Description

Combined digital display measurer for steel rail flatness and frog point rail abrasion

Technical Field

The utility model relates to a railway equipment technical field especially relates to a steel rail straightness and frog point rail wearing and tearing combination digital display caliber.

Background

The rails are important parts of the track structure and play a role in guiding the wheels, supporting and transferring loads. Rail joints are classified into general joints, special joints, insulated joints, welded joints and frozen joints according to their properties. The rail surface of the common rail joint is uneven due to gaps, height difference among the rails, poor tamping and the like, and the common rail joint is locally bent downwards under the repeated impact of wheels to form a low rail joint. The cementation and freezing joints have the middle insulation piece strength lower than that of the steel rails, the rail gaps exist among the steel rails during freezing, the daily maintenance is not timely, and the like, and the low joints at the rail gaps are generated under the repeated impact of the wheels. Three diseases are easily generated on the welding seam of the welding joint, one is that the rail surface of the steel rail is not rightly butted during welding to generate the height difference of the rail surface, and a pit is formed at the lower end of the steel rail during rolling; the other is that the hardness of the welding seam is lower than that of the steel rail, the welding strip can form a depression along with rolling of train wheels, and the third is that the daily maintenance is not in place or the grinding is not timely performed to form the depression by rolling of the wheels. The low joint and the welding seam of the steel rail are sunken, and the steel rail is easy to break under the long-term action of train load, thereby bringing great hidden trouble to the train safety. At present, the flatness measurement of the railway steel rail is mainly divided into two types, one type is a digital measuring instrument adopting a sensor, and although the measuring instrument has high precision and high price, the measuring instrument is not convenient to carry and cannot be generally popularized. And in addition, the simple measurement of the combination of the ordinary flat ruler and the feeler gauge is utilized, the measurement is low in precision, and the data accumulation of the feeler gauge by workers on site is very troublesome.

The switch frog is a track plane crossing device for making train wheels pass through one steel rail and the other steel rail, and is an important component of a track traffic switch. After the frog is used for a period of time, under the rolling and impact action of train wheels, the point rail can generate abrasion in different degrees. Fixed type frog divides whole cast frog and combination frog, does not have the special measuring tool of simultaneous measurement to two kinds of models frog at present, brings very big puzzlement for the circuit maintainer. Meanwhile, the measuring frog in the market is a special tool, and is very troublesome to bring to the field during field detection.

In conclusion, the steel rail straightness and frog point rail abrasion are combined, and the steel rail detection device has the characteristics of multifunctional detection, convenience for detection personnel to use, high measurement precision and the like.
