[0029] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Without conflict, the embodiments in this application and the features in the embodiments can be combined with each other. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0030] Please refer to Figures 1-3 , the present invention discloses a vertical maintenance tool for locomotive wheels, which is used to carry wheels for maintenance operations such as cleaning, inspection, grinding, flaw detection, and measurement, and includes:

[0031] A carrier 1, the carrier 1 includes two sets of brackets 11 arranged in parallel and a cross bar connecting the two brackets 11, and an installation part with a width greater than that of the wheel is provided between the two sets of brackets 11;

[0032] A limiting device 2, the limiting device 2 is arranged on the top of the carrier 1 to limit the wheels in the installation part;

[0033] Support rollers 5, the number of the support rollers 5 is two and they are symmetrically distributed in the carrier 1. The support rollers 5 include load-bearing rollers 51 for carrying wheels and connecting bearings 52 arranged on both sides of the load-bearing rollers 51. Bearing support seats 53 are respectively arranged on the two sides of the connecting bearings 52 and are arranged on the two sets of brackets 11 through the bearing support seats 53. The support rollers 5 are used to carry the wheels and enable them to rotate flexibly for maintenance operations.

[0034] When the present application is in use, the wheel is lifted by a crane and a special lifting device, and the wheel is moved to the middle position of the upper part of the carrier frame 1, so that the wheel is aligned with the center of the carrier frame 1, and the crane is controlled to slowly lower the wheel, and the wheel is stabilized to prevent rotation during the falling process. During the lowering process, the first universal ball bearings 3 on both sides of the tooling play a certain guiding role. After the wheel and the two supporting rollers 5 are in contact, the limiting device 2 is used to limit the axial position of the wheel. After the wheel is placed in the placement part, the wheel can be operated by the supporting rollers to rotate arbitrarily, so as to facilitate the cleaning, inspection, grinding, testing and other operations of the wheel;

[0035] It should be noted that the load-bearing roller 51 is provided with a limiting groove corresponding to the wheel for adapting thereto. Since the special shape of the load-bearing roller 51 coincides with the tread shape of the wheel, the load-bearing roller 51 can not only play a supporting role but also limit the axial movement of the wheel to a certain extent, thereby reducing the operational risk caused by the wheel movement during operation.

[0036] It is easy to imagine that the two groups of brackets 11 are welded from a plurality of square steel pipes, the two side edges and the bottom of the two groups of brackets 11 are fixedly connected by welding through cross bars 13, and no cross bars 13 are set on the tops of the two groups of brackets 11.

[0037] It should be further explained that a V-shaped detection groove 12 is provided in the center of the top of the two groups of brackets 11. The V-shaped detection groove 12 is composed of two groups of inclined square tubes arranged relatively obliquely. The missing part formed by the V-shaped detection groove 12 is used to facilitate the operator to clean, grind and measure the wheel when the wheel is installed.

[0038] In the present application, a calibration base 4 is provided at the bottom of the carrier frame 1, and the calibration base 4 is provided at the bottom of the V-shaped detection groove 12. In the present application, when the overhead crane lifts the wheel, the calibration base 4 can be used as a reference when placing the wheel. The operator can align the wheel with the calibration base 4 and then lower the wheel.

[0039] In the present application, it is easy to think that the first universal ball bearings 3 are arranged on the opposite sides of the top of the two groups of brackets 11. The first universal ball bearings 3 are used to prevent the wheels from being scratched and stuck with the brackets 11. During the descent process, the first universal ball bearings 3 on both sides of the tooling play a certain guiding role.

[0040] It should be further explained that the limiting device 2 includes a mounting base 21 fixedly connected to the bracket 11, a connecting rod 22 disposed in the mounting base 21, a handle 24 drivingly connected to the connecting rod 22, and a second universal ball bearing 23 disposed at the end of the connecting rod 22;

[0041] The mounting base 21 includes a base 211 and a connecting ring 212 disposed on the base 211;

[0042] The connecting rod 22 includes a telescopic rod 221 penetrating the connecting ring 212, and a connecting shaft 223 fixedly arranged on the base 211, and a hinged rod 222 is hingedly connected to the connecting shaft 223 and the telescopic rod 221.

[0043] The handle 24 is fixedly connected to the hinge rod 222 on the connecting shaft 223;

[0044] During operation, the wheel seat hole is manually polished to apply axial force to the wheel. Given the large size of the wheel, there is a risk of the wheel overturning under the action of the axial force. At this time, the upper part of the wheel can be fixed with the limit device 2. Due to the special nature of the connecting rod 22, the wheel will be restricted from axial shaking after the handle 34 of the limit device 2 is pushed forward to the lowest position. Due to the special slider structure of the connecting rod 22 of the limit device 2, the wheel will not push open the limit device 2 under the action of the axial force, provided that the device is not damaged, thereby ensuring the safety of the operator.

[0045] Finally, it should be added that there are four groups of the limiting devices 2 , and the four groups of limiting devices 2 are symmetrically arranged in pairs on the top of the supporting frame 1 .

[0046] It should be noted that if the embodiments of the present invention involve directional indications (such as up, down, left, right, front, back...), the directional indications are only used to explain the relative position relationship, movement status, etc. between the components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.

[0047] In addition, if there are descriptions involving "first", "second", etc. in the embodiments of the utility model, the descriptions of "first", "second", etc. are only used for descriptive purposes and cannot be understood as indicating or suggesting their relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of the features. In addition, the technical solutions between the various embodiments can be combined with each other, but they must be based on the ability of ordinary technicians in the field to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by the utility model.

[0048] In addition, "plurality" means two or more.

[0049] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
