Description

Ship collision protection device is prevented to bridge superstructure
Technical Field
The invention belongs to the technical field of bridge anti-collision, and particularly relates to a ship collision prevention protection device for a bridge superstructure.
Background
Along with the continuous development of bridge technology and transportation industry, bridges are erected above a plurality of channels, and when ships pass through bridge holes, the situations that the tops of the ships are higher than the bridge holes inevitably occur due to uncertain factors such as tides, stormy waves and the like, so that the ships collide with bridge frames.
However, the anti-collision protection of bridges in various countries is mostly focused on the aspects of bridge pier anti-collision and fender technologies, the anti-collision protection of bridges is rarely involved, some bridges protect the bridges, but the height limiting measures of land vehicles are basically used for reference, and the height limiting devices such as vehicle height limiting frames are arranged below the bridges, so that the protection effect of the height limiting devices on the bridges is not ideal. The reason is mainly that the similar device with better height limiting and anti-collision effects on vehicles with smaller tonnage can be realized because the tonnage of the freight ship is generally larger, and the similar device can not play a better role on the ship; meanwhile, because the water environment is more complex than that of land, the adaptability of the land height limiting device is poor, the installation and maintenance are inconvenient, and the ship cannot be effectively prevented from being impacted by the ship to be limited in height and crashproof.

Based on the problems mentioned in the background art, the invention provides a ship collision prevention protection device for a bridge superstructure, which is used for solving the problem that the current bridge height limiting device is difficult to resist ship impact.
The technical scheme adopted by the invention is as follows:
the utility model provides a bridge superstructure prevents ship and hits protection device, includes the mount pad on installation and the pier, install the bolster on the mount pad, be equipped with the support on the pier, erect the bridge floor on the support, the mount pad includes first base, first base fixed mounting is on the pier, slidable mounting has two wedge platforms that set up relatively on the first base, installs bumper shock absorber and second base between two wedge platforms, is equipped with on the second base with wedge platform assorted wedge surface, second base and wedge platform sliding contact, install the spacing knot that is used for preventing that the second base drops on the first base, a plurality of slot groups have been seted up to the second base, every slot group all includes a plurality of mounting grooves, the bolster is installed in the mounting groove, the bolster includes the slip table is installed at leaf spring both ends, all wear to be equipped with the guide arm on the slip table, install the roof on the guide arm, install damping spring between roof and the slip table.
Based on the technical scheme, the invention also improves the following steps:
further, the mounting grooves of two adjacent groove groups are distributed in a staggered manner. The plate springs in the adjacent groove groups are distributed in a staggered mode, and the ship is prevented from directly striking the second base between the two plate springs.
Further, universal balls are mounted on the sliding table. The friction resistance between the sliding table and the mounting groove is reduced through the universal balls, so that the two ends of the plate spring are easier to stretch to the two sides at the moment of impact, and the buffer effect is improved.
Further, the first base is connected with an installation hoop, the installation hoop is sleeved on the pier, and a first buffer cushion is installed between the installation hoop and the pier. The first base is convenient to install, and meanwhile the damage to the bridge pier caused by the installation hoop when the first base is impacted by the action of the first buffer cushion is avoided.
Further, a plurality of communication grooves are formed in the first base at equal intervals, the wedge is connected with mounting frames in the communication grooves, and the shock absorber is mounted between the two mounting frames. The damper and the wedge can be arranged on the opposite side of the first base, so that interference caused by the damper to movement of the second base can be avoided, and a plurality of fixed connection points can be arranged between the mounting frame and the wedge under the action of the communication groove, so that the mounting frame is not easy to bend when being stressed.
Further, a slope is arranged on the first base, and a second buffer cushion is arranged between the slope and the bridge deck. The first base can not bend and deform under the restriction of bridge floor when the atress, simultaneously owing to the contact surface of first base and bridge floor is great, and is provided with the second blotter with the bridge floor between, be difficult for leading to the bridge floor impaired when receiving the impact.
Further, an arch is mounted on the first base, and the arch is located above the second base. On the premise of not damaging the bridge deck structure, the arch frame can be provided with devices such as laser, radar, infrared liquid level meter, LED information board, tweeter, whistle, intelligent camera and the like.
The invention has the beneficial effects that:
when the ship is impacted by exceeding the limit height, the deformation of the plate spring expands to two sides to be contacted with two ends of the mounting groove, so that the impact force of the ship is decomposed in multiple directions for the first time; the pressure received by the second base after the first buffering forces the wedge to move to compress the shock absorber, the pressure received by the second base is decomposed again to perform the second buffering, the stress of the first base is reduced, and the bridge deck can be better protected.
