Description

Technical Field

[0001] The invention belongs to the technical field of railway track maintenance, and specifically relates to a laser measuring instrument for frog wear of railway tracks. Background Art

[0002] A frog is a device that enables a wheel to cross from one rail to another. It includes a heart rail, left and right wing rails, and connecting parts. To ensure the stability and reliability of the frog structure, the design and maintenance of the frog are crucial for the safety of railway operations. When performing maintenance and repair operations on the frog, a measuring ruler is usually used to measure the wear degree of its rail body to facilitate the maintenance personnel's repair work.

[0003] When the existing measuring ruler measures the wear of the frog track, to improve the measurement accuracy, a clamping structure needs to be adopted at both ends of the measuring ruler. The clamping structures at both ends of the measuring ruler are respectively clamped on the left and right wing rails to provide support for the measuring ruler. However, since the left and right wing rails and the heart rail of the frog track are not in a parallel state, that is, the distances between the left and right wing rails are not the same, the two sets of clamping structures can only be clamped at a certain position of the left and right wing rails, and the measuring ruler can only measure the corresponding positions of the left and right wing rails and the heart rail, resulting in incomplete measured data and poor measurement effects. Summary of the Invention

[0015] The embodiments of the present invention will be described in detail below. The examples of the embodiments are shown in the drawings, in which the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the drawings are exemplary only for explaining the present invention and should not be construed as limiting the present invention.

[0016] Please refer to Figure 1 、 Figure 2 and Figure 4 Figure 4

[0017] When it is necessary to measure the frog wear, the two sets of movable clamping components 30 can be unfolded, and then the two sets of movable clamping components 30 are respectively placed outside the left and right wing rails. Subsequently, the two sets of movable clamping components 30 are released. Under the supporting action of the two sets of elastic supporting components 20, the two sets of movable clamping components 30 are respectively clamped on the outer walls of the left and right wing rails, so as to complete the supporting operation of the measuring component 50. After the supporting of the measuring component 50 is completed, the adjusting component 40 can be used to drive the measuring component 50 to move along the length direction of the guide rod 10, so that the measuring component 50 moves above the left wing rail, the heart rail and the right wing rail, so as to measure the wear conditions of the left wing rail, the heart rail and the right wing rail.

[0018] Please refer to Figure 1 and Figure 4 Figure 4

[0019] When it is necessary to measure the frog wear, the clamping plates 301 corresponding to the two sets of movable clamping components 30 can be pulled to make the two clamping plates 301 move away from each other. Then, the two clamping plates 301 are respectively placed outside the left and right wing rails. Subsequently, the two clamping plates 301 are released. Under the supporting action of the first elastic members 202 corresponding to the two sets of elastic supporting components 20, the two clamping plates 301 can be respectively clamped on the outer walls of the left and right wing rails.

[0020] Please refer to Figure 1 and Figure 3 In one embodiment, the measuring assembly 50 includes a sliding column 501, a mounting ring plate 502 and a laser measuring instrument 506. The sliding column 501 is slidably disposed outside the guide rod 10. The mounting ring plate 502 is fixedly disposed at the bottom of the sliding column 501. The laser measuring instrument 506 is fixedly mounted at the bottom of the mounting ring plate 502. The adjusting assembly 40 includes a second elastic member 401, an adjusting slide plate 402 and a screw rod 403. The adjusting slide plate 402 is slidably disposed outside the guide rod 10. One end of the second elastic member 401 is connected to the adjusting slide plate 402, and the other end is connected to the sliding column 501. One end of the screw rod 403 is rotatably engaged with the adjusting slide plate 402, and the other end penetrates through one set of the clamping plates 301 and is threadedly engaged with this set of the clamping plates 301.

[0021] After the two sets of clamping plates 301 are clamped on the outer walls of the left and right wing rails, when it is necessary to measure the wear of the left wing rail, the staff can rotate the screw rod 403. Through the threaded engagement between the screw rod 403 and the corresponding clamping plate 301, the adjusting slide plate 402 is driven to slide leftward along the guide rod 10. When the adjusting slide plate 402 slides leftward, the sliding column 501 is pushed to slide leftward along the guide rod 10 synchronously through the second elastic member 401. When the sliding column 501 slides leftward, the laser measuring instrument 506 is driven to move leftward through the mounting ring plate 502 at its bottom, so as to adjust the laser measuring instrument 506 above the left wing rail, and then measure the wear condition of the left wing rail. Similarly, when it is necessary to measure the switch rail or the right wing rail, the laser measuring instrument 506 can also be correspondingly adjusted above the switch rail or the right wing rail by rotating the screw rod 403 to measure the wear condition of the switch rail or the right wing rail.

