Description

Technical Field

[0001] This invention relates to the field of dredging vessel equipment technology, and more specifically, to a trailing suction pipe hanger for a trailing suction dredger. Background Technology

[0002] A trailing suction hopper dredger is a highly efficient dredging vessel with self-propelled, self-loading, and self-unloading capabilities. Its core working component is the trailing suction pipe system, which dredges seabed sediment. The trailing suction pipe is typically deployed, suspended, and supported by a gantry system located at the stern. Traditional trailing suction pipe gantry systems are mostly basic support structures with relatively simple designs.

[0003] As dredging operations expand to the deep sea and efficiency requirements continue to increase, the trailing suction pipe system is becoming increasingly complex. In particular, the addition of high-efficiency underwater pumps poses a severe challenge to traditional gantry systems due to their significant weight and specific installation location. Existing gantry systems are usually only bolted to the hull, which can easily lead to instability or even swaying when the load on the gantry increases. Summary of the Invention

[0004] The purpose of this invention is to address the problem that the existing trailing suction pipe support of trailing suction dredgers is prone to instability or swaying when subjected to large tensile forces.

[0005] To achieve the above-mentioned objectives, the present invention provides the following technical solution:

[0006] A trailing suction hopper dredger's trailing suction pipe hanger includes a support base mounted on the hull, a mounting base mounted on top of the support base via reinforcing ribs, and a hanger body mounted on top of the mounting base. It also includes:

[0007] The mounting mechanism includes a locking component disposed on the top of the mounting base and a pressing component disposed on the side wall of the mounting base;

[0008] The reinforcing mechanism includes a supporting component disposed between the support base and the mounting base, and a stabilizing component disposed between the support base and the supporting component;

[0009] The adjustment mechanism includes a movable component disposed on the side wall of the support base and a positioning component disposed on the side wall of the support base and connected to the movable component.

[0010] As a preferred technical solution of this application, the locking component includes a fixed cylinder disposed on both sides of the top of the mounting base, a rotatable clamping plate disposed on both sides of the fixed cylinder, a first spring disposed between the two clamping plates located on the inner end face of the fixed cylinder, and a pulling component disposed inside the fixed cylinder.

[0011] As a preferred technical solution of this application, the pulling component includes a rotatable handle disposed at the bottom of the fixed cylinder, a winding wheel disposed at one end of the rotatable handle located inside the fixed cylinder, and a pulling rope disposed between the winding wheel and the clamping plate.

[0012] As a preferred technical solution of this application, the clamping component includes fixed plates disposed on both sides of the reinforcing rib plate, a rotating rod rotatably disposed between the two fixed plates and passing through the reinforcing rib plate, a pressure plate fixed to the outside of the rotating rod, a torsion spring sleeved on the wall of the rotating rod, and a rubber pad disposed on the inner top wall of the pressure plate.

[0013] As a preferred technical solution of this application, the support component includes a sliding plate slidably disposed on both sides of the support base, a support plate movably disposed between the sliding plate and the bottom of the mounting base, and a bolt threaded on the top edge of the sliding plate. The hull surface is provided with a positioning groove that mates with the bolt.

[0014] As a preferred technical solution of this application, the support plate includes a support frame movably disposed at the top of the slide plate and the bottom of the mounting base, a connecting plate slidably disposed between the two support frames, and a second spring disposed between the connecting plate and the inner wall of the support frame.

[0015] As a preferred technical solution of this application, the stabilizing component includes a biaxial cylinder disposed on the side wall of the reinforcing rib plate, piston rods disposed on both output ends of the biaxial cylinder, and a support frame disposed at the end of the piston rod and cooperating with the connecting plate.

[0016] As a preferred technical solution of this application, the moving component includes curved plates symmetrically arranged on both sides of the top edge of the support base, a screw threaded on the top of the curved plates, and a moving wheel rotatably arranged at the bottom of the screw. The top of the hull is provided with a rolling groove that cooperates with the moving wheel.

[0017] As a preferred technical solution of this application, the positioning component includes a sliding rod slidably mounted on the side wall of the reinforcing rib plate, a positioning plate disposed at the bottom of the sliding rod, a plurality of positioning blocks disposed at the bottom of the positioning plate, and a transmission component disposed between the positioning plate and the moving wheel. The top of the hull is provided with a pressure groove that cooperates with the positioning plate, and the bottom wall of the pressure groove is provided with a plurality of slots that cooperate with the positioning blocks.

