Description

Technical Field

[0001] This utility model relates to the field of aircraft maintenance technology, and in particular to a temporary sealing device for industrial pipeline maintenance. Background Technology

[0002] Industrial pipelines often experience leaks or damage due to corrosion, wear, aging, and other reasons during long-term use. Temporary sealing measures are required when repairing pipelines to prevent media leakage or contamination.

[0003] While some existing sealing devices can provide a certain sealing effect through mechanical means, they require manual fixing and disassembly, which is time-consuming and labor-intensive. This is especially true when the pipeline pressure is high or the space is confined, making operation even more difficult. Furthermore, different sizes of pipelines require different sealing devices, and existing devices can only be adapted to one size of pipeline, resulting in poor versatility and increased usage costs. Utility Model Content

[0004] To address the technical problems of existing technologies that require manual fixing and disassembly of sealing devices, which is time-consuming and labor-intensive, and can only be used with pipes of one size, resulting in poor versatility and increased usage costs, this utility model provides a temporary sealing device for industrial pipeline maintenance.

[0005] The technical solution adopted by this utility model is: a temporary sealing device for industrial pipeline maintenance, including a first mounting frame, a second mounting frame, and a sealing plate. An electric push rod is fixedly installed on one side of the second mounting frame. A fixing component is installed between the first mounting frame and the second mounting frame to fix the sealing plate inside the pipeline. The fixing component includes a first motor fixedly installed inside the first mounting frame and abutment plates installed on both sides of the second mounting frame. A connecting plate is fixedly installed at one end of the electric push rod. The connecting plate has a disassembly and assembly component that facilitates quick installation and removal of the sealing plate. The fixing component can fix the sealing plate in the inner wall of the pipeline, improving its stability and sealing performance. The disassembly and assembly component can quickly install or remove the sealing plate, facilitating its replacement.

[0006] Furthermore, a first threaded rod is fixedly installed at the output end of the first motor, and the other end of the first threaded rod is rotatably connected to one side of the second mounting frame. A movable plate is threadedly connected to the surface of the first threaded rod, and two symmetrical hinge rods are hinged to one side of the movable plate. The other ends of the two hinge rods are respectively hinged to one side of the two abutment plates. The first motor drives the first threaded rod to rotate, causing the movable plate to move along the threaded rod. Through the linkage design of the hinge rods and the abutment plates, the abutment plates on both sides can be retracted or extended.

[0007] Furthermore, a sliding rod is fixedly installed at one end of each of the two abutments. The two sliding rods pass through one side of the second mounting frame and are slidably connected to the second mounting frame. A limiting plate is fixedly installed at one end of each of the two sliding rods. The limiting plate is slidably connected inside the second mounting frame. The combination of the sliding rod and the limiting plate ensures the stability of the abutments during movement, prevents them from falling out, and improves the safety and reliability of the device.

[0008] Furthermore, two symmetrical telescopic rods are fixedly installed between the first mounting frame and the movable plate, which can limit the movement of the movable plate.

[0009] Furthermore, silicone pads are fixedly installed on the outer surfaces of both abutments. The installation of silicone pads can effectively protect the inner wall of the pipe, prevent the abutments from damaging the pipe during the fixing process, and increase friction to improve the fixing effect.

[0010] Furthermore, the disassembly and assembly assembly includes a second motor fixedly installed inside the connecting plate. A first bevel gear is fixedly installed at the output end of the second motor. Second bevel gears mesh with the upper and lower surfaces of the first bevel gear. A second threaded rod is fixedly installed on one side of each of the two second bevel gears. The second threaded rod is rotatably connected inside the connecting plate. A snap-fit ​​plate is threadedly connected to the surface of each of the two second threaded rods. The two snap-fit ​​plates pass through the upper and lower sides of the connecting plate and are slidably connected to the connecting plate. Two symmetrical snap-fit ​​frames that fit with the snap-fit ​​plates are fixedly installed on the back of the sealing plate. The second motor drives the first bevel gear, and the first bevel gear drives the two second bevel gears on both sides to rotate synchronously. Through the cooperation of the two second threaded rods, the snap-fit ​​plates can be inserted into or disengaged from the snap-fit ​​frames.

[0011] Furthermore, a handle is fixedly installed on one side of the first mounting frame, making the device easier to operate and move, thus improving its portability.

[0012] The beneficial effects of this utility model are:

[0013] 1. This utility model, through the setting of fixing components, can fix the sealing plate in the inner wall of the pipeline, thereby improving its stability and sealing performance. It solves the problem that although some existing sealing devices can provide a certain sealing effect through mechanical devices, they require manual fixing and disassembly of the sealing device, which is time-consuming and labor-intensive, especially when the pipeline pressure is high or the space is narrow, making the operation even more difficult.

[0014] 2. Secondly, through the design of the disassembly and assembly components, the sealing plate can be quickly installed or disassembled, making it easy to replace. This solves the problem that existing sealing devices can only be adapted to one size of pipe, resulting in poor versatility and increased usage costs. Attached Figure Description

[0022] The following is in conjunction with Figure 1- Figure 4 The present invention will be further described below.

[0023] To address the problems existing in the background technology, this application proposes the following technical solution: a temporary sealing device for industrial pipeline maintenance.

