Description

A collision protection ring and collision protection structure Technical Field

[0001] This utility model relates to the field of energy-absorbing element technology, and more specifically to an anti-collision ring and anti-collision structure. Background Technology

[0002] Taking collision protection measures for bridges is particularly necessary. The purpose of these measures is to prevent the bridge from being structurally damaged by the impact of ships, while protecting ships as much as possible and minimizing the damage.

[0003] Currently, although the steel wire rope anti-collision ring, which is the mainstream flexible anti-collision component, has significant effects, it still has shortcomings. Specifically, the steel wire rope anti-collision ring consumes a large amount of steel, the steel wire rope needs to be tied with additional steel wires for fixation, the production and installation are complicated, and the process is unstable.

[0004] Therefore, how to provide a flexible anti-collision component with high resilience is a problem that urgently needs to be solved by those skilled in the art. Summary of the Invention

[0005] In view of this, the present invention provides a crash ring and crash structure, which reduces the amount of steel used in the crash ring by combining springs and rubber, while ensuring the crash ring's resilience and load-bearing capacity. To achieve the above objectives, the present invention adopts the following technical solution:

[0006] On the one hand, this utility model provides a collision protection ring, comprising:

[0007] A spring coil and a rubber ring are provided. The spring coil is formed by connecting the ends of an irregularly shaped spring. Rubber is provided on both the inside and outside of the irregularly shaped spring. The rubber inside and outside of the irregularly shaped spring are connected together to form a rubber ring.

[0008] Furthermore, the material of the rubber ring is neoprene rubber.

[0009] Furthermore, the spring coil is made of 65Mn spring steel.

[0010] Furthermore, the elastic coefficient of the irregularly shaped spring varies at different positions.

[0011] On the other hand, this utility model provides an anti-collision structure, including the aforementioned anti-collision ring, and also includes mounting components. Two mounting components are provided, and the two mounting components are located on the same central axis of the rubber ring. Each mounting component is provided with a mounting groove, and the rubber ring is disposed in the mounting groove. The anti-collision ring is fixedly installed through the mounting components.

[0012] Furthermore, the elastic coefficient of the irregular spring at the end near the mounting groove is smaller than the elastic coefficient at other positions of the irregular spring.

[0013] Furthermore, connecting plates are provided at both ends of the mounting groove, and connecting holes are provided on the connecting plates.

[0014] As can be seen from the above technical solution, compared with the prior art, the present invention discloses a crash ring with an irregularly shaped spring inside the rubber ring, which reduces the amount of steel used in the crash ring, improves economic efficiency, and at the same time improves the rebound performance and load-bearing capacity of the crash ring.

[0023] 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.

[0024] Referring to Figures 1-6, one embodiment of this utility model discloses a collision protection ring, comprising:

[0025] The spring ring and the rubber ring 22 are formed by connecting the ends of a section of irregular spring 21. Rubber is provided inside and outside the irregular spring 21. The rubber inside and outside the irregular spring 21 are connected together to form the rubber ring 22.

[0026] By placing the spring ring inside the rubber ring 22, the amount of steel used is reduced, and the economic efficiency is improved. At the same time, during the production process, the spring ring and rubber are placed directly in the mold, and the anti-collision ring 2 can be made without binding.

[0027] In some embodiments, the rubber ring 22 is made of neoprene rubber.

[0028] In some embodiments, the spring ring is made of 65Mn spring steel.

[0029] In some embodiments, the elastic coefficient of the irregular spring 21 is different at different positions.

[0030] On the other hand, this utility model embodiment discloses an anti-collision structure, including the aforementioned anti-collision ring 2, and also includes a mounting component 1. There are two mounting components 1, which are located on the same central axis of the rubber ring 22. The mounting component 1 is provided with a mounting groove 11, and the rubber ring 22 is disposed in the mounting groove 11. The anti-collision ring 2 is fixedly installed through the mounting component 1.

