CHAIN DRIVING APPARATUS OF TWO-WAY CIRCULATION CONVEYING SYSTEM

摘要

Present invention discloses a chain driving apparatus of a two-way circulation conveying system comprising a power device, a transmission system, a tension device (7) and a driving chain (11). The transmission system includes a driving chain wheel (3), a driven chain wheel (4), a reverse gear wheel (10), a driving chain wheel shaft 1 (12), a driving chain wheel shaft 2 (9), a driven chain wheel shaft 1 (5), a driven chain wheel shaft 2 (6) and a mounting base (8). The driving chain wheel shaft 1 (12), the driving chain wheel shaft 2 (9), the driven chain wheel shaft 1 (5) and the driven chain wheel shaft 2 (6) are each fixed and mounted on the mounting base (8). The driving chain wheel shaft 1 (12) is connected with the power device, and the driving chain wheel shaft 2 (9) is connected to the driving chain wheel shaft 1 (12) through a pair of the reverse gear wheels (10). The driving chain wheel shaft 1 (12) and the driving chain wheel shaft 2 (9) are each provided with a driving chain wheel (3), and the driven chain wheel shaft 1 (5) and the driven chain wheel shaft 2 (6) are each provided with a driven chain wheel (4). The driving chain wheel (11) is mounted in a meshed manner on the driving chain wheel (3) and the driven chain wheel (4) of the transmission system. And the tension device (7) is connected to the driven chain wheel (4). The present invention adopts a set of power device to realize the upward and downward movement of the step chain, conserves energy, and facilitate transportation over long distance, by means of using the reverse gear to make the chain wheels at two sides rotated reversely.
