Description

Technical Field

[0001] The invention relates to the technical field of marine equipment, and in particular to a flip-type Panama Canal platform. Background Art

[0002] The Panama Canal, like the Suez Canal, was built along the isthmus. The so-called isthmus is a narrow strip of land connecting two larger pieces of land, similar to a strait, which is equivalent to the land sandwiched between two seas. The Panama Canal was built on the Isthmus of Panama. As a golden waterway connecting the Pacific and Atlantic Oceans, with the development of the global economy, the world trade activities and the substantial increase in cargo volume have led to the emergence of more and more large ships. Since the locks of the Panama Canal are only 33.53 meters wide and 12.55 meters deep, Panamax ships can only pass through almost close to the wall. Therefore, the traditional observation tower around the cab cannot observe the distance between the lower part of the ship's side and the lock. Therefore, Panamax ships usually have an observation platform extending out of the hull on the side of the observation tower around the cab. Under normal circumstances, the Panama Canal observation platform is designed as a fixed platform, which needs to be fixed on both sides of the cab for use. This design is not suitable for 26,000-ton Great Lakes self-unloading ships that pass through the Panama Canal. The observation platform on the side is useless after crossing the Panama Canal. The fixed observation platform on the side not only affects the appearance of the hull, but also increases the total width of the hull. In view of the above, we propose a flip-type Panama Canal platform to solve the above problems. Summary of the invention

[0003] The purpose of the present invention is to solve the above technical problems and to provide a flip-type Panama Canal platform which can be unfolded when passing through the Panama Canal locks to facilitate observation of the distance between the hull side and the locks for navigation and observation, and can be flipped and folded after passing through the Panama Canal without affecting the overall width of the hull appearance.

[0004] In order to achieve the above-mentioned purpose, the present invention adopts the following technical scheme: a flip-type Panama Canal platform, including a cab, a lookout tower is arranged outside the cab, a fixed fence is arranged outside the lookout tower, and the lookout towers on both sides are provided with an observation platform structure that can be flipped open and extended to the outside of the lookout tower, the observation platform structure includes a flip plate located at the bottom, and observation platform fences are arranged on three sides of the flip plate; at least one triangular support frame is also arranged at the bottom of the observation platform structure, one right-angle side of the triangular support frame is connected to the lookout tower, and the other side is connected to the bottom of the flip plate to form a stable support for the observation platform structure.

[0005] Furthermore, a hinged ear seat is fixedly provided on the observation deck, one side of the flip plate is hingedly connected to the hinged ear seat, and the observation deck fences on three sides have columns vertically fixed on the flip plate, and cross bars are horizontally connected between the columns.

[0006] Furthermore, the bottom of the hinged ear seat is fixed to the bottom surface of the observation tower by a plurality of bolts.

[0007] Furthermore, the triangular support frame is a diagonal bracing beam, which forms a stable supporting structure of a right triangle with the tilting plate and the facade of the observation tower. One end of the diagonal bracing beam is fixed to the facade of the observation tower by multiple bolts, and the other end is fixed to the tilting plate by bolts.

[0008] Furthermore, the observation platform structure includes a flip plate hingedly connected to the lookout platform and a foldable observation platform fence; the triangular support frame can be rotated, extended or retracted as the flip plate rotates.

[0009] Furthermore, the observation platform fence includes an articulated fence and a folding fence. The lower side of the articulated fence is hingedly connected to the flip plate, and folding fences are respectively connected to both sides of the articulated fence, and the other side of the folding fence is connected to the fixed fence.

[0010] Furthermore, both ends of one side of the flip plate and the observation deck are hingedly connected to extend into the inner side of the observation deck and are fixedly connected with an axle rod, and a hinged ear seat is fixedly provided on the inner side of the observation deck, and the axle rod passes through the hinged ear seat and is rotatably connected thereto; the triangular support frame is a right-angled plate-shaped structure, and the right-angled side on the vertical side is hingedly connected to the inner side of the observation deck through an articulated shaft, a driven bevel gear is provided at the upper end of the articulated shaft, and a driving bevel gear meshing with the axle rod is provided on the axle rod.

