[0060] When the superelevation detection and calibration of the track gauge is performed, the superelevation measurement part of the track gauge is lowered and abutted against the first measuring platform 1, and the movable probe at the other end of the track gauge is abutted against the second measuring platform 2. The second measuring platform 2 drives the movable probe of the track gauge to move in the vertical direction, and the second measuring platform 2 can measure the vertical movement height of the movable probe of the track gauge. The superelevation detection and calibration of the track gauge can be completed by comparing the actual movement height of the movable probe of the track gauge measured by the second measuring platform 2 with the movement height of the movable probe displayed by the track gauge itself.

[0061] The first measuring platform 1 includes a first bracket 11, a first driving component 12, a first measuring component 13 and a first flat plate 14. The second measuring platform 2 includes a second bracket 21. The two ends of the track gauge are respectively against the first bracket 11 and the second bracket 21. The first bracket 11 is slidably arranged on the first flat plate 14. The first driving component 12 drives the first bracket 11 to slide horizontally on the first flat plate 14. The first measuring component 13 measures the sliding distance of the first bracket 11.

[0062] The first bracket 11 is slidably mounted on the first flat plate 14, and the second bracket 21 is mounted on the second measuring platform 2. When the track gauge is inspected and verified for length, the movable probes at both ends of the track gauge are respectively against the first bracket 11 of the first measuring platform 1 and the second bracket 21 of the second measuring platform 2, the first driving component 12 drives the first bracket 11 to slide horizontally on the first flat plate 14, the first measuring component 13 measures the horizontal movement distance of the movable probe of the track gauge along with the first bracket 11, and the movement distance measured by the first measuring component 13 is compared with the movement distance of the movable probe displayed by the track gauge itself, thereby completing the length inspection and verification of the track gauge.

[0063] The first driving component 12 includes a first motor 121, a first screw 122 and a first nut 123. The first motor 121 is installed on the first plate 14. The first motor 121 includes a first output shaft 124. The first output shaft 124 is installed in a horizontal direction. The first screw 122 is connected to one end of the first output shaft 124 and extends outward along the first output shaft 124. The first nut 123 is sleeved on the first screw 122 through an internal thread, and the first bracket 11 is connected to the first nut 123.

[0064] The first motor 121 is fixedly mounted on the first flat plate 14, one end of the first lead screw is connected to the first output shaft 124 through a coupling, the first nut 123 is sleeved on the first lead screw 122 through an internal thread, the first motor 121 drives the first lead screw 122 to rotate, and the first lead screw 122 drives the first nut 123 to move along the axis of the first lead screw 122 through threaded engagement. The rotor rotation angle of the first motor 121 is controlled by the host computer, and the pitch of the first lead screw 122 is known. The host computer controls the horizontal movement distance of the first bracket 11 through the first motor 121, the first lead screw 122 and the first nut 123.

[0065] The first measuring component 13 includes a first grating scale 131 and a first reading head 132. The first grating scale 131 is mounted on the first flat plate 14. The first reading head 132 is mounted on the first bracket 11. The first driving component 12 drives the first reading head 132 to move along an axial direction parallel to the first grating scale 131. The first reading head 132 measures the distance of relative movement with the first grating scale 131.

[0066] The first grating ruler 131 is fixedly mounted on the first flat plate 14, and the first grating ruler 131 is mounted along the horizontal movement direction of the first bracket 11. The first reading head 132 is fixedly mounted on the first bracket 11. When the first driving component 12 drives the first bracket 11 to move in the horizontal direction, the first bracket 11 drives the first reading head 132 to move in the direction parallel to the axis of the first grating ruler 131. During the movement of the first reading head 132, the distance between the detection part of the first reading head 132 and the grating ruler surface of the first grating ruler 131 remains unchanged. During the movement of the first bracket 11, the first reading head 132 moves in the direction parallel to the axis of the first grating ruler 131 and measures the distance of the first reading head 132 moving along the first grating ruler 131, thereby measuring the distance of the movable measuring head of the track gauge against the first bracket 11 moving in the horizontal direction.

[0067] The first bracket 11 and the second bracket 21 respectively include a standard measuring rod placement groove 3. Before the measurement begins, the two ends of the standard measuring rod are placed in the standard measuring rod placement groove 3 of the first bracket 11 and the second bracket 21 respectively, and the initial distance between the first measuring platform 1 and the second measuring platform 2 is adjusted according to the standard measuring rod.

[0068] The first bracket 11 and the second bracket 21 are respectively provided with standard measuring rod placement grooves 3 for placing the two ends of the standard measuring rod against the standard measuring rod placement grooves 3 of the first bracket 11 and the second bracket 21 before the first measuring platform 1 and the second measuring platform 2 perform length detection and superelevation detection and verification on the track gauge, and adjusting the horizontal distance between the first measuring platform 1 and the second measuring platform 2 to be the same as the length of the track gauge according to the standard measuring rod. After the horizontal distance adjustment is completed, the two ends of the special level ruler are respectively placed against the first bracket 11 and the second bracket 21, and the relative heights of the first bracket 11 and the second bracket 21 are adjusted to be consistent according to the special level ruler, and then the track gauge is subjected to length detection and verification and superelevation detection and verification.

[0069] like Figure 3 As shown, the second measuring platform 2 includes a second measuring component 23, a second driving component 22 and a second flat plate 24. The movable probe of the track gauge is against the second driving component 22. The second driving component 22 drives the movable probe to move in the vertical direction. The second measuring component 23 measures the distance the movable probe moves in the vertical direction.

