Description

Technical Field

[0001] This invention relates to the field of fume extraction duct technology, specifically to a support and hanger for the fume extraction duct of a generator set's oil tank and its installation method. Background Technology

[0002] The oil tank exhaust duct support is specifically designed for the oil tank exhaust system of the generator set. It aims to provide stable support and effective duct fixation. The support is made of high-strength, high-temperature resistant, and corrosion-resistant materials (such as stainless steel and alloys), which can maintain its structural stability under long-term high-temperature environments.

[0003] Chinese patent CN217381926U discloses a support bracket for installing a smoke exhaust duct, including a hanging plate, a first hanging rod, and a second hanging rod. A sleeve is installed at the bottom end of the first hanging rod, and a sleeve is fitted onto the bottom end of the sleeve, which is fixedly connected to the second hanging rod. A tension spring is installed at the bottom end of the sleeve, and the other end of the tension spring is fixed to the bottom end of the inner wall of the sleeve. A first sliding groove is formed on one side of the sleeve, and a sliding rod is slidably connected to the inner side of the first sliding groove. One side of the sliding rod is fixed to the sleeve, and a sliding ring is installed at the other end of the sliding rod, sliding with the sleeve. This patent, through the use of the tension spring, sleeve, and sleeve, allows the relative tensile sliding length of the sleeve and sleeve to determine the force on each hanger after the hanger structure and smoke exhaust duct are installed. This facilitates subsequent force adjustment, ensuring uniform force on all hangers and thus guaranteeing the stability of the smoke exhaust duct and hangers.

[0004] However, the current exhaust duct support and hanger have the following problems: when the support and hanger are used to pull the exhaust duct at a high position, it is necessary to manually pull the exhaust duct through the support and hanger. This can cause the exhaust duct to fall from a height due to the worker's slip, thus damaging the exhaust duct. At the same time, pulling the exhaust duct at a height requires a certain amount of strength and precision. Manual operation can lead to improper operation, which affects the installation quality of the exhaust duct. Therefore, we propose a support and hanger for the exhaust duct of the unit's oil tank and a hoisting method. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides a support and hanger for the exhaust duct of a generator oil tank and a hoisting method, thus solving the problems mentioned in the background section.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a support bracket for an oil tank exhaust duct of a generator set, comprising an outer wall panel, a support frame fixedly connected to the side of the outer wall panel, a fixing ring fixedly connected to the inner wall of the support frame, four L-shaped blocks fixedly connected to the side of the support frame, long blocks fixedly connected to the side of each of the four L-shaped blocks, a hollow frame fixedly connected between every two long blocks, a motor fixedly connected to the bottom of the inner wall of the hollow frame, a threaded rod fixedly connected to the output shaft of the motor, a threaded sleeve threadedly connected to the outer wall of the threaded rod, an electric push rod fixedly connected to the side of the threaded sleeve, an arc block fixedly connected to the telescopic end of the electric push rod, an air pump fixedly connected to the outer wall of the arc block, and a fixed ring fixedly connected to the inner wall of the arc block. A vacuum suction cup is fixedly connected. Since the outer wall of one end of the exhaust duct is not folded, first pass one end of the exhaust duct through the fixing ring so that one end of the exhaust duct is parallel to the arc block. Then, start the electric push rod. The telescopic end of the electric push rod will push the arc block to move towards the exhaust duct, so that the arc block contacts the outer wall of the exhaust duct. At this time, the air pump will cause the vacuum suction cup to adsorb the exhaust duct, thus fixing the exhaust duct. Then, the operator starts the motor. The output shaft of the motor will rotate the threaded rod. The rotation of the threaded rod will move the threaded sleeve upward. The upward movement of the threaded sleeve will drive the electric push rod upward. The upward movement of the electric push rod will drive the arc block upward. The upward movement of the arc block will drive the exhaust duct upward.

[0007] According to the above technical solution, a touch plate is fixedly connected to the bottom of the arc block, and an anti-pressure plate is fixedly connected to the top of the fixed ring. When the arc block moves towards the direction of the exhaust duct, it will drive the touch plate to move. During the movement of the touch plate, it will be blocked by the anti-pressure plate.

[0008] According to the above technical solution, the anti-pressure plate is located on the displacement trajectory of the touch plate, and the distance between the touch plate and the inner arc surface of the arc block is equal to the width of the anti-pressure plate. The anti-pressure plate plays a protective role, preventing the arc block from applying excessive pressure to the exhaust pipe and preventing the exhaust pipe from deforming or being damaged due to excessive pressure during clamping. Especially when the exhaust pipe material is relatively fragile or easily deformed, this design helps to extend the service life of the pipe. Since the distance between the anti-pressure plate and the touch plate and the inner arc surface of the arc block is precisely designed, it can ensure that the exhaust pipe is in a stable state during clamping, thereby reducing the shaking or loosening of the exhaust pipe caused by unstable displacement or uneven pressure.

