Description

A kind of horizontal survey instrument

Technical field

The utility model relates to a kind of horizontal survey instrument.

Background technology

At present, horizontal survey instrument is commercially very common, such as Optical Split-Image Levelling Instrument, it can not only judge detection part whether level, and the data message that can deviate (as angle and scale), for the leveling work of reality brings great help, but, due to the restriction of own dimensions, the parts larger than Optical Split-Image Levelling Instrument size cannot be detected, and cause spendable value lower.

Summary of the invention

Technical problem to be solved in the utility model overcomes the deficiencies in the prior art, provides a kind of horizontal survey instrument of improvement, it is practical, structure is simple, enforcement is convenient.

For solving above technical matters, the utility model adopts following technical scheme:

A kind of horizontal survey instrument, it comprises horizon detector; For setting up horizon detector and self the part of load level detector can being adjusted to the bearing of horizontality; Fixedly be located at the crossbeam of bottom for being connected with UUT of bearing, the bottom level of its middle cross beam is arranged, and crossbeam can stretch out from both ends along its length direction and shrink setting, when crossbeam be in stretch out state time, the bottom surface of stretching out the extension at crossbeam two ends is positioned on same surface level.

Preferably, crossbeam has three joints at least.

Specifically implement and preferred aspect according to one of the present utility model, bearing comprise surface arrange place horizon detector region added, many with added phase threaded engagement and the catotropic bolt of bolt and be connected to the undercarriage be rotationally connected on crossbeam and with the bolt head of bolt, wherein multiple bolt distributes around added circumference.

Preferably, added have three angles, these three angles be wired to triangle, bolt has three and is distributed in leg-of-mutton drift angle and base angle place.

More preferably, triangle is isosceles triangle.

More preferably, undercarriage is identical with added shape.

In addition, horizon detector is Optical Split-Image Levelling Instrument.

Due to the enforcement of technique scheme, the utility model compared with prior art tool has the following advantages:

The utility model horizontal survey instrument, it is practical, and structure is simple, and it is convenient to implement, and cost is low.

Accompanying drawing explanation

Fig. 1 is the schematic front view of the utility model horizontal survey instrument;

Fig. 2 addedly in Fig. 1 overlooks enlarged diagram;

Wherein: 1, horizon detector (Optical Split-Image Levelling Instrument); 2, bearing; 20, added; 200, region (placement horizon detector); 21, bolt; 22, undercarriage; 3, crossbeam.

Embodiment

Below by specific embodiment, the utility model is further described.

As depicted in figs. 1 and 2, the present embodiment provides a kind of horizontal survey instrument, and it comprises horizon detector 1; For setting up horizon detector 1 and self the part of load level detector 1 can being adjusted to the bearing 2 of horizontality; Fixedly be located at the crossbeam 3 of bottom for being connected with UUT of bearing 2, the bottom level of its middle cross beam 3 is arranged, and crossbeam 3 can stretch out from both ends along its length direction and shrink setting, when crossbeam 3 be in stretch out state time, the bottom surface of stretching out the extension at crossbeam 3 two ends is positioned on same surface level.

In this example, crossbeam 3 has three joints.But concrete joint number can be selected according to the demand of reality, but must ensure that the joint number at two ends is the same, and ensure to be positioned at the bottom surface that outermost two saves extension and be positioned on same surface level.

In this example, bearing 2 comprise surface arrange place horizon detector region 200 added 20, many with added 20 phase threaded engagement and the catotropic bolt 21 of bolt and be connected to the undercarriage 22 be rotationally connected on crossbeam 3 and with the bolt head of bolt 21, wherein multiple bolt 21 around added 20 circumference distribute.

Concrete, added 20 have three angles, these three angles be wired to triangle, bolt 21 has three and is distributed in leg-of-mutton drift angle and base angle place.Further, this triangle is isosceles triangle.

In this example, undercarriage 22 is identical with the shape of added 21.Meanwhile, alleviating deadweight to maximize, adopting the shape shown in Fig. 2.

In addition, involved in this example horizon detector 1 is Optical Split-Image Levelling Instrument.Meanwhile, although adopt flexible mode to extend the length of crossbeam in this example, specifically can implementation not only this is a kind of.

Specific implementation process in this example is as follows:

When part dimension to be detected is less than or equal to the size of Optical Split-Image Levelling Instrument 1 bottom surface, Optical Split-Image Levelling Instrument 1 can be directly adopted to detect parts to be detected; When part dimension to be detected is greater than the size of Optical Split-Image Levelling Instrument 1 bottom surface, directly Optical Split-Image Levelling Instrument 1 is placed in region 200, then place (benchmark) in the horizontal plane, by swivel bolt 21, upper and lower frame 20,22 is be arranged in parallel, then extend crossbeam 3 according to actual needs, crossbeam 3 can be erected on parts to be detected, thus detect the levelness of UUT.

In sum, the utility model has the following advantages:

1, bearing can rapid adjustment to horizontality, horizontal survey instrument can be used fast;

2, crossbeam can stretch, and makes the practical of horizontal survey instrument;

3, use and carry very convenient, and cost is low.

Above the utility model is described in detail; its object is to allow the personage being familiar with this art can understand content of the present utility model and be implemented; protection domain of the present utility model can not be limited with this; all equivalences done according to Spirit Essence of the present utility model change or modify, and all should be encompassed in protection domain of the present utility model.
