Abstract
The utility model discloses a dotting device for vertical shaft connection survey. The dotting device comprises a fixing rack, and a reflecting prism which is movably arranged on the fixing rack, wherein left and right prism fixing and regulating shafts are symmetrically arranged at the left and right ends of the fixing rack respectively; upper and lower suspension holes are respectively formed at the upper end and the lower end of the fixing rack; upper and lower prism azimuth rotating components are respectively arranged inside the upper and lower suspension holes. The dotting device for vertical shaft connection survey has the advantages of simple structure, high dotting accuracy, relatively low cost and simple field fabrication; loss of the dotting accuracy caused by beam divergence of optical dotting and laser dotting is solved by using the suspended reflecting prism; the requirements of high-accuracy edge measurement and angle measurement of a total station can be met; the measurement can be begun as long as the dotting device is firmly suspended by a steel wire of which the diameter is smaller than 0.5mm on the construction site.
Description
Technical field
The utility model relates to the shaft connection survey field for engineerings such as subway, tunnel, mine, water conservancies, especially relates to a kind of shaft connection survey cultellation device.
Background technology
At present, at many engineering fields of shaft connection survey, many because the degree of depth of vertical shaft is large, flat edge length, construction technical staff has adopted the way of a lot of raising shaft connection survey cultellation precision, mostly produces little effect.
Summary of the invention
The utility model purpose is to provide a kind of cultellation precision shaft connection survey cultellation device high, simple in structure, that input cost is low.
For achieving the above object, the utility model can be taked following technical proposals:
Shaft connection survey described in the utility model cultellation device, it comprises fixed mount and is movably arranged on the reflecting prism on described fixed mount, is symmetrically arranged with respectively left and right prism secured adjusted axle at the left and right two ends of described fixed mount; Upper/lower terminal at its described fixed mount offers respectively upper and lower suppending hole, is respectively arranged with upper and lower prism rotary components in described upper and lower suppending hole.
Centerline deviation≤the 0.05mm of described upper and lower suppending hole, the rotating deviation≤0.05mm of described upper and lower prism rotary components.
Described upper and lower prism rotary components comprises respectively upper and lower turncap and is mated the upper and lower turning axle of use, offer respectively upper and lower fixation with steel wire hole on described upper and lower turning axle.
The utility model advantage is simple in structure, the cultellation precision is high, utilize suspension reflecting prism method to solve the cultellation loss of significance that optics cultellation, laser plumbing bring because of beam divergence, can meet the total powerstation high precision and survey the demand of limit, angle measurement, the cultellation precision of utilizing this device to access to be better than 0.3mm, calculate and the actual measurement demonstration utilizes this measurement device can improve the cultellation precision of 3 times than conventional steel wire paster method according to theory; It is relatively low that the fixed mount of this device adopts conventional almag to process cost, and scene performs simply, and the steel wire that only need be less than 0.5mm with diameter at the construction field (site) hangs and firmly can start to be measured.
