Description

Technical Field

[0001] This utility model belongs to the technical field of track detection devices, specifically relating to a comprehensive inspection instrument for contact rail, induction plate, and track static geometric parameters. Background Technology

[0002] To ensure the safety of rail transportation, it is necessary to inspect the rail equipment and promptly identify and address any defects. Rail inspection involves measuring various geometric parameters, including those of subway tracks, such as static track parameters, contact rail geometry, and sensor plate geometry.

[0003] Currently, the detection of track static parameters is sometimes done manually with a track gauge, and sometimes automatically with a track inspection instrument. The track inspection instrument used to detect track static parameters can be pushed on the track. The track inspection instrument uses gyroscopes, tilt sensors, linear displacement sensors, rotary encoders, etc. to measure track geometric parameters such as gauge, level, elevation, direction, and torsion (triangular pit). When in use, the track inspection instrument is placed on the track and pushed manually (at about 5 km / h) to complete the measurement of track geometric parameters.

[0004] However, the detection of contact rail geometric parameters and sensor plate geometric parameters is mainly done using mechanical special measuring rulers. Manual measurement of geometric parameters involves taking measurements at regular intervals along the line, requiring continuous bending over, which is labor-intensive and inefficient. Furthermore, much of the measurement work is done at night when the subway is not in operation, where poor lighting and fatigue can easily lead to misreading of data by the measuring personnel, resulting in human error. In addition, the accuracy of mechanical measuring instruments is not high. Utility Model Content

[0036] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0037] In one embodiment, a comprehensive inspection instrument for the static geometric parameters of a contact rail, induction plate, and track is provided, such as... Figure 1-4 As shown, the comprehensive inspection instrument for static geometric parameters of contact rail, induction plate, and track includes a traveling frame for moving on the track (running rail). The traveling frame houses a track inspection component, a contact rail measurement component, an induction plate measurement component, and a host computer. The track inspection component detects the geometric parameters of the track, the contact rail measurement component detects the geometric parameters of the contact rail, the induction plate measurement component detects the geometric parameters of the induction plate, and the host computer receives the geometric parameters and generates corresponding data charts. The instrument also includes a battery module for providing power to the relevant components.

[0038] Combination Figure 2 As shown, the track inspection assembly includes a linear displacement sensor 19 for measuring track gauge, an ultrasonic sensor for identifying sleepers, an inclination sensor for measuring track superelevation, a gyroscope for measuring track elevation and orientation, and a data acquisition circuit board. The ultrasonic sensor and inclination sensor are mounted on the underside of the running frame. Figure 2 The ultrasonic sensor and tilt sensor are installed on the underside of the walking frame. Figure 2The image is obscured and not shown. In this embodiment, a gyroscope and data acquisition box 5 is also provided on the walking frame. The gyroscope and data acquisition circuit board are housed in the gyroscope and data acquisition box 5. The gyroscope includes two high-precision fiber optic gyroscopes installed inside the gyroscope and data acquisition box 5. The linear displacement sensor 19, ultrasonic sensor, tilt sensor, rotary encoder 22, and gyroscope are all connected to the data acquisition circuit board. The data acquisition circuit board collects the data output from each sensor and uploads it to the host computer. By setting up the gyroscope and data acquisition box 5, the two main electrical components, the gyroscope and the data acquisition circuit board, are centrally installed in the box and can be disassembled as a whole for convenient maintenance and periodic calibration.

[0039] In this embodiment, the host computer is a laptop computer 4. The data acquisition circuit board is connected to the laptop computer 4 via wired or wireless means. For example, the data acquisition circuit board completes the data acquisition of all track geometry parameter measurement sensors and, after preprocessing, uploads the data to the host computer laptop computer 4 via Bluetooth or RS232 serial interface. The data processing software in the laptop computer 4 completes the calculation and storage of various geometric parameters and outputs various reports.

[0040] Combination Figure 1 As shown, the contact rail measurement assembly includes a first measuring arm 7 mounted on a walking frame, and a first laser sensor 6 is provided on the first measuring arm 7. The first laser sensor 6 is used to scan the contour of the contact rail surface and measure the distance from each point to the first laser sensor 6. The first laser sensor 6 uploads the measured data to a laptop computer 4 via a network cable.

[0041] Combination Figure 1 As shown, the sensing plate measurement assembly includes a second measuring arm 11 mounted on the middle of the walking frame. A second laser sensor 10 is provided on the second measuring arm 11. The second laser sensor 10 is used to scan the sensing plate and measure the distance from each point to the second laser sensor 10. The second laser sensor 10 uploads the measured data to the laptop computer 4 via a network cable.

