Description

Technical Field

[0001] The utility model relates to the technical field of railway track identification and measurement, in particular to a railway track detection device based on laser scanning. Background Art

[0002] In recent years, with the large-scale infrastructure construction in my country, the transportation demand for bulk goods such as energy and ore has surged, and my country's railway freight volume has continued to grow steadily. In order to meet the ever-expanding freight demand, my country has actively promoted the construction of heavy-duty railways. At the same time, since the freight volume is concentrated on a few heavy-duty railways, heavy-duty railways are subject to extremely high transportation density, resulting in a high probability of abnormal railway tracks on these railway lines. The safety of heavy-duty railway tracks is directly related to the transportation of important materials and the economic benefits of bulk freight.

[0003] At present, there is a serious imbalance between the means of detecting track anomalies and the transportation intensity of heavy-haul railways. It mainly relies on simple manual inspections, and large-scale, dynamic track anomaly detection can only rely on periodic track inspection vehicle inspections. At the same time, the inspection results of track inspection vehicles still need to be manually reviewed, and there is a lack of direct three-dimensional measurement methods. These obvious contradictions and shortcomings urgently need to be compensated by modern machine vision and detection technology to ensure the safe and efficient operation of heavy-haul railways.

[0004] However, most existing track inspection equipment can only detect and measure one of the components related to rails, fasteners, and track plates, and has a single function. In addition, there are problems such as inconvenience and low efficiency in manual movement. The maintenance status of heavy-duty railway tracks is poor, and when the equipment is running quickly and automatically for inspection, it is easy to derail and have poor inspection results.

For ordinary technicians in this field, the specific meanings of the above terms can be understood according to specific circumstances.

[0027] In one embodiment, Figure 1 and Figure 2 As shown, a railway track detection device 10 based on laser scanning includes a main body 100, two main body brackets 200, a driving wheel assembly 300, a driven wheel assembly 400, an elastic limiting assembly 500, a support rod 600 and a laser scanner 700;

[0029] The driving wheel assembly 300 is arranged on one of the main body brackets 200, the driven wheel assembly 400 is arranged on another of the main body brackets 200, and the driving wheel assembly 300 is electrically connected to the control module; the elastic limiting assembly 500 is arranged on the main body 100, and the elastic limiting assembly 500 is used to clamp the main body 100 on the railway track 900; the support rod 600 is arranged on the main body 100, and the laser scanner 700 is arranged on one end of the support rod 600 away from the main body 100, and the laser scanner 700 is electrically connected to the control module.

[0030] Specifically, a data processing module is also provided in the main body, and the data processing module is electrically connected to the control module and the laser scanner respectively; the data processing module is used to analyze and process the data information obtained by the laser scanner. When the railway track detection device 10 based on laser scanning is working, the control module will control the driving wheel assembly 300 to work, that is, the wheels in the driving wheel assembly 300 rotate, which will drive the wheels in the driven wheel assembly 400 to rotate, and the wheels in the driving wheel assembly 300 and the wheels of the driven wheel assembly 400 roll on the railway track 900; thereby, the railway track detection device 10 based on laser scanning moves on the railway track 900. At the same time, the control module controls the laser scanner 700 to scan the railway track 900, and the scanned information will be sent to the data processing module for analysis and processing. The elastic limit assembly 500 is used to slide the laser scanning-based railway track detection device 10 on the railway track 900 by means of a spring elastic fixed clamping method, so as to prevent the laser scanning-based railway track detection device 10 from being offset when moving on the railway track 900. The power module is used to supply power to the control module, the data processing module, the driving wheel assembly 300 and the laser scanner 700.

