A branch pipe welding protective device is characterized by mainly comprising a fixing plate (1) and two movable plates (2), wherein the two movable plates (2) are connected with the straight edges of the fixing plate (1) through hinges (3), a pull bar (4) is arranged on the fixing plate (1), the fixing plate (1) and the movable plates (2) form a circular plate structure, and a matching arc sealing layer (5) is arranged on arc edges of the fixing plate (1) and the movable plates (2). The protective device substantially improves the quality of a welding area, and prolongs the integral service lifetime of a branch pipe and a main pipe. The protective device saves great quantity of argon, improves work efficiency and saves cost.
Description
Technical field
The utility model relates to a kind of welding tooling, the welding protection device for minimizing protection gas consumption that especially a kind of needs use when carrying out gas shielded welding, specifically a kind of branch pipe welding protective device.
Background technology
The supervisor that can't pierce for the people; when needing branch pipe welded directly to the run pipe, because on-the-spot problems such as pipeline is long, pipeline and equipment connections, welding can't be carried out gas shield; therefore welding region has serious oxidation situation and occurs; the corrosion resistance of material and intensity can reduce greatly like this, if pipe ends is sealed when protecting, need be filled with continuously argon gas in pipeline; like this; very large of the use amount of argon gas, and wait for that argon gas is full of pipeline and also needs the long period, cause efficient lower.To this, the solution that there is no at present.
Summary of the invention
If the purpose of this utility model is to adopt gas shielded arc welding during for existing slender pipeline branch pipe welding then exist gas consumption large; cycle is long; efficient is low; if do not adopt gas shielded arc welding; then can affect the problem of welding position corrosion resistance; design a kind of simple in structure, easy for operation and can greatly reduce the branch pipe welding protective device of gas consumption.
The technical solution of the utility model is:
The utility model is by increasing an adjustable baffle at supervisor and arm relative position place; welding region is sealed relatively; only need to pass into a small amount of protective gas to baffle and branch pipe welding position and can realize gas shielded arc welding, concrete protection structure is as follows:
A kind of branch pipe welding protective device is characterized in that it mainly is comprised of a fixed head 1 and two portable plates 2, and described two portable plates 2 link to each other with two straight flanges of fixed head 1 by hinge 3, at fixed head 1 pull bar 4 are installed; Described fixed head 1 and portable plate 2 forms a Circular plate structure, at the arc-shaped side of described fixed head 1 and portable plate 2 the arc sealant 5 that matches is installed.
Described hinge 3 is Ω shape structure, and its end is fixedly linked with portable plate after passing installing hole on the portable plate 2, and the other end is actively plugged in the installing hole on the fixed head 1.
The connecting rod 402 that described pull bar 4 is fixedly linked by bulb 401, with bulb 401 and form with lifting rod 403 that connecting rod 402 is flexibly connected, described bulb 401 and lifting rod 403 lay respectively at the up and down two sides of fixed head 1, and lifting rod 403 is flexibly connected by bearing pin 404 and connecting rod 402.
Described arc sealant 5 is the refractory wool sealant.
The beneficial effects of the utility model:
The utility model can obviously improve the quality of welding region, prolongs arm and supervisor's whole service life.
The utility model can be saved a large amount of argon gas, increases work efficiency, and saves cost.

The specific embodiment
Below in conjunction with drawings and Examples the utility model is further described.
Shown in Fig. 1-5.
A kind of branch pipe welding protective device, it mainly is comprised of a fixed head 1 and two portable plates 2, and shown in Fig. 1-2, described two portable plates 2 link to each other with two straight flanges of fixed head 1 by hinge 3, at fixed head 1 pull bar 4 are installed; Described fixed head 1 and portable plate 2 forms a Circular plate structure, at the arc-shaped side of described fixed head 1 and portable plate 2 the arc sealant 5 that matches is installed.Hinge 3 can adopt pipe to be bent into the Ω shape structure shown in Fig. 3,4 during implementation, and its end is fixedly linked with portable plate after passing installing hole on the portable plate 2, and the other end is actively plugged in the installing hole on the fixed head 1.The structure of pull bar 4 can adopt structure shown in Figure 5, the connecting rod 402 that it is fixedly linked by bulb 401, with bulb 401 and form with lifting rod 403 that connecting rod 402 is flexibly connected, described bulb 401 and lifting rod 403 lay respectively at the up and down two sides of fixed head 1, and lifting rod 403 is flexibly connected by bearing pin 404 and connecting rod 402.Arc sealant 5 is take the refractory wool sealant as best.
During concrete the manufacturing, it is the BFe30-1-1 copper coin of 1～2mm that the fixed head of composition Circular plate structure and movable material can adopt thickness, the portable plate of both sides passes through gemel connection, hinge one end points is welded on the fixed head of plectane, the other end and portable plate are at an angle, as shown in Figure 3, make the portable plate 2 can be freely sagging.During protection, the arcuate directions of portable plate 2 align with tube is fitted plectane and inner-walls of duct.
The effect of refractory wool is to reach good sealing effectiveness after copper coin and inner-walls of duct are fitted.
Pull bar 4 ends are designed to chondritic and look into pull bar can be rotated freely in the plane, and design connects bearing pin can make copper coin rotate freely in the locus, shown in 5 figure.When the utility model need to be put into more small-bore adapter like this, can change the orientation by rotating tension bar and realize.When putting into downwards, loose-leaf rotates freely, and conveniently puts into the less arm in aperture. and bearing pin is set on the pull bar pull bar is rotated freely, put into after can tilting, as shown in Figure 6.After putting into, to by pull bar 4 fixed head upwards being carried, loose-leaf is rotated down, and is similar radian to the cylinder inwall, makes copper coin and cylinder inner wall gluing, sealing by refractory wool.A small amount of undesirable cotton of fitting can be by cotton improvement of local increase high temperature, as shown in Figure 7.
The utility model does not relate to partly all, and the prior art that maybe can adopt same as the prior art is realized.
