The invention discloses an automatic manhole cover locking device and an intelligent powder and particle material transportation tank car, and relates to the technical field of powder and particle material transportation tank car equipment.The automatic manhole cover locking device comprises a rotating part rotationally arranged on a manhole cover, a rotation driving part used for driving the rotating part to rotate and a plurality of clamping parts; a clamping opening is formed in the clamping seat, the clamping part comprises a first connecting rod and a pin shaft which are hinged to each other, the end part of the first connecting rod is hinged to the rotating part, the pin shaft is arranged in the guide seat in a penetrating manner, the end part of the pin shaft extends into the clamping opening to be clamped when the rotating part rotates forwards, and the end part of the pin shaft is separated from the clamping opening when the rotating part rotates backwards; due to the fact that the clamping parts are all hinged to the rotating parts, when the rotating parts rotate, the rotating parts can be driven to rotate at the same time, the locking action is more synchronous, and the manhole cover can be locked easily; and only one rotating driving part is arranged, so that the structure is simpler, the operation is more convenient, and the equipment cost can be reduced.
本发明公开一种人孔盖自动锁紧装置及智能化粉粒物料运输罐车,涉及粉粒物料运输罐车设备技术领域,包括转动设置在人孔盖上的转动部、用于驱动转动部转动的转动驱动部及若干卡接部,人孔颈圈上固定有若干卡接座,卡接座上设置有卡接口,卡接部包括相铰接的第一连杆及销轴,第一连杆的端部铰接在转动部上,销轴穿设在导向座中,转动部正向转动时将销轴的端部伸入卡接口中卡紧,反转时,销轴的端部自卡接口中脱出;由于本发明中的卡接部均铰接在转动部上,当转动部转动时,能够驱动若干转动部同时转动,锁紧动作更加同步,有利于锁紧人孔盖;并且转动驱动部仅设置一个即可,结构更加简单,不仅更便于操作,还能降低设备成本。
