Description

Technical Field

[0001] This utility model belongs to the technical field of ramp anti-slip structure, specifically relating to an anti-slip layer structure for a roll-on / roll-off ship ramp. Background Technology

[0002] The anti-skid design of roll-on / roll-off (Ro-Ro) ship ramps provides sufficient friction for vehicles and cargo during loading and unloading, playing a crucial role in maintaining ramp safety and preventing accidents. The anti-skid layer material, a key component for achieving this function, is a composite material composed of resin binder and anti-skid abrasive. The strong adhesive properties of the resin and the high frictional properties of the anti-skid abrasive combine to form a surface coating with high anti-skid performance. However, in recent years, incidents of abrasive particles detaching and damaging the paint have become frequent. After prolonged use, re-application of anti-skid abrasive is necessary, which is cumbersome and increases costs. Furthermore, in rainy weather, if the amount of anti-skid abrasive is insufficient, rainwater adhering to the ramp and not drained promptly can affect the friction between the tires and the ramp surface, causing vehicles to slip and posing a safety hazard. Utility Model Content

[0003] In view of this, the purpose of this utility model is to provide a roll-on / roll-off ship ramp anti-slip layer structure to solve the problems of safety hazards and unstable anti-slip effect of the current roll-on / roll-off ship ramp anti-slip structure in rainy weather.

[0004] To achieve the above objectives, this utility model provides the following technical solution:

[0005] A roll-on / roll-off (Ro-Ro) ship ramp anti-slip layer structure includes a Ro-Ro ship and a ramp set at the stern of the Ro-Ro ship. The upper surface of the ramp is provided with an anti-slip structure, which includes strip-shaped flow guide grooves arranged along the length direction of the ramp, and the axis of the flow guide grooves along the length direction is on the same straight line as the axis of the ramp along the length direction. The upper surface of the ramp is provided with multiple flow intercepting grooves, and all flow intercepting grooves are mirror images of the axis of the flow guide grooves along the length direction. The end of each flow intercepting groove near the flow guide groove is gradually inclined downward on the horizontal plane and connected to it. The upper surface of the ramp is also fixed with multiple anti-slip protrusions, and the anti-slip protrusions are respectively set on both sides of the width direction of the flow guide grooves.

[0006] Furthermore, the ends of the intercepting channels near the width edge of the scaffolding are all gradually inclined downward on the horizontal plane, and multiple guide holes corresponding to the adjacent intercepting channels are opened on both sides of the scaffolding in the width direction. The number and position of each guide hole correspond to the adjacent guide channel, and the guide holes and guide channels are interconnected.

[0007] Furthermore, the anti-slip structure also includes multiple anti-slip strips disposed on the upper surface of the skid, each of which corresponds to a flow interception groove and is disposed along the edge of the flow interception groove on its lower end surface.

[0008] Furthermore, each of the anti-slip protrusions is cylindrical and vertically fixed to the upper surface of the skid, and each anti-slip protrusion has a circular groove coaxial with it on its surface.

[0009] Furthermore, the anti-slip structure also includes, from bottom to top, a steel plate base, an anti-corrosion layer, an anti-slip layer, a topcoat layer, and a wear-resistant layer arranged sequentially on the surface of the plank.

[0010] Furthermore, the anti-corrosion layer is an epoxy primer, the anti-slip layer is a high-toughness epoxy resin with anti-slip sand, the topcoat layer is a modified epoxy resin, and the wear-resistant layer is quartz sand. The high-toughness resin has a tensile strength ≥10MPa, an elongation at break ≥50%, and an adhesion strength to the substrate ≥10MPa, with a dosage of 1.5~2.5kg / m². 2 Anti-slip sand should be made of 3-5mm basalt or corundum, with a crushing value ≤10%, Los Angeles abrasion ≤20%, and a polishing value ≥50. The dosage should be 5-13 kg / m². 2 The modified epoxy resin has a tensile strength ≥8MPa, an elongation at break ≥60%, and a dosage of 0.5~2.0kg / m². 2 , the quartz sand particle size is 20 mesh to 40 mesh.

