Description

TECHNICAL FIELD

[0001] The utility model belongs to the track field, concretely relates to track moving mechanism and inspection device. BACKGROUND

[0002] In the process of rapid development of railway, in order to guarantee the safe operation of train, the periodic maintenance and replacement of track are very important. In the process of replacing track, since the track to be replaced is more, it needs to consume long time, so the track to be replaced (hereinafter referred to as "replacement track") is often placed on the side of line in advance, waiting for the window period of track, then the replacement of track is completed.

[0003] When the replacement track is placed on the side of line, since the replacement track is not fixed and is exposed to the sun for a long time, the problem of deformation and distortion of track due to temperature rise often occurs. When the replacement track deforms and distorts, especially in the case that the temperature is too high and the deformation amount of replacement track is large, the replacement track is easy to invade into the railway line, thereby affecting the safe passage of train, and there is a safety hazard.

[0004] In order to determine whether the replacement track deforms and distorts, in the prior art, the combination of satellite monitoring and manual inspection is often used. This method has low process efficiency and increases the workload of workers. Therefore, in order to solve the above problems, more and more technical personnel begin to research and develop the replacement track inspection device.

[0005] In the replacement track inspection device, the track moving mechanism that can move along the replacement track is very important. However, since the conventional moving mechanism used for moving along the normal track in the prior art is double-track type, that is, it needs to cooperate with two rails at the same time to realize the movement along the track (the conventional moving mechanism can refer to the prior art disclosed in the application number CN202211572777.6, named "a track intelligent inspection trolley"). Since the replacement track is single-track, the moving mechanism in the prior art cannot meet the use requirement of the replacement track inspection.

[0006] In summary, the track moving mechanism that can move on the replacement track is urgently needed in the prior art. CONTENT OF UTILITY MODEL

[0007] The utility model provides track moving mechanism and inspection device, and its purpose is to solve the problem that the track moving mechanism in the prior art cannot move along the replacement track.

[0008] In order to achieve the above purpose, the utility model provides a track moving mechanism, which comprises

[0009] A rack;

[0010] A driving wheel module is arranged at the lower end of the rack. When the moving mechanism is installed on the replacement track, the driving wheel modules at the two sides are in contact with the lower end of the replacement track. The driving wheel modules at the two sides cooperate with each other, so that the moving mechanism can move along the replacement track. The driving wheel modules at the two sides are used to drive the moving mechanism to move along the replacement track, which solves the problem of the prior art.

[0011] The driving wheel modules at the two sides are arranged on the rack. When the moving mechanism is installed on the replacement track, the driving wheel modules at the two sides are in contact with the lower end of the replacement track. The driving wheel modules at the two sides cooperate with each other, so that the moving mechanism can move along the replacement track. The driving wheel modules at the two sides are used to drive the moving mechanism to move along the replacement track, which solves the problem of the prior art.

[0012] Preferably, in order to ensure that the rack is more stable, the present application further comprises a driven wheel module arranged at the lower end of the rack, and the driven wheel module is arranged in front of and behind the driving wheel module. The driven wheel module comprises a driven wheel, and the driven wheel can be in contact with the lower end of the replacement track.

[0013] The driven wheel module and the driving wheel module cooperate with each other, and the driven wheel module and the driving wheel module are arranged in front of and behind the rack to support the front end and the rear end of the rack. Therefore, when the rack moves, the rack is supported by the cooperation of the driving wheel module and the driven wheel module. Compared with only arranging the driving wheel module, the rack is more stable and is not easy to tilt.

[0014] Preferably, since the replacement track is prone to distortion when subjected to high temperature, the driven wheel is at risk of being suspended at this time. The driven wheel module of the present application further comprises a mounting plate, a driven wheel mounting seat and a first spring, the mounting plate is mounted on the rack, the driven wheel is mounted on the driven wheel mounting seat, and the first spring is in contact with the mounting plate and the driven wheel mounting seat at both ends.

[0015] A first connecting rod is arranged between the mounting plate and the driven wheel mounting seat, and the first connecting rod is used to guide the driven wheel mounting seat to move up and down.

[0016] In the present application, the driven wheel is mounted on the driven wheel mounting seat, and the driven wheel mounting seat can move up and down along the arrangement direction of the first connecting rod. Therefore, when the replacement track is distorted, the driven wheel can move up and down to adjust the distance between the driven wheel and the replacement track, so that the driven wheel can be attached to the replacement track, and the driven wheel is prevented from being suspended.

