Description

Technical Field

[0001] This utility model relates to the field of track flaw detection technology, and in particular to a detachable track flaw detection chassis structure and track flaw detection equipment. Background Technology

[0002] Rail transit: Urban rail transit is defined as a general term for rapid, high-capacity public transportation that is usually powered by electricity and uses wheel-rail transportation. It generally includes subways, light rail, and modern trams. Urban rail transit refers to public transportation facilities with fixed lines, fixed tracks, and equipped with transport vehicles and service facilities.

[0003] Railcars travel on tracks. To ensure railway transportation safety, rail transit personnel often need to conduct regular inspections and maintenance of railway lines. In addition, they also need to periodically perform track flaw detection operations, which require various precision instruments and equipment, such as track inspection instruments, flaw detectors, catenary inspection instruments, and signal analyzers. To improve the stability and accuracy of these precision instruments on the track, they are usually mounted on a track flaw detection chassis. The chassis slides on the track to move the various precision instruments, thereby completing the functions of measuring and flaw detection.

[0004] Because of the long distance between the two tracks, the track inspection chassis that slides on the tracks is large and heavy. It requires the cooperation of multiple workers to move it onto the tracks, making it only suitable for situations with many workers, thus limiting its application. It also requires a large amount of space for storage. In addition, since there are three types of railway gauges—standard gauge, narrow gauge, and wide gauge—the distance between the gauges also varies. The width of the existing track inspection chassis is fixed, meaning it can only work on one of the fixed gauges and cannot be flexibly adjusted according to different gauges, further limiting its application. Utility Model Content

[0005] This utility model aims to at least partially solve one of the technical problems in related technologies. To this end, this utility model proposes a detachable track flaw detection chassis structure and a track flaw detection device.

[0006] The technical solution to the technical problem solved by this utility model is as follows:

[0007] This utility model proposes a detachable track flaw detection chassis structure, including a transverse frame, with slidable mounting blocks at both ends of the transverse frame, and an adjustment component for adjusting the sliding distance between the mounting blocks and the transverse frame; a longitudinal frame, which has a T-shaped structure, is connected to the outside of the mounting blocks and is connected to them by a quick-release component; and a travel wheel and a guide wheel are respectively set at the bottom of the longitudinal frame.

[0008] Preferably, the end of the transverse frame is provided with a first slot, and the inner side of the mounting block is connected to a first plug that is adapted to be inserted into the first slot; guide grooves are provided on both sides of the transverse frame, and an elastic guide block is connected to the outer wall of the first plug, and the pressing guide block can slide along the guide groove.

[0009] Preferably, the adjustment assembly includes a first connecting seat and a second connecting seat fixed to the transverse frame and the mounting block respectively. A forward threaded rod and a reverse threaded rod are fixed to the inner sides of the first connecting seat and the second connecting seat 1102 respectively. A bidirectional threaded sleeve is fitted on both the forward threaded rod and the reverse threaded rod, and two locking nuts are fitted on the outer side of the bidirectional threaded sleeve.

[0010] Preferably, a second groove is provided on one end of the longitudinal frame and near the mounting block, and a second protrusion that mates with the second groove is fixedly provided on the side of the mounting block away from the first protrusion.

[0011] Preferably, the quick-installation assembly includes T-shaped grooves formed on the two side walls of the mounting block and the two side walls of the longitudinal frame, with H-shaped quick-installation blocks embedded in the two T-shaped grooves. A first fixing shaft is fixedly arranged on the side wall of the mounting block above the T-shaped grooves, and a cover plate that cooperates with the H-shaped quick-installation block is offset and rotatably arranged on the first fixing shaft.

[0012] This utility model also proposes a track flaw detection device, including the detachable track flaw detection chassis structure described in any of the above: a tray, set at the tail end of the longitudinal frame, with a container for holding flaw detection fluid on top, and the container is positioned by a limiting component, with a liquid outlet pipe connected to the container and a nozzle connected to the end of the liquid outlet pipe; two sets of hinged frames, respectively hinged to both sides of the longitudinal frame, with rotatable cleaning wheels inside for wiping away the flaw detection fluid;

[0014] Preferably, the limiting component includes limiting seats symmetrically fixed to the top of the tray, the limiting seats having a longitudinally penetrating straight slot hole, the limiting seats having a plurality of limiting holes communicating with the straight slot hole, a limiting frame that cooperates with the top wall of the receiving bucket being provided between the two limiting seats, and a connecting shaft that slides in the straight slot hole and cooperates with the limiting hole being horizontally fixed at the bottom of the limiting frame.

[0015] The above technical solution has the following advantages or beneficial effects:

[0016] 1. In this utility model, the track flaw detection chassis is designed as a detachable structure. After disassembly, the transverse frame and the longitudinal frame set at both ends of the transverse frame are separated, which solves the problem of the existing track flaw detection chassis being large in size and heavy in weight. It saves space when stored and can be used by only one person, avoiding the problem of limited scope of use.

