Description

Technical Field

[0001] The utility model relates to the technical field of rail transportation, in particular to a track detection device for rail transportation. Background Art

[0002] During the use of urban rail transit, track detection devices need to be used regularly to detect track wear and dangerous locations, so as to facilitate timely processing and maintenance to prevent accidents. Track detection devices are equipment used to monitor and evaluate the condition of subway tracks. They can help operators detect track problems in a timely manner and carry out maintenance and repairs.

[0003] Reference can be made to the existing literature for a track detection device for rail transit (CN220243220U), which is provided with a driving structure, and a dual-axis motor drives the moving wheel to rotate at the upper end of the track, so that the moving frame at the upper end of the track can be automatically moved without the need for detection personnel to move. A structure for cleaning the track in the detection area is provided at the outer end of the power shaft of the moving wheel to avoid dust and mud adhering to the track on rainy days, which causes the camera equipment to detect unclearly, thereby achieving more accurate shooting and detection.

[0004] However, as shown in the reference, the cameras in the current track inspection vehicles are generally fixed at designated positions for shooting. In the reference, the cameras are set on both sides of the bottom. When the inspection staff needs a close-up or long-range view of the designated position, this fixed design is difficult to meet different shooting needs. At the same time, when the device is used outdoors, due to the high reflectivity of the rails, it is easy to overexpose the shooting under high sunlight conditions, affecting the image quality.

The utility model sets a lateral displacement mechanism and a longitudinal displacement mechanism, so that the lateral position and the longitudinal position of the track detection camera can be quickly adjusted during shooting, and the designated position of the track can be shot according to the needs, which is more flexible to use. At the same time, during outdoor use, the sunshade mechanism can reduce the impact of reflection and improve the imaging quality.

The automated control is easy to operate and more flexible to use.

When the device is used outdoors, the sunshade mechanism can be driven to move backward by the hydraulic rod, and then the shielding position can be adjusted according to the direction of sunlight.

[0026] Reference Figure 1-4 A track detection device for rail transit comprises: a detection vehicle body 1, a lateral displacement mechanism and a longitudinal displacement mechanism are arranged at the rear of the detection vehicle body 1, and the longitudinal displacement mechanism is provided with two groups and both are connected to the rear side of the lateral displacement mechanism; the detection vehicle body 1 is fixedly installed with two slide rails 2 at the upper end, and the inside of the slide rails 2 are fixedly installed with hydraulic rods 18 and the telescopic parts of the hydraulic rods 18 are connected to sliders 19, and the upper part of the sliders 19 is connected with a sunshade mechanism, and the sunshade mechanism includes three sunshades, namely a first baffle 5, a second baffle 7 and a third baffle 9, and the lateral displacement mechanism is fixed at the rear of the detection vehicle body 1 The side is used for lateral adjustment and also carries the longitudinal displacement mechanism. The design of the lateral displacement mechanism and the longitudinal displacement mechanism makes the lateral position and longitudinal height of the track detection camera 16 adjustable. The operation of the hydraulic rod 18 can drive the slider 19 to move in a straight line, so that the slider 19 can move within the stroke of the slide rail 2. The slider 19 is connected to the sunshade mechanism, so that the hydraulic rod 18 can drive the entire sunshade mechanism to move in a straight line through the slider 19. When the sunshade mechanism is not needed, the sunshade mechanism can be moved forward to directly above the inspection vehicle body 1, and the sunshade mechanism can be retracted to the shooting position when it is needed.

[0027] Specifically, the lateral displacement mechanism mainly includes a lateral displacement track 3, a first servo motor 10, a bidirectional screw 11 and a first threaded sleeve 12, and the lateral displacement track 3 is fixed on the rear surface of the inspection vehicle body 1;

[0028] Furthermore, the first servo motor 10 is fixed at one end of the lateral displacement track 3, the driving shaft of the first servo motor 10 is connected to the bidirectional screw 11 and the bidirectional screw 11 rotates on the inner side of the lateral displacement track 3, and the outer side of the bidirectional screw 11 is threadedly connected with two first threaded sleeves 12. After the first servo motor 10 is operated as a driving source, it can drive the bidirectional screw 11 to rotate, so that the two first threaded sleeves 12 threadedly connected to the outer side of the bidirectional screw 11 move in the opposite direction, thereby driving the longitudinal displacement track 4 connected thereto to move in the opposite direction, thereby adjusting the lateral position.

