[0019] The clamping surface of the clamping push plate 50 is an arc surface, so as to clamp the aircraft wheel 60.

[0020] The clamping surface of the clamping push plate 50 is provided with a roller 501.

[0021] The front pressing plate 33 is a hydraulic connecting rod structure.

[0022] The wheel holding device of the aircraft towing vehicle further comprises an anti-skid block 21 installed on the front part of the bottom plate of the base turntable, which can cope with various emergencies in the process of towing the aircraft to slide, and ensures the safety of the aircraft towing.

[0023] In combination with Figure 1 , Figure 2 , Figure 3 The working principle of the wheel holding device of the aircraft towing vehicle provided by the present application is described as follows:

[0024] First, according to the position of the aircraft wheel 60, the towing vehicle driver drives the towing vehicle equipped with the present wheel holding device to the working position, so that the aircraft wheel 60 is in the same straight line as the center axis of the vehicle body 10 of the present device, then, under the control of the towing vehicle control system, the device is started, the opening and closing hydraulic rod 41 on the No. 5 hydraulic cylinder 401 is extended backward, at the same time, the rotating motor 411 is started to open the clamping push plate 50 outward, then, under the cooperation of the No. 1 hydraulic cylinder 402, the No. 2 hydraulic cylinder 403 and the No. 3 hydraulic cylinder 404, the rear end of the load bearing bottom plate 30 is driven to turn down, so that the load bearing bottom plate 30 is in an inclined state, then the towing vehicle retreats until the shovel plate 31 contacts the lower part of the aircraft wheel 60. When the aircraft wheel 60 enters the working range of the No. 5 hydraulic cylinder 401, the rotating motor 411 works, the opening and closing hydraulic rod 41 on the No. 5 hydraulic cylinder 401 is retracted at the same time, and the angle of the clamping push plate 50 is adjusted, so that the clamping push plate 50 contacts the rear part of the aircraft wheel 60, at this time, the electric push rod 421 pushes the latch to insert into the pin hole on the clamping push plate 50, and the clamping push plate 50 is mechanically locked. Subsequently, the towing vehicle advances, the aircraft wheel 60 moves to the support plate 32 under the action of the shovel plate 31 and the clamping push plate 50, until the front part of the aircraft wheel 60 contacts the front pressing plate 33, at this time, the No. 4 hydraulic cylinder 405 works, so that the front pressing plate 33 and the clamping push plate 50 cooperate to hold the aircraft wheel 60. The No. 1 hydraulic cylinder 402, the No. 2 hydraulic cylinder 403 and the No. 3 hydraulic cylinder 404 are retracted, driving the rear end of the load bearing bottom plate 30 to turn up, so that the aircraft wheel 60 is lifted. During this period, the No. 4 hydraulic cylinder 405 and the No. 5 hydraulic cylinder 401 can ensure that the clamping force is sufficient, the rotating motor 411 adjusts the angle of the clamping push plate 50 to ensure that the aircraft wheel 60 will not fall off. When the load bearing bottom plate 30 lifts the aircraft wheel 60 and turns to the horizontal position, the No. 1 hydraulic cylinder 402, the No. 2 hydraulic cylinder 403 and the No. 3 hydraulic cylinder 404 stop retraction, and the wheel holding process is completed.

[0025] When the aircraft needs to turn under the traction of the towing vehicle, the pilot controls the turning of the aircraft wheel 60 to control the overall turning action of the towing vehicle. The pilot sends a turning instruction to the aircraft wheel 60 in the cockpit, the aircraft wheel 60 receives the instruction and deflects, the turning angle sensor on the base turntable detects the deflection angle of the aircraft wheel 60 and sends the information to the towing vehicle control system, the control system controls the wheels 11 to turn accordingly, thereby completing the turning action of the towing vehicle.

