Specifically, in this embodiment, as shown in
In this embodiment, the compartment 2 may be filled with a filler having a density smaller than the density of seawater. The filler is filled in the compartment 2 and occupies the space inside the compartment 2. When the seawater is immersed in the compartment 2, only a small space can accommodate the seawater, thereby reducing the occurrence of sinking of the entire operation platform when the seawater flows back into the compartment 2, and further improving the practicality of the operation platform. Specifically, the filler may be foam or the like.
In the embodiment of the present application, the frame structure 1 may be a steel frame welded by I-steel or channel steel, the floor board 3 may be a board subjected to preservative treatment, the compartment 2 may be a quadrangular compartment welded by a plurality of steel plates, and the filler may be polyethylene foam; and the surfaces of the steel frame and the quadrangular compartment of this embodiment are coated with a corrosion protection paint to reduce the corrosion damage of corrosive seawater to the corresponding steel frame and quadrangular compartment made of steel plates. Here is the specific form of each component on the operation platform, where the frame structure 1 is welded by multiple pieces of I-steel or channel steel or connected by connectors, so the fastness of connection is strong, the production is simple and convenient, mass production can be achieved, and the production cost can be effectively reduced; the surfaces of the floor board 3, the frame structure 1 and the compartment 2 are all coated with the corrosion protection paint, which can effectively reduce the corrosion damage to the components in contact with the seawater, effectively reduce the damage of the components such as breakage and leakage, and correspondingly prolong the service lives of the components and the operation platform.
The compartment 2 is a truncated quadrangular prism, the flared end of the quadrangular prism is connected to the frame structure 1, the reduced end is located at the bottom, and the quadrangular prism reduced from top to bottom can further reduce the impact force of seawater on the compartment 2 and improve the support stability of the compartment 2 to the frame structure 1 while floating; the reduced end of the compartment 2 can also be used for supporting to facilitate the placement of the operation platform on the land. Specifically, the compartment 2 may also be a truncated cone.
In order to reduce the occurrence of operator's fall caused by displacement of the floor board 3 when the operator is walking on the operation platform, in the embodiment of the present application, limit safety piles 11 may be fixedly disposed at end corners of the top surface of the frame structure 1, grooves 12 are arranged at end corners of the floor board 3, and the grooves are engaged with the limit safety piles 11 in one-to-one correspondence. The floor board 3 is clamped into the limit safety piles 11 of the frame structure 1 through the grooves 12, the floor board 3 is fixedly connected to the frame structure 1 correspondingly and cannot be displaced relative to the frame structure 1 in the horizontal direction, and when there is certain bump on the sea surface or the operator walks on the operation platform, the floor board 3 is not easily displaced, thereby ensuring the reliability of the operation platform and the balance of the operator on the operation platform; specifically, limit safety piles 11 may be disposed at four corners of the frame structure 1, and the four limit safety piles 11 simultaneously fix the four end corners of the floor board 3 to further improve the fixing fastness of the floor board 3; in addition, the limit safety piles 11 disposed at the end corners of the frame structure 1 facilitate the operator to bind other equipment or fix the operation platform.

Specifically, in this embodiment, the frame structure of the operation platform may be rectangular, and the long sides of two adjacent frame structures are correspondingly detachably fixed. The long sides of two or more operation platforms are connected together, the wide sides of the plurality of operation platforms together form the long side of the integrated working platform, the two compartments 2 on two sides of the plurality of operation platforms in the length direction are at the bottom of the integrated working platform, two rows of floating compartments are formed on two sides in the width direction (each row of floating compartments is composed of a plurality of compartments 2 on the same side of the plurality of operation platforms), and the two rows of floating compartments at the bottom of the integrated working platform support two ends as two fulcrums, so the support stability is stronger; and a passage is formed between the two rows of floating compartments (the gaps between the two compartments 2 on the plurality of operation platforms form the passage together), and the seawater can flow through the passage, thereby reducing the impact force and further improving the stability and balance.
That is, the integrated working platform assembled from a plurality of operation platforms is similar to a single operation platform in form, and has all the characteristics of the single operation platform.
In addition, after the plurality of operation platforms are fastened to build the integrated working platform, a hoist bracket 52 can be hinged to the deck, and the free end of the hoist bracket 52 can extend out of the deck; a hoist 5 is also fixedly connected to the deck 5, the hoist 5 includes a driving motor and reels 53 in transmission connection, the reels 53 are wound with wire ropes 51, and the rotation direction of the reels 53 is identical to that of the hoist bracket 52. The hoist bracket 52 can be rotated around a hinged joint on the deck. On the one hand, when the hoist bracket 52 is rotated to the outside of the deck, the operator can quickly build a temporary bridge with other operation platform or a bridge during landing. On the other hand, the hoist bracket 52 can be used as a bracket or swing arm to transport goods, thereby facilitating the carrying and transfer of goods or materials, and reducing the wear and damage of the deck when the wire rope 51 directly acts on the deck.