[0022] Please refer to Figure 3 and Figure 4 In one embodiment, a column 303 is rotatably disposed at the bottom of the clamping plate 301. The surface of the column 303 is consistent with the concave shape on the outer wall of the wing rail. A sleeve 504 is rotatably sleeved on the outer wall of the mounting ring plate 502. An extension side plate 505 is fixedly disposed on the outer wall of the sleeve 504. A telescopic column cylinder 507 is fixedly disposed at the bottom of the extension side plate 505. A telescopic guide post 509 is movably inserted into the bottom of the telescopic column cylinder 507.

[0023] When it is necessary to measure the wear condition of the left wing rail, the screw 403 can be rotated. By the threaded engagement of the screw 403 with the corresponding clamping plate 301, the adjusting slide plate 402 is driven to slide leftward along the outside of the guide rail 10. Then, the second elastic member 401 is used to push the sliding column 501, so that the sliding column 501 slides leftward synchronously along the outside of the guide rod 10. When the sliding column 501 slides leftward, it drives the mounting ring plate 502, the laser measuring instrument 506, the extending side plate 505, the telescopic column barrel 507 and the telescopic guide post 509 to move leftward synchronously. When the telescopic guide post 509 acts on the inner wall of the left wing rail, the laser measuring instrument 506 is exactly located directly above the left wing rail. At this time, the wear of the left wing rail can be measured by using the laser measuring instrument 506. After the telescopic guide post 509 acts on the inner wall of the left wing rail, the screw 403 is rotated continuously, so as to drive the adjusting slide plate 402 to continue sliding leftward along the guide rod 10, thereby driving the second elastic member 401 to be in a compressed state, so that the telescopic guide post 509 is in close contact with the inner wall of the left wing rail. When it is necessary to measure the wear condition of the right wing rail, the telescopic guide post 509 can be pushed upward, so that the telescopic guide post 509 moves into the telescopic column barrel 507. Then, the sleeve 504 is rotated, so as to drive the extending side plate 505, the telescopic column barrel 507 and the telescopic guide post 509 to rotate 180° as a whole around the mounting ring plate 502. Subsequently, the screw 403 is rotated in the reverse direction. By the threaded engagement of the screw 403 with the corresponding clamping plate 301, the adjusting slide plate 402 is driven to slide rightward along the outside of the guide rod 10. Then, the second elastic member 401 is used to pull the sliding column 501, so that the sliding column 501, the mounting ring plate 502, the extending side plate 505, the laser measuring instrument 506, the telescopic column barrel 507 and the telescopic guide post 509 move rightward synchronously. When the laser measuring instrument 506 passes over the center rail, the telescopic guide post 509 is pulled downward, so that the telescopic guide post 509 extends out of the telescopic column barrel 507. Subsequently, the screw 403 is rotated continuously in the reverse direction until the telescopic guide post 509 acts on the inner wall of the right wing rail, and the laser measuring instrument 506 is exactly located directly above the right wing rail. The wear of the right wing rail is measured by using the laser measuring instrument 506. After the telescopic guide post 509 acts on the inner wall of the right wing rail, the screw 403 is rotated continuously in the reverse direction, so as to drive the adjusting slide plate 402 to continue sliding rightward along the guide rod 10, thereby driving the second elastic member 401 to be in a stretched state, so that the telescopic guide post 509 is in close contact with the inner wall of the right wing rail. Similarly, when it is necessary to measure the wear condition of the center rail, the screw 403 can also be rotated to drive the sliding column 501, the mounting ring plate 502, the extending side plate 505, the laser measuring instrument 506, the telescopic column barrel 507 and the telescopic guide post 509 to move until the telescopic guide post 509 acts on the side wall of the center rail and the laser measuring instrument 506 is located directly above the center rail, so as to realize the measurement of the wear of the center rail;After the measurement is completed at a certain position on the left and right wing rails and the switch point rail, the staff can push the two sets of clamping plates 301 along the length direction of the left and right wing rails. When the two sets of clamping plates 301 are pushed, the columns 303 at their bottoms roll within the concave surfaces on the outer walls of the left and right wing rails, thereby providing rolling support for the movement of the two sets of clamping plates 301 to improve the smoothness of the movement of the clamping plates 301. During the process of the two sets of clamping plates 301 moving along the length direction of the left and right wing rails, since the left and right wing rails and the switch point rail are not parallel, the two sets of clamping plates 301 will adaptively move away from or close to each other under the elastic support of the first elastic member 202 and always clamp on the outer walls of the left and right wing rails to provide stable support for the laser measuring instrument 506. When the two sets of clamping plates 301 move along the length direction of the left and right wing rails, they can drive the guide rod 10, the sliding column 501, the laser measuring instrument 506, the adjusting slide plate 402, the screw rod 403, the telescopic cylinder 507 and the telescopic guide post 509 to move synchronously. When the telescopic guide post 509 moves, it cooperates with the pushing and pulling action of the second elastic member 401 on the sliding column 501. The telescopic guide post 509 can slide along the side wall of a certain group of tracks, thereby positioning the laser measuring instrument 506 so that the laser measuring instrument 506 can move along the position directly above a certain group of tracks, so as to measure the wear at different positions of the current track.

