Abstract
The utility model relates to an anticollision buffer. The anticollision buffer comprises a buffer base. The anticollision buffer is characterized in that mounting shafts are arranged on the left side and the right side of the buffer base, rotary arms are fixedly connected on the mounting shafts, a spring is connected between the outer top ends of the two rotary arms, force arms are connected with the top ends of the outer sides of the rotary arms through shaft pins, the two force arms are splay, a buffering board is connected with a small opening which is splay and is formed at the front ends of the force arms, and the front end and the rear end of each force arm are connected through a spring. The anticollision buffer is characterized in that buffer air springs are installed in the middle of the force arms. The anticollision buffer has the advantages of being capable of buffering impact on the front side, forming release force in the horizontal direction, and ensuring that the impact force does not directly transmit to a bridge pier along the direction of impact.
Description
Technical field
The utility model relates to a kind of anticollision bumper absorber.
Background technology
The increase of and navigating ship increasing along with the construction of bridge at present; the accident of a lot of ship collision bridge piers has taken place; in order to prevent the ship collision bridge pier; some places arrange guard column in bridge pier the place ahead; boats and ships are departed from toward the bridge pier bump time; and the safety of protection bridge pier; but owing to have a lot of parameters between the bump of the setting of guard column and boats and ships; therefore still can take place to strike bridge pier again behind the ship collision guard column; bridge is caused danger, and the serious bridge collapse that causes is therefore in order to protect the safety of bridge pier; still be necessary at bridge pier anticollision bumper absorber to be set, protect the safety of bridge pier at last.
Summary of the invention
The purpose of this utility model is to solve the guard column that bridge pier the place ahead arranges in the prior art still can't protect bridge pier to avoid the existing problem of ship collision, and a kind of anticollision bumper absorber is provided.The utility model designs a kind of anticollision bumper absorber, comprise buffer base, it is characterized in that: the right and left arranges installation shaft on buffer base, be fixedly connected with pivoted arm on the installation shaft, be connected with a spring between the outer end of two pivoted arms, the top, the outside of pivoted arm connects an arm of force by pivot pin, and two arm of forces are the interior Eight characters, arm of force front end is that the little opening part of the interior Eight characters connects a buffer board, and arm of force front end is connected by spring between the rear end.It is characterized in that: the cushion gas spring is installed in the middle of the arm of force.The utility model has the advantages that and the bump in front can be cushioned, and form the release force of a horizontal direction, guarantee that impact does not directly pass to bridge pier along crash direction.
Description of drawings
Accompanying drawing is structural representation of the present utility model.
Below in conjunction with accompanying drawing and construction embodiment the utility model is made detailed operation instruction.
The specific embodiment
Comprise buffer base 1 among the figure, it is characterized in that: the right and left arranges installation shaft 2 on buffer base, be fixedly connected with pivoted arm 3 on the installation shaft, be connected with a spring 4 between the outer end of two pivoted arms, the top, the outside of pivoted arm connects an arm of force 5 by pivot pin, two arm of forces are the interior Eight characters, and arm of force front end is that the little opening part of the interior Eight characters connects buffer board 6 by pivot pin 7.It is characterized in that: cushion gas spring 8 is installed in the middle of the arm of force.
Snubber is installed in waterline place on the bridge pier in face of the direction of shipping agency, under snubber, floating drum is installed, and is fixed by hawser, when water level rises or descend, snubber is fluctuated, guarantee that snubber is positioned at the waterline place on the bridge pier all the time.When the generation boats and ships take place with the bridge pier bump because going partially, the head of boats and ships strikes on the buffer board earlier, the stressed retraction of buffer board, buffer board at first compresses the cushion gas spring, and then continue to promote backward arm of force retraction, and the related pivoted arm of the arm of force rotates around installation shaft, and arm of force rear end band pivoted arm after installation shaft is rotated, the arm of force will compress spring, and the impact that the rectilinear direction in the place ahead is come decomposes on two springs between the pivoted arm.And the huge impact that makes is not applied directly on the bridge pier.The cushion gas spring that is hit can slowly have a resilience, is equivalent to can produce a damping when the collision of ship.
If when bump, ship is the angular impingement buffer board, and then because buffer board and the arm of force are being connected of pivot pin with pivoted arm, so buffer board can be partial to thereupon, can guarantee that also bridge pier is not by the hull side impact.
If it is very big that the local height of water of snubber is installed, can consider to adopt the guide rail that vertical direction is installed at bridge pier, use a connecting rod then, a connection snubber, the other end connects the slide block in the guide rail, so along with the lifting of water level, the floating drum band snubber and is fluctuated, and floating drum is connected on the guide rail and can does not waft by being connected bar.
Claims (2)
1. anticollision bumper absorber, comprise buffer base, it is characterized in that: the right and left arranges installation shaft on buffer base, be fixedly connected with pivoted arm on the installation shaft, be connected with a spring between the outer end of two pivoted arms, the top, the outside of pivoted arm connects an arm of force by pivot pin, and two arm of forces are the interior Eight characters, arm of force front end is that the little opening part of the interior Eight characters connects a buffer board, and arm of force front end is connected by spring between the rear end.
2. by the described a kind of anticollision bumper absorber of claim 1, it is characterized in that: the cushion gas spring is installed in the middle of the arm of force.
