Furthermore, the revolute pair consists of a pin shaft, a bearing bush, a shaft spacer bush and a nut.
Further, the power source A and the power source B are hydraulic cylinders or electric cylinders.
The working process of the invention is roughly as follows: adopt the jack to connect between operation platform and body, make its navigation on water when expanding, the stability of navigation is good, packs up the back volume and diminishes, does benefit to and deposits and carries.
Compared with the prior art, the invention has the following advantages:
1. adopt the jack to connect between operation platform and body, can expand and fold, can improve the stability of surface of water navigation when making it expand, the size is littleer when folding, portable transportation and deposit.
2. The folding and unfolding device consists of symmetrical four-bar hinges, the kinematics of the folding and unfolding device accords with the conditions that the four-bar hinges have definite movement, and the folding and unfolding system can form a truss structure after being unfolded and has higher strength and rigidity.
3. Each component of whole hull can be dismantled, easy to assemble, debug, transportation and deposit. The operation platform is designed freely, and a user can modify the operation platform according to own requirements, so that the requirements of different application fields of the ship can be met.
