Abstract

The invention provides a grooved rail grinding device and method utilizing a curved surface grinding machine, relates to the technical field of rail grinding maintenance, and solves technical problemsthat existing grinding equipment cannot effectively grind a grooved rail, and maintenance and repair purposes are difficult to achieve. The grinding device comprises a curved surface grinding machine, and the curved surface grinding machine makes contact with a profile surface of the grooved rail through a circumferential surface of a grinding wheel and can carry out forward and reverse bidirectional grinding. The curved surface grinding machine comprises a first grinding unit, a second grinding unit, a third grinding unit and a fourth grinding unit. The first grinding unit, the second grinding unit, the third grinding unit and the fourth grinding unit are connected in sequence and can grind different positions of the profile surface of the grooved rail, and complete envelope grinding canbe performed on the profile surface of the grooved rail after combination. Grinding quality and efficiency are ensured through combination of the multiple grinding units, the maintenance and repair purposes are achieved, and a problem that a large grinding machine cannot carry out grinding due to a size reason is solved.

Description

technical field [0001] The invention relates to the technical field of rail grinding and maintenance, in particular to a groove rail grinding device and a grinding method using a curved surface grinding machine. Background technique [0002] As an extension of rail transit lines, trams have become an important part of urban rail transit lines due to their advantages of energy saving, environmental protection, safety and comfort, and more and more lines are being constructed and operated in many cities. Because the tram track line is horizontal to the road surface, grooved rails are used in order to match the tram wheels. The state of the grooved rail directly affects the running safety and comfort of the tram. At present, the most economical and effective way to maintain the grooved rail is to implement grinding. [0003] The quality of small grinding machines and manual grinding is uneven, the grinding efficiency is low, and the grinding areas are discontinuous. The mediu...
