Description

Technical Field

[0001] The invention relates to the technical field of transport roll-off operation, and in particular to a berthing roll-off system and method for a ship unloader. Background Art

[0002] Ship unloaders are usually transported by transport ships to the user's dock for delivery. Ship unloader roll-on / roll-off refers to the process of transferring the entire ship unloader from the transport ship to the dock or other designated location by roll-on / roll-off. With the development of large-scale and efficient ship unloaders, the requirements for ship unloader roll-on / roll-off technology are also increasing. It is necessary to continuously improve and innovate roll-on / roll-off devices and processes to improve the transportation efficiency and safety of ship unloaders.

[0003] The traditional roll-on / roll-off method of ship unloaders usually uses a ship unloader roll-off steering device to complete the roll-on / roll-off operation of the ship unloader. During the use of the ship unloader roll-on / roll-off steering device, the ship unloader needs to be jacked up, which has high requirements on the load points of the dock and the jacking points, and the jacking position is limited. At the same time, the layout requirements of the steering wheel group of the ship unloader are also high. The entire jacking and steering process of the ship unloader is time-consuming and risky, and there is a defect that the ship unloader is difficult to unload; at the same time, the ship unloader will inevitably interfere with the facilities on the dock during the unloading process, and it is necessary to dismantle the new pier belt corridor and other facilities at the port dock; and a large number of box-type rails need to be laid on the dock, and the parallelism of the rails needs to be ensured. The docking position of the rails needs to be welded, and the number of rails is four. Therefore, the traditional roll-on / roll-off method of ship unloaders has the defect that the ship unloader is difficult to unload. Summary of the invention

[0004] In order to solve the problem that the existing roll-on / roll-off mode of a ship unloader is difficult for the ship unloader to unload the ship, the present invention provides a ship unloader berthing and rolling-off system and method, which facilitates the ship unloader to roll-off from the transport ship by changing the traditional roll-on / roll-off form of jacking, turning and dropping on the rails and the conventional berthing form of the transport ship, reduces the risk of the ship unloader unloading and improves the work efficiency of the ship unloader rolling-off operation.

[0005] In order to achieve the above-mentioned purpose, the technical solution of the present invention is: a ship unloader berthing and rolling unloading system, comprising a berthing dock, a ship unloader and a transport ship for transporting the ship unloader, wherein the berthing dock is provided with dock tracks, and the transport ship is provided with deck tracks for carrying the ship unloader. The transport ship carries and transports the ship unloader via the deck tracks, and the deck tracks enable the ship unloader to perform roll-on / roll-off operations.

[0006] It also includes a rigid chord guard mechanism and a rolling mechanism, wherein the rigid chord guard mechanism is arranged at the edge of the transport ship; a traction component located outside the rolling mechanism is arranged on one side of the transport ship, and the rigid chord guard mechanism is used to prevent the transport ship from colliding with the berthing pier when berthing at the berthing pier.

[0007] The roll-off mechanism includes a deck bridgehead, a rail sleeper, a shore bridgehead, a ramp track and a rigid bridge. The deck bridgehead is fixed on the transport ship and corresponds to the deck track; the rail sleeper is fixed on the berthing wharf, the shore bridgehead is set on the top of the rail sleeper, one end of the rigid bridgehead is hinged to the shore bridgehead, and the other end is freely overlapped with the deck bridgehead, one end of the ramp track is located on the wharf track, and the other end of the ramp track is located on the rail sleeper and connected to the shore bridgehead. Through the mutual splicing system of the deck bridgehead, the rigid bridgehead, the shore bridgehead and the ramp track, the ship unloader can be directly rolled onto the wharf track, avoiding the construction risk of lifting, reversing and dropping the track.

[0008] Furthermore, the rigid chord guard mechanism includes a bracket, a steel wire rope and a rigid chord guard, the bracket is fixedly arranged on the transport ship, a lug plate is fixedly arranged at the bottom of the horizontal end of the bracket, the two ends of the steel wire rope are respectively connected to the lug plate and the rigid chord guard, and the rigid chord guard is located between the transport ship and the berthing pier. The rigid chord guard is suspended on the outside of the transport ship by the steel wire rope, so as to avoid the transport ship from colliding with the berthing pier when the transport ship is berthed at the berthing pier.

