Description
Technical field
The utility model belongs to the connection survey technical field in the control survey in the fields such as subway, underground power house, hydraulic engineering, is particularly a kind ofly applied in vertical space the connection survey portable activity support transmitting plane and elevation.
Background technology
Along with rapid development of economy, the control survey wire in underground engineering construction imports the metering system widespread use of underground into by ground.In Urban Metro Construction engineering, Controling network will from importing underground on the ground, and whole transmittance process needs to complete one-shaft orientation connection triangle by support suspension wire and measures (or two wells are directed).Because vertical shaft surrounding environment is complicated, large-scale conventional stent can not be used to carry out connection survey, also have a kind of support be welded and fixed around vertical shaft exactly to carry out connection survey.But this fixed support is dumb, can not adjust according to the change of the actual conditions at scene, although what can not meet in site operation process very stable is flexible and changeable, therefore causes Measurement sensibility and poor reliability.
Summary of the invention
The utility model provides a kind of stability and good reliability, the connection survey portable activity support of the camp site that the condition that can conform is changeable for solving in known technology the technical matters that exists.
The technical scheme that the utility model is taked for the technical matters existed in solution known technology is:
A kind of connection survey portable activity support, comprise the first ground supports and the second ground supports, described first ground supports is connected with drum, described first ground supports upper end and link span are rotationally connected, described second ground supports upper end is fixedly connected with link span is vertical, described link span is also rotationally connected with the one end of choosing support, the described other end choosing support is provided with the sheave shaft of band pulley, described middle part of choosing support is rotationally connected with regulating one end of strut bar, the other end of described adjustment strut bar arranges multiple mentioning, described mentioning coordinates with the adjust bar be arranged in the second ground supports.
Described link span is provided with the first axle and the second axle, described first axle sleeve is connected to the first sleeve pipe that the first ground supports top connects, described second ground supports top steel pipe fixedly welds with vertical in the middle part of link span, described 3rd axle sleeve be connected to choose support end sleeve pipe in.
Described first ground supports and the second ground supports are the framed structure be made up of steel pipe, and described second ground supports frame rack is connected with multiple adjust bar, and described first ground supports frame rack has multiple fixed connecting rod.
First sleeve pipe on described first ground supports top is connected with limited impression.
Described drum is provided with the spacing hole of crank and fixing drum.
The advantage that the utility model has and good effect are: the utility model structure is simple, first ground supports and the second ground supports form ground supports system, increase counterweight in the first ground supports and the second ground supports and hang steel wire needs to meet, choose support and regulate height by regulating strut bar, steel wire arrives the limited impression at the first ground supports top by drum, then the pulley choosing support is arrived, vertically enter into vertical shaft, circumstance complication in connection survey process can be met to the flexible and changeable demand of support, improve stability and the reliability of connection survey.
