Detailed Implementation

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] The purpose of this invention is to provide a track inspection device that solves the problem of difficulty in passing turnouts and the need for manual intervention in the existing hand-push track inspection device. It significantly improves the stability and continuity of the track inspection device in the turnout area, and indirectly improves the detection accuracy of the track inspection device in the turnout area.

[0029] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0030] like Figures 1 to 6As shown, this utility model provides a track detector traveling device, including a frame 1, a first mounting frame 2 and a second mounting frame 3 distributed on both sides of the frame 1 perpendicular to its traveling direction and moving synchronously; two first fixed wheels 4, both traveling along the same rail 12, are rotatably mounted on the first mounting frame 2, and the two first fixed wheels 4 are spaced apart along the traveling direction. Preferably, two fixed frames are bolted to the first mounting frame 2, and the two fixed frames are spaced apart along the traveling direction, with the two first fixed wheels 4 rotatably mounted on the two fixed frames respectively; a second fixed wheel 13 is rotatably mounted on the second mounting frame 3. Preferably, a fixed frame is bolted to the second mounting frame 3, and the second fixed wheel 13 is rotatably mounted on the fixed frame on the second mounting frame 3. The second mounting frame 3 is provided with first connecting members 7 spaced apart from the second fixed wheel 13 along the traveling direction. A floating wheel assembly is movably provided on the first connecting member 7 in the vertical direction, and the first connecting member 7 has at least one... The first elastic component provides vertical tension to the floating wheel assembly, and can provide a certain buffering effect when the operating state changes to ensure the normal operation of the entire device. The floating wheel assembly is provided with a floating wheel 10. In this invention, the floating wheel assembly is movably installed on the first connecting member 7 in the vertical direction, and the first elastic component provides tension to the floating wheel assembly, so that the floating wheel 10 can float up and down in the vertical direction. The second fixed wheel 13 and the floating wheel 10 travel along another rail 12. Preferably, in the initial state, the first elastic component is in a semi-compressed state, and the initial height of the floating wheel 10 is lower than that of the second fixed wheel 13, so that when the entire track detector traveling device is set on the track, the first elastic component can maintain a certain tension under the reaction force of the rail 12, ensuring that the floating wheel 10 can make normal contact with the rail 12. The first fixed wheel 4, the second fixed wheel 13 and the floating wheel 10 do not enter the gaps in the rail 12 at the same time. The track inspection device disclosed in this utility model, when passing through a discontinuous area of ​​a turnout, for example, when the first fixed wheel 4 located at the front gets stuck in the gap of the rail 12, the first elastic element tensions the floating wheel assembly and the floating wheel 10 on the first connecting member 7 to maintain normal contact between the floating wheel 10 and the rail 12. This maintains normal contact between the other three wheels—the first fixed wheel 4, the second fixed wheel 13, and the floating wheel 10—and the rail 12. After the first fixed wheel 4 at the front passes through the gap of the rail 12, the floating wheel 10 is adjusted back to its normal state by the first elastic element. Subsequently, when the first fixed wheel 4, the second fixed wheel 13, and the floating wheel 10 located at the rear pass through the discontinuous area of ​​the turnout and get stuck in the gap of the rail 12, they are adjusted in the same way. Ultimately, the device can pass through the discontinuous area of ​​the turnout without manual assistance.

[0031] In one specific embodiment, the floating wheel assembly includes a floating wheel frame 9 movably mounted vertically on a first connecting member 7. It should be noted that, to ensure the floating wheel 10 and the second fixed wheel 13 can travel along the same rail 12, the first connecting member 7 is mounted at one end of the second mounting frame 3 along its traveling direction, and the floating wheel assembly is movably mounted vertically on the surface of the first connecting member 7 opposite to the second mounting frame 3. A first elastic component connects the first connecting member 7 and the floating wheel frame 9, and the floating wheel 10 is rotatably mounted on the floating wheel frame 9, so that the floating wheel 10 is installed through the floating wheel frame 9, thereby ensuring effective cooperation between the floating wheel 10 and the first connecting member 7. Preferably, the floating wheel 10 is connected to the floating wheel frame 9 via an axle.

