Self-adaptive guiding and positioning device and guiding and positioning system

The invention discloses a self-adaptive guiding and positioning device which comprises two guiding bases, two positioning bases and four guiding blocks located over the two guiding bases and the two positioning bases, and the four guiding blocks are arranged at the bottom of guided equipment. During mounting, the two guide blocks slide downwards along the surfaces of the two guide bases, so that the four guide blocks are connected with the two guide bases and the two positioning bases in a concave-convex fit manner; the self-adaptive guiding and positioning system comprises a plurality of self-adaptive guiding and positioning devices, and the plurality of self-adaptive guiding and positioning devices are arranged in at least one row at intervals. According to the self-adaptive guiding and positioning device and the guiding and positioning system, rapid guiding and positioning of equipment hoisting can be achieved in the state that observation is not convenient, the guiding range is enlarged, the hoisting prec
