Novel elevator cab top maintenance safety protection device

Abstract

The invention discloses a novel elevator cab top maintenance safety protection device which structurally comprises a safety operating system, a safety shoe switch, a door fan, a portal sill, a touchpanel connecting rod, a safety touch panel, a door vane, four door pulleys, a door machine guide rail and two auxiliary rods. The two auxiliary rods are horizontally welded at the left end and the right end of the safety operating system, the door machine guide rail is fixedly welded at the top of the front end of the safety operating system and in reinforcement connection with the safety operating system through a bolt, and the four door pulleys are horizontally embedded into the front end of the door machine guide rail. According to the device, when an elevator needs to be maintained by a maintainer, an elevator traction machine stops working by the aid of the switch, the safety operating system stops running, a first lifting rod drives a braking arm, brakes clamp the auxiliary rods, sothat the safety operating system stays on the auxiliary rods, sliding risks of the elevator are prevented, personal safety of an on-site maintainer is protected, maintenance of the maintainer is facilitated, and trouble and labor are saved.

Description

technical field [0001] The invention is a novel elevator bridge top maintenance safety protection device, which belongs to the field of elevator bridge top maintenance safety protection devices. Background technique [0002] Elevator refers to the permanent transportation equipment that serves several specific floors in the building, and its car runs on at least two rigid rails that are perpendicular to the horizontal plane or at an inclination angle of less than 15° from the plumb line. There is also a step type, and the tread plate is installed on the crawler belt to run continuously, commonly known as an escalator or a moving walk. Fixed lifting equipment serving specified floors. A vertical elevator has a car running between at least two vertical or inclination angles of less than 15° rigid guide rails. The size and structure of the car are convenient for passengers to enter and exit or to load and unload goods. It is customary to use elevator as a general term for ve...
