Description
The invention discloses a kind of length of backguy mechanical drive output electric weight, the method for sensing of measurement of angle; A kind of length, angular transducer of backguy mechanical drive output electric weight are disclosed simultaneously.The invention belongs to field of measuring technique.
At present, the apparatus that can directly or indirectly measure length and angle is a lot, as various chi classes (as ruler, tape measure, milscale, protractor etc.), optical instrument class (as transit, infrared ambulator etc.), ultrasonic meter and radio wave measurement instrument etc.Length, measurement of angle apparatus that these are commonly used, the purposes that has is single, be subjected to environmental influence big, use inconvenient; Have cost an arm and a leg, volume is big, weight is big.When particularly in all kinds of mines tunnel or tunnel, carrying out the measurement of the relevant size of section, because the underground activities site surrounding all compares badly (for example insufficient light, high humidity, temperature is low, dust is many etc.), use various rulers directly to measure the relevant size of tunnel or tunnel cross-section (as profile height, width, area etc.) very inconvenient (for example do not see scale, data recording, the preservation of Chu's ruler all pretty troublesome etc.), the efficient of surveying work is reduced greatly.And optical measuring instrument, ultrasonic meter or radio wave measurement instrument etc., because of the price of these instruments all compares expensive, and volume and weight is all bigger, the tunnel country rock is uneven in addition, make the ultrasonic reflections directionality poor, underground insufficient light, temperature is big, dust is how very big to optical instrument measurement influence, underground electrical equipment running is serious to radio wave interference, causes these instruments to use in underground engineering survey and is restricted.For example: Beijing well construction technology research institute of Chinese coal research institute is with Switzerland grace cypress (AMBERG) 2000 profilers of 40,000 dollars of purchases, because what this instrument adopted is the infrared-type sensor, use proof through the scene, when this instrument uses in underground works, be subjected to the influence of temperature, humidity, light power bigger, unstable properties.
Therefore, should improve the efficient of underground survey work, make the performance of surveying instrument be subjected to the influence of environmental baseline as far as possible little again, reduce the cost of surveying instrument again, these all kinds of just underground engineering surveys press for the major issue of solution.
The objective of the invention is to design and a kind ofly can improve the simple in structure of surveying work efficient, with low cost, it is little influenced by environmental interference, the reliability height, volume is little, in light weight, be convenient to intelligentized, be specially adapted to all kinds of underground engineering constructions, construction quality is inspected for acceptance and is produced design, length under the more abominable condition of work such as ventilation network calculating, the method for sensing of measurement of angle and length that can operate as normal under this severe environmental conditions, angular transducer.
The length of the mechanical drive output electric weight that the present invention proposes, the method for sensing of measurement of angle, it is characterized in that: by the runner 2 of backguy 1 and backguy 1 drive, the rectilinear motion amount of backguy 1 of the tested length of reflection is converted to the circular motion amount of runner 2, and switching device (or equipment) A(by the circular motion amount can being converted to electric weight such as multiturn potentiometer etc.) change the circular motion amount of runner 2 into electric weight; It serve as spool to rotatablely move as circumference with a section (axis normal of this section is in pull-out direction of backguy 1) of right-angle bend 4 that above-mentioned backguy 1 by passing right-angle bend 4 drives right-angle bend 4, change tested angle the angle of the rotation of right-angle bend 4 into, and by the anglec of rotation being changed into switching device (or equipment) B(such as the multiturn potentiometer of electric weight) be electric weight with the angle change of right-angle bend 4 rotations.The variation of switching device (or equipment) A output electric weight has reflected tested length, and the variation of switching device (or equipment) B output electric weight has reflected tested angle.By switching device (or equipment) A is linked to each other not only energy measurement length and angle, and energy measurement area and volume with switching device (or equipment) B with calculating treatmenting equipment (as single-chip microcomputer or single card microcomputer disposal system).
The present invention is according to the length of above-mentioned a kind of backguy mechanical drive output electric weight, the thought of the method for sensing of measurement of angle, the length of the backguy mechanical drive output electric weight of design, angular transducer is by backguy 1, twine the runner 2 of backguy 1, with the runner 2 coaxial rotational potentiometers that connect 3, pass the right-angle bend 4 of backguy 1, be fixed on the driving wheel 5 on the right-angle bend 4 rotation axis AB, engaged wheel 6 with driving wheel 5 engagements, with the engaged wheel 6 coaxial rotational potentiometers that connect 7, one end returns and fixes on the other end on the runner 2 and be fixed on circle round clockwork spring 8 and bearing 10 on the bearing 9, bearing 11, bearing 12 is formed.See accompanying drawing one.
