Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of track detection, and particularly relates to a track flatness rapid detection device of a track inspection robot. BACKGROUND

[0002] The safety and accuracy of a track directly affect the normal operation and work efficiency of equipment, and therefore, periodic detection and maintenance of the track are crucial. The main purpose of track detection is to evaluate the geometric state, flatness, bearing capacity and structural integrity of the track. In order to timely find potential problems of the track, a track flatness detection device needs to be used. However, the existing track flatness detection device still has some deficiencies.

[0003] The patent for invention with the publication number CN110861665B discloses a multifunctional track structure detection vehicle, which comprises a vehicle body, a laser profile sensor and a space positioning mechanism. The laser profile sensor is connected with the vehicle body through the space positioning mechanism, thereby having a joint gap detection position and a cushion plate thickness detection position. At the joint gap detection position, the laser profile sensor is horizontally opposite to the joint between the track plate and the support layer, and the laser emission direction thereof is parallel to the horizontal direction. At the cushion plate thickness detection position, the laser profile sensor is located above the fastener on the outer side or the inner side of the steel rail, and the laser emission direction thereof is parallel to the vertical direction. The space positioning mechanism changes the spatial position of the laser profile sensor, so that the laser profile sensor can meet the requirements of joint gap detection and cushion plate thickness detection, thereby reducing the number of track structure detection devices and maintenance costs, and reducing the work intensity of maintenance personnel. Although the above-mentioned device can realize the function of reducing maintenance costs, it cannot switch the structure mode according to the track structure when in use, cannot adapt to the use of suspended tracks or ground tracks, and cannot adapt to the use of tracks with different widths.

[0004] The invention patent with the publication number CN104029694B discloses a contact rail detection rail trolley, which comprises a rail trolley, a mechanical detection device and a signal detection device. The rail trolley is provided with the mechanical detection device. The mechanical detection device comprises a horizontal distance detection mechanical device and a vertical distance detection mechanical device. The horizontal distance detection mechanical device detects the distance deviation error of the center of the current collecting surface of the contact rail to the inner side of the adjacent steel rail. The vertical distance detection mechanical device detects the distance deviation error of the current collecting surface of the contact rail to the extension line of the top surface of the two steel rails. The horizontal distance deviation error and the vertical distance deviation error are outputted by the signal detection device through the detection data of the detection mechanical device. The device can detect the installation accuracy of any point of the contact rail along the line and make a prompt. Although the above device can detect the installation accuracy, the existing detection device is usually slidably installed on the rail. The detection head is used for detection in the moving process. Although the flatness detection function can be realized, the detection accuracy cannot be adjusted according to the needs. The detection precision cannot be switched between the roller detection and the ball detection. The two detection modes of long distance rapid detection and local fine detection cannot be simultaneously satisfied. Moreover, the detection range cannot be adjusted. SUMMARY

[0010] As a further further scheme of the present application: the adapter block is a spherical structure, and the adapter blocks are uniformly arranged along the circumference of the adapter disc.

[0011] As a further further scheme of the present application: the traction assembly comprises the traction steel rope fixedly connected with the first clamping block, the first spring is arranged between the first clamping block and the rotating plate, the guide groove is arranged on the rotating plate, the adapter ring is rotationally arranged in the rotating plate, and the traction plate is fixedly connected with the adapter ring.

[0016] Compared with the prior art, the present application has the following advantages: 1、Through the setting of the roller, guide block, adapter disc and adapter block, the function of switching the detection mode is realized. When the device is placed horizontally, the flatness of the ground track can be detected. The adapter disc can abut the left and right sides of the track, and the roller can contact the upper surface of the track to realize the function of straight travel. When the device is adapted to the ground track, the adapter block can ensure that the adapter disc abuts the left and right sides of the track while reducing the moving resistance of the device. When the device is in a lateral suspension state, the device can be adapted to the suspension track. The adapter block with a spherical structure cooperates with the roller to make the shell of the device travel along the track when it is in a lateral pressure state. The initial position of the displacement sensor is adjusted by the first electric push rod to detect the side of the suspension track.

