Abstract

The invention relates to a protecting device of a wholesale bridge pillar that has the following structure: an impact wheel is movably fixed at the front end of a buffer push rod, a lateral protecting board is connected with a flexible jointing board, the buffer push rod is connected with a movable water gate board through a connecting rod, an air-actuated drive rod is arranged on the movable water gate board and connected with other air-actuated drive rod through a reverse wheel, the lateral protecting board is connected on a sealed float chamber through the connecting rod, and through the sealed float chamber, the protecting device ascends and descends along with the rising and falling of water level, floats on water, and can always be protective regardless of the height of the water level. The protecting device of the wholesale bridge pillar can always be protective when the wholesale bridge pillar is impacted by various boats from different directions, and has simple structure andeasy implementation.

Description

technical field [0001] The invention relates to a protection device for a bridge pontoon, in particular to a protection device for counteracting the force of a ship hitting a bridge pontoon. Background technique [0002] In the past, due to various objective reasons, the bridge construction in our country failed to consider the collapse of the bridge due to various external forces during the design and construction process. Patent 200580000042.4 discloses a bridge protection device, which includes sacrificial parts and restraint parts. The sacrificial parts include: beams, which are installed on the upper surface of the abutment or the abutment of the pier to support the bridge deck; symmetrical main supports, which connect the two beams and have a tubular structure; The axial direction of the main support protrudes from the central part of the main support in a direction perpendicular to the axis; the restraining member is fixed on the bridge support of the abutment or brid...
