[0041] In order to make the purpose, technical solutions and advantages of the present application clearer, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention. In addition, the technical features involved in each embodiment of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0042] like Figure 1 As shown, in this embodiment, the pile positioning device includes a measuring lens 1, an angle adjustment spiral ring 2 and a distance adjustment spiral ring 3. The measuring lens 1 includes two half lenses 11 of the same shape and mirror symmetry. The half lenses 11 are engraved with engraved lines 12. In this embodiment, as shown Figure 2 The planes on which the half mirrors 11 move are parallel to each other and at a certain distance from each other, and as shown in Figure 4 , 5 As shown, the projections of the two half-mirrors 11 on the viewing angle of the half-mirror 11 are symmetrical to each other, and the projections of the engraved lines 12 are also mirror-symmetrical. The angle-adjusting spiral ring 2 is rotatably arranged on the lens barrel 5, and its inner wall and the half-mirror 11 are fixedly connected to each other, so that when the angle-adjusting spiral ring 2 rotates, the half-mirror 11 can be driven to rotate together. The distance-adjusting spiral ring 3 includes a distance-adjusting ring 31, the inner wall of which is convex inwardly and the radius gradually shrinks. The radius sheet is abutted against the inner wall of the distance-adjusting ring 31 through the connecting device 4. When the distance-adjusting ring 31 rotates relative to the half-mirror 11, the connecting device 4 can drive the half-mirror 11 to shrink inwardly.

[0043] As a further optimization of this embodiment, Figure 3 As shown, an angle adjustment groove 52 is opened on the lens barrel 5, and the angle adjustment groove 52 is vertically arranged on the outer wall of the lens barrel 5 and has a certain curvature. The angle adjustment spiral ring 2 includes an angle adjustment operating ring 21 and an angle adjustment inner lining ring 22. The angle adjustment operating ring 21 is rotatably arranged on the outer wall of the lens barrel 5, and the angle adjustment inner lining ring 22 is rotatably arranged on the inner wall of the lens barrel 5. The angle adjustment operating ring 21 and the angle adjustment inner lining ring 22 are connected by a connecting column 23, and the connecting column 23 is located in the angle adjustment groove 52. The angle adjustment groove 52 occupies a certain angle so that the connecting column 23 slides at a certain angle in the angle adjustment groove 52, thereby allowing the angle adjustment operating ring 21 to rotate relative to the lens barrel 5.

[0044] Further, such as Figure 2 , 5 As shown in the figure, the end of the angle adjustment inner liner ring 22 close to the eyepiece 6 is provided with a mounting groove plate 221, and the two half lenses 11 are slidably arranged in the center of the mounting groove plate 221 and are slidably connected to each other with the mounting groove plate 221. There are multiple sliding connection methods for the half lenses 11, such as providing a groove in the center of the mounting groove plate 221, and the two half lenses 11 are slidably connected to each other with the mounting groove plate 221. Figure 2The manner shown is staggered in the groove, or in other embodiments, two grooves can be provided, and each half mirror 11 is provided in one groove.

[0045] Furthermore, a movable groove 2211 is provided on the mounting groove plate 221, and the measuring lens 1 is arranged in the movable groove 2211. Each half lens 11 always partially overlaps when sliding in the movable groove 2211. The reason for selecting this solution is that it is easier to process.

[0046] Furthermore, Figure 4 As shown, the angle adjustment inner liner ring 22 and / or the mounting slot plate 221 are provided with a connecting slot 41. It should be noted that Figure 4 Because the half-mirror 11 is relatively large, the connecting groove 41 partially extends out of the angle adjustment inner lining ring 22 and is blocked in front of the lens barrel 5, and is not fixedly connected to the lens barrel 5. In some embodiments, the half-mirror 11 can be reduced in size or other devices such as the lens barrel 5 can be increased in size, so that the connecting groove 41 is completely set inside the angle adjustment inner lining ring 22 or the mounting groove plate 221, and the connecting device 4 is set in the connecting groove 41, and each connecting device 4 is set at one end of the half-mirror 11 away from the other half-mirror 11, and the two connecting devices 4 are arranged opposite to each other.

[0047] Going a step further, Figure 6 As shown, the connecting device 4 includes a connecting top pile 42, a top pin 43 and a rebound device 44. The connecting top pile 42 is fixedly connected to the half mirror 11 to prevent the rebound device 44 from applying force to damage the half mirror 11. One end of the top pin 43 abuts against the inner wall of the distance adjustment ring 31, and the other end is fixedly connected to the connecting top pile 42. One end of the rebound device 44 abuts against the connecting top pile 42, and the other end abuts against the connecting slide groove 41. When the distance adjustment spiral ring 3 rotates, the top pin 43 slides on the inner wall of the distance adjustment ring 31. Because the inner wall of the distance adjustment ring 31 gradually shrinks inward, the top pin 43 also gradually squeezes inward, driving the half mirror 11 to shrink inward. After rotating in the opposite direction, the top pin 43 and the half mirror 11 gradually return to their positions under the action of the rebound device 44.

[0048] Furthermore, a limiting groove 51 is provided on the lens barrel 5, and a limiting slider 211 is provided on the inner wall of the angle adjustment operating ring 21. The limiting ring groove and the limiting slider 211 cooperate with each other to limit the movement of the angle adjustment operating ring 21 in the long axis direction of the lens barrel 5, reduce the misalignment of the angle adjustment operating ring 21, and also facilitate the engraving of scales on the lens barrel 5 to indicate the angle.

[0049] As an optimization of this embodiment, the distance adjustment ring 31 is connected to the lens barrel 5 through a thread, and the eyepiece 6 is fixedly arranged at the end of the distance adjustment ring 31 away from the lens barrel 5. The threaded connection is used on the one hand because the friction of the thread itself is large, which will prevent the distance adjustment ring 31 from returning to its original position under the rebound action of the connecting device 4; on the other hand, it is convenient for disassembly, so that the total station can be restored to normal use.

[0050] This embodiment also includes a total station, which includes a pipe pile positioning device arranged between the total station lens barrel 5 and the eyepiece 6.

[0051] This embodiment also includes a measurement method based on the total station,

[0052] S1. Align the total station roughly with the pile to be measured, and visually align it with the approximate center of the pile. The pile measured in this embodiment is a cylindrical pile of a cross-river bridge, about 100 meters from the shore, and it is difficult to approach due to strong winds and waves;

[0053] S2. Rotate the angle adjustment spiral ring 2 so that the engraved line 12 and the edges of both sides of the tube turn are parallel to each other;

[0054] S3. Rotate the pitch-adjusting spiral ring 3 so that the measuring lenses 1 are close to or away from each other, so that the scribed line 12 and the edge of the pile are close to each other;

[0055] S4 repeat S2-S3 several times, so that the engraved line 12 and the edge of the pile are aligned;

[0056] S5. Use the total station to read the position data of the central symmetrical points of the two engraved lines 12, repeat the measurement three times at the same position, change three measurement locations that are 10 meters apart and on different lines, repeat the measurement three times for each location, and take the average value to obtain the coordinates of the center line of the pile.

[0057] The present application is not limited to the above-mentioned implementation modes. For ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present invention. These improvements and modifications are also considered to be within the scope of protection of the present invention.
