Description

Technical Field

[0001] This invention belongs to the field of track gauge testing technology, and more specifically, relates to a testing device and method for testing the service life of track gauges. Background Technology

[0002] The track gauge is a core measuring instrument for measuring the geometric parameters of railway tracks. It is widely used in railway track laying, inspection, and daily maintenance. It can accurately detect key parameters such as track gauge, level, and check intervals for straight lines, curves, and turnouts. Its measurement accuracy is directly related to the safety of train operation. In particular, high-speed railways have more stringent requirements for the accuracy control of the track gauge. During field use, the track surface will wear down due to repeated contact with the rails. At the same time, the horizontal movement of the track gauge on the rail surface after the handle is released will also cause wear on the components. If the wear exceeds the threshold, it will directly affect the measurement accuracy. Therefore, the service life detection and wear assessment of the track gauge is an important part of railway track maintenance and a key prerequisite for ensuring the measurement accuracy of the track gauge and extending its effective service life.

[0003] Currently, the testing of track gauges mainly focuses on periodic verification and accuracy calibration. The industry already has relevant testing methods such as wear resistance testing and fatigue life testing, which can evaluate wear and durability performance through the reciprocating motion of the probe and tens of thousands of cycles of key components. At the same time, some testing devices attempt to simulate the actual use of track gauges. However, the existing testing of track gauge service life is mostly based on single-dimensional wear testing, and a comprehensive simulation system for the combined wear of vertical contact and horizontal movement in field use has not yet been formed. Moreover, some testing operations still rely on manual control of the action process, and can only complete the basic wear assessment through simple cyclic testing. The reproduction of the action sequence and stress state of track gauges in actual use is low. Summary of the Invention

[0004] To address the aforementioned deficiencies or improvement needs of existing technologies, this invention provides a testing device for detecting the service life of track gauges. A vertical lifting mechanism, installed at the top center of the outer side of the frame, drives the detection component and track gauge to move vertically. A horizontal lifting mechanism, installed on the top surface of the side center of the frame, pushes the track gauge to move horizontally. The detection component, installed in the middle of the track gauge, assists in both vertical and horizontal movement while simultaneously returning the track gauge to its original position. These components work together to complete the entire lifespan detection process of the testing device.

[0005] To achieve the above objectives, according to a first aspect of the present invention, a detection device for detecting the service life of a track gauge is provided, comprising: The main structure of the detection device consists of a frame, a vertical lifting mechanism bolted to the middle of the top of the outer side of the frame, a horizontal lifting mechanism located on the top surface of the middle side of the frame, and a detection component bolted to the middle of the gauge. The frame includes a bottom frame as the main structure of the frame, top beams on both sides of the top of the bottom frame, cross beams at the middle position of the top of both sides of the bottom frame, and a top frame connected to the middle of the cross beams by welding. The detection assembly includes a front clamping device as the main structure of the detection assembly, an upper clamping device located on the top of the outer side of the front clamping device, movable joints bolted to the top of both sides of the upper clamping device, and movable rotating wheels connected to the movable joints by a connecting rod. The movable rotating wheels can rotate freely.

[0006] Furthermore, shock-absorbing pads are installed at the top and bottom connections of the top beam to reduce vibrations generated during the movement of the gauge ruler.

[0007] Furthermore, the vertical lifting mechanism includes a vertical mounting plate, a push rod cylinder, and a vertical top block, with the push rod cylinder connected to the detection component by a rubber rope.

[0008] Furthermore, the lateral lifting mechanism includes a push rod cylinder and a lateral lifting block, the lateral lifting block being made of rubber material.

[0009] Furthermore, the movable joint is a joint mechanism consisting of two independently movable segments.

[0010] Furthermore, the frame also includes an electrical control assembly connected to the outer frame of the bottom frame and located inside the bottom frame, as well as rubber pads inserted into the bottom of both sides of the top frame.

[0011] Furthermore, the electrical control components include a PLC control module, a pneumatic control module, a position detection module, a detection and counting module, and a power supply and signal transmission module. The PLC control module uses a PLC controller to control the output pressure of the multi-channel pneumatic control module.

[0012] Furthermore, the detection component also includes a display device located at the bottom side of the front clamping device.

