Description

Technical Field

[0001] This utility model relates to a railway construction clearance measuring instrument, belonging to the technical field of railway construction measuring instruments. Background Technology

[0002] An existing technology, such as the one disclosed in application number 202120261685.0, discloses a platform clearance measuring instrument that facilitates positioning and measurement. It includes a fixed frame and a plug block. A fixed block is fixed to one side of the fixed frame, and a threaded rod is connected to one side of the fixed block. A pressing block is connected to the bottom end of the threaded rod, and a magnet is connected to one side of the pressing block. A fixed rod is fixed to the top of the fixed frame, and a connecting groove is provided inside the fixed rod. This platform clearance measuring instrument, which facilitates positioning and measurement, is equipped with a pressing block and a magnet. When the threaded rod is rotated, it slides through the fixed block and rotates along the pressing block. At this time, the threaded rod pushes the pressing block and the magnet downwards. When the pressing block and the magnet move to the appropriate position, the pressing block presses against the track, and the magnet attracts to the track. The special material of the pressing block can block the magnetic attraction of the magnet from left to right, facilitating the positioning of the fixed frame and preventing it from causing the machine body to move arbitrarily.

[0003] The above-mentioned applications still have shortcomings:

[0004] This type of equipment uses magnetic attraction to fix it to the track, and the height of the detection equipment and the fixed frame control mechanism is adjusted. However, it has the problems of large size, inconvenience in folding and adjusting the angle, measuring the angle, and remote data transmission.

[0005] To address these issues, a railway construction clearance measuring instrument was designed. Utility Model Content

[0006] The main purpose of this utility model is to provide a railway construction clearance measuring instrument.

[0007] The objective of this utility model can be achieved by adopting the following technical solution:

[0008] A railway construction clearance measuring instrument includes a folding bracket body, with intelligent detectors magnetically connected to both ends of the folding bracket body;

[0009] The folding joint of the main body of the folding bracket is a folding joint component;

[0010] The folding bracket body and the intelligent detector are equipped with control and transmission components, and the intelligent detector is equipped with measurement components.

[0011] Preferably, the control transmission component includes an angle sensor, a main control circuit board, a distance sensor, and a data transmission cable;

[0012] The folding bracket body is equipped with a data transmission cable, which is connected to the intelligent detectors at both ends of the folding bracket body. The intelligent detector at one end of the folding bracket body is equipped with a main control circuit board, and a distance sensor is installed on one side of the main control circuit board.

[0013] Preferably, the measuring components include a prism laser and a gyroscope, with the prism laser installed inside the intelligent detector and the gyroscope installed on the main control circuit board.

[0014] Preferably, a stepper motor is installed on one side of the gyroscope, a Wi-Fi wireless module is installed on one side of the stepper motor, and a battery is installed on the other side of the stepper motor.

[0015] Preferably, the intelligent detector is equipped with a Wi-Fi wireless module on its outside, the folding bracket body has a limit of 2064mm and a height of 5044mm, and the folding bracket body has a built-in data transmission cable.

[0016] Preferably, an angle sensor is installed at the bottom of the intelligent detector.

[0017] Preferably, a folding joint is installed at the connection and fitting point of the folding bracket body.

[0018] The beneficial technical effects of this utility model are as follows:

[0019] This utility model provides a railway construction clearance measuring instrument.

[0020] 1) Place the intelligent measuring instrument at both ends of the foldable bracket, which is placed on the rail plane. It can simultaneously measure the horizontal angle of the rail and calculate the height deviation of the rail. During use, the stepper motor is controlled by a mobile phone or remote control to project two laser beams onto the measuring point. The microcontroller reads the angle value of the two laser beams at this time. Since the rail gauge is fixed (1435mm), the height of the measuring point from the rail surface and the distance from the center of the track can be calculated by using the principle of trigonometric functions. That is, the limit value of the measuring point is realized, which can be folded and adjusted to measure and transmit the angle.