[0017] Preferably, since the contact position between the replacement track and the driven wheel is an inclined surface, in order to ensure that the driven wheel is more attached to the replacement track, the driven wheel module of the present application is inclinedly mounted on the rack.

[0018] When the driven wheel is installed obliquely, the driven wheel is in contact with the oblique replacement track contact surface. The support effect of the driven wheel on the frame is better.

[0019] Preferably, in order to make the moving structure more stable during movement, the scheme further comprises a stabilizing wheel module, which is installed on the frame, and the stabilizing wheel module is installed on both sides of the frame, and the stabilizing wheel module comprises a stabilizing wheel, which can be in contact with the side wall of the replacement track.

[0020] The stabilizing wheel module of the scheme is in contact with the two side walls of the replacement track, so when the moving mechanism is on the replacement track, the stabilizing wheel modules on both sides can provide support for the frame, preventing the frame from tilting or falling during movement, and the moving mechanism moves more stably.

[0021] Preferably, since the replacement track is prone to distortion when subjected to high temperature, the stabilizing wheel is at risk of being suspended. The stabilizing wheel module of the scheme comprises a mounting block, a stabilizing wheel mounting seat, and a second spring, the mounting block is installed on the frame, the stabilizing wheel is installed on the stabilizing wheel mounting seat, and the second spring is in contact with the mounting block and the stabilizing wheel mounting seat at both ends.

[0022] A second connecting rod is arranged between the mounting block and the stabilizing wheel mounting seat, and the second connecting rod is used to guide the left and right movement of the stabilizing wheel mounting seat.

[0023] In the scheme, the stabilizing wheel is installed on the stabilizing wheel mounting seat, and the stabilizing wheel mounting seat can move up and down along the arrangement direction of the second connecting rod. Therefore, when the replacement track is distorted, the stabilizing wheel can move left and right to adjust the distance between the stabilizing wheel and the replacement track, ensuring that the stabilizing wheel can fit the replacement track and avoiding the stabilizing wheel being suspended.

[0024] Preferably, in order to make the stabilizing wheel module achieve better stability, the stabilizing wheel module of the scheme is arranged to be at least three, and is symmetrically arranged on both sides of the frame.

[0025] In the scheme, at least three stabilizing wheel modules are arranged to cooperate with each other, compared with arranging only two stabilizing wheel modules, three stabilizing wheel modules can support more positions of the frame, making the frame more stable.

[0026] Preferably, in order to facilitate the installation and removal of the moving mechanism to / from the replacement track, the frame of the scheme comprises a first frame body and a second frame body, and the first frame body and the second frame body are rotatably connected.

[0027] The driving wheel modules on both sides are respectively installed on the first frame body and the second frame body, and the first frame body and the second frame body are rotated to make the driving wheel modules contact or move away from the replacement track.

[0028] In the scheme, the rack is provided as a first rack body and a second rack body, and the first rack body and the second rack body can rotate. When the first rack body and the second rack body rotate away, the driving wheel module mounted on the first rack body and the second rack body is separated from the replacement track; when the first rack body and the second rack body rotate close, the driving wheel module mounted on the first rack body and the second rack body is in contact with the replacement track. Through the above design, the moving mechanism can be installed and removed at any position of the replacement track, and the moving mechanism is more flexible and convenient to use.

[0029] Since the contact position of the replacement track and the driven wheel is an inclined surface, in order to ensure that the driven wheel and the replacement track are more fitted, the outer edge of the driving wheel is provided as an inclined surface.

[0030] When the outer edge of the driving wheel is provided as an inclined surface, the driving wheel and the inclined replacement track contact surface are fitted.

[0031] In order to realize the inspection of the replacement track, the utility model provides a second aspect of the inspection device, including the above-mentioned track moving mechanism and detection module, the detection module is installed on the track moving mechanism.

[0032] The scheme moves along the replacement track by the track moving mechanism as a power. When the track moving mechanism moves along the replacement track, since the detection module is installed on the track moving mechanism, the detection module can realize the detection of the replacement track.

[0033] Preferably, in order to realize the detection of the replacement track, the detection module comprises a camera, the camera is installed on the track moving mechanism, and the camera is used for collecting replacement track images.

