Description

Technical Field

[0001] The utility model relates to the technical field of track geometric parameter detection, and specifically relates to a gauge and level measuring device. Background Art

[0002] Dynamic detection of track geometry is an important means for the operation and maintenance guarantee of railway infrastructure, featuring high measurement efficiency and good repeatability. Gauge and level parameters are important indicators for dynamic detection of track geometric irregularities. When there is a large deviation between the measurement results of the dynamic detection system and the actual true values, it will lead to serious problems in the line and affect the normal operation of vehicles. Usually, the dynamic detection results of gauge and level parameters need to be verified by on-site static measurement. Therefore, a high-precision gauge and level static measurement device is required to calibrate the dynamic track geometric measurement equipment.

[0003] Existing gauge and level static measurement equipment such as the Amberg track inspection trolley and the Riyue Ming track inspection trolley all adopt wheel contact measurement. Often, due to uneven force on the equipment during personnel operation and equipment torsion, the measurement error is large. The track gauge measuring equipment mainly uses a front and rear sliding measuring end to find the gauge measurement point, with complex operation and large reading error, and neither can meet the gauge and level value traceability requirements of the dynamic track geometric monitoring equipment.

[0024] It should be noted that, without conflict, the embodiments in this application and the features in the embodiments can be combined with each other. The present utility model will be described in detail below with reference to the drawings and in combination with the embodiments.

[0025] For the convenience of understanding and description, the following description of the present utility model adopts the absolute position relationship. Without special explanation, the orientation word "up" represents Figure 1 the upper side direction in Figure 1 the lower side direction in Figure 1 the left side direction in Figure 1 the right side direction in Figure 1 the direction perpendicular to the paper surface of Figure 1 and pointing to the inner side of the paper surface, and the orientation word "back" represents the direction perpendicular to the paper surface of Figure 1 and pointing to the outer side of the paper surface.

Regarding the parameters such as the dimensions of the components therein, those skilled in the art can specifically determine them according to actual needs.

[0026] Such as Figure 1As shown, a gauge and level measuring device according to an embodiment of the present utility model includes a cross beam 3, a displacement sensor 4, an inclination sensor 8, and a control unit 15. The cross beam 3 extends substantially in the left-right direction. An active end probe 2 is provided at the left end of the cross beam 3, and a fixed end probe 9 is provided at the right end of the cross beam 3. The active end probe 2 can move left and right, while the fixed end probe 9 cannot move left and right. The displacement sensor 4 can measure the distance between the active end probe 2 and the displacement sensor 4 in the left-right direction, and the displacement sensor 4 can also send the information of the distance (an electrical signal containing the characteristics of the distance) to the control unit 15. The inclination sensor 8 can measure the angle between the extending direction of the cross beam 3 and the horizontal plane, and the inclination sensor 8 can also send the information of the angle (an electrical signal containing the characteristics of the angle) to the control unit 15.

[0027] The active end probe 2 is located below the left end of the cross beam 3, and the active end probe 2 is connected to the cross beam 3 through an active end probe seat 1. The fixed end probe 9 is located below the right end of the cross beam 3, and the fixed end probe 9 is connected to the cross beam 3 through a fixed end probe seat 10. The active end probe seat 1 and the fixed end probe seat 10 can be connected to the cross beam 3 (bolt holes reserved in the preliminary design) through bolts.

[0028] The active end probe seat 1 is used to provide stable support for the active end probe 2. The active end probe 2 is mainly used for the disassembly and installation of the gauge and level measuring device on the rail 14 to be measured, so that the outer side surface of the active end probe 2 is in full contact with the action edge of the stock rail. The fixed end probe seat 10 provides a stable structural support for the following contact indicator light 11 and the fixed end probe 9.

[0029] The displacement sensor 4 can adopt an existing high-precision laser displacement sensor. The displacement sensor 4 is fixed to the left side of the lower surface of the cross beam 3 through bolts. The active end probe 2 and the displacement sensor 4 are arranged at intervals left and right, and the measuring end of the displacement sensor 4 faces the active end probe 2.

[0030] The displacement sensor 4 mainly realizes the acquisition of track geometric gauge data through the displacement change of the active end probe 2. The gauge and level measuring device adopts a non-contact measurement method, reducing the wear of the traditional gauge head, reducing the uncertainty of the traditional gauge measurement error, and improving the accuracy of gauge measurement.

[0031] As Figure 3 shown, the gauge and level measuring device further includes a battery 6. The battery 6 can adopt an existing lithium battery. The function of the battery 6 is to supply power to the control unit 15, the displacement sensor 4, the inclination sensor 8, and the following contact indicator light 11, etc. Along the left-right direction, the battery 6 is fixed to the middle of the lower surface of the cross beam 3 through bolts, and the control unit 15 is connected to the battery 6. The battery 6 can meet the requirements of high endurance and convenient carrying.

[0032] The displacement sensor 4 and the inclination sensor 8 are connected to the control unit 15 through signal lines, and the control unit 15 and the following contact indicator lamp 11 are connected to the battery 6 through power lines. The control unit 15 is used to receive, process, and analyze measurement data and output measurement results.