[0021] 2) Under the control of the main control circuit board, the prism laser is driven by the stepper motor 7 to accurately hit the two laser beams on the rail measurement point. The prism laser 4 can diffuse the laser beam into a uniform laser line to ensure accurate coverage of the measurement point. It can optimize the laser beam to draw a straight line with uniform optical density, good stability and straightness after passing through. The Powell prism scribing mode is better than the scribing mode of the cylindrical lens. It can eliminate the central hot spot and fading edge distribution of the Gaussian beam and improve the accuracy of measurement.

[0022] 3) By using a gyroscope-assisted angle sensor, the stability and accuracy of angle measurement under different working conditions are further improved. By sensing the attitude change of the measuring instrument in real time, the angle data is corrected and compensated, effectively reducing the measurement error caused by factors such as tilting and shaking of the measuring instrument. The angle is marked, and the angle value of the two laser beams is monitored in real time by the angle sensor and the data is transmitted to the main control circuit board. Its high-precision angle detection capability means that as the magnetic field parallel to the chip surface rotates, the chip will output the corresponding encoded angle signal with a signal delay of less than 2us. At the same time, the user can also read the angle data calculated internally by the chip through the high-speed SPI interface.

[0023] 4) The stepper motor precisely adjusts the angle and position of the Powell prism laser according to the instructions of the main control circuit board, ensuring that the laser can be accurately projected onto the designated measurement point on the rail, thus guaranteeing the accuracy of the measurement.

[0024] 5) The Wi-Fi module supports establishing a wireless connection with mobile phones or remote control terminals, allowing operators to send operation commands via mobile APP or remote control, receive measurement data in real time, realize remote monitoring and data management, and improve the convenience and flexibility of measurement work.

[0030] To enable those skilled in the art to understand the technical solution of this utility model more clearly, the present utility model will be further described in detail below with reference to the embodiments and accompanying drawings, but the implementation of this utility model is not limited thereto.

[0031] Example 1

[0032] This utility model is as follows Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, this embodiment proposes a railway construction clearance measuring instrument. Intelligent measuring instruments 3 are placed at both ends of a folding bracket 1. The folding bracket 1 is placed on the rail plane and fixed by bolts, clamps, magnetic attraction, or clips. A data transmission cable 13 is installed inside the folding bracket body 1, and the data transmission cable 13 is connected to the intelligent measuring instruments 3 at both ends of the folding bracket body 1. A main control circuit board 11 is installed inside the intelligent measuring instrument 3 at one end of the folding bracket body 1. A distance sensor 12 is installed on one side of the main control circuit board 11. The measuring components include a prism laser 4 and a gyroscope 6. The intelligent measuring instrument 3 contains a prism laser... The device 4, a prism laser 4, can generally measure up to 1900 meters, and for highly reflective targets, it can reach a range of 2500 meters. A gyroscope 6 is installed on the main control circuit board 11, and a stepper motor 7 is installed on one side of the gyroscope 6. It can simultaneously measure the horizontal angle of the rail and calculate the height deviation of the rail. During use, the stepper motor 8 is controlled by a mobile phone or remote control to hit two laser beams onto the measurement point. The microcontroller reads the angle value of the two laser beams at this time. Since the rail gauge is constant (1435mm), the height of the measurement point from the rail surface and the distance from the center of the track can be calculated by using the principle of trigonometric functions. That is, the limit value of the measurement point.

[0033] The clearance measurement of this equipment is 2064mm, and the height is 5044mm. Through on-site clearance measurement tests on high-pillar signal machines, the intelligent building clearance measuring instrument has proven to be highly practical. It is quick to assemble and disassemble, easy to carry, and simple and flexible to control with a remote control. The measurement work that previously required more than three people can now be completed by just one person. Previously, measurement data needed to be recorded, which could be lost. Now, data can be recorded in real time via a mobile APP and exported to an Excel spreadsheet, improving work efficiency. Analysis of the test data shows that the clearance measurement difference is 11mm, and the height measurement difference is 16mm. Due to the inherent large error in manual measurement, the test results are considered relatively reliable. However, the measurement accuracy still needs further verification in practice.

