Description

Technical Field

[0001] The present invention relates to a rail transit, and particularly to a measuring ruler for a power rail of a maglev line. Background Art

[0002] When a maglev train stops or runs at a speed within 100 kilometers per hour, it needs external power supply, which is direct current. A contact shoe is used to conduct electricity between the power rail and the train. The current collector shoe of the train and the power rail need to be in close contact. During actual operation, when the contact gap between the power rail and the current collector shoe is too large, poor contact on the metal surface will cause arcing. Large-area arcing will result in burn pits, seriously affecting the service life of the power rail and posing a safety hazard to the power supply stability. Therefore, the installation position of the power rail must be strictly controlled within the range required by the design.

[0003] Conventional measurement methods mainly use a right-angle ruler for manual measurement. This method is difficult to accurately measure the position deviation of the power rail in both the X and Y directions simultaneously. Therefore, multiple measurements and calculation analyses are required, resulting in low work efficiency and poor measurement accuracy. Summary of the Invention

[0041] Magnetic levitation track functional member 200 Specific implementation manners

[0042] The descriptions of the following embodiments refer to the accompanying drawings to exemplify specific embodiments in which the present invention can be implemented.

[0043] As Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 and Figure 5 shown, this embodiment discloses a measuring ruler for a power rail of a maglev line. The measuring ruler for the power rail of the maglev line includes a measuring frame 1 and a plurality of 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 which is used for nesting and fitting against the magnetic levitation track functional member 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 horizontally extends in the direction close to the power rail 100, and the other end of the lower mounting member 11 has a measuring groove 111 which is used for nesting the power rail 100. The plurality of measuring components 2 are all connected to the lower mounting member 11, and the plurality of measuring components 2 all extend into the measuring groove 111 and are used for measuring the power rail 100. The positioning groove 121 has a positioning function. The measuring frame 1 is fitted against the magnetic levitation track functional member 200 through the positioning groove 121 to achieve precise positioning. The measuring components 2 have a measuring function. The position deviations of the power rail 100 in the X and Y directions are measured by the plurality of measuring components 2. If the values measured by the plurality of measuring components 2 are within the normal range, it indicates that the position of the power rail 100 meets the installation requirements; if the values measured by the plurality of measuring components 2 exceed the normal range, the position of the power rail 100 must be adjusted until the values of the plurality of measuring components 2 are all within the normal range to fully meet the requirements of the "Power Rail Maintenance Regulations".

[0044] When the maglev line power rail measuring ruler is in use, first, the positioning groove 121 is sleeved on the maglev track functional part 200, and the inner wall surface of the positioning groove 121 is in close contact with the outer surface of the maglev track functional part 200. Then, the power rail 100 is measured by multiple measuring components 2, which can quickly and accurately measure the position deviation of the power rail 100 in the X and Y directions, simplify the measurement process, improve the measurement efficiency, reduce the maintenance cost, ensure that the installation position of the power rail 100 meets the design requirements, and guarantee the safe and stable operation of the maglev train. Compared with the traditional right-angle ruler measurement method, the maglev line power rail measuring ruler in this embodiment improves the measurement accuracy while saving the maintenance cost and has broad application prospects. In the future, this technology can be popularized to other rail transit fields that require high-precision position measurement to provide an efficient solution for the maintenance of similar equipment.

[0045] The lower mounting part 11 includes an upper mounting portion 112, a side mounting portion 113, and a lower mounting portion 114. The side mounting portion 113 is located between the upper mounting portion 112 and the lower mounting portion 114, and the upper and lower ends of the side mounting portion 113 are respectively connected to the upper mounting portion 112 and the lower mounting portion 114, so that a measurement groove 111 is formed on the side facing the power rail 100 among the upper mounting portion 112, the side mounting portion 113, and the lower mounting portion 114. Multiple measuring components 2 are respectively mounted and connected to the upper mounting portion 112, the side mounting portion 113, and the lower mounting portion 114. The side mounting portion 113 is connected to the upper mounting portion 112 and the lower mounting portion 114 to form the measurement groove 111. The measurement groove 111 will be sleeved on the power rail 100, and the power rail 100 is measured by multiple measuring components 2 on the upper mounting portion 112, the side mounting portion 113, and the lower mounting portion 114, so as to quickly obtain the position deviation data of the power rail 100 and ensure the accuracy of the installation position of the power rail 100. At the same time, the overall structure of the lower mounting part 11 is simple.

[0046] In this embodiment, the number of power rails 100 is two, and the number of measuring components 2 is four. Two of the measuring components 2 are mounted and connected to the side mounting portion 113, and the other two measuring components 2 are respectively mounted and connected to the upper mounting portion 112 and the lower mounting portion 114, so that the two measuring components 2 located on the upper mounting portion 112 and above 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 below 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 through insulators. The four measuring components 2 are respectively used to measure the two power rails 100, and every two measuring components 2 are respectively used to measure two adjacent sides of the power rail 100, so as to measure the position deviation of the power rail 100 in the X and Y directions and ensure the accuracy of the installation position of the power rail 100.

[0048] The upper positioning member 12 includes an upper limiting portion 122, a side limiting portion 123, and a lower limiting portion 124. The upper limiting portion 122 and the lower limiting portion 124 are arranged at an interval in the vertical direction, and one ends of the upper limiting portion 122 and the lower limiting portion 124 are both connected to the side limiting portion 123. The other ends of the upper limiting portion 122 and the lower limiting portion 124 both extend horizontally in the direction close to the maglev track functional member 200, so as to form a positioning groove 121 between the upper limiting portion 122, the side limiting portion 123, and the lower limiting portion 124. The maglev track functional member 200 extends into the positioning groove 121, and the maglev track functional member 200 is in close contact with and abuts against the upper limiting portion 122, the side limiting portion 123, and the lower limiting portion 124. When in measurement use, the upper positioning member 12 moves horizontally in the direction close to the maglev track functional member 200, so that the upper limiting portion 122 closely slides on the top sliding surface of the maglev track functional member 200, the side limiting portion 123 closely abuts against the front guiding surface of the maglev track functional member 200, and at the same time, the lower limiting portion 124 abuts against the bottom of the maglev track functional member 200, thereby realizing the precise positioning of the maglev track functional member 200 in the upper positioning member 12 and ensuring the precise measurement of the maglev line power rail measuring ruler.

