Detailed Implementation

[0017] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are for illustrative purposes only and are not intended to limit the scope of this utility model.

[0018] This utility model provides a laser track inspection and calibration device, the structure of which is as follows: Figure 1 As shown, it includes a vibration mechanism 100, a translation mechanism 200, a motion mechanism 300, and a loading mechanism 400. The vibration mechanism 100 is used to detachably fix two standard tracks 1 in parallel and horizontally, and can make the two standard tracks 1 vibrate up and down. The translation mechanism 200 can reciprocate linearly along the length direction of the standard guide rails. The motion mechanism 300 is connected to the translation mechanism 200 and can move freely in space. The loading mechanism 400 is connected to the motion mechanism 300 and is used to detachably fix the laser track detector 2 to be calibrated, and to position the two emitting ends of the laser track detector 2 directly above the two standard tracks 1, so that the laser contour 21 emitted from the two emitting ends of the laser track detector 2 covers the cross section of the standard track 1.

[0019] When calibrating the laser track inspector 2, two standard tracks 1 are first detachably and horizontally fixed to the vibration mechanism 100. Then, the laser track inspector 2 to be calibrated is detachably fixed to the loading mechanism 400, with the two emitting ends of the laser track inspector 2 positioned directly above the two standard tracks 1, so that the laser profile 21 emitted from the two emitting ends of the laser track inspector 2 covers the cross-section of the standard tracks 1. By operating the vibration mechanism 100, the two standard tracks 1 can vibrate up and down, simulating the working condition of a train moving up and down on the track due to pressure applied by the train. By operating the translation mechanism 200, the translation mechanism 200 can reciprocate linearly along the length of the standard guide rail. This causes the motion mechanism 300, the loading mechanism 400, and the laser track inspector 2 to reciprocate linearly along the length of the standard guide rail, simulating the relative displacement between the laser track inspector 2 and the track when the train is traveling on the track. By controlling the motion mechanism 300, the motion mechanism 300 can perform six degrees of freedom of motion, thereby causing the loading mechanism 400 and the laser track inspector 2 to perform six degrees of freedom of motion, simulating the multi-angle motion of the laser track inspector 2 relative to the track when the train is traveling on the track. This laser track inspector calibration device can simulate the motion of the actual vehicle body when simulating and calibrating the laser track inspector 2, that is, it can simulate the actual working conditions when the laser track inspector 2 is officially put into operation, ensuring the reliability of the test and improving the calibration accuracy.

[0020] As a preferred embodiment, please refer to Figure 1 The vibration mechanism 100 includes two components, which are arranged opposite to each other and spaced apart. Each of the two vibration mechanisms 100 is used to detachably fix a standard track 1. By setting the two vibration mechanisms 100 to detachably fix the two standard tracks 1, it is convenient to arrange the translation mechanism 200, the motion mechanism 300 and the loading mechanism 400 on the two vibration mechanisms 100. This ensures that the two emitting ends of the laser track detector 2 can be located directly above the two standard tracks 1, thereby ensuring that the laser contour 21 emitted from the two emitting ends of the laser track detector 2 covers the cross section of the standard track 1.

[0021] As a preferred embodiment, please refer to Figure 1 and Figure 2The vibration mechanism 100 includes a base plate 110, multiple sleeves 120, multiple rods 130, a platform 140, multiple first elastic elements 150, and a vibrating element 160. The base plate 110 is horizontally arranged, and each sleeve 120 is vertically arranged, with the bottom of each sleeve 120 fixedly connected to the base plate 110. The lower ends of each rod 130 are slidably disposed within each sleeve 120. The platform 140 is horizontally arranged and fixedly connected to the top of each rod 130. A standard track 1 is detachably fixed on the platform 140. Each first elastic element 150 is correspondingly sleeved onto each rod 130, and each first elastic element 160... The lower end of 50 is connected to each of the sleeves 120 in a corresponding manner. The upper end of each of the first elastic elements 150 is connected to the platform 140 to apply a vertical upward or downward force to the platform 140. The vibrating element 160 is connected to the platform 140 and can generate a vertical vibration force. When calibrating the laser track inspection 2, the vibrating element 160 is activated and can generate a vertical vibration force. Due to the elastic force of each of the first elastic elements 150, the platform 140 can vibrate up and down, thereby causing the standard track 1, which is detachably fixed to the platform 140, to vibrate up and down, simulating the working condition of a train moving up and down when the train applies pressure to the track.

[0022] As a preferred embodiment, please refer to Figure 2 The platform 140 has a placement groove 141 for embedding a standard track 1. The standard track 1 embedded in the placement groove 141 is interference-fitted with the groove wall of the placement groove 141, thereby limiting the standard track 1 through the placement groove 141 and realizing the detachable fixed connection between the standard track 1 and the platform 140.

