Description

Technical Field

[0001] The present invention relates to the technology of detection equipment, and particularly to a length measurement device for rail detection. Background Art

[0002] When a train runs on a track, due to the rolling, traction, braking of the wheels and the action of the current seamless line temperature stress, the rail will produce longitudinal displacement, that is, rail creep. If the amount of rail creep is too large, the rail cannot generate large tensile stress and compressive stress, and in severe cases, it may cause rail breakage or buckling accidents, affecting the safety of train operation.

[0003] The length measurement device for rail detection is mainly used in railway maintenance and repair to ensure that the length and state of the rail meet the standards and avoid safety problems caused by length changes or damages.

[0004] In the Chinese invention patent with the publication number of CN117968618B, a rail straightness detection device is disclosed. In this rail straightness detection device, when the rail is being transferred, the movable support wheels are in the middle position, and the movable support wheels abut against the web of the rail, thus preventing the rail from tipping during the transfer process; when the rail is being detected under the straightness detection unit; during the rising process of the fixed lifting unit, it drives the movable bracket to slide along the movable sliding shaft, causing the movable support wheels to move to both sides. After the fixed lifting unit contacts the rail, the transfer surface between the rail and the conveying roller path is separated; then the straightness detection unit conducts a contact straightness detection on the rail top.

[0005] When the existing equipment is in use, the accuracy of manual detection is easily affected by the proficiency and state of the detection personnel. Especially after working for a long time, it is easy to get tired, increasing the error rate during the measurement process. At the same time, in order to improve the measurement accuracy, the laser rangefinder sometimes needs to measure multiple times at different points on the rail, thus requiring continuous position adjustment. Due to the poor overall flexibility, the detection efficiency is greatly reduced, and when fixing after the adjustment is completed, the whole is prone to fluctuations, thus affecting the subsequent detection results. Therefore, a length measurement device for rail detection has been developed. Summary of the Invention

When the driving member 24 is started, it synchronously drives the rotating cylinder 25 provided at its output end to rotate. At the same time, when the rotating cylinder 25 rotates, it drives the first arc groove 251 and the second arc groove 252 provided on its outer surface to rotate, and the baffle 23 supports the rotating cylinder 25.

[0044] Specifically, the positioning shaft 26 is supported by a connecting block. Meanwhile, when the rotating cylinder 25 rotates, it cooperates with the second arc-shaped groove 252 formed on its outer surface to drive the swing plate 261 to swing. The end of the swing plate 261 is connected to the end of the positioning shaft 26, thereby driving the positioning shaft 26 to rotate.

[0045] Further, an adjusting plate 27 is provided at one end of the positioning shaft 26 away from the swing plate 261. A supporting plate 271 is provided at one end of the adjusting plate 27. A positioning rod 272 is provided at the end of the supporting plate 271. A roller 273 is provided at the end of the positioning rod 272. The outer surface of the roller 273 is in contact with the outer surface of the track 1.

[0046] Specifically, when the positioning shaft 26 rotates, it synchronously drives the adjusting plate 27 provided at its end to rotate. When the adjusting plate 27 rotates, it drives the supporting plate 271 provided at its end to move. Meanwhile, it cooperates with the positioning rod 272 to drive the roller 273 to move, so that the roller 273 moves to a suitable position.

[0047] Further, a movable block 28 is slidably installed at one end of the adjusting plate 27 away from the supporting plate 271. A guiding groove 281 is formed at the end of the movable block 28.

Meanwhile, a pressing block 283 is provided at the end of the moving rod 282.

[0048] Specifically, when the adjusting plate 27 rotates, it drives the movable block 28 at the end away from the supporting plate 271 to move and drives the movable block 28 to move, thereby synchronously driving the moving rod 282 provided at the upper end of the movable block 28 to move. Since the pressing block 283 is provided at the end of the moving rod 282, the track 1 is fixed by the pressing block 283.

[0049] Further, a limiting plate 29 is slidably installed on the outer surface of the moving rod 282. A slider 291 is provided at the middle position of the end of the limiting plate 29. The outer surface of the slider 291 is slidably connected to the inner wall of the first arc-shaped groove 251. Meanwhile, a movable rod 292 is provided on the outer surface of the limiting plate 29. Both ends of the movable rod 292 are fixedly connected to the inner wall of the baffle 23.