[0034] The scheme provides the detection module as a camera, and the camera can collect images of the replacement track. Then, the image is judged by manual, and then it is determined whether the replacement track appears expansion distortion, intrusion along the track and the like. If the replacement track appears expansion distortion, intrusion along the track and the like, the replacement track at the position can be replaced in time by the worker.

[0035] In order to realize the detection of the replacement track, the detection module comprises a temperature detector, the temperature detector is installed on the track moving mechanism, and the temperature detector is used for collecting replacement track temperature.

[0049] In order to make the purpose, technical scheme and advantages of the embodiments clearer, the utility model will be further described in detail below in combination with the drawings and embodiments. When the following description refers to the drawings, the same numbers in different drawings represent the same or similar elements unless otherwise indicated.

[0050] It should be noted that all actions of obtaining signals, information or data in this application are carried out in accordance with the corresponding data protection regulations and policies of the place, and with the authorization of the owner of the corresponding device.

[0051] In the present disclosure, the orientation words such as "inner" and "outer" are defined according to the contour of the corresponding parts, unless otherwise stated. The terms such as "first" and "second" used in the present disclosure are used to distinguish one element from another element, and do not have sequentiality and importance.

[0052] Embodiment 1

[0053] Basically as shown in the accompanying Figure 1 to the accompanying Figure 2 , a track moving mechanism can move along a replacement track to meet the use needs of the replacement track inspection device and solve the problems of the prior art.

[0054] As shown in Figure 1 and Figure 2 , the track moving mechanism in the present embodiment includes a rack 1, a driving wheel module 3, a driven wheel module 4 and a stabilizing wheel module 5. The rack 1 is used as a mounting base for the driving wheel module 3, the driven wheel module 4 and the stabilizing wheel module 5.

[0055] As shown in Figure 3 and Figure 4As shown, the preferred rack 1 in the embodiment includes a first rack body 1a and a second rack body 1b, which are symmetrically arranged on both sides and are rotatably connected through a rotating part 1c. The rotating part 1c can be a hinge or other rotating part 1c in the prior art. The first rack body 1a and the second rack body 1b can rotate around the rotating part 1c. At the same time, in order to ensure the connection stability of the first rack body 1a and the second rack body 1b, the rotating part 1c between the first rack body 1a and the second rack body 1b can be provided with several, for example, 2, 3, 4 or 5, etc. The first rack body 1a and the second rack body 1b can be combined by welding several metal plates, so as to form a cavity inside the first rack body 1a and the second rack body 1b, and the cavity can accommodate electrical elements such as batteries and cables.

[0056] It should be noted that, since the first rack body 1a and the second rack body 1b are rotatably connected. Therefore, when it is needed to install the moving mechanism on the replacement track, first, the first rack body 1a and the second rack body 1b are rotated and separated, then the replacement track is placed between the first rack body 1a and the second rack body 1b, and finally the first rack body 1a and the second rack body 1b are rotated and approached, so as to realize the installation of the moving mechanism on the replacement track. When it is needed to remove the moving mechanism from the replacement track, the first rack body 1a and the second rack body 1b are rotated and separated, the first rack body 1a and the second rack body 1b are away from the replacement track, and finally the first rack body 1a and the second rack body 1b are removed from the replacement track. Through the above arrangement, it is ensured that the moving mechanism can be installed and removed at any position of the replacement track.

[0057] Since the first rack body 1a and the second rack body 1b are rotatably connected, in order to ensure that the first rack body 1a and the second rack body 1b will not automatically separate during the operation of the moving mechanism, for example, Figure 2 As shown, the embodiment further configures a locking structure 1d between the first rack body 1a and the second rack body 1b. The locking structure 1d can realize the fixed locking or unlocking of the first rack body 1a and the second rack body 1b. In order to ensure the connection stability of the first rack body 1a and the second rack body 1b, the locking structure 1d can also be provided with several, for example, 2, 3, 4 or 5, etc. The locking structure 1d of the embodiment is preferably a snap lock, and the two ends of the snap lock are respectively installed on the side surfaces of the first rack body 1a and the second rack body 1b. The snap lock can realize the locking and unlocking of the first rack body 1a and the second rack body 1b. When the first rack body 1a and the second rack body 1b need to be rotated, the snap lock is unlocked; when the first rack body 1a and the second rack body 1b need to be fixedly connected, the snap lock is locked.

