Abstract
The utility model discloses a Z-shaped elevator backstop device, relates to the technical field of elevators, and aims to solve the problems that lubricating oil is wasted and the working environment is polluted due to the fact that lubricating oil is easy to throw out from the moving position of a pawl mechanism when a ratchet wheel rotates. A protective shell is arranged on the ratchet wheel, an oil injection opening is formed in the top of the protective shell, and a notch for the pawl mechanism to be inserted in is formed in the protective shell. A splash-proof plate for preventing lubricating oil from splashing is arranged on the top surface of the protective shell; the oil injection port is formed in the protective shell, lubricating oil can be conveniently injected into the protective shell, when the elevator body is started, the rotating shaft drives the ratchet wheel to rotate in the protective shell, lubricating liquid can be automatically adhered to the ratchet wheel for lubricating operation, frequent manual intervention is not needed, the maintenance cost is effectively reduced, and the good running state of the ratchet wheel is guaranteed; the service life of the ratchet is prolonged.
