CN2182147Y - Power-absorbing bumper - Google Patents

Abstract

The utility model relates to a power absorbing bumper, which comprises a power absorbing element, a force transmission plate arranged on the periphery of the power absorbing element, and a fender waterproof structural layer. The power absorbing element is of a bundling of steel cable rings, and is formed by the bundling of a plurality of steel cable rings with adjacent diameters. The 90% to 95% of the power can be absorbed with 0.1 to 0.2 second when the moving body strikes the utility model. So the utility model can be arranged on the end of the refuge siding and the structures such as a water pole, a dock, a bank, etc. With the help of the utility model the collision damage by moving objects can be avoided, and the car or shape damage and the personal casualty can be avoided. The utility model is an ideal power absorbing bumper.

Description

Power-absorbing bumper

The utility model is a kind of energy-absorbing anti-collision device, can be used for building the usefulness that shaped traffic device such as protection vehicle, boats and ships, embankment, bridge post, harbour are made safety facilities.

The train refuge siding, large-scale structures such as pile and embankment in the water when being subjected to the accident collision of mobiles such as vehicle, boats and ships, can cause not only that car is ruined, ship is heavy, the people dies, and often also can make structures cause permanent damage.Loss when meeting accident collision in order to reduce, people often are equipped with anti-collision facility on structures, if any select spring for use, rubber makes damping body and makes fender, the foamed plastic of selecting for use that has makes collision mat as anti-collision body or the like ... but these anti-collision bodies energy-absorbing effect in its elastic range is little, so after being subjected to the mobile collision, often not enough because of energy-absorbing, facility is damaged, even cause casualties, therefore, employed anti-collision body is not ideal enough at present.

The purpose of this utility model just is to overcome the shortcoming of prior art, provides a kind of plastoelastic deformation merit that the kinetic energy of mobile can be become crashproof element to absorb the energy-absorbing anti-collision device that becomes heat energy afterwards.

The purpose of this utility model is achieved in that and comprises and it is characterized in that power-absorbing: power-absorbing is a steel wire rope loop, and fake is provided with force transmitting board outward, and force transmitting board is provided with the waterproof construction layer outward.

Because power-absorbing of the present utility model is a kind of steel wire rope loop, after it is subjected to the mobile bump, enter the plastoelastic deformation stage, a large amount of kinetic energy become the plastoelastic deformation merit of steel wire bending, and become energy in the mutual friction between steel wire and distribute.Therefore, energy-absorbing effect of the present utility model is very good, can prevent structures effectively by damage, avoids car and boat breaking-up, personal casualty, reaches the purpose of energy-absorbing anti-collision.

Below in conjunction with accompanying drawing, further set forth concrete enforcement of the present utility model.

Fig. 1 is a kind of structural representation of the present utility model.

Work of deformation scheme drawing when Fig. 2 is the utility model pressurized.

Referring to Fig. 1, the utility model comprises power-absorbing (2) and is located at its peripheral force transmitting board (4) and goes along with sb. to guard him waterproof construction layer (5).Power-absorbing (2) is a kind of bead coil, and it is to connect the steel rope two ends by rustproof aluminum alloy cover (1) to form; Rustproof aluminum alloy overlaps available LF21, AlMg1.8 or materials such as 5050 are made, in order to increase the energy-absorbing scope, power-absorbing (2) can form the boundling fake with boundling band (3) boundling by the adjacent steel wire rope loop of a plurality of diameters, the cross section of boundling fake is compact arranged accumulation triangle (as showing of B-B section drawing among Fig. 1), the boundling fake can be arranged boundling by 2 layers of 3 fakes and form, also can form with 3 layers of arrangement boundling and arrange boundlings with 4 layers and form by 6 fakes by 10 fakes, the rest may be inferred, on demand boundling.

The principle of energy-absorbing anti-collision of the present utility model is roughly as follows: after bumping against the energy-absorbing anti-collision device that is located on the structures (as train refuge siding termination, water king-pile, embankment etc.) when mobile.Steel wire rope loop enters elastic-plastic phase, and a large amount of kinetic energy becomes the plastoelastic deformation merit of steel wire bending, and simultaneously friction generates heat mutually between the steel wire, distributes, and through experimental test, in 0.1～0.2 second behind bump, energy absorbing reaches 90～95%.Fig. 2 illustrate the utility model be impacted the back work of deformation, its ordinate is stressed (F), horizontal seat is shown deformation displacement (d), dotted line represents to observe Hooke's law, solid line is an actual measurement profile, as can be seen from Figure 2, the steel rope energy-absorbing is not the area below the straight line of spring energy-absorbing, but the area under a curve of an approximate Double curve, when distortion increases, curve rises with nearly cube curve, therefore, and by element of the present utility model is demarcated, determine its elastoplasticity energy-absorbing scope, just configurable corresponding number makes its lotus (kinetic energy) scope of cutting that meets anticollision device, to satisfy the needs of different occasions.
