Abstract
The utility model relates to a dredging pipe flanging device used in the dredging pipe flanging field. The technology project is that the circumference of a platen 1 is radially distributed with above two round holes corresponding to bolt holes of a flange plate on a pipe joint 5 end; the round holes are penetrated by a lead screw drive 9 whose one end matches with a handle 2 through screws and whose other end is inserted into the bolt holes of the flange plate on the pipe joint 5 and fixedly connected with the flange plate. The matching surface of the platen 1 and the pipe joint 5 is provided with a flange 10 in splicing fit with the internal wall of the pipe joint; the outer end face of the flange 10 is in cone shape; the outer joint of the flange 10 and the platen 1 is in arc shape. The utility model has the advantages of simple structure, easy use, security and uniform flanging, and solves the defect existing in current dredging pipe flanging method.
Description
One, technical field: the utility model relates to a kind of special equipment of pipeline construction, especially for the dredging pipe hemmer in dredging pipe flange field.
Two, background technology: two dredging pipes are in carrying out docking operation, apposition position need use encapsulant that it is sealed, the method of using is that liner PE pipe is inserted in the pipe fitting at present, it is softening that the mode of heating makes the PE pipe in utilizing then, will be reserved in the outer part of pipe fitting with artificial mode and outwards turn down.This mode is unusual inconvenience in use, and efficiency of construction is low, labour intensity is big, and it is inhomogeneous to rout up the limit of coming, and is difficult for typing, produces bounce-back.
Three, summary of the invention: the purpose of this utility model is exactly the above-mentioned defective that exists at prior art, and a kind of convenient dredging pipe hemmer that uses is provided.
Its technical scheme is: at the peripheral radial of pressing plate 1 two the above circular holes that distributing, circular hole is corresponding with the bolt hole of the ring flange of pipe fitting 5 ends, be penetrated with screw mandrel 9 in the circular hole, one end of screw mandrel 9 and rocking handle 2 threaded engagement, the other end inserts the flange plate bolt hole of pipe fitting 5 and fixedlys connected with ring flange, be provided with the chimb 10 of pegging graft and cooperating with pipe fitting inner wall on the involutory surface of pressing plate 1 and pipe fitting 5, the outer face of chimb 10 is tapered, and the outer joint portion of chimb 10 and pressing plate 1 is curved.Screw mandrel 9 is connected with the ring flange of pipe fitting 5 by the trapezoidal bolt 3 of band self-locking.Such scheme also comprises the internal expension ring 4 of device in pipe fitting 5, internal expension ring 4 comprises arc briquetting 12 compositions that pipe nipple 11 and two ends are threaded and cooperate support bar 13 and be fixed on two support bar 13 outer ends, middle part at pipe nipple 11 radially offers the circular hole that cooperates with inserted link, and the external screw thread of the internal thread of pipe nipple 11 and two end supports bar 13 forms synchronous opposite direction threaded engagement.Also have with pipe fitting 5 and support the bracing frame 7 that cooperates.
Effect of the present utility model is: simple in structure, easy to use, safe, flange is even, and easily typing does not produce bounce-back, has solved the defective that present dredging pipe flange mode exists.
Four, description of drawings:
Accompanying drawing 1 is the utility model structural representation;
Accompanying drawing 2 is that the A of Fig. 1 is to part sectioned view;
Accompanying drawing 3 is structural representations of pressing plate;
Accompanying drawing 4 is structural representations of internal expension ring.
Five, the specific embodiment:
As shown in the figure, peripheral radial at pressing plate 1 is uniform-distribution with two above circular holes, circular hole is corresponding with the bolt hole of the ring flange of pipe fitting 5 ends, be penetrated with screw mandrel 9 in the circular hole, one end of screw mandrel 9 and rocking handle 2 threaded engagement, the other end are inserted the flange plate bolt hole of pipe fitting 5 and are fixedlyed connected with ring flange, are provided with the chimb 10 that cooperates with the pipe fitting inner wall grafting on the involutory surface of pressing plate 1 and pipe fitting 5, the outer face of chimb 10 is tapered, and chimb 10 is curved with the outer joint portion of pressing plate 1.Screw mandrel 9 is connected with the ring flange of pipe fitting 5 by the trapezoidal bolt 3 of band self-locking.Internal expension ring 4 is housed in pipe fitting 5, internal expension ring 4 comprises arc briquetting 12 compositions that pipe nipple 11 and two ends are threaded and cooperate support bar 13 and be fixed on two support bar 13 outer ends, middle part at pipe nipple 11 radially offers the circular hole that cooperates with inserted link, and the external screw thread of the internal thread of pipe nipple 11 and two end supports bar 13 forms synchronous opposite direction threaded engagement.Be provided with the bracing frame 7 that cooperates with pipe fitting 5 supports in the bottom of pipe fitting 5.
During use, be placed in the dredging pipe that needs on the support to process putting on the PE pipe, with internal expension ring 4 PE pipe and steel pipe (pipe fitting) axial location are fixed, trapezoidal bolt 3 with the band self-locking, screw mandrel 9, pressing plate 1, advance rocking handle 2 to be connected on the flange 8 that welds on the steel pipe fast, with heater the PE pipe 6 that needs flange is carried out outer heating then, when temperature reaches requirement, with quick propelling rocking handle 2 pressing plate 1 is advanced fast, make the even flange of the outer end generation circumferencial direction of PE pipe, device with being useful on flange after supercooling takes off, and then finishes the making of this dredging PE pipe flange.Squeeze the PE tubing of hindering liner when pressing plate is pushed ahead, form weak spot, the joint portion design has the arc structure that caves in outside pressing plate 5 and its chimb 10.
