Abstract: Disclosed are a sliding groove type friction pendulum high-pier bridge seismic mitigation and an isolation bearing. The bearing includes an upper connecting steel plate, a lower connecting steel plate, and a frictional sliding component clamped between the upper connecting steel plate and the lower connecting steel plate. The frictional sliding component includes an upper bearing plate, a lower bearing plate, and a hyperbolic spheroid. The upper bearing plate and the lower bearing plate are disposed on corresponding connecting steel plates, and are mounted and cooperate by using a plurality of parallel protrusions and grooves. The hyperbolic spheroid is disposed between the upper bearing plate and the lower bearing plate. A plurality of hysteretic damping components, bearing positioning structures, butterfly-shaped spring components, and bearing limiting structures are disposed on opposite surfaces of the upper bearing plate and the lower bearing plate in a circumferential direction.

Abstract: A self-adaptive luggage transfer device and system. The self-adaptive luggage transfer device includes a base, a conveyor mechanism, a lifting mechanism and a self-adaptive extendable transfer mechanism. The lifting mechanism is arranged between the conveyor mechanism and the base and is configured to drive the conveyor mechanism to lift. The self-adaptive extendable transfer mechanism is obliquely arranged between the conveyor mechanism and the base and is in transmission connection with the lifting mechanism. Two ends of the self-adaptive extendable transfer mechanism are movably connected to an output end of the conveyor mechanism and the base, respectively. The conveyor mechanism is configured to drive an end of the self-adaptive extendable transfer mechanism connected to the conveyor mechanism to lift in a first direction, and the lifting mechanism is configured to drive at least one end of the self-adaptive extendable transfer mechanism to move in a second direction.