[0018] As a preferred technical solution of this application, the transmission component includes a first toothed plate disposed on the side wall of the moving wheel, a gear rotatably disposed on the top of the support seat, and a second toothed plate disposed on the top of the positioning plate.

[0019] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0020] 1. First, install the support base on the hull, and then place the main body of the jack on top of the mounting base. At this time, the main body of the jack can be fixed on top of the mounting base by means of the locking component. No installation tools are required, making the operation simple and time-saving. Moreover, the clamping component can also squeeze the bottom plate of the jack body, further improving the stability of the jack body installation. This solves the problem of wasting time by fixing the jack body with bolts and installation tools in the existing technology.

[0021] 2. The supporting components can support the mounting base, preventing it from shaking due to excessive pressure. In addition, the stabilizing components can further support the supporting components, facilitating the distribution of pressure on the supporting components and further improving the stability of the main body of the hanger.

[0022] 3. When it is necessary to change the position of the support device, the support can be rolled on the top of the hull by the set moving part, which makes it easier to adjust the installation position of the main body of the hanger. After the position is adjusted, the moving part is retracted, and the positioning part can be driven by the transmission part to fix the support, improve the stability of the support and prevent the support from shaking or displacement.

[0034] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0035] like Figures 1 to 6 As shown, this embodiment proposes a trailing suction hopper gantry hanger, including a support base 3 mounted on the hull 1, a mounting base 4 mounted on the top of the support base 3 via reinforcing ribs 301, and a hanger body 2 mounted on the top of the mounting base 4. The hanger body 2 is characterized by further including an installation mechanism, a reinforcing mechanism, and an adjustment mechanism. The installation mechanism includes a locking component 5 mounted on the top of the mounting base 4 and a pressing component 6 mounted on the side wall of the mounting base 4. The reinforcing mechanism includes a supporting component 8 mounted between the support base 3 and the mounting base 4 and a stabilizing component 9 mounted between the support base 3 and the supporting component 8. The adjustment mechanism includes a moving component 10 mounted on the side wall of the support base 3 and a positioning component 11 mounted on the side wall of the support base 3 and connected to the moving component 10.

[0036] First, the support base 3 is installed on the deck of the hull 1. Then, the jack body 2 is placed on top of the mounting base 4. At this time, the locking component 5 can quickly fix the jack body 2 on the mounting base 4. At the same time, the pressing component 6 can squeeze the bottom edge of the jack body 2 to improve the stability of the jack body 2. When the jack body 2 is used to lift the rake suction pipe, the jack body 2 will bear a large tensile force. At this time, the support component 8 can support the mounting base 4 to prevent the mounting base 4 from shaking due to the large pressure of the jack body 2. Moreover, the stabilizing component 9 can also support the support component 8 to facilitate the distribution of the pressure on the support component 8, further improving the stability of the jack body 2. In addition, when it is necessary to adjust the position of the jack body 2, it is only necessary to first change the position of the support base 3 by moving component 10, and then fix the position of the support base 3 by positioning component 11, thereby avoiding the problem of the support base 3 shaking.

[0037] like Figure 2 and Figure 6 As shown, in a preferred embodiment, based on the above method, the locking component 5 further includes a fixed cylinder 501 disposed on both sides of the top of the mounting base 4, a clamping plate 502 rotatably disposed on both sides of the fixed cylinder 501, a first spring 503 disposed between the two clamping plates 502 located on the inner end face of the fixed cylinder 501, and a pulling component disposed inside the fixed cylinder 501.

[0038] The pulling component includes a rotatable handle 504 rotatably disposed at the bottom of the fixed cylinder 501, a winding wheel 505 disposed at one end of the rotatable handle 504 located inside the fixed cylinder 501, and a pull rope 506 disposed between the winding wheel 505 and the clamping plate 502.

