Arm rotating limiting and pressing device used for station tower inspection robot

The invention discloses an arm rotating limiting and pressing device used for a station tower inspection robot. The arm rotating limiting and pressing device comprises corner mechanisms, locking mechanisms and mechanical arms. Each corner mechanism comprises a rotating seat and a fixed seat rotationally connected to the rotating seat through a limiting device. Each locking mechanism is fixedly mounted on the corresponding fixed seat and comprises a follow-up device and a drive device driving the follow-up device to move through a transmission assembly. The follow-up devices are driven throughthe drive devices to move, so that corner limiting and locking to the station tower inspection robot are formed through cooperation of the follow-up devices and the limiting devices. The mechanical arms are fixedly mounted on the rotating seats. The arm rotating limiting and pressing device is simple in structure and stable and reliable in running. 本发明公开一种用于驻塔巡检机器人手臂转动限位压紧装置，包括：转角机构，所述转角机构包括转动座以及通过限位装置转动连接于所述转动座上的固定座；锁紧机构
