Description

Technical Field

[0001] The present invention relates to the technical field of railway track detection, and in particular to a ballast track bed section scanning track trolley. Background Art

[0002] The characteristic values of the track bed section are the main basis for evaluating the condition of the track bed, providing some maintenance and repair decisions, guiding some on-site operations, and evaluating the working quality of the track bed. After the maintenance operations of the ballast track line (especially the lifting and leveling renovation), problems such as ballast slumping and insufficient ballast volume will occur, resulting in poor track bed conditions. For example, the slope of the track bed side slope is too steep, the height of the ballast shoulder pile is too small, and the width of the track bed top surface is insufficient. This may cause a reduction in the lateral resistance of the track bed, prone to rail buckling and runway, endangering the safety of train operation. In the existing technology, the characteristic values of the track bed section (track bed thickness, top surface width, side slope gradient, ballast profit and loss) mainly rely on technicians to measure using tape measures, level gauges, total stations, etc.

[0003] There are mainly three problems with such traditional detection tools:

[0004] First, manual inspection can only sample the track bed section by experience, that is, manually observe the ballast missing situation with the naked eye and then measure, and it is impossible to conduct a general survey of the dimensions of the entire track bed section.

[0005] Second, the detection accuracy is low, the efficiency is low, the track bed section cannot be accurately and quickly detected, the requirements for the detection personnel are relatively high, and it mostly depends on human experience.

[0006] Third, due to the need to perform operations on the track, restricted by the skylight time, the effective operation time is short, and it cannot meet the needs of the line general survey.

[0007] Therefore, relying on the traditional detection and maintenance methods can no longer meet the actual needs, and there is an urgent need for a trolley dedicated to scanning the track bed section to quickly evaluate the condition of the ballast track bed section. Summary of the Invention

[0051] In addition, the terms "first" and "second" are only used for descriptive purposes and cannot be understood as indicating or implying relative importance or implicitly specifying the quantity of the indicated technical features. Thus, the features defined with "first" and "second" may explicitly or implicitly include at least one of such features. In the description of the present invention, the meaning of "several" is at least two, such as two, three, etc., unless otherwise specifically defined.

[0052] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments:

[0053] As shown in Figure 1 , 2 , and Figure 3, a ballast track bed cross-section scanning track trolley includes a traveling mechanism 2 driven by a driving motor 3 provided at the bottom of the trolley, a bogie 1 provided at the upper end of the traveling mechanism 2, a vertical rod 7 provided at the upper part of the bogie 1, a scanning and photographing device 6 provided at the top end of the vertical rod 7, a control mechanism 8 for adjusting the angle of the vertical rod 7, a support rod 9 provided between the bogie 1 and the vertical rod 7, a distribution box 4 provided at a corner of the bogie 1, a computer 5 provided at the upper end of the distribution box 4, a remote controller, and several cables; the vertical rod 7 is hinged to the upper end of the bogie 1; the control mechanism 8 fixes the vertical rod 7 and can finely adjust the vertical rod 7 in the pitch direction, left and right directions, and rotation direction; when the traveling mechanism 2 travels on the ballast track, the scanning and photographing device 6 scans and photographs the cross-section of the ballast track bed; the remote controller controls the forward, backward, and braking of the trolley. The remote controller and the trolley are provided with wireless communication.

[0054] Further, as shown in Figure 3 , the traveling mechanism 2 includes a driving shaft 2-1 installed with a driving motor 3, an intermediate shaft 2-3 connected to the driving shaft 2-1 through a first bevel gear set 2-4, a driven shaft 2-2 connected to the intermediate shaft 2-3 through a second bevel gear set 2-5, and four wheels respectively provided on both sides of the driving shaft 2-1 and the driven shaft 2-2; the driving shaft 2-1 and the driven shaft 2-2 are arranged in parallel, and the intermediate shaft 2-3 is arranged perpendicular to both the driving shaft 2-1 and the driven shaft 2-2; the intermediate shaft 2-3 is installed on one side of the right longitudinal beam 1-4 through a first bearing seat and a second bearing seat; the driving motor 3 is fixedly installed on one side of the rear cross beam 1-2; the driving motor 3 is a brushless DC reduction motor. The driving motor 3 is provided on one side of the rear cross beam 1-2 and is located at the rear of the traveling mechanism 2 to control the traveling speed of the trolley on the track.

