Description
Technical field
The utility model relates to a kind of electric railway checkout equipment, relates in particular to a kind of portable contact line conducting wire abrasion measuring instrument.
Background technology
At present, the measurement of electrification railway contact net lead abrasion mainly contains following dual mode: 1, inspection vehicle is measured: mainly take import as main, China starts late on the one hand at this, and is technical still immature.The shortcoming of using inspection vehicle to measure: on the one hand, price external or domestic inspection vehicle is all quite expensive, and complex structure is difficult to popularize and spread; On the other hand, it is interval that inspection vehicle need take driving, upsets the railway dispatching service chart, and online the detection needs United Dispatching, so to some extent inconvenience on using.2, vernier caliper manual measurement, for a long time, China railways basic unit mainly uses the abrasion of vernier caliper manual measurement contact net, and this mode labour intensity is large, efficient is low, sense cycle is long, image data is few, is difficult to adapt to the needs of modern electric railway high speed development.It is 99244590.6 that prior art discloses the patent No., and patent name is Portable tranverse abrasion charged remote sensing instrument, discloses a kind of Portable tranverse abrasion charged remote sensing instrument, and it is comprised of optical texture, circuit structure and physical construction.The DATA REASONING of this device is mainly processed to finish by optical texture and ccd image, optical texture is comprised of illuminator and imaging system again, illuminator and imaging system are made of other complicated mechanisms again, cause physical construction, Circuits System and the ccd image data processing aspect of this device all very complicated, add this device exterior design unreasonable, thereby cause on-the-spot application inconvenience, image data to be difficult to accurately.Therefore no matter be expensive foreign technology or equipment, or first domestic existing technology, all can not solve well in the electrification railway contact net lead abrasion routine testing an easily and efficiently difficult problem.
Summary of the invention
The purpose of this utility model is to provide a kind of portable contact line conducting wire abrasion measuring instrument, and it has simple in structure, measures accurately advantage easy to use.
The utility model is achieved like this, it comprises High-Voltage Insulation bar connector, front panel, battery case, the measuring instrument display panel, locating piece, spacing head, baffle plate, measuring head, the axis of guide, power switch and button, the upper end that it is characterized in that High-Voltage Insulation bar connector is fixedly connected on the downside of front panel, front panel is provided with measuring instrument display panel and button, the both sides of front panel are connected with respectively battery case and power switch, the two ends of the upper side of front panel are connected with respectively locating piece and the axis of guide, locating piece connects baffle plate, baffle plate is connected with spacing head, the upper end of the axis of guide is fixedly connected with measuring head, the end of measuring head be positioned at spacing head under.
Technique effect of the present utility model is: the utility model measuring method is simple, reliable, and measuring accuracy is high, and insulating bar is withstand voltage to be reached more than the 27.5KV, can live line measurement.And Design of Mechanical Structure is simple, firm, safe and reliable, and is lightweight, is easy to carry; This measuring instrument has higher cost performance, and is small and exquisite flexible, powerful, saved manpower and materials than vernier caliper manual measurement; Saved substantial contribution than the inspection vehicle measurement; Measurement is simple, reliable indirectly than other noncontacts, easy operating.The use of this measuring instrument tallies with the national condition, and is particularly suitable for the measurement of electric railway basic unit highway section contact line conducting wire abrasion, is suitable for large-scale popularization and uses, and succeeding in developing of this instrument has great economic implications and social effect to the China railways cause.