[0050] Specifically, the slider 291 at the end of the limiting plate 29 is slidably connected to the inner wall of the first arc-shaped groove 251, thereby driving the limiting plate 29 to move. The limiting plate 29 is limited by the movable rod 292, so that when the limiting plate 29 moves, it will not be interfered.

A convex block 274 is provided at the end of the roller 273, and a push plate 284 is provided at the end of the pressing block 283 at the same time, and the outer surface of the push plate 284 is attached to the outer surface of the convex block 274.

[0052] Specifically, the track 1 is locked by the cooperation of the extrusion block 211 and the pressing block 283, so that no shaking occurs during detection. At the same time, when fixing, the convex block 274 is pressed by the push plate 284 to keep the roller 273 stable as a whole.

[0053] Further, a positioning assembly 3 is assembled on the upper end of the docking block 22, and the measuring device is fixed by the positioning assembly 3. The positioning assembly 3 includes a clamping plate 31 connected to the docking block 22, a support column 33 is provided at the end of the clamping plate 31, and a bottom plate 34 is provided at the end of the support column 33. A telescopic member 32 is provided at the middle position of the upper end of the clamping plate 31, and the output end of the telescopic member 32 penetrates and extends to the other end of the bottom plate 34.

[0054] Specifically, the telescopic member 32 is a device with a telescopic function such as an electric telescopic rod and is connected to an external control device. At the same time, the bottom plate 34 is supported by the support column 33.

[0055] An annular block is provided at the lower end of the clamping plate 31, and the docking block 22 is docked through the annular block, so that positioning assemblies 3 of different specifications can be replaced according to actual conditions to make it suitable for different scenarios.

[0056] Further, a fixing cylinder 35 is provided on the upper end of the bottom plate 34. A tapered block 36 is slidably installed on the inner wall of the fixing cylinder 35, and the lower end of the tapered block 36 is connected to the output end of the telescopic member 32. A plurality of groups of power grooves 354 are uniformly formed on the outer surface of the fixing cylinder 35, and a power rod 37 is slidably installed on the inner wall of the power groove 354. The end of the power rod 37 is slidably connected to the outer surface of the tapered block 36.

[0057] Specifically, when the telescopic member 32 is started, the tapered block 36 provided at its output end is synchronously driven to move. Since the end of the power rod 37 is attached to the outer surface of the tapered block 36, when the tapered block 36 moves, the power rod 37 is extruded, so that the power rod 37 moves outward along the power groove 354 and pushes the clamping block 38 rotatably installed on the fixing cylinder 35 to rotate.

[0058] Further, a clamping block 38 corresponding to the power groove 354 is rotatably installed on the outer surface of the fixing cylinder 35. A limiting groove 351 is formed in the upper end of the outer surface of the fixing cylinder 35, and an elastic member 352 is provided on the inner wall of the limiting groove 351. At the same time, an extension rod 353 is slidably installed on the inner wall of the limiting groove 351, and the end of the extension rod 353 is connected to the end of the elastic member 352.

[0059] Specifically, when the clamping block 38 rotates, the laser detection device placed on the fixed cylinder 35 is locked to ensure that the laser device does not shake during operation. And when the entire device moves, the laser device is removed first, and after moving to a suitable position, the laser device is assembled again to reduce the risk of terrible damage to the laser device.

[0060] The elastic member 352 and the extension rod 353 on the inner wall of the limiting groove 351 are attached to the outer surface of the clamping block 38, so that after the conical block 36 returns to its initial position, the elastic member 352 and the extension rod 353 push the clamping block 38 to rotate, thereby separating the clamping block 38 from the laser device. The elastic member 352 is an elastic component such as a spring.

[0061] The control device can select a single-chip microcomputer as the control end. In this embodiment, the single-chip microcomputer is a typical embedded microcontroller (Micro controller Unit), which is composed of an arithmetic unit, a controller, a memory, input and output devices, etc., and is equivalent to a mini computer. Compared with the general-purpose microprocessor used in personal computers, it emphasizes more on self-supply (without external hardware) and cost savings. Its greatest advantage is its small size, which can be placed inside the instrument, but its storage capacity is small, the input and output interfaces are simple, and the function consumption is low.

[0062] Only some exemplary embodiments of the present invention have been described by way of illustration above. Undoubtedly, for those of ordinary skill in the art, the described embodiments can be modified in various different ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and description are illustrative in nature and should not be construed as limiting the protection scope of the claims of the present invention.