[0023] As a preferred embodiment, please refer to Figure 2 The first elastic element 150 is a first spring.

[0024] In a preferred embodiment, the vibrating element 160 is a vibration motor, which can generate vibration when the vibration motor is started.

[0025] As a preferred embodiment, please refer to Figure 1 and Figure 3The translation mechanism 200 includes a bracket 210, at least one first guide rod 220, a lead screw 230, a translation seat 240, and a rotation drive 250. Each first guide rod 220 and the lead screw 230 is parallel and horizontally arranged, with both ends of each first guide rod 220 fixedly connected to the bracket 210. Both ends of the lead screw 230 are rotatably connected to the bracket 210. The translation seat 240 has at least one through hole and a screw hole, and is slidably fitted onto each first guide rod 220 through each through hole, and threadedly fitted onto the lead screw 230 through the screw hole. The motion mechanism 300 is connected to the translation seat 240, and the rotation drive 250... The output end of the actuator 250 is connected to one end of the lead screw 230 to drive the lead screw 230 to rotate. When the rotation drive 250 is activated, the output end of the rotation drive 250 can drive the lead screw 230 to rotate. Since the lead screw 230 is threadedly connected to the translation seat 240, and the translation seat 240 is limited and guided by each of the first guide rods 220, the translation seat 240 can perform horizontal reciprocating linear motion, thereby driving the motion mechanism 300, the loading mechanism 400, and the laser track inspector 2 to reciprocate linearly along the length direction of the standard guide rail, simulating the situation where the laser track inspector 2 and the track undergo relative displacement when the train is traveling on the track.

[0026] In a preferred embodiment, the rotation drive component 250 can be a motor of a suitable model directly connected to one end of the lead screw 230, or it can be a gear set or belt set indirectly connected to one end of the lead screw 230.

[0027] As a preferred embodiment, please refer to Figure 1 The motion mechanism 300 is located between two standard tracks 1, and the distance between the motion mechanism 300 and the two standard tracks 1 is equal, ensuring that the two emitting ends of the laser track detector 2 can be located directly above the two standard tracks 1 respectively, thereby ensuring that the laser contour 21 emitted from the two emitting ends of the laser track detector 2 covers the cross section of the standard track 1.

[0028] As a preferred embodiment, please refer to Figure 1 and Figure 3The motion mechanism 300 includes a chassis 310, six lower mounting seats 320, a top plate 330, six upper mounting seats 340, and six telescopic drive members 350. The chassis 310 is horizontally arranged and connected to the translation mechanism 200. The six lower mounting seats 320 are arranged in pairs, with three pairs arranged in a circular array and fixedly connected to the chassis 310. The top plate 330 is horizontally arranged directly above the chassis 310. The upper mounting seats 340 are arranged in pairs, with three pairs arranged in a circular array and fixedly connected to the top plate 330. The three pairs of upper mounting seats 340 and the three pairs of lower mounting seats 320 are staggered, and their projections in the horizontal plane form a circular array. The fixed ends of the six telescopic drive members 350 are connected to each... The lower mounting base 320 is connected to each other by a ball joint, and the telescopic ends of the six telescopic drive members 350 are connected to each of the upper mounting bases 340 by a ball joint. The loading mechanism 400 is connected to the top plate 330. When the telescopic lengths of the six telescopic drive members 350 are different, the top plate 330 can achieve linear movement along the X-axis (left-right translation), linear movement along the Y-axis (forward-backward translation), linear movement along the Z-axis (up-down translation), rotation along the X-axis (rolling), rotation along the Y-axis (pitch), and rotation along the Z-axis (yaw). This drives the loading mechanism 400 and the laser track detector 2 to perform six degrees of freedom motion, simulating the multi-angle motion of the laser track detector 2 relative to the track when the train is moving on the track.

[0029] In a preferred embodiment, the telescopic drive component 350 is selected from a suitable type of cylinder and is directly connected to the upper mounting base 340 and the lower mounting base 320.

[0030] As a preferred embodiment, please refer to Figure 3 The chassis 310 is fixedly connected to the translation seat 240.

[0031] As a preferred embodiment, please refer to Figure 3 and Figure 5 The loading mechanism 400 includes a loading frame 410 and multiple fixing components 420. The loading frame 410 is used to place the laser track detector 2 to be calibrated. Each of the fixing components 420 is detachably and fixedly connected to the loading frame 410 and the laser track detector 2. The loading frame 410 carries the laser track detector 2 to be calibrated. By detachably and fixedly connecting each of the fixing components 420 to the loading frame 410 and the laser track detector 2, the assembly and disassembly of the laser track detector 2 can be realized.

