[0002] In railway construction and maintenance, track straightness is one of the key factors ensuring the safe operation of trains. Track straightness measuring instruments, as important inspection tools, directly affect the quality of track maintenance and the safety of train operation. With the continuous development of railway transportation, the requirements for track straightness measuring instruments are becoming increasingly stringent, demanding not only high-precision measurement capabilities but also convenient operation and efficient maintenance performance.
[0003] Existing track straightness measuring instruments typically consist of a measuring instrument body, sensors, and a display screen. Structurally, the measuring instrument body generally employs a relatively traditional design, such as assembling the various components together using screws or other fixing methods.
[0004] In practical track straightness measurement scenarios, existing track straightness measuring instruments have some significant problems. Firstly, regarding maintenance, existing measuring instruments often require specialized tools for disassembly when malfunctions necessitate repair. For example, when internal components of the measuring instrument malfunction, screwdrivers and other tools are needed to loosen the screws before the cover can be removed for repair. This method is not only cumbersome and time-consuming, but also, in emergency situations, the inability to find suitable tools promptly leads to prolonged repair time, affecting track inspection and maintenance. Therefore, this technology proposes a track straightness measuring instrument to address these issues. Utility Model Content
[0005] To overcome the above shortcomings, this utility model provides a track straightness measuring instrument, which aims to improve the problem that existing track straightness measuring instruments require the assistance of other tools for disassembly and repair when they malfunction, making the operation relatively cumbersome.
[0006] To achieve the above objectives, this utility model provides the following technical solution: a track straightness measuring instrument, comprising a measuring instrument body and two positioning components, wherein the positioning components are disposed on the outside of the measuring instrument body, a handle is fixedly connected to the top of the measuring instrument body, a cover plate is disposed on the inside of the measuring instrument body, and a disassembly and assembly component is disposed inside the measuring instrument body, the disassembly and assembly component being used for quick disassembly of the cover plate;
[0007] The disassembly and assembly assembly includes two locking rods and two inserts. The two inserts are fixedly connected to the outer sides of the cover plate, and the two locking rods are slidably connected to the inside of the measuring instrument body. Two slots are opened on the outer side of the measuring instrument body. An L-shaped lever is fixedly connected to the outer side of the locking rod. A spring is sleeved on the outer side of the locking rod. Two pull rings are fixedly connected to the outer side of the cover plate.
[0008] Furthermore, the outer side of the insert block is slidably connected to the inner side of the slot, and the outer side of the locking rod is slidably connected to the inner side of the locking hole.
[0009] Furthermore, one end of the spring is fixedly connected to the inner wall of the cavity of the measuring instrument body, and the other end of the spring is fixedly connected to the outer side of the locking rod.
[0010] Furthermore, the positioning component includes two mounting bases and two clamping blocks, with the two mounting bases being detachably connected to the outer sides of the measuring instrument body.
[0011] Furthermore, a guide post is fixedly connected to the outer side of the mounting base, and a slider is slidably connected to the outer side of the guide post.
[0012] Furthermore, an L-shaped plate is fixedly connected to the outer side of the slider, and one end of the L-shaped plate is fixedly connected to the outer side of the clamping block.
[0013] Furthermore, a second spring is sleeved on the outside of the guide post, and the two ends of the second spring are fixedly connected to one end of the guide post and the outside of the slider, respectively.
[0014] This utility model has the following beneficial effects:
[0015] 1. In this utility model, when the measuring instrument body malfunctions and needs to be repaired, the staff pushes the L-shaped lever to move the locking rod upward, releasing the restriction on the insertion block, and then pulls the pull ring to remove the cover plate.

[0024] 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.
