Description
Technical Field
[0001] The utility model relates to the field of point rail detection, in particular to a point rail detection platform. Background Art
[0002] The point rail is an important component in the switch. The train is guided to the main line or the siding line by turning the point rail, thereby realizing the track change of the train. Therefore, during the continuous movement and use of the point rail, the side where the top of the point rail contacts the base rail is easily worn, which makes the contact gap between the top of the point rail and the base rail larger, thereby affecting the stability and comfort of the train's travel, and even causing the wheels of the train to climb onto the point rail and cause a travel accident. Therefore, it is necessary to regularly detect the wear on the side of the point rail for timely inspection and replacement. However, the existing detection methods are generally complicated, the detection equipment is expensive and can only detect the positions with greater wear, and cannot reflect the wear of other positions with less wear. It is impossible to conduct a comprehensive analysis of the wear of the entire point rail, which increases the difficulty of targeted maintenance or replacement at a later stage.

[0006] Furthermore, the pressure sensing component is a contact pressure sensor, and the contact pressure sensor is in contact with one end of the compression spring.
[0007] Furthermore, a fixed sleeve is provided on the detection seat, the support rod is slidably connected inside the fixed sleeve, and the compression spring is arranged between the support rod and the end of the fixed sleeve.
[0008] Furthermore, a support is provided at the end of the support rod, the detection wheel is rotatably connected to the support, and the compression spring is arranged between the support and the end of the fixed sleeve.
[0009] Furthermore, the clamping plate is slidably connected in the fixing groove in the transverse direction, a plurality of adjusting columns are threadedly connected on the side wall of the fixing groove, and the ends of the adjusting columns are rotatably connected to the side surface of the clamping plate.
[0010] Furthermore, a slide groove is provided on the support plate, and a slider is provided on the detection seat. The slider is slidably connected in the slide groove, and the clamping column is threadedly connected to the top of the fixing groove. The end of the clamping column passes through the side wall of the fixing groove and contacts the top of the point rail.
[0011] Compared with the prior art, the beneficial effects of the present invention are:
[0012] 1. The structure of the utility model places the point rail in the fixed groove of the main body of the test bench during use, and clamps and clamps the side and top of the point rail to ensure that the point rail remains stable during testing. The sliding movement of the test seat on the side support plate of the fixed groove is used to drive the test seat to slide along the length direction of the point rail for testing, thereby achieving a comprehensive test of the wear conditions at different positions on the entire point rail. The test results are more comprehensive and accurate, and the wear condition of the point rail is monitored in real time, reducing the difficulty of subsequent maintenance or replacement.

Such a structure enables the detection wheel at the end of the support rod to maintain a rolling contact state with the side surface of the top of the pointed rail under the action of the compression spring. When the detection wheel passes through the wear position, the support rod slides relative to the detection seat under the action of the compression spring, thereby changing the compression length of the compression spring, causing the elastic force of the compression spring to change. The change in elastic force is displayed through the pressure change felt by the pressure sensing component, thereby indirectly performing a comprehensive analysis and display of the wear condition of the top side of the pointed rail, facilitating accurate control of the overall wear condition of the pointed rail, and ensuring the comprehensiveness and convenience of the detection.

