The horizontal center line of these parts overlaps, in the front cover upper cover plate 16 of bottom plate 9, and by screw 17 from the bottom of bottom plate 9
Portion is screwed into screw hole 14, and threaded function occurs between screw 17 and cover board 16, and cover board 16 is fixed on bottom plate 9, then by mine
Vehicle A is placed in the rear of the mine car B tailstock, enforces mine car A and mine car B, so that colliding between mine car A and mine car B, at this time
It is hit between first fixture block 2 and the second fixture block 3, the pressure of the first fixture block 2 acts between two the second fixture blocks 3, so that
Expansion, 4 forced compression of the first spring shorten two the second fixture blocks 3 between the second fixture block 3 and baffle 5 outward, then the first card
Block 2 sticks between two the second fixture blocks 3, and second spring 15 is compressed in the end of the first fixture block 2, so that second spring 15 shortens, this
When 4 stress of the first spring shorten and generate an opposition, act on two the second fixture blocks 3, so that two second
Fixture block 3 clamps the first fixture block 2, completes to fix, when entire mechanism is impacted at work, pressure acts on damping spring 11
On, so that damping spring 11 is compressed, damping spring 11 shortens, so that two pieces of limit plates 12 are in contact, are supported, slide at this time
Block 19 is buffered in 18 internal slide of sliding slot, while damping spring 11 generates an opposition, offsets partial pressure,
The stabilization between connecting plate 10 and the second fixed plate 13 is maintained, when needing to disengage in two mine cars, inwardly squeezes sliding pearl 7, it is sliding
Pearl 7 is moved inside guide rail 8, and applies pressure to crotch 6, so that crotch 6 inwardly collapses, while the second fixture block 3 is then to outreach
It opens, further compresses the first spring 4, a upward screen resilience can be generated since second spring 15 is in compressive state,
When distance separated between two the second fixture blocks 3 is greater than the width of the first fixture block 2, second spring 15 then pushes up the first fixture block 2
Out, it completes to split, completes the use process of entire mine car collision type connection and trip gear like this.
It although an embodiment of the present invention has been shown and described, for the ordinary skill in the art, can be with
A variety of variations, modification, replacement can be carried out to these embodiments without departing from the principles and spirit of the present invention by understanding
And modification, the scope of the present invention is defined by the appended.
