Problems solved by technology

However, in actual operation, technicians judge whether the light spot formed by infrared rays coincides with the sample point by direct observation with the naked eye. This method is prone to large errors.
In addition, in the process of adjustment, in order to ensure that the alignment is intact, technicians need to stand up to adjust, squat down to look, stand up again to adjust, squat down to look at these repetitive actions, which cause more operational inconvenience

Embodiment 1

[0015] Such as figure 1 As shown, the present invention includes a housing 1, and the housing 1 is provided with an observation port 2, a light entrance 3, a sample setting port 4 and a lighting lamp 7, and the light entrance 3 and the position of the sample setting port 4 are Correspondingly, and all are rectangular; the housing 1 is also fixedly provided with a reflective imaging group and a magnifying glass 6 adapted to the observation port 2, and a center mark 8 is provided at the center of the magnifying glass 6, and the The reflection imaging group is composed of two plane mirrors 5 fixedly arranged inside the housing 1, and the angle of the two plane mirrors 5 in the horizontal direction can be determined according to the specific position of the sample setting port 4 on the housing ; Before positioning the total station, the same point 10 needs to be set on the ground, and the infrared rays 9 sent by the total station pass through the light entrance 3 and the sample se...

Embodiment 2

[0017] Such as figure 2 As mentioned above, this embodiment is basically the same as Embodiment 1, the difference is that the positions of the two flat mirrors 5 that make up the reflection imaging group are different, and it can still reflect the infrared rays 9 to the 10 places of the sample point, to achieve the purpose of centering; so any combination of two flat mirrors 5 to achieve the purpose of reflecting the infrared ray 9 to the 10 places of the sample point, all belong to the equivalent technical solution of the present embodiment .

Embodiment 3

[0019] Such as image 3 As shown, this embodiment is basically the same as Embodiment 1, the difference is that the reflective imaging group is composed of three plane mirrors 5 arranged in the housing 1, and the three plane mirrors 5 are connected to the horizontal The angle of direction can be determined according to the specific position of the sample setting port 4; so any combination of three or more than three flat mirrors 5 can be used to reflect the infrared ray 9 to the sample point 10. Purposes all belong to the equivalent technical solutions of this embodiment.

Abstract

The invention discloses a total station point location centering indicator, which provides the point location centering indicator with simple structure, easy carrying, and effectively enhanced total station positioning accuracy. The total station point location centering indicator comprises a casing (1), and an observation port (2), a light inlet (3) and a sample placing port (4) arranged on the casing (1), the position of the light inlet (3) and the position of the sample placing port (4) are corresponded, a reflection imaging group and a magnifier (6) adapted to the observation port (2) are arranged on the casing (1), the reflection imaging group is composed of several flat mirrors (5), through the reflection imaging group, and the light point of infrared ray formed at the sample placing port (4) through the light inlet (3) can be observed at the observation port (2) by people. The total station point location centering indicator can be used in the building engineering field.

Description

technical field [0001] The invention relates to a point position accurate centering indicator of a total station, in particular to a total station centering indicator applied in the construction field. Background technique [0002] The total station is widely used in the field of precision engineering measurement or deformation monitoring such as large-scale buildings on the ground and underground tunnel construction. Measurement. Because it can complete all the survey work on the station once the instrument is placed, it is called a total station. Before the total station is used, it is necessary to position the total station; first, set a sample point at the position where the total station is to be erected, and set up the total station at a position close to the sample point, and then turn on the The infrared transmitter of the base makes it emit infrared rays, and finally adjust the position of the base so that the light spots formed by the infrared rays on the ground ...
