Problems solved by technology

The disadvantage is that the position of the blister tube 18B is maintained by the elastic force of the springs 18UB and 18LB. As time goes by, the springs 18UB and 18LB will relax and the elastic force will weaken, causing the position of the blister tube 18B to change and produce deviations.

Embodiment 1

[0049] Embodiment 1 of the leveling system of the laser leveling instrument of the present invention includes a vertical installation and debugging part, and the vertical installation and debugging part will be described in detail below:

[0050] Such as Figure 4 , Figure 5 as shown, Figure 4 It is a schematic diagram of the three-dimensional structure of Embodiment 1 of the leveling system of the laser leveling instrument of the present invention; Figure 5 for Figure 4 The front view along the X direction of the leveling system of the laser leveler shown in . The leveling system 10 of the laser leveling instrument of the present invention includes a rotating part 20, a main body 12, a vertical sensor part 15 and a bubble tube 15B. The rotating part 20 has a laser beam exit hole 30 along the axis of the rotating part 20 . The light exit hole 30 is used to emit a positioning laser beam.

[0051] The main body 12 is provided with a frame 15H having two side walls para...

Embodiment 2

[0071] Such as Figure 9 , Figure 10 , Figure 11 and Figure 12 as shown, Figure 9 It is the front view of Embodiment 2 of the leveling system of the laser leveling instrument of the present invention; Figure 10 for Figure 9 Enlarged view of part E in middle; Figure 11 for Figure 9 The enlarged and exploded view of part E in the middle; Figure 12 for Figure 9 C-C sectional view of part E in middle. The difference between the second embodiment and the first embodiment is only that the connection method between the adjustment seat 15T′ and the main body 12 is different. In the second embodiment, the upper end of the back plate 150 of the adjustment seat 15T' is connected to the fixed plate 12P' through a cylindrical pin 21. The axis of the cylindrical pin 21 is perpendicular to the axis of the bottom wall adjustment screw 18, that is, parallel to the Y axis direction. The specific structure is: the cylindrical pin 21 is arranged on the upper wall 152T' of the...

Embodiment 3

[0086] Such as Figure 13 , Figure 14 as shown, Figure 13 It is a three-dimensional structural schematic diagram of Embodiment 3 of the leveling system of the laser leveling instrument of the present invention; Figure 14 for Figure 13 The leveling system of the laser leveler shown in is viewed along the X direction. In addition to the vertical sensor part 15 in the first or second embodiment, the present invention also includes a horizontal installation and debugging part, which includes the first sensor part 14 and the second sensor part 13 .

[0087] The first sensor part 14 includes a first blister tube 14B, a first frame 14H, a photocell circuit board 14L and a light-emitting diode 14D; the second sensor part 13 includes a second blister tube 13B, a second frame 13H, a photocell circuit board and a light-emitting diode, And the structures of the second sensor part 13 and the second sensor part 14 are completely the same. Both the second frame 13H and the first fra...

Abstract

The invention discloses a leveling system of a laser leveling device and an adjusting method thereof. The leveling system comprises a main body and a bubble pipe, a frame is arranged on the main body, the bubble pipe is arranged on the frame, and the axis of the bubble pipe is parallel to the laser beam. The leveling system further comprises an adjusting base, the frame is arranged in the adjusting base, and the upper end of the adjusting base is connected with the main body in a rotary mode. The axis of the rotating axis between the upper end of a back plate and the main body is parallel to the back plate and is vertical to the laser beam, the bottom wall of the adjusting base is provided with a through axis vertical to the screwed hole on the bottom wall of the back plate, and the corresponding part of the main body is provided with a main body screwed hole. An adjusting barrel is arranged between the screwed hole on the bottom wall and the main body, an adjusting screw on the bottom wall passes through the screwed hole on the bottom wall and the through hole of the adjusting barrel and is connected with the screw of the main body screwed hole. The invention can effectively solve the positioning of the sensor components on different positions and ensure the accuracy of the positioning, reduce the installing and adjusting time, and enhance the production efficiency.

Description

technical field [0001] The invention relates to a leveling system of a laser leveling instrument applied in engineering survey and a method for debugging the leveling system. Background technique [0002] The laser leveling instrument is used to detect the levelness of engineering measurement. One of the main components of the laser leveling instrument is the leveling system, which includes rotating parts, supporting parts and sensors. During the use of the laser leveling instrument, the water bubble in the blister tube is mainly adjusted by adjusting the water bubble tube in the sensor, so as to ensure that the light emitted by the laser leveling instrument is horizontal or vertical. It can be seen that the assembly parallelism or perpendicularity of the blister tube in the sensor of the laser leveling instrument and the reference plane of the laser leveling instrument has a great influence on the use accuracy of the laser leveling instrument. Therefore, during the assemb...
