Description
Technical field
The present invention relates to a kind of measurement auxiliary device, especially a kind of processing ease, can effectively improve the clipping type of measuring efficient and validity and measure foot rest.
Background technique
When geodetic survey and engineering survey, surveyors' staff (measurement of the level scale, electronic tachometer reflecting prism centering rod, satellite positioning surveys centering rod etc.) need to be stood upright on survey mark point and go up and keep plumbness just can measure, the plumbness of surveyors' staff directly has influence on measuring accuracy.Because the pedestal of in the past measurement foot rest (tripod) is planar, can't be applied to surveyors' staff (measurement of the level scale, electronic tachometer reflecting prism centering rod, satellite positioning surveys centering rod etc.), therefore need the hand steered operation of survey crew, be whether survey crew adjusts surveyors' staff between two parties by the bubble of observing level indicator, and be in plumbness by the hand steered surveyors' staff that makes.Obviously, traditional method not only wastes time and energy, and is difficult to guarantee accurate leveling, thereby has reduced the validity of measuring.In order to address the above problem, number of patent application is 201210267959.2 Chinese invention patent, discloses a kind of " the cover clip is measured foot rest ".The main contributions of " cover clip measure foot rest " is that the pedestal with traditional foot rest changes to ring-type by planar, and be evenly equipped with at least three horizontal jackscrews on the ring-type pedestal, for surveyors' staff provides special-purpose measurement foot rest, improved the upright vertical validity of surveyors' staff first.Yet, also there is in actual applications following problem:
(1) because pedestal is closed ring-type, when surveyors' staff more slightly or when longer, the operation of inserting pedestal is effort comparatively just;
(2) surveyors' staff is adjust and fix by the top power realization of jackscrew is vertical, and the top power of jackscrew can only promote forward for surveyors' staff, but can't drop backward, has strengthened the difficulty to the adjustment of surveyors' staff perpendicularity; In addition, only have top power to be difficult to realize being fixedly connected with of pedestal and surveyors' staff, " non-integral " not only carries inconvenience, and each the measurement again after mobile all need to readjust, and wastes time and energy, and limited the raising of measuring efficient;
(3) in the time can't guaranteeing that pedestal is in level due to reasons such as landform, just be difficult to realize the vertical adjustment to surveyors' staff, cause surveyors' staff to work.
Summary of the invention
The present invention is in order to solve the existing above-mentioned technical problem of prior art, a kind of processing ease to be provided, can effectively to improve the clipping type measurement foot rest of measuring efficient and validity.
Technical solution of the present invention is: a kind of clipping type is measured foot rest, the leg that pedestal is arranged and join with pedestal, pedestal is ring-type, on described pedestal, opening is arranged, be furnished with two horizontal jackscrews on pedestal, the front end of each horizontal jackscrew all has fixed connection apparatus, perhaps is furnished with three horizontal jackscrews on pedestal, and horizontal jackscrew front end placed in the middle has fixed connection apparatus; Mutually vertical between described adjacent transverse jackscrew axis.
Described horizontal jackscrew middle part is connected to the stiffness spring coaxial with horizontal jackscrew.
Described horizontal jackscrew joins by nut and pedestal, and horizontal bar-shaped trough is arranged on pedestal, and described nut can slide along horizontal bar-shaped trough.
Described pedestal lower end joins by three foot screws and the shape sub-mount similar with pedestal, and lower end and the leg of described sub-mount join.
Described fixed connection apparatus is spring clip, magnet or G type folder, and described G type folder is provided with fastening screw.
The present invention compared with prior art has following advantage:
(1) owing on the ring-type pedestal, opening being arranged,, can easily surveyors' staff be inserted in pedestal by opening more slightly or when longer when surveyors' staff, it is time saving and energy saving to operate;
(2) surveyors' staff is to realize vertical adjustment and fixing by the top power of jackscrew and the acting in conjunction of fixed connecting piece, can realize the promotion forward of surveyors' staff and drop backward, the torsion that also can avoid simultaneously jackscrew to be in course of adjustment and to produce is convenient to quick perpendicularity adjustment to surveyors' staff; Can guarantee that surveyors' staff is in plumbness all the time, has guaranteed measuring accuracy; Can realize simultaneously being fixedly connected with of pedestal and surveyors' staff, not only easy to carry, and also each movement need not to remake accurate adjustment, improved measurement efficient;
(3) in the time can't guaranteeing that pedestal is in level due to reasons such as landform, just can guarantee that pedestal is in level by adjusting foot screw, thereby realize the vertical adjustment to surveyors' staff, make surveying work not limited by the place.
