Description

Technical Field

[0001] This utility model belongs to the technical field of towing wheel structure, and in particular relates to a towing wheel structure for aircraft. Background Technology

[0002] Aircraft towing wheel clamps are an important device used when moving aircraft on the ground at airports. A wheel clamp is a device that can hold the aircraft wheels. It is mainly composed of mechanical structural components, including clamp arms and locking mechanisms. Its design purpose is to provide stable support and fixation by closely fitting the aircraft wheels, so that the aircraft can be towed safely.

[0003] Most existing aircraft towing wheel structures clamp the wheel using a clamping method, without considering that the lifting wheel may rotate. If the lifting wheel rotates on the device, it may slip off the device and cause danger. Therefore, we propose an aircraft towing wheel structure. Utility Model Content

[0004] The purpose of this utility model is to provide a gripping wheel structure for aircraft towing. The movement of the gripping frame pushes the lifting wheel, and then the lifting wheel is pushed onto the lifting platform until the lifting wheel contacts the contact arc plate. Then the gripping frame and the contact arc plate clamp the lifting wheel, which solves the problem that the existing gripping wheel mechanism may cause the lifting wheel to rotate.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model is a towing wheel structure for aircraft, including a support frame, a clamping mechanism and a lifting mechanism provided on the outer surface of the support frame;

[0007] The clamping mechanism includes a clamping frame. A threaded block one is fixedly connected to the side of the clamping frame away from the support frame. A threaded block two is fixedly connected to the side of the clamping frame away from the support frame. A threaded rod one is threadedly connected to the inner wall of the threaded block two. A connecting body is fixedly connected to the inner wall of the clamping frame. A moving rod is rotatably connected to the inner wall of the connecting body. A moving block is fixedly connected to the side of the moving rod away from the clamping frame. A moving plate is fixedly connected to the side of the moving blocks that are close to each other. A connecting plate is fixedly connected to the side of the support frame that is close to each other. A motor is fixedly connected to the side of the connecting plate that is close to the clamping frame. A threaded rod two is fixedly connected to the bottom output shaft of the motor via a coupling. A limit plate is fixedly connected to the side of the threaded rod two that is away from the clamping frame. An extension block is fixedly connected to the bottom of the support frame. A rotating column is rotatably connected to the inner wall of the extension block. A lifting platform is fixedly connected to one side of the rotating column that is close to each other. A contact arc plate is fixedly connected to the outer surface of the lifting platform. A connecting strip is fixedly connected to the outer surface of the contact arc plate. A rotating rod is rotatably connected to the inner wall of the connecting strip. There are two rotating rods in total. A friction disc is fixedly connected to one side of the rotating rods that is close to each other. The movement of the moving rod causes the clamping frame to move. The clamping frame then pushes the lifting wheel and clamps it stably. This achieves the effect of automatically allowing the lifting wheel to enter the device and clamping it to prevent the lifting wheel from slipping during aircraft towing, thus preventing a dangerous situation.

[0008] Furthermore, there are two clamping frames and two threaded blocks, and the outer surface of the moving rod is slidably connected to the inner wall of the support frame.

[0009] Furthermore, the outer surface of the second threaded rod penetrates the outer surface of the connecting plate and extends to the outside, and the outer surface of the second threaded rod is threadedly connected to the inner wall of the moving plate.

[0010] Furthermore, the lifting mechanism includes an extension column fixedly connected to the side of the moving block away from the moving plate. There are two extension columns in total. By connecting the extension columns to the moving block, the rack can be moved.

[0011] Furthermore, a connecting block is fixedly connected to the bottom of the extension column, and a rack is fixedly connected to the side of the connecting block near the clamping frame. A gear is engaged at the top of the rack, and the rack connects to the gear, thus enabling the gear to rotate.

[0012] Furthermore, the outer surface of the first gear is rotatably connected to the outer surface of the support frame, the side of the first gear away from the support frame is fixedly connected to the second gear, and the bottom of the second gear is meshed with the third gear.

[0013] Furthermore, an extension block two is rotatably connected to one side of the gear three that is close to each other. The top of the extension block two is fixedly connected to the bottom of the support frame. By connecting the support frame through the extension block two, the position of the gear three can be fixed.

