A rail profile grinding measurement auxiliary device

Abstract

This utility model discloses an auxiliary device for measuring the profile of a steel rail grinding process, belonging to the technical field of measurement auxiliary devices. It includes a steel rail, a traveling carriage mounted on the rail, a top plate with a detection mechanism on the top plate, and a fixed frame fixedly connected to the lower end of the top plate. A stabilizing mechanism is mounted on the fixed frame. The device uses a servo motor to drive a bidirectional screw to rotate until the drive rod on the moving block abuts against the guide plate on the lifting block. At this point, the sliding rod on the lower side of the moving block, under the action of a spring, presses against the follower wheel, making it tightly fit against the side of the steel rail. This, together with the traveling wheel, constrains the traveling carriage, reducing the risk of derailment. The bidirectional screw continues to be driven until the limit rod on the vertical plate abuts against the side of the steel rail. Simultaneously, the drive rod lifts the guide plate, raising the gripper to a tight abutment against the surface of the rail head. This achieves multiple layers of stable fixation, effectively avoiding possible displacement or vibration during the detection process and ensuring the accuracy of the measurement data.

Description

Technical Field

[0001] This utility model relates to the field of measurement auxiliary device technology, specifically to a rail grinding profile measurement auxiliary device. Background Technology

[0002] Steel rails are the main components of railway tracks. Their function is to guide the wheels of locomotives and rolling stock forward, bear the enormous pressure of the wheels, and transmit it to the sleepers. Steel rails must provide the wheels with a continuous, smooth, and least resistant rolling surface.

[0003] To ensure the stable use of rails, grinding the surface of the rails is the main way to extend their service life. The main purpose of the profile measuring device is to ensure that the cross-sectional shape of the rails meets the standards after grinding. That is, by using special measuring equipment, the curve, width and thickness of the rail surface are checked.

[0004] Because different types of rails have different web angles and base widths, and the rail webs of rails undergo wear and other localized deformations after prolonged use, the measuring device itself is prone to displacement or vibration during the measurement process, leading to data distortion. Therefore, this solution provides an auxiliary device for measuring the profile of a rail grinding process to address the aforementioned problems. Utility Model Content

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0007] A rail grinding profile measurement auxiliary device includes a rail, a traveling carriage mounted on the rail, a top plate on the traveling carriage, a detection mechanism mounted on the top plate, a fixed frame fixedly connected to the lower end of the top plate, and a stabilizing mechanism mounted on the fixed frame. The stabilizing mechanism includes a bidirectional screw rotatably mounted inside the fixed frame, a servo motor fixedly mounted at the front end of the fixed frame, the output shaft of the servo motor fixedly connected to the bidirectional screw, two sets of symmetrical moving blocks threaded onto the bidirectional screw, a vertical plate fixedly connected to the lower end of each set of moving blocks, a slidable follower wheel mounted on each vertical plate, and a liftable gripper mounted on the right side of the follower wheel.

[0008] Preferably, a slide rod is slidably connected to the vertical plate, and a rotating seat is fixedly connected to one end of the slide rod near the rail. The follower wheel is installed in the rotating seat, and an outer plate is fixedly connected to the other end of the slide rod.

[0009] A spring is fixedly connected between the outer plate and the vertical plate, and a spring is sleeved on the slide rod. A spring damper is provided on the lower side of the spring, and the two ends of the spring damper are fixedly connected to the vertical plate and the outer plate, respectively.

[0010] Preferably, the upper end of each movable block is fixedly connected to a limit rod, the lower end of the top plate is fixedly connected to a guide rail for sliding with the limit rod, and the bottom of the fixed frame is provided with a sliding fixing groove for sliding with the vertical plate.

[0011] Preferably, a drive rod is fixedly connected to the right end of each movable block, and two sets of symmetrical vertical rods are provided on the right side of the drive rod. The two ends of the two sets of vertical rods are fixedly connected to the top plate and the fixed frame, respectively, and a lifting block is slidably connected to each vertical rod.

[0012] The left end of each lifting block is fixedly connected to a guide plate for cooperating with the drive rod. A spring 2 sleeved on the vertical rod is fixedly connected between the lifting block and the top plate. Several sets of connecting rods are fixedly connected to the lower end of each lifting block. The lower end of the connecting rod passes through the fixed frame and is fixedly connected to a snap-fit ​​seat. A clamp is snapped into the snap-fit ​​seat. A fixing pin is inserted into the snap-fit ​​seat and the clamp.

[0013] Preferably, a fixed base is fixedly connected to both sides of the lower end of the top plate, and a traveling wheel is rotatably installed on the fixed base. A push-pull rod is fixedly installed on the upper right side of the top plate.

[0014] Preferably, the detection mechanism includes a slide plate slidably connected to a slide groove, a laser measuring instrument and a fixing plate are fixedly installed on the slide plate, a sleeve is fixedly connected to the fixing plate, a rotating motor is fixedly installed on the top plate on the right side of the sleeve, and a threaded rod is fixedly connected to the output shaft of the rotating motor, and the threaded rod is threadedly connected to the sleeve.