[0013] Furthermore, the display device is equipped with a position detection counter to record the number of times the track gauge completes its movement.

[0014] According to a second aspect of the present invention, a method of using a detection device for detecting the service life of a track gauge is provided, comprising: S100: Connect the power supply and pneumatic power source of the detection device, check whether the signal transmission of the PLC control module inside the electrical control component is normal, and confirm that the extension and retraction of the vertical lifting mechanism and the horizontal lifting mechanism are smooth and without jamming. S200: Then, the gauge to be tested is smoothly clamped in the designated position of the testing device to ensure that the track surface of the gauge is in close contact with the contact part of the testing device. S300: Through the operation interface of the electronic control component, the pressure output value of the pneumatic control module inside the electronic control component is set according to the model of the gauge, the actual working conditions on site and the requirements of the testing standards, so that the action force of the vertical lifting mechanism and the horizontal lifting mechanism are consistent with the force state used on site. S400: After confirming the preset action logic program in the PLC control module inside the electrical control component, and after the parameters are set and verified to be correct, the electrical control component issues a start command to start the automatic detection process of the track gauge's service life. S500: After the detection device is started, the horizontal lifting mechanism releases the gripper on the gauge ruler, completing the preliminary action of horizontal release. The vertical lifting mechanism extends and retracts upward, driving the gauge ruler to complete the lifting action, simulating the separation process of the gauge ruler and the rail in actual use. S600: Then the lateral lifting mechanism moves again, pushing the gauge ruler to move horizontally on the contact surface, simulating the horizontal sliding wear of the gauge ruler after the handle is released on site. S700: Repeat the above action process to achieve continuous cyclical wear simulation. Combined with the detection time, record the appearance of the gauge at different numbers of action cycles.

[0015] In summary, compared with the prior art, the above-described technical solutions conceived by this invention can achieve the following beneficial effects: 1. The detection device of the present invention uses a vertical lifting mechanism installed at the top center of the outer side of the frame to drive the detection component and the track gauge to move vertically, and a horizontal lifting mechanism installed on the top surface of the middle side of the frame to push the track gauge to move horizontally. The detection component installed in the middle of the track gauge assists in the vertical and horizontal movement of the track gauge and returns the track gauge to its original position. The above components cooperate with each other to complete the life detection action of the entire detection device.

[0016] 2. The frame of the present invention completes the installation of the lateral lifting mechanism, the track gauge and the detection components by means of the crossbeam installed at the middle position of the top of both sides of the bottom frame. The lifting mechanism is installed by means of the top frame connected to the middle of the crossbeam. Rubber pads are inserted into the bottom of both sides of the top frame to avoid collisions during the movement of the track gauge. The automated operation of the entire detection device is controlled by multiple modules inside the electronic control component.

[0017] 3. The detection component of the present invention, through a front clamping device with a clamping ring structure, locks the detection component onto the gauge and follows the movement of the gauge. Through two joint mechanisms formed by the movable joint and the movable wheel, it moves in close contact with the movement of the gauge and completes the circumferential rotation of the outer contour of the gauge, thereby completing the detection of the gauge life. The number of times the gauge completes the movement is recorded by a display device with an internal position detection counter as the gauge life. Attached Figure Description

