Wherein the left side connecting rod and the right side connecting rod are matched and inserted through insertion holes in the end faces and bolts, and a spring is arranged at the insertion position, so that the length of the whole connecting rod is adjustable after the left side connecting rod and the right side connecting rod are inserted. Steel rail profile instruments are mounted at the outer ends of the left connecting rod and the right end surface through dovetail joint structures; after the left connecting rod and the right connecting rod are connected in an inserted mode, the overall length of the connecting rods is adjusted so that the two-side steel rail profile instruments can be installed on the two-side steel rails, and stable connection between the steel rail profile instruments and the steel rails is guaranteed through elastic force of the springs.

Description

Technical Field

[0002] This utility model relates to the field of railway construction technology and is a connecting crossbar used in a continuous rail profile measuring instrument. Background Technology

[0004] The continuous rail profile measuring instrument is a device for high-density, rapid, continuous, and massive data acquisition of rail profiles on site. It uses digital twin technology to reconstruct virtual 3D digital rails to intuitively and quantitatively display the three-dimensional rail status, digitally presenting the profile, defects, and turnout characteristics. It provides reliable quantitative data and three-dimensional image display for pre-grinding investigation, precise on-site operation, and post-grinding effect evaluation.

[0005] The main structure of the continuous rail profile measuring instrument includes a measuring structure and is equipped with corresponding running wheels. It can perform continuous measuring operations on the rail by manual pushing or mechanical towing.

[0006] Existing continuous rail profile measuring instruments consist of a main measuring unit and a connecting crossbar traveling mechanism, primarily designed for single-rail measurement applications. However, in practical applications, it has been found that measuring only one side results in low overall measurement efficiency, making it more suitable for manual, low-speed measurement scenarios. Furthermore, the single-sided crossbar traveling mechanism suffers from uneven weight distribution, requiring the intentional application of an unbalanced force during manual pushing operations. Therefore, it is not suitable for mounting on vehicle-mounted equipment. Utility Model Content

[0008] To address the aforementioned issues, this utility model proposes a rail profile measuring instrument connection mechanism, which is adapted to the bilateral field application of a continuous rail profile measuring instrument, enabling two continuous rail profile measuring instruments to be quickly combined into a measurement system, effectively improving the efficiency of field operations.

[0009] The connecting mechanism of this utility model rail profiler includes a left connecting rod, a right connecting rod, and a push rod.

[0010] The right end of the left connecting rod and the left end of the right connecting rod are connected by a pin through two holes designed on the end face, forming an integral rod-like structure. A spring is also fitted onto the pin, and the spring is fixed to the left end of the right connecting rod. A continuous rail profile measuring instrument is installed on the left end of the left connecting rod and the right end of the right connecting rod, respectively, on the left and right rails.

[0011] The push rod is connected to a connecting rod on one side and is located in the middle of the overall rod-shaped structure. The end of the push rod is designed with a hinge joint that hinges to the push rod hinge seat, forming a revolute joint B. Simultaneously, the push rod hinge seat is mounted on the side wall of one connecting rod via a bearing, forming a revolute joint A. The axis of revolute joint A is perpendicular to the axis of the left connecting rod; the axis of revolute joint B is perpendicular to the axis of revolute joint A.

[0012] After the left and right connecting rods are connected, the overall connecting rod length is adjusted so that the rail profile measuring instruments on both sides are installed on the rails. The spring force ensures a stable connection between the rail profile measuring instruments and the rails. Thus, the push rod installed on one side of the connecting rod can be used to move the overall measuring structure along the rails, and the two continuous rail profile measuring instruments can simultaneously collect the profiles of the two rails at the same cross-section.

[0013] A U-shaped retainer is designed on the outer end wall of the connecting rod on the side where the push rod is located, which cooperates with the push rod to clamp and fix the push rod.

[0014] The advantages of this utility model are:

[0015] 1. The rail profile measuring instrument connection mechanism of this utility model fully reuses the connection mechanism of the single-sided continuous rail profile measuring instrument. It is directly connected to the bottom dovetail groove of the existing continuous rail profile measuring instrument through the dovetail groove, which is convenient for modification.

[0016] 2. The connecting mechanism of the rail profile meter of this utility model has a spring structure designed in the middle of the entire structure to facilitate adaptation to changes in track gauge.

[0017] 3. The connecting mechanism of the rail profile measuring instrument of this utility model incorporates the battery inside the entire device, with internal wiring supplying power to the continuous rail profile measuring instruments on both sides, resulting in a compact overall structure.

[0030] The present invention will now be described in further detail with reference to the accompanying drawings.

[0031] The connecting mechanism of this utility model for a rail profile gauge includes a left connecting rod 1, a right connecting rod 2, and a push rod 3, as follows: Figure 1 As shown.

[0032] Among them, the left connecting rod 1 and the right connecting rod 2 are both rectangular cross-section rods of the same size, with hollow interiors.

[0033] like Figure 2 As shown, the right end face of the left connecting rod 2 is provided with circular insertion holes 101 of equal diameter arranged symmetrically in the front and back. The axis of the circular insertion holes 101 is along the left and right direction and intersects with the transverse center line of the end face.

[0034] like Figure 3 As shown, two cylindrical pins 201 are installed on the left end face of the right connecting rod 2, which are fitted into the circular insertion hole 101. The outer diameter of the two cylindrical pins 201 is equal to the diameter of the circular insertion hole 101, and the ends are hemispherical for easy insertion. At the same time, springs 202 are also fitted on the two cylindrical pins 201, and the ends of the springs 202 are fixed to the left end face of the right connecting rod 2.

