Description

Technical Field

[0001] The invention relates to the technical field of ship roll-on / roll-off equipment, and in particular to ship single-pipe pile ship roll-on / roll-off equipment. Background Art

[0002] Single-tube piles are a common type of pile required for offshore platform construction operations. They are large in size and highly corrosion-resistant. As large items for transportation, the transportation of single-tube piles requires the use of multiple roll-on / roll-off vehicles. Roll-on / roll-off vehicles have high loading and unloading efficiency and strong stability. The specific process is to lift the single-tube piles first and then load them, and then smoothly transfer them from the gangway to the large-item transport ship in a roll-on / roll-off manner, and finally unload the vehicle body.

[0003] Existing ship-borne roll-on / roll-off equipment has many technical defects when in use. First, the roll-on / roll-off vehicle is currently equipped with a hydraulic lifting device to lift and disassemble the roll-on / roll-off vehicle and the steel frame carrier. However, the hydraulic lifting device designed in the vehicle has a relatively complex structure and is difficult to install and disassemble. In addition, when the roll-on / roll-off vehicle drives the upper steel frame carrier to descend through hydraulic pressure, the impact force with the ground or deck is relatively large; second, the surface of the single-tube pile is coated with a protective paint layer, which is easy to collide with the steel frame carrier during the loading and falling process, resulting in damage to the paint layer, and the single-tube pile is also prone to strong shaking on the steel frame carrier during the process of entering the gangway, causing damage to the paint layer and safety problems; third, because the transport ship is affected by wind and waves at sea, the hull is easy to shake, causing the steel frame carrier to easily shift and slide on the deck, thereby reducing the stability of the single-tube pile placement and causing safety problems. In addition, the conventional solution is to use multiple sets of bolts to fix the bottom of the steel frame carrier, which is cumbersome to operate and it is not easy to open holes in the thick deck.

[0004] In summary, considering that the existing equipment cannot meet the work requirements, we propose a ship-mounted single-pipe pile loading and unloading equipment. Summary of the invention

[0023] The present invention provides a ship-mounted single-pipe pile ship-loading and rolling-on / roll-off equipment through improvement, which has the following significant improvements and advantages compared with the prior art:

[0024] The connector and automatic plug-in and pull-out device are designed so that the height of the movable steel frame carrier can be continuously lowered when the top rod is recovered. The plug column on the automatic plug-in and pull-out device is inserted into the through-port, and then the plug is used to prop open two sets of close single-pin pieces until the single-pin pieces extend into the corresponding plug slots and are locked to form a lock, so that each set of movable steel frame carriers is fixed on the roll-on / roll-off vehicle body, achieving the purpose of automatic connection and installation, and the installation is firm.

[0025] Design the connector and the automatic plug-in and pull-out device, start the servo motor, drive one of the groups of positioning shafts to rotate, and through several groups of sprockets and synchronous chain transmission, make each group of positioning shafts rotate synchronously in the same direction, the rotation angle is 90°, the positioning shaft drives the plug to rotate, make the two groups of slots rotate horizontally, separate from the single-pin piece respectively, release the limit lock, then when the push rod continues to descend, the upward reaction force lifts the movable steel frame carrier, so that the roll-on / roll-off vehicle body and the movable steel frame carrier in each group of roll-on / roll-off units are separated, and the plug column of each group of automatic plug-in and pull-out device is directly removed from the through-port upward with the movement of the movable steel frame carrier, which is convenient for the disassembly of the roll-on / roll-off vehicle body, the disassembly has a high degree of automation, and saves time and effort.

[0026] The single-tube pile is placed on the top seats of several groups of roll-on units. On the one hand, the single-tube pile compresses the bulging buffer airbag cushion through gravity, so that the buffer airbag cushion is pressed to be flush with the curved groove. The buffer airbag cushion has the function of buffering the downward pressure force, thereby protecting the paint layer of the single-tube pile. On the other hand, the gas inside the buffer airbag cushion is squeezed into the corresponding cylinder body pressure chamber, causing the cylinder telescopic rod to tilt and move upward, driving the spring steel sheet to contact the outer surface of the single-tube pile, squeezing the elastic clip, causing the elastic clip to deform and fit tightly to the outer surface of the single-tube pile. The multiple groups of spring steel sheets on both sides of the single-tube pile are symmetrically distributed, and therefore are subject to a uniform limiting effect, thereby reducing the degree of shaking of the single-tube pile during rotation, thereby achieving a protective effect.

