module that work together, positioned one in front of the other to support the front and rear ends of the mounting frame. Therefore, when the mounting frame moves, it is supported by both the track wheel module and the driven wheel module, making it more stable and less prone to tilting compared to a mounting frame equipped with only a track wheel module.
[0027] Preferably, in order to make the moving structure more stable during movement, the moving mechanism of this solution further includes a stabilizing wheel module, which is installed on both sides of the mounting frame, and the stabilizing wheel modules on both sides are used to contact the two sides of the replacement track respectively.
[0028] This design also includes stabilizing wheel modules on the mounting frame. These modules are positioned on both sides and contact both sides of the replacement track. The stabilizing wheel modules on both sides abut against the replacement track, allowing the moving mechanism to be supported and making it more stable.
[0029] In order to enable remote personnel to be informed of the status of the replacement track in a timely manner, the second aspect of this utility model discloses a track anti-expansion inspection system, including the aforementioned track anti-expansion inspection device and inspection terminal, wherein the track anti-expansion inspection device and inspection terminal are signal connected.
[0030] In this solution, the track anti-expansion inspection device can collect relevant information about track replacement, and then feed this information back to the inspection terminal. Personnel at the inspection terminal can then promptly obtain information about the status of the replacement track based on the feedback from the track anti-expansion inspection device.
[0031] The beneficial effects of this invention are as follows: This solution uses a moving mechanism as the power source to move along the replacement track. When the moving mechanism moves along the replacement track, the detection module, installed on the moving mechanism, can detect the replacement track. This solution completes the inspection of the replacement track through the cooperation of the moving mechanism and the detection module, which is more efficient than the manual inspection method used in the prior art.

Detailed Implementation
[0042] To make the objectives, technical solutions, and advantages of the embodiments clearer, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. When the following description refers to the accompanying drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this disclosure.

[0043] It should be noted that all actions involving the acquisition of signals, information, or data in this application are carried out in compliance with the relevant data protection laws and policies of the country where the application is located, and with the authorization granted by the owner of the relevant device.
[0044] In this disclosure, unless otherwise stated, directional terms such as "inner" and "outer" are defined based on the contours of the corresponding components. Terms such as "first" and "second" used in this disclosure are for distinguishing one element from another and do not imply sequence or importance.
[0045] Example 1
[0046] The basics are as follows: Figure 1 and attached Figure 2 As shown, a track anti-expansion inspection device can automatically inspect along the replacement track, thereby solving the problems of low efficiency and large workload of manual inspection and replacement of tracks in the prior art.
[0047] like Figure 1 and attached Figure 2As shown, the track anti-bulging inspection device in this embodiment includes a moving mechanism 1, a detection module 2, and a position detector 3. The moving mechanism 1 can move along the setting direction of the replacement track, and the detection module 2 is mounted on the moving mechanism 1. When the moving mechanism 1 moves along the setting direction of the replacement track, the detection module 2 detects the replacement track on the moving path. The position detector 3 is also mounted on the moving mechanism 1. The position detector 3 is mainly used to determine whether the moving mechanism 1 is about to move to the end of the replacement track, thereby preventing the moving mechanism 1 from running off the replacement track.
[0048] like Figure 2 As shown, the moving mechanism 1 in this embodiment includes a mounting frame 11, a track wheel module 13, a driven wheel module 14, and a stabilizing wheel module 15. The mounting frame 11 serves as a mounting base for mounting the track wheel module 13, the driven wheel module 14, and the stabilizing wheel module 15.
[0049] like Figures 2-4 As shown, in this embodiment, the preferred mounting frame 11 includes a first frame 11a and a second frame 11b, which are symmetrically arranged on both sides and rotatably connected by a rotating component 11c. The rotating component 11c can be a hinge or other rotating components 11c in the prior art. The first frame 11a and the second frame 11b can rotate around the rotating component 11c. To ensure the connection stability of the first frame 11a and the second frame 11b, several rotating components 11c can be provided between them, for example, 2, 3, 4, or 5. The first frame 11a and the second frame 11b can be assembled by splicing and welding several metal plates, thereby forming a cavity inside the first frame 11a and the second frame 11b, which can hold electrical components such as batteries and cables.
[0050] It should be noted that the first frame 11a and the second frame 11b are rotatably connected. Therefore, when it is necessary to install the moving mechanism 1 onto the replacement track, firstly, the first frame 11a and the second frame 11b are rotated apart. Then, the replacement track is placed between the first frame 11a and the second frame 11b. Finally, the first frame 11a and the second frame 11b are rotated closer together to install the moving mechanism 1 onto the replacement track. When it is necessary to remove the moving mechanism 1 from the replacement track, the first frame 11a and the second frame 11b are rotated apart, moving away from the replacement track. Finally, the first frame 11a and the second frame 11b are removed from the replacement track. Through the above arrangement, it is ensured that the moving mechanism 1 can be installed and removed from any position on the replacement track.
