Description
Technical field
The utility model relates to a kind of pipeline maintenance device.
Background technique
At present, in construction drainage pipeline construction, conventional inspection method is closed-water test, need to carry out shutoff to pipeline, existing shutoff mode many employings rubber pneumatic bag, rubber pneumatic bag needs the position of shutoff to carry out inflation at pipeline to realize seal for pipe joints, but in a practical situation, when floor standpipe is higher, rubber pneumatic bag cannot be resisted waterpower static pressure after inflation and cause rubber pneumatic bag alive de-, the phenomenons such as blast, or during the pressure testing of heavy caliber buried drain pipe, rubber pneumatic bag effectively cannot resist hydraulic pressure, effect is checked and accepted in impact test, in addition, rubber pneumatic bag material is softer, in storage, transport, easily damage in installation process.
Model utility content
The purpose of this utility model is to provide a kind of drainage pipe blocking device, solve the technical problem of pipe plugging poor effect in closed-water test; And solve blocking device and hold flimsy problem.
For achieving the above object, the utility model adopts following technological scheme:
A kind of drainage pipe blocking device, comprise the punch holder and die holder that are parallel to each other, in connection, fastening screw and the clamping bolt of die holder and on being clamped in, the rubber water-proof circle of the annular between the edge of die holder, the lower end of described fastening screw is fixedly connected with the center of die holder, upper end from the center of punch holder through and fastening by tightening nut, the outer side of the cross section of described rubber water-proof circle is arc, inner side edge is straight flange, base is straight flange, a groove is had in the middle part of top margin, wherein the base of rubber water-proof circle is overlapped on the edge of die holder, the inner side ledge of the top margin upper groove of rubber water-proof circle is against the rim under surface of punch holder, outside ledge is against the edge side surface of punch holder.
Edge 2 ~ the 5cm of the outer side distance punch holder of described rubber water-proof circle.
The material of described punch holder and die holder is steel or aluminum alloy.
The diameter of described punch holder is less than the diameter 0.5 ~ 1.5cm of die holder.
The upper surface of described punch holder is distributed with strengthening rib.
Described strengthening rib have at least twice, radially distribute from the center of punch holder to edge.
Compared with prior art the utility model has following characteristics and beneficial effect:
The utility model overcome traditional blocking device plugging effect poor, hold flimsy shortcoming, solve and ensure the technical problem of plugging effect.
Rubber water-proof circle is clamped between upper die holder by the utility model, shutoff in the duct, by the tightening up of tightening nut, make upper die holder extrude rubber water-proof circle, rubber water-proof circle tightly fit inner-walls of duct, realize the object of closed conduit, good airproof performance; During use, only need to tighten tightening nut, easy to use, efficiency is high; Upper die holder be connected with clamping bolt by the fastening screw of central position, uniform force, be tightly integrated with pipeline, therefore can bear larger pressure; Upper die holder adopts metal material to make, and material source is simple, sturdy and durable, not fragile, add working life and can reuse, and the metal material later stage can also reclaim, and improves economic benefit and is conducive to environmental protection; The utility model structure is simple, conserve space, be convenient to make and cost low, the upper die holder of different model can be made, to adapt to the line size of different size, in inspection pipeline leakproofness or carry out pipe plugging when carrying out pipeline maintenance, can plugging effect be significantly improved, ensure the efficiency of construction quality.
