Description

Dynamic floating bridge suitable for island reef and wharf

Technical Field

The invention relates to the technical field of wharf pontoon construction, in particular to a dynamic pontoon suitable for an island reef and a wharf.

Background

The world economy has stepped into the global era, and the maritime trade of various countries is frequent. Ocean-going large wheels have the characteristics of large tonnage, large draught and the like, are difficult to moor near island reefs or shallow water wharfs, and further cause the loading and unloading of goods to be a great problem. In this context, shore-side monuments are used to establish a logistics pathway between the reef or shallow water terminal and the ocean-going vessel.

In the prior art, the shoreside building is mainly divided into two types, one is a trestle and the other is a dynamic pontoon. The trestle is a fixed building built in an island reef or a wharf shallow water area, and in actual construction, the digging and building workload is huge, so that the construction cost is high, the trestle is easily submerged by seawater due to the influence of flood tide, and the normal loading and unloading of goods can be influenced. For dynamic pontoons, a number of design solutions have emerged in the industry. For example, chinese patent CN205934690U discloses a novel floating bridge, which includes: the floating bridge unit I, the floating bridge unit II, the elastic connecting block and the bolt assembly; the end side face of the first floating bridge unit is provided with a first connecting groove, and a first mounting through hole group is arranged on the outer wall perpendicular to the first connecting groove; the end side face of the second floating bridge unit is provided with a second connecting groove, and a second mounting through hole group is arranged on the outer wall perpendicular to the second connecting groove; the elastic connecting block is also provided with a third mounting through hole group and a fourth mounting through hole group; the first floating bridge unit and the second floating bridge unit can be connected with the elastic connecting block through corresponding connecting grooves and holes; and the elastic connecting block is used as a transition connecting piece to connect the first floating bridge unit and the second floating bridge unit. For another example, chinese patent CN217324943U discloses a floating bridge convenient to splice, which includes a plurality of floating bridge plate bodies, where the floating bridge plate bodies are provided with a connection structure, the connection structure includes a rotation rod, a first gear, a second gear, a threaded rod, a threaded groove, and a driving rod, the inner wall of each floating bridge plate body is rotatably connected to the rotation rod, two first gears are fixed on the rotation rod, the inner wall of each floating bridge plate body is rotatably sleeved with two second gears, the two first gears are respectively engaged with the two second gears, the inner wall of each floating bridge plate body is provided with two threaded grooves, the two threaded rods on two adjacent floating bridge plate bodies are respectively in threaded connection with the two threaded grooves, the rotation rod is slidably connected to the driving rod, and the driving rod can extend to the outer side of the floating bridge plate body. Although the two technical schemes can be conveniently and quickly used for establishing the logistics channel between the island, the wharf and the ocean large ship, the floating bridge unit or the floating bridge plate body is impacted by waves and is liable to surge and float, so that a loading and unloading worker cannot stand stably, the loading and unloading efficiency of goods is finally influenced, and the work safety risk is high. Thus, a skilled person is urgently needed to solve the above problems.

As a further improvement of the technical scheme disclosed by the invention, the damping unit is composed of at least 1 hydraulic damper connected between the floating seat and the bearing base.

Compared with a dynamic floating bridge with a traditional design structure, the floating bridge module is matched with the traction unit.

Detailed Description

In the description of the present invention, it should be understood that the terms "front", "back", "upper", "lower", "left", "right", and the like indicate orientations or positional relationships based on orientations or positional relationships shown in the drawings, and are only for convenience of description and simplicity of description, but do not indicate or imply that the device or element referred to must have a particular orientation, be constructed in a particular orientation, and be operated, and thus, should not be construed as limiting the present invention.

The dynamic floating bridge is built on the reef and the shallow water area of the wharf to assist the ocean-going large ship to carry out cargo loading and unloading operations.