[0024] The specific technical solution includes a first mounting frame 1, a second mounting frame 2, and a sealing plate 3. An electric push rod 4 is fixedly installed on one side of the second mounting frame 2. A fixing component 5 is installed between the first mounting frame 1 and the second mounting frame 2 to fix the sealing plate 3 inside the pipe. The fixing component 5 includes a first motor 501 fixedly installed inside the first mounting frame 1 and abutment plates 505 installed on both sides of the second mounting frame 2. A connecting plate 6 is fixedly installed at one end of the electric push rod 4. A disassembly and assembly component 7 is installed inside the connecting plate 6 to facilitate quick installation and removal of the sealing plate 3. Through the setting of the fixing component 5, the sealing plate 3 can be fixed in the inner wall of the pipe, improving the stability and sealing performance of the sealing. The design of the disassembly and assembly component 7 realizes the quick installation and removal of the sealing plate 3, which is convenient for sealing pipes of different sizes.

[0025] Referring to Figures 1 and 2, a first threaded rod 502 is fixedly installed at the output end of the first motor 501. The other end of the first threaded rod 502 is rotatably connected to one side of the second mounting frame 2. A movable plate 503 is threadedly connected to the surface of the first threaded rod 502. Two symmetrical hinge rods 504 are hinged to one side of the movable plate 503. The other ends of the two hinge rods 504 are respectively hinged to one side of two abutment plates 505. A sliding rod 506 is fixedly installed at one end of each abutment plate 505. The two sliding rods 506 pass through one side of the second mounting frame 2 and are slidably connected to the second mounting frame 2. A limit plate 507 is fixedly installed at one end of each sliding rod 506. The limit plate 507 is slidably connected inside the second mounting frame 2. Two symmetrical telescopic rods 508 are fixedly installed between the first mounting frame 1 and the movable plate 503. Silicone pads 509 are fixedly installed on the outer surfaces of the two abutment plates 505. The first motor 501 drives the first threaded rod 502. Rotation occurs because the first threaded rod 502 is threadedly connected to the movable plate 503, and the movable plate 503 is limited by two telescopic rods 508. Therefore, the movable plate 503 will move along the threaded rod. The movement of the movable plate 503 will cause the hinge rod 504 to swing, thereby pushing the two abutment plates 505 to unfold outward. The outer surface of the abutment plate 505 is equipped with a silicone pad 509, which can increase friction and protect the inner wall of the pipe. The movement of the abutment plate 505 simultaneously causes the sliding rod 506 to slide within the second mounting frame 2. The limiting plate 507 ensures that the sliding rod 506 will not come out, maintaining structural stability.

[0026] Refer to Figures 1 and 3. Figure 4As shown, the disassembly and assembly assembly 7 includes a second motor 701 fixedly installed inside the connecting plate 6. A first bevel gear 702 is fixedly installed at the output end of the second motor 701. Second bevel gears 703 are meshed on both the upper and lower surfaces of the first bevel gear 702. A second threaded rod 704 is fixedly installed on one side of each of the two second bevel gears 703. The second threaded rod 704 is rotatably connected inside the connecting plate 6. A snap-fit ​​plate 705 is threadedly connected to the surface of each of the two second threaded rods 704. The two snap-fit ​​plates 705 pass through the upper and lower sides of the connecting plate 6 and are slidably connected to the connecting plate 6. Two symmetrical snap-fit ​​frames 706 that fit with the snap-fit ​​plates 705 are fixedly installed on the back of the sealing plate 3. A handle 8 is fixedly installed on one side of the first mounting frame 1. The second motor 701 drives the first bevel gear 702 to rotate. The first bevel gear 702 meshes with the two second bevel gears 703, causing the two second bevel gears 703 to rotate synchronously. The second bevel gears 703 drive the second threaded rod 704 to rotate. Since the second threaded rod 704 is threadedly connected to the snap-fit ​​plate 705, the snap-fit ​​plate 705 moves up and down along the threaded rod and finally inserts into the snap-fit ​​frame 706 on the back of the sealing plate 3 to install and fix the sealing plate 3.

[0027] To ensure that those skilled in the art can fully understand the technical solution, this application provides the following overall overview:

[0028] When using it, first select the appropriate sealing plate 3 according to the size of the inner wall of the pipe, and then start the second motor 701 to drive the first bevel gear 702 to rotate. The first bevel gear 702 meshes with two second bevel gears 703, causing the two second bevel gears 703 to rotate synchronously. The second bevel gears 703 drive the second threaded rod 704 to rotate. Since the second threaded rod 704 is threadedly connected to the snap-fit ​​plate 705, the snap-fit ​​plate 705 moves up and down along the threaded rod and finally inserts into the snap-fit ​​frame 706 on the back of the sealing plate 3 to install and fix the sealing plate 3. Then, the worker picks up the handle 8 and inserts the sealing plate 3 into the inner wall of the pipe. The electric push rod 4 is activated to move the sealing plate 3 to the designated position. Then, the first motor 501 is activated to drive the first threaded rod 502 to rotate. Since the first threaded rod 502 is threadedly connected to the moving plate 503 and the moving plate 503 is limited by the two telescopic rods 508, the moving plate 503 will move along the threaded rod. The movement of the moving plate 503 will drive the hinge rod 504 to swing, thereby pushing the two abutment plates 505. Extend it outwards until it touches the inner wall of the pipe.
