The damping balls 52 are linearly arrayed along the outer wall of the fixed shell 51. The inner wall of the fixed shell 51 is rotatably connected to the pulley 53 through the fixed shaft 54, and the outer wall of the fixed shaft 54 ​​is fixedly connected to the inner wall of the fixed shell 51. The inner wall of the top of the air cushion 1 is fixedly connected to the outer wall of the fixed shell 51 through the mounting groove 7, and the mounting groove 7 is opened in the wall of the air cushion 1. The inner wall of the air cushion 1 is fixedly connected to the air pipe 4, and the air pipe 4 is linearly arrayed along the outer wall of the air cushion 1.

[0020] The outer wall of the foam board 2 is fixedly connected to the soft pad 3, and the soft pad 3 is linearly arrayed along the outer wall of the foam board 2. The fixing mechanism 6 includes a cable 62. The cable 62 is provided in four groups, and the outer wall of each group of cables 62 is fixedly connected to a hook 63, and the hook 63 is arranged in a circular array along the central axis of the cable 62. The end of the cable 62 close to the hook 63 is fixedly connected to a suction cup 65, and the suction cup 65 is adsorbed on a fixed point to limit the position of the cable 62.

[0021] The end of the pull rope 62 away from the suction cup 65 is rotatably connected to the fixed seat 61, and a limiting groove 64 is provided in the wall of the hook 63. The outer wall of the fixed seat 61 is fixedly connected to the outer wall of the air cushion 1, and the outer wall of the hook 63 is fixedly connected to the connecting rod 66.

[0022] Working principle:

[0023] When in use, first place the transport device on the stairs, then pull out the air plug on the air pipe 4, and supply air to the air cushion 1 through an external air pump to expand the air cushion 1. After the air cushion 1 is expanded, the air plug can be slid back into the air pipe 4 to maintain the expanded shape of the air cushion 1. Two groups of foam boards 2 are provided on the air cushion 1. One group of foam boards 2 needs to be placed above the stairs, and the other group of foam boards 2 needs to be placed below the stairs, so that the goods can be transported from the stairs to the bottom of the stairs through the transport device.

[0024] When transporting goods, the soft pad 3 on the foam board 2 is used to reduce the pressure of the goods on the foam board 2, and the air cushion 1 is fixed with a slow-down mechanism 5 through the mounting groove 7. Therefore, when the goods pass through the slow-down mechanism 5, the pulley 53 on the fixed shaft 54 ​​is used to assist the sliding of the goods, and the damping ball 52 on the fixed shell 51 is used to slow down the descending speed of the goods.

[0025] There are fixing mechanisms 6 at the corners around the air cushion 1. Therefore, when installing the transport device, it is only necessary to rotate the cable 62 on the fixing seat 61 to the fixed point, and then align the suction cup 65 on the cable 62 with the fixed point, and make the suction cup 65 adsorbed on the fixed point, so that the position of the air cushion 1 can be fixed by the cable 62. When it is necessary to release the adsorption of the suction cup 65, it is only necessary to grab the claw 63 and pull the claw 63 away from the suction cup 65, and the suction cup 65 can be lifted up through the connecting rod 66, so that external air can enter the suction cup 65. When the suction cup 65 cannot be adsorbed on the fixed position, it is only necessary to pass the bolt through the limit slot 64 on the claw 63 and fix the bolt on the fixed point to fix the position of the cable 62.