[0011] Furthermore, the upper surface of the guide channel is provided with a strip-shaped baffle, and the surface of the baffle is provided with multiple through holes.

[0012] The beneficial effects of this utility model are as follows:

[0013] This invention effectively concentrates some rainwater on the surface of the ramp into the guide channel by setting intercepting grooves and guiding grooves on the surface of the ramp, and then discharges the rainwater outside the ramp through the guide channel. Furthermore, the combination of intercepting grooves and guiding holes can also guide some rainwater out of the ramp surface, effectively reducing the accumulation of rainwater on the ramp surface. In addition, installing multiple anti-slip protrusions on the ramp surface can effectively increase the friction between the wheels and the ramp, effectively preventing slippage.

[0014] Other advantages, objectives, and features of this invention will be set forth in the following description and will be apparent to those skilled in the art to some extent, or may be learned by practice of this invention. The objectives and other advantages of this invention can be realized and obtained through the following description. Attached Figure Description

[0022] like Figures 1-4 As shown,

[0023] A roll-on / roll-off (Ro-Ro) ship ramp anti-slip layer structure includes a Ro-Ro ship and a ramp 1 located at the stern of the Ro-Ro ship. The upper surface of the ramp 1 is provided with an anti-slip structure, which includes strip-shaped guide grooves 2 arranged along the length direction of the ramp 1, with the axis of the guide grooves 2 along the length direction being on the same straight line as the axis of the ramp 1 along the length direction. The upper surface of the ramp 1 is provided with multiple intercepting grooves 3, and all intercepting grooves 3 are mirror images of the axis of the guide grooves 2 along the length direction. Any two intercepting grooves 3 arranged along the length direction of the guide grooves 2 are evenly spaced. The end of each intercepting groove 3 near the guide groove 2 is gradually inclined downward on the horizontal plane and connected to it. The upper surface of the ramp 1 is also welded with multiple anti-slip protrusions 4, and the anti-slip protrusions 4 are respectively located on both sides of the guide groove 2 in the width direction.

[0024] As shown in the diagram, due to the height difference between the roll-on / roll-off ship and the dock, the ramp 1 gradually slopes upwards from the dock to the roll-on / roll-off ship. When a car drives from the dock onto the roll-on / roll-off ship, multiple anti-slip bumps 4 effectively increase the friction between the car tires and the ramp 1, preventing the car from slipping uphill. Furthermore, when working in rainy weather, rainwater flows along the inclined surface of the ramp 1 towards the dock, and the intercepting channel 3 guides the rainwater on the surface of the ramp 1 into the guiding channel 2, effectively preventing rainwater from accumulating on the surface of the ramp 1, reducing the probability of the car tires slipping uphill, and improving driving safety. Moreover, the guiding channel 2 is located in the middle of the ramp 1, and the intercepting channel 3 is located on both sides of the guiding channel 2. Multiple anti-slip bumps 4 are provided between adjacent intercepting channels 3, conforming to the driving route of the car. The car wheels will not run over the guiding channel 2, ensuring the working efficiency of the guiding channel 2. The car tires can always be in contact with the anti-slip bumps 4, which also ensures the anti-slip function when driving in rainy weather.

[0025] In this embodiment, the end of the intercepting trough 3 near the width edge of the jump plate 1 is gradually inclined downward on the horizontal plane, and multiple guide holes 5 corresponding to the adjacent intercepting trough 3 are opened on both sides of the jump plate 1 in the width direction. The number and position of each guide hole 5 correspond one-to-one with the adjacent guide trough 2, and the guide hole 5 and the guide trough 2 are interconnected.

[0026] As shown in the figure, by opening guide holes 5 on both sides of the ramp 1 in the width direction, which are connected to the intercepting groove 3, they can cooperate with the guide groove 2 to further accelerate the discharge of rainwater from the surface of the ramp 1, prevent the accumulation of rainwater, and indirectly improve the safety of the vehicle when driving.

[0027] In this embodiment, the anti-slip structure also includes a plurality of anti-slip strips 6 welded and fixed to the upper surface of the springboard 1. Each anti-slip strip 6 corresponds one-to-one with the intercepting groove 3 and is disposed along the edge of the intercepting groove 3 on its lower end surface. The vertical cross section of each anti-slip strip 6 is trapezoidal.