[0011] Furthermore, the folding fence includes a plurality of connecting rods arranged in parallel, one end of the connecting rod is hinged to the column of the fixed fence, and the other end is hinged to the column of the hinged fence. The plurality of connecting rods and the columns on both sides form a parallelogram structure that is easy to deform, and the connecting rods on the folding fence are staggered.

[0012] Furthermore, a limit baffle is provided on one end of the flip plate extending into the observation tower, and when the flip plate is rotated and retracted, the limit baffle can be stuck on the inner wall of the observation tower to limit the flip plate.

[0013] Furthermore, a worm gear drive is provided inside the observation tower, and an output end of the worm gear drive is connected to the shaft.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] 1. The observation platform structures extending from both sides of the lookout tower can easily observe the distance between the ship and the lock when the ship passes through the Panama Canal lock, which is more convenient for navigation.

[0016] 2. The observation platform structure is designed to be flippable and retractable, so that the observation platform can be extended when needed and retracted into the boat when not in use. In this way, there will be no observation platform extending outside the hull, which will not affect the overall width of the hull.

[0017] 3. The fence of the observation platform is designed as a hinged fence and a folding fence so that the observation platform structure will not occupy the width of the observation platform when it is folded.

[0018] 4. The limit baffle plate provided on the folding fence can not only limit the rotation of the flip board, but also enhance the fixing effect of the flip board when the flip board rotates and extends out of the observation platform. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0027] The technical solutions in the embodiments of the present invention will be described clearly and completely 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.

[0028] Embodiment 1

[0029] like Figure 1 , 2 , 3, a flip-type Panama Canal platform, including a cab 1, Figure 1The middle is a top view from the top of the cab 1, from which it can be seen that a lookout tower 2 is provided on the periphery of the cab 1, and a fixed fence 3 is provided on the periphery of the lookout tower 2. In the prior art, a fixed welded observation platform extending out of the lookout tower 2 is usually used, which affects the continuity of the lookout tower 2 and increases the width of the hull.

[0030] To this end, the present embodiment adopts a retractable observation platform structure 4 for single use. Specifically, the observation platforms 2 on both sides are provided with an observation platform structure 4 that can be flipped open and extended to the outside of the observation platform 2. The observation platform structure 4 includes a flip plate 5 located at the bottom, and observation platform fences 6 are arranged on three sides of the flip plate 5.

[0031] like Figure 3 As shown, the three sides of the flip board 5 are provided with an observation platform fence 6. The observation platform fence 6 in this embodiment is a fixed type. The three sides are provided with a U-shaped fence that can be connected to the fixed fence 3 outside the observation tower 2. The observation platform fence 6 has a column vertically fixed on the flip board 5, and a horizontal bar is horizontally connected between the columns. It is convenient to protect the safety of the crew when the flip board 5 is extended;

[0032] like Figure 2 As shown, at least one triangular support frame 7 is provided at the bottom of the observation platform structure 4. In actual use, the number of the support frames can be increased to improve the support stability of the flip plate 5. One right-angled side of the triangular support frame 7 is connected to the observation platform 2, and the other side is connected to the bottom of the flip plate 5 to form a stable support for the observation platform structure 4. It can be understood that the observation platform structure 4 in this embodiment can be flipped as a whole and stored in the observation platform 2, or it can be easily disassembled. Specifically, a hinged ear seat 8 is fixed on the observation platform 2, one side of the flip plate 5 is hingedly connected to the hinged ear seat 8, and the bottom of the hinged ear seat 8 is fixed to the bottom surface of the observation platform 2 by multiple bolts; when in use, the observation platform structure 4 can be as shown in FIG. Figure 2 As shown in the schematic diagram on the left side, the whole body is extended outward by rotating with the hinged ear seat 8 as the axis, and the bottom is supported on the triangular support frame 7 preset on the side. When not in use, the whole body can be rotated and stored in the observation tower 2, or the fixing bolts of the hinged ear seat 8 can be removed to dismantle the entire observation platform fence 6.