[0058] It should be noted that the locking structure 1d in this embodiment is set as a snap lock. However, it is obvious that in some other embodiments, the locking structure 1d can also be other locking structures 1d in the prior art.

[0059] In order to avoid the mobile mechanism from being damaged by hard collision with external obstacles during movement, the anti-collision components made of rubber are arranged at the ends of the first frame body 1a and the second frame body 1b in this embodiment. The anti-collision components can have a certain buffering protection effect, so as to avoid the mobile mechanism from being damaged by hard collision with the outside. The anti-collision components in this embodiment can be cylindrical or rectangular block-shaped, which can be installed at the two ends of the first frame body 1a and the second frame body 1b through fasteners or adhesion, so as to ensure that the two ends of the mobile mechanism are protected.

[0060] Since the first frame body 1a and the second frame body 1b are connected through the rotating component 1c, and at the same time, the first frame body 1a and the second frame body 1b can also have electrical elements inside. In order to prevent external rainwater from corroding the rotating component 1c and causing damage to the electrical elements, the rack 1 in this embodiment also includes a protective cover 2. The protective cover 2 is installed at the top of the first frame body 1a and the second frame body 1b. The protective cover 2 is a rectangular cover body. One end of the protective cover 2 is installed at the outer edge of the first frame body 1a through a hinge, and the protective cover 2 can be rotated around the hinge, so as to expose the first frame body 1a and the second frame body 1b. At the same time, a lock 2a is arranged at the opposite side of the hinge. When the protective cover 2 covers the top of the first frame body 1a and the second frame body 1b, the lock 2a locks the protective cover 2, and the lock 2a can be a snap lock. As shown in Figure 1 .

[0061] It should be noted that when the mobile mechanism moves normally, the protective cover 2 covers the top of the first frame body 1a and the second frame body 1b, so as to prevent external rainwater from entering the inside of the device. When it is necessary to remove the mobile mechanism from the replacement track, in order to prevent the protective cover 2 from interfering with the rotation of the first frame body 1a and the second frame body 1b, it is necessary to first unlock the protective cover 2, and then rotate the protective cover 2 to a position where the protective cover 2 does not interfere with the first frame body 1a and the second frame body 1b. Finally, the first frame body 1a and the second frame body 1b can be normally rotated.

[0062] In order to realize the driving of the rack 1, the driving wheel module 3 in the embodiment is provided as two and is respectively installed at the lower end of the first rack body 1a and the second rack body 1b. The driving wheel module 3 is in a symmetrical state, and the driving wheel modules 3 on both sides can respectively contact the lower part of the two sides of the replacement track. The driving wheel module 3 in the embodiment includes a driving wheel, a driving motor and a speed reducer, the driving motor is in transmission connection with the driving wheel through the speed reducer, so that the driving wheel can be driven to rotate by the driving motor. In order to install the driving wheel module 3 at the lower end of the first rack body 1a or the second rack body 1b, in the implementation, the driving motor and the speed reducer can be installed at the lower end of the first rack body 1a or the second rack body 1b by configuring fasteners, and then the speed reducer is in transmission connection with the driving wheel through a transmission shaft, so as to ensure that the driving wheel can be stably driven. The driving wheel in the embodiment can be a rubber wheel. As shown in Figure 5

[0063] It should be noted that: since the cross section of the replacement track is a "work" shape, the contact position of the driving wheel with the lower part of the replacement track is an inclined surface. Therefore, in order to ensure that the driving wheel can be more fitted with the lower end of the replacement track, the outer ring of the track wheel in the embodiment is preferably provided as an inclined surface, that is, the track wheel is provided as a circular truncated cone as a whole. The inclined angle of the outer ring of the track wheel is the same as the inclined angle of the lower part of the replacement track, so that the track wheel can be completely fitted with the lower part of the replacement track, thereby ensuring better driving effect.

[0064] As shown in Figure 6 and Figure 7 In order to ensure that the rack 1 will not tilt, the driven wheel module 4 in the embodiment is also provided as two and is respectively installed at the lower end of the first rack body 1a and the second rack body 1b. The driven wheel module 4 is also in a symmetrical state and is arranged before and after the driving wheel module 3. The driven wheel modules 4 on both sides can respectively contact the lower part of the two sides of the replacement track. The driving wheel modules 3 on both sides and the driven wheel modules 4 on both sides are arranged in a rectangular symmetry, the driving wheel modules 3 on both sides support the front end of the rack 1, and the driven wheel modules 4 on both sides support the rear end of the rack 1.

