The invention discloses an elevator running acceleration detection and protection device. The elevator running acceleration detection and protection device comprises a guide rail arranged in a well, an elevator part system, a brake unit, a linkage adjusting rod, an adjusting weight and an action switch connected with an elevator electrical loop. The brake unit is installed on the elevator part system, and an operation gap is formed between the brake unit and the guide rail. The tail end of the linkage adjusting rod is rotatably installed on the elevator part system and forms a rotating fulcrum, the action switch is installed above the tail end of the linkage adjusting rod and can make contact with the linkage adjusting rod, the starting end of the linkage adjusting rod is connected with a follow-up rod, a connecting piece is installed below the brake unit, the elevator part system is provided with a fixing piece and corresponds to the connecting piece in position, and a pull rod is connected to one end of the follow-up rod. The elevator running acceleration detection and protection device has great advantages in the aspects of stability, accuracy, applicability and the like, can be generally used in new elevators and can further be used for additional protection of old elevators at the same time.
