[0033] The two sliding carts 4 can be slidably embedded in the sliding rails of the two column bodies 2 respectively; the two sides of the movable platform 10 are respectively connected to the two sliding carts 4, for example, fixed by fasteners, which is not specifically limited by the present invention; the two sliding carts 4 can slide in the sliding rails of the two column bodies 2 to drive the movable platform 10 to move up and down.

[0034] The traction rope 5 is respectively wound on the fixed pulley 6 and the two sliding vehicles 4, and the two ends of the traction rope 5 are respectively connected to the drum unit 3 and the fixing member 8. The fixed pulley 6 and the fixing member 8 can be fixed to the two column bodies 2 by fasteners. The driving unit 13 is connected to the drum unit 3, and is used to drive the drum unit 3 to rotate so as to retract the traction rope 5.

The traction rope 5 can be specifically a steel wire rope, which has high strength and improves safety. In order to improve safety, the number of traction ropes 5 can be two.

[0035] Specifically, when the drum unit 3 reels in the traction rope 5, it drives the movable platform 10 to move upward; when the drum unit 3 releases the traction rope 5, it drives the movable platform 10 to move downward.

[0036] In the embodiment of the present invention, the up-and-down moving device comprises a fixed platform 1, a movable platform 10, two columns 2, a fixed pulley 6, two sliding vehicles 4, a traction rope 5, a driving unit 13, a reel unit 3 and a fixing member 8; the two columns 2 are arranged on the fixed platform 1 at intervals, and the two sliding vehicles 4 can be slidably embedded in the slide rails of the two columns 2 respectively; the two sides of the movable platform 10 are respectively connected to the two sliding vehicles 4; the traction rope 5 is respectively wound on the fixed pulley 6 and the two sliding vehicles 4, and the two ends of the traction rope 5 are respectively connected to the reel unit 3 and the fixing member 8; the driving unit 13 is connected to the reel unit 3, and is used to drive the reel unit 3 to rotate so as to retract and release the traction rope 5. The present invention realizes the up-and-down movement of the movable platform 10 based on the combination of the driving unit 13, the reel unit 3, the fixed pulley 6, the sliding vehicle 4 and the traction rope 5. Compared with the existing electric cylinder method, it is smaller in size, occupies less area, and is easy to install in a limited space.

[0047] A pulley 44 is installed in the middle of the frame 41. The traction rope 5 is wound around the pulley 44. As the traction rope 5 is retracted and released, the sliding vehicle 4 is driven to move up and down. The pulley 44 acts as a movable pulley, which can effectively reduce the supporting load. In order to prevent the traction rope 5 from escaping from the pulley 44, a set of wire rope pressure wheels are installed on the side of each pulley 44 that contacts the wire rope.

[0048] Furthermore, the sliding vehicle 4 further includes an auxiliary limiting wheel 43 , and the auxiliary limiting wheel 43 is arranged on a side surface of the vehicle frame 41 .

The installation direction of the auxiliary limiting wheels 43 is perpendicular to the installation direction of the rollers 42.

[0050] In the embodiment of the present invention, by controlling the rotation of the reel unit 3, the sliding vehicle 4 drives the movable platform 10 to move up and down; the experiencer can wear VR glasses and stand in the movable platform 10 to have an immersive feeling through the game screen.
