[0002] During the overhaul of subway trains, the bogies need to be disassembled more thoroughly, and the wheelsets and axle boxes need to be separated from the bogies. When the wheelsets are transported on the track, they will carry the swing arm axle boxes at both ends together. Since the swing arm axle boxes are relatively long, the ball joint end of the swing arm axle box will come into contact with the ground without support, causing damage to the swing arm ball joint during transportation.

[0003] To address this phenomenon, some transport tools are generally designed for transport. In the prior art, a transport trolley is usually used for transport. A clamping component is provided on the trolley to clamp the rotating arm, and the trolley is provided with universal wheels for direction control. However, this method has the following disadvantages: the transport tool is too large to meet the portability requirement, and the stability is poor when the clamp is connected to the rotating arm because the support point is located at the center of the rotating arm.

[0040] In conjunction with the accompanying drawings, some embodiments of the present invention are described in detail below. In the absence of conflict, the following embodiments and features in the embodiments can be combined with each other.

[0041] like Figure 2 The figure shows the structure of the rotating arm that needs to be moved. Figure 2 In the invention, the two ends of the ball joint of the swing arm have a protruding part, and two sleeves are designed to fix the protruding part, so that the support point can be moved from the middle of the swing arm to the two ends. Specifically, a one-wheeled subway train wheel set axle box swing arm moving device, such as Figure 1 As shown, including:

[0042] One-wheel assembly;

[0043] A first connecting member, the bottom of which is connected to the one-wheel assembly;

[0044] The second connecting member, two in total, has a bottom portion connected to the top portion of the first connecting member;

[0045] The second connecting member includes a sleeve 1 and a guide column 2. The sleeve 1 is provided with a contoured hole that matches the two protrusions of the swing arm ball joint. The axis of the contoured hole is perpendicular to the axis of the guide column 2. The sleeve 1 is installed on the first connecting member through the guide column 2.

[0046] By designing two second connecting parts, when connected to the rotating arm, the supporting point is located on the rotating arm, so the stability is higher. With the convenience of the one-wheel assembly and the first connecting part for raising, the stable and convenient movement of the entire rotating arm can be achieved.

[0047] In almost all embodiments, the top end of the guide post 2 is inserted from the bottom of the sleeve 1 and connected to the top of the sleeve 1, so that a certain strength can be improved, and in most of the embodiments, the ratio of the distance between the guide post 2 and the two sides of the sleeve 1 should be between 1:1 and 1:3, so as to avoid the sleeve overturning caused by a large torque. In addition, in the scheme where the guide post 2 does not pass through the sleeve 1, the ratio of the distance between the guide post 2 and the two sides of the sleeve 1 should be between 1:1 and 1:2. By passing the guide post 2 through the sleeve 1, the strength can be improved.

[0048] Furthermore, in some embodiments, some screw holes may be provided on the sleeve so that some screws may be inserted to fix the ball joint.

[0049] In most embodiments, the first connector includes:

[0050] A mounting plate 3, used for connecting a second connecting member;

[0051] The raising bracket 4 is connected to the wheel assembly at the bottom and the mounting plate 3 at the top. The raising bracket 4 can be designed to raise the height. After raising the height, Figure 3 As shown, the entire rotating arm can be in a horizontal state, which makes it easier to maintain stability.

[0052] Generally, a hollow hole is provided in the heightening bracket 4, the axis of the hollow hole is perpendicular to the axis of the guide column 2 and the axis of the contoured hole, and:

[0053] The longitudinal section of the raising bracket 4 is U-shaped, wherein the longitudinal section is perpendicular to the axis of the hollow hole.

[0054] Furthermore, the projection area of ​​the hollow hole in the plane where the longitudinal section is located is greater than 70% of the projection area of ​​the raising bracket 4 in the plane where the longitudinal section is located.

[0055] Therefore, by providing a hollow hole and making the longitudinal section of the elevated bracket 4 U-shaped, and the projected area of ​​the hollow hole in the plane where the longitudinal section is located is larger than 70% of the projected area of ​​the elevated bracket 4 in the plane where the longitudinal section is located, on the one hand, sufficient space can be left for installing the balancing unit, and on the other hand, weight can be reduced, thereby improving the overall lightness of the device.

[0056] In some embodiments, two strip adjustment holes are provided on the mounting plate 3, and the long axis direction of the strip adjustment holes is parallel to the axis of the contoured hole. The two strip adjustment holes correspond to two guide columns 2 respectively, and the top of the guide column 2 passes through the strip adjustment hole and is adjusted to the target position along the long axis direction of the strip adjustment hole and then locked by a locking nut to fix the position. Of course, in other embodiments, it can also be fixed by welding to improve the overall structural rigidity, and loaded and unloaded by other methods, such as setting a socket at the bottom of the sleeve 1, first fixing the sleeve 1 on the ball joint, and then inserting the guide column 2 into the socket from bottom to top, and the top of the guide column 2 is supported by the upper inner surface of the sleeve 1.

[0057] In particular, in some embodiments, the first connecting member is further provided with an electric wheel, the central axis of the electric wheel is parallel to the axis of the contoured hole, so that the stability can be further improved by the rotation of the electric wheel. In such embodiments, a motor, a power supply, a flywheel and a transmission mechanism need to be configured, the power supply supplies power to the motor, and the output end of the motor is connected to the flywheel through the transmission mechanism, thereby driving the flywheel to rotate. In some of the embodiments, the speed of the flywheel can be adjusted by detecting the speed of the unicycle assembly. The slower the speed of the unicycle assembly, the faster the speed of the flywheel.

[0058] Additionally, in most embodiments, the wheel assembly includes:

[0059] Steering wheel 5;

[0060] Two wheel axle connecting members are respectively located on both sides of the directional wheel 5, and the axes of the two wheel axle connecting members are on the central axis of the directional wheel 5;

[0061] There are two connecting rods in total, which correspond to the two wheel axle connecting members respectively. One end of the connecting rod is connected to the corresponding wheel axle connecting member, and the other end is connected to the bottom of the first connecting member.

[0062] Generally, a hollow strip is provided on the connecting rod, which can reduce weight on the one hand and make it more beautiful on the other.

[0063] In some of the embodiments, the connecting rod first connecting member is connected by welding.

[0064] The ball joint end of the axle box swing arm has protruding semicircular structures on both sides, so that the ball joint will have an extra structure that can be used, and the swing arm will not fall to the ground due to structural instability during the transportation of the wheelset axle box. When the operator pushes it, the axle box will move forward with it. This tooling makes it easier for operators to transport the wheelset axle box and improves work efficiency.

[0065] The operation process is as follows: the operator puts two sleeves 1 on the protrusions on both sides of the ball joint end of the axle box swing arm, and then aligns the guide column 2 with the longitudinally arranged socket on the sleeve 1, and inserts the guide column 2 into the socket. Since the guide column 2, the mounting plate 3, the pad bracket 4, and the directional wheel 5 are welded together, the entire device forms a whole with the axle box, and can move with the wheelset.
