Description

Limiting detecting instrument

Technical field

The present invention relates to the surveying instrument technical field, the limiting detecting instrument of inside dimension such as particularly a kind of tunnel that is used to measure building structure inside dimension and shape, especially road and rail, hydraulic engineering culvert and shape.

Background technology

Along with lasting, the stable development of national economy, country all drops into huge fund and be used to build highway, railway and hydraulic engineering every year.In order to ensure construction quality, must monitor and check and accept engineering construction.The representational instrument that is used to carry out construction monitoring and examination at present is instruments such as the AMT3000 of Lycra company, PROFILER4000.These instrumental functions are many, the automaticity height, and the Data Post software function is powerful, but complex structure, complex operation costs an arm and a leg, and is difficult to popularize.The domestic company that has uses the direct driving laser stadimeter of step motor, and send instructions for the single chip machine controlling circuit system by portable computer, write down the stepping angle of step motor, the operation of control step motor and laser range finder, read range finding numerical value simultaneously, transfer back to portable computer then, the data received and the angle of motor stepping are stored and handled by portable computer, and by printer prints measurement result data or figure.This equipment must use with portable computer, and under this mal-condition in working-yard moist, that dust is serious, equipment failure rate height and stream time are short.

Summary of the invention

The object of the present invention is to provide a kind of external equipment that need not, delicate structure, compactness, easy and simple to handle, moistureproof dustproof, be easy to promote the use of, ranging is the limiting detecting instrument of 0.2-100 rice.

The objective of the invention is to be achieved through the following technical solutions: a kind of limiting detecting instrument is made of measuring head 1, U type body frame 21 and tribrach 28 three parts.Measuring head 1 inside is equipped with laser range finder 2 and lengthy motion picture shape lithium battery 3 side by side.Be separately installed with left side axle 4 and right axle 6 in measuring head 1 left and right sides center, Y-axis is concentric.Measuring head 1 can vertically revolve three-sixth turn.The left and right arms of U type body frame 21 is a cavity, is separately installed with left axle sleeve 5, right axle sleeve 7.Left arm cavity internal fixation is equipped with Elastic Contact ring 8, palm PC 10, driver 11, and the contactor swivel becket 9 that circles round is fixed on axle 4 outsides, a left side.In the right arm cavity, be installed with direct current generator 20, worm screw 18, worm gear 15, right axle 6 outsides are embedded with 4-40 cylindrical rare-earth permanent magnet 13 in the chamber.Direct current generator 20 is connected with worm screw 18 by shaft coupling 19.The side of worm gear 15 is fixed with soft iron ring 14, and rotary encoder 16 is installed in its center pit.Soft iron ring 14 constitutes the magnetic force frictional interlocks with rare-earth permanent magnet 13.The measurement axis of rotary encoder 16 is fixed by register pin 17 and right axle 6 and is concentric with Y-axis.U type body frame 21 belows are equipped with hollow rotary encoder 27 shells of worm gear 24, worm screw 22, direct current generator 23 and level.Be embedded with 4-40 cylindrical rare-earth permanent magnet 25 on the worm gear 24.Round bubble and the long bubble of high precision are installed on the tribrach 28.The detection axle of the hollow rotary encoder 27 of soft iron ring 26 and level is installed on its vertical pivot.Soft iron ring 26 constitutes the magnetic force frictional interlocks with rare-earth permanent magnet 25.21 integral installations of U type body frame can horizontally rotate 360 ° on tribrach 28.Measuring head 1 flexibly connects with U type body frame 21 by left side axle 4, right axle 6 and left axle sleeve 5, right axle sleeve 7.Regulate measuring head connecting link 29 by manual fine-tuning screw rod 12, can regulate measuring head 1 position up and down.The data line of the both positive and negative polarity of lithium battery 3 and laser range finder 2 is connected with the contactor swivel becket 9 that circles round, and by Elastic Contact ring 8 electric power is offered palm PC 10, driver 11 and vertical rotary direct current electric motor 20 and horizontally rotates direct current generator 23.The data line of laser range finder 2 is also linked palm PC 10 by the contactor swivel becket 9 that circles round simultaneously.When direct current generator 20 rotated, direct current generator 20 drove worm screw 18, drove worm gear 15 rotations.The rotation of worm gear 15 is by friction force drive right axle 6 and measuring head 1 rotation of soft iron ring 14 with the magnetic attracting of rare-earth permanent magnet 13.Right axle 6 driven rotary scramblers 16 rotate synchronously with measuring head 1.Rotary encoder 16 is passed to palm PC 10 and driver 11 with the anglec of rotation data that detect.When direct current generator 23 rotated, direct current generator 23 drove worm screw 22, drove worm gear 24 rotations.The rotation of worm gear 24 is by friction force drive U type body frame 21 rotations of rare-earth permanent magnet 25 with the magnetic attracting of soft iron ring 26.When power that manual wheel measuring head 1 applies during greater than the friction force of the magnetic attracting between rare-earth permanent magnet 13 and the soft iron ring 14, measuring head 1 can rotate arbitrarily.When manually horizontally rotating power that U type body frame 21 applies greater than the friction of the magnetic attracting between rare-earth permanent magnet 25 and the soft iron ring 26, U type body frame 21 can rotate arbitrarily.By operation palm PC 10, driver 11 is by the programmed control direct current generator of setting 20,23,

drive measuring head

1 and 21 rotations of U type body frame, and the vertical anglec of rotation of measuring distance and measuring head 1 and U type body frame 21 horizontally rotate angle, and the distance that will measure and angle-data show and storage with figure and form on the screen of palm PC 10.

This limiting detecting instrument is specially adapted to the construction monitoring and the examination of the tunnel and the hydraulic engineering culvert of highway, railway, also can be to the distortion measurement of longspan structure thing Ru Qiao, beam etc.

The present invention has following good effect:

Compact conformation of the present invention, exquisiteness need not any external equipment and just can work.But both the motor-driven measuring head vertical, horizontally rotate measurement, also at hand measuring head vertical, horizontally rotate measurement; Both can measure the gauge that this instrument sets up the cross section, place, and also can measure this 100 meters gauges in instrument front and back, and can do the gauge indication, as work such as installing and locating, borehole indications with cross section, interior distant place.Easy to operate, flexible, and volume is little, in light weight, is easy to carry, for survey crew provides great convenience.Ranging is a 0.2-100 rice.
