Referring to fig. 8 and 9 in combination, fig. 8 is a schematic structural diagram of the track parameter measuring scale 100 according to the present embodiment in practical application, and fig. 9 is a schematic sectional view of B-B in fig. 8.
In this embodiment, taking a measuring switch as an example, a measuring mode of the track parameter measuring scale 100 will be described. It can be understood that the first laser ranging module 121 and the second laser ranging module 131 each have a plurality of laser probe combinations, each of the laser probe combinations includes a transmitting probe and a receiving probe, and the first laser ranging module 121 and the second laser ranging module 131 can determine the working sidewall and measure the distance in multiple directions through respective combinations of the plurality of laser probes.
Specifically, the first laser ranging module 121 has a first reference line 1211 extending in the vertical direction, and the second laser ranging module 131 has a second reference line 1311 extending in the vertical direction. The first laser ranging module 121 is used for measuring a first horizontal distance between a working edge line on a working side wall of the first reference line 1211 near the second reference line 1311 and the first reference line 1211, and is also used for measuring a second horizontal distance between a working edge line on a working side wall of the first reference line 1211 far from the second reference line 1311 and the first reference line 1211.
The second laser ranging module 131 is used for measuring a third horizontal distance between the working edge on the working side wall of the second reference line 1311, which is far from the first reference line 1211, and the second reference line 1311, and is also used for measuring a fourth horizontal distance between the working edge on the working side wall of the second reference line 1311, which is near to the first reference line 1211, and the second reference line 1311, and is also used for measuring a fifth horizontal distance between the first reference line 1211 and the second reference line 1311.
In the switch structure shown in fig. 9, the first rail body is a combination of the center rail 210 and the wing rails 220, and the second rail body is a combination of the stock rail 230 and the guard rail 240. The cooperation of the sideslip measurement assembly 120 and the first rail body means that the tread of the first rail top wheel 123 is attached to the top wall of the head rail 210, and the first rail side wheel 124 and the first laser ranging module 121 are located between the head rail 210 and the wing rail 220. The engagement of the rotation-measuring assembly 130 with the second rail body means that the tread of the second rail head wheel 133 engages the top wall of the stock rail 230, and the second rail side wheel 134 and the second laser ranging module 131 are located between the stock rail 230 and the guard rail 240.
The first horizontal distance refers to a horizontal distance between the working edge on the working side wall of the wing rail 220 and the first reference line 1211, and the second horizontal distance refers to a horizontal distance between the working edge on the working side wall of the centrifugal rail 210 and the first reference line 1211. The third horizontal distance refers to the horizontal distance between the working edge line on the working side wall of the stock rail 230 and the second reference line 1311, and the fourth horizontal distance refers to the horizontal distance between the working edge line on the working side wall of the guard rail 240 and the second reference line 1311.
The working side line refers to a line formed by intersecting a horizontal plane 16mm downward from the top wall of the corresponding rail body with the working side wall. The working edge line of the wing rail 220 refers to a line formed by intersecting a horizontal plane of 16mm downward from the top wall of the core rail 210 with the working side wall of the wing rail 220, and the working edge line of the core rail 210 refers to a line formed by intersecting a horizontal plane of 16mm downward from the top wall of the core rail 210 with the working side wall of the core rail 210; the working edge line of the stock rail 230 refers to a line formed by intersecting a horizontal plane of 16mm downward from the top wall of the stock rail 230 with the working side wall of the stock rail 230, and the working edge line of the guard rail 240 refers to a line formed by intersecting a horizontal plane of 16mm downward from the top wall of the stock rail 230 with the working side wall of the guard rail 240.
In practical applications, after the data acquisition system 141 of the interaction module 140 acquires the first horizontal distance, the second horizontal distance, the third horizontal distance, the fourth horizontal distance and the fifth horizontal distance, the data processing system 142 selects a corresponding processing mode according to the user instruction received by the interaction system 149, so as to obtain a corresponding parameter.
The data processing system 142 can calculate the sum of the second horizontal distance, the third horizontal distance, the fifth horizontal distance and the first correction value to obtain the track gauge of the track to be measured. The corresponding calculation formula is: l (L) 1 ＝X 2 +X 3 +X 5 +P 1 Wherein L is 1 Characterization of track gauge, X 2 Characterizing a second horizontal distance, X 3 Characterizing a third horizontal distance, X 5 Characterizing a fifth horizontal distance, P 1 The first correction value is characterized.
