Description
Technical Field
The invention relates to the field of safety protection of wharf engineering, in particular to an anti-collision device suitable for wharf.
Background
The wharf is a building for loading and unloading passengers and cargoes by berthing ships or ferries on seaside and river side. During berthing, the ship inevitably collides with the wharf to shake the ship body, which may damage the cargo on the ship or form potential safety hazards to passengers (especially old people and infants with inconvenient movements). Current partially older wharfs typically employ a row of scrap tires suspended from the contact surface of the wharf as a crude buffer. However, passengers still can be injured by shaking or even falling to the ground to a large extent, and the effect of buffering and anti-collision is poor. In addition, because of the existence of the junked tires, a gap with a foot width is formed between the ship body and the wharf, the circular outline of the junked tires is very wet and slippery after being wetted by sea (river) waves, and if passengers are not careful, personal safety accidents are easy to occur, and the consequences are serious.

Further, the H-shaped steel flange plates are placed in parallel with the wharf to resist bending moments generated when the ship hits the wharf.
Further, the number of the junked tires is determined according to the specific conditions of engineering, and each row can be kept consistent or sequentially reduced from the middle to the two ends.
Further, the diameter of the junked tire is between 60cm and 80cm, and the junked tire is selected according to engineering specific conditions.
Further, the number of turns and the width of the polyurethane foam and the natural rubber are dependent on the size of the scrap tire.
Further, the cantilever type pedal is made of galvanized pattern steel plates, and the outer extending section is wrapped by natural rubber with a certain thickness.
Further, an anti-corrosion layer is smeared on the surface of the H-shaped steel so as to effectively prevent the corrosion of the water body.
Further, the cantilever type sidewalk pedal is opposite to the entrance and exit of the passenger ship, two ends of the cantilever type sidewalk pedal are reserved for half a meter, the size and the connection mode of the bottom plate are the same as those of the cantilever type sidewalk pedal, and the anti-corrosion layers are coated on the cantilever type sidewalk pedal, so that the corrosion effect of the water body is effectively prevented.
