Abstract

The utility model discloses a power absorber of a highway cable guardrail, consisting of a hollow outer tube, the two end covers having a through hole, a spring arranged in the outer tube and a cable of which the end is provided with a die fixedly; one end of the cable is fixed by the die after passing through the through hole and the spring; the connection between the die and the spring can be a welding way or a forcipression and so on; a circular washer is arranged between the die and the spring; a screw thread is arranged on an outer wall on the both ends of the outer tube and an inner wall of the end cover; the outer tube is cooperated with the end cover through a thread rotation. The utility model has a power absorbing function and the advantages of the convenient construction, the beautiful appearance, the easy maintenance and the simple structure, which fully utilizes an elastic force of the spring in the device to reduce an impact force of a vehicle to the guardrail and protect a personnel and the vehicle more effectively in a traffic accident and reduce a damage rate of the guardrail; for the non-broken pillar, only the spring and the washer of the pillar need to be changed; thereby the maintenance cost is saved greatly; and any striking mark does not exist after maintenance.

Description

Highway cable guardrail energy absorber

Technical field

The utility model relates to a kind of novel road cable guardrail safety device, particularly a kind of highway cable guardrail energy absorber.

Background technology

In recent years along with society, expanding economy, highway construction has also obtained swift and violent development, from original unshielded hurdle, the two-way bicycle road of isolated column two-way multilane till now with protective guard and isolated column, highway capacity strengthens greatly, the also corresponding raising of traffic safety, though extending the increase of establishing with the security protection facility, highway improved driving and safety condition greatly, but still the accident of not avoiding situations such as because of weather conditions abominable or overspeed violation travels to cause fully, accident has not only caused the loss of public property, the more important thing is also often to cause driver's injures and deaths.Existing protective guard and isolated column great majority constitute with pilum and the protected apron or the division board that are fixed on the pilum, such protective guard itself is to be made by harder metal material, belong to rigidity and semi-rigid material, there is not elasticity, really can play certain stopping and protective action to slow vehicle, but to the speed of a motor vehicle faster vehicle just can not play protection, barrier effect, can not play the effect of energy-absorbing and buffering effectively to the bump of vehicle, the protective guard that is clashed into when accident takes place simultaneously also can be badly damaged, it is very inconvenient that protective guard breaks the back maintenance, backplate needs to change again, and is time-consuming.

Summary of the invention

The purpose of this utility model is to disclose a kind of simple in structure, economy, safety, can reduce the highway cable guardrail energy absorber of impact force action.

For reaching the foregoing invention purpose, the technical scheme that is adopted is: a kind of highway cable guardrail energy absorber, by hollow urceolus, two have the end cap of through hole, the cable that places spring in the urceolus and end to be fixed with die connects and composes, cable one end pass be connected with die behind through hole and the spring on the end cap fastening, die can be by modes such as welding or pincers pressures with being connected of spring, between die and spring, be provided with the packing ring of annular, urceolus two ends outer wall and end cap inwall are provided with screw thread, and urceolus screws by screw thread with end cap and cooperates.

The internal diameter of described packing ring is less than the internal diameter of die and spring, and its external diameter is greater than the external diameter of spring.

During use, this device is passed through such as securing member horizontal fixed such as buckles on the other pilum of highway, every cables of every foundation post is fixed this device, connects by cable between the device on the different pilums.Can use protected apron, division board connect many parallel cables when increasing bump with the contact area of vehicle, reduce because of the meticulous situation generation excessive of cable the stress of vehicle part.

This highway cable guardrail energy absorber is a kind of novel road cable guardrail safety device; the cable guardrail is formed a kind of flexible highway protection guardrail jointly by galvanized steel wire rope and energy absorber; it is compared than traditional rigid protection guardrail not only has energy-absorbing function and also has easy construction; handsome in appearance; characteristics such as easy care; it is simple in structure; the elastic force that makes full use of the device medi-spring reduces the impact force of vehicle to protective guard; more effectively when accident takes place to personnel; the protection of vehicle; also reduced simultaneously the spoilage of protective guard; destroy the ground pilum fully to not taking place; the spring and the packing ring that only need to change pilum get final product; saved maintenance cost greatly, the maintenance back is without any striking mark.

The specific embodiment

Below in conjunction with accompanying drawing the utility model is described in further detail:

As shown in Figure 1, a kind of highway cable guardrail energy absorber, by hollow urceolus 1, two have the end cap 4 of through hole, the cable 5 that places spring 6 in the urceolus 1 and end to be fixed with die 3 connects and composes, through hole and spring 6 backs that cable 5 one ends pass on the end cap 4 are fastenedly connected with die 3, between die 3 and spring 6, be provided with the packing ring 2 of annular, urceolus 1 two ends outer wall and end cap 4 inwalls are provided with screw thread, and urceolus 1 and end cap 4 screw by screw thread and cooperate.The internal diameter of packing ring 2 is less than the internal diameter of die 3 and spring 6, and its external diameter is greater than the external diameter of spring 6.