[0014] Furthermore, a rotating rod two is fixedly connected to the outer surface of the gear three, and a lifting rod is fixedly connected to one side of the rotating rod two that is close to each other. The outer surface of the lifting rod is slidably connected to the inner wall of the lifting platform. The rotation of the gear three causes the rotating rod two to rotate, and then the rotation of the rotating rod two causes the lifting rod to lift the lifting platform, thereby transporting the lifting wheel into the trailer. This achieves the effect of lifting the lifting wheel to a horizontal position and preventing the tilted lifting wheel from slipping off the trailer.

[0015] This utility model has the following beneficial effects:

[0016] 1. This utility model incorporates a clamping frame. The lifting platform contacts the aircraft's lifting wheels, and then the two clamping frames are pushed. The clamping frames rotate on a moving rod via a connecting body. When the threaded block one on the clamping frame rotates into the two threaded blocks two, rotation stops. Then, the threaded rod one is rotated and tightened into the threaded blocks two, locking the two clamping frames. The movement of the moving rod causes the clamping frames to move, pushing the lifting wheels and clamping them securely. A friction disc then fixes the surface of the lifting wheels to prevent rotation. This achieves the effect of automatically inserting the lifting wheels into the device and fixing them to prevent rotation, thus preventing the lifting wheels from rotating and slipping off the device during aircraft towing, which could cause a hazard.

[0017] 2. This utility model incorporates a lifting rod. The rack and pinion mechanism causes gear one to rotate, which in turn drives gear two to rotate simultaneously. Gear two then drives gear three to rotate, which in turn drives rotating rod two to rotate. Rotating rod two, through the lifting rod, raises the lifting platform, ensuring the lifting wheels are stably positioned within the trailer's cargo box. The rotation of gear three causes rotating rod two to rotate, which in turn raises the lifting rod, thus transporting the lifting wheels into the trailer's cargo box. This achieves the effect of raising the lifting wheels to a horizontal position, preventing tilted lifting wheels from slipping off the trailer.

[0018] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0028] Please see Figure 1-5As shown, this utility model is a towing wheel structure for aircraft, including a support frame 101. A clamping mechanism 2 and a lifting mechanism 3 are provided on the outer surface of the support frame 101. The clamping mechanism 2 includes a clamping frame 201. A threaded block 202 is fixedly connected to the side of the clamping frame 201 away from the support frame 101. By connecting the clamping frame 201 to the threaded block 202, the two clamping frames 201 can be locked together. A threaded block 203 is fixedly connected to the side of the clamping frame 201 away from the support frame 101. A threaded rod 204 is threadedly connected to the inner wall of the threaded block 203. A connecting body 205 is fixedly connected to the inner wall of the clamping frame 201. The inner wall of the connecting body 205 is rotatably connected. A moving rod 206 is connected to a connecting body 205 via a clamping frame 201. The clamping frame 201 can then rotate via the connecting body 205. A moving block 219 is fixedly connected to the side of the moving rod 206 away from the clamping frame 201. A moving plate 218 is fixedly connected to the side of the moving blocks 219 that are close to each other. A connecting plate 208 is fixedly connected to the side of the support frame 101 that is close to each other. A motor 207 is fixedly connected to the side of the connecting plate 208 that is close to the clamping frame 201. The motor 207 is fixedly positioned by connecting the connecting plate 208. The output shaft at the bottom of the motor 207 is fixedly connected to a threaded rod 209 via a coupling. The threaded rod 209 is away from the clamping frame 201. A limit plate 210 is fixedly connected to one side of the support frame 101. An extension block 211 is fixedly connected to the bottom of the support frame 101. A rotating column 212 is rotatably connected to the inner wall of the extension block 211. The extension block 211 connects to the rotating column 212, allowing the lifting platform 213 to rotate. The lifting platform 213 is fixedly connected to the side of the rotating columns 212 that are close to each other. A contact arc plate 214 is fixedly connected to the outer surface of the lifting platform 213. A connecting strip 215 is fixedly connected to the outer surface of the contact arc plate 214. A rotating rod 216 is rotatably connected to the inner wall of the connecting strip 215. The connecting strip 215 connects to the rotating rod 216, so that when the lifting wheel presses against the rotating rod 216, the friction plate 217 will automatically clamp. On the lifting wheel, there are two rotating rods 216. A friction disc 217 is fixedly connected to one side of the rotating rods 216 that are close to each other. There are two clamping frames 201 and two threaded blocks 203. The friction disc 217 is connected to the rotating rod 216, so that the friction disc 217 can clamp the surface of the lifting wheel. The outer surface of the moving rod 206 is slidably connected to the inner wall of the support frame 101. The outer surface of the threaded rod 209 penetrates the outer surface of the connecting plate 208 and extends to the outside. The outer surface of the threaded rod 209 is threadedly connected to the inner wall of the moving plate 218. The moving plate 218 is connected to the threaded rod 209. When the threaded rod 209 rotates, it will cause the moving plate 218 to move backward.