[0017] 2、Through the setting of the traction assembly and the synchronous adjustment assembly, the function of adapting to different width tracks is realized. The device can adapt to different width tracks by adjusting the distance between the adapter disc and the roller. When adjusting, only need to rotate one side of the synchronous wheel. Through the synchronous belt, the other side of the synchronous wheel is driven to rotate synchronously. When the synchronous wheel rotates, it will first pull the traction steel rope through the adapter plate. The traction steel rope pulls the first clamping block to make it disengage from the docking groove. When the rotating plate disengages from the adapter disc, the traction steel rope acts on the rotating plate to make it rotate until the first clamping block moves to the next docking groove. In this process, the spline block rotates in the key groove, thereby driving the stud to rotate. The stud rotates to make the adapter disc slide under the guidance of the guide block, thereby adjusting the distance between the roller and the adapter disc to adapt to different width tracks. The existing track detection device cannot adapt to different width tracks. The device only needs to rotate the synchronous wheel to realize the three steps of disengaging the adapter disc and the roller, adjusting the distance between the adapter disc and the roller, and re-engaging. Compared with the conventional adjustment structure, the device is more convenient to adjust.

[0018] 3、The device is provided with a detection assembly and a first electric push rod. When accurate detection of the flatness of the track surface is required, the first connecting shell can be rotated to be directly below the top block. The top block can push the first connecting shell until the second pressing block abuts the inner wall of the rotating shaft. At this time, the bottom height of the roller is less than the bottom height of the ball, so that the device only contacts the track through the ball for flatness detection. During detection, the device can be driven as a whole by the roller to perform dynamic detection, or the device can remain stationary and the detection assembly can be moved as a whole by the driving assembly to perform static detection, thereby enhancing the adaptability of the device and enabling the device to switch between local detection and overall detection.

[0019] 4. By lengthening or shortening the second electric push rod, the left and right positions of the first connecting shell and the second connecting shell relative to the track are adjusted, so that the specific position is accurately detected, the device can be switched to the roller detection, by rotating the first and second connecting shells, the top of the second connecting shell is in abutment with the top block, at this time the bottom of the roller is in abutment with the surface of the track, the ball and the first connecting shell move upward under the action of the second tension spring, so that long distance rapid detection is realized by using the roller, the problem that the existing flatness detection device cannot simultaneously satisfy the two detection modes of long distance rapid detection and local fine detection is solved, and the device can also adjust the length of the extension shaft on both sides of the roller by lengthening or shortening the third electric push rod, so that the device can adjust the detection range.

Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances. The following describes embodiments of the invention based on its overall structure.

[0024] Example 1: like Figures 1-15 As shown, this embodiment proposes a rapid track flatness detection device for a track inspection robot, including a housing 1. A travel reduction motor 2 is mounted on the housing 1, and a roller 3 is connected to the output shaft of the travel reduction motor 2. The travel reduction motor 2 drives the roller 3 to rotate, thereby driving the housing 1 to move on the ground track. A connecting plate 5 is slidably connected to the roller 3, and a stud 6 is rotatably mounted in the middle of the roller 3. The stud 6 and the connecting plate 5 are connected by a thread. A rotating plate 8 is rotatably connected to the connecting plate 5, and a connecting block 12 is rotatably connected to the connecting plate 5. A traction component 13 is mounted on the rotating plate 8. Subsequently, the stud 6 can be intermittently rotated by the traction component 13, thereby adjusting the distance between the connecting plate 5 and the roller 3 on the device to adapt to track widths and facilitate subsequent device assembly. The device is laterally suspended to accommodate the use of the suspension track. A slide cylinder 17 and a drive assembly 18 are mounted on the outer casing 1. A first electric push rod 20 is mounted on the slide cylinder 17. A linear displacement sensor 19 is mounted on the first electric push rod 20. A detection assembly 21 and a detection light 30 are provided on the linear displacement sensor 19. A switching assembly 26, an extension shaft 28, and a third electric push rod 29 are mounted on the detection assembly 21. The third electric push rod 29 is used to adjust the extension length of the extension shaft 28 on the detection assembly 21, thereby adjusting the detection range of the device. When the detection assembly 21 abuts against the track surface and moves relative to the track, if a protrusion or pit appears on the track surface, the linear displacement sensor 19 above the detection assembly 21 detects the displacement and illuminates the detection light 30, thereby realizing the flatness detection function.