[0034] Example 2

[0035] like Figure 1 As shown, this railway construction clearance measuring instrument includes an intelligent measuring instrument 3 and a folding bracket body 1;

[0036] like Figure 3 and 4 As shown, the intelligent measuring instrument includes a main control circuit board 11, a prism laser 4, a Wi-Fi wireless module 8, an angle sensor 12, a stepper motor 7, a gyroscope 6, and a battery 5.

[0037] Main control circuit board 11: As the core control unit of the measuring instrument, it is responsible for coordinating the work of various components, receiving and processing data from angle sensor 8, gyroscope 6, etc., performing calculations according to preset algorithms, and controlling the operation of components such as stepper motor 7 and prism laser 4.

[0038] Prism Laser 4: Under the control of the main control circuit board and driven by the stepper motor 7, the two laser beams are precisely projected onto the rail measurement points. Prism Laser 4 can diffuse the laser beams into uniform laser lines, ensuring accurate coverage of the measurement points. It allows the laser beam to be optimally drawn into a straight line with uniform optical density, good stability, and good straightness after passing through. The Powell prism scribing mode is superior to that of cylindrical lenses. It can pass through the complex two-dimensional aspherical surface at the top. When the Gaussian laser beam passes through the Powell prism, it will generate a large amount of spherical aberration, thereby redistributing the optical path. Specifically, it reduces the light in the central area and increases the light at the edges, thus forming a straight line with uniform optical density, good stability, and good straightness. It effectively eliminates the central hot spot and fading edge phenomenon of the Gaussian beam, and eliminates the central hot spot and fading edge distribution of the Gaussian beam.

[0039] Wi-Fi module 8: A Wi-Fi module 8 is installed on one side of the stepper motor 7, and a battery 5 is installed on the other side of the stepper motor 7. It supports establishing a wireless connection with a mobile phone or remote control terminal, which makes it convenient for operators to send operation commands through a mobile APP or remote control, receive measurement data in real time, realize remote monitoring and data management, and improve the convenience and flexibility of measurement work.

[0040] Angle sensor 10: Used to monitor the angle values ​​of the two laser beams in real time and transmit the data to the main control circuit board. Its high-precision angle detection capability means that as the magnetic field parallel to the chip surface rotates, the chip will output a corresponding encoded angle signal with a signal delay of less than 2us. At the same time, users can also read the angle data calculated internally by the chip through the high-speed SPI interface.

[0041] Stepper Motor 7: According to the instructions of the main control circuit board, it precisely adjusts the angle and position of the Powell prism laser to ensure that the laser can be accurately projected onto the designated measurement point on the rail, thus guaranteeing the accuracy of the measurement.

[0042] Gyroscope 6: An auxiliary angle sensor that further improves the stability and accuracy of angle measurement under different working conditions. By sensing the attitude changes of the measuring instrument in real time, it corrects and compensates for the angle data, effectively reducing measurement errors caused by factors such as instrument tilt and shaking.

[0043] Battery 5: Provides a stable power supply for the entire intelligent measuring instrument. It adopts a high-capacity, long-lasting lithium battery to ensure that the measuring instrument can operate continuously and stably during long-term railway measurement operations. At the same time, it is equipped with a low battery alarm function to promptly remind the operator to charge or replace the battery when the power is insufficient.

[0044] Interconnection or relative position of each component: The foldable bracket unfolds with intelligent measuring instruments placed on both sides of the upper part. The bracket and the measuring instrument are connected by magnetic attraction. There is a data transmission wire 13 in the middle for data transmission. The bottom of both ends of the foldable bracket 1 has an insulating shell to prevent the track circuit from being blocked. At the same time, there is a right-angle folding joint at the bottom to ensure that the track gauge rod is perpendicular to the basic rail during measurement as much as possible.

[0045] The above description is only a further embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the scope disclosed by the present utility model, based on the technical solution and concept of the present utility model, shall fall within the protection scope of the present utility model.
