Description

Technical Field

[0001] This invention relates to the field of tools for ships or floating barges, and in particular to a ladder for boarding and alighting floating barges at docks. Background Technology

[0002] During the shipyard's production and construction process, barges are frequently moored at the dock. There are no dedicated ladders for personnel to get on and off the dock and barges. Previous common practices included:

[0003] 1. Sometimes climbing with bare hands is inconvenient and very dangerous;

[0004] 2. Temporary scaffolding with ladders was erected, but the ladders moved up and down with the tide, posing a safety hazard.

[0005] 3. Constructing a permanent dock ladder extending underwater would make it easy for barges to collide when berthing.

[0006] In addition, there is sometimes a certain distance between the ship and the elevator, which poses a safety hazard for people going up and down. Summary of the Invention

[0007] In view of the above-mentioned problems existing in the prior art, the present invention provides a simple, rotatable ladder for dock floating barges. It can rotate to different angles with the rise and fall of the tide to meet the needs of personnel going up and down for construction, and solves the technical problems such as the lack of ladders or mismatch between ladders at docks.

[0008] This invention provides a ladder for boarding and disembarking floating barges at a wharf, comprising:

[0009] A straight ladder body has a flat ladder section formed at its upper end, which is set at a set angle to the straight ladder body. The flat ladder section and the straight ladder body are reinforced and fixed by a support reinforcement member.

[0010] The railing is fixed to the bank by a base, and two adjacent railings are fixedly connected by a round tube shaft. The flat ladder is sleeved on the round tube shaft by a sleeve.

[0011] The straight ladder body has a round tube at one end away from the flat ladder section to prevent damage to the floating barge when the straight ladder body comes into contact with the floating barge;

[0012] When the straight ladder body is placed on the floating barge, the angle between the horizontal ladder section and the horizontal plane is not greater than a first set angle, and the straight ladder body floats with the floating barge. When no floating barge is docked, the straight ladder body is attached to the side wall of the shore or pulled to the shore by rotating the sleeve relative to the circular tube shaft.

[0013] In some embodiments of the present invention, the straight ladder body includes inclined ladder tubes and treads located between two inclined ladder tubes and arranged perpendicularly to the inclined ladder tubes.

[0014] In some embodiments of the present invention, the base is fixedly connected to the shore by expansion bolts.

[0015] In some embodiments of the present invention, the railing is provided with a pull ring to pull the ladder body by means of a pull rope threaded in the pull ring.

[0016] In some embodiments of the present invention, the length of the railing is not less than 1050mm, and it is made of a round tube with a diameter of not less than 40mm and a thickness of not less than 3mm.

[0017] In some embodiments of the present invention, the diameter of the circular tube shaft is 42 mm and the length is 1000 mm, and the diameter of the sleeve is 54 mm and the length is 200 mm.

[0018] In some embodiments of the present invention, the cylindrical shaft is provided with a limiting component for restricting the movement of the sleeve along the axial direction on the cylindrical shaft.

[0019] In some embodiments of the present invention, the base includes a base plate for fixed connection to the shoreline ground by expansion bolts, and a base tube disposed in the middle of the base plate and perpendicular to the base plate for mounting the railing, the base tube having a diameter of 60mm.

[0020] In some embodiments of the present invention, the support reinforcement is a triangular elbow plate.

[0021] In some embodiments of the present invention, the straight ladder body is provided with a plurality of steps arranged at equal intervals, and the distance between the circular tube provided at the end of the straight ladder body away from the flat ladder part and the nearest step is smaller than the distance between two adjacent steps.

[0022] Compared with existing technologies, the beneficial effects of the dockside floating barge access ladder provided in this embodiment of the invention are as follows: its tooling structure is simple and easy to operate, solving the technical problem of conventional dockside access ladders being affected by tides, and its field use effect is good; moreover, it can rise and fall with the tide, and the straight ladder can rotate around the sleeve, solving the problem of conventional fixed frames being unable to move; at the same time, the bottom of the straight ladder is designed in the form of a round tube, so that it will not damage the paint on the barge when sliding; when the floating barge is not docked, the straight ladder can be rotated 90 degrees and placed on the shore, and when the floating barge is docked and personnel need to get on and off, the ladder can be rotated and placed on the barge, which is simple and convenient; when the dock needs to be moored, the entire ladder assembly can be temporarily removed from the base sleeve; in addition, the pull ring on the column can be used for the connection of the dockside guardrail chain, so as to provide water protection.
