This work is crucial for railway design, construction, and subsequent maintenance.

[0003] In the prior art, rail longitudinal section measurements are usually performed using a total station. However, when using a total station for detection, the placement of the reflector is difficult to determine, which can easily lead to measurement deviations due to the position of the reflector. Utility Model Content

[0016] Optionally, it also includes:

[0017] a first friction plate, disposed on the support plate;

[0018] a second friction plate disposed on the support frame, wherein when the support frame is raised or lowered, the second friction plate approaches or moves away from the first friction plate, and when the second friction plate abuts against the first friction plate, the friction force between the first friction plate and the second friction plate is used to prevent the support frame from rotating relative to the mounting hole;

[0019] An elastic member, with two ends respectively arranged on the second friction plate and the support plate, and the elastic member is used to provide a force for the second friction plate to approach the first friction plate.

[0020] Optionally, the second friction plate is threadedly connected to the support frame.

The support plate should be long enough to span two adjacent rails, ensuring it remains securely positioned on the rails without wobbling. The support plate has a mounting hole in its center for mounting the reflector. The mounting hole is positioned to ensure the reflector accurately receives the signal from the total station.

[0028] The reflector is installed in the mounting hole to receive the signal transmitted by the total station.

[0038] Example 1

[0039] Reference Figure 1~Figure 2 , which is the first embodiment of the utility model, proposes a device for rail longitudinal section survey, including a support plate 100 with both ends respectively overlapped on two rails, and a mounting hole 110 is provided in the center of the support plate 100; a reflector 200 is arranged in the mounting hole 110, and the reflector 200 is used to receive the signal transmitted by the total station.

[0040] In this embodiment, the ends of the support plate 100 are respectively attached to two rails to ensure the stability and accuracy of the device on the rails. The support plate 100 should be long enough to span two adjacent rails, ensuring that it can be firmly placed on the rails without shaking. The support plate 100 has a mounting hole 110 in the center for mounting the reflector 200. The location of the mounting hole 110 ensures that the reflector 200 can accurately receive the signal from the total station.

[0041] Reflector 200 is positioned within mounting hole 110 and is used to receive signals transmitted by the total station. Reflector 200, typically a mirror or reflector, reflects the laser signal emitted by the total station back to the instrument for reception and measurement. Positioning reflector 200 within mounting hole 110 not only facilitates installation but also facilitates positioning of reflector 200.

[0042] Furthermore, it also includes a first support rod 310, one end of which is set on the support plate 100, and the other end is facing the ground; a second support rod 320, one end of which is set on the first support rod 310, and the other end is facing the side away from the reflector 200. After the support plate 100 is overlapped on the rail, the other end of the second support rod 320 is in contact with the side of the rail.

[0043] In this embodiment, one end of the first support rod 310 is mounted on the support plate 100, with the other end facing the ground. One end of the second support rod 320 is mounted on the first support rod 310, with the other end facing away from the reflector 200. When the support plate 100 is attached to the rail, the other end of the second support rod 320 abuts against the side of the rail. The second support rod 320 not only ensures the verticality of the support plate 100 but also facilitates its positioning.

[0044] Furthermore, the first support rod 310 and the second support rod 320 are arranged perpendicularly.

[0045] In this embodiment, when the support plate 100 is attached to the rail, the other end of the second support rod 320 abuts against the side of the rail, which helps to enhance the stability of the entire device. The vertical arrangement of the first support rod 310 and the second support rod 320 can better disperse forces from different directions, thereby improving the overall stability of the device.

[0046] Furthermore, the reflector 200 includes a support frame 210 that is raised and lowered and rotatably arranged in the mounting hole 110, the rotation axis of the support frame 210 is colinear with the axis of the mounting hole 110, and the support frame 210 slides along the axis direction of the mounting hole 110; the prism 220 is rotatably arranged on the support frame 210, and the rotation axis of the prism 220 is perpendicular to the axis direction of the support frame 210. After the support frame 210 slides, the prism 220 approaches or moves away from the support plate 100.

