Abstract
The invention relates to a height-limiting anticollision device of a bridge. The height-limiting anticollision device comprises bridge-type height-limiting anticollision frames (2), longitudinal frames (3) and linear movement mechanisms (4), the bridge-type height-limiting anticollision frames (2) arranged in the front and rear water of one bridge (1) are in rigid connection with the longitudinal frames (3) penetrating a bridge opening and located on two sides of a channel, the linear movement mechanisms (4) are on channel piers (6) or anticollision piers (6) on two sides of the channel of the front and rear water of the bridge (1) or arranged on bank bases (7) of both banks of the channel of the front and rear region of the bridge (1), and shock absorbers (5) are arranged at both ends of each linear movement mechanism (4). The height-limiting anticollision device has the technical advantages that when the height of a ship is over the clear height of the bridge (1), after the bridge-type height-limiting anticollision frames (2) are collided with the ship, carriages (41) on the linear movement mechanisms (4) are pushed, the shock absorbers (5) are compressed to act to dissipate collision energy of the ship so as to protect the bridge, and the bridge-type height-limiting anticollision frames restore under the action of restoration face of the shock absorber; when the height of the accident ship is below the clear height of the bridge (1), the ship collides with the side edges of the channel of the longitudinal frames (3) during yawing and deflection, and the heading of the ship is corrected.
Description
Technical field
The ship that the present invention relates to bridge crane span structure hits resist technology, particularly relates to the height-limiting anticollision device of bridge crane span structure.
Background technology
Along with the development of transportation, in a large number over strait, constantly build across river, crossing bridge.And the residing river of this bridge itself, river, lake, marine site are mostly busy navigation channels, the situations such as its current, great waves, stormy waves are complicated, and bridge inevitably carries the risk of certain ship collision.Under non-situation, boats and ships grazing or when clashing into the crane span structure of bridge, the momentum with the boats and ships of certain speed is very large, according to momentum theorem: mv1-mv2=F Δ t, Δ t are moments, and thus its impact is huge, damages bridge and happens occasionally.
At present, are crane span structures of arc at the crane span structure great majority of the bridge of rivers,lakes and seas, during the passing bridge opening of ship, ship top exceeds bridge depth of beam, collides with crane span structure; Collision crane span structure is affected by following factor: the uncertainty at tide sunset; The change of tidewater; The variation of current; The change in navigation channel; The change of stormy waves weather; Marine technology situation and pseudo-rule operation; Navigate by water under the non-states such as crew quality is low, human pilot awareness of safety and mood, occur that ship is just inserted, just hit, side impact, side hit, deflect shock, therefore the crane span structure of bridge must arrange height-limiting anticollision device, the safety of protection bridge.
During the passing bridge opening of ship, because of some reason, ship is travelled and there occurs skew or deflection, make the crane span structure of vessel-bridge collision.So the crashproof anticollision device, collision-prevention device of limit for height of navigation correction must be arranged at the crane span structure of important bridge.
Summary of the invention
Technical problem to be solved by this invention is present situation for prior art and provides a kind of height-limiting anticollision device of vessel bump bridge frame; it effectively can protect ship and clash into bridge crane span structure; bridge crane span structure inside anticollision device, collision-prevention device is played a protective role; and require that height-limiting anticollision device is sturdy and durable; easy installation, easy maintaining and repairing.
The present invention solves the problems of the technologies described above adopted technical scheme: a kind of height-limiting anticollision device of crane span structure, it is characterized in that: comprise before being arranged on crane span structure, the bridge-type limit for height bumper frame being parallel to crane span structure in rear waters, be connected rigidly with the longitudinal frame of the both sides, navigation channel through bridge opening, before being arranged on crane span structure, on the navigation channel pier of the both sides, navigation channel in rear waters or crash bearer or before being arranged on crane span structure, linear moving mechanism on the bank base of the two sides, navigation channel of rear region, at the two ends of linear moving mechanism, buffer is set, wherein, on the planker that two of bridge-type limit for height bumper frame is erected at linear moving mechanism or slide block, the planker of linear moving mechanism or the face, rear and front end of slide block contact with buffer tightly, or the front-back at two of bridge-type limit for height bumper frame contacts with buffer tightly, wherein, clear height and the crane span structure clear height of bridge-type limit for height bumper frame are contour, the shape of bottom surface of bridge-type limit for height bumper frame conforms to the shape of the bottom surface of crane span structure.
The linear track travel mechanism that above-mentioned linear moving mechanism is made up of the track of planker or slide block and straight line.
The straight travel mechanism that above-mentioned linear moving mechanism is made up of the chute of planker or slide block and straight line.
Secondary buffer is laid in the outside of above-mentioned bridge-type limit for height bumper frame.
The navigation channel side of the longitudinal frame of the above-mentioned both sides, navigation channel through bridge opening presents the head on fusiform head or the chevron inclined-plane expanded outwardly.
The navigation channel side of the longitudinal frame of the above-mentioned both sides, navigation channel through bridge opening lays the roller devices of energy dissipating of navigating.
Compared with prior art, the invention has the advantages that: the clear height and the shape that are arranged on the bottom surface of the bridge-type limit for height bumper frame in the forward and backward waters of crane span structure are equal to crane span structure, exempt ship and hit incision; When accident ship is higher than crane span structure clear height, after bridge-type limit for height bumper frame is hit by ship, promote the planker on linear track, compression cushioning device work done, consume ship and hit energy, ship slows down, berths, thus protect crane span structure, ship stops after ship hits, bridge-type limit for height bumper frame and planker under the effect of the returning place force of buffer, return; When accident ship is lower than crane span structure clear height, during driftage, when bumping against the fusiform head expanded outwardly of the navigation channel side of longitudinal frame, ship is guided, and corrects course, enters navigation channel; The navigation channel side of longitudinal frame lays the roller devices of energy dissipating of navigating, and the course of ship of effectively rectifying a deviation and the deflection of ship in bridge opening, make boat trip at middle channel.
