Description

Technical Field

[0001] This utility model relates to the field of railway engineering surveying equipment, and in particular to a railway rail length measuring trolley. Background Technology

[0002] A railway rail length measuring trolley is a specialized device used to measure the length of railway rails. It typically consists of a crossbeam, guide wheels, traveling wheels, and measuring wheels. The measuring wheels rotate to collect data and transmit it to data analysis equipment to calculate the rail length.

[0003] However, the existing railway rail length measuring trolley still has significant shortcomings:

[0004] On the one hand, the lack of an effective rail surface cleaning device means that sand and other debris on the rail surface can easily cause the traveling wheels and measuring wheels to slip and get stuck during the measurement process, seriously affecting the accuracy of the measuring wheel rotation data and increasing the error of the test results. On the other hand, the lack of a targeted sunshade structure means that when working outdoors, direct sunlight shines on the screen of the data analysis equipment, and strong light reflection interferes with data observation, making it difficult for operators to read the data clearly. This not only reduces work efficiency but also increases the risk of measurement data errors, greatly limiting the practicality and reliability of the distance measuring trolley in complex outdoor environments.

[0005] In response to this technical problem, this application proposes a railway rail length measuring trolley. Utility Model Content

[0006] The purpose of this invention is to address the shortcomings of existing technologies, such as the lack of rail cleaning devices and sunshade structures, which easily lead to large measurement errors and difficulty in data reading. This invention proposes a railway rail length measuring trolley that enables real-time cleaning of rail debris, reduces wheel slippage, and improves measurement accuracy. Simultaneously, it utilizes a screw-driven structure to link with a light-blocking plate, flexibly adjusting the angle to block sunlight, avoiding interference from strong light during data observation, and enhancing the practicality and reliability of outdoor operations.

[0007] To achieve the above objectives, the present invention provides the following technical solution:

[0008] A railway rail length measuring trolley includes a crossbeam. Guide wheels are installed at both the front and rear ends of the left side of the crossbeam, a traveling wheel is installed on the right side of the crossbeam, and a measuring wheel is installed at the bottom right end of the crossbeam. A push rod is connected to the top of the crossbeam via an installation assembly. An equipment support plate is provided on the front side of the push rod, and a data analysis device is provided on the top of the equipment support plate. A clamping plate is detachably connected to both ends of the crossbeam. The top of the clamping plates is connected to each other via a connecting frame. A second clamping plate is slidably connected to the bottom rear end of the connecting frame. A connecting block is fixedly connected to the bottom side of the outer wall of the second clamping plate and the first clamping plate. The connecting block is connected via a connecting assembly. An installation groove is opened at the front end of the top of the connecting frame. An installation seat is detachably connected to the inner wall of the installation groove. A scraper is connected to the installation seat via a fixing bolt. Limit blocks are slidably connected to the rear ends of both sides of the installation seat.

[0009] Furthermore, a support rod is fixedly connected to the top front end of the equipment tray, and a light-blocking plate is rotatably connected to the top end of the support rod on the camera side. Support rods are rotatably connected to the front ends of both the left and right sides of the light-blocking plate. The support rods are connected to the equipment tray through a drive assembly.

[0010] Furthermore, the mounting assembly includes a fixing base, which is connected to the crossbeam by bolts. A mounting plate is fixedly connected to the top center of the fixing base, and the mounting plate is connected to the push rod by a fixing bolt.

[0011] Furthermore, the bottom end of the push rod is rotatably connected to the mounting plate, and the mounting plate has multiple positioning holes on its right side.

[0012] Furthermore, the drive assembly includes a lead screw, which is rotatably connected to the inner walls of the left and right ends of the equipment tray. The rear end of the lead screw passes through the equipment tray and is fixedly connected to a knob. A slide is threadedly connected to the outer side of the lead screw, and the slide is rotatably connected to the bottom end of the support rod.

[0013] Furthermore, the connecting component includes a connecting ring, which is detachably connected to the connecting block. The bottom of the connecting ring has a slot that is adapted to the connecting block.

[0014] Furthermore, a spring is provided on the top edge of the connecting ring.

[0015] Furthermore, the connecting blocks are installed in a relatively opposite direction, and a level is provided at the top right end of the crossbeam.

[0016] This utility model has the following beneficial effects:

[0017] 1. In this utility model, the clamping and fixing of the rail by clamping plate one and clamping plate two, and the stable connection between the connecting ring and the connecting block, ensure that the scraper on the connecting frame cleans sand and gravel and other debris from the rail surface in real time during the movement of the distance measuring vehicle. This reduces slippage or jamming between the traveling wheel, measuring wheel and rail, significantly improves the accuracy of the measuring wheel rotation data, ensures the precision of the test results, and greatly enhances the practicality and reliability of the distance measuring vehicle in complex outdoor environments.

[0018] 2. In this utility model, through the adjustable angle light-blocking plate structure, the linkage between the lead screw, slide and support rod and the light-blocking plate can flexibly adjust the tilt according to the angle of sunlight, effectively blocking direct sunlight from shining on the screen of the data analysis equipment, avoiding strong light reflection interference, and solving the problem of inconvenient data observation during outdoor operations.

[0026] 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.