[0065] The driven wheel module 4 in the embodiment specifically includes a mounting plate 4a, a driven wheel mounting seat 4b and a driven wheel 4c. The mounting plate 4a is U-shaped and is installed at the bottom of the first rack body 1a or the second rack body 1b by configuring fasteners or welding. Two connecting holes are formed on the mounting plate 4a, a first connecting rod 4d is arranged in the connecting hole, and the first connecting rod 4d can be telescopic in the connecting hole. The driven wheel mounting seat 4b is installed below the mounting plate 4a, and the driven wheel mounting seat 4b is fixedly connected with the lower part of the first connecting rod 4d. The driven wheel 4c is a rubber wheel and is rotatably installed on the driven wheel mounting seat 4b. Meanwhile, a first spring 4e is arranged between the mounting plate 4a and the driven wheel mounting seat 4b, and the first spring 4e is sleeved on the first connecting rod 4d.​

[0066] It is understandable that when the replacement track is twisted, if the driven wheel 4c is fixed, it may become suspended due to the twisting of the replacement track, causing the frame 1 to be unable to maintain stable movement. Therefore, this embodiment is equipped with a first spring 4e and a first connecting rod 4d. The first spring 4e keeps the driven wheel 4c pressed down, thereby ensuring that the driven wheel 4c can always be in contact with the replacement track and preventing the driven wheel 4c from becoming suspended.

[0067] Because the cross-section of the replacement track is roughly I-shaped, the lower contact point between the driven wheel 4c and the replacement track is an inclined surface. Therefore, to ensure a closer fit between the driven wheel 4c and the lower end of the replacement track, this embodiment preferably sets the lower surface of the mounting plate 4a as an inclined surface. Thus, when the driven wheel mounting base 4b is connected to the mounting plate 4a via a connecting rod, the driven wheel mounting base 4b is in an inclined state. The driven wheel 4c mounted on the driven wheel mounting base 4b is also in an inclined state. The driven wheel 4c, installed in an inclined state, can fit more closely to the lower end of the replacement track, ensuring stable contact between the driven wheel 4c and the replacement track.

[0068] like Figure 7 and Figure 8 As shown, in this embodiment, the drive wheel module 3 and the driven wheel module 4 cooperate to drive the frame 1. 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 5 on the frame 1. At least three stabilizing wheel modules 5 are provided, and the four stabilizing wheel modules 5 are arranged in a rectangular pattern. The stabilizing wheel modules 5 are located above the drive wheel module 3 and the driven wheel module 4. Of the four stabilizing wheel modules 5, two are installed on the first frame 1a and two are installed on the second frame 1b. When the moving mechanism is on the replacement track, the stabilizing wheel modules 5 located on the first frame 1a and the second frame 1b can respectively abut against the side walls of the replacement track, thereby ensuring more stable movement of the moving mechanism and preventing tilting.

[0069] like Figure 8As shown, the stabilizing wheel module 5 in this embodiment includes a mounting block 5a, a stabilizing wheel mounting seat 5b, and a stabilizing wheel 5c. The mounting block 5a is fixedly mounted on the side of the first frame 1a or the second frame 1b. The mounting block 5a can be welded to the first frame 1a or the second frame 1b. A second connecting rod 5d is disposed on the mounting block 5a and is fixedly connected to the mounting block 5a. The second connecting rod 5d is in a horizontal state. The stabilizing wheel mounting seat 5b is provided with a connection port, and the end of the second connecting rod 5d is embedded in the connection port, allowing the second connecting rod 5d to extend and retract horizontally within the connection port. To prevent the second connecting rod 5d from detaching from the stabilizing wheel mounting seat 5b, this embodiment also provides a limiting part at the end of the second connecting rod 5d. A second spring 5e is disposed between the mounting block 5a and the stabilizing wheel mounting seat 5b, and the second spring 5e is sleeved on the second connecting rod 5d. Two or more second connecting rods 5d can be disposed between the mounting block 5a and the stabilizing wheel mounting seat 5b, and each connecting rod is sleeved with a second spring 5e. The stabilizing wheel 5c is made more stable by multiple second connecting rods 5d. The stabilizing wheel 5c is rotatably mounted on the stabilizing wheel mounting base 5b, and the stabilizing wheel 5c is set in a horizontal position.

