Description

Technical Field

[0001] This invention relates to the field of shipbuilding technology, specifically to a tooling for excavating insulation in ships and its usage method. Background Technology

[0002] During the construction and use of ships, many rooms require fireproofing and moisture-proofing measures, necessitating insulation work. Where conduits pass through, insulating rubber or similar materials are used for covering. In ship design, some rooms inevitably have numerous pipe runs. For example, patent publication number CN110816757B discloses a liquid cargo transport pipeline on a chemical tanker. This pipeline includes a pipe and at least one pair of elongated electrodes wrapped in an insulating film, mounted on the inner or outer wall of the pipe. A sleeve is fitted over the outside of the liquid cargo transport pipeline.

[0003] These pipes, passing through various rooms, create gaps and leaks that must be sealed for shipboard tightness, without obstructing the passage of the conduits. Therefore, during ship construction, pipe openings need to be pre-drilled in the walls of these rooms. When laying insulation in these rooms, these pipe openings are laid along with the insulation, thus sealing the pre-drilled openings. When the project progresses to pipe laying, holes need to be excavated at the pre-drilled pipe openings to create appropriately sized holes. Traditional excavation methods involve using a utility knife to cut rectangular or near-circular holes in the insulation. This method is not only wasteful of manpower and resources and time, but also produces unsightly and unpleasantly cut insulation ends, failing to ensure the excavated openings are flush with the pipe wall. Therefore, practical operation necessitates a device capable of rapidly excavating insulation to meet this technical requirement. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention provides a tooling system for excavating insulators on ships and a method for excavating insulator holes. This solves the problems of existing methods requiring manual excavation of insulators, which not only wastes manpower and resources but also results in uneven and unsightly excavated insulator ports that cannot be properly fitted to pipe walls.

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

[0006] A tooling for excavating insulators on ships includes a horizontally mounted mounting plate. A propulsion motor is mounted above the mounting plate, and a horizontally mounted propulsion screw is mounted at the output end of the propulsion motor. In a preferred embodiment, a reducer is provided between the output end of the propulsion motor and the propulsion screw to reduce the output speed of the propulsion motor, causing the propulsion motor to drive the propulsion screw to rotate slowly. Then, through the threaded engagement between the propulsion screw and the nut seat, the propulsion plate drives the rotating disk and the digging cutter assembly to move slowly, thereby gradually deepening the digging depth. Fixed plates extending along the length direction of the propulsion screw are fixedly mounted on both sides of the propulsion screw. A horizontal propulsion plate is slidably mounted between the two fixed plates. A nut seat threadedly engaged with the propulsion screw is fixedly mounted on the bottom of the propulsion plate. A drive motor is fixedly mounted on the upper surface of the propulsion plate away from the propulsion motor. A rotating disk is fixedly mounted on the output end of the drive motor through a connecting part. The digging cutter assembly is movably mounted on the side of the rotating disk away from the drive motor.

[0007] A vertical support rod is mounted on one bottom end of the mounting plate via a movable connecting shaft assembly. A lifting hydraulic cylinder is fixedly connected to the bottom of the support rod. An adjusting hydraulic cylinder is mounted between the other bottom end of the mounting plate and the bottom of the support rod via a movable connecting shaft assembly.

[0008] Preferably, the inner side of the fixed plate is provided with a guide groove extending along the length direction of the push screw, and the two sides of the push plate are provided with guide strips that slide in cooperation with the guide groove. With this configuration, the push plate can move horizontally along the guide groove through the sliding cooperation of the guide groove and the guide strips, thereby enabling the rotary disk to move linearly along the guide groove, so that the digging blade assembly can dig through the insulator.

[0009] Preferably, the connecting part is a circular ring structure, which can fix the output end of the drive motor to the center of the rotating disk. This configuration allows the connecting part to fix the output end of the drive motor and the connecting ring at the center of the rotating disk together.

[0010] Preferably, the rotating disk includes a connecting ring and a fixing ring arranged coaxially. A fixing rod is fixedly connected between the connecting ring and the fixing ring. There are three fixing rods, evenly distributed on the inner side of the fixing ring. The fixing rods securely fix the connecting ring and the fixing ring together, making the rotating disk more robust and reliable as a whole.

[0011] Preferably, the surface of the fixed rod is provided with a movable groove extending along the axis of the rotating disk, the cross-section of the movable groove is a T-shaped structure, and the bottom of the movable groove is provided with a through groove extending along the axis of the rotating disk.

