The invention provides a device preventing a door stop from being opened. The device comprises the door stop, a bolt, a chain and a door nose part. The door stop comprises a first door stop stand column, a second door stop stand column and a door stop beam. The first end of the door stop beam is connected with the first door stop stand column in a rotatable mode. The second end of the door stop beam is connected with the second door stop stand column in a clamping mode. A through hole is formed in the second end of the door stop beam. The bolt penetrates the through hole. The door nose part is arranged on the second door stop stand column. The door nose part is connected with the bolt through the chain. By means of the device preventing the door stop from being opened, automatic opening of the door stop is avoided, and therefore the underground safety of inclined shafts is ensured.
