Description

Technical Field

[0001] This utility model relates to the technical field of metal surface treatment equipment, specifically to a high-temperature pyrolysis paint stripping hanger that is easy to replace. Background Technology

[0002] In industrial fields such as coating and electroplating, workpieces need to be placed on spraying racks for coating or electroplating. Sometimes, the coating on the workpiece needs to be removed by high-temperature pyrolysis paint removal process. In order to make the workpiece heated more evenly during the high-temperature pyrolysis paint removal process, the spraying rack needs to be placed on the high-temperature pyrolysis paint removal rack. The existing high-temperature pyrolysis paint stripping rack is an integral welded rack, which is connected to external equipment through bolts and bolt holes on the upper side of the rack. The workpiece to be stripped is then placed on the rack to facilitate subsequent paint stripping operations. Existing high-temperature pyrolysis paint stripping hangers use multiple sets of bolts to connect to external equipment. Disassembling these hangers requires repeated bolt removal and reassembly, which is cumbersome and affects the efficiency of disassembly and reassembly. Furthermore, once the high-temperature pyrolysis paint stripping hanger is designed, its structure is fixed and cannot be adapted to the suspension requirements of workpieces of different heights, resulting in poor versatility. Therefore, we propose a high-temperature pyrolysis paint stripping hanger that is easy to replace. Utility Model Content

[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. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] Please see Figure 1-5 This embodiment provides a technical solution: a high-temperature pyrolysis paint stripping hanger that is easy to replace, including a support frame 1, a hook mounting base 2 fixedly connected to the upper side of the rear surface of the support frame 1, an mounting rod rotatably connected to the upper side of the hook mounting base 2, a hook 3 fixedly connected to the outer surface of the mounting rod, and a fixing mechanism 7. Fixing mechanism 7 includes a rotating rod 71, a lever 72, an arc-shaped slider 73, a locking block 74, a sliding column 75, and a spring 76. The rotating rod 71 is rotatably connected to the upper inner side of the hook mounting base 2. The left end of the rotating rod 71 is fixedly connected to the right end of the mounting rod. The lever 72 is fixedly connected to the outer surface of the rotating rod 71. The arc-shaped slider 73 is slidably connected to the right inner side of the hook mounting base 2. The right surface of the arc-shaped slider 73 is fixedly connected to evenly distributed locking blocks 74. The locking blocks 74 cooperate with the lever 72 for installation. The inside of the hook mounting base 2... A sliding column 75 is slidably connected on the left side. The right end of the sliding column 75 is fixedly connected to the left surface of the arc-shaped slider 73. A spring 76 is fixedly connected between the left surface of the arc-shaped slider 73 and the inner wall of the hook mounting base 2. The spring 76 is sleeved on the outer surface of the sliding column 75. (A protective cover is fixedly connected to the left surface of the hook mounting base 2 by bolts. The protective cover can be removed to replace the spring 76, preventing the spring 76 from losing its elasticity after long-term use and becoming unusable.) The fixing mechanism 7 also includes a locking bolt. 77, the locking bolt 77 is threaded onto the lower side of the hook mounting base 2. Moving the lever 72 causes the rotating rod 71 to rotate, which in turn rotates the mounting rod, causing the hook 3 to rotate around the central axis of the mounting rod, thus opening the hook 3 and placing it outside the external connecting hook or external connecting rod. Moving the lever 72 at this time causes the rotating rod 71 to reverse, which in turn rotates the mounting rod, causing the hook 3 to move closer to the hook mounting base 2. This causes the hook 3 and the hook mounting base 2 to clamp the external connecting hook or external connecting rod. Simultaneously, the lever 72 squeezes... Press the inclined surface of the locking block 74 to move the arc-shaped sliding block 73 to the left until the hook 3 and the hook mounting seat 2 fully clamp the external connecting hook or external connecting rod. At this time, the spring 76 relaxes and pushes the arc-shaped sliding block 73 and the locking block 74 to the right, so that the lever 72 is in contact with the plane of the locking block 74, thereby locking the lever 72. Then rotate the locking bolt 77 so that the upper end of the locking bolt 77 is in close contact with the outer surface of the sliding column 75, thereby further locking the sliding column 75 and increasing the locking strength of the lever 72. A groove 8 is provided on the right side of the interior of the support frame 1. A suspension bracket 4 is slidably connected to the upper interior of the support frame 1. A slider 9 is fixedly connected to the right side of the suspension bracket 4. The slider 9 is slidably connected within the groove 8. A locking bolt 10 is threadedly connected to the inside of the slider 9. A suspension bracket 5 is slidably connected to the lower interior of the support frame 1. A slider 2 is fixedly connected to the right side of the suspension bracket 5. The slider 2 is slidably connected within the groove 8. A locking bolt 11 is threadedly connected to the inside of the slider 2. When it is necessary to adjust the position of the suspension bracket 4 and the suspension bracket 5... During adjustment, locking bolts 210 and 311 can be rotated respectively to make the right ends of locking bolts 210 and 311 no longer tightly attached to the inner wall of the slide groove 8, thereby unlocking slider 19 and slider 2, thereby unlocking suspension bracket 14 and suspension bracket 25, and then the positions of suspension bracket 14 and suspension bracket 25 can be adjusted. After adjustment, locking bolts 210 and 311 are reversed to make the right ends of locking bolts 210 and 311 tightly attached to the inner wall of the slide groove 8, thereby locking slider 19 and slider 2. The right side of the inner side of the support frame 1 has evenly distributed mounting slots 12. Each mounting slot 12 has a slidably connected stop block 13. A protective shell 6 is fixedly connected to the right surface of the support frame 1. A movable rod 14 is slidably connected inside the protective shell 6. The right surface of each stop block 13 is fixedly connected to the left surface of the movable rod 14. Slide rods 15 are fixedly connected to both the upper and lower ends of the movable rod 14. A second spring 16 is fixedly connected between the upper surface of the movable rod 14 and the inner wall of the protective shell 6. The second spring 16 is sleeved on the outer surface of the upper slide rod 15. (A top cover is fixedly connected to the upper surface of the protective shell 6 by bolts, allowing the top cover to be...) The cover is removed to replace spring 16, preventing it from becoming unusable due to reduced elasticity after prolonged use. Both spring 76 and spring 16 are high-temperature resistant springs, and the protective shell 6, load-bearing frame 1, and hook mounting base 2 are made of ceramic fiber, providing a certain degree of heat insulation. This heat insulation treatment extends the service life of springs 76 and 16. A pull ring 17 is fixedly connected to the upper end of the upper slide rod 15, and a limit hole is opened inside the lower slide rod 15, into which a limit pin 1 is inserted. 8. When it is necessary to remove or replace the first suspension bracket 4 and the second suspension bracket 5, pull the limiting pin 18 out of the limiting hole, then pull the pull ring 17 upward to move the movable rod 14 upward. The second spring 16 retracts, causing the stop block 13 to move upward and enter the interior of the longitudinally adjacent mounting groove 12. At this time, multiple clearance grooves appear on the rear side of the slide groove 8. After unlocking the first suspension bracket 4 or the second suspension bracket 5, make the first slider 9 or the second slider and the clearance groove are on the same horizontal plane. Then push the first suspension bracket 4 or the second suspension bracket 5 backward to make the first slider 9 or the second slider move out of the slide groove 8. The internal movement allows for the removal of either the first or second suspension bracket 4, enabling the replacement of either the first or second suspension bracket 5. After replacement, the first or second suspension bracket 4 is pushed forward, causing either the first or second slider to pass through the clearance groove and enter the interior of the slide groove 8. At this point, the pull ring 17 is released, the second spring 16 relaxes, and the movable rod 14 is pushed downward, causing the stop block 13 to reset. The limit pin 18 is then reinserted into the limit hole, and the first or second suspension bracket 4 is locked, thus enabling the replacement and installation of either the first or second suspension bracket 5.