[0033] The triangular support frame 7 in this embodiment is a diagonal bracing beam 9, which forms a stable supporting structure of a right triangle with the flip plate 5 and the outer facade of the observation tower 2. In order to facilitate disassembly and folding, one end of the diagonal bracing beam 9 is preferably fixed to the outer facade of the observation tower 2 by multiple bolts, and the other end is also fixed to the flip plate 5 by bolts, so that it can be easily removed when not needed.

[0034] Embodiment 2:

[0035] As a further improved design, although the above-mentioned embodiment can perfectly solve the problems listed in the background technology, since it is flipped as a whole, it will still occupy the space of the observation platform 2 when it is folded. In order to solve this problem, the observation platform structure 4 is decomposed into a flip plate 5 and a foldable observation platform fence 6; and the triangular support frame 7 can also automatically rotate, extend or retract as the flip plate 5 rotates.

[0036] Specifically, Figure 4 , 5 As shown in Figures 6 and 7, the observation platform fence 6 includes a hinged fence 10 and a folding fence 11. The lower side of the hinged fence 10 is hingedly connected to the flip plate 5, and the folding fences 11 are respectively connected to both sides of the hinged fence 10. The other side of the folding fence 11 is connected to the fixed fence 3.

[0037] Furthermore, two ends of one side of the flip plate 5 hinged to the observation tower 2 extend into the inner side of the observation tower 2 and are fixedly connected with an axle rod 12. When the flip plate 5 rotates, it rotates with the axle rod 12 as the axis. A hinged ear seat 8 is fixedly provided on the inner side of the observation tower 2, and the axle rod 12 passes through the hinged ear seat 8 and is rotatably connected thereto; the triangular support frame 7 is a right-angled plate-shaped structure, and the right-angled side on the vertical side is hingedly connected to the inner side of the observation platform through a hinge shaft 13. A driven bevel gear 14 is provided on the upper end of the hinge shaft 13, and a driving bevel gear 15 meshing with it is provided on the axle rod 12. In actual use, the rotation of the flip plate 5 causes the axle rod 12 to rotate together, so that the driving bevel gear 15 drives the driven bevel gear 14 to rotate, and the driven bevel gear 14 drives the triangular support frame 7 to rotate, extend out and be supported at the bottom of the flip plate 5. Only one triangular support frame 7 is illustrated in the figure. In actual use, multiple triangular support frames 7 and corresponding bevel gear sets can be set, so as to achieve the effect of driving multiple triangular support frames 7 to extend out for support when the flip plate 5 rotates.

[0038] Furthermore, the folding fence 11 includes a plurality of parallel connecting rods 16, one end of the connecting rod 16 is hinged to the column of the fixed fence 3, and the other end is hinged to the column of the hinged fence 10, and the plurality of connecting rods 16 and the columns on both sides form a parallelogram structure that is easy to deform. The connecting rods 16 on the folding fence 11 are staggered. When folding and retracting, the connecting rods 16 can be staggered with each other to avoid interference, so that the folding fence 11 can be folded and overlapped on the same plane, reducing the thickness of the folded fence. Figure 4 , 6 As shown, when the flip plate 5 is rotated and erected, it can block the gap in the fixed fence 3 to fill the gap, and the hinged fence 10 and the folding fence 11 are simultaneously folded up on the upper part of the flip plate 5, and the triangular support frame 7 is also rotated and retracted into the observation tower 2, so as to achieve the purpose of not occupying the observation tower 2 when folded.

[0039] like Figure 7As shown, a limit baffle 17 is provided at one end of the flip plate 5 extending into the observation tower 2. When the flip plate 5 is rotated and retracted, the limit baffle 17 can be stuck on the inner wall of the observation tower 2 to limit the flip plate 5. The figure shows that when the flip plate 5 is retracted or extended, the limit baffle 17 just blocks the adjacent inner walls of the observation tower 2 on both sides, which can not only limit the rotation angle and prevent excessive rotation, but also improve the support effect when the flip plate 5 is extended. Figure 5 As shown, a worm gear drive 18 is further provided inside the observation tower 2, and the output end of the worm gear drive 18 is connected to the shaft 12, and the worm gear drive 18 can realize automatic driving of the observation platform structure 4 to be retracted and extended.

[0040] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
