Accommodation ladder moving device

Abstract

The invention discloses an accommodation ladder moving device. The accommodation ladder moving device comprises a sliding rail, a connecting device and a sliding rail groove, wherein the sliding rail is fixed on the side edge of a wharf or the side edge of a wharf access ladder, the connecting device is connected with an accommodation ladder, the sliding groove is formed in one end of the connecting device, the sliding rail is sleeved with the sliding rail groove, and a plurality of idler wheels are arranged between the sliding rail groove and the sliding rail. According to the accommodation ladder moving device, the sliding rail groove moves along the sliding rail, so that the accommodation ladder horizontally moves along the edge of the wharf. In addition, the sliding wheels are arranged between the sliding rail and the sliding rail groove, and therefore the friction produced when the sliding rail groove moves is reduced.

Description

technical field [0001] The invention relates to the field of shipbuilding, in particular to a gangway moving device for movably connecting a gangway to a wharf or a wharf stair. Background technique [0002] At present, the pier boarding ladders used in the field of shipbuilding and repair are generally connected to the hull, the pier, and the pier boarding ladder by welding, so that the welding part must be cut whenever the ship leaves the pier, thus increasing the grinding and The amount of paint work. In addition, when it is close to the pier again, it has to be re-welded again, which increases the unnecessary workload, takes time, labor and materials. [0003] In addition, with the fluctuation and fluctuation of the water surface, the height of the hull and the distance between the hull and the dock often change. At this time, the boarding ladder of the same specification cannot meet the needs of various situations. In other words, it must be It can only be applied by ...

Problems solved by technology

[0002] Currently, the wharf boarding ladder used in the field of shipbuilding and repair is generally connected with the hull, the wharf, and the wharf boarding ladder by welding, so that the welding part must be cut every time the ship leaves the wharf, thus increasing the grinding, the amount of paint work

In addition, when it is close to the dock again, it has to be re-welded, which increases unnecessary workload, time-consuming, laborious, and material-intensive

[0003] In addition, with the fluctuations and fluctuations of the water surface, the height of the hull and the distance between the hull and the dock often change. At this time, the boarding ladder with the same specification cannot meet the needs of various situations. In other words, it must It is only applicable to move the hull and equip multiple boarding ladders of different specifications, which increases the cost and is time-consuming, labor-intensive and expensive