[0029] The lifting mechanism 3 includes an extension column 301 fixedly connected to the side of the moving block 219 away from the moving plate 218. There are two extension columns 301. A connecting block 302 is fixedly connected to the bottom of the extension column 301. A rack 303 is fixedly connected to the side of the connecting block 302 near the clamping frame 201. The rack 303 is connected to the connecting block 302. Then the connecting block 302 will drive the rack 303 to move backward together. A gear 1 304 is meshed at the top of the rack 303. The outer surface of the gear 1 304 is rotatably connected to the outer surface of the support frame 101. A gear 2 305 is fixedly connected to the side of the gear 1 304 away from the support frame 101. A gear 3 306 is meshed at the bottom of the gear 2 305. The gear 3 306 is connected to the gear 2 305. Then the rotation of the gear 2 305 will cause the gear 3 306 to rotate as well.

[0030] The gear 306 is rotatably connected to the side of the gears that are close to each other. The top of the extension block 307 is fixedly connected to the bottom of the support frame 101. The outer surface of the gear 306 is fixedly connected to the rotating rod 308. The side of the rotating rod 308 that is close to each other is fixedly connected to the lifting rod 309. The outer surface of the lifting rod 309 is slidably connected to the inner wall of the lifting platform 213. The gear 306 connects to the rotating rod 308, and then the gear 306 will drive the rotating rod 308 to rotate together, thereby lifting the lifting rod 309 to lift the lifting platform 213.

[0031] One specific application of this embodiment is:

[0032] When the equipment is needed by the staff, it is mounted on a trailer, which then moves the aircraft via the device. The trailer first moves the device until the lifting platform 213 contacts the aircraft's lifting wheels. Then, the two clamping frames 201 are pushed, causing them to rotate on the moving rod 206 via the connecting body 205. The rotation stops when the threaded block 202 on the clamping frame 201 rotates into the two threaded blocks 203. Then, the threaded rod 204 is rotated to tighten it into the threaded blocks 203, thus securing the two clamping frames 201. 1. Lock the wheel, then start the motor 207. The motor 207 will rotate the threaded rod 209, causing the moving plate 218 to move backward. The moving plate 218, through the moving block 219, will drive the moving rod 206 backward, causing the two clamping frames 201 to move backward and push the lifting wheel. When the lifting wheel touches the rotating rod 216, the rotating rod 216 will move closer together, causing the friction disc 217 to press tightly against the lifting wheel. Then, the clamping frames 201, together with the contact arc plate 214, will clamp the lifting wheel tightly. This is achieved through the moving rod 2... The movement of 06 causes the clamping frame 201 to move, which in turn pushes the lifting wheel and clamps it securely. This allows the lifting wheel to automatically enter the device and is clamped, preventing it from slipping and causing a hazard during aircraft towing. Simultaneously, as the moving block 219 moves backward, it drives the extension column 301 backward. The extension column 301 then drives the rack 303 backward via the connecting block 302. The rack 303 then rotates gear one 304, which in turn drives gear two 305 to rotate simultaneously. Then, the rotation of gear 2 305 will drive gear 3 306 to rotate together. The rotation of gear 3 306 will drive rotating rod 2 308 to rotate. Rotating rod 2 308 will then lift the lifting platform 213 through lifting rod 309, so that the lifting wheel is stable in the trailer's cargo box. The rotation of gear 3 306 causes rotating rod 2 308 to rotate, and the rotation of rotating rod 2 308 will cause lifting rod 309 to lift the lifting platform 213, thereby transporting the lifting wheel into the trailer's cargo box. This achieves the effect of raising the lifting wheel to a horizontal position and preventing the tilted lifting wheel from slipping off the trailer.
