Description

Technical Field

[0001] The utility model belongs to the technical field of dock anti-collision, and in particular relates to an anti-collision device for temporary berthing of a large container ship at a dock. Background Art

[0002] As the total number of ships built in our factory continues to rise, the large-scale ships have become the development trend of our factory. Large container ships are subject to rolling during parking at the dock, so there is a risk of collision between the dock crane and the lashing bridge of large container ships. Our factory's dock is a beam-slab dock, and the dock foundation cannot meet the needs of changing large and extra-long dock fenders, which cannot meet the needs of large container ships temporarily docking at the dock. If piles are driven under the harbor to support the dock fender, the overall construction is difficult and the sea area approval cycle is long. Therefore, based on this situation, combined with the original mooring piles and fender structures of the dock, this extended fender tooling is designed. Summary of the invention

[0003] The technical problem to be solved by the utility model is to prevent the collision between the lashing bridge and the dock crane when a large container ship is temporarily docked at a dock, and to provide an anti-collision device which is simple to manufacture, convenient to operate, short in cycle and high in safety.

[0006] A lifting nose is also fixedly mounted on the bottom plate and top plate assembly, and the anti-collision device is load-bearing by connecting the cable pile and the lifting nose through a chain.

[0007] Furthermore, there are a plurality of main body support tubes, which are arranged in a zigzag shape between the bottom plate and top plate assembly.

[0008] Furthermore, a reinforcing elbow plate is fixedly installed at the connection between the main support tube and the base plate and top plate assembly.

[0009] Furthermore, a reinforcing plate is fixedly mounted on the bottom plate, and a plurality of connecting plates are fixedly mounted on the reinforcing plate.

[0010] Furthermore, a plurality of baffles are fixedly provided on a side of the bottom plate facing away from the top plate assembly.

[0011] Furthermore, a tensioner is installed on the chain, and the length of the chain is adjusted by the tensioner.

[0012] Furthermore, the anti-collision pad is made of rubber and is fixed to the surface of the top plate assembly by bolts.

[0013] The advantages and positive effects of the utility model are:

[0014] The utility model has a simple structure and is easy to operate, and reduces the load on the original fender. After calculation and testing, the device can be used for collision prevention when the ship is moored at the dock under a wind force 11. BRIEF DESCRIPTION OF THE DRAWINGS

[0020] Example 1

[0021] As shown in the figure, the present embodiment provides an anti-collision device for temporary docking of a large container ship at a dock, comprising a bottom plate 1 and a top plate assembly 4; the bottom plate 1 and the top plate assembly 4 are connected via a main support pipe 3, the bottom plate is fixedly connected to the original fender, and an anti-collision pad 11 is fixedly provided on a side of the top plate assembly 4 facing away from the bottom plate;

[0022] A lifting nose 7 is also fixedly mounted on the bottom plate 1 and top plate assembly 4. The anti-collision device is load-bearing by connecting the cable pile A and the lifting nose 7 via a chain 9. A tensioner 10 is also mounted on the chain 9 to adjust the length of the chain 9.

[0023] Specifically, in the present embodiment, there are a plurality of main body support tubes 3, which are arranged in a zigzag shape between the bottom plate 1 and the top plate assembly 4, and in order to strengthen the connection between the bottom plate 1 and the top plate assembly 4, a plurality of rows of main body support tubes 3 arranged in a zigzag shape are provided between the bottom plate 1 and the top plate assembly 4; in addition, in order to improve the supporting stability of the main body support tube 3, it can be considered that a reinforcing elbow plate 8 is also fixedly installed at the connection between the main body support tube 3 and the bottom plate 1 and the top plate assembly 4.

[0024] A reinforcing plate 2 is also fixedly installed on the bottom plate 1 to strengthen the strength of the bottom plate 1 and prevent the bottom plate 1 from being directly subjected to force. A plurality of connecting plates 6 are fixedly installed on the reinforcing plate. A plurality of baffles 5 are fixedly installed on the side of the bottom plate 1 facing away from the top plate assembly 4. The anti-collision device is clamped on the original fender through the baffle 5, and the connecting plate 6 is welded on the original fender B, so that the bottom plate 1 is in contact with the original fender.

[0025] In this embodiment, the anti-collision pad can be made of rubber and is fixed on the surface of the top plate assembly 4 by bolts 12.

[0026] The utility model is a lengthened fender tooling designed on the original fender of the dock, which increases the distance between the dock equipment and the lashing bridge after the ship is docked, and reduces the risk of collision between the dock crane and the ship lashing bridge; when used specifically, multiple anti-collision devices can be used at the same time according to the characteristics of each ship, and the ship needs to slowly approach the fender sideways and parallelly when in a moored state.

[0027] When installing the anti-collision device, the specific installation steps are as follows:

[0028] Step 1: Use a crane to transport the anti-collision device of the utility model to the original fender, and ensure that the baffle 5 is stuck on both sides of the original fender;

[0029] Step 2: Weld the connecting plate 6 to the original fender;

[0030] Step 3: Remove the crane;

[0031] Step 4, connecting the nose 7 on the anti-collision device and the mooring pile on the dock with a chain 9;

[0032] Step 5: adjust the tensioner 10 so that the chain 9 bears a certain force, thereby reducing the load of the anti-collision device on the original fender.

[0033] The utility model has a simple structure and is easy to operate: the baffle is clamped on the original fender, the connecting plate is welded to the original fender, the mooring pile and the lifting nose on the tooling are connected with a chain, and the chain length is adjusted by a tensioner to reduce the load on the original fender; the cost is low: ordinary materials can be used without special materials; the utility model has strong structural strength and high safety: after calculation, this device can be used for anti-collision when the ship is moored at the dock under a wind force 11.