[0025] Reference Figures 1-4This utility model provides an embodiment of a track straightness measuring instrument, comprising a measuring instrument body 1 and two positioning components. The positioning components are located on the outside of the measuring instrument body 1. The measuring instrument body 1, as the core component of the entire measuring instrument, is typically made of robust and durable materials, possessing high precision and stability. It can accurately measure the straightness of the track, providing crucial data support for track maintenance and repair. A handle 2 is fixedly connected to the top of the measuring instrument body 1. The handle 2 is typically made of metal or plastic, possessing a certain strength and comfort. The design of the handle 2 facilitates the operator's carrying of the measuring instrument body 1 to the vicinity of the track to be inspected. During carrying, the operator can easily grip the handle 2, preventing the measuring instrument body 1 from slipping or colliding, ensuring the safety of the measuring instrument. A cover plate 3 is provided on the inner side of the measuring instrument body 1. The cover plate 3 is typically made of metal or plastic, possessing a certain strength and sealing performance. The cover plate 3 protects the internal components of the measuring instrument body 1 from external environmental influences, such as dust and moisture. A disassembly assembly is provided inside the measuring instrument body 1 for quick disassembly of the cover plate 3. The assembly / disassembly system includes two locking rods 8 and two insert blocks 5. The two insert blocks 5 are fixedly connected to the outer sides of the cover plate 3. The insert blocks 5 are typically made of metal, providing high strength and stability. The two locking rods 8 are slidably connected inside the measuring instrument body 1. The locking rods 8 are typically made of metal, providing high strength and wear resistance. Two slots 7 are provided on the outer side of the measuring instrument body 1. The slots 7 provide space for the insertion of the insert blocks 5. An L-shaped lever 9 is fixedly connected to the outer side of the locking rods 8. The L-shaped lever 9 is typically made of metal or plastic, providing a certain degree of strength and stability. The design of the L-shaped lever 9 facilitates the operator's operation of the locking rods 8, allowing them to be easily moved upwards when the cover plate 3 needs to be removed. A spring 10 is fitted around the outer side of the locking rods 8. The spring 10 is elastic and can extend and retract within a certain range. One end of the spring 10 is fixedly connected to the inner wall of the cavity of the measuring instrument body 1, and the other end of the spring 10 is fixedly connected to the outer side of the locking rods 8. The function of spring 10 is to provide a certain elastic force to the locking rod 8, allowing it to be tightly inserted into the locking hole 6 of the insert block 5, ensuring the fixation of the cover plate 3. Two pull rings 4 are fixedly connected to the outer side of the cover plate 3. The pull rings 4 are typically made of metal or plastic, possessing a certain strength and stability. The design of the pull rings 4 allows workers to easily pull the cover plate 3 when removing it, enabling it to be easily removed from the inside of the measuring instrument body 1. The outer side of the insert block 5 is slidably connected to the inner side of the slot 7, and the outer side of the locking rod 8 is slidably connected to the inner side of the locking hole 6, ensuring that the cover plate 3 can be stably installed inside the measuring instrument body 1.
[0026] Specifically, when the measuring instrument body 1 malfunctions and requires repair, a convenient disassembly method can be adopted. The operator can simultaneously push both L-shaped levers 9 upwards. The L-shaped levers 9 are designed for easy operation; the operator can easily push the levers with their fingers without using any other complex tools. When the L-shaped levers 9 are pushed upwards, the locking rod 8 will move upwards. The locking rod 8 has a clever design that works in conjunction with the insert 5 and the locking hole 6. Moving the locking rod 8 releases the restriction on the insert 5. When one end of the locking rod 8 is completely pulled out of the locking hole 6, the restriction on the insert 5 is released. At this point, the operator can pull the two pull rings 4 to remove the cover plate 3 from the inside of the measuring instrument body 1. The pull rings 4 are designed to facilitate the operator's application of force, making the removal of the cover plate 3 easier. This installation method has significant advantages over traditional screw fastening. It eliminates the need for other tools during disassembly, making the operation more convenient. Traditional screw fastening requires the use of screwdrivers and other tools for disassembly, which is cumbersome and time-consuming. Furthermore, in confined spaces or emergency situations, disassembly using tools is not always convenient. This design, utilizing the locking rod 8, insert block 5, and pull ring 4, allows for quick removal of the cover plate 3, improving maintenance efficiency. Especially in emergency situations, it enables timely inspection and repair of the measuring instrument body 1, reducing time loss and inconvenience caused by malfunctions.
