Description

Technical Field

[0001] The present invention relates to the technical field of track detection, and in particular to a swing device and a track detector. Background Art

[0002] In order to ensure the safe operation of trains and subways, the railway department has very strict requirements for track inspection, and must ensure the safety of the track and the accuracy requirements during measurement. When using a power trolley combined with a track detector to perform rapid track inspection on the track, the connection device between the power trolley and the track detector is usually required to be flexible and movable to avoid affecting the measurement posture of the track detector and interfering with the measurement accuracy of the track detector.

[0003] When the track detector performs rapid track inspection, the power drive wheel is connected to the auxiliary beam of the track detector through a mechanical structure and transmits power to the track detector, so that its running wheels passively roll on the upper surface of the rail and move with the whole machine, and the track detector requires the auxiliary beam to always maintain a vertical positive pressure direction with the frame. However, in reality, the upper surfaces of the two rails are not absolutely straight and parallel. The direction limitation of the auxiliary beam will affect the running wheels of the measuring beam of the track detector and cannot fall completely on the upper surface of the rail. Summary of the invention

[0008] Furthermore, two first sliding beams are provided in the auxiliary beam, and a sliding bearing is provided at the bottom of the first connecting member. The sliding bearing slides on the first sliding beams, so that the two first sliding beams move relative to each other, thereby making the auxiliary beam adaptable to tracks of different sizes.

[0009] Furthermore, the connection structure includes a second connection member, which is disposed on one side of the device body and fixedly connected to the device body.

[0010] The present invention also proposes a track inspection instrument, including an auxiliary beam and the above-mentioned swinging device, the track inspection instrument also includes a measuring beam and a rotating assembly connecting the measuring beam and the auxiliary beam, the swinging device is connected to the auxiliary beam through the first connecting member, and the swinging device is connected to the rotating assembly through the second connecting member.

[0011] Furthermore, a third connecting member is provided on the side of the measuring beam facing the auxiliary beam, and matching members corresponding to the second connecting member and the third connecting member are respectively provided on the rotating assembly. The track inspection instrument also includes a positioning locking structure, and the matching member is connected to the second connecting member and the third connecting member through the positioning locking structure.

[0012] Furthermore, the second connecting member, the third connecting member and the mating member are all provided with positioning grooves, and the second connecting member and the third connecting member are provided with fixing grooves perpendicular to the positioning grooves.

[0032] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art of the present invention. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The term "and / or" used herein includes any and all combinations of one or more related listed items.

[0033] Embodiment 1

[0034] See also Figures 1 to 5 , shown is a swing device 200 in an embodiment of the present invention, which is applied to a track inspection instrument. The track inspection instrument includes an auxiliary beam 100, and the swing device 200 includes a device body 210 and a swing structure 230 and a connecting structure 220 respectively arranged at both ends of the device body 210. The swing structure 230 is connected to the device body 210, and the connecting structure 220 is respectively connected to the swing structure 230 and the auxiliary beam 100, wherein the swing structure 230 includes a swing member 231 movably connected to the connecting structure 220 and a swing limit member 232 respectively arranged at the upper and lower ends of the swing member 231, and the swing limit member 232 rotates relative to the central axis 2313 of the swing member 231 so that the auxiliary beam 100 swings within a preset angle range.

[0035] Specifically, a protrusion 2311 is provided in the middle of the swinging member 231 and protrudes upward, and a limiting portion 2312 is provided on the central axis 2313 of the protrusion 2311. The swing limiting member 232 includes swing limiting rollers which are respectively arranged at both ends of the limiting portion 2312. The swing limiting rollers are arranged on the protrusion 2311 and slide on the protrusion 2311.

[0036] It can be understood that when the auxiliary beam 100 runs on the track 600 with an inclined angle, the auxiliary beam 100 will be affected by the inclination of the track 600 and move in the direction away from the track 600. At this time, the auxiliary beam 100 pushes the swing member 231 to move synchronously in the direction away from the track 600 through the connecting structure 220. Since the swing limit member 232 is not in direct contact with the auxiliary beam 100, the swing limit roller of the swing limit member 232 rolls on the raised portion 2311 of the swing member 231 to realize the swing of the auxiliary beam 100 within a preset angle range. In this embodiment, the preset angle is greater than the slope parameter of the standard track 600 line and the angle caused by rail surface defects.

[0037] Further, the connection structure 220 includes a first connection member 221, and limiting holes 2211 are provided on both sides of the first connection member 221. A transverse limiting member 233 corresponding to the limiting holes 2211 is provided on the swing member 231, and the transverse limiting member 233 is inserted into the limiting holes 2211 to achieve the connection between the swing member 231 and the first connection member 221. During installation, the swing member 231 is first aligned with the first connection member 221, and the transverse limiting member 233 is inserted into the limiting holes 2211, and the first connection member 221 can be connected to the swing member 231 through the transverse limiting member 233.

[0038] In this embodiment, two first sliding beams 110 are provided in the auxiliary beam 100, and a sliding bearing 2212 is provided at the bottom of the first connecting member 221. The sliding bearing 2212 is arranged on the first sliding beam 110 and slides on the first sliding beam 110, so that the two first sliding beams 110 move relative to each other, thereby making the size of the auxiliary beam 100 adjustable to adapt to rails 600 of different sizes.

[0039] Furthermore, the connection structure 220 also includes a second connection member 222, which is arranged on one side of the device body 210 and fixedly connected to the device body 210. In this embodiment, the track inspection instrument also includes a measuring beam 300, and the device body 210 is connected to the measuring beam 300 through the second connection member 222.

