The invention provides a dumper rear door locking device which comprises two locking plates which are oppositely arranged left and right and hinged to the bottom of a carriage, the two locking plates are connected through a hydraulic cylinder, and a roller is arranged at the end of each locking plate; a limiting block is arranged on the outer side of each locking plate, and each limiting block is provided with an abutting face which is obliquely arranged and faces the corresponding locking plate; the locking device further comprises a locking block arranged at the bottom of the carriage rear door, the locking block comprises two opposite slopes, and the slopes are used for abutting against the idler wheels. The locking device has the beneficial effects that through cooperation of the locking plate and the limiting block, opening and closing of the locking device can be achieved only through one hydraulic cylinder, and the locking device is simple in overall structure, low in cost, convenient to use and maintain and capable of being widely applied to various types of dump trucks. Meanwhile, the locking effect of the rear door of the dumper is improved, when the water content of cargo loaded in the compartment is high, the rear door of the compartment can still be effectively locked, and the problems of liquid dropping and liquid leakage caused by improper locking are avoided.
本发明提供了一种自卸车后门锁紧装置,包括左右相对设置且铰接在车厢底部的两个锁板,两个锁板之间通过液压缸相连接,每个锁板的端部设有滚轮;在每个锁板的外侧设有限位块,所述限位块具有倾斜设置且朝向所述锁板的抵靠面;还包括设置在车厢后门底部的锁紧块,所述锁紧块包括两个相对设置的斜面,所述斜面用于与滚轮相抵接。本发明的有益之处在于,通过锁板和限位块的配合,可以只采用一个液压缸来实现锁紧装置的开闭,整体结构简单,成本低,使用维护方便,可广泛应用于各类型自卸车。同时提升了自卸车后门的锁紧效果,当车厢内部载货含水量较高时,仍可有效锁紧车厢后门,避免发生因锁紧不到位而产生的滴液、漏液问题。
