Referring to fig. 1 to 6, an embodiment of the present utility model provides a buffering and decelerating crash barrier, which includes a railing 100, a plurality of crash barrels 200 are disposed on the railing 100, the crash barrels 200 are used for bearing the impact from a vehicle, the crash barrels 200 include an energy release portion 201 and a buffering portion 202, the energy release portion 201 is used for releasing and releasing the impact capability of the vehicle, the buffering portion 202 directly bears the impact of the vehicle, and the buffering portion 202 includes a plurality of crash pieces 2021 detachably disposed on the energy release portion 201.

Specifically:

in this embodiment, referring to fig. 2 and 3, the anti-collision barrel 200 includes an energy release portion 201 located at the inner side and a buffer portion 202 located at the outer side, where the energy release portion 201 includes a sleeve 2011, an energy release member 2012 and a steel ring 2013, the sleeve 2011 is disposed in the steel ring 2013, the energy release member 2012 is disposed between the sleeve 2011 and the steel ring 2013, and because a gap exists between the sleeve 2011 and the steel ring 2013, the energy release member 2012 is disposed in the gap, so that when a vehicle is impacted, a contraction space can be reserved for the energy release member 2012 to release the impact caused by the vehicle, thereby achieving the purpose of buffering energy release.

In one embodiment, in order to ensure the energy release effect, as shown in fig. 2 and 6, the energy release members 2012 are arranged in a plurality along the longitudinal array, and each energy release member 2012 includes two symmetrically arranged conical springs 300, the first ends 301 of the conical springs 300 are welded to the sleeve 2011, and the second ends 302 of the conical springs 300 are welded in the steel ring 2013, so that when the anti-collision barrel 200 is impacted by a vehicle, the energy of one impact point is commonly absorbed by the conical springs 300 in the anti-collision barrel 200, unlike other anti-collision guardrails, when the anti-collision barrel 200 is impacted, the energy is released only by bearing the impact by the springs at the impact point.

In an embodiment, in order to realize the replacement of the anti-collision sheet 2021, as described with reference to fig. 4 and 5, the upper end and the lower end of the anti-collision sheet 2021 are integrally formed with L-shaped buckles 2022, the anti-collision sheet 2021 is buckled with the steel ring 2013 through the L-shaped buckles 2022, and of course, in order to firmly fix the anti-collision sheet 2021 and the steel ring 2013, the ends of the anti-collision sheet 2021 and the steel ring 2013 are buckled through the L-shaped buckles 2022 and then are reinforced by screws. It is conceivable that when the anti-collision barrel 200 is lightly impacted, the impact side of the anti-collision barrel 200 is lightly damaged, and other anti-collision sheets 2021 are intact, at this time, if the inner steel ring 2013 and other structures are not damaged, the anti-collision sheet 2021 with the lightly damaged impact side can be replaced, other undamaged anti-collision sheets 2021 are reserved, if the structures such as the inner steel ring 2013 also need to be replaced, at this time, the undamaged anti-collision sheet 2021 can be removed for reuse, resources are saved, resource waste caused by replacing the whole anti-collision barrel 200 at one time is avoided, and maintenance cost is effectively saved.

In one embodiment, in order to effectively mount the anti-collision barrel 200 to the balustrade 100, referring to fig. 1, the balustrade 100 includes an upper beam 101, a lower beam 102 and a column 103, wherein the upper beam 101 and the lower beam 102 are disposed at upper and lower ends of the anti-collision barrel 200, the column 103 penetrates the upper beam 101 and the lower beam 102, a sleeve 2011 is sleeved on the column 103, and the upper beam 101, the lower beam 102 and the column 103 are fixed by screws, so that the anti-collision barrel 200 is limited between the upper beam 101 and the lower beam 102. Thus, it is conceivable that a plurality of anti-collision barrels 200 are fixed to the balustrade 100, when a vehicle collides with the anti-collision barrels 200, due to the self structure of the conical spring 300, the anti-collision barrels 200 are collided, and torsion is generated to a certain extent when the conical spring 300 contracts, so that the collision direction of the vehicle is changed, the vehicle has a trend of sliding along the anti-collision barrels 200, friction is generated between the anti-collision barrels 200 and the side surface of the vehicle, the anti-collision barrels 200 are stopped after being twisted to a certain extent, and under the combined action of the anti-collision barrels 200, the vehicle is prompted to decelerate and finally stop, thereby preventing the vehicle from sliding out of control along the anti-collision barrels to a certain extent, and secondary accidents occur.

In one embodiment, the anti-collision barrel 200 is coated with color and provided with reflective markers, which can improve the recognition of roads and give more striking warning to drivers at night.

In summary, the buffer deceleration anti-collision protection provided by the embodiment of the utility model has the following advantages:

according to the buffer deceleration anti-collision protection provided by the embodiment of the utility model, the anti-collision barrel 200 is formed by the energy release part 201 and the buffer part 202, when the guardrail is impacted by a vehicle, the energy release part 201 can absorb impact energy to protect the safety of the vehicle, the vehicle is guided to turn to the right front direction by utilizing the anti-collision barrels 200, the vehicle is decelerated and finally stopped, the vehicle is prevented from being out of control and rushing out of the road surface, the probability of secondary accidents is reduced, and meanwhile, the buffer part 202 is assembled by the detachable anti-collision sheets 2021 and can be detached and replaced, so that the damaged anti-collision sheets 2021 can be replaced, other undamaged anti-collision sheets 2021 are reserved for further secondary use, resources are saved, and the resource waste caused by replacing the whole anti-collision barrel 200 is avoided.

The foregoing description of the preferred embodiments of the utility model is not intended to limit the utility model to the precise form disclosed, and any such modifications, equivalents, and alternatives falling within the spirit and scope of the utility model are intended to be included within the scope of the utility model.
