Abstract

The invention provides a tread sweeper with a gap adjusting device, and belongs to the technical field of railway vehicle equipment. The tread sweeper comprises a grinding block, a brake head, an air cylinder and a gap adjusting device arranged on an air cylinder body of the air cylinder. The tread sweeper further comprises a tooth-shaped component is fixedly arranged on a piston rod of the air cylinder. The gap adjusting device comprises: a movable plug pin and a movable plug pin, wherein a plug pin head of the movable plug pin can be meshed with the tooth-shaped component; a bolt seat limited in a gap adjusting device mounting hole of the air cylinder body; and an elastic component used for applying downward pressure towards the tooth-shaped component to the bolt seat. The upper end of the movable plug pin is sleeved with a guide groove, formed in the moving direction of the piston rod, of the plug pin base and can move forwards and backwards in the gap adjusting device installation hole along the guide groove along with the tooth-shaped component meshed with the movable plug pin. The tread sweeper is simple in structure and good in reliability, and the problems of bending, clamping stagnation and the like of the tooth-shaped component are solved.

Description

technical field [0001] The invention belongs to the technical field of rail vehicle equipment, and relates to wheel tread cleaning of rail vehicles, in particular to a tread cleaner with a gap adjusting device. Background technique [0002] The tread cleaner is usually installed on the rail vehicle corresponding to the wheel of the rail vehicle, and it can controllably use the friction of the abrasive block (or "grinder") installed on it to act on the wheel tread, thereby producing a tread cleaning effect on the vehicle tread . The friction effect can keep the wheels and the track in a relatively good adhesion state, which is beneficial to avoid the problem of idling or sliding of the rail vehicle due to insufficient adhesion between the wheels and the track during the starting, decelerating or braking process. Therefore, the tread sweeper is one of the important components installed on the rail vehicle. [0003] In a conventional tread cleaner, as the cylinder continuousl...
