Description

Technical Field

[0001] The present invention relates to the field of aircraft maintenance, and more particularly to a vehicle for replacing aircraft wheels. Background Art

[0002] Aircraft tires are wheel parts used to bear the ground load of the aircraft and buffer the impact and vibration loads generated when the aircraft taxis on the ground. Since aircraft tires bear a large load during takeoff and landing, there is a large friction between them and the ground. After multiple trips, aircraft tires need to be inspected and replaced regularly to avoid flight safety hazards caused by tire wear during flight.

[0003] At present, when replacing aircraft tires, the aircraft first uses a lifting device to lift the position where the aircraft tire needs to be replaced to a suitable position, then manually removes the tire to be replaced, lifts the new tire to a height similar to the aircraft axle, and manually moves the new tire so that its installation axis matches the aircraft axle to install the new tire. However, due to the heavy weight of aircraft tires, this method of replacing aircraft tires requires a lot of manpower, resulting in low efficiency in replacing aircraft tires. Utility Model Content

[0004] In order to reduce the manpower consumed in replacing aircraft tires and improve the efficiency of replacing aircraft tires, the present application provides a vehicle for replacing aircraft wheels.

[0005] The present application provides a vehicle for replacing aircraft wheels using the following technical solution:

[0006] A vehicle for replacing aircraft wheels comprises mounting rods which are arranged opposite to each other, a lifting assembly for lifting the height of the automobile wheels being arranged between the mounting rods, a fixing rod being arranged between the mounting rods, a positioning column being arranged on the fixing rod, the positioning column being arranged to be retractable, the mounting height of the positioning column being consistent with the height of the aircraft wheel axle after being lifted, the positioning column being able to be inserted into the mounting shaft of the aircraft tire, and a universal locking wheel for driving the mounting rod to move being arranged at the bottom of the mounting rod.

[0007] By adopting the above technical solution, when it is necessary to replace the aircraft tire, the vehicle is pushed to the vicinity of the aircraft tire, and the aircraft tire is lifted to the height of the positioning column using the lifting assembly, so that the positioning column can pass through the installation axis of the aircraft tire, and then the vehicle is pushed to be placed on the aircraft wheel axle. Since the height of the positioning column is consistent with the aircraft wheel axle, the position of the positioning column is aligned with the aircraft wheel axle, so that the installation axis of the aircraft tire and the aircraft wheel axle can be ensured to correspond, and then the aircraft tire can be installed on the aircraft wheel axle. There is no need to manually move the tire to align its installation axis with the aircraft wheel axle, thereby reducing the manpower consumed in replacing the aircraft tire and improving the efficiency of replacing the aircraft tire.

[0008] Optionally, the lifting assembly includes a telescopic rod installed between the mounting rods, the telescopic rod is fixedly connected to a first hydraulic rod, the first hydraulic rod is connected to an air release valve, a foot pedal is installed at the bottom of the first hydraulic rod, connecting rods are arranged on both sides of the top end of the telescopic part of the first hydraulic rod, each connecting rod is rotatably connected to a sprocket, each sprocket is meshed with a chain, one end of the chain is connected to the fixed rod, and the other end of the chain is connected to a lifting column for lifting the aircraft tire.

[0009] By adopting the above technical solution, when it is necessary to use the lifting assembly to lift the aircraft tire, the lifting column is first placed between the bottom of the aircraft tire and the ground, and the foot pedal is pressed to compress the liquid in the first hydraulic rod, so that the moving part of the first hydraulic rod rises, driving the sprocket to rise and rotate at the same time, driving the chain to rise, one end of the chain is fixed, and the other end drives the lifting column to rise, so that the lifting column drives the aircraft tire to rise; when it is necessary to lower the lifting column, the air release valve is screwed to lower the lifting column, and the next operation can be continued.

[0010] Optionally, an anti-skid sleeve is installed on the outer side of the lifting column to increase the friction between the lifting column and the aircraft tire.

[0011] By adopting the above technical solution, when a lifting column is used to lift an aircraft tire, in order to prevent the aircraft tire from falling off the lifting column due to the small friction between the aircraft tire and the lifting column, the provision of the anti-slip sleeve increases the friction between the lifting column and the aircraft tire.

