Abstract
The utility model discloses a destructive energy absorption spring, including the spring, the spring is pitch truncated cone coil spring such as central symmetry broad in the middle small in ends, the left end of spring is equipped with left spring hole, the right -hand member of spring is equipped with right spring hole, the spring does not possess the reset function. Destructive energy absorption spring adopt symmetric design's truncated cone spring, the stability of multiplicable atress, the spring does not possess the reset function after through thermal treatment, can take place permanent deformation behind the atress to reach the mesh of damage.
Description
Technical field
The utility model is related to high-altitude working safety equipment technical field, specifically a kind of destructive energy absorption
Spring.
Background technology
At present, existing work high above the ground drop protection measure is mainly work high above the ground personnel are protected by single hanging point
Shield, and situation about being directed to when work high above the ground personnel contingency occurs falling from high altitude is then not provided with corresponding safety prevention measure.Through right
Prior art is looked into newly, does not find have and the same or similar document report of this theme in high-altitude working safety equipment technical field.
Utility model content
The utility model provides a kind of destructive energy absorption spring.
The purpose of this utility model is that the work high above the ground drop protection measure solved on existing market mainly passes through single extension
Point is protected to work high above the ground personnel, and situation about being directed to when work high above the ground personnel contingency occurs falling from high altitude is then not provided with phase
The problem of the safety prevention measure answered.
The utility model solves the technical scheme that its technical problem used：A kind of destructive energy absorption spring, including
Spring, the spring is Central Symmetry equal pitch conical spring broad in the middle small in ends, and the left end of the spring is provided with a left side
Spring eye, the right-hand member of the spring is provided with right spring eye, and the spring does not possess reset function.
Further, the number of turns of the spring is 20 circles.
Further, the pitch of the spring is 10 millimeters.
Further, the vertebra angle of the spring is 13.35 degree, and the lead angle of the spring is 3.82 degree.
The beneficial effects of the utility model are：Destructive energy absorption spring described in the utility model is using symmetric design
Conical coil spring, can increase the stability of stress, and spring can occur forever by not possessing reset function after heat treatment after stress
Deformation long, so as to reach the purpose of damage.Destructive energy absorption spring described in the utility model can be used to be arranged on safety line
In energy snubber seat, safety line energy snubber seat is connected with safety line, the destructive characteristics when work high above the ground personnel fall
Amount absorbs spring and absorbs the energy produced when personnel fall, and stress is damaged, the impact coefficient when personnel of reducing fall.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Specific embodiment
The utility model is further illustrated with reference to the accompanying drawings and examples：
As shown in the figure, there is provided the embodiment of the utility model destructiveness energy absorption spring, including spring 1, the spring 1
It is Central Symmetry equal pitch conical spring broad in the middle small in ends, force stability can be increased, the left end of the spring 1 sets
The right-hand member for having left spring hole 2, the spring 1 is provided with right spring eye 3, and the spring 1 does not possess reset function after being heat-treated,
Can be permanently deformed after stress, so as to reach the purpose of damage.
The number of turns of the spring 1 is 20 circles.
The pitch of the spring 1 is 10 millimeters.
The vertebra angle of the spring 1 is 13.35 degree, and the lead angle of the spring 1 is 3.82 degree.
Destructive energy absorption spring described in the utility model can increase the steady of stress using the conical coil spring of symmetric design
Qualitative, spring can be permanently deformed, so as to reach the mesh of damage by not possessing reset function after heat treatment after stress
's.Destructive energy absorption spring described in the utility model can be used to be arranged in safety line energy snubber seat, safe heat input
Buffing pad is connected with safety line, and when work high above the ground personnel fall, destructive energy absorption spring absorbs when personnel fall and produces
Raw energy, stress is damaged, the impact coefficient when personnel of reducing fall.