[0017] The working principle of the high-temperature pyrolysis paint stripping hanger provided by this utility model is as follows: When using the high-temperature pyrolysis paint stripping hanger, move the lever 72 to rotate the rotating rod 71, which in turn rotates the mounting rod, causing the hook 3 to rotate around the central axis of the mounting rod, thereby opening the hook 3 and placing it outside the external connecting hook or external connecting rod. At this time, move the lever 72 to reverse the rotating rod 71, which in turn reverses the mounting rod, causing the hook 3 to move closer to the hook mounting seat 2, thereby clamping the hook 3 and the hook mounting seat 2 together with the external connecting hook or external connecting rod. At the same time, the lever 72 presses the inclined surface of the locking block 74, causing the locking block 74 to move the arc-shaped sliding block 73 to the left until the hook 3 and the hook mounting seat 2 are completely clamped together with the external connecting hook. When the hook or external connecting rod is engaged, the spring 76 relaxes, pushing the arc-shaped sliding block 73 and the locking block 74 to the right, causing the lever 72 to engage with the plane of the locking block 74, thereby locking the lever 72. Then, the locking bolt 77 is rotated so that its upper end is pressed against the outer surface of the sliding column 75, thereby further locking the sliding column 75 and increasing the locking strength of the lever 72. The workpiece is suspended by the hook of the suspension bracket 4 or placed on the upper end of the suspension bracket 5. When the position of the suspension bracket 4 and the suspension bracket 5 needs to be adjusted, the locking bolts 10 and 11 can be rotated respectively so that the right ends of the locking bolts 10 and 11 are no longer pressed against the inner wall of the slide groove 8, thereby locking the slider 9. Unlock slider 2 to unlock suspension bracket 1 4 and suspension bracket 2 5, allowing adjustment of their positions. After adjustment, reverse locking bolts 2 10 and 3 11 so their right ends are pressed against the inner wall of slide groove 8, locking slider 1 9 and slider 2. When suspension bracket 1 4 and suspension bracket 2 5 need to be removed or replaced, pull limit pin 18 out of the limit hole, then pull ring 17 upward to move movable rod 14 upward, spring 2 16 retracts, causing stop block 13 to move upward and enter the longitudinally adjacent mounting groove 12. At this time, multiple clearance grooves appear on the rear side of slide groove 8, allowing the suspension bracket to be placed... After unlocking the first bracket 4 or the second hanging bracket 5, align the first slider 9 or the second slider with the clearance groove on the same horizontal plane. Then, push the first hanging bracket 4 or the second hanging bracket 5 backward, causing the first slider 9 or the second slider to leave the inside of the slide groove 8, thereby disassembling the first hanging bracket 4 or the second hanging bracket 5. Then, replace the first hanging bracket 4 or the second hanging bracket 5. After replacement, push the first hanging bracket 4 or the second hanging bracket 5 forward, causing the first slider 9 or the second slider to pass through the clearance groove and enter the inside of the slide groove 8. At this time, release the pull ring 17, the second spring 16 relaxes, pushing the movable rod 14 downward to reset the stop block 13. Reinsert the limit pin 18 into the limit hole, and then lock the first hanging bracket 4 or the second hanging bracket 5.This allows for the replacement and installation of either the first hanging rack 4 or the second hanging rack 5. Workpieces are suspended via the hooks of the first hanging rack 4, or placed on the upper end of the second hanging rack 5.