[0026] When the aircraft needs to accelerate under the traction of the tractor, the pilot issues an acceleration command in the cab, at which time the rotation angle sensor installed on the base turntable senses the movement of the aircraft wheel 60 and sends the information to the tractor control system, which first issues a command to the No. 5 hydraulic cylinder 401 and the clamping push plate 50 to increase the clamping force to ensure the safety of the aircraft wheel 60 during acceleration, and then sends an acceleration command to the wheels 11, thereby completing the acceleration action of the tractor.

[0027] When the aircraft runs to the correct position under the traction of the tractor, the tractor needs to stably lower the aircraft wheel 60. First, the No. 1 hydraulic cylinder 402, the No. 2 hydraulic cylinder 403, and the No. 3 hydraulic cylinder 404 work together to slowly tilt the rear end of the load-bearing bottom plate 30 downward, and when the load-bearing bottom plate 30 runs to the predetermined position, the hydraulic rod on the No. 4 hydraulic cylinder 405 retracts, the opening and closing hydraulic rod 41 on the No. 5 hydraulic cylinder 401 extends to the designated position, and the electric push rod 421 retracts to open the latch. The rotation motor 411 rotates to drive the clamping push plate 50 to rotate outward, releasing the aircraft wheel 60, and then the tractor moves forward to leave the aircraft wheel 60, and all the hydraulic cylinders on the hydraulic cylinder group 40 work to drive the load-bearing bottom plate 30 and the clamping push plate 50 to return to the original state.

[0028] In addition, during the above operation process, the first and second force sensors can be used to detect the clamping force between the load-bearing bottom plate 30 and the clamping push plate 50 and the aircraft wheel 60 in real time, thereby ensuring the safety of clamping the aircraft wheel 60. A rotation angle sensor is installed on the base turntable, which detects the rotation angle data of the aircraft wheel 60 when turning and feeds back to the aircraft tractor control system. The use of the rotation angle sensor can realize that only the aircraft pilot controls the rotation of the aircraft wheel 60 during turning, and then the vehicle body 10 on the device follows, the operation is accurate and stable, saves manpower, and reduces the possibility of accidents. At the same time, the present wheel clamping device uses a hydraulic system for control, which is safe to operate, and the hydraulic system and pressure sensor can be used to monitor the movement state of the wheel clamping device in real time.

[0029] The aircraft tractor wheel clamping device provided by the present application has the following advantages:

[0030] When the aircraft wheel 60 is clamped and fixed as a whole with the base turntable, the aircraft and the tractor can be followed, and the aircraft can be driven forward and backward by the tractor, and the turning, acceleration, and deceleration of the tractor can be controlled by controlling the rotation of the aircraft wheel 60. The turning process is controlled by the aircraft pilot, which not only saves manpower, but also reduces the possibility of accidents and ensures the safety of traction.

[0031] The rear part of the support plate 32 supported on the load bearing bottom plate 30 is located at the outer end of the opening 12, and the support plate 32 is driven to overturn by three sets of hydraulic cylinders, in the initial state, the shovel plate 31 at the rear end can be in contact with the lower part of the aircraft wheel 60, so that the friction between the wheel 11 and the ground can be increased by using part of the mass of the aircraft, thereby reducing fuel consumption and prolonging the service life of the wheel holding device, the shovel plate 31 installed at the rear end of the support plate 32 can shovel the aircraft wheel 60, and the support plate 32 is in a horizontal state in the in-place state to support the aircraft wheel 60, and the aircraft wheel 60 is smoothly transitioned onto the load bearing bottom plate 30 and lifted, and the working process is stable.

[0032] The hydraulic cylinder set 40 and the clamping push plate 50 cooperate with each other and can be linked with the overturning action of the load bearing bottom plate 30, specifically, the aircraft wheel 60 is clamped by using the clamping push plate 50 and the front pressing plate 35 first, then the load bearing bottom plate 30 is overturned to the in-place state, in this process, the No. 4 hydraulic cylinder 405 and the No. 5 hydraulic cylinder 401 are flexibly retracted to make the clamping push plate 50 push the aircraft wheel 60 to move to the designated position, the clamping push plate 50 is locked, and finally the aircraft wheel 60 is clamped and lifted, the clamping push plate 50 can rotate with the hydraulic cylinder to maximize the contact area with the aircraft wheel 60, in addition, the front pressing plate 33 can adjust the position according to the state of the aircraft wheel 60, and work in cooperation with the clamping push plate 50 to fit the aircraft wheel 60, the working process of the present wheel holding device is different from the simple push-pull mode, and the clamping push plate 50 is in contact with the aircraft wheel 60 during the lifting of the aircraft wheel 60, so that vibration can be reduced, and the working process is more stable.