[0070] For example, in one application scenario: when the replacement track expands or twists, the second spring 5e can push the stabilizing wheel mounting base 5b, causing the stabilizing wheel 5c to fit tightly against the outer wall of the replacement track, preventing the stabilizing wheel 5c from being suspended and ensuring that the stabilizing wheel 5c can fit tightly against the outer wall of the replacement track. Figure 9 As shown.

[0071] Example 2

[0072] This embodiment provides a track inspection device, such as... Figure 10 As shown, it includes the track moving mechanism, detection module 6 and position detector 7 as in Embodiment 1.

[0073] In this embodiment, the track moving mechanism can move along the direction of the replacement track, and the detection module 6 is installed on the track moving mechanism. When the track moving mechanism moves along the direction of the replacement track, the detection module 6 detects the replacement track on the moving path. The position detector 7 is also installed on the track moving mechanism. The position detector 7 is mainly used to determine whether the track moving mechanism is about to move to the end of the track, thereby preventing the track moving mechanism from running off the replacement track.

[0074] The detection module 6 in the embodiment includes a camera 6a and a temperature detector 6b. The camera 6a in the embodiment is provided in two and is fixedly installed at the front end and the rear end of the rack 1 respectively. The camera 6a can simultaneously shoot the replacement track images at the front end and the rear end of the rack 1, so as to provide the remote work personnel to identify whether the distortion occurs. The temperature detector 6b in the embodiment can be an infrared thermometer. The infrared thermometer is installed at the inner side of the first rack body 1a and / or the second rack body 1b. When the moving mechanism is on the replacement track, the infrared thermometer faces the outer side wall of the replacement track. The infrared thermometer can measure the temperature of the outer wall of the replacement track.

[0075] It should be noted that: in the embodiment, the camera 6a and the temperature detector 6b are preferably configured at the same time, but in some other embodiments, only one of the camera 6a and the temperature detector 6b can be configured. Alternatively, in some other embodiments, the detection module 6 can also be other detection modules 6 in the prior art.

[0076] In order to prevent the moving mechanism from derailing, the position detector 7 in the embodiment is installed on the rack 1, and the position detector 7 is provided in at least two and is located at both ends of the rack 1. The position detector 7 can be a laser range finder. The laser range finder is used to detect the distance between the end of the replacement track and the moving mechanism, so as to determine whether the moving mechanism has moved to the end of the replacement track. At the same time, in order to facilitate the accurate detection of the laser range finder, the embodiment further provides a baffle at the end of the replacement track. The baffle is used for the laser range finder to detect. The position detector 7 is in an electrically connected state with the control module, and the control module is in an electrically connected state with the driving wheel module 3 in the moving mechanism.

[0077] When the position detector 7 determines that the moving mechanism has reached the end of the replacement track, the control module controls the moving wheel module to stop rotating, so as to stop the moving mechanism. Then, the control module can also control the moving wheel module to rotate reversely, so that the moving mechanism moves reversely along the replacement track. The above process is repeated, so as to realize the back-and-forth inspection of the moving mechanism on the replacement track.

[0078] It should be noted that: in the embodiment, the laser range finder is used to determine the position of the track. However, in some other embodiments, the position detector 7 can be other modules in the prior art. For example, a radar module is used to detect whether the moving mechanism moves to the end of the replacement track.

[0079] The specific working process of the track inspection device will be described below.

[0080] When the replacement track needs to be inspected, the protective cover 2 is first rotated so that the protective cover 2 is moved to a position where the protective cover 2 does not interfere with the first frame body 1a and the second frame body 1b. Then the user can rotate the first frame body 1a and the second frame body 1b so that the replacement track is located between the first frame body 1a and the second frame body 1b, and the moving mechanism is installed on the replacement track. After the moving mechanism is installed on the replacement track, the user rotates the protective cover 2 so that the protective cover 2 shields the rack 1, preventing external rainwater from entering. When the moving mechanism is installed on the replacement track, the moving mechanism moves along the replacement track. The detection module 6 installed on the moving mechanism detects the replacement track. The moving mechanism can move back and forth on the replacement track to accurately detect the replacement track multiple times.
