Description
Technical Field
The invention relates to the technical field of bridge protection, in particular to a bridge post anti-collision protection 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 apply some special materials and protect the bridge, but often the effect is bad and happy, does not have a suitable method and protects the bridge, and simultaneously, present protection mode is mainly to add at pier substructure and establishes flexible anticollision, because the difference of ship type and collision pressure size, is greater than under the flexible crashproof power condition to pier superstructure and boats and ships impact, does not play the effect of protection basically.
An effective solution to the problems in the related art has not been proposed yet.
Disclosure of Invention
The invention aims to provide a bridge pillar anti-collision protection device to solve the problems in the background technology.
In order to achieve the purpose, the invention provides the following technical scheme:
the utility model provides a bridge post collision avoidance device, includes bridge and pier post, the bearing has been cup jointed in the pier post outside, the installation of pier post is hugged closely to the bearing inner circle, the outer lane riveting of bearing is in the inboard of protective layer, increase epitaxial antenna on the protective layer, the antenna can be around the protective layer round or be semicircle-shaped setting towards the channel part along the protective layer, protective layer and antenna follow when pier post bumps with the ship the outer lane of bearing is rotatory together.
Furthermore, both sides of the antenna are in a curve shape, and the antenna is made of rigid and flexible materials, so that when the antenna is deformed in collision, steering force can be provided for the bearing to form rotation.
Further, the antenna may be disposed in a perpendicular direction to an outer tangent of the protective layer.
Further, the antenna may be disposed in an oblique direction to an outer tangent of the protective layer.
Further, the antenna may rotate clockwise or counterclockwise around the pier column when the ship collides with the pier column.
Furthermore, the material of the protective layer is a thermoplastic rubber layer.
Further, the pier stud is of a cylindrical structure.
The working principle of the invention is as follows: this device can push down the bearing rotation under the effect of power when the ship bumps to the pier, increases epitaxial antenna on the protective layer that the device outside set up, and the effect of this antenna provides horizontal pivoted power after the collision, realizes the function of this device rotation off-load, plays the effect of buffering to the effort of ship striking bridge to alleviate the effort of ship striking pier stud, protection ship and bridge upper part are damaged less, and furthest's protection shipboard personnel do not receive the bruise simultaneously.
Compared with the prior art, the invention has the following beneficial effects: 1. the device has simple structure, convenient installation and easy realization; 2. the device utilizes the rotary structure of the bearing, an extended antenna is added on a protective layer arranged on the outer side of the device, and the acting force of transverse rotation of a ship when the ship is impacted is increased, so that the unloading function is realized, the pier column and the bridge are protected to the maximum extent, and meanwhile, the ship and personnel passing by are protected from being damaged; 3. the device has the advantages of ingenious design and novel structure; 4. the device has wide application, is not only suitable for protecting the pier column, but also suitable for protecting the pier structure.

Detailed Description
The invention is further described with reference to the following drawings and detailed description:
as shown in fig. 1-3, a bridge post collision avoidance device, including bridge and pier post 1, bearing 2 has been cup jointed in the 1 outside of pier post, 2 inner circles of bearing hug closely the installation of pier post 1, the outer lane riveting of bearing 2 is in the inboard of protective layer 3, increase epitaxial antenna 4 on the protective layer 3, antenna 4 is half circular setting towards the channel part along protective layer 3, protective layer 3 and antenna 4 follow when pier post 1 bumps with the ship the outer lane of bearing 2 is rotatory together.
According to the above, the two sides of the antenna 4 are curved. The antenna 4 is set to be in a curve shape, so that the acting force generated when the pier stud 1 collides with a ship can be better converted.
According to the above, the antenna 4 may be disposed in a perpendicular direction to an outer tangent of the protective layer 3.
According to the above, the antenna 4 may rotate clockwise or counterclockwise around the pier stud 1 when the ship collides with the pier stud 1. The feeler 4 can rotate under the deformation force effect of two kinds of hard and soft materials when boats collide with the pier stud 1, because the outer lane of bearing 2 can be followed clockwise or anticlockwise rotation, so feeler 4 also can be around pier stud 1 clockwise or anticlockwise rotation.
According to the above, the material of the protective layer 3 is a thermoplastic rubber layer. The thermoplastic plastic layer has the advantages of good elasticity, compression deformation resistance and convenience in processing, so that energy can be better absorbed in collision, and the thermoplastic plastic layer is more convenient to process and replace.
According to the above, the thermoplastic rubber plastic layer is a polyethylene layer. The polyethylene layer has corrosion resistance and oxidation resistance, and is suitable for places with high humidity.
According to the above, the pier stud 1 is a cylindrical structure. The pier stud 1 is of a cylindrical structure and is convenient for the bearing 2 to be sleeved.