[0012] Optionally, the diameter of the locating post is the same as the diameter of the aircraft tire mounting shaft.

[0013] By adopting the above technical solution, when the positioning column is inserted into the installation shaft of the aircraft tire, the positioning column can be directly aligned with the aircraft axle, and then the installation rod can be pushed at the same time, so that the aircraft tire can be directly installed on the aircraft axle along the positioning column, further saving manpower for replacing aircraft tires and further improving the efficiency of replacing aircraft tires.

[0014] Optionally, a fixing plate is provided near the top of the mounting rod, and a second hydraulic rod is installed at both ends of the fixing plate, and a movable end of the second hydraulic rod is fixedly connected to the mounting rod.

[0016] Optionally, two ends of the fixed rod are slidably connected with sliding rods, and one end of the sliding rod away from the fixed rod is fixedly connected to the mounting rod.

[0017] By adopting the above technical solution, when the second hydraulic rod drives the mounting rod to move away from each other, the mounting rod drives the sliding rod to move, so that the fixed rod can also change its length according to aircraft tires of different sizes, and the chain is not connected to the sliding rod, so the length of the fixed rod can be adjusted without affecting the function of the lifting assembly.

[0018] Optionally, a limit assembly is installed on the side of the mounting rod away from the locking universal wheel. The limit assembly includes a mounting seat mounted on the mounting rod, a limit rod is passed through the mounting seat, a spring is passed through the limit rod, one end of the spring is fixedly connected to one side of the mounting seat, and the other end is fixedly connected to the limit rod. A fixing block for fixing the position of the limit rod is also fixedly connected to the mounting rod, and the fixing block is provided with a mounting groove for the limit rod to be embedded in.

[0019] By adopting the above technical solution, under normal conditions, when no pressure is applied to the spring, the limit rod is directed toward the side of the mounting rod away from the aircraft tire; when the aircraft tire needs to be limited, the limit rod is pulled so that the limit rod compresses the spring, and the limit rod is rotated so that the limit rod abuts against the aircraft tire, and then the limit rod is embedded in the fixing block to fix the rotation position of the limit rod, thereby fixing the position of the aircraft tire.

[0020] Optionally, a handle is fixedly connected to a side of each mounting rod away from the aircraft tire, and the handle is in a semicircular arc shape.

[0021] By adopting the above technical solution, when it is necessary to push the mounting rod to move the aircraft tire to the desired location, the handle can be pushed instead of directly pushing the mounting rod to move it, and the handle is set to a semicircular arc shape, which is more convenient and makes the transportation personnel comfortable compared to the mounting rod with edges.

[0022] In summary, the present application includes at least one of the following beneficial technical effects:

[0023] 1. By setting the mounting rod, lifting assembly, fixing rod, positioning column and universal locking wheel, when the aircraft tire needs to be installed on the aircraft axle, the vehicle is moved to the vicinity of the aircraft tire through the universal locking wheel, and the aircraft tire is lifted to a certain height by using the lifting assembly so that the positioning column can pass through the mounting shaft of the aircraft tire. Since the height of the positioning column is consistent with that of the aircraft axle, when the positioning column can pass through the mounting shaft, the mounting shaft of the aircraft tire is aligned with the aircraft axle, and then the vehicle is moved to align the mounting shaft with the aircraft axle, and the aircraft tire can be replaced. This method does not require manual movement of the tire to align the mounting shaft with the aircraft axle, thereby reducing the manpower consumed in replacing the aircraft tire and improving the efficiency of replacing the aircraft tire;

[0029] The following is combined with Figure 1-2 This application is described in further detail.

[0030] The embodiment of the present application discloses a vehicle for replacing aircraft wheels.

[0031] Reference Figure 1 A vehicle for replacing aircraft wheels comprises two mounting rods 1, which are arranged opposite to each other, and the cross-section of the two mounting rods 1 is L-shaped. A lifting assembly 2 for lifting the height of the automobile wheel and a fixing rod 3 for fixing the relative positions of the two mounting rods 1 are arranged between the two mounting rods 1. A positioning column 4 is vertically fixed to the fixing rod 3, and the positioning column 4 is arranged to be retractable. The height of the positioning column 4 is consistent with the height of the aircraft wheel axle after being lifted. Two universal locking wheels 5 for driving the mounting rods 1 to move are arranged at the bottom of the two mounting rods 1.

