Abstract

The utility model relates to an instrument used for measuring a space angle, which is mainly composed a dial plate, an indicating needle and an eccentric driver, wherein the indicating needle is always perpendicular to the ground level horizontal line, the eccentric driver and the indicating needle are fixed on the same rotating shaft, and an external casing, a base and the dial plate are fixed together. The utility model can be widely applied to the installation of equipment, pipelines, bridges and steel constructions, the setting and the checking of the levelness, the verticality, the angle and the gradient in civil engineering construction, and the checking of the levelness and the gradient of the highway and the railroad. The utility model can also be arranged on a ship to measure and work out the height of billows.

Description

Space angular gauge

The utility model is a kind of instrument, and being used for measuring with coordinate Z axle is the space angle instrument of any space angle of benchmark.

Generally adopt level measurement levelness and verticality at present, its measurement range is very little, arbitrarily angled in 360 ° of scopes of energy measurement more not, therefore, in the real work, when levelness and verticality require under the undemanding situation, just by rule of thumb or extremely inaccurate range estimation determine, the ground of building trade often adopts pouring water test to check its level and gradient situation, though whether this has the gradient to be difficult to measure the size of its value as can be known, the more important thing is and can't construct by the gradient of design, although also use transit survey sometimes, but when if the place is narrow and small, then transit is also powerless.Therefore, because the deficiencies in the prior art usually can cause the inferior of construction quality.

The purpose of this utility model provides a kind of place environmental baseline that can not be subjected to easily and limits, can measure the space angle instrument of unspecified angle, it can not only measure any object in the space residing angle, but also can adjust according to its indicated value, make object reach the angle of expection.

The purpose of this utility model is achieved in that pointer and eccentric driver are fixed on the same turning axle, can produce relative displacement with structure unitary housing body, base and dial plate, pointer since the effect of eccentric driver all the time perpendicular to horizon, the angle of base on measured object be the rotational angle of dial plate just, pointer is promptly indicated corresponding scale value, reach the purpose of measurement, this is to form according to ground mental and physical efforts and how much equal principle design of corresponding angle.

Because adopt such scheme, can measure accurately with coordinate Z axle is arbitrary space angle of benchmark, the utility model is measured accurately, structure is very simple, volume is little, carry and easy to use, and cost is low.Realized purpose of the present invention, and can widespread use in every construction activities of the mankind it, for example: equipment is installed, levelness, the verticality of engineerings such as Steel Structure Installation, pipeline laying, civil engineering, bridge construction, the setting of angle or gradient and detection; The levelness of highway, railway and the setting of the gradient and detection; Verticality when that is afraid of to place foot bolt and erects wire pole all needs its help; Even this space angle instrument placed on the train, when train running, can measure the level and the gradient of track, place on the automobile, can measure the level and the gradient of highway pavement, when the indicated value with mileage and space angle instrument is a function, can draw out the highway topomap, place and can measure lifting or underriding angle on the aircraft, place and to measure great waves height (converting) on the steamer, also can be used to measure the emission angle of weapon with triangle formula.

Below in conjunction with drawings and Examples the utility model is further specified.

Among the figure: 1. 5. on housing 2. visors 3. pointers 4. screws support 6. 7. spacer sleeve 8. dial plates 9. distance collars 10. permanent magnets 11. bases 12. bonnets 13. eccentric drivers 14. screws

［ 5 ］ (2) are by spacer sleeve ［ 7 ］ spacing for the supporting of figure axis, and dial plate ［ 8 ］ is fixed on the bonnet ［ 12 ］ through screw ［ 4 ］ (2).Pointer ［ 3 ］ and eccentric driver ［ 13 ］ are fixed on the axle ［ 6 ］, and support ［ 5 ］ at axle and upward freely rotate, visor ［ 2 ］ and distance collar ［ 9 ］ are clamp-oned in the housing ［ 1 ］ by bonnet ［ 12 ］, housing ［ 1 ］ and bonnet ［ 12 ］ are through the cementing agent combination, permanent magnet ［ 10 ］ embeds on the base ［ 11 ］, and is fastened in the housing ［ 1 ］ by screw ［ 14 ］ (2).The effect of permanent magnet is can be adsorbed on the tested carbon steel metal, and effect is best like this, can be while surveying hue angle, any angle of base ［ 11 ］ will reach the purpose of surveying the inspection space angle like this by the corresponding indication of pointer ［ 3 ］.

Claims (3)
