Specific manner of execution:
Pedestal 9 under upward impact loading, the single-ended way moving shock isolating apparatus of extension spring it is worked
Journey is divided into four-stage:Equipment 1 leaves equilbrium position and is moved downwardly to lower limit position, and equipment 1 returns to from lower limit position
Equilbrium position, equipment 1 move upward to upper extreme position from equilbrium position, and equipment 1 returns to equilbrium position from upper extreme position.
First stage, equipment 1 leave equilbrium position and are moved downwardly to lower limit position:Pedestal 9 is by upward shock loading
When, equipment 1 moves downward because effect of inertia leaves equalization point opposite base 9, and equipment 1 pushes connecting plate 2 and connecting rod 3 is downward
Motion, four connecting rods 3 push push rod 4 simultaneously and moved downward, the slide opening 5-5 of the sliding surface bar A4-4 of push rod 4 along portable plate A5
Move downward, the slide opening A6-4 of the sliding surface bar B4-2 of push rod 4 along sleeve 6 is moved downward, the contact jaw of the push pedal 4 moved downward
The contact surface A8-1 that face A4-1 heads on portable plate B8 is moved downward, and portable plate B8 cross bar A8-2 pulls downward on extension spring 7
Suspension ring B7-3, because the suspension ring A7-1 being now in contact with portable plate A4 is fixed, so as to which extension spring 7 is elongated, until
The kinetic energy of equipment 1 all switchs to the elastic potential energy of extension spring 7, equipment to lower limit position.
Second stage, equipment 1 return to equilbrium position from lower limit position:Pedestal 9 is fixed, extensive in extension spring 7
Under multiple power effect, suspension ring B7-3 hauls portable plate B8 cross bar A8-2 upwards, the portable plate B8 sliding surface A6-2 along sleeve 6 to
Upper motion, moved upwards so as to which portable plate B8 contact surface A8-1 pushes the contact face A4-1 of push rod 4, push rod 4 is along sleeve 6
Slide opening A6-4 move up, push rod 4 heads on connecting rod 3 and drives connecting plate 2 to move upwards, is transported upwards so as to push equipment 1
Move until portable plate B8 is moved to equilbrium position.
Phase III, equipment 1 move upward to upper extreme position from equilbrium position:Due to self inertia act on, equipment 1 after
Continuous motion upwards, now equipment 1 hauls connecting plate 2, screw rod 3 and push rod 4 and moved upwards, due to portable plate A5 slide opening 5-5 chis
The contact surface 5-1 that the very little slide opening A6-4 less than sleeve 6, the contact face B4-3 of push rod 4 head on portable plate A4 causes portable plate A4
Moved upwards along the sliding surface B6-8 of sleeve 6, portable plate A4 cross bar 5-3 hauls the suspension ring A7-1 of extension spring 7 upwards, now
Portable plate B8 is fixed so that the stretcher strain of extension spring 7, until the kinetic energy that equipment 1 is moved upwards all switchs to stretch bullet
The elastic potential energy of spring 7, equipment 1 arrive upper extreme position.
Fourth stage, equipment return to equilbrium position from upper extreme position:Under the effect of the restoring force of extension spring 7, suspension ring A7-
1 hauls downwards portable plate A5 cross bar 5-3, and portable plate A5's moves downward along the sliding surface B6-8 of sleeve 6, so as to portable plate A5
Contact surface 5-1 push the contact face B4-3 of push rod 4 and move downward, slide opening A6-4 of the push rod 4 along sleeve 6 is moved downward,
Equipment 1 is hauled by connecting rod 3 and connecting plate 2 to move downward, until portable plate A5 contacts stopping with the contact surface B6-7 of sleeve 6
Motion, equipment 1 return to equilbrium position.
