The invention discloses a braking and relieving state monitoring device for a hand brake. Comprising a travel switch and a driving pawl mechanism. The travel switch is used for picking up a brake or release state signal of the hand brake, and the pawl mechanism drives the travel switch according to the brake and release state of the hand brake and comprises an induction pawl; the sensing pawl is axially provided with a kidney-shaped long round hole and is hinged to the box body through a cylindrical pawl rotating shaft, and the kidney-shaped long round hole and the pawl rotating shaft are in rotating and sliding fit. A ratchet tongue meshed with a driving shaft ratchet wheel is arranged at the radial long-diameter outer end of a kidney-shaped long circular hole of the induction pawl, a trigger contact is arranged at the other end of the induction pawl in the radial long-diameter direction of the long circular hole, a spring is sleeved with the spring in the axial direction of the spring sleeving column, and the other end of the spring and a spring support arranged on the box body form a compression reset structure. The top end of the trigger contact is matched with the travel switch button and can be triggered. The monitoring device provided by the invention can provide braking and relieving state signals of each vehicle hand brake of a train for a locomotive, so that the running safety of the train is ensured, and the working efficiency is improved.
