Abstract
The utility model relates to a tube inner measurement ruler. Edge metal frames of an edge ruler of a wooden ruler are made of L-shaped aluminium alloy angle beads. Through connecting the L-shaped aluminium alloy angle beads with the wooden ruler, two grooves of the L-shaped aluminium alloy angle beads are provided with LED lighting tubes. A battery is fixed in the metal frame and is used to provide power for the LED lighting tubes. A top end of the tube inner measurement ruler is connected with an end of a suspended steel wire, and the other end is connected with a magnet. The tube inner measurement ruler is advantaged in that when the tube inner measurement ruler is used, the magnet is absorbed on a centerline of a steel tube top, and the ruler is connected with the ruler top through the steel wire, so the tube inner measurement ruler is vertically suspended and is in a vertical state. The LED lighting tubes illuminate scale on a scale surface of the measurement ruler. Outside of a tube hole, elevation of any point of a tube can be rapidly measured by a common measuring method by a precision level, and sedimentation deformation amount of a certain point of the tube is obtained by comparing difference of elevation obtained by the measurement. Through improvement of the structure of the measurement ruler, the measurement ruler is provided with the scale, and can give out light, so that inner tube measurement is easy, intuitive and accurate, and work efficiency is improved.
Description
Technical field
The utility model relates to pipe curtain survey instrument, particularly surveys chi in a kind of pipe.
Background technology
In recent years, along with the exploitation of civil engineering work new technology, pipe curtain engineering method is used in crossings on different level more and more and is passed through in engineering.Pass through as Interchanges in Cities, cross the ferry bus tunnel under airfield runway, pass through Conveyance Box Culvert etc. under highway.
Pipe curtain under squeezing into road or roadbed after, requirement of engineering is measured absolute altitude and the sinking displacement amount of pipe top each point on the pipe longitudinal profile at any time.Press the traditional measurement thinking, the frame precision level is arranged on the outer extended line of pore, and collimation axis is aimed at survey chi scale reading in pore, just can calculate the absolute altitude that pipe pushes up certain point.But the light in pipe is usually very dim, and spirit-leveling instrument can not be observed and survey the chi scale reading, and new through looking into, common survey is also had no idea to enter and gone direct measurement in pipe at present.
How to address this problem and just become the problem that those skilled in the art will study and solve.
Summary of the invention
The purpose of this utility model is exactly the deficiency that exists for prior art, by to surveying the chi architecture advances, designs a kind of have scale, the luminous survey chi of energy, makes and measures processing ease in pipe, and is directly perceived accurate, increases work efficiency.Just solved and directly measured a difficult problem in pipe.
The utility model is to realize by such technical scheme: survey chi in a kind of pipe, comprise wooden rule, the edge of the edge rule of wooden rule comprises metal edge frame, metal edge frame is made by L-type aluminium alloy corner protector, L-type aluminium alloy corner protector is connected with wooden rule by wood screw, the LED luminous lamp tube is installed in two grooves of L-type aluminium alloy corner protector, and battery is fixed in metal edge frame, is used to the LED luminous lamp tube that power supply is provided;
The top of surveying chi in pipe connects an end of the steel wire of suspention, and the steel wire other end connects magnet.
the beneficial effects of the utility model are: survey chi in pipe when using, magnet is inhaled on pipe curtain steel pipe top center line, connecting chi by steel wire pushes up, survey vertical suspention of chi in pipe, be the vertical state, the LED luminous lamp tube illuminates the reading of surveying on chi scale face, pore external application precision level can record rapidly the elevation of pipe arbitrfary point by the common survey method, the difference of elevation that relatively, twice records has namely obtained the deformation of sedimentation of pipe point, by to surveying the chi architecture advances, survey chi scale is arranged, can be luminous, make and measure processing ease in pipe, accurately directly perceived, improved work efficiency, solved and directly measured a difficult problem in pipe.