[0032] In one specific embodiment, the first connecting member 7 has at least one vertically extending groove, and two first elastic components extending in the same direction are provided in the vertical groove. It should be noted that the vertical groove and the first elastic components are both mounted on the surface of the first connecting member 7 away from the second mounting bracket 3. Preferably, the first elastic components are spring structures. The floating wheel frame 9 has sliders matching the number of vertical grooves. The sliders are movably mounted in the vertical grooves and abut against the two first elastic components, so that the two first elastic components provide synchronous tension to the sliders within the same vertical groove. In this embodiment, preferably, the first connecting member 7 has multiple vertical grooves, each arranged at intervals along a horizontal direction and perpendicular to the direction of travel. Each vertical groove has a slider slidably mounted within it, and each slider is connected to the floating wheel frame 9. First elastic components are provided on both sides of each slider to comprehensively ensure that the first connecting member 7 applies a vertically extending tension to the floating wheel frame 9.

[0033] In one specific embodiment, a second connecting member 8 is fixedly connected to the side of the floating wheel frame 9 near the first connecting member 7, and is spaced apart from the floating wheel 10. The second connecting member 8 is movably mounted on the first connecting member 7 in the vertical direction. By setting the second connecting member 8 between the floating wheel frame 9 and the first connecting member 7, a gap is formed between the floating wheel frame 9 and the first connecting member 7 through the second connecting member 8, thereby ensuring that there is a gap between the floating wheel 10 and the first connecting member 7 for it to rotate, and avoiding positional interference between the floating wheel 10 and the first connecting member 7 during rotation.

[0034] In one specific embodiment, the floating wheel assembly is provided with a row wheel assembly, on which a row wheel 5 is rotatably connected. Preferably, the row wheel assembly is mounted on the floating wheel frame 9, and specifically, the row wheel assembly is provided with a row wheel frame 6. For example, the row wheel frame 6 is bolted to the floating wheel frame 9, and the row wheel 5 is rotatably mounted on the row wheel frame 6, preferably connected by an axle and bolts. A tensioning mechanism 11 is provided between the frame 1 and the second mounting frame 3, allowing the row wheel 5 to rotatably abut against the side wall of the rail 12. The tensioning mechanism 11 tensions the row wheel assembly and the row wheel 5, so that the row wheel 5 and the floating wheel 10 move together to achieve contact with the rail surfaces of different rails 12. Preferably, the row wheel frame 6 is located on one side of the floating wheel frame 9 perpendicular to the direction of travel, so that after the row wheel 5 is rotatably mounted on the row wheel frame 6, it can be located on one side of the floating wheel frame 9 and the rail 12, thereby ensuring that the row wheel 5 abuts against the side wall of the rail 12 under the tensioning action of the tensioning mechanism 11.

[0035] In one specific embodiment, the tensioning mechanism 11 includes a support assembly 17 mounted on the second mounting bracket 3 and located on the side of the second mounting bracket 3 near the frame 1. A movable assembly 19 is movably provided on the support assembly 17 along a horizontal direction and perpendicular to the direction of travel. The movable assembly 19 is mounted on the frame 1. The support assembly 17 has a frame structure and has a groove structure 18 extending horizontally and perpendicular to the direction of travel. Preferably, the support assembly 17 is connected to the second mounting bracket 3 by bolts. The movable assembly 19 has a slider structure and is slidably fitted into the groove structure 18. Preferably, the movable assembly 19 is connected to the frame 1 by bolts. At least one second elastic assembly 20 is connected between the support assembly 17 and the movable assembly 19. Preferably, the second elastic assembly 20 is a spring structure. The second elastic assembly 20 is used to provide a tension force horizontally and perpendicular to the direction of travel to the support assembly 17, the second mounting bracket 3, and the wheel 5. Preferably, there are multiple second elastic assemblies 20, which are spaced apart along the direction of travel to enhance the tension force on the wheel 5.

[0036] In this embodiment, preferably, the wheel 5 abuts against the side wall of one rail 12 near the other rail 12. The wheel assembly is then installed on the side of the floating wheel assembly near the other rail 12. In this case, the second elastic component 20 needs to be compressed beforehand. When the floating wheel assembly is set on the rail 12, the second elastic component 20 can apply a rebound force to the wheel 5 through the support component 17 and the second mounting bracket 3, thereby ensuring that the wheel 5 abuts against the side wall of the rail 12. Alternatively, preferably, the wheel 5 abuts against the side wall of one rail 12 away from the other rail 12. The wheel assembly is then installed on the side of the floating wheel assembly away from the other rail 12. In this case, the second elastic component 20 needs to be stretched beforehand. When the floating wheel assembly is set on the rail 12, the second elastic component 20 can apply a tensile force to the wheel 5 through the support component 17 and the second mounting bracket 3, thereby ensuring that the wheel 5 abuts against the side wall of the rail 12.

