Description

Technical Field

[0001] This utility model relates to the field of anti-collision barrel technology, specifically an anti-collision barrel with a rotating warning function. Background Technology

[0002] The construction and maintenance of roads and bridges are important aspects of highway traffic safety. Among them, road and bridge construction crash barriers are one of the key pieces of equipment to ensure the safety of pedestrians and vehicles. The crash barriers are made of highly elastic and high-strength modified plastics, which can effectively reduce the impact force when a car collides with the equipment. However, when a crash barrier is stationary, it rebounds linearly after a car collision, which can easily cause secondary injuries. A rotating crash barrier converts the linear impact force during a collision into rotational kinetic energy, reducing the risk of injury to occupants during a collision. If a crash barrier is slightly scratched by a collision, replacing the entire barrier is wasteful of materials, while not replacing it affects the aesthetics and the conversion of kinetic energy in the next collision, making it inconvenient to replace it quickly.

[0013] Specifically, the buffer cotton is distributed in a ring at equal intervals, and the two ends of the buffer cotton are respectively bonded and fixed to the inner cavity surface.

[0014] In this invention, the cushioning cotton is made of polyurethane composite material, which absorbs the remaining energy after the collision through deformation, and the anti-collision shell is made of low-density polyethylene, which increases elastic deformation and reduces the impact.

[0015] It is worth noting that the warning reflective stickers are distributed in a ring with equal spacing, and the inner side of each warning reflective sticker is bonded and fixed to the corresponding outer wall of the anti-collision shell. Furthermore, the total width of the warning reflective stickers is adapted to the distance between the two arc-shaped grooves.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figures 1-5 This embodiment provides a technical solution: A crash barrier with a rotating warning function includes two symmetrical crash barrier shells 2, with a positioning post 1 between the two crash barrier shells 2. The positioning post 1 is installed on a guardrail post and is ring-shaped. A circular ring 10 is provided on the outer wall of the positioning post 1 at a position corresponding to the slot 210. A groove 100 is provided on the outer wall of the circular ring 10, and a pulley 101 is provided in the groove 100.

[0023] In this utility model, with the cooperation of pulley 101, the flexibility of rotation of ring 10 and anti-collision shell 2 is increased. The groove 100 is distributed in a ring with equal spacing. The pulley 101 is embedded in the groove 100 and the outer ring of pulley 101 protrudes a part.

[0024] Furthermore, the pulley 101 is rotatably connected to the groove 100 via a rotating shaft, and the outer diameter of the circular ring formed by the pulley 101 is adapted to the inner diameter of the slot 210, with the outer wall of the pulley 101 closely fitting and close to the inner wall of the slot 210.

[0025] In this utility model, the pulley 101 fits into the slot 210, and the anti-collision shell 2 is snapped onto the pulley 101. The pulley 101 rotates flexibly, so that the anti-collision shell 2 can flexibly rotate and cooperate with the positioning post 1.

[0026] Specifically, several warning reflective stickers 3 are provided in the middle of the outer wall of the anti-collision shell 2; It should be noted that the inner cavity 20 is provided inside the anti-collision shell 2, and several buffer cotton 200 are provided in the inner cavity 20. The rotating groove 21 is provided in the middle of the opposite side of the anti-collision shell 2, and the slot 210 is symmetrically provided on the rotating groove 21. The positioning post 1 and the ring 10 are integrally formed, and the outer diameter of the positioning post 1 is adapted to the inner diameter of the rotating groove 21.

[0027] In this utility model, the positioning post 1 is rotatably connected to the rotating groove 21, and the ring 10 is rotatably connected to the slot 210. With the cooperation of the slot 210, the anti-collision shell 2 is positioned on the positioning post 1 to prevent it from sliding up or down and detaching from the positioning post 1.

[0028] Furthermore, the outer wall of the anti-collision shell 2 is symmetrically provided with arc-shaped grooves 22. One of the arc-shaped grooves 22 on the anti-collision shell 2 is provided with a retaining ring 220 near the port. The arc-shaped groove 22 on the other anti-collision shell 2 is provided with a buckle 23 corresponding to the retaining ring 220.

[0029] The outer walls of the retaining ring 220 and the buckle 23 are both inside the arc groove 22, which increases the overall aesthetics of the anti-collision shell 2 assembly.

[0030] It is worth adding that the retaining ring 220 and one of the anti-collision shells 2 are integrally formed, and the retaining ring 220 is provided with a through hole 221. The buckle 23 and the other anti-collision shell 2 are integrally formed. The buckle 23 is L-shaped, and the tip of the buckle 23 is a right-angled triangle. The buckle 23 passes through the through hole 221, and the corner engages with the through hole 221.

[0031] In this utility model, four buckles 23 are inserted and engaged with the corresponding through holes 221 on the retaining rings 220 to achieve the close-fitting and snap-fit ​​installation of the two anti-collision shells 2. The anti-collision shells 2 are wrapped around the outer wall of the positioning post 1. The four buckles 23 are separated from the through holes 221, which facilitates the disassembly and separation of the two anti-collision shells 2 for disassembly and replacement.

[0032] Secondly, the cushioning cotton 200 is distributed in a ring with equal spacing, and the two ends of the cushioning cotton 200 are respectively bonded and fixed to the inner cavity 20 surface.

[0033] In this invention, the cushioning cotton 200 is made of polyurethane composite material, which absorbs the remaining energy after the collision through deformation, and the anti-collision shell 2 is made of low-density polyethylene, which increases elastic deformation and reduces the impact.

[0034] In addition, the warning reflective stickers 3 are distributed in a ring with equal spacing. The inner side of each warning reflective sticker 3 is bonded and fixed to the outer wall of the corresponding anti-collision shell 2, and the total width of the warning reflective sticker 3 is adapted to the distance between the two arc-shaped grooves 22.

[0035] In this invention, the reflectivity is increased by the combination of multiple sets of warning reflective stickers 3, and the anti-collision shell 2 provides reflective warnings from multiple directions simultaneously when it rotates.

[0036] When using the anti-collision barrel with rotating warning function in this embodiment, firstly, the pulley 101 is installed in the groove 100 on the ring 10, and the ring 10 is fixed on the positioning post 1. The positioning post 1 is sleeved on the guardrail post where the warning anti-collision barrel needs to be installed. Then, multiple buffer cotton 200s are installed in the inner cavity 20 of the anti-collision shell 2, and multiple sets of warning reflective stickers 3 are respectively attached to the anti-collision shell 2. When assembly is required, the two anti-collision shells 2 are fitted close to the positioning post 1, and the positioning post 1 is engaged with the two rotating grooves 21. The ring 10 is inserted into the groove 210, and the outer wall of the pulley 101 is tightly fitted with the inner wall of the groove 210. Then, the buckle 23 is inserted into the corresponding through hole 221, and the triangular end of the buckle 23 is engaged with the retaining ring 220. When the car collides with the anti-collision shell 2, the linear impact force is converted into rotational kinetic energy. With the cooperation of the pulley 101, the two anti-collision shells 2 achieve rotational dispersion of the impact force, and the buffer cotton 200 absorbs part of the impact force to reduce collision damage. When the two anti-collision shells 2 are damaged by collision and need to be replaced, the buckle 23 is separated from the through hole 221, so that the two anti-collision shells 2 can be removed from the positioning post 1, avoiding material waste caused by replacing the whole shell.
