An anti-slip support device for the second lining trolley of an inclined shaft tunnel is proposed. The barbs 15 on the bottom surface 12 of the anti-slip base 10 can increase the friction between the support device and the ground. The setting of the anti-slip base 10 can also increase the contact area between the support device and the ground pit or the pre-buried steel bars on the ground, so that the force on the support device is more uniform and stable, the stability of the support for the second lining trolley is improved, and the risk of support instability is reduced. At the same time, the second end of the support member 30 is rotatably connected to the anti-slip base 10 through the hinge seat 20, which can cope with inclined shaft tunnels of various slopes.