[0032] As a preferred embodiment, please refer to Figure 3 and Figure 5 The loading rack 410 has a loading slot 411 for placing the laser track detector 2. The width of the loading slot 411 is equal to the width of the laser track detector 2 to limit the width of the laser track detector 2. Both ends of the loading slot 411 in the length direction are open so that the two emitting ends of the laser track detector 2 extend out of the loading slot 411 through the openings at both ends. Since the width of the loading slot 411 is equal to the width of the laser track detector 2, the width of the laser track detector 2 can be limited to prevent it from moving along its own width direction. Furthermore, the fixing effect of each fixing component 420 prevents the laser track detector 2 from moving along its own length and vertical direction.

[0033] As a preferred embodiment, please refer to Figure 4 and Figure 5 The laser track detector 2 has multiple mounting holes 22 on its two opposite sidewalls in the width direction. The loading frame 410 has multiple insertion holes 412 that communicate with the loading groove 411. When the laser track detector 2 is placed in the loading groove 411, each mounting hole 22 on the laser track detector 2 communicates with each insertion hole 412 in a one-to-one correspondence. Each fixing component 420 includes a plug 421 and a second elastic element 422. Each plug 421 slides through each insertion hole 412 in a one-to-one correspondence. The second elastic element 422 connects the loading frame 410 and the plug 421, so that the... The inner end of the plug 421 is inserted into the mounting hole 22 on the laser track 2. When the laser track 2 needs to be installed, each plug 421 is removed from the mounting hole 22 on the laser track 2, and then the laser track 2 is placed in the loading slot 411. Each plug 421 is released, and the inner end of each plug 421 is inserted into the mounting hole 22 on the laser track 2 under the elastic force of the corresponding second elastic element 422, thereby fixing the laser track 2. The structure of the fixing component 420 can realize the quick assembly and disassembly of the laser track, improving the calibration efficiency of the laser track 2.

[0034] As a preferred embodiment, please refer to Figure 6 and Figure 7 The plug-in 421 includes a plug shaft 4211 and an end plate 4212. The plug shaft 4211 slides through the plug hole 412. The end plate 4212 is fixedly connected to the outer end of the plug shaft 4211. The second elastic member 422 connects the loading frame 410 and the end plate 4212 so that the inner end of the plug shaft 4211 is inserted into the mounting hole 22 on the laser track inspector 2. The end plate 4212 is provided to facilitate the connection of the second elastic member 422.

[0035] As a preferred embodiment, please refer to Figure 6 and Figure 7 The second elastic element 422 is a second spring.

[0036] As a preferred embodiment, please refer to Figure 6 and Figure 7 Each of the fixing components 420 further includes a sleeve 423 and a locking pin. Each sleeve 423 is respectively disposed on both sides of the loading groove 411 in the width direction and communicates with each of the insertion holes 412. Each plug-in 421 slides through each sleeve 423. Each plug-in 421 has a locking hole 4213. Each sleeve 423 has a first mating hole 4231 and a second mating hole 4232. The first mating hole 4231 is close to the loading groove 411, and the second mating hole 4232 is away from the loading groove 411. When the inner end of the plug-in 421 is inserted into the mounting hole 22 on the laser track 2, the first mating hole 4231 and the locking hole 4213 communicate with each other. The locking pin is inserted into the first mating hole 4231 and the locking hole 4213 to lock the plug-in 421. When the inner end of the plug-in 421 is removed from the mounting hole 22 on the laser track 2, the second mating hole 4232... The locking pin is inserted into the second docking hole 4232 and the locking hole 4213 to lock the plug-in 421. When the laser track inspector 2 needs to be installed, each plug-in 421 is moved out of each mounting hole 22 on the laser track inspector 2 until the second docking hole 4232 and the locking hole 4213 are connected. The locking pin is then inserted into the second docking hole 4232 and the locking hole 4213 to lock the plug-in 421. The laser track inspector 2 is then placed in the loading slot 411. Each locking pin is then moved out of the corresponding second docking hole 4232 and the locking hole 4213 to release the locking of the plug-in 421. The plug-in 421 is then released, and the inner end of each plug-in 421 is inserted into each mounting hole 22 on the laser track inspector 2 under the elastic force of the corresponding second elastic element 422. The assembly of the laser track inspector 2 can be easily completed by one person without the need for multiple people to operate.

[0037] As a preferred embodiment, please refer to Figure 6 and Figure 7 The insertion shaft 4211 slides through the sleeve 423, and the sleeve 423 can guide the insertion shaft 4211.

[0038] As a preferred embodiment, please refer to Figure 6 and Figure 7 The locking hole 4213 is provided on the insert shaft 4211.

