Detailed Description

The present invention will be further described in the following to make the technical means, the creation characteristics, the achievement of the purpose and the effect of the present invention easy to understand.

As shown in fig. 1 to 4, an annular Weiya system with a protection mechanism comprises a top hanging plate 1, wherein an annular groove 1a is fixedly formed in the top hanging plate, a travelling mechanism 2 is installed on the annular groove 1a, an electric hoist 3 is fixed at the bottom of the travelling mechanism 2, a hanging basket 5 is hooked on the electric hoist 3, and a braking mechanism 4 is arranged between the hanging basket 5 and the electric hoist 3. When in use, the travelling mechanism 2 moves along the annular groove 1a in an annular shape, and a hanging basket 5 drives a performer to perform various performances in the air.

The braking mechanism 4 comprises a mounting plate 41 fixed at the bottom of the electric hoist, rollers 42 which are abutted against the steel wire rope 6 and are symmetrically distributed on the steel wire rope 6 and are connected to the mounting plate 41, a centrifugal wheel member 43 connected with the rollers 42, a swinging rod 44 which is symmetrically distributed on the steel wire rope 6 and is hinged to the mounting plate 41 and turned outwards, a connecting rod 45 hinged to the swinging rod 44, a guide block 46 fixed on the mounting plate 41 and horizontally matched with the connecting rod 45 in a sliding mode, a compression spring 47 sleeved on the connecting rod 45, one end of which is fixed on the connecting rod 45, the other end of which is fixed on the guide block 46, a long rod 48 abutting against one end of the guide block 46 far away from the compression spring 47 and vertically inserted on the connecting rod 45, and a push rod 49 hinged on the mounting plate 41, one end of which is matched with the long rod 48 in a sliding mode, and the other end of which abuts against the centrifugal wheel member 43. When the device is used, when the steel wire rope 6 is broken, under the action of gravity of a performer, the movement speed of the steel wire rope 6 is instantaneously increased, the centrifugal wheel member 43 is driven to perform centrifugal movement, the push rod 49 is pushed to swing outwards, the long rod 48 is separated from the connecting rod 45 to be inserted, the connecting rod 45 rapidly drives the swing rods 44 to be close to the steel wire rope 6 and tightly prop against the steel wire rope 6 under the action of the compression spring 47, and the steel wire rope 6 can only be tightly blocked between the swing rods 44 due to the turnover mechanism of the swing rods 44, so that the performer is prevented from falling.

The centrifugal wheel member 43 comprises a disc 431 coaxially arranged with the roller 42, centrifugal blocks 432 hinged on the outer circular surface of the disc 431 and uniformly distributed circumferentially, and a small spring 433 with one end connected with the centrifugal blocks 432 and the other end connected with the disc 431. In use, the centrifugal block 432 is driven to perform centrifugal motion outwards only when the speed on the steel wire rope 6 is large enough by the limiting action of the small spring 433, so that the opening of the braking mechanism 4 is ensured.

The push rod 49 is in an inverted V shape, a long strip hole 49a is formed in one end, far away from the centrifugal wheel component, of the push rod 49, a sliding column 48a matched with the long strip hole 49a is arranged on the long rod 48. The hinge point of the push rod 49 and the mounting plate 41 is located near the elongated hole 49 a. In this way, the outward thrust generated by the centrifugal wheel member 43 acts on the push rod 49 to turn outwards, thereby activating the brake mechanism 4.

The travelling mechanism 2 comprises a mounting seat 21, travelling wheels 22 symmetrically connected to the mounting seat 21 and matched with the annular groove 1a, and a driving motor 23 connected with any travelling wheel 22 and fixed on the mounting seat 21. In use, the drive motor 23 drives the road wheel 22 to move in the annular groove 1 a.

The foregoing has shown and described the basic principles, principal features and advantages of the invention. It will be understood by those skilled in the art that the present invention is not limited to the embodiments described above, and that the above embodiments and descriptions are merely illustrative of the principles of the present invention, and various changes and modifications may be made without departing from the spirit and scope of the invention, which is defined in the appended claims.
