Description

Technical Field

[0001] The present invention relates to the field of ship transportation equipment, and in particular to a steel structure system for a ship transportation offshore platform. Background Art

[0002] Ship transportation is an important mode of transportation that uses ships to transport passengers or goods by water. In particular, in the transportation of goods, it undertakes a large number of bulk goods and containerized goods. Usually, bulk goods do not need to be individually packaged during transportation and storage, but are transported in bulk or large packages. During the loading process, a large number of bulk goods are usually first transported to the ship, and then planned and transferred separately; For example, in the prior art, a patent application with an application publication number of CN115367510A discloses a creeping large-segment steel beam loading and transportation platform, which involves the field of steel structure loading and transportation technology. domain, it can climb up the steps by controlling the extension and contraction of the hydraulic cylinder without causing the cargo to tilt, which can effectively overcome the dynamic height difference between the ship and the shore, so that the steel beam can be transported on board smoothly; another patent with the announcement number CN215923835U discloses a cargo lifting device for ship transportation, including a placement platform and a lifting bracket, a lifting bracket is installed at the bottom of the placement platform, a rotating shaft is fixedly installed at one end of the placement platform, a rotating plate is rotatably connected in the rotating shaft, a limiting pin is installed on the placement platform, a limiting hole is provided on the outer wall of the rotating plate, and a clamping assembly is arranged inside the placement platform. By adopting a rotating plate with a rotatable connection, when the cargo needs to be transported, the cargo can be pushed into the placement platform or unloaded from the placement platform by pushing, which effectively reduces the effort required for transporting the cargo and increases the work efficiency. By inserting the limiting pin into the two sets of limiting holes on the rotating plate, the steering limiting effect on the rotating plate can be quickly formed, which avoids the accidental opening of the rotating plate during the transportation of the device.

When the first connecting gear 8 rotates, it can drive the connecting beam 3 to move at the bottom of the supporting beam by meshing with the first connecting rack 7, thereby driving the transportation equipment 5 to move forward and backward on the lower side of the supporting beam; the lower side of the crossbeam 4 is fixedly connected with a second connecting rack 11 along the length direction, and the lower side of the second connecting rack 11 is meshed with a second connecting gear 10. The second connecting gear 10 is rotatably connected to the connecting plate 12, and a second moving motor 9 is arranged on the front side of the second connecting gear 10. The second moving motor 9 is fixedly connected to the connecting plate 12. When the second moving motor 9 rotates, it can drive the second connecting gear 10 to rotate and mesh with the second connecting rack 11, thereby driving the transportation equipment 5 to move left and right at the lower end of the crossbeam 4, thereby controlling the transportation equipment 5 to move left and right, front and back arbitrarily. At the same time, the frame-shaped bracket 2 can also move on the surface of the ground rail 1, which is convenient for changing the transportation position, and fully plays a role in saving construction costs and facilitating construction operations;

[0036] The transport device 5 includes a protective shell 13, a clamping device installed on the left side of the protective shell 13 and capable of swinging left and right, and a lifting device located on the right side of the clamping device. The clamping device is used to clamp the goods. The bottom of the protective shell 13 is fixedly connected with a plurality of universal wheels for supporting the transport device for easy movement. The lifting device includes a placement rack 35 and a lifting rack 37 installed on the inner side of the placement rack 35 and capable of swinging upward in a circle. The goods are placed on the placement rack 35 by swinging the clamping device left and right. When the lifting rack 37 swings upward, the goods on the placement rack 35 are intermittently transferred upward, which is used to accumulate the goods before transferring them when transferring the goods, thereby improving the transfer efficiency.

