Abstract
The utility model discloses an upper structure of harbor boarding ladder comprising a lower platform plate overlapped on the outside of the hull deck. The bottom of the lower platform plate is supported by a diagonal brace part, and an upper platform plate is disposed above the lower platform plate, besides, bolts are connected between the upper and lower platform plate. The bottom of the upper platform plate is provided with a circular marble disc web plate, in which is disposed a marble disc, and pallets are fixedly disposed on two sides of the upper platform plate. The utility model has advantages of small occupation area, ability of maintaining the vertical stability, and applicability in the elevating change of ships and in the variable conditions of ships, which is near or far from the shore, caused by the tightness of cables.
Description
Technical field:
The utility model relates generally to the harbour boarding ladder, relates in particular to the topside of harbour boarding ladder.
Background technology:
Present shipyard roustabout construction operation personnel boarding ladder up and down, its design all is broadly divided into two kinds.A kind of is the rectangular bar of steel structure boarding ladder that vertically spirals up, and the shortcoming of this type of boarding ladder is for keeping stable, and floor area is bigger.Do not allow excessively as floor area,, needs constantly to regulate interface channel platform between (dress welds) ladder and the boat deck, loaded down with trivial details relatively inconvenience because of fluctuation in stage simultaneously then owing to manifesting to a certain degree unstability highly too greatly and rocking.Another kind of long steel inclined ladder for action roller under having and last articulating device, but because ship and floor level difference are too big, cause inclined ladder oversize, the angle of marking time simultaneously can not adapt to the variation of inclined ladder lifting, and oversize inclined ladder has a strong impact on the current of wharf crane and power actuated vehicle.
The utility model content:
The utility model purpose is exactly in order to remedy the defective of prior art, a kind of topside of harbour boarding ladder is provided, both floor area was not too big, the boarding ladder that can keep vertical stability again, suitable boats and ships oscilaltion variation of prior energy and boats and ships are because the far away or near state of offshore within the specific limits that the hawser degree of tightness occurs.
The utility model is achieved through the following technical solutions:
The topside of harbour boarding ladder, include the lower platform plate that is overlapped on the deck in ship structure outside, lower platform plate bottom is supported by bracing element, the top of lower platform plate is provided with the upper mounting plate plate, be connected with bolt between upper mounting plate plate and the lower platform plate, the bottom of upper mounting plate plate is provided with the wheel ball bearing web of annular arrangement, is placed with wheel ball bearing in the wheel ball bearing web, and the both sides of upper mounting plate plate are installed with clamp.
The utility model has the advantages that:
The epimere of harbour boarding ladder is a ramp, have three bulks, connect by active pin and otic placode between three, adapt to the variation of boats and ships offshore distance and the variation of lifting, every bulk of two major parts is designed to go up the rotatable platform that lower rotary table is formed by two up and down; Last combined moving flat-bed lower rotary table can simply be welded on the ship deck edge; Following combined moving flat-bed lower rotary table is placed on the hypomere fixed type steel structure inclined ladder platform slideway.In addition, have and change terraced on long steel inclined ladder upper end that curve marks time and the last combined moving flat-bed and be connected by the bolt otic placode; Its inclined ladder lower end also is connected by the bolt otic placode with following combined moving flat-bed top rotary table.The personnel that go on board all felt safe, comfortable when its curvature line style of marking time can adapt to the variation of inclined ladder angle.
Description of drawings:
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is a birds-eye view of the present utility model.
The specific embodiment:
Referring to accompanying drawing, the topside of harbour boarding ladder, include the lower platform plate 2 that is overlapped on deck in ship structure 1 outside, lower platform plate 2 bottoms are supported by bracing element 3, the top of lower platform plate 2 is provided with upper mounting plate plate 4, is connected with bolt 5 between upper mounting plate plate 4 and the lower platform plate 2, and the bottom of upper mounting plate plate 4 is provided with the wheel ball bearing web 6 of annular arrangement, be placed with wheel ball bearing 7 in the wheel ball bearing web 6, the both sides of upper mounting plate plate 2 are installed with clamp 8.
