[0033] like Figure 6 As shown, the traction frame 6 is arranged in a T-shaped structure, a plurality of slots 601 are provided on one side of the traction frame 6, the inner wall of the slot 601 is covered with a rubber pad, an inclined surface is provided at the opening of the slot 601 of the traction frame 6, the inner wall of the slot 601 is adapted to the front landing gear 9 of the aircraft, and two limit blocks 602 are provided at the opening of the slot 601 in a symmetrical structure and slidingly cooperated, and an inclined surface is provided at one end of the limit block 602 located in the slot 601, a tension spring 603 is fixedly connected to the limit block 602, and the other end of the tension spring 603 is fixedly connected to the traction frame 6, and the other end of the limit block 602 is fixedly connected to a contact plate 604. The electric push rod 504 is used to drive the traction frame 6 to move upward, so that the traction frame 6 is aligned with the front landing gear 9 of the aircraft, and then the hydraulic cylinder 501 is used to drive the control frame 5 to retract a distance, so that the inclined surface of the limit block 602 on the traction frame 6 contacts and separates from the front landing gear 9 of the aircraft, and when the front landing gear 9 of the aircraft is inserted into the slot 601, the limit block 602 limits the front landing gear 9 of the aircraft under the action of the tension spring 603. The inner wall of the slot 601 is covered with a rubber pad to protect the surface of the front landing gear 9 of the aircraft.

[0034] like Figure 7 As shown, the adjustment mechanism 7 includes a motor 701, which is fixedly connected to the control frame 5, and a toothed disc 702 is fixedly connected to the output end of the motor 701, and a plurality of gears 703 are meshingly provided on one side of the toothed disc 702.

[0035] One end of the gear 703 is connected and fixed with a universal joint 704, and a fixing frame 705 is rotatably connected to the universal joint 704.

[0036] like Figure 8 As shown, the drying mechanism 8 includes an air guide ring 801, which is fixedly connected to the inner wall of the storage seat 2, an air intake pipe 802 is fixedly connected to one side of the top of the air guide ring 801, and an air pump 803 is fixedly connected to the other end of the air intake pipe 802, and the air pump 803 is fixedly connected to the inner wall of the storage seat 2, and a rotating ring 804 is rotatably connected to the inner wall of the air guide ring 801, and a plurality of jet heads 805 are fixedly connected to one side of the rotating ring 804 in an annular structure, and one end of the jet head 805 is arranged in an inclined structure. The inclined structure of one end of the jet head 805 realizes that the rainwater on the traction frame 6 is blown to the outside of the storage seat 2 to prevent the rainwater from falling into the storage seat 2.

[0037] An annular rack 806 is fixedly connected to the other side of the rotating ring 804, and a driven wheel 807 is meshed and driven on one side of the annular rack 806. The driven wheel 807 is rotatably connected to the inner wall of the storage seat 2, and a driving wheel 808 is fixedly connected to the upper part of the driven wheel 807. The driving wheel 808 is meshed and driven with the transmission rack 503. The air pump 803 is used to inject high-pressure gas into the air guide ring 801 through the air inlet pipe 802, and then it is sprayed through the spray head 805 on the rotating ring 804. When the operating frame 5 is retracted into the storage seat 2, the transmission rack 503 at the bottom of the operating frame 5 will drive the driving wheel 808 to rotate, so that the driving wheel 808 drives the driven wheel 807 to rotate, so that the driven wheel 807 drives the rotating ring 804 connected to the annular rack 806 to rotate, so that the high-pressure gas sprayed by the spray head 805 dries the moisture on the traction frame 6.

[0038] By arranging a drying mechanism 8 in the storage seat 2, when the traction control mechanism of the vehicle body 1 is used to tow the aircraft on a rainy day, it can drive the rotating ring 804 to rotate while retracting and hiding it, so that multiple nozzles 805 that spray high-pressure gas surround the traction control mechanism to dry the rainwater, reducing the time that moisture is retained on the mechanical parts, thereby effectively reducing the risk of corrosion and rust of metal parts and maintaining the vehicle body 1 in an efficient working state.

[0039] Working principle: when it is necessary to tow an aircraft, first adjust the vehicle body 1 to align with the nose of the aircraft, and then use the hydraulic cylinder 501 to drive the control frame 5 to move out of the storage seat 2. At this time, the adjustment rack 502 connected to the control frame 5 will drive the adjustment wheel 403 to rotate, so that the adjustment wheel 403 drives the connected universal joint assembly 401 to rotate, so that the universal joint assembly 401 drives the connected worm 402 to rotate, so that the worm 402 drives the blocking cover 3 connected to the worm wheel 301 to open;

[0040] Then, after the control frame 5 is moved out, the electric push rod 504 is used to drive the traction frame 6 to move up, so that the traction frame 6 is aligned with the front landing gear 9 of the aircraft, and then the hydraulic cylinder 501 is used to drive the control frame 5 to be retracted for a distance, so that the inclined surface of the limit block 602 on the traction frame 6 contacts and separates from the front landing gear 9 of the aircraft. When the front landing gear 9 of the aircraft is inserted into the slot 601, the limit block 602 limits the front landing gear 9 of the aircraft under the action of the tension spring 603, thereby ensuring a stable connection between the traction frame 6 and the front landing gear 9 of the aircraft.

[0041] Then, the vehicle body 1 is used to tow the aircraft. After the towing is completed, the motor 701 is used to drive the connected gear plate 702 to rotate, so that the gear plate 702 drives the universal joint 704 connected to the gear 703 to rotate, so that the universal joint 704 drives the connected adjustment rod 706 to rotate, so that the two ends of the adjustment rod 706 will contact and squeeze the contact plate 604, so that the contact plate 604 drives the connected limit block 602 to move, and then the hydraulic cylinder 501 drives the control frame 5 to move outward, so that the traction frame 6 is removed from the front landing gear 9 of the aircraft, and then the electric push rod 504 is used to drive the traction frame 6 to move down and reset;

[0042] Then, on a rainy day, first use the air pump 803 to inject high-pressure gas into the air guide ring 801 through the air inlet pipe 802, and then spray it out through the nozzle 805 on the rotating ring 804. Then, when the operating frame 5 is retracted into the storage seat 2, the transmission rack 503 at the bottom of the operating frame 5 will drive the driving wheel 808 to rotate, so that the driving wheel 808 drives the driven wheel 807 to rotate, so that the driven wheel 807 drives the rotating ring 804 connected to the annular rack 806 to rotate, so that the high-pressure gas sprayed by the nozzle 805 dries the moisture on the traction frame 6. Then, when the operating frame 5 is completely retracted into the storage seat 2, the cover 3 will be automatically closed through the opening and closing mechanism 4.
