Description
Technical field
The utility model relates to the sacrificial anode soldering appliance, and especially a kind of long-rod type sacrificial anode soldering appliance, be mainly used in the occasion that the industries such as combustion gas, running water are carried out the installation of steel pipe sacrificial anode.
Background technology
According to regulations such as anticorrosion standard GB/T 21448-2008 " buried steel pipeline cathode protection technology standard " and CJJ95-2003 " Buried City Gas Steel Pipeline corrosion control technology rules "; in-service buried steel pipeline need progressively append cathodic protection, and pipeline suitable employing in cities and towns is installed the method for sacrificial anode additional and carried out the cathodic protection of pipeline.At present, on burning line, the welding of sacrificial anode generally adopts the exothermic welding connection technology, and used tool mainly contains igniter and exothermic welding box.
During concrete operations, mould is placed on to rust cleaning zone central authorities, cable copper core is inserted to the mold bottom hole slot and is close on tube wall, solder flux and igniting powder are sprinkling upon to solder flux surface and die edge, build mould, the igniting powder of lighting die edge with igniter makes it the vigorous reaction burning, withdraws after cooling mould and gets final product.This welding method is simple, easy left-hand seat, and soldering appliance is light, during welding, does not also need with external power supply or thermal source.During due to this instrument of employing, the operator needs near pipe operations, therefore not to be suitable for the welding operation in the narrow space zone, the potential safety hazards such as the slight blast produced in the time of also can't avoiding lighting a fire, smog.
The utility model content
The purpose of this utility model is to provide a kind of long-rod type sacrificial anode soldering appliance, to solve the long Welding Problems apart from narrow space.
For achieving the above object, the utility model adopts following technical scheme:
A kind of long-rod type sacrificial anode soldering appliance, comprise exothermic welding box, fixed frame, electronic lighter, long handle action bars, pull-switch, the long handle action bars is connected and fixed frame, the exothermic welding box is arranged in fixed frame, electronic lighter is comprised of pulse igniter and ignition electrode, and electronic lighter is fixed near the exothermic welding box, and the electric wire of pulse igniter extends along the long handle action bars, be connected with pull-switch from handheld terminal is drawn, by pull-switch, control sparking.
Also be provided with cord grip in the fixed frame periphery, for making anode cable, be close to pipeline, guarantee welding quality.Cord grip can make anode cable vertically be close to weldering box sidepiece by fixture, prevents rocking of electric wire in welding process, and fixture can adopt metal fixture.
Pulse igniter is arranged on fixed frame, extends to from igniter from the ignition electrode of drawing near the medicine containing opening of weldering box top, and is controlled in safe sparking scope with the distance of welding agent.
The long handle action bars is hollow structure, and an end and fixed frame are threaded connection, and aperture is opened on other end top, and the electric wire of pulse igniter, through long handle action bars inside, is drawn with pull-switch and is connected from aperture.
The bar head of long handle action bars is equipped with the rubber antiskid taper knob, facilitates the integrated moving of instrument and lifts.
Wherein, described exothermic welding box is market exothermic welding box commonly used, and bottom is with the anode cable groove.
The utility model is to convert on existing exothermic welding instrument basis, therefore possesses the advantage of existing instrument, simultaneously, because the staff is operated away from pipeline, the potential safety hazard of bringing because producing slight blast, smog etc. in the time of can effectively avoiding lighting a fire, there is good operability and reliability, practical value is widely arranged.
The accompanying drawing explanation
The structure chart that Fig. 1 is long-rod type sacrificial anode soldering appliance of the present utility model.
1-Anti-slip handle cover, 2-long handle action bars, 3-electric wire, 4-pull-switch, 5-pulse igniter, 6-ignition electrode, 7-fixed frame, 8-exothermic welding box.
The specific embodiment
Below in conjunction with accompanying drawing, the technical solution of the utility model is carried out to clear, complete description.
As shown in Figure 1, exothermic welding box 8 is arranged in fixed frame 7, pulse igniter 5 is arranged on fixed frame 7, the ignition electrode 6 of drawing from pulse igniter 5 extends near the medicine containing opening of weldering box 8 tops, and keep certain sparking distance with welding agent, long handle action bars 2 is hollow structure, one end and fixed frame 7 are threaded connection, aperture is opened on other end top, the electric wire 3 of pulse igniter 5 is through the inside of long handle action bars 2, extend along long handle action bars 2, be connected with pull-switch 4 from handheld terminal is drawn, by pull-switch 4, control sparking.The bar head of long handle action bars 2 is equipped with rubber antiskid taper knob 1, facilitates moving and lifting of instrument integral body.Also be provided with cord grip in fixed frame 7 peripheries, cord grip makes anode cable be close to the outer wall of exothermic welding box 8 by fixture, prevents rocking of welding process Anodic cable, guarantees welding quality, and wherein fixture can adopt metal fixture.
Wherein, described exothermic welding box 8 is market exothermic welding box commonly used, and bottom is with the anode cable groove.
Before welding, first peel the insulating corrosion layer of anode cable off, expose one section copper core, anode cable is welded to box 8 sidepieces perpendicular to weldering box 8 by being placed under upper, termination exceeds the weldering box 8 about 50mm in bottom, the anode cable line is exceeded to part along 90 ° of bendings of weldering box 8 horizontal direction, make anode cable copper core insert weldering box 8 bottom hole slots.After pouring solder flux and igniting powder into, instrument integral body is placed on to rust cleaning zone top, presses downwards, make to weld box 8 and combine closely in soldered steel-tube construction surface.Connect with the mains, utilize the pull-switch sparking, light solder flux, carry out combustion reaction.After cooling, unclamp cord grip and complete welding.