[0027] The annular electromagnet is energized to generate electromagnetic suction on the steel deck, causing the annular electromagnet to move downward in the storage groove and adsorb to the deck, thereby limiting and fixing the load-bearing plate and the top rod, improving the stability of the steel frame carrier, avoiding displacement of the steel frame carrier, and compared with bolt connection, it saves time and effort and has high work efficiency.

DETAILED DESCRIPTION

[0042] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention. Example

[0043] like Figure 1-10 As shown, this embodiment provides a ship-borne single-pipe pile loading and unloading equipment, including a single-pipe pile 3 and a roll-on / roll-off unit, wherein a total of several groups of roll-on / roll-off units are evenly distributed at the lower end of the single-pipe pile 3, and the number of roll-on / roll-off units depends on the length of the single-pipe pile 3. The roll-on / roll-off unit includes a roll-on / roll-off vehicle body 1 and a movable steel frame carrier 10, and three groups of movable steel frame carriers 10 are evenly arranged at the upper end of each group of roll-on / roll-off vehicle bodies 1, and a driving wheel group 2 is arranged at the bottom of the roll-on / roll-off vehicle body 1, and the driving wheel group 2 includes an elastic shock absorbing system, and the elastic shock absorbing system reduces shock on the driving wheel.

[0044] Furthermore, a plurality of groups of connectors 7 are evenly distributed on the upper end surface of the roll-on / roll-off vehicle body 1 (corresponding to three groups of movable steel frame carriers 10, and a total of three rows of connectors 7 are arranged), such as Figure 3 shown.

[0045] Specifically, the connector 7 includes a connecting seat 71, an elastic bracket 72, a through hole 73, a single-leg piece 74, a U-shaped bracket 75, a limit rotation groove 76 and a gasket 77. Figure 4 shown.

[0046] In this embodiment, the connecting seat 71 is fixed on the upper end surface of the roll-on / roll-off vehicle body 1, and an elastic foot frame 72 is riveted to the lower end of the connecting seat 71. The middle part of the connecting seat 71 and the elastic foot frame 72 together form a through opening 73. A gasket 77 is installed at the upper end of the through opening 73. The gasket 77 plays a role in buffering and reducing contact friction. Two groups of single-leg pieces 74 are symmetrically arranged at the lower end of the elastic foot frame 72. The two groups of single-leg pieces 74 are close to each other and are made of spring steel, and have elastic deformation and reset capabilities.

[0047] In this embodiment, a U-shaped bracket 75 is downwardly connected to the outer side of the connecting seat 71 , the elastic bracket 72 is located inside the U-shaped bracket 75 , and a limited rotation groove 76 is provided at the middle position of the bottom of the U-shaped bracket 75 .

[0048] Furthermore, the movable steel frame carrier 10 includes a top seat 11 and a base 12 (both made of steel plates). Figure 5 and 6 shown.

[0049] The top seat 11 is located above the base 12, and the top seat 11 and the base 12 are connected by an angle iron frame to play a role of connecting support. The area between the top seat 11 and the base 12 forms a receiving cavity 13, such as Figure 5 and 6 shown.

[0050] Among them, the middle position of the base 12 is equidistantly installed with automatic plug-in and pull-out devices 8 adapted to several groups of connectors 7, and the upper end of the automatic plug-in and pull-out device 8 extends into the accommodating cavity 13, such as Figure 6 shown.

[0051] Specifically, the automatic plug-in / pull-out device 8 includes a positioning shaft 81, a damping bearing 82, a plug column 83, a plug 84, a slot 85, an arc portion 86 and a sprocket 87. Figure 7 and 8 shown.

[0052] In this embodiment, the positioning shaft 81 is rotatably arranged on the base 12 through a damping bearing 82. The damping bearing 82 has a certain rotation resistance. The lower end of the positioning shaft 81 is connected to a plug column 83. The plug column 83 is adapted to the through-hole 73 of the connector 7. The lower end of the plug column 83 is provided with a plug 84 that interacts with the elastic leg 72. The plug 84 plays the role of propping up the elastic leg 72. The side of the plug 84 is symmetrically provided with slots 85 for the single-leg piece 74 to extend into (the bottom of the slot 85 is provided with a blocking step), and the lower end of the plug 84 is provided with an arc portion 86 that extends into the limit rotation groove 76. The arc portion 86 has strong sliding properties, and the arc portion 86 and the limit rotation groove 76 rotate relative to each other, and the sizes of the two are adapted to each other.

[0053] Among them, the upper end of the positioning shaft 81 is sleeved with a sprocket 87 (two sets of sprockets 87 are sleeved on the positioning shaft 81 at the center position, and one set of sprockets 87 is sleeved on the positioning shaft 81 at the side position), and the sprockets 87 between adjacent automatic plug-ins 8 are sequentially connected through a synchronous chain 30. A coupling 31 is provided at the upper end of one set of positioning shafts 81, and a servo motor 32 is installed at the upper end of the coupling 31. The top of the servo motor 32 is fixed to the lower end surface of the top seat 11, which plays a role of connection and fixing. Figure 6-7 shown.

