Description

Technical Field

[0001] This utility model relates to the technical field of ship piping installation devices, specifically to an auxiliary tool for disassembling and assembling flange gaskets in ship piping systems. Background Technology

[0002] In shipbuilding and repair engineering, piping systems are a crucial component. The reliability and sealing of their connections are directly related to the operational safety of the ship. Butt flanges are a common connection method in piping systems, while gaskets are key components to ensure the sealing of flange connections. During the daily maintenance or repair of ships, it is often necessary to replace aging or damaged gaskets.

[0003] Currently, the disassembly and assembly of flange gaskets, especially when the gap between the two flanges is extremely small or there is a slight misalignment, is generally done manually using simple tools such as pry bars and files to forcibly pry them open. This method is not only inefficient and labor-intensive, but also very easy to injure operators due to improper operation. Therefore, the existing technology has the problems of being difficult to operate, time-consuming and labor-intensive, and posing safety hazards.

[0004] To address this, we propose an auxiliary tool for the installation and removal of flange gaskets in ship piping systems. Utility Model Content

[0005] The purpose of this utility model is to address the shortcomings of existing technologies by proposing an auxiliary tool for disassembling and assembling flange gaskets in ship piping systems.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: An auxiliary tool for disassembling and assembling flange gaskets in ship piping systems, comprising: a base; The disassembly and assembly mechanism includes a mounting bracket fixedly connected to the upper end of the base. The mounting bracket has a sliding groove on its side wall, a slider is slidably connected to the inner wall of the sliding groove, an electric push rod is fixedly connected to the side wall of the slider, an installation block is fixedly connected to the movable end of the electric push rod, an installation groove is provided on the side wall of the installation block, and a support plate is symmetrically slidably connected to the inner wall of the installation groove.

[0007] Preferably, the disassembly and assembly mechanism further includes a bidirectional lead screw rotatably connected to the inner wall of the mounting groove, the side wall of the bidirectional lead screw being threadedly connected to two support plates, and a servo motor being fixedly connected to the side wall of the mounting block, the output end of the servo motor passing through the side wall of the mounting block and being fixedly connected to the bidirectional lead screw.

[0008] Preferably, a lead screw is rotatably connected to the inner wall of the slide, the side wall of the lead screw is threadedly connected to the slider, and a second servo motor is fixedly connected to the upper end of the mounting bracket. The output end of the second servo motor passes through the upper end of the mounting bracket and is fixedly connected to the lead screw.

[0009] Preferably, a fixing mechanism is installed on the base, the fixing mechanism includes a fixing frame fixedly connected to the upper end of the base, cylinders are symmetrically fixedly connected to the side wall of the fixing frame, and a fixing plate is fixedly connected to the movable end of the cylinder after passing through the inner wall of the fixing frame.

[0010] Preferably, the inner wall of the fixing frame and the side wall of the fixing plate are coated with a smooth coating, and the smooth coating is made of polytetrafluoroethylene.

[0011] Preferably, the bottom of the fixing frame is provided with a slot.

[0012] This utility model has the following beneficial effects: 1. By setting up a disassembly and assembly mechanism, the support plate is driven by power components such as servo motors and electric push rods to perform precise movement and opening operations. The automation level is high, which completely replaces the traditional heavy operation that relies entirely on manpower. Operators only need to control the servo motor to complete the opening and resetting of the flange, which greatly saves manpower and time, and reduces labor intensity and operation skill threshold. 2. By setting a lead screw and a second servo motor, the height of the support plate can be adjusted by starting the second servo motor, which facilitates the installation and removal of flange gaskets for different specifications of ship connecting pipes, thus expanding the range of applications.

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0016] Reference Figures 1-4 An auxiliary tool for disassembling and assembling flange gaskets in ship piping systems, comprising: a base 1; The disassembly and assembly mechanism includes a mounting bracket 2 fixedly connected to the upper end of the base 1. The side wall of the mounting bracket 2 has a sliding groove 3. A slider 4 is slidably connected to the inner wall of the sliding groove 3. An electric push rod 5 is fixedly connected to the side wall of the slider 4. The electric push rod 5 is of model DTZ-100. An installation block 6 is fixedly connected to the movable end of the electric push rod 5. An installation groove 7 is opened on the side wall of the installation block 6. A support plate 8 is symmetrically slidably connected to the inner wall of the installation groove 7. An inclined wedge surface is provided on the outer side of the support plate 8. This tool is suitable for disassembling and assembling flange gaskets of medium and low pressure, small diameter marine piping systems.

[0017] The disassembly and assembly mechanism also includes a bidirectional lead screw 10 rotatably connected to the inner wall of the mounting groove 7. The side wall of the bidirectional lead screw 10 is threadedly connected to two support plates 8. A servo motor 9 is fixedly connected to the side wall of the mounting block 6. The output end of the servo motor 9 passes through the side wall of the mounting block 6 and is coaxially fixed with the bidirectional lead screw 10. The servo motor 9 is existing technology and will not be described in detail here.

[0018] A lead screw 11 is rotatably connected to the inner wall of the slide 3. The side wall of the lead screw 11 is threadedly connected to the slider 4. A servo motor 12 is fixedly connected to the upper end of the mounting bracket 2. The output end of the servo motor 12 can rotate in both directions. The output end of the servo motor 12 passes through the top inner wall of the mounting bracket 2 and is fixedly connected to the lead screw 11.

[0019] A fixing mechanism is installed on the base 1. The fixing mechanism includes a fixing frame 13 fixedly connected to the upper end of the base 1. The bottom of the fixing frame 13 has a slot. Cylinders 14 are symmetrically fixedly connected to the side walls of the fixing frame 13. Cylinders 14 are existing technology and will not be described in detail here. The movable end of the cylinder 14 passes through the inner wall of the fixing frame 13 and is fixedly connected to a fixing plate 15. The inner wall of the fixing frame 13 and the side wall of the fixing plate 15 are both coated with a smooth coating. The smooth coating is made of polytetrafluoroethylene (PTFE) material, which has self-lubricating properties and can significantly reduce frictional resistance. It can reduce the friction between the inner wall of the fixing frame 13, the fixing plate 15 and the connecting pipe. The fixing mechanism provides radial clamping force to the connecting pipe, but does not restrict its axial movement, so that when the flange is pried open, the connecting pipe can slide slightly axially to avoid bending stress.

[0020] In this invention, the ship piping connector is placed on the fixed frame 13, with the central connecting flange located at the slot of the fixed frame 13. Then, the cylinder 14 is activated to move the fixed plate 15, so that the fixed plate 15 clamps and fixes the connector to the inner wall of the fixed frame 13. The servo motor 12 is activated to drive the lead screw 11 to rotate, which in turn drives the slider 4 to move up or down. The slider 4 will drive the mounting block 6 to move through the electric push rod 5, which in turn drives the two support plates 8 to move to a suitable height.

[0021] Next, the electric push rod 5 is activated, which moves the mounting block 6 and in turn moves the two support plates 8 closer to the connecting pipe. The two support plates 8 are placed on the outer end faces of the flanges on both sides. By expanding outward, the two flanges are axially opened to form a gap. Then, the servo motor 9 is activated, which drives the bidirectional lead screw 10 to rotate. This allows the two support plates 8 to move away from each other. Under the action of the support plates 8, the connecting flanges of the connecting pipe can be opened to a sufficiently large gap, so that gaskets can be installed or removed between the connecting flanges. Compared with the existing method of manually opening the connecting flanges with a file, this method is more time-saving, labor-saving, and easier to operate.

[0022] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