[0047] In this embodiment, the support frame 210 can be raised and lowered and rotated within the mounting hole 110, with its rotation axis being collinear with the axis of the mounting hole 110. This facilitates not only height adjustment but also angle adjustment of the support frame 210, allowing the prism 220 on the support frame 210 to adapt to different total station placement positions.

[0048] The prism 220 is rotatably mounted on the support frame 210 , with its rotation axis being perpendicular to the axis of the support frame 210 . The rotation of the prism 220 facilitates adjustment of the orientation of the prism 220 , further enhancing the flexibility of the device.

[0049] Furthermore, it also includes a first friction plate 400 arranged on the support plate 100; the second friction plate 230 is arranged on the support frame 210. After the support frame 210 is raised or lowered, the second friction plate 230 approaches or moves away from the first friction plate 400. After the second friction plate 230 abuts against the first friction plate 400, the friction force between the first friction plate 400 and the second friction plate 230 is used to prevent the support frame 210 from rotating relative to the mounting hole 110; the two ends of the elastic member 240 are respectively arranged on the second friction plate 230 and the support plate 100, and the elastic member 240 is used to provide a force for the second friction plate 230 to approach the first friction plate 400.

[0050] In this embodiment, the first friction plate 400 is mounted on the support plate 100, providing a base surface for friction. The second friction plate 230 is mounted on the support frame 210 and moves closer to or further away from the first friction plate 400 as the support frame 210 is raised or lowered. The elastic member 240, with its ends connected to the second friction plate 230 and the support plate 100, provides a force that forces the second friction plate 230 toward the first friction plate 400.

[0051] When the second friction plate 230 approaches and contacts the first friction plate 400, the friction between the two prevents the support frame 210 from rotating relative to the mounting hole 110. This design ensures that once the prism 220 is positioned, it remains stable unless sufficient force is applied to overcome the friction. To adjust the angle of the support frame 210, simply compress the elastic member 240 and move the second friction plate 230 away from the first friction plate 400, allowing the support frame 210 to rotate easily, making adjustment easier for the operator.

[0052] Furthermore, the second friction plate 230 is threadedly connected to the support frame 210 .

[0053] In this embodiment, the second friction plate 230 and the support frame 210 are designed to be separated and connected by threads, which makes it easier to install the support frame 210.

[0054] Furthermore, the rotation between the prism 220 and the support frame 210 is damped.

[0055] In this embodiment, the prism 220 can be fixed at a certain angle after being rotated by the damping between the prism 220 and the support frame 210. The damping design is more convenient for the operator to use.

[0056] Example 2

[0057] Reference Figure 3 , which is the second embodiment of the present utility model. The second embodiment is different from the first embodiment in that: the support plate 100 includes: a main body 120, a first support rod 310 is arranged on the main body 120; a sliding frame 130, which is slidably arranged on the main body 120, and the sliding frame 130 slides close to or away from the first support rod 310. The sliding frame 130 is located below the main body 120, and the sliding frame 130 has a mounting hole 110. The two ends of the elastic member 240 are respectively arranged on the second friction plate 230 and the sliding frame 130.

[0058] In this embodiment, the support plate 100 is composed of a main body 120 and a sliding frame 130. After the sliding frame 130 slides, the position of the mounting hole 110 can be changed, thereby changing the installation position of the reflector 200, further improving the applicability of the device.

[0059] Furthermore, the main body 120 has an oblong hole 121 , and the sliding frame 130 is fixed to the main body 120 via bolts and the oblong hole 121 .

[0060] In this embodiment, the sliding frame 130 is fixed to the main body 120 by bolts. When the sliding frame 130 needs to slide, the nut can be loosened to allow the sliding frame 130 to slide in the oblong hole 121. After the sliding frame 130 is adjusted to the specified position, the bolts can be tightened to fix the sliding frame 130 on the main body 120, thereby preventing the sliding frame 130 from moving during detection and affecting the detection results.

[0061] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention, and all of these should be included in the scope of the claims of the present invention.
