Description

Technical Field

[0001] This invention relates to the field of railway construction track gauge technology, and in particular, to a multi-purpose track gauge. Background Technology

[0002] The accuracy of traditional mechanical gauge rulers is affected and constrained by factors such as the gauge's structure, usage conditions, the user's measurement skills, and manufacturing level. Although their metrological performance at room temperature can meet the requirements of relevant standards and metrological regulations, it cannot be fully guaranteed to meet the relevant requirements under other environmental conditions.

[0003] The advent of digital track gauges has opened a new path for solving the above problems, as exemplified by patents such as CN118029211A (a track gauge for precision gauge installation and a gauge displacement method) and CN220704220U (a railway construction track gauge). However, both traditional mechanical track gauges and existing digital track gauges have the following drawbacks:

[0004] 1. Whether it is a traditional mechanical or digital display type, it is for measuring a single track gauge, such as the 600, 900, 1435 type and the measuring point under the rail head;

[0005] 2. Traditional mechanical gauges are greatly affected by environmental factors, resulting in inaccurate readings;

[0006] 3. Both have short service life and are prone to wear, which can easily cause measurement errors. Furthermore, during use, problems such as rust can reduce the accuracy of the gauge and make disassembly and assembly more difficult.

[0007] 4. The gauge ruler is only placed on the track during use. It will shift when it encounters external force, causing measurement errors.

[0008] 5. The gauge itself has a crossbeam structure, and most of the weight is concentrated in the middle of the crossbeam. Over time, deformation will occur, causing measurement errors.

[0009] 5. During measurement, a reference surface can only be measured vertically downwards from the top of the rail. When encountering a rail bottom slope, it is impossible to accurately measure the longitudinal reference surface of the rail.

[0010] 6. The existing track gauges are mainly manual, and there are human errors in the placement of the track gauges, continuous measurement, and reading. Summary of the Invention

[0011] This invention provides a multi-purpose track gauge to solve the technical problems of existing track gauges, such as limited track gauge measurement, significant environmental influence on the measurement structure, low measurement accuracy, and inability to accurately measure the spacing between rails with a bottom slope.

[0012] The technical solution adopted in this invention is as follows:

[0013] A multi-purpose track gauge includes: a telescopic measuring scale with telescopic ends, a controller housed within the telescopic measuring scale, two rail top measuring scales that work together to measure the track gauge between two rails, and two sets of signal transmitters and receivers respectively mounted on the two rail top measuring scales.

The telescopic measuring scale also has input and output terminals respectively connected to the controller for inputting and outputting information. The telescopic measuring scale automatically extends outward by a predetermined length based on the input information to overlap, support, and position itself on the two adjacent rails. The two rail top measuring scales are vertically slidably mounted on the two telescopic ends of the telescopic measuring scale. The two sets of rail top measuring scales automatically slide downward by a predetermined distance based on the input information and are respectively close to the inner sidewalls of the two rails. The two sets of signal transmitters and receivers are used to transmit and receive signals to measure the track gauge between predetermined height positions on the two rails, or to guide the controller to adjust the position of the two rail top measuring scales so that they are in the same vertical plane and parallel when the two rail top measuring scales are not parallel in the same vertical plane.

[0014] Furthermore, the telescopic measuring ruler includes a hollow ruler body, a magnetic movable magnetic rack and a reference magnetic rack, and two sets of first drivers for driving the movable magnetic rack and the reference magnetic rack to move respectively; the two sets of first drivers are respectively disposed inside the ruler body, and are also respectively connected to a controller; the first ends of the movable magnetic rack and the reference magnetic rack are respectively connected to the corresponding first drivers, and the second ends of both ends extend outward from both ends of the ruler body; the two sets of rail-top measuring rulers are respectively perpendicularly connected to the second ends of the movable magnetic rack and the second ends of the reference magnetic rack.

