Embodiment 1
As shown in Figs 1-4, the utility model provides a kind of urgent stopping device of hydraulic crawler excavator, including fuselage 1, fuselage 1
Bottom be provided with crawler belt 2, the side of fuselage 1 is provided with second mechanical arm 4, and the side of second mechanical arm 4 is provided with the first machine
Tool arm 3 is provided with connecting shaft 5 between first mechanical arm 3 and second mechanical arm 4, the outside of second mechanical arm 4 is provided with slide 6,
Connecting shaft 5 sequentially passes through first mechanical arm 3, second mechanical arm 4 and slide 6 from inside to outside, and extends to the outside of slide 6, the
The top of two mechanical arms 4 is provided with motor 7, and drive screw 15, the inside of second mechanical arm 4 are provided between motor 7 and slide 6
It is provided with fixing seat 8, the side of fixing seat 8 is provided with spring 9, and the side of spring 9 is provided with sliding block 10, sliding block 10 and connecting shaft
5 socket-connect, and opposite can slide between sliding block 10 and connecting shaft 5 but relatively unrotatable, the outside of sliding block 10 is provided with positioning seat
12, location hole 13 is provided on positioning seat 12, and positioning pin 14 is provided on sliding block 10.
Further, spring 9 and sliding block 10 are sequentially connected, and spring 9 is fixedly connected with fixing seat 8, and slide 6 is displaced outwardly
When, spring 9 extends, since spring 9 is fixedly connected with fixing seat 8, spring 9 makes to restore original appearance to both sides
Sliding block 10 is mobile, is inserted into the positioning pin 14 of sliding block 10 in the location hole 13 of positioning seat 12.
First mechanical arm 3 and connecting shaft 5 are sequentially connected, when hydraulic tube pulls first mechanical arm 3,3 turns of first mechanical arm
It is dynamic, while connecting shaft 5 being driven to rotate in second mechanical arm 4.
The bottom of first mechanical arm 3 is provided with scraper bowl 11, and excavator is allow to work.
Positioning seat 12 is fixedly connected with second mechanical arm 4, is fixed positioning seat 12.
Specifically, first mechanical arm 3 and connecting shaft 5 are sequentially connected in normal work, when hydraulic tube pulls the first machinery
When arm 3, first mechanical arm 3 is rotated, while connecting shaft 5 being driven to rotate in second mechanical arm 4, when needing stop, starting electricity
Machine 7, motor 7 drive drive screw 15 to rotate, and drive screw 15 and slide 6 form ball screw nut structure, drive screw 15
