[0002] As a crucial component of the railway transportation system, turnouts ensure the safe and efficient switching of trains between different tracks. Consequently, turnout precision requirements are extremely stringent. During turnout installation and maintenance, multiple key parameters must be measured, including the horizontality and verticality of the turnout lock frame, the verticality of the tie rods between the two lock frames, and the horizontality of the rails.

[0003] Currently, the industry generally lacks specialized measurement tools for these critical parameters. Currently, most railway maintenance personnel rely on traditional methods such as simple rulers. This method is not only cumbersome, but also prone to increased measurement errors due to the limited accuracy of the measuring tools, failing to meet high-precision requirements. Furthermore, due to the design limitations of existing tools, the measurement process is often time-consuming, impacting turnout maintenance efficiency.

[0004] Therefore, it is necessary to further improve and perfect the existing technology to overcome these shortcomings, and the present invention is made based on this situation. Utility Model Content

[0026] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention is further described in detail below with reference to the accompanying drawings and specific implementation methods.

[0027] like Figures 1 to 3 As shown, the present invention provides a turnout calibration device, which primarily comprises a main rod 1 positioned transversely between two rails, with a rotating block 2 rotatably connected to one end of the main rod 1. The rotating connection structure is specifically designed as follows: a rotating shaft 21 is provided on the inner side of the rotating block 2, while a corresponding position on the end surface of the main rod 1 is provided with an axial hole 12 that engages with the rotating shaft 21. This design enables the rotating block 2 to flexibly rotate around the main rod 1.

[0028] Furthermore, the rotating block 2 is provided with a first auxiliary rod 3, which is perpendicular to the main rod 1. A telescopic rod 4 is slidably connected to the other end of the main rod 1 along its length. The telescopic rod 4 is provided with a second auxiliary rod 5, which is perpendicular to the main rod 1. To enhance the stability and practicality of the device, the main rod 1, the first auxiliary rod 3, and the second auxiliary rod 5 are preferably square rods. This not only facilitates installation and adjustment but also ensures stability during calibration. Naturally, the bottom surfaces of the first and second auxiliary rods 3 and 5 protrude downward from the bottom surface of the main rod 1.

[0029] During use, the main rod 1 is placed horizontally between the two rails, with the bottom surface of the first auxiliary rod 3 tightly fitting the top surface of the lock frame on one side of the turnout, while ensuring that the two adjacent side surfaces of the first auxiliary rod 3 are aligned with the two side surfaces of the corresponding lock frame. Similarly, the bottom surface of the second auxiliary rod 5 tightly fits the top surface of the lock frame on the other side of the turnout, while ensuring that the two adjacent side surfaces of the second auxiliary rod 5 are aligned with the two side surfaces of the corresponding lock frame. This structural design effectively calibrates the verticality of the lock frames on both sides of the turnout, ensuring that the turnout maintains proper function after installation.

[0030] In addition, the second auxiliary rod 5 can be extended and retracted along with the telescopic rod 4 to adapt to rails of different widths. This design makes the switch calibration device widely applicable, enabling accurate calibration under different rail widths, improving the installation quality and operational safety of the switch.

[0031] Furthermore, a level 6 is installed on the main rod 1, the first auxiliary rod 3 and the second auxiliary rod 5. This design improves the functionality of the device, making it not only able to calibrate the verticality of the lock frame, but also to accurately measure and adjust the horizontality of the rail and the lock frame.

[0032] Specifically, the spirit level 6 on the main pole 1 is located on its top surface, allowing the operator to quickly and easily measure the level between the two rails. By reading the scale or digital display on the spirit level 6, the operator can intuitively understand the horizontal state of the rails and make corresponding adjustments accordingly to ensure the consistency of the rails in the horizontal direction. The spirit levels 6 installed on the first auxiliary pole 3 and the second auxiliary pole 5 are used to measure and calibrate the level of the locking frames on both sides of the turnout, respectively. Since the level of the locking frames is also crucial for the precise switching of the turnout, the provision of these two spirit levels 6 enables the operator to independently monitor and adjust the horizontal state of the locking frames on both sides, thereby ensuring the coordination between the locking frames and the rails, and avoiding turnout failures or safety hazards caused by level deviations.

[0033] The level 6 can be a traditional liquid level or a modern electronic level. The latter usually has digital display and sound prompt functions, making the reading more accurate and the operation easier.

[0034] Furthermore, a slider 51 is slidably connected to the telescopic rod 4, and the second auxiliary rod 5 is fixed on the slider 51, thereby providing greater flexibility and adaptability and enabling quick fine-tuning.

