The invention relates to the technical field of building construction, in particular to an underground pipe device which comprises a bottom plate, mounting seats are fixedly connected to the front and rear portions of the two sides of the top end of the bottom plate, rotating rollers are rotationally connected to the sides, close to each other, of the mounting seats on the same side, and gears are fixedly connected to the front sides of the peripheries of the rotating rollers; the gears are connected into the two sides of the chain in a meshed mode, a self-locking base is fixedly connected to the rear portion of the periphery of the rotating roller on one side, and a plurality of evenly-distributed limiting grooves are formed in the periphery of the self-locking base. The two ends of the steel wire rope are fixedly connected to the middle of the periphery of the movable roller, and the steel wire rope is evenly and spirally distributed; the self-locking device has the beneficial effects that the self-locking mechanism is arranged, the operation process can be completed by only one person, the labor cost is saved, the stability of a well pipe in the water well pipe descending process is guaranteed through the arrangement of the self-locking mechanism, and the situation that in the operation process, the well pipe is broken due to the fact that the well pipe slides downwards, and potential safety hazards possibly generated in the process are avoided.
本发明涉及建筑施工技术领域,具体为一种用于水井下管装置,包括:底板,所述底板顶端两侧前后部均固定连接有安装座,同侧安装座相互靠近一侧均转动连接有转动辊,转动辊外周前侧均固定连接有齿轮,齿轮分别啮合连接在链条两侧内部,一侧转动辊外周后部固定连接有自锁底座,自锁底座外周开设有多个均匀分布的限位槽;钢丝绳,所述钢丝绳两端分别固定连接在动辊外周中部且钢丝绳呈均匀螺旋分布;有益效果为:通过设置自锁机构,操作过程仅需一人即可完成,节省了人力成本,自锁机构的设置保障了水井下管过程中井管的稳定性,避免了操作过程中因井管下滑造成井管摔裂以及过程中可能产生的安全隐患。