[0042] The induction plate here is an aluminum alloy plate installed between the two rails along the subway line. The linear motor used in urban rail transit vehicles is a linear induction motor with a stator. Its structure is equivalent to cutting and unfolding a rotary motor radially into a straight line. The stator (primary coil) is located on the bogie at the bottom of the vehicle, and the rotor (secondary coil) is the induction plate, located in the middle of the track. When energized, the stator mounted on the bogie generates a moving magnetic field between itself and the induction plate laid in the middle of the track. The interaction (attraction and repulsion) between these magnetic forces generates traction. By changing the direction of the magnetic field, the vehicle can be driven and braked. Therefore, the induction plate is one of the key components in the linear motor system of urban rail transit.

[0043] The geometric parameters measured for the induction plates include the gap between the ends of two adjacent induction plates and the vertical distance between the top surface of the induction plate and the top surface of the adjacent track. The data measured by the second laser sensor 10 is uploaded to the laptop computer 4 via a network cable, where data processing software calculates the induction plate gap and horizontal value (the vertical distance between the top surface of the induction plate and the top surface of the adjacent running track) based on a mathematical model.

[0044] The measurement principle of the interval between the two sensing plates is as follows: Figure 8 As shown:

[0045] The second laser sensor is installed in the center of the walking frame. Its scanning line cd forms an angle β with the transverse direction, which is 12.597 degrees. When it passes the joint between sensor plates A and B, its scanning line intersects at points m and n respectively. The length L of line segment mn can be calculated. Therefore, the gap h between sensor plates A and B is calculated as follows:

[0046] h = L × sinβ.

[0047] The principle of measuring the horizontal value of the sensor plate is as follows: Figure 9 As shown:

[0048] The second laser sensor is installed 700mm above the center of the walking frame. The scanning range of the second laser sensor covers the entire width of the sensing plate, meaning it can measure the distance from each point on the scanning line to the second laser sensor. Let the measured distance from point A on the sensing plate to the second structural sensor be h, then the horizontal value c of the sensing plate is:

[0049] c = hb

[0050] In the formula, h is measured by the second laser sensor, and b is the distance from the sensor to the track plane, which remains fixed after the sensor is installed.

[0051] Furthermore, in another embodiment, such as Figure 1-4 As shown, the traveling frame of the contact rail, induction plate and track static geometric parameter comprehensive inspection instrument includes a crossbeam 1 and a longitudinal beam 2 on the left side of the crossbeam 1. The crossbeam 1 and the longitudinal beam 2 form a T-shaped structure, which can maintain the stability of traveling on the track. The T-shaped traveling frame is non-removable, avoiding measurement errors caused by repeated disassembly and assembly, reducing the time for on-track assembly and improving work efficiency.

[0052] The main body of the crossbeam 1 and the longitudinal beam 2 is made of I-beam alloy material, and weight-reducing holes are set on the I-beam alloy material, which has the characteristics of high structural strength, sturdiness and durability, and light weight. At the bottom of the end of the crossbeam 1 away from the longitudinal beam 2, a first traveling wheel 14 is provided for traveling on the track. At the bottom of the front and rear ends of the longitudinal beam 2, a second traveling wheel 20 and a third traveling wheel 16 are respectively installed for traveling on the track. The first traveling wheel 14, the second traveling wheel 20 and the third traveling wheel 16 are all cylindrical rollers. The positions of the first traveling wheel 14, the second traveling wheel 20 and the third traveling wheel 16 at the bottom of the traveling frame are matched with the track spacing.

[0053] Furthermore, in another embodiment, such as Figure 1-4 As shown, the contact rail, induction plate, and track static geometric parameter comprehensive inspection instrument has a first measuring wheel 15 located inside the first traveling wheel 14 at the bottom of the crossbeam 1 for traveling along the inner side of the track. At the front and rear ends of the longitudinal beam 2, inside the second traveling wheel 20 and the third traveling wheel 16 respectively, are second measuring wheels 27 and third measuring wheels 17 for traveling along the inner side of the track. Under the action of spring force, the first measuring wheel 15 is close to the gauge measurement point 16mm vertically downward from the top surface of the rail. Changes in the gauge cause changes in the output of the linear displacement sensor. The measuring wheels are mounted on the bottom of the traveling frame via brackets. A turnout clutch is provided in the crossbeam 1 for tightening the measuring wheel brackets. The function of the turnout clutch is that when the comprehensive inspection instrument passes a turnout, by pulling the clutch handle, the first measuring wheel 15 on the crossbeam leaves the track, allowing the traveling wheels at the bottom of the traveling frame to smoothly pass through the turnout. The first measuring wheel 15 can be retracted or lowered by operating the clutch handle 18 of the turnout clutch. When the traveling frame is traveling normally on the track, the first measuring wheel 15 is in the lowered state and travels close to the rail. When it encounters a turnout, the first measuring wheel 15 is in the retracted state.

