Problems solved by technology

In addition, mechanical failures often occur during mechanical operation, and the failures are sudden. Due to the large mass and high speed of the storage and transportation device and its cargo, it has a large moment of inertia, and it is impossible to stop the movement instantaneously.
If the power unit motor or reducer fails, the chain transmission unit is not power isolated, and the inertial load will inevitably drag the power unit back, resulting in further failures

Embodiment Construction

[0027] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0028] The implementation of the present invention will be described in detail below in conjunction with specific embodiments.

[0029] The chained storage and transportation device with fault-tolerant function of the present invention adopts a redundant fault-tolerant scheme of dual motors, so that when the main motor fails, the fault can be immediately isolated and the backup motor can be quickly used as the main driving force. In order to achieve this goal, it is necessary to add a clutch to the traditional motor-reducer system in terms of mechanism, and change the power unit to a series structu...

Abstract

The invention discloses a chain type storage and transportation device with a fault tolerance function. The chain type storage and transportation device comprises a support, an upper guide rail, a lower guide rail, a main motor and a backup motor, one end of the main motor is connected with the upper guide rail through a first transmission device, and one end of the backup motor is connected with the upper guide rail through a third transmission device. A second transmission device and a fourth transmission device are arranged on the lower guide rail, a plurality of object supporting bins are arranged between the upper guide rail and the lower guide rail, and the multiple object supporting bins can be driven by the four transmission devices to circularly operate along the upper guide rail and the lower guide rail; and a first clutch can achieve power transmission from the main motor to the first transmission device and can isolate power transmission from the first transmission device to the main motor, and a second clutch can achieve power transmission from the backup motor to the third transmission device and can isolate power transmission from the third transmission device to the backup motor. A redundant backup power system comprises the main motor and the backup motor, and the reliability and fault tolerance of the storage and transportation device can be improved.

Description

technical field [0001] The invention belongs to the technical field of storage and transportation, and in particular relates to a chain storage and transportation device with a fault-tolerant function. Background technique [0002] In the machinery industry, safety and convenience need to be considered in the process of transporting and selecting certain columnar objects with a large aspect ratio, and storage and transportation devices are often used to fix and protect the columnar objects. Based on the actual situation of the large mass of the column, the fixed shape of the load, the modularization of the storage and transportation device, and the compact installation space, a modular chain-type rotary storage and transportation device will be used to achieve storage and transportation. The device adopts the motor as the power source, reduces the speed and increases the force through the reducer, carries and transmits the power with the large-pitch chain, and drives the car...