The disclosure of the present invention will be further described in detail with reference to the following specific examples, and fig. 1 and 2 together show a schematic structural diagram of a first embodiment of the dynamic pontoon for an island reef and a dock according to the present invention, and it can be understood that the dynamic pontoon mainly comprises a pontoon module 1 and a connection unit 2. Wherein, the multiple floating bridge modules 1 are arranged in a linear manner, and are connected end to end by the connecting unit 2, and a cargo circulation channel is concomitantly erected among the island, the wharf and the ocean-going large ship. The linking unit 2 is composed of a plurality of woven nets 21 connected between two adjacent bearing bases at the same time. As shown in fig. 3, the flying bridge module 1 includes a carrying base 11, a floating seat 12, and a drawing unit 13. The loading base 11 is used for loading pedestrians or cargoes. The floating base 12 is used for providing support for the bearing base 11 and floating in seawater. The pulling unit 13 serves as a connecting transition between the pontoon 12 and the seabed. In the time period of seawater rising tide and falling tide, the pulling force applied to the floating seat 12 by the pulling unit 13 changes adaptively, the distance value d between the bearing base 11 and the sea level is kept at a constant value, and the bearing base 11 is always kept at a level state relative to the cargo outlet of the ocean-going tug.

In practical application, the dynamic floating bridge is suitable for reefs and docks, and has the following beneficial technical effects:

1) The pontoon module 1 is provided with a traction unit 13. In practical application, the traction unit 13 always applies traction force to the floating seat 12, so that on one hand, the phenomenon that the dynamic floating bridge deviates from the original design position when being impacted by waves and cannot be accurately butted with the ocean-going large ship is avoided, and the dynamic floating bridge is ensured to always keep good position stability in practical application;

2) Effectively reducing the self surge floating amplitude of the floating bridge module 1 when the floating bridge module is impacted by waves, thereby being beneficial to a loading and unloading worker to stably stand on the floating bridge module, further ensuring the working safety of the loading and unloading worker, and greatly improving the loading and unloading efficiency of goods.

3) Along with different time stages of the rise tide and the fall tide of the seawater, the pulling force applied by the pulling unit 13 to the floating seat 12 changes adaptively, the bearing base platform 11 can keep consistent with the sinking and floating movement of the ocean-going giant wheel, and further the accurate butt joint state of the bearing base platform 11 and the ocean-going giant wheel is ensured to be kept all the time in practical application, so that the circulation of goods and personnel is facilitated.

It is known that, according to common design knowledge, the pulling unit 13 can take various design structures to achieve the pulling operation of the floating seat 12, however, an embodiment is proposed herein that has a simple design structure, is easy to construct, and can ensure that the floating seat 12 is stably pulled, as follows: as can be seen from fig. 1 and 3, for a single set of the pontoon module 1, the pulling unit 13 is composed of two sets of pulling sub-units 131 which cooperate with each other to pull the pontoon 12 obliquely in opposite directions. As shown in fig. 3, the pulling subunit 131 is mainly composed of an anchorage 1311, a mooring line 1312, and a hoisting power 1313. Among other things, anchor 1311 is used to tie up anchor lines 1312, which are buried deep and fixed to the seabed. A hoisting power section 1313 for winding up mooring lines 1312 is mounted in pontoon 12. In practical application, in the flood tide stage, the height of the sea wave exceeds 1.25m, the ocean current giant ship generates upward floating movement, meanwhile, the buoyancy of the seawater borne by the floating seat 12 is increased, the hoisting power part 1313 is started, the two anchor ropes 1312 are simultaneously loosened, and the floating seat 12 floats upwards due to the reduction of the pulling force borne by the floating seat; in the stage of falling tide, the ocean-going large vessel descends, and at the same time, the buoyancy of the seawater applied to the floating seat 12 is reduced, the hoisting power part 1313 is started reversely, the two anchor ropes 1312 are tightened at the same time, and the position of the floating seat 12 is lowered due to the increase of the pulling force applied to the floating seat. Therefore, on one hand, the floating bridge module 1 is always kept in a compressed state in the process of carrying out the cargo loading, and the position deviation phenomenon caused by high-strength surge impact is avoided; on the other hand, because the bearing base 11 is subjected to different pulling forces at different stages, it can be always kept in a flush state with the unloading port of the ocean-going vessel, thereby avoiding the occurrence of inconvenient cargo loading and unloading or inconvenient passage of the loading and unloading workers due to the height difference.

