Description

Technical Field

[0001] This application relates to the field of turnout component measurement technology, and in particular, to a rail inclination measuring device. Background Technology

[0002] The information provided in this section is for the purpose of generally presenting the background of this application. To the extent described in this section, the work of the currently named inventors and aspects of the description that may not constitute prior art at the time of filing are neither explicitly nor implicitly considered to be prior art of this application.

[0003] For measuring the inclination of turnout components such as switch rails, fork joints, frog rails, and the non-working and working sides of the main rail head, specialized measuring tools are required. For example, Chinese Patent Publication No. CN206832203U discloses a railway track inclination measuring device, which includes a flatness reference plate, a housing fixedly installed on one side of the flatness reference plate, a handle fixedly installed on the top of the housing, a control panel embedded in one side of the housing, a measuring controller electrically connected to the control panel installed inside the housing, an electrically retractable measuring tape roll installed on one side of the measuring controller, a laser rangefinder electrically connected to the measuring controller fixedly installed on the inner wall of the housing on the side of the electrically retractable measuring tape roll, and a laser probe embedded in one side of the laser rangefinder; a measuring reflector is snapped onto one end of the flatness reference plate. The advantages are as follows: this solution can simultaneously measure the track inclination using a measuring tape, and calculate the track inclination by the ratio of the measured length to the inclination deviation, facilitating segmented measurement of track inclination, and is convenient to use with high measurement accuracy.

[0004] However, existing tilt measuring devices require auxiliary calculations to obtain the tilt angle, making the measurement less intuitive and less efficient. Furthermore, traditional measurement methods require the angle gauge to be placed close to the top surface of the base and against the non-working edge of the rail head to measure the angle. This results in a fixed angle gauge size, which cannot adapt to rail components of different heights, limiting the measurement range. Additionally, traditional measurement methods are cumbersome to operate, and the measurement accuracy is significantly affected by height limitations. Utility Model Content

[0031] A rail inclination measuring device includes a base assembly 1, an adjusting component 2, an angle gauge 3, a sliding contact module 4, and a limiting assembly.

[0032] The base assembly 1 includes a base plate 11 and a support column 12. The base plate 11 is used to support the rail to be tested. The support column 12 is vertically arranged on the base plate 11. The adjusting member 2 is slidably sleeved on the support column 12. The limiting assembly is used to lock and fix the adjusting member 2 after it has been slidably adjusted to the desired position. Angle ruler 3 is rotatably arranged on the side wall of the adjusting member 2. Angle ruler 3 is rotatably arranged on the side wall of the adjusting member 2 along the vertical plane. Angle ruler 3 and / or the side wall of the adjusting member 2 are provided with an angle scale for indicating the rotation angle of angle ruler 3. Angle ruler 3 has a limiting hole 32 radially arranged along its axis of rotation. The sliding abutment module 4 passes through the limiting hole 32. Angle ruler 3 is used to drive the sliding abutment module 4 to rotate and make the sliding abutment module 4 face the inclined surface to be tested of the rail to be tested. The sliding abutment module 4 is used to slide along the limiting hole 32 to abut the inclined surface to be tested of the rail to be tested.

[0033] Here, "adjusting element 2" refers to a structure that is slidably sleeved on the support column 12. In some embodiments, the adjusting element 2 is a circular plate-shaped structure with a central through hole, and the side wall of the adjusting element 2 is provided with an angle scale.

[0034] The limiting assembly includes a first locking member 6. The adjusting member 2 has a first locking screw hole. The first locking member 6 passes through the first locking screw hole and presses against the support column 12 to lock and limit the adjusting member 2 to the support column 12. The first locking member 6 can be a bolt or a screw, facilitating manual adjustment or adjustment using conventional tools for quick locking and fixing of the adjusting member 2. In some embodiments, the first locking member 6 includes a screw with a first handle at its top. Rotating the first handle allows the first locking member 6 to be turned, facilitating manual adjustment of the height of the adjusting member 2.