[0012] Preferably, the excavating cutter assembly includes a slider that slides into the moving slot. An arc-shaped cutter is fixedly mounted on the front side of the slider, and a fastening bolt is mounted on the rear side of the slider via a bearing. The fastening bolt extends out of the through slot, and a wing nut is threaded onto the outer side of the fastening bolt. With this configuration, during use, the slider is moved within the moving slot according to the scale value, moving it to the appropriate position according to the requirement of D+20mm. Tightening the wing nut, through the threaded engagement between the wing nut and the fastening bolt, limits and fixes the excavating cutter assembly.

[0013] Preferably, a scale value is provided on one side of the movable groove. By setting the scale value, the position of the arc-shaped cutter can be precisely controlled, thereby precisely controlling the diameter of the excavated insulating port, so that the insulating port can fit more closely to the outer wall of the pipe.

[0014] Preferably, the bottom of the lifting hydraulic cylinder is threaded with a base. During use, a heavy object can be used to press down on the base, ensuring the device is stably fixed at the location to be excavated from the insulator.

[0015] Preferably, the movable connecting shaft assembly includes two fixed plates, with a rotatable connecting shaft positioned between them. By providing the connecting shaft, the top of the support rod and both ends of the adjusting hydraulic cylinder can rotate flexibly, thereby adjusting the tilt angle of the rotating disk.

[0016] A method of using a ship insulation excavation fixture, applied to the aforementioned ship insulation excavation fixture, the method comprising the following steps:

[0017] S1: Measure the diameter D of the pipes in the rooms of the ship that require the installation of insulating materials;

[0018] S2: Move the slider in the moving groove, and use the scale value to move the slider to the appropriate position according to the requirement of D+20mm. Tighten the wing nut, and use the thread engagement between the wing nut and the fastening bolt to limit and fix the digging tool assembly.

[0019] S3: Start the lifting hydraulic cylinder and the adjusting hydraulic cylinder. Adjust the height of the rotating disk by extending and retracting the lifting hydraulic cylinder, and adjust the tilt angle of the rotating disk by extending and retracting the adjusting hydraulic cylinder, so that the rotating disk faces the position to be excavated.

[0020] S4: Start the drive motor and propulsion motor. The drive motor drives the digging cutter set to rotate at high speed through the rotary table. The high-speed rotating digging cutter set digs into the rubber insulator. At the same time, the motor drives the propulsion screw to rotate. Through the threaded engagement between the propulsion screw and the nut seat, the nut seat drives the drive motor and rotary table to move through the propulsion plate, thereby pushing the digging cutter set forward to dig until the rubber insulator of the room is dug through.

[0021] This invention provides a tooling and method for excavating insulators on ships, which has the following beneficial effects:

[0022] 1. This invention uses a drive motor to drive a rotating disk to rotate at high speed, which in turn drives the digging blade assembly to rotate rapidly. The high-speed rotating digging blade assembly is used to dig through the insulator at the reserved pipe opening. At the same time, a propulsion motor drives the propulsion screw to rotate. The cooperation between the propulsion screw and the nut seat causes the propulsion plate to move the rotating disk, thereby enabling the digging blade assembly to gradually dig through the insulator.

[0023] 2. This invention can adjust the height of the rotating disk and the digging cutter assembly by lifting the hydraulic cylinder. By adjusting the cooperation between the hydraulic cylinder and the support rod, the tilt angle of the rotating disk and the digging cutter assembly can be adjusted so that the rotating disk and the digging cutter assembly are aligned with the insulator to be excavated, so that the device can excavate the insulator at the reserved pipe opening at different angles.

[0032] Example 1

[0033] Please see Figure 1-5 This embodiment provides a tooling for excavating insulators on a ship, comprising a horizontally mounted mounting plate 4, a propulsion motor 5, a rotary disk 11, and an excavating cutter assembly 12. The propulsion motor 5 is mounted above the mounting plate 4, and a horizontally mounted propulsion screw 6 is mounted at the output end of the propulsion motor 5. In a preferred embodiment, a speed reducer is provided between the output end of the propulsion motor 5 and the propulsion screw 6. The speed reducer lowers the output speed of the propulsion motor 5, causing the propulsion motor 5 to drive the propulsion screw 6 to rotate slowly. Furthermore, through the threaded engagement between the propulsion screw 6 and the nut seat 13, the propulsion plate 8 drives the rotary disk 11 and the excavating cutter assembly 12 to move slowly, thereby gradually deepening the excavation depth.

