[0030] Referring to Figure 1 , an aircraft tire transport vehicle includes a U-shaped frame 1, two rolling pipes 2, two rollers 3, a handrail frame 4, and a support frame 5.

[0031] Referring to Figure 1 and Figure 3 , the U-shaped frame 1 includes two longitudinal portions 1a and a transverse portion 1b connecting the two longitudinal portions 1a.

[0032] Referring to Figure 1 and Figure 2 , the two rolling pipes 2 are rotatably connected to the two longitudinal portions 1a of the U-shaped frame 1 around longitudinal axes, i.e., the orientations of the rolling pipes 2 are the same as the orientations of the longitudinal portions 1a. With respect to the connection positions of the rolling pipes 2 on the longitudinal portions 1a, the longitudinal portions 1a are divided into a first segment 1a1 away from the transverse portion 1b and a second segment 1a2 close to the transverse portion 1b, and the rolling pipes 2 are connected to the first segment 1a1. More specifically, a first connecting block 1a3 is welded and fixed to a position close to the middle of the longitudinal portion 1a, and a second connecting block 1a4 is detachably connected to a first end of the longitudinal portion 1a. An axle is arranged in the rolling pipe 2, and the two ends of the axle are rotatably connected to the first connecting block 1a3 and the second connecting block 1a4 using bearings.

[0033] Please refer to Figure 3 Two rolling tubes 2 are used for placing the tire. That is, in the top view, the axes of the two rolling tubes 2 are between the axes of the two longitudinal sections la. The rolling tubes 2 can be higher than the longitudinal sections la or flush with the longitudinal sections la.

[0034] The rolling tubes 2, as the part in contact with the tire, can roll. The use of this design can ensure that the tire evenly disperses force to both sides and can automatically correct the tire after misalignment occurs when the tire is disassembled or transported, ensuring that the tire will not slip.

[0035] Please refer to Figure 1 and Figure 4 Two rollers 3 are respectively installed on the second sections la2 of the two longitudinal sections la. The axes of the two rollers 3 are on the same horizontal line. That is, when the transport vehicle is normally placed, the two rollers 3 are swung until the first ends of the two longitudinal sections la abut against the ground.

[0036] Please refer to Figure 1 and Figure 2 In some embodiments, a reinforcing strip 6 is fixed between the second sections la2 of the longitudinal sections la and the transverse section lb.

[0037] The reinforcing strip 6 forms a triangular structure between the longitudinal sections la and the transverse section lb, reinforcing the connection between the longitudinal sections la and the transverse section lb, ensuring that the U-shaped frame 1 is firm, and that the two longitudinal sections la are less likely to bend and deform outward after the tire is placed on the two rolling tubes 2.

[0038] Please refer to Figure 2 and Figure 3 In some embodiments, the rollers 3 are also installed on the reinforcing strips 6, that is, one roller 3 has two connection points on the U-shaped frame 1, one connection point on the longitudinal section la and the other connection point on the reinforcing strip 6. More specifically, a steel plate is installed on the flange of the roller 3 as a mounting plate 3a, ensuring that the roller 3 is stably connected to the U-shaped frame 1. The two connection points are provided on the mounting plate 3a, one of which is in the form of a sleeve that is sleeved into the longitudinal section la of the U-shaped frame 1, and the other of which is a hole position that is connected to the reinforcing strip 6 by a screw.

[0039] Please refer to Figure 1 The handrail frame 4 includes a first connecting rod 4a and a handrail section 4b. The first connecting rod 4a is inclined, with the lower end fixedly connected to the middle position of the transverse section lb and the upper end directed away from the U-shaped frame 1. That is, the first connecting rod 4a is inclined in the side view. The handrail section 4b is fixedly connected to the upper end of the first connecting rod 4a, that is, the handrail section 4b extends away from the U-shaped frame 1.

[0040] The support frame 5 comprises a stopper 5a and a second connecting rod 5b. The stopper 5a is located at the side of the first connecting rod 4a close to the U-shaped frame 1, and the second connecting rod 5b connects the stopper 5a and the first connecting rod 4a. The support part is used to cooperate with the two rolling tubes 2, so that the placed tire can be kept in an inclined state towards the stopper 5a.

[0041] That is, after the tire is placed on the two rolling tubes 2, a force is applied downward on the handrail part 4b, and the two rolling tubes 2 and the tire are lifted upward with the rolling wheel 3 as a fulcrum. The tire is inclined upward to the stopper 5a, and finally is stopped by the stopper 5a and kept in an inclined state.

[0042] Please refer to Figure 1 and Figure 3 In some embodiments, the stopper 5a is arc-shaped, and the curved notch is towards the handrail frame 4. Compared with using a straight stopper 5a, the middle part of the arc-shaped stopper 5a can also enter the inner hole of the tire, and better limits the movement of the tire in the transverse direction, so that the tire is more stable.

[0043] Please refer to Figure 4 In some embodiments, the distance between the rolling tube 2 and the rolling wheel 3 in the longitudinal direction is less than the distance between the handrail part 4b and the rolling wheel 3 in the longitudinal direction. The two rolling tubes 2 and the tire can be lifted upward more easily.

[0044] Please refer to Figure 5 In some embodiments, the longitudinal part 1a can be telescopic in the transverse direction. More specifically, the transverse part 1b comprises a third segment 1b1 and two fourth segments 1b2; the two fourth segments 1b2 are telescopic rods, and the end parts of the rod bodies are fixedly connected to the two end faces of the third segment 1b1, and the shell and the second segment 1a2 are fixedly connected. The reinforcing strip 6 is arranged between the second segment 1a2 of the longitudinal part 1a and the fourth segment 1b2 of the transverse part 1b.

[0045] The first segment 1a1 can be telescopic in the longitudinal direction. More specifically, the first segment 1a1 is a telescopic rod, and the end part of the rod body is fixedly connected to the second segment 1a2.

[0046] The second connecting rod 5b can be telescopic in the longitudinal direction. More specifically, the second connecting rod 5b is a telescopic rod, and the end part of the rod body is fixedly connected to the stopper 5a, and the shell is fixedly connected to the first connecting rod 4a.

[0047] The first connecting rod 4a can be telescopic in the longitudinal direction. More specifically, the first connecting rod 4a is a telescopic rod, and the end part of the rod body is fixedly connected to the third segment 1b1 of the transverse part 1b.

[0048] The telescopic rod in the existing form can be selected, which can be used electrically, or the shell can be provided with a threaded sleeve at the end of the rod body to manually lock and fix the rod body. The telescopic rod in the drawing is a simple schematic.

[0049] When the tire size changes, the distance between the two rolling tubes 2 and the second connecting rod 5b are adjusted to adapt to the tire, making it more convenient for tire transportation. The length, height and width of the transport vehicle can also be changed according to the size of the tire and the comfort of the user.

[0050] Please refer to Figure 3 , Figure 4 and Figure 5 In some embodiments, the telescopic longitudinal portion 1a makes the width W of the transport vehicle 840-1140mm. The telescopic first section 1a1 makes the length L of the transport vehicle 1480-1870mm. The telescopic first connecting rod 4a makes the height H of the transport vehicle 750-980mm.