As shown in fig. 4, as a further refinement of the above technical solution, the hoisting power part 1313 includes a rotary motor 13131, a force transmission mechanism 13132, a first reel 13133, and a second reel 13134. The rotary motor 13131 is detachably fixed to the pontoon 12 as a unit, and is assisted by a force transmission mechanism 13132 to synchronously drive the first and second reels 13133, 13134 to perform a circumferential rotary motion, so that the traction on the pontoon 12 is tightened or loosened about the two anchor lines 1312 wound on the first and second reels 13133, 13134, respectively. As shown in fig. 5, the force transmission mechanism 13132 includes a first sprocket 131321, a second sprocket 131322, a third sprocket 131323, a chain 131324, a first vertical transmission shaft 131325, a second vertical transmission shaft 131326, a first horizontal transmission shaft 131327, a second horizontal transmission shaft 131328, a first bevel gear 131329, a second bevel gear 1313210, a third bevel gear 1313211, and a fourth bevel gear 1313212. The first sprocket 131321 is driven by a rotary motor 13131. The first vertical transmission shaft 131325 and the second vertical transmission shaft 131326 are symmetrically disposed at two sides of the rotating electrical machine 13131, and are sleeved and fixed by the second sprocket 131322 and the third sprocket 131323 in a one-to-one correspondence. Chain 131324 simultaneously engages first sprocket 131321, second sprocket 131322, and third sprocket 131323. The first bevel gear 131329 is sleeved and fixed on the first horizontal transmission shaft 131327, and the second bevel gear 1313210 engaged with the first bevel gear 131329 is fixed on the lower end of the first vertical transmission shaft 131325. The third bevel gear 1313211 is sleeved on and fixed to the second horizontal transmission shaft 131328, and the fourth bevel gear 1313212, which is engaged with the third bevel gear 1313211, is fixed to the lower end of the second vertical transmission shaft 131326. By adopting the technical scheme, on one hand, the force transmission mechanism 13132 can distribute the rotating torque of the rotating motor 13131 to the first winding drum 13133 and the second winding drum 13134 at the same time, so that the tightening process and the loosening process of the two anchor ropes 1312 are always kept synchronous, and the phenomenon that the floating bridge module 1 is inclined due to unbalanced traction force is effectively avoided; on the other hand, the force transmission mechanism 13132 disclosed in this embodiment has high transmission efficiency and smooth transmission, and generates relatively small operating noise.

In the actual operation stage, it is found that when the pontoon module 1 is partially submerged, the rotary motor 13131 is very likely to be "burned" due to infiltration of seawater, and the first sprocket 131321, the second sprocket 131322, the third sprocket 131323, and the chain 131324 cannot mesh correctly due to influence of impurities or corrosion, and in view of this, as a further optimization of the above technical solution, a protective cover is further installed on the pontoon 12 directly below the supporting base 11, so as to simultaneously achieve water-sheltering protection for the hoisting power part 1313 (which is illustrated in fig. 1 and 3, but not shown by the drawing numbers).

Furthermore, as shown in fig. 1, it can be clearly seen that the dynamic pontoon for the reef and the wharf is further provided with the buffer unit 3 to prevent the premature damage of the two adjacent pontoon 12 caused by the rigid impact force. As shown in fig. 6, the cushion unit 3 is preferably composed of a plurality of elastic bodies 31 (such as rubber pads with a thickness greater than 8mm and polyurethane foam with a thickness greater than 20 mm) sandwiched between the floating seats 12 and elastically deformed adaptively according to the pressure.

