[0027]
[0028] Where, L 1 It is represented as the verticality error of the elevator guide rail where the first magnetic fixing plate is located;
[0029] By performing difference calculation on the two first four-quadrant detectors and the second four-quadrant detectors, the gauge of the two elevator guide rails can be calculated. The calculation formula is:
[0030]

The combination of the second right angle prism 101 and the beam splitter prism 102 can realize the splitting of the collimated light beam into the first collimated light beam 20 and the second collimated light beam 21.
[0056] In one embodiment of the present invention, the first magnetic fixing plate 12 and the second magnetic fixing plate 13 are magnetic, and the first magnetic fixing plate 12 and the second magnetic fixing plate 13 can be magnetically attracted to the corresponding elevator guide rail, so as to facilitate adjusting the positions of the first magnetic fixing plate 12 and the second magnetic fixing plate 13 on the corresponding elevator guide rail during installation and debugging.
[0057] In one embodiment of the present invention, the first magnetic fixing plate 12 and the second magnetic fixing plate 13 are both perpendicular to the corresponding elevator guide rails or parallel to the ground.
[0058] In one embodiment of the present invention, the two guide rail moving units 11 are on the same horizontal plane; the first magnetic fixing plate 12 and the second magnetic fixing plate 13 are on the same horizontal plane, and the first four-quadrant detector 122, the second four-quadrant detector 131 and the collimated laser 121 are on the same horizontal plane.
[0059] Furthermore, the receiving ends of the first four-quadrant detector 122 and the second four-quadrant detector 131 are on the same horizontal plane as the output end of the collimating laser 121 .
[0060] In one embodiment of the present invention, the guide rail moving unit 11 is a guide rail climbing robot.
[0061] In one embodiment of the present invention, the guide rail moving unit 11 is a magnetic climbing robot or a magnetic adsorption wall climbing robot.
[0062] In one embodiment of the present invention, the ratio of the spot radius of the light beam emitted by the collimated laser 121 to the photosensitivity radius of the first four-quadrant detector 122 and the second four-quadrant detector 131 is 1:2, which can take into account both the measurement range and the measurement sensitivity.
[0063] The method for using the laser-aligned elevator guide rail verticality and track gauge rapid measurement device comprises the following steps:
[0064] 1) The first magnetic fixing plate 12 and the second magnetic fixing plate 13 are respectively adsorbed on the top or end of the corresponding elevator guide rail 10, and the horizontal heights of the first magnetic fixing plate 12 and the second magnetic fixing plate 13 are kept consistent; the two guide rail moving units 11 are respectively installed on the corresponding elevator guide rail 10; the horizontal heights of the two guide rail moving units 11 are kept consistent;
[0065] 2) After the first magnetic fixing plate 12 and the second magnetic fixing plate 13 are installed on the corresponding elevator guide rail 10, the collimated laser 121 is leveled so that the collimated light beam emitted by the collimated laser 121 is perpendicular to the ground, which is used as a measurement reference for the verticality of the guide rail. The spot centers of the first collimated light beam 20 and the second collimated light beam 21 are adjusted to coincide with the center of the first four-quadrant detector 122, and the spot center of the second collimated light beam 21 is adjusted to coincide with the center of the second four-quadrant detector 131;
[0066] 3) The collimated laser 121 on the first magnetic fixing plate 12 emits a collimated light beam to the combined beam splitter prism 111. When the collimated light beam passes through the combined beam splitter prism 111, the collimated light beam is split into a first collimated light beam 20 and a second collimated light beam 21. The first collimated light beam 20 is received by the first four-quadrant detector 122, and the two guide rail moving units 11 are started to move synchronously and at a constant speed, and the moving distance of the light spot of the first collimated light beam 20 measured by the first four-quadrant detector 122 on its surface is recorded;
[0067] 4) When measuring the verticality of another elevator guide rail 10, the first magnetic fixing plate 12 and the second magnetic fixing plate 13 are installed on the corresponding elevator guide rail 10 in a swapped manner, and the two guide rail moving units 11 are also installed on the corresponding elevator guide rail 10 in a swapped manner, and steps 2) and 3) are repeated;
[0068] 5) According to the measurement principle of the four-quadrant detector for the collimated light spot, the formula for calculating Δ as the total movement change of the light spot of the first collimated light beam 20 on the first four-quadrant detector 122 is:
[0069]
[0070] Wherein, Δ is the total movement change of the spot of the first collimated light beam 20 on the first four-quadrant detector 122, and U i is the voltage of each quadrant; k is the conversion coefficient;
[0071] According to the characteristic that the combined dichroic prism can magnify the verticality measurement value of the guide rail by two times, the verticality error of the elevator guide rail 10 is calculated, and the calculation formula is:
[0072]
[0073] Where, L 1 It is represented as the verticality error of the elevator guide rail 10 where the first magnetic fixing plate 12 is located;
[0074] By performing difference calculation on the two first four-quadrant detectors 122 and the second four-quadrant detector 131, the gauges of the two rows of elevator guide rails can be calculated, and the calculation formula is:
[0075]
[0076] Where D represents the gauge of the two elevator rails, Δ 11 represents the change in the spot position of the first collimated light beam 20 on the first four-quadrant detector 122, Δ 22 It represents the change in the spot position of the second collimated light beam 21 on the second four-quadrant detector 131.
