On 2A.In addition, the rear portion of directing plate 91 and the quilt cover 77 of limit switch 70 pass through from the outer side covers of vehicle-width direction, the cover 77
Bolt B 8 is fixed on framework 4A.
Next, the action of reference picture 10 and Figure 11 to obstacle deflector 1A illustrates.When rail truck derails, collision
Bar 10 and the rail collision for being omitted diagram.Thus, as shown in figure 11, rotation of the locking member 17 because of action component 2A upward
Turn power and be destroyed (fracture), so as to which action component 2A rotates upward.When action component 2A rotate upward predetermined angular with
When upper, the detection bar 71 of limit switch 70 is toppled over downwards by the action movie 92 of upside, so as to which limit switch 70 produces the
One signal.As a result, it is able to detect that derailing.
On the other hand, when barrier on the line be present, collision bar 10 and the barrier collision for being omitted diagram.By
This, as shown in Figure 10, action component 2A rearward rotates.If the impact between collision bar 10 is barrier more than setting
Hinder thing, then action component 2A rearward can rotate more than predetermined angular, the action that the detection bar 71 of limit switch 70 passes through downside
Piece 92 and topple over upward, so as to limit switch 70 produce secondary signal.As a result, as defined in being able to detect that more than weight
Barrier.But in the case where barrier gently will not extremely make action component 2A rotate to the degree of more than predetermined angular, should
Barrier is flown out by collision bar 10.
Moreover, in the present embodiment, because action component 2A can become by the elasticity of rubber bushing 61 and leaf spring 63
Shape rearward rotates, therefore even if applying revolving force to action component 2A carries out the detection of barrier, as long as from action component
2A cancels revolving force, and rubber bushing 61 and leaf spring 63 will return to original state, so that action component 2A is returned to just
Normal position.Therefore, obstacle deflector 1A can be reused after the detection of barrier.
(variation)
Above-mentioned second embodiment can also change as follows.
As the elastomer maintained action component 2A, 2B on normal position, can also without using rubber bushing 61 and
Using only leaf spring 63.In this case, in the same manner as the situation shown in Fig. 5, if make rotary shaft 5 be embedded in action component 2A,
In the centre bore of 2B pedestal 21.Or rubber bushing 61 can also be used only without using leaf spring 63.
In addition, it goes without saying that illustrated several modes (can also not have framework in the variation of first embodiment
4A, 4B, as signal generator 7 can use sensor etc. beyond limit switch 70) second can also be applied to implement
Mode.