[0025] The detection assembly 21 comprises a measuring rod 2101 installed on the linear displacement sensor 19, the bottom of the measuring rod 2101 is fixedly connected with a linear guide rail 2102, the linear guide rail 2102 is installed with a second electric push rod 2109, the second electric push rod 2109 is connected with an adjusting block 2103, the adjusting block 2103 is rotatably installed with a rotating shaft 2104, the rotating shaft 2104 is installed with a first connecting shell 2105 and a second connecting shell 2106 on both sides respectively, the first connecting shell 2105 is rotatably provided with a ball 2107, and the second connecting shell 2106 is rotatably provided with a roller 2108. The device can switch between long-distance rapid detection and local fine detection by rotating the rotating shaft 2104 and using the ball 2107 in the first connecting shell 2105 for detection or using the roller 2108 in the second connecting shell 2106 for detection. During detection, the second electric push rod 2109 can be elongated or shortened to drive the adjusting block 2103 to slide on the linear guide rail 2102, and the ball 2107 is driven by the linear guide rail 2102 to translate in the width direction of the track, so as to adjust the detection position of the device.

[0026] Embodiment 2: The scheme in embodiment 1 is further introduced in combination with a specific working mode, and details are described below: As shown in Figure 11 and Figure 12 , as a preferred embodiment, on the basis of the above mode, further, the guide block 4 is symmetrically installed on the roller 3, the guide block 4 penetrates into the adapter disc 5, the adapter disc 5 is rotatably connected with the rotating ring 7, the rotating ring 7 is fixedly connected with the rotating plate 8, the guide block 4 enables the adapter disc 5 to move straightly on the roller 3, and the rotating ring 7 ensures the stable rotation of the rotating plate 8 on the adapter disc 5.

[0027] As shown in Figure 8 and Figure 12 , as a preferred embodiment, on the basis of the above mode, further, the key groove 16 is formed in the stud 6, the spline block 15 is key-connected in the key groove 16, and the spline block 15 is fixedly connected with the rotating plate 8. When the rotating plate 8 rotates, the spline block 15 abuts against the inner wall of the key groove 16, and drives the stud 6 to rotate, so that the device can be adapted to the use of tracks with different widths in the subsequent process.

[0028] As shown in Figure 12As shown, in a preferred embodiment, based on the above method, a connecting cylinder 9 is further installed on the rotating plate 8, and a first locking block 10 is slidably installed inside the connecting cylinder 9. A docking groove 11 for docking with the first locking block 10 is opened on the connecting plate 5. A synchronous adjustment component 14 is installed between two adjacent rotating plates 8. When the first locking block 10 is located inside the docking groove 11, the distance between the connecting plate 5 and the roller 3 remains fixed. When the first locking block 10 is disengaged from the docking groove 11, the extension length of the connecting plate 5 can be adjusted to adapt to the use of tracks of different widths.

[0029] like Figure 11 and Figure 14 As shown, in a preferred embodiment, based on the above method, the connecting block 12 is further a spherical structure. The connecting blocks 12 are evenly distributed along the circumference of the connecting plate 5. The connecting blocks 12 can rotate on the connecting plate 5 without detaching from the connecting plate 5. This not only ensures that the device abuts against the left and right sides of the track, but also allows for detection in conjunction with the suspended track when the device is used in a lateral suspension.

[0030] like Figure 1 , Figure 2 and Figures 7-12 As shown, in a preferred embodiment, based on the above method, the traction assembly 13 further includes a traction steel rope 1301 fixedly connected to the first locking block 10, a first spring 1305 installed between the first locking block 10 and the rotating plate 8, a guide groove 1302 opened on the rotating plate 8, a connecting ring 1304 rotatably installed inside the rotating plate 8, and a traction plate 1303 fixedly connected to the connecting ring 1304. When the connecting ring 1304 rotates, it will pull the traction steel rope 1301. When the first locking block 10 is pulled by the traction steel rope 1301, the first locking block 10 will first disengage from the locking state, and then the pulling force of the traction steel rope 1301 will drive the rotating plate 8 to rotate. When the rotating plate 8 rotates, the first locking block 10 will gradually move to the next docking groove 11, so that the device realizes the locking and disengaging steps of the first locking block 10 through the rotation action, which enhances the convenience of device adjustment.

[0031] like Figure 1 , Figure 2 and Figure 7 As shown, in a preferred embodiment, based on the above method, the synchronous adjustment component 14 further includes a fixed block 1401 fixedly connected to the middle of the rotating plate 8. A synchronous wheel 1402 is rotatably mounted on the fixed block 1401, and a synchronous belt 1403 is installed between two adjacent synchronous wheels 1402. The synchronous wheel 1402 is fixedly connected to the connecting ring 1304. This device can rotate one of the synchronous wheels 1402, and drive the other synchronous wheel 1402 to rotate synchronously through the synchronous belt 1403, thereby synchronously adjusting the rotating plate 8 on the device, making it more convenient for the device to adapt to different width tracks for adjustment.

