Description

Technical Field

[0001] This utility model belongs to the field of railway engineering technology, and in particular relates to a vernier caliper for measuring the gap depth of high-speed railway track slabs. Background Technology

[0002] In the construction and operation of high-speed railways, ballastless track in tunnels, as an important type of track structure, is widely used in various high-speed railway lines due to its advantages such as high stability, high smoothness and low maintenance, providing a solid guarantee for the safe and high-speed operation of trains. However, with the increase in the operating time of high-speed railways and the repeated action of train loads, some defects inevitably occur in ballastless track in tunnels. Among them, the separation between the track slab and the backfill layer of the invert arch is a relatively common and significant defect.

[0003] Therefore, it is necessary to treat the joint defects between the track slab and the backfill layer of the invert. During the treatment, measuring the joint depth is a key step. Only by mastering the specific depth information of the joint can the severity of the defect be accurately assessed, thereby formulating a scientific and reasonable maintenance plan. However, there is currently a lack of tools on the market specifically for measuring the joint depth of high-speed railway track slabs. The traditional measurement method is to insert a steel bar into the joint between the track slab and the backfill layer of the invert, and then mark it on the steel plate. After marking, the steel plate is removed, and a measuring tape is used to measure the marked area to obtain the specific depth information of the joint. This process requires multiple operations such as inserting the steel bar, marking, removing it, and measuring with a measuring tape, which is cumbersome and inefficient. Summary of the Invention

[0004] The purpose of this invention is to address the problems existing in the prior art by providing a vernier caliper for measuring the gap depth of high-speed railway track slabs.

[0005] To achieve the above objectives, the utility model employs the following technical solution: a vernier caliper for measuring the gap depth of high-speed railway track slabs, comprising a caliper base, a mounting groove formed on the surface of the caliper base, a measuring caliper installed in the mounting groove, an end cap mounted at one end of the caliper base, an anti-disengagement sleeve mounted at the other end of the caliper base, a mounting seat provided in the mounting groove, a sliding element provided between the mounting seat and the mounting groove, and an insertion caliper for use with the measuring caliper mounted on the side of the mounting seat near the measuring caliper.

[0006] By adopting the above technical solution and setting up structures such as a ruler base, measuring ruler, mounting base, insertion ruler, and sliding parts, the depth of the gap can be measured quickly and accurately. Compared with the traditional method, the insertion ruler of this vernier caliper can be directly inserted into the gap, and the measuring ruler can accurately read the gap depth. This avoids the cumbersome operation of multiple insertions, markings, extractions, and measurements in the traditional method, greatly improving the measurement efficiency and providing a powerful tool for the rapid diagnosis and repair of track defects in high-speed railways.

[0007] Optionally, the length of the ruler base is 100cm-130cm, the width of the ruler base is 3cm-5cm, and the thickness of the ruler base is 2cm-4cm.

[0008] By adopting the above technical solution, the size design of the ruler holder ensures that the measuring ruler has sufficient installation space, while also avoiding the situation where it is too short to measure and too long to be convenient to operate and place in a limited space.

[0009] Optionally, an adhesive layer is provided between the measuring ruler and the mounting groove.

[0010] By adopting the above technical solution, the adhesive layer enhances the connection stability between the measuring scale and the scale base, preventing the measuring scale from loosening or falling off due to external forces during use, and ensuring the continuity and reliability of the measurement process.

[0011] Optionally, the end cap seat is provided with a plug-in seat, and one end of the ruler seat is provided with a plug-in groove that is adapted to the plug-in seat.

[0012] By adopting the above technical solution, this claim provides a plug-in seat on the end cap seat and opens a matching plug-in slot at one end of the ruler seat. The design of the plug-in seat on the end cap seat and the plug-in slot on the ruler seat realizes a quick and stable connection between the end cap seat and the ruler seat. This plug-in structure not only facilitates the installation and disassembly of the end cap seat and improves the assembly and maintenance efficiency of the tool, but also prevents the mounting seat from detaching from the ruler seat.

[0013] Optionally, the anti-slip sleeve is a concave sleeve, and there is a gap difference between the concave part of the anti-slip sleeve and the mounting groove, and the gap difference is 0.3cm-0.5cm.

[0014] By adopting the above technical solution and the anti-detachment design, the mounting base and the ruler base can be prevented from separating. At the same time, the design of the spacing difference allows the inserted ruler to extend out and also prevents the insertion end of the inserted ruler from tilting up.

