The invention relates to a hydraulic engineering pipeline maintenance device. The problems that in the prior art, when a pipeline is replaced, during manual pipe supporting, alignment is not easy, thepipeline is not stable enough, and working efficiency is low are effectively solved. According to the technical scheme for solution, the device comprises two supporting cross beams, positioning crossbeams are connected to the lower ends of the two supporting cross beams in an up-down sliding manner, positioning hydraulic cylinders are fixedly connected to the two ends of each of the two positioning cross beams, the two positioning hydraulic cylinders on each positioning cross beam are synchronously controlled by a positioning hydraulic pump fixedly connected to the corresponding positioningcross beam, and the upper ends of the two positioning cross beams are fixedly connected with stop arms penetrating through the corresponding supporting cross beams. The device is simple in structure and convenient to operate, left-right alignment of the pipeline is achieved through the positioning cross beams, the stop arms, a bearing platform and a sleeper, up-down alignment of the pipeline is achieved through an infrared transmitter and an infrared receiver, and therefore alignment of a replacement pipe and an original pipeline is guaranteed, operation is convenient, and practicability is high.
本发明涉及水利工程管道维修装置,有效的解决了在先技术中管道更换时人工扶管不易对正、不够稳定、工作效率低的问题;其解决的技术方案是包括两个支撑横梁,两个支撑横梁下端均上下滑动连接有定位横梁,两个定位横梁两端均固定连接有定位液压缸,每个定位横梁上的两个定位液压缸均受固定连接在相应定位横梁上的定位液压泵同步控制,两个定位横梁上端均固定连接有穿过相应支撑横梁的档臂;本发明结构简洁,便于操作,通过定位横梁、档臂、承载平台和枕木实现对管道左右的对正,通过红外发射器和红外接收器实现对管道的上下对正,从而保证了替换管和原管道的对正,便于操作,实用性强。
