Description

Technical Field

[0001] The utility model relates to equipment machinery for rail transportation, in particular to a wheel pair positioning device. Background Art

[0002] It is reported that in order to facilitate the assembly of the axle box and the front and rear covers of the axle box on the wheelset, a wheelset lifting platform is generally used to lift the wheelset to a height suitable for workers to operate. The lifting platform is provided with tracks, and the wheelset is placed on the tracks. After the assembly is completed, it is convenient to roll the wheelset off the platform and enter the next process. However, during the assembly process, due to the force applied, it is difficult to ensure that the wheelset does not roll, and it may even roll off the platform and accidentally injure people. There are unsafe hazards that must be studied and resolved to prevent them from happening. Summary of the invention

[0003] In order to solve the existing problems, the utility model provides a wheelset positioning device, which has a scientific and reasonable structure and can keep the wheelset positioned when various assemblies are completed on the wheelset, thereby ensuring work safety.

[0004] In order to achieve the above purpose, the technical solution of the utility model is a wheelset positioning device, which is characterized in that: it has a concave stopper, a cylinder is arranged under the stopper, a piston rod is arranged in the middle of the cylinder, guide columns are symmetrically arranged on both sides, and a mounting plate is arranged on one side of the cylinder jacket.

[0005] The beneficial effects of the utility model are that it has a scientific and reasonable structure, and when various parts are assembled on the wheelset, the wheelset can be positioned immovably, thereby ensuring safety and reliable operation; the utility model fills the market gap and meets customer needs.

[0016] The following describes embodiments of the present invention in conjunction with the accompanying drawings. It should be understood that the embodiments described herein are only used to illustrate and explain the present invention, and are not used to limit the present invention.

[0017] like Figures 1 to 6 As shown, the utility model discloses a wheelset positioning device, which has a concave stopper 1, a cylinder 2 is arranged under the stopper, a piston rod 3 is arranged in the middle of the cylinder, guide pillars 4 are symmetrically arranged on both sides, and a mounting plate 5 is arranged on one side of the cylinder jacket.

[0018] The working process of this utility model is as follows:

[0019] like Figure 4-6 As shown, the utility model is arranged in pairs on the platforms inside the two tracks. A wheelset lifting platform can be provided with multiple pairs of the utility model, which is convenient for multiple people to operate multiple wheelsets at the same time. In this figure, four sets are provided. When the wheelset rolls into the designated position of the lifting platform, a sensor is provided at the parking place of the wheelset, the cylinder rises, and the concave stopper holds the wheel rim to prevent it from rolling during operation. When the assembly work is completed, the cylinder descends, and the concave stopper is separated from the wheel rim to prevent interference with the wheelset, so that it can roll freely on the track.

[0020] The above is only one of the embodiments of the present invention and is not intended to limit the present invention. Although the present invention is described in detail with reference to the above embodiments, those skilled in the art can still modify the technical solutions described in the above embodiments or replace some of the technical features therein by equivalents. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.

Claims

1. A wheelset positioning device, characterized by: It has a concave stopper, under which a cylinder is arranged, a piston rod is arranged in the middle of the cylinder, guide pillars are symmetrically arranged on both sides, and a mounting plate is arranged on one side of the cylinder jacket.
