Description

Technical Field

[0001] The present invention belongs to the technical field of ship engineering, and particularly relates to an improved structure and method for a launching barge. Background Art

[0002] The hull of the launching barge consists of a large floating box main body and four towers respectively located at the four corners above the floating box main body (as Figure 1 shown), and devices such as a main ballast water pump, a mooring shore power connection box, and a measurement control operation device are also provided on the launching barge. The hull is of all-welded structure and can adopt two ways of longitudinal berthing or transverse berthing for the ship launching operation. When operating, the equipment on the ship takes the electricity provided by the shore motor as the main power source.

[0003] Among them, the floating box main body is a watertight box structure, which provides the main buoyancy and longitudinal strength for the launching barge. The four towers at the four ends provide the overall stability to ensure that when the ship enters and exits the launching barge, the mechanical parameters and strength such as the section modulus of the floating box main body structure meet the requirements. When the launching barge sinks and floats, the floating box main body can provide sufficient buoyancy, and the buoyancy is about the length * width * height (tons) of the floating box main body, which guarantees the safety of the launching barge's sinking and floating operation. When the launching barge dives, the floating box main body is submerged underwater. At this time, the overall stability of the launching barge is provided by the towers, which can ensure the stability safety during the diving operation of the launching barge.

[0004] When the width of the ship is less than the inner width between the front towers, it meets the width requirement for the ship to enter and exit longitudinally, and is applicable to the construction operation of non-overwidth ships entering and exiting the launching barge. When the width of the ship is greater than the inner width between the front towers but the length is less than the inner length between the head and tail towers of the launching barge, it can meet the overwidth requirement for the ship to enter and exit transversely, and is applicable to the construction operation of overwidth ships entering and exiting the launching barge transversely.

[0005] In shipbuilding and ship repair projects in shipyards, the generally designed launching barges are only used for the launching function of ships after construction on the land shipbuilding berth. Their functional uses are relatively single, and the underutilized ones will form idle asset equipment, resulting in waste of resources. Summary of the Invention

[0006] The purpose of the present invention is to provide an improved structure and method for a launching barge, so as to solve the problems of the existing launching barge having single functional uses, low utilization rate, and being prone to idleness resulting in waste of resources.

[0007] To achieve the above purpose, an improved structure for a launching barge provided by an embodiment of the present invention includes a launching barge body. The launching barge body includes a floating box main body and four towers respectively arranged at the four ends of the floating box main body, and further includes a temporary floating box. The temporary floating box is respectively installed on both sides above the floating box main body and is located in the middle of the head and tail towers; the temporary floating box is a watertight steel structure box.

[0008] Furthermore, the temporary floating caisson is a detachable structure.

[0009] Furthermore, the number of temporary floating caissons located in the middle of both sides of the floating caisson body can be multiple, and the number and combination form of the temporary floating caissons on both sides of the floating caisson body are the same.

[0010] Furthermore, multiple temporary floating caissons can be vertically stacked and installed to form a multi-layer temporary floating caisson structure.

[0011] Furthermore, multiple temporary floating caissons are horizontally arranged between the head and tail towers to form an independent non-continuous temporary floating caisson structure.

[0012] Furthermore, an upper-level passage is also provided. The upper-level passage is arranged above the temporary floating caisson and is connected to the head and tail towers on both sides of the temporary floating caisson at both ends.

[0013] Furthermore, a docking pier is detachably installed in the middle of the top surface of the floating caisson body, and the docking pier is symmetrically arranged from the middle to both sides.

[0014] An improvement method for a launching barge, including the above-mentioned improved structure of the launching barge, comprises the following steps:

[0015] S1. The launching barge docks at the shore, and the temporary floating caisson is installed in the middle of both sides of the floating caisson body to form a floating dock ship type that can be used for the launching and repair of small ships.

[0016] S2. The launching barge is flooded and submerged, the ship to be repaired is transported into the launching barge, the launching barge drains water and floats up out of the water surface, and the ship can be stabilized on the launching barge for repair work.

[0017] S3. After the ship repair is completed, the launching barge is reflooded and submerged, and the ship sails out of the launching barge by itself.

