Technical Field

[0001] This invention mainly relates to an auxiliary device for measuring track dynamics, and more specifically to an auxiliary device for precise and rapid positioning and bonding of wheel-rail force strain gauges. Background Technology

[0002] Currently, wheel-rail force testing primarily relies on manual marking with steel rulers and needles for positioning. During installation, the strain gauge crosshairs are aligned visually with the crosshairs drawn on the rail. This method is not only inaccurate but also cumbersome, time-consuming, and labor-intensive, posing a significant challenge to the testing personnel's skills. To improve the efficiency and accuracy of wheel-rail force testing and reduce construction difficulty, this invention designs a strain gauge positioning auxiliary device. Summary of the Invention

[0003] The main technical problem solved by this invention is to provide an auxiliary device for precise and rapid positioning and pasting of wheel-rail force strain gauges. This eliminates the need for marking lines on the rail and manually aligning and pasting the crosshairs on the strain gauges with the lines marked on the rail, thereby achieving the goal of saving time and effort and ensuring accurate wheel-rail force testing. It also reduces the operational difficulty for testing personnel and improves the accuracy of test data.

[0004] To address the aforementioned technical problems, this invention relates to an auxiliary device for track dynamics measurement, and more specifically, to an auxiliary device for precise and rapid positioning and bonding of wheel-rail force strain gauges. The device includes a patch I, a crease I, a patch II, a magnetic block I, a support plate, a crease II, a patch III, a magnetic block II, a crease III, and a patch IV. This eliminates the need for marking lines on the rail and manually aligning and bonding the strain gauge crosshairs with the marked lines on the rail, thus achieving time-saving, labor-saving, and accurate wheel-rail force testing. It also reduces the operational difficulty for testing personnel, thereby improving the accuracy of the test data.

[0005] Patches I have intermediate plates I and cavities I. There are two cavities I, and the intermediate plates I separate patches I into two cavities I. Patches III have intermediate plates II, a center indicator, and cavities II. There are two cavities II, and the intermediate plates II separate patches III into two cavities II. The center indicator is located on the intermediate plates II.

[0006] There is a crease I between patch 1 and patch 2, with patch 1 positioned above patch 2. Magnetic block I is fixedly connected to patch 1, and is located on the front of patch 1. There is a crease II between patch 2 and patch 3, with patch 2 positioned above patch 3. A support plate is fixed to patch 2, and is located on the front of patch 2. There is a crease III between patch 3 and patch 4, with patch 3 positioned above patch 4. Magnetic block II is fixedly connected to patch 3, and is located on the front of patch 3.

[0007] As a further optimization of this solution, the surface of the patch II3 in the wheel-rail force strain gauge precise and rapid positioning and pasting auxiliary device of the present invention is a plane rather than a curved surface.

[0008] As a further optimization of this solution, the present invention provides a wheel-rail force strain gauge precise and rapid positioning and bonding auxiliary device with multiple magnetic blocks I4 and II8.

[0009] As a further optimization of this solution, the support plate 5 of the wheel-rail force strain gauge precise and rapid positioning and pasting auxiliary device of the present invention has multiple plates.

[0010] As a further optimization of this solution, the shape and size of the cavities I1-2 and II7-3 in the wheel-rail force strain gauge precise and rapid positioning and bonding auxiliary device of the present invention can be adjusted by grinding.

[0011] The beneficial effects of the wheel-rail force strain gauge precise and rapid positioning and pasting auxiliary device of the present invention are: it eliminates the steps of marking the rail and manually aligning and pasting the crosshairs of the strain gauge with the crosshairs marked on the rail, so as to achieve the purpose of saving time and effort and accurate testing of wheel-rail force, and can reduce the operation difficulty of the test personnel, thereby improving the accuracy of the test data.