[0039] As a preferred embodiment, please refer to Figure 6 and Figure 7 Each of the fixing components 420 further includes at least one second guide rod 424. Each second guide rod 424 is respectively disposed on both sides of the loading groove 411 in the width direction and is fixedly connected to the loading frame 410. The end plate 4212 is slidably sleeved on each of the second guide rods 424. The second elastic member 422 is sleeved on the second guide rod 424. The cooperation between the second guide rod 424 and the guide tube can limit the insertion 421 and prevent the insertion 421 from rotating. It can also guide and limit the second elastic member 422.

[0040] To better understand this utility model, the following is combined with... Figure 1 - Figure 7 The working principle of the technical solution of this utility model will be described in detail below: When calibrating the laser track inspector 2, firstly, two standard tracks 1 are respectively embedded into the placement slots 141 on the two platforms 140. The standard tracks 1 embedded in the placement slots 141 are interference-fitted with the slot walls of the placement slots 141, thereby limiting the standard tracks 1 through the placement slots 141 and realizing the detachable fixed connection between the standard tracks 1 and the platforms 140. Then, the laser track inspector 2 is placed in the loading slot 411, and each of the locking pins is removed from the corresponding second mating hole 4232 and the locking hole 4213 to release the locking of the plug 421. The plugs 421 are then released, and the inner ends of each plug 421 are aligned under the elastic force of the corresponding second elastic element 422. The mounting holes 22 on the laser track 2 should be inserted to fix the laser track 2. The structure of the fixing component 420 allows for quick assembly and disassembly of the laser track, improving the calibration efficiency of the laser track 2. After the laser track 2 is fixed, the two emitting ends of the laser track 2 are respectively located directly above the two standard tracks 1, thus ensuring that the laser profile 21 emitted from the two emitting ends of the laser track 2 covers the cross-section of the standard track 1. The vibrating element 160 is activated, and the vibrating element 160 can generate vertical vibration force. Due to the elastic force of each of the first elastic elements 150, the platform 140 can vibrate up and down, thereby causing the standard track 1, which is detachably fixed to the platform 140, to vibrate up and down. Vibration simulates the condition where a train moves up and down on a track due to pressure exerted by the train. The rotation drive 250 is activated, and its output drives the lead screw 230 to rotate. Since the lead screw 230 is threadedly connected to the translation seat 240, and the translation seat 240 is guided by the limiting action of each of the first guide rods 220, it can perform horizontal reciprocating linear motion. This causes the motion mechanism 300, the loading mechanism 400, and the laser track inspector 2 to reciprocate linearly along the length of the standard guide rail, simulating the relative displacement between the laser track inspector 2 and the track when the train is moving on the track. When the extension lengths of the six telescopic drive components 350 are not... Simultaneously, the top plate 330 can achieve linear movement along the X-axis (left-right translation), linear movement along the Y-axis (forward-backward translation), linear movement along the Z-axis (up-down translation), rotation along the X-axis (rolling), rotation along the Y-axis (pitch), and rotation along the Z-axis (yaw), thereby driving the loading mechanism 400 and the laser track inspector 2 to perform six degrees of freedom motion, simulating the multi-angle movement of the laser track inspector 2 relative to the track when the train is traveling on the track. This laser track inspector calibration device can simulate the motion of the actual vehicle body when conducting simulation tests and calibrations on the laser track inspector 2.This means it can simulate the actual working conditions when the laser track inspection system is officially launched, ensuring the reliability of the test and improving the calibration accuracy.

[0041] The laser track calibration device provided by this utility model has the following beneficial effects: (1) Place the laser track detector 2 in the loading slot 411, loosen each of the plugs 421, and insert the inner ends of each plug 421 into the mounting holes 22 on the laser track detector 2 under the elastic force of the corresponding second elastic member 422, thereby fixing the laser track detector 2. The structure of the fixing component 420 can realize the quick assembly and disassembly of the laser track component, thereby improving the calibration efficiency of the laser track detector 2. (2) When the laser track inspector 2 needs to be installed, each of the plug-in 421 is moved out of the mounting holes 22 on the laser track inspector 2 until the second docking hole 4232 and the locking hole 4213 are connected to each other. The locking pin is inserted into the second docking hole 4232 and the locking hole 4213 to lock the plug-in 421. Then the laser track inspector 2 is placed in the loading slot 411. Then each of the locking pins is moved out of the corresponding second docking hole 4232 and the locking hole 4213 to release the locking of the plug-in 421. The plug-in 421 is released. The inner end of each plug-in 421 is inserted into the mounting holes 22 on the laser track inspector 2 under the elastic force of the corresponding second elastic element 422. No multiple people are required to operate. One person can easily complete the assembly of the laser track inspector 2. (3) This laser track inspection calibration device can simulate the movement of the actual vehicle body when conducting simulation tests and calibration of the laser track inspection 2, that is, it can simulate the actual working conditions when the laser track inspection 2 is officially put into operation, thus ensuring the reliability of the test and improving the calibration accuracy.