[0054] Furthermore, in another embodiment, such as Figure 2 As shown, a rotary encoder 22 is installed at the third traveling wheel 16 of the contact rail, induction plate and track static geometric parameter comprehensive inspection instrument. When the third traveling wheel 16 rotates one revolution, the rotary encoder 22 senses and outputs 1000 pulse signals. The rotary encoder 22 sends the pulse signals to the data acquisition circuit board to complete the mileage measurement. The data acquisition circuit board uploads the measured mileage to the laptop computer 4.

[0055] Furthermore, in another embodiment, such as Figure 1As shown, the contact rail measuring component in this comprehensive inspection instrument for static geometric parameters of contact rail, induction plate, and track is a lower contact rail measuring component. This component is used to detect the geometric parameters of the lower contact type contact rail. The first measuring arm 7 is tilted downwards, and the first laser sensor 6 is installed at the end of the first measuring arm 7. The optical center angle of the first laser sensor 6 is 35°. Combined with... Figure 10 As shown, the contact rail is a special power supply device laid parallel to the track along the subway line to supply power to the electric multiple units (EMUs). It is also known as the third rail. Subway vehicles obtain power through contact shoes that connect with the contact rail. Depending on how the contact shoes draw current from the contact rail, the contact rail can be installed in three ways: upper contact, lower contact, and side contact. Figure 10 middle, Figure 10 -(a) is a schematic diagram of the contact installation on the contact rail. Figure 10 -(b) is a schematic diagram of the contact installation under the contact rail. Figure 10 -(c) is a schematic diagram of the contact rail side contact installation. Since the contact surface of the lower contact rail is located on the lower side, the lower contact rail measuring assembly here sets the first measuring arm 7 to be tilted downwards so that when the first laser sensor 6 is installed at the end of the first measuring arm 7, it can scan the contact surface located at the bottom of the contact rail at an angle upwards. The aforementioned optical center angle of 35° for the first laser sensor 6 refers to the installation angle of the first laser sensor 6 being 35°, that is, the angle between the scanning line of the first laser sensor 6 and the horizontal plane is 35°. This angle is set to avoid trackside equipment installed on the roadbed.

[0056] Combination Figure 6 As shown, the measurement principle of the first laser sensor 6 in the lower contact rail measurement assembly is as follows:

[0057] The first laser sensor 6 scans at a 35-degree angle to the horizontal plane, scanning the contour of the contact rail. The data is then uploaded to the laptop 4 via a network cable. The data processing software in the laptop 4 calculates the distance d using a mathematical model. The guide height h (the vertical distance from the top surface of the contact rail to the top surface of the adjacent running rail) is calculated as follows:

[0058] h = d × sin35 - s = 0.574 × ds

[0059] In the formula, s is the distance from the first laser sensor to the top surface of the running track, and this value is fixed after the measurement components are assembled.

[0060] The pull-out value 'a' (the shortest horizontal distance from the center of the contact rail to the inner side of the adjacent running rail) is calculated as follows:

[0061] a = b + c + g

[0062] Where b is a fixed value, determined after the component is assembled and remains unchanged. g is the distance from the center of the contact rail to the optical center line of the first laser sensor, which can be obtained by analyzing the laser scanning line.

[0063] c = d × cos35 = 0.819 × d

[0064] Therefore, the output value a = 0.819 × d + b + g.

[0065] Furthermore, in another embodiment, such as Figure 5 As shown, the contact rail measuring component in this comprehensive inspection instrument for static geometric parameters of contact rail, induction plate, and track is an upper contact rail measuring component. This component is used to detect the geometric parameters of the upper contact type contact rail. The first measuring arm 37 is tilted upwards, and the first laser sensor 36 is installed at the end of the first measuring arm 37. The optical center angle of the first laser sensor 36 is 45°. Since the contact surface of the upper contact type contact rail is located on the upper side, the upper contact rail measuring component here sets the first measuring arm 37 to be tilted upwards so that when the first laser sensor 36 is installed at the end of the first measuring arm 37, it can scan the contact surface located at the top of the contact rail at an angle upwards. Similarly, the aforementioned 45° optical center angle of the first laser sensor 36 refers to the installation angle of the first laser sensor 36 being 45°, that is, the angle between the scanning line of the first laser sensor 36 and the horizontal plane is 45°.