[0015] Optionally, the mounting base is T-shaped, and a connecting groove for mounting the insertion ruler is provided at one end of the mounting base near the ruler base. A push handle is provided on the outer side of the mounting base.

[0016] By adopting the above technical solution, the T-shaped mounting base structure can better cooperate with the sliding parts, ensuring the stable insertion of the insert ruler and the accurate reading of the measuring ruler. The design of the connecting groove allows the insert ruler to be firmly installed on the mounting base, ensuring the stability of the insert ruler during the measurement process. The push handle provides the operator with a convenient operating point, making the insertion and removal of the insert ruler more labor-saving and convenient, and further improving the measurement efficiency.

[0017] Optionally, the sliding member includes guide rods mounted on the side walls of the mounting groove, and the outer side of the mounting base is provided with guide grooves adapted to the guide rods.

[0018] By adopting the above technical solution, the design of the sliding component allows the mounting base to slide linearly within the ruler base, avoiding any tilting or jamming of the mounting base during the sliding process, thus ensuring that the insertion ruler can be smoothly inserted into the gap.

[0019] Optionally, the lengths of the insertion ruler and the measuring ruler are 90cm-120cm, and the thicknesses of the insertion ruler and the measuring ruler are 0.1cm-0.2cm, respectively.

[0020] By adopting the above technical solution, the size design of the insertion ruler and the measuring ruler enables the insertion ruler to adapt to the measurement needs of gaps at different depths. At the same time, the thin thickness ensures that the insertion ruler can be smoothly inserted into narrow gaps, thus improving the applicability of the tool.

[0021] Compared with the prior art, the beneficial effects of this utility model are:

[0022] 1. The vernier caliper, with its structure including a caliper base, measuring scale, mounting base, insertion scale, and sliding parts, allows the insertion scale to be directly inserted into the gap, and the measuring scale to accurately read the gap depth. This avoids the need for multiple operations such as inserting, marking, removing, and measuring with a tape measure required by traditional measurement methods, greatly improving measurement efficiency and providing a powerful tool for the rapid diagnosis and repair of track defects in high-speed railways.

[0023] 2. The design of the guide rod and guide groove ensures that the mounting base slides linearly within the ruler base, avoiding tilting or jamming of the mounting base during sliding, thus ensuring accurate readings of the measuring ruler and improving measurement accuracy.

[0024] 3. The design of the plug-in seat on the end cap and the plug-in slot on the ruler seat enables a quick and stable connection between the end cap and the ruler seat. This plug-in structure not only facilitates the installation and disassembly of the end cap, but also improves the efficiency of tool assembly and maintenance. Attached Figure Description

[0031] The technical solution of this utility model will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0032] In the description of this utility model, it should be noted that the terms "middle", "upper", "lower", "left", "right", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0033] like Figure 1 As shown in Figure 5, the specific solution of the embodiment is as follows: A vernier caliper for measuring the gap depth of high-speed railway track slabs includes a caliper base 1. The length of the caliper base 1 is 100cm-130cm, the width of the caliper base 1 is 3cm-5cm, and the thickness of the caliper base 1 is 2cm-4cm. The caliper base 1 serves as the main support structure of the entire vernier caliper, providing an installation base for other components. The size design of the caliper base 1 provides sufficient installation space for the measuring ruler 3, ensuring that the measuring ruler 3 can be installed stably, and can also adapt to the relatively narrow and space-limited working environment in high-speed railway tunnels, avoiding the inconvenience of operation and placement due to the caliper base 1 being too long, or the inability to meet measurement requirements due to it being too short.

[0034] The surface of the ruler base 1 is provided with an installation groove 2, and a measuring ruler 3 is installed in the installation groove 2. An adhesive layer is provided between the measuring ruler 3 and the installation groove 2. The adhesive layer enhances the connection strength between the two and effectively prevents the measuring ruler 3 from loosening or falling off due to external forces during use, ensuring the continuity of the measurement process and the accuracy of the measurement results. The adhesive layer is epoxy resin or polyurethane adhesive, etc. The measuring ruler 3 is fixed to the bottom wall of the installation groove 2 by applying it. During use, the measuring ruler 3 can be used to accurately read the depth value of the gap between the track bed slab and the backfill layer of the invert arch.

