Description

Bridge post collision avoidance device

Technical Field

The utility model relates to a bridge protection technical field particularly, relates to a bridge pillar collision avoidance device.

Background

With the increase of the number of bridges, the increase of the size of ships and the increase of the speed of ships, the risk that the bridges are impacted by the ships is gradually increased.

There are three factors that cause a ship to bump into a bridge: firstly, human factors including working negligence, misoperation, insufficient technical capability, error in personnel cooperation and the like; mechanical faults comprise that the main engine is stopped, the ship loses power, the steering engine is out of order, the ship cannot work according to normal steering instructions and the like; and thirdly, natural environments comprise natural factors such as channel parameter change, weather, flood, bridge area channel environment and the like. Considering from the angle of bridge self protection, can design the protective layer or utilize some special materials to protect the bridge, but often the effect is bad and satisfactory, do not have a suitable method to protect the bridge, and simultaneously, present protection mode is mainly that pier substructure below the bridge adds establishes flexible anticollision, because the difference of ship type and collision pressure size, be greater than the flexible crashproof effect under the circumstances of power to pier superstructure and boats and ships impact, basically can not play the effect of protection, simultaneously, at actual working process, can meet the bridge column structure of different shapes, especially square bridge column, also do not have a suitable method to carry out reasonable anticollision protection to square bridge column.

An effective solution to the problems in the related art has not been proposed yet.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide a bridge post collision avoidance device to solve the problem that proposes among the above-mentioned background art.

In order to achieve the above object, the utility model provides a following technical scheme:

the utility model provides a bridge post collision avoidance device, includes the bridge post, the bridge post surface sets up a plurality of planting bars, the welding of planting bar outside has circular track bottom plate, the circular track bottom plate outside is provided with circular track, the circular track outside is provided with the protective layer, be provided with the pulley in the middle of protective layer and the circular track, the base welding of pulley is on circular welt, the circular welt outside is provided with the protective layer, the pulley can be on circular track clockwise or anticlockwise free slip.

Further, the bridge column is a square bridge column.

Further, at least two of the circular tracks are included.

Further, the inner side of the protective layer is connected with the circular lining plate through rivets.

Furthermore, the protective layer is made of a thermoplastic rubber layer.