[0035] The rail inclination measuring device of this application supports the rail to be measured through the base plate 11 of the base assembly 1. The adjusting component 2 is slidably mounted on the support column 12 on the base plate 11. The adjusting component 2 can drive the angle ruler 3 to rise and fall. At the same time, the angle ruler 3 is rotatably mounted on the adjusting component 2. In addition, the sliding abutment module 4 is slidably mounted in the limiting hole 32 of the angle ruler 3. The adjusting component 2 can drive the angle ruler 3 to rise and fall to a suitable height. Then, the angle ruler 3 drives the sliding abutment module 4 to rotate toward the inclination surface to be measured of the rail. Pushing the sliding abutment module 4 to abut the inclination surface to be measured, the inclination angle of the inclination surface to be measured can be read directly by the rotation angle of the angle ruler 3. The operation is very convenient and intuitive, which greatly improves the measurement efficiency and can well adapt to the measurement needs of rails of different heights, greatly improving the adaptability of the measuring device.

[0036] Preferably, please refer to Figure 1 , 5 As shown in Figure 6, the rail inclination measuring device also includes a magnetic suction component 5. An installation groove 111 is provided on the base plate 11. The installation groove 111 is used to fix and limit the magnetic suction component 5. The magnetic suction component 5 is used to magnetically limit the rail to be measured placed on the base plate 11.

[0037] Understandably, since the base plate 11 supports the rail under test, in order to improve the support stability of the rail under test and achieve a certain limiting effect, and to ensure the measurement stability when the sliding contact module 4 abuts against the inclined surface under test, a magnetic suction element 5 is set on the base plate 11. The rail under test can be attracted and limited by the magnetic suction element 5, which improves the stability of the rail under test and is conducive to improving the measurement accuracy. Moreover, there is no need for additional operations to clamp and limit the rail under test; the rail under test can be directly picked up and put down, making the operation very simple and quick, and improving the overall measurement efficiency.

[0038] Optionally, the magnetic component 5 can be a commercially available magnet block, which is easy to purchase and replace, thus reducing manufacturing costs.

[0039] Preferably, please refer to Figure 1 As shown, multiple mounting slots 111 are spaced apart.

[0040] Understandably, by arranging multiple magnetic suction components 5 at intervals, the range of magnetic adsorption and limiting can be widened to accommodate the magnetic suction and limiting requirements of rails of different sizes. The interval arrangement of the multiple magnetic suction components 5 ensures that the isolation portions between them do not generate magnetic attraction, facilitating manual removal and placement of the rails from the base plate 11 or fine-tuning of their position. This also allows for easy alignment of the inclined surface to the sliding contact module 4, ensuring measurement accuracy. Furthermore, the overall measurement and adjustment operation is very convenient and intuitive, making measurement more efficient and convenient.

[0041] Preferably, please refer to Figure 1 , 2 As shown in Figure 4, the rail inclination measuring device also includes a second locking member 7. A second locking screw hole is provided on the side wall of the limiting hole 32. The second locking member 7 is used to pass through the second locking screw hole and press against the sliding abutment module 4 to lock and limit the sliding abutment module 4 and the angle ruler 3.

[0042] Understandably, the sliding abutment module 4 can slide within the limiting hole 32, thereby facilitating the adjustment of the position of the sliding abutment module 4 to abut against the inclined surface to be measured on the rail. After the sliding abutment module 4 contacts the inclined surface to be measured, the second locking piece 7 can be tightened to limit the sliding abutment module 4, so that the sliding abutment module 4 is in a limited and fixed state, which facilitates rotation measurement through the angle ruler 3 and reading the angle readings on the angle ruler 3 and the adjusting piece 2.

[0043] Optionally, the second locking element 7 is a bolt or screw. Using standard parts helps to reduce procurement and replacement costs, and the second locking element 7 can be easily turned with conventional tools, thereby facilitating the locking or releasing of the sliding contact module 4.

[0044] In some embodiments, the second locking member 7 includes a screw, the top of which is provided with a gripping platform, and the gripping platform is provided with anti-slip grooves around its perimeter, so that the second locking member 7 can be manually turned through the gripping platform to quickly achieve locking or unlocking of the sliding abutment module 4, which is beneficial to improving the convenience of operation.

[0045] Preferably, please refer to Figure 1 , 5 As shown in Figure 6, the sliding contact module 4 includes a sliding member 41 and a contact member 42. The contact member 42 and the sliding member 41 are connected perpendicularly to each other. The sliding member 41 is used to slide within the limiting hole 32, and the contact member 42 is used to abut against the inclined surface of the rail to be measured.

