The invention discloses a submersible sewage pump coupling and lifting device. The submersible sewage pump coupling and lifting device comprises a coupling seat, a coupling frame, a limiting seat, a guider and a submersible sewage pump, two positioning blocks are symmetrically arranged on the two sides of an inlet flange of the coupling seat, two positioning grooves are symmetrically formed in thetwo sides of a flange of the coupling frame, and two C-shaped guide grooves are symmetrically formed in the two sides of the upper portion of the flange of the coupling frame; the coupling frame is connected with an outlet flange of the submersible sewage pump through a bolt and is positioned through two taper pins which are symmetrically arranged on the two sides of the flange; and the couplingseat and the coupling frame are positioned and connected through a positioning inclined plane (1) of the positioning block and a positioning inclined plane (2) of the positioning groove and a flange inclined plane (1) of the coupling seat and a flange inclined plane (2) of the coupling frame, so that the coupling of the submersible sewage pump and the outlet pipeline is realized; the limiting seatis arranged below an inlet of the submersible sewage pump and is used for limiting the transverse displacement of the submersible sewage pump; and the guider is used for guiding steel wire ropes forhoisting and distributing acting force of the left steel wire rope and the right steel wire rope. The coupling and lifting device is applied to coupling and lifting of the large submersible sewage pump with the opening diameter 300 mm or above, coupling and lifting are convenient, sealing is reliable, maintenance is easy and convenient, the service life is long, and the maintenance cost is low.
本发明公开了一种潜污泵耦合与提升装置,包括耦合座、耦合架、限位座、导向器和潜污泵,耦合座的入口法兰两侧对称设置有2个定位块,耦合架的法兰两侧对称设置有2个定位槽,耦合架的法兰上部两侧对称设置有2个C形导向槽;耦合架与潜污泵的出口法兰通过螺栓连接,通过对称布置于法兰两侧的2个圆锥销进行定位;耦合座与耦合架通过定位块的定位斜面(一)与定位槽的定位斜面(二)以及耦合座的法兰斜面(一)与耦合架的法兰斜面(二)进行定位与连接,从而实现潜污泵与出口管路的耦合。限位座设于潜污泵入口下方,用于限制潜污泵的横向位移;导向器用于对起吊用的钢丝绳进行导向,同时分配左右两支钢丝绳的作用力。本发明应用于300mm口径以上的大型潜污泵的耦合与提升,耦合与提升方便,密封可靠,维护简便,寿命长,维护费用较低。
