Description

Technical Field

[0001] The present invention relates to the technical field of shipbuilding, and in particular to a large object transportation device for container ship construction. Background Art

[0002] During the construction of container ships, some sections are long and narrow with no openings at the top. It is inconvenient for outfitting parts and equipment to enter and exit such sections. It is impossible to use a crane to lift workpieces from above the long and narrow sections into the long and narrow sections. Usually, people need to enter the long and narrow sections from the side by means of a chain block.

[0003] Chinese Patent with the authorization announcement number CN215794359U provides a large object transportation device in a long and narrow space, which includes tracks. The tracks are laid in the long and narrow sections. One section of the tracks is laid at the entrance of the long and narrow section, and the other end of the tracks is laid at the exit of the long and narrow section. A set of transport vehicles are slidably arranged on the tracks. Steel wire ropes are arranged between the transport vehicles. A winch is arranged at the exit of the long and narrow section, and the winch is used to tow the transport vehicles. After placing the large object on the transport vehicles on both sides, the winch is started. The winch towes the transport vehicles to move synchronously, and the transport vehicles drive the large object to move, realizing the effect of transporting the large object in the long and narrow section.

[0004] In the process of implementing the present application, the inventors found that at least the following problems exist in this technology: Due to the limited space in the long and narrow section and the large size of the large object, the tracks are laid on the ground of the long and narrow section, and the tracks greatly squeeze the ground space in the long and narrow section. When a transport vehicle breaks down during the transportation of a large object in the long and narrow section, the large object will block the long and narrow section, resulting in the ground being unable to ensure smoothness, paralyzing the ground transportation in the long and narrow section, and then causing a situation of idling work, thereby slowing down the construction progress. Summary of the Invention

[0005] In order to facilitate the transportation of large objects in the long and narrow section and maintain the construction progress, the present application provides a large object transportation device for container ship construction.

[0006] The large object transportation device for container ship construction provided by the present application adopts the following technical solutions:

[0007] A large object transportation device for container ship construction includes a set of support frames. One end of the support frame is located at the entrance of the long and narrow section, and the other end of the support frame is located at the exit of the long and narrow section. Transport grooves are opened on the opposite surfaces of the support frames. A set of transport beams are slidably arranged between the transport grooves. A synchronization component is commonly arranged on the transport beams, and the synchronization component is used to drive the transport beams to move synchronously. Electric hoists are fixedly arranged at the bottom of the transport beams, and the electric hoists are used to lift objects. Mounting components are commonly arranged at both ends of the support frames, and the mounting components mount the support frames in the long and narrow section.

[0008] By adopting the above technical solution, the support frame is installed in the long and narrow section through the installation component, with one end of the support frame located at the inlet of the long and narrow section and the other end of the support frame located at the outlet of the long and narrow section. When it is necessary to transport large objects in the long and narrow section, an electric hoist is used to lift the large object at the inlet of the long and narrow section, and then the synchronous component is started. The synchronous component drives the transport beam to move synchronously, so that the large object is transported in the long and narrow section, keeping the ground unobstructed and maintaining the construction progress.

[0009] Preferably, one end of the transport beam is slidably arranged in one transport groove, and the other end of the transport beam is slidably arranged in the other transport groove. Pulleys are rotatably arranged at both ends of the transport beam, and the pulleys are rollingly arranged in the transport grooves.

[0010] By adopting the above technical solution, the synchronous component drives the transport beam to move synchronously, and the pulleys roll in the transport grooves, reducing the friction between the transport beam and the inner wall of the transport groove, which is convenient for the transport beam to drive the large object to move.

[0011] Preferably, the installation component includes a group of mounting plates. Mounting holes are formed in the mounting plates for the support frame to be inserted. A plurality of positioning holes are formed in the bottom wall of the mounting plates, positioning bolts are arranged in the positioning holes, a plurality of positioning grooves are formed in the bottom wall of the support frame, and the positioning bolts penetrate through the positioning holes and are threadedly connected with the positioning grooves.

[0012] By adopting the above technical solution, one mounting plate is installed at one end of the inlet of the long and narrow section, and the other mounting plate is installed at one end of the outlet of the long and narrow section. According to the length and width of the long and narrow section, the position of the support frame in the mounting hole is adjusted. After the adjustment is completed, the positioning bolts penetrate through the positioning holes and are threadedly connected with the positioning grooves, so that the support frame is connected to the mounting plate.

