Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of dock ship gangway protection, in particular to a dock ship gangway suitable for large tidal range. Background Art
[0002] In offshore platform loading operations and ship transportation businesses, access facilities between the dock and the ship's site are essential, and are used exclusively for loading and unloading cargo, boarding and disembarking passengers, or for construction site traffic.
[0003] Currently, gangways are typically installed directly on docks. If the ship's deck is higher than the dock, the gangway is fixed to the ship. If the ship's deck is lower than the dock, a ladder is installed at the rear of the gangway for auxiliary use. Because ships typically don't adjust their draft during operations, this method of use is limited to short periods of time. If the gangway is used for extended periods and the tide heights vary significantly, the ladder will need to be re-installed multiple times, adjusting its angle. Utility Model Content
[0004] The purpose of the utility model is to overcome the shortcomings of the existing technology and provide a dock ship gangway ladder suitable for large tidal ranges. The gangway ladder can be adjusted with the tide and the height change of the main deck of the ship. It can be used for a long time without the need to make multiple adjustments to the ladder used.
[0005] In order to solve the above technical problems, the present invention provides the following technical solutions: a gangway for dock ships with large tidal range, comprising a gangway body, a support mechanism provided on one side of the gangway body for supporting the gangway, a hook assembly at one end of the gangway body, and a roller assembly at the other side, wherein the hook assembly is suspended on the support mechanism.
[0006] The support mechanism comprises a support frame, a hanging rod arranged on the support frame, and the hook assembly is arranged on the hanging rod and is rotatably connected to the hanging rod.
[0007] Furthermore, the support frame includes two herringbone frames, and the hanging rod is rotatably arranged between the two herringbone frames.
[0008] Furthermore, the hook assembly is provided with two groups, which are respectively arranged on both sides of one end of the gangway main body, including a hook plate, one side of the hook plate is provided with a U-shaped opening, and the arc-shaped inner side of the U-shaped opening is provided with a rubber pad.
[0009] Furthermore, the radius of the arc of the U-shaped opening is slightly larger than the radius of the hanging rod.
[0010] Furthermore, the roller assembly includes a roller and a rotating shaft connected between the roller and the gangway body.
[0011] Furthermore, the gangway main body is also provided with a lifting lug.
[0012] Furthermore, the support frame is fixedly connected to the ship.
[0013] Compared with the prior art, the beneficial effects of the present invention are:
[0014] The hook assembly of the utility model is used in conjunction with the supporting mechanism, and its angle can be changed as the draft of the ship increases or decreases. It can be used for a long time at a certain height difference between the main deck of the ship and the dock, greatly reducing the manpower and time wasted in adjusting the gangway and improving efficiency.

[0023] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments; based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.
[0024] Example 1:
[0025] like Figure 1-5As shown, a gangway suitable for dock ship connection with large tidal range includes a gangway main body 4, a support mechanism 5 provided on one side of the gangway main body 4 for supporting the gangway, a hook assembly 1 is provided at one end of the gangway main body 4, and a roller assembly 2 is provided at the other side, the hook assembly 1 is suspended on the support mechanism, and the gangway main body 4 is also provided with a lifting lug 3, the lifting lug 3 is used to lift the gangway for lifting and transportation.
[0026] The hook assembly 1 is provided with two groups, which are respectively provided on both sides of one end of the gangway body 4, including a hook plate 11, one side of the hook plate 11 is provided with a U-shaped opening 12, and the arc inner side of the U-shaped opening 12 is provided with a rubber pad 13.
[0027] The roller assembly 2 includes a roller 21 and a rotating shaft 22 connected between the roller 21 and the gangway main body 4, so that the roller 21 is rotatably connected to the gangway.
[0028] The support mechanism includes a support frame and a hanging rod 51 mounted on the support frame. The support frame is fixedly connected to the vessel. The hook assembly 1 is mounted on the hanging rod 51 and is rotatably connected to the hanging rod 51. The support frame includes two herringbone brackets 52, and the hanging rod 51 is rotatably mounted between the two herringbone brackets 52. The radius of the arc of the U-shaped opening 12 of the hook plate 11 is slightly larger than the radius of the hanging rod 51, facilitating the hanging of the hook assembly 1 on the hanging rod 51.
