Description

Technical Field

[0001] This utility model relates to the field of railway turnout detection technology, specifically a rapid measuring device for the locking amount of an externally locked turnout. Background Technology

[0002] In railway systems, the locking degree of externally locking turnouts is one of the key parameters for ensuring normal turnout operation and traffic safety. Traditional measurement methods require workers to insert measuring tools into specific positions for testing. However, externally locking turnouts have complex structures and limited operating space, making the measurement process extremely inconvenient. Furthermore, insertion-based measurements are susceptible to environmental factors and human error, leading to inaccurate readings. Moreover, each measurement is time-consuming, severely impacting the efficiency of railway maintenance work.

[0003] With railway transportation becoming increasingly busy and the requirements for timely turnout maintenance becoming more stringent, there is a need for a device that can quickly and accurately measure the locking amount of externally locked turnouts. Utility Model Content

[0004] To address the problems of existing technologies, this invention provides a rapid measurement device for the locking amount of externally locked turnouts.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution: a rapid measuring device for the locking amount of an externally locked turnout, comprising a first measuring slide rod, a second measuring slide rod, and a limiting slide block. The inner side of the limiting slide block is provided with a limiting groove, and the inner wall of the limiting groove is slidably connected to the first measuring slide rod. The bottom end of the limiting groove is fixedly connected to the second measuring slide rod by screws. The first measuring slide rod is located at the top end of the second measuring slide rod. A first measuring block is fixedly connected to one side of one end of the first measuring slide rod, and a first measuring rod is fixedly connected to the other side of the other end of the first measuring slide rod. A second measuring block is fixedly connected to one side of one end of the second measuring slide rod, and a second measuring rod is fixedly connected to the other side of the other end of the second measuring slide rod. The first measuring rod and the limiting slide block are fixedly connected by a spring. One end of the first measuring rod is fixedly connected to a support rod, which is slidably connected to the limiting slide block. The support rod is located inside the spring and limits the extension and retraction direction of the spring. The top end of the first measuring slide rod is provided with a scale line.

[0006] In this method, the device is slidably connected by the first and second measuring slide rods within the limiting groove of the limiting slide block, making the measurement process flexible and convenient. Users can easily adapt to different sizes of external locking turnouts by simply sliding the slide rods, thereby quickly completing the measurement of the locking amount;

[0007] The top of the first measuring slider has a scale, which allows the user to directly read the specific value of the locking amount after sliding the slider to the appropriate position. The scale ensures the accuracy of the measurement and avoids errors that may occur in traditional measurement methods.

[0008] The device is designed to accommodate different sizes and shapes of externally locked turnouts. The first and second measuring blocks are fixedly connected to one end of the first and second measuring slides, respectively. This design allows the device to adapt to turnout locking sections of different shapes and sizes, enhancing its versatility and practicality.

[0009] The entire device has a compact structure and is easy to operate. Users can complete the measurement simply by sliding the slider and reading the scale, without the need for complicated operating procedures or professional measurement skills, which greatly reduces the difficulty of operation.

[0010] In some specific implementations, the scale lines are made of fluorescent material, making it easier for operators to clearly read the measurement values ​​at railway maintenance sites where the light is dim.

[0011] In some specific implementations, the spring is a high-strength alloy spring with good elastic recovery performance. It can stably maintain its elastic force during repeated measurement operations, so that the first measuring slide and the second measuring slide can be accurately reset. At the same time, it can withstand large tensile and compressive forces, and adapt to the measurement needs under complex working conditions.

[0012] In some specific implementations, the device is operated by measuring at one end and reading at the other end simultaneously.

[0013] The beneficial effects of this utility model are as follows:

[0014] 1. This utility model device adopts a sliding connection and spring reset design, making the measurement process smoother and faster. Operators only need to simply attach the measuring block to the turnout locking part to quickly obtain the measurement value, without complicated adjustment or calibration steps, which significantly improves measurement efficiency;

[0015] 2. The scale lines on the first measuring slide are made of fluorescent material, ensuring clear reading even in low-light conditions and avoiding measurement errors caused by poor visibility. Meanwhile, the high-strength alloy material of the spring guarantees stability during the measurement process, making the measured values ​​more accurate and reliable.

