The invention discloses an electric hydraulic locking device for a tail door of a dumper, and particularly relates to the technical field of locking devices, oil cylinder movable pins are fixed on the left side and the right side of the upper end of an oil cylinder fixing plate, the number of hydraulic oil cylinders is two, and the two hydraulic oil cylinders are rotatably connected to the upper ends of the two oil cylinder movable pins respectively. The oil pump is controlled to be opened and closed through the handle switch, so that the hydraulic lock hook can be pushed and pulled through the hydraulic oil cylinder, when the hydraulic oil cylinder pushes the hydraulic lock hook, the hydraulic lock hook rotates to be clamped with the limiting pin, and when the hydraulic oil cylinder pulls the hydraulic lock hook, the hydraulic lock hook rotates and is not clamped with the limiting pin any more, and locking is conducted through electric control and hydraulic drive. During operation, an operator only needs to operate a handle switch without getting off and manually opening the handle switch, the tail door is sealed tightly, and the problems that after a mechanical tail door locking device of an existing dumper is used for a period of time, the tail door is not sealed tightly, sewage overflows when scattered objects such as mud, gravel and the like are transported, and urban roads and air are seriously polluted are solved.
本发明公开了一种自卸车尾门电动液压锁紧装置,特别是涉及锁紧装置技术领域,油缸固定板上端左右两侧均固定有油缸活动销,液压油缸有两台,两台液压油缸分别转动连接在两根油缸活动销上端。通过手柄开关控制油泵启闭,这样可以利用液压油缸推拉液压锁钩,液压油缸推动液压锁钩的时候,液压锁钩转动与限位销卡接,而液压油缸拉动液压锁钩的时候,液压锁钩转动不再与限位销卡接,这样通过电动控制、液压驱动进行锁紧,操作人员在操作时只需操作手柄开关,不需要下车手动打开,尾门密封严实,解决了目前自卸车的机械式尾门锁紧装置,使用一段时间后,尾门密封不严实,运输泥浆沙石等流散物体时污水外溢,严重污染城市道路及空气的问题。