[0013] Preferably, the synchronous component includes a connecting rope, a towing rope, a synchronous roller and a synchronous motor. The synchronous roller and the synchronous motor are both arranged on one of the mounting plates. The synchronous roller is rotatably connected to the mounting plate, and the synchronous motor is used to drive the synchronous roller to rotate. One end of the towing rope is wound around the synchronous roller and connected to the synchronous roller, the other end of the towing rope is fixedly connected to the transport beam near the outlet end of the long and narrow section, one end of the connecting rope is connected to one transport beam, and the other end of the connecting rope is connected to the other transport beam.

[0014] By adopting the above technical solution, when the synchronous motor is started, the synchronous motor drives the synchronous roller to rotate. The synchronous roller rotates to drive the towing rope to be wound on the synchronous roller. Then the towing rope pulls the transport beam near the outlet end of the long and narrow section to move. The movement of the transport beam near the outlet end of the long and narrow section pulls the connecting rope to move, and the connecting rope drives the transport beam near the inlet end of the long and narrow section to move. Thus, the synchronous movement of the transport beams drives the large object to move.

[0015] Preferably, the synchronization component further includes a set of guide rods. One of the guide rods is fixedly arranged in one of the transport grooves, and the other guide rod is fixedly arranged in the other transport groove. The transport beam is sleeved on the guide rods.

[0016] By adopting the above technical solution, since the guide rods penetrate through the transport beam, the transport beam is limited by the guide rods during the movement process, so that the transport beam is not likely to be skewed during the movement process.

[0017] Preferably, a reset roller and a reset motor are arranged on the other mounting plate. The reset roller is rotatably connected to the mounting plate. The reset motor is used to drive the reset roller to rotate. A reset rope is wound around the reset roller. One end of the reset rope away from the reset roller is fixedly connected to the transport beam near the exit of the long and narrow section.

[0018] By adopting the above technical solution, during the transportation of large objects, the reset motor rotates forward to apply a reverse traction force to the transport beam on the side close to the reset roller, reducing the inertial movement of the transport beam. When the transportation of large objects is completed, the synchronous motor stops, and the reset motor rotates in the reverse direction. The reset motor drives the reset roller to rotate, and the reset roller rotates to drive the reset rope to be wound on the reset roller. Then the reset rope pulls the transport beam near the entrance of the long and narrow section to move. The transport beam near the entrance of the long and narrow section moves to pull the connecting rope to move, and the connecting rope drives the transport beam near the exit of the long and narrow section to move. Then the transport beam moves to the entrance end of the long and narrow section.

[0019] Preferably, connecting seats are fixedly arranged on the top of the transport beams. One end of the connecting rope penetrates through the connecting seat near the entrance of the long and narrow section and is fixedly connected to the connecting seat. The other end of the connecting rope penetrates through the connecting seat near the exit of the long and narrow section, and a locking ring is fixedly arranged on the end wall. A locking bolt is arranged in the locking ring. A plurality of locking grooves are formed on the transport beam near the exit of the long and narrow section. The locking bolt penetrates through the locking ring and is threadedly connected with the locking grooves.

[0020] By adopting the above technical solution, after the electric hoist lifts a large object, according to the length of the large object, the connecting rope is adjusted to tighten the transport beams through the connecting rope. Then the connecting rope is fixed by threading the locking bolt through the locking ring and the locking grooves, so as to facilitate the synchronous movement of the transport beams.

[0021] Preferably, a plurality of detachable support columns are arranged at the bottom of the support frame.

[0022] By adopting the above technical solution, the support columns at the bottom of the support frame are installed in the long and narrow section. The support columns play a role in supporting the support frame, reducing the situation that the support frame breaks due to excessive force.

[0023] In summary, the present application includes at least one of the following beneficial technical effects:

[0024] 1. By setting up a support frame, a transport trough, a transport beam, a synchronization component, an electric hoist and a mounting component, it is convenient to transport large objects within a long and narrow section, keeping the ground clear and maintaining the construction progress;

[0025] 2. By setting up a connecting rope, a towing rope, a synchronization roller and a synchronization motor, the transport beam moves synchronously to drive the large object to move;

Detailed Description of the Embodiment

[0034] The following further describes the present application in detail with reference to the attached Figures 1-6 drawings.