[0031] In order to more firmly fix the main body 100 on the rails for movement, in one embodiment, Figure 1 and Figure 2 As shown, the elastic limiting assembly 500 includes a first limiting assembly 510 and a second limiting assembly 520; the first limiting assembly 510 and the second limiting assembly 520 are respectively arranged at positions of the main body 100 close to the two main body brackets 200, the first limiting assembly 510 is used to abut against one railway track 900, and the second limiting assembly 520 is used to clamp and fix another railway track 900. Specifically, the first limiting assembly 510 has a spring 515, and the clamping force of the elastic limiting assembly 500 can be adjusted by adjusting the elastic force of the spring 515 in the first limiting assembly 510. The second limiting assembly 520 is used to clamp the railway track 900 to prevent the railway track detection device 10 based on laser scanning from deviating when it slides on the railway track 900.

[0032] In order to adjust the elastic force of the first limiting component 510, in one embodiment, Figure 3As shown, the first limiting assembly 510 includes a first limiting wheel 511, a first wheel frame 512, a first connecting frame 513, a guide column 514 and a spring 515; the first connecting frame 513 is connected to the main body 100, and a connecting hole is opened on the first connecting frame 513, the guide column 514 passes through the connecting hole, and both ends of the guide column 514 are located outside the connecting hole, one end of the guide column 514 is connected to the first wheel frame 512, the other end of the guide column 514 is provided with a thread, and the threaded end of the guide column 514 is screwed with a nut, and the nut abuts against a side of the first connecting frame 513 facing away from the first wheel frame 512, the first limiting wheel 511 is rotatably set on the first wheel frame 512, the spring 515 is set on the guide column 514, one end of the spring 515 abuts against the first wheel frame 512, and the other end of the spring 515 abuts against the first connecting frame 513.

[0033] Specifically, the first limiting wheel 511 is rollingly arranged on the inner side of a railway track 900. By adjusting the positional relationship between the guide column 514 and the first connecting frame 513, the size of the spring 515 compressed by the first connecting frame 513 can be adjusted, that is, the size of the compression elastic force of the spring 515 can be adjusted, so that the size of the clamping force of the elastic limiting assembly 500 can be adjusted. According to actual needs, the size of the clamping force of the elastic limiting assembly 500 can be adjusted to allow the railway track detection device 10 based on laser scanning to be clamped and fixed on the railway track 900 more firmly.

[0034] In order to enable the second limiting assembly 520 to clamp the railway track 900 and move, in one embodiment, Figure 4As shown, the second limiting assembly 520 includes at least two second limiting wheels 521, two second wheel frames 522 and a second connecting frame 523; one end of the second connecting frame 523 is connected to the two second wheel frames 522, and the other end of the second connecting frame 523 is connected to the main body 100, and the two second connecting frames 523 are arranged at intervals, and at least one second limiting wheel 521 is rotatably arranged on each second wheel frame 522.

Specifically, the wheel hub 360 is used to roll on the railway track 900. When the railway track detection device 10 based on laser scanning is working, the control module will control the motor 380 to work, thereby driving the connecting shaft 310 to rotate, and the rotation of the connecting shaft 310 will drive the wheel hub 360 to roll on the railway track 900, so that the railway track detection device 10 based on laser scanning can be moved on the railway track 900.

[0036] In order to fix the connecting shaft 310 in the mounting seat 320 for rotation, in one embodiment, as shown in FIG.

The sleeve 340 is disposed in the middle part of the mounting seat 320. The sleeve 340 is used to fix the connecting shaft 310 in the mounting seat 320 for rotation, so as to prevent the connecting shaft 310 from deviating during rotation.

[0037] In order to reduce the rotational friction of the connecting shaft 310, in one embodiment, Figure 6As shown, the driving wheel assembly 300 also includes a bearing 330 and two end covers 370.

Specifically, the receiving hole 321 provided on the mounting seat 320 is used to place the bearing 330. The two end covers 370 are used to fix the bearing 330 in the receiving hole 321. The two end covers 370 also protect the bearing 330. By arranging the bearing 330 on the connecting shaft 310, the friction force when the connecting shaft 310 rotates can be reduced. At the same time, after the wheel hub 360 is disassembled from the mounting seat 320 , the end cover 370 is opened, and the bearing 330 can be replaced or maintained.