[0054] Furthermore, two groups of hydraulic jacks 15 are symmetrically arranged on the side of the lower end surface of the base 12 and on the outside of the roll-on / roll-off vehicle body 1 (located on the outside of the roll-on / roll-off vehicle body 1 for easy installation and removal, as well as maintenance). The upper end of each group of hydraulic jacks 15 is riveted to the lower end of the base 12 through a fixing seat 14. An electric oil supply 16 is also installed on the base 12 to automatically supply oil to the hydraulic jacks 15. Figure 5 and 6 shown.

[0055] Among them, the hydraulic jack 15 is provided with a push rod 17 inside which moves downward. When several groups of push rods 17 extend downward, they act on the deck of the transport ship, and the upward reaction force lifts up the movable steel frame carrier 10, so that the roll-on / roll-off vehicle body 1 and the movable steel frame carrier 10 are separated. Figure 6 shown.

[0056] Furthermore, a curved groove 20 is provided at the middle position of the upper end surface of the top seat 11, and a buffer airbag cushion 21 is provided in the curved groove 20. The buffer airbag cushion 21 bulges under normal conditions and partially extends out of the curved groove 20. The buffer airbag cushion 21 has deformation restoration capability. The buffer airbag cushion 21 is in contact with the single-tube pile 3. The bottom of the buffer airbag cushion 21 is fixed in the curved groove 20 through a connecting base 22, which plays a connecting limit role. Figure 5 and 9 shown.

[0057] Furthermore, the two end surfaces of the buffer airbag cushion 21 are symmetrically connected with a plurality of groups of air guide tubes 92, and each group of air guide tubes 92 is externally connected with a pneumatic support structure 9, such as Fig. 9 shown.

[0058] Specifically, the pneumatic support structure 9 includes a cylinder body 91, an air guide pipe 92 and a cylinder telescopic rod 93. Fig.10 shown.

[0059] In this embodiment, the cylinder body 91 is tilted and fixed at the inner edge position of the top seat 11, the internal pressure chamber of the cylinder body 91 is connected to the air guide pipe 92, and a cylinder telescopic rod 93 is extended upward from the inside of the cylinder body 91, and the cylinder telescopic rod 93 tilts out of the upper end surface of the top seat 11.

[0060] Specifically, the pneumatic support structure 9 also includes a support block 94, a spring steel sheet 95, an elastic clip 96 and a wear-resistant buffer pad 97. Fig.10 shown.

[0061] In this embodiment, a support block 94 is welded to the upper end of the cylinder telescopic rod 93, and a spring steel sheet 95 is welded to the upper end of the support block 94. An elastic clip 96 acting on the outer surface of the single-tube pile 3 is provided on the spring steel sheet 95 (the elastic clip 96 undergoes a certain degree of deformation under the action of pressure, and causes the root of the spring steel sheet 95 to bend). The elastic clip 96 has the ability to restore the deformation, and a layer of wear-resistant buffer pad 97 is provided on the surface of the elastic clip 96, which protects the paint layer of the single-tube pile 3.

[0062] Furthermore, the hydraulic jacks 15 on all the roll-on / roll-off units are electrically connected and work synchronously.

[0063] When the present embodiment is in use, at the ground stage, two groups of top rods 17 are first used to descend and contact the ground to provide planar support for the movable steel frame carrier 10. Three groups of movable steel frame carriers 10 are equidistantly arranged according to this method, and then the roll-on / roll-off vehicle body 1 is driven to enter under the movable steel frame carrier 10. The automatic plug-in / pull-out device 8 on each group of movable steel frame carriers 10 corresponds to the connector 7 on the roll-on / roll-off vehicle body 1 up and down. Then, the top rods 17 are slowly retracted to continuously lower the height of the movable steel frame carrier 10. The plug column 83 on the automatic plug-in / pull-out device 8 is inserted into the through-port 73, and then the plug 84 is used to prop open the two groups of adjacent single-leg pieces 74 until the single-leg piece 74 extends into the slot 85 of the corresponding plug 84 and is locked to form a lock, so that each group of movable steel frame carriers 10 is fixed on the roll-on / roll-off vehicle body 1 to form a roll-on / roll-off unit, and part of the supporting force is transferred to the roll-on / roll-off vehicle body 1.

