Description

Technical Field

[0001] The invention relates to the technical field of hoisting bracket components, and in particular to a hoisting bracket component and a hoisting method for a ship construction block. Background Art

[0002] The main structure of the ship's upper construction section hoisting and lifting code assembly includes lifting ears, reinforcement plates, connecting bolts and other parts. In the process of ship construction, the upper construction section is usually manufactured in sections in the workshop, and then each section is hoisted to the dock or slipway for assembly through the hoisting and lifting code assembly, which can improve the construction efficiency and reduce the workload of on-site construction. In the process of ship maintenance, it is sometimes necessary to dismantle and replace the upper construction section. The hoisting and lifting code assembly can easily lift the upper construction section from the ship, repair or replace it, and then hoist it back to the ship for installation.

[0003] When it is necessary to lift a ship, the workers need to first weld the lifting lugs to the outer surface of the ship components. When welding the lifting lugs to the outer surface of the ship components, it is necessary to weld for a period of time, dissipate heat from the welding position and the lifting lugs, and then wrap the cables or cloth strips around the circular grooves of the lifting lugs, and then lift them up with a crane for splicing.

[0004] A large amount of heat will be generated during the welding process. If the heat is not dissipated in time, the local temperature of the lifting ear will be too high, which may cause the lifting ear to deform, affecting its dimensional accuracy and performance. In addition, overheating may damage the base material of the lifting ear, such as reducing the strength, hardness and other performance indicators of the base material. Heat dissipation can reduce such damage and extend the service life of the lifting ear. Therefore, when welding the lifting ear and the outer surface of the ship component, the staff needs to dissipate the heat from the welding position and the lifting ear after welding for a period of time. However, this will extend the welding working time. For this reason, the present invention proposes a lifting code assembly and a lifting method for lifting the overall section of a ship.

[0034] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described in combination with the drawings in the embodiments of the present invention. Obviously, the described embodiments are 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.

[0035] The present invention will be further described below in conjunction with the embodiments.

[0036] Example: Refer to Figure 1 , Figure 2 and Figure 4 The present invention provides a technical solution: a ship construction section hoisting code assembly and a hoisting method, comprising: a lifting lug seat 1, a lifting lug sleeve 10 is fixedly installed on the top of the lifting lug seat 1, a flipping clamping mechanism is provided on the inner wall of the lifting lug sleeve 10, a cooling groove 2 is provided on the inner wall of the lifting lug seat 1, ventilation grooves 18 are provided on the opposite sides of the lifting lug seat 1, and a hydraulic cooling mechanism is provided on the inner wall of the lifting lug seat 1;

[0037] The inner wall of the cooling tank 2 is filled with cooling kerosene, and the cooling kerosene in the cooling tank 2 increases the liquid flow heat transfer speed through the hydraulic cooling mechanism. The horizontal height of the cooling tank 2 is lower than the horizontal height of the ventilation groove 18. The inner wall of the ear seat 1 is provided with a water storage tank 3, and the horizontal height of the water storage tank 3 is lower than the horizontal height of the cooling tank 2.

[0038] like Figure 2 and Figure 3 As shown, the inner wall of the ear sleeve 10 is provided with a plurality of spherical engaging grooves 11 , the inner wall of the ear sleeve 10 is provided with a cylinder 12 , and a plurality of engaging balls 13 are fixedly mounted on the outer circumference of the cylinder 12 , and the outer wall of the engaging balls 13 can be engaged with the inner wall of the spherical engaging groove 11 .

