Manual wheel type steel rail ultrasonic flaw detection car

Abstract

The invention discloses a manual wheel type steel rail ultrasonic flaw detection car. The manual wheel type steel rail ultrasonic flaw detection car comprises a wheel underframe, a wheel type probe mounted between front and rear guide wheels of the wheel underframe, and an ultrasonic flaw detector mounted on the flaw detection car. A wheel axle between each guide wheel and the wheel underframe is sheathed with a spring; the wheel axles connected at two ends of the wheel type probe are mounted in axle holes formed in a probe fixing block and a probe adjusting block on two sides of the wheel underframe, the probe adjusting block is provided with a rectangular axle hole and a kidney-shaped mounting hole, the rectangular axle hole is adaptive to a flat wheel axle at one end of the wheel probe inserted into the axle hole, the probe adjusting block under the rectangular axle hole is provided with a threaded hole, two sides of the wheel underframe are respectively connected with a lateral plate inclined backwards from bottom to top through a lateral plate fixing block, and a water brush under the wheel underframe is connected with a water tank through a water pipe; and an ultrasonic flaw detector inclining platform is fixed between the two lateral plates above the water tank by screws, and the end parts of the two lateral plates are provided with hand rails of push hands in a penetration manner.

Description

technical field [0001] The invention relates to a manual wheeled rail ultrasonic flaw detection vehicle, which belongs to the technical field of rail flaw detection vehicles. Background technique [0002] At present, most of the rail ultrasonic flaw detectors installed on manual flaw detection vehicles use contact probes, also called ski probes. This kind of probe is directly in contact with the rail because the probe is pressed against the rail by a spring during detection. Therefore, when the probe slides over the depression on the surface of the rail or the joint between two rails, etc., the probe will often be stuck, and even cause the probe to be damaged, especially in places where the rails are severely worn, such as bends. The surface is not straight, but has a certain arc profile. Even if the ski probe is pressed by a spring, it cannot be attached to the rail well, and it cannot ensure that the ultrasonic wave is well coupled into the rail, so that it cannot guarante...

[0002] At present, most of the rail ultrasonic flaw detectors installed on manual flaw detection vehicles use contact probes, also called ski probes. This kind of probe is directly in contact with the rail because the probe is pressed against the rail by a spring during detection. Therefore, when the probe slides over the depression on the surface of the rail or the joint between two rails, etc., the probe will often be stuck, and even cause the probe to be damaged, especially in places where the rails are severely worn, such as bends. The surface is not straight, but has a certain arc profile. Even if the ski probe is pressed by a spring, it cannot be attached to the rail well, and it cannot ensure that the ultrasonic wave is well coupled into the rail, so that it cannot guarantee the sound of the rail. Perform efficient and reliable detection