[0035] One end of the ruler base 1 is equipped with an end cap 4, and the end cap 4 is provided with a plug-in seat 41. One end of the ruler base 1 is provided with a plug-in groove 42 that is adapted to the plug-in seat 41. The ruler base 1 is provided with a fastening bolt that passes through and extends into the plug-in groove 42. One end of the fastening bolt abuts against the plug-in seat 41. The insertion of the plug-in seat 41 into the plug-in groove 42 allows the end cap 4 to be easily disassembled and assembled, and can also effectively prevent the mounting base 6 from separating from the ruler base 1 during the measurement process, ensuring the smooth progress of the measurement.

[0036] The other end of the ruler base 1 is equipped with an anti-disengagement sleeve 5. The anti-disengagement sleeve 5 is a concave sleeve. There is a gap difference between the recessed part of the anti-disengagement sleeve 5 and the mounting groove 2, and the gap difference is 0.3cm-0.5cm. The main function of the anti-disengagement sleeve 5 is to prevent the mounting base 6 from disengaging from the ruler base 1 during the sliding process, so as to ensure that the inserted ruler 8 can be stably used for measurement. The design of its gap difference provides sufficient space for the extension of the inserted ruler 8, and at the same time, it can prevent the insertion end of the inserted ruler 8 from tilting up, so that the inserted ruler 8 can be inserted in a horizontal state.

[0037] The mounting slot 2 is provided with a mounting base 6, which is T-shaped. The mounting base 6 has a connecting slot for the insertion ruler 8 to be installed at one end near the ruler base 1. The outer side of the mounting base 6 is provided with a push handle 61. The design of the connecting slot on the mounting base 6 allows the insertion ruler 8 to be inserted. After insertion, it can be fixed by screws. The push handle 61 on the outer side of the mounting base 6 provides a convenient operating point for the operator, making the insertion and removal of the insertion ruler 8 more effortless and convenient, and greatly improving the measurement efficiency.

[0038] A sliding element 7 is provided between the mounting base 6 and the mounting groove 2. The sliding element 7 includes guide rods 71 ​​installed on both side walls of the mounting groove 2. A guide groove 72 adapted to the guide rods 71 ​​is provided on the outer side of the mounting base 6. The design of the guide rods 71 ​​and the guide groove 72 guides the mounting base 6 to slide linearly in the mounting groove 2 within the ruler base 1, ensuring that the insert ruler 8 can be accurately inserted into the gap and measured, avoiding the mounting base 6 from being skewed or stuck. In some embodiments, the sliding element 7 can be replaced by a slider and a sliding groove. The slider is installed on both sides of the mounting base 6, and the sliding groove used in conjunction with the slider is opened on both sides of the mounting groove 2.

[0039] An insertion ruler 8, which works in conjunction with the measuring ruler 3, is installed on the side of the mounting base 6 near the measuring ruler 3. Under the push of the mounting base 6, the insertion ruler 8 is inserted into the gap between the track bed slab and the backfill layer of the invert arch. By cooperating with the measuring ruler 3, the depth of the gap is determined. The lengths of the insertion ruler 8 and the measuring ruler 3 are 90cm-120cm, and the thicknesses of the insertion ruler 8 and the measuring ruler 3 are 0.1cm-0.2cm, respectively. The relatively thin design of the insertion ruler 8 ensures that it can be smoothly inserted into the narrow gap and avoids secondary damage to the gap.

[0040] The working principle of the above embodiments is as follows:

[0041] The operator holds the push handle 61 on the outside of the mounting base 6 and applies a certain pushing force to make the mounting base 6 slide in the mounting groove 2 in the ruler base 1. During the sliding process of the mounting base 6, the guide groove 72 moves linearly along the guide rod 71, synchronously guiding the mounting base 6 to slide linearly in the mounting groove 2 in the ruler base 1, ensuring that the insertion ruler 8 can be accurately inserted into the gap and measured, avoiding the mounting base 6 from being skewed or stuck. As the mounting base 6 slides, the insertion ruler 8 installed on the side of the mounting base 6 near the measuring ruler 3 is gradually inserted into the gap between the track bed slab and the backfill layer of the invert arch. When the insertion ruler 8 is inserted to the bottom of the gap and cannot go any further, the corresponding value will be displayed on the measuring ruler 3 used in conjunction with the insertion ruler 8. The operator can directly read the value from the measuring ruler 3 to complete a gap depth measurement.

[0042] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