[0039] When the lifting lug seat 1 needs to be welded, the staff first injects cooling water from the water inlet tank 31 into the water storage tank 3 until it is full, and then performs welding work. The welding process first welds for a period of time, then cools and finally welds for a period of time. If the hydraulic cooling mechanism is used, the welding process time will be shortened. For example, the normal welding time is to weld for one hour, then cool for half an hour, and finally weld for one hour. If the hydraulic cooling mechanism is used, the welding time is to weld for one and a half hours, then cool for less than half an hour, and finally weld for half an hour. Because the welding time is two hours, but the cooling time is increased to two and a half hours of welding work time, if the hydraulic cooling mechanism is used, the welding time will be less than two and a half hours, thereby improving the efficiency of the ship production process;

[0040] After welding is completed, when the staff is sleeved on the inner wall of the lifting ear sleeve 10, in order to avoid the ship components from rotating or swinging in the air during the lifting process due to sea breeze or other external factors, because the ship assembly site is sometimes outdoors and at the seaside, the staff can put the cloth strip in contact with the inner wall of the lifting ear sleeve 10 in the direction of the vertical line of the connection position between the lifting machine and the lifting cloth strip. This can reduce the swing range of the ship components in the air, thereby avoiding damage caused by collision between components, and also avoiding the risk of excessive swinging of components and hitting employees.

[0041] like Figure 5 , Figure 6 , Figures 9 to 11 As shown, the hydraulic cooling mechanism includes a hydraulic pipe 1 20 and a hydraulic pipe 2 21 fixedly installed on the inner wall of the lifting ear seat 1, the hydraulic pipe 1 20 and the hydraulic pipe 2 21 are connected to one side of the cooling groove 2, the hydraulic pipe 1 20, the hydraulic pipe 2 21 and the cooling groove 2 are in the same plane, the top of the hydraulic pipe 1 20 is connected to the drainage pipe 22, the inner bottom of the drainage pipe 22 is fixedly installed with a one-way piece 1 201, the inner wall of the drainage pipe 22 is airtightly slidably connected with a piston 2 39, the top of the piston 2 39 is fixedly installed with a driving rod 38, the outer wall of the drainage pipe 22 is connected to a connecting pipe 23, the other end of the connecting pipe 23 is connected to the top of the hydraulic pipe 21, and the piston 2 39 moves downward a distance higher than the level of the connecting pipe 23 Height, the connecting pipe 23 is between the one-way piece 1 201 and the piston 2 39, the inner wall of the connecting pipe 23 is fixedly installed with the one-way piece 202, the one-way piece 1 201 and the one-way piece 202 belong to the same component, the inner wall of the one-way piece 1 201 is provided with a conical groove 25, the inner wall of the conical groove 25 is in airtight contact with a conical block 26, and a limiting rod 27 is fixedly installed at the bottom of the conical block 26, the inner wall of the one-way piece 1 201 is provided with an annular groove 24, the annular groove 24 is located directly below the conical groove 25 and are interconnected, the bottom of the one-way piece 1 201 is provided with a liquid groove 28, the liquid groove 28 is located directly below the annular groove 24 and are interconnected, and the limiting rod 27 is located directly below the liquid groove 28.

[0042] When the worker is in the welding process, the heat generated by the ear seat 1 itself due to welding will cause the water storage tank 3 to absorb heat and generate steam. Through the principle of the steam engine, the L-shaped rod 37 starts to move up and down in a cycle. During the process of the L-shaped rod 37 moving up and down in a cycle, the piston 2 39 will be driven to move up and down in the inner wall of the drainage tube 22, and at the same time, the state of the air pressure in the drainage tube 22 being greater than or less than the external air pressure will be switched cyclically. That is, when the air pressure in the drainage tube 22 is less than the external air pressure, the limit rod 27 will move upward and tightly adhere to the drainage tube 22. At the bottom of the one-way piece 201, the conical block 26 then moves upward, so that the space formed by the conical block 26, the conical groove 25, the annular groove 24 and the liquid-passing groove 28 facilitates the cooling kerosene in the hydraulic pipe 20 to move into the drainage pipe 22. At the same time, when the air pressure in the drainage pipe 22 is lower than the external air pressure, the structure of the one-way piece 202 in the connecting pipe 23 is the same as that of the one-way piece 201, and the one-way piece 202 will close the connecting pipe 23 to prevent the cooling kerosene in the hydraulic pipe 21 from entering the drainage pipe 22.

