Waterproof lift shaft safety door

Abstract

The invention provides a waterproof lift shaft safety door. The waterproof lift shaft safety door is suitable for a lift shaft of a steel structure and is in an outdoor state, the normal closed state between the lift shaft safety door and the shaft of the steel structure can be guaranteed, external water cannot enter the lift shaft through the shaft safety door, components in the lift shaft and functions of lift electric components are guaranteed to be normal, the normal service life of a lift is guaranteed, and the lift maintenance cost is lowered. The waterproof lift shaft safety door comprises a lift shaft wall, and a shaft safety door opening is formed in the corresponding portion of the lift shaft wall. The waterproof lift shaft safety door is characterized in that a door frame is fastened onto the lift shaft wall through expansion bolts, one side of a door plate is installed on the corresponding side of the door frame through pin hinge structures, a waterproof strip is arranged at the position, facing the end face of the door frame, of the inner end of the door plate, and the waterproof strip is tightly attached to the door frame in the state that the door plate and the door frame are closed.

Description

technical field [0001] The invention relates to the technical field of elevator safety, in particular to a waterproof elevator shaft safety door, which is used for elevator emergency rescue, and is especially suitable for steel structure elevator shafts. Background technique [0002] According to the national standard requirements of elevators, when the distance between landings is greater than 11 meters, it is necessary to set up a safety door for the hoistway, which is used for emergency rescue such as fire. Because the national standard has some special requirements for safety doors, door manufacturers do not understand the elevator industry and the elevator national standard, so there are no professional companies in the market for this kind of elevator shaft safety doors. At present, in most cases, the safety door of the hoistway is taken care of by the user. The elevator manufacturer configures a safety door lock and installs it on site. Due to the lack of understandi...

AI Technical Summary

Problems solved by technology

[0003] Especially when encountering an open-air steel structure shaft, the safety door of the shaft is in the open state. The existing safety door of the elevator shaft cannot be waterproof, causing water to enter the interior of the elevator shaft, which makes the components inside the elevator shaft rust and the function of the elevator electrical components. Extend the normal service life of the elevator and increase the cost of elevator maintenance
