[0020] In order to more clearly illustrate the embodiments of the utility model or the technical solutions in the prior art, the drawings required for use in the embodiments or the description of the prior art will be briefly introduced below. Obviously, the drawings described below are only some embodiments of the utility model. For ordinary technicians in this field, other drawings can be obtained based on these drawings without paying creative work.

[0021] like Figure 1 , Figure 2 Shown is a device for collecting and positioning the center data of a ballasted track rail, comprising a base 1 and a horizontal support mechanism 2.

[0022] The bottom surface of the base 1 has a slot 1.1 that fits with the rail head of the rail, the top surface of the slot 1.1 is an arc surface that matches with the top surface of the rail head of the rail, and the side surface of the slot 1.1 is a straight surface that fits with the side surface of the rail head; the base 1 is clamped on the rail head of the rail through the slot 1.1; the top surface and side surface of the slot 1.1 fit with the rail head of the rail so that the longitudinal symmetry surface of the slot 1.1 is aligned with the symmetry surface of the cross section of the rail. A conical hole 1.2 is provided on the base 1 and connected to the slot 1.1 from top to bottom. The axis of the conical hole 1.2 is located on the longitudinal symmetry plane of the slot 1.1, and the longitudinal symmetry plane is a symmetry plane parallel to the length direction of the rail, that is, the conical hole 1.2 is centered relative to the cross section of the rail; the large end of the conical hole 1.2 faces upward and the small end faces downward, and the diameter of the small end of the conical hole 1.2 only allows the tip of the total station measuring rod to pass through and touch the rail head of the rail. The diameter of the small end of the conical hole 1.2 is 1 mm, and the diameter of the large end of the conical hole 1.2 is 40 mm. The conical hole 1.2 allows the total station measuring rod to swing around the small end of the conical hole 1.2 as the center.

[0023] A square groove 1.3 is provided on the base 1 above the conical hole 1.2, and the horizontal support mechanism 2 is limited in the square groove 1.3. Four linear elastic telescopic parts are provided on the horizontal support mechanism 2, namely, front, rear, left and right parts. A support hole 2.2 is provided in the middle of the four linear elastic telescopic parts. The four linear elastic telescopic parts are in sliding contact with the four sides of the square groove 1.3 respectively. The measuring rod of the total station extends into the conical hole 1.2 after passing through the support hole 2.2. When the four linear elastic telescopic parts are in a static state, the support hole 2.2 is coaxial with the conical hole 1.2.

[0024] In areas where the rails are sloping, the total station measuring rod needs to be adjusted to a vertical position with respect to the horizontal plane. At this time, the total station measuring rod is swung with the small end of the conical hole 1.2 as the origin. The total station measuring rod pushes the horizontal support mechanism 2 to move in the square groove 1.3. The level bubble on the total station measuring rod is used to observe whether the total station measuring rod is vertical.

[0025] After the measurement is completed, the external force on the total station measuring rod is removed, the four linear elastic telescopic parts reset the horizontal support mechanism 2, the total station measuring rod returns to the center, the total station measuring rod is located in the symmetry plane of the cross section of the rail, and the total station measuring rod is perpendicular to the rail; that is, in sections where the rails are horizontal, measurement can be performed without adjusting the total station measuring rod.

[0026] The square groove 1.3 on the base 1 is open at the top; it also includes a cover 3, which is connected to the base 1 and covers the top of the square groove 1.3 to limit the upward and downward movement of the horizontal support mechanism 2. The cover 3 is provided with a through hole 3.1 coaxial with the conical hole 1.2, and the diameter of the through hole 3.1 is larger than the large end diameter of the conical hole 1.2. The cover 3 is connected to the base 1 by screws at the four corners.

[0028] like Figure 5 As shown: a hole is opened in the center of the slider 2.1, and a rubber ring 6 with a circular cross-section is embedded in the hole. The inner hole of the rubber ring 6 serves as a supporting hole 2.2; through the rubber ring 6, the slider 2.1 leaves room for the total station measuring rod to move while always providing support for the total station measuring rod.

[0029] like Figure 3 As shown: two bolts 4 are connected to the cover 3, and the two bolts 4 are located on both sides of the through hole 3.1. The bolts 4 radially penetrate into the through hole 3.1, and the bolts 4 are threadedly screwed with the cover 3. One end of the bolt 4 located in the through hole 3.1 is connected to the clamp 5 through a rotary joint; when the total station measuring rod needs to be moved to other measuring positions, the two bolts 4 on the cover 3 are adjusted at the same time, and the two bolts 4 clamp the total station measuring rod through the clamp 5, and the total station measuring rod is connected to the cover 3, and when the total station measuring rod is lifted, the cover 3 and the base 1 are lifted together.