[0040] In summary, the swing device in the above embodiment of the present invention provides a small-angle swing function for the auxiliary beam 100 by setting a swing member and a swing limit member, and allowing the swing limit member to rotate relative to the central axis of the swing member, so that the auxiliary beam can swing around the central axis within a certain range, ensuring that the track inspection instrument always falls on the upper surface of the track, thereby ensuring that the track inspection instrument can maintain the measuring posture in the fast measurement state and keep the measuring wheel spacing between the beams unchanged.

[0041] Embodiment 2

[0042] See also Figures 6 to 10 , shown is a track inspection instrument in a second embodiment of the present invention, including an auxiliary beam 100 and the swing device 200 in the first embodiment, the track inspection instrument also includes a measuring beam 300 and a rotating assembly 400 connecting the measuring beam 300 and the auxiliary beam 100, the swing device 200 is connected to the auxiliary beam 100 through the first connecting member 221, and the swing device 200 is connected to the rotating assembly 400 through the second connecting member 222.

[0043] It can be understood that the measuring beam 300 and the auxiliary beam 100 are respectively connected to the rotating assembly 400, and the swing device 200 is set on the auxiliary beam 100, so that the auxiliary beam 100 has a small-angle swing function, thereby enabling the rotating assembly 400 to swing at a small angle on the inclined track surface.

[0044] In this embodiment, in order to prevent the deflection torque caused by the offset of the swing device 200 from affecting the track inspection instrument's posture, the swing device 200 should be installed on the center plane of the track inspection instrument (ie, the center plane between the two rails).

[0045] Furthermore, a third connecting member 310 is provided on the side of the measuring beam 300 facing the auxiliary beam 100, and matching members 410 corresponding to the second connecting member 222 and the third connecting member 310 are respectively provided on the rotating assembly 400. The track inspection instrument also includes a positioning locking structure 500, and the matching member 410 is connected to the second connecting member 222 and the third connecting member 310 through the positioning locking structure 500.

[0046] It can be understood that the positioning and locking structure 500 can connect and fasten the auxiliary beam 100 and the measuring beam 300, thereby ensuring that when the track inspection instrument travels on the track surface of the track 600, the auxiliary beam 100 can swing with the inclination of the track 600, thereby ensuring that the measurement accuracy of the track inspection instrument will not be affected by the inclination of the track 600.

[0047] Specifically, the second connecting member 222, the third connecting member 310 and the matching member 410 are all provided with a positioning groove 411, and the second connecting member 222 and the third connecting member 310 are provided with a fixing groove 311 perpendicular to the positioning groove 411. The positioning locking structure 500 includes a handwheel 510, a positioning member 520 and a baffle 530. When the positioning member 520 is arranged in the fixing groove 311, the baffle 530 is covered on the fixing groove 311.

[0048] It can be understood that during installation, the mating piece 410 is first aligned with the positioning grooves 411 on the second connecting piece 222 and the third connecting piece 310, and then the positioning piece 520 is placed in the fixed groove 311, and it is ensured that the positioning piece 520 can be placed in the positioning groove 411, and the two ends of the positioning piece 520 are limited in the positioning groove 411 by fixing the baffle 530, and the mating piece 410 is fastened to the second connecting piece 222 and the third connecting piece 310 by rotating the hand wheel 510.

[0049] In this embodiment, two second sliding beams 320 are provided in the measuring beam 300, and a sliding member 330 is connected between the second sliding beam 320 and the measuring beam 300. The sliding member 330 is slidably arranged on the second sliding beam 320, so that the measuring beam 300 is adapted to tracks 600 of different sizes. When the track inspection instrument needs to adapt to tracks 600 of different sizes, the second sliding beam 320 on the measuring beam 300 is adjusted to make the second sliding beam 320 move relatively, and at the same time, the first sliding beam 110 on the auxiliary beam 100 is adjusted, so that the measuring beam 300 and the auxiliary beam 100 are adjusted to the corresponding track 600 size, so that the track inspection instrument is adapted to the track 600.

[0050] Furthermore, a first running wheel set 340 is provided on a side relatively far from the two first sliding beams 110, and a second running wheel set 340 is provided on a side relatively far from the two second sliding beams 320. The first running wheel set 340 and the second running wheel set push the track inspection instrument to walk on the track surface of the track 600. In this embodiment, the running wheel set 340 includes a running wheel 341, and the central axis of the running wheel 341 is colinear with the central axis 2313 of the swinging member 231. When the track inspection instrument walks on the track surface of the track 600, the running wheel 341 rolls and cooperates on the track surface; when an inclination angle appears on the track surface, the auxiliary beam 100 swings at a small angle under the action of the swinging device 200, and at the same time, the slewing assembly 400 rotates relative to the central axis of the running wheel 341 (i.e., the central axis 2313 of the swinging member 231), so that the slewing assembly 400 can swing at a small angle on the inclined track surface.

[0051] In summary, the track inspection instrument in the above-mentioned embodiment of the present invention has a swing device which provides a small-angle swing function of the auxiliary beam by setting a swing member and a swing limit member, and allowing the swing limit member to rotate relative to the central axis of the swing member, so as to enable the auxiliary beam to swing within a certain range around the central axis, thereby ensuring that the track inspection instrument always falls on the upper surface of the track when it moves, thereby ensuring that the track inspection instrument can maintain the measuring posture in the fast measurement state and keep the measuring wheel spacing between the beams unchanged.
