Description
Technical Field
[0001] The utility model belongs to the technical field of ship construction facilities, and particularly relates to a floating pier anti-collision buffer device. Background Art
[0002] When using construction ships such as cutter suction dredgers and trailing suction hopper dredgers for construction, an inevitable problem is that the ship passes under an existing bridge, and a passage for the ship to pass through is formed between adjacent piers of the bridge. When passing the bridge, the construction ship should reduce its speed and pass by relying on its own navigation ability or with the assistance of an auxiliary ship such as an anchor boat. Especially for a non-powered ship, due to its weak ability to maintain its own attitude and movement parameters, other auxiliary means are more needed. During the process of the ship passing the bridge, it is necessary to provide protective measures for the pier. In special cases, when the ship moves towards the pier and inevitably contacts the pier, the aforementioned protective measures should play a sufficient buffering effect to avoid the ship from colliding with and squeezing the pier, so as to protect the pier from damage and ensure the safety of the bridge.
[0003] The existing pier anti-collision buffer measures are usually anti-collision blocks installed on the pier or large facilities installed outside the pier that can move up and down synchronously with the water level. The aforementioned facilities are all permanent facilities, usually installed on the piers of bridges on busy waterways to resist potential ship collisions when passing the bridge. However, as mentioned above, in some specific scenarios of non-waterways, no anti-collision buffer facilities are configured for the piers of the bridge due to the lack of the need for frequent ship passage. In the passage scenarios of construction ships such as cutter suction dredgers and trailing suction hopper dredgers, it is necessary to consider temporarily adding anti-collision buffer facilities to reduce the risks borne by the bridge. This requires providing a new type of anti-collision buffer facility that can be flexibly arranged and removed and is easy to transfer with the ship, quickly arranged before passing the bridge and quickly removed after passing. Such facilities do not exist in the prior art and need to be developed and designed specifically. Summary of the Utility Model

[0005] The technical solution adopted by the utility model is as follows: A floating pier anti-collision buffer device is formed by connecting multiple floating anti-collision segments in series to form a circular shape.

[0011] The advantages and positive effects of the utility model are:
[0012] The utility model provides a floating pier anti-collision buffer device, which is a temporary facility built on the outside of the pier when a ship passes through the bridge to reduce the potential risk of collision loss of the pier. Since it is a floating facility, it can change its height with the change of the water level. Compared with the existing pier anti-collision buffer facilities, the anti-collision buffer device of the utility model is formed by connecting a plurality of floating anti-collision segments in series with connecting chains to form a circular shape.

