[0002] A frog is a device that allows the wheels to cross from one rail to another. It consists of 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 to the safety of railway operations. When performing maintenance and inspection on the frog, it is usually necessary to use a measuring ruler to measure the degree of wear on the rail body to facilitate maintenance personnel's inspection work.

[0003] When measuring the wear of the frog rail using an existing measuring ruler, in order to improve the measurement accuracy, it is necessary to adopt a clamping structure at both ends of the measuring ruler.

The elastic support assembly 20 is provided with two groups, and the two groups of elastic support assemblies 20 are respectively mounted at both ends of the guide rod 10, for respectively providing elastic support for the two groups of movable clamping assemblies 30, so that the two groups of movable clamping assemblies 30 are respectively clamped on the outer walls of the left and right wing rails, the measuring assembly 50 is arranged between the two groups of movable clamping assemblies 30 and slidably cooperates with the guide rod 10, and the adjusting assembly 40 is mounted on one of the groups of movable clamping assemblies 30, for driving the measuring assembly 50 to move along the length direction of the guide rod 10.

[0030] When it is necessary to measure the frog wear, the two sets of movable clamping assemblies 30 can be unfolded, and then the two sets of movable clamping assemblies 30 can be placed on the outside of the left and right wing rails respectively, and then the two sets of movable clamping assemblies 30 can be loosened. Under the support of the two sets of elastic support assemblies 20, the two sets of movable clamping assemblies 30 are respectively clamped on the outer walls of the left and right wing rails, thereby completing the supporting operation of the measuring assembly 50. After the measuring assembly 50 is supported, the adjusting assembly 40 can be used to drive the measuring assembly 50 to move along the length direction of the guide rod 10, and then the measuring assembly 50 is moved to above the left wing rail, the heart rail and the right wing rail to measure the wear of the left wing rail, the heart rail and the right wing rail.

[0031] See also Figure 1 as well as Figure 4 In one embodiment, the movable clamping assembly 30 includes a splint 301, which is slidably arranged on the outside of the guide rod 10. The elastic support assembly 20 includes a support end plate 201 and a first elastic member 202. The support end plate 201 is fixedly arranged at the end of the guide rod 10. One end of the first elastic member 202 is connected to the support end plate 201, and the other end is connected to the splint 301, for providing elastic support to the splint 301.

[0032] When it is necessary to measure the frog wear, the clamping plates 301 corresponding to the two sets of movable clamping assemblies 30 can be pulled to move the two sets of clamping plates 301 away from each other, and then the two sets of clamping plates 301 are respectively placed on the outer sides of the left and right wing rails, and then the two sets of clamping plates 301 are loosened. Under the support of the first elastic members 202 corresponding to the two sets of elastic support assemblies 20, the two sets of clamping plates 301 can be clamped on the outer walls of the left and right wing rails respectively.

[0033] See also Figure 1 as well as 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 arranged outside the guide rod 10, the mounting ring plate 502 is fixedly arranged at the bottom of the sliding column 501, and the laser measuring instrument 506 is fixedly installed at the bottom of the mounting ring plate 502. The adjusting assembly 40 includes a second elastic member 401, an adjusting slide 402 and a screw 403. The adjusting slide 402 is slidably arranged outside the guide rod 10, one end of the second elastic member 401 is connected to the adjusting slide 402, and the other end is connected to the sliding column 501. One end of the screw 403 is rotatably engaged with the adjusting slide 402, and the other end passes through one group of the splints 301 and is threadedly engaged with the group of the splints 301.

[0034] 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 403, and through the screw 403 and the thread cooperation of the corresponding clamping plate 301, the adjusting slide 402 is driven to slide to the left along the guide rod 10. When the adjusting slide 402 slides to the left, the second elastic member 401 pushes the sliding column 501 to slide synchronously to the left along the guide rod 10. When the sliding column 501 slides to the left, it drives the laser measuring instrument 506 to move to the left through the mounting ring plate 502 at its bottom, so as to adjust the laser measuring instrument 506 to above the left wing rail, and then measure the wear of the left wing rail; similarly, when it is necessary to measure the center rail or the right wing rail, the laser measuring instrument 506 can also be adjusted to above the center rail or the right wing rail by rotating the screw 403 to measure the wear of the center rail or the right wing rail.

