Problems solved by technology

[0002] In the construction process of the construction site, it is often necessary to carry out level measurement, and in the process of level measurement, the error of level measurement is often caused by environmental factors or installation factors, and now the level calibration often uses a heavy hammer, but the heavy hammer It often takes up a lot of space in the vertical direction, which is not conducive to the measurement of surface level. In addition, it takes a long time to calibrate, is greatly affected by wind or other factors, and has a large volume

Embodiment 1

[0030] Such as figure 1 As shown, the present invention discloses a horizontal detector of a cross-shaped tower base, which includes four tubes 2 connected end to end to form a quadrangle. The tubes 2 are filled with transparent liquid, and a mapping plate is arranged at a corner of the quadrangle. 7 and the laser 1, and reflectors 4 are set at the other three corners, the laser 1 faces the reflector 4, the mapping plate 7 is located on the side of the laser 1, and the laser is projected to the map after being totally reflected by the three reflectors 4 and at least one liquid surface on board 7.

[0031] Below the pipe body 2 is provided with a cross-shaped mounting frame 9, and the four arms of the mounting frame 9 are respectively provided with an alignment measuring mechanism, which is used for the alignment of the points to be measured, and the alignment between the pipe body 2 and the point to be measured. Determination of distance between points.

[0032] The alignmen...

Embodiment 2

[0038] Based on the level detector in embodiment 1, the automatic level debugging method of the controller:

[0039] Step 1: Place the tube body 2 horizontally, turn on the laser 1, the laser is reflected by the first mirror 4 after the first total reflection of the liquid surface, and the reflected laser is reflected by the second mirror 4 after the second total reflection of the liquid surface The reflector 4 reflects, and the laser reflected again is reflected by the third reflector 4 after the third total reflection of the liquid surface, and then the laser is projected onto the mapping plate 7 after the third total reflection of the liquid surface;

[0040] Step 2: The light sensor on the mapping board 7 sends a signal to the controller after being irradiated by the laser; when the light sensor sending the signal to the controller is not the light sensor at the specified position, the controller The relative position of the sensor is controlled by the displacement mechani...

Embodiment 3

[0042] Based on the level detector in embodiment 1, the method for measuring the level of the cross-shaped tower base:

[0043]Step 1: Adjust the struts 8 on the four arms of the installation frame 9 to the same height, adjust the position of the carriage, make the lower end of the struts 8 align with the installation point of the tower base, and make the liquid in the pipe body 2 flow freely ;

[0044] Step 2: Turn on the laser 1, so that the laser is projected onto the mapping plate 7 through three reflections of the mirror 4 and four reflections of the liquid surface, and gradually adjust the height of the support rod 8 through the lifter 6, so that the laser emitted by the laser 1 is reflected After pointing to the specified position of the mapping board 7;

[0045] Step 3: According to the height difference of the struts 8 on the four arms of the installation frame 9, judge whether the tower base is level and its deflection amount.

Abstract

The invention relates to the field of building construction, in particular to a horizontal detector for a cross-shaped tower foundation. The horizontal detector comprises four pipes which are in end-to-end connection to form a quadrangle, the pipes are filled with transparent liquid, a mapping plate and a laser are arranged at one corner of the quadrangle, reflectors are arranged at the other three corners, the laser faces the reflectors, the mapping plate is positioned on the lateral side of the laser, and laser is totally reflected by the three reflectors and liquid surface for at least once and then projected to the mapping plate. The horizontal detector is accurate and quick in horizontal detection of the cross-shaped tower foundation, and by means of liquid surface total reflection and mirror reflection, measurement accuracy is improved, and levelness can be measured quickly and efficiently.