[0009] Furthermore, the number of the rolling mechanism and the traction assembly is two, one of the traction assemblies includes a mooring anchor and a plurality of cables, the two ends of the cables are respectively connected to the mooring anchor and the transport ship; the other traction assembly includes a mooring pile and a plurality of cables, the two ends of the cables are respectively connected to the mooring pile and the transport ship. The two traction assemblies can achieve the effect of fixing the transport ship with cables on both sides, which can effectively stabilize the transport ship and can also release the restrictions on the transport ship at any time to adjust the position of the transport ship.

[0010] Furthermore, the top of the deck bridgehead is tilted downward in a direction away from the rigid bridge, a deck bridgehead track is arranged on the top of the deck bridgehead, a lap plate is fixedly arranged at one end of the deck bridgehead, and a first support bar and a second support bar are fixedly arranged on the top of the lap plate; a hinged seat is arranged at one end of the shore bridgehead, and a shore bridgehead track is arranged on the top of the shore bridgehead. The purpose of the top of the deck bridgehead tilting downward is to make the deck bridgehead track in an inclined state, so as to facilitate the ship unloader to move across the deck bridgehead to the rigid bridge via the deck bridgehead track.

[0011] Furthermore, the rigid bridge includes a bridge body and a bridge track. The thickness of the bridge body gradually increases from left to right and from right to left. The bridge track is fixedly arranged on the top of the bridge body, and the bridge track corresponds to the deck bridgehead track and the shore bridgehead track. A hinge plate is arranged at the bottom of one end of the bridge body, and the hinge plate is hinged to the hinge seat. The other end of the bridge body is located at the top of the first support bar and the second support bar. The rigid bridge is hinged to the shore bridgehead through the cooperation of the hinge plate and the hinge seat. The purpose is that as the position of the ship unloader moves, the draft of the transport ship changes at any time, so that the rigid bridge can effectively cooperate with the adjustment of the up and down amplitude of the ship unloader during rolling and unloading, and always keep the track on the transport ship and the track on the shore level to avoid affecting the rolling and unloading operation of the ship unloader.

[0012] Furthermore, the ramp track includes a support plate and an inclined track, the inclined track is fixedly arranged on the top of the support plate, the length of the inclined track is greater than the length of the support plate, the height of the inclined track gradually decreases in the direction away from the bridgehead on the shore, the top of one end of the inclined track is an arc-shaped structure, and the angle between the inclined track and the dock track is not greater than 3°; the bottom of the support plate is symmetrically provided with fixed blocks located on both sides of the dock track, and a movable wedge is arranged between the fixed block and the dock track. By clamping the movable wedge between the fixed block and the dock track, the ramp track is clamped to avoid the risk of slipping and swinging of the ramp track when the ship unloader is rolling and unloading.

[0013] A rolling unloading method based on the above-mentioned ship unloader berthing rolling unloading system comprises the following steps: Step 1: Before the transport ship berths at the berthing pier, two deck bridgeheads corresponding to the deck rails are fixed side by side on the top of the transport ship, and rigid string guard mechanisms are arranged side by side at the edge of one side of the transport ship berthed at the berthing pier.

[0014] Step 2: Fix two sleepers side by side on the berthing terminal, install shore bridgeheads on the top of the two sleepers respectively, place one end of the ramp track on the top of the sleepers and connect it to the shore bridgehead to align the inclined track of the ramp track with the terminal track and the shore bridgehead track.

[0015] Step 3: berth the transport ship at a berthing pier, and make the rigid guardrail of the rigid guardrail mechanism berth at the berthing pier.

[0016] Step 4: Adjust the position of the transport ship and make the deck bridgehead correspond to the shore bridgehead; then fix the transport ship by double-sided cable, and use cables to cooperate with mooring anchors and mooring piles to secure the transport ship with cables.

[0017] Step 5: hinge one end of the rigid bridge to the shore bridgehead and freely overlap the other end to the deck bridgehead, so that the bridge track is aligned with the shore bridgehead track and the deck bridgehead track.

[0018] Step 6: Then use the traction equipment to tow the ship unloader, and make the ship unloader move to the dock track through the deck bridge head, rigid bridge, shore bridge head and ramp track in sequence.

[0019] Step 7: After the unloading operation of the ship unloader is completed, the cable is released and the position of the transport ship is adjusted to carry out the unloading operation of the next ship unloader.

[0020] Furthermore, in step 1, fixing the rigid guardrail mechanism on the transport ship includes: fixing the vertical end of the bracket on the top of the transport ship, connecting one end of the steel wire rope to the ear plate, and connecting the other end of the steel wire rope to the rigid guardrail, so that when the transport ship is berthed at the berthing pier, the rigid guardrail is located between the transport ship and the berthing pier.