[0009] According to the above technical solution, the side of the support frame is provided with an anti-shake device, which includes a T-shaped block. The side of the T-shaped block is fixedly connected to the side of the support frame. Two moving rods slide through and slide on the side of the T-shaped block. One end of each of the two moving rods is fixedly connected to the same stabilizing arc block. A spring is provided between the stabilizing arc block and the T-shaped block. A horizontal plate is fixedly connected to the side of the stabilizing arc block. A hinge rod is hinged to the side of the horizontal plate. A loop block is hinged to the end of the hinge rod away from the horizontal plate. The inner wall of the loop block is slidably connected to the hollow frame. On the outer wall, when the threaded sleeve moves upward to the end just before stopping, the threaded sleeve will abut against the loop block, thereby moving the loop block upward along the outer wall of the hollow frame and compressing the second spring. The upward movement of the loop block will move the horizontal plate towards the hollow frame through the hinge rod. The movement of the horizontal plate will drive the stabilizing arc block towards the fixed ring. The movement of the stabilizing arc block will drive the moving rod to move along the inner wall of the T-shaped block, while stretching the first spring. At this time, the folded surface of the stabilizing arc block will fit against the outer wall of the fold of the exhaust duct.

[0010] According to the above technical solution, a limiting block is fixedly connected to the outer wall of the hollow frame. A spring is provided between the limiting block and the loop block. The loop block is located on the displacement trajectory of the threaded sleeve. The function of the spring between the limiting block and the loop block can provide a buffer effect for the loop block, preventing the loop block from being excessively displaced or impacted in the direction of the limiting block due to the movement of the threaded sleeve, thus protecting the entire mechanical structure from damage. At the same time, the setting of the limiting block restricts the maximum displacement range of the loop block, effectively preventing mechanical damage or failure caused by excessive displacement of the loop block, and increasing the safety of the equipment.

[0011] According to the above technical solution, the inner arc surface of the stabilizing arc block is folded. The inner and outer arc surfaces of the folded stabilizing arc block fit together with the fold of the outer wall of the fume duct, which helps to provide higher stability, making the contact between the stabilizing arc block and the duct tighter, and reducing loosening or displacement caused by vibration or external force.

[0012] According to the above technical solution, a cleaning device is provided at the bottom of the fixed ring. The cleaning device includes a short vertical rod, the top of which is fixedly connected to the bottom of the fixed ring, and a support ring is fixedly connected to the bottom of the short vertical rod. A cleaning ring is rotatably connected to the bottom of the support ring. Before passing through the fixed ring, the exhaust pipe passes through the brush part of the cleaning ring, so that the brush part of the cleaning ring cleans the impurities on the surface of the exhaust pipe.

[0013] According to the above technical solution, a short plate is fixedly connected to the side of the threaded sleeve, a spiral groove column is fixedly connected to the bottom of the short plate, a vertical block is fixedly connected to the bottom of the L-shaped block, a U-shaped long plate is fixedly connected to the bottom of the vertical block, and a rotating wheel is rotatably connected to the top of the U-shaped long plate. A rubber belt is directly rotatably connected to the cleaning ring. When the threaded sleeve moves upward, it will drive the short plate to move upward. The upward movement of the short plate will drive the spiral groove column to move upward. When the spiral groove column moves upward, it will cause the slider on the inner wall of the rotating wheel to move along the spiral groove of the spiral groove column, thereby causing the rotating wheel to rotate. The rotation of the rotating wheel will cause the cleaning ring to rotate through the rubber belt.

[0014] According to the above technical solution, the outer wall of the spiral groove column is provided with a spiral groove, and the inner wall of the rotating wheel is fixed with a slider for slidingly installed inside the spiral groove of the spiral groove column.

[0015] A method for hoisting the exhaust duct of a generator unit's oil tank includes the following steps: S1. Since the outer wall of one end of the exhaust pipe is not folded, first pass one end of the exhaust pipe through the fixing ring so that one end of the exhaust pipe is parallel to the arc block, and then start the electric push rod.

[0016] S2. The telescopic end of the electric push rod will push the arc block to move towards the exhaust duct, so that the arc block comes into contact with the outer wall of the exhaust duct. At this time, the air pump will cause the vacuum suction cup to adsorb the exhaust duct.

