The invention discloses a hydraulic automatic opening and closing movable top cover which is opened and closed oppositely in the longitudinal direction of a box body and is composed of a left movable top cover and a right movable top cover which are of the same structure and automatic opening and closing hydraulic control mechanisms which are arranged at the two longitudinal ends of the box body and operate synchronously. The control mechanism comprises a sliding rail, a sliding block, a hydraulic oil cylinder, a movable connecting rod, a connecting rod mounting base and a rotating shaft. The top cover adopts the hydraulic oil cylinder as power, sealing rubber strips are arranged on the periphery of the top cover charging opening, and sealing between the movable top cover and the fixed top cover can be achieved; sealing rubber strips are arranged on the opposite faces of the left top cover and the right top cover, and sealing between the left movable top cover and the right movable top cover can be achieved. The movable top cover device is automatically opened in a V shape, after opening, the left movable top cover and the right movable top cover can prevent goods from being poured towards the left side and the right side during loading, and the auxiliary loading function is achieved. The hydraulic automatic opening and closing movable top cover device adopts the hard movable top cover, so that the maintenance frequency in the long-term use process is reduced, and the maintenance cost is reduced.

    本发明公开了一种液压自动启闭活动顶盖,顶盖沿箱体纵向对开和关闭,由相同结构的左侧与右侧活动顶盖、和布置于箱体纵向两端的同步运行的自动启闭液压控制机构组成;控制机构包括滑轨、滑块、液压油缸、活动连接杆、连接杆安装座、转轴。本发明顶盖采用液压油缸作为动力,顶盖装料口四周设密封胶条,可实现与活动顶盖与固定顶盖的密封;左侧与右侧顶盖相对面设置密封胶条,可实现左右两侧活动顶盖之间的密封;活动顶盖装置呈V字型自动开启,开启后左右活动顶盖可防止货物在装载时向左右两侧倾洒,具有辅助装货功能;液压自动启闭活动顶盖装置采用硬质活动顶盖,减少了长期使用过程中的维修次数,降低了维修成本。
