[0002] The laser plumb line is an optical instrument that gives a plumb line based on the gravity line. It can be used to measure small horizontal deviations relative to the plumb line, transfer the point position of the plumb line, measure the vertical profile of an object, and transfer the vertical position. In order to ensure the reliability of the plumb line, the laser plumb line needs to be calibrated regularly. According to the regulations, the laser spot generated by the laser plumb line needs to be observed at 100 meters from the laser plumb line to calculate the deviation angle. The site requirements are high and the calibration is extremely inconvenient. Summary of the invention

[0003] The purpose of the utility model is to solve the above-mentioned problem and provide a laser plumb line calibration device which has low site requirements and is convenient for calibration.

[0004] The purpose of the utility model is achieved through the following technical scheme: a laser plumb line calibration device, including a placement table, a reflector, a collimator and a digital camera, the placement table and the reflector are alternately arranged in the vertical direction, and the collimator and the digital camera are horizontally arranged at the same height as the reflector.

[0005] Preferably, the placement table is arranged at an angle.

[0006] Preferably, a turntable is provided on the placement table.

[0007] Preferably, the placement table has an adjustable inclination.

[0008] Preferably, a mirror body is provided at the end of the reflective plate.

[0009] Preferably, the placing table and the reflecting plate are arranged on a lifting plate.

[0010] The beneficial effects of the utility model are: utilizing the characteristics of the collimator that it is sensitive to the incident angle of light and is not affected by the distance to reduce the requirement for the width of the site, and the calibration is convenient.

[0014] The technical solution of the utility model is further described below through embodiments and in conjunction with the accompanying drawings.

[0015] Embodiment 1:

[0016] This embodiment provides a laser plumb line calibration device, such as Figure 1 As shown, it includes a base 1, a vertical plate 2, a lifting plate 3, a placement platform 5, a reflector 4, a collimator 7 and a digital camera 8. The vertical plate 1 is vertically arranged on the base 1, a slide rail is arranged on the side of the vertical plate 2, the lifting plate 3 is slidably arranged on the vertical plate 2 through the slide rail, and two reflectors 4 and a placement platform 5 are alternately arranged on the lifting plate. The collimator and the digital camera are horizontally arranged at the same height as the reflector above.

[0017] In this embodiment, the placement table is tilted and the tilt angle is adjustable. The first end of the placement table is rotatably connected to the lifting plate, and a cable is provided at the second end of the placement table. The cable can be fixed at different heights of the lifting plate to adjust the tilt angle of the placement table. The tilted placement table can tilt the laser plummet 9 to detect the accuracy of the laser emitted in the tilted state. In addition, a turntable is also provided on the placement table, which is used to place the laser plummet to be measured and drive it to rotate.

[0018] A mirror body is provided at the end of the reflector plate 4, the mirror body is on the plumb line with the center of the turntable, and the mirror body is used to reflect or refract the light generated by the measured laser vertical meter to the parallel light tube, and the mirror body can be a plane mirror or a prism. In this embodiment, the mirror body is a pentaprism.

[0019] When calibrating the laser plumb line, first place the laser plumb line calibration device in Figure 1 In the state shown, the accuracy of the laser emitted upward by the laser plumb line under test is verified, and then the lifting plate is moved upward to make the reflective plate below parallel to the parallel light tube, and the accuracy of the laser emitted downward by the laser plumb line under test is verified.

[0020] Embodiment 2:

[0021] The present embodiment is a laser plumb line calibration device, which is different from the embodiment 1 in that: Figure 2 As shown, it includes a base 1, a vertical plate 2, a placement platform 5, a reflector 4, a collimator 7 and a digital camera 8. The vertical plate 1 is vertically arranged on the base 1, and two placement platforms 5 and a reflector 4 are alternately arranged on the vertical plate. The collimator and the digital camera are horizontally arranged at the same height.

[0022] When calibrating the laser plumb line instrument under test, first place the laser plumb line instrument under test on the placing table located below to calibrate the accuracy of the laser emitted upward by the laser plumb line instrument under test, and then place the laser plumb line instrument under test on the placing table located above to calibrate the accuracy of the laser emitted downward by the laser plumb line instrument under test.