[0051] Since the first frame 11a and the second frame 11b are rotatably connected, in order to ensure that the first frame 11a and the second frame 11b do not automatically separate during the operation of the moving mechanism 1, this embodiment also provides a locking structure 11d between the first frame 11a and the second frame 11b, such as... Figure 2 As shown. The locking structure 11d can be used to lock or unlock the first frame 11a and the second frame 11b. To ensure a more stable connection between the first frame 11a and the second frame 11b, several locking structures 11d can be provided as needed, such as 2, 3, 4, or 5. In this embodiment, the locking structure 11d is preferably a latch lock, with both ends of the latch lock installed on the sides of the first frame 11a and the second frame 11b respectively. The latch lock can be used to lock and unlock the first frame 11a and the second frame 11b. When the first frame 11a and the second frame 11b need to rotate, the latch lock is unlocked; when the first frame 11a and the second frame 11b need to be fixedly connected, the latch lock is locked.
[0052] It should be noted that in this embodiment, the locking structure 11d is set as a latch lock. However, it is obvious that in some other embodiments, the locking structure 11d can also be other locking structures 11d in the prior art.
[0053] To prevent damage to the moving mechanism 1 from hard collisions with external obstacles during movement, this embodiment includes anti-collision components at the ends of both the first frame 11a and the second frame 11b. These anti-collision components are made of rubber. They provide a certain degree of cushioning and protection, preventing damage to the moving mechanism 1 from hard collisions with external objects. In this embodiment, the anti-collision components can be cylindrical or rectangular blocks, and can be installed at both ends of the first frame 11a and the second frame 11b using fasteners or adhesive bonding, ensuring that both ends of the moving mechanism 1 are protected.
[0054] Since the first frame 11a and the second frame 11b are connected by a rotating component 11c, and electrical components can also be installed inside the first frame 11a and the second frame 11b, a protective cover 12 is also included in this embodiment to prevent external rainwater from corroding the rotating component 11c and damaging the electrical components. Figure 1 As shown. A protective cover 12 is installed on top of the first frame 11a and the second frame 11b. The protective cover 12 is a rectangular cover. One end of the protective cover 12 is hinged to the outer edge of the first frame 11a, and the protective cover 12 can rotate around the hinge, thus exposing the first frame 11a and the second frame 11b. A lock is provided on the opposite side of the hinge. When the protective cover 12 covers the top of the first frame 11a and the second frame 11b, the lock locks the protective cover 12. The lock can be a latch lock.
[0055] It should be noted that when the moving mechanism 1 is moving normally, the protective cover 12 shields the tops of the first frame 11a and the second frame 11b to prevent external rainwater from entering the device. When the moving mechanism 1 needs to be removed from the replacement track, in order to prevent the protective cover 12 from interfering with the rotation of the first frame 11a and the second frame 11b, the protective cover 12 must first be unlocked and rotated to a position where it does not interfere with the rotation of the first frame 11a and the second frame 11b. Finally, the first frame 11a and the second frame 11b can then be rotated normally.
[0056] To drive the mounting frame 11, two track wheel modules 13 are provided in this embodiment, and are respectively installed at the lower ends of the first frame 11a and the second frame 11b. The track wheel modules 13 are symmetrical, and the track wheel modules 13 on both sides can contact the lower parts of the replacement track on both sides respectively. In this embodiment, the track wheel module 13 includes a drive wheel, a drive motor, and a reducer. The drive motor is connected to the drive wheel through the reducer, so that the drive wheel can be driven to rotate by the drive motor. In order to install the track wheel module 13 at the lower end of the first frame 11a or the second frame 11b, in practice, the drive motor and the reducer can be installed at the lower end of the first frame 11a or the second frame 11b by configuring fasteners, and then the reducer is connected to the drive wheel through a transmission shaft, thereby ensuring that the drive wheel can be stably driven. In this embodiment, the drive wheel can be a rubber wheel.
[0057] It should be noted that because the replacement track has an I-shaped cross-section, the contact point between the drive wheel and the lower part of the replacement track is an inclined surface. Therefore, to ensure a closer fit between the drive wheel and the lower end of the replacement track, as follows: Figure 3 As shown, in this embodiment, the outer ring of the track wheel is preferably set as an inclined surface, that is, the track wheel as a whole is set in the shape of a frustum. The inclination angle of the outer ring of the track wheel is the same as the inclination angle of the lower part of the replacement track, so that the track wheel can fit completely with the lower part of the replacement track, thereby ensuring a better driving effect.
