Description

Technical Field

[0001] The invention relates to the technical field of railway construction track gauges, in particular to a multi-purpose track gauge. Background Art

[0002] The accuracy index of the traditional mechanical scale track gauge is affected and restricted by factors such as the structure of the track gauge, operating conditions, measurement technology level of the users, and manufacturing level. Although the measurement performance at room temperature can meet the requirements of relevant standards and measurement technical regulations, it cannot be fully guaranteed to meet the relevant requirements under other environmental conditions.

[0003] The birth of digital track gauge has opened up a new way to solve the above problems, such as patent number CN118029211A, a track gauge for precise adjustment and a method for shifting the track gauge, patent number CN220704220U, a railway construction track gauge, etc. However, both the traditional mechanical track gauge and the existing digital track gauge have the following disadvantages:

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

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

[0006] 3. Both have a short service life and are easy to wear, which can easily cause measurement errors. In addition, due to problems such as rust during use, the accuracy of the track gauge is reduced, and the disassembly and assembly work is more difficult;

[0007] 4. The track gauge is only placed on the track during use, and will deviate when encountering external forces, causing measurement errors;

[0008] 5. The track 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. When measuring, only a certain reference surface can be measured vertically downward from the top of the rail. When encountering the bottom slope of the rail, the longitudinal reference surface of the rail cannot be accurately measured;

[0043] The embodiments of the present invention are 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 5The preferred embodiment of the present invention provides a multi-purpose track gauge, comprising: a telescopic measuring ruler with telescopically arranged ends, a controller 2 arranged in the telescopic measuring ruler, two rail top measuring rulers that cooperate to measure the track gauge between two rails, and two groups of signal transmitters and receivers arranged on the two rail top measuring rulers, wherein the telescopic measuring ruler, the two rail top measuring rulers, and the two groups of signal transmitters and receivers are respectively connected to the controller 2. The telescopic measuring ruler is also provided with an input terminal 101 and an output terminal 102 that are respectively connected to the controller 2 to input and output information respectively. The telescopic measuring ruler is used to automatically extend outwards by a set length at both ends according to the input information, so as to overlap and support and position on two adjacent rails. The two rail top measuring rulers are respectively vertically slidably arranged on the two telescopic ends of the telescopic measuring ruler, and the two groups of rail top measuring rulers are used to automatically slide downward and extend out by a set distance according to the input information, and respectively close to the inner side walls of the two rails. The two sets of signal transmitters and receivers are used to transmit and receive signals to each other to measure the gauge between the height positions set on the two rails, or when the two rail top measuring scales are not parallel in the same vertical plane, the instructing controller 2 to adjust the position states of the two rail top measuring scales so that the two are located in the same vertical plane and parallel.

[0045] When the multi-purpose track gauge ruler of the present invention is used to measure the track gauge of two adjacent rails, first, the controller 2 drives the first end of the telescopic measuring ruler to extend a preset length to overlap the top surface of the rail on the corresponding side according to the signal input by the input terminal 101, and then the controller 2 drives the second end of the telescopic measuring ruler to extend. When the rail top measuring ruler installed on the second end of the telescopic measuring ruler touches the inner side of the rail during the extension process, the extension of the second end of the telescopic measuring ruler will stop, and the position positioning of the track gauge is achieved at this time; then the controller 2 controls the rail top measuring rulers on both sides to extend downward by a preset distance to drop to the measuring point at the preset height position of the rail, and finally the distance between the set height positions of the two rails is measured by two sets of signal transmitters and receivers (the gap between the rails is the distance between the two rails at the same height position), and when the two rail top measuring rulers are not in the same vertical plane and are not parallel to each other, the signal transmitter and receiver feeds back the signal to the controller 2, and the controller 2 correspondingly controls the action of the track gauge ruler to make the two rail top measuring rulers in the same vertical plane and parallel to each other, and finally the adjusted track gauge is re-measured.

[0046] The track gauge ruler of the present invention has a simple overall structure, is easy to prepare and has a low manufacturing cost. When the track gauge ruler is not in use, the two ends of the telescopic measuring ruler can be retracted as much as possible, which can ensure the rigidity of the overall structure, prevent the subsequent use from being affected by a large deflection due to its own structural defects, and is 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 a signal to control the precise telescopic amount of the telescopic measuring ruler and the precise lifting and lowering of the rail top measuring ruler. The output end 102 is used to output and record data such as the track gauge, levelness, and rail bottom slope. Therefore, the basic parameters input through the input end 101 can realize the measurement of different track gauges and different measuring points under the rail, so that one machine can be used for multiple purposes, greatly reducing the complexity of the measuring tool. At the same time, since only a few data need to be input during use to obtain real-time feedback, the error of manual operation is greatly reduced, and the measurement efficiency is improved; furthermore, due to the setting of the two sets of signal transmitters and receivers, not only the track gauge measurement operation is simple, but also when the bottom surface used to support the rail is a rail bottom slope with a slope or two rail top measuring rulers are arranged front and back along the extension direction of the rail, the two sets of signal transmitters and receivers feedback signals to the controller 2, and the controller 2 controls the front and back movement of the two ends of the telescopic measuring ruler, or the deflection correction of the rail top measuring ruler, so that the two rail top measuring rulers are located in a vertical plane perpendicular to the two rails and parallel to each other, thereby greatly improving the adaptability and measurement accuracy of the track gauge measurement, and can achieve track gauge measurement at a longer distance.

