Description

An aircraft carrier mooring device

technical field

The utility model relates to a mooring device, in particular to an aircraft carrier mooring device.

Background technique

HB6373 published type III type B mooring ring assembly, its basic structure is composed of rings and joints. The rings are welded by argon arc welding and mounted on a joint with a retaining ring and threaded on the other end of the joint, with a single point connection mounted on the aircraft floor reinforcement. There are four disadvantages of this structure. One is that the lifting ring is made of welding technology, the internal force flow line of the welded part is discontinuous, the strength of the weld is weak, and the reliability is not high when the large load is moored. The second is that the lifting ring and the joint are hinged, and the joint and the aircraft floor are connected by only one bolt, so it can only bear the load in one direction, and the load in other directions may cause the joint to loosen, and the reliability is not high. The third is that its anti-fatigue is insufficient. Fourth, because the joint is directly connected to the floor, it is easy to cause direct damage to the aircraft body when the large load is moored in complex working conditions.

Contents of the invention

The purpose of this utility model: to provide a mooring device to improve the reliability and fatigue life of the mooring device when it is moored with a large load

The technical scheme of the present utility model: an aircraft carrier mooring device, characterized in that: the mooring device includes a mooring ring body 1, a suspension ring 2, a bolt 3 and a mooring ring body joint 4, and the mooring ring body The middle part of the joint 4 is arched, and the suspension ring 2 is located in the arched hole;

One end of the mooring ring body joint 4 and the mooring ring body 1 are provided with bolt holes, above the bolt holes on the mooring ring body joint 4, a groove matching the head of the bolt 3 is provided, and the mooring ring body joint 4 is fixed together with the mooring ring body 1 by bolts 3.

As an improvement of the technical solution, one end of the mooring ring body joint 4 is provided with a flanging matched with the mooring ring body 1 . This design can improve the fixing reliability of the mooring ring body joint 4 and the mooring ring body 1 .

Beneficial effects: Compared with the traditional scheme, the utility model has the following advantages: firstly, die forging is used to manufacture all parts, which has excellent mechanical properties, high safety and reliability; Can bear load in one direction. The suspension ring of the utility model has a high degree of freedom of movement. The mooring lateral load is finally decomposed into axial loads in the three directions of X, Y, and Z, and finally transmitted to the aircraft floor without causing damage to the mooring joint. Loose, high reliability; third, the tapered bolts and nuts are all MJ threads, excellent fatigue resistance; fourth, the mooring joint is not directly connected to the floor, but is connected to the aircraft floor through a box-shaped mooring ring, and the connecting bolts The number is large, the section is large, the stress at the joint is low, and even if the mooring ring is damaged under complex working conditions, the aircraft floor is still intact; the fifth is to use conical head bolts. During construction, the head of the bolt is directly locked on the mooring ring In the groove of body joint 4, it is convenient to install.

In the figure: 1 is the mooring ring body, 2 is the suspension ring, 3 is the bolt, and 4 is the mooring ring body joint.

Detailed ways

The technical solution will be described in further detail below in conjunction with the accompanying drawings.

As shown in FIG. 1 , one end of the mooring ring joint 4 is provided with a bolt hole, a groove is provided above the bolt hole, and a bridge-shaped hole is provided in the middle, and the bridge-shaped hole passes through one end of the suspension ring 2 . The tapered head bolt 3 connects the mooring ring body joint 4 with the box-shaped mooring ring body 1 through the bolt hole on the mooring ring body joint 4 . The whole mooring ring assembly is then connected to the aircraft floor at multiple points with bolts through the box-shaped mooring ring body 1 .

The mooring ring body joint 4 is fixed by three bolts, specifically, one end of the mooring ring body joint 4 is connected to the box-shaped mooring ring body 1 by a tapered bolt 3, and the other end is connected to the aircraft floor by two bolts That is to say, the suspension ring 2 and the mooring joint 4 are indirectly connected to the aircraft floor through the box-shaped mooring ring body 1, which can not only reduce the stress but also reduce the influence of the mooring accident on the aircraft floor.

The suspension ring 2 passes through the bridge-shaped hole in the middle part of the mooring ring body joint 4, the connection degree of freedom is high, and lateral load is allowed. The torque of the mooring side load acts on the mooring joint, and the tapered bolts will not loosen, which has high reliability.

The tapered bolts 3 and nuts all adopt MJ thread, which has excellent anti-fatigue effect. The head of the bolt 3 is tapered, and it is stuck in the groove of the mooring ring joint 4 during installation, which is convenient for installation.