[0021] Furthermore, in step 2, the sleepers are fixed by anchor bolts at the original stop position of the unloading ship crane trolley on the berthing terminal; after the slope track is put into place, a movable wedge is embedded between the fixed block of the terminal track and the slope track to clamp the slope track.

[0022] Furthermore, in step 5, the hinge seat of the shore bridgehead is hinged to the hinge plate of the rigid bridge through a pin, and one end of the rigid bridge is located on top of the first support bar and the second support bar of the deck bridgehead.

[0023] Through the above technical solution, the beneficial effects of the present invention are: 1. The reliability and practicality of the present invention are strong. By changing the traditional jacking, turning and dropping rail roll-on and roll-off form and the conventional berthing form of the transport ship, the demolition of the newly built pier belt corridor and other facilities at the berthing terminal is avoided; and the effect of facilitating the unloading of the ship unloader from the transport ship is achieved, and the problem of the difficulty of unloading the existing ship unloader is solved. Through the mutual splicing system of the deck bridge head, the rigid bridge, the shore bridge head and the ramp track, the ship unloader can be directly rolled onto the dock track, avoiding the construction risk of jacking, turning and dropping rails, and reducing the risk of the ship unloader rolling operation.

[0024] 2. The present invention can effectively save manpower and material resources in the unloading operation of the ship unloader, and save a large number of tracks for the unloading ship unloader. Conventional ship unloaders usually use four tracks to go ashore, and the track laying length is the entire width of the berthing terminal. The present invention only needs a rigid bridge and a ramp track to connect to the deck track on the transport ship to roll the ship ashore, saving the manufacturing cost of the ship unloader rolling track.

[0025] 3. The rigid guardrail mechanism of the present invention suspends the rigid guardrail on the outside of the transport ship through the cooperation of the steel wire rope and the ear plate, thereby achieving the effect of preventing the transport ship from colliding with the berthing pier when the transport ship is berthed at the berthing pier.

[0026] 4. The present invention achieves the effect of fixing the transport ship with cables on both sides through two traction components, which can effectively stabilize the transport ship and prevent the transport ship from moving during the rolling and unloading operation of the ship unloader, thereby preventing the transport ship from affecting the rolling and unloading operation of the ship unloader; at the same time, the restrictions on the transport ship can be lifted at any time to adjust the position of the transport ship, and is suitable for the application of rolling and unloading operations of two ship unloaders on the same transport ship.

[0027] 5. The rigid bridge of the present invention is hinged with the shore bridgehead and freely overlapped with the deck bridgehead. Its purpose is that as the position of the ship unloader moves, the draft of the transport ship is in a state of changing at any time, so that the rigid bridge can effectively cooperate with the adjustment of the up and down amplitude of the ship unloader during rolling and unloading, and control the horizontality of the track on the transport ship and the track on the shore; the end of the rigid bridge corresponding to the deck bridgehead is in a free state, so as to achieve the effect of being able to adapt to the adjustment of the transport ship at any time without getting stuck.

[0028] 6. The slope track of the present invention is supported by sleepers and is in an inclined state due to the action of the sleepers, and the top of the inclined track is inclined to achieve the effect of facilitating the towing of the ship unloader to the dock track; the top of one end of the inclined track is an arc-shaped structure, and the angle between the inclined track and the dock track is not greater than 3°, so that the ship unloader can cross the slope track and move to the dock track; at the same time, by clamping the movable wedge block between the fixed block and the dock track, the slope track is clamped to avoid the risk of slipping and swinging of the slope track when the ship unloader is rolling and unloading.

A lap plate 701 is fixedly provided at one end of the deck bridgehead 7, and a first support bar 702 and a second support bar 703 are fixedly provided on the top of the lap plate 701; an articulated seat 11 is provided at one end of the shore bridgehead 10, and a shore bridgehead track is provided on the top of the shore bridgehead 10. In this embodiment, the purpose of the inclined setting of the top of the deck bridgehead 7 is to make the deck bridgehead track 704 in an inclined state so that the deck bridgehead track 704 is aligned with the deck track 3, and at the same time, the ship unloader 2 moves to the deck bridgehead track 704, and crosses the deck bridgehead 7 through the deck bridgehead track 704 to move to the rigid bridge; the rigid bridge is freely overlapped by the lap plate 701 and the first support bar 702 and the second support bar 703 on the top of the lap plate 701, so that the bridge track 17 corresponds to the deck bridgehead track 704; at the same time, it is convenient for the rigid bridge to be located at one end of the lap plate 701 to adjust the up and down amplitude as the draft depth of the transport ship 1 changes, so as to facilitate the ship unloader 2 to move to the bridge track 17 through the deck bridgehead track 704; wherein the top of the first support bar 702 is an arc-shaped structure, and the second support bar 703 is located on the inner side of the second support bar 702.

