Description

Technical Field

[0001] The utility model relates to an air bag brake cylinder. Background Art

[0002] The brakes used on traditional tracks are generally metal brake pads. The metal brake pads are clamped to the track through a transmission structure to achieve the braking function. On the one hand, the metal brake pads cause greater wear on the track. When the track is severely worn, the braking effect of the metal brake pads will be greatly reduced, and the braking accuracy will also be greatly reduced. At the same time, the replacement cost of the metal brake pads is high, and the process is cumbersome, which affects the continuous progress of the operation. Utility Model Content

[0003] In order to overcome the above-mentioned deficiencies, the utility model provides an air bag brake cylinder, which has sensitive response, causes little wear to the rail and is convenient for maintenance.

[0004] To achieve this purpose, the structure adopted by the present invention is: an airbag brake cylinder, including a cylinder body, the top of the cylinder body is a groove structure, an airbag is arranged in the groove structure, the edge of the airbag is pressed into the cylinder body by a pressure plate, a bolt is set at the bottom of the cylinder body to connect with the pressure plate, an airway is set on the side of the cylinder body, and the airway is connected to the airbag.

[0005] The airbag is a polyurethane structure.

[0006] The airbag is an annular structure, an inward fold is provided at the bottom of the annular structure, the edge of the pressure plate presses the fold into the cylinder body, a friction plate is provided on the top of the annular structure, and the annular structure and the friction plate are connected to each other through a connecting ring with an S-shaped longitudinal section. The annular structure, fold, friction plate and connecting ring are integrally formed.

[0007] The surface of the friction plate is provided with one or more notches.

[0008] A plurality of connecting holes are arranged around the cylinder body.

[0009] Its beneficial effects are: the structural design of the utility model is reasonable and ingenious, and the retractability of the airbag is utilized. When braking is required, air is inflated in the cylinder to expand the airbag, and the airbag achieves the braking effect through friction with the track. The polyurethane structure used in the airbag causes little wear on the track, and the airbag is easy to replace, which can ensure braking accuracy and continuous operation.

[0015] In the description of the utility model, it should be noted that the terms "upper," "lower," "inner," "outer," "front end," "rear end," "both ends," "one end," "the other end," and the like, indicating positions or relationships, are based on the positions or relationships shown in the accompanying drawings and are intended solely to facilitate the description of the utility model and simplify the description. They do not indicate or imply that the devices or components referred to must have a specific orientation, be constructed, or operate in a specific orientation. Therefore, they should not be construed as limitations on the utility model. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0016] In the description of the utility model, it should be noted that, unless otherwise expressly specified or limited, the terms "installed," "provided with," "connected," etc., should be understood in a broad sense. For example, "connected" can mean 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 an indirect connection through an intermediate medium, or it can be internal communication between two components; a fixed connection can be welding or gluing. Those skilled in the art will understand the specific meanings of the above terms in this utility model based on specific circumstances.

The annular structure and the friction plate 21 are connected to each other through a connecting ring 23 with an S-shaped longitudinal section. When air is inflated into the airbag 2 through the airway 3, the airbag 2 expands to deform the connecting ring 23, causing the friction plate 21 to bulge out. The friction plate 21 and the track realize the braking function under the action of friction force. The annular structure, folded edge 24, friction plate 21 and connecting ring 23 are integrally formed.
