Description

Technical Field

[0001] This utility model relates to rail transit, and more particularly to a measuring ruler for a maglev power rail. Background Technology

[0002] Maglev trains require external power supply, specifically direct current (DC), when stationary or operating at speeds below 100 km / h. Contact shoes connect the power rail and the train, ensuring tight contact between the train's current-collecting shoes and the power rail. During actual operation, excessive gaps between the power rail and the current-collecting shoes can lead to poor metal-to-metal contact and arcing. Large-area arcing can cause burn marks and pitting, severely impacting the lifespan of the power rail and posing a safety hazard to power supply stability. Therefore, the installation location of the power rail must be strictly controlled within the design requirements.

[0003] Conventional measurement methods mainly involve manual measurement using a right-angle ruler. This method is difficult to accurately measure the positional deviation of the dynamic rail in both the X and Y directions simultaneously. Therefore, multiple measurements and calculations are required, resulting in low work efficiency and poor measurement accuracy. Utility Model Content

[0041] Magnetic levitation track functional components 200 Detailed Implementation

[0042] The following description of the embodiments is with reference to the accompanying drawings, which illustrate specific embodiments in which the present invention can be implemented.

[0043] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, this embodiment discloses a maglev line dynamic track measuring ruler, which includes a measuring frame 1 and multiple measuring components 2. The measuring frame 1 includes a lower mounting member 11 and an upper positioning member 12. The upper positioning member 12 has a positioning groove 121 for nesting and fitting against the maglev track functional component 200. One end of the lower mounting member 11 is connected to the bottom of the upper positioning member 12, and the other end of the lower mounting member 11 extends horizontally in the direction close to the dynamic track 100. The other end of the lower mounting member 11 has a measuring groove 111 for nesting the dynamic track 100. Multiple measuring components 2 are all connected to the lower mounting member 11, and all multiple measuring components 2 extend into the measuring groove 111 and are used to measure the dynamic track 100. The positioning groove 121 has a positioning function, and the measuring frame 1 fits against the maglev track functional component 200 through the positioning groove 121 to achieve precise positioning. The measuring component 2 has a measuring function. Multiple measuring components 2 are used to measure the positional deviation of the power rail 100 in the X and Y directions. If the values ​​measured by multiple measuring components 2 are within the normal range, it means that the position of the power rail 100 meets the installation requirements. If the values ​​measured by multiple measuring components 2 exceed the normal range, the position of the power rail 100 must be adjusted until the values ​​of multiple measuring components 2 are all within the normal range to fully meet the requirements of the "Power Rail Maintenance Procedure".

[0044] When using the maglev line dynamic rail measuring ruler, the positioning groove 121 is first fitted onto the maglev track functional component 200, with the inner wall of the positioning groove 121 abutting against the outer surface of the maglev track functional component 200. Then, multiple measuring components 2 are used to measure the dynamic rail 100, enabling rapid and accurate measurement of the positional deviation of the dynamic rail 100 in both the X and Y directions. This simplifies the measurement process, improves measurement efficiency, reduces maintenance costs, ensures that the installation position of the dynamic rail 100 meets design requirements, and guarantees the safe and stable operation of the maglev train. Compared to traditional right-angle ruler measurement methods, the maglev line dynamic rail measuring ruler of this embodiment improves measurement accuracy while saving maintenance costs, and has broad application prospects. In the future, this technology can be extended to other rail transit fields requiring high-precision position measurement, providing an efficient solution for the maintenance of similar equipment.

[0045] The lower mounting part 11 includes an upper mounting part 112, a side mounting part 113, and a lower mounting part 114. The side mounting part 113 is located between the upper mounting part 112 and the lower mounting part 114, and the upper and lower ends of the side mounting part 113 are respectively connected to the upper mounting part 112 and the lower mounting part 114, so that a measuring groove 111 is formed between the upper mounting part 112, the side mounting part 113, and the lower mounting part 114 on the side facing the power rail 100. A plurality of measuring components 2 are respectively mounted and connected to the upper mounting part 112, the side mounting part 113, and the lower mounting part 114. The side mounting part 113 is connected to the upper mounting part 112 and the lower mounting part 114 and forms a measuring groove 111. The measuring groove 111 will be fitted onto the power rail 100, and the power rail 100 will be measured by multiple measuring components 2 on the upper mounting part 112, the side mounting part 113 and the lower mounting part 114, thereby quickly obtaining the position deviation data of the power rail 100 and ensuring the accuracy of the installation position of the power rail 100; at the same time, the lower mounting part 11 has a simple overall structure.

[0046] In this embodiment, there are two power rails 100 and four measuring components 2. Two measuring components 2 are mounted on the side mounting portion 113, and the other two measuring components 2 are mounted on the upper mounting portion 112 and the lower mounting portion 114, respectively. This is so that the two measuring components 2 located on the upper mounting portion 112 and the side mounting portion 113 are used to measure one of the power rails 100, and the two measuring components 2 located on the lower mounting portion 114 and the side mounting portion 113 are used to measure the other power rail 100.

[0047] Specifically, the two power rails 100 are respectively connected and installed on the power rail adjustment bracket via insulators. Four measuring components 2 are used to measure the two power rails 100 respectively, and each pair of measuring components 2 is used to measure two adjacent sides of the power rail 100, thereby measuring the positional deviation of the power rail 100 in the X and Y directions, ensuring the accuracy of the installation position of the power rail 100.

