Abstract

The invention belongs to the field of escalators, and specifically discloses a transitional transmission gear device applied to an escalator. A transitional transmission is provided in the power transmission mechanism; the transmission gear assembly is provided with a transmission gear and a positioning plate, and a plurality of limiters distributed in an annular array are arranged on the positioning plate. The limiter is provided with a cylinder, and the cylinder is A limit post is fixed; a limit plate is set on the mounting frame, and a plurality of limit holes A are opened on the limit plate in cooperation with the limit post; The limit members distributed in the array use the cylinder to drive the limit column to extend out of the limit hole B and penetrate into the limit hole A to complete the limit, so that the transmission gear and the positioning plate are fixed on the limit plate, and then have a self-locking structure to achieve uninterrupted power. Emergency stop self-locking.

Description

technical field [0001] The invention belongs to the field of the escalator field, and specifically discloses a transition transmission gear device applied to the escalator. Background technique [0002] Escalator or automatic pedestrian elevator, escalator, escalator, is a means of transportation that transports pedestrians by means of conveyor belts. In the transmission process, most of them are driven by gears and racks to complete the operation. [0003] Gear refers to a mechanical element that continuously meshes with gears on the rim to transmit motion and power; each convex part on the gear is used for meshing; generally speaking, these convex parts are arranged in a radial pattern; the teeth on the paired gears are mutually contact, resulting in continuous meshing operation of the gears. [0004] At present, various elevator accidents still exist. Among the factors that cause elevator safety hazards, there are manufacturing quality, installation, maintenance and use...
