Detailed Description
In order that the utility model may be more readily understood, a more complete description of the utility model now follows, reference being had to the accompanying drawings, in which preferred embodiments of the utility model are shown; this invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein; rather, these embodiments are provided so that this disclosure will be thorough and complete.
It will be understood that when an element is referred to as being "secured to" another element, it can be directly on the other element or intervening elements may also be present; when an element is referred to as being "connected" to another element, it can be directly connected to the other element or intervening elements may also be present; the terms "vertical," "horizontal," "left," "right," and the like as used herein are for illustrative purposes only.
Unless defined otherwise, 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 invention belongs; the terminology used herein in the description of the utility model is for the purpose of describing particular embodiments only and is not intended to be limiting of the utility model; as used herein, the term "and/or" includes any and all combinations of one or more of the associated listed items.
Fig. 1 shows a schematic exploded view of a fall arrest safety device in accordance with an embodiment of the present invention, and for ease of description, the drawing shows only the structure relevant to the present invention.
As shown in fig. 1, an embodiment of the present invention provides a fall arrest safety device, including: the brake device comprises a brake cover plate 1, a brake disc 2, a brake pad block 3, an output shaft 4, a brake block 5, a brake box body 6, a brake block mounting shaft 7, an anti-falling box body 8, a flat key 9, an output gear 10, a return spring 11, a return spring mounting shaft 12 and a copper bush 13. 2 brake discs 2 are arranged and fixedly connected with the center of the output shaft 4; the brake discs 2 are arranged on two sides of the brake cushion block 3; the brake disc 2 is arranged between the brake cover plate 1 and the brake box body 6; the brake block 5 is arranged in a groove of the brake box body 6 through a brake block mounting shaft 7; the mounting shaft 12 of the return spring is fixedly connected with the brake box body 6; the return spring 11 is arranged in the return spring mounting shaft 12, and the lower end of the return spring 11 is arranged on the brake block 5; the brake cover plate 1 is fixedly connected with the brake box body 6 through bolts; the copper bush 13 is arranged in the anti-falling box body 8; a plurality of vortex grooves are arranged in the anti-falling box body 8; the output gear 10 is fixedly connected with the tail end of the output shaft 4 through a flat key 9, and the front end of the brake box body 6 is arranged in a copper sleeve 13.
It can be understood that when the output shaft 4 rotates, the brake disc 2 is driven to rotate, the brake disc 2 is in contact with the brake cover plate 1 and the brake box body 6, and due to the action of friction force, the brake cover plate 1 and the brake box body 2 are driven to move together, and at the moment, the brake block 5 performs centrifugal motion; when the rotating speed of the output shaft 4 reaches the braking speed, the front end of the brake block 5 is embedded into the vortex groove of the anti-falling box body 8, the brake box body 6 and the brake cover plate 1 are forced to stop rotating, at the moment, the output shaft 4 drives the brake disc 2 to continue rotating, the brake disc 2, the brake cover plate 1 and the brake box body 6 generate large braking torque, the speed of the output shaft 4 is forced to stop gradually, and the braking anti-falling effect is achieved.
The technical features of the embodiments described above may be arbitrarily combined, and for the sake of brevity, all possible combinations of the technical features in the embodiments described above are not described, but should be considered as being within the scope of the present specification as long as there is no contradiction between the combinations of the technical features.