[0025] This invention provides a testing device for detecting the service life of track gauges, such as... Figure 1 , Figure 2 , Figure 3As shown, the device includes a frame 1, a vertical lifting mechanism 2, a horizontal lifting mechanism 3, a gauge 4, and a detection assembly 5. The frame 1 serves as the main structure of the detection device, supporting other components. The vertical lifting mechanism 2 is bolted to the top center of the outer side of the frame 1. Specifically, the vertical lifting mechanism 2 is connected to the top center of the top outer side of the top frame 15 in the frame 1. The horizontal lifting mechanism 3 is installed on the top surface of the side of the frame 1. Specifically, the horizontal lifting mechanism 3 is connected to the outer middle of the two crossbeams 14 in the frame 1. The gauge 4 is installed in the middle of the frame 1. Specifically, the gauge 4 is connected to the middle of the two crossbeams 14 in the frame 1. The horizontal lifting mechanism 3 is located outside the gauge 4. The detection assembly 5 is bolted to the middle of the gauge 4. Specifically, the gauge 4 passes through the detection assembly 5, and the detection assembly 5 is located directly below the vertical lifting mechanism 2. The vertical lifting mechanism 2 includes... The system includes a vertical mounting plate, a push rod cylinder, and a vertical top block. The push rod cylinder is connected to the detection component 5 by a rubber rope. The vertical top block is made of rubber. The vertical lifting mechanism 2 drives the movable joint 56 and movable wheel 57 in the detection component 5 to move up and down, thereby driving the track gauge 4 to move up and down. The vertical lifting mechanism 2 is used to control the vertical movement of the track gauge 4 to simulate a scenario in which the track gauge 4 is used. The horizontal lifting mechanism 3 includes a push rod cylinder and a horizontal top block. The horizontal top block is not directly connected to the track gauge 4. The horizontal top block is made of rubber. After the vertical lifting mechanism 2 drives the detection component 5 to complete the downward movement, the horizontal lifting mechanism 3 pushes the track gauge 4 forward to simulate a scenario in which the track gauge 4 is used. After the horizontal lifting mechanism 3 returns to its original position, the track gauge 4 returns to its original position through its own track gauge outer contour 52, thus completing a complete set of life detection actions for the detection device. The detection component 5 has built-in contour-designed joints and wheels to cooperate with the movement of the track gauge 4 and simultaneously return the track gauge 4 to its original position. The detection device of the present invention uses a vertical lifting mechanism installed at the top center of the outer side of the frame to drive the detection component and the track gauge to move vertically. A horizontal lifting mechanism installed on the top surface of the middle side of the frame pushes the track gauge to move horizontally. The detection component installed in the middle of the track gauge assists in the vertical and horizontal movement of the track gauge and returns the track gauge to its original position. The above components work together to complete the life detection operation of the entire detection device.

[0026] Specifically, such as Figure 1 , Figure 2 , Figure 6As shown, the frame 1 includes a base frame 11, an electrical control assembly 12, a top beam 13, a crossbeam 14, a top frame 15, and rubber pads 16. The base frame 11 serves as the main structure of the frame 1 and is made of aluminum alloy to reduce the overall weight of the detection device. The electrical control assembly 12 is connected to the outer frame of the base frame 11 and located inside the base frame 11. The top beam 13 is installed on both sides of the top of the base frame 11. The crossbeam 14 is installed at the middle of the top of both sides of the base frame 11 and is located on top of the top beam 13. The top frame 15 is welded to the middle of the crossbeam 14. Rubber pads 16 are inserted into the bottom of both sides of the top frame 15. Anti-vibration pads are installed at the top and bottom connections of the top beam 13 to reduce vibrations generated during the movement of the gauge ruler 4. The rubber clamp 16 reduces the impact of the track gauge 4 being clamped within it. During movement, the track gauge 4 will collide with the top frame 15. The rubber clamp 16 is now placed between the top frame 15 and the track gauge 4 to prevent damage to the track gauge 4 from collisions. The electrical control component 12 contains multiple modules to control the automated operation of the entire detection device. The electrical control component 12 includes a PLC control module, a pneumatic control module, a position detection module, a detection counting module, and a power supply and signal transmission module. The PLC control module uses a PLC controller to control the output pressure of the multi-channel pneumatic control module to the push rod cylinders in the vertical lifting mechanism 2 and the horizontal lifting mechanism 3. The pneumatic control module uses a pneumatic solenoid valve for control. The detection counting module uses a position detection counter to record the number of times the action is completed. The frame of this invention is equipped with a horizontal lifting mechanism, a gauge ruler, and a detection component by a crossbeam installed at the top center of both sides of the bottom frame. The lifting mechanism is installed by a top frame connected to the middle of the crossbeam. Rubber pads are inserted at the bottom of both sides of the top frame to prevent collisions during the movement of the gauge ruler. Multiple modules inside the electronic control component control the automated operation of the entire detection device.

[0027] Specifically, such as Figure 2 , Figure 3 As shown, the gauge 4 includes a probe 41, a gauge body 42, a top balance block 43, and a side balance block 44. The gauge 4 serves as the object to be tested by the testing device. The probe 41 is located at the outermost ends of the gauge 4, and the gauge body 42 is located in the middle section of the gauge 4. Two balance blocks are installed on the gauge 4, which are composed of a top balance block 43 and a top balance block 44. The gauge body 42 also includes a gauge handle 51 and a gauge outer contour 52.

