Abstract
The invention relates to a vest-pocket altimeter range finder, which mainly comprises a base, a sector gear, a driven gear, an amplifying telescope, a pointer, a dial scale and a braking strip, wherein the amplifying telescope is arranged at the topmost end of base; the sector gear is arranged at one end of the base and below the amplifying telescope; the driven gear is engaged with the sector gear; the driven gear is homocentric with the dial scale; a wheel shaft of the driven gear is provided with the pointer; and the braking strip is arranged below the driven gear and is controlled by a braking button. The vest-pocket altimeter range finder has the characteristics of small volume, light weight, convenient carrying, low cost, easy operation, precise measurement, time saving, labor saving and high operating efficiency; and the measuring angle is amplified by 6 times maximally, so the measuring precision is improved greatly. The altimeter range finder is suitable for the measurement work in cities and towns, plains, hills, plateaus, forests, mountain areas and water surfaces, and can work in an environment of intense magnetic field and highfield. The vest-pocket altimeter range finder can measure high-position objects from low positions and low-position objects from high positions due to the capability of measuring elevation angles and depression angles.
Description
Technical field
The present invention relates to a kind of measuring height and distance instrument that the elevation angle that measures or the angle of depression are amplified, can be used for measuring height and distance by departments such as electric power, telecommunications, military affairs, urban construction, land and water transportation, forest reserves generaI investigations.
Background technology
Along with high speed development of national economy, a kind of cheap, in light weight, easy to carry, measuring height and distance instrument that measuring accuracy is high is badly in need of in a lot of departments.Measuring height and distance instrument commonly used at present is meant that the pin institute how and the scope of actual measurement pitch angle are 1: 1; Therefore make measuring accuracy not high, well-known, survey is high, the most frequently used angle of range finding is below 90 °; 60 ° with lower angle use at most, the pitch angle that surpasses 90 ° does not need forever; Have plenty of under given conditions and measure, the price that has is higher or carry inconvenience, brings certain difficulty to the user.In sum, measuring accuracy is increased substantially, existing measuring equipment still can not finely solve.
Summary of the invention
The technical matters that the present invention will solve is: it is high, easy to carry, cheap to design a kind of measuring accuracy; Have on measured object ground under the situation of obstacle; Also can measure the height of measured object or the vest-pocket altimeter range finder device of horizontal range, can increase work efficiency greatly and work quality.
The technical scheme that solution problem of the present invention is taked is: this instrument mainly is made up of base, sector gear, follower gear, amplification telescope, pointer, index dial, braking bar; Amplify telescope and be arranged on base topmost; The center of circle of sector gear is fixed on and is located on the base that amplifies the telescope below; When rotating this instrument, sector gear leans on the weight of self under the terrestrial gravitation effect, to freely swing around its axle center; Follower gear be located at below the sector gear and with the sector gear engagement, sector gear adopts 120 degree angles, its follower gear that rotates 60 degree and its engagement rotates a week, sector gear or adopt 180 degree angles, it rotates 90 degree, rotates a week with the follower gear of its engagement; Follower gear and index dial concentric, pointer are installed on the wheel shaft of follower gear; The braking bar is located at the follower gear below perpendicular to the circumference of follower gear, by a locking key control.
Be provided with balancing weight in the sector gear middle and lower part.
On the braking bar, a locating slot is arranged, leading portion is with a compression spring; One braking clamp is arranged on the locking key, and braking clamp is stuck in the locating slot, and the front has a brake check spring to withstand locking key.
Be provided with a braking cushion rubber bumper in braking bar front end.
A small-sized function calculator is installed on the base of this instrument other end.
The impact shock that brings when reducing to brake, the profile of tooth of transmission gear adopts the herringbone tooth.
Good effect of the present invention is: little, in light weight, easy to carry, cheap, the easy operation of instrument volume; Less demanding to measurement data, do not need falsework to get final product work; If the band A-frame, measuring accuracy is higher; Time saving and energy saving, high efficiency; Can make takes measurement of an angle amplifies 4-6 doubly, so measuring accuracy improves greatly; This instrument is applicable to cities and towns, Plain, hills, plateau, forest, mountain area and surface measurement work; Be applicable to high and cold, high temperature is regional; Can under high-intensity magnetic field, highfield environment, work; Because of recording the elevation angle, the angle of depression, so can survey eminence, all can from lower from eminence survey lower object.
Description of drawings
Accompanying drawing 1 is to be synoptic diagram of the present invention; Accompanying drawing 2 is that A-A is to cut-open view.
Embodiment
Like accompanying drawing 1, shown in 2; This instrument mainly is made up of base 2, sector gear 10, follower gear 11, amplification telescope 1, pointer 5, index dial 4, braking bar 8; Amplify telescope 1 and be arranged on base 2 topmost, the axle center of sector gear 10 is fixed on the base 2 that amplifies telescope 1 below, is inlaid with mercury balancing weight 9 at 10 times middle parts of sector gear; When rotating this instrument, sector gear 10 leans on the weight of self under the terrestrial gravitation effect, to freely swing around its axle center; The fan shape angle degree of sector gear 10 is 120 °, drives a follower gear 11, and when sector gear 10 rotated 60 °, follower gear 11 just in time rotated for 1 week; Produce error for preventing gear drive and pressing to impact when locking key 14 braking bars 8 are braked, the profile of tooth of transmission gear adopts the herringbone tooth.Follower gear 11 and index dial 4 concentrics are coated with a cloche 7 on the index dial 4; Pointer 5 is installed on the wheel shaft of follower gear 11, and when pointer 5 rotated a week, the angle that sign is measured was 60 °; In 360 ° scope, mark 60 ° scale, so; Pointer institute how is 6: 1 with actual measurement pitch angle scope, so its precision just improves 6 times.Braking bar 8 is located in the gathering sill on follower gear 11 belows, the base 2 perpendicular to the circumference of follower gear 11, by 14 controls of a locking key; A side that on braking bar 8, contacts with locking key 14; One locating slot is arranged, and leading portion is with a compression spring 13, and the end is provided with a braking cushion rubber bumper 12; Locating slot on one braking clamp being arranged on the locking key 14 and braking bar 8 cooperates, and the front has a brake check spring 15 to withstand locking key 14.Be convenience of calculation, a small-sized function calculator 6 is installed on the base 2 of this instrument other end.
Pick up measuring instrument, eyes press close to amplify the eyepiece of telescope 1, amplify the middle cross point of telescope 1 and aim at the measured object measurement point; Press locking key 14; Compression spring 13 discharges, and braking bar 8 ejects under the effect of compression spring 13, withstands follower gear 11; Make dial needle 5 location, play braking action.Read 4 angles of display of index dial,, can calculate the distance and the height of measured object very soon the small-sized function calculator 6 on the survey numerical value input instrument.When measurement finishes, draw downwards moving bar 8, under the effect of brake check spring 15, the braking clamp on the locking key 14 is retracted into brake bar 8 positioning and lockings in the locating slot, in order to use next time.