[0039] When the base plate of the hanger body 2 is placed on the mounting base 4, the fixing cylinder 501 first passes through the mounting hole on the base plate of the hanger body 2. When the clamping plate 502 contacts the mounting hole, it is pressed into the fixing cylinder 501, compressing the first spring 503. When the base plate of the hanger body 2 is completely against the top of the mounting base 4, the fixing cylinder 501 also passes through the mounting hole on the base plate. At this time, the first spring 503 will eject the clamping plate 502 from the fixing cylinder 501, causing the clamping plate 502 to be locked in place on the hanger body 2. The upper surface of the base plate allows for quick and easy installation and fixation of the hanger body 2, saving time. When it is necessary to remove the hanger body 2 from the mounting base 4, simply turn the throttle 504 to drive the winding wheel 505 to rotate and wind up the pull rope 506. The pull rope 506 will then pull the clamping plate 502 back into the fixing cylinder 501. At this time, the clamping plate 502 will detach from the base plate of the hanger body 2, and the hanger body 2 will be released. Then, the hanger body 2 can be lifted off the mounting base 4 by a crane.

[0040] In addition, the clamping component 6 includes a fixing plate 601 disposed on both sides of the reinforcing rib plate 301, a rotating rod 602 rotatably disposed between the two fixing plates 601 and passing through the reinforcing rib plate 301, a pressure plate 603 fixed to the outside of the rotating rod 602, a torsion spring 604 sleeved on the rod wall of the rotating rod 602, and a rubber pad 605 disposed on the inner top wall of the pressure plate 603. Before installing the hanger body 2, the pressure plate 603 is first flipped away from the mounting base 4, so that the hanger body 2 can be placed on the mounting base 4 for fixing. Then the pressure plate 603 is released. Under the action of the torsion spring 604, the rotating rod 602 and the pressure plate 603 will reverse and reset, so that the pressure plate 603 is once again clamped at the top edge of the bottom plate of the hanger body 2. Moreover, under the action of the rubber pad 605, the pressure plate 603 will be clamped more tightly on the bottom plate, which can further improve the stability of fixing the hanger body 2.

[0041] like Figure 5 and Figure 6 As shown, in a preferred embodiment, based on the above method, the support component 8 further includes a sliding plate 801 slidably disposed on both sides of the support base 3, a support plate 802 movably disposed between the sliding plate 801 and the bottom of the mounting base 4, and a bolt 803 threadedly disposed at the top edge of the sliding plate 801. A positioning groove 104 that cooperates with the bolt 803 is provided on the surface of the hull 1.

[0042] The support plate 802 includes a support frame 8021 movably disposed at the top of the slide plate 801 and the bottom of the mounting base 4, a connecting plate 8022 slidably disposed between the two support frames 8021, and a second spring 8023 disposed between the connecting plate 8022 and the inner wall of the support frame 8021.

[0043] After the main body 2 of the hanger is installed on the mounting base 4, the slide plate 801 can be pulled out from the support base 3, and the support frame 8021 can slide out from the connecting plate 8022. Then, the slide plate 801 is fixed in the positioning groove 104 by bolts 803. At this time, the support plate 802 can support the mounting base 4 to prevent the mounting base 4 from shaking due to excessive weight of the main body 2 of the hanger and the rake suction pipe.

[0044] In addition, the stabilizing component 9 includes a dual-axis cylinder 901 disposed on the side wall of the reinforcing rib plate 301, piston rods 902 disposed on both output ends of the dual-axis cylinder 901, and a support frame 903 disposed at the end of the piston rod 902 and cooperating with the connecting plate 8022; the dual-axis cylinder 901 can also be activated to work, and the piston rod 902 drives the support frame 903 to move and abut against the bottom of the connecting plate 8022, thereby dispersing the pressure borne by the support plate 802 and further improving the stability of the support for the mounting base 4 and the hanger body 2.

[0045] like Figure 5 and Figure 6 As shown, in a preferred embodiment, based on the above method, the moving component 10 further includes curved plates 1001 symmetrically arranged on both sides of the top edge of the support base 3, a screw 1002 threaded on the top of the curved plate 1001, and a moving wheel 1003 rotatably arranged at the bottom of the screw 1002. A rolling groove 101 that cooperates with the moving wheel 1003 is opened on the top of the hull 1.

