Description

Technical Field

[0001] The utility model relates to the field of hangar doors, in particular to a heavy-duty hangar door with a guide mechanism. Background Art

[0002] Hangar doors are large doors used in large industrial or aviation facilities to cover and protect aircraft, vehicles, or other large mechanical equipment. Hangar doors are usually designed according to the door opening size and usage requirements. They may be single-leaf doors or multiple continuous doors with movable columns. The size of the door can be customized according to actual needs without rigid restrictions to accommodate the passage of aircraft of different sizes.

[0003] In the existing technology, most hangar doors adopt a track design, that is, the hangar doors move within a fixed track. Since the volume of hangar doors is much larger than other types of doors, long-term friction with the track will cause the hangar doors to swing or even shift, thereby affecting the stability of the hangar doors. Utility Model Content

[0004] The technical problem to be solved by the utility model is to provide a heavy-duty hangar door with a guide mechanism.

[0005] In order to solve the above technical problems, the technical solution of the utility model is: a heavy-duty hangar door with a guide mechanism, comprising a lower guide rail, the upper edge of the lower guide rail is fixedly connected to a door frame, a guide groove is provided inside the lower guide rail, a placement groove is provided on one side of the guide groove, a motor is provided inside the placement groove, a screw rod is provided at the output end of the motor, a support plate is fixedly connected to the front side of the lower guide rail, a guide plate is slidably connected to the inside of the guide groove, a threaded hole is provided inside the guide plate, the upper end of the guide plate is fixedly connected to a hangar door body, and a rubber pad is provided on the right side of the hangar door body.

[0006] Preferably, the front edge of the guide plate is fixedly connected to a fixing seat, a slot is provided in the middle of the front side of the fixing seat, and rotation slots are provided on the left and right sides of the fixing seat. A short rod is provided inside the rotation slot, and a fixing rod is sleeved on the outside of the short rod. The front side of the fixing rod is fixedly connected to a bolt, and a pressure ring is sleeved on the outside of the bolt, and a nut is fixedly connected to the front side of the pressure ring.

[0007] Preferably, a mounting block is slidably connected to the interior of the card slot, a mounting plate is fixedly connected to one side of the mounting block, and a guide wheel is provided on the front side of the mounting plate.

[0008] Preferably, the internal thread of the guide plate is adapted to the external thread of the screw rod.

[0009] Preferably, the guide plate slides in the guide groove in cooperation with the screw rod through its internal threaded hole.

[0010] Preferably, the fixing rod is movably connected to the fixing seat via a short rod.

[0011] By adopting the above technical solution, by starting the motor, the motor drives the screw to rotate, and the guide plate slides in the lower guide rail using its internal threaded hole, thereby realizing the movement of the warehouse door body. During the sliding process of the guide plate, the guide wheels on both sides of the warehouse door body roll on the support plate, which increases the stability of the warehouse door body when opening and closing. At the same time, the rubber pad plays a buffering role, reducing the impact force of the warehouse door body and reducing the noise caused by impact. The guide wheel can be moved by the wire plate and the internal threaded hole in conjunction with the motor and the screw, ensuring that the door body runs smoothly on the track, reducing friction, and making the opening and closing of the warehouse door body smoother. This design not only improves the operating efficiency and stability of the warehouse door body, but also reduces noise and maintenance costs.

[0012] By adopting the above technical solution, by rotating the nut, under the action of its internal thread and the external thread of the bolt, the retaining ring moves away from one side of the mounting plate, and the fixing rod rotates out from the inside of the limit groove, releasing the limit on the mounting plate, and completing the disassembly of the guide wheel. Similarly, during installation, the mounting block is slid into the retaining groove and the fixing rod and nut are rotated. The fixing rod rotates outside the short rod and enters the rotating groove. The nut fixes the pressure ring to the mounting plate, thereby realizing the installation of the guide wheel. The guide wheel can be loaded and unloaded by the mounting block, mounting plate, fixing rod, bolt, nut, and pressure ring, and can be replaced when it is damaged, which also reduces the difficulty of maintaining the guide wheel.

