Detailed Description
The following are specific embodiments of the present invention and are further described with reference to the drawings, but the present invention is not limited to these embodiments.
As shown in fig. 1 and fig. 2, the detecting instrument includes a strip-shaped box body 1, the upper end of the box body 1 is provided with a first optical sensor 21, a light source is fixed on a mounting plate 22, the mounting plate 22 is hinged on the box body 1, the lower end of the mounting plate 22 is provided with a balancing weight 23, the upper end of the mounting plate 22 is provided with a first light beam source 24, and a reflection channel arranged in the box body 1 is arranged between the first light beam source 24 and the first optical sensor 21; in the vertical state of the box body 1, the reflection channel transmits the light of the energy of the first light beam source 24 to the first light sensor 21; the reflection channel comprises a plurality of first reflection assemblies and second reflection assemblies, the first reflection assemblies and the second reflection assemblies are distributed at intervals, the first reflection assemblies comprise two first reflection mirrors 25 which are parallel to each other, the first reflection mirrors 25 form an inclination angle with the horizontal plane, the second reflection assemblies comprise two second reflection mirrors 26 which are parallel to each other, and the inclination angle between the second reflection mirrors 26 and the horizontal plane and the inclination angle between the first reflection mirrors 25 and the horizontal plane are complementary angles; a shading plate 27 fixed on the box body 1 is arranged between the adjacent first reflection assembly and the second emission assembly; one side of the box 1 has a guide groove 11 for cooperation with a guide rail of an elevator.
The setting of balancing weight can ensure that first light beam source launches the initial mode and is vertical upwards all the time. The first reflection group and the second emission group are used for prolonging the beam path of the first beam source 24, so that the path of the first beam source 24 is prolonged, and the first purpose is that the size of the box body 1 can be reduced, if the size of the box body 1 is too large, when the guide groove 11 is matched with an elevator guide rail, if a guide rail deformation part exists, the box body 1 cannot normally pass through, and the gap of the guide groove 11 is increased, so that the detection precision is reduced; second, by extending the path of the light beam and providing the light shielding plate 27 between the first reflecting assembly and the second reflecting assembly, in a state where only the case 1 is vertically positioned, or within a small deviation from the longitudinal straight line, the light of the first light beam source 24 can reach the first light sensor 21 by reflection, the first light sensor 21 has a circular sensing range with extremely small dimensions, when the deviation angle is out of the range, the position of the first light sensor 21 cannot be reached due to the influence of the light shielding plate 27, and in fact, in the deviated state, the light beam passing between the first reflection set or the second reflection set is not horizontal, the infusion between the first reflection group and the second reflection group is not longitudinal, after multiple reflections, the inclination angle is amplified and finally cannot reach the position of the first optical sensor 21, and the detection accuracy can be greatly improved in this way.
In fact, the small size of the box 1 also improves the detection accuracy.
The lower end of the mounting plate 22 is provided with a second light beam source 31 capable of generating a light beam in the direction opposite to the emitting direction of the first light beam source 24, the lower end of the box body 1 is provided with a second light sensor 32 and a third light sensor 33, and the second light sensor 32 and the third light sensor 33 are respectively positioned on two sides of a vertical plane on which the hinge axis of the mounting plate 22 is positioned. In order to judge the deformation state of the deformation part, namely, which side deviates from the vertical direction when the box body 1 is positioned at the deformation part of the elevator track, the second light beam source 31 is arranged at the lower end of the box body 1, and when the first light sensor 21 does not detect the deformation state, the second light sensor 32 or the third light sensor 33 can detect the light beam emitted by the second light beam source 31, so that the deformation direction of the elevator track is judged, and the correction is convenient.