[0049] Wherein, the length of the upper limiting portion 122 is greater than the length of the lower limiting portion 124. When in measurement use, first, the top sliding surface of the maglev track functional member 200 is closely abutted against the upper limiting portion 122 and moves in the direction close to the side limiting portion 123, so that the maglev track functional member 200 is inserted into the positioning groove 121 and abuts against the side limiting portion 123 and the lower limiting portion 124.

[0050] In this embodiment, the bottom of the side limiting portion 123 extends downward beyond the lower limiting portion 124 and is connected to the upper mounting portion 112 and the lower mounting portion 114. An "F" shape is formed between the upper limiting portion 122, the side limiting portion 123, and the lower limiting portion 124, and a "C" shape is formed between the upper mounting portion 112, the side mounting portion 113, and the lower mounting portion 114. The upper mounting portion 112 and the lower mounting portion 114 are connected to the side limiting portion 123, making the overall structural stability of the measuring frame 1 higher. At the same time, the overall structure is simple and convenient for processing and manufacturing.

[0051] The upper mounting portion 112, the side mounting portion 113, the lower mounting portion 114, the upper limiting portion 122, the side limiting portion 123, and the lower limiting portion 124 are all profiles, that is, both the lower mounting member 11 and the upper positioning member 12 are profiles, with a simple structure and low cost. Among them, a lightweight aluminum alloy profile 30*30 can be used to make the measuring frame 1.

[0052] 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, a first reinforcing member 4 is provided. The first reinforcing member 4 has a reinforcing effect. The profiles are fixedly connected through the first reinforcing member 4, further strengthening the overall structural strength of the measuring frame 1 and achieving higher measuring accuracy of the maglev line power rail measuring ruler. Among them, the first reinforcing member 4 can be a right-angle fastener.

[0053] The maglev line power rail measuring ruler further includes a plurality of mounting seats 3. The plurality of mounting seats 3 are mounted and connected to the lower mounting member 11. The plurality of mounting seats 3 correspond to the plurality of measuring components 2 one by one. One end of the measuring component 2 is connected to the mounting seat 3, and the other end of the measuring component 2 passes through the mounting seat 3 and extends into the measuring groove 111. The mounting seat 3 is mounted and connected to the profile of the lower mounting member 11, and the measuring component 2 is mounted on the mounting seat 3, making the mounting stability of the measuring component 2 higher and achieving higher measuring accuracy of the maglev line power rail measuring ruler.

[0054] There is a second reinforcing member 5 between the mounting seat 3 and the lower mounting member 11. The second reinforcing member 5 has a reinforcing effect. The connection strength between the mounting seat 3 and the lower mounting member 11 is effectively strengthened through the second reinforcing member 5, further strengthening the overall structural strength of the maglev line power rail measuring ruler and achieving higher measuring accuracy of the maglev line power rail measuring ruler. Among them, the second reinforcing member 5 can be a right-angle fastener.

[0055] Among them, the mounting seat 3 can be an angle aluminum profile, and the measuring component 2 can be a dial indicator. Four angle aluminum profiles are fixed on the measuring frame 1 through M8 bolts, and four high-precision dial indicators are respectively mounted on the four angle aluminum profiles. After the dial indicator passes through the through hole on the angle aluminum profile, the dial indicator is fixed on the angle aluminum profile using an M4 bolt, making the overall structure more stable and reliable and further ensuring the measuring accuracy of the maglev line power rail measuring ruler.

[0056] When the maglev line power rail measuring ruler of this embodiment is in use, by observing the probe of the dial indicator, it is confirmed that the probe has contacted the surface of the power rail 100. The data of the power rail 100 in the X and Y directions are directly read through the dial indicator, and the values are recorded and compared with the original data for analysis. As long as the readings of all four dial indicators are within the normal range of -0.1 to +0.1, it indicates that the position of the power rail 100 meets the installation requirements. If the readings exceed the range of -0.3 to +0.3, the position of the power rail 100 must be adjusted until the readings are within the normal range, fully meeting the requirements of the "Power Rail Maintenance Regulations".

[0057] The magnetic levitation line power rail measuring ruler of this embodiment has been tested through multiple actual operations. The structure of the magnetic levitation line power rail measuring ruler is light, the data is clear, and it can complete measurements in two directions simultaneously, reducing the workload and improving work efficiency. By using a digital dial indicator, the measurement data is accurate, and the position deviation data of the power rail 100 can be quickly obtained to ensure the accuracy of the installation position of the power rail 100; moreover, the operation is simple, greatly shortening the measurement time and improving the maintenance efficiency; with the design of aluminum alloy material, the weight of the magnetic levitation line power rail measuring ruler is reduced, making it convenient to carry and use, and reducing the labor intensity of maintenance personnel; at the same time, it effectively solves the problem of having no suitable tool to use during the measurement and maintenance of the power rail of the magnetic levitation track beam, and provides a special tool.

[0058] The above-disclosed are only the preferred embodiments of the present invention. Of course, the scope of the rights of the present invention cannot be limited thereby. Therefore, equivalent changes made according to the claims of the present invention still fall within the scope covered by the present invention.