[0027] Reference Figure 1 and Figure 5 The positioning assembly includes two mounting bases 11 and two clamping blocks 16. The two mounting bases 11 are detachably connected to the outer sides of the measuring instrument body 1. The mounting bases 11 are typically made of metal, providing high strength and stability. Guide posts 12 are fixedly connected to the outer sides of the mounting bases 11. Guide posts 12 are typically made of metal, providing high strength and wear resistance. A slider 14 is slidably connected to the outer side of the guide posts 12. Slider 14 is typically made of metal or plastic, providing high strength and wear resistance. An L-shaped plate 15 is fixedly connected to the outer side of the slider 14. L-shaped plate 15 is typically made of metal, providing high strength and stability. One end of the L-shaped plate 15 is fixedly connected to the outer side of the clamping block 16. Clamping blocks 16 are typically made of metal, providing high strength and wear resistance. The clamping block 16 is designed to tightly clamp the outer side of the rail, ensuring the measuring instrument body 1 remains stable during measurement. A second spring 13 is fitted around the outer side of the guide posts 12. The second spring 13 is elastic and can extend and retract within a certain range. The two ends of spring 13 are fixedly connected to one end of guide post 12 and the outside of slider 14, respectively. The function of spring 13 is to provide a certain elastic force to slider 14, so that clamp 16 can tightly clamp the outside of rail, ensuring that the measuring instrument body 1 remains stable during the measurement process.
[0028] Specifically, in the track straightness measurement work, the staff uses handle 2 to carry the measuring instrument body 1 to the vicinity of the rail to be inspected. The handle 2 is designed very ergonomically, not only making it easy for the staff to grip, but also having sufficient strength and stability to ensure that the measuring instrument body 1 will not be accidentally dropped during transport. After arriving at the inspection location, the measuring instrument body 1 is placed on the rail. At this time, it is necessary to adjust the positioning components, moving the clamping blocks 16 on the two positioning components in opposite directions. The purpose of this is to allow the clamping blocks 16 to be smoothly placed on both sides of the rail, preparing for the subsequent clamping operation. During the movement of the clamping blocks 16, the staff can operate easily because the connection design between the clamping blocks 16 and components such as the slider 14 and the L-shaped plate 15 is reasonable, making the movement of the clamping blocks 16 smooth and unobstructed. Then, under the elastic force of the second spring 13, the slider 14 drives the L-shaped plate 15 to quickly return to its original position. The second spring 13 has good elasticity and stability, and can quickly provide restoring force after the clamping blocks 16 move, allowing the slider 14 to quickly drive the L-shaped plate 15 back to its initial position. This rapid reset design is crucial because it ensures that the clamping blocks 16 grip the outer side of the rail in the shortest possible time, improving work efficiency. When the two sets of clamping blocks 16 grip the outer side of the rail, the measuring instrument body 1 remains stable. The clamping force of the clamping blocks 16 is moderate, firmly gripping the rail without damaging it. Maintaining the stability of the measuring instrument body 1 is essential for subsequent sensor detection. Sensors need a stable environment to accurately measure the straightness of the track. If the measuring instrument body 1 is unstable, the sensor's measurement results will be affected, leading to inaccurate results. Therefore, the clamping action of the positioning components provides a stable working environment for the sensors, ensuring the accuracy and reliability of the measurement results.
[0029] Working principle: First, the operator carries the measuring instrument body 1 to the vicinity of the rail to be inspected by holding the handle 2, places the measuring instrument body 1 on the rail, and moves the clamping blocks 16 on the two positioning components in the opposite direction. Then, under the elastic force of the second spring 13, the slider 14 drives the L-shaped plate 15 to quickly reset, so that the two sets of clamping blocks 16 clamp the outer side of the rail, keeping the measuring instrument body 1 in a stable state, which is convenient for the sensors on the measuring instrument body 1 to perform subsequent detection.
[0030] In addition, when the measuring instrument body 1 malfunctions and needs to be repaired, the two L-shaped levers 9 can be pushed upwards simultaneously, thereby moving the locking rod 8 upwards. When one end of the locking rod 8 is completely pulled out from the inside of the locking hole 6, the restriction on the insert block 5 is released. Then, the two pull rings 4 can be pulled to remove the cover plate 3 from the inside of the measuring instrument body 1. Compared with the traditional screw fastening, this installation method saves the need for other tools during disassembly and is more convenient to operate.
[0031] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
