Description

Technical Field

[0001] The utility model belongs to the technical field of ship climbing ladders, and in particular relates to a ship climbing ladder structure. Background Art

[0002] A ship is a means of transport that can sail or anchor in waters for transportation or operations. A ship climbing ladder consists of a ladder body and a mounting base. The ladder is fixed to the surface of the ship through the mounting base to facilitate the crew to climb on the ship through the ladder.

[0003] When the existing ship climbing ladder is used on a ship, it is fixed on the ship with a mounting seat to facilitate the crew to climb, but it has the following defects:

[0004] (1) The existing ship climbing ladder is vertically installed on the ship body. When the crew members climb, their feet step on the ladder. When climbing, the feet will exert an inward squeezing effect and vibration on the ladder. The squeezing effect will directly act on the surface of the ship, which is easy to cause damage to the surface of the ship. For this reason, we propose a ship climbing ladder structure.

[0007] Preferably, a limiting groove is provided on the side wall of the connecting column, a limiting block is arranged inside the limiting groove, and the limiting block is fixed on the inner wall of the supporting cylinder seat.

[0008] Preferably, a threaded hole is formed on the end surface of the support cylinder seat, a threaded column is threadedly connected to the inside of the threaded hole, a movable plate is provided between the threaded column and the spring, and the movable plate is provided inside the support cylinder seat.

[0009] Preferably, a screwing groove is formed on one end surface of the threaded column, and the cross-section of the screwing groove is a hexagonal structure.

[0010] Preferably, a ball groove is formed at the other end of the threaded column, and a ball is embedded in the ball groove.

[0011] Preferably, the connection column and the surface of the straight ladder body are connected with a rib plate, and the longitudinal section of the rib plate is a triangular structure.

[0012] Preferably, the longitudinal sections of the connecting column and the supporting cylinder seat are both circular structures, and the cross-section of the supporting cylinder seat is a T-shaped structure.

[0013] Compared with the prior art, the beneficial effects of the utility model are:

[0014] (1) Through the designed connecting column, spring and support cylinder seat, the support cylinder seat equipped with the spring is movably installed on the ladder body through the connecting column, and the ladder body is fixed to the hull through the support cylinder seat. When climbing, the ladder is squeezed inward by the climbing action. At this time, the connecting column moves in the support cylinder seat and squeezes the spring at the same time, so that the squeezing and vibration effect caused by climbing can be achieved to achieve buffering and shock absorption, effectively reducing the damage to the ship when climbing the ladder. Through the designed limit groove and limit block, the sliding of the support cylinder seat is limited to prevent the support cylinder seat from falling off the connecting column. Through the designed threaded hole, threaded column and movable plate, the thread of the threaded column is screwed, and the movable plate is squeezed to adjust its position in the support cylinder seat, so as to change the initial compression degree of the spring to achieve elastic adjustment and achieve the best buffering and shock absorption effect. Through the designed ball bearing, the lubricity of the threaded column surface is increased to reduce the wear on the movable plate surface. BRIEF DESCRIPTION OF THE DRAWINGS
