Description

Technical Field

[0001] This invention relates to the technical field of track inspection instruments, and particularly to a track inspection instrument. Background Technology

[0002] To ensure the safe operation of trains and subways, the railway department has very strict requirements for track inspection. It must ensure the safety of the track and the accuracy of the measurement. When measuring the track, a track inspection instrument is used to monitor the track's geometric parameters and condition in real time.

[0003] However, existing T-type track inspection instruments typically use auxiliary sensors for track gauge and level measurement, and then synthesize and process the data to obtain the track gauge and level values. For existing T-type track inspection instruments measuring track gauge, please refer to... Figure 14 The measurable portion of the main track gauge is the main track gauge between the left-end measuring wheel 6 and the two right-end measuring wheels 8 at both ends of the side arm beam 7. The auxiliary track gauge portion on the right end is the track gauge from the midpoint of the line connecting the right-end measuring wheels 8 of the side arm beam to the right rail. The two are combined to obtain the track gauge. Since the two segments are combined, two sensors are required. Thus, the accuracy of the combined sensor signals is affected by the consistency of the fast response. Existing T-type track inspection instruments measure horizontal values ​​as follows: Since the main beam and side beam are fixedly connected, the horizontal sensor in the main beam actually measures the inclination angle of the three-point plane formed by the three rail-top measuring wheels on the top surface of the track. That is, the inclination angle of the three-point plane formed between the measuring wheel of the main beam away from the side beam and the two measuring wheels on the side beam. This inclination angle is calculated by trigonometric functions, and then the chord height of the rail on the side where the two rail-top measuring wheels on the side beam are located is calculated to obtain the combined horizontal value. The chord height of the side beam rail-top measuring wheel needs to be measured by another linear displacement sensor. Thus, the horizontal value is obtained by combining the data from the two sensors, and the accuracy is affected by the consistency of the fast response. Summary of the Invention

[0042] As shown in Figures 6-9As shown, the girder assembly 1 comprises a girder member 11, a first rail surface running wheel 12 and a first gauge measuring wheel 13 arranged on one end of the girder member 11, and left and right sliding units 14 which can slide transversely along the girder member 11 on the other end of the girder member 11; the left and right sliding units 14 comprise left and right sliding tables 142 which are slidingly connected with the girder member 11, a second rail surface running wheel 143 arranged on the left and right sliding tables 142, and a second gauge measuring wheel 144 arranged on the left and right sliding tables 142 through a connecting assembly, and at least one elastic member arranged between the left and right sliding tables 142 and the girder member 11;

[0043] Specifically, the girder member 11 is a cross beam with a hollow structure on the inner side; the left end of the girder member 11 is fixedly connected with the first rail surface running wheel 12 and the first gauge measuring wheel 13, and the first rail surface running wheel 12 and the first gauge measuring wheel 13 are both rotatable; when the rail detector is placed on the rail 5, the first rail surface running wheel 12 is in contact with the upper surface of the left rail 5, and the first gauge measuring wheel 13 is in contact with the inner side wall of the left rail 5; the right end of the girder member 11 is slidingly connected with the left and right sliding units 14, and the left and right sliding units 14 can slide transversely along the girder member 11; the left and right sliding units 14 comprise left and right sliding tables 142 which are slidingly connected with the girder member 11, and the second rail surface running wheel 143 and the second gauge measuring wheel 144 which are fixedly connected on the left and right sliding tables 142; in addition, the second rail surface running wheel 143 and the second gauge measuring wheel 144 are also rotatable;

[0044] As shown in Figure 13 the connecting assembly comprises a mounting bracket 1441 arranged on the left and right sliding tables 142, a sliding block 1443 which is slidingly connected with the mounting bracket 1441, and the second gauge measuring wheel 144 which is rotatably connected with the sliding block 1443, and a second elastic member arranged between the mounting bracket 1441 and the sliding block 1443; specifically, the mounting bracket 1441 is fixedly connected with the left and right sliding tables 142, and slide rods 1442 are fixedly connected on both sides of the interior of the mounting bracket 1441; the sliding block 1443 is slidingly connected on the two slide rods 1442, and the second gauge measuring wheel 144 is rotatably connected with the bottom of the sliding block 1443; the second elastic member is a first spring 1445, one end of which is fixedly connected with the mounting bracket 1441, and the other end of which is fixedly connected with the sliding block 1443;

[0045] As shown in Figure 5As shown, the measurement module includes a horizontal sensor 15 fixedly connected in the left side of the main beam member 11, a lower machine mainboard 16 fixedly connected in the right side of the main beam member 11, and a gauge sensor 17 connected with the second gauge measurement wheel 144. The gauge sensor 17 and the horizontal sensor 15 collect the geometric parameters of the track 5, and through the special track 5 measurement and analysis software of the notebook computer 4, the gauge, horizontal super-elevation, track direction, high-low, twist, triangular pit and other related parameters of the track 5 are measured and applied as digital engineering data.