A horizontal push plate 8 is slidably installed between the two fixed plates 7. A nut seat 13 that is threadedly engaged with the push screw 6 is fixedly installed at the bottom of the push plate 8. A drive motor 9 is fixedly installed at the end of the upper surface of the push plate 8 away from the push motor 5. A rotating disk 11 is fixedly installed at the output end of the drive motor 9 through a connecting part 10. A digging blade assembly 12 is movably installed on the side of the rotating disk 11 away from the drive motor 9.

The fixing rods 1102 securely fix the connecting ring 1105 and the fixing ring 1101 together, making the rotating disk 11 more robust and reliable as a whole.

[0039] In this embodiment, the surface of the fixed rod 1102 is provided with a moving groove 1103 extending along the axis of the rotating disk 11. The cross-section of the moving groove 1103 is a T-shaped structure, and the bottom of the moving groove 1103 is provided with a through groove 1104 extending along the axis of the rotating disk 11.

[0040] In this embodiment, the excavating cutter assembly 12 includes a slider 1201 that slides into the moving groove 1103. An arc-shaped cutter 1203 is fixedly mounted on the front side of the slider 1201, and a fastening bolt 1204 is mounted on the rear side of the slider 1201 via a bearing. The fastening bolt 1204 extends out of the through groove 1104, and a wing nut 1205 is threaded onto the outer side of the fastening bolt 1204. With this configuration, during use, the slider 1201 is moved within the moving groove 1103, and in accordance with the scale value 16, the slider 1201 is moved to the appropriate position according to the requirement of D+20mm. The wing nut 1205 is then tightened, and the threaded engagement between the wing nut 1205 and the fastening bolt 1204 limits and fixes the excavating cutter assembly 12.

[0041] In this embodiment, a scale value 16 is provided on one side of the moving groove 1103. By setting the scale value 16, the position of the arc-shaped cutter 1203 can be precisely controlled, thereby precisely controlling the diameter of the excavated insulating port, so that the insulating port can fit more closely to the outer wall of the pipe.

[0042] In this embodiment, a base 14 is threadedly installed at the bottom of the lifting hydraulic cylinder 1. During use, the base 14 can be pressed down by a heavy object, so that the device can be stably fixed at the position to be excavated on the insulator.

[0043] In this embodiment, the movable connecting shaft assembly 15 includes two fixed plates, and a rotatable connecting shaft is provided between the two fixed plates. By setting the connecting shaft, the top of the support rod 2 and both ends of the adjusting hydraulic cylinder 3 can rotate flexibly, thereby adjusting the tilt angle of the rotating disk 11.

[0044] Example 2

[0045] This embodiment describes a method for excavating insulators on a ship, utilizing the aforementioned insulator excavation fixture as a specialized tool. The method includes the following steps:

[0046] S1: Measure the diameter D of the pipes in the rooms of the ship that require the installation of insulating materials;

[0047] S2: Move the slider 1201 in the moving groove 1103, and use the scale value 16 to move the slider 1201 to the appropriate position according to the requirement of D+20mm. Tighten the wing nut 1205, and limit and fix the digging tool assembly 12 through the thread engagement between the wing nut 1205 and the fastening bolt 1204.

[0048] S3: Start the lifting hydraulic cylinder 1 and the adjusting hydraulic cylinder 3. Adjust the height of the rotating disk 11 by extending and retracting the lifting hydraulic cylinder 1, and adjust the tilt angle of the rotating disk 11 by extending and retracting the adjusting hydraulic cylinder 3, so that the rotating disk 11 is facing the excavation position.

[0049] S4: Start the drive motor 9 and the propulsion motor 5. The drive motor 9 drives the digging cutter group 12 to rotate at high speed through the rotary disk 11. The high-speed rotating digging cutter group 12 digs the rubber insulator. At the same time, it drives the motor to drive the propulsion screw 6 to rotate. Through the threaded engagement between the propulsion screw 6 and the nut seat 13, the nut seat 13 drives the drive motor 9 and the rotary disk 11 to move through the propulsion plate 8, thereby pushing the digging cutter group 12 forward to dig until the rubber insulator of the room is dug through.

[0050] S5: After excavating an insulating hole, move to other locations for subsequent excavation. During excavation, simply adjust the size of the excavation cutter group 12 according to the corresponding location to meet the requirements.