[0016] Furthermore, the telescopic measuring ruler also includes two sets of fine-tuning mechanisms for respectively fine-tuning the telescopic extension of the moving magnetic rack and the reference magnetic rack. The two sets of fine-tuning mechanisms are respectively connected to the controller; one set of fine-tuning mechanisms is located inside the ruler body and the moving magnetic rack and is connected to the moving magnetic rack, while the other set of fine-tuning mechanisms is located inside the ruler body and the reference magnetic rack and is connected to the reference magnetic rack; the two sets of signal transmitters and receivers are also used to automatically control the two sets of fine-tuning mechanisms to operate according to the change in track gauge between the two rails, so that the moving magnetic rack and the reference magnetic rack extend and retract accordingly to adapt to the change in track gauge.

[0017] Furthermore, each fine-tuning mechanism includes a second drive motor fixed inside the ruler body and connected to the controller, a lead screw fixed to the output shaft of the second drive motor, and balls threaded onto the outer circle of the lead screw; the lead screw extends along the length of the ruler body into the corresponding movable magnetic rack or reference magnetic rack; the balls are connected to the corresponding movable magnetic rack or reference magnetic rack.

[0018] Furthermore, the telescopic measuring ruler also includes two sets of guide friction reduction mechanisms disposed within the movable magnetic rack and the reference magnetic rack. Each guide friction reduction mechanism includes: a third drive motor fixed within the corresponding movable magnetic rack or the reference magnetic rack, and a first roller fixedly connected to the outer circle of the output shaft of the third drive motor; the third drive motor is connected to a controller; the movable magnetic rack and the reference magnetic rack are respectively provided with windows for the bottom of the first roller to be exposed, and the bottom of the first roller extends out of the corresponding window and rolls and is supported on the top surface of the rail on the corresponding side.

[0019] Furthermore, each rail-top measuring scale includes a fourth actuator connected to the outer wall of the corresponding movable magnetic rack or reference magnetic rack, and a rail-top rack vertically set vertically to mesh with the corresponding fourth actuator; the fourth actuator is connected to a controller; the rail-top rack is used to move up and down and / or deflect left and right around the vertical end face under the action of the fourth actuator to reach the measuring point set at the height position on the rail, and after deflection, it closely adheres to the inner side of the corresponding side rail to adapt to the measurement when the bottom surface of the installed rail is a rail bottom slope with an incline.

[0020] Furthermore, the fourth drive includes two fourth drive motors and two second drive gears respectively connected to the two fourth drive motors. The two fourth drive motors are respectively connected to the controller. The back face of the rail top rack facing the fourth drive has a recessed mounting groove that extends along the height direction. The two sides of the mounting groove in the height direction are machined to form two gear grooves. The fourth drive is located in the mounting groove, and the two second drive gears are respectively meshed with and connected to the two gear grooves.

[0021] Furthermore, the rail top measuring ruler also includes a second roller for friction reduction and guidance. The second roller is connected to the bottom end of the rail top rack and is rotatably arranged around a vertical axis to fit closely against the inner surface of the corresponding side rail and roll along the inner surface of the rail.

[0022] Furthermore, each set of signal transmitters and receivers includes two signal transmitters located at the upper and lower ends of the rail-top measuring ruler, and a signal receiver connected to the outer surface of the rail-top measuring ruler; the two signal generators and the signal receivers are respectively connected to the controller, and the signal receivers also cover the entire outer surface of the rail-top measuring ruler.

