[0030] In the present application, the safety shaft pin 24 is arranged on the protection support seat 23 and can pass through the bearing seat 22, so as to limit the protection support seat 23 from being separated from the bearing seat 22. In normal times, the safety shaft pin 24 only connects the protection support seat 23 and the bearing seat 22 together, and is not subjected to the force between them. When the connecting bolt of the protection support seat 23 and the bearing seat 22 is broken, the safety shaft pin 24 plays a role in fixing the protection support seat 23 and the bearing seat 22, preventing other bolts that have not been broken from being subjected to a large force and easily broken, and causing the protection support seat 23 and the bearing seat 22 to be separated.

[0031] In the present application, the walking wheel assembly 3 is provided with an oil leakage prevention mechanism 6 that can prevent the lubricating oil in the walking wheel assembly 3 from leaking during the operation of the roller coaster.

[0032] In the present application, the oil leakage prevention mechanism 6 includes a first sleeve 61 and a second sleeve 62 that is engaged with the first sleeve 61. The first sleeve 61 is provided with an upward first flange 611 outside, and the second sleeve 62 is provided with a downward second flange 621 inside. The second sleeve 62 is pressed against the inner wall of the first flange 611, and the first sleeve 61 has a gap 63 between the inner side and the second flange 621.

[0033] In the present application, the first sleeve 61 includes a first bottom plate 612 and the first flange 611 outside the first bottom plate 612, and the lower surface of the first bottom plate 612 is inclined upward from outside to inside. The second sleeve 62 includes a second bottom plate 622 and the first flange 611 outside the second bottom plate 622.

[0034] In the present application, the walking wheel assembly 3 includes a walking wheel swing frame 31 arranged on the wheel frame 1, a walking wheel shaft 32 arranged on the walking wheel swing frame 31, a walking wheel shaft sleeve 33 sleeved on the walking wheel shaft 32, a walking wheel bearing 34 sleeved on the walking wheel shaft sleeve 33, and a walking wheel 35 arranged on the walking wheel bearing 34. The walking wheel 35 is provided with an oil cup 8, and the walking wheel 35 is provided with an oil supply channel 36 that communicates the oil cup 8 with the walking wheel bearing 34.

[0035] In the application, the limiting boss 331 is arranged on the walking wheel shaft sleeve 33, the second sleeve 62 is pressed on the walking wheel shaft bearing 34 through the limiting boss 331, so that the upper surface of the second bottom plate 622 is against the bottom surface of the limiting boss 331, the outer side of the second flange 621 is against the outer side surface of the walking wheel shaft sleeve 33, and the bottom end of the second flange 621 is against the end surface of the walking wheel shaft bearing 34; at the same time, the second sleeve 62 presses the first sleeve 61 on the limiting groove 351, so that the lower surface of the first bottom plate 612 is against the bottom surface of the limiting groove 351, and the outer side of the first flange 611 is against the side wall of the limiting groove 351.

[0036] The oil leakage prevention mechanism 6 is pressed between the walking wheel shaft sleeve 33 and the walking wheel 35, so as to seal the walking wheel bearing 34 and prevent the lubricating oil from leaking. At the same time, during the operation of the roller coaster, the lubricating oil flows along the walking wheel bearing 34 in the circumferential direction and continuously deviates outward due to the centrifugal force. At this time, the inner side of the walking wheel bearing 34 is sealed by the mutual pressing of the walking wheel shaft sleeve 33 and the second sleeve 62, and the outer side of the walking wheel bearing 34 is sealed by the pressing of the walking wheel 35 and the first sleeve 61. When the lubricating oil reaches the first bottom plate 612, it can only flow into the storage cavity 64 formed by the mutual cooperation of the first sleeve 61 and the second sleeve 62 through the gap 63 between the first sleeve 61 and the second sleeve 62. The lower surface of the first bottom plate 612 is inclined from the outside to the inside and upward, so as to guide the lubricating oil to flow along the first bottom plate 612 and then enter the storage cavity 64. After the roller coaster stops running, the lubricating oil remaining in the storage cavity 64 flows back to the walking wheel bearing 34.