[0046] When the track detector is placed on the track 5, the second rail surface running wheel 143 is in contact with the upper surface of the right track 5, and the second gauge measurement wheel 144 is in contact with the inner wall of the right track 5; the first elastic member is the second spring 146, and the number of the second spring 146 in the embodiment is four, two of which are located on the left and right sides of the left and right sliding tables 142. One end of the second spring 146 is fixedly connected with the main beam member 11, and the other end is fixedly connected with the left and right sliding tables 142. Thus, when the track detector is placed on the track 5, the first gauge measurement wheel 13 and the second gauge measurement wheel 144 can be abutted against the inner wall of the track 5, and the first rail surface running wheel 12 and the second rail surface running wheel 143 can be in close contact with the upper surface of the track 5 through the gravity of the track detector itself; the first rail surface running wheel 12 and the second rail surface running wheel 143 are on the same horizontal line, and the first gauge measurement wheel 13 and the second gauge measurement wheel 144 are also on the same horizontal line; when the first rail surface running wheel 12 and the second rail surface running wheel 143 are in contact with the surface of the track 5, the first gauge measurement wheel 13 and the second gauge measurement wheel 144 are located at 16 mm below the rail surface;

[0047] Further, when the track 5 is in a straight state, the first spring 1445 is in a slightly compressed state, and the second gauge measurement wheel 144 and the two side beam abutting wheels 224 are in contact with the inner wall of the track 5; when the track 5 is in a state of “ Figure 14 When the track 5 is in a state of “ Figure 14The first spring 1445 is reset from the compressed state, the first spring 1445 reset will drive the sliding block 1443 to move in the direction close to the track 5, the sliding block 1443 moves to drive the second track gauge measuring wheel 144, so that the second track gauge measuring wheel 144 can also abut against the inner wall of the track 5 when the track 5 is in the arc state, and the sliding block 1443 is connected with the measuring end of the track gauge sensor 17, the track gauge sensor 17 is a linear displacement sensor, so that the displacement signal of the second track gauge measuring wheel 144 is collected, and the track gauge value is obtained; Therefore, only one track gauge sensor 17 is needed, and the track gauge value of the track 5 can also be measured when the track 5 is in the arc state, compared with the prior art, the number of measured variables is reduced, there is no external interference term, the system is simple and stable; Similarly, when the track 5 is in the opposite state, that is, when the track is inwardly curved, the second track gauge measuring wheel 144 will also move in the direction close to the girder, so that the track gauge value when the track 5 is in the inwardly curved state is measured; Note: since the curve radius of the railway track is very large, generally more than several hundred meters, the displacement amount required for the second track gauge measuring wheel 144 to abut against the side beam of the side beam component is not large.

[0048] As shown in Figure 10 and Figure 11 , the side beam assembly 2 is slidably connected to the left and right sliding tables 142 and can vertically slide along the left and right sliding tables 142; the side beam assembly 2 is combined with the main beam assembly 1, so that the track detector as a whole has a T shape.

[0049] The side beam assembly 2 includes a floating platform 21 slidably connected to the left and right sliding tables 142, the floating platform 21 can vertically slide along the left and right sliding tables 142, a measuring element 215 provided on the floating platform 21, the measuring element 215 is a gyroscope sensor for measuring the track direction and height of the track, and a side beam unit 22 provided on the floating platform 21; the side beam unit 22 includes a side beam component 221 fixedly connected to the floating platform 21, side beam running wheels 223 and side beam abutting wheels 224 fixedly connected to both ends of the side beam component 221, the side beam running wheels 223 and the side beam abutting wheels 224 are rotatable, and the side beam running wheels 223 provided on both ends of the side beam component 221 are on the same horizontal line, and the side beam abutting wheels 224 provided on both ends of the side beam component 221 are also on the same horizontal line.

