Detailed description of the invention
The rotary boarding ladder using method of the utility model, as shown in Figure 1, Figure 2, Figure 3, Figure 4:
The first step: according to the tidal range situation of the distance between harbour and ship side and harbour, determine the length in aisle 1, the height of setting support post 2 and ladder 3.
The overproof of certain place harbour is high tide level+2m, low tide level (LWL)-3m, and the distance between harbour and ship side is 1m, and the length in design aisle 1 is 12m, width is 0.6m, and the height of support post 2 is 1.14m, and the height of ladder 3 is 1.14m.
Second step: be connected with support post 2 with ladder 3 respectively by bearing pin 4 at the two ends in aisle 1, so that ladder 3 can rotate along with tidal range, automatically regulates ladder and the angle between aisle 1 and support post 2, meets the operation of going on board under different sea situation.
3rd step: the support post 2 be connected with one end, aisle 1 and ladder 3 are placed on distance at least 3m place, bank, wharf apron, and the support post 2 be connected with aisle 1 other end and ladder 3 are placed on ship deck; Aisle connects harbour and boats and ships between two support posts.
4th step: when ship deck B is higher than harbour bank A, the aisle 1 being positioned at A side, harbour bank is rotated up relative to harbour bank by the bearing pin 4 on this side support post 2; Be rotated down relative to ship deck by the bearing pin 4 on this side support post 2 in the aisle 1 being positioned at ship deck B side, the aisle being in level before making it is inclined, constructability operating personnel at upper and lower boats and ships at the incoming tide, as shown in Figure 3;
When ship deck B is lower than harbour bank A, the aisle 1 being located at A side, harbour bank is rotated down relative to harbour bank by the bearing pin 4 on this side support post 2; The aisle 1 being positioned at ship deck B side is rotated up relative to ship deck by the bearing pin 4 on this side support post 2, the aisle of level is in before making it, inclined after over-rotation, constructability operating personnel is upper and lower boats and ships when ebb tide, as shown in Figure 4.
5th step: handling construction operation personnel and crewman, by being placed on the ladder 3 of A side, harbour bank, arriving the ladder 3 being placed on ship deck B side, climb up boats and ships afterwards via aisle 1; Otherwise handling construction operation personnel and crewman, by being placed on the ladder 3 of ship deck B side, arriving the ladder 3 being placed on harbour bank A, can go ashore via aisle 1.
