Description

An anti-collision device suitable for docks

technical field

The invention relates to the field of safety protection of wharf engineering, in particular to an anti-collision device suitable for a wharf.

Background technique

A wharf is a building on the seaside or river that is specially used for ships or ferries to berth, to allow passengers to get on and off, and to load and unload goods. During the docking process, the ship will inevitably collide with the pier and cause the hull to shake, which may cause damage to the cargo on board, or pose a safety hazard to passengers (especially the elderly and young children with limited mobility). At present, some old wharves usually use a row of waste tires suspended on the contact surface of the wharf as a simple buffer device. However, passengers will still be shaken significantly or even injured when they fall to the ground, which shows that the effect of cushioning and anti-collision is poor. In addition, due to the existence of waste tires, there is a foot-wide gap between the hull and the wharf. The circular outline of waste tires is very slippery after being wet by sea (river) waves. If passengers are not careful, personal safety accidents are prone to occur, with serious consequences.

Detailed ways

The present invention will be described in further detail below in conjunction with the accompanying drawings.

As shown in Figures 1 and 2, the present invention provides a kind of anti-collision device applicable to the wharf, the device includes a cantilevered pedestrian pedal 1, H-shaped steel 2, a buffer string 3 and a base plate 4; the cantilevered pedestrian pedal 1 is located at the top of the whole device, the transverse surface of the cantilevered pedestrian pedal 1 is L-shaped, the bent short side is fixed on the dock, and the long side is a cantilever structure, which is used as a passage for passengers to get on and off the ship; A number of vertical H-shaped steel 2 are welded, and the outer side of the H-shaped steel 2 is covered with buffer strings 3. The buffer strings 3 are not constrained, can freely rise and fall with changes in water level, and are close to the wharf to be protected, forming a retaining wall enclosure in space; the arm-type pedestrian pedal 1, H-shaped steel 2 and the bottom plate 4 jointly form the main frame of the anti-collision device; The main body, the 5 numbers of waste tires are determined depending on the specific conditions of the project, and each column can be kept consistent, or decreased from the middle to both ends. The distance between adjacent H-shaped steels 2 is greater than the diameter of the waste tire 5 , and the widths of the cantilevered pedestrian pedal 1 and the bottom plate 4 are both smaller than the diameter of the waste tire 5 . The material of the cantilevered pedestrian pedal 1 is galvanized checkered steel plate, and the overhanging section is wrapped with a certain thickness of natural rubber. The surface of the H-shaped steel 2 is coated with an anti-corrosion layer to effectively prevent the corrosion of water bodies.

As shown in Figure 3, the H-shaped steel 2 is welded on the H-shaped steel welding position 6 of the bottom plate 4, and the flange plate of the H-shaped steel 2 is placed in parallel with the wharf to resist the bending moment generated when the ship hits the wharf. The cantilevered pedestrian pedal 1 has a length of half a meter reserved at its two ends relative to the entrance and exit of the passenger ship. The size and connection method of the bottom plate 4 are the same as the cantilevered pedestrian pedal 1. They are all connected to the wharf by bolts 9, and are all coated with an anti-corrosion layer to effectively prevent the corrosion of the water body.

As shown in Figure 4, the lightweight flexible filler is composed of polyurethane foam 7 and natural rubber 8 that are alternately adhered to and surrounded from the inside to the outside, and the innermost layer is filled with polyurethane foam 7 to form a cylinder surrounding the H-shaped steel 2; after the natural rubber 8 is used to cling to the cylinder for one circle, the polyurethane foam 7 is closely adhered to it for another circle, alternately clinging and surrounding, the number of circles and width depends on the specific situation of the waste tire 3;

When the device works, the buffer string 3 will float to the touch position when the hull is docked with the fluctuation of the water level. The hull usually decelerates and approaches the device located on the shore before berthing. First, the waste tire 5 is used as the first barrier. After being squeezed and deformed by the collision, the impact force is continuously transmitted to the light flexible filler and the H-shaped steel 2 inside. The internal force is adjusted to the best stress state through the cantilevered pedestrian pedal 1 and the bottom plate 4. The three are jointly deformed by force, and part of the kinetic energy of the hull is quickly converted into the buffer string 3 and the deformation energy of the H-shaped steel 2 is stored, so that the speed of the hull is reduced. The effect greatly dissipates the impact force of the hull on the dock, and only a small part of the residual impact energy will be transmitted to the dock. From the durable material to the design concept of the triple barrier, the device ensures the safety and stability of the ship when it is docked at the dock. After the hull is completely docked, the entrance and exit are opened, and passengers can get on and off the ship through the cantilevered pedestrian pedal 1 of the device. The cantilevered pedestrian pedal 1 is specially made of patterned steel plates to increase the roughness and improve the comfort and safety of passengers when getting on and off the ship. The device can effectively protect the wharf building under the normal docking operation of the crew. The wear resistance and durability of the material are very good, which can ensure the normal operation of the device for a long time.