[0043] When the air pressure in the drainage pipe 22 is greater than the external air pressure, the piston 239 moves downward, that is, the conical block 26 moves downward and is tightly attached to the inner wall of the conical groove 25, preventing the kerosene in the hydraulic pipe 20 from freely entering the drainage pipe 22. At the same time, the one-way piece 202 in the connecting pipe 23 opens, and the cold-cut kerosene in the drainage pipe 22 moves into the connecting pipe 23 until it moves into the hydraulic pipe 21, forming a cooling kerosene. In the heat absorption process, the heat transfer effect is improved by increasing the flow rate, overcoming the problem of low heat transfer rate of the cooling kerosene and improving the heat dissipation effect.

[0044] To explain, the limit rod 27 in the one-way member 202 is directed away from the drainage tube 22, so when the one-way member 201 opens the inner wall of the drainage tube 22, the one-way member 202 closes the inner wall of the connecting tube 23. Conversely, when the one-way member 201 closes the inner wall of the drainage tube 22, the one-way member 202 opens the inner wall of the connecting tube 23 using the principle of a one-way valve.

[0045] like Figures 4 to 7 and Fig. 9As shown, a baffle plate 32 is fixedly installed on the inner wall of the ear seat 1, and the baffle plate 32 is located just above the water storage tank 3. The top of the baffle plate 32 is connected to a thermal reaction tube 33. A limit ring 301 is fixedly installed on the inner bottom of the thermal reaction tube 33. A piston 34 is airtightly slidably connected to the inner wall of the thermal reaction tube 33. A spring 35 is fixedly installed on the top of the piston 34. A circular cover plate 36 is fixedly installed on the top of the spring 35. The outer wall of the circular cover plate 36 is fixedly installed on the inner wall of the thermal reaction tube 33. The piston 34, the circular cover plate 36 and the thermal reaction tube 33 are connected to each other. The tube 33 forms an airtight environment, an L-shaped rod 37 is fixedly installed on the top of the piston 34, the inner wall of the spring 35 is sleeved on the outer wall of the rod body of the L-shaped rod 37 which is on the inner wall of the thermal reaction tube 33, one side of the L-shaped rod 37 is fixedly installed on the top of the driving rod 38, one side of the blocking plate 32 is connected to the water pipe 30, the outer wall of the ear seat 1 is provided with a water inlet groove 31, the water inlet groove 31 and the water pipe 30 are connected to each other, and the outer walls on the opposite sides of the ear seat 1 are provided with ventilation grooves 18, and the ventilation grooves 18 are located between the horizontal heights of the drainage pipe 22 and the L-shaped rod 37.

[0046] When the water storage tank 3 is filled with cooling water, the lug seat 1 starts to heat up due to welding, and the cooling water can help cool the kerosene to dissipate heat. At the same time, when the cooling water is heated, steam will appear. Then, according to the principle of the steam engine, the piston 34 will move upward. When the piston 34 rises to a certain distance, the heat reaction tube 33 can contact the outside air through the ventilation groove 18. When the piston 34 encounters the cold air above, it will automatically move downward and drive the L-shaped rod 37 to move up and down in a cycle.

[0047] In order to prevent the heat generated by welding from turning the air in the ventilation groove 18 into hot air, so that the piston 34 cannot contact the cold air, and thus the piston 34 cannot move downward automatically, the spring 35 can be used to allow the piston 34 to move downward automatically. At the same time, in order to prevent the piston 34 from moving downward for too long and the piston 34 cannot continue to be in airtight contact with the inner wall of the thermal reaction tube 33, the piston 34 can be restricted to the inner wall of the thermal reaction tube 33 by its limit ring 301.

