Description

Technical Field

[0001] The utility model relates to the technical field of cross-ship ladders, in particular to a special cross-ship ladder for ships. Background Art

[0002] Ships docked at existing docks can only dock together with ships at outer docks by wrapping cables around mooring bollards. Due to the inconsistent freeboard heights of various ships, when multiple ships are docked together and personnel on board need to transfer across ships (move positions), it is usually necessary for the crew to throw cables and wrap them around mooring bollards to limit the displacement of the two ships. Personnel need to climb over the railings of each ship. The freeboard height difference of some ships exceeds 2m, and the horizontal spacing of the outer chords of the ships is about 80mm (the distance is larger when the cables are relaxed). On the one hand, personnel are prone to falling from a height during the crossing process, and falling into the water into the gap between the two ships can easily cause serious injuries to people being squeezed by the two ships. On the other hand, personnel cannot cross from the lower ship to the higher ship.

[0003] CN218751270U discloses a combined ladder for transferring personnel across ships at sea, including a vertical ladder and an inclined ladder. Ships are usually accompanied by shaking, and it is difficult for personnel to move from the vertical ladder to the inclined ladder. In addition, when there is a certain height difference between the two ships, the combined ladder is not very suitable.

[0004] Therefore, a special cross-ship ladder is needed for safely transferring personnel across the ship. Utility Model Content

[0005] In view of the above problems, the utility model provides a ship-specific cross-ship ladder, in which the ladder surface angle can be adjusted, and the horizontal angles of the long inclined ladder and the short inclined ladder pedals can be adjusted. It can meet the cross-ship needs between most ships with different freeboard heights and can effectively ensure the safety of the cross-ship ladder when in use.

[0006] Specifically, the utility model provides a special cross-ship ladder for ships, comprising:

[0007] A long inclined ladder, configured with an adjustable inclination angle;

[0008] A short inclined ladder, configured with an adjustable inclination angle;

[0009] A connecting platform is horizontally arranged between the long inclined ladder and the short inclined ladder, and is respectively connected to the upper ends of the long inclined ladder and the short inclined ladder to connect the long inclined ladder and the short inclined ladder;

[0010] The long inclined ladder, the short inclined ladder and the connecting platform are all provided with handrails, and the long inclined ladder and the short inclined ladder are all provided with pedals, and the pedals are configured to be adjustable in horizontal angle.

[0011] Furthermore, the long inclined ladder and the short inclined ladder are both connected to the connecting platform via a rotating shaft, and angle adjusters are provided at the connections with the connecting platform, and the angle adjusters are used to adjust the inclination angle of the long inclined ladder or the short inclined ladder.

[0012] Furthermore, the angle adjuster comprises:

[0013] A first adjustment plate is mounted on the end of the connecting platform through a fixing bracket, and a plurality of arc-shaped first adjustment holes are provided on its outer edge; the rotating shaft passes through the connecting platform, the fixing bracket and the first adjustment plate and is connected to the long inclined ladder or the short inclined ladder;

[0014] The first limiting bolt passes through the first adjusting hole and is connected to the long inclined ladder or the short inclined ladder, and is used to fix the inclination angle of the long inclined ladder or the short inclined ladder.

[0015] Furthermore, both the long inclined ladder and the short inclined ladder are provided with a pedal adjustment mechanism, and the pedal is connected to the long inclined ladder or the short inclined ladder through a connecting shaft.

[0016] Furthermore, the pedal adjustment mechanism includes two groups of connecting rod mechanisms distributed on both sides of the pedal, and each group of the connecting rod mechanisms includes:

[0017] A second adjustment plate is provided on the long inclined ladder or the short inclined ladder, and a plurality of arc-shaped second adjustment holes are provided on its outer edge;

[0018] A connecting rod is arranged along the long inclined ladder or the short inclined ladder and connected to the pedal;

[0019] The adjusting rod is connected to the second adjusting disk and the connecting rod respectively, and the connection point with the second adjusting disk is a fulcrum. The adjusting rod rotates around the fulcrum to drive the connecting rod to move, thereby driving the pedal to rotate around the connecting shaft;

[0020] The second limiting bolt passes through the second adjusting hole and is connected to the adjusting rod, and is used for fixing the horizontal angle of the pedal.

[0021] Furthermore, universal wheels are provided at the bottom ends of the long inclined ladder and the short inclined ladder.

[0022] Furthermore, the universal wheel is a height-adjustable universal wheel. When the universal wheel is in a low position, it contacts the ship's deck; when the universal wheel is in a high position, it is out of contact with the ship's deck, and the bottom ends of the long inclined ladder and the short inclined ladder contact the ship's deck.

[0023] Working principle:

[0024] First, adjust the telescopic stroke of the universal wheel. After the universal wheel touches the ground, the entire cross-ship ladder is supported and its base is suspended in the air, so that the cross-ship ladder can be moved. After the cross-ship ladder is moved to a suitable position, loosen the first limit bolt, rotate the long inclined ladder and the short inclined ladder according to the freeboard height of the two ships, and adjust their inclination angles to adapt to the freeboard height of the two ships. After adjustment, tighten the first limit bolt to limit the long inclined ladder and the short inclined ladder to prevent them from rotating.

[0025] Then loosen the second limit bolt, and use the lever principle to move the connecting rod by bending the adjustment rods on both sides, and then drive the pedal to rotate around the connecting shaft until the pedal is adjusted to be parallel to the horizontal plane, and then tighten the second limit bolt, and then the personnel can be transferred. When the cross-ship ladder needs to be used in a fixed position for a long time, the universal wheel can be adjusted to shrink its stroke, so that the long and short inclined ladder bases of the cross-ship ladder are supported on the deck, so that personnel can be transferred smoothly across the ship.