[0046] It is understandable that the sliding contact module 4 slides within the limiting hole 32 via the sliding member 41. The sliding member 41 can drive the contact member 42 to move axially along the limiting hole 32, and the contact member 42 abuts against the inclined surface to be measured on the rail. In conjunction with the angle ruler 3 and the adjusting member 2, the inclination is measured. The contact member 42 can increase the contact area with the surface to be measured on the rail. By tightly fitting the contact member 42 against the inclined surface to be measured on the rail, the angle ruler 3 and the adjusting member 2 can effectively ensure the measurement accuracy of the inclination of the inclined surface.

[0047] Optionally, both the sliding member 41 and the abutment member 42 are plate-shaped structures. The abutment member 42 is vertically disposed at one end of the sliding member 41, and the sliding member 41 and the abutment member 42 are integrally formed, so that the sliding abutment module 4 itself has good strength and stability.

[0048] Preferably, please refer to Figure 4 As shown, a connecting part 21 is provided around the outer periphery of the side wall of the adjusting part 2, and a locking groove 22 is provided around the inner wall of the connecting part 21. A locking part 31 is provided around the outer periphery of the angle ruler 3, and the locking part 31 is rotatably locked into the locking groove 22.

[0049] It is understandable that the connecting part 21 is a ring-shaped boss structure, and the snap-fit ​​groove 22 is opened on the inner wall of the connecting part 21. The angle ruler 3 is slidably snapped into the adjusting part 2 through the snap-fit ​​part 31 and the snap-fit ​​groove 22, so that the angle ruler 3 is nested on the adjusting part 2 and can be rotated. This helps to ensure the rotational stability of the angle ruler 3, thereby ensuring the accuracy of angle measurement.

[0050] Preferably, please refer to Figure 1 and 4 As shown, angle scales are provided on the side wall of the connecting part 21 and the angle ruler 3 on the same side.

[0051] It is understandable that the angle scale on the side wall of the adjusting component 2 is set on the side wall of the connecting part 21 on the same side as the angle ruler 3. This can prevent the angle ruler 3 from blocking the angle scale on the adjusting component 2, and make it convenient that the angle scale on the side wall of the angle ruler 3 is not too far from the angle scale on the connecting part 21, so as to make it easy to make a direct comparison reading after rotating the angle ruler 3, and thus quickly obtain the rotation angle range and complete the measurement of the tilt.

[0052] In another embodiment, the side wall of the angle ruler 3 is provided with a rotating shaft, and the side wall of the adjusting member 2 is provided with a bearing, with the rotating shaft connected to the bearing.

[0053] It is understood that in this embodiment, the angle ruler 3 is rotatably connected to the adjusting component 2 via a rotating shaft. This conventional rotating shaft design allows for a low-cost and efficient rotatable connection, and facilitates subsequent disassembly and replacement of the angle ruler 3. In this embodiment, the diameter of the angle ruler 3 is smaller than the diameter of the adjusting component 2 to prevent the angle ruler 3 from obstructing the angle scale on the side wall of the adjusting component 2.

[0054] Preferably, please refer to Figure 1 As shown, the support column 12 is vertically disposed at the first end of the base plate 11, and the support column 12 and the base plate 11 are integrally formed.

[0055] It is understandable that by setting the support column at the first end of the base plate 11, the upper surface of the base plate 11 can have a wider area for supporting the rail to be tested, so as to meet the support needs of rails of different sizes.

[0056] The integrated design of the support column 12 and the base plate 11 ensures the overall strength of the base assembly 1, avoids the problem of easy deformation of the base assembly 1, and helps to ensure the accuracy of the overall measurement of the rail inclination.

[0057] Of course, in some other embodiments, the support column 12 and the base plate 11 are detachably connected. Specifically, the support column 12 is connected to the base plate 11 by bolts, which facilitates the disassembly and assembly of the support column 12 and the overall storage of the measuring device. It should be noted that the angle between the support column 12 and the base plate 11 is measured after the support column 12 is installed to ensure accurate vertical installation between the support column 12 and the base plate 11, thereby reducing the impact on subsequent measurements.

[0058] Preferably, please refer to Figure 1 As shown, a hanging hole 121 is provided at the top of the support column 12.

[0059] It is understandable that by opening a suspension hole 121 at the top of the support column 12, not only can the measuring device be conveniently suspended and stored, but a limiting rod can also be inserted into the suspension hole 121 to limit the adjustment component 2 and prevent the adjustment component 2 from easily slipping off the support column 12.

The examples are merely for the purpose of helping to understand the method and core ideas of this application. The above descriptions are only preferred embodiments of this application.
