Kind be applied to double railway self-propelled walk the wheel seach unit frame of rail-defect detector car and CN206317819U is provided one kind is portable can
The rail examination vehicle carriage of dismounting, in wheel when passing through railway frog, from two wing rails it is most narrow to frog centre it is most advanced it
Between have one section of gap, here it is the idle spaces of track switch.
Ultrasonic probe needs have mechanical centering or automatic centering ability in operation, existing small applied to double track flaw detection
The probe holder of vehicle is substantially using mechanical centering mode, i.e., makes wheel edge using spring, cylinder etc. or be oriented to the structural members such as steamboat
Rail medial surface is withstood as benchmark.This machinery centering mode is relatively easy to realize, and reliable and stable, but simultaneously also to flaw detection
Some influences are brought by track switch in trolley operation process, when probe holder passes through gap in the frog, pressure can make to withstand rail
The structural member of medial surface is absorbed in the gap, as shown in Figure 1, causing trolley that can not pass through.Existing probe holder is using guiding plow structure
Solving the problems, such as this, it is desirable that the guide ploughing front and back end length L framves of existing wheel seach unit frame need to be longer than idle space distance L rails,
As shown in Fig. 2, however due to the magnitude relationship of its equipment, be unfavorable for fast quick-detach with it is portable.
Utility model content
The technical problem to be solved by the embodiment of the utility model is, providing one kind being applied to machinery from centering probe holder
Moving walks branch off mechanism.Track switch can be passed through under guide pad effect and can greatly reduce longitudinal ruler before and after wheel seach unit frame
It is very little.
In order to solve the above-mentioned technical problem, the utility model embodiment provides one kind applied to mechanical from centering probe holder
Moving walks trouble mechanism, including wheel seach unit frame, the wheel seach unit frame on front and back setting the structural member for being close to trackside, set
It is placed in the wedge-shaped guide pad of the structural member outer end, contact of the wedge shape guide pad inboard close to the structural member with rail
The width at end, the wedge shape guide pad is greater than or equal to the maximum shifting amount of the traversing part of wheel seach unit frame automatic centering.
Further, the maximum shifting amount of the wheel seach unit frame is greater than or equal to maximum standard gauge and installation is described wheeled
The rail-defect detector car travelling wheel inner surface sides of probe holder are apart from its difference.
Further, the wedge-shaped guide pad angle at the end is less than 45 degree.
Further, the wedge-shaped guide pad angle at the end is less than 30 degree.
Further, the structural member is rail row steamboat or rail row wheel edge.
Implement the utility model embodiment, has the advantages that：By the way that wedge-shaped guide pad is arranged, determine that wheel probe exists
Meet the traversing amount of required maximum in the case of automatic centering and limit, makes in guide pad inclined-plane outermost point remains in-orbit
Within side, wheel seach unit frame can not only be made to pass through track switch under the effect of wedge-shaped guide pad, wheel can also be greatly reduced
Longitudinal size before and after probe holder, facilitate its Quick Release with it is portable.

Specific implementation mode
It is new to this practicality below in conjunction with attached drawing to keep the purpose of this utility model, technical solution and advantage clearer
Type is described in further detail.
With reference to Fig. 3, structural schematic diagram shown in Fig. 4.
The a kind of of the utility model embodiment is applied to moving walks trouble mechanism of the machinery from centering probe holder, including wheeled
The structural member 2 for being close to trackside of front and back setting on probe holder 1, wheel seach unit frame 1 is set to wheel seach unit frame front and back end and sets
The wedge-shaped guide pad 3 set.
Structural member 2 is used to be adjacent to the inboard face of rail to be measured, and in the present embodiment, structural member is preferably oriented to steamboat, wedge
Shape guide pad 3 is inboard close to the contact jaw with rail for being oriented to steamboat, can theoretically be located at the tangential direction for being oriented to steamboat
On, and the position at preferably wedge-shaped 3 inboard end of guide pad can select its inboard end distance be oriented to steamboat tangential direction 1 ~
5mm, as shown in Figure 3.
The width D of wedge-shaped guide pad 3 is greater than or equal to the maximum shifting amount H of the traversing part of 1 automatic centering of wheel seach unit frame.
The maximum shifting amount H of the traversing part of 1 automatic centering of wheel seach unit frame is greater than or equal to maximum rail distance Smax and peace
Fill the difference of the rail-defect detector car travelling wheel inner surface sides distance Q of the wheel seach unit frame.
Wedge-shaped guide pad angle at the end is less than 45 degree, and preferred range is less than 30 degree.
The wedge-shaped preferred angle in guide pad end be 40 ± 3 degree, 35 ± 3 degree, 30 ± 3 degree, 25 ± 3 degree, 20 ± 3 degree, 15
± 3 degree, 10 ± 3 degree.
This is that another embodiment of the utility model is used to be adjacent to as shown in figure 5, structural member 2 is preferably rail row wheel edge
