Problems solved by technology

[0002]At present, for the flaw detection of railway wheels, whether it is domestic artificial ultrasonic detection or foreign falling-wheel ultrasonic flaw detection for dismantling wheelsets, it takes a lot of manpower, Physical strength and detection time
Moreover, there are still the following problems in the actual operation process: in order to complete a comprehensive ultrasonic flaw detection of the rim and spoke, it is necessary to place multiple ultrasonic detection probes on the wheel tread and the inner surface of the rim, and the space requirements for the probe carrier are relatively large
However, there are obstacles such as gearboxes, brake discs, and sand-spraying pipes under the wheels of the EMU, and the space available for automatic ultrasonic testing is very limited; the space under the bogie is small, and it is difficult for the probe to enter under the tread of the wheels.
In similar situations in foreign countries, the only option is to give up the flaw detection of wheel sets in narrow spaces, which is extremely detrimental to the safety of railway traffic.

Embodiment 1

[0022] Such as Figure 1~6 As shown, the telescopic probe carrier of the present invention includes a probe 1 , and the probe 1 is fixed on the probe carrier 2 .

[0023] The above-mentioned probe carrier 2 is composed of a motor 3, a gear 4, an arc rack 5, a movable arc plate 6, a fixed arc plate 12 and a beam 7, 13, the motor 3 is fixed on the fixed arc plate 12, and the arc teeth The bar 5 is fixed on the movable arc-shaped plate 6, the gear 4 is installed on the shaft of the motor 3, and meshes with the arc-shaped rack 5, the two movable arc-shaped plates 6 and the beam 7 are connected to form a movable frame, and the two fixed arc-shaped The plate 12 and the crossbeam 13 are connected to form a fixed frame, the probe 1 is fixed on the crossbeam 7, 13, and is attached to the wheel tread 8, and the movable arc-shaped plate 6 has an arc-shaped guide groove 9, and there is a guide block in the arc-shaped guide groove 9 10. The movable frame and the fixed frame are connected ...

Embodiment 2

[0030] The telescopic probe carrier of the present invention, except that the driving device of the telescopic movement of the probe carrier 2 is a rotating cylinder, there is a guide block 10 in the arc guide groove 9, and there are 12 probes 1 on each probe carrier 2, the rest are all the same as Example 1 is the same.

Embodiment 3

[0032] The telescopic probe carrier of the present invention is the same as that of Embodiment 1 except that the driving device for the telescopic movement of the probe carrier 2 is a hydraulic motor, and there are 23 probes 1 on each probe carrier 2 .

The telescopic type probe carrier comprises a probe wThe invention belongs to the technical field of detecting devices of railway wheels, and in particular relates to a telescopic type probe carrier. The telescopic type probe carrier comprises a probe which is fixed on the probe carrier. The telescopic type probe carrier has the advantages of reasonable design, convenient use, debugging and maintenance and high detection coverage rate and accuracy,hich is fixed on the probe carrier. The telescopic type probe carrier has the advantages of reasonable design, convenient use, debugging and maintenance and high detection coverage rate and accuracy,saves large quantities of manpower, material resources and detection time expensed by the drop type ultrasonic flaw detection, and guarantees the traffic safety of the railway.saves large quantities of manpower, material resources and detection time expensed by the drop type ultrasonic flaw detection, and guarantees the traffic safety of the railway.

Description

Technical field: [0001] The invention belongs to the technical field of detection devices for railway wheels, and in particular relates to a telescopic probe carrier. Background technique: [0002] At present, for the flaw detection of railway wheels, whether it is domestic artificial ultrasonic detection or foreign wheel set dismantling ultrasonic flaw detection, it takes a lot of manpower, material resources and testing time. Moreover, there are still the following problems in the actual operation process: in order to complete a comprehensive rim and spoke ultrasonic flaw detection, it is necessary to place multiple ultrasonic detection probes on the wheel tread and the inner surface of the rim, and the space requirements for the probe carrier are relatively large. However, there are obstacles such as gearboxes, brake discs, and sand-spraying pipes under the wheel sets of the EMU, so the space available for automatic ultrasonic testing is very limited; the space under the...
