Rail guided vehicle turnover claw mechanism

Abstract

The invention provides a rail guided vehicle turnover claw mechanism which comprises a turnover claw, a coupler, a bearing, a transmission shaft, a motor, a fixing plate, an installation base and a flexible connecting part arranged between the coupler and the transmission shaft. The coupler is provided with a first end and a second end; the installation base is fixedly arranged on the fixing plate; the motor is fixedly connected onto the installation base, and is connected to the first end of the coupler; the second end of the coupler is in flexible connection with the flexible connecting partthrough the transmission shaft; the turnover claw is fixedly connected to one end, far away from the coupler, of the transmission shaft; and the transmission shaft is connected onto the installationbase through the bearing. According to the rail guided vehicle turnover claw mechanism provided by the invention, the motor and the transmission shaft are in flexible connection, so that the occurrence of the phenomena of the damage of a motor shaft and the turnover jamming of the turnover claw caused when the turnover claw switches between a working position and an idle position can be avoided.

Description

technical field [0001] The invention relates to the field of shuttle car technology, in particular to a claw turning mechanism of a shuttle car. Background technique [0002] The shuttle car storage system is a kind of warehouse logistics automation system that adds high-precision guide rails to the traditional shelves, and the shuttle cars run smoothly on the high-precision rails. Multiple shuttle cars can work in the same lane at the same time, which greatly improves storage space utilization. The shuttle vehicle (RGV) is an intelligent handling equipment in the shuttle storage system, and it has gained more and more applications due to its intelligence and flexibility. The turning claw is the actuator of the shuttle vehicle (RGV). During material handling, the turning claw needs to be frequently switched between the working position and the idle position. [0003] At present, the turning claw mechanism adopts a structure mode composed of a combination of a motor, a tran...

AI Technical Summary

Problems solved by technology

[0003] At present, the turning claw mechanism adopts a structure mode composed of a combination of a motor, a transmission shaft and a turning claw or a combination of a motor, a shaft coupling, a transmission shaft and a turning claw (such as the Chinese patent document whose patent number is CN201520374236.1), However, due to the small eccentric range allowed by the coupling, it is difficult to assemble the turning claws; in addition, there are processing and assembly errors, which often cause the turning claws to turn over and get stuck or the motor shaft to switch between the working position and the idle position. damage phenomenon

[0004] In addition, the fault detection of the flipping claw mechanism currently on the market often uses one detection sensor at each end for detection (such as the Chinese patent document with the patent number CN201520372532.8), which increases the cost of installation and use; and the flipping claw The mechanism is directly installed on the fixed plate, which requires high assembly and is not convenient for installation, replacement, disassembly and maintenance
