The length of described electric threaded shaft is greater than the right girth of measured wheel.
The described electric threaded shaft outside is provided with semi-enclosed dust boot, and the opening part of described dust boot is positioned at the connecting portion of connecting arm and electric threaded shaft.
The present invention has the following advantages compared to existing technology:
The present invention detects the speed of wheel by the wheel velocity detector, and control the motor speed of electric driving mechanism by computing machine, carry out the mobile probe support, make detecting device can train by the time follow the right motion of measured wheel, be that the surface that linear transducer array on probe bracket and wheel velocity detector can be right with measured wheel keeps laminating and relative sliding, thereby realized the non-destructive test that measured wheel is right.
Detection setting of the present invention can according to circumstances arrange many groups and take turns carrying out comprehensive non-destructive test a plurality of simultaneously; And there is simple in structure, easy to operate, low cost of manufacture and easy care, there is larger economic benefit, suitable promoting the use of.
The accompanying drawing explanation
Accompanying drawing 1 is structural representation of the present invention.
Fig. 2 is pop one's head in array and the lateral plan of measured wheel to contacting of the present invention.
Wherein: 1-track; 2-probe bracket; 3-measured wheel pair; 4-linear transducer array; 5-wheel velocity detector; 6-connecting arm; 7-leading screw; 8-electrical motor; 9-signal processing controls computing machine; 10-buffering and driven structure; 11-dust boot.
The specific embodiment
Below in conjunction with accompanying drawing and embodiment, the present invention is further illustrated.
As shown in Figure 1: a kind of Mobile device for detecting wheel set of track trains, this detecting device comprises the probe bracket 2 that is arranged on track 1 outside, probe bracket 2 is arranged on measured wheel to 3 bottom or side and can moves 3 working direction along measured wheel, be provided with the linear transducer array 4 and the wheel velocity detector 5 that 3 bottom or contacts side surfaces are connected with measured wheel on probe bracket 2, wherein linear transducer array 4 is positioned at the upper end of probe bracket 2, linear transducer array 4 is comprised of ultrasonic probe or other photoelectricity classes probe, and linear transducer array 4 adopts the flexible structures such as spring or rubber when mounted, and in the lower end of probe bracket 2, be provided with the buffering and driven structure 10, to guarantee that detecting head surface in linear transducer array 4 and measured wheel have good contacting to 3 surface, in linear transducer array 4, a side or the both sides of linear transducer array 4 are provided with the wheel velocity detector 5 be arranged on probe bracket 2, wheel velocity detector 5 also can be arranged on the sidewall of probe bracket 2, and wheel velocity detector 5 is used for detecting measured wheel to 3 kinematic velocity.Probe bracket 2 passes through connecting arm 6 and is connected with electric driving mechanism, electric driving mechanism can adopt electric threaded shaft or electric pushrod, in the present embodiment, adopted the mode of electrical motor 8 and leading screw 7, wherein leading screw 7 be arranged in parallel with track 1, and leading screw 7 is connected with electrical motor 8, under the effect of electrical motor 8, leading screw 7 drives probe bracket 2 motions, makes linear transducer array 4 and wheel velocity detector 5 on probe bracket 2 to fit and relative sliding to 3 contact surface maintenance with measured wheel; In order to prevent that foul from can have influence on the normal operation of leading screw 7, be provided with semi-enclosed dust boot 11 in the outside of leading screw 7 in addition, the opening part of this dust boot 11 is positioned at the connecting portion of connecting arm 6 and leading screw 7, and the length of electric threaded shaft 7 is greater than measured wheel to 3 girth.Linear transducer array 4, wheel velocity detector 5 and electrical motor 8 are connected with signal processing controls computing machine 9 by circuit in addition.