[0077] In one embodiment of the present invention, in step 3) and step 4) of measuring the elevator guide rail, the principle diagram is as follows: Figure 2 In an ideal state, the elevator guide rail 10 is in a vertical state. When the guide rail moving unit 11 drives the combined beam splitter prism to move linearly along the elevator guide rail, the spot position of the first collimated light beam 20 will not move on the first four-quadrant detector 122. In reality, due to factors such as the installation error of the elevator guide rail, the elevator guide rail 10 is no longer in a vertical state. Figure 2The dotted line indicates the state where the elevator rail is not vertical. When the rail moving unit 11 drives the combined beam splitter prism 111 to move from the solid line position to the dotted line position, based on the laser collimation principle, the spot of the first collimated light beam 20 will move on the first four-quadrant detector 122, and the movement change can be expressed as Δ 1 According to the measurement principle of the four-quadrant detector for collimated light spots, when the center of the light spot deviates from the center of the detector, the light spot energy obtained by each quadrant will change accordingly. Therefore, the relative displacement of the light spot on the four-quadrant detector can be solved based on the energy change difference obtained by the detector.
[0078]
[0079] Wherein, Δ is the total movement change of the spot of the first collimated light beam 20 on the first four-quadrant detector 122, and E i is the voltage of each quadrant; k is the conversion coefficient (sensitivity).
[0080] Therefore, according to the characteristic that the combined dichroic prism can amplify the verticality measurement value of the guide rail by two times, the verticality error of the elevator guide rail 10 can be calculated, and the calculation formula is:
[0081]
[0082] Where, L 1 It is represented by the verticality error of the elevator guide rail 10 where the first magnetic fixing plate 12 is located.
[0083] Similarly, in order to measure the verticality error of another elevator guide rail, the first magnetic fixing plate 12 and the second magnetic fixing plate 13 are installed on the corresponding elevator guide rail 10 in a swapped manner, and the two guide rail moving units 11 are also installed on the corresponding elevator guide rail 10 in a swapped manner, so that the verticality error can be measured.
[0084] The principle of measuring the gauge of two elevator guide rails is as follows: Figure 4 As shown. Ideally, the two columns of guide rails are in a parallel vertical state, and the spot centers of the first collimated light beam 20 and the second collimated light beam 21 are adjusted to coincide with the center of the first four-quadrant detector 122, and the spot center of the second collimated light beam 21 coincides with the center of the second four-quadrant detector 131. At this time, no matter how the two guide rail moving units 11 move synchronously and at a constant speed on the guide rails, their light spots will not change position on the four-quadrant detector. However, when the elevator guide rail where the second magnetic fixing plate 13 is located is no longer in a vertical state, that is, at different positions, the track gauges of the two columns of elevator guide rails will change. Figure 3The dotted line indicates that the elevator rail where the second magnetic fixing plate 13 is located is not vertical. When the two rail moving units 11 move from the solid line position to the dotted line position at the same time, the spot of the second collimated beam 21 will change position on the second four-quadrant detector 131, and the change amount can be expressed as Δ 2
[0085] By performing difference calculation on the two first four-quadrant detectors 122 and the second four-quadrant detector 131, the gauges of the two rows of elevator guide rails can be calculated, and the calculation formula is:
[0086]
[0087] Where D represents the gauge of the two elevator rails, Δ 11 represents the change in the spot position of the first collimated light beam 20 on the first four-quadrant detector 122, Δ 22 It represents the change in the spot position of the second collimated light beam 21 on the second four-quadrant detector 131.
[0088] The above generally describes the present invention in detail, but it is obvious to a person skilled in the art that some modifications or improvements can be made to the present invention. Therefore, modifications or improvements that do not depart from the spirit of the present invention are within the scope of protection of the present invention.

The first collimated light beam is received by the first four-quadrant detector, and the two guide rail moving units are started to move synchronously and at a constant speed, and the moving distance of the light spot of the first collimated light beam measured by the first four-quadrant detector on its surface is recorded; 4) When measuring the verticality of another elevator guide rail, the first magnetic fixing plate and the second magnetic fixing plate are installed on the corresponding elevator guide rail in a swapped manner, and the two guide rail moving units are also installed on the corresponding elevator guide rail in a swapped manner, and steps 2) and 3) are repeated; 5) According to the measurement principle of the four-quadrant detector for the collimated light spot, the formula for calculating Δ as the total movement change of the light spot of the first collimated light beam on the first four-quadrant detector is: Where Δ is the total movement change of the spot of the first collimated beam on the first four-quadrant detector, U i is the output voltage for each quadrant; k is the conversion coefficient; According to the characteristic that the combined beam splitter can magnify the verticality measurement value of the guide rail by two times, the verticality error of the elevator guide rail is calculated, and the calculation formula is: Wherein, L1 represents the verticality error of the elevator guide rail where the first magnetic fixing plate is located; By performing difference calculation on the two first four-quadrant detectors and the second four-quadrant detectors, the gauge of the two elevator guide rails can be calculated. The calculation formula is: Where D represents the gauge of the two elevator rails, Δ 11 represents the change in the spot position of the first collimated beam on the first four-quadrant detector, Δ 22 It represents the change in the spot position of the second collimated light beam on the second four-quadrant detector.
