摘要： The present invention provides a safety protection apparatus of a boarding bridge walking mechanism, the safety protection apparatus includes an inner retainer mechanism, an outer retainer mechanism, a connecting mechanism and an induction and control mechanism. The inner retainer mechanism includes an inner bracket and a first universal wheel. The inner bracket surrounds the boarding bridge walking mechanism and is hinged with the boarding bridge walking mechanism. The first universal wheel is disposed at one side of the inner bracket and supports the inner bracket. The outer retainer mechanism includes an outer bracket. The outer bracket is disposed on the outer circumference of the inner bracket, and a lower end of the outer bracket is lower than a lower end of the inner bracket. The connecting mechanism includes a first connecting component. The first connecting component is connected between the inner bracket and the outer bracket, such that the inner bracket is hinged with the outer bracket. The induction and control mechanism includes an induction unit. When the boarding bridge walking mechanism is tilted, the boarding bridge walking mechanism rotates relative to the inner bracket, and the inner bracket does not follow the boarding bridge walking mechanism to rotate; when the outer bracket is squeezed, the outer bracket approaches the inner bracket, such that the induction unit is triggered.