[0035] An embodiment of the present application discloses a large object transport device for container ship construction. Refer to Figures 1 to 4, including a set of support frames 1, one end of the support frame 1 is located at the inlet of the long and narrow section, and the other end of the support frame 1 is located in the long and narrow section. Installation components 5 are installed at both ends of the support frame 1, and the installation components 5 are used to install the support frame 1 in the long and narrow section. Transportation grooves 21 are formed on the opposite surfaces of the support frame 1 along the length direction of the support frame 1, and a set of transportation beams 2 are slidably arranged between the transportation grooves 21. One end of the transportation beam 2 is slidably arranged in one of the transportation grooves 21, and the other end of the transportation beam 2 is slidably arranged in the other transportation groove 21. Pulleys 22 are rotatably arranged at both ends of the transportation beam 2, and the pulleys 22 are rollingly arranged in the transportation grooves 21. A synchronization component 3 is jointly arranged in the transportation grooves 21, and the synchronization component 3 is used to drive the transportation beam 2 to move synchronously. An electric hoist 4 is installed at the bottom of the transportation beam 2, and the electric hoist 4 is used to lift large objects. The support frame 1 is installed in the long and narrow section through the installation component 5, so that one end of the support frame 1 is located at the inlet of the long and narrow section, and the other end of the support frame 1 is located at the outlet of the long and narrow section. When it is necessary to transport large objects in the long and narrow section, the large objects are lifted by the electric hoist 4 at the inlet of the long and narrow section. One electric hoist 4 lifts one end of the large object, and the other electric hoist 4 lifts the other end of the large object. Then the synchronization component 3 is started, and the synchronization component 3 drives the transportation beam 2 to move synchronously. The pulleys 22 at both ends of the transportation beam 2 roll in the transportation grooves 21, reducing the friction between the transportation beam 2 and the inner wall of the transportation groove 21, facilitating the transportation beam 2 to drive the large object to move. Furthermore, the large object is transported in the long and narrow section, keeping the ground unobstructed and maintaining the construction progress.

[0036] In order to install the support frame 1 in the long and narrow section, referring to Figure 1 and Figure 6 , the installation component 5 includes a set of mounting plates 51, and a number of connection holes 512 are formed on the mounting plates 51. One of the mounting plates 51 is connected to the inlet of the long and narrow section through bolts penetrating the connection holes 512, and the other mounting plate 51 is connected to the outlet of the long and narrow section through bolts penetrating the connection holes 512. Mounting holes 511 are formed on the mounting plates 51 along the length direction of the support frame 1, and the support frame 1 is inserted into the mounting holes 511. A number of positioning grooves 82 are formed on the inner wall of the mounting holes 511, and positioning bolts 81 are arranged in the positioning grooves 82. A number of positioning holes 8 are formed on the support frame 1, and the positioning bolts 81 penetrate the positioning holes 8 and are threadedly connected to the positioning grooves 82. A number of support columns 11 are detachably arranged at the bottom of the support frame 1. According to the length and width of the long and narrow section, the position of the support frame 1 in the mounting holes 511 is adjusted. After the adjustment is completed, the positioning bolts 81 penetrate the positioning holes 8 and are threadedly connected to the positioning grooves 82, so that the support frame 1 is connected to the mounting plate 51. The support columns 11 at the bottom of the support frame 1 are installed in the long and narrow section, and the support columns 11 play a supporting role for the support frame 1, reducing the situation that the support frame 1 breaks due to excessive stress.

[0037] In order to make the transportation beam 2 move synchronously to drive the large object to move, referring to Figures 1 to 3, the synchronization component 3 includes a set of guide rods 35, a connecting rope 31, a towing rope 32, a synchronization roller 33, and a synchronization motor 34. One of the guide rods 35 is installed in one of the transport grooves 21 along the length direction of the support frame 1, and the other guide rod 35 is installed in the other transport groove 21 along the length direction of the support frame 1. The transport beam 2 is sleeved on the guide rod 35, and the outer wall of the transport beam 2 is in mutual contact with the guide rod 35. The synchronization roller 33 and the synchronization motor 34 are both installed on the mounting plate 51 near the exit end of the narrow section. The synchronization roller 33 is rotatably connected to the mounting plate 51, and the drive shaft of the synchronization motor 34 is welded to one end of the synchronization roller 33. One end of the towing rope 32 is wound around the synchronization roller 33 and bolted to the synchronization roller 33, and the other end of the towing rope 32 is bolted to the center of the side wall of the transport beam 2 near the exit end of the narrow section. One end of the connecting rope 31 is connected to the top of one of the transport beams 2, and the other end of the connecting rope 31 is connected to the top of the other transport beam 2. When the synchronization motor 34 is started, the synchronization motor 34 drives the synchronization roller 33 to rotate, and the rotation of the synchronization roller 33 drives the towing rope 32 to be wound around the synchronization roller 33. Further, the towing rope 32 pulls the transport beam 2 near the exit end of the narrow section to move, and the movement of the transport beam 2 near the exit end of the narrow section pulls the connecting rope 31 to move, and the connecting rope 31 drives the transport beam 2 near the entrance end of the narrow section to move, so that the transport beam 2 moves along the direction set by the guide rod 35, and further the synchronous movement of the transport beam 2 drives the large object to move.