[0039] The rigid bridge includes a bridge body 16 and a bridge track 17. The thickness of the bridge body 16 gradually increases from left to right and from right to left. The bridge track 17 is fixedly arranged on the top of the bridge body 16, and the bridge track 17 corresponds to the deck bridge head track 704 and the shore bridge head track; a hinge plate 18 is arranged at the bottom of one end of the bridge body 16, and the hinge plate 18 is hinged to the hinge seat 11. The other end of the bridge body 16 is located at the top of the first support bar 702 and the second support bar 703. In the present embodiment, the thickness of the bridge body 16 gradually increases from left to right and from right to left, so that the bridge track 17 tilts from the middle to both ends, thereby facilitating the ship unloader 2 to roll over the rigid bridge to the shore bridgehead 10; the hinged plate 18 is hinged to the hinged seat 11 through a pin shaft, so that the rigid bridge can rotate relative to the shore bridgehead 10, thereby achieving the effect that the rigid bridge can effectively cooperate with the ship unloader 2 to adjust its up and down amplitude when rolling.

[0040] The slope track includes a support plate 12 and an inclined track 13, wherein the inclined track 13 is fixedly arranged on the top of the support plate 12, the length of the inclined track 13 is greater than the length of the support plate 12, the height of the inclined track 13 gradually decreases in the direction away from the shore bridgehead 10, the top of one end of the inclined track 13 is an arc-shaped structure, and the angle between the inclined track 13 and the dock track 19 is not greater than 3°; the bottom of the support plate 12 is symmetrically provided with fixed blocks 14 located on both sides of the dock track 19, and a movable wedge block 15 is arranged between the fixed block 14 and the dock track 19.

The purpose of the arc-shaped structure at the top of the inclined track 13 near the dock track 19 is to facilitate the ship unloader 2 to roll onto the dock track 19 and maintain the stability of the ship unloader 2 during rolling. The purpose of the angle between the inclined track 13 and the dock track 19 being no greater than 3° is to avoid a large height difference between the two, thereby ensuring the stability of the ship unloader 2 rolling from the inclined track 13 to the dock track 19. The fixed block 14 is welded and fixed to the bottom of the support plate 12. After the inclined track is put in place, the movable wedge block 15 is clamped between the fixed block 14 and the dock track 19 to clamp the inclined track, thereby avoiding the risk of non-directionality such as slippage and swing of the inclined track when the ship unloader 2 is rolling.

[0042] In this embodiment, lifting ears are installed on both sides of the shore bridgehead 10, the rigid bridge, the deck bridgehead 7 and the slope track, and the shore bridgehead 10, the rigid bridge, the deck bridgehead 7 and the slope track are lifted by the lifting ears.

[0043] A rolling unloading method based on the above-mentioned ship unloader berthing rolling unloading system comprises the following steps: Step 1: Before the transport ship 1 berths at the berthing pier, two deck bridgeheads 7 corresponding to the deck rails 3 are fixed side by side on the top of the transport ship 1, the deck bridgehead rail 704 is aligned with the deck rail 3, and a rigid string guard mechanism is arranged side by side at the edge of one side where the transport ship 1 is berthed at the berthing pier.

[0045] Step 2: Fix two sleepers 9 side by side on the berthing terminal, install shore bridgeheads 10 on the top of the two sleepers 9 respectively, place one end of the slope track on the top of the sleepers 9 and connect it to the shore bridgehead 10, so as to align the inclined track 13 of the slope track with the terminal track 19 and the shore bridgehead track.

[0046] The sleepers 9 are fixed by anchor bolts at the original stop position of the unloading ship machine trolley on the berthing terminal; after the slope track is put in place, the movable wedge 15 is embedded between the dock track 19 and the fixed block 14 of the slope track to clamp the slope track.

[0047] Step 3: berth the transport ship 1 at a berthing pier, and make the rigid guardrail 6 of the rigid guardrail mechanism berth at the berthing pier.

[0048] Step 4: Adjust the position of the transport ship 1 and make the deck bridgehead 7 correspond to the shore bridgehead 10; then fix the transport ship 1 by double-sided cable, and use the cable 8 to cooperate with the mooring anchor and the mooring pile to fasten the transport ship 1 with cable.