As can also be clearly seen from fig. 3, the floating bridge module 1 is further added with a support assembly 14 and a buoyancy plate 15. The floating seat 12 is supported by the supporting component 14 to realize the supporting of the bearing base 11. The support assembly 14 is mainly composed of a first slide lever 141, a second slide lever 142, a third slide lever 143, a fourth slide lever 144, a first linear bearing 145, a second linear bearing 146, a third linear bearing 147, and a fourth linear bearing 148. The first sliding rod 141, the second sliding rod 142, the third sliding rod 143 and the fourth sliding rod 144 are all vertically inserted into the floating seat 12 in a free sliding manner. A first linear bearing 145 adapted to the first sliding rod 141, a second linear bearing 146 adapted to the second sliding rod 142, a third linear bearing 147 adapted to the third sliding rod 143, and a fourth linear bearing 148 adapted to the fourth sliding rod 144 are embedded and fixed in the floating seat 12. The buoyancy plate 15 is attached to and fixed to the bottom wall of the supporting base 11. In the stage of seawater tide rising time, the wave height of the area exceeds 0.5m, the buoyancy plate 15 generates upward buoyancy due to seawater immersion, and the bearing base platform 11 can directionally perform upward floating movement, so that the influence of water level difference caused by wavelet surge fluctuation is effectively eliminated, and the dynamic floating bridge is ensured to be always kept in a correct butt joint state relative to the ocean-going large ship.

According to the verification of a plurality of experimental results, the floating amplitude of the bearing base platform 11 is controlled to be 15-30 mm, and the buoyancy plate 15 is preferably made of a material with low density, high structural strength and strong corrosion resistance.

As is also clear from fig. 3, a tension sensor 1314 is added to the pulling subunit 131 to sense in real time the variation of the pulling force applied by the mooring line 1312 to the pontoon module 1 due to the surge of the micro-amplitude waves. Tension sensor 1314 is mounted on anchor 1311 and is directly subject to tension from mooring line 1312. In practice, the pontoon module 1 is subjected to both surge forces and pulling forces from the mooring lines 1312. Under the circumstance of micro-amplitude surge (the height of the area wave is less than 0.5 m), the floating bridge module 1 will certainly surge (shake) due to the action of the impact force of the wave, meanwhile, the pulling force from the anchor rope 1312 sensed by the pulling force sensor 1314 also changes synchronously, and sends a control signal to the rotating motor 13131 in time, so that the rotating motor 13131 can be started or the working power changes, that is, the pulling force from the anchor rope 1312 sensed by the floating bridge module 1 changes to balance with the surge force caused by the micro-amplitude surge, and finally the floating bridge module 1 is ensured to be always kept in a balanced stress state, so that the surge floating amplitude is kept in a reasonable value range.

In addition, in order to further optimize the above technical solution, the flying bridge module 1 is further provided with a safety protection unit 16 as shown in fig. 1, 2 and 3, in view of the risk that the handler accidentally slips off the load-bearing base 11 due to a mistake or an impact from an external force. The safety guard unit 16 is mainly composed of a support base 161 and a toe guard 162. For a single set of pontoon module 1, 2 foot blocking plates 162 and 4 supporting seats 161 are simultaneously fitted. The 4-piece support bases 161 are fixed to the supporting base 11 and are held in an upright position. The 1-piece foot blocking plate 162 and the 2-piece supporting seat 161 cooperate to realize the enclosure of the front side of the bearing base platform 11; and the remaining 1-piece toe board 162 and 2-piece support base 161 cooperate to enclose the rear side of the load-bearing base 11.

In practical application, the floating seat 12 will shake slightly due to the wave impact force, and then will drive the bearing base 11 to fluctuate, and further will affect the standing stability of the loading and unloading workers to a certain extent. In view of the above, fig. 6 shows a schematic structural diagram of a pontoon module in a second embodiment of the dynamic pontoon for an island and a wharf according to the invention, which is different from the first embodiment in that: the floating bridge module 1 is also provided with a damping unit 17. The damping unit 17 connects the load-bearing base 11 and the floating base 12 at the same time. During the sea tide time, the bearing base 11 is always subjected to the damping force from the damping unit 17 during the process of performing the floating motion. The damping unit 17 is composed of 2 hydraulic dampers 171 connected between the floating base 12 and the supporting base 11 and symmetrically arranged in front and rear of the supporting base 11. In this way, in a scene with surge impact force, the bearing base 11 fluctuates due to the surge impact force, in the process, part of the kinetic energy is converted into the hydraulic potential energy of the hydraulic damper 171, and is released in a concentrated manner in the interval period of two surges, so that the adverse effect of the surge impact force on the bearing base 11 is effectively eliminated, and the smooth and safe passing of the loading and unloading workers and goods is ensured.
