Abstract

The invention discloses a bidirectional non-return gear box. A gear motor is fixed to a shell of the gear box; a transfer mechanism is arranged in the gear box; the transfer mechanism is connected with the gear motor through a chain; a chain tensioning mechanism is arranged outside the gear box; the transfer mechanism is provided with two transfer shafts, and the two transfer shafts are connectedthrough a two-way backstop; the gearbox is provided with an output shaft, synchronous belt wheels are arranged at the two ends of the output shaft, and the output shaft is in gear transmission with atransfer shaft; and the gear box is provided with a manual emergency rotating shaft, and the manual emergency rotating shaft is in gear transmission with the other transfer shaft. By arranging a poweroutput system with a non-return structure, when the output power fails to work suddenly, the problem that a lifting mechanism in transmission with the gear box falls suddenly is avoided. By arrangingthe two gear motors, when the motor for achieving power output breaks down, a structure capable of immediately completing backup power output is provided, to solve the problem that no power source exists.

Description

technical field [0001] The invention relates to the technical field of elevator manufacturing, in particular to a gear box capable of realizing bidirectional backstop protection. Background technique [0002] At present, the development prospects of my country's logistics industry are broad, especially in the past ten years of development, my country has become a logistics power. In logistics automation production, elevators are indispensable for lifting materials. In order to further improve production efficiency and production safety, production enterprises put forward higher and higher requirements for the safety of elevator handling. In the past, the safety performance of elevator handling was mostly worrying. At the same time, it was difficult to carry out timely maintenance after a failure occurred. Contents of the invention [0003] The purpose of the present invention is to provide a two-way backstop gearbox, which can ensure that the lifting structure connected t...
