Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of bridge pier anti-collision, in particular to a composite material bridge anti-collision device. Background Art
[0002] The construction of cross-river and cross-sea bridge projects is developing rapidly. my country has built a trunk road network that runs from north to south and from east to west. The construction of large bridges can relieve traffic pressure and promote land transportation. However, for water vessels, bridges are artificial obstacles. Due to many factors such as the natural environment, navigation environment, ship conditions, ship operators and managers, vicious accidents involving collisions between ships and bridges occur from time to time. In order to ensure the safe operation of bridges, various bridge anti-collision devices have emerged.
[0003] However, although the current composite bridge anti-collision device can prevent ships from directly contacting and colliding with bridge piers and reduce the impact force of some ships on bridge piers, due to the rigid connection between it and the bridge support column, a large impact force will still be transmitted to the bridge pier through the device, and the buffering effect is general. Utility Model Content
[0004] The utility model aims to solve the problem that the current composite material bridge anti-collision device has a general buffering effect due to the rigid connection between the composite material bridge and the bridge pier, and proposes a composite material bridge anti-collision device.
[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:
[0006] A composite material bridge anti-collision device includes two groups of installation components, the installation components include a fixing ring and a mounting plate, the mounting plate is annular and fixedly sleeved on the outside of the fixing ring, the two fixing rings are respectively fixedly sleeved on the bottom and the upper end of the pier, the two mounting plates are each provided with a mounting ring on the side close to each other, a plurality of springs are provided between the mounting ring and the fixing ring, the two ends of the spring are respectively fixedly connected to the fixing ring and the mounting ring, a plurality of rotating shafts are provided between the two mounting rings, a mounting rod is provided on the side of the mounting ring close to the rotating shaft, the mounting rod and the mounting ring are integrally formed, and a mounting groove matching the mounting rod is provided at the end of the rotating shaft.
[0007] Preferably, the plurality of springs are located in the radial direction of the fixing ring and are evenly distributed between the fixing ring and the mounting ring.
[0008] Preferably, a plurality of ball grooves are formed on one side of the mounting ring close to the mounting plate, and round balls are installed in the ball grooves, and the round balls are in rolling contact with the mounting plate.
[0009] Preferably, the plurality of rotating shafts are evenly distributed between the two mounting rings, and a buffer sleeve is sleeved on the rotating shaft, and the buffer sleeve is made of rubber material.
[0010] Preferably, the mounting rod is conical, and the cross section of one side away from the mounting ring is smaller than that of the other side, and the shape of the mounting groove is the same as that of the mounting rod.
[0011] Preferably, a tapered bearing is fixedly sleeved on the mounting rod, and an outer side wall of the tapered bearing contacts an inner wall of the mounting groove.
[0012] Compared with the prior art, the beneficial effects of the utility model are:
[0013] 1. When a ship collides with a rotating shaft, the rotating shaft will rotate along the direction of the force, which can change the forward direction of the ship to a certain extent, so that the angle between the ship and the pier radial direction increases. Since the impact force on the pier is the component force of the ship along the radial direction of the pier, the impact force on the pier will be reduced, which effectively protects the pier.
[0014] 2. Since the mounting ring and the fixing ring are connected by a spring, when a ship hits the device, the buffering effect of the spring greatly prolongs the force-bearing time of the pier, thereby reducing the force on the pier and avoiding the pier from being subjected to a large impact force in a short time.

[0019] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.
[0020] In the description of the present invention, it should be understood that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore should not be understood as a limitation on the present invention.
[0021] Reference Figure 1-3 A composite material bridge anti-collision device comprises two sets of mounting components, the mounting components comprising a fixing ring 2 and a mounting plate 3, the mounting plate 3 is annular and fixedly sleeved on the outside of the fixing ring 2, the two fixing rings 2 are respectively fixedly sleeved on the bottom and the upper end of the pier 1, the two mounting plates 3 are each provided with a mounting ring 4 on the side close to each other, a plurality of springs 5 are provided between the mounting ring 4 and the fixing ring 2, the two ends of the spring 5 are respectively fixedly connected to the fixing ring 2 and the mounting ring 4, the plurality of springs 5 are located in the radial direction of the fixing ring 2 and are evenly distributed between the fixing ring 2 and the mounting ring 4, a plurality of ball grooves are provided on the side of the mounting ring 4 close to the mounting plate 3, a round ball 9 is installed in the ball groove, and the round ball 9 is in rolling contact with the mounting plate 3;
[0022] A plurality of rotating shafts 6 are arranged between the two mounting rings 4, and the plurality of rotating shafts 6 are evenly distributed between the two mounting rings 4. A buffer sleeve 8 is sleeved on the rotating shaft 6, and the buffer sleeve 8 is made of rubber material. A mounting rod 7 is arranged on the side of the mounting ring 4 close to the rotating shaft 6, and the mounting rod 7 and the mounting ring 4 are integrally formed. A mounting groove 10 matching the mounting rod 7 is opened at the end of the rotating shaft 6. The mounting rod 7 is conical, and the cross-section of the side away from the mounting ring 4 is smaller than the other side. The shape of the mounting groove 10 is the same as that of the mounting rod 7. A tapered bearing 11 is fixedly sleeved on the mounting rod 7, and the outer wall of the tapered bearing 11 contacts the inner wall of the mounting groove 10.
[0023] When the utility model is used, it is installed on the pier 1. When a ship collides with the outer rotating shaft 6, since the mounting ring 4 and the fixing ring 2 are connected by the spring 5, the buffering effect of the spring 5 greatly prolongs the force-bearing time of the pier 1, thereby reducing the force on the pier 1. At the same time, since the rotating shaft 6 can rotate, when the ship collides with the rotating shaft 6, the rotating shaft 6 will rotate along the force direction, thereby changing the forward direction of the ship to a certain extent, so that the radial angle between the ship and the pier 1 increases. Since the impact force on the pier 1 is the component force of the ship along the radial direction of the pier 1, the impact force on the pier 1 will be reduced.
