Steering frame of railway track car with flaw detection devices

Abstract

The invention discloses a steering frame of a railway track car with flaw detection devices, which comprises a framework, the upper part of the framework is provided with a traction seat connected with a car body through a traction device; the lower part of the framework is provided with an elastic node seat which is connected with a shaft box body through an elastic node; the shaft box body is connected with wheel pairs; a support spring arranged on the framework, a horizontal shock absorber and a two-system vertical shock absorber form a two-system suspension system of the car body; a shaft box spring with one end supported at the upper part of the shaft box body and the other end supported at the lower end of the framework and a one-system vertical shock absorber arranged on the framework form a one-system suspension system of the car body; the end part of the framework is provided with a unit brake; the shaft box body is provided with flaw detection devices arrange at intervals along the direction of steel tracks; and detection wheels of the flaw detection devices are in direct contact with steel tracks between the wheel pairs. According to the invention, the manufacturing cost is lowered, the shock of the detection wheels is reduced, the flaw detection accuracy rate is improved; moreover, the steering frame has the advantages of good operation quality is good, high pass curve performance, small horizontal force of wheel tracks, reliable braking performance and great convenience in maintenance and can completely meet the requirement of steel track flaw detection with high flaw detection speed.

Description

technical field [0001] The invention belongs to the technical field of railway rail cars, in particular to a railway rail car bogie with a flaw detection device. Background technique [0002] Existing railway rail flaw detection is completed by a flaw detection trolley installed at the lower part of the railway rail car body. During operation, the trolley equipped with a flaw detection system device is hung under the frame, and there is a guard rail slider on the flaw detection trolley to control The position of the detection wheel on the rail during operation; since the trolley will vibrate with the vibration of the car body during operation, the stability of the flaw detection trolley is poor, and the vibration of the detection wheel is large during work, resulting in a low accuracy rate of damage detection in rail flaw detection. It can meet the flaw detection speed requirement of 60 km / h, and the centrifugal force of the vehicle is large when running at high speed. The f...

[0002] Existing railway rail flaw detection is completed by a flaw detection trolley installed at the lower part of the railway rail car body. During operation, the trolley equipped with a flaw detection system device is hung under the frame, and there is a guard rail slider on the flaw detection trolley to control The position of the detection wheel on the rail during operation; because the trolley will vibrate with the vibration of the car body during operation, the stability of the flaw detection trolley is poor, and the vibration of the detection wheel is large during work, resulting in a low accuracy rate of damage detection in rail flaw detection. It can meet the flaw detection speed requirement of 60 km / h, and the centrifugal force of the vehicle is large when running at high speed. The flaw detection trolley installed in the center of the lower part of the car body will generate centrifugal force when the vehicle passes through the curve and the turnout. The guard rail slider on the trolley is affected It has a strong impact and is easily damaged, which affects driving safety, so it is necessary to improve