When not in use, the two ends of the telescopic measuring ruler can be retracted as much as possible, ensuring the overall rigidity of the structure and preventing excessive deflection due to structural defects from affecting subsequent use, while also being convenient to carry. The telescopic measuring ruler is equipped with an input end and an output end. The input end is used to input signals to control the precise extension and retraction of the telescopic measuring ruler and the precise raising and lowering of the rail top measuring ruler. The output end is used to output and record data such as track gauge, levelness, and rail bottom slope. Thus, the basic parameters input through the input end can be used to measure different track gauges and different rail bottom measurement points, achieving multiple uses in one device and greatly reducing the complexity of measuring tools. At the same time, because... During use, only a few data points need to be entered to receive real-time feedback, greatly reducing errors from manual operation and improving measurement efficiency. Furthermore, the setup of two sets of signal transmitters and receivers not only simplifies track gauge measurement but also allows for more precise measurement. When the base of the rail supporting the track is a sloped rail base or when two rail top measuring rulers are laid out along the rail's extension direction, the two sets of signal transmitters and receivers send signals to the controller. The controller then controls the forward and backward movement of the telescopic measuring rulers or the deflection correction of the rail top measuring rulers, ensuring that the two rail top measuring rulers are positioned in a vertical plane perpendicular to the two rails and are parallel to each other. This significantly improves the adaptability and accuracy of track gauge measurement and enables track gauge measurement over longer distances.

[0043] The embodiments of the present invention will be described in detail below with reference to the accompanying drawings. However, the present invention can be implemented in many different ways as defined and covered below.

[0044] Reference Figure 1 and Figure 5A preferred embodiment of the present invention provides a multi-purpose track gauge, comprising: a telescopic measuring scale with telescopic ends, a controller 2 disposed within the telescopic measuring scale, two rail top measuring scales that cooperate to measure the track gauge between two rails, and two sets of signal transmitters and receivers disposed on the two rail top measuring scales. The telescopic measuring scale, the two rail top measuring scales, and the two sets of signal transmitters and receivers are respectively connected to the controller 2. The telescopic measuring scale is also provided with an input terminal 101 and an output terminal 102 respectively connected to the controller 2 for inputting and outputting information. The telescopic measuring scale is used to automatically extend outward by a predetermined length at both ends according to the input information to overlap, support, and position itself on the two adjacent rails. The two rail top measuring scales are respectively vertically slidably disposed on the two telescopic ends of the telescopic measuring scale. The two sets of rail top measuring scales are used to automatically slide downward by a predetermined distance according to the input information and respectively abut against the inner sidewalls of the two rails. Two sets of signal transmitters and receivers are used to transmit and receive signals to each other in order to measure the track gauge between the height positions set on the two rails, or to guide the controller 2 to adjust the position of the two rail top measuring rulers so that they are in the same vertical plane and parallel when the two rail top measuring rulers are not parallel in the same vertical plane.

[0045] When using the multi-purpose gauge ruler of this invention to measure the gauge of two adjacent rails, firstly, the controller 2 drives the first end of the telescopic measuring ruler to extend a preset length according to the signal input from the input terminal 101 to overlap the top surface of the corresponding rail. Then, the controller 2 drives the second end of the telescopic measuring ruler to extend. When the second end of the telescopic measuring ruler extends and the rail top measuring ruler installed on it touches the inner side of the rail, the extension of the second end of the telescopic measuring ruler will stop, thus achieving the positioning of the gauge. Next, the controller 2 controls the rail top measuring rulers on both sides to extend downward a preset distance to the measurement point at the preset height position of the rail. Finally, the distance between the set height positions of the two rails is measured through two sets of signal transmitters and receivers (the gap between the rails is the distance between the two rails at the same height position). When the two rail top measuring rulers are not in the same vertical plane and are not parallel to each other, the signal transmitters and receivers feed back the signal to the controller 2. The controller 2 controls the movement of the gauge ruler accordingly to make the two rail top measuring rulers in the same vertical plane and parallel to each other. Finally, the gauge is remeasured and adjusted.

