Abstract
The utility model relates to a direct reading measuring instrument for the curved path which is c measuring instrument used for measurments of the building and the civil engineering. The whole appearance of the direct reading measuring instrument for the curved path is in flat shaped half circular arc shape, and angle scales or length scales are marked on both sides and the surface of the circular arc. Besides, the utility model can adjust and measure sizes of bubbles in the curved path. The direct reading measuring instrument for the curved path has quite wide range of use. The direct reading measuring instrument for the curved path can also be used for measuring the outer rail height of the railroad curve besides measuring included angles between a space object and the horizontal line and the plumb line. The user can directly read the angle or the dimension according to requirement. The utility model brings very large convenience for the construction measurement.
Description
The curved path measuring instrument is used for building, the measuring a kind of measurer of civil engineering work.
The frequent use angle chis of department such as present building, civil engineering work, measurers such as surveyor's staff, vertical, frame-type level meter, though above measurer is easy to use, usable range has very big limitation.Can only measure angle between two straight lines as bevel protractor, can not the measurement space object and pedal line, horizontal line between angle; Surveyor's staff, vertical, frame-type inclinometer can only be used for measurement level or vertical missing, and can't read misalignment angle, thereby can not directly read numerical value in construction survey, cause construction survey inconvenience.
Task of the present utility model is exactly for solving the existing shortcoming of above measurer, designing a kind of novel curved path measuring instrument.Curved path measuring instrument usable range is wider, can be used for the angle between measurement space object and level, the pedal line, also can be used for the measurement of the outer rail height in the railway curve, and can directly read angle or yardstick as required.
Fig. 1 is the stereo appearance figure of curved path measuring instrument;
Fig. 2 is the configuration state figure of curved path measuring instrument;
Fig. 3 indicates the stereo appearance figure of yardstick scale for the curved path measuring instrument.
Utilize the example in the accompanying drawing below, introduce the effect and the architectural feature of curved path measuring instrument in detail.
The whole profile of curved path measuring instrument is flat semicircle arcuation, as shown in figures 1 and 3.It mainly is made up of housing 1, adjustment core 2, base plate 3, adjustment bolt 4 and liquid 5, forms and measures Qu Lu chamber 6 and liquid air chamber 7.Housing 1 is half circular-arc flat semicircle arcuation cavity that surrounds, and by adjusting core 2 cavity is split up into measurement Qu Lu chamber 6 and liquid air chamber 7 in the thin-walled that cavity wall is made for the homogeneous transparent material, cavity, injects ideal liquid in the cavity.Measure the bubble that leaves an an amount of size when injecting liquid in the Qu Lu chamber 6, under the effect of gravity, liquid gathers in the cavity bottom, and bubble floats on top, as shown in Figure 2.Adjust core 2 middle parts and be provided with cross over pipe, the top of cross over pipe communicates bottom UNICOM liquid air chamber 7 with measurement Qu Lu chamber 6.Adjust bolt 4 and connect as one by the cross over pipe of adjusting core 2 middle parts, be divided into two not connected air chambers measuring Qu Lu chamber 6 and liquid air chamber 7 in the bottom center of curved path measuring instrument base plate 3.
Housing 1 both sides and the arc surface of curved path measuring instrument are marked with the angle index chi, and it can suitably increase the R value of circular arc according to the actual needs of measurement range and precision, and the interval with each degree is divided into some equal portions again, makes the measurement scale.Measure in the real work at some, what need is long measure, and long measure is the functional value of certain angle, therefore angle can be scaled long measure to be marked on the housing 1, as shown in Figure 3, so that directly read length numerical value.
Measure Qu Lu chamber 6 its sections and be advisable, measure the volume of Qu Lu chamber 6 and the volume of every side liquid air chamber 7 and account for 1/3rd of curved path measuring instrument cavity with 5 * 6 millimeters.The bubble of measuring in the Qu Lu chamber 6 can be adjusted, as long as will adjust bolt 4 cross over pipe of back-outing, but measures just UNICOM of Qu Lu chamber 6 and liquid air chamber 7, reaches the purpose of adjustment bubble.The liquid injection rate IR accounts for 2/3rds of whole curved path instrument cavity.Can guarantee the operate as normal of curved path measuring instrument like this.
The curved path measuring instrument is easy to use, of many uses, and measurement range is big, can satisfy the general measure needs of aspects such as civil construction project, in construction survey, can directly read numerical value, brings great convenience to construction survey.
