Technical field

The present invention relates to engineering measuring technology fields, and in particular to a kind of Surveying Engineering A-frame.

Background technique

Currently, in engineering construction planning and designing, construction and management stage measure it is various required by work Orientation, angle measurement, surveys high, mapping and photogrammetric etc. instrument at ranging.In measurement process, need using mapping three Foot prop is used to support measuring instrument, such as theodolite etc., therefore a level, stable A-frame are very heavy for mapping Generally it is impossible to meet the demands that fine measuring instrument is used in complicated landform for the mapping tripod wanted, but now used；It surveyed and drew Journey is complicated for operation, in actual use, move repeatedly adjustment with the multi-group data of measuring target point, A-frame is not Flat, the unstable mapping positioning measurement working efficiency that easily leads to is low, can not achieve quick mapping；And do not have in existing mapping position indicator There is consideration to find mapping positioning device carry out level itself accurately, calculates complicated, influence so as to cause mapping operations and mapped results Measurement accuracy.The invention proposes a kind of Surveying Engineering A-frames thus.

Summary of the invention

In view of the above problems, it the invention proposes a kind of Surveying Engineering A-frame, can effectively adapt to multiple The mapping of miscellaneous landform can reduce the work difficulty of staff, tripod is avoided to glance off, and improve mapping precision, device Simple with structure, operation is easy, the characteristics of being easy to carry about with one and carry.

In order to achieve the above purpose, the following technical solution is employed by the present invention:

A kind of Surveying Engineering A-frame, including support device, regulating device, the support device include pedestal, supporting leg, consolidate Determine anchor, the base bottom is hingedly equipped with the supporting leg, and the supporting leg end is equipped with the fixed anchor, the regulating device Including straight-bar, lantern ring one, lantern ring two, limited block, vertical, plate face, the straight-bar is fixedly arranged on the base bottom, on the straight-bar Set is equipped with the lantern ring one, and two sets of the lantern ring is arranged on the supporting leg, passes through connection between the lantern ring one, lantern ring two Bar connection, the connecting rod both ends are respectively articulated on the lantern ring one, lantern ring two, and the straight-bar end is equipped with the limit Block, the limited block bottom centre and right side are respectively equipped with fixed link and the vertical, and the fixed link end is equipped with the plate Face.

Preferably, the lantern ring one is equipped with fixing bolt one.

Preferably, the lantern ring two is equipped with fixing bolt two.

Preferably, the fixed link right side central is equipped with spirit level.

Preferably, middle side part is equipped with graduation mark in the plate face.

Due to using above-mentioned technical solution, the beneficial effects of the present invention are: the present invention adjusts each by connecting rod The angle of support leg guarantees that pedestal is in a horizontal position by the way that vertical and spirit level are dual, energy to adapt to the mapping in complicated landform The work difficulty for enough reducing staff, avoids tripod and glances off, and improves mapping precision, and apparatus structure is simple, behaviour Make easy, is easy to carry about with one and carries, effectively enhance the practicability of invention.
