Abstract

A gas protector of a welded back surface inside a circular seam of a cylindrical container consists of a perforated tube with an air inlet, an arc-shaped square groove, a supporting guide tube with a plurality of adjusting holes, locking bolts, a sleeve with orifices and a bottom plate. The lower end of the sleeve is fixedly connected with the bottom plate, the lower end of the supporting guide tube is inserted in the sleeve, the supporting guide tube is fixedly connected with the sleeve via the locking bolts, the front ends of the locking bolts are inserted in the holes of the supporting guide tube after penetrating through the orifices of the sleeve, the perforated tube is connected with the arc-shaped square groove together, the air inlet of the perforated tube is located outside the arc-shaped square groove, and the arc-shaped square groove is supported at the top of the supporting guide tube. The gas protector can effectively protect the welded annular seam on the back surface of the annular seam during welding of the inner surface of the annular seam, and increases welding quality of the welded seam.

Description

Hydrostatic column circumferential weld interior welds backside gas protective device
Technical field
The utility model relates to a kind of hydrostatic column circumferential weld interior welds backside gas protective device, extraneous gas protection when being used for hydrostatic column cylindrical shell circumferential weld interior welds.
Background technology
At present, when the argon arc welding of cylindrical tube body circular seam connect, the welding back side can't form evenly lasting gas shield; cause the oxidation of the circumferential weld back side; influence the product welding quality, former protective device can't form effective protection for protective gas is directly rushed at fixedly pad.
Summary of the invention
The purpose of this utility model provides a kind of hydrostatic column circumferential weld interior welds backside gas protective device, and it can effectively be protected the circumferential weld of welding at the circumferential weld back side when the circumferential weld inner surface welds, and improves the welding quality of weld seam.
The technical scheme that realizes above-mentioned purpose is: a kind of hydrostatic column circumferential weld interior welds backside gas protective device; by the antipriming pipe of bringing gas port into; the arc square groove; supporting tube with a plurality of adjustment holes; clamping screw; narrow meshed sleeve pipe and base plate are formed; fixedly connected with base plate in the lower end of sleeve pipe; the lower end of supporting tube is inserted in the sleeve pipe; and supporting tube is fixedlyed connected with sleeve pipe by clamping screw; the front end of clamping screw inserts in the hole of supporting tube after passing the aperture of sleeve pipe; antipriming pipe and arc square groove link together; and the air inlet of antipriming pipe is positioned at outside the arc square groove, and the arc square groove is supported on the supporting tube top.
After adopting technique scheme; use the arc square groove to press close to the required girth weld back side; by to the arc square groove towards protective gas; the flow that keeps protective gas in the arc square groove; guarantee to form evenly lasting protective gas; thereby when the circumferential weld inner surface welds, the circumferential weld of welding is effectively protected, improved the welding quality of weld seam at the circumferential weld back side.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
The specific embodiment
Below in conjunction with drawings and Examples the utility model is described in further detail.
As shown in Figure 1; a kind of hydrostatic column circumferential weld interior welds backside gas protective device; by the antipriming pipe 1 of bringing gas port into; arc square groove 2; two supporting tubes 3 with a plurality of adjustment holes; two clamping screws 4; narrow meshed two sleeve pipes 5 and base plate 6 are formed; fixedly connected with base plate 6 in the lower end of two sleeve pipes 5; the lower end of two supporting tubes 3 is inserted in respectively in the corresponding sleeve pipe 5; and supporting tube 3 is fixedlyed connected with sleeve pipe 5 by clamping screw 4; the front end of clamping screw 4 inserts in the hole of supporting tube 3 after passing the aperture of sleeve pipe 5; antipriming pipe 1 links together with arc square groove 2; and the air inlet of antipriming pipe 1 is positioned at outside the arc square groove 2, and arc square groove 2 is supported on supporting tube 3 tops.Base plate 6 can be done ovalisation or other shape.
A plurality of adjustment holes on the supporting tube 3 are evenly distributed.
Use of the present utility model is as follows:
Before carrying out gas shield with this device, sleeve pipe 5 and base plate 6 welded mutually form one and stablize bearing; 1 antipriming pipe 1 and the arc square groove 2 of bringing gas port into linked together, and the air inlet of antipriming pipe 1 is placed on arc square groove 2 is outer is convenient to air inlet, prop up the arc square groove, insert in the sleeve pipes 5 supporting tube 3 fixing again with clamping screw 4 with supporting tube 3.Before using bulge is placed on the adjustable turning rolls, and device is placed on the cylindrical tube below, regulate the height of arc square groove 2 by regulating bolt 4, make it press close to the cylindrical shell girth joint, source of the gas is connected with air inlet, evenly air inlet, turning rolls is adjusted to the welding revolution, weld.
