Abstract
The invention discloses a kind of destructive energy absorption spring, including spring, described spring is centrosymmetry equal pitch conical spring broad in the middle small in ends, and the left end of described spring is provided with left spring hole, the right-hand member of described spring is provided with right spring eye, and described spring does not possess reset function.Destructive energy absorption spring of the present invention uses the conical coil spring of symmetric design, can increase the stability of stress, and spring does not possess reset function by after heat treatment, permanent deformation can occur after stress, thus reach the purpose damaged.
Description
Technical field
The present invention relates to high-altitude working safety equipment technical field, specifically a kind of destructive energy absorption spring.
Technical background
At present, work high above the ground personnel are mainly protected by existing work high above the ground drop protection measure by single hanging point
Protect, for work high above the ground personnel just in case occurring situation during falling from high altitude to be then not provided with corresponding safety prevention measure.Through right
Prior art is looked into newly, does not finds have document same or similar with this theme to report in high-altitude working safety equipment technical field.
Summary of the invention
The invention provides a kind of destructive energy absorption spring.
The work high above the ground drop protection measure on existing market that present invention aim to address is mainly by single hanging point pair
Work high above the ground personnel protect, for work high above the ground personnel just in case occurring situation during falling from high altitude to be then not provided with accordingly
The problem of safety prevention measure.
The technical solution adopted for the present invention to solve the technical problems is: a kind of destructive energy absorption spring, including spring,
Described spring is centrosymmetry equal pitch conical spring broad in the middle small in ends, and the left end of described spring is provided with left spring
Hole, the right-hand member of described spring is provided with right spring eye, and described spring does not possess reset function.
Further, the number of turns of described spring is 20 circles.
Further, the pitch of described spring is 10 millimeters.
Further, the vertebra angle of described spring is 13.35 degree, and the lead angle of described spring is 3.82 degree.
The invention has the beneficial effects as follows: destructive energy absorption spring of the present invention uses the truncated cone bullet of symmetric design
Spring, can increase the stability of stress, and spring does not possess reset function by after heat treatment, can occur forever to become after stress
Shape, thus reach the purpose damaged.Destructive energy absorption spring of the present invention can be used for being arranged on safety line energy snubber
In Zuo, safety line energy snubber seat is connected with safety line, the destructiveness energy absorption spring when work high above the ground personnel fall
The energy produced when absorption personnel fall, stress damage, the impact coefficient when personnel of reducing fall.
Accompanying drawing explanation
Fig. 1 is the structural representation of the present invention.
Detailed description of the invention
The present invention is further described with embodiment below in conjunction with the accompanying drawings:
As shown in the figure, it is provided that the embodiment of destructiveness energy absorption spring of the present invention, including spring 1, described spring 1 is two
Holding little centrosymmetry equal pitch conical spring broad in the middle, can increase stability under loading, the left end of described spring 1 is provided with a left side
Spring eye 2, the right-hand member of described spring 1 is provided with right spring eye 3, and described spring 1 does not possess reset function by after heat treatment, is being subject to
Permanent deformation can occur after power, thus reach the purpose damaged.
The number of turns of described spring 1 is 20 circles.
The pitch of described spring 1 is 10 millimeters.
The vertebra angle of described spring 1 is 13.35 degree, and the lead angle of described spring 1 is 3.82 degree.
Destructive energy absorption spring of the present invention uses the conical coil spring of symmetric design, can increase stablizing of stress
Property, spring does not possess reset function by after heat treatment, and permanent deformation can occur after stress, thus reaches the mesh damaged
's.Destructive energy absorption spring of the present invention can be used for being arranged in safety line energy snubber seat, safety line energy snubber
Seat is connected with safety line, and when work high above the ground personnel fall, destructiveness energy absorption spring absorbs generation when personnel fall
Energy, stress damage, the impact coefficient when personnel of reducing fall.
