Description

Technical Field

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

[0002] When rail-driven equipment is in motion, in order to achieve precise positioning and parking, the metal brake pads of the braking device are generally used to stop the driving equipment after friction between the driving device and the track. However, over time, the friction between the metal brake pads and the track will cause the track to wear and shorten the service life of the track. This will not only cause the brakes to lose their effect, but also due to the increased wear of the track, the driving equipment will also swing on the track, causing the driving equipment to move unsteadily. The replacement of the track is not only costly, but also has complicated replacement procedures and requires a long downtime, which affects the efficient progress of the operation. Utility Model Content

The airbag brake is connected to the moving trolley through a connecting frame. A telescopic airbag is provided on the airbag brake, the telescopic airbag faces the track surface, and the telescopic airbag is connected to the drive block.

[0005] The track is a hollow track, and the moving trolley is provided with traveling rollers and balancing rollers. Multiple traveling rollers are symmetrically arranged on both sides of the moving trolley, and multiple balancing rollers are arranged on the top of the moving trolley. The central axes of the traveling rollers and the balancing rollers are perpendicular to each other, and the traveling rollers and the balancing rollers are arranged in the track.

[0006] The driving block is a cylinder, and the cylinder is connected to the telescopic airbag.

[0007] The connecting frame includes a first connecting plate and a second connecting plate, the first connecting plate is connected to the moving vehicle, and the second connecting plate is connected to the airbag brake.

[0008] The telescopic airbag is a polyurethane structure.

[0009] The beneficial effects are: the structural design of the utility model is reasonable and ingenious, the airbag brake can greatly reduce the wear of the metal on the track, and the airbag is easy to replace, shortening the maintenance time and cost. At the same time, the traveling rollers and balancing rollers arranged on the moving trolley can ensure the stable operation of the moving trolley and avoid uneven wear on both sides caused by shaking. BRIEF DESCRIPTION OF THE DRAWINGS

[0010] The present invention will be described by way of examples with reference to the accompanying drawings, in which:

[0011] Figure 1 It is a three-dimensional structural diagram of the utility model;

[0012] Figure 2 It is a three-dimensional structural diagram of the mobile vehicle;

[0014] The present invention will now be described in further detail with reference to the accompanying drawings, which are simplified schematic diagrams that illustrate the basic structure of the present invention in a schematic manner.

[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.

[0017] like Figure 1-Figure 3 The airbag brake mechanism shown includes a track 1, to which a moving trolley 2 is connected. As shown, airbag brakes 4 are symmetrically arranged on both sides of the moving trolley 2. The airbag brake 4 is connected to the moving trolley 2 through a connecting frame 3. A telescopic airbag 42 is provided on the airbag brake 4. The telescopic airbag 42 faces the surface of the track 1. The telescopic airbag 42 is connected to the driving block 41. The telescopic airbag 42 is a polyurethane structure. Under the action of the driving block 41, the telescopic airbag 42 pops out and contacts the surface of the track 1, and the moving trolley 2 stops moving under the action of friction.

[0018] like Figure 2As shown, the track 1 is a hollow track, and the moving trolley 2 is provided with a traveling roller 6 and a balancing roller 5. A plurality of traveling rollers 6 are symmetrically arranged on both sides of the moving trolley 2, and a plurality of balancing rollers 5 are arranged on the top of the moving trolley 2. The central axes of the traveling rollers 6 and the balancing rollers 5 are perpendicular to each other. The traveling rollers 6 and the balancing rollers 5 are arranged in the track. When the moving trolley 2 is moving, the traveling rollers 6 drive the moving trolley 2 to move forward along the track 1 under the action of the transmission structure. The balancing rollers 5 on the top collide with the inner wall of the track 1 when the track is uneven, so as to avoid the moving trolley 2 from getting stuck. At the same time, the roller structure reduces the friction during the collision and reduces the impact on the drive.

[0019] like Figure 3 As shown, the driving block 41 is a cylinder connected to the telescopic airbag 42. The cylinder wraps around the edge of the telescopic airbag 42 and inflates the inner cavity of the telescopic airbag 42 to expand the telescopic airbag 42, providing a quick response. The connecting frame 3 includes a first connecting plate 31 and a second connecting plate 32. The first connecting plate 1 is connected to the moving vehicle 2, and the second connecting plate 32 is connected to the airbag brake 42.

[0020] The structural design of the utility model is reasonable and ingenious. The airbag brake can greatly reduce the wear of the metal on the track, and the airbag is easy to replace, shortening the maintenance time and cost. At the same time, the traveling rollers and balancing rollers arranged on the moving trolley can ensure the stable operation of the moving trolley and avoid uneven wear on both sides caused by shaking.

[0021] The above description is based on the present invention. Based on the above description, relevant personnel can make various changes and modifications without departing from the technical concept of this utility model. The technical scope of this utility model is not limited to the content of the specification. Its technical scope must be determined according to the scope of the claims.