[0046] The track gauge of this invention has a simple overall structure, is easy to manufacture, and has low production cost. When not in use, the two ends of the telescopic measuring ruler can be retracted as much as possible, ensuring the overall rigidity of the structure and preventing excessive deflection due to structural defects from affecting subsequent use, while also being convenient to carry. The telescopic measuring ruler is provided with an input end 101 and an output end 102. The input end 101 is used to input signals to control the precise extension and retraction of the telescopic measuring ruler and the precise raising and lowering of the rail top measuring ruler. The output end 102 is used to output and record data such as track gauge, levelness, and rail bottom slope. Thus, the basic parameters input through the input end 101 can realize the measurement of different track gauges and different rail bottom measuring points, achieving multiple uses in one device and greatly reducing the complexity of measuring tools. Furthermore, the use of two sets of signal transmitters and receivers not only simplifies track gauge measurement but also allows for real-time feedback when the supporting rail surface has a slope or when two rail top measuring rulers are laid out along the rail extension direction. The two sets of signal transmitters and receivers send signals to controller 2, which then controls the forward and backward movement of the ends of the telescopic measuring rulers or the deflection correction of the rail top measuring rulers. This ensures that the two rail top measuring rulers are located in a vertical plane perpendicular to the two rails and are parallel to each other, thereby greatly improving the adaptability and accuracy of track gauge measurement and enabling track gauge measurement over longer distances.

[0047] Optionally, such as Figure 1 As shown, the telescopic measuring ruler includes a hollow ruler body 11, a magnetic movable magnetic rack 12 and a reference magnetic rack 13, and two sets of first actuators 14 for respectively driving the movable magnetic rack 12 and the reference magnetic rack 13 to move. In this optional scheme, the input terminal 101 and the output terminal 102 are respectively provided on the ruler body 11. By inputting basic parameters through the input terminal 101, the controller 2 can control the first actuators 14 to extend the corresponding movable magnetic rack 12 or reference magnetic rack 13. Furthermore, the ruler body 11 is hollow, making the gauge ruler easy to handle. Figure 6 As shown, two sets of first actuators 14 are respectively disposed inside the ruler body 11, and are also respectively connected to the controller 2. The first ends of the movable magnetic rack 12 and the reference magnetic rack 13 are respectively connected to the corresponding first actuators 14, and the second ends of both ends extend outward from both ends of the ruler body 11. The two sets of rail-top measuring rulers are respectively vertically connected to the second ends of the movable magnetic rack 12 and the second ends of the reference magnetic rack 13.

[0048] Furthermore, such as Figure 1 As shown, the ruler body 11 is also equipped with a handle 103 for easy handling of the gauge ruler.

[0049] In this optional solution, such as Figure 3-6As shown, both the movable magnetic rack 12 and the reference magnetic rack 13 are hollow, and their upper surfaces are respectively machined with straight meshing teeth extending along their own length. The ruler body 11, the movable magnetic rack 12, and the reference magnetic rack 13 are all hollow, which facilitates the handling and transportation of the gauge ruler. The first driver 14 includes a first drive motor and a first drive gear connected to the first drive motor. The first drive gear meshes with the corresponding straight meshing teeth for transmission. The movable magnetic rack 12 and the reference magnetic rack 13 are entirely made of magnetic material, or only the parts of the two that overlap on the top surface of the rail are made of magnetic material. In actual design, the magnetic force of the movable magnetic rack 12 and the reference magnetic rack 13 is very small, which ensures that they are fixed on the top surface of the rail when they overlap, without affecting their extension and retraction or overall movement.

[0050] Preferably, such as Figure 5 As shown, the telescopic measuring ruler also includes two sets of fine-tuning mechanisms 15 for respectively fine-tuning the telescopic amount of the movable magnetic rack 12 and the reference magnetic rack 13. The two sets of fine-tuning mechanisms 15 are respectively connected to the controller 2. One set of fine-tuning mechanisms 15 is located within the ruler body 11 and the movable magnetic rack 12, and is connected to the movable magnetic rack 12; the other set of fine-tuning mechanisms 15 is located within the ruler body 11 and the reference magnetic rack 13, and is connected to the reference magnetic rack 13. The two sets of signal transmitters and receivers are also used to automatically control the two sets of fine-tuning mechanisms 15 according to the change in track gauge between the two rails, so that the movable magnetic rack 12 and the reference magnetic rack 13 extend and retract accordingly to adapt to the change in track gauge. When continuous inspection of the track gauge is required, the gauge ruler slides along the length of the rails. When the distance between the two rails changes, the two sets of signal transmitters and receivers detect the change and feed back the change to the controller 2. The controller 2 then controls the fine-tuning mechanism 15 to activate, so that the corresponding movable magnetic rack 12 or reference magnetic rack 13 extends and retracts to adapt to the change in width between the rails.

