Abstract

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.

Description

technical field [0001] The invention relates to coal mine safety technology, in particular to a device for preventing the opening of a door stop. Background technique [0002] In recent years, with the rapid increase of coal mining output, the main inclined shafts underground and the up-and-down hill transportation in the mining area are extremely frequent. The inclined shaft transportation is responsible for important tasks such as material transportation, installation, and demolition, and it is often time-consuming Tight, heavy task. With many inclined shafts underground and frequent transportation, the door stop of the inclined shaft plays a particularly important role in the whole operation process. facility. [0003] At present, the door stops of the inclined shaft installed underground are affected by the installation conditions, later use and management conditions, and some door stops have abnormal automatic opening and opening, which causes the vehicles in the road...
