Abstract
The utility model discloses an absorb high shock force's rotatory pulley, including columniform pulley main part, the middle part of pulley main part is provided with the shaft hole, the outer face of cylinder middle part of pulley main part is provided with an annular groove coaxial with the pulley main part, still is provided with two annular reflection of light warning strip in the pulley main part of annular groove both sides. The utility model discloses absorb high shock force's rotatory pulley, it is through setting up the annular groove in the pulley main part, and the annular groove has leaveed the space for the elastic deformation of rotatory staving for rotatory pulley receive vehicle impact in the twinkling of an eye can be quick absorption impact energy, when turning into rotational energy with impact energy, can also pass through a large amount of impact energy of elastic deformation absorbed energy, thus the better collision accident that lightens of ability, set up the manufacturing cost that the annular groove can also reduce rotatory pulley simultaneously.
Description
Technical field
This utility model is related to a kind of traffic protection equipment, more particularly to a kind of anticollision barrier.
Background technology
Existing rotary barrel anticollision barrier, which is made up of column and the rotary barrel being enclosed within column, using the rotation of rotary barrel
Turn performance, the impact force to guardrail can be decomposed the tangential direction of rotary barrel, can effectively reduce the impact force of vehicle and guardrail,
Mitigate vehicle accident consequence.
But existing rotary barrel anticollision barrier, its rotary drum are cylindrical-shaped structure, absorb the poor-performing of impulsive force,
After deformation, restorability is poor, the technical problem such as manufacturing cost is higher.
Utility model content
In view of this, the purpose of this utility model is to provide a kind of rotation drum for absorbing high impulsive contact force, existing to solve
There is the technologies such as absorption impulsive force poor-performing, recoverable force ability, manufacturing cost height in the rotary barrel of rotary barrel anticollision barrier
Problem.
This utility model absorbs the rotation drum of high impulsive contact force, including the drum main body of cylinder, the drum main body
Middle part is provided with axis hole, and an annular groove coaxial with drum main body is provided with the middle part of the external cylindrical surface of the drum main body,
Two annular reflection alarming bars are additionally provided with the drum main body of annular groove both sides.
Further, the axial cross section of the annular groove is arc, and the edge of annular groove is cylindrical with drum main body
Cylinder is in intersection round-corner transition.
Further, axial notch is additionally provided with the external cylindrical surface of the drum main body, the axial notch is circumferentially square
To being evenly arranged at least four.
The beneficial effects of the utility model：
This utility model absorbs the rotation drum of high impulsive contact force, and which passes through annular groove is arranged in drum main body, annular
Groove is that the elastic deformation for rotating staving leaves space so that rotation drum quickly can be inhaled in the moment by Vehicular impact
Impact energy is received, while impact energy is converted into rotation function, moreover it is possible to which absorbing by elastic deformation can a large amount of impact energy
Amount, so as to preferably mitigate collision accident；Arranging annular groove simultaneously can also reduce rotating the manufacturing cost of drum.
Description of the drawings
Fig. 1 is the dimensional structure diagram of the rotation drum that this utility model absorbs high impulsive contact force；
Fig. 2 is the another embodiment dimensional structure diagram of the rotation drum that this utility model absorbs high impulsive contact force；
Fig. 3 is the cross section structure diagram of the rotation drum that this utility model absorbs high impulsive contact force.
Specific embodiment
With reference to the accompanying drawings and examples this utility model is further described.
As illustrated, the present embodiment absorbs the rotation drum of high impulsive contact force, including the drum main body 1 of cylinder, the rolling
Bucket main body in the middle part of be provided with axis hole 2, be provided with the middle part of the external cylindrical surface of the drum main body one it is coaxial with drum main body
Annular groove 3, is additionally provided with two annular reflection alarming bars 4 in the drum main body of annular groove both sides.
The present embodiment absorbs the rotation drum of high impulsive contact force, and which passes through annular groove is arranged in drum main body, and annular is recessed
Groove is that the elastic deformation for rotating staving leaves space so that rotation drum quickly can be absorbed in the moment by Vehicular impact
Impact energy, while impact energy is converted into rotation function, moreover it is possible to which a large amount of impact energys of energy are absorbed by elastic deformation,
So as to preferably mitigate collision accident；Arranging annular groove simultaneously can also reduce rotating the manufacturing cost of drum.
The axial cross section of annular groove described in the present embodiment is arc, and the edge of annular groove is outer with drum main body
In intersection round-corner transition, round-corner transition causes rotation drum that crackle is less prone to when being impacted, and rotates the drum longevity on the face of cylinder
Life is longer.
Axial notch 5 is additionally provided with the external cylindrical surface of drum main body described in the present embodiment, the axial notch is along circle
Circumferential direction has been evenly arranged four, and in being embodied as, the quantity of axial notch can also be more than four certainly.Axial notch
Deformation space can be reserved for the deformation of rotation drum further so that the performance of rotation drum apparatus with shock absorbing is higher, can enter
One step mitigates car accident injury.
The present embodiment absorbs the rotation drum of high impulsive contact force, is additionally provided with helical form steel wire 6, spiral in its drum main body 1
Steel wire can improve ripple type rotation drum apparatus with shock absorbing and recover the ability of deformation, make rotation drum not fragile when clashing into
Rhegma is bad.
The present embodiment absorbs the rotation drum of high impulsive contact force, is further fixedly arranged on rustless steel bushing 7, is being hit in its axis hole
When hitting, drum main body quickly rotates, and axis hole face can be subject to very big frictional force, and rustless steel bushing anti-wear performance is good, is avoided that axle
Hole wear damage.
Finally illustrate, above example is only unrestricted to illustrate the technical solution of the utility model, although ginseng
This utility model is described in detail according to preferred embodiment, it will be understood by those within the art that, can be to this
The technical scheme of utility model is modified or equivalent, without deviating from the objective and model of technical solutions of the utility model
Enclose, which all should be covered in the middle of right of the present utility model.