[0035] See also Figure 3 as well as Figure 4 In one embodiment, a column 303 is rotatably provided at the bottom of the splint 301, and 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 provided on the outer wall of the mounting ring plate 502, and an extension side plate 505 is fixedly provided on the outer wall of the sleeve 504. A telescopic column 507 is fixedly provided at the bottom of the extension side plate 505, and a telescopic guide column 509 is movably inserted at the bottom of the telescopic column 507.

[0036] When it is necessary to measure the wear of the left wing rail, the screw 403 can be rotated, and the screw 403 can be used to cooperate with the thread of the corresponding clamping plate 301 to drive the adjusting slide 402 to slide to the left along the outside of the guide rail 10, and then the second elastic member 401 pushes the slide post 501 so that the slide post 501 slides to the left along the outside of the guide rod 10 synchronously. When the slide post 501 slides to the left, it drives the mounting ring plate 502, the laser measuring instrument 506, the extended side plate 505, the telescopic column 507 and the telescopic guide post 509 to move to the left synchronously. When the telescopic guide post 509 acts on the inner wall of the left wing rail, the laser measuring instrument 506 is just above the left wing rail. At this time, the laser measuring instrument 506 can be used to measure the wear of the left wing rail. The wear of the rail is measured. After the telescopic guide column 509 acts on the inner wall of the left wing rail, the screw 403 is continued to be rotated, thereby driving the adjusting slide 402 to continue to slide to the left along the guide rod 10, thereby driving the second elastic member 401 to be compressed, so that the telescopic guide column 509 is in close contact with the inner wall of the left wing rail. When the wear of the right wing rail needs to be measured, the telescopic guide column 509 can be pushed upward to move the telescopic guide column 509 toward the inside of the telescopic column tube 507, and then the sleeve 504 is rotated to drive the extended side plate 505, the telescopic column tube 507 and the telescopic guide column 509 to rotate 180 degrees around the mounting ring plate 502. Then the screw 403 is rotated in the opposite direction, and the screw 403 is used to contact the corresponding The threaded cooperation of the splint 301 drives the adjusting slide plate 402 to slide to the right along the outside of the guide rod 10, and then pulls the sliding post 501 through the second elastic member 401, so that the sliding post 501, the mounting ring plate 502, the extended side plate 505, the laser measuring instrument 506, the telescopic column 507 and the telescopic guide column 509 move to the right synchronously. When the laser measuring instrument 506 passes over the center rail, the telescopic guide column 509 is pulled downward so that the telescopic guide column 509 extends from the inside of the telescopic column 507. Then, the screw 403 is rotated in the opposite direction until the telescopic guide column 509 acts on the inner wall of the right wing rail. The laser measuring instrument 506 is just above the right wing rail. The wear of the telescopic guide column 509 is measured. After the telescopic guide column 509 acts on the inner wall of the right wing rail, the screw 403 is continued to be rotated in the opposite direction, thereby driving the adjusting slide plate 402 to continue to slide to the right along the guide rod 10, thereby driving the second elastic member 401 to be in a stretched state, so that the telescopic guide column 509 is in close contact with the inner wall of the right wing rail. Similarly, when it is necessary to measure the wear of the center rail, the screw 403 can also be rotated to drive the sliding column 501, the mounting ring plate 502, the extended side plate 505, the laser measuring instrument 506, the telescopic column tube 507 and the telescopic guide column 509 to move until the telescopic guide column 509 acts on the side wall of the center rail and the laser measuring instrument 506 is located directly above the center rail, thereby realizing the measurement of the center rail wear.After measuring a certain position on the left and right wing rails and the heart rail, the staff can push the two sets of splints 301 along the length direction of the left and right wing rails. When the two sets of splints 301 are pushed, the columns 303 at the bottom thereof roll along 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 splints 301 to improve the stability of the movement of the splints 301. In the process of the two sets of splints 301 moving along the length direction of the left and right wing rails, since the left and right wing rails and the heart rail are not arranged in parallel, the two sets of splints 301 will adaptively move away from or close to each other and always be clamped on the outer walls of the left and right wing rails under the elastic support of the corresponding first elastic members 202, so as to ensure the smooth movement of the two sets of splints 301. Providing stable support for the laser measuring instrument 506, the two sets of clamping plates 301 move along the length of the left and right wing rails, driving the guide rod 10, the slide post 501, the laser measuring instrument 506, the adjustment slide 402, the screw 403, the telescopic column 507, and the telescopic guide post 509 to move synchronously. The telescopic guide post 509, in conjunction with the push-pull action of the second elastic member 401 on the slide post 501, can slide against the sidewall of a particular set of rails, thereby providing positioning for the laser measuring instrument 506, allowing it to move directly above a particular set of rails, thereby measuring wear at different locations on the current rails.