It should be understood that these embodiments are only used to illustrate the present invention and are not used to limit the scope of the present invention. In addition, it should be understood that after reading the content taught by the present invention, those skilled in the art can make various changes or modifications to the present invention, and these equivalent forms also fall within the scope defined by the present application.
[0021] Reference Figure 1 and Figure 2The utility model is a detection platform for a pointed rail, the main structure of which includes a detection platform body 1, the detection platform body 1 is used as a supporting component, and a plurality of legs are welded or bolted at the bottom. The top of the detection platform body 1 is provided with a fixing groove 3 for matching with the pointed rail 2, and the fixing groove 3 is used to place the pointed rail 2. The side and top of the fixing groove 3 are respectively provided with a clamping plate 4 and a clamping column 5 for matching with the pointed rail 2. After the pointed rail 2 is placed in the fixing groove 3, the clamping plate 4 and the clamping column 5 are used to press and fix the pointed rail 2 to the bottom and side of the fixing groove 3, so as to achieve stability during the detection of the pointed rail 2. To ensure the accuracy of detection, a support plate 6 is welded or integrally formed on one side of the fixing groove 3, and a detection seat 7 is slidably connected to the support plate 6 along the length direction of the pointed rail 2. The detection seat 7 slides along the support plate 6 under the drive of any existing power structure. Specifically, a screw rod can be rotatably set on the support plate 6, and the screw rod penetrates the detection seat 7 and is threadedly connected thereto. The screw rod is driven by a motor to rotate so that the detection seat 7 slides along the support plate 6, thereby realizing accurate driving of the detection seat 7 to slide. A support rod 8 is slidably connected to the detection seat 7, and the sliding direction of the support rod 8 is consistent with the detection seat 7. The sliding direction of the measuring seat 7 is vertical. A compression spring 9 is provided between the measuring seat 7 and the support rod 8. Under the elastic force of the compression spring 9, the support rod 8 maintains a tendency to move toward the pointed rail 2. One end of the support rod 8 is rotatably connected to a detection wheel 10 through a bearing. The detection wheel 10 is in rolling contact with the side surface of the top of the pointed rail 2. Such a structure enables the measuring seat 7 to slide along the support plate 6, and the detection wheel 10 to roll along the side surface of the top of the pointed rail 2. When the detection wheel 10 passes the wear position on the side surface of the top of the pointed rail 2, the support rod 8 will slide relative to the measuring seat 7 under the action of the compression spring 9, so that The detection wheel 10 always maintains rolling contact with the point rail 2, so that the compression length of the compression spring 9 will change, thereby changing the elastic force of the compression spring 9. The detection seat 7 is provided with a pressure sensing component used in conjunction with the compression spring 9. The pressure sensing component can sense and display the real-time pressure of the compression spring 9, thereby indirectly displaying the wear condition of the side of the point rail 2, thereby achieving a comprehensive analysis and display of the wear condition of the side of the entire point rail 2. It has a simple structure and is easy to operate, which greatly improves the comprehensiveness and accuracy of wear detection and improves the convenience of subsequent inspection and replacement of the point rail 2.
[0022] Preferably, the pressure sensing component is a contact pressure sensor 11, and the contact pressure sensor 11 is in contact with one end of the compression spring 9. Specifically, a pressure sensor of model FCCN produced by Shenzhen Fusentech Sensing Technology Co., Ltd. can be used. It can receive pressure changes of the compression spring 9 and output current signals by contacting the compression spring 9. It has a simple structure, low cost, and more accurate and convenient feedback on the wear of the point rail 2.
[0023] Preferably, refer to Figure 3 and Figure 4A fixed sleeve 12 is welded or bolted on the detection seat 7, and the support rod 8 is slidably connected to the inside of the fixed sleeve 12, so that the sliding movement of the support rod 8 relative to the detection seat 7 is more stable and accurate. The compression spring 9 is arranged between the support rod 8 and the end of the fixed sleeve 12. Such a structure makes the setting position of the compression spring 9 more secure, and makes the sensing of the pressure sensing component more accurate when the telescopic length changes.
[0024] Preferably, a support 13 is welded or bolted to the end of the support rod 8. Specifically, the support 13 is U-shaped. The detection wheel 10 is rotatably connected to the U-shaped support 13 through a bearing. The compression spring 9 is arranged between the support 13 and the end of the fixed sleeve 12. Such a structure enables the two ends of the compression spring 9 to contact the support 13 and the end of the fixed sleeve 12 respectively, making its setting position more secure. At the same time, the U-shaped support 13 makes it difficult for the detection wheel 10 to tilt, thereby further improving the accuracy of the wear detection on the top side of the point rail 2.
[0025] Preferably, the clamping plate 4 is connected in a transverse sliding manner in the fixing groove 3, and a plurality of adjusting columns 14 are threadedly connected on the side walls of the fixing groove 3. The ends of the adjusting columns 14 are rotatably connected to the side surfaces of the clamping plate 4 via bearings. Such a structure can drive the clamping plate 4 at its end to slide in the fixing groove 3 under the action of the threaded connection by rotating a plurality of adjusting columns 14 and maintain the clamping state after adjustment. The structure is simple, the operation is convenient, and the clamping and fixing effect on the side surfaces of the point rail 2 is better.
[0026] Preferably, a slide groove 15 is provided on the support plate 6, and the slide groove 15 is formed by a downward depression on the top of the support plate 6. A slider 16 is welded or bolted on the detection seat 7, and the slider 16 is slidably connected in the slide groove 15. Preferably, the longitudinal section of the detection seat 7 is also U-shaped, which is sleeved on the top of the support plate 6. At the same time, the slider 16 penetrates into the slide groove 15 and is slidably connected thereto, so that the sliding movement of the detection seat 7 relative to the support plate 6 is more stable and smooth. The clamping column 5 is threadedly connected to the top of the fixing groove 3, and the end of the clamping column 5 passes through the side wall of the fixing groove 3 and contacts with the top of the point rail 2. Such a structure only requires a simple rotation of the clamping column 5 to rotate and move the end of the clamping column 5 until it contacts the top of the point rail 2 to achieve clamping and fixing it, which makes the fixing operation of the point rail 2 more convenient and efficient.
[0027] Working principle: When in use, the structure of the utility model places the point rail 2 in the fixing groove 3 of the test platform body 1, and uses the clamping plate 4 and the clamping column 5 to clamp and fix its sides and top, so that the point rail 2 maintains stability during detection, and uses the sliding movement of the detection seat 7 on the side support plate 6 of the fixing groove 3 to drive the detection seat 7 to slide along the length direction of the point rail 2 for detection, thereby realizing a comprehensive detection of the wear conditions of different positions on the entire point rail 2, and the detection result is more comprehensive and accurate, realizing real-time monitoring of the wear condition of the point rail 2, and reducing the difficulty of subsequent maintenance or replacement; a support rod 8 is slidably connected to the detection seat 7, and a compression spring 9 is provided between the support rod 8 and the detection seat 7. The end portion is rotatably connected to a detection wheel 10 which is in rolling contact with the side surface of the top of the point rail 2. Such a structure enables the detection wheel 10 at the end of the support rod 8 to maintain a rolling contact state with the top side surface of the point rail 2 under the action of the compression spring 9. When the detection wheel 10 passes the wear position, the support rod 8 slides relative to the detection seat 7 under the action of the compression spring 9, thereby causing the compression length of the compression spring 9 to change, resulting in a change in the elastic force of the compression spring 9. The change in elastic force is displayed through the pressure change felt by the pressure sensing component, thereby indirectly analyzing and displaying the wear condition of the top side surface of the point rail 2, facilitating accurate control of the overall wear condition of the point rail 2, and ensuring the comprehensiveness and convenience of the detection.