[0017] 2. In this utility model, mounting blocks connected to the longitudinal frame are slidably arranged at both ends of the transverse frame, and an adjustment component for driving the mounting blocks to slide and achieving self-locking is provided between the mounting blocks and the transverse frame.

The flaw detection fluid inside is sprayed onto the track through a nozzle, and the flaw detection fluid on the track is wiped off by a cleaning wheel. If there is a crack in the track, the flaw detection fluid will seep into it. The outline of the crack containing the flaw detection fluid will be more obvious in the dark environment, which will enable the industrial camera to accurately capture the crack image for subsequent analysis and processing.

[0034] like Figures 1-9 As shown, this utility model provides a technical solution:

[0035] A detachable track flaw detection chassis structure, including a transverse frame 1, combined with... Figure 1 and Figure 2As shown, a hinge seat 2 is fixedly installed at the top and middle position of the horizontal frame 1. A support rod 3 is hinged to the upper hinge seat 2, and a mounting bracket 4 is hinged to the top of the support rod 3. An industrial camera is connected to the mounting bracket 4. A first handle 5 is fixedly installed at the top of the horizontal frame 1 and on one side of the hinge seat 2. Laterally sliding mounting blocks 6 are respectively provided at both ends of the horizontal frame 1. Figure 3 As shown, both ends of the horizontal frame 1 are provided with first slots 7. The mounting block 6 is fixedly provided with a first insert block 8 that mates with the first slot 7 on one side. The outer walls of both sides of the horizontal frame 1 are provided with guide grooves 9 that communicate with the first slots 7. The outer walls of both sides of the first insert block 8 are fixedly provided with elastic guide blocks 10 that mate with the guide grooves 9. The elastic guide blocks 10 are configured to be pressable by means of springs.

[0036] Preferably, by setting two sliding mounting blocks 6, the width of the track flaw detection chassis can be adjusted, which can be applied to three situations: standard gauge, narrow gauge and wide gauge, and has a wide range of applications.

[0037] Specifically in this embodiment, combined with Figure 1 and Figure 3 As shown, an adjustment assembly 11 for driving the mounting block 6 to slide is provided between the horizontal frame 1 and the mounting block 6. Furthermore, combined with... Figure 7 As shown, the adjustment assembly 11 includes a first connecting seat 1101 fixed to the top of the transverse frame 1 and a second connecting seat 1102 fixed to the top of the mounting block 6. A forward threaded rod 1103 is fixedly arranged on the inner side of the first connecting seat 1101, and a reverse threaded rod 1104 is fixedly arranged on the inner side of the second connecting seat 1102. A bidirectional threaded sleeve 1105 that cooperates with the forward threaded rod 1103 and the reverse threaded rod 1104 is sleeved on the outer side of the bidirectional threaded sleeve 1105. A plum blossom handle 1106 is fixedly arranged on the outer side of the bidirectional threaded sleeve 1105. A locking nut 1107 is fitted on the outer side of the forward threaded rod 1103 and at one end of the bidirectional threaded sleeve 1105. A locking nut 1107 for limiting the bidirectional threaded sleeve 1105 is fitted on the outer side of the reverse threaded rod 1104 and at the other end of the bidirectional threaded sleeve 1105.

[0038] Specifically in this embodiment, combined with Figure 3 , Figure 4 and Figure 5 As shown, both mounting blocks 6 have detachable longitudinal frames 12 on their outer sides. Furthermore, a second groove is formed on one end of the longitudinal frame 12 near the mounting block 6. A second protrusion 13, which mates with the second groove, is fixedly provided on the side of the mounting block 6 away from the first insert block 8. A quick-release assembly 14 is provided between the mounting block 6 and the longitudinal frame 12 for quickly fixing the longitudinal frame 12 and the mounting block 6 together.

A handle 1403 is fixedly provided on the outer side and near the lower side of the H-shaped quick-release block 1402. A first fixing shaft 1404 is fixedly provided on the side wall of the mounting block 6 above the T-shaped grooves 1401. An offset and rotatable joint is provided on the first fixing shaft 1404 that is aligned with the H-shaped quick-release block 1402. The cover plate 1405 that mates with the quick-release block 1402 should be noted as follows: the first fixing shaft 1404 is set as a T-shaped structure to prevent the cover plate 1405 from detaching from the first fixing shaft 1404. A second fixing shaft 1406 is fixedly set on the side wall of the longitudinal frame 12 and on one side of the T-shaped groove 1401. A connecting rope 1407 is set between the second fixing shaft 1406 and the handle 1403. Preferably, the connecting rope 1407 is set to prevent the H-type quick-release block 1402 from being lost during transportation.

[0039] Preferably, the track flaw detection chassis is designed as a detachable structure. After disassembly, the transverse frame 1 and the longitudinal frames 12 set at both ends of the transverse frame 1 can be separated. This solves the problem of the large size and heavy weight of the existing track flaw detection chassis, making it easy to carry and complete the operation. It saves space when stored and can be used by only one person, avoiding the problem of limited scope of use. In addition, the track flaw detection chassis can be quickly assembled by the quick-assembly component 14, which is simple and convenient to operate and improves work efficiency.

