The invention relates to a 30-ton axle load side dumping type coal hopper car and a bottom door opening and closing mechanism thereof. The bottom door opening and closing mechanism comprises a top connection assembly, a rotating part, a transmission assembly and a linear driving assembly, wherein the top connection assembly is used for being hinged to a bottom door of the hopper car; the rotatingpart is used for being hinged to a bottom frame of the hopper car; the transmission assembly comprises a first crank throw, a connecting piece, a second crank throw and a lower crank throw which are sequentially hinged from top to bottom, the first crank throw is hinged to the rotating part, and the lower crank throw is hinged to the top connection assembly; and the output end of the linear driving assembly is hinged to the rotating part, so that when the linear driving assembly stretches out and draws back, the first crank throw can be driven to act. The hopper car comprises a side wall, a hopper ridge, a bottom frame, a bottom door covering between the side wall and the hopper ridge, and the bottom door opening and closing mechanism. By means of the technical scheme, the problem that inthe prior art, a bottom door opening and closing mechanism is poor in self-locking performance can be solved.

    本发明涉及提供一种30吨轴重侧卸式煤炭漏斗车及其底门开闭机构。该底门开闭机构,包括:顶接组件,用于铰接于漏斗车的底门;转动件,用于铰接于漏斗车的底架;传动组件,包括由上至下且依次铰接的第一曲拐、连接件、第二曲拐和下曲拐,其中,第一曲拐铰接于转动件,下曲拐铰接于顶接组件;以及线性驱动组件,线性驱动组件的输出端铰接于转动件,以当线性驱动组件伸缩时,能够带动第一曲拐动作。一种漏斗车,包括侧墙、漏斗脊背、底架、盖合于侧墙与漏斗脊背间的底门,漏斗车还包括如上述的底门开闭机构。通过上述技术方案,可以解决现有技术中底门开闭机构本身结构存在自锁性能较差的问题。
