Abstract
The utility model relates to a detection tool, in particular to a composite digital track gauge special for detecting the distance and the relative height difference between railway steel rails. The composite digital track gauge comprises a gauge body, a fixed end and a movable end. The composite digital track gauge is characterized in that: the fixed end and the movable end are formed at two ends of the gauge body, and the detected face contact positions of the fixed end, the movable end and the steel rails are in convex sphere structures; a capacitive displacement sensor, an electronic liquid swing inclination angle sensor and a data processing module are arranged in the gauge body; and the capacitive displacement sensor is rigidly connected with the movable end through a spring/connecting rod structure. The measured part is in point contact with the tested face, so a measurement mis-registration G value caused by steel rail flanging can be avoided; due to the capacitive displacement sensor, the electronic liquid swing inclination angle sensor and the data processing module, acquisition, calculation, storage and display of the measured data are quick and accurate, and the cost performance is high; and the measurement unit and the data processing module are concealed in the gauge body in an embedded mode, so the appearance is tidy, and the rainproof performance is good.

Background technology
Like product begins to use at railway working system at present, and has the good prospect that replaces mechanical gauging rule.The defective that haves much room for improvement is: 1. when rail is subjected to vehicle wheel rolling presses flange to occur, and the column type metering contact of like product, and the G value is appearred between the side, cause the measurement misalignment; 2. selected cost performance displacement transducer improperly for use, the product cost is too high, and influence is promoted; 3. continued to use the blade structure of mechanical gauging rule, rainproof, the barrier propterty and the outward appearance of product are relatively poor.
Summary of the invention
The utility model is intended to solve the problems referred to above that background technology exists, and provides a kind of easy to operate, quick, can set up corresponding data link, the compound digital gauging rule that combination property significantly improves.
The technical scheme that the described problem that solves the utility model adopts is: a kind of compound digital gauging rule, comprise blade, stiff end, movable end, it is characterized in that, described stiff end and movable end are installed in the blade two ends, and this stiff end and movable end and rail tested surface contact position are the convex spherical structure; Capacitive displacement transducer and electronics liquid pendulum obliquity sensor and data processing module are housed in the described blade, and this capacitive displacement transducer is by spring/bar linkage structure and movable end rigid connection.
Compared with prior art, the utlity model has following three characteristics:
1. different with the column type metering contact of like product, the measuring point of the utility model stiff end and movable end adopts the convex spherical designs, has realized contacting with the point of tested surface the measurement misalignment G value that can avoid invar rail flange to cause.
2. different with the displacement transducer of like product, core technology of the present utility model is capacitive displacement transducer+electronics liquid pendulum obliquity sensor+data processing module, gather, calculate, store, show that measurement data fast, accurately, the cost performance height, especially making the capacitive displacement transducer of less expensive be used for gauging rule becomes possibility.
4. the blade structure with like product is different, and measuring unit of the present utility model and data processing module are built in the blade with embedded mode, and outward appearance is clean and tidy, and water-resistant performance is good.
