Abstract
A differential angle-level gauge for correcting the horizontal state of object and measuring its inclination in building construction is composed of rule body with leveling tube and its support, gear set and pointer. The freely rotary rule body is supported by shell-type support, pedestal and rule leg, and can rotate by operating gear set to read out the precise inclination. Its advantages are high practicality and high precision.
Description
The present invention relates to a kind of level meter, the level meter at particularly a kind of energy measurement angle of inclination.
The level that level meter commonly used at present can be proofreaied and correct object tilts how much to spend and can't measure testee.A kind of " combined diagram level " arranged, and maximum can only be surveyed 5 ° with interior angle, also has the optical instrument of a kind of being called " spirit-leveling instrument ", though can take measurement of an angle, the layman generally can not use, but also is subjected to the restriction in place, and is inconvenient practical.992188636) and " the horizontal angulometer of center of gravity formula " (patent No.: 99218861X) patented technology: " liquid level angulation level meter " (patent No.:, though angle of inclination that can Measuring Object, (measuring accuracy generally can reach 0.5 ° but its measuring accuracy is not high, the highlyest also can only reach 0.25 °), otherwise will instrument do very big.
The objective of the invention is to overcome the deficiencies in the prior art, a kind of both energy measurements levelness is provided, the level gauge with differential angle measurement of energy measurement angle of inclination, and measuring accuracy again very high (measuring accuracy can reach 0.01 °, even 0.001 ° or higher).
The objective of the invention is to be achieved through the following technical solutions: a kind of level gauge with differential angle measurement, comprise: blade, chi pin, horizontal tube, it is characterized in that blade is fixed on the main shaft can rotate freely, horizontal tube is fixed on the blade that can rotate freely, main shaft is by the shell-type bracket supports, the shell-type support is by bearing support, bearing is seated on the chi pin, one end of main shaft and one group of gear set interlock, the final stage of gear set connects a pointer, support is fixed on the shell-type support, and the scale of angle measurement degree is arranged on the header board of support.The other end of main shaft is connected with another group gear set, and gear set quilt cover clamshell is lived, and the final stage axle head of gear set passes case and is connected with the handwheel of outside.
The present invention is simple in structure, and is easy to operate, can proofread and correct the level of object, the angle of inclination of energy measurement object again, and have the high characteristics of measuring accuracy (measuring accuracy can reach 0.01 °, even 0.001 ° or higher).
Describe the details of the present invention and the course of work in detail below in conjunction with Fig. 1, Fig. 2:
Fig. 1 is the A-A cut-open view of level gauge with differential angle measurement Fig. 2 of the present invention.
Fig. 2 is the B-B cut-open view of level gauge with differential angle measurement Fig. 1 of the present invention.
The present invention includes: blade 1, shell-type support 2, bearing 3, chi pin 4, main shaft 5, horizontal tube 6, ring-like transparent panel 7, gear set 8, header board 9, pointer 10, transparent panel 11, support plate 12, support 13, housing 14, fast gear set 15, case 16, handwheel 17, blade shroud 18, blade hub disk 19, fixed pointers 20 are formed.It is characterized in that blade 1 is fixed on the main shaft 5 can rotate freely, horizontal tube 6 is fixed on the blade 1 that can rotate freely, main shaft 5 is by 2 supportings of shell-type support, shell-type support 2 is by bearing 3 supportings, bearing 3 is seated on the chi pin 4, an end of main shaft 5 and 8 interlocks of one group of gear set, and the final stage of gear set 8 connects a pointer 10, support 13 is fixed on the shell-type support 2, and the scale of angle measurement degree is arranged on the header board 9 of support 13.The other end of main shaft 5 is connected with another group gear set 15, and gear set 15 is covered by case 16, and the final stage axle head of gear set 15 passes case 16 and is connected with the handwheel 17 of outside.
When mounted, at first level gauge with differential angle measurement should be seated on the levelling bench of standard, make 0 scale mark secured in alignment pointer 20 on the shroud 18, the indication of pointer 10 on the header board 9 that has scale also is 0, and at this moment the bubble of horizontal tube 6 should be on 0 line of middle place value.Be carved with the scale of angle measurement on the shroud 18 of blade 1, have a hole on the shroud of shell-type support 2, can observe the corresponding fixed pointers of scale 20 residing positions on the shroud 18 from hole, but reading accuracy is 1 ° a numerical value.When blade 1 rotates an angle, each grade gear by main shaft 5 driven gear groups 8 rotates, speed ratio according to gear set 8, be carved with the accurate numerical value of reading on the header board 9 that calibration is 100 equal portions scales less than 1 ° (as: speed ratio is, the exact value of reading can reach 0.1 °, 0.01 °, 0.001 ° respectively) at 1/36,1/360,1/3600 o'clock by pointer 10.Because the top of blade 1 is cut out one, the deviation of gravity center center that makes blade 1 is under horizontal tube 6, so no matter chi pin 4 is in the position at what inclination angle, blade 1 all can turn to the position of a balance automatically, and the reading that makes horizontal tube 6 is substantially on 0 line, if some deviations are arranged, can adjust by handwheel 17, the reading that makes horizontal tube is on 0 line of center, and this moment is by the reading of fixed pointers 20 and pointer 10 indications, the accurate angle of inclination that can record object.Some are not needed the civil engineering or the installation of accurate numerical value, and the read-only reading that gets fixed pointers 20 gets final product.
