Abstract
The utility model provides an opening protecting device of machine rooms of an escalator. According to the device, L-shaped angle plates are fixed on trusses, close to ports of machine room covering plates, on two sides of the upper machine room of the escalator and two sides of the lower machine room of the escalator, a contact switch is arranged at one end of each L-shaped angle plate, and the contact switches are connected with power sources of the machine rooms through relays; after the machine rooms are covered with the machine room covering plates, the contact switches are pressed, the power sources in the machine rooms can be turned on, and if the machine rooms are not covered with the machine room covering plates, the power sources in the machine rooms cannot be turned on. The opening protecting device of the machine rooms of the escalator has the advantages of being capable of guaranteeing absolute safety of the upper machine room and the lower machine room in a maintenance state, and avoiding safety accidents completely.
