Especially in the ever-changing field environment, manual measurement can severely impact work efficiency and construction quality, hindering project progress.

[0036] As shown in the figure, the embodiment of the present invention provides a track positioning tool, including: a base and a prism 3,

[0037] The base includes a base body 1 and an extension portion 2 connected to each other. The bottom surface of the base body 1 is a first contact surface 11, and the side of the extension portion 2 facing the first contact surface 11 is a second contact surface 21. The first contact surface 11 and the second contact surface 21 are perpendicular to each other.

[0038] The top surface of the base body 1 has a first mounting position 4 and a second mounting position 5, and the prism 3 is detachably connected to the base body 1 at the first mounting position 4 and the second mounting position 5;

[0039] The center line of the first mounting position 4 coincides with the second contact surface 21; the vertical distance between the center line of the second mounting position 5 and the second contact surface 21 is equal to half the width of the top of the rail head; and the center of the prism 3 coincides with the center line of the first mounting position 4 or the second mounting position 5.

[0040] The present application provides a rail positioning tool, comprising: a base and a prism 3, the base comprising a connected base body 1 and an extension 2, the bottom surface of the base body 1 being a first contact surface 11, the side of the extension 2 facing the first contact surface 11 being a second contact surface 21, and the first contact surface 11 and the second contact surface 21 being perpendicular to each other; the top surface of the base body 1 having a first mounting position 4 and a second mounting position 5, the prism 3 being detachably connected to the base body 1 at the first mounting position 4 and the second mounting position 5; the center line of the first mounting position 4 coincides with the second contact surface 21; the vertical distance between the center line of the second mounting position 5 and the second contact surface 21 is equal to half the width of the top of the rail head. The track positioning tooling provided by the present application can be placed directly on the rail, and the structure in which the first contact surface 11 and the second contact surface 21 are perpendicular to each other is used to make the second contact surface 21 contact the side of the rail, and at the same time, the first contact surface 11 contacts the top surface of the rail, thus completing the placement of the tooling; then the prism 3 is installed in the first mounting position 4 or the second mounting position 5 as needed, and the optical reflection principle of the prism is used. When the laser emitted by the total station hits the optical surface of the prism, the laser will be accurately reflected back to the total station at a specific angle. By analyzing the data of the reflected laser, the total station software can accurately calculate the specific position of the rail, thereby using the tooling provided by the present application to quickly and accurately identify and lock the center point or one side point of the top width of the rail head. The track positioning tooling provided by the present application cooperates with the total station to achieve efficient and accurate acquisition of measurement data, thereby achieving high efficiency in track center positioning and high precision in measurement work. The tooling's simple structure and rapid deployment capabilities significantly shorten on-site operation time and improve construction efficiency. Furthermore, the pluggable nature of the Prism 3 enhances the tooling's flexibility and convenience, facilitating rapid on-site deployment as well as storage and transportation.

[0041] Specifically, the center line of the first mounting position 4 coincides with the second contact surface 21. When the prism 3 is located at the first mounting position 4, the center point of the prism 3 also coincides with the second contact surface 21, that is, coincides with the side of the rail. The data measured at this time can represent the position of the edge point on one side of the rail; when the edge point on the other side needs to be measured, it is only necessary to turn the tooling provided in this application to the other side of the rail, and the edge points on both sides can be measured accurately and quickly.

[0042] The distance between the centerline of the second mounting position 5 and the second contact surface 21 is equal to half the width of the rail head top. This distance can indicate the center point of the rail head top width. Installing the prism 3 in the second mounting position 5 can measure the center point of the rail head top width.

[0043] In the present application, the extension portion 2 and the base body 1 can be perpendicular to each other or at other angles. As long as the first contact surface 11 and the second contact surface 21 are perpendicular to each other, the function of the tooling can be achieved.

[0044] Preferably, a groove 6 is provided at the junction of the first contact surface 11 and the second contact surface 21 .

[0045] Preferably, the width of the groove 6 is 4-6 mm.

[0046] A groove 6 is provided at the junction of the first contact surface 11 and the second contact surface 21 to prevent the irregularity of the track from affecting the placement of the tooling. The width of the groove 6 is preferably 4-6 mm, for example 5 mm.

[0047] Preferably, the base body 1 is provided with vertically penetrating mounting holes 7 at the first mounting position 4 and the second mounting position 5;

The prism 3 includes a prism body 31 and a mounting seat 32. The bottom of the mounting seat 32 has a mounting rod 33 that cooperates with the mounting holes 7. The cooperation between the mounting rod 33 and the mounting hole 7 allows for quick assembly and disassembly of the prism 3.

[0050] Preferably, the base body 1 is further provided with a transverse threaded hole 8, and the threaded hole 8 is connected to the side wall of the base body 1 and the mounting hole 7;

[0053] The end of the locking member 9 outside the base 1 may be provided with a knob for easy gripping and operation.

[0054] Preferably, the mounting base 32 includes a bottom plate and vertical plates connected to both ends of the bottom plate, and both sides of the prism body 31 are hinged to the vertical plates respectively.

[0055] Preferably, the mounting base 32 includes a base plate and upright plates connected to both ends of the base plate. The two sides of the prism body 31 are hinged to the upright plates on either side, allowing the angle of the prism 3 to be adjusted 360°. The prism 4 can then be positioned and fixed in any direction (appropriate damping can be provided to maintain a stable angle without applying external force). This adjustment function enables the total station to accurately capture the reflected signal from the prism 3 at any angle for measurement. Therefore, the total station can perform measurements in multiple directions without frequent relocation, meeting various measurement requirements, significantly saving measurement time, and improving measurement efficiency. Furthermore, by precisely adjusting the angle of the prism 3, it is possible to ensure that the laser beam is incident on the prism 3 at the optimal angle, thereby obtaining the most accurate reflected signal, which helps to improve the accuracy and reliability of the measurement.

[0056] Preferably, the base body 1 is further provided with at least one magnet 12 .

[0057] Preferably, the base body 1 is further provided with at least one magnet 12, which utilizes magnetic attraction to ensure that the tooling is placed stably. Magnetic attraction has the advantages of being simple, quick, and requiring no additional fixing devices, and can provide sufficient stability in a variety of situations to meet the use requirements of the tooling.

[0058] More preferably, the base body 1 is provided with two magnets 12 .

[0059] Preferably, the magnet 12 is disposed close to the first contact surface 11 .

[0060] Preferably, the magnet 12 is disposed close to the first contact surface 11, which is more conducive to maintaining installation stability.

[0062] The second contact surface 21 is also provided with a plurality of hemispherical contact bumps, and the top ends of the contact bumps are located in the same plane.

[0063] More preferably, the first contact surface 11 and the second contact surface 21 are respectively provided with a plurality of hemispherical contact protrusions to form two new contact surfaces, thereby changing the contact between the tooling and the rail from surface contact to point contact, thereby further reducing errors.
