Description

Technical Field

[0001] The invention relates to the technical field of ships, and in particular to a structural component capable of replacing an Austenite. Background Art

[0002] For bulk carriers arriving at Australian ports to load and unload cargo, dock workers need to be able to reach into the cargo hold to check the loading and unloading of cargo and comply with the relevant requirements of the "Amendment to Cargo Handling Equipment" promulgated by the Australian Maritime Safety Authority. Therefore, fixed access facilities (commonly known as "Australian ladders") will be set up in the cargo hold.

[0003] For conventional bulk carriers, the Australian ladder is usually arranged between the groove structures of the transverse bulkheads, and is composed of a combination of a straight ladder and a rotating ladder and an intermediate platform, or an alternating arrangement of straight ladders and platforms, and the entrance is generally set at the top pier bottom plate. Dock workers enter the top pier area through the entrance on the main deck, and then go down to the Australian ladder at the entrance at the top pier bottom plate to reach the double bottom of the cargo hold.

[0004] The Australian ladder consists of a straight ladder, a spiral ladder, a supporting column, a platform, a spiral ladder protection tube, railings and handrails, a protective chain, etc. The basic structure is relatively complex, and the connection with the transverse bulkhead needs to be added with a pad or special treatment, which increases the workload and difficulty of cargo hold section construction. Due to the complex structure, when cleaning the cargo hold, some corners of the Australian ladder cannot be thoroughly cleaned and need to be manually cleaned, which increases the ship's time in port and the cost of cleaning the hold; when dock workers go up and down the Australian ladder, they need to be careful to avoid the risk of slipping and falling. As a protruding structure in the trough bulkhead, the Australian ladder is large in size and occupies precious cargo hold volume. The layout of the Australian ladder has relatively high requirements for the ship's structural design. When designing the cargo hold trough bulkhead, in order to leave enough space for the Australian ladder, it is necessary to have a sufficiently high trough depth and panel, which invisibly increases the plate thickness of the trough bulkhead, thereby increasing the weight of the ship. Summary of the invention

[0005] The technical problem to be solved by the present invention is to overcome the above-mentioned defects of the prior art and provide a structural member that can replace the Australian ladder.

[0006] The present invention solves the above technical problems through the following technical solutions:

[0007] A structural member that can replace the Australian ladder, which is arranged between the top pier above the trough-shaped bulkhead and the bottom pier below the trough-shaped bulkhead; it includes a lifting box, a lifting steel cable connected to the top of the lifting box, a pulley block arranged above the lifting box and an electric winch for controlling the lifting steel cable; the electric winch is fixed to the inner wall of the top pier, and the lifting steel cable is passed through the pulley block; a through hole for the lifting box to pass through is opened on the bottom plate of the top pier; a guide rail bracket for providing a vertical guiding function for the lifting box is fixed on the inner wall of the top pier; a foldable ladder that can be stored in the lifting box is arranged in the lifting box; one end of the ladder is fixedly connected to the lifting box; a buffer seat for providing a buffer force for the lifting box is fixed on the top plate of the bottom pier.

[0008] The guide rail brackets are located on the sides of the lift box.

[0009] The pulley block is fixed at the bottom of the main deck.

[0010] The lift box is in the shape of a cuboid.

[0011] The through hole is rectangular.

[0012] The lifting cable has a length that allows the lifting box to be lowered onto the buffer seat.

[0013] The ladder is a portable ladder.

[0014] The other end of the ladder has non-slip feet.

[0015] The ladder has a length that can extend from above the cushion seat to the bottom of the cargo hold.

[0016] The material of the top of the buffer seat is rubber.

[0017] The beneficial effects of the present invention are as follows: the overall weight of the present invention is significantly lighter than the total weight of the traditional Australian ladder, thereby saving the empty ship weight and construction costs. The present invention does not occupy the cargo hold volume, and only needs to be lowered into the cargo hold when in use, thereby saving precious cargo hold volume. The present invention solves the problem that the Australian ladder cannot be cleaned thoroughly during tank cleaning and requires manual fine cleaning, reducing the time in port and thus reducing the cost of using the ship; at the same time, the present invention solves the problem of casualties caused by slipping soles when people get on and off the Australian ladder in the past, providing the staff with a safe and comfortable way of passage. Compared with the traditional Australian ladder, the present invention has a simple structure and is easy to maintain; it can make full use of the embedded structural characteristics of the grooved bulkhead, will not interfere with the design of the hull structure, and can design the grooved bulkhead more freely, thereby reducing the weight of the ship.

[0023] A preferred embodiment is given below, and the present invention is described more clearly and completely in conjunction with the accompanying drawings.

[0024] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, a structural member that can replace the Australian ladder is arranged between the top pier 11 above the corrugated bulkhead 10 and the bottom pier 12 below the corrugated bulkhead.