DETAILED DESCRIPTION OF THE EMBODIMENTS
[0019] In order to further understand the invention content, features and effects of the utility model, the following embodiments are given for detailed description.
[0020] Please refer to Figure 1 、 Figure 2 and Figure 3 , the floating pier anti-collision buffer device of the present utility model is formed by connecting multiple floating anti-collision segments in series into an annular shape. Adjacent floating anti-collision segments are connected by multiple connecting chains 3. The end of the connecting chain 3 is detachably connected to the floating anti-collision segment. The pier 5 is located inside the device. This pier anti-collision buffer device floats on the water surface by itself and changes its height with the change of the water level. The annular anti-collision buffer device provides the function of anti-collision buffer on the outside of the pier 5. When a ship crossing the bridge approaches the pier 5, the floating anti-collision segment is located between the ship and the pier 5 and is subjected to extrusion. Under the action of its own elasticity, the floating anti-collision segment can effectively prevent the ship from directly colliding with the pier 5, and resolve the extrusion of the ship on the pier 5 by providing a buffering effect, achieving the role of protecting the pier 5 and the bridge.
[0021] As Figure 1 shown, there are two piers 5 on the inner side of the annular floating pier anti-collision buffer device. The principle applied is that the bridge is supported by multiple groups of piers 5 arranged along the length direction, and each group of piers 5 includes two piers 5 arranged along the width direction of the bridge. Therefore, this anti-collision buffer device is configured for two adjacent groups of piers 5 of the bridge. At the position of each group of piers 5, the annular anti-collision buffer device is located outside the two piers 5 at this position. Of course, it can be imagined that an annular anti-collision buffer device can also be configured for each pier 5.
[0022] The floating anti-collision segment, as a single component, is not further disassembled when the floating pier anti-collision buffer device is disassembled. Therefore, this floating pier anti-collision buffer device can be disassembled into multiple floating anti-collision segments and connecting chains 3. Since the connecting chain 3 is detachably connected to the floating anti-collision segment, when constructing this device on the pier 5 and removing this device from the pier 5, only the connecting chain 3 needs to be connected / disconnected from the floating anti-collision segment.
[0023] Please refer to Figure 2 , it can be seen that:
[0024] The floating anti-collision segment includes an outer sleeve 1. End blind plates 6 with windows 6-1 in the middle are installed at both ends of the outer sleeve 1. An airbag 2 is installed inside the outer sleeve 1. The airbag 2 is used to provide buoyancy, and the outer sleeve 1 is used to provide protection for the airbag 2 to prevent the airbag 2 from being directly squeezed by the ship and the pier 5.
[0025] The airbag 2 comprises an airbag body 2-1 and an inflation tube 2-3 connected to the airbag body 2-1. The inflation tube 2-3 extends through a window 6-1 and is equipped with an inflation nozzle 2-4 at its end. The end of the airbag 2 is connected to the blind plate 6 on this side by a connecting rope 7. Before the device is deployed on the bridge pier 5, the air pressure of the airbag 2, that is, the degree of inflation, can be adjusted as needed. To lower the pressure, the air is released through the inflation nozzle 2-4. To increase the pressure, an air compressor is used to inject an appropriate amount of air into the airbag.
[0026] Connecting cord 7 is used to hold airbag 2 in the center of outer sleeve 1. In this embodiment, end collars 2-2 are located at the center of each end of airbag body 2-1 of airbag 2. Connecting cord 7 passes through end collars 2-2. Threaded rods are provided at each end of connecting cord 7. These rods pass through connection holes in end blind plates 6 and are secured with nuts. As shown in the figure, connecting cord 7 is V-shaped. The connecting cords 7 on both sides provide tension to airbag 2, thereby keeping airbag 2 in the center of the inner cavity of outer sleeve 1.
[0027] like Figure 2 As shown in , it can be seen that:
[0028] The outer sleeve 1 includes a steel mesh lined hose 1-1 located in the middle. End steel pipes 1-2 are provided at both ends of the steel mesh lined hose 1-1. Flanges 1-3 are provided at the outer ends of the end steel pipes 1-2. The end blind plates 6 are rubber plates, the edges of which are fixedly connected to the flanges 1-3. The end steel pipes 1-2 are flat, and their axial length is much shorter than that of the steel mesh lined hose 1-1. The steel mesh lined hose 1-1 is a hose with a steel mesh interior. It possesses both strong structural strength and a certain degree of flexibility. When the floating anti-collision segment is squeezed by ships and bridge piers 5, the steel mesh lined hose 1-1 can deform. When the deformation reaches a certain level, the internal airbag 2 is also squeezed.
[0029] The end steel pipe 1-2 is used to maintain the end shape of the lined steel mesh hose 1-1, and the flange 1-3 is used to be fixedly connected to the end blind plate 6. When the outer sleeve 1 is squeezed, the water and air inside it will be discharged through the window 6-1 on the end blind plate 6. When the squeezing effect on the outer sleeve 1 disappears, it will restore its shape under the action of its own elastic force. At this time, air and water can re-enter the interior of the outer sleeve 1 through the window 6-1.
[0030] In this embodiment, the end blind plate 6 and the flange 1-3 are fixedly connected by a plurality of connecting collar rings 8. The connecting collar ring 8 includes a threaded rod and a collar at the end of the threaded rod. A plurality of connecting holes are provided on the end blind plate 6 and the flange 1-3. The threaded rod of the connecting collar ring 8 is located in the connecting hole and is locked and fixed by a nut. The collar of the connecting collar ring 8 is located on the outside. Therefore, the connecting collar ring 8 has two functions. One function is to fixedly connect the end blind plate 6 and the flange 1-3, and the other function is to provide a collar required for connecting with the connecting chain 3.
[0031] Please refer to Figure 3 , it can be seen that:
[0032] The connecting chain 3 includes a chain body 3-1. A first hook 3-2 is provided at one end of the chain body 3-1, and a second hook 3-3 is provided at the other end. The first hook 3-1 is hooked and connected to the connecting collar ring 8 of the previous floating anti-collision segment, and the second hook 3-3 is hooked and connected to the connecting collar ring 8 of the next floating anti-collision segment. As shown in the figure, both the first hook 3-2 and the second hook 3-3 are provided with anti-disengagement elastic pieces. After being hooked and connected to the connecting collar ring 8, the anti-disengagement elastic pieces rebound to close the opening of the hook, preventing the chain petals of the chain body 3-1 from slipping out by themselves.
[0033] It further includes a hoop 4 provided on the pier 5. The floating anti-collision segment located outside the pier 5 is connected to the hoop 4 by a connecting chain 3. By providing a hoop 4 on the pier 5 and using a connecting chain 3 to fixedly connect the nearby floating anti-collision segment to the hoop 4, the anti-collision and buffering device has a certain anchoring effect, avoiding any movement under the action of water flow. The connecting chain 3 connecting the hoop 4 and the floating anti-collision segment is exactly the same in structure as the connecting chain 3 connecting adjacent floating anti-collision segments.
[0034] In this embodiment, a connecting collar ring 8 is installed on the outside of the hoop 4. The structure of the connecting collar ring 8 here is the same as that of the connecting collar ring 8 on the floating anti-collision segment. Its threaded rod is installed and fixed on the outside of the hoop 4 by welding. A side collar 1-4 is provided in the middle of the outer wall of the outer sleeve 1. The first hook 3-1 of the connecting chain 3 is hooked and connected to the connecting collar ring 8 on the hoop 4, and the second hook 3-3 of the connecting chain 3 is hooked and connected to the side collar 1-4 of the outer sleeve 1.
[0035] Arrangement method:
[0036] This floating pier anti-collision buffer device is transferred with the ship in a disassembled state. That is to say, this floating pier anti-collision buffer device is disassembled into floating anti-collision segments, connecting chains 3 and hoop 4, and carried by auxiliary ships such as anchor boats. After determining the bridge-crossing plan of the construction ship, the auxiliary ship moves to the pier 5 first to install this device; before installation, first confirm the air pressure condition of the airbag 2 of each floating anti-collision segment, and inflate or deflate according to the needs to adjust and set the air pressure.
[0037] First, install the hoop 4 on the pier 5, then use the connecting chain 3 to gradually connect the floating anti-collision segments in series to form a ring, and then use the connecting chain 3 to connect the floating anti-collision segments outside the pier 5 with the hoop 4.
