Description

Technical Field

[0001] This utility model belongs to the field of industrial door technology, and specifically relates to a track-integrated industrial lifting door. Background Technology

[0002] The track-mounted industrial overhead door consists of a series of door panels that rise along the track. Industrial overhead doors offer a grand appearance and a comfortable user experience. Larger industrial products, with their stable and spectacular operation, provide a strong visual impact. The door's balance is ensured by a torsion spring system or a counterweight system. Different track systems and lifting methods allow the industrial overhead door panels to adapt to different buildings. Available in a variety of colors, its ingenious design makes it suitable for almost any building exterior door.

[0003] However, in traditional industrial overhead doors with built-in tracks, the accumulation of dust and metal debris in the tracks increases the coefficient of friction, leading to increased resistance during door operation. This not only accelerates track wear and shortens service life but may also cause motor overload failures. In addition, the door may directly collide with the ground when it falls, and long-term impact can easily cause structural damage such as door frame deformation and hinge loosening. The direct friction of metal parts not only produces harsh noise but may also cause sparks that pose a safety hazard.

[0004] To address the problems mentioned in the background above, a track-integrated industrial overhead door is proposed. Utility Model Content

[0005] The purpose of this utility model is to provide an industrial lifting door with built-in track, which has the advantages of dust cleaning and buffer protection.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a track-integrated industrial lifting door includes a door panel, sleeves are bolted to both sides of the front of the door panel, pulleys are rotatably fitted inside the sleeves, tracks are provided on both sides of the door panel, a slot is opened at the rear end of the inner side of the track, a wheel rail is opened inside the slot, and the inner wall of the wheel rail is slidably connected to the surface of the pulley, an elastic sheet is welded to the top of the sleeve, a connecting rod is bolted to the top of the elastic sheet, and the surface of the connecting rod penetrates the interior of the slot, a scraper is bolted to the left side of the connecting rod, and the surface of the scraper is slidably connected to the inner wall of the wheel rail, a buffer mechanism is provided at the bottom of the door panel, and a drive mechanism is provided at the top of the track.

[0007] The above technical solution works as follows: When the door panel is raised or lowered, the door panel drives the sleeves on both sides to move synchronously. The sleeves drive the pulleys to move, and the wheel rail provides directional constraints for the pulleys, ensuring that the pulleys move along the track direction, thereby limiting the movement trajectory of the door panel. When the pulleys slide on the wheel rail, if there are slight unevennesses on the inner wall of the wheel rail, the elastic plate will adaptively adjust the position of the connecting rod through its own elastic deformation, thereby providing continuous and stable pressure to the scraper, ensuring that the scraper is always tightly attached to the inner wall of the wheel rail. Therefore, when the door panel raises or lowers the sleeves and pulleys, the connecting rod moves with the sleeves. Synchronous movement drives the scraper to slide along the inner wall of the wheel rail. Because the elastic sheet always provides contact pressure for the scraper, the scraper can directly scrape off dust, debris and other debris attached to the inner wall of the wheel rail during the sliding process. It has a significant cleaning and maintenance function. During the operation of the door, it continuously physically scrapes the inner wall of the track, which can effectively remove common pollutants such as dust and debris. This self-cleaning mechanism not only reduces the risk of track jamming and extends the service life of the slide rail, but also reduces the increase in motor load caused by the accumulation of debris, while avoiding the safety hazards of manual cleaning.

[0008] The present invention is further configured such that the buffer mechanism includes a protective plate, the protective plate is located at the bottom of the bottom panel, a spring is bolted to the bottom of the protective plate, and a damper is sleeved inside the spring.

[0009] The above technical solution employs a buffer mechanism. When the door panel descends, the bottom of the bottom panel contacts the top of the protective plate. The protective plate absorbs the downward pressure of the door panel and moves downward. The protective plate causes the spring to contract, further absorbing the pressure. Subsequently, the spring rebounds, causing the protective plate to return to its original position. The damper prevents the spring from continuously rebounding and causing damage to the bottom of the door panel, thus achieving buffer protection for the door's descent. When the door approaches the ground, it absorbs the impact kinetic energy, avoiding structural deformation caused by rigid collisions between the door and the ground. It also eliminates noise and sparks generated by metal friction. Especially under frequent opening and closing conditions, it significantly improves the door's impact resistance and operational stability, while reducing maintenance needs caused by mechanical collisions.