[0018] Furthermore, in step S1, the temporary floating caisson is a detachable structure.

[0019] Furthermore, in step S1, an upper-level passage is arranged between the head and tail towers and above the temporary floating caisson for connecting the head and tail towers.

[0020] One or more of the above technical solutions in the improved structure and method of the launching barge provided by the embodiments of the present invention have at least the following technical effects:

[0021] Temporary floating boxes are provided on both sides above the floating box body of the launching barge, which does not affect the launching function of the ship entering and leaving the launching barge. Moreover, the temporary floating boxes are similar in structure to the floating box body and are watertight steel structure boxes. Their structural form is simple and convenient for construction, but they can assist in increasing the overall displacement and overall buoyancy of the launching barge, improving the overall stability of the launching barge. The increased buoyancy value is the length * width * height (tons) of the temporary floating box, and it is ensured that the diving depth of the launching barge is less than the maximum sinking depth (the sum of the heights of the floating box body and the temporary floating box), providing a better stable environment for the actual floating and sinking operations of the launching barge, improving the use safety, and can be applied to the maintenance business of ships.

[0022] Since the floating box body provides buoyancy and the four towers at the four ends provide overall stability, meeting the requirements of the classification code for the design and construction of basic floating docks, the added temporary floating boxes make the launching barge into a non-self-propelled floating dock ship type, enabling the improved launching barge to have both the functions of ship launching and repair at the same time, improving the utilization rate of the launching barge, avoiding the idle waste of assets, and meeting the full-load production needs of the shipyard.

For those of ordinary skill in the art, the specific meanings of the above terms in the embodiments of the present invention can be understood according to specific circumstances.

[0035] In an embodiment of the improved structure of the launching barge of the present invention, please refer to Figures 2 to 5 . The improved structure of the launching barge includes a launching barge body 100. The launching barge body 100 includes a floating box main body 110 and four towers 120 respectively arranged at the four ends of the floating box main body 110. It further includes a temporary floating box 200. The temporary floating boxes 200 are respectively installed on both sides above the floating box main body 100 and are located in the middle of the head and tail towers 120; the temporary floating box 200 is a watertight steel structure box.

[0036] Specifically, temporary floating boxes 200 are provided on both sides above the floating box main body 110 of the launching barge, which does not affect the launching function of the ship entering and leaving the launching barge 100. Moreover, the temporary floating box 200 is similar in structure to the floating box main body 110 and is a watertight steel structure box. Its structural form is simple and convenient for construction, but it can assist in increasing the overall displacement and overall buoyancy of the launching barge 100, improving the overall stability of the launching barge 100. The increased buoyancy value is the length * width * height (tons) of the temporary floating box 200, and it is ensured that the diving depth of the launching barge 100 is less than the maximum sinking depth (the sum of the heights of the floating box main body 110 and the temporary floating box 200), providing a better stable environment for the actual floating and sinking operation of the launching barge 100, improving the use safety, and can be applied to ship repair operations.

[0037] Since the floating box main body 110 provides buoyancy and the four towers 120 at the four ends provide overall stability, meeting the requirements of the classification code for the design and construction of basic floating docks, the added temporary floating box 200 enables the launching barge 100 to become a non-self-propelled floating dock ship type, improving the utilization rate of the launching barge 100, enabling the improved launching barge 100 to have both ship launching and repair functions at the same time, avoiding the idle waste of assets, and meeting the full-load production needs of the shipyard.

[0038] Furthermore, the temporary floating box 200 is a detachable structure. Specifically, when the width of the ultra-wide ship is greater than the inner width of the front tower 120 of the launching barge and the length is less than the net length between the front and rear towers 120, the temporary floating box 200 blocks the entry and exit of the ultra-wide ship. The temporary floating box 200 can be temporarily disassembled and lifted off, allowing the ultra-wide ship to enter and exit the launching barge 100 laterally, and then reinstalling the temporary floating box 200. The detachable temporary floating box 200 can be repeatedly installed and disassembled according to actual production needs, facilitating construction, meeting the high-efficiency construction needs at a low cost, and improving efficiency.