[0050] As shown in Figures 1-3 , the push rod assembly 3 is detachably connected to the main beam component 11, and the main beam assembly 1 and the side beam assembly 2 are driven to travel on the track 5 by pushing the push rod assembly 3, the specific structure of the push rod assembly 3 is the prior art, and will not be described in detail here;

[0051] As shown in Figures 1-3 , the computer is a notebook computer 4, which is detachably connected to the upper part of the push rod assembly 3;

[0052] In summary, when it is necessary to measure track 5, the operator first places the track inspection instrument on track 5. Figure 4 As shown, the first track travel wheel 12 contacts the left rail surface, the second track travel wheel 143 contacts the right rail surface, the first gauge measuring wheel 13 contacts the inner wall of the left rail, and the second gauge measuring wheel 144 abuts against the inner wall of the right rail through the tension of the first spring 1445 and the second spring 146; the side beam travel wheel 223 also contacts the right rail surface through the weight of the side beam assembly 2, and the side beam abutment wheel 224 also abuts against the inner wall of the right rail through the tension of the second spring 146. Thus, when the track inspection instrument is pushed, the wheel system on the side beam unit 22 travels closely against the right rail, and under the action of a certain tension of the second spring 146, it stably maintains a triangular measuring posture and travels along the track 5, thereby ensuring the correct measuring posture of the track inspection instrument; when After each wheel train contacts the track 5, the operator can push the track inspection instrument on the track 5 via the push rod assembly 3. Through the horizontal sensor 15, the vertical height difference between the left and right rails can be measured as the superelevation value at the measurement point on track 5, as well as the horizontal value for evaluating the levelness of track 5. The gauge sensor 17, connected to the second gauge measuring wheel 144, collects gauge data 16mm below the rail surface of the right rail. The measuring component 215 is fixedly connected to the floating platform 21, which can slide vertically along the left and right sliding tables 142. Therefore, the measuring component 215 and the main beam component 11 are in a state where they can move orthogonally. When the track inspection instrument moves on track 5, the measuring component 215 can detect the displacement in the orthogonal direction it generates, which is the relevant geometric parameter for detecting changes in track 5. This can be understood as... Figure 12 As shown, when the top surface of track 5 is concave in a non-linear state, the side beam unit 22 floats and rises relative to the main beam 11 in the vertical direction. Therefore, the side beam traveling wheels 223 at both ends are not aligned with the second track surface traveling wheel 143 in the middle. Similarly, the second track gauge measuring wheel 144 can also float and be offset from the side beam traveling wheels 223 at both ends of the side beam component to contact the track 5. The forward trajectory and vertical trajectory of track 5 are thus measured by the measuring element 215 on the floating platform 21, which yields the results. The corresponding elevation and alignment data of track 5 are obtained; the alignment and elevation data are used to evaluate the smoothness of track 5 in two directions. On the one hand, under the same track tension applied by the track inspection instrument, the side beam assembly 2 has a much smaller mass relative to the entire track inspection instrument, which can respond more quickly to the rails closely attached to track 5 and accurately reflect the measured track data. On the other hand, the mathematical model for track smoothness evaluation also needs to import track measurement values ​​such as mileage, gauge, and level. Therefore, improving the accuracy of gauge and level measurements is also beneficial to improving the alignment and elevation data.

[0053] In addition, the track detector of the application is placed on the track for measurement, the first rail surface running wheel 12 and the second rail surface running wheel 143 are in contact with the top surfaces of the two rails of the track 5, the horizontal sensor 15 on the main beam 11 directly measures the inclination angle between the two points of the left and right rails, and then the track detector software calculates the inclination angle by using the trigonometric function, and then the height difference between the left and right rails is obtained, that is, the super-elevation value and the horizontal value of the track 5 are obtained, and the super-elevation value and the horizontal value of the track 5 are obtained by the up-and-down floating side beam assembly 2 and the horizontal sensor 15. Compared with the prior art, the application reduces the horizontal sensor 15 for measuring the track horizontal value, and the measured variable value is less, and there is no external interference term, so that the system is simple and stable.

[0057] Specifically, two vertical guide shafts 212 are arranged in each of the two frame bodies 211, and the vertical guide shafts 212 and the sleeves 145 are protected by the frame bodies 211, so as to avoid the sleeves 145 and the vertical guide shafts 212 from being exposed to the outside and being impacted by the outside, thereby preventing the sliding accuracy of the vertical guide shafts 212 from being damaged and affecting the measurement of the measuring element 215. The measuring element 215 is fixedly connected to the installation plate 214 by bolts.

[0060] Further, as shown in Figure 9 and Figure 10 , the main beam member 11 is provided with a lower through hole 148 at the lower part thereof, and the floating platform 21 further comprises a lower baffle 216 arranged between the lower parts of the two frame bodies 211, and the lower baffle 216 is provided with a through hole 217 at the middle part thereof, and the second rail surface running wheel 143 is exposed through the lower through hole 148 and the through hole 217.
