Problems solved by technology

Since the vertical deformation of structural components is generally small and difficult to measure
Therefore, it is cumbersome to directly measure the deflection, and the measurement results are not accurate
[0003] In the prior art, a laser rangefinder is also used to measure the vertical deformation of the structure. By fixing the reflector on the vertical plane on the structure to be measured, the laser rangefinder irradiates the reflector before and after the deformation of the structure. The distances are different, and then the vertical deformation of the structure is calculated. This calculation needs to be converted by complex formulas, which also leads to low measurement accuracy.

Embodiment 2

[0032] The second specific embodiment of a vertical deformation measuring device of the present application, see image 3 As shown, the main technical solutions of this embodiment are the same as those of Embodiment 1, and the features not explained in this embodiment are explained in Embodiment 1, and will not be repeated here. The difference between this embodiment and Embodiment 1 is that the reflector 4 is arranged as a circular platform, which has an arc reflective surface 41 inclined at 45° relative to the horizontal plane, and is suitable for simultaneous measurement of vertical deformation from multiple directions. Only one reflector 4 needs to be set, and with the reflector 4 as the center, a plurality of range finders 3 are arranged in the circumferential direction, so that measurements can be made from multiple directions, and having multiple data parts can further improve the reliability of the measurement work.

[0034] The third specific embodiment of a vertical deformation measuring device of the present application, see Figure 4 As shown, the main technical solutions of this embodiment are the same as those of Embodiment 1, and the features not explained in this embodiment are explained in Embodiment 1, and will not be repeated here. The difference between this embodiment and Embodiment 1 is that the cross section of the reflector 4 is set in an isosceles trapezoidal shape, and it has two reflecting surfaces 41 inclined at 45° relative to the horizontal plane, which are suitable for simultaneous vertical deformation from two directions. Measurement, the isosceles trapezoid is easier to fix and install, and the hanging stability of the isosceles trapezoid is more stable.

Embodiment 4

[0036] For the fourth specific embodiment of a measuring device for vertical deformation of the present application, see Figure 5 As shown, the main technical solutions of this embodiment are the same as those of Embodiment 1, and the features not explained in this embodiment are explained in Embodiment 1, and will not be repeated here. The difference between this embodiment and Embodiment 1 is that the reflector 4 is conical and has an arc reflective surface 41 inclined at 45° relative to the horizontal plane, which is suitable for simultaneous measurement of vertical deformation from multiple directions. Only one reflector 4 needs to be provided, and a plurality of rangefinders 3 are arranged around the reflector 4 in the circumferential direction, so that measurements can be made from multiple directions, further improving work efficiency.

Abstract

This application relates to the technical field of measuring equipment, in particular to a measuring device for vertical deformation, including a range finder and a reflector, the reflector is provided with a reflective surface with an angle of 45° to the horizontal plane, and in working condition, the range finder emits The laser light parallel to the horizontal plane reaches the reflective surface. The deflection of the structure can be obtained by measuring the horizontal displacement of the reflective surface. In this application, since the included angle between the reflecting surface and the horizontal plane is 45 degrees, the value of the horizontal displacement reduced or increased by the rangefinder is the upward or downward deformation of the vertical deformation, which can be obtained intuitively and quickly Deformation amount of vertical deformation. The application has the characteristics of simple operation and high work efficiency.

Description

technical field [0001] The present application relates to the technical field of measuring equipment, in particular to a measuring device for vertical deformation. Background technique [0002] In the deflection detection of structural components, especially when measuring the vertical deformation of structures such as floors, beams, and bridge girders, measuring tools such as measuring rulers, distance meters, etc. are generally used to directly measure the vertical deformation of structural components. out of shape. Because the vertical deformation of structural components is generally small and difficult to measure. Therefore, it is cumbersome to measure the deflection directly, and the measurement result is inaccurate. [0003] In the prior art, a laser rangefinder is also used to measure the vertical deformation of the structure. By fixing the reflector on the vertical plane on the structure to be measured, the laser rangefinder irradiates the reflector before and aft...
