Description

Technical Field

[0001] The utility model relates to the technical field of geological engineering surveying and mapping instrument parts, and more specifically to a positioning device for geological engineering surveying and mapping instruments. Background Art

[0002] In the process of geological engineering surveying and mapping, common surveying and mapping instruments include total stations, levels, theodolites, etc. Total stations are suitable for precise measurement and positioning. They are generally supported by tripods and placed at different surveying and mapping locations. After the total station has been used for a period of time, the prism base of the total station needs to be positioned to ensure the stability and reliability of its surveying and mapping.

[0003] During actual use, the prism base of the total station will have a centering deviation. There is no corresponding positioning device designed in the prior art, which makes the adjustment and positioning of the prism base inaccurate and the adjustment and positioning efficiency low, affecting the subsequent surveying and mapping effects.

[0017] In order to make the technical means, creative features, objectives and effects achieved by the utility model easy to understand, the utility model is further explained below with reference to specific diagrams.

[0018] In order to solve the problem that the adjustment and positioning of the prism base of the existing surveying and mapping instrument total station is not accurate enough, the adjustment and positioning efficiency is low, and the subsequent surveying and mapping effect is affected, such as Figure 1 and Figure 2 As shown, the present application includes a base 1, a leveling seat 2 is arranged above the base 1, leveling screws 3 are arranged around the leveling seat 2 and between the base 1, the leveling screws 3 pass through the surface of the leveling seat 2 and the leveling screws 3 are located between the leveling seat 2 and the base 1, and an adjusting nut 4 is arranged on the rod body, a positioning plate 8 is arranged in the middle area of ​​the leveling seat 2, and both sides of the leveling seat 2 are provided with mounting plates 5 with symmetrical structures, wherein a universal level 7 is arranged on the surface of one side of the mounting plate 5 and a compass 6 is embedded and installed on the surface of the other side of the mounting plate 5;

[0019] like Figure 3 As shown, a cross bracket 9 is provided inside the positioning plate 8, and scale bars 10 are processed on both side edges of the four bracket rods of the cross bracket 9;

[0020] Specifically, the method for adjusting and positioning the deviation in the prism base of the surveying and mapping instrument total station using the positioning device of the present application is as follows:

[0021] Step 1: Place the base 1 on the ground in the middle area below the tripod of the surveying and mapping instrument total station. The center position of the leveling seat 2 corresponds to the position directly below the prism base of the surveying and mapping instrument total station. By observing the position of the bubble in the universal level 7, adjust the adjusting nuts 4 around to make the leveling seat 2 level. At the same time, keep the upper end of the cross bracket 9 corresponding to the south direction. The intersection of the cross bracket 9 at the center position of the leveling seat 2 is identified as the reference point.

[0022] Step 2: Observe the total station eyepiece and adjust the telescopic length of the tripod in three directions so that the center of the prism base at the center of the tripod is aligned with the reference point area;

[0023] Step 3: Observe the level bubble in the liquid level on the rotating seat at the top of the total station, and adjust the top of the total station repeatedly by turning the adjustment knobs around it to level the top of the total station so that the center of the prism base is aligned with the reference point;

[0024] Step 4: Rotate the rotating seat at the upper end of the total station 180 degrees, observe the offset of the prism base bull's eye through the eyepiece and the scale bar 10 on the cross bracket 9, and mark the position of the prism base bull's eye at this time on the positioning plate 8, measure the offset direction and distance on the positioning plate 8 and record them. If it is offset by 3mm in the southeast direction relative to the reference point, open the eyepiece protective cover, adjust the screw knobs of the eyepiece up, down, left and right through the correction screws, so that the prism base bull's eye is aligned to the position where it is offset by 1.5mm in the southeast direction relative to the reference point (i.e., the half position), and repeat step 3 to align the prism base bull's eye with the reference point;

[0025] Step 5, repeat the operation in step 4, and repeat the operation until the upper rotating seat of the total station is rotated 180 degrees so that the center of the prism base is aligned with the reference point and stops.
