Abstract
The utility model relates to a rail ultrasonic flaw detection probe undercarriage, the device comprise big four-bar linkage, little four-bar linkage, big four-bar linkage servo spring, big four-bar linkage reset spring, little four-bar linkage servo spring, cylinder, box, adjustment gyro wheel, frame, are equipped with servo spring and reset spring on big four-bar linkage, are equipped with little four-bar linkage servo spring on little four-bar linkage, and little four-bar linkage connects the probe. The ultrasonic flaw detection device has the advantages that the ultrasonic flaw detection on-line automatic detection of the steel rail can be realized, the labor productivity is improved, and the ever-increasing requirements of users are met.
Description
Technical field
The utility model relates to a kind of undercarriage of reflectoscope.
Background technology
The pneumatic type probe undercarriage that present ultrasonic inspection online automatic detection is adopted, be that a kind of simple cylinder that leans on promotes probe bracket, a kind of take-off and landing device to rail carrying out horizontal position sensing, not only excessive because of putting forth effort, make probe fragile, and relatively poor because of the real-time servo-actuated effect of its horizontal direction, the shortcoming that the vertical direction servo-actuated does not almost have makes the rate of false alarm of probe higher.And the scanning zone at each position of new standard all has by a relatively large margin lifting than primary standard, determine according to probe emission sound field, flaw detection should detect from the tread of two sides and rail vertical direction, therefore adopts conventional at present probe undercarriage can't satisfy the requirement of new standard.
Summary of the invention
The purpose of this utility model provides a kind of rail flaw ultrasonic detection probe undercarriage, can realize the rail flaw ultrasonic detection online automatic detection, raises labour productivity, and satisfies the ever-increasing requirement of user.
For achieving the above object, the utility model is achieved through the following technical solutions:
Rail flaw ultrasonic detection probe undercarriage, it is characterized in that: this device is made up of big four connecting rods, little four connecting rods, big four connecting rod follower springs, big four connecting rod back-moving springs, little four connecting rod follower springs, probe, cylinder, casing, adjustment roller, support, cylinder connects big four connecting rods, on big four connecting rods, be provided with big four connecting rod follower springs and big four connecting rod back-moving springs, little four connecting rods connect big four connecting rods, on little four connecting rods, be provided with little four connecting rod follower springs, little four connecting rods connect probe, probe also connects adjusts roller, adjusts roller and is located on the heavy rail.
The beneficial effects of the utility model are: this device is finished by double-four link mechanism and is popped one's head in when detecting to the level of rail, the real-time servo-actuated and the tracking of vertical both direction, guarantees that testing process is stable, and the mistake omission when avoiding detecting takes place.The running orbit of double-four link mechanism is forever perpendicular to the rail surface, makes probe stressed evenly, is difficult for tumbling, nose, thereby guarantees that probe face is parallel to detected of rail forever.
Description of drawings
Fig. 1 is the structural front view of rail flaw ultrasonic detection probe undercarriage.
Fig. 2 is the structure side view of rail flaw ultrasonic detection probe undercarriage.
Embodiment
See Fig. 1, rail flaw ultrasonic detection probe undercarriage, this device is by big four connecting rods 7, little four connecting rods 4, big four connecting rod follower springs 6, big four connecting rod back-moving springs 11 (Fig. 2), little four connecting rod follower springs 5, probe 1, cylinder 10, casing 9, adjust roller 3, support 8 is formed, cylinder 10 connects big four connecting rods 7, on big four connecting rods 7, be provided with big four connecting rod follower springs 6 and big four connecting rod back-moving springs 11, little four connecting rods 4 connect big four connecting rods 7, on little four connecting rods 4, be provided with little four connecting rod follower springs 5, little four connecting rods 4 connect probe 1, probe 1 also connects adjusts roller 3, adjusts roller 3 and is located on the heavy rail 2.
The effect of probe 1 is emission, reception ultrasound wave.The effect of adjusting roller 3 is to limit and adjust the position of probe with respect to rail.The effect of cylinder 10 is to finish the power source that probe rises and falls.
The course of work of this device is: during line flaw detection,, rail falls when entering big four connecting rods 7 of surveyed area exhaust casing 10 drivings, and stretch big four connecting rod follower springs 6 and back-moving spring 11.Follower spring 6 is responsible for providing the real-time servo-actuated power of probe level in the rail operational process, and back-moving spring 11 is responsible for providing and is detected when finishing the big four connecting rods power that resets.Probe is fallen the rail surface when beginning to detect, and the follower spring 5 of little four connecting rods 4 is stretched, and vertical direction has when beating in the rail operational process, and little four connecting rod follower springs will provide probe real-time servo-actuated power.