[0017] S3, thereby fixing the exhaust duct in place, and then the operator starts the motor. The motor's output shaft causes the threaded rod to rotate, and the rotation of the threaded rod causes the threaded sleeve to move upward.

[0018] S4. The upward movement of the threaded sleeve causes the electric push rod to move upward, which in turn causes the arc block to move upward. The upward movement of the arc block causes the exhaust duct to move upward, thus moving the exhaust duct to the corresponding position.

[0019] This invention provides a support and hanger for the exhaust duct of a generator set's oil tank, as well as a hoisting method. It offers the following advantages: (1) This invention utilizes the cooperation of a motor, threaded rod, threaded sleeve, electric push rod, arc block, air pump, and vacuum suction cup to move the arc block upward, which in turn moves the exhaust pipe upward, thus moving the exhaust pipe to the corresponding position. This achieves automatic traction of the exhaust pipe, avoiding the problem of the exhaust pipe falling from a height due to the operator's slip, which would damage the exhaust pipe. It also avoids improper operation caused by manual handling, which would affect the installation quality of the exhaust pipe. At the same time, through the cooperation of the touch plate, anti-pressure plate, and arc block, when the arc block moves towards the exhaust pipe, it will drive the touch plate to move. During the movement of the touch plate, it will be blocked by the anti-pressure plate, so that the arc block can make contact with the outer wall of the exhaust pipe, thus avoiding the problem of the exhaust pipe being damaged by excessive pressure from the arc block.

[0020] (2) The present invention uses the cooperation of T-shaped block, moving rod, stabilizing arc block, spring one, horizontal plate, hinge rod, U-shaped block, limiting block and spring two to make the movement of stabilizing arc block drive the moving rod to move along the inner wall of T-shaped block, and at the same time stretch spring one. At this time, the folding surface of stabilizing arc block will fit against the outer wall of the folding part of the exhaust pipe, thereby forming a stable support for the exhaust pipe, thus avoiding the problem of vibration of exhaust pipe when the oil fume airflow flows rapidly in exhaust pipe.

[0021] (3) By setting up a cleaning device, the brush part of the cleaning ring will clean the impurities on the surface of the exhaust pipe, thereby preventing the impurities from scratching the outer wall of the exhaust pipe when it passes through the inner wall of the fixed ring, thus damaging the protective layer (such as coating or paint) on the surface of the exhaust pipe and causing the exhaust pipe to be directly exposed to the air, thereby accelerating the oxidation and corrosion of the exhaust pipe material, especially in humid or chemical environments; at the same time, through the cooperation of the spiral groove column, vertical block, U-shaped long plate, rotating wheel, short vertical rod, support ring, cleaning ring, and rubber belt, the upward movement of the short plate will drive the spiral groove column to move upward. When the spiral groove column moves upward, the slider on the inner wall of the rotating wheel will move along the spiral groove of the spiral groove column, thereby causing the rotating wheel to rotate. The rotation of the rotating wheel will cause the cleaning ring to rotate through the rubber belt. The rotation of the cleaning ring can improve the cleaning effect of the impurities on the outer wall of the exhaust pipe. Attached Figure Description

[0024] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0025] Please see Figures 1-8One embodiment of the present invention is as follows: a support bracket for the exhaust duct of a generator oil tank, comprising an outer wall panel 1, a support frame 2 fixedly connected to the side of the outer wall panel 1, a fixing ring 3 fixedly connected to the inner wall of the support frame 2, four L-shaped blocks 4 fixedly connected to the side of the support frame 2, long blocks 5 fixedly connected to the side of each of the four L-shaped blocks 4, a hollow frame 6 fixedly connected between every two long blocks 5, a motor 7 fixedly connected to the bottom of the inner wall of the hollow frame 6, a threaded rod 10 fixedly connected to the output shaft of the motor 7, a threaded sleeve 11 threadedly connected to the outer wall of the threaded rod 10, an electric push rod 12 fixedly connected to the side of the threaded sleeve 11, and a telescopic end of the electric push rod 12 fixedly connected to the outer wall of the threaded rod 10. An arc block 13 is fixedly connected to the outer wall of the arc block 13, and a vacuum suction cup 15 is fixedly connected to the inner wall of the arc block 13. With the above structure, the electric push rod 12 moves upward, driving the arc block 13 to move upward. The upward movement of the arc block 13 will drive the exhaust duct to move upward, thereby moving the exhaust duct to the corresponding position. This realizes automatic traction of the exhaust duct, avoiding the problem of the exhaust duct falling from a height due to the worker's slip, which would damage the exhaust duct. At the same time, it can also avoid the situation where improper operation caused by manual operation affects the installation quality of the exhaust duct.

