Description

Fixed tripod adjustment and calibration measuring base device

Technical Field

The utility model relates to an engineering measuring instrument equipment examines school technical field, specifically is a base device is measured to fixed tripod timing.

Background

In engineering projects, GPS measurement and total station wire measurement are widely applied to control network retest and encryption, and a measurement base is frequently used in the measurements; during the transportation, transportation and use of measuring equipment, a measuring base is often deviated from the center in a leveling and centering state, so that the center of an instrument is not coincident with the center of a control point or is not within an allowable error range, before the operation of a measuring task, the measuring base needs to be calibrated, the offset of the base is corrected only by the estimation of experience of a measuring person in the calibration process, the operation can be finished only in places with flat terrain such as outdoor hardened ground and the like, the calibration work cannot be finished indoors, a tripod is opened and horizontally placed on the ground and is not fixed, the centering position can be changed due to the movement of the tripod in the operation process of the instrument, a centering device has no obvious mark, the offset can be mastered only by estimation in the line drawing operation, when the measuring task is heavy, the number of bases needing to be calibrated is large, and the calibration work can be finished only by repeatedly adjusting one base for 3-5 times, the occupied preparation time and the personnel investment are large.

Disclosure of Invention

Aiming at the defects of the prior art, the utility model provides a fixed tripod timing measuring base device, which can accurately and quickly timing the measuring base, reduce the preparation time of the measuring operation, ensure the accuracy and reliability of the measuring result and finish the timing work indoors; the method has the advantages that the method can quickly start a measurer who enters a workplace, master the adjustment principle, quickly find whether a measuring base has problems or not in the measuring task process, guarantee measuring accuracy, and solve the problems of long preparation time occupied by the conventional adjustment mode and large personnel investment.

In order to achieve the above object, the utility model provides a following technical scheme: the utility model provides a fixed tripod timing measurement base device, is including leveling the disc base of placing, on three legs of tripod extension highly unanimous are fixed in the disc base, and on three legs of tripod were fixed in the disc base through fixed foot rest bottom cushion cap, fixed foot rest bottom cushion cap spin was equipped with the bolt of screwing in order to lock three legs of tripod, and the middle part of disc base upper end is fixed with the centralizer of taking the scale.

In the adjusting and measuring base device, the foot rest jacking platform at the upper end of the tripod is positioned right above the centralizer.

In the calibration and measurement base device, the middle part of the centralizer is provided with a cross line with scales.

In the adjusting and measuring base device, the bottom bearing platforms of the three fixed foot rests are distributed and fixed on the upper end surface of the disc base in an equilateral triangle, and the distances from the bottom bearing platforms of the three fixed foot rests to the center of the disc base are the same.

Compared with the prior art, the utility model utilizes the disc base and the fixed tripod to calibrate the measuring base device, and can complete the calibration work indoors, thereby reducing the calibration time, reducing the personnel investment and improving the working efficiency; through the adjusted base, when measurement operation is carried out, the precision of measurement results is ensured, and the service level of measurement personnel is improved; the device is easy to carry, simple to operate and easy to realize.

FIG. 1 is a schematic structural view of the present invention;

fig. 2 is a schematic structural view of the centralizer.

Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Referring to fig. 1-2, a fixed tripod adjusting and measuring base device comprises a disc base 1 which is flatly placed, three fixed tripod bottom bearing platforms 2 are distributed and fixed on the upper end surface of the disc base 1 in an equilateral triangle mode, the distances from the three fixed tripod bottom bearing platforms 2 to the center of the disc base 1 are the same, a tripod 5 is erected on the disc base 1, three legs of the tripod 5 are fixed on the disc base 1 through the three fixed tripod bottom bearing platforms 2, a screwing bolt 3 is arranged on the fixed tripod bottom bearing platforms 2 in a screwing mode to lock the three legs of the tripod 5, a centering device 4 with scales is fixed in the middle of the upper end of the disc base 1, a tripod jacking platform at the upper end of the tripod 5 is located right above the centering device 4, and a cross line with scales is arranged in the middle of the centering device 4.

The floor tiles are smooth indoors, the triangular support 5 is difficult to stably erect, and the adjustment work is difficult to finish indoors. The disc base 1 is placed on the ground to prevent slipping, 3 fixed foot rest bottom cushion caps 2 are arranged at equal intervals to the circle center (the base center is located near the center of a centering device 4 with scales when the tripod 5 is fixed), the tripod 5 is screwed and fixed, the base 6 is measured by leveling, whether the center of the measuring base 6 is located at the center of the centering device 4 is checked when the base is rotated by 180 degrees, if the centering exceeds the scale mark by more than 1mm, half of the offset of the measuring base 6 is adjusted, the centering and leveling are carried out again, and the adjustment and calibration of the measuring base 6 can be completed by repeating for 1-2 times.

It is noted that, herein, relational terms such as first and second, and the like may be used solely to distinguish one entity or action from another entity or action without necessarily requiring or implying any actual such relationship or order between such entities or actions.