[0026] Compared with the prior art, the utility model has the following beneficial effects:

[0027] (1) The special ship-crossing ladder provided by the utility model has adjustable angles of the long and short inclined ladders, which can be installed and used between ships with different freeboard heights.

[0028] (2) The angles of the steps of the long inclined ladder and the short inclined ladder to the horizontal plane are adjustable, so that the steps can be kept parallel to the horizontal plane, thereby ensuring the safety of the cross-ship ladder when in use. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0037] The present invention is further described in detail below through specific implementation modes in conjunction with the accompanying drawings.

[0038] Example 1

[0039] like Figure 1-2 As shown, this embodiment provides a special cross-ship ladder for ships, including: a long inclined ladder 1, a short inclined ladder 2 and a connecting platform 3. The long inclined ladder 1 and the short inclined ladder 2 are connected into a whole through the connecting platform 3, and the length difference between the long inclined ladder 1 and the short inclined ladder 2 is used to make up for the height difference of the ship's freeboard. Specifically, the long inclined ladder 1 and the short inclined ladder 2 are mainly composed of side panels, pedals 7 and handrails 4. The connecting platform 3 is provided with handrails 4, and the top of the side panel is connected to the connecting platform 3. Through this cross-ship ladder, personnel can be transferred across the ship. The outer side of the side panels of the long inclined ladder 1 and the short inclined ladder 2 are provided with height-adjustable universal wheels 8. It should be noted that the height-adjustable universal wheels 8 are prior art, such as the height-adjustable universal wheels disclosed in patents such as CN213322506U and CN205736665U. The specific structure will not be repeated here. When the universal wheel 8 is adjusted to a low position, the bottom of the long inclined ladder 1 and the short inclined ladder 2 are suspended in the air, and the universal wheel 8 is in contact with the deck, so that the cross-ship ladder can be moved. When the cross-ship ladder needs to be used in a fixed position for a long time, the universal wheel 8 is adjusted to a high position, so that it is out of contact with the deck, and the bottom of the side panels of the long inclined ladder 1 and the short inclined ladder 2 are supported on the deck of the ship as supporting parts to ensure the stability of the cross-ship ladder. The bottom of the side panel is provided with an anti-skid rubber block to prevent the deck paint from being scratched when the ship shakes, and at the same time increase the friction between the base and the deck, so that personnel can smoothly transfer across the ship.

[0040] like Figure 3-4As shown, the long inclined ladder 1 and the short inclined ladder 2 are connected to the connecting platform 3 through a rotating shaft 55, and an angle adjuster 5 is provided at the connection with the connecting platform 3. The angle adjuster 5 includes: a first adjusting disk 51, a fixing bracket 54 and a first limiting bolt 53. The first adjusting disk 51 is semicircular as a whole, and its arc side is away from the connecting platform 3. The first adjusting disk 51 is installed at the end of the connecting platform 3 through the fixing bracket 54, and a plurality of first adjusting holes 52 are provided on its outer edge. The top of the fixing bracket 54 is connected to the first limiting bolt 53 at the top by bolts. The adjusting hole 52 is connected, and the rotating shaft 55 passes through the connecting platform 3, the fixed bracket 54 and the first adjusting disk 51 and is connected to the side plate of the long inclined ladder 1 or the short inclined ladder 2, so that the long inclined ladder 1 or the short inclined ladder 2 can rotate around the rotating shaft 55. After rotating to a suitable angle, the first limiting bolt 53 passes through the corresponding first adjusting hole 52 and is connected to the side plate of the long inclined ladder 1 or the short inclined ladder 2. The first limiting bolt 53 is used to lock the long inclined ladder 1 / short inclined ladder 2 with the first adjusting disk 51, thereby limiting the rotation of the long inclined ladder 1 / short inclined ladder 2.

[0041] Furthermore, if Figure 5-6 As shown, a pedal adjustment mechanism 6 is provided on the long inclined ladder 1 and the short inclined ladder 2. The pedal adjustment mechanism 6 includes two groups of connecting rod mechanisms distributed on both sides of the pedal 7. Each group of connecting rod mechanisms includes: a second adjusting disk 61, a connecting rod 64 and an adjusting rod 63. The second adjusting disk 61 is welded to the inner side of the side plate of the long inclined ladder 1 / short inclined ladder 2. Its upper part is arc-shaped, and the outer edge is provided with a plurality of arc-shaped second adjusting holes 62. The connecting rod 64 is arranged along the long inclined ladder 1 / short inclined ladder 2. The pedal 7 is connected to the connecting rod 64. The middle part of the adjusting rod 63 is connected to the second adjusting disk 61 as a fulcrum. The adjusting rod 63 extends from one end away from the connecting rod 64 as a handle. At the same time, the handles on both sides are forced to move, which can drive the connecting rod 64 to move, and then drive the pedal 7 to rotate around the connecting shaft 66. After adjusting to a suitable angle, a second limiting bolt 65 is used to pass through the second adjusting hole 65 at the corresponding position and then connected to the adjusting rod 63 to fix the pedal 7. The angles of the steps 7 of the long inclined ladder 1 and the short inclined ladder 2 with respect to the horizontal plane can be adjusted by utilizing the lever principle, so as to adapt to the setting up of cross-ship ladders between ships with different freeboard heights. The steps 7 of the inclined ladder can be adjusted to be parallel to the horizontal plane, so as to improve the convenience and safety of personnel transfer across ships.