[0047] Alternatively, if Figure 1 As shown, the telescopic measuring ruler includes a hollow ruler body 11, a mobile magnetic rack 12 and a reference magnetic rack 13 with magnetism, and two sets of first drivers 14 for driving the mobile magnetic rack 12 and the reference magnetic rack 13 to move. In this optional solution, the input end 101 and the output end 102 are respectively arranged on the ruler body 11, and the controller 2 can control the first driver 14 to move by inputting basic parameters through the input end 101, so that the corresponding mobile magnetic rack 12 or the reference magnetic rack 13 is extended, and the ruler body 11 is hollow, so it is easy to take the track gauge. Figure 6 As shown, two sets of first drivers 14 are respectively arranged in the ruler body 11, and both are also respectively connected to the controller 2, the first ends of the moving magnetic rack 12 and the reference magnetic rack 13 are respectively connected to the corresponding first drivers 14, and the second ends of the two ends are respectively extended outward from the two ends of the ruler body 11. The two sets of rail top measuring rulers are respectively vertically connected to the second end of the moving magnetic rack 12 and the second end of the reference magnetic rack 13.

[0048] Furthermore, if Figure 1 As shown, a handle 103 is also provided on the ruler body 11 to facilitate the transportation of the track gauge ruler.

[0049] In this option, if Figure 3-6As shown, both the movable magnetic rack 12 and the reference magnetic rack 13 are hollow, and the upper end surfaces of the two are respectively processed to form linear meshing teeth extending along their own length direction; the ruler body 11, the movable magnetic rack 12, and the reference magnetic rack 13 are hollow, so as to facilitate the taking and carrying of the track gauge. The first driver 14 includes a first drive motor, and a first drive gear connected to the first drive motor, and the first drive gear is meshed with the corresponding linear meshing teeth for transmission. The movable magnetic rack 12 and the reference magnetic rack 13 are made of magnetic material as a whole, 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, so that it can ensure that the two are fixed on the top surface of the rail when overlapping, and does not affect their own telescopic action and overall movement.

[0050] Preferably, if Figure 5 As shown, the telescopic measuring ruler also includes two groups of fine adjustment mechanisms 15 for respectively finely adjusting the extension and contraction of the moving magnetic rack 12 and the reference magnetic rack 13, and the two groups of fine adjustment mechanisms 15 are respectively connected to the controller 2. One group of fine adjustment mechanisms 15 is arranged in the ruler body 11 and the moving magnetic rack 12, and is connected to the moving magnetic rack 12, and the other group of fine adjustment mechanisms 15 is arranged in the ruler body 11 and the reference magnetic rack 13, and is connected to the reference magnetic rack 13. The two groups of signal transmitters and receivers are also used to enable the controller 2 to automatically control the two groups of fine adjustment mechanisms 15 to operate according to the change in the track gauge between the two rails, so that the moving magnetic rack 12 and the reference magnetic rack 13 are correspondingly extended and contracted to adapt to the change in the track gauge. When the track gauge of the rail needs to be continuously checked, the track gauge ruler slides along the length direction of the rail. When the distance between the two rails changes, the two groups of signal transmitters and receivers detect the change and feed back the change to the controller 2. The controller 2 controls the fine adjustment mechanism 15 to start, so that the corresponding moving magnetic rack 12 or the reference magnetic rack 13 is extended and contracted to adapt to the change in the width between the rails.

[0051] In this preferred embodiment, Figure 5As shown, each fine adjustment mechanism 15 includes a second drive motor 151 fixed in the ruler body 11 and connected to the controller 2, a screw rod 152 fixed to the output shaft of the second drive motor 151, and a ball 153 threadedly mounted on the outer circumference of the screw rod 152. The screw rod 152 extends along the length direction of the ruler body 11 to the corresponding moving magnetic rack 12 or the reference magnetic rack 13. The ball 153 is connected to the corresponding moving magnetic rack 12 or the reference magnetic rack 13. After the moving magnetic rack 12 and the reference magnetic rack 13 are initially positioned, the second drive motor 151 is started to drive the screw rod 152 to rotate, and the rotation of the screw rod 152 drives the ball 153 to move along the length direction of the screw rod 152, thereby driving the connected moving magnetic rack 12 or the reference magnetic rack 13 to extend and retract again for precise positioning. When the rail top measuring ruler is pressed against the inner side wall of the rail, the second drive motor 151 will feedback to the controller 2 through an electrical signal, 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, when the initial positioning of the track gauge is determined, the overall adjustment is no longer required. When the track gauge moves along the length of the rail as a whole, when the track gauge changes, the fine adjustment mechanism 15 fine adjusts the extension and retraction of the movable magnetic rack 12 and the reference magnetic rack 13 to adapt to the change in track gauge. The track gauge of the present 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, if Figure 6 As shown, the telescopic measuring ruler also includes two sets of guide and friction-reducing mechanisms 16 respectively arranged in the mobile magnetic rack 12 and the reference magnetic rack 13, each guide and friction-reducing mechanism 16 includes: a third drive motor 161 fixed in the corresponding mobile magnetic rack 12 or the 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. Windows for exposing the bottom of the first roller 162 are respectively provided on the mobile magnetic rack 12 and the reference magnetic rack 13, and the bottom of the first roller 162 is extended from the corresponding window and then rolled and supported on the top surface of the steel rail on the corresponding side. In this preferred embodiment, by setting the guide wear reduction mechanism 16, the track gauge as a whole can move continuously on the rail top surface as needed, and due to the setting of the first roller 162, there is no sliding friction, no mechanical damage, no movement irregularity and other damage and failure to the rail during movement; further, the first roller 162 is a wide roller with a larger width to improve the stability of the movement of the track gauge.