[0026] A touch plate 16 is fixedly connected to the bottom of the arc block 13, and an anti-pressure plate 17 is fixedly connected to the top of the fixing ring 3. The anti-pressure plate 17 is located on the displacement trajectory of the touch plate 16. The distance between the touch plate 16 and the inner arc surface of the arc block 13 is equal to the width of the anti-pressure plate 17. With the above structure, when the arc block 13 moves towards the exhaust duct, it will drive the touch plate 16 to move. During the movement of the touch plate 16, it will be blocked by the anti-pressure plate 17, so that the arc block 13 can contact the outer wall of the exhaust duct, thereby avoiding the problem of damage to the exhaust duct due to excessive compression by the arc block 13.

[0027] A vibration damping device 8 is provided on the side of the support frame 2. The vibration damping device 8 includes a T-shaped block 81. The side of the T-shaped block 81 is fixedly connected to the side of the support frame 2. Two sliding rods 82 pass through and slide on the side of the T-shaped block 81. One end of each of the two sliding rods 82 is fixedly connected to the same stabilizing arc block 83. A spring 84 is provided between the stabilizing arc block 83 and the T-shaped block 81. A horizontal plate 85 is fixedly connected to the side of the stabilizing arc block 83. A hinge rod 86 is hinged to the side of the horizontal plate 85. The hinge rod 86 is located away from the horizontal plate 85. A hinged loop block 87 is attached to the end. The inner wall of the loop block 87 is slidably connected to the outer wall of the hollow frame 6. With the above structure, the movement of the stabilizing arc block 83 will drive the moving rod 82 to move along the inner wall of the T-shaped block 81, while stretching the spring 84. At this time, the folded surface of the stabilizing arc block 83 will fit against the outer wall of the fold of the exhaust pipe, thus forming a stable support for the exhaust pipe and preventing the exhaust pipe from vibrating when the oil fume airflow flows rapidly in the exhaust pipe.

[0028] A limiting block 88 is fixedly connected to the outer wall of the hollow frame 6. A spring 89 is provided between the limiting block 88 and the loop block 87. The loop block 87 is located on the displacement trajectory of the threaded sleeve 11. Through the above structure, the spring 89 between the limiting block 88 and the loop block 87 can provide a buffer effect for the loop block 87, preventing the loop block 87 from being excessively displaced or impacted in the direction of the limiting block 88 due to the movement of the threaded sleeve 11, thus protecting the entire mechanical structure from damage. At the same time, the setting of the limiting block 88 limits the maximum displacement range of the loop block 87, effectively preventing mechanical damage or failure of the loop block 87 due to excessive displacement, and increasing the safety of the equipment.

[0029] The inner arc surface of the stabilizing arc block 83 is folded. Through the above structure, the inner and outer arc surfaces of the stabilizing arc block 83 fit together with the fold of the outer wall of the fume duct, which helps to provide higher stability and makes the contact between the stabilizing arc block 83 and the duct tighter, reducing loosening or displacement caused by vibration or external force.

[0030] In use, since the outer wall of one end of the exhaust duct is not folded, first pass one end of the exhaust duct through the fixing ring 3, making one end of the exhaust duct parallel to the arc block 13. Then, start the electric push rod 12. The telescopic end of the electric push rod 12 will push the arc block 13 towards the exhaust duct, so that the arc block 13 contacts the outer wall of the exhaust duct. At this time, the air pump 14 uses the vacuum suction cup 15 to adsorb the exhaust duct, thus fixing the exhaust duct. Then, the operator starts the motor 7. The output shaft of the motor 7 causes the threaded rod 10 to rotate. The rotation of the threaded rod 10 causes the threaded sleeve 11 to move upward. The upward movement of the threaded sleeve 11 drives the electric push rod 12 to move upward. The upward movement of the electric push rod 12 drives the arc block 13. Moving upwards, the arc block 13 moves the exhaust duct upwards, thus moving it to the corresponding position. This achieves automatic traction of the exhaust duct, preventing it from falling from a height due to operator slippage and potential damage. It also avoids improper manual operation that could affect the installation quality. As the arc block 13 moves towards the exhaust duct, it also moves the contact plate 16. During this movement, the contact plate 16 is blocked by the anti-pressure plate 17, ensuring that the arc block 13 makes proper contact with the outer wall of the exhaust duct. This prevents the exhaust duct from being damaged by excessive pressure from the arc block 13.