[0032] When the aircraft tire 13 needs to be replaced, the vehicle is pushed to the vicinity of the new aircraft tire 13, the lifting assembly 2 is operated, the aircraft tire 13 is lifted to a suitable position, and the positioning column 4 is stretched so that the positioning column 4 can pass through the installation axis of the aircraft tire 13. If it cannot pass through, the height of the aircraft tire 13 needs to be adjusted again until the positioning column 4 can pass through the installation axis. Because the height of the positioning column 4 is consistent with that of the aircraft axle, after the positioning column 4 passes through the installation axis, the height of the installation axis is consistent with that of the aircraft axle, the positioning column 4 is retracted, the aircraft tire 13 is pushed to the aircraft axle, and the aircraft tire 13 is installed. This installation method does not require manual movement of the tire so that its installation axis is aligned with the aircraft axle, thereby reducing the manpower consumed in replacing the aircraft tire 13 and improving the efficiency of replacing the aircraft tire 13.

[0033] The diameter of the positioning column 4 is the same as the diameter of the mounting shaft of the aircraft tire 13. When the positioning column 4 is inserted into the mounting shaft of the aircraft tire 13, the outer wall of the positioning column 4 abuts against the inner wall of the mounting shaft; during installation, the vehicle is moved to the vicinity of the aircraft axle, and the positioning column 4 is pulled outward so that the positioning column 4 abuts against the aircraft axle, and is aligned so that the positioning column 4 completely corresponds to the aircraft axle. After alignment, the positioning column 4 is retracted, and the vehicle is pushed to install the aircraft tire 13, which further saves manpower for replacing the aircraft tire 13 and further improves the efficiency of replacing the aircraft tire 13.

[0034] Reference Figure 2 The lifting assembly 2 includes a telescopic rod 21 installed between the two mounting rods 1, both sides of the telescopic rod 21 are telescopic ends, and the telescopic ends are fixedly connected to the inner sides opposite to the two mounting rods 1. A first hydraulic rod 22 is fixedly connected to the fixed part of the telescopic rod 21, and an air release valve 23 is threadedly connected to the outer side of the fixed part of the first connecting rod 25. A foot pedal 24 is installed at the bottom of the first hydraulic rod 22, and the foot pedal 24 is connected to the first hydraulic rod 22. Connecting rods 25 are fixedly connected to both sides of the telescopic end of the first hydraulic rod 22, and each connecting rod 25 is rotatably connected to a sprocket 26, and each sprocket 26 is meshed with a chain 27. One end of the chain 27 is fixedly connected to the fixed rod 3, and the other end of the chain 27 is fixedly connected to a lifting column 28, and the outer surface of the lifting column 28 is wrapped with an anti-slip sleeve 6.

[0035] When it is necessary to lift the aircraft tire 13, the lifting column 28 is first placed in the gap between the bottom of the aircraft tire 13 and the ground, and then the foot pedal 24 is pressed to increase the pressure in the first hydraulic rod 22, so that the liquid in the first hydraulic rod 22 is compressed, and the moving rod of the first hydraulic rod 22 starts to move upward, driving the connecting rod 25 to move upward, the connecting rod 25 drives the sprocket 26 to rotate and move upward, the sprocket 26 drives the chain 27 to move upward, and the chain 27 pulls the lifting column 28 to make the lifting column 28 rise, and the lifting column 28 makes the aircraft tire 13 rise. The provision of the anti-skid sleeve 6 increases the friction between the lifting column 28 and the aircraft tire 13, so as to prevent the aircraft tire 13 from falling off the lifting column 28 due to the small friction between the aircraft tire 13 and the lifting column 28; when unloading the old aircraft tire 13, the air pressure in the first hydraulic rod 22 can be reduced by screwing the deflation valve 23, so that the lifting column 28 descends.