[0054] Alternatively, if Figure 1 , Figure 3-5As shown, each rail top measuring ruler includes a fourth driver connected to the outer wall surface of the corresponding moving magnetic rack 12 or the reference magnetic rack 13, and a rail top rack 32 vertically arranged perpendicular to the ruler body 11 and meshingly connected to the corresponding fourth driver. The fourth driver is connected to the controller 2. The rail top rack 32 is used to rise and fall and / or deflect left and right around the vertical end face under the action of the fourth driver to reach the measuring point set at the height position on the rail, and after deflection, it is close to the inner side surface of the corresponding side rail to adapt to the measurement when the rail bottom surface of the installed rail is a rail bottom slope with an inclined slope.

[0055] In this option, if Figure 2 As shown, the fourth driver includes two fourth drive motors, two second drive gears 311 respectively connected to the two fourth drive motors, and the two fourth drive motors are respectively connected to the controller 2. In this optional solution, the two fourth drive motors are controlled to work separately. A mounting groove which is concave and extends in the height direction is provided on the back surface of the rail top rack 32 facing the fourth driver, and two side edges in the height direction of the mounting groove are processed to form two gear grooves 321. The fourth driver is located in the mounting groove, and the two second drive gears 311 are respectively meshed and connected to the two gear grooves 321. During operation, each rail top rack 32 has two second drive gears 311 to drive the lifting and lowering, which can ensure the precise positioning of the measuring point under the rail during the lifting and lowering process; on the other hand, the two second drive gears 311 have corresponding two fourth drive motors to control them respectively, and the controller 2 determines the rotation direction and working state of each fourth drive motor through signal input. When the rotation directions of the two fourth drive motors are opposite or the rotation speeds are different, the corresponding rail top rack 32 can be rotated accordingly to keep close to the inner side surface of the corresponding side rail, thereby adapting to the measurement when the bottom surface of the installed rail is a rail bottom slope with an inclined slope, thereby improving the adaptability range of the track gauge measurement.

[0056] Preferably, if Figure 2 As shown, the rail top measuring ruler also includes a second roller 33 for wear reduction and guiding. The second roller 33 is connected to the bottom end of the rail top rack 32 and is rotatably arranged around a vertical axis so as to be closely attached to the inner side of the corresponding side rail and roll along the inner side of the rail. The second roller 33 can not only adjust the length of the rail top rack 32 when there is unevenness on the side of the rail without damaging the measuring tool and the rail, but also can drive on the side of the rail, saving human operation and avoiding errors.

[0057] Alternatively, if Figure 2 As shown, each group of signal transmitters and receivers includes two signal transmitters 41 respectively arranged at the upper and lower ends of the rail top measuring scale, and a signal receiver 42 connected to the outer side 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 is also distributed over the entire outer side of the rail top measuring scale.

[0058] During operation, the two rail top racks 32 are provided with signal transmitters 41 and signal receivers 42 facing each other, and the initial positions of each signal transmitter 41 and signal receiver 42 on the rail top rack 32 are 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 is used as the initial zero point of the two rail top racks 32. When the two rail top racks 32 have mechanical deviation, the relative positions of the signals emitted by the two signal transmitters 41 on the two signal receivers 42 change. After receiving the deviation signal, the controller 2 controls the corresponding driving motor and gear motor to correct the relative positions of the two rail top racks 32 through processing, as follows:

[0059] 1. Two sets of signal transmitters and receivers can be used to determine whether the rail top rack 32 is accurately raised or lowered to the specified position, thereby enabling longer distance gauge measurement.

[0060] 2. When measuring the gauge of a steel rail with a slope, the signal transmitter and receiver obtains the slope of the rail bottom slope according to the signal feedback and feeds 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 track gauge moves along the length direction of the rail as a whole, when the track gauge changes, the signal transmitter and receiver feedback the situation to obtain the spacing change value and feed it back to the controller 2. The controller 2 controls the fine adjustment mechanism 15 according to the spacing value input by the signal to adjust the extension and contraction amount of the moving magnetic rack 12 and the reference magnetic rack 13 to adapt to the change of the track gauge.

[0062] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
