Description

Technical Field

[0001] This utility model relates to the technical field of mooring and throwing devices for water transport engineering vessels, and in particular to a device for throwing bagged sand from a ballast-throwing vessel. Background Technology

[0002] The riverbed of the middle and lower reaches of the Yangtze River in my country is composed of easily eroded fine sand with a thick layer, which leads to drastic changes in the riverbed and causes significant undulations in the underwater topography, affecting navigation. To reinforce the stability of the riverbed, users often need to fill sandbags with mortar into the riverbed, thus requiring the use of sandbag throwing vessels. The sandbag throwing operation involves moving and positioning the vessel, then mooring the sand barge alongside the sandbag throwing vessel for filling the sandbags and throwing the sandbags. Currently, many sandbag throwing vessels in the Yangtze River waterway are simple double-sided sandbag throwing vessels converted from deck barges. Their working area is narrow, and after the sand transport system is set up, there are two flushing pumps driving four water guns, and two sand suction pumps sharing the limited deck space with the sandbag throwing vessels. Each sandbag throwing cycle involves the dismantling and deployment of pipelines, a process that takes 20 minutes to complete.

[0003] Meanwhile, the throwing of pillows on the throwing boats is mostly done manually by using a hook locking device to restrict the rotation of the pillow frame. Because it is manual operation, the throwing of pillows and the reset of the pillow frame, especially the reset, often require 1-3 people to control one pillow frame. A long steel pipe is inserted into the reset hole to forcibly rotate the vertical pillow frame around the eccentric axis to reset it, so that the inner edge of the pillow frame is restricted within the hook. This process has safety risks, consumes too much manpower and time, and usually takes 8-10 minutes. Therefore, the time of each process in a single cycle of pillow throwing is mutually restrictive, resulting in low throwing efficiency. Furthermore, because it is mostly manual operation, the weight of the pillow bed must be lightweight. As a result, these modified pillow beds have a relatively simple structure and low strength. However, because the sand pillow bags are heavy, the surface of the pillow bed is prone to bending and deformation over time. When the pillow bed is upright, the slippage of the pillow bag is uncontrollable, affecting the accuracy of the throwing and reducing its practicality.

[0004] In summary, existing modified simple pillow-throwing boats are limited by the original conditions of the vessel and the cost of modification. Furthermore, since they are mostly operated manually, the pillow bed structure must be lightweight and simplified. Over time, the surface of the pillow bed will deform, which is not conducive to filling sand pillow bags and throwing pillows. Moreover, the operation equipment is basically controlled manually, relying on the experience of the crew to throw pillows manually, which is unsafe, time-consuming, inefficient, and has low construction benefits and practicality. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this utility model provides a device for throwing bagged sand on a sand-throwing vessel. It addresses the limitations of existing modified, simple sand-throwing vessels, which are constrained by the vessel's original conditions and modification costs. Furthermore, because they are mostly manually operated, the sand-throwing bed structure must be lightweight and simplified, leading to surface deformation over time, which hinders sand filling and throwing. Additionally, the operation is primarily manual, relying on crew experience for manual throwing, resulting in poor safety, long turnaround times, low throwing efficiency, low construction benefits, and limited practicality.

[0006] According to an embodiment of this utility model, a device for throwing bagged sand on a ballast ship is provided. The device is installed on the deck of a ship and includes a rectangular ballast bed. The ballast bed includes a load-bearing plate and a support frame fixed to the bottom surface of the load-bearing plate. The ballast bed is located in the edge area of ​​the deck, with one side of the ballast bed hinged to the edge of the deck. It also includes two jacking components, which are arranged side by side on the bottom of the ballast bed opposite the edge of the deck. The top and bottom of the jacking components are rotatably connected to the bottom of the ballast bed and the deck, respectively. The jacking components drive the ballast bed to rotate around the edge of the deck. The rotation direction of the top and bottom of the jacking components is the same as the rotation direction of the ballast bed around the edge of the deck.

[0007] Furthermore, the support frame includes main longitudinal beams and main transverse beams that intersect in a cross structure, and several auxiliary longitudinal beams arranged side by side on both sides of the main transverse beams. The auxiliary longitudinal beams are fixedly connected to the main transverse beams at their middle positions. The frame also includes side longitudinal beams and side transverse beams fixedly connected to the adjacent two edges of the bottom of the load-bearing plate. The intersection of the main transverse beams and the main longitudinal beams coincides with the center point of the load-bearing plate. The two ends of the main longitudinal beams away from the intersection point extend to the side transverse beams and are vertically fixedly connected to the middle positions of the side transverse beams. The two ends of the main transverse beams extend to the side longitudinal beams and are vertically fixedly connected to the middle positions of the side longitudinal beams.

[0008] Furthermore, the load-bearing plate is provided with several through holes on one side near the edge of the ship's deck. The through holes are arranged in a straight line and parallel to the edge of the ship's deck. Several columns are also vertically fixed on the side beam on the other side of the load-bearing plate away from the through holes. The side walls of the columns are fixedly connected to the side walls of the side beams and the tops protrude from the load-bearing plate.