[0032] As Figures 1-3 shown, as a preferred embodiment, on the basis of the above-mentioned manner, further, the driving assembly 18 comprises a second motor 1804 fixedly connected to the shell 1, a screw rod 1803 fixedly connected to the output shaft of the second motor 1804, a threaded bushing 1802 threadedly connected to the outer side of the screw rod 1803, and a mounting block 1801 fixedly arranged on the side of the threaded bushing 1802. The mounting block 1801 is in sliding connection with the shell 1 and in fixed connection with the sliding cylinder 17. The second motor 1804 drives the screw rod 1803 to rotate, and the screw rod 1803 drives the threaded bushing 1802 and the mounting block 1801 to move, so that the device can perform static detection by moving the sliding cylinder 17 when the shell 1 is stationary.

[0033] As Figure 5 shown, as a preferred embodiment, on the basis of the above-mentioned manner, further, the adjusting block 2103 is provided with a clamping groove 23, and a second clamping block 24 is attached in the clamping groove 23. The bottom of the adjusting block 2103 is fixedly provided with a top block 22, and the two sides of the second clamping block 24 are provided with side plates 27. The side plates 27 are in fixed connection with the adjusting block 2103, and the second clamping block 24 is in sliding connection with the side plates 27. The top block 22 below the adjusting block 2103 can serve as a guide, so that the device can attach the ball 2107 to the track surface when the ball 2107 is used, and attach the roller 2108 to the track surface when the roller 2108 is used. The second clamping block 24 cooperates with the clamping groove 23 to enable the device to remain fixed after the ball 2107 is switched to the roller 2108, thereby ensuring the stability of the device in use. Figure 5 and Figure 6 As a preferred embodiment, on the basis of the above-mentioned manner, further, the second connecting shell 2106 is provided with a shaft sleeve 25, and the roller 2108 is in rotational connection with the shaft sleeve 25. A third electric push rod 29 is installed between the roller 2108 and the extension shaft 28. Since the roller 2108 can only detect its own length area, the third electric push rod 29 can be extended to increase the distance between the extension shaft 28 and the roller 2108, thereby adjusting the detection range of the device.

[0034] As Figure 5 ​As shown, as a preferred embodiment, on the basis of the above mode, further, the switching assembly 26 comprises a first limiting block 2601 fixedly connected to the second connecting shell 2106, a first tension spring 2602 installed between the rotating shaft 2104 and the first limiting block 2601, a first pressing block 2603 fixedly arranged at the bottom of the first limiting block 2601, a second limiting block 2604 fixedly arranged at the side of the first connecting shell 2105, a second tension spring 2605 installed between the rotating shaft 2104 and the second limiting block 2604, and a second pressing block 2606 fixedly arranged at the bottom of the second limiting block 2604. In combination Figure 5 and Figure 15 As can be seen, when the device is switched to precise detection, the top of the first connecting shell 2105 is pressed, so that the second limiting block 2604 moves downward, and the bottom of the second pressing block 2606 abuts against the inner wall of the rotating shaft 2104. Since the second connecting shell 2106 is not pressed, under the action of the first tension spring 2602, the first limiting block 2601 and the first pressing block 2603 are higher than the second limiting block 2604 and the second pressing block 2606. At this time, the device is in Figure 15 state, realizing the function of stable switching of flatness detection mode.