[0033] By arranging the rotating motor 411, the clamping push plate 50 can slightly adjust the angle during the process of pushing the aircraft wheel 60, so as to better fit the aircraft wheel 60, further reduce vibration, and ensure the stability of the working process.

[0034] In summary, the present wheel holding device has the advantages of simple operation, safety, stable working, long service life, high lifting height, wide application range and the like.

[0035] The fixed positions of the hydraulic cylinders are not limited, such as Figure 1As shown, in an embodiment, the projections of the two No. 1 hydraulic cylinders 402 on the base turntable are symmetrically arranged relative to the central axis of the vehicle body 10 to ensure that the load bearing platform 30 stably performs the pitching action; the two No. 2 hydraulic cylinders 403 and the No. 3 hydraulic cylinder 404 are fixed on the vehicle body 10 and are hinged with the load bearing platform 30, which can ensure the lifting and falling of the load bearing platform 30; the No. 4 hydraulic cylinder 405 is fixed on the base turntable, the upper end of which is connected with the front pressing plate 33 to ensure that the aircraft wheel 60 is tightly held after being in place. The No. 5 hydraulic cylinder 401 is fixed on the base turntable to move the aircraft wheel 60 to the load bearing platform 30 and cooperate with the No. 4 hydraulic cylinder 405 to tightly hold the aircraft wheel 60.

[0036] The shovel plate 31 arranged on the load bearing platform 30 is easier to contact the lower part of the aircraft wheel 60, which prepares for the lifting action. At the same time, the part of the mass of the aircraft can increase the friction between the wheel 11 and the ground, reduce fuel consumption, and prolong the service life of the wheel holding device. The aircraft wheel 60 can be more smoothly transitioned to the support plate 32 through the shovel plate 31. In the in-place state, the aircraft wheel 60 can be limited by the front pressing plate 33, and the clamping push plate 50 and the front pressing plate 33 hold the aircraft wheel 60, thereby facilitating the subsequent traction action. The front pressing plate 33 is a hydraulic connecting rod structure, which can limit the aircraft wheel 60 in multiple directions to ensure the stability of the aircraft wheel 60 after being in place, reduce unnecessary vibration during traction, and improve the stability of the working process.

[0037] The clamping surface of the clamping push plate 50 is designed as a curved surface, which can make the clamping push plate 50 better fit the tire surface of the aircraft wheel 60, reduce unnecessary vibration during pushing, tightly hold the aircraft wheel 60 after being in place, avoid the movement of the aircraft wheel 60 during traction, ensure the synchronous operation of the tractor and the aircraft, more stably complete the forward, backward and turning actions, and improve the traction efficiency and accuracy.

[0038] By arranging the roller 501 on the clamping surface of the clamping push plate 50, the friction between the clamping push plate 50 and the aircraft wheel 60 can be reduced, so that the aircraft wheel 60 can stably move forward during the process of pushing the aircraft wheel 60 by the clamping push plate 50. The tractor and the aircraft are operated synchronously, and various traction actions are more stably completed.

[0039] By installing a rotating motor 411 on one side of the clamping push plate 50 and leaving a pin hole on the other side of the clamping push plate 50, when the clamping push plate 50 holds the aircraft wheel 60, the electric push rod 421 pushes the pin to mechanically lock the clamping push plate 50, which avoids the aircraft wheel 60 from being pulled out due to sudden accidents during traction, thereby causing a safety accident of the aircraft.
