Further specifically, angle adjustment motor 411 exports rotary motion, passes through feed screw nut component, rack-and-pinion
Component etc. mode is translated into linear motion, and then drive link 412 does flexible linear motion, certainly, specific to turn
Change mode is not limited to above citing.Sliding part 413 can include as shown in the figure two groups, and each connecting shaft both ends are sheathed on one
In the sliding part 413 of group, so, when sliding part 413 and connecting shaft are moved with arc orbit, pendulum motion has occurred, as long as
It is swung so that flaw detection wheel 30 is synchronous with sliding part 413 and/or connecting shaft etc., can realize the swing of flaw detection wheel 30, wherein
As described in Figure 10, the transmission between the second pushing block 416 realization connecting shaft and connecting rod 412 can be also set.In the illustrated embodiment, sliding
Moving part 413 and/or connecting shaft and the first plate 414 illustrated in figure are affixed, and the first plate 414 can be direct by mounting assembly
Component needed for installation flaw detection wheel 30 and its installation, in the illustrated embodiment, the first plate 414 is connected to vertical adjustment mechanism 42,
It is connect with flaw detection wheel 30 by it, so, flaw detection wheel 30 and vertical adjustment mechanism 42 realize swing rotary together, basic herein
On, moreover it is possible to vertical adjusting is realized by vertical adjustment mechanism 42, how related vertical adjustment mechanism 42 realizes, exhibitions further below
It opens.
It please refers in the embodiment that Fig. 8 to Figure 10 illustrates, the centering subsystem includes level(l)ing mechanism 43 and vertical
Regulating mechanism 42, the level(l)ing mechanism 43 is to along the horizontal position for adjusting the flaw detection wheel 30 perpendicular to the direction of rail
It sets；The vertical adjustment mechanism 42 to adjust it is described flaw detection wheel 30 vertical position.
The related level(l)ing mechanism 43 comprising Level tune motor 430, slide block structure 431 and sliding rail 432 lead to
Crossing Level tune motor 430 drives the slide block structure 431 to be moved along sliding rail 432.Specifically, Level tune motor 430 is defeated
Go out rotary motion, by feed screw nut component, rack and pinion assembly etc. mode, is translated into linear motion, and then drive
Slide block structure 431 is moved along sliding rail 432.How so that the movement of slide block structure 431 and the level of synchronization of flaw detection wheel 30 move, originally
Invention alternative has many possibility.In the illustrated embodiment, by driving angle regulating mechanism 41, driving is vertical indirectly
Regulating mechanism 42, it is final that the flaw detection wheel 30 under vertical adjustment mechanism 42 is driven to move horizontally.Further specifically, angle tune
It includes connecting plate 415 to save mechanism 41, and arc orbit 410 is set to connecting plate 415, and connecting plate 415 is fixed with slide block structure 431 to be connected
Connect, realize synchronous slide, further for, Level tune motor 430 can pass through the first pushing block 433 drive slide block structure
431 movement.
For the relationship of angle adjusting mechanism 41 and level(l)ing mechanism 43, also need to remark additionally, the reality that the present invention illustrates
It applies example and also introduces mounting plate component 45, be installed on vehicle frame 1, angular adjustment motor 411 and Level tune motor 430 are pacified
Loaded on mounting plate component 45, including corresponding feed screw nut component or rack and pinion assembly etc., also it is mountable to installation board group
On part 45.Further in alternative, mounting plate component 45 may include the first mounting plate and the second mounting plate, Level tune
Motor 430 is installed on the first mounting plate, and angle adjusting mechanism 41 is installed on the second mounting plate, and the driving of Level tune motor 430 is slided
When block structure 431 moves horizontally, synchronous driving angle regulation motor 411 is done to be moved horizontally accordingly, to ensure to adjust in angle
When motor 430 does not work, angle adjusts motor 411, connecting rod 412 and the connecting shaft being connected thereto, the second pushing block, leading screw spiral shell
Female component does synchronous movement.
The related vertical adjustment mechanism 42, the vertical adjustment mechanism 42 include set screw 420, the flaw detection wheel 30
Vertical position adjust and realized by being pre-adjusted for the set screw 420.Specifically, vertical adjustment mechanism 42 is also wrapped
The second plate 421 and third plate 422 are included, the first plate 414, the second plate 421 and can be adjusted by set screw 420
Position relationship between three plates 422, to realize that vertical adjustment, flaw detection wheel 30 and its mounting assembly are installed on third plate
On 422, certainly, set screw 420 also can further adjust mounting assembly etc. of flaw detection wheel relative to the second plate 421 and the
Position between three plates 422, as long as the adjustment between realizing plate, in other words eventually by the rotation of set screw 420
The vertical position for realizing flaw detection wheel 30 is adjusted, and is exactly optional scheme of the invention.
It can be seen that centering subsystem can guarantee the adjusting control of the flaw detection wheel 30 of ultrasonic wave, make flaw detection wheel 30 independently of directive wheel
61 move left and right axially, swing radially relative to rail rail level；It is hung down by being pre-adjusted set screw 420 and realizing
To adjusting, so that the flaw detection of ultrasonic wave is taken turns 30 pairs of rail surfaces certain pressing force, it is ensured that ultrasonic wave visits wheel and rail surface pair
In with couple it is good.
By illustrating in detail above, the concrete structure how realized in centering subsystem 4 of the present invention is illustrated, but
The realization method of the design of the present invention, three kinds of movements is not limited to this, above only to some preferred or alternatives of the present invention
One kind enumerate.
In the embodiment that the present invention illustrates, the subway double track rail-defect detector car further includes guide frame 6, described to lead
Include being installed on the directive wheel 61 and guide ploughing 62 of the vehicle frame 1 to structure 6, certainly, this installation can indirectly can also
It is direct.Derailing can occur in turnout passing idle space and slide down for guide ploughing, to ensure the normal of vehicle
It advances and flaw detection demand, 61 inner flange face moment of directive wheel is close to the working face of track, ensure that ultrasonic wave spy wheel being capable of the moment
It is run on the center line of rail.So in alternative of the present invention, the directive wheel 61 and guide ploughing 62 pass through spring 63
It is bonded Rail Surface.Certainly this fitting is not limited only to the effect of spring 63, further includes the effect of vertical adjustment mechanism 42 to realize.
The related flaw detection subsystem 3 please refers to Fig.1 1, and flaw detection subsystem adopts signal using high speed acquisition equipment