[0040] Specifically in this embodiment, combined with Figure 2 As shown, the bottom of the longitudinal frame 12 is rotatably equipped with travel wheels 16 that cooperate with the top of the track near both ends, and the bottom of the longitudinal frame 12 is provided with multiple sets of guide wheels 17 that cooperate with the side wall of the track at intervals.

[0041] A track flaw detection device includes a longitudinal frame 12, combined with... Figure 1 and Figure 3 As shown, a tray 18 is fixedly installed on the top of the longitudinal frame 12 and near the rear side in the direction of travel. A container 19 for holding flaw detection fluid is placed on the tray 18. A limiting component 20 for fixing the container 19 is provided on the tray 18. Furthermore, combined with Figure 8 and Figure 9As shown, the limiting assembly 20 includes limiting seats 2001 symmetrically fixed to the top edge of the tray 18. A straight slot 2002 is longitudinally opened through the limiting seat 2001. A plurality of limiting holes 2003 connected to the straight slot 2002 are opened on the limiting seat 2001. A limiting frame 2004 that cooperates with the top wall of the receiving tank 19 is provided between the two limiting seats 2001. A connecting shaft 2005 that slides in the straight slot 2002 and cooperates with the limiting holes 2003 is horizontally fixed at the bottom of the limiting frame 2004. A liquid outlet pipe 21 that communicates with the receiving tank 19 and extends backward is fixedly provided on the outer wall of the receiving tank 19. A nozzle 22 is fixedly provided at the end of the liquid outlet pipe 21. Two hinged frames 23 are hinged to the end of the longitudinal frame 12. A cleaning wheel 24 that cooperates with the top of the track is rotatably arranged between the ends of the two hinged frames 23.

[0042] Preferably, a container 19 for holding the flaw detection fluid is placed on top of the tray 18. A discharge pipe 21 is provided at the rear of the container 19, and a nozzle 22 is provided at the end of the discharge pipe 21. A cleaning wheel 24 is rotatably installed at the end of the longitudinal frame 12 and behind the nozzle 22. The flaw detection fluid is sprayed onto the track through the nozzle 22, and the flaw detection fluid on the track is wiped away by the cleaning wheel 24. If there are cracks in the track, the flaw detection fluid will seep into them, and the flaw detection fluid in the cracks is difficult to completely remove by the cleaning wheel 26. The outline of the crack containing the flaw detection fluid will be more obvious in low light conditions, and the industrial camera can more accurately capture the crack image for subsequent analysis and processing.

[0043] The working principle of the track flaw detection equipment in this utility model is as follows:

[0044] In use, the transverse frame 1 and two longitudinal frames 12 are moved to one side of the track. First, one of the longitudinal frames 12 is connected to the transverse frame 1. When connecting, one end of the longitudinal frame 12 is aligned with one end of the transverse frame 1. At this time, the second protrusion 12 is inserted into the first groove, and the two T-shaped grooves overlap to form an H-shaped groove. Next, the angle of the cover plate 1405 is rotated. When the cover plate 1405 is rotated until the two T-shaped grooves 1401 are completely exposed, it stops. Then, the H-shaped quick-release block 1402 is inserted into the two overlapping H-shaped grooves. When the H-shaped quick-release block 1402 is inserted, the outer side of the H-shaped quick-release block 1402 is aligned with the outer wall of the mounting block 6. Finally, the angle of the cover plate 1405 is rotated so that the cover plate 1405 engages with the H-shaped quick-release block 1402 to prevent the H-shaped quick-release block 1402 from automatically falling out of the T-shaped groove 1401. After one longitudinal frame 12 is installed, the other longitudinal frame 12 is installed at the other end of the transverse frame 1 in the same way.

[0045] When the other longitudinal frame 12 is installed, if the travel wheel 16 on the other longitudinal frame 12 cannot contact the top of the track due to the different track spacing, first adjust the locking nuts 1107 on the forward threaded rod 1103 and the reverse threaded rod 1104 respectively, so that the two locking nuts 1107 are away from the bidirectional threaded sleeve 1105. Then, rotate the bidirectional threaded sleeve 1105 through the plum blossom handle 1106 to adjust the spacing between the mounting block 6 and the transverse frame 1, that is, the spacing between the two longitudinal frames 12. Stop when the travel wheel 16 on the other longitudinal frame 12 contacts the top of the track. Then adjust the position of the two locking nuts 1107 so that both locking nuts 1107 are in contact with both ends of the bidirectional threaded sleeve 1105, thus completing the limiting of the bidirectional threaded sleeve 1105.

[0046] Although the specific embodiments of the utility model have been described above in conjunction with the accompanying drawings, this is not intended to limit the scope of protection of the utility model. Based on the technical solution of the utility model, various modifications or variations that can be made by those skilled in the art without creative effort are still within the scope of protection of the utility model.