[0015] Compared with the prior art, this utility model proposes an auxiliary device for measuring the profile of rail grinding, which has the following beneficial effects:

[0016] This utility model is equipped with a stabilizing mechanism to ensure the stable operation and precise positioning of the traveling vehicle on the rails:

[0017] Stability during travel: A servo motor drives a bidirectional screw to rotate, causing the two moving blocks on either side to move towards each other until the drive rod on the moving block abuts against the guide plate on the lifting block. At this point, the vertical plate at the lower end of the moving block drives the sliding rod (under the action of spring one) to press the follower wheel, making it tightly fit against the side of the rail. In this state, the follower wheel, under the preload of spring one, works with the traveling wheel to restrain the traveling vehicle, effectively reducing the risk of derailment. At the same time, the detachable gripper installed on the right side of the follower wheel maintains a certain gap with the rail head surface, not hindering the normal movement of the traveling vehicle.

[0018] Fixation during inspection: When rail inspection is required, the servo motor drives the bidirectional screw to rotate again, pushing the moving block and its connected vertical plate and drive rod to move. The vertical plate moves until the limit rod on it abuts against the side of the rail, achieving initial clamping and limiting of both sides of the rail. At the same time, the drive rod lifts the guide plate, causing the lifting block to move upward. The lifting block, through the connecting rod and the locking seat, lifts the gripper until it is tightly abutting against the surface of the rail head. Thus, the traveling carriage achieves multiple stable fixation through the clamping of the rail side by the limit rod and the pressing of the gripper against the top surface of the rail head by the traveling wheels. This effectively avoids possible displacement or vibration during the inspection process, ensuring the accuracy of the measurement data. Attached Figure Description

[0029] The following description is intended to disclose the present invention so that those skilled in the art can implement it. The preferred embodiments described below are merely examples, and other obvious variations will occur to those skilled in the art.

[0030] Reference Figure 1 As shown, a rail grinding profile measurement auxiliary device includes a rail 1, a traveling vehicle 2 is mounted on the rail 1, the traveling vehicle 2 includes a top plate 201, a detection mechanism 4 is mounted on the top plate 201, a fixed frame 205 is fixedly connected to the lower end of the top plate 201, and a stabilizing mechanism 3 is mounted on the fixed frame 205.

[0031] Reference Figure 3-4 Specifically, in this embodiment, the stabilizing mechanism 3 includes a bidirectional screw 301 rotatably mounted in a fixed frame 205. A servo motor 302 is fixedly mounted at the front end of the fixed frame 205. The output shaft of the servo motor 302 is fixedly connected to the bidirectional screw 301. Two sets of symmetrical moving blocks 303 are threaded onto the bidirectional screw 301. A vertical plate 305 is fixedly connected to the lower end of each set of moving blocks 303. A slidable follower wheel 307 is provided on each vertical plate 305. A liftable gripper 3019 is provided on the right side of the follower wheel 307.

[0032] Reference Figure 3-4 Specifically, in this embodiment, a slide rod 306 is slidably connected to the vertical plate 305. A rotating seat is fixedly connected to one end of the slide rod 306 near the rail 1. A follower wheel 307 is rotatably installed in the rotating seat. An outer plate 308 is fixedly connected to the other end of the slide rod 306. A spring 309 sleeved on the slide rod 306 is fixedly connected between the outer plate 308 and the vertical plate 305. A spring damper 3010 is provided on the lower side of the spring 309. The two ends of the spring damper 3010 are fixedly connected to the vertical plate 305 and the outer plate 308, respectively.

[0033] Furthermore, the stabilizing mechanism 3 ensures the stable operation and precise positioning of the traveling vehicle 2 on the rail 1. Driven by the servo motor 302, the bidirectional screw 301 rotates, causing the two moving blocks 303 to move towards each other until the drive rod 3012 on the moving block 303 abuts against the guide plate 3016 on the lifting block 3014. At this point, the vertical plate 305 at the lower end of the moving block 303 drives the sliding rod 306 (under the action of spring 309) to press against the follower wheel 307, making it tightly fit against the side of the rail 1. In this state, the follower wheel 307, under the preload of spring 309, works with the traveling wheel 203 to constrain the traveling vehicle 2, effectively reducing the risk of derailment. Simultaneously, the detachable gripper 3019 installed on the right side of the follower wheel 307 maintains a certain gap with the rail head surface of the rail 1, not hindering the normal movement of the traveling vehicle 2.

[0034] Reference Figure 3-4Specifically, in this embodiment, the upper end of each movable block 303 is fixedly connected to a limiting rod 304, the lower end of the top plate 201 is fixedly connected to a guide rail 207 for sliding with the limiting rod 304, and the bottom of the fixed frame 205 is provided with a sliding fixing groove 206 for sliding with the vertical plate 305.

[0035] Reference Figure 3-4 Specifically, in this embodiment, a drive rod 3012 is fixedly connected to the right end of each movable block 303. Two sets of vertical rods 3013 are symmetrically arranged on the right side of the drive rod 3012. The two ends of the two sets of vertical rods 3013 are fixedly connected to the top plate 201 and the fixed frame 205 respectively. A lifting block 3014 is slidably connected to each vertical rod 3013.