[0038] To move the transport beam 2 to the entrance end of the narrow section, refer to Figure 5 , the reset roller 6 and the reset motor 62 are both installed on the side wall of the mounting plate 51 near the entrance end of the narrow section. The reset roller 6 is rotatably connected to the mounting plate 51, and the drive shaft of the reset motor 62 is welded to one end of the reset roller 6. A reset rope 61 is wound around the reset roller 6, and the end of the reset rope 61 away from the reset roller 6 is bolted to the transport beam 2 near the exit end of the narrow section. During the transportation of the large object, the reset motor 62 rotates forward to apply a reverse traction force to the transport beam 2 on the side close to the reset roller 61 to reduce the inertial movement of the transport beam 2. After the transportation of the large object is completed, the synchronization motor 34 stops, and the reset motor 62 is started. The reset motor 62 drives the reset roller 6 to rotate, and the rotation of the reset roller 6 drives the reset rope 61 to be wound around the reset roller 6. Further, the reset rope 61 pulls the transport beam 2 near the entrance end of the narrow section to move, and the movement of the transport beam 2 near the entrance end of the narrow section pulls the connecting rope 31 to move, and the connecting rope 31 drives the transport beam 2 near the exit end of the narrow section to move, and further the transport beam 2 moves to the entrance end of the narrow section.

[0039] To facilitate the synchronous movement of the transport beam 2, refer to Figure 2, connection seats 23 are installed on the top of the transportation beams 2. One end of the connection rope 31 passes through the connection seat 23 near the entrance of the narrow section and is bolted to the connection seat 23. The other end of the connection rope 31 passes through the connection seat 23 near the exit of the narrow section and a locking ring 7 is installed on the end wall. A locking bolt 71 is arranged inside the locking ring 7. A number of locking grooves 72 are formed on the top wall of the transportation beam 2 near the exit of the narrow section. The locking bolt 71 passes through the locking ring 7 and is threadedly connected to the locking groove 72. After the electric hoist 4 lifts a large object, according to the length of the large object, the connection rope 31 is adjusted to tighten the transportation beams 2 through the connection rope 31. Then, the connection rope 31 is fixed by threading the locking bolt 71 through the locking ring 7 and threadedly connecting it to the locking groove 72, thereby facilitating the synchronous movement of the transportation beams 2.

[0040] The implementation principle of a large object transportation device for container ship construction in an embodiment of the present application is as follows: One mounting plate 51 is installed at one end of the entrance of the narrow section, and the other mounting plate 51 is installed at one end of the exit of the narrow section. Both ends of the support frame 1 are inserted into the mounting plate 51 and connected to the mounting plate 51. When it is necessary to transport a large object in the narrow section, the large object is lifted by the electric hoist 4 at the entrance of the narrow section. One electric hoist 4 lifts one end of the large object, and the other electric hoist 4 lifts the other end of the large object. Then, the synchronous motor 34 is started, and the synchronous motor 34 drives the synchronous roller 33 to rotate. The synchronous roller 33 rotates to drive the traction rope 32 to be wound around the synchronous roller 33. Further, the traction rope 32 pulls the transportation beam 2 near the exit of the narrow section to move. The movement of the transportation beam 2 near the exit of the narrow section pulls the connection rope 31 to move, and the connection rope 31 drives the transportation beam 2 near the entrance of the narrow section to move, so that the transportation beam 2 moves along the direction set by the guide rod 35. Further, the pulleys 22 at both ends of the transportation beam 2 roll in the transportation groove 21. Thus, the large object is transported in the narrow section, keeping the ground unobstructed and maintaining the construction progress.

[0041] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited accordingly. Therefore, all equivalent changes made according to the structure, shape, and principle of the present application should be covered within the protection scope of the present application.