[0022] Specifically, the motor 4 is started, and the motor 4 drives the screw rod 5 to rotate. The guide plate 8 slides in the lower guide rail 1 using its internal threaded hole 9, thereby realizing the movement of the warehouse door body 10. During the sliding process of the guide plate 8, the guide wheels 22 on both sides of the warehouse door body 10 roll on the support plate 7, which increases the stability of the warehouse door body 10 when opening and closing. At the same time, the rubber pad 11 plays a buffering role, reducing the impact force of the warehouse door body 10 and reducing the noise caused by the impact. The guide wheel 22 can be moved by the wire plate and the internal threaded hole 9 in conjunction with the motor 4 and the screw rod 5, ensuring that the door body runs smoothly on the track, reducing friction, and making the opening and closing of the warehouse door body 10 smoother. This design not only improves the operating efficiency and stability of the warehouse door body 10, but also reduces noise and maintenance costs.

[0023] Example 2

[0024] See also Figure 1-Figure 5The utility model provides a technical solution: a heavy-duty hangar door with a guide mechanism, wherein the front edge of the guide plate 8 is fixedly connected to a fixing seat 12, a slot 13 is provided in the middle of the front side of the fixing seat 12, and a rotation slot 14 is provided on the left and right sides of the fixing seat 12, a short rod 15 is provided inside the rotation slot 14, and a fixing rod 16 is sleeved on the outside of the short rod 15, and a bolt 17 is fixedly connected to the front side of the fixing rod 16, a pressure ring 19 is sleeved on the outside of the bolt 17, and a nut 18 is fixedly connected to the front side of the pressure ring 19, and a mounting block 20 is slidably connected to the inside of the slot 13, and a mounting plate 21 is fixedly connected to one side of the mounting block 20, and a guide wheel 22 is provided on the front side of the mounting plate 21, and the fixing rod 16 is movably connected to the fixing seat 12 through the short rod 15.

[0025] Specifically, by rotating the nut 18, under the action of its internal thread and the external thread of the bolt 17, the retaining ring moves away from one side of the mounting plate 21, and the fixing rod 16 is rotated out from the inner limit groove, releasing the limit on the mounting plate 21, completing the disassembly of the guide wheel 22. Similarly, during installation, the mounting block 20 is slid into the groove 13 and the fixing rod 16 and the nut 18 are rotated. The fixing rod 16 rotates outside the short rod 15 and enters the rotating groove 14. The nut 18 fixes the pressure ring 19 to the mounting plate 21, thereby realizing the installation of the guide wheel 22. The guide wheel 22 can be loaded and unloaded by the mounting block 20, the mounting plate 21, the fixing rod 16, the bolt 17, the nut 18, and the pressure ring 19, and then it can be replaced when it is damaged, which also reduces the difficulty of maintaining the guide wheel 22.

[0026] Working principle: When the heavy-duty hangar door with a guide mechanism is in use, the motor 4 is started, and the motor 4 drives the screw rod 5 to rotate. The guide plate 8 slides in the lower guide rail 1 using its internal threaded hole 9, thereby realizing the movement of the door body 10. During the sliding process of the guide plate 8, the guide wheels 22 on both sides of the door body 10 roll on the support plate 7, which increases the stability of the door body 10 when opening and closing. At the same time, the rubber pad 11 plays a buffering role, reduces the impact force of the door body 10, and reduces the noise caused by the impact. The guide wheel 22 can be moved by the wire plate and the internal threaded hole 9 in conjunction with the motor 4 and the screw rod 5 to ensure that the door body runs smoothly on the track, reduce friction, and make the opening and closing of the door body 10 smoother. This design not only improves the operating efficiency and stability of the door body 10, but also reduces noise and Maintenance cost. When the damaged guide wheel 22 needs to be replaced, the nut 18 is rotated. Under the action of its internal thread and the external thread of the bolt 17, the clamping ring moves away from one side of the mounting plate 21, and the fixing rod 16 is rotated out from the inner limit groove, releasing the limit on the mounting plate 21, completing the removal of the guide wheel 22. Similarly, during installation, the mounting block 20 is slid into the groove 13 and the fixing rod 16 and nut 18 are rotated. The fixing rod 16 rotates outside the short rod 15 and enters the rotating groove 14. The nut 18 fixes the pressure ring 19 to the mounting plate 21, thereby realizing the installation of the guide wheel 22. The guide wheel 22 can be loaded and unloaded by the mounting block 20, the mounting plate 21, the fixing rod 16, the bolt 17, the nut 18, and the pressure ring 19, so that it can be replaced when it is damaged, and the difficulty of maintaining the guide wheel 22 can also be reduced.