[0036] The left end of each lifting block 3014 is fixedly connected to a guide plate 3016 for cooperating with the drive rod 3012. A spring 3015 sleeved on the vertical rod 3013 is fixedly connected between the lifting block 3014 and the top plate 201. Several sets of connecting rods 3017 are fixedly connected to the lower end of each lifting block 3014. The lower end of the connecting rod 3017 passes through the fixing frame 205 and is fixedly connected to a snap-fit ​​seat 3018. A clamp 3019 is snapped onto the snap-fit ​​seat 3018. A fixing pin 3020 is inserted into the snap-fit ​​seat 3018 and the clamp 3019.

[0037] Furthermore: When rail 1 needs to be inspected, the servo motor 302 drives the bidirectional screw 301 to rotate again, pushing the moving block 303 and the connected vertical plate 305 and drive rod 3012 to move. The vertical plate 305 moves until the limiting rod 3011 on it abuts against the side of rail 1, achieving initial clamping and limiting of both sides of rail 1. At the same time, the drive rod 3012 lifts the guide plate 3016, driving the lifting block 3014 to move upward. The lifting block 3014, through the connecting rod 3017 and the locking seat 3018, lifts the gripper 3019 to a tight abutment against the surface of the rail head of rail 1. Thus, the traveling carriage 2 achieves multiple stable fixation through the clamping of the side of rail 1 by the limiting rod 3011 and the pressing of the gripper 3019 against the top surface of the rail head by the traveling wheel 203, effectively avoiding possible displacement or vibration during the inspection process and ensuring the accuracy of the measurement data.

[0038] Reference Figure 2 Specifically, in this embodiment, a fixed seat 202 is fixedly connected to both sides of the lower end of the top plate 201, a traveling wheel 203 is rotatably mounted on the fixed seat 202, and a push-pull rod 208 is fixedly mounted on the upper right side of the top plate 201.

[0039] Reference Figure 5Specifically, in this embodiment, the detection mechanism 4 includes a slide plate 401 slidably connected to the slide groove 204. A laser measuring device 402 and a fixing plate 403 are fixedly installed on the slide plate 401. A sleeve 404 is fixedly connected to the fixing plate 403. A rotating motor 405 is fixedly installed on the top plate 201 on the right side of the sleeve 404. A threaded rod 406 is fixedly connected to the output shaft of the rotating motor 405. The threaded rod 406 is threadedly connected to the sleeve 404.

[0040] Furthermore, multiple stable fixation is achieved by clamping the side of the rail 1 with the limiting rod 3011 and pressing the top surface of the rail head with the gripper 3019 and the traveling wheel 203. After fixation, the threaded rod 406 is rotated by the rotating motor 405, which in turn drives the sleeve 404 to move on the threaded rod 406. This causes the sleeve 404 to move back and forth in the slide 204 with the sliding plate 401, allowing the laser measuring device 402 to move back and forth on the rail 1 to scan and accurately detect the rail 1.

[0041] The working principle of this utility model is as follows: When in use, the stabilizing mechanism 4 is activated, driving the bidirectional screw 301 to rotate via the servo motor 302. This causes the two moving blocks 303 on both sides to move towards each other until the driving rod 3012 on the moving block 303 abuts against the guide plate 3016 on the lifting block 3014. At this point, the vertical plate 305 at the lower end of the moving block 303 drives the sliding rod 306 (under the action of spring 309) to press the follower wheel 307, making it tightly fit against the side of the rail 1. In this state, the follower wheel 307, under the preload of spring 309, works with the traveling wheel 203 to jointly constrain the traveling carriage 2, effectively reducing the risk of derailment. Simultaneously, the detachable gripper 3019 installed on the right side of the follower wheel 307 maintains a certain gap with the rail head surface of the rail 1, not hindering the normal movement of the traveling carriage 2. Subsequently, the trolley can be driven to move on the rail 1 via the push-pull rod 208.

[0042] When rail 1 needs to be inspected, the servo motor 302 drives the bidirectional screw 301 to rotate again, pushing the moving block 303 and the connected vertical plate 305 and drive rod 3012 to move: the vertical plate 305 moves until the limiting rod 3011 on it abuts against the side of rail 1, realizing the initial clamping and limiting of both sides of rail 1; at the same time, the drive rod 3012 lifts the guide plate 3016, driving the lifting block 3014 to move upward. The lifting block 3014, through the connecting rod 3017 and the locking seat 3018, lifts the gripper 3019 to a tight abutment against the surface of the rail head of rail 1. Thus, the traveling vehicle 2 achieves multiple stable fixation by clamping the side of rail 1 with the limiting rod 3011 and by the gripper 3019 cooperating with the traveling wheel 203 to press against the top surface of the rail head. Then, the rail can be inspected by the inspection mechanism 4, effectively avoiding possible displacement or vibration during the inspection process and ensuring the accuracy of the measurement data;
