Description

Technical Field

[0001] This invention relates to the field of construction technology, specifically to a device and method for rapid and precise installation of U-shaped anchor bolts for steel rails. Background Technology

[0002] In the construction industry, individual anchor plates used for heavy-duty rails are prone to displacement after prolonged use, making rail maintenance difficult and, in severe cases, even causing vehicle derailment. To improve the process, the anchor bolt plates for opposite rails are designed as a single unit, while two individual anchor bolts are designed as a single U-shaped anchor bolt. Because the anchor plates are a single unit, the installation precision requirements for the anchor bolts are relatively high; the U-shaped anchor bolts, being a single unit, are even more difficult to control in terms of installation precision.

[0003] The traditional installation method for U-shaped anchor bolts involves checking the spacing of the bolts before installation and ensuring the dimensions are within the design tolerance range. A steel wire is then hung along the longitudinal centerline of the track. During installation, the center position is adjusted by measuring the deviation value using a tape measure based on the wire wire's position, and the elevation is controlled using a level. After adjustment, the U-shaped anchor bolts are welded and fixed to the concrete structure's surface reinforcement using reinforcing bars. This method involves numerous steps, including pre-calibration of the U-shaped anchor bolts, and the measurement of center position deviation using a tape measure is highly variable and difficult to control accurately. The entire process requires leveling and significant manual labor. Traditional methods struggle to guarantee installation accuracy, incur higher costs for subsequent bolt processing, and require a large number of personnel. Therefore, there is an urgent need to invent a device and method for installing U-shaped anchor bolts to improve installation efficiency and accuracy. Summary of the Invention

[0004] (a) Technical problems to be solved

[0005] To address the shortcomings of existing technologies, this invention provides a rapid and precise installation device and method for U-shaped anchor bolts used in rails. The device allows for direct adjustment of the U-shaped bolt spacing using its upper leveling limit plate. Furthermore, the installation of U-shaped anchor bolts requires only one worker, thus solving the problems mentioned in the background section.

[0008] Preferably, the clamping part includes a lower clamping plate, an upper clamping plate, and a first fastening bolt. The lower clamping plate is movably connected to the bottom of the upper clamping plate, and the two are locked and fixed together by the first fastening bolt.

[0011] Preferably, the rotating connecting rod is used to adjust the center position of the entire device, and the elevation of the U-shaped anchor bolts is adjusted by raising and lowering the sleeve and rotating rod. The leveling nut is used to adjust the height difference between the two sides of the U-shaped anchor bolts, and the bubble level can be used to observe whether the entire device remains level.

[0012] Preferably, the operating steps of the device are as follows:

[0013] S1. Based on the specifications and dimensions of the U-shaped anchor bolts, manufacture a set of upper leveling and limiting structures;

[0014] S2. Based on the elevation of the U-shaped anchor bolts and the height of the concrete surface reinforcement, manufacture the rotatable and adjustable part of the device;

[0015] S3. Make the clamping part of the device according to the spacing of the U-shaped anchor bolts;

[0016] S4. Hang a 0.5mm steel wire at the longitudinal centerline of the track. The steel wires should be at the same elevation and the elevation value should be recorded.

[0017] S5. Secure the device at the installation position of the U-shaped anchor bolt using the upper and lower clamps;

[0018] S7. Adjust the angle of the connecting rod so that the steel ruler on the top of the device is close to the steel wire, thus adjusting the center position of the U-shaped anchor bolt;

[0019] S8. Adjust the two leveling nuts on the left and right, observe the position of the level bubble meter, and determine whether the entire device is level. At the same time, ensure that the tops of the two screws are at the same elevation.

[0020] S9. By adjusting the sleeve, control the up and down movement of the U-shaped anchor bolts, observe the reading of the steel ruler, and ensure that the elevation of the U-shaped anchor bolts meets the design requirements.

[0021] S10. Finally, check the longitudinal centerline, transverse centerline, bolt spacing, and top elevation of the U-shaped anchor bolts. Once all requirements are met, the U-shaped anchor bolts can be welded and fixed to the concrete surface steel bars using scrap steel bars.

[0022] S11. Remove the device and install the next set of U-shaped anchor bolts using the same method.