[0010] The present invention is further configured such that the driving mechanism includes a back plate located at the top of the track, a motor is bolted to the right side of the back plate, a rotating rod is fixedly sleeved to the left side of the motor, torsion springs are fixedly sleeved on both sides of the rotating rod surface near the middle, and drums are fixedly sleeved on both sides of the rotating rod surface away from the middle, a steel cable is roped to the surface of the drum, and the end of the steel cable away from the drum is fixedly connected to both sides located at the bottom of the front of the bottom panel, and an opening is provided at the front end of the inner side of the track, and the surface of the steel cable penetrates the interior of the opening.

[0011] The above technical solution is adopted as follows: By setting up a drive mechanism, when the motor starts, it drives the rotating rod to rotate. The rotation of the rotating rod causes the two drums on both sides to wind the steel cable. The steel cable passes through the track opening and pulls the bottom door panel up. At the same time, the torsion spring in the middle of the rotating rod is twisted and stores energy. When the motor runs in reverse or stops, the torsion spring releases potential energy and drives the rotating rod to rotate in the opposite direction. The drum releases the steel cable, and the door panel descends under its own weight and the action of the torsion spring. The steel cable moves with the door panel and always passes through the track opening.

[0012] The present invention is further configured such that a slider is welded to the front and back of the connecting rod, and a sliding groove is provided at the front and rear ends of the slot, and the interior of the sliding groove is slidably connected to the surface of the slider.

[0013] By adopting the above technical solution, the movement of the connecting rod can be limited by setting a slider and a groove, preventing the connecting rod from tilting or shifting when the scraper is working.

[0014] The present invention is further configured such that the bottom of the track is provided with a ground, the top of the ground is provided with a groove, and the bottom of the groove is bolted to the bottom of the spring.

[0015] The above technical solution involves setting a groove in the ground directly below the door panel.

[0016] The present invention is further configured such that two sliders are bolted to both sides of the protective plate, and two sliding grooves are provided on both sides inside the groove, and the interior of the sliding grooves is slidably connected to the surface of the sliders.

[0017] The above technical solution is adopted: by setting slider two and slide groove two, the movement of the protective plate can be limited.

[0018] The present invention is further configured such that the top of the scraper is a slope.

[0019] The above technical solution involves setting the surface as a ramp, which allows dust and debris to be easily scraped off during scraping operations and then slid down the ramp to the outside for easy cleaning.

[0020] The present invention is further configured such that the back of the track and the back plate are bolted to the wall.

[0021] The above technical solution involves installing a wall surface, with the track and back panel connected to the wall via self-tapping expansion bolts.

[0022] In summary, this utility model has the following beneficial effects:

[0023] 1. This utility model has a significant cleaning and maintenance function. During the operation of the door, it continuously physically scrapes the inner wall of the track, which can effectively remove common pollutants such as dust and debris. This self-cleaning mechanism not only reduces the risk of track jamming and extends the service life of the slide rail, but also reduces the increase in motor load caused by the accumulation of debris, while avoiding the safety hazards of manual cleaning.

[0024] 2. This utility model provides buffer protection for the door when it falls. When the door approaches the ground, it absorbs the impact kinetic energy, which can prevent structural deformation caused by rigid collision between the door and the ground. It also eliminates noise and sparks generated by metal friction. Especially under the condition of frequent opening and closing, it significantly improves the impact resistance and operational stability of the door, while reducing the maintenance needs caused by mechanical collision.

[0032] The present invention will be further described in detail below with reference to the accompanying drawings.

[0033] Example 1:

[0034] refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 A track-embedded industrial overhead door includes a door panel 1, which is composed of polyurethane, a substrate protective layer, a steel plate, and a PVDF surface coating. The polyurethane foam material used is entirely 141B, replacing the chlorofluorocarbon-based foaming agent, making it 100% CFC-free and transforming the polyurethane foaming process into an environmentally friendly production process that meets environmental standards. Sleeve boxes 2 are bolted to both sides of the front of the door panel 1, using M8 stainless steel bolts with a tightening torque of 25-30 N·m and a weld strength ≥300 MPa. Inside the sleeve boxes 2, rotatably fitted pulleys 3 are made of high-strength nylon. The door panel 1 has tracks 4 on both sides, made of galvanized steel. The rear end of the inner side of the track 4 has a slot 5, and the inner side of the slot 5 has a wheel rail 6. The inner wall of the wheel rail 6 is slidably connected to the surface of the pulley 3. The top of the sleeve box 2 is welded with an elastic sheet 7, which is argon arc welded to the sleeve box 2. The elastic sheet 7 is made of 65Mn spring steel, 1.5-2mm thick, with a free-state curvature of R50-R80mm and an elastic deformation range ≤10mm. A connecting rod 8 is bolted to the top of the elastic sheet 7, and the surface of the connecting rod 8 penetrates the interior of the slot 5. A scraper 9 is bolted to the left side of the connecting rod 8. The scraper 9 is slidably connected to the inner wall of the wheel rail 6. The scraper 9 is made of nitrile rubber with a hardness of 60-70 Shore A. Its width is 30-50mm to match the inner wall of the wheel rail, and its length is 50-80mm. A buffer mechanism is provided at the bottom of the door panel 1, and a drive mechanism is provided at the top of the track 4. When the door panel 1 is raised or lowered, the door panel 1 drives the sleeves 2 on both sides to move synchronously. The sleeves 2 drive the pulleys 3 to move. The wheel rail 6 provides directional constraints for the pulleys 3, ensuring that the pulleys 3 move along the direction of the track 4, thereby limiting the movement trajectory of the door panel 1. When the pulleys 3 slide on the wheel rail 6, if there are small... If the surface is uneven, the elastic sheet 7 will adaptively adjust the position of the connecting rod 8 through its own elastic deformation, thereby providing continuous and stable pressure to the scraper 9, ensuring that the scraper 9 is always in close contact with the inner wall of the wheel track 6. Therefore, when the door panel 1 drives the sleeve 2 and pulley 3 to rise and fall, the connecting rod 8 moves synchronously with the sleeve 2, thereby driving the scraper 9 to slide along the inner wall of the wheel track 6. Since the elastic sheet 7 always provides contact pressure to the scraper 9, the scraper 9 can directly scrape off the dust, debris and other debris attached to the inner wall of the wheel track 6 during the sliding process, which has a significant cleaning and maintenance function, and continuously physically scrapes the inner wall of the track 4 during the operation of the door.

[0035] refer to Figure 1 , Figure 2The drive mechanism includes a back plate 13, which is located on top of the track 4. A motor 14 is bolted to the right side of the back plate 13, with a power of 0.75-1.5kW, a speed of 1400-2800r / min, and an output torque of 10-20N·m. A rotating rod 15 is fixedly sleeved to the left side of the motor 14. Torsion springs 16 are fixedly sleeved on both sides of the rotating rod 15 near the center. Drums 17 are fixedly sleeved on both sides of the rotating rod 15 away from the center. A steel cable 18 is roped to the surface of the drum 17. The cable is made of galvanized steel wire rope with a diameter of 6-8mm, a breaking strength ≥50kN, and a safety factor ≥5. The end of the steel cable 18 away from the drum 17 is connected to the bottom door plate 1. The bottom two sides are fixedly connected. An opening 19 is opened at the front end of the inner side of the track 4, and the surface of the steel cable 18 passes through the inside of the opening 19. By setting a drive mechanism, when the motor 14 starts, it drives the rotating rod 15 to rotate. The rotation of the rotating rod 15 causes the two drums 17 to wind the steel cable 18. The steel cable 18 passes through the opening 19 of the track 4 and pulls the bottom door panel 1 to rise. At the same time, the torsion spring 16 in the middle of the rotating rod 15 is twisted and stores energy. When the motor 14 runs in reverse or stops, the torsion spring 16 releases potential energy and drives the rotating rod 15 to rotate in the opposite direction. The drum 17 releases the steel cable 18, and the door panel 1 descends under its own weight and the action of the torsion spring 16. The steel cable 18 moves with the door panel 1 and always passes through the opening 19 of the track 4.

[0036] refer to Figure 2 , Figure 3 , Figure 4 , Figure 5 The front and back of the connecting rod 8 are welded with slider 20. The front and rear ends of the slot 5 are provided with sliding groove 21, and the inside of the sliding groove 21 is slidably connected to the surface of slider 20. By setting slider 20 and sliding groove 21, the movement of the connecting rod 8 can be limited to prevent the connecting rod 8 from tilting or shifting when the scraper 9 is working.

