Description

Technical Field

[0001] The utility model mainly relates to the technical field of elevator brake wheels, in particular to a shock-absorbing elevator brake wheel. Background Art

[0002] When the elevator stops lifting, the traction motor loses power, and the coil in the brake electromagnet also loses power at the same time. The magnetic force in the electromagnet core quickly disappears, and the iron core is reset through the brake arm under the action of the brake spring, so that the brake shoe holds the brake wheel and the elevator stops working. This is the principle of elevator braking.

[0003] When the brake shoe holds the brake wheel, the brake wheel is suddenly braked by external force, which will cause vibration, which will not only shorten the service life of the brake wheel, but also affect the safety of elevator braking. Utility Model Content

[0018] To facilitate the understanding of the present invention, the present invention will be described more comprehensively below with reference to the relevant drawings. Several embodiments of the present invention are given in the drawings. However, the present invention can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the disclosure of the present invention more thorough and comprehensive.

[0019] In the description of the present invention, it should be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "page", "bottom", "inside", "outside", "clockwise", "counterclockwise" and the like indicating directions or positional relationships are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore should not be understood as a limitation on the present invention.

[0020] In addition, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying 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 one or more of the features. In the description of the present utility model, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.

[0021] In the present invention, unless otherwise clearly specified and limited, the terms "installed", "connected", "connected", "fixed", "provided with", etc. should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances. Example

[0022] See attached Figure 1-2 A shock-absorbing elevator brake wheel comprises an inner wheel 1 and an outer wheel 2, a slider 3 is fixedly mounted on the outer side of the inner wheel 1, an arc-shaped groove 301 is provided on the outer side of the slider 3, and the slider 3 is slidably connected with a slide groove 201 provided on the inner side of the outer wheel 2;

[0023] An embedded groove 202 is provided inside the outer wheel 2 , and a shock absorber 4 is installed in the embedded groove 202 . The telescopic end of the shock absorber 4 abuts against the inner wall of the arc-shaped groove 301 .

[0024] In this embodiment, the inner wheel 1 and the rotating shaft of the traction motor are connected by bolts, that is, the inner wheel 1 and the rotating shaft of the traction motor keep rotating synchronously. When the elevator stops lifting, the traction motor loses power, the rotation of the inner wheel 1 loses the driving source, and the brake shoe will hold the outer wheel 2. At this time, the slider 3 will slide in the slide groove 201, and the inner wheel 1 and the outer wheel 2 will achieve relative displacement. Through the cooperation of the telescopic end of the shock absorber 4 and the inner wall of the arc-shaped groove 301, it can be buffered, thereby reducing vibration. Not only does it have a long service life, but it also has high safety in elevator braking.

[0025] Springs 5 ​​are provided on the inner walls at both ends of the slide groove 201 , and the other ends of the two springs 5 ​​are fixedly connected to the two ends of the slider 3 respectively.

[0026] In this embodiment, during braking, the slider 3 slides in the slide groove 201 to squeeze the spring 5, and when braking stops, the elastic force of the spring 5 restores and pushes the slider 3 to slide in the slide groove 201 to its original position.

[0027] A keyway 101 is provided on the inner side of the inner wheel 1 for engaging with a flat key on the rotating shaft of the traction motor to prevent the inner wheel 1 and the rotating shaft of the traction motor from rotating relative to each other.

[0028] The surface of the outer wheel 2 is provided with through grooves 203 , and the through grooves 203 are in a plurality and arranged along the circumference of the center of the outer wheel 2 , so as to reduce the overall weight, save materials, and reduce the rotation resistance.
