[0003] In the prior art, it is usually necessary to use manpower and auxiliary tools to pull the vertical rocker arm back to the horizontal state before launching. The usual method is to apply external force to the upturned end of the rocker arm with a crane or a weight to push the rocker arm. Flip occurs, the operation process is complicated, consumes more operation resources, and has certain potential safety hazards

Embodiment 1
[0027] The self-turning and reset rocker launching method of this embodiment includes the following steps:
[0028] 1) if figure 1 As shown, the rocker arm 1 is rotatably connected to the stern of the launching barge 4 through the rotating shaft 2 and the semi-circular sleeve 3 used in conjunction with each other. The rotating shaft 2 is arranged on the rocking arm 1, and the semi-circular sleeve 3 is arranged on the launching barge 4. 2 is limited on the semi-circular sleeve 3, the rocker arm 1 can rotate around the rotating shaft 2, one end of the rocker arm 1 abuts against the slideway 6 for conveying the jacket 5, and the lower part of the launching barge 4 is provided for limiting The limiting device 7 for the further turning of the rocker arm 1 .
[0029] 2) The jacket 5 slides along the slideway 6 to the upper part of the rocker arm 1 and continues to slide forward. Under the action of the gravity of the jacket 5 and the gravity of the rocker arm 1 itself, the rocker a...

The invention relates to the technical field of ship devices, in particular to a self-turning return rocker arm launching operation method. After the rocker arm is turned to finish launching operation and a jacket leaves the rocker arm to fall into the water, the rocker arm is automatically turned and returns to a horizontal state before the launching operation under effects of stern trimming restoring moment of a launching barge, the buoyancy moment of the water and weight moment of the rocker arm. As the rocker arm can automatically return to the original state without external force applied to the rocker arm and without external construction conditions, the self-turning return rocker arm launching operation method, provided by the invention, is advantaged in that the method is simple and convenient to operate, the efficiency is high and the cost is saved.
Description
technical field [0001] The invention relates to the technical field of marine devices, in particular to a method for launching a self-turning and reset rocker arm. Background technique [0002] The rocker arm of the launching barge is a key system on the launching barge. It is the main load-bearing system and force-bearing system of the jacket and other equipment during the launching process. , when the jacket slides along the launching barge track to the stern of the launching barge, the rocker arm rotates along the rotating shaft under the reaction force acting on the jacket when the jacket is launched, the buoyancy moment of the water on the rocker arm and its own weight, and the jacket jacket is turned over together Prompt the jacket to be launched, and finally the jacket leaves the barge and falls into the water, and the rocker arm is erected at the tail of the launching barge. One-time launching operation. [0003] In the prior art, it is usually necessary to use man...