[0066] Combination Figure 7 As shown, the measurement principle of the first laser sensor 36 in the upper contact rail measurement assembly is as follows:

[0067] The first laser sensor 36 scans at a 45-degree angle to the horizontal plane. The first laser sensor scans the contour of the contact rail and uploads the data to the laptop 4 via a network cable. The data processing software calculates the distance d using a mathematical model. The guide height h (the vertical distance from the top surface of the contact rail to the top surface of the adjacent running rail) is calculated as follows:

[0068] h = sd × cos45 = s - 0.707 × d

[0069] In the formula, s is the distance from the first laser sensor to the top surface of the running track, and this value is fixed after the measurement components are assembled.

[0070] The pull-out value 'a' (the shortest horizontal distance from the center of the contact rail to the inner side of the adjacent running rail) is calculated as follows:

[0071] a = b + c + g

[0072] Where b is a fixed value, determined after the components are assembled and remains unchanged. g is the distance from the center of the contact rail to the optical center of the first laser sensor, which can be obtained by analyzing the laser scanning line.

[0073] c = d × sin45 = 0.707 × d

[0074] Therefore, the output value a = 0.707 × d + b + g.

[0075] Furthermore, in another embodiment, such as Figure 1-2 As shown, the first measuring arm 7 of the comprehensive inspection instrument for contact rail, induction plate, and track static geometric parameters is detachably mounted on the left side of the traveling frame via a first connecting base 9. A screw hole is provided in the middle of the left side of the longitudinal beam 2 of the traveling frame, and the first connecting base 9 is bolted to the middle of the left side of the longitudinal beam 2, allowing for the installation of the contact rail measuring component as needed. Similarly, the second measuring arm 11 of the comprehensive inspection instrument for contact rail, induction plate, and track static geometric parameters is detachably mounted on the traveling frame via a second connecting base 13. A screw hole is provided in the middle of the crossbeam 1 of the traveling frame, and the second connecting base 13 is bolted to the upper side of the middle of the crossbeam 1, allowing for the installation of the induction plate measuring component as needed. Additionally, a push rod 3 is provided on the traveling frame, with a support plate on the push rod 3. The laptop computer 4 is mounted on the support plate. The push rod 3 is inclined, serving not only to support the laptop computer 4 but also to facilitate pushing the traveling frame along the track. The bottom of the push rod 3 is also detachably mounted on the crossbeam 1 via bolts, allowing for adjustment of the push rod 3's installation direction for easy pushing.

[0076] Furthermore, in another embodiment, such as Figure 1-4 As shown, the contact rail, induction plate, and track static geometric parameter comprehensive inspection instrument are equipped with handrails on both sides of the traveling frame and on the rear side of the support plate. Specifically, there is one handrail on the front and rear of the left side of the longitudinal beam 2, and one handrail at the bottom of the right side of the crossbeam, to facilitate moving the traveling frame. The handrail on the rear side of the support plate at the top of the push rod 3 is for the convenience of pushing the traveling frame.

[0077] Furthermore, in another embodiment, such as Figure 1 As shown, the battery module of the contact rail, induction plate, and track static geometric parameter comprehensive inspection instrument includes a first lithium battery module 8, a second lithium battery module 12, and a third lithium battery module. The first lithium battery module 8 and the second lithium battery module 12 are respectively mounted on the first measuring arm 7 and the second measuring arm 11. The first lithium battery module 8 is mainly used to power the first laser sensor 6 in the contact rail measurement assembly, and the second lithium battery module 12 is mainly used to power the second laser sensor 10 in the induction plate measurement assembly. The third lithium battery module is located in the gyroscope and data acquisition box 5. The third lithium battery module in the gyroscope and data acquisition box 5 supplies power to all sensors, the gyroscope, and the data acquisition board. That is to say, the three modules of contact rail measurement, induction plate measurement, and track geometric parameter measurement are independently powered, which is convenient for disassembly and assembly for individual use.

[0078] Based on the above embodiments, the comprehensive inspection instrument for contact rail, induction plate, and track static geometric parameters has the following advantages: it can simultaneously measure track static geometric parameters, contact rail parameters, and induction plate parameters. It is pushed along the track by a traveling frame, and continuous measurements are performed during this process, reducing the number of personnel required for on-track measurements, lowering labor intensity, and improving work efficiency. The contact rail measurement assembly and induction plate measurement assembly are detachable and can be selected according to site conditions, offering flexible usage. It is equipped with both lower and upper contact contact rail measurement assemblies, adaptable to measuring the geometric parameters of contact rails with different power supply methods. This comprehensive inspection instrument uses a laser sensor to achieve non-contact measurement of the contact rail and induction plate, resulting in high measurement accuracy.