[0055] Further, as shown in Figure 3As shown in the figure, the first bevel gear set 2-4 includes a first bevel gear disposed on the drive shaft 2-1 and a second bevel gear disposed on the intermediate shaft 2-3 and meshing with the first bevel gear; the second bevel gear set 2-5 includes a third bevel gear disposed on the intermediate shaft 2-3 and a fourth bevel gear disposed on the driven shaft 2-2 and meshing with the third bevel gear. After the drive motor 3 is started, the drive shaft 2-1 rotates, and the two wheels connected to the drive shaft 2-1 move. An intermediate shaft 2-3 is provided on the right side of the trolley (near the right longitudinal beam 1-4). There are two bevel gears (the first bevel gear set 2-4) between the drive shaft 2-1 and the intermediate shaft 2-3. The rotation of the drive shaft 2-1 drives the rotation of the intermediate shaft 2-3. The bevel gears (the second bevel gear set 2-5) at the connection between the intermediate shaft 2-3 and the driven shaft 2-2 cause the driven shaft 2-2 to rotate, thereby driving the wheels to move. Thus, the trolley travels on the track.

[0056] Further, the wheel cover of the wheel is made of POM material. The wheel cover of the wheel made of POM material has high stiffness and strength, good elasticity, good anti-friction and wear-resistant performance; good insulation performance, hardly affected by temperature and humidity; can maintain considerable chemical stability at high temperatures and has good dimensional stability.

[0057] Further, as Figures 1-3 shown in the figure, the bogie 1 is a welded box girder structure with the same front and rear structures, coplanar mounting surfaces, and is a two-axle bogie; the bogie 1 includes a front cross beam 1-1, a rear cross beam 1-2, a left longitudinal beam 1-3 and a right longitudinal beam 1-4; the bottom of the support rod 9 is installed in the middle of the rear cross beam 1-2 through a first locking clip, and the upper end of the support rod 9 is connected to the vertical rod 7 through a second locking clip; the control mechanism 8 is located in the middle of the front cross beam 1-1. The support rod 9 is an inclined support rod to assist in supporting the bogie 1. Setting the bottom of the support rod 9 in the middle of the rear cross beam 1-2 is beneficial to increasing the stability of the entire device.

[0058] Further, the front cross beam 1-1, the rear cross beam 1-2, the left longitudinal beam 1-3 and the right longitudinal beam 1-4 are all made of rectangular hollow bars; the vertical rod 7 and the support rod 9 are both made of circular hollow bars. Under the same conditions, the torsional stiffness of a circular or annular cross-section is higher and the bending stiffness is lower. Therefore, rectangular bars are more suitable for making cross beams, and circular bars are more suitable for making vertical rods. In order to adapt to the complex environment of the railway site, in this embodiment, the cross beams (the front cross beam 1-1, the rear cross beam 1-2, the left longitudinal beam 1-3 and the right longitudinal beam 1-4) and the vertical rods (including the vertical rod 7 and the support rod 9) are all made of hollow bars with a thickness of about 3 mm, and the material is selected as aluminum profile. Cross beam insulating sleeves, cross beam fastening inner pins and cross beam insulating pads are provided at the connections between the cross beams and the longitudinal beams to ensure the stable firmness of the bogie 1.

[0059] Specifically, the ballast track bed section scanning track trolley travels on a railway with a standard gauge of 1435 mm. Considering the overall stability of the track trolley, the size parameters of the cross beams (front cross beam 1-1 and rear cross beam 1-2) are initially determined to be 60×60×1600 mm. The scanner 6-1 is located at the top of the vertical rod 7. The height of the vertical rod 7 is based on the principle that "the scanner can completely scan the entire ballast bed and maintain a safe distance from the overhead catenary above". It is stipulated that the height difference between the top surface of the track trolley and the top surface of the rail is at most 2 m. By formulating the sizes of multiple vertical rods 7 and using Abaqus for simulation, the top offset amounts of the trolley are analyzed under three conditions: ① static track irregularity; ② rail chunk shedding, causing the trolley to jolt and the lidar to vibrate laterally; ③ lateral acceleration at the top of the vertical rod. The simulation results show that when the size of the vertical rod 7 is Φ38×1780 mm, the stability is the best, and the maximum offset amount at this time is 2.7472 mm. On-site tests are conducted using a high-speed camera, and the maximum offset amount generated at the top of the device is 2.5 mm. The impact of this offset amount on the scanning results is relatively small and can be ignored. The inclinometer 4-1 is located at the bottom of the bogie 1 with the smallest vibration displacement. To ensure the service life of the wires of the scanner 6-1 and the camera 6-2, the data cables connecting the scanner 6-1, the camera 6-2, and the computer 5 and the wires connected to the power supply are placed in the hollow vertical rod of the vertical rod 7.

[0060] Further, as Figure 3 shown, an inclinometer 4-1 for discriminating the type of line and the superelevation value of the outer rail in the curve section, a first battery 4-2 and a second battery 4-3 for powering the inclinometer 4-1 and the scanning and photographing device 6 are provided in the distribution box 4; a computer clip for fixing the computer 5 is installed at the upper end of the distribution box 4.