[0039] Furthermore, the number of temporary floating boxes 200 located in the middle of both sides of the floating box main body 110 can be multiple, and the number and combination form of the temporary floating boxes 200 on both sides of the floating box main body 110 are the same. Specifically, multiple temporary floating boxes 200 can assist in increasing more buoyancy values of the launching barge 100. The number and combination form of the temporary floating boxes 200 on both sides are the same, ensuring the overall stability of the launching barge 100, thereby improving the safety construction coefficient and improving the safety construction operation. Preferably, multiple temporary floating boxes 200 can be vertically stacked and installed to form a multi-layer temporary floating box structure. Or multiple temporary floating boxes 200 are horizontally arranged between the front and rear towers 120 to form an independent non-continuous temporary floating box structure. Among them, the number of temporary floating boxes 200 on one side is preferably 2, and the two combination forms can be installed and disassembled according to actual production needs.

[0040] Further, an upper channel 300 is also provided. The upper channel 300 is arranged above the temporary floating box 200 and is connected to the head and tail towers 120 on both sides of the temporary floating box 200 at both ends. Specifically, the upper channel 300 communicates with the head and tail towers 120 on both sides of the floating box main body 110 respectively, enabling the staff to safely pass through and perform construction operations on the upper channel 300 when the launching barge 100 conducts diving operations. This upper channel 300 adopts a conventional steel structure channel design.

[0041] Further, a dock pier 400 is detachably installed in the middle of the top surface of the floating box main body 110, and the dock pier 400 is symmetrically arranged from the middle to both sides. Specifically, the dock pier 400 is used to stably support the ships entering and leaving the launching barge 100, ensuring that the ships do not deform or displace during the maintenance or launching process. The detachable dock pier 400 enables the adjustment of the position distribution of the dock pier 400 on the floating box main body 110 according to the ship type and weight, ensuring uniform force on different ships. The dock pier 400 is in the form of a conventional steel pier structure.

[0042] In this embodiment, the floating box main body 110 is 95m long, 38.5m wide, and 5.4m high, the tower 120 is 12.5m long, 2.1 / 3.2m wide, and 13.6m high. One floating box main body 110 and four towers 120 form a launching barge 100 with a total height of 16.9m. The temporary floating box 200 is 1.8m wide, 17.5m long, and 7.5m high. The dock pier 400 is about 1.2m high. Two temporary floating boxes 200 are respectively arranged in the middle on both sides of the floating box main body 110 to increase the overall operation stability of the launching barge 100 during the diving and floating stages of the ship repair process, and can meet the functions of launching and repairing small ships below 5000 tons.

[0043] The improvement method of the launching barge in another embodiment of the present invention refers to Figures 2 to 5 and includes the above-mentioned improved structure of the launching barge, and comprises the following steps:

[0044] S1. The launching barge 100 docks at the shore, and the temporary floating box 200 is installed in the middle on both sides of the floating box main body 110 to form a floating dock ship type available for launching and repairing small ships; S2. The launching barge 100 is filled with water and dives, and the ship to be repaired is transported into the launching barge 100. The launching barge 100 drains water and floats out of the water surface, and the ship can be stably maintained on the launching barge 100. S3. After the ship repair is completed, the launching barge 100 is filled with water again and dives, and the ship sails out of the launching barge 100 by itself. In step S1, the temporary floating box 200 is of a detachable structure. In step S1, an upper channel 300 is arranged between the head and tail towers 120 and above the temporary floating box 110 for communicating the head and tail towers 120.

[0045] Specifically, temporary floating boxes 200 are additionally arranged in the middle on both sides of the floating box body 110 of the launching barge to form an overall structural form, effectively assisting in increasing the overall buoyancy and stability of the launching barge 100, and it can be improved into a floating dock to improve the single function of the launching barge 100, enabling it to meet the functions of ship launching and repair at the same time, improving the utilization rate of the launching barge 100, avoiding the idle waste of the shipyard's assets, and meeting the full-load production requirements of the shipyard. The temporary floating box 200 has a simple structure and is a detachable structure, which can be detachably lifted off and restored, facilitating construction and improving the ship repair efficiency. The upper channel 300 enables the staff to pass and carry out construction operations on the upper channel 300 when the launching barge 100 is diving.