[0024] Please refer to Figure 3 , in one embodiment, a third elastic member 508 for providing elastic support to the telescopic guide post 509 is arranged inside the telescopic cylinder 507.

[0025] After the telescopic guide post 509 is retracted into the telescopic cylinder 507 and passes over the position above the switch point rail, the telescopic guide post 509 can be released. Under the support of the third elastic member 508, the telescopic guide post 509 can quickly move downward and then extend out of the telescopic cylinder 507 to facilitate quickly positioning the moving position of the laser measuring instrument 506.

[0026] Please refer to Figure 3 , in one embodiment, a locking bolt 503 is arranged on the sleeve 504. After the sleeve 504 rotates 180° around the mounting ring plate 502 to adjust the directions of the telescopic cylinder 507 and the telescopic guide post 509, the staff can turn the locking bolt 503 so that the locking bolt 503 abuts against the outer wall of the mounting ring plate 502 to lock the sleeve 504, thereby locking the telescopic cylinder 507 and the telescopic guide post 509 to improve the stability of the telescopic cylinder 507 and the telescopic guide post 509.

[0027] Please refer to Figure 4 , in one embodiment, a positioning block 302 is fixedly arranged on the side wall of the clamping plate 301, and the shape of the bottom of the positioning block 302 is the same as the shape of the upper edge of the wing rail.

[0028] After the two sets of splints 301 are respectively clamped on the outer walls of the left and right wing rails, the cylinders 303 at the bottoms of the two sets of splints 301 are fitted into the concave surfaces on the outer walls of the left and right wing rails. At the same time, the positioning blocks 302 on the side walls of the two sets of splints 301 are attached to the outer sides of the upper edges of the left and right wing rails. Through the cooperation of the positioning blocks 302 and the cylinder barrels 303, the positioning of the splints 301 can be realized.

[0029] In one embodiment, the first elastic member 202, the second elastic member 401, and the third elastic member 508 can be springs or metal shrapnel, and there is no limitation here.

[0030] In one embodiment, the measurement principle of the laser measuring instrument 506 for the wear of the left and right wing rails and the frog rail is as follows: When the laser measuring instrument 506 measures a certain value above the wear of the left wing rail, the right wing rail, or the frog rail, subtract the distance value between the left wing rail, the right wing rail, or the frog rail in the non-worn state and the laser measuring instrument 506 from this value to obtain the actual wear value.

[0031] In the embodiment of the present invention, when it is necessary to measure the frog wear, the two sets of movable clamping components 30 can be unfolded, and then the two sets of movable clamping components 30 are respectively placed on the outer sides of the left and right wing rails. Subsequently, the two sets of movable clamping components 30 are released. Under the supporting action of the two sets of elastic supporting components 20, the two sets of movable clamping components 30 are respectively clamped on the outer walls of the left and right wing rails, thereby completing the supporting operation of the measuring component 50. After the measuring component 50 is supported, the adjusting component 40 can be used to drive the measuring component 50 to move along the length direction of the guide rod 10, so that the measuring component 50 moves above the left wing rail, the frog rail, and the right wing rail to measure the wear conditions of the left wing rail, the frog rail, and the right wing rail. Compared with the prior art, through the cooperation of the guide rod 10, the two sets of movable clamping components 30, the two sets of elastic supporting components 20, and the adjusting component 40, the measuring component 50 can be stably supported at different positions of the frog rail, and then the wear at different positions of the wing rail and the frog rail of the frog rail can be stably measured, having the advantages of comprehensive measurement data and good measurement effect.

[0032] The above has described the preferred embodiments of the present invention in detail, but the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those of ordinary skill in the art, various changes can be made without departing from the gist of the present invention.