[0070] When the superelevation detection and verification of the track gauge is performed, the superelevation measuring scale of the track gauge is pressed against the first measuring platform 1, and the movable probe of the track gauge is pressed against the second driving component 22. The second driving component 22 drives the movable probe of the track gauge to move in the vertical direction, and at the same time, the second measuring component 23 measures the distance that the movable probe moves in the vertical direction driven by the second driving component 22, and the result measured by the superelevation measuring scale of the track gauge is compared with the result measured by the second measuring component 23 to obtain the superelevation detection and verification result of the track gauge.

[0071] The second driving component 22 includes a second motor, a second lead screw 221, a second nut and a top frame 222. The second motor is installed on the second plate 24. The second motor includes a second output shaft, which is installed in the vertical direction. The second lead screw 221 is connected to the second output shaft and extends upward. The second nut is sleeved on the second lead screw 221 through an internal thread, and the top frame 222 is connected to the second nut.

[0072] When the track gauge is tested for superelevation, the superelevation measuring scale of the track gauge is placed against the first measuring platform 1, and the movable probe at the other end of the track gauge is placed against the top frame 222 of the second measuring platform 2. The top frame 222 is fixedly connected to the second nut, and the second motor drives the second lead screw 221 to rotate. The second nut is connected to the second lead screw 221 through a thread, and the rotational motion of the second motor is converted into a linear motion of the second nut moving along the axis of the second lead screw 221. The upper computer controls the rotation angle of the second motor rotor, and accurately controls the vertical movement distance of the top frame 222 through the second lead screw 221 and the second nut.

[0073] The second measuring component 23 includes a second grating scale 231 and a second reading head 232. The second grating scale 231 is mounted on the second plate 24. The second reading head 232 is mounted on the second driving component 22. The second driving component 22 drives the second reading head 232 to move along an axial direction parallel to the second grating scale 231. The second reading head 232 measures the distance of relative movement with the second grating scale 231.

[0074] When the track gauge is tested for superelevation, the second grating ruler 231 is fixedly mounted on the second flat plate 24, and the second reading head 232 is mounted on the top frame 222 of the second driving component 22. When the top frame 222 is driven by the second motor to move in the axial vertical direction of the second lead screw 221, the second reading head 232 follows the top frame 222 to move in the axial direction parallel to the second grating ruler 231, and the distance between the detection part of the second reading head 232 and the grating ruler surface of the second grating ruler 231 is always the same. The second reading head 232 moves in the axial direction parallel to the second grating ruler 231 and reads the distance the second reading head 232 moves along the second grating ruler 231, thereby measuring the distance the movable probe of the track gauge against the top frame 222 moves in the vertical direction.

[0075] The first measuring platform 1 and the second measuring platform 2 both include a horizontal adjustment component 4, and the horizontal adjustment component 4 is used to adjust the first measuring platform 1 and the second measuring platform 2 to a horizontal position, respectively.

[0076] Before the track gauge is inspected and calibrated for length and superelevation, the horizontal distance between the first measuring platform 1 and the second measuring platform 2 is adjusted using a standard measuring rod, and then the first plate 14 of the first measuring platform 1 and the second plate 24 of the second measuring platform 2 are adjusted horizontally. The horizontal adjustment component 4 measures the horizontality of the first plate 14 and the second plate 24 and sends it to the host computer. The host computer controls the horizontal adjustment component 4 to move according to the horizontality measured by the horizontal adjustment component 4, and the horizontal adjustment component 4 adjusts the horizontality of the first plate 14 and the second plate 24. After the adjustment is completed, the horizontal adjustment component 4 measures the horizontality of the first plate 14 and the second plate 24 again. After multiple rounds of measurement and adjustment, the horizontal leveling of the first plate 14 and the second plate 24 is finally completed.

[0077] The horizontal adjustment assembly 4 includes a two-dimensional electronic level 41 and at least three motor screw modules 42. The first measuring platform 1 includes a base 5 and a first plate 14. The second measuring platform 2 includes a base 5 and a second plate 24. The two-dimensional electronic level 41 is respectively installed on the first plate 14 and the second plate 24. The motor screw module 42 includes a third motor and a third screw. The third motor is installed on the base 5. The third motor includes a third output shaft. The third output shaft is installed in a vertical direction. The third screw is connected to the third output shaft and extends upward. The first plate 14 and the second plate 24 are respectively sleeved on the three third screws.

[0078] A two-dimensional electronic level 41 is installed on each of the first measuring platform 1 and the second measuring platform 2. Figure 3 As shown, taking the second measuring platform 2 as an example, the two-dimensional electronic level 41 installed on the second flat plate 24 detects the level of the second flat plate 24 and sends the level information to the host computer. After receiving the level information, the host computer determines whether it needs to be adjusted and how to adjust it, and then controls the three groups of motor screw modules 42 located at different positions below the second flat plate 24 to adjust the level of the second flat plate 24. The third output shaft of the third motor is installed in the vertical direction, and the third screw is connected to the third output shaft through a coupling. The second flat plate 24 is provided with a threaded hole, and the second flat plate 24 is sleeved on the third screw through the threaded hole. When the host computer controls the third motor to drive the third screw to rotate, the third screw drives the second flat plate 24 to change the vertical height of the sleeve joint of the third screw. The motor screw modules 42 located at different positions below the second flat plate 24 are adjusted separately to adjust the level of the second flat plate 24. After the motor screw module 42 is adjusted, the two-dimensional electronic level 41 measures the level of the second plate 24 again and sends the level information to the host computer. After judgment, the host computer drives the motor screw module 42 to operate until the level of the second plate 24 is adjusted to within the allowable range.