[0037] The clamping device includes two mounting plates 16 arranged correspondingly in front and back, and the inner sides of the mounting plates 16 are respectively slidably connected with lifting frames 22 that move up and down. When the mounting plates 16 swing left and right, a structure is formed in which the lifting frames 22 move up and down. When the lifting frames 22 are lifted or lowered, the goods are clamped and transported. A swing plate 24 is respectively arranged between the two lifting frames 22. The middle of the swing plate 24 is respectively rotatably connected to the surface of the corresponding lifting frames 22. The corresponding ends of the two swing plates 24 are respectively connected with pressing plates 27 that can move along the length direction of the swing plates 24. Spring assemblies are respectively connected between the pressing plates 27 and the corresponding swing plates 24. An elastic reset component that provides resistance for the inner end of the swing plate 24 to swing upward is installed between the outer end of the swing plate 24 and the lifting frame 22. When the mounting plate 16 swings to the left, the lifting frame 22 moves downward, and the inner ends of the two swing plates 24 swing upward under the obstruction of the goods. The lifting frame 22 moves upward when the mounting plate 16 swings to the right, and the inner ends of the two swing plates 24 swing downward under the action of the friction force with the inner goods and the push of the spring return parts, and strengthen the squeezing effect on the goods, improve the firmness of the clamping of the goods, and drive the goods to be transported to the right side. When the two swing plates 24 swing inward under the push of gravity and the elastic return parts, in order to avoid damaging the goods and further improve the clamping effect, the swing plate 24 will move outward accordingly and squeeze the spring assembly, and continue to apply pressure to the goods through the spring assembly. When the inner end of the swing plate 24 swings downward to make the inner end of the swing plate 24 fit the goods, the friction force on the goods is the largest, and then the clamping force on the goods is also the largest, which can fully improve the fixing effect on the goods.

[0038] Furthermore, the elastic reset component includes an arc plate 23 fixedly connected to the left and right sides of the lower outer end of the mounting plate 16, respectively. The surface of the arc plate 23 is provided with an arc groove, which is coaxial with the rotation point in the middle of the swing plate 24. An arc spring 25 is coaxially arranged inside the arc groove. The left and right sides of the outer end of the swing plate 24 are respectively bent upward by ninety degrees, and one end of the swing plate 24 bent upward is fixedly connected with a connecting shaft 26, which is slidably connected to the arc groove and the arc spring 25 is respectively located on the lower side of the connecting shaft 26. When the swing plate 24 swings, the connecting shaft 26 can slide inside the arc groove and squeeze the arc spring 25. The arc spring 25 can provide a driving force for the reset of the swing plate 24 through its own elastic force.

[0039] Furthermore, the spring assembly includes a limiting rod 28 fixedly connected to the left and right sides of the outer end of the pressure plate 27, and the inner ends of the swing plates 24 corresponding to the limiting rods 28 are respectively provided with spring grooves toward the outside, and the limiting rods 28 are respectively slidably connected to the spring grooves, and pressure springs 29 are respectively arranged inside the spring grooves. The pressure springs 29 are respectively located at the outer ends of the limiting rods 28. The resistance encountered when the inner end of the swing plate 24 swings inward can be converted into a driving force to push the limiting rod 28 outward and compress the pressure spring 29. The pressure spring 29 provides continuous pressure, and the cargo is clamped and fixed under the clamping force when the swing plate 24 swings downward.

[0040] The front and rear sides of the left end of the protective shell 13 are respectively fixedly connected with a guide plate 15, and the upper end of the mounting plate 16 is respectively provided with a first parallel rod 19 and a second parallel rod 20 arranged in parallel with each other. A transmission shaft is respectively fixedly connected between the two first parallel rods 19 and the two second parallel rods 20, and the transmission shaft is rotatably connected to the guide plate 15. The upper ends of the first parallel rod 19 and the second parallel rod 20 are respectively hinged to the surface of the guide plate 15, and the surface of the guide plate 15 is respectively provided with a guide groove 30. The outer ends of the lifting frame 22 are respectively fixedly connected with the lifting horizontal plate 17, and the outer ends of the lifting horizontal plate 17 are respectively fixedly connected with the matching pin shaft 18, and the matching pin shaft 18 is respectively slidably matched with the guide groove 30; the two sides of the guide groove 30 are respectively inclined groove structures inclined outward, such as Figure 6 As shown, the first parallel rod 19 and the second parallel rod 20 form a parallelogram structure. When the first parallel rod 19 and the second parallel rod 20 swing to the right, the mounting plate 16 and the lifting frame 22 can be driven to move to the right at the same time, and the mounting plate 16 and the lifting frame 22 are kept parallel. When the lifting frame 22 moves to the right, under the action of the inclined grooves on both sides of the guide groove 30, the lifting frame 22 will first move upward while moving, and then move downward after being transferred to the right, so as to achieve the effect of lifting and placing goods. When lifting goods, the swing plate 24 and the pressure plate 27 are used to clamp and fix the goods, and when placing goods, the fixing effect on the goods is released.