[0031] When the threaded sleeve 11 moves upward to a certain distance before stopping, the threaded sleeve 11 will abut against the loop block 87, thereby moving the loop block 87 upward along the outer wall of the hollow frame 6 and compressing the spring 89. The upward movement of the loop block 87 will cause the horizontal plate 85 to move towards the hollow frame 6 through the hinge rod 86. The movement of the horizontal plate 85 will drive the stabilizing arc block 83 to move towards the fixing ring 3. The movement of the stabilizing arc block 83 will drive the moving rod 82 to move along the inner wall of the T-shaped block 81, while stretching the spring 84. At this time, the folded surface of the stabilizing arc block 83 will fit against the outer wall of the fold of the exhaust pipe, thereby providing a stable support for the exhaust pipe and preventing the exhaust pipe from vibrating when the oil fume airflow flows rapidly inside the exhaust pipe.

[0032] Please see Figures 1-8Based on the above embodiments, in another embodiment of the present invention, a cleaning device 9 is provided at the bottom of the fixing ring 3. The cleaning device 9 includes a short vertical rod 96, the top of which is fixedly connected to the bottom of the fixing ring 3, and a support ring 97 is fixedly connected to the bottom of the short vertical rod 96. A cleaning ring 98 is rotatably connected to the bottom of the support ring 97. With the above structure, the brush part of the cleaning ring 98 will clean the impurities on the surface of the exhaust pipe, thereby preventing impurities from scratching the outer wall of the exhaust pipe when it passes through the inner wall of the fixing ring 3, thus damaging the protective layer such as coating or paint on the surface of the exhaust pipe, causing the exhaust pipe to be directly exposed to the air, thereby accelerating the oxidation and corrosion of the exhaust pipe material, especially in humid or chemical environments.

[0033] A short plate 91 is fixedly connected to the side of the threaded sleeve 11. A spiral groove column 92 is fixedly connected to the bottom of the short plate 91. A vertical block 93 is fixedly connected to the bottom of the L-shaped block 4. A U-shaped long plate 94 is fixedly connected to the bottom of the vertical block 93. A rotating wheel 95 is rotatably connected to the top of the U-shaped long plate 94. A rubber belt 99 is directly rotatably connected to the cleaning ring 98. A spiral groove is opened on the outer wall of the spiral groove column 92. A slider is fixed on the inner wall of the rotating wheel 95 for sliding inside the spiral groove of the spiral groove column 92. The surface of the slider is set to be smooth. With the above structure, when the spiral groove column 92 moves upward, the slider on the inner wall of the rotating wheel 95 will move along the spiral groove of the spiral groove column 92, thereby causing the rotating wheel 95 to rotate. The rotation of the rotating wheel 95 will cause the cleaning ring 98 to rotate through the rubber belt 99. The rotation of the cleaning ring 98 can improve the cleaning effect of the impurities on the outer wall of the exhaust pipe.

[0034] During use, the exhaust duct passes through the brush portion of the cleaning ring 98 before passing through the fixed ring 3. This brush portion cleans impurities from the surface of the exhaust duct, preventing scratches on the outer wall of the exhaust duct when it passes through the inner wall of the fixed ring 3. This prevents damage to the protective layers such as coatings or paints, which would expose the exhaust duct directly to the air and accelerate oxidation and corrosion of the exhaust duct material, especially in humid or chemically exposed environments. When the threaded sleeve 11 moves upward, it drives the short plate 91 upward, which in turn drives the spiral groove column 92 upward. The upward movement of the spiral groove column 92 causes the slider on the inner wall of the rotating wheel 95 to move along the spiral groove of the spiral groove column 92, causing the rotating wheel 95 to rotate. The rotation of the rotating wheel 95 causes the cleaning ring 98 to rotate via the rubber belt 99. The rotation of the cleaning ring 98 improves the cleaning effect on the outer wall of the exhaust duct.

[0035] The above are merely preferred embodiments of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.

The telescopic end of the electric push rod (12) will push the arc block (13) to move towards the direction of the exhaust pipe, so that the arc block (13) comes into contact with the outer wall of the exhaust pipe. At this time, the air pump (14) will cause the vacuum suction cup (15) to adsorb the exhaust pipe. S3, thereby fixing the exhaust pipe, and then the staff starts the motor (7), the output shaft of the motor (7) causes the threaded rod (10) to rotate, and the rotation of the threaded rod (10) causes the threaded sleeve (11) to move upward; S4. The upward movement of the threaded sleeve (11) causes the electric push rod (12) to move upward. The upward movement of the electric push rod (12) causes the arc block (13) to move upward. The upward movement of the arc block (13) will cause the exhaust pipe to move upward, thereby moving the exhaust pipe to the corresponding position.
