[0012] The utility model will be further introduced below in combination with the drawings and specific embodiments.
[0013] Embodiment 1:
[0014] Overhead passenger anti-reverse device, such as Figs. 1-3As shown, it includes a mounting plate 1 arranged in a horizontal direction, which is mounted on a crossbeam. A vertical plate 2 is fixed to the rear of the lower end of the mounting plate 1. Two first fixing shafts 3 are vertically fixed to the lower right side of the front side of the vertical plate 2. One of the two first fixing shafts 3 is located to the lower left of the one on the right. A first rotating block 4 is rotatably connected to the first fixing shaft 3 on the right. The upper part of the first rotating block 4 is cuboid, the middle of the lower part of the first rotating block 4 is hollow, the lower part of the first rotating block 4 is an arc that bends to the right, and an arc-shaped groove that mates with the first fixing shaft 3 on the left side of the middle part of the first rotating block 4 is provided.
[0015] The spacing of the lower central hollow portion of the first rotating block 4 is smaller than the size of the cable grip of the aerial passenger vehicle. The steel wire rope passes through the lower central hollow portion of the first rotating block 4. When the cable grip of the aerial passenger vehicle passes from left to right, the first rotating block 4 can rotate counterclockwise, so the first rotating block 4 will not block the forward sliding of the steel wire rope. When the steel wire rope slides in the reverse direction, the first fixed shaft 3 on the left side restricts the first rotating block 4 from rotating clockwise. The first rotating block 4 will prevent the cable grip of the aerial passenger vehicle from passing through, thereby preventing the steel wire rope from sliding in the reverse direction, thus playing a role in preventing reverse rotation.
[0016] like Figs. 1-3 As shown, two second fixing shafts 7 are vertically fixed to the lower left part of the front side of the upright plate 2. The left one of the two second fixing shafts 7 is located to the upper left of the right one. A fourth rotating block 8 is rotatably connected to the left second fixing shaft 7. The upper part of the fourth rotating block 8 is semi-circular, and a protrusion is provided at the upper end of the fourth rotating block 8. The lower part of the fourth rotating block 8 is hollow in the middle and is an arc-shaped part that curves to the left. An arc-shaped groove that mates with the right second fixing shaft 7 is provided on the right side of the middle part of the fourth rotating block 8. The upright plate 2 is located between the first rotating block 4 and the... The second rotating block 5 and the third rotating block 6 are rotatably connected on the part between the second rotating blocks 5. The second rotating block 5 is located below the third rotating block 6. The upper part of the third rotating block 6 is rectangular, and the lower part of the third rotating block 6 is pointer-shaped. The second rotating block 5 is shaped like a "√". The left end of the second rotating block 5 and the upper end of the fourth rotating block 8 are locked at the lower left end of the third rotating block 6. During the counterclockwise rotation of the first rotating block 4, it can press the left end of the second rotating block 5, causing the second rotating block 5 to rotate and drive the third rotating block 6 to rotate counterclockwise, thus putting down the fourth rotating block 8.
[0017] Normally, the fourth rotating block 8 is in a horizontal position, when the first rotating block 4 is over-rotated to cause failure, the first rotating block 4 rotates counterclockwise, and the left end of the second rotating block 5 is pressed to make the second rotating block 5 rotate and drive the third rotating block 6 to rotate counterclockwise to put down the fourth rotating block 8, and the fourth rotating block 8 can prevent the cable carrier of the aerial passenger conveying device on the left side from passing, thereby preventing the normal sliding of the steel wire rope, thereby playing an insurance role, and the staff must reset the first rotating block 4 and the fourth rotating block 8 before the aerial passenger conveying device can pass normally.
[0018] The above merely describes the specific implementation of the present application, but the protection scope of the present application is not limited to this, any skilled person in the art can easily think of changes or replacements within the technical range disclosed by the present application, which should be covered in the protection scope of the present application, therefore, the protection scope of the present application should be subject to the protection scope of the claims.