[0035] Embodiment 3: The schemes in Embodiment 1 and Embodiment 2 will be further introduced in combination with specific working modes, which are described in detail as follows: Specifically, the track flatness rapid detection device of the track inspection robot is used as follows: Figures 2-6 As shown, the walking reduction motor 2 on the shell 1 is used to drive the roller 3 to rotate, so as to drive the shell 1 to travel on the ground track. When the detection assembly 21 abuts against the track surface and moves relative to the track, and when the track surface has protrusions or pits, the linear displacement sensor 19 above the detection assembly 21 detects the displacement and makes the detection lamp 30 light up, realizing the track surface flatness detection function. When the device is used, the linear displacement sensor 19 can be kept stationary relative to the shell 1, and dynamic detection is performed by moving the shell 1, or the shell 1 is kept stationary, and static detection is performed by the driving assembly 18. Since the mounting block 1801 is slidingly connected to the shell 1 and fixedly connected to the sliding cylinder 17, the device can drive the screw rod 1803 to rotate by the second motor 1804, so that the screw rod 1803 drives the threaded bushing 1802 and the mounting block 1801 to slide on the shell 1, so that the device can move the sliding cylinder 17 when the shell 1 is stationary, and cooperate with the linear displacement sensor 19 and the detection assembly 21 to detect the flatness of the track surface. First, the initial position of the linear displacement sensor 19 and the detection assembly 21 in the sliding cylinder 17 is adjusted by the first electric push rod 20, so that the bottom of the ball 2107 abuts against the track surface, as shown in Figure 15As shown, at this time, the track surface flatness can be accurately detected by the ball 2107. When the ball 2107 moves to a convex or concave position, the ball 2107 is lifted or lowered, which will make the linear displacement sensor 19 transmit a signal to the detection lamp 30, so that the detection lamp 30 is lighted. During the detection, as shown in Figure 5 and Figure 6 , the device can detect by rotating the rotating shaft 2104, using the ball 2107 in the first connecting shell 2105 for detection or by the roller 2108 in the second connecting shell 2106 for detection, so that the device can be switched between long-distance fast detection and local fine detection. During the detection, the second electric push rod 2109 can be elongated or shortened to drive the adjusting block 2103 to slide on the linear guide rail 2102, and the ball 2107 and the roller 2108 are translated in the width direction of the track by the linear guide rail 2102, so as to adjust the detection position of the device. The third electric push rod 29 is elongated or shortened to change the distance between the roller 2108 and the extension shaft 28, so as to change the detection range of the device.

[0036] As shown in Figure 5 , when the device is switched from ball 2107 detection to roller 2108 detection, the second clamping block 24 is moved upward, the second clamping block 24 slides on the side plate 27, the second clamping block 24 is separated from the clamping groove 23, the rotating shaft 2104 is rotated by 180°, the top block 22 is gradually abutted with the second connecting shell 2106, the second connecting shell 2106 is moved downward after being pressed, the first tension spring 2602 is stretched, the first limiting block 2601 and the first pressing block 2603 are moved downward, the first pressing block 2603 abuts the inner wall of the rotating shaft 2104, the second tension spring 2605 drives the second limiting block 2604 and the second pressing block 2606 to reset without tension, at this time, the first connecting shell 2105 and the second connecting shell 2106 on the device are in Figure 5 opposite positions, which ensures that the roller 2108 and the ball 2107 are in a high-low position after the device switches the detection mode. As shown in Figure 13 and Figure 14 , the device can be adapted to the lateral suspension of the track for lateral suspension use. The ball structure of the originally used abutting block 12 can be used as a support and moving structure. According to the mode in Figure 13 , the outer shell 1 is pressed laterally, so that the outer shell 1 moves on the side of the suspension track, and then the first electric push rod 20 is adjusted to change the initial position of the measuring rod 2101 on the linear displacement sensor 19 and the detection assembly 21, so as to cooperate with the suspension track.

[0037] As shown in Figure 1 , Figure 2 and Figures 7-12As shown, the device can adjust its support range according to the width of the ground track or the height of the suspended track, rotate one side of the synchronous wheel 1402, and drive the other side of the synchronous wheel 1402 to rotate through the synchronous belt 1403. In combination with Figure 11 and Figure 12 As shown, since the synchronous wheel 1402 is fixedly connected with the adapter ring 1304, the synchronous wheel 1402 will first pull the traction steel rope 1301 through the traction plate 1303 on the adapter ring 1304 when rotating, the traction steel rope 1301 pulls the first clamping block 10 to make it disengage from the butt joint groove 11, when the rotating plate 8 disengages from the adapter disc 5, the traction steel rope 1301 in the guide groove 1302 acts on the rotating plate 8 to make the rotating plate 8 rotate, until the first clamping block 10 moves to the next butt joint groove 11. In this process, the spline block 15 rotates in the key groove 16 and drives the stud 6 to rotate, the stud 6 will drive the adapter disc 5 to slide under the guidance of the guide block 4 when rotating, so as to adjust the distance between the roller 3 and the adapter disc 5 to adapt to the use of tracks of different widths. When adjusting, the device only needs to rotate the synchronous wheel 1402 to realize the three steps of disengaging the adapter disc 5 from the roller 3, adjusting the distance between the adapter disc 5 and the roller 3, and re-engaging the adapter disc 5 and the roller 3, so that the device can accurately adjust and fix the distance between the adapter disc 5 and the roller 3 according to the width of the track.

[0038] The above is only the preferred specific embodiment of the present application, but the protection scope of the present application is not limited thereto, any person skilled in the art can make equivalent replacement or change according to the technical solution and the inventive concept of the present application within the technical range disclosed by the present application, which should be covered in the protection scope of the present application.
