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 cylinder, a fixed seat is connected below the cylinder, a cylinder joint is connected above the cylinder, the upper end of the cylinder is connected to a rocker arm, a concave plate is provided at the end of the rocker arm, and a support is provided in the middle of the rocker arm.

[0005] The inner opening of the concave plate is provided with a nylon block.

[0006] 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.

[0017] 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.

[0018] like Figures 1 to 5 As shown, the utility model discloses a wheelset positioning device, which comprises a cylinder 1, a fixing seat 2 is connected below the cylinder, a cylinder joint 3 is connected above the cylinder, an external air source is connected, a rocker arm 4 is connected to the upper end of the cylinder, a concave plate 5 is provided at the end of the rocker arm, and a support 6 is provided in the middle of the rocker arm.

[0019] The inner opening of the concave plate is provided with a nylon block 7 to prevent damage to the wheel;

[0020] The working process of this utility model is as follows:

[0021] like Figure 5 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 embodiment, 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, and the cylinder pulls the right side of the swing rod down, and the concave plate on the left side of the swing rod rises to support the wheel rim of the wheel cake, so that it does not roll during work. When the assembly work is completed, the cylinder pushes the right side of the swing rod to rise, and the concave plate at the end of the swing rod drops and separates from the wheel rim, and the wheelset can roll freely on the track.

[0022] 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.