[0036] Reference Figure 1 , the inner sides of the two mounting rods 1 are fixedly connected with a second hydraulic rod 8, and are fixedly connected with the telescopic ends of the second hydraulic rod 8, and a fixing plate 7 is fixedly connected between the two second connecting rods 25, and the fixing plate 7 is used to connect the two second hydraulic rods 8. The two ends of the fixed rod 3 are slidably connected with sliding rods 9, and the end of the sliding rod 9 away from the fixed rod 3 is fixedly connected with the mounting rod 1. When it is necessary to lift the aircraft tire 13, the car is moved behind the aircraft tire 13, and the two second hydraulic rods 8 are started at the same time, and adjusted according to the size of the aircraft tire 13, so that the two mounting rods 1 move back to back, and the mounting rod 1 drives the sliding rod 9 to move, so that the fixed rod 3 can also change its length according to the different sizes of the aircraft tire 13; when the car is not needed, the second telescopic rod 21 can be started again, so that the two mounting rods 1 move closer to each other, reducing the footprint of the car and saving more placement space.

[0037] A limiting assembly 10 for limiting the position of the aircraft tire 13 is installed on the upper surface of the bottom of the two mounting rods 1. The limiting assembly 10 includes a mounting seat 101 mounted on the mounting rod 1 away from the side where the locking universal wheel is installed. A limiting rod 102 is penetrated on the mounting seat 101. The limiting rod 102 is U-shaped. A spring 103 is fixedly connected to one side of the mounting seat 101. The spring 103 is penetrated on the limiting rod 102. One end of the spring 103 away from the mounting seat 101 is fixedly connected to the limiting rod 102. A fixing block 104 is fixedly connected to the side of the mounting seat 101 away from the spring 103. The fixing block 104 is used to fix the position of the limiting rod 102. The fixing block 104 is provided with a mounting groove 11 for the limiting rod 102 to be embedded.

[0038] Under normal circumstances, when the spring 103 is not under pressure, the U-shaped opening of the limiting rod 102 faces away from the position between the two mounting rods 1; when the position of the aircraft tire 13 needs to be limited, the end of the limiting rod 102 farther from the aircraft tire 13 is pulled so that the limiting rod 102 compresses the spring 103, and then the limiting rod 102 is rotated so that the unpulled side of the limiting rod 102 abuts against the aircraft tire 13, and the pulled side is embedded in the mounting groove 11 to fix the position of the aircraft tire 13.

[0039] Reference Figure 1 The two mounting rods 1 are fixedly connected with a handle 12 on the side away from the mounting rod 1 for mounting the aircraft tire 13, and the cross section of the handle 12 is C-shaped. When the car needs to be pushed to move the aircraft tire 13 to a suitable position, the handle 12 can be directly held, which is more comfortable and convenient than directly holding the mounting rod 1.

[0040] The implementation principle of the vehicle for replacing aircraft wheels in the embodiment of the present application is as follows: when the aircraft tire 13 needs to be replaced, hold the handle 12 and push the vehicle to the vicinity of the new aircraft tire 13, and simultaneously start the two second hydraulic rods 8, and adjust them according to the size of the aircraft tire 13, so that the two mounting rods 1 move in opposite directions, and the mounting rods 1 drive the sliding rods 9 to move. After the size is adjusted, the lifting column 28 is placed in the gap between the bottom of the aircraft tire 13 and the ground, and then the foot pedal 24 is pressed to move the first hydraulic rod 22 upward, drive the lifting column 28 to make the lifting column 28 rise, and the lifting column 28 makes the aircraft tire 13 rise. Stretch the positioning column 4 so that the positioning column 4 can pass through the installation shaft of the aircraft tire 13. If it cannot pass through, the height of the aircraft tire 13 needs to be adjusted again until the positioning column 4 can pass through the installation shaft. At this time, the outer wall of the positioning column 4 abuts against the inner wall of the installation shaft; then pull the limit rod 102 so that the limit rod 102 compresses the spring 103, then rotate the limit rod 102 so that the other end of the limit rod 102 abuts against the aircraft tire 13, and embed the pulled end into the installation groove 11 to fix the position of the aircraft tire 13. During installation, move the car to the vicinity of the aircraft axle so that the positioning column 4 abuts against the aircraft axle. After alignment, retract the positioning column 4 and push the car to install the aircraft tire 13.

[0041] When unloading the old aircraft tire 13, the air pressure in the first hydraulic rod 22 can be reduced by screwing the deflation valve 23, so that the lifting column 28 is lowered. When the car is not needed, the second telescopic rod 21 can be started again so that the two mounting rods 1 can move closer.

[0042] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
