Line moves, and certainly, concrete transform mode is not limited to above citing.Sliding part 413 can be such as figure institute
Showing and include two groups, each connecting shaft two ends are sheathed in the sliding part 413 of a group, so, sliding part 413
With connecting shaft along with arc track move time, there occurs oscillating motion, as long as making flaw detection wheel 30 and sliding part
413 and/or connecting shaft etc. synchronize to swing, just can realize the swing of flaw detection wheel 30, wherein, such as Fig. 6
Described, the second pushing block 416 also can be set and realize the transmission between connecting shaft and connecting rod 412.Implement in diagram
In example, sliding part 413 and/or connecting shaft are affixed with the first plate 414 of signal in figure, the first plate 414
Flaw detection wheel 30 can be mounted directly by mounting assembly and required parts are installed, in the illustrated embodiment, the
One plate 414 is connected to vertical adjustment mechanism 42, is connected with flaw detection wheel 30 by it, so, flaw detection wheel
30 and vertical adjustment mechanism 42 together realize swing rotary, on this basis, moreover it is possible to by vertical adjustment machine
Structure 42 realizes vertical regulation, and how relevant vertical adjustment mechanism 42 realizes, the most unfolded.
Refer in the embodiment of Fig. 4 to Fig. 6 signal, described centering subsystem includes level(l)ing mechanism 41
With vertical adjustment mechanism 42, described level(l)ing mechanism 41 is in order to described along the direction regulation being perpendicular to rail
The horizontal level of flaw detection wheel 30；Described vertical adjustment mechanism 42 is in order to regulate the vertical of described flaw detection wheel 30
Position.
Relevant described level(l)ing mechanism 41, it includes horizontal adjustment motor 430, slide block structure 431 and slides
Rail 432, drives described slide block structure 431 to move along slide rail 432 by horizontal adjustment motor 430.Tool
For body, horizontal adjustment motor 430 exports rotary motion, by feed screw nut assembly, rack and pinion assembly
Etc. mode, be translated into linear motion, and then drive slide block structure 431 to move along slide rail 432.As
What makes the movement of slide block structure 431 move with the level of synchronization of flaw detection wheel 30, and alternative of the present invention has
Many possibilities.In the illustrated embodiment, it is by driving angle adjusting mechanism 41 indirectly to drive vertical adjustment
Mechanism 42, the final flaw detection wheel 30 driven under vertical adjustment mechanism 42 moves horizontally.The most concrete
For, angle adjusting mechanism 41 includes that connecting plate 415, arc track 410 are located at connecting plate 415, even
Fishplate bar 415 and slide block structure 431 is fixing to be connected, it is achieved synchronous slide, further for, horizontal adjustment
Motor 430 can drive the movement of slide block structure 431 by the first pushing block 433.
For the relation of angle adjusting mechanism 41 with level(l)ing mechanism 43, also need supplementary notes, the present invention
The embodiment of diagram also introduces installing plate assembly 45, and it is installed on vehicle frame 1, angular adjustment motor 411
Be mounted on installing plate assembly 45 with horizontal adjustment motor 430, including corresponding feed screw nut assembly or
Rack and pinion assembly etc., it is possible to be installed on installing plate assembly 45.Further in alternative, installing plate
Assembly 45 can include the first installing plate and the second installing plate, and horizontal adjustment motor 430 is installed on the first peace
Dress plate, angle adjusting mechanism 41 is installed on the second installing plate, and horizontal adjustment motor 430 drives slide block structure
431 when moving horizontally, and synchronizes to drive angular adjustment motor 411 to do and moves horizontally accordingly, to ensure at angle
Degree adjusts motor 430 when not working, angle adjustment motor 411, connecting rod 412 and connect company thereon
Spindle, the second pushing block, feed screw nut assembly, all do the movement synchronized.
Relevant described vertical adjustment mechanism 42, described vertical adjustment mechanism 42 includes set screw 420, institute
The vertical position regulation stating flaw detection wheel 30 is realized by described being pre-adjusted of set screw 420.Specifically
For, vertical adjustment mechanism 42 also includes the second plate 421 and the 3rd plate 422, passes through set screw
420 can regulate the position relationship between first plate the 414, second plate 421 and the 3rd plate 422,
Thus realizing vertical adjustment, flaw detection wheel 30 and mounting assembly thereof are installed on the 3rd plate 422, certainly,
Set screw 420 also can adjust the mounting assembly etc. of flaw detection wheel further relative to the second plate 421 and the 3rd
Position between plate 422, if the adjustment achieved between plate, in other words eventually through set screw
The rotation of 420 achieves the vertical position regulation of flaw detection wheel 30, it is simply that the optional scheme of the present invention.
Visible centering subsystem can guarantee that the regulation of the flaw detection wheel 30 of ultrasound wave controls, and makes flaw detection wheel 30 independent
Axially moving left and right in directive wheel 61, radially swinging relative to rail rail level；By adjusting in advance
Joint set screw 420 realizes vertical regulation, and make the flaw detection of ultrasound wave take turns 30 has certain pressure to rail surface
Clamp force, it is ensured that ultrasound wave is visited wheel and rail surface centering and coupled well.
By illustrating in detail above, the concrete structure how realized in centering subsystem 4 of the present invention is carried out
Illustrate, but the design of the present invention, the implementation of three kinds of motions is not limited to this, is more than to the present invention
