Abstract
The utility model discloses an indicating instrument for accurately centering instrument points in a whole station, and aims to provide the indicating instrument for centering the points, which is simple in structure and convenient to carry and can effectively improve the positioning accuracy of instruments in the whole station. The indicating instrument comprises a casing (1), and an observing opening (2), a light-incoming inlet (3) and a sample-placing opening (4) which are arranged on the casing (1), wherein the light-incoming inlet (3) is corresponding to the sample-placing opening (4) in position; a catoptric imaging group and a magnifying glass (6) which is matched with the observing opening (2) are also arranged on the casing (1); the catoptric imaging group is formed by a plurality of plane mirrors (5). By using the catoptric imaging group, a light point formed by an infrared ray which passes through the light-incoming inlet (3) at the sample-placing opening (4) can be observed by human eyes through the observing opening (2). The indicating instrument disclosed by the utility model can be applied to the field of architectural engineering.
Description
Technical field
The utility model relates to accurately centering indicator of a kind of total powerstation point position, relates in particular to a kind of total powerstation centering indicator that is applied to building field.
Background technology
Total powerstation is widely used in precise engineering survey or deformation monitoring fields such as heavy construction on the ground and construction of underground tunnel, is a kind of light harvesting, mechanical, electrically is the hi-tech surveying instrument of one, can realize the measurement to angle, distance, difference of height.Once settle instrument because of it and just can finish whole surveying works on this survey station, so be referred to as total powerstation.Before total powerstation uses, need position total powerstation; At first to a sampling point be set in the position of preparing to set up total powerstation, and set up total powerstation in the position near sampling point, open the infrared transmitter that is arranged on the total powerstation base then and make its emission infrared ray, adjust the luminous point that position base forms infrared ray on the ground at last and overlap with described sampling point.Yet in practical operation, the technician directly observes to judge whether the luminous point that infrared ray forms overlaps with sampling point by naked eyes, and this kind mode easily produces bigger error.In addition, in the process of regulating, the technician in order to ensure the intact needs of contraposition stand up adjustment, squat down see, stand up again adjustment, squat down and see these repetitive again, wherein have more operational inconvenience.
Summary of the invention
Technical problem to be solved in the utility model is to overcome the deficiencies in the prior art, provide a kind of simple in structure, be easy to carry, and can effectively solve the inaccurate accurate centering indicator in total powerstation point position that measuring accuracy is reduced of manual centering.
The technical scheme that the utility model adopts is: the utility model comprises housing and is arranged on observation port, the light inlet on the described housing and puts the sample mouth, described light inlet is corresponding with the described sample mouth position of putting, also be provided with the catoptric imaging group on the described housing and reach the magnifier suitable with described observation port, described catoptric imaging group is made up of some level crossings, by described catoptric imaging group, human eye can see that the infrared ray that passes described light inlet is at the described luminous point of putting the formation of sample mouth place from described observation port.
The geometric center place of described magnifier is provided with the center and indicates.
Also be provided with illuminating lamp on the described housing.
The beneficial effects of the utility model are: because the utility model comprises housing and is arranged on observation port on the described housing, light inlet and put the sample mouth, described light inlet is corresponding with the described sample mouth position of putting, also be provided with the catoptric imaging group on the described housing and reach the magnifier suitable with described observation port, described catoptric imaging group is made up of some level crossings, by described catoptric imaging group, human eye can see that the infrared ray that passes described light inlet is at the described luminous point of putting the formation of sample mouth place from observation port, so when operating personnel adjust, only need just can judge clearly by magnifier with downward surplus light the position relation of infrared ray luminous point and sampling point, improve the cheap property of operation greatly, reduced error simultaneously.
Further, the geometric center place of described magnifier is provided with the center and indicates, and this measure can further improve the degree of accuracy of centering.
Further owing to also be provided with illuminating lamp on the described housing, so the utility model also can be under the environment of dark operate as normal.

Embodiment:
Embodiment one:
As shown in Figure 1, the utility model comprises housing 1, and described housing 1 is provided with observation port 2, light inlet 3, puts sample mouth 4 and illuminating lamp 7, and described light inlet 3 is corresponding with described sample mouth 4 positions of putting, and all is rectangle; Also be set with on the described housing 1 the catoptric imaging group and with the suitable magnifier 6 of described observation port 2, the center of described magnifier 6 is provided with the center and indicates 8, described catoptric imaging group is made up of two level crossings 5 that are fixedly installed on described housing 1 inside, and described two level crossings 5 one-tenth angle in the horizontal direction can be determined according to the described particular location of sample mouth 4 on housing of putting; Before positioning for total powerstation, one sampling point 10 need be set on the ground, the infrared ray 9 that total powerstation sends passes described light inlet 3 and puts sample mouth 4 and shines on the ground, and form an infrared ray luminous point on the ground, described sampling point 10 reflects by two described level crossings 5 earlier with the position relation of described infrared ray luminous point, pass through the amplification of described magnifier 6 again, finally pass in operating personnel's the eye, this moment, operating personnel can observe the position relation of described sampling point 10 and described infrared ray luminous point on one side by described magnifier 6, just finely tune total powerstation on one side, described sampling point 10 is overlapped with described infrared ray luminous point.
Embodiment two:
As described in Figure 2, present embodiment and embodiment one are basic identical, and its difference is, the position of two described level crossings 5 of forming described catoptric imaging group is different, it finally still can reflex to described infrared ray 9 at described sampling point 10 places, reaches the purpose of centering; So the combination of two described level crossings 5 of any employing reaches the purpose that described infrared ray 9 is reflexed to described sampling point 10 places, all belongs to the equivalent technical solutions of present embodiment.
Embodiment three:
As shown in Figure 3, present embodiment and embodiment one are basic identical, its difference is that described catoptric imaging group is made up of three described level crossings 5 that are arranged in the described housing 1, and three described level crossings 5 can be determined according to the described particular location of putting sample mouth 4 with the angle that becomes of horizontal direction; So three or more the combination of described level crossing 5 of any employing reaches the purpose that described infrared ray 9 is reflexed to described sampling point 10 places, all belongs to the equivalent technical solutions of present embodiment.
The utility model can be applicable to building engineering field.
