Description

A kind of packaged type engineering measurement foot prop

Technical field

The utility model relates to engineering survey auxiliary tool, the engineering survey foot prop of specially a kind of packaged type.It is main It is used for the subsidiary of all kinds of measuring instruments, all kinds of measuring instruments to include that reversible rod, Sopwith staff, folding rule etc. are different types of Levelling rod and all kinds of significant bodies of rod, such as mark post, there are also with the matching used centering rod of electrical type instrument of surveying and mapping.

Background technique

At present in the design and construction stage of common engineering project, the focus of engineering survey mainly embodies a concentrated reflection of on the scene Ground exploration sets i.e. two links of construction lofting with engineering survey.Site survey process is mainly utilizing works measuring principle, by water Quasi- instrument, tacheometric pole and levelling rod, the tools such as theodolite and mark post complete the measurement of the basic parameters such as elevation, distance, angle, coordinate Work, and then the parameter informations such as related atural object, landforms are subjected to drawing drafting, drawing is finally applied to construction production and construction In link.

It is mainly that unit in charge of construction needs the atural object on drawing according to design requirement in construction field for construction lofting process Ground is corresponded, and workload is big, and the height of required precision is the basic characteristics and requirement of setting-out work.

Common engineering project setting-out link mainly utilizes electrical type instrument of surveying and mapping, such as total station at present, is constructing, is setting Count drawing provide position coordinate on the basis of, realize the point position of construction site it is accurate confirm with it is corresponding.Wherein, setting-out Process is the premise for guaranteeing construction process and smoothly carrying out, and the height of position precision directly affects engineering to a certain extent and applies Working medium amount, the more especially projects under construction such as the higher bridge of pair required precision, tunnel, the inaccurate of position probably can also Construction speed is influenced indirectly, or even also will affect construction cost.Setting-out process has important role in the pre- construction stage.One As project sites setting-out mode mainly utilizes is centering rod prism group or single prism group, cooperation electronics surveys and draws quasi-instrument Complete setting-out process.

In above-mentioned two working link, each mapping quasi-instrument, such as level, theodolite etc. can all have and mating makes with its Auxiliary tool, such as levelling rod, mark post, centering rod prism group.The corresponding auxiliary tool of these measuring instruments is in practical sight Special messenger has been required during surveying and has carried out collaboration erection, and reason is most of supplementary instrument all and can not independently set up or even nothing Method is independently upright.Cooperate with set up during, due to the influence of human factor, survey crew's handset in such as erection process Involuntary slight jitter and displacement during device, applying external force to tool leads to the sedimentation etc. of instrument, can all influence instrument The stability and accuracy of related data are read, virtually expands observation accidental error, influences testing precision.And in construction lofting In link, traditional setting-out process is mainly observed using centering rod prism group cooperation total station, but due to centering rod rib The mobility of microscope group is poor, can not carry out effective dynamic fit with total station well, and the leveling of the setting-out body of rod every time Stability and timeliness are weaker, it is not intended in reduce oxygen evolution rate, extend the time cycle of setting-out, to setting-out work efficiency There is negative effect.

Summary of the invention

The purpose of this utility model is effectively reduced during common engineering field exploring in the early stage of the project, levelling rod and mark The auxiliary measuring tool such as bar, which can not be fixed independently, changes random error of measurement brought by the factors such as face inconvenience with erection, levelling rod, it is intended to While reducing artificial labour, testing precision and efficiency is substantially improved.At the same time, in the reality of engineering project pre- construction stage In the ground surveying and locating course of work, since traditional centering rod prism group can not quickly carry out small position adjustment and movement, It is difficult to rapidly efficiently be cooperated with instruments such as total stations, and then caused oxygen evolution rate reduces, setting-out low efficiency is inferior to ask Topic.

A kind of packaged type engineering measurement foot prop, including length type variable expansion bracket leg, frame leg bottom end connect idler wheel, rolling Foot-operated brake pedal is arranged in wheel top, and foot prop upper end connects multi-function frame head；

The multi-function frame head is made of circular ring shape stand and the clamping screw rod being arranged on circular ring shape stand, circular ring shape frame Seat is equipped with threaded hole, and clamping screw rod, which is matched, to be set in threaded hole.

The utility model provides a stabilization and the engineering survey foot prop mobile convenient for fine tuning, is reducing manual labor While erection with the troublesome operations such as instrument are carried, greatly improve testing stability and precision, so preferably with measuring instrument Efficiently cooperated, saves testing time, improve the testing efficiency of engineering survey.,

The utility model can successfully complete under the premise of reducing error brought by manual operation and human factor More safe autonomous erection process, and then supplemental measurement tool more efficiently can be set up and use, testing efficiency is improved, is subtracted Shaoshi surveys all kinds of accidental errors caused by the human factor in operating process.

Such as, the utility model and centering rod prism group are combined, more efficiently dynamic project may be implemented and put Sample process avoids previous artificially argue for the sake of arguing manually and carries out the setting-out process of inefficient, the low precision of engineering setting out.For another example passing In the levelling rod use process of system, since levelling rod can not support oneself, survey crew is needed to set up manually, but is shaken by human body itself Influence, the reading of levelling rod is often difficult to stablize reading, influences on measurement result very big.

In conclusion the utility model design practices generalization with very strong, in particular for high-precision testing and put Sample requires, extreme environment testing acts on, and the special screnes such as tester number deficiency have great effect.