[0048] like Figure 2 and Figure 3 As shown, the flip-and-clamp mechanism includes two sleeve rings 14 fixedly installed at both ends of a cylinder 12, the inner wall of the sleeve ring 14 is rotatably connected with an optical axis 15, the outer wall of the shaft body where the optical axis 15 is located between the two sleeve rings 14 is fixedly installed with a flip rod 16, the outer wall of the flip rod 16 is rotatably connected with a clamping arc ring 17, and the opposite side of the ear sleeve 10 is fixedly installed with an arc-shaped clamping rod 19, which can be clamped in the clamping arc ring 17.

[0049] When it is necessary to clamp the cloth strip, the staff sticks the cloth strip on the inner wall of the lifting ear sleeve 10, and then inserts the cylinder 12 into the lifting ear sleeve 10 until the clamping ball 13 is clamped on the inner wall of the spherical clamping groove 11, and then puts the clamping arc ring 17 on the arc clamping rod 19, and then flips the flipping rod 16 downward to allow the cylinder 12 to be tightly clamped on the inner wall of the lifting ear sleeve 10. The truck basket guardrail clamping mechanism is adopted, and the clamping ball 13 is clamped on the inner wall of the spherical clamping groove 11 to avoid the cylinder 12 automatically rotating on the inner wall of the lifting ear sleeve 10 during the lifting of ship components, causing the cloth strip to slide on the inner wall of the lifting ear sleeve 10, and finally causing the ship components to flip over a larger range.

[0050] A method for hoisting a hoisting bracket assembly for a ship-mounted construction section according to claims 1 to 8, characterized in that it comprises the following steps:

[0051] S1. The cooling water is passed from the water inlet tank 31 into the water storage tank 3, and then the bottom of the lug seat 1 is welded to the outer surface of the ship component;

[0052] S2. During the welding process, the cooling water heats up through the steam engine principle, driving the L-shaped rod 37 to move up and down in a cycle, thereby driving the hydraulic cooling mechanism, allowing the cooling kerosene in the cooling tank 2 to improve the heat dissipation effect and increase the welding time;

[0053] S3. After welding, put the cloth strip into the spherical clamping groove 11 according to the angle, then insert the cylinder 12 into the spherical clamping groove 11 to make the cloth strip clamped between the cylinder 12 and the spherical clamping groove 11, and finally make the cloth strip clamped in the spherical clamping groove 11 by flipping the clamping mechanism, which can avoid the lifting and assembly process. If the ship component sways due to wind or other reasons, the swaying range of the ship component can be avoided.

[0054] Working principle: when it is necessary to weld the lifting lug seat 1, the staff first injects cooling water from the water inlet tank 31 into the water storage tank 3 until it is full, and then performs welding work. When the staff is in the welding process, the heat generated by the lifting lug seat 1 itself due to welding will cause the water storage tank 3 to absorb heat and generate steam, and the L-shaped rod 37 starts to move up and down in a cycle through the principle of the steam engine. During the process of the L-shaped rod 37 moving up and down in a cycle, the second piston 39 will be driven to move up and down in the inner wall of the drainage tube 22, and at the same time, the state of the air pressure in the drainage tube 22 being greater than or less than the external air pressure will be switched in a cycle. By switching the state of the air pressure in the drainage tube 22 being greater than or less than the external air pressure, when the one-way piece 1 201 opens the inner wall of the drainage tube 22, the one-way piece 202 closes the inner wall of the connecting tube 23. On the contrary, when the one-way piece 1 201 closes the inner wall of the drainage tube 22, the one-way piece 202 opens the inner wall of the connecting tube 23.

[0055] When the cloth strip needs to be clamped, the staff sticks the cloth strip on the inner wall of the ear sleeve 10, and then inserts the cylinder 12 into the ear sleeve 10 until the clamping ball 13 is clamped on the inner wall of the spherical clamping groove 11, and then puts the clamping arc ring 17 on the arc clamping rod 19, and then flips the flip rod 16 downward to allow the cylinder 12 to be tightly clamped on the inner wall of the ear sleeve 10.

[0056] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements will not cause the essence of the corresponding technical solutions to deviate from the protection scope of the technical solutions of the embodiments of the present invention.