[0037] refer to Figure 2 , Figure 3 , Figure 4 The top of the scraper 9 is set as a slope. By setting it as a slope, dust and debris can be easily scraped off when the scraper 9 is working. The debris slides to the outside along the slope for easy cleaning. The slope angle is 15°-20° and the slope surface is polished with a roughness Ra≤1.6μm.

[0038] refer to Figure 1 , Figure 2 The back of the track 4 and the back plate 13 are bolted to the wall. By setting the wall, the track 4 and the back plate 13 are connected to the wall by self-tapping expansion bolts.

[0039] Example 2:

[0040] refer to Figure 1 , Figure 2 , Figure 3 , Figure 6 A track-integrated industrial lifting door includes a buffer mechanism comprising a protective plate 10. The protective plate 10 is made of 3-5mm thick galvanized steel sheet, with a rust-removing treatment followed by spraying with anti-rust paint, the film thickness being 60-80μm. This meets both impact strength requirements and corrosion resistance requirements in industrial environments. The protective plate 10 is located at the bottom of the bottom door panel 1. A spring 11 is bolted to the bottom of the protective plate 10. The spring 11 is made of 60Si2Mn material, with a wire diameter of 8-12mm, a free length of 100-150mm, and a spring force of 500-800N when compressed by 30-50mm. A damper 12 is fitted inside the spring 11. The damper is a hydraulic damper with a damping coefficient of 50-100 N·s / m. The maximum stroke matches the spring compression of 30-50 mm. When the door panel 1 descends, the bottom of the bottom door panel 1 contacts the top of the protective plate 10. The protective plate 10 absorbs the downward pressure of the door panel 1 and moves downward. The protective plate 10 drives the spring 11 to contract, further absorbing the pressure. Then the spring 11 rebounds and drives the protective plate 10 back to its original position. The damper 12 prevents the spring 11 from continuously rebounding and causing damage to the bottom of the door panel 1, thus achieving buffer protection when the door falls.

[0041] refer to Figure 2 , Figure 3 , Figure 6 The bottom of the track 4 is provided with a ground, and the top of the ground is provided with a groove 24. The bottom of the groove 24 is bolted to the bottom of the spring 11. The groove 24 is provided and is located on the ground directly below the door panel 1.

[0042] refer to Figure 2 , Figure 3 , Figure 6 The protective plate 10 has two sliders 22 bolted to both sides. The groove 24 has two sliding grooves 23 on both sides, and the interior of the sliding grooves 23 is slidably connected to the surface of the sliders 22.

[0043] Brief description of the usage process: When the door panel 1 is raised or lowered, the door panel 1 drives the sleeve boxes 2 on both sides to move synchronously. The sleeve boxes 2 drive the pulleys 3 to move. The wheel rail 6 provides directional constraint for the pulleys 3, ensuring that the pulleys 3 move along the direction of the track 4, thereby limiting the movement trajectory of the door panel 1. When the pulleys 3 slide on the wheel rail 6, if there are slight unevennesses on the inner wall of the wheel rail 6, the elastic plate 7 will adaptively adjust the position of the connecting rod 8 through its own elastic deformation, thereby providing continuous and stable pressure to the scraper 9, ensuring that the scraper 9 is always tightly attached to the inner wall of the wheel rail 6. Therefore, when the door panel 1 drives the sleeve boxes 2 and pulleys 3 to rise or fall, the connecting rod 8 moves synchronously with the sleeve boxes 2, thereby driving the scraper 9 along the inner wall of the wheel rail 6. During sliding, because the elastic sheet 7 always provides contact pressure for the scraper 9, the scraper 9 can directly scrape off dust, debris and other impurities attached to the inner wall of the wheel track 6 during the sliding process, which has a significant cleaning and maintenance function. During the operation of the door, it continuously physically scrapes the inner wall of the track 4. When the door panel 1 descends, the bottom of the bottom door panel 1 contacts the top of the protective plate 10. The protective plate 10 absorbs the downward pressure of the door panel 1 and moves downward. The protective plate 10 drives the spring 11 to contract, further absorbing the pressure. Then the spring 11 rebounds and drives the protective plate 10 back to its position. The damper 12 prevents the spring 11 from continuously rebounding and causing damage to the bottom of the door panel 1, thus realizing the buffer protection of the door falling.

[0044] It should be noted that parts have a lifespan and can be replaced during regular maintenance when they no longer meet performance requirements. Deterioration in performance due to prolonged use of parts is not a design defect of this application.