[0061] Specifically, the distribution box 4 is located at the angle between the front cross beam 1-1 and the left longitudinal beam 1-3. The inclinometer 4-1 is connected to the computer 5 through a data cable and connected to the power supply (the first battery 4-2 and the second battery 4-3) through a wire, and is used to discriminate the type of line (straight section or curve section) and the superelevation value of the outer rail in the curve section. The drive motor 3 serves as the power for the trolley to move forward, and the power supply powers the inclinometer 4-1, the scanner 6-1, and the camera 6-2. A computer clip is installed on the distribution box 4 to fix the computer 5. The scanner 6-1 and the camera 6-2 are both connected to the computer 5 through data cables and connected to the power supply (the first battery 4-2 and the second battery 4-3) through wires.

[0062] Further, as Figure 1 、 2As shown, the scanning and photographing device 6 includes a scanner 6-1 capable of scanning the cross-sectional dimensions of the entire track bed and a camera 6-2 capable of photographing the entire track bed; the scanner 6-1 and the camera 6-2 are fixedly installed at the top of the vertical pole 7 through a mounting bracket 6-3; the scanner 6-1 is a lidar scanner, specifically a two-dimensional lidar scanner is used in the present invention.

[0063] To ensure the accuracy of scanning and photographing, the scanner 6-1 and the camera 6-2 should be placed "correctly". For this purpose, markings are engraved in advance at the positions where the scanner 6-1 and the camera 6-2 are placed on the vertical pole 7 (in the present invention, a mounting bracket 6-3 is specially made, as Figure 9 , 10 , 11 shown), and during installation, it is directly installed at the corresponding positions.

[0064] Furthermore, as Figure 12 shown, the scanning and photographing device 6 is installed at the top of the vertical pole 7. The bottom of the vertical pole 7 is a lower joint for fixing the vertical pole 7 and adjusting the angle of the vertical pole 7, and holes for cables to pass through and several mounting holes are provided on the lower joint; the mounting holes are used for installing the vertical pole pitch rotation shaft 8-5, the vertical pole pitch adjustment shaft 8-6, the vertical pole pitch locking rod 8-7, the vertical pole pitch push shaft 8-8, the vertical pole rotation shaft 8-13, etc.

[0065] Furthermore, the control mechanism 8 includes the lower joint of the vertical pole 7, the vertical pole fixing disk locking device 8-1, the vertical pole fixing disk 8-2, the first rotation and pitch disk locking device 8-3, the rotation and pitch disk 8-4, the vertical pole pitch rotation shaft 8-5, the vertical pole pitch adjustment shaft 8-6, the vertical pole pitch locking rod 8-7, the vertical pole pitch push shaft 8-8, the vertical pole lateral swing adjustment sleeve 8-9, the vertical pole rotation adjustment fixed upper seat 8-10, the vertical pole rotation adjustment fixed lower seat 8-11, the second rotation and pitch disk locking device 8-12 and the vertical pole rotation shaft 8-13; (here, for the convenience of expression, the vertical pole fixing disk locking device 8-1 and the vertical pole fixing disk 8-2 are included in the control mechanism 8).

[0066] The vertical pole fixing disk 8-2 is fixedly installed in the middle of the rear cross beam 1-2 through the vertical pole fixing disk locking device 8-1 and the cross beam fastening hand wheel; the vertical pole fixing disk locking device 8-1 includes a vertical pole fixing disk locking head, a vertical pole fixing disk locking shaft and a vertical pole fixing disk positioning sleeve;

[0067] The rotary pitching disc 8-4 includes a rotary pitching disc bottom plate, a first rotary pitching disc vertical plate and a second rotary pitching disc vertical plate that are parallel and perpendicular to the rotary pitching disc bottom plate; it is connected to the vertical rod fixing disc 8-2 and the front cross beam 1-1 through two cross beam fastening handwheels and the first rotary pitching disc locking device 8-3 and the second rotary pitching disc locking device 8-12; the first rotary pitching disc locking device 8-3 and the second rotary pitching disc locking device 8-12 have the same structure, and both include a vertical rod rotary disc locking seat and a vertical rod rotary disc locking shaft;

[0068] The lower joint of the vertical rod 7 is installed between the first rotary pitching disc vertical plate and the second rotary pitching disc vertical plate, and the bottom end of the lower joint of the vertical rod 7 is hinged to the upper surface of the front cross beam 1-1 through the vertical rod rotary shaft 8-13;

[0069] The attitude adjustment of the vertical rod 7 for pitching rotation is carried out through the vertical rod pitching rotating shaft 8-5, the vertical rod pitching adjusting shaft 8-6, the vertical rod pitching pushing shaft 8-8 and the vertical rod pitching locking rod 8-7 to achieve the purpose of fastening the vertical rod 7, locking in place and ensuring normal operation;

[0070] The left and right position adjustment of the upper top end of the vertical rod 7 is carried out through the vertical rod lateral swing adjustment sleeve 8-9; and the vertical rod 7 is fixed through the vertical rod rotary adjustment fixed upper seat 8-9 and the vertical rod rotary adjustment fixed lower seat 8-10; the vertical rod lateral swing adjustment sleeve 8-9 is connected to the vertical rod rotary adjustment fixed upper seat 8-9.