[0037] Preferably, multiple wheel frames 6 are installed on both the first mounting frame 2 and the second mounting frame 3. These wheel frames 6 are evenly distributed along the direction of travel, and each wheel frame 6 is rotatably connected to a wheel 5 for rotating and pressing against the side wall of the rail 12. It should be noted that the wheel frames 6 and wheels 5 on the first mounting frame 2, the second mounting frame 3, and the floating wheel frame 9 are all installed between the two rails 12 or on the outer side of the two rails 12. This comprehensively ensures the stability of the entire device during travel. Furthermore, each wheel frame 6 can be adjusted vertically. For example, the first mounting frame 2, the second mounting frame 3, and the floating wheel frame 9 have multiple positioning holes in the vertical direction, and the wheel frames 6 have mounting holes that communicate with each positioning hole. A bolt structure is detachably connected between the positioning holes and the mounting holes. The wheel frames 6 can be adjusted by connecting the mounting holes on the wheel frames 6 to the corresponding positioning holes and then inserting the bolt structure.

[0038] In one specific embodiment, the tensioning mechanism 11 further includes a tension adjustment mechanism, which includes two first tensioning rods 14 and two second tensioning rods 15. The two ends of the first tensioning rods 14 are a force-applying end and a first hinge end, respectively. The two ends of the second tensioning rods 15 are a second hinge end and a third hinge end, respectively. The third hinge ends of the two second tensioning rods 15 are respectively hinged to both sides of the support assembly 17 along its traveling direction. The second hinge ends of the two second tensioning rods 15 are respectively hinged to the first hinge ends of the corresponding first tensioning rods 14. The force-applying ends of both first tensioning rods 14 extend above the frame 1, and the two... A pull rod 16 is connected between the force-applying ends to facilitate force application. The middle portions of the two first tensioning rods 14 are respectively hinged to both sides of the frame 1. In specific operation, by applying force to the pull rod 16, the first tensioning rod 14 moves its first hinged end with its middle portion as the fulcrum. Since the first hinged end is hinged to the second hinged end, it in turn moves the second hinged end, the entire second tensioning rod 15, and the support assembly 17. And since the moving assembly 19 is mounted on the frame 1, the relative movement between the support assembly 17 and the moving assembly 19 is completed, thereby applying force to the second elastic assembly 20. This allows the position of the second mounting bracket 3 to be changed by operating the tension adjustment mechanism before travel, so that the wheel 5 can fully abut against the side wall of the rail 12.

[0039] In one specific embodiment, the frame 1 is further provided with a tensioning and locking mechanism to prevent the support assembly 17 from moving horizontally and perpendicular to the direction of travel. Specifically, the tensioning and locking mechanism includes a steel wire 25, a first locking member 21 and a second locking member 22 both disposed in the sliding groove structure 18 of the support assembly 17, and the first locking member 21 and the second locking member 22 are spaced apart along the entire direction of travel of the device. The first locking member 21 includes a first main frame, a first locking plate connected to the bottom end of the first main frame, and a locking screw 24 connected to the top end of the first main frame. Preferably, the first locking plate is bolted to the first main frame. The second locking member 22 is connected to the second main frame, a second locking plate connected to the bottom of the second main frame, and a guide frame 23 connected to the top of the second main frame. Preferably, the second locking plate is connected to the second main frame by bolts. The first locking plate and the second locking plate abut against the inner walls of the two sides of the slide structure 18 along the direction of travel of the entire device. The middle part of the first main frame and the middle part of the second main frame are respectively hinged to the frame 1. One end of the steel wire 25 is locked at the guide frame 23 and fixedly connected to the first main frame by locking screws 24. The other end is installed on the brake 27, and the brake 27 is installed on the frame 1. Preferably, the frame 1 is provided with a vertically extending push frame 26. The push frame 26 is provided with handles 28 on both sides for the operator to push. The brake 27 is installed on one side of the handle 28 through a brake 27 connector.

[0040] When a discontinuous area appears on the rail 12 below the floating wheel assembly, the operator operates the tensioning and locking mechanism. The brake 27 causes the steel wire 25 to retract, which in turn causes the first main frame and the second main frame to rotate around the part that is hinged to the frame 1 in the middle. This causes the first locking plate and the second locking plate to abut against the inner walls of the two sides of the slide structure 18, generating corresponding frictional force to prevent the support assembly 17 from moving with the second mounting bracket 3 in a direction perpendicular to the direction of travel. As a result, the wheel 5 stops moving, preventing it from getting stuck in the gap under the tension force when passing through the discontinuous gap of the rail 12. Therefore, the entire device can continue to move forward.

[0041] Any adaptive changes made according to actual needs are within the protection scope of this utility model.
