The invention discloses a stay cable type displacement meter calibration device, which comprises a base, a slide caliper main scale, a vernier, a thread clamping bolt, a limit pulley, a crank handle, a kinking wheel, a connection seat and a fastening bolt. The slide caliper main scale is fixedly arranged on the base; the kinking wheel and the crank handle are fixedly arranged on the end part of the base through the connection seat; the thread clamping bolt is fixed on the vernier and is provided with a small through hole; and the limit pulley is fixedly arranged between the thread clamping bolt and the kinking wheel. By adopting the high-precision mechanical type slide caliper, the precision of the stay cable type displacement meter calibration device reaches up to 0.02 mm which is higher than that of a stay cable type displacement meter, and through a cyclical operation of the thread clamping bolt and the vernier, the invention can calibrate a stay cable longer than 10 m by the slide caliper with a 300 mm measuring range; moreover, the calibration device has simple and reasonable structure, high precision and convenient operation, solves the calibration problems of high-precision and large measuring range of the stay cable under a stretching working state, and is suitable for the indoor and outdoor calibration of the stay cable displacement meter.
Description
Technical field
The present invention relates to a kind of caliberating device of stay cable type displacement meter, be applicable to that the indoor and outdoor of stay cable type displacement meter is demarcated, belong to instrument class.
Background technology
China be one vast in territory, the mountainous region that topography and geomorphology is complicated and changeable, the increasing of building dynamics along with China traffic infrastructure is particularly along with the enforcement of strategy to develop western regions, the mountainous area highway construction is more and more, has the stable problem of high slope inevitably at the mountain area building highway.In case highway high slope unstability will be buried highway, will smash roadbed and bridge fine strain of millet, suspend traffic, causes driving accident, cause personal injury that economic loss and social influence are very big.Therefore, strengthen that the monitoring and the early warning in time of highway high slope are had great social significance and economic benefit.
Side slope surface displacement monitoring is one of most important form of slope monitoring.The method of surface displacement monitoring is more, but diverse ways respectively has its characteristics and the scope of application.The common total powerstation that utilizes carries out photoelectric measurement, needs artificial field observation, time and effort consuming, and affected by environment, personal error is bigger.Utilize Global Positioning System (GPS) (GPS), can realize long-range automatic monitoring in theory, but because the instrument costliness, and be difficult for scene protection, also be manually to carry instrument to carry out in-site measurement usually.More than two kinds of methods be difficult for all realizing long-range automatic monitoring that under particular surroundings and weather conditions, as heavy rain ice and snow etc., can't obtain Monitoring Data in real time, exactly side slope is the most dangerous monitoring that needs most in this case.Stay cable type displacement meter utilizes the automatic trigger pip of the stretching of drag-line, need not manually to obtain, can after handling, acquisition terminal utilize wireless transport module data to be sent to the in-house network of China Mobile, data are sent on the monitoring central server end main frame that is positioned on the Internet by China Mobile's communication network by the GPRS service node then, automatically analyze by software, in time issue early warning information, thereby realize remote real-time monitoring, and its precision can reach 1mm, and expense is relatively also relatively more cheap.But for the demarcation of stay cable type displacement meter, because the length of drag-line can reach 4-10m, precision is at 1mm, and requires to demarcate when drag-line pulling work, still do not have suitable caliberating device and scaling method at present.
Summary of the invention
At above-mentioned existing problems, the object of the present invention is to provide the device that is used for stay cable type displacement meter calibration, this device can be demarcated the measuring accuracy of stay cable type displacement meter.Its technical solution is:
Stay cable type displacement meter calibration device, it is by pedestal (1), vernier caliper main scale (2), vernier (3), card line bolt (4), spacing pulley (5), wind (6), winding wheel (7), Connection Block (8) and fastening bolt (9) constitute.Vernier caliper main scale (2) is fixedly mounted on the pedestal (1), the Winder of being made up of winding wheel and wind is fixedly mounted on pedestal (1) end by Connection Block (8), card line bolt (4) is fixedly mounted on the vernier (3), card line bolt (4) has the perforation aperture, aperture parallel axes vernier caliper main scale (2) is installed with spacing pulley (5) between card line bolt (4) and winding wheel (7).
The axis of described card line bolt (4) aperture and the pulley groove of spacing pulley (5) are on same axis.
At the bottom of the axis of described card line bolt (4) aperture and the pulley groove of spacing pulley (5) on same level height.
Described Connection Block (8) top is provided with fastening bolt (9).
Owing to adopted above technical scheme, the present invention has the following advantages and effect: adopting vernier caliper is the high-accuracy mechanical formula, and precision is higher than the precision of stay cable type displacement meter up to 0.02mm; By the cycling of card line bolt and vernier, can be at the drag-line of demarcating on the vernier caliper of 300mm range more than the 10m; Hand-rail type pulling mode is beneficial to the displacement of stably controlling drag-line; Overall volume is little, and is in light weight, portable.This caliberating device is simple and reasonable, and the precision height is easy to operate, has solved the demarcation problem of high precision, wide range when drag-line is in the stretching duty, is applicable to that the indoor and outdoor of stay cable type displacement meter is demarcated.

Embodiment
With reference to the accompanying drawings the present invention is described in further detail below:
According to Fig. 1 as can be known, this stay cable type displacement meter calibration device is by pedestal 1, vernier caliper main scale 2, and vernier 3, card line bolt 4, spacing pulley 5, wind 6, winding wheel 7, Connection Block 8 and fastening bolt 9 constitute.
The stay cable type displacement meter calibration device principle of work:
To stay cable type displacement meter calibration the time, at first with stay cable type displacement meter by being bolted to the pedestal tail end, its rear portion connects the digital signal display, external 2 joint 3V common batteries, the drag-line pulling promptly can produce displacement signal and be presented on the digital signal display, is unit with mm.The free end of drag-line passes card line bolt aperture, walks around spacing pulley and is fixed on the winding wheel, and the drag-line outlet remains on the same level height with the axis that blocks aperture in the line bolt and the bottom land of spacing pulley.Vernier is placed start position (0mm place), and the bolt on the tightening card line bolt tube wall is fixed together drag-line and card line bolt.By shaking wind winding wheel is rotated, drive drag-line and produce and stretch, drag-line drives card line bolt and vernier simultaneously and does and be synchronized with the movement, and the distance that drag-line moves is exactly the distance of vernier slip.The reading that reads on the slide calliper rule can get the vernier sliding distance, and the numeral that reads on the digital signal display can get the distance of drag-line pulling, and both compare the measuring accuracy that can demarcate stay cable type displacement meter.After vernier slides into 300mm (being the maximum range of vernier caliper), can be by tightening fixedly winding wheel of fastening bolt, thus drag-line is not bounced back, unclamp the bolt on the card line bolt again, will block line bolt and vernier and return reference position.Process above repeating, next section 300mm length that can demarcate drag-line.The total length of the drag-line of stay cable type displacement meter is 4m, can all demarcate by cycling and finish.