[0028] Combination Figure 4 As shown, the anti-slip strip 6 is installed on one side of the intercepting groove 3. It can not only effectively prevent some rainwater from continuing to slide down the lower part of the ramp 1, allowing the rainwater to flow into the adjacent intercepting groove 3, but also increase the friction between the ramp 1 and the wheels, making up for the problem of insufficient friction in the area on the upper surface of the ramp 1 where the anti-slip protrusions 4 are not installed.

[0029] In this embodiment, each of the anti-slip protrusions 4 is cylindrical and vertically fixed to the upper surface of the springboard 1, and each anti-slip protrusion 4 has a circular groove 7 coaxial with it on its surface.

[0030] As shown in the figure, the anti-slip protrusion 4 has grooves 7 on its surface, which increases the resistance between the wheel and the road surface, further increasing the friction between the car tire and the anti-slip protrusion 4, and effectively preventing the car tire from slipping.

[0031] In this embodiment, the anti-slip structure further includes, from bottom to top, a steel plate base, an anti-corrosion layer, an anti-slip layer, a topcoat layer, and a wear-resistant layer disposed on the surface of the springboard 1;

[0032] The anti-corrosion layer is an epoxy primer, the anti-slip layer is a high-toughness epoxy resin with anti-slip sand, the topcoat layer is a modified epoxy resin, and the wear-resistant layer is quartz sand. The high-toughness resin has a tensile strength ≥10MPa, elongation at break ≥50%, bond strength to the substrate ≥10MPa, operating time at room temperature ≥20min, and open traffic time at room temperature ≤6h, with a dosage of 1.5~2.5kg / m2. The anti-slip sand is made of 3~5mm basalt or corundum, with a crushing value ≤10%, Los Angeles abrasion ≤20%, and a polishing value ≥50, with a dosage of 5~13kg / m2. The modified epoxy resin has a tensile strength ≥8MPa, elongation at break ≥60%, operating time at room temperature ≥20min, and open traffic time at room temperature ≤8h, with a dosage of 0.5~2.0kg / m2. The quartz sand has a particle size of 20 mesh~40 mesh.

[0033] In this embodiment, the upper surface of the guide channel 2 is provided with a strip-shaped baffle 8, and the surface of the baffle 8 is provided with multiple through holes, which can effectively prevent debris from falling into the guide channel 2.

[0034] Construction steps for anti-skid structure of ro-ro ship ramp:

[0035] (1) Use handheld compressed air sandblasting equipment to sandblast and remove rust from steel plates. The cleanliness should reach SA2.5 level. In areas that are difficult for equipment to reach, the cleanliness of manual small-scale grinding process should reach ST3 level. The anti-slip protrusions 4 are welded and fixed to the designated position on the surface of the scaffolding 1.

[0036] (2) To prevent localized oxidation, epoxy primer should be applied promptly after sandblasting and rust removal;

[0037] (3) Mix components A and B of the high-toughness resin evenly according to the specified ratio, immediately pour the mixed high-toughness resin onto the surface of the epoxy primer, and scrape it evenly with a scraper.

[0038] (4) Excessive manual application of anti-slip sand. The anti-slip sand should be applied with uniform thickness and fully cover the surface, without exposing the bottom layer.

[0039] (5) After the high-toughness resin has cured, clean the anti-slip sand. The cleaning must be thorough, and no residual or loose anti-slip sand, dust or harmful substances should be left. The cleaning should be carried out 2 to 3 times.

[0040] (6) After the anti-slip sand is cleaned, pour the topcoat components A and B into the bucket and stir evenly. Apply by spraying or rolling.

[0041] (7) Manually and evenly spread the quartz sand;

[0042] (8) During the maintenance period, pay attention to protective measures and strictly prohibit vehicles and traffic.

[0043] Finally, it should be noted that the above preferred embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although the utility model has been described in detail through the above preferred embodiments, those skilled in the art should understand that various changes can be made to it in form and detail without departing from the scope defined by the claims of this utility model.