[0025] The structural components that can replace the Australian ladder include a lifting box 20, a lifting cable 21 connected to the top of the lifting box, a pulley block 22 arranged above the lifting box, and an electric winch 23 for controlling the lifting cable.

[0026] The pulley block 22 is fixedly mounted on the bottom of the main deck 30 .

[0027] The electric winch 23 is fixed on the inner wall of the top pier, and the lifting cable 21 is passed through the pulley block 22.

[0028] The top pier bottom plate 13 is provided with a through hole 14 for the lifting box to pass through. The lifting box 20 is in the shape of a cuboid; the through hole 14 is in a rectangular shape.

[0029] The inner wall of the top pier is fixed with a guide rail bracket 15 for providing a vertical guiding function for the lifting box. The guide rail bracket 15 is located at the side of the lifting box.

[0030] A foldable ladder 24 is provided in the lift box 20. In this embodiment, the ladder is a portable ladder. In a preferred embodiment, the ladder is a flip-type portable ladder.

[0031] The ladder 24 has a length that can extend from above the cushion seat to the bottom of the cargo hold.

[0032] One end of the ladder 24 is fixed to the lift box 20. The other end of the ladder 24 has an anti-skid ladder foot (the anti-skid ladder foot is small in size and is not shown in the figure). When the lower end of the ladder touches the bottom of the cargo hold, the anti-skid ladder foot can prevent slipping and shaking.

[0033] A buffer seat 17 for providing a buffer force for the lifting box is fixedly arranged on the bottom pier top plate 16. The material of the buffer seat 17 top is rubber.

[0034] The lifting cable 21 has a length that allows the lifting box to be lowered onto the buffer seat.

[0035] like Figure 5 As shown, the dotted area 33 is used to store the folded ladder.

[0036] The use process of the present invention is:

[0037] If the staff needs to go down from the main deck to the double bottom of the cargo hold, they can first enter the lift box from the top pier area, start the descending function through the control panel inside the lift box, and the electric winch fixed on the top pier bulkhead starts working, controlling the lifting cable to drive the elevator to descend at a uniform speed. The lift box enters the cargo hold area through the opening at the bottom plate of the top pier. The lift box can be controlled to stop at different descending depths through the control panel. When the lift box stops, the brake device equipped with the electric winch is activated to avoid accidental descent of the lift box and ensure the safety of passengers. The lift box can be lowered to the position of the buffer seat on the top plate of the bottom pier. The buffer seat is a buffer mechanism set to ensure the safety and comfort of passengers. The staff opens the door of the lift box, adjusts the flip portable ladder to the double bottom of the cargo hold, and enters the double bottom of the cargo hold through the portable ladder.

[0038] On the contrary, if the staff needs to leave the double bottom of the cargo hold and go up to the main deck, they can enter the lifting box by means of the flip portable ladder, then retract the flip portable ladder and store it in the dotted area 33, then start the ascending function by using the control button in the lifting box, the electric winch fixed on the top pier partition starts to work, and controls the lifting steel cable to drive the lifting box to rise at a uniform speed, the lifting box enters the top pier area through the opening at the bottom plate of the top pier, and stops until it rises to the position where the bottom of the lifting box is flush with the bottom plate of the top pier, and the staff walks out of the lifting box to the top pier area.

[0039] When the lifting box passes through the through hole at the bottom plate of the top pier and enters the cargo hold area, the lifting box can stop at any time between the top pier and the bottom pier. When the lifting box stops, the staff can observe the cargo in the cargo hold.

[0040] The present invention has the following advantages:

[0041] 1. The overall weight of the present invention is significantly lighter than that of the traditional Australian ladder, thereby saving the empty ship weight and construction cost.

[0042] 2. The present invention does not occupy the cargo hold volume and only needs to be lowered into the cargo hold when in use, thereby saving precious cargo hold volume.

[0043] 3. The present invention solves the problem that the tank cannot be cleaned thoroughly and needs manual cleaning in the past, thus reducing the time in the port and thus reducing the cost of using the ship.

[0044] 4. The present invention solves the problem of casualties caused by slipping soles when people go up and down the ladder in the past, and provides workers with a safe and comfortable way of passing.

[0045] 5. Compared with the traditional Australian ladder, the present invention has a simple structure and is easy to maintain.

[0046] 6. The present invention can make full use of the embedded structural characteristics of the grooved bulkhead, will not interfere with the design of the hull structure, and can design the grooved bulkhead more freely, thereby reducing the weight of the ship.

[0047] The present invention arranges a through-lift from top to bottom in a limited space, has a simple structure and is convenient to construct, does not affect the cabin capacity, is convenient for cabin cleaning, and can also provide a safe and comfortable passage for staff, has a low cost, and will not have too much impact on ship design.