[0041] The surfaces of the guide plates 15 on the right side of the mounting plate 16 are respectively provided with arc-shaped baffles 31, the outer ends of the arc-shaped baffles 31 are respectively fixedly connected to mounting rods 33, the mounting rods 33 are respectively slidably connected to the guide plates 15, and the surfaces of the mounting rods 33 are respectively sleeved with return springs 34, and a matching rod 32 is fixedly connected between the left and right corresponding swing plates 24. During the transfer of goods, when the matching rod 32 touches the arc-shaped baffle 31, it will push the arc-shaped baffle 31 to move outward and squeeze the return spring 34, so that the arc-shaped baffle 31 no longer blocks the matching rod 32, and when the mounting plate 16 swings to the right, the matching rod 32 is located at the lower side of the arc-shaped baffle 31, and in the process of placing goods, the goods touch the Then, when the swing plate 24 continues to move downward, the inner end of the swing plate 24 can be driven to swing upward under the action of friction, so that the matching rod 32 swings outward, so that it is located at the lower side of the matching rod 32, and then when the mounting plate 16 moves to the left, the lifting frame 22 moves upward and resets, and the matching rod 32 is blocked by the arc baffle 31 and continuously moves outward while moving upward, so that the pressure plate 27 no longer clamps the goods, and the goods stay on the placement plate 36. Then, during the continuous movement of the lifting frame 22, the matching rod 32 is separated from the contact with the arc baffle 31, and the swing plate 24 can be reset under the push of the arc spring 25.

[0042] A plurality of placement plates 36 with equal spacing are fixedly connected to the front and rear sides of the left end of the placement rack 35 from bottom to top, respectively. A plurality of lifting plates 38 with equal spacing are fixedly connected to the left end of the lifting rack 37 from bottom to top, respectively. The height of the lifting plates 38 arranged side by side is lower than the placement plates 36. The left end of the bottom placement plate 36 is in an upwardly inclined structure.

[0043] The right end of the lifting frame 37 is fixedly connected to a fixed frame 39, and cams 40 are respectively arranged on the upper and lower sides of the front end of the fixed frame 39, and the cams 40 are respectively rotatably connected to the inner wall of the protective shell 13, and the front ends of the cams 40 are respectively rotatably connected to the fixed frame 39, and the middle parts of the cams 40 are respectively fixedly connected to drive pulleys, and a first drive belt 41 is sleeved between the upper and lower drive pulleys. An alternating transmission control structure is connected between the lower drive pulley and the swing point of the second parallel rod 20 on the left side. When the lower drive pulley rotates under the transmission of the control structure, the two cams 40 can be driven to rotate synchronously under the transmission of the first drive belt 41. When the two cams 40 rotate synchronously, the fixed frame is driven to swing upward to the left circumference, thereby driving the lifting frame 37. The lifting frame 37 is in a state of upward swinging in a circle. When the lifting frame 37 swings upward, the lifting plate 38 continuously transfers the goods to the upper placement plate 36, providing a placement space for the lower placement plate 36, which is convenient for temporary storage of goods and unified transfer, thereby effectively improving the transfer efficiency. When the second parallel rod 20 swings, the first parallel rod 19 and the second parallel rod 20 can be synchronized to swing, and the goods can be placed on the lower placement plate 36 through the clamping device, so that when operating the control structure, the first parallel rod 19 and the second parallel rod 20 can be first controlled to swing to the right to place the goods on the lower placement plate 36, and then the lifting frame 37 can be controlled to swing upward to continuously transfer the goods on the lower side to the upper placement plate 36.

[0044] The control structure includes a control motor 14 fixedly connected to the protection frame and an active dial wheel 42 fixedly connected to the output end of the control motor 14.

When the control motor 14 rotates, the groove wheel 43 on the left side is first driven to rotate intermittently, and the active dial wheel 42 and the groove wheel 43 form a 90-degree groove wheel intermittent transmission structure. When the groove wheel 43 on the left side rotates 90 degrees, the groove wheel 43 on the left side rotates 90 degrees.
