Portable self-adjustment wheel type probe bracket for rail flaw detecting car

Abstract

The invention relates to a portable self-adjustment wheel type probe bracket for a rail flaw detecting car, which belongs to the technical field of rail flaw detecting cars. The invention aims to provide a portable self-adjustment wheel type probe bracket for a rail flaw detecting car, which can enable the probe to be kept on the central line of the rail all the time and detect the rail state accurately. The portable self-adjustment wheel type probe bracket comprises front rail traveling wheels, rear rail traveling wheels, wheel axles, a chassis and a probe bracket, wherein the wheel axles are used for respectively connecting the front rail traveling wheels and the rear rail traveling wheels; the chassis is connected with the front and rear wheel axles; the probe bracket is connected between the front and rear wheel axles on the chassis, and provided with front and rear wheel axle connecting plates, a cantilever, an adjusting plate and a fixed plate; one front end and one side of the cantilever are respectively fixedly connected with the front and rear wheel axle connecting plates; the other ends of the front and rear wheel axle connecting plates are respectively connected with axial sleeves on the front and rear rail traveling wheels; both ends of the rear side of the cantilever are respectively fixedly connected with the adjusting plate and the fixed plate; the probe is installed between the adjusting plate and the fixed plate; and the front and rear wheel axles on the flange sides of the front and rear rail traveling wheels are respectively sheathed with a spring.

Description

technical field [0001] The invention relates to a portable rail flaw detection car with an automatic adjustment wheel probe bracket, which belongs to the technical field of rail flaw detection cars. Background technique [0002] At present, ultrasonic wheel probes have been widely used in rail flaw detection. However, the existing rail flaw detection vehicle simply fixes the wheel probe on the rail flaw detection vehicle. Since the gauge of the rail often changes, the wheel probe immediately follows the rail during the operation of the rail flaw detection vehicle. The deviation from the center line of the rail due to the change of the gauge makes it difficult for the wheel probe to accurately detect fatigue defects and welding defects within the rail head and rail waist (including near the joint), as well as rail bottom corrosion and crescent drop , rail head crushing and other damages. Contents of the invention [0003] The object of the present invention is to provide ...
