Bridge anti-collision structure with bridge pier protection function

Abstract

The invention discloses a bridge anti-collision structure with a bridge pier protection function, and relates to the technical field of bridge protection. The bridge anti-collision structure with thebridge pier protection function comprises an installation seat, a buffer box, a buffer frame, a support frame, six transmission rolls and a buffer belt, wherein the buffer frame is of a U-shaped platestructure; thirty-two slide columns are fixed to one surface of the buffer frame; thirty-two first springs are fixed between the buffer frame and one inner wall of the buffer box; and the first springs are arranged on the outer surfaces of the slide columns in a surrounding manner. According to the bridge anti-collision structure with the bridge pier protection function, the buffer belt is drivento transmit around the transmission roll to relieve a force through friction between a filling bag and a ship, first-time buffer is carried out through co-use for a filler in the filling bag and gasin the filling bag, second-time buffer is carried out through an elastic force and a pull force which are provided by second springs, third-time buffer is carried out through that the first springs are extruded to generate an elastic force, and fourth-time buffer is carried out through co-use for a rubber plate and a closed-pore foamed aluminum plate, so that the problem of poor protection effectfor an existing bridge anti-collision structure is solved.

Description

technical field [0001] The invention belongs to the technical field of bridge protection, in particular to a bridge anti-collision structure with a bridge pier protection function. Background technique [0002] The intermediate support structure of a multi-span bridge is called a pier. The pier is divided into solid pier, column pier, and bent pier, etc., and can be divided into rectangular pier, pointed pier, and circular pier according to the plane shape. The materials for building pier can be Wood, stone, concrete, reinforced concrete and steel, etc. At present, the piers of most navigable bridges in my country do not have anti-collision facilities, and it is difficult to avoid the huge damage caused by ship collision accidents. Therefore, from the perspective of safety, economy and environmental protection, Designing an economical and reasonable bridge anti-collision device is an urgent problem to be solved. [0003] The traditional bridge anti-collision structure uses a ...

Problems solved by technology

[0004] The purpose of the present invention is to provide a bridge anti-collision structure with pier protection function, through the friction between the filling bag and the ship, the buffer belt is driven around the transmission roller to unload the force, through the cooperation of the filler in the filling bag and the gas in the inflatable bag Use the first cushioning, the second cushioning by the elastic force and tension provided by the second spring, the third cushioning by the elastic force generated by the first spring, and the third cushioning by the combination of rubber plate and closed-cell foam aluminum plate Four times of buffering, which solves the problem that the protection effect of the existing bridge anti-collision structure is not good
