Technical Field
[0001] This utility model relates to the field of measurement technology, specifically to a railway-specific height parameter measuring device. Background Technology
[0002] In industrial production and scientific research, accurate height measurement is crucial for ensuring product quality and experimental precision. Existing height measuring devices have limitations in terms of measurement accuracy, ease of operation, and adaptability. Therefore, designing a dedicated height measuring device that is easy to operate, highly accurate, and capable of automated measurement is essential.
[0003] Traditional height measurement devices mainly employ leveling and steel tape transfer, which suffers from low measurement accuracy, untimely data acquisition, and complex manual operation. To address these issues, Gong Changliang et al. proposed a height measurement device CN221484510U, capable of high-precision measurement; Chen Chong et al. proposed an automatic height measurement system CN114383518B, enabling automated measurement of customized packages. However, these height measurement devices all suffer from low measurement accuracy, cumbersome operation, and inability to achieve automated measurement. Summary of the Invention
[0004] The purpose of this utility model is to address the shortcomings of the existing technology by providing a railway-specific height parameter measuring device. Through the structural design of the height measuring instrument and the adjustment platform, it solves the problems of existing ultra-high reproducibility value parameter measuring devices and methods for railway gauge calibrators and track inspection instrument calibration platforms, such as complex operation, low measurement accuracy, and inability to achieve automatic measurement.
[0005] The objective of this utility model is achieved through the following technical solution:

[0007] The height measuring instrument includes a base with a positioning groove. A positioning key is provided on the fine-tuning platform. The positioning key matches the positioning groove. The height measuring instrument and the fine-tuning platform are connected by the cooperation between the positioning groove and the positioning key to form a limiting connection.
[0008] The height measuring instrument includes a controller, a grating sensor, a display device, and a probe. The grating sensor is connected to control the probe, and the controller is connected to the display device, the grating sensor, and the probe.

[0014] Figure 3 This is a three-dimensional structural diagram of the present invention. Detailed Implementation
[0015] The features and other related features of this utility model will be further described in detail below with reference to the accompanying drawings and embodiments, so as to facilitate the understanding of those skilled in the art:
[0016] like Figure 1-3 As shown in the figure, numbers 1-12 represent: positioning groove 1, fine adjustment knob 2, pre-positioning platform 3, column 4, adjustable support leg 5, pre-positioning platform 6, fine adjustment platform 7, base 8, probe 9, display device 10, controller 11, and level adjustment component 12.
[0017] Example: Figures 1 to 3 As shown, the railway-specific height parameter measuring device in this embodiment includes two parts: a height measuring instrument and an adjustment platform. The two are relatively independent and can be assembled into a complete device to measure the railway-specific height.
[0018] Specifically, in this embodiment, the height measuring instrument is mounted on the adjustment platform. The height measuring instrument is used to measure height, while the adjustment platform is mainly used to adjust the position of the height measuring instrument, especially its horizontal position.
[0019] The adjustment platform includes a pre-positioning platform 3 and a pre-positioning platform 6 arranged vertically, with the pre-positioning platform 3 positioned above the pre-positioning platform 6. Three adjustable legs 5 are located at the bottom of the pre-positioning platform 6, arranged in a triangular formation to ensure stable support for the pre-positioning platform 6. The level of the pre-positioning platform 6 can be adjusted by adjusting each adjustable leg 5. The pre-positioning platform 3 is fixed above the supporting platform 6 by four columns 4; when the pre-positioning platform 6 is leveled, the pre-positioning platform 3 is also adjusted to a level position.
[0020] The adjustment platform also includes a fine-tuning platform 7 and a leveling component. The fine-tuning platform 7 is positioned above the prepositioning platform 6, and the leveling component is positioned between the prepositioning platform 6 and the fine-tuning platform 7. The leveling component is used to further adjust the levelness of the fine-tuning platform 7, thereby forming a secondary adjustment mechanism with the adjustable support 5 to ensure the levelness of the altimeter.
[0021] The leveling component can employ various types of push-adjustment mechanisms that can be installed below the fine-tuning platform 7, leveling the platform by pushing its bottom surface. In this embodiment, the leveling component includes a fine-tuning knob 2, a screw, a linear guide rail, a movable linkage assembly, a slide, and a support base. The fine-tuning knob 2 is connected to the screw, the slide is mounted on the linear guide rail, and the screw's rotation causes the slide to slide along the linear guide rail. The movable linkage assembly is mounted on the slide and located below the fine-tuning platform 7, and the support base supports the screw.
[0022] The height measuring instrument includes a base 8, a probe 9, a display device 10, a controller 11, and a grating sensor. The base 8 has a positioning groove 1, and the fine-tuning platform 7 has a positioning key. The connection between the positioning groove 1 and the positioning key allows the base 8 to be positioned on the fine-tuning platform 7. A limit block is located on one side of the fine-tuning platform 7 to limit the installation position of the height measuring instrument. The grating sensor is connected to the controller 11, the display device 10, and an external power supply on one side, and to the probe 9 on the other side. The base 8 serves as the bottom platform for the grating sensor.
[0023] When using this embodiment, the following steps are included:
[0024] 1) Position the adjustment platform in a horizontal position, adjust the height of the three adjustable feet 5 through the pre-positioning platform 6, and then use the fine adjustment knob 2 of the fine adjustment platform 7 to move the slide and movable linkage assembly on the linear guide rail by the screw to finely adjust the level of the platform 7.
[0025] 2) After adjusting the platform (fine-tuning platform 7) to a horizontal position, connect the positioning slot 1 below the height measuring instrument to the positioning key on the adjustment platform, turn on the external power supply, operate the control interface of the controller 11, so that the probe 9 is aligned with one end of the object being measured, and record a value a. Then, through the operation interface, move the probe 9 to the other end of the object being measured and record a value b. The absolute value of the difference between the two values is the height of the object being measured. Finally, the absolute values of a, b, and ab are all displayed on the display device 10. This is a manual measurement.
[0026] 3) After adjusting the platform to a horizontal position, connect the positioning slot 1 below the height measuring instrument to the positioning key on the adjustment platform, turn on the external power supply, operate the controller interface, click on the automatic measurement in the controller interface, place the object to be measured, and the probe will automatically move to both ends of the object to be measured. Finally, the three values will be displayed on the display device 10 as in step two. This is automatic measurement.
[0027] The railway-specific height parameter measuring device in this embodiment can be coarsely adjusted using adjustable feet and finely adjusted using a fine-tuning knob. Combining the two maximizes the levelness of the adjustment platform. The height measuring instrument can achieve both automatic and manual measurement modes, making operation more convenient.
[0028] Although the above embodiments have described the concept and embodiments of the present invention in detail with reference to the accompanying drawings, those skilled in the art will recognize that various improvements and modifications can still be made to the present invention without departing from the scope of the claims, and therefore will not be elaborated here.