[0048] The upper positioning member 12 includes an upper limit part 122, a side limit part 123, and a lower limit part 124. The upper limit part 122 and the lower limit part 124 are spaced vertically apart, and one end of the upper limit part 122 and the lower limit part 124 are connected to the side limit part 123. The other end of the upper limit part 122 and the lower limit part 124 extend horizontally in the direction close to the maglev track functional member 200, so that a positioning groove 121 is formed between the upper limit part 122, the side limit part 123, and the lower limit part 124. The maglev track functional member 200 extends into the positioning groove 121 and abuts against the upper limit part 122, the side limit part 123, and the lower limit part 124. During measurement, the upper positioning member 12 moves horizontally along the direction close to the maglev track functional member 200, so that the upper limit part 122 is in close contact with the top sliding surface of the maglev track functional member 200, the side limit part 123 is in close contact with the front guide surface of the maglev track functional member 200, and the lower limit part 124 is in contact with the bottom of the maglev track functional member 200, thereby achieving precise positioning of the maglev track functional member 200 within the upper positioning member 12, ensuring accurate measurement by the maglev line dynamic track measuring ruler.

[0049] The upper limit part 122 is longer than the lower limit part 124. When measuring, the top sliding surface of the magnetic levitation track functional component 200 is first placed against the upper limit part 122 and moved towards the side limit part 123, so that the magnetic levitation track functional component 200 is inserted into the positioning groove 121 and abuts against the side limit part 123 and the lower limit part 124.

[0050] In this embodiment, a lower limiting part 124 extends downward from the bottom of the side limiting part 123 and connects to the upper mounting part 112 and the lower mounting part 114. An "F" shape is formed between the upper limiting part 122, the side limiting part 123, and the lower limiting part 124, while an "I" shape is formed between the upper mounting part 112, the side mounting part 113, and the lower mounting part 114. The upper mounting part 112 and the lower mounting part 114 are connected to the side limiting part 123, resulting in higher overall structural stability of the measuring frame 1. Simultaneously, the overall structure is simple and easy to manufacture.

[0051] The upper mounting part 112, side mounting part 113, lower mounting part 114, upper limit part 122, side limit part 123, and lower limit part 124 are all profiles, meaning that both the lower mounting part 11 and the upper positioning part 12 are profiles, resulting in a simple structure and low cost. The measuring frame 1 can be made of lightweight 30*30 aluminum alloy profile.

[0052] First reinforcing members 4 are provided between the side limiting part 123 and the upper limiting part 122, between the side limiting part 123 and the lower limiting part 124, between the side limiting part 123 and the upper mounting part 112, between the side limiting part 123 and the lower mounting part 114, between the side mounting part 113 and the upper mounting part 112, and between the side mounting part 113 and the lower mounting part 114. The first reinforcing members 4 provide reinforcement, and the profiles are fixedly connected through the first reinforcing members 4, further strengthening the overall structural strength of the measuring frame 1 and achieving higher measurement accuracy for the maglev line dynamic rail measuring ruler. The first reinforcing member 4 can be a right-angle fastener.

[0053] The maglev line dynamic track measuring ruler also includes multiple mounting bases 3, which are installed and connected to the lower mounting component 11. Each mounting base 3 corresponds one-to-one with a multiple measuring component 2. One end of the measuring component 2 is connected to the mounting base 3, and the other end of the measuring component 2 passes through the mounting base 3 and extends into the measuring groove 111. The mounting bases 3 are installed and connected to the profile of the lower mounting component 11, and the measuring components 2 are mounted on the mounting bases 3, resulting in higher installation stability for the measuring components 2 and higher measurement accuracy for the maglev line dynamic track measuring ruler.

[0054] A second reinforcing member 5 is provided between the mounting base 3 and the lower mounting component 11. The second reinforcing member 5 strengthens the connection between the mounting base 3 and the lower mounting component 11, further enhancing the overall structural strength of the maglev line dynamic rail measuring ruler and achieving higher measurement accuracy. The second reinforcing member 5 can be a right-angle fastener.

[0055] The mounting base 3 can be an angle aluminum profile, the measuring component 2 can be a dial indicator, and the measuring frame 1 is fixed with four angle aluminum profiles by M8 bolts. Four high-precision dial indicators are installed on the four angle aluminum profiles respectively. After the dial indicator passes through the through hole on the angle aluminum profile, the dial indicator is fixed to the angle aluminum profile with M4 bolts, making the overall structure more stable and reliable, and further ensuring the measurement accuracy of the maglev line dynamic rail measuring ruler.

[0056] In this embodiment, the maglev line dynamic rail measuring ruler is used by observing the dial indicator probe to confirm that the probe is in contact with the surface of the dynamic rail 100. The dial indicator directly reads the data of the dynamic rail 100 in both the X and Y directions, records the values, and compares them with the original data. If all four dial indicator readings are within the normal range of -0.1 to +0.1, the position of the dynamic rail 100 meets the installation requirements. If the readings exceed the range of -0.3 to +0.3, the position of the dynamic rail 100 must be adjusted until the readings are within the normal range, fully meeting the requirements of the "Dynamic Rail Maintenance Procedure".

[0057] The maglev line dynamic rail measuring ruler of this embodiment has undergone multiple practical tests. Its lightweight structure and clear data allow for simultaneous measurements in two directions, reducing workload and improving efficiency. Employing a digital dial indicator ensures accurate measurement data and quickly obtains positional deviation data for the dynamic rail 100, guaranteeing the accuracy of its installation position. Its ease of operation significantly shortens measurement time and improves maintenance efficiency. The aluminum alloy design reduces the weight of the measuring ruler, making it easy to carry and use, thus reducing the workload of maintenance personnel. Furthermore, it effectively solves the problem of lacking suitable tools during the measurement and maintenance of the maglev track beam dynamic rail, providing a dedicated tool.

[0058] The above-disclosed embodiments are merely preferred embodiments of the present utility model and should not be construed as limiting the scope of the present utility model. Therefore, any equivalent variations made in accordance with the claims of the present utility model shall still fall within the scope of the present utility model.