[0009] Furthermore, the upper surface of the load-bearing plate is also provided with several fixing ropes, one end of which is tied to the upper part of the column and the other end passes through the upper surface of the load-bearing plate and through the corresponding through hole.

[0010] Furthermore, the upper surface of the hull deck is also provided with a support seat and a bearing mounted on the support seat. The side beam near the edge of the hull deck is provided with a corresponding support seat and a rotating shaft. The load-bearing plate is rotatably connected to the hull deck by means of the rotating shaft, the bearing, and the support seat.

[0011] Furthermore, the jacking assembly includes a hydraulic push rod, and a groove is provided on the hull deck covered by the load-bearing plate. The bottom of the hydraulic push rod is rotatably connected to the bottom of the groove, and the top drive end is rotatably connected to the bottom of the auxiliary longitudinal beam near the edge of the load-bearing plate. When the load-bearing plate is driven, the bottom and top of the hydraulic push rod rotate synchronously.

[0012] Furthermore, the pillow bed has two pieces arranged side by side on one side of the main deck.

[0013] Furthermore, three buffer seats are vertically fixed in a straight line and parallel to the edge of the hull deck area covered by the load-bearing plate.

[0014] The technical principle of this utility model is as follows: by hinged to the main deck side, the jacking component drives the rotation of the pillow bed, realizing the automatic control effect of pillow throwing and resetting. This overcomes the drawbacks of manual control of pillow throwing and resetting on existing pillow throwing ships, reduces labor consumption, and reduces the unsafe factors of pillow throwing and resetting. At the same time, since the manual pillow throwing is replaced by automatic pillow throwing, there is no need to consider the weight reduction of the pillow bed due to manual reasons. Therefore, the structure of the pillow bed is strengthened. A frame is set at the bottom of the load-bearing plate to strengthen the overall structural strength of the pillow bed, avoiding the problem of the load-bearing plate being deformed by the heavy pillow bag, and ensuring that the upper surface of the load-bearing plate remains flat and free from deformation.

[0021] The technical solution of this utility model will be further described below with reference to the accompanying drawings and embodiments.

[0022] like Figure 1 and Figure 2 As shown in the figure, this utility model embodiment proposes a device for throwing bagged sand on a ballast ship. The device is installed on the deck 1 of the ship and includes a rectangular ballast bed 2. The ballast bed 2 is located in the edge area of ​​the deck 1, and one side of the ballast bed 2 is hinged to the edge of the deck 1. It also includes two jacking components 3, which are arranged side by side on the bottom of the ballast bed 2 opposite to the edge of the deck 1. The top and bottom of the jacking components 3 are rotatably connected to the bottom of the ballast bed 2 and the deck 1, respectively. The jacking components 3 drive the ballast bed 2 to rotate around the edge of the deck 1. The rotation direction of the top and bottom of the jacking components 3 is the same as the rotation direction of the ballast bed 2 around the edge of the deck 1.

[0023] like Figure 1 and Figure 2 As shown, the pillow bed 2 includes a load-bearing plate 22 and a support frame 21 fixed to the bottom surface of the load-bearing plate 22. The support frame 21 includes a main longitudinal beam 211 and a main transverse beam 212 that cross each other in a cross structure, and several auxiliary longitudinal beams 213 arranged side by side on both sides of the main transverse beam 212. The middle position of the auxiliary longitudinal beams 213 is fixedly connected to the main transverse beam 212. It also includes side longitudinal beams 214 and side transverse beams 215 that are fixedly connected to the adjacent two sides of the bottom of the load-bearing plate 22. The intersection point of the main transverse beam 212 and the main longitudinal beam 211 coincides with the center point of the load-bearing plate 22. The two ends of the main longitudinal beam 211 away from the intersection point extend to the side transverse beam 215 and are vertically fixedly connected to the middle position of the side transverse beam 215. The two ends of the main transverse beam 212 extend to the side longitudinal beam 214 and are vertically fixedly connected to the middle position of the side longitudinal beam 214.

[0024] like Figure 1 and Figure 2 As shown, by hinged to the main deck side, the jacking assembly 3 drives the rotation of the pillow bed 2, achieving automatic control of pillow throwing and resetting. This overcomes the drawbacks of manual control of pillow throwing and resetting in existing pillow throwing ships, reducing labor costs and safety risks associated with pillow throwing and resetting. Furthermore, since manual pillow throwing is replaced with automatic throwing, there is no need to consider lightweighting the pillow bed 2 due to manual labor. Therefore, the structure of the pillow bed 2 is strengthened. A frame is installed at the bottom of the load-bearing plate 22 to enhance the overall structural strength of the pillow bed 2, preventing the load-bearing plate 22 from deforming under the weight of the pillow bag and ensuring that the upper surface of the load-bearing plate 22 remains flat and free from deformation.