[0035] Therefore, the left connecting rod 1 and the right connecting rod 2 can be connected by a circular insertion hole 101 and a cylindrical pin 102, achieving a coaxial connection between the left connecting rod 1 and the right connecting rod 2, forming an integral connecting rod; and after the two are connected, the corresponding circumferential walls of the left connecting rod 1 and the right connecting rod 2 are flush. During the connection process of the left connecting rod 1 and the right connecting rod 2, as the distance between them decreases, the front end of the spring 202 will contact the right end face of the left connecting rod 2; further increasing the connection force will compress the spring 202. Therefore, by adjusting the magnitude of the connection force, the degree of compression of the spring 202 can be adjusted, thereby changing the length of the integral connecting rod.

[0036] To further ensure the stability of the connection between the left connecting rod 1 and the right connecting rod 2, strip-shaped holes 103 are designed along the left-right direction on the front and rear side walls near the right end of the left connecting rod 1. The length of the strip-shaped holes is designed according to the compression of the spring 202, ensuring that after the cylindrical pin 201 is inserted into the cylindrical insertion hole 101, the end of the cylindrical pin 201 can be located between the two strip-shaped holes 102 within the compressibility range of the spring 202. At the same time, openings are designed at the ends of the two cylindrical pins 201, with the axis of the openings being coaxial and perpendicular to the axis of the cylindrical pins 201. Thus, after the left connecting rod 1 and the right connecting rod 2 are connected and the spring 202 is compressed, two pins 103 with an outer diameter equal to the width of the strip-shaped holes are inserted through the two strip-shaped holes 102 and into the openings at the ends of the two cylindrical pins 201, respectively, thus longitudinally limiting the ends of the two pins 201; combined with the support of the right end of the left connecting rod 2 for the cylindrical pins 201, the overall stability of the connecting rod is increased. The two pins 103 mentioned above can be connected to the front and rear side walls of the left connecting rod 1 respectively by ropes, which facilitates the use of the pins 103.

[0037] The left end of the left connecting rod 1 and the right end of the right connecting rod 2 are connecting ends, each with a dovetail tenon 4 designed to mate with the dovetail tenon on the side of the continuous rail profile measuring instrument 6. This allows the two continuous rail profile measuring instruments 6 to be fixedly installed at the connecting ends of the left connecting rod 1 and the right connecting rod 2, respectively. Each of the two continuous rail profile measuring instruments 6 is equipped with an independent power supply battery 5, which is mounted on its respective battery holder 501. The battery inlets, located in the middle of the top sidewalls of the left connecting rod 1 and the right connecting rod 2, are placed inside the left connecting rod 1 and the right connecting rod 2. The battery holder 501 is further secured by screws through a circumferential shoulder that overlaps with the sidewall. The two power supply batteries 5 power the two continuous rail profile measuring instruments 6, which are connected by internal wiring within the left connecting rod 1 and the right connecting rod 2.

[0038] In application, the rail profile measuring mechanism of this utility model first installs the continuous rail profile measuring instrument 6 at the connection end between the left connecting rod 1 and the right connecting rod 2. Then, the left connecting rod 1 and the right connecting rod 2 are inserted together, forming an overall measuring structure with continuous rail profile measuring instruments 6 at both ends. By applying a relative insertion force to the left connecting rod 1 and the right connecting rod 2, the spring 202 between them is compressed. By adjusting the magnitude of the insertion force, the compression of the spring 202 is changed, and the length of the overall measuring structure is adjusted so that the continuous rail profile measuring instruments 6 at both ends are placed on the rails on both sides. The continuous rail profile measuring instruments are then installed and adjusted on the rails. Figure 5 As shown. Thus, the elastic force of the spring 202 ensures a stable connection between the continuous rail profile measuring instrument 6 and the rail. The push rod 3 can push the overall measuring structure, so that the continuous rail profile measuring instruments 6 at both ends can move synchronously along the rails on both sides.

[0039] To ensure the stability of the overall measuring structure during the movement of the push rod 3, the push rod 3 should be positioned as close as possible to the center of the overall measuring structure to ensure stable movement along the rail. Therefore, in this invention, the left connecting rod 1 is designed to be approximately 5 cm longer than the right connecting rod 2. This allows for the design of mounting holes on the side wall within 5 cm of the right end of the left connecting rod 1. A rotating pair A is formed at the mounting hole by a bearing-mounted push rod hinge seat 301, with the axis of rotation A perpendicular to the axis of the left connecting rod 1. Furthermore, a rotating pair B is formed by hinged joints on the push rod hinge seat 301 and the bottom end of the push rod 3, with the axis of rotation B perpendicular to the axis of rotation pair A. This allows the push rod 3 to rotate around rotating pairs A and B, enabling it to perform lifting and rotating actions.

[0040] Meanwhile, this utility model also has a U-shaped bracket 104 designed on the top surface of the left connecting rod 1, on the side connected to the push rod 3, near the left end of the left connecting rod 1. The push rod 3 can be rotated through the aforementioned two rotating joints, so that the push rod can be laid flat towards the top surface of the left connecting rod 1, and then the push rod 3 can cooperate with the U-shaped bracket 104, and the U-shaped bracket 104 can clamp the push rod 3, so as to realize the folding and storage of the push rod 3.

[0041] In summary, the rail profile measuring device connecting mechanism of this utility model quickly combines two continuous rail profile measuring instruments into a complete measuring system. By controlling the compression degree of the springs between the left and right connecting rods, the entire measuring device can be set between rails with different spacings, adapting to scenarios with varying track gauges. Simultaneously, the spring force presses the two continuous rail profile measuring instruments firmly onto the rails on both sides. A push rod pushes the entire device along the rails, allowing the two continuous rail profile measuring instruments to simultaneously collect the profiles of two rails at the same cross-section.
