[0002] Bridge anti-collision devices are special facilities used to protect bridges from ship collisions.
[0003] At present, the anti-collision device using solid anti-collision material as the main structure provides a limited anti-collision buffer distance, which causes the bridge pier to be directly subjected to force in advance, thereby causing the protection of the bridge pier to fail. Utility Model Content
[0004] The purpose of the utility model is to solve the above-mentioned problems and to propose an anti-collision device with an array-type circular tube filling structure.
[0005] In order to achieve the above-mentioned purpose, the present invention adopts the following technical solution: an anti-collision device with an array-type circular tube filling structure, comprising:
[0006] A plurality of inner circular tubes are arranged in a circular array around the pier;
[0007] a first fixing hoop, which covers the plurality of inner circular tubes;
[0008] a first wedge-shaped strip, which is clamped on the first fixing hoop;
[0009] a second fixing hoop, which is sleeved around the first wedge-shaped strip;
[0010] a second wedge-shaped strip, which is clamped on the second fixing hoop;
[0011] A plurality of buffer cylinders are distributed in an annular array between the first fixing hoop and the second fixing hoop, and the first wedge strip and the second wedge strip are both inserted into the plurality of buffer cylinders.
[0012] As a further description of the above technical solution:
[0013] The end of the first fixing hoop and the end of the second fixing hoop are both connected by a fixing bolt.
[0014] As a further description of the above technical solution:
[0015] A C-shaped slot is formed on the inner wall of the first wedge-shaped strip, and the first fixing hoop is inserted into the C-shaped slot.
[0016] As a further description of the above technical solution:
[0017] The buffer cylinder is a cylindrical shell, and two piston blocks slide inside the buffer cylinder. Two air-avoiding grooves are opened on the side of the buffer cylinder. The first wedge strip and the second wedge strip pass through the two air-avoiding grooves respectively and are inserted between the two piston blocks.
[0018] As a further description of the above technical solution:
[0019] An edge of the piston block is provided with an inclined surface, and the inclined surface coincides with a surface of the first wedge strip and a surface of the second wedge strip.
[0020] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are:
[0021] 1. In the utility model, a buffer support in contact with the bridge pier is provided by the inner circular tube, and a plurality of buffer cylinders are limited between the first fixing hoop and the second fixing hoop. When the second fixing hoop is hit, the first wedge bar and the second wedge bar gradually approach and are stuck in the buffer cylinder. The buffer cylinder provides a buffering effect, and the overall structure provides a sufficiently large buffer distance to prevent the bridge pier from being directly subjected to force in advance, thereby having a good protective effect on the bridge pier.
[0022] 2. In the utility model, when the second fixing hoop is hit, under the premise of the buffering support of the inner tube, the first wedge bar and the second wedge bar gradually approach and are stuck in the buffer cylinder, and the piston block slides in the cylindrical shell and compresses the internal air, thereby buffering the sliding of the first wedge bar and the second wedge bar, providing a sufficiently large buffer distance, and preventing the bridge pier from being directly subjected to force in advance, thereby having a good protective effect on the bridge pier.