Specifically, the hoist 5 may include two reels 53, and the two reels 53 are arranged side by side in a axial direction thereof and are in transmission connection with a driving end of the driving motor. When goods to be transported are heavy, the two reels 53 can be used at the same time, and the free end of the wire rope 51 on the two reels 53 are connected with the goods to carry the goods together, thereby improving the bearing strength of the hoist 5 and the transportation stability of the goods, and reducing the occurrence of breakage of the single wire rope 51 when transporting goods or damage when the force bearing point of goods bears a large force. Specifically, the hoist 5 may be provided with one driving motor to drive the two reels 53 at the same time, or provided with two driving motors to drive the two reels 53 in one-to-one correspondence.
In this embodiment, fixing lugs 6 may be provided on the deck, and the fixing lugs 6 are pivotally connected to the hoist bracket 52 by rotating shafts. Here is a specific form of splicing of the hoist bracket 52 to the deck, where the fixing lugs 6 are disposed on the deck, and the fixing lugs 6 are hinged to the hoist bracket 52, so that on the basis of rotation of the hoist bracket 52 on the deck, the damage to the deck caused by direct connection of the hoist bracket 52 to the deck is reduced, and the support strength of the deck to the operator and goods is ensured.
Specifically, in this embodiment, the hoist bracket may include two longitudinal beams and a plurality of transverse beams, the two longitudinal beams are arranged in parallel, and the plurality of transverse beams are connected between the two longitudinal beams and are parallel to each other; two fixing lugs 6 may also be provided, and ends of the two longitudinal beams at a same end are respectively pivotally connected to the two fixing lugs 6 through the rotating shafts. Here is a specific form of the hoist bracket 52, where the plurality of transverse beams are supported between the two longitudinal beams to improve the relative fastness and support stability between the two longitudinal beams; when the hoist bracket 52 is used as a connected temporary bridge, the transverse beams can be for the operator to step on; in addition, the ends of the two longitudinal beams are correspondingly pivotally connected to the two fixing lugs 6, so the fastness of connection is stronger, and the hoist bracket 52 is more stable against the rotation of the deck.
In this embodiment, a support frame 8 may also be fixed on the deck, the support frame 8 is located outside the hoist bracket 52, and the hoist bracket 52 may rotate outward to abut against the support frame 8. When goods need to be transported, the hoist bracket 52 is rotated outward to lap the support frame 8, the wire ropes 51 bypass the hoist bracket 52 from above, the goods are connected to the free end of the wire rope 51 and suspended under the support of the hoist bracket 52 and rise constantly under the tightening action of the hoist 5 till the goods tightly abut against the hoist bracket 52, the hoist bracket 52 is rotated inward around a hinged joint thereof under a joint action of the goods and the wire ropes 51 to transport the goods to the deck, and the goods are taken down to complete the transportation. The support frame 8 supports the hoist bracket, which can reduce, on the one hand, the damage to the deck when the hoist bracket 52 is rotated to the outside and supported on the deck; and on the other hand, when the wire ropes 51 pull the hoist bracket 52 to rotate around the hinged joint, the support frame 8 supports the hoist bracket 52 within certain height and angle, which can effectively reduce the rotation angle of the hoist bracket 52 driven by the wire ropes 51, and correspondingly reduce the external work of the hoist 5.
In this embodiment, a rotating roller 7 may be pivotally connected to the free end of the hoist bracket 52. When the hoist bracket 52 is supported by the support frame 8, the wire ropes 51 bypass the rotating roller 7 to transport the goods. When the wire ropes 51 are continuously tightened onto the reels 53, the rotating roller 7 continuously rotates with the transmission of the wire ropes 51, and the rotating roller 7 can greatly reduce the friction at the time of movement relative to the wire ropes 51 while supporting the wire ropes 51, which can reduce the wear of the wire ropes 51 on the one hand and can also reduce the working resistance of the hoist 5 on the other hand.
In this embodiment, power systems 4 may be provided on the operation platforms, and the power systems 4 are configured to drive the operation platforms to move on the sea. During offshore operation, periodic typhoon attacks are usually encountered, and when the corresponding power systems 4 are disposed on the operation platforms, the operator can transfer the corresponding working platform to a safe area such as a harbor through the power systems 4 before the typhoon attacks, so as to reduce the damage caused by the typhoon to the working platform. In addition, the integrated working platform having certain power systems 4 can be used as an offshore rescue platform for people or goods that need rescue in an emergency, and therefore has wide applications.