[0016] 3. The device is suitable for locking parts of externally locked turnouts of various sizes and shapes, with a wide measurement range. The elastic recovery performance of the springs enables the device to cope with measurement needs under different working conditions, such as high temperature, low temperature, and humid environments, enhancing the adaptability and durability of the device.

[0020] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of this utility model.

[0021] Example: Figures 1 to 2 The illustrated device for rapid measurement of locking amount of an externally locked turnout includes a first measuring slide rod 1, a second measuring slide rod 2, and a limiting slide block 3. A limiting groove 31 is provided on the inner side of the limiting slide block 3. The first measuring slide rod 1 is slidably connected to the inner wall of the limiting groove 31. The bottom end of the limiting groove 31 is fixedly connected to the second measuring slide rod 2 by screws. The first measuring slide rod 1 is located at the top of the second measuring slide rod 2. A first measuring block 11 is fixedly connected to one side of one end of the first measuring slide rod 1, and the other side of the other end of the first measuring slide rod 1... A first measuring rod 12 is fixedly connected. A second measuring block 21 is fixedly connected to one side of one end of the second measuring slide rod 2. A second measuring rod 22 is fixedly connected to the other side of the other end of the second measuring slide rod 2. The first measuring rod 12 is fixedly connected to the limiting slide 3 by a spring 4. A support rod 32 is fixedly connected to one end of the first measuring rod 12. The support rod 32 is slidably connected to the limiting slide 3. The support rod 32 is located inside the spring 4 and limits the extension and retraction direction of the spring 4. A scale line 13 is provided at the top of the first measuring slide rod 1.

[0022] The scale line 13 is made of fluorescent material, which makes it easy for operators to clearly read the measurement values ​​in the dim light of the railway maintenance site.

[0023] Spring 4 is a high-strength alloy spring with good elastic recovery performance. It can stably maintain its elastic force during repeated measurement operations, so that the first measuring slide 1 and the second measuring slide 2 can be accurately reset. At the same time, it can withstand large tension and pressure, and adapt to the measurement needs under complex working conditions.

[0024] The equipment is operated by measuring at one end and reading at the other end simultaneously.

[0025] In the initial state, the first measuring slide rod 1 of the rapid measuring device for the locking amount of the external lock turnout in this embodiment is located within the limiting groove 31 of the limiting slide block 3. The first measuring slide rod 1 is located at the top of the second measuring slide rod 2 and is connected to the limiting slide block 3 via the spring 4. At this time, the spring 4 is in its natural state and is not subjected to external force. The measuring blocks (11 and 21) and measuring rods (12 and 22) on the first measuring slide rod 1 and the second measuring slide rod 2 are not in contact with external objects, and the scale line 13 is clearly visible, ready for measurement operation.

[0026] Measurement operation:

[0027] During measurement, the operator first places the measuring device in the locked position of the turnout to be measured. Then, the first measuring slide rod 1 is pushed manually or mechanically to slide along the limiting slide groove 31 until the first measuring block 11 is in close contact with one side of the turnout locking mechanism.

[0028] Reading process:

[0029] After the measuring block contacts the turnout locking mechanism, the operator can measure at one end and read the value at the other, effectively avoiding the inconvenience of observation during measurement with traditional measuring equipment. The scale line 13 at the top of the first measuring slide rod 1 can be easily observed. Furthermore, because the scale line 13 is made of fluorescent material, the measured values ​​can be clearly read even in dimly lit railway maintenance sites. By reading the values ​​on the scale line 13, the locking amount of the turnout locking mechanism can be determined.

[0030] Reset and reuse:

[0031] After the measurement is completed, it automatically resets under the elastic force of spring 4. At this time, both the first measuring slide 1 and the second measuring slide 2 return to their initial state, ready for the next measurement. Because spring 4 is made of high-strength alloy spring, it has good elastic recovery performance, so it can stably maintain the elastic force during repeated measurement operations, enabling the measuring device to accurately reset.

[0032] In summary, the external locking turnout rapid measurement device of this embodiment has the advantages of simple structure, convenient operation, clear reading and accurate reset, and can meet the needs of railway maintenance site for rapid measurement of turnout locking.

[0033] 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.