It should be noted that, in the production process, there is an unavoidable error between the laser probe and the reference line, that is, there is a certain error between the second horizontal distance, the third horizontal distance and the fifth horizontal distance detected by the first laser ranging module 121, so the first correction value is pre-stored to participate in the data processing, so as to eliminate the errors of the second horizontal distance, the third horizontal distance and the fifth horizontal distance.
The data processing system 142 is further capable of calculating a second horizontal distance plus a fifth horizontal distance, subtracting the fourth horizontal distance, and adding the value of the second correction value to obtain a search interval of the track under test. The corresponding calculation formula is: l (L) 2 ＝X 2 +X 5 －X 4 +P 2 Wherein L is 2 Characterization of the audit interval, X 4 Characterizing the fourth horizontal distance, P 2 The second correction value is characterized. Similarly, the second correction value is a pre-stored value, so as to eliminate errors of the second horizontal distance, the fifth horizontal distance and the fourth horizontal distance.
The data processing system 142 can also calculate a fifth horizontal distance minus the first horizontal distance, minus the fourth horizontal distance, and adding the value of the third correction value to obtain the back guard distance of the track under test. The corresponding calculation formula is: l (L) 3 ＝X 5 －X 1 －X 4 +P 3 Wherein L is 3 Characterization of back-guard distance, X 1 Characterizing a first horizontal distance, P 3 And characterizing the third correction value. Similarly, the third correction value is a pre-stored value, so as to eliminate errors of the fifth horizontal distance, the first horizontal distance and the fourth horizontal distance.
Referring to fig. 10 in combination, fig. 10 is a schematic diagram showing the structure of the outer surface of the rail to be tested.
The interaction module 140 is further configured to detect an inclination angle of the main scale 110 relative to a horizontal plane in a state that the traversing measurement assembly 120 is matched with the first rail body and the rotation measurement assembly 130 is matched with the second rail body, and the interaction module 140 is further configured to calculate an outer height of the track to be measured according to the inclination angle.
In the state that the lateral movement measuring assembly 120 is matched with the first rail body and the rotation measuring assembly 130 is matched with the second rail body, the horizontal detecting member 143 can detect an inclination angle of the main scale 110 compared with a horizontal plane. The data processing module calculates the sine value of the inclination angle, and multiplies the obtained sine value by a pre-stored reference length to obtain the outer ultrahigh value. The calculation formula is as follows: μ=lsin a, where μ represents the outer super-height, L represents the reference length, and a represents the tilt angle.
The reference length refers to the distance between two points of action on the track to be measured with the wheel set, and is pre-stored according to industry standards, for example, a 1435mm gauge is typically 1506mm.
In practical application, the measuring staff holds the operating handle 150, spans the main scale 110 between the first rail body and the second rail body of the rail to be measured, and then buckles the wrench 151 according to the width of the rail to be measured to adjust the distance between the traversing measuring assembly 120 and the rotating measuring assembly 130, and makes the first rail top wheel 123 of the traversing measuring assembly 120 contact with the top wall of the first rail body, and the second rail top wheel 133 of the rotating measuring assembly 130 contacts with the top wall of the second rail body, so that the rail parameter measuring scale 100 is erected on the rail to be measured. The rail parameter measuring scale 100 is then pushed along the rail to be measured, and the first rail top wheel 123 and the second rail top wheel 133 roll.
In this process, the rotation measuring assembly 130 adaptively rotates according to the bending change of the track, and the traversing measuring assembly 120 adaptively slides according to the track width change, so as to ensure that the track parameter measuring ruler 100 is always precisely matched with the track to be measured, and avoid the state of repeatedly adjusting the track parameter measuring ruler 100. In this process, the first laser ranging module 121 and the second laser ranging module 131 acquire the detection data in real time, and the interaction module 140 processes the detection data in real time to acquire and display various parameters, and selectively send out or store the parameters according to the user instruction.
It can be seen that, the track parameter measuring ruler 100 provided in this embodiment adopts the laser ranging module to replace the traditional contact measuring ruler, which can avoid the problem of poor detection precision caused by abrasion of the detection reference, and the detection precision is higher. And, sideslip measurement subassembly 120 and rotatory measurement subassembly 130 can the self-adaptation be adjusted, can accomplish the measurement to multiple parameter simultaneously, do not need the state of manual adjustment dipperstick, remove the manual repetition and seek and judge minimum distance when measuring the gauge or looking up the interval, remove the manual repetition and seek and judge the maximum distance when measuring the back protection distance, promote measurement efficiency and measurement accuracy.
