[0021] 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.

[0022] Please see Figure 1 and Figure 2 It is understood that this utility model provides a technical solution: an intelligent measuring instrument for contact wire geometric parameters, including: a support frame 1, pulleys 2, a measuring host 3, a connecting rod 4 and a push rod 5. Pulleys 2 are installed at the bottom of both ends of the support frame 1. The measuring host 3 is installed on the surface of the support frame 1. The connecting rod 4 is installed at the front of the support frame 1. The push rod 5 is set at the top of the connecting rod 4. The bottom of the push rod 5 is connected to a telescopic rod 6. A slot 7 is opened inside the telescopic rod 6.

[0023] The intelligent measuring instrument for contact wire geometric parameters has an integrated structure of telescopic rod 6 and push rod 5.

[0024] exist Figures 1-4 In the middle: a fixing block 8 is welded to the outside of the connecting rod 4, a sliding rod 9 is slidably connected inside the fixing block 8, a moving plate 10 is connected to the end of the sliding rod 9, a compression spring 11 is connected between the moving plate 10 and the fixing block 8, a plug-in block 12 is connected to the side of the moving plate 10 near the telescopic rod 6, a through hole 13 is opened on the top of the fixing block 8, and a stop block 14 is movably connected to the top of the fixing block 8 near the through hole 13 through a rotating shaft.

[0025] The intelligent measuring instrument for contact wire geometric parameters has a stop 14 to prevent the slide bar 9 from becoming loose.

[0026] exist Figures 1-4 In the middle: the telescopic rod 6 and the connecting rod 4 form a sliding structure, the plug block 12 and the connecting rod 4 form a plug-in structure, and the slots 7 are evenly distributed on the telescopic rod 6.

[0027] The intelligent measuring instrument for contact network geometric parameters has rectangular shapes for both the plug-in block 12 and the slot 7.

[0028] In practical implementation, the contact wire geometric parameter measuring instrument can measure various data of the contact wire, making it convenient for personnel to confirm the safety of the railway track based on the data. The height of the traditional push rod 5 is relatively fixed, making it difficult to adjust the push rod 5 according to the user's habits and height, which makes the contact wire geometric parameter measuring instrument less smooth to use and affects the measurement efficiency. The top of the stop block 14 can be flipped through the rotating shaft, so that the bottom of the stop block 14 can be moved away from the outside of the moving plate 10 and rotated out through the through hole 13, so that the stop block 14 can fall on the top of the fixed block 8. At this time, the sliding rod 9 can be pulled away from the telescopic rod 6. When the sliding rod 9 moves, it can drive the moving plate 10 to move. When the moving plate 10 moves, it can drive the plug block. 12 moves, and at the same time, the moving plate 10 can compress the compression spring 11. When the plug block 12 moves, it can slide out from inside a set of slots 7, thereby pulling the push rod 5. When the push rod 5 moves, it can drive the telescopic rod 6 to move. When the designated set of slots 7 on the telescopic rod 6 moves to the outside of the end of the plug block 12, the slide rod 9 can be released, so that the compression spring 11 can be reset. The end of the plug block 12 can be inserted into the inside of the designated set of slots 7, thereby fixing the telescopic rod 6. At this time, the height of the push rod 5 can be adjusted to the designated height according to its own needs. Then the stop block 14 is flipped, so that one end of the stop block 14 can be rotated to the side of the moving plate 10, which can effectively prevent the slide rod 9 from loosening.

[0029] See Figures 1-4 It can be seen that by adjusting the height of the push rod 5, the staff can use the push rod 5 according to their own usage habits and needs, which makes the contact wire geometric parameter measuring instrument smoother and more convenient to use, and can improve its measurement efficiency.

[0030] exist Figure 1 and Figure 5 In the middle: a horizontal plate 15 is connected to the top of the support frame 1 near the pulley 2. A threaded post 16 and a limiting plate 19 are connected to the top of the horizontal plate 15 respectively. A first threaded ring 17 and a second threaded ring 18 are threadedly connected to the outer side of the threaded post 16 respectively.

[0031] The intelligent measuring instrument for contact wire geometric parameters includes a limit plate 19 that prevents the L-shaped connecting plate 20 and the push block 21 from shifting.

[0032] exist Figure 1 , Figure 5 and Figure 6 In the middle: an L-shaped connecting plate 20 is sleeved on the outside of the threaded column 16, a push block 21 is connected to the outside of the end of the L-shaped connecting plate 20, and a wear-resistant cloth sheet 22 is connected to the bottom of the push block 21.

[0033] The intelligent measuring instrument for overhead contact line geometric parameters, pusher 21 and wear-resistant cloth 22 can push branches and gravel off the railway track surface to the ground.

[0034] In practice, when using the contact wire geometric parameter measuring instrument, personnel need to first clear away branches and gravel from the railway track before conducting the measurement work. This method is not only wasteful of manpower but also time. A better approach is to first attach the first threaded ring 17 onto the threaded post 16, then attach the L-shaped connecting plate 20 to the outside of the threaded post 16, so that the L-shaped connecting plate 20 is positioned between the two sets of limiting plates 19. At this point, the bottom of the L-shaped connecting plate 20 can rest on the top of the first threaded ring 17. Finally, attach the second threaded ring 18 onto the threaded post 16, and then... Tighten the screws so that the bottom of the second threaded ring 18 can press and fix the surface of the L-shaped connecting plate 20. When the pulley 2 is placed on the railway track, the wear-resistant cloth 22 at the bottom of the push block 21 can move above the railway track. At this time, the first threaded ring 17 can be rotated so that the first threaded ring 17 can slide downwards, thereby allowing the L-shaped connecting plate 20 and the wear-resistant cloth 22 to move downwards. When the bottom of the wear-resistant cloth 22 moves to a certain distance from the surface of the railway track, the second threaded ring 18 can be rotated downwards, thereby fixing the L-shaped connecting plate 20.

[0035] See Figure 1 , Figure 5 and Figure 6 It can be seen that when the pulley 2 rolls on the railway track, the pusher block 21 and the wear-resistant cloth 22 can push the branches and gravel on the surface of the railway track in front of it down, so that the branches and gravel on the surface of the railway track are not likely to affect the pulley 2, thus making the measurement results less likely to be affected, and no special personnel are required to clean it in advance, which can save time.

[0036] In summary, when using this intelligent contact network geometric parameter measuring instrument, the top of the stop block 14 can be flipped via the rotating shaft, allowing the bottom of the stop block 14 to be moved away from the outside of the moving plate 10 and rotated out through the through hole 13, so that the stop block 14 can fall on the top of the fixed block 8. By adjusting the height of the push rod 5, the operator can use the push rod 5 according to their own usage habits and needs, making the contact network geometric parameter measuring instrument smoother and more convenient to use, thus improving its measurement efficiency. When the pulley 2 rolls on the railway track, the push block 21 and the wear-resistant cloth 22 can push down the branches and gravel on the surface of the railway track in front, making it less likely for the branches and gravel on the surface of the railway track to affect the pulley 2, thus making the measurement results less likely to be affected, and no special personnel are required to clean it in advance, which can save time. The contents not described in detail in this description are existing technologies known to those skilled in the art.

[0037] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
