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 slide seat is connected to the front of the cylinder, the slide seat is concave, a stopper is provided in the concave, and the stopper is connected to the cylinder piston rod.

[0005] The working surface of the stopper 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.

[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 4 As shown, the utility model discloses a wheelset positioning device, which has a cylinder 1, a slide seat 2 is connected to the front of the cylinder, the slide seat is concave, a stopper 3 is arranged in the concave, and the stopper is connected to the cylinder piston rod 4;

[0018] The working surface of the stopper is provided with a nylon block 5 to prevent damage to the wheel;

[0019] The working process of this utility model is as follows:

[0020] like Figure 4 As shown, the utility model is arranged in pairs on platforms inside two tracks. The utility model is arranged at both ends of a wheelset lifting platform to prevent the wheelset from rolling out of the lifting platform during the assembly of parts. Multiple people and multiple wheelsets can be operated simultaneously. When the wheelset rolls into the lifting platform, the cylinder pushes the block to extend, and the slide seat plays a guiding role. The block blocks the wheel rim position to prevent it from rolling out of the lifting platform during operation. When the assembly work is completed, the cylinder drives the block to retract into the concave slide seat without interfering with the free rolling of the wheelset on the track.

[0021] 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.