[0058] To ensure the mounting frame 11 does not tilt, two driven wheel modules 14 are provided in this embodiment, and are respectively installed at the lower ends of the first frame 11a and the second frame 11b. The driven wheel modules 14 are also symmetrically positioned and arranged in front of and behind the track wheel modules 13. The driven wheel modules 14 on both sides can contact the lower parts of both sides of the replacement track, such as... Figure 7 As shown. The track wheel modules 13 and driven wheel modules 14 on both sides are arranged in a rectangular symmetrical manner. The track wheel modules 13 on both sides support the front end of the mounting frame 11, and the driven wheel modules 14 on both sides support the rear end of the mounting frame 11.
[0059] like Figure 6As shown, the driven wheel module 14 in this embodiment specifically includes a mounting plate 14a, a driven wheel mounting seat 14b, and a driven wheel 14c. The mounting plate 14a is U-shaped and is mounted on the bottom of the first frame 11a or the second frame 11b by fasteners or welding. The mounting plate 14a has two connecting holes, and a first connecting rod 14d is disposed within each hole, allowing it to extend and retract within the connecting holes. The driven wheel mounting seat 14b is mounted below the mounting plate 14a and is fixedly connected to the lower part of the first connecting rod 14d. The driven wheel 14c is a rubber wheel and is rotatably mounted on the driven wheel mounting seat 14b. A first spring 14e is provided between the mounting plate 14a and the driven wheel mounting seat 14b, and the first spring 14e is sleeved on the first connecting rod 14d.
[0060] It is understandable that when the replacement track is twisted, if the driven wheel 14c is fixed, it may become suspended due to the twisting of the replacement track, thus preventing the mounting bracket 11 from maintaining stable movement. Therefore, this embodiment is equipped with a first spring 14e and a first connecting rod 14d. The first spring 14e keeps the driven wheel 14c pressed down, thereby ensuring that the driven wheel 14c is always in contact with the replacement track and preventing it from becoming suspended.
[0061] like Figure 7 As shown, since the cross-section of the replacement track is roughly I-shaped, the contact position between the driven wheel 14c and the lower part of the replacement track is an inclined surface. Therefore, to ensure that the driven wheel 14c can fit more closely with the lower end of the replacement track, in this embodiment, the lower surface of the mounting plate 14a is preferably set as an inclined surface. Thus, when the driven wheel mounting seat 14b is connected to the mounting plate 14a via the connecting rod, the driven wheel mounting seat 14b is in an inclined state. The driven wheel 14c mounted on the driven wheel mounting seat 14b is also in an inclined state. The driven wheel 14c, mounted in an inclined state, can fit more closely with the lower end of the replacement track, and the driven wheel 14c is in stable contact with the replacement track.
[0062] In this embodiment, the mounting frame 11 is driven by the cooperation of the track wheel module 13 and the driven wheel module 14. However, when the replacement track is twisted, the entire drive mechanism still has the risk of tipping over. Therefore, this embodiment also configures a stabilizing wheel module 15 on the mounting frame 11. There are at least four stabilizing wheel modules 15, which are arranged in a rectangular shape. The stabilizing wheel modules 15 are located above the track wheel module 13 and the driven wheel module 14. Of the four stabilizing wheel modules 15, two are installed on the first frame 11a and two are installed on the second frame 11b. When the moving mechanism 1 is on the replacement track, the stabilizing wheel modules 15 on the first frame 11a and the second frame 11b can respectively abut against the side walls of the replacement track, thereby ensuring that the moving mechanism 1 moves more stably and preventing tilting.
[0063] like Figure 8 and Figure 9 As shown, the stabilizing wheel module 15 in this embodiment includes a mounting block 15a, a stabilizing wheel mounting seat 15b, and a stabilizing wheel 15c. The mounting block 15a is fixedly mounted on the side of the first frame 11a or the second frame 11b. The mounting block 15a can be welded to the first frame 11a or the second frame 11b. A second connecting rod 15d is disposed on the mounting block 15a and is fixedly connected to the mounting block 15a. The second connecting rod 15d is in a horizontal state. The stabilizing wheel mounting seat 15b is provided with a connection port, and the end of the second connecting rod 15d is embedded in the connection port, allowing the second connecting rod 15d to extend and retract horizontally within the connection port. To prevent the second connecting rod 15d from detaching from the stabilizing wheel mounting seat 15b, this embodiment also provides a limiting part at the end of the second connecting rod 15d. A second spring 15e is provided between the mounting block 15a and the stabilizing wheel mounting seat 15b, and the second spring 15e is sleeved on the second connecting rod 15d. Two or more second connecting rods 15d can be configured between the mounting block 15a and the stabilizing wheel mounting base 15b, each connecting rod being fitted with a second spring 15e. The multiple second connecting rods 15d enhance the stability of the stabilizing wheel 15c. The stabilizing wheel 15c is rotatably mounted on the stabilizing wheel mounting base 15b, and the stabilizing wheel 15c is positioned horizontally.
