The invention provides a skip bucket vertical shaft wellhead sealing maintenance platform. The skip bucket vertical shaft wellhead sealing maintenance platform comprises a main support, and further comprises two bottom sealing platforms, two middle sealing platforms and two top sealing platforms which are sequentially installed on the main support from bottom to top; and each bottom sealing platform comprises two bottom layer platform supports and two bottom layer sealing plates. According to the skip bucket vertical shaft wellhead sealing maintenance platform, a hydraulic oil cylinder can push a plurality of main platform sealing plates to oppositely move on a main platform track so that the four main platform sealing plates can be all pushed to the position above a wellhead, effective sealing protection is formed on the wellhead, foreign matters are prevented from entering the wellhead, an inner side sealing plate and an outer side sealing plate are moved to be close to a skip bucket, then positioning pins are used for fixing the inner side sealing plate and the outer side sealing plate so that a worker can stand on the inner side sealing plate and the outer side sealing plate to check and maintain the skip bucket, and the maintenance becomes simple and convenient.
本发明提供了一种箕斗竖井井口密封检修平台,包括主支架以及自下而上依次安装在主支架上的两个底部密封平台、两个中部密封平台、两个顶部密封平台,所述底部密封平台包括两个底层平台支架、两个底层密封板;本发明通过液压油缸可推动多个主平台密封板在主平台轨道进行对向移动,从而可将四块主平台密封板全部推动到井口的上方,对井口形成有效的封闭防护,保护井口内不会进入异物,通过移动内、外侧密封板靠近箕斗,再使用定位销将内、外侧密封板进行固定,工人即可站在内、外侧密封板上对箕斗进行检查维修,使得检修变得简单、方便。
