Problems solved by technology

[0004] Therefore, the technical problem to be solved by the present invention is that the uncut area or part of the airway in the existing carbon skateboard is not easy to be damaged and leak air, so that when the carbon skateboard is deformed, the automatic lowering bow protection device does not start. Damaged carbon skateboard continues to be used causing serious pantograph-catenary accident

Embodiment 1

[0034] This embodiment provides a helical wire cutting device for the outer circular surface of the airway, including: a bracket body 1; a drive assembly 2, which is arranged at one end of the bracket body 1, and the drive assembly 2 is provided with a rotation mechanism for fixing the airway 3; Part 4, the rotating part 4 drives the air passage 3 to rotate by the motor on the drive assembly 2; the cutting wheel assembly 5 is slidably arranged on the bracket body 1, and the cutting wheel assembly 5 is set There is a cutter wheel 6, which cuts the radial direction of the air passage 3, and the angle between the cutter wheel 6 and the axis of the air passage 3 is set at a non-right angle; The channel is mostly a metal tube structure. However, due to the good toughness of the metal tube, when the carbon slide is deformed, it is not easy to damage and leak air in the uncut area or part of the cut area of ​​the air channel, so that when the carbon slide is deformed, the bow will be ...

Abstract

The invention provides an air way outer circle face spiral wire cutting device which comprises a support body, a driving assembly and a cutting tool wheel assembly. The driving assembly is arranged atone end of the support body and is provided with a rotating part used for fixing an air way, and the rotating part drives the air way to rotate by itself through a motor on the driving assembly. Thecutting tool wheel assembly is arranged on the support body in a sliding manner and is provided with a cutting tool wheel, the cutting tool wheel is used for cutting the air way in the radial direction, and the included angle between the cutting tool wheel and the axis of the air way is arranged to be in a non-straight-angle manner. The above spiral wire cutting device is provided, the problems that the tail cutting area or part of the cutting local of the air way in an existing carbon sliding plate is not likely to be subjected to breaking and gas leakage, when the carbon sliding plates is deformed, an automatic bow lowering protection device is not started, the damaged carbon sliding plate is used continuously, and serious bow net accidents are caused are solved.

Description

technical field [0001] The invention relates to the field of rail transit and the field of electrified railway technology, and mainly relates to a spiral cutting device and a cutting method for the outer circular surface of an airway. Background technique [0002] Pantograph carbon slides are used in rail transit rolling stock, such as high-speed trains, electric locomotives, subways and other vehicles, installed on the roof, in contact with the overhead power grid and conducting current for the vehicles. As described in the Chinese patent (publication number 2799313Y), the currently widely used carbon skateboard mainly includes carbon strips, air channels, and metal brackets, which are bonded and compounded by an adhesive to form a whole. The carbon bar is a brittle material, which is easy to be damaged during use. The air channel is arranged inside it, so that when the carbon bar and the slide plate are damaged under certain working conditions, the air channel will be dama...
