Abstract
The invention discloses a precision steel cable type digital display convergence gauge. The convergence gauge is composed of a retractable type aluminum alloy protection tube, a self-locking type universal hook, a light high-strength inhaul cable mechanism and a length digital display mechanism. The convergence gauge is characterized in that: the convergence gauge is integrally fixed at two measurement points by the self-locking type universal hook; and a steel cable which is protected by an aluminum alloy extension tube and supplied with reversed tension by a quasi constant force clockwork spring bypasses a reading device to precisely measure a distance between the two measurement points. The precision steel cable type digital display convergence gauge mainly has the advantages of convenience for use, high reliability, high precision, good sealing performance and strong implementability.
Description
Technical field
The invention belongs to the monitoring rock and soil engineering instrument field, particularly the peripheral convergence measurement instrument in Tunnel Engineering, underground chamber, the mine working STABILITY MONITORING.
Technical background
The convergence monitoring is the important component part of Geotechnical Engineering STABILITY MONITORING.Convergence gauge is as a kind of instrument of Geotechnical Engineering STABILITY MONITORING, in the Geotechnical Engineering construction, and widespread usage in Tunnel Engineering, underground chamber, the mine working especially.
The current convergence gauge that generally uses is generally stainless rule belt convergence gauge, because operator's pulling force difference causes the different amounts of deflection that produce, measuring error is bigger.And because underground structure is inner moist, make stainless rule produce corrosion easily, influence its long-term use.For patent 200910182325.5, it has applied for a kind of convergence gauge of micrometer caliper formula, and part has overcome the amount of deflection problem, yet its reading is complicated, and not seen widespread use is in stability convergence monitoring.
In order to overcome existing convergence gauge survey measurements difficulty, the low defective that reaches the water proofing property difference of reliable measurement degree,, designed this patent according to Calculation of Deflection and digital display technology.
Summary of the invention
The object of the present invention is to provide a kind of easy to usely, measure accurately, data are reliable, the cable type digital display convergence gauge of waterproof anti-corrosion.
For reaching the object of the invention, the technical scheme of employing is following:
A kind of accurate cable type digital display convergence gauge is characterized in that being made up of telescopic aluminium alloy pillar, the universal hook of self-locking, high-strength light drag-line mechanism, length digital display mechanism.
Introduce the concrete composition and the function of each several part below in detail:
1. telescopic aluminium alloy pillar is formed (can adopt different models such as 10,8,6,4 according to different tunnel structures) by some long 1.5 meters hollow tubes.
Minimum 30 millimeters of hollow tube internal diameter; 33 millimeters of external diameters increase progressively 3 millimeters respectively successively, and four direction has cross chute to keep the straight of aluminium alloy pillar and freely to stretch; And play the whole bendind rigidity of enhancing aluminium alloy pillar, reduce the effect of aluminium alloy pillar amount of deflection under action of gravity.Hollow tube adopts hermetically-sealed construction, effectively waterproof and protection reading device and cable wire.
2. two universal hooks of self-locking are installed in aluminium alloy pillar two ends, and gib head can be self-locking in the gib head of two measurement points of tunnel convergence monitoring, and can realize freely rotating, to guarantee that digital display instrument is towards survey crew.
3. high-strength light zip mechanism is that the accurate constant force clockwork spring of 20N is formed by high-strength light cable wire, the reversal interlocking relay of 2 millimeters of diameters, and an end of cable wire one end and steel pillar is fixed, and the other end is walked around roller and is connected with clockwork spring.Along with stretching of aluminium alloy pillar, cable wire can freely stretch under the counter pull effect of accurate constant force clockwork spring.
4. length digital display mechanism is made up of roller, gear mechanism, power supply, infrared emission and reception inductor, counter, digital display screen and lighting device.Along with stretching of aluminium alloy pillar, walk around roller in the cable wire telescopic process, drive roller and roll, roller is transferred to the porous roller through gear mechanism.The infrared emission and reception inductor that is installed in its two sides blocked in the rotation of porous roller.Infrared emission is counted with reception inductor linkage counter, shows at digital display screen.Lighting device is installed in and can makes things convenient in the underground structure reading under the dim environment on the digital display screen.
Advantage of the present invention is:
1. this convergence gauge adopts the design of external aluminium alloy pillar and fiber steel wire reading, and the measuring error that the different amounts of deflection of stainless rule produce when having avoided artificial stretching to cause measuring strengthens measuring reliability and precision greatly.
2. the native system good airproof performance has good anticorrosion water-proof function.
3. the technology of the present invention's application is all ripe, and realizability is strong.