[0071] The rotation direction of the rotary pitching disc bottom plate of the rotary pitching disc 8-4 is adjusted through the rotation handles of the first rotary pitching disc locking device 8-3 and the second rotary pitching disc locking device 8-12, so as to finely adjust the rotation direction of the vertical rod 7.

[0072] Specifically, as Figure 4 shown, the lower joint of the vertical rod 7 and the rotary pitching disc 8-4 constitute the control mechanism 8 of the trolley. The vertical rod fixing disc 8-2 and the front cross beam 1-1 are tightly connected together through the vertical rod fixing disc locking head and the cross beam fastening handwheel, with the vertical rod fixing disc locking shaft and the vertical rod fixing disc positioning sleeve attached in the middle. The vertical rod fixing disc 8-2 is as Figure 5 shown; the rotary pitching disc 8-4 includes a first rotary pitching disc vertical plate, a second rotary pitching disc vertical plate and a rotary pitching disc bottom plate, all of which are provided with adapted mounting holes and arc adjustment holes, etc., as Figure 6 、 7 、8 shown; it is connected to the vertical rod fixing disc 8-2 and the front cross beam 1-1 through the cross beam fastening handwheel and the vertical rod rotary disc locking seat (the first rotary pitching disc locking device 8-3 and the second rotary pitching disc locking device 8-12, symmetrically arranged on both sides of the rotary pitching disc 8-4);

[0073] The attitude adjustment of pitching and rotation of the device is carried out through the vertical pole pitching rotating shaft 8-5, the vertical pole pitching adjusting shaft 8-6, the vertical pole pitching pushing shaft 8-8 and the vertical pole pitching locking rod 8-7 to achieve the purpose of fastening the vertical pole 7, locking in place and ensuring normal operation.

[0074] The pitching direction of the vertical pole 7 can be adjusted by loosening and tightening the vertical pole pitching locking rod 8-7. The second locking clip at the connection between the inclined support 9 and the vertical pole 7 can also adjust the pitching direction of the vertical pole 7, while ensuring the stability of the locking direction. The left and right positions of the upper end of the vertical pole 7 are adjusted through the vertical pole lateral swing adjusting sleeve 8-9; by rotating the crossbeam fastening handwheel handle (rotating the positions of the two slots in the top view of the pitching disc 8-4), the bottom plate of the rotating pitching disc 8-4 is rotated, thereby twisting the vertical pole 7.

[0075] By finely adjusting the pitching direction, left and right direction and rotating direction of the vertical pole 7, the direction deviation of the scanner 6-1 and the camera 9-2 is reduced, thereby improving the accuracy of the scanner 6-1 and the camera 6-2.

[0076] Furthermore, for the convenience of on-site detection by the operator carrying the trolley, straps are also provided at the crossbeams (front crossbeam 1-1 and rear crossbeam 1-2) where the installation control mechanism 8 and the support rod 9 are installed. The installation position and installation length (adjustable) of the straps should be convenient for carrying the trolley on the back.

[0077] Usage method:

[0078] Place the computer 5 on the distribution box 4 and fix it with a computer clip. The scanner 6-1 and the camera 6-2 are fixed on the mounting bracket 6-3, and the special wires for the scanner and the special wires for the camera are connected. The other ends of the wires are connected to the computer 5. After connecting the lines, turn on the power and debug the computer 5 for testing. After testing, first disconnect the power supply, and then remove the scanner 6-1 and the camera 6-2.

[0079] When the trolley travels along the line direction on the track, the top scanner 6-1 will continuously scan the roadbed. The entire scanned track presents a spiral scan pattern. See the Figure 13 for the spiral model of the track top view. In the figure, the block diagram represents the sleeper; the vertical line represents the line connected by two steel wires as laser scanning points, and the horizontal line represents the top view of the entire roadbed section scanned by the scanner 6-2 (lidar). See the Figure 14 for the front view when the trolley scans. The trajectory of the scanning points of the scanner 6-2 (lidar) is spiral, and the points of the entire roadbed section are not on the same cross-section.