[0028] Specifically, such as Figure 4 , Figure 5As shown, the detection component 5 includes a gauge handle 51, a gauge outer contour 52, a display device 53, a front clamping device 54, an upper clamping device 55, a movable joint 56, and a movable wheel 57. The detection component 5 is designed to conform to the shape of the gauge handle 51 and the gauge outer contour 52. The front clamping device 54 is the main structure of the detection component 5. The bottom of the front clamping device 54 has a retaining ring structure and is bolted to the gauge 4. The upper clamping device 55 is installed on the top outer side of the front clamping device 54. The display device 53 is installed on the bottom side of the front clamping device 54. The movable joint 56 consists of two independently movable joint mechanisms, each bolted to the upper clamping device 54. On both sides of the top, the movable wheel 57 and the movable joint 56 are connected by a linkage, and the movable wheel 57 can rotate freely. Movable wheels 57 are provided in both joint mechanisms of the detection component 5. The detection component 5 can move accordingly with the movement of the gauge 4. During the entire movement of the gauge 4, one movable wheel 57 located inside the outer contour 52 of the gauge can rotate around the outer contour 52 of the gauge, thereby completing the service life detection of the gauge 4. The gauge handle 51 is connected to the vertical lifting mechanism 2 by a rubber rope to ensure that the vertical lifting mechanism 2 drives the gauge 4 to move. The display device 53 is equipped with a position detection counter. Every time the gauge 4 completes a movement, the display device 53 counts under the control of the detection counting module. The detection component of this invention uses a front clamping device with a clamping ring structure to lock the detection component onto the gauge and follow the movement of the gauge. Through two joint mechanisms formed by the movable joint and the movable wheel, it moves in close contact with the movement of the gauge and completes a circumferential rotation on the outer contour of the gauge, thereby completing the detection of the gauge life. The number of times the gauge completes the movement is recorded by a display device with an internal position detection counter, thus determining the gauge life.

[0029] like Figure 7 As shown, in another embodiment of the present invention, a method for using a detection device for detecting the service life of a track gauge is provided, comprising the following steps: Connect the power supply and pneumatic source of the detection device, check whether the signal transmission of the PLC control module inside the electrical control component 12 is normal, and confirm that the extension and retraction of the vertical lifting mechanism 2 and the horizontal lifting mechanism 3 are smooth and without jamming.

[0030] The gauge 4 to be tested is then smoothly clamped in the designated position of the testing device, ensuring that the track surface of the gauge 4 fits tightly against the contact area of ​​the testing device.

[0031] Through the operation interface of the electronic control component 12, the pressure output value of the pneumatic control module inside the electronic control component 12 is set according to the model of the track gauge 4, the actual working conditions on site, and the testing standard requirements, so that the action force of the vertical lifting mechanism 2 and the horizontal lifting mechanism 3 is consistent with the force state used on site.

[0032] After confirming the preset action logic program in the PLC control module inside the electrical control component 12, and after the parameters are set and verified to be correct, the electrical control component 12 issues a start command to start the automatic detection process of the service life of the track gauge 4.

[0033] After the detection device is started, the horizontal lifting mechanism 3 releases the gripper on the gauge 4, completing the preliminary action of horizontal release. The vertical lifting mechanism 2 extends and retracts upward, driving the gauge 4 to complete the lifting action, simulating the separation process of the gauge 4 and the rail in actual use.

[0034] Subsequently, the lateral lifting mechanism 3 operates again, pushing the gauge 4 to move horizontally on the contact surface, simulating the horizontal sliding wear of the gauge 4 after the gauge handle 51 is released on site.

[0035] Repeat the above action process to achieve continuous cyclical wear simulation. Combine the detection time to record the appearance of the gauge ruler 4 under different number of action cycles.

[0036] In summary, this testing device for track gauge service life detection uses PLC to precisely control pneumatic actuators, reproduces the actual complex wear scenario of track gauges, has standardized action sequence, accurate automatic counting, reliable test data, and is fully automated without manual intervention, greatly improving testing efficiency and accuracy.

[0037] Those skilled in the art will readily understand that the above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