[0029] In this embodiment, the longitudinal displacement mechanism includes: a longitudinal displacement track 4, a second servo motor 13, a one-way screw 14 and a second threaded sleeve 15, and the longitudinal displacement track 4 is fixed to the rear side of the two first threaded sleeves 12 respectively;

[0030] Furthermore, the second servo motors 13 are fixedly installed on the upper end of the longitudinal displacement track 4, the driving shaft of the second servo motor 13 is connected to the one-way screw 14 and the outer side of the one-way screw 14 is threadedly connected to the second threaded sleeve 15. The operation of the second servo motor 13 can drive the one-way screw 14 to rotate, so that the second threaded sleeve 15 threadedly connected to the outer side of the one-way screw 14 moves longitudinally in a straight line, thereby driving the track detection camera 16 connected thereto to move synchronously.

[0031] Specifically, Figure 3 As shown, a track detection camera 16 with a shooting direction facing downward is fixedly provided on the rear side of the second threaded sleeve 15, and a fill light 17 is connected to one end of the track detection camera 16 with the lighting direction facing downward. A data transmission module is installed inside the track detection camera 16, which is responsible for transmitting the high-definition video images captured by the camera and any possible abnormal data, such as cracks, wear marks or the presence of foreign objects, to the central control unit or the remote monitoring center in real time and efficiently, so as to ensure the timeliness and accuracy of the monitoring data even in a complex and changeable on-site environment. The fill light 17 not only provides necessary lighting, but also enhances the shooting effect of the track detection camera 16 at night or under low light conditions, and is also equipped with components such as photosensitive sensors to realize automatic brightness adjustment through an intelligent sensing system, so as to ensure the clarity of the captured picture and avoid the glare problem that may be caused by excessive lighting, thereby further improving the overall performance and user experience of the detection system.

[0032] Furthermore, a first motor 6 is fixed to one end of the first baffle 5, and the first motor 6 drives the second baffle 7 to rotate through a transmission shaft. The second baffle 7 can be flipped 90° to shield the rear side. Two second motors 8 are fixed to the rear side of the second baffle 7, and the two second motors 8 drive the third baffle 9 to rotate through a transmission shaft. The third baffle 9 can be rotated 90° to shield both sides, so that the shielding position can be adjusted according to the direction of sunlight, thereby improving the flexibility of use.

[0033] Working principle: When using the utility model, if the detection personnel need to take a close-up or long-range shot of a designated position during the use of the device, the position point can be reached through the lateral displacement mechanism, and then the shooting height can be adjusted through the longitudinal displacement mechanism. After the first servo motor 10 is operated as a driving source, it can drive the bidirectional screw 11 to rotate, so that the two first threaded sleeves 12 threadedly connected to the outside of the bidirectional screw 11 move in the opposite direction, thereby driving the longitudinal displacement track 4 connected thereto to move in the opposite direction, thereby adjusting the lateral position. The operation of the second servo motor 13 can drive the unidirectional screw 14 to rotate, so that the second threaded sleeve 15 threadedly connected to the outside of the unidirectional screw 14 moves in a longitudinal straight line, thereby driving the track detection camera 16 connected thereto to move synchronously. When the device is used outdoors, the sunshade mechanism can be driven to move to the rear side through the hydraulic rod 18, and then the shielding position can be adjusted according to the direction of sunlight. The second baffle 7 and the third baffle 9 can both be adjusted at an angle to complete the flipping, so that the sunshade mechanism can effectively reduce the impact of reflections and improve imaging quality.

[0034] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