[0064] Taking one application scenario as an example: when the replacement track expands and twists, the second spring 15e can push the stabilizing wheel mounting seat 15b, so that the stabilizing wheel 15c is tightly attached to the outer wall of the replacement track, preventing the stabilizing wheel 15c from being suspended and ensuring that the stabilizing wheel 15c can be tightly attached to the outer wall of the replacement track.
[0065] It should be noted that: the present disclosure provides a preferred moving mechanism 1, but in some other embodiments, the moving mechanism 1 can also be replaced by other moving mechanisms 1 in the prior art.
[0066] like Figure 5 As shown, to determine the status of the replacement track, the detection module 2 in this embodiment includes a camera 21 and a temperature detector 22. Two cameras 21 are configured in this embodiment, and are respectively fixedly installed at the front and rear ends of the mounting frame 11. The cameras 21 can simultaneously capture images of the replacement track at both the front and rear ends of the mounting frame 11, allowing remote manual identification to determine whether distortion has occurred. The temperature detector 22 in this embodiment can be an infrared thermometer, installed inside the first frame 11a and / or the second frame 11b. When the moving mechanism 1 is on the replacement track, the infrared thermometer faces the outer wall of the replacement track, and can measure the temperature of the outer wall of the replacement track.
[0067] It should be noted that: in this embodiment, it is preferred to configure both the camera 21 and the temperature detector 22. However, in some other embodiments, only one of the camera 21 and the temperature detector 22 may be configured. Alternatively, in some other embodiments, the detection module 2 may be other detection modules 2 available in the prior art.
[0068] To prevent the moving mechanism 1 from derailing, in this embodiment, position detectors 3 are mounted on the mounting frame 11, and at least two position detectors 3 are provided, located at opposite ends of the mounting frame 11. The position detectors 3 can be laser rangefinders, used to detect the distance between the end of the replacement track and the moving mechanism 1, thereby determining whether the moving mechanism 1 has moved to the end of the replacement track. Simultaneously, to facilitate accurate detection by the laser rangefinder, this embodiment also includes a baffle at the end of the replacement track. The baffle is used for detection by the laser rangefinder. The position detectors 3 are electrically connected to the control module, which in turn is electrically connected to the track wheel module 13 in the moving mechanism 1.
[0069] When position detector 3 determines that moving mechanism 1 has reached the end of the replacement track, the control module controls the moving wheel module to stop rotating, thus stopping moving mechanism 1. Afterwards, the control module can also control the moving wheel module to rotate in the opposite direction, causing moving mechanism 1 to move in the opposite direction along the replacement track. This process is repeated, enabling moving mechanism 1 to perform back-and-forth inspections on the replacement track.
[0070] It should be noted that in this embodiment, the position of the moving mechanism 1 is determined using a laser rangefinder. However, in some other embodiments, the position detector 3 can be other modules available in the prior art. For example, a radar module, which detects whether the moving mechanism 1 has moved to the end of the replacement track.
[0071] The following detailed explanation illustrates the specific implementation methods:
[0072] When a replacement track inspection is required, first rotate the protective cover 12 to a position where it does not interfere with the first frame 11a and the second frame 11b. Then, the user can rotate the first frame 11a and the second frame 11b so that the replacement track is positioned between them, allowing the moving mechanism 1 to be installed onto the replacement track. After the moving mechanism 1 is installed on the replacement track, the user rotates the protective cover 12 to cover the mounting frame 11, preventing external rainwater from entering. When the moving mechanism 1 is installed on the replacement track, it moves along the track. The detection module 2 mounted on the moving mechanism 1 performs inspections of the replacement track. The moving mechanism 1 can move back and forth on the replacement track, performing multiple precise inspections.
[0073] After the inspection is completed, the moving mechanism 1 needs to be separated from the replacement track. First, rotate the protective cover 12 to a position where it does not interfere with the first frame 11a and the second frame 11b. Then, the user can rotate the first frame 11a and the second frame 11b to separate them from the replacement track.
[0074] Example 2
[0075] This embodiment provides a track anti-expansion inspection system, including the track anti-expansion inspection device and inspection terminal as described in Embodiment 1. In this embodiment, the track anti-expansion inspection device and the inspection terminal are in a signal connection state. The track anti-expansion inspection device sends the detected replacement track status to the inspection terminal. The inspection terminal can be a monitoring terminal as described in the prior art, which includes a control module, a display screen for staff observation, and an operation panel for staff operation.
[0076] In this embodiment, the inspection terminal can be installed in a maintenance room, with relevant maintenance personnel stationed at the terminal. Once the maintenance personnel are aware of the status of the replacement track, they can promptly address any issues such as thermal expansion / torsion or intrusion into the replacement track along its path.