[0051] In this preferred embodiment, such as Figure 5As shown, each fine-tuning mechanism 15 includes a second drive motor 151 fixed inside the ruler body 11 and connected to the controller 2, a lead screw 152 fixed to the output shaft of the second drive motor 151, and ball bearings 153 threaded onto the outer circumference of the lead screw 152. The lead screw 152 extends along the length of the ruler body 11 into the corresponding movable magnetic rack 12 or reference magnetic rack 13. The ball bearings 153 are connected to the corresponding movable magnetic rack 12 or reference magnetic rack 13. After the movable magnetic rack 12 and reference magnetic rack 13 are initially positioned, the second drive motor 151 starts to drive the lead screw 152 to rotate. The rotation of the lead screw 152 drives the ball bearings 153 to move along the length of the lead screw 152, thereby causing the connected movable magnetic rack 12 or reference magnetic rack 13 to extend and retract again for precise positioning. When the rail top measuring ruler is pressed against the inner wall of the rail, the second drive motor 151 will feed back an electrical signal to the controller 2, and the controller 2 can lock the second drive motor 151 at this time.

[0052] In this preferred embodiment, the fine adjustment of the movable magnetic rack 12 and the reference magnetic rack 13 is achieved by the internal fine adjustment mechanism 15. At the same time, once the initial positioning of the track gauge is determined, no further significant adjustments are made. When the track gauge ruler moves along the length of the rail, and encounters changes in track gauge, the fine adjustment mechanism 15 finely adjusts the extension and retraction of the movable magnetic rack 12 and the reference magnetic rack 13 to adapt to the changes in track gauge. The track gauge ruler of this invention can continuously measure within the length of the rail, which is more accurate than the traditional point-to-line measurement method and is more practical for high-speed railways.

[0053] Preferably, such as Figure 6 As shown, the telescopic measuring ruler also includes two sets of guide friction reduction mechanisms 16 respectively disposed within the movable magnetic rack 12 and the reference magnetic rack 13. Each guide friction reduction mechanism 16 includes: a third drive motor 161 fixed within the corresponding movable magnetic rack 12 or reference magnetic rack 13, and a first roller 162 fixedly connected to the outer circle of the output shaft of the third drive motor 161. The third drive motor 161 is connected to the controller 2. The movable magnetic rack 12 and the reference magnetic rack 13 are respectively provided with windows for exposing the bottom of the first roller 162. After the bottom of the first roller 162 extends out of the corresponding window, it rolls and is supported on the top surface of the corresponding side rail. In this preferred embodiment, the guide friction reduction mechanism 16 enables the gauge ruler to move continuously on the top surface of the rail as needed. During movement, the first roller 162 prevents sliding friction, mechanical damage, and movement irregularities on the rail. Furthermore, the first roller 162 is a wide roller with a larger width to improve the stability of the gauge ruler's movement.

[0054] Optionally, such as Figure 1 , Figure 3-5As shown, each rail-top measuring scale includes a fourth actuator connected to the outer wall of the corresponding movable magnetic rack 12 or reference magnetic rack 13, and a rail-top rack 32 vertically arranged on the scale body 11 and meshing with the corresponding fourth actuator. The fourth actuator is connected to the controller 2. The rail-top rack 32 is used to move up and down and / or deflect left and right around the vertical end face under the action of the fourth actuator to reach the measuring point at the set height position on the rail, and after deflection, it is in close contact with the inner side of the corresponding side rail to adapt to the measurement when the bottom surface of the installed rail has an inclined slope.

