Abstract

The invention discloses an elevator car roof with a rotary crawling ladder function. The car roof comprises an elevator car, and further comprises a car roof plate, a stepping motor, a rotating shaft,a rotating plate, an inclined frame, a fixed seat, an electric push rod I, a fixed shaft, a sliding groove, a folding frame assembly and an electric push rod II. According to the elevator car roof, at first, through an electric rotating plate mechanism, part of the car roof can be conveniently electrically opened, and people in the elevator car can conveniently escape from an opened power-on hole; then, due to the fact that the electric push rods and the folding frame assembly are adopted, the folding frame assembly can be conveniently stretched and unfolded, the crawling ladder function is achieved, contraction and folding can be conveniently carried out, the storage in an unused state is convenient, and the normal operation of an elevator is not interfered; and finally, due to the factthat the inclined frame has a certain inclination angle, the inclined frame can be conveniently unfolded and used in the elevator car and can also be upwards and obliquely lifted; and therfore, by means of the elevator car roof, workers can conveniently maintain the elevator car roof, and the people in the elevator car can conveniently escape.