[0016] Specific Implementation Method 1: The following is combined with... Figure 1 , 2This invention relates to an auxiliary device for measuring track dynamics, and more specifically, to an auxiliary device for precise and rapid positioning and pasting of wheel-rail force strain gauges. The device includes a patch I1, a crease I2, a patch II3, a magnetic block I4, a support plate 5, a crease II6, a patch III7, a magnetic block II8, a crease III9, and a patch IV10. This eliminates the need for marking lines on the rail and manually aligning and pasting the strain gauge crosshairs with the marked lines on the rail, thus achieving time-saving, labor-saving, and accurate wheel-rail force testing. It also reduces the operational difficulty for testing personnel, thereby improving the accuracy of the test data.

[0017] Patches I1 have an intermediate piece I1-1 and two cavities I1-2. The intermediate piece I1-1 separates patches I1 into two cavities I1-2. A crease I2 exists between patches I1 and II3, with patch I1 positioned above patch II3. A magnetic block I4 is fixedly connected to patch I1, located on the front of patch I1. Patches I1 are attached to the track waist area to connect the invention to the track waist area. Patches I1 are connected to the track via the magnetic block I4, and patches I1 can be separated from the track.

[0018] Patches III7 have an intermediate piece II7-1, a center indicator 7-2, and two cavities II7-3. The intermediate piece II7-1 separates the patches III7 into two cavities II7-3. The center indicator 7-2 is located on the intermediate piece II7-1. Patches III7 are attached to the upper surface of the track bottom to fix the invention to the bottom of the track. Magnetic block II8 is fixedly connected to patches III7, and is located on the front of patches III7. Patches III7 are connected to the track through magnetic block II8, and patches III7 can be separated from the track. During the process of attaching patches III7 to the track bottom, after adjusting the tip of the center indicator 7-2 to align with the center position of one span of the track rail, patches III7 are then attached to the track bottom.

[0019] There is a crease II6 between patch II3 and patch III7, with patch II3 positioned above patch III7. Support plate 5 is fixed to patch II3, located on the front of patch II3. The rail web and rail bottom are bent at a certain angle. Patch II3 serves as a transition connecting patch I1 and patch III7; patch II3 is not in contact with the rail. Support plate 5 is used to enhance the rigidity of patch II3 and prevent it from bending.

[0020] There is a crease III9 between patch III7 and patch IV10, with patch III7 located above patch IV10. Patch IV10 is attached to the side portion of the bottom of the track. Specific Implementation Method Two: The following is combined Figure 1 , 2This embodiment further explains embodiment one. The surface of patch II3 is planar, not curved. Because patch II3 is designed as a planar surface, patch I1 and patch III7 contact the track during application. Patch II3 does not need to adhere to the connection between the track bottom and track waist, greatly increasing ease of use during operation. Specific implementation method three: The following is combined Figure 1 , 2 This embodiment further explains embodiment one. There are multiple magnetic blocks I4 and magnetic blocks II8. The number of magnetic blocks I4 and magnetic blocks II8 can be adjusted as needed to make the connection more stable. Specific implementation method four: The following is combined Figure 1 , 2 This embodiment further explains embodiment one, and the support plate 5 is described in multiple ways. The number of support plates 5 can be adjusted according to the rigidity of patch II 3 and support plate 5 to prevent patch II 3 from bending. Specific implementation method five: The following is combined Figure 1 , 2 This embodiment further explains Embodiment 1. The shape and size of cavities I1-2 and II7-3 can be adjusted by grinding. Cavities I1-2 and II7-3 are used to place strain gauges. After the center indicator 7-2 is aligned with the center position of one span of the track, patches I1, II3, III7, and IV10 are attached to the corresponding positions. Then, strain gauges can be directly placed in cavities I1-2 and II7-3, eliminating the need to mark crosshairs on the track and align the strain gauges with the crosshairs, thus improving work efficiency and accuracy. Depending on the model and shape of the strain gauges, the shape of cavities I1-2 and II7-3 can be adjusted by grinding to accommodate the strain gauges. When the strain gauges are attached and assembled into a bridge, the strain gauge connecting lines pass through cavities I1-2 and II7-3, bypassing the outside of the invention and connecting to each other as a whole. Therefore, after the strain gauge bridge is completed, the invention can be removed for repeated use, reducing on-site workload.