[0037] See also Figure 3 In one embodiment, a third elastic member 508 is provided inside the telescopic column 507 for providing elastic support to the telescopic guide column 509 .

[0038] After the telescopic guide column 509 is retracted into the telescopic column tube 507 and passes over the position above the center rail, the telescopic guide column 509 can be loosened. Under the support of the third elastic member 508, the telescopic guide column 509 can move downward quickly and then extend from the telescopic column tube 507 to quickly locate the moving position of the laser measuring instrument 506.

[0039] See also Figure 3 In one embodiment, a locking bolt 503 is provided on the sleeve 504. After the sleeve 504 rotates 180° around the mounting ring plate 502 and adjusts the directions of the telescopic column 507 and the telescopic guide column 509, the staff can twist the locking bolt 503 so that the locking bolt 503 is supported against the outer wall of the mounting ring plate 502, thereby locking the sleeve 504, and then locking the telescopic column 507 and the telescopic guide column 509, so as to improve the stability of the telescopic column 507 and the telescopic guide column 509.

[0040] See also Figure 4 In one embodiment, a positioning block 302 is fixedly provided on the side wall of the clamping plate 301, and the bottom shape of the positioning block 302 is consistent with the shape of the upper edge of the wing rail.

[0041] After the two sets of splints 301 are respectively clamped on the outer walls of the left and right wing rails, the columns 303 at the bottom of the two sets of splints 301 are embedded in 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. The positioning processing of the splint 301 can be achieved through the cooperation between the positioning blocks 302 and the column tubes 303.

[0042] In one embodiment, the first elastic member 202 , the second elastic member 401 and the third elastic member 508 may be springs or metal springs, which are not limited herein.

[0043] In one embodiment, the laser measuring instrument 506 measures the wear of the left and right wing rails and the heart rail according to the following principle: when the laser measuring instrument 506 measures a certain value above the wear of the left wing rail, the right wing rail, or the heart rail, the distance value between the left wing rail, the right wing rail, or the heart rail and the laser measuring instrument 506 in the unworn state is subtracted from the value to obtain the actual wear value.

[0044] In the embodiment of the present invention, when it is necessary to measure the wear of the frog, the two sets of movable clamping assemblies 30 can be unfolded, and then the two sets of movable clamping assemblies 30 are respectively placed on the outer sides of the left and right wing rails, and then the two sets of movable clamping assemblies 30 are loosened. Under the support of the two sets of elastic support assemblies 20, the two sets of movable clamping assemblies 30 are respectively clamped on the outer walls of the left and right wing rails, thereby completing the supporting operation of the measuring assembly 50. After the measuring assembly 50 is supported, the adjusting assembly 40 can be used to drive the measuring assembly 50 to move along the length direction of the guide rod 10, and then the measuring assembly 50 is moved to above the left wing rail, the heart rail and the right wing rail to measure the wear of the left wing rail, the heart 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 assemblies 30, the two sets of elastic support assemblies 20 and the adjusting assembly 40, the measuring assembly 50 can be stably supported at different positions of the frog rail, thereby stably measuring the wear at different positions of the wing rails and the heart rail of the frog rail, which has the advantages of comprehensive measurement data and good measurement effect.

[0045] The preferred embodiments of the present invention are described in detail above, but the present invention is not limited to the above embodiments. Various changes can be made within the knowledge of ordinary technicians in this field without departing from the purpose of the present invention.