[0064] At this time, the single-tube pile 3 is lifted by a crane, and then slowly placed down on the curved groove 20 of the top seat 11 of several groups of roll-on units. The single-tube pile 3 compresses the bulging buffer airbag cushion 21 by gravity, so that the buffer airbag cushion 21 is pressed to be flush with the curved groove 20, and the gas inside the buffer airbag cushion 21 is discharged outward through several groups of air guide pipes 92 and enters the corresponding pressure chamber of the cylinder body 91, causing the cylinder telescopic rod 93 to tilt and move upward, driving the spring steel sheet 95 to approach the outer surface of the single-tube pile 3. The two are in contact, squeezing the elastic clip 96, causing the elastic clip 96 to deform and fit tightly to the outer surface of the single-tube pile 3. The multiple groups of spring steel sheets 95 on both sides of the single-tube pile 3 are symmetrically distributed, and therefore are subject to uniform limiting effects.

[0065] The push rod 17 continues to be recovered in place, and then the remote control driving wheel group 2 moves, and several groups of roll-on and roll-off units jointly drive the single pipe pile 3 to move, and enter the deck of the transport ship through the connecting springboard in turn. At this time, several groups of hydraulic jacks 15 work synchronously, and the push rod 17 slowly descends until it touches the deck to form a support, and then the servo motor 32 is started to drive the positioning shaft 81 of one group of automatic plug-in and pull-out devices 8 to rotate, and through several groups of sprockets 87 and synchronous chains 30, the positioning shaft 81 of each group of automatic plug-in and pull-out devices 8 rotates synchronously in the same direction, and the rotation angle is 90°. The positioning shaft 81 drives the plug 84 to rotate, so that the two groups of card slots 85 are water-locked. The jack 17 then rotates horizontally and separates from the single-leg piece 74, releasing the limit lock, thereby releasing the restraint of the automatic plug-in and pull-out device 8. At this time, when the push rod 17 continues to descend, the upward reaction force generated lifts up the movable steel frame carrier 10, so that the roll-on and roll-off vehicle body 1 and the movable steel frame carrier 10 in each roll-on and roll-off unit are separated (the plug column 83 of each set of automatic plug-in and pull-out device 8 directly escapes from the through-hole 73 as the movable steel frame carrier 10 moves upward). The roll-on and roll-off vehicle body 1 is no longer used as a supporting unit and can be directly withdrawn, so that the single-tube pile 3 is supported and positioned on the deck of the transport ship through several sets of movable steel frame carriers 10, and is transported at sea with the transport ship. Example

[0066] On the basis of the first embodiment, since the transport ship is affected by wind and waves at sea, the hull is easy to shake, causing the top rod 17 that contacts and supports the deck to easily slide on the deck, thereby reducing the stability of the single-tube pile 3 and causing safety problems. In addition, the top rod 17 is fixed with multiple sets of bolts, which is cumbersome to operate, and it is not easy to open a hole in the thick deck. In order to solve the above technical problems, we have the following design solutions, such as Figure 11-13 shown.

[0067] Specifically, a load-bearing plate 40 is provided at the lower end of the top rod 17. The load-bearing plate 40 is made of manganese steel alloy and has excellent compressive load-bearing performance. The top rod 17 contacts the deck plane of the transport ship using the load-bearing plate 40. An annular protective sleeve 41 is sleeved on the outer side of the load-bearing plate 40. A storage groove 42 is provided inside the annular protective sleeve 41. Fig.11 and 12 shown.

[0068] Furthermore, an annular electromagnet 43 acting on the deck of the transport ship is installed in the storage groove 42, and a plurality of groups of tension springs 44 are evenly arranged on the upper end surface of the annular electromagnet 43, and the upper end of the tension spring 44 is connected and fixed to the top of the annular protective cover 41 (under normal conditions, the annular electromagnet 43 is subjected to the traction force of the tension spring 44, and the lower end surface height is lower than the lower end surface height of the annular protective cover 41 to avoid direct contact with the ground or the deck). Fig.12 and 13 shown.

[0069] The annular electromagnet 43 is connected to a power source via a wire 45. Fig.13 shown.

[0070] When this embodiment is in use, the top rod 17 uses the load-bearing plate 40 to contact the deck to support the entire upper structure, and then the annular energized electromagnet 43 is energized to generate electromagnetic suction acting on the steel deck, causing the annular energized electromagnet 43 to move downward in the storage groove 42 (several groups of tension springs 44 are elastically stretched) and adsorbed with the deck, thereby limiting and fixing the load-bearing plate 40 and the top rod 17. When the annular energized electromagnet 43 is de-energized, the restoring force generated by the pulling of the tension spring 44 drives the annular energized electromagnet 43 to return to its position upward.