[0025] like Figure 1 and Figure 2As shown, in the support frame 21, the main crossbeam 212 and the main longitudinal beam 211 are 20-type channel steel, the side crossbeam 215 is 26-type I-beam, the side beam is 22-type I-beam, and the longitudinal auxiliary beam is 12-type channel steel. The steel beams are connected by welding. The support frame 21 is used to support the load-bearing plate 22. When bagged sand pillows and workers gather on the load-bearing plate 22, the load-bearing plate 22 does not deform.

[0026] like Figure 1 and Figure 2 As shown, furthermore, the load-bearing plate 22 has several through holes 221 on one side near the edge of the hull deck 1. These through holes 221 are arranged in a straight line and parallel to the edge of the hull deck 1. On the other side of the load-bearing plate 22, away from the through holes 221, several columns 223 are vertically fixed on the side beam 215. The sidewalls of the columns 223 are fixedly connected to the sidewalls of the side beam 215, and their tops protrude from the load-bearing plate 22. Several fixing ropes 222 are also provided on the upper surface of the load-bearing plate 22. One end of each fixing rope 222 is tied to the top of the column 223, and the other end passes through the load-bearing plate 222. The upper surface of the pillow bed 2 and the corresponding through hole 221 are passed through it. The column 223 is made of steel pipe and welded to the side beam 215 for the fixing rope 222 to tie. When filling the sand pillow bag, the empty bag is placed on the upper surface of the pillow bed 2. One end of the fixing rope 222 is fixed in advance to the knot fixing point on the hull deck 1, and the other end extends from the bottom of the pillow bed 2 through the through hole 221, and is pulled from the top of the sand pillow bag and then looped on the column 223. When sand is transported into the sand pillow bag, the fixing rope can hold the sand pillow bag and stabilize it before throwing, preventing the sand pillow bag from slipping into the water in case of accidents.

[0027] like Figure 1 and Figure 2 As shown, the upper surface of the hull deck 1 is further provided with a support seat 24 and a bearing 23 provided on the support seat 24. The side beam 215 near the edge of the hull deck 1 is provided with a corresponding support seat 24 and a rotating shaft. The load-bearing plate 22 is rotatably connected to the hull deck 1 by means of the rotating shaft, the bearing 23 and the support seat 24.

[0028] like Figure 1 and Figure 2As shown, the jacking assembly 3 further includes a hydraulic push rod 31. A groove 32 is also provided on the hull deck 1 covered by the load-bearing plate 22. Since the throwing vessel has a multi-layered hull structure, such as a second deck or bottom plate, the groove 32 extends through the hull deck 1. The bottom of the hydraulic push rod 31 is located within the groove 32 and rotatably connected to the hull structure of the groove 32. The top driving end extends out of the groove 32 and rotatably connects to the bottom of the auxiliary longitudinal beam 213 near the edge of the load-bearing plate 22. When the load-bearing plate 22 is driven, the bottom and top of the hydraulic push rod 31 rotate synchronously to prevent interference. By starting and stopping the hydraulic push rod 31, the pillow bed 2 rotates around the bearing 23 and support seat 24, completing the operations of filling the pillow with bagged sand, throwing the pillow, and resetting the pillow bed 2.

[0029] Furthermore, such as Figure 1 Figure 2 As shown, the pillow bed 2 consists of two pieces arranged side by side on one side of the hull deck 1. Each pillow bed 2 is 8.1 meters long and 6 meters wide. Since existing sand-dropping vessels are mostly simple double-sided pillow-dropping vessels converted from deck barges, the working area between the two sides of the ship is relatively narrow, while there is ample space between the bow and stern. Therefore, changing it to single-sided throwing avoids the problem of a narrow working area between the two sides. Simultaneously, arranging the pillow beds side by side utilizes the distance between the bow and stern, making reasonable use of the space on the hull deck. This ensures full utilization of the working area of ​​the sand-dropping vessel. Furthermore, the increased working area allows for the simultaneous filling and dropping of more sand pillow bags, thereby increasing throwing efficiency.

[0030] like Figure 1 and Figure 2 As shown, furthermore, three buffer seats 11 arranged in a straight line and parallel to the edge of the hull deck 1 are vertically fixed in the area covered by the load-bearing plate 22. The height of the buffer seats 11 corresponds to the height of the pillow bed 2 and the support seats 24 at the edge of the hull deck 1. The buffer seats 11 are welded to the hull deck 1 by steel pipes. At the same time, when the pillow bed 2 is in the flat and reset state, buffer seats 11 of different heights can be selected according to the distance between each steel beam on the support frame 21 and the hull deck 1. For example, the buffer seats 11 located at the position of the main longitudinal beam 211 and the buffer seats 11 located at the positions of the auxiliary longitudinal beams 213 on both sides of the main longitudinal beam 211. Since the dimensions of these two types of steel beams are different, buffer seats 11 of different heights must be selected to adapt to the height. When the pillow bed 2 is reset, during the process of filling the pillow bed 2 with bagged sand, the three buffer seats 11 in a straight line and the two support seats 24 jointly support the pillow bed 2 and maintain the stability of the pillow bed 2.

[0031] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
