Description

Orthogonal formula scale foot prop

Technical field

The utility model relates to a kind of measurement servicing unit, especially a kind of structure is simple, convenient for the orthogonal formula mark of operation Ruler foot prop.

Background technique

In geodesic survey and engineering survey, need surveyors' staff (measurement of the level scale, total station reflecting prism centering Bar, satellite positioning surveys centering rod etc.) it stands upright on measurement index point and keeps vertical and in face of measuring devices such as levels, just may be used It measures, i.e. the plumbness of surveyors' staff and the deflection angle in face of level directly influences measurement accuracy.Previous The outer frame for measuring foot prop (tripod) is tabular, can not be applied to surveyors' staff, therefore needs the hand steered operation of survey crew, i.e., Survey crew is in surveyors' staff to hang down by observing whether the bubble of spirit level adjusts surveyors' staff between two parties, and by hand steered Straight state, it is not only time-consuming and laborious, but also it is difficult to ensure accurate leveling, to reduce the accuracy of measurement.On solving Problem is stated, the Chinese utility model patent of Patent No. 201220373858.9 discloses a kind of " sleeve clip type measurement tripod ", Main contributions are that the outer frame of traditional foot prop is changed to cyclic annular (sleeve clip type structure) by tabular (tripod head type structure), for the first time for Surveyors' staff provides dedicated measurement foot prop, improves the upright vertical accuracy of surveyors' staff.Patent No. 201310022381.9 Chinese utility model patent discloses a kind of " Holding-clamp type measurement foot rest ", further uses orthogonal point Solution adjustment principle improves " sleeve clip type measurement tripod ", accelerates regulating the speed for scale upright state.Concrete operations Journey is that first surveyors' staff is placed in pedestal, is fixedly connected with surveyors' staff with pedestal by fixed connection apparatus, and measurement is marked Ruler bottom is placed on measurement index point, generally facing level, then adjusts the outer subtended angle and length of stabilizer blade, sets up surveyors' staff energy It is enough stable and substantially vertical, then it so that surveyors' staff is in plumbness by finely tuning jackscrew.Patent No. 201610159164.8 Chinese utility model patent discloses a kind of the measurement foot prop of accurate regulation scale angle " can ", into One step solve horizontally rotating after scale straightening, aim at it is problem-oriented.However, above-mentioned measurement foot prop is also deposited in practical applications In following deficiency: (1) orthogonal foot prop used at present, stabilizer blade are located at the vertical and horizontal of rectangular scale, and when use can make to survey Amount person generates eccentric standing, leans to one side to operate, and is unfavorable for measuring work for a long time；(2) road level and scale fix and not with Foot prop is fixed, when adjusting scale upright state after scale rotation, it may appear that the bubble direction of L-type spirit level and foot prop (or branch Foot) adjust spiral direction it is inconsistent, affect the quick straightening of scale.

Summary of the invention

The utility model is that it is simple, just to provide a kind of structure in order to solve above-mentioned technical problem present in the prior art In the orthogonal formula scale foot prop of operation.

The technical solution of the utility model is: a kind of orthogonal formula scale foot prop has open annular pedestal, in split ring Rectangular aperture scale seat tool is connected with by vertical axis on the inside of shape pedestal, in open annular pedestal and rectangular aperture scale seat tool Between have spring, lateral jackscrew is equipped on open annular pedestal, the transverse direction jackscrew front end and rectangular aperture scale seat tool are right Side front end offsets, be evenly equipped on the open annular pedestal and the opposite face of opening with open annular pedestal rotation connect and Axis orthogonal two lateral screws in the horizontal plane, axis is equipped on lateral screw and transverse direction screw is coplanar and parallel Guide rail is socketed with the sliding block connecting with lateral screw thread on guide rail, there is slide-and-lock device on sliding block, and sliding block is equipped with axis Vertical connector, stabilizer blade connect with connector radial rotating, are equipped with and stretch on stabilizer blade in the horizontal plane for line and lateral screw Device is equipped with lateral pedal in stabilizer blade bottom, is further fixed on open annular pedestal parallel and orthogonal with lateral screw axis Two pipe spirit levels.

The utility model structure is simple, and the adjusting screw and stabilizer blade of foot prop are distributed in the opening opposite face of open annular pedestal Upper and orthogonal thereto formula distribution, not only ensure that the quick straightening of scale, but also effectively prevented surveyor's bias and stand, lean to one side to operate and ask Topic, convenient for operation；Simultaneously spirit level is directly fixed with foot prop, avoid L-type spirit level bubble direction and foot prop (or branch Foot) the inconsistent problem in the direction of spiral is adjusted, keep the operation of surveyor more easy, improves the work effect of the measurement of the level Rate.