[0055] In this optional solution, such as Figure 2 As shown, the fourth actuator includes two fourth drive motors and two second drive gears 311 connected to the two fourth drive motors respectively. The two fourth drive motors are respectively connected to the controller 2. In this optional embodiment, the two fourth drive motors are controlled independently. The rail-top rack 32 has a recessed mounting groove extending along the height direction on its back surface facing the fourth actuator. The two sides of the mounting groove in the height direction are machined to form two gear grooves 321. The fourth actuator is located in the mounting groove, and the two second drive gears 311 are respectively engaged with the two gear grooves 321. During operation, each rail-top rack 32 is driven by two second drive gears 311 for lifting and lowering, ensuring accurate positioning of the measurement point under the rail during the lifting and lowering process. On the other hand, the two second drive gears 311 are controlled by two corresponding fourth drive motors. The controller 2 determines the rotation direction and working state of each fourth drive motor through signal input. When the rotation direction of the two fourth drive motors is opposite or the speed is different, the corresponding rail-top rack 32 can be rotated accordingly to keep it close to the inner side of the corresponding side rail. This adapts to the measurement when the bottom surface of the installed rail has an inclined slope, thus improving the adaptability range of the track gauge measurement.

[0056] Preferably, such as Figure 2 As shown, the rail-top measuring ruler also includes a second roller 33 for friction reduction and guidance. The second roller 33 is connected to the bottom end of the rail-top rack 32 and is rotatable around a vertical axis to closely adhere to the inner surface of the corresponding side rail and roll along the inner surface of the rail. The second roller 33 can adjust the length of the rail-top rack 32 without damaging the measuring tool and the rail when there is unevenness on the side of the rail, and can also travel on the side of the rail, saving manual operation and avoiding errors.

[0057] Optionally, such as Figure 2 As shown, each set of signal transmitters and receivers includes two signal transmitters 41 located at the top and bottom of the rail-top measuring scale, and a signal receiver 42 connected to the outer surface of the rail-top measuring scale. The two signal generators and the signal receiver 42 are respectively connected to the controller 2, and the signal receiver 42 also covers the entire outer surface of the rail-top measuring scale.

[0058] During operation, each of the two rail-top racks 32 is equipped with a signal transmitter 41 and a signal receiver 42 facing each other. The initial position of each signal transmitter 41 and signal receiver 42 on the rail-top rack 32 is fixed. When there is no deviation, the signals emitted by the signal transmitters 41 on the two rail-top racks 32 are at the same position on the two signal receivers 42, which serves as the initial zero point of the two rail-top racks 32. When the two rail-top racks 32 experience mechanical deviation, the relative position of the signals emitted by the two signal transmitters 41 on the two signal receivers 42 changes. After receiving the deviation signal, the controller 2 processes it and controls the corresponding traveling motor and gear motor to correct the relative position of the two rail-top racks 32, as detailed below:

[0059] 1. Two sets of signal transmitters and receivers can be used to determine whether the rail-top rack 32 has been accurately raised and lowered to the designated position, thereby enabling track gauge measurement over a longer distance.

[0060] 2. When measuring the gauge of a sloping rail, the signal transmitter and receiver obtain the slope of the rail base slope based on the signal feedback and feed it back to the controller 2. The controller 2 adjusts the relative position of the rail top rack 32 according to the slope of the signal input. At this time, the rail top rack 32 will rotate accordingly due to the rotation of the two fourth drive motors in different directions. At this time, the signal emitted by the signal transmitter 41 changes the position of the signal receiver 42. The position signal of the receiving point can be compared with the signal zero point to determine whether the rotation is in place, thereby controlling the working state of the fourth drive motor.

[0061] 3. When the gauge ruler moves along the length of the rail, when the gauge changes, the signal transmitter and receiver will receive feedback to obtain the gauge change value and feed it back to the controller 2. The controller 2 will control the fine adjustment mechanism 15 according to the gauge value input by the signal to adjust the extension and retraction of the moving magnetic rack 12 and the reference magnetic rack 13 to adapt to the gauge change.

[0062] The above description is merely a preferred embodiment of the present invention and is not intended to limit the invention. Various modifications and variations can be made to the present invention by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