[0027] Reference Figures 1-3 An embodiment of this utility model provides a railway rail length measuring trolley, including a cross frame 1. Guide wheels 2 are installed at the front and rear ends of the left side of the cross frame 1, a traveling wheel 21 is installed on the right side of the cross frame 1, a measuring wheel 22 is installed at the bottom right end of the cross frame 1, a push rod 4 is connected to the top of the cross frame 1 through an installation component 3, an equipment support plate 5 is provided on the front side of the push rod 4, a data analysis device 6 is provided on the top of the equipment support plate 5, a clamping plate 11 is detachably connected to both the left and right ends of the cross frame 1, the top of the clamping plates 11 is connected to the top of the two clamping plates 11 through a connecting frame 12, a clamping plate 23 is slidably connected to the bottom rear end of the connecting frame 12, a connecting block 23 is fixedly connected to the bottom side of the outer wall of the clamping plate 11 and the connecting block 23 is connected through a connecting component 14, an installation groove 15 is opened at the front end of the top of the connecting frame 12, an installation seat 16 is detachably connected to the inner wall of the installation groove 15, a scraper 19 is connected to the installation seat 16 through a fixing bolt 2 18, and a limit block 17 is slidably connected to the rear ends of both the left and right sides of the installation seat 16.

[0028] Specifically, addressing the issue of sand and gravel on the rail surface affecting the movement of the ranging vehicle and the detection effect in existing devices, the following steps are taken: Clamping plate 11 is installed on the crossbeam 1, and sliding clamping plate 13 clamps and fixes the rail, ensuring the connecting frame 12 is stably installed above the rail. Then, connecting ring 1401 is engaged with connecting block 23. Rotating connecting ring 1401 to misalign its installation direction with connecting block 23 achieves initial fixation. The reaction force of the top spring 1403 causes connecting block 23 to engage with slot 1402, preventing accidental contact or rotation of connecting ring 1401 during operation. After the connecting frame 12 is securely installed, the mounting base 16 is inserted into the mounting groove 15. The spring inside the mounting base 16 pushes the sliding limit blocks 17 at both ends to lock into the left and right sides of the inner wall of the mounting groove 15 for fixation. Then, the scraper 19 is fixed to the mounting base 16 by the fixing bolt 2 18, so that the scraper 19 can clean the sand and gravel and other debris on the surface of the rail in front in real time when the ranging vehicle moves, reducing the slippage or jamming between the traveling wheel 21, measuring wheel 22 and the rail, thereby improving the accuracy of the rotation data of the measuring wheel 22 and ensuring the accuracy of the test results.

[0029] Reference Figures 2-5A support rod 7 is fixedly connected to the top front end of the equipment tray 5. A light-blocking plate 8 is rotatably connected to the top end of the support rod 7 on the camera side. Support rods 10 are rotatably connected to the front ends of both sides of the light-blocking plate 8. The support rods 10 are connected to the equipment tray 5 through the drive assembly 9. The mounting assembly 3 includes a fixing base 301, which is connected to the cross frame 1 by bolts. A mounting plate 302 is fixedly connected to the top middle of the fixing base 301. The mounting plate 302 is connected to the push rod 4 through a fixing bolt 303. The bottom end of the push rod 4 is rotatably connected to the mounting plate 302. Multiple positioning holes are opened on the right side of the mounting plate 302. The drive assembly 9 includes a lead screw 90. 1. The lead screw 901 is rotatably connected to the inner walls of the left and right ends of the equipment tray 5. The rear end of the lead screw 901 passes through the equipment tray 5 and is fixedly connected to a knob 902. The outer side of the lead screw 901 is threadedly connected to a slide block 903, which is rotatably connected to the bottom end of the support rod 10. The connecting assembly 14 includes a connecting ring 1401, which is detachably connected to the connecting block 23. The bottom of the connecting ring 1401 has a slot 1402 that is adapted to the connecting block 23. A spring 1403 is provided on the top edge of the connecting ring 1401. The connecting block 23 is installed in a relatively opposite direction. A level 20 is provided on the top right end of the crossbar 1.

[0030] Specifically, addressing the issue of glare from sunlight hindering data observation on the screen of the data analysis device 6 during outdoor operations, the knob 902 drives the lead screw 901 to rotate, causing the slide 903, threaded to the outside of the lead screw 901, to move back and forth. The slide 903 then displaces the rotating connection point at the bottom of the support rod 10. The support rod 10, through its rotating connection with the left and right front ends of the light-blocking plate 8, combined with the rotating connection between the support rod 7 and the top of the light-blocking plate 8, allows for angle adjustment of the light-blocking plate 8. This enables flexible adjustment of the tilt of the light-blocking plate 8 according to the angle of sunlight, effectively blocking direct sunlight from hitting the screen of the data analysis device 6 on top of the equipment support plate 5, avoiding strong light reflection interference, and improving the convenience of data observation in outdoor environments. Furthermore, the threaded transmission structure between the lead screw 901 and the slide 903 allows for fine adjustment of the angle of the light-blocking plate 8, making it more versatile.

[0031] Working principle: In use, firstly, clamping plate 11 is installed on the crossbeam 1, and sliding clamping plate 13 clamps and fixes the rail. The connecting ring 1401 engages with the connecting block 23, rotates in a staggered manner, and the reaction force of the spring 1403 completes the installation of the connecting frame 12. Then, the mounting base 16 is inserted into the mounting groove 15 and fixed by the limiting block 17. The scraper 19 is installed with the fixing bolt 18 to clean the surface of the rail. At the same time, rotating the knob 902 drives the lead screw 901 to rotate, causing the slide 903 to move back and forth. Through the linkage of the support rod 10 and the support rod 7, the angle of the light-blocking plate 8 is adjusted to block sunlight. Afterward, the operator pushes the distance measuring trolley with the push rod 4. The guide wheel 2 and the traveling wheel 21 on the crossbeam 1 assist in the movement, and the measuring wheel 22 measures the length of the rail. The measurement data is transmitted to the data analysis device 6 on the equipment tray 5. The operator can clearly observe the data through the adjusted light-blocking plate 8, and the level 20 on the top of the crossbeam 1 can help ensure the horizontal accuracy of the measurement process.

[0032] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model 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 utility model should be included within the protection scope of the present utility model.
