Description

Technical Field

The utility model relates to the technical field of train vehicle detection, in particular to a detection mechanism and a wheel out-of-roundness detection device.

Background

Along with the demands and development of the railway transportation industry in China, the safety problem of the train is particularly important. In the long-time running process of the train, uneven abrasion can be generated on the tread of the wheels, so that the wheels are out of round, noise, vibration and the like can be generated on the train, and the stability of the train is affected. Therefore, the wheels need to be detected regularly, so that when the wear value of the wheel set reaches a certain value, the wheels are replaced in time, and catastrophic consequences such as derailment and the like are avoided.

For a long time, a manual detection method is mostly adopted for detecting the out-of-roundness of the wheel, namely, a detection device is required to be installed on the wheel and roll for one circle, the method is low in efficiency, and a maintainer is easy to fatigue in work, so that the method for dynamically detecting the out-of-roundness of the wheel on line is particularly critical.

When facing wheels with different rim heights, the lifting adjusting mechanism actively adjusts the height of the detection plate so as to prevent the detection plate from being impacted excessively. However, there is a problem that the detecting plate is passively pressed down when the wheel passes by in addition to actively lifting under the action of the lifting adjusting mechanism, and after that, the detecting plate needs to be restored to the original height in time after the wheel is driven off to ensure the normal operation of the next detection, but the existing device does not consider the problem.

Accordingly, improvements in the art are needed.

Detailed Description

For the purpose of making the objects, technical solutions and advantages of the embodiments of the present application more apparent, the technical solutions of the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present application, and it is apparent that the described embodiments are some embodiments of the present application, but not all embodiments of the present application. All other embodiments, which can be made by those skilled in the art based on the embodiments of the application without making any inventive effort, are intended to be within the scope of the application. In addition, as one of ordinary skill in the art can know, with technical development and new scenarios, the technical solution provided by the embodiment of the present application is also applicable to similar technical problems.

In the description of the present application, it is to be understood that all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs unless defined otherwise. Furthermore, any terminology used is for the purpose of describing particular embodiments only and is not intended to be limiting of the application.

In addition, numerous specific details are set forth in the following description in order to provide a better illustration of the application. It will be understood by those skilled in the art that the present application may be practiced without some of these specific details. In some instances, well known methods, procedures, components, and circuits have not been described in detail so as not to obscure the present application.

The technical scheme of the utility model is further described below by the specific embodiments with reference to the accompanying drawings.

Example 1

In view of the above-mentioned drawbacks of the conventional wheel out-of-roundness detection apparatus, the present inventors have actively studied and innovated based on the practical experience and expertise that are rich for many years in designing and manufacturing such products, and in combination with the application of the theory, so as to hope to create a technology capable of solving the drawbacks in the prior art, so that the wheel out-of-roundness detection apparatus has more practicability. After continuous research and design and repeated sample test and improvement, the utility model with practical value is finally created.

Referring to fig. 1-2, an embodiment of the present utility model provides a detection mechanism applied to a wheel out-of-roundness detection device, where the wheel out-of-roundness detection device includes a lifting adjustment mechanism, and the detection mechanism includes a detection plate 41, a mounting seat 42, and an elastic body 43; wherein,

The mounting seat 42 is connected with the lifting adjusting mechanism and provided with a groove 44;

at least part of the detection plate 41 is movably disposed in the recess 44;

The elastic body 43 is disposed in the recess 44 and is located between the recess 44 and the detection plate 41.

The wheel out-of-roundness detection device is mounted on the inner side of the track through the clamping seat, and the detection mechanism provided by the embodiment is arranged in the wheel out-of-roundness detection device.

When the height of the detection plate 41 needs to be adjusted according to the rim height of the wheel, the power component in the lifting adjusting mechanism outputs power in a rotating mode, and the power is transmitted to the rotating lifting component in the lifting adjusting mechanism, so that the rotating lifting component actively drives the detection plate 41 to lift under the action of the rotating force, and the height adjustment of the detection plate 41 is realized.

The elastic body 43 may be any common elastic body, such as a spring, a shrapnel, elastic rubber, etc., and is widely used in various mechanical devices. The main function of the elastomer 43 is to provide elastic support and elastic restoring force. As mentioned above, the detecting plate 41 is passively pressed down when the wheel passes by, in addition to actively lifting by the lifting adjustment mechanism, and after that, the detecting plate 41 needs to be restored to the original height in time after the wheel is driven off, and the mounting seat 42 and the elastic body 43 are introduced in this embodiment to achieve this purpose. Specifically, the mounting base 42 is connected with the lifting adjusting mechanism and provided with a groove 44; at least part of the detection plate 41 is movably disposed in the recess 44; the elastic body 43 is disposed in the recess 44 and is located between the recess 44 and the detection plate 41. When the wheel rim rolls the detecting plate 41, the detecting plate 41 is moved downward by the pressing force, the elastic body 43 is also pressed downward, the elastic body 43 is compressed and stores elastic potential energy until the elastic body 43 releases the stored elastic potential energy to restore its original shape when the pressing force is reduced or eliminated after the train passes, and the released elastic potential energy acts on the detecting plate 41 as an elastic restoring force to restore the detecting plate 41 to the original height.

