Technical Field

[0001] This utility model relates to the field of railway track inspection tools, specifically a railway track spacing inspection device. Background Technology

[0002] The track gauge is one of the core parameters for ensuring the safe operation of trains, and its detection accuracy directly affects the stability and safety of railway transportation.

[0003] As a precision component that directly contacts the track gauge, the measuring head is usually exposed when not in use. During transportation or storage, accidental collisions can easily cause deformation or damage to the measuring head, resulting in a shift in the measurement reference plane and affecting the accuracy of subsequent inspections. Utility Model Content

[0004] The purpose of this invention is to provide a railway track spacing detection device to solve the problem mentioned in the background art that conventional track gauges lack protective measures for the measuring head.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a railway track spacing detection device, comprising a ruler, a digital display device, a track mounting base, and a probe. A protective cover is rotatably mounted on the side wall of the track mounting base via a rotating shaft. An elastic member is connected between the protective cover and the track mounting base so that the protective cover can rotate around the shaft via the elastic member to abut against the track mounting base and be positioned around the probe.

[0006] Preferably, the elastic member is a tension spring movably installed on the side wall of the rail seat, the side of the protective cover is integrally formed with a connecting section, a screw is fixedly installed on the connecting section, and the other end of the tension spring is hooked on the screw.

[0007] Preferably, the main body of the protective cover has a U-shaped structure.

[0008] Preferably, a connecting section is provided at the center of the protective cover.

[0009] Preferably, the width of the protective cover is adapted to the probe.

[0010] Preferably, the corners of the protective cover are rounded for a smooth transition.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] This utility model uses a tension spring and a protective cover to form a protective component for the measuring head at the end of the rail base. During transportation or storage, the protective cover can buffer accidental collisions and prevent the measuring head from being deformed or damaged by external impacts, ensuring measurement accuracy and maintaining the performance stability of the track gauge. This ensures the efficiency and safety of railway track inspection work. The structure is simple, the operation is convenient, and the investment cost is effectively reduced.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Please see Figures 1-4This utility model provides a technical solution: a railway track spacing detection device, including a ruler 1, a digital display device 2, a track mounting base 3, and a probe 6. All of the above are existing technologies. One side of the probe 6 is fixed, while the other side is movable. The movable probe 3 measures the distance moved by a displacement sensor. The displacement sensor converts the mechanical displacement into an electrical signal, which is then calculated by a microprocessor to determine the track gauge value. The gauge value is displayed by the digital display device 2. A protective cover 4 is rotatably mounted on the side wall of the track mounting base 3 via a rotating shaft. The width of the protective cover 4 is adapted to the probe 6. The main body of the protective cover 4 has a U-shaped structure, with a connecting section 7 at its center. The corners of the protective cover 4 are rounded for a smooth transition, preventing sharp edges from scratching the skin. An elastic member connects the protective cover 4 and the track mounting base 3, allowing the protective cover 4 to rotate around the shaft until it contacts the track mounting base 3 and is positioned around the probe 6 to form a protective screen. The protective cover 4 has an elastic component, a tension spring 5 movably mounted on the side wall of the rail base 3, and a connecting section 7 integrally formed on the side of the protective cover 4. A screw 8 is fixedly mounted on the connecting section 7, and the other end of the tension spring 5 is hooked onto the screw 8. The movably mounted tension spring 5 facilitates the limiting of the protective cover 4. After the track distance measurement is completed, the protective cover 4 is flipped until the top support surface of its connecting section 7 contacts the bottom surface of the rail base 3. At this time, the protective cover 4 is positioned outside the measuring head 6, forming a protective space. During distance measurement, the protective cover 4 is rotated in the opposite direction to the top surface of the rail base 3 to move the protective cover 4 away from the measuring head 6. This application uses the tension spring 5 and the protective cover 4 in cooperation at the end of the rail base 3 to form a protective component for the measuring head 6. During transportation or storage, the protective cover 4 can buffer accidental collisions and prevent the measuring head 6 from being deformed or damaged by external impact, ensuring measurement accuracy, thereby maintaining the performance stability of the track gauge, ensuring the efficiency and safety of railway track inspection work, and having a simple structure and convenient operation, effectively reducing investment costs.