[0046] When it is necessary to adjust the installation position of the main body 2 of the hanger, the screw 1002 can be rotated first to drive the moving wheel 1003 to move downward and abut against the rolling groove 101 on the top of the hull 1. At this time, the support seat 3 can be pushed to move. Therefore, the position of the main body 2 of the hanger can be adjusted by changing the position of the support seat 3.

[0047] like Figure 5 and Figure 6 As shown, in a preferred embodiment, based on the above method, the positioning component 11 further includes a slide rod 1106 slidably mounted on the side wall of the reinforcing rib plate 301, a positioning plate 1104 disposed at the bottom of the slide rod 1106, a plurality of positioning blocks 1105 disposed at the bottom of the positioning plate 1104, and a transmission component disposed between the positioning plate 1104 and the moving wheel 1003. The top of the hull 1 is provided with a pressure groove 102 that cooperates with the positioning plate 1104, and the bottom wall of the pressure groove 102 is provided with a plurality of slots 103 that cooperate with the positioning blocks 1105.

[0048] The transmission components include a first toothed plate 1101 disposed on the side wall of the moving wheel 1003, a gear 1102 rotatably disposed on the top of the support base 3, and a second toothed plate 1103 disposed on the top of the positioning plate 1104.

[0049] After the position of the support base 3 is adjusted, the reverse screw 1002 drives the moving wheel 1003 to move upward and separate from the hull 1, so that the bottom of the support base 3 abuts against the surface of the hull 1. At this time, the moving wheel 1003 will drive the first toothed plate 1101 to move upward, the first toothed plate 1101 will drive the gear 1102 to rotate, and the gear 1102 will drive the positioning plate 1104 connected to the second toothed plate 1103 to move downward into the pressure groove 102. At this time, the positioning block 1105 at the bottom of the positioning plate 1104 will be locked into the slot 103 in the pressure groove 102, thereby limiting the support base 3 and further preventing the support base 3 from shaking or displacing, thus improving the stability of the main body 2 of the hanger.

[0050] The working principle of this invention is as follows: When the bottom plate of the hanger body 2 is placed on the mounting base 4, the first spring 503 will pop the clamping plate 502 out of the fixing cylinder 501, so that the clamping plate 502 is clamped on the upper surface of the bottom plate of the hanger body 2, and the hanger body 2 is quickly installed and fixed. The operation is simple and saves time. When it is necessary to remove the hanger body 2 from the mounting base 4, simply turn the handle 504 to drive the winding wheel 505 to rotate and wind up the pull rope 506. The pull rope 506 will then pull the clamping plate 502 back into the fixing cylinder 501. At this time, the clamping plate 502 is separated from the bottom plate of the hanger body 2, and the hanger body 2 will be released. Then, the hanger body 2 can be lifted off the mounting base 4 by a crane. After the main body 2 of the hanger is installed on the mounting base 4, the slide plate 801 can be pulled out from the support base 3, and the support frame 8021 can slide out from the connecting plate 8022. Then, the slide plate 801 is fixed in the positioning groove 104 by bolts 803. At this time, the support plate 802 can support the mounting base 4 to prevent the mounting base 4 from shaking due to excessive weight of the main body 2 of the hanger and the rake suction pipe. Furthermore, when it is necessary to adjust the installation position of the main body 2 of the hanger, the screw 1002 can be rotated first to drive the moving wheel 1003 to move downward and abut against the rolling groove 101 on the top of the hull 1. At this time, the support seat 3 can be pushed to move. Therefore, the position of the main body 2 of the hanger can be adjusted by changing the position of the support seat 3. After the position of the support seat 3 is adjusted, the screw 1002 is reversed to drive the moving wheel 1003 to move upward and separate from the hull 1, so that the bottom of the support seat 3 abuts against the surface of the hull 1. At this time, the moving wheel 1003 will drive the positioning plate 1104 to move downward into the pressure groove 102 through the first toothed plate 1101, the gear 1102 and the second toothed plate 1103. At this time, the positioning block 1105 at the bottom of the positioning plate 1104 will be inserted into the slot 103 in the pressure groove 102, thereby limiting the support seat 3, further preventing the support seat 3 from shaking and displacing, and improving the stability of the main body 2 of the hanger.

Although the present invention has been described in detail with reference to the above embodiments, the present invention is not limited to the specific embodiments described above.
