Description
Technical field:
The utility model relates generally to the hierarchic structure of boarding ladder
Background technology:
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 hierarchic structure of boarding ladder to be provided, and the intensity of ladder is reliable, and is easily manufactured, good stability, and the personnel that go on board all feel safe, comfortable in the time of adapting to the inclined ladder angle and change.
The utility model is achieved through the following technical solutions:
The hierarchic structure of boarding ladder includes left and right railing, and stair-stepping pedal is installed between the left and right railing, and the corner of pedal is circular-arc, and the two ends of left and right railing are fixedly connected with the connection bracket respectively, connects on the bracket to have connection holes.
Has the triangle projection on the described pedal.
The utility model has the advantages that:
The utility model has to be changeed terraced on long steel inclined ladder upper end that curve marks time and the last combined moving flat-bed and is 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 an A-A cutaway view of the present utility model.
The specific embodiment:
Referring to accompanying drawing, the hierarchic structure of boarding ladder, include left and right railing 1,2, stair-stepping pedal 3 is installed between the left and right railing, have triangle projection 4 on the pedal 3, it is circular-arc 5 that the corner of pedal is, and the two ends of left and right railing are fixedly connected with respectively and connect bracket 6, have connection holes on the connection bracket 6, the connection bracket of lower end is fixedly connected with travelling car 7.