[0031] During the use of the anti-collision ring 2, the rubber rings 22 at both ends of the same central axis are placed into the mounting grooves 11 of the two mounting parts 1. The two mounting parts 1 are connected to the inner ring and outer ring of the anti-collision device respectively, so that the anti-collision ring 2 is placed between the inner ring and outer ring of the anti-collision device. When the actual ship hits the outer ring of the anti-collision device, the anti-collision ring 2 buffers and absorbs the impact force of the actual ship on the outer ring of the anti-collision device, reducing the damage caused by the actual ship hitting the outer ring.

[0032] In some embodiments, the elastic coefficient of the irregular spring 21 at the end near the mounting groove 11 is smaller than the elastic coefficient at other positions of the irregular spring 21.

[0033] During the installation of the anti-collision ring 2, the part of the spring ring with the smaller elastic coefficient is placed into the installation groove 11, which improves the rebound effect and load-bearing capacity of the anti-collision ring 2 while reducing costs and improving economic efficiency.

[0034] In some embodiments, connecting plates 12 are provided at both ends of the mounting groove 11, and connecting holes are provided on the connecting plates 12.

[0035] During the installation of the anti-collision ring 2, the connecting plate 12 on one mounting part 1 is connected to the inner ring of the anti-collision device by bolts, and the connecting plate 12 on the other mounting part 1 is connected to the outer ring of the anti-collision device by bolts, ensuring that the anti-collision ring 2 is securely connected between the inner and outer rings of the anti-collision device.

[0036] In some embodiments, the structural parameters of the spring coil are respectively set as follows: wire diameter = 1mm, number of coils = 24, outer ring diameter = 40mm, and inner ring diameter = 24mm. The thickness of the rubber on the outer side of the spring coil is 2mm. The rubber formulation is as follows: 200g chloroprene rubber; 2g sodium stearate; 8g magnesium oxide; 10g zinc oxide; 2g antioxidant (TMQ); 2g accelerator (DM); 70g carbon black; the mixing temperature is set to 90℃.

[0037] During the preparation process, the refined rubber is placed into a vulcanization mold, and the vulcanization temperature is set to 150℃. Pure rubber rings are prepared through the mold. Spring rings and rubber are placed into the vulcanization mold to prepare anti-collision ring 2.

[0038] In some embodiments, a quasi-static uniaxial loading and unloading test is performed using an Instron miniature electronic universal testing machine, with the compression displacement being 80.7% of the inner diameter of the anti-collision ring.

[0039] Experiments show that when the displacement of the spring coil, the pure rubber coil, and the anti-collision ring 2 is all 19.360 mm, the maximum load of the spring coil is approximately 54.550 N, the maximum load of the pure rubber coil is approximately 169.683 N, and the maximum load of the anti-collision ring 2 is approximately 251.680 N. The area enclosed by the hysteresis curve represents the energy dissipation of the material. Using the horizontal axis as the reference, the energy dissipation of the spring coil is approximately 37.369 N·mm, the energy dissipation of the pure rubber coil is approximately 536.343 N·mm, and the energy dissipation of the anti-collision ring 2 is approximately 726.044 N·mm. The data shows that the energy dissipation and load-bearing capacity of the spring anti-collision ring 2 are significantly greater than those of the pure rubber coil and the spring coil.

[0040] E = (Hh) / H × 100%

[0041] Where E represents the rebound rate, H represents the deformation height of the object after being subjected to external force, and h represents the height to which the object recovers after the external force stops. From the force-displacement test data obtained from the hysteresis curve, the rebound rate of the anti-collision ring 2 is 89.524%, indicating that the anti-collision ring 2 has high rebound performance, which helps the anti-collision device return to its original shape when subjected to external force.

[0042] Calculations show that the total volume of the anti-collision ring 2 is approximately 40856.412 mm. 3 The volume of the spring coil used is approximately 631.010 mm. 3 The volume of rubber ring 22 is approximately 40225.402 mm. 3 The ratio of the volume of steel used in the spring coil to the volume of rubber used in the rubber ring 22 is approximately 0.016.

Similar or identical parts between embodiments can be referred to interchangeably. For the apparatus disclosed in the embodiments, since they correspond to the methods disclosed in the embodiments, the description is relatively simple; relevant parts can be referred to the method section.