It will be appreciated that the elasticity of the elastomer 43 depends on such factors as its material, geometry and dimensions. In general, the greater the elastic modulus of the elastomer 43, the more sensitive the elastomer 43 is to the response to downward pressure, that is, it can store more elastic potential energy.

In addition, at least two elastic bodies 43 are disposed in the groove 44, so as to ensure the stress balance of the detection plate 41.

Referring to fig. 3-4, in this embodiment, the detecting mechanism further includes a connecting plate 45;

The connecting plate 45 is connected with the lifting adjusting mechanism;

The mounting seat 42 is disposed on the connection plate 45.

Referring to fig. 4 again, in the present embodiment, the connection board 45 is provided with a mounting board 46 disposed perpendicular to the connection board 45;

the mounting block 42 is disposed on the mounting plate 46.

It should be noted that, in order to enhance the connection strength between the connection board 45 and the mounting base 42, the connection board 45 may be provided with a mounting board perpendicular to the connection board 45, the mounting base 42 is provided on the mounting board, and a connection part between the mounting board and the connection board 45 may be provided with a reinforcing rib.

Illustratively, the stiffener may be selected as a triangular stiffener.

It should be noted that, triangle-shaped is a stable structure, and it can effectively disperse strength when the atress reduces stress concentration degree to improve the bearing capacity and the shock resistance of strengthening rib. Triangular reinforcing ribs can also increase strength while reducing size compared to other shaped reinforcing ribs.

Referring to fig. 2 again, and referring to fig. 5 in combination, in the present embodiment, a chute 47 is formed on a wall of the recess 44, and a sliding strip 48 matched with the chute 47 is correspondingly disposed on an outer surface of the detection plate 41;

or, the groove wall of the groove 44 is provided with a sliding strip 48, and the outer surface of the detection plate 41 is correspondingly provided with a sliding groove 47 matched with the sliding strip 48.

In fig. 2 and 5, the chute 47 is formed on the wall of the recess 44, and the slide bar 48 is provided on the outer surface of the detection plate 41. The engagement of the slide groove 47 with the slide bar 48 ensures that the detection plate 41 and the mounting block 42 maintain a relatively stable sliding connection.

Referring to fig. 5 again, in the present embodiment, a plurality of positioning slots 410 are formed at the bottom of the groove 44;

the elastic bodies 43 are respectively provided in each of the positioning grooves 410.

It should be noted that, the positioning groove may be configured so that the elastic body 43 cannot easily displace, thereby avoiding the failure of the elastic body 43.

It will be appreciated that, to further limit the displacement of the elastic body 43, the detection plate 41 may be provided with a mounting groove having a depth deep enough to accommodate the elastic body 43 therein.

Referring to fig. 1-4 again, in this embodiment, the detecting mechanism further includes a limiting plate 49;

the two limiting plates 49 are arranged on the mounting seat 42 at intervals;

the detection plate 41 is located between the two limit plates 49.

The space between the two limiting plates 49 limits the displacement of the detection plate 41 in the horizontal direction when moving up and down, thereby enhancing the displacement stability of the detection plate 41.

Although the terms of the sensing plate, the mounting seat, the elastic body, the groove, the connecting plate and the like are used more in the utility model, the possibility of using other terms is not excluded. These terms are used merely for convenience in describing and explaining the nature of the utility model; they are to be interpreted as any additional limitation that is not inconsistent with the spirit of the present utility model.

The utility model provides a detection mechanism, which comprises a detection plate, a mounting seat and an elastic body, wherein the detection plate is provided with a plurality of mounting grooves; the mounting seat is connected with the lifting adjusting mechanism and provided with a groove; at least part of the detection plate is movably arranged in the groove; the elastic body is arranged in the groove and between the groove and the detection plate, when the wheel is pressed through the detection plate, the detection plate is passively pressed down, so that the elastic body is subjected to a downward pressure and stores elastic potential energy, and after the wheel is driven away, the elastic body can release the stored elastic potential energy to enable the detection plate to recover to the original height, the detection of the out-of-roundness of the next wheel is facilitated, and the detection plate has higher market popularization value.

Of course, as the rail vehicle passes, the sensing plate 41 will return to its original height, i.e. passively rise relative to the floor, since the sensing plate 41 is no longer crushed by the wheel rims.

It will be appreciated that the sensing plate 41 is actively raised and lowered relative to the support frame 1 by the lift adjustment mechanism 2 for the purpose of accommodating wheels of different rim heights, where the amount of movement of the sensing plate 41 is not the target data, so the displacement measurement module 3 does not measure the amount of movement of the sensing plate 41.