[0033] A groove is provided inside the cross beam 3. The opening of the groove faces upward, and the groove extends in the left-right direction. The extending direction of the groove is the same as that of the cross beam 3. The power line and the signal line are fixed in the groove of the cross beam 3 through cable ties. The cross beam 3 is made of magnesium-aluminum 6061 alloy material. The groove provided inside the cross beam 3 improves rigidity and has the advantages of being lightweight, not easily deformed, and convenient to carry. At the same time, it is convenient for the installation of various components and is mainly used to provide mechanical structure support for other components.

[0034] As Figure 1 and Figure 2 shown, the fixed-end probe 9 is an upright cylindrical structure. The fixed-end probe 9 is made of metal. Two fixed-end probes 9 are arranged at intervals front and back and are mirror images of each other. The distances from the fixed-end probe 9 to the two fixed-end probes 9 are the same. The fixed-end probe 9 can be connected and fixed to the fixed-end probe seat 10 through screws.

[0035] As Figure 1 and Figure 4 shown, the gauge and level measuring device further includes a contact indicator lamp 11. One pole of the battery 6 is connected to one fixed-end probe 9 through the first wire 12, and the other pole of the battery 6, the contact indicator lamp 11, and the other fixed-end probe 9 are connected in series in sequence through the second wire 13. Only when both fixed-end probes 9 are in contact with the rail 14, a closed circuit is formed, and the contact indicator lamp 11 can be lit. The contact indicator lamp 11 is mainly provided to ensure that both fixed-end probes 9 can be in full contact with the rail 14 during measurement, thereby improving the stability of measurement.

[0036] Both fixed-end probes 9 are fixed to the left side surface of the fixed-end probe seat 10, and the contact indicator lamp 11 is fixed to the front side surface or the rear side surface of the fixed-end probe seat 10. The number of fixed-end probes 9 is changed from one to two. Correspondingly, the measurement method is changed from the original two-point positioning method to the triangular clamping point method. One more fixed-end probe 9 is added, and the fixed-end probe 9 is made of metal material, reducing the wear of the probe during long-term use, improving the stability and accuracy of measurement, and reducing the error caused by manual measurement.

[0037] The gauge and level measuring device may further include a PC all-in-one machine 5. The PC all-in-one machine 5 can adopt existing technology products. The PC all-in-one machine 5 is fixed to the left side of the upper surface of the cross beam 3 through bolts. The control unit 15 is a part of the PC all-in-one machine 5. The PC all-in-one machine 5 includes a display unit and a storage unit.

[0038] The all-in-one PC 5 contains special measurement software, which can realize on-site calibration of the gauge and level measuring device, and can receive, process and analyze measurement data and output measurement results in real time. That is, the display unit of the all-in-one PC 5 can display the measurement information of the displacement sensor 4 and the inclination sensor 8.

[0039] The gauge and level measuring device further includes a handle 7. Along the left-right direction, the handle 7 is fixed to the middle of the upper surface of the cross beam 3 by bolts.

The trigger 16 can drive the movable end probe 2 to move to the right, and the movable end probe 2 can automatically reset after moving to the right.

[0040] The content of "the trigger 16 can drive the movable end probe 2 to move to the right, and the movable end probe 2 can automatically reset after moving to the right" can refer to the Chinese utility model patent CN208847091U, with the publication date of May 10, 2019, and the published "A self-restoring transmission device with articulated adjustment". The cooperation of the trigger 16 and the handle 7 can facilitate the disassembly and installation of the gauge and level measuring device on the rail 14 to be measured.

[0041] The inclination sensor 8 can adopt an existing high-precision inclination sensor to measure the geometric level data of the track through temperature compensation, improving the inclination measurement accuracy. The inclination sensor 8 is fixed to the right side of the upper surface of the cross beam 3 by bolts. The all-in-one PC 5 is located on the left side of the handle 7, and the inclination sensor 8 is located on the right side of the handle 7. Along the left-right direction, the distance from the inclination sensor 8 to the handle 7 is less than the distance from the inclination sensor 8 to the fixed end probe 9.

[0042] The working method of the gauge and level measuring device is introduced below.

[0043] First step: Before use, it is necessary to check whether the state of the gauge and level measuring device is good, whether the cross beam 3 is firm, and whether it is within the calibration validity period. In addition, it is also necessary to check the track state of the rail 14 to be measured to ensure that there are no sundries or damages affecting the measurement accuracy.

[0044] Second step: Turn on the power switch of the battery 6, operate the all-in-one PC 5 to run the measurement software, calibrate the displacement sensor 4 and the inclination sensor 8, and start measurement after the sensors are calibrated qualified.

[0045] Third step: Place the gauge and level measuring device on the rail 14, as Figure 5 shown, make the right ends of the two fixed end probes 9 fully contact with the working edge of the right rail 14, and make the left end of the movable end probe 2 fully contact with the working edge of the left rail 14. Start measurement after the contact indicator light 11 lights up.

[0046] Step 4: The gauge is equal to the initial distance between the left end of the movable probe 2 and the right end of the fixed probe 9 minus the transformation distance of the movable probe 2. The transformation distance of the movable probe 2 can be measured by the displacement sensor 4, and the track inclination angle is measured by the inclination sensor 8. Record the measurement results and take the average value of multiple measurements to improve the measurement accuracy.

[0047] As described above, only the specific embodiments of the present invention are provided, and the scope of implementation of the invention cannot be limited by them.