[0035] To further improve calibration accuracy and ease of operation, the present invention also features a stopper mechanism comprising a first stopper 8 slidably connected to the first secondary rod 3 and a second stopper 9 slidably connected to the second secondary rod 5. Both the first stopper 8 and the second stopper 9 facilitate accurate alignment of the corresponding secondary rods and the lock frame. The details are as follows:

[0036] The primary function of the first stopper 8 is to ensure that the two adjacent side surfaces of the first secondary rod 3 are precisely aligned with the corresponding side surfaces of the lock frame. To achieve this, the first stopper 8 is designed with two side ribs: a first side rib 81 and a second side rib 82. When the first side rib 81 slides downward, it extends downward from the bottom surface of the first secondary rod 3 from one side, while when the second side rib 82 slides downward, it extends downward from the bottom surface of the first secondary rod 3 from the other adjacent side. These two side ribs are movable up and down. When raised, their bottom surfaces are flush with the bottom surface of the first secondary rod 3. When lowered, they protrude downward from the bottom surface of the first secondary rod 3. When the first stopper 8 is raised, it allows for level measurement and calibration, avoiding interference. When the first stopper 8 is lowered, it facilitates contact and alignment between the two side ribs (first side 81 and second side 82) and the side surfaces of the lock frame, ensuring that the two adjacent side surfaces of the first secondary rod 3 are precisely aligned with the two side surfaces of the corresponding lock frame.

[0037] To secure the first stopper 8 and limit its unnecessary lifting and lowering motion, a first locking bolt 83 is provided between the first stopper 8 and the first auxiliary rod 3. The first locking bolt 83 is threadedly connected to the first stopper 8 and pivotally connected to the first auxiliary rod 3. Once the first stopper 8 is adjusted to the proper position, the operator can tighten the first locking bolt 83 to lock the first stopper 8, ensuring its stability during the calibration process.

[0038] Similarly, the second secondary rod 5 is also provided with a slidingly connected second stopper 9, which is similar in design to the first stopper 8 and includes a third rib 91 and a fourth rib 92. The third rib 91 and the fourth rib 92 can move up and down. When the second stopper 9 is raised, the bottom surfaces of the two ribs are flush with the bottom surface of the second secondary rod 5 to avoid interference with the second stopper 9. When the second stopper 9 is lowered, the two ribs protrude downward from the bottom surface of the second secondary rod 5 to contact and align with the side of the lock frame.

[0039] Similarly, to maintain the stability of the second stopper 9 during the calibration process, a second locking bolt 93 is provided between the second stopper 9 and the second secondary rod 5. The second locking bolt 93 is also threadedly connected to the second stopper 9 and rotatably connected to the second secondary rod 5. Once the second stopper 9 is adjusted to the appropriate position, the operator can tighten the second locking bolt 93 to lock the second stopper 9, ensuring that it does not move during the entire calibration process.

[0040] In order to enhance the functionality and practicality of the turnout calibration device, the present invention has designed a lighting indicator system. The system includes a slit 7 provided at the center of the bottom surface of the main pole 1 or telescopic pole 4, and extending along the length of the main pole 1 or telescopic pole 4.

[0041] A light bar 71 is located within the slit 7. Light from the light bar 71 projects through the slit, forming a straight, narrow line of light. When the main pole 1 is placed horizontally between the rails, the light from the light bar 71, through the slit 7, shines directly onto the tie rod, providing an intuitive visual reference for the operator to determine whether the tie rod is straight and needs adjustment.

[0042] In addition, to facilitate the control of the working state of the light bar 71, the light bar 71 is connected to a power supply and a control panel 72. The power supply provides the necessary power to the light bar 71, and the control panel 72 provides a user interface, allowing the operator to turn the light bar 71 on or off as needed, as well as adjust the brightness and direction of the light.

[0043] In addition, the above-mentioned slit 7 and light bar 71 can be replaced by laser.

[0044] Through the design of this lighting indication system, the turnout calibration device of this utility model not only provides precise mechanical calibration, but also provides a more intuitive and convenient calibration experience through the assistance of light. This innovative design not only improves the efficiency and accuracy of calibration, but also reduces the labor intensity of the operator.

[0045] Furthermore, a handle 11 is provided on the top of the main pole 1, so that an operator can easily hold and lift the main pole 1, thereby facilitating the movement and transportation of the device.

[0046] In summary, the present invention not only simplifies the operation process and reduces the difficulty of operation, but also significantly improves the calibration accuracy and reduces errors by integrating the verticality calibration, horizontality calibration and pull rod calibration functions of the lock frame and the rail.
