Abstract

Boiler header and water-cooling wall welding auxiliary device. The adjacent water wall tubes are pressed downwards to cause dislocation to be more serious in the tilting process because the adjacent water wall tubes are used as fulcrums, and whether the adjacent water wall tubes are aligned after tilting can not be known in the tilting process, and the situation that the displacement is excessive and reverse pressing is needed to adjust after tilting is found, so that the progress and the efficiency of construction are seriously influenced. The utility model discloses the constitution includes: punch holder (2), lower plate (4) and roof (7), the punch holder with the lower plate make-up arrange, the top of punch holder be fixed with hydraulic push rod (1), hydraulic push rod's extension bar with the roof fixed, four bights of roof articulated respectively have pull rod (3), the lower extreme of pull rod pass the punch holder with the lower plate correspond the bar groove (5) of position. The utility model is used for boiler header and water-cooling wall welding are supplementary.

Description

Auxiliary device for welding boiler header and water-cooled wall

Technical Field

The utility model relates to a boiler header and water-cooling wall welding auxiliary device.

Background

All be when boiler water wall welds with the header and adjust the tube head of header well with the water wall pipe then weld, because the condition of misplacing about can appearing in the tube head of water wall pipe and header, consequently need constructor to adopt the crowbar with the end perk of water wall pipe in order to reach the purpose of adjusting well with the tube head of header, but owing to be with adjacent water wall pipe as the fulcrum at the in-process of perk, consequently can make its dislocation more serious with adjacent water wall pipe pushing down, whether can't learn behind the perk simultaneously in-process and adjust well, discover to shift after the perk excessively to need reverse pushing down to adjust, seriously influence the progress and the efficiency of construction.

Disclosure of Invention

The utility model aims at the not enough of prior art, the utility model provides a boiler header and water-cooling wall welding auxiliary device to solve the problem that proposes in the above-mentioned background art.

The above purpose is realized by the following technical scheme:

the utility model provides a boiler header and water-cooling wall welding auxiliary device, its constitution includes punch holder, lower plate and roof, the punch holder with the lower plate buckle and arrange, the top of punch holder be fixed with hydraulic push rod, hydraulic push rod's extension bar with the roof fixed, four bights of roof articulated respectively have a pull rod, the lower extreme of pull rod pass the punch holder with the lower plate correspond the bar groove of position.

The boiler header and the water wall welding auxiliary device, the bottom of the pull rod is provided with a stop block.

Has the advantages that:

1. the utility model discloses a with the device centre gripping in the welding department of header tube head and water-cooled wall pipe end, through hydraulic push rod's release for punch holder and lower plate realize the cross-under gradually, accomplish about header tube head and water-cooled wall pipe end dislocation adjust well.

2. The utility model discloses simple structure, when carrying out header tube head and water wall tube end alignment, can not exert an influence to other water wall tubes, the two real adjusting well behind the adjustment position can be realized through the make-up of punch holder and lower plate to the back simultaneously.

Description of the drawings:

FIG. 1 is a front view of the present invention;

fig. 2 is a side view of the present invention;

fig. 3 is a bottom view of the present invention;

FIG. 4 is a schematic structural view of the present invention in use;

in the figure: 1. a hydraulic push rod; 2. an upper splint; 3. a pull rod; 4. a lower splint; 5. a strip-shaped groove; 6. a stopper; 7. a top plate; 8. collecting a box; 9. a water cooled wall; 10. a slot plate.

The specific implementation mode is as follows:

example 1:

the utility model provides a boiler header and water-cooling wall welding auxiliary device, its constitution includes punch holder 2, lower plate 4 and roof 7, the punch holder with the lower plate make-up arrange, the top of punch holder be fixed with hydraulic push rod 1, hydraulic push rod's extension bar with the roof fixed, four bights of roof articulated respectively have pull rod 3, four bights at top have welded frid 10 respectively, the frid is connected through the pivot with the pull rod, the lower extreme of pull rod pass the punch holder with the lower plate correspond the bar groove 5 of position.

Example 2:

according to the auxiliary device for welding the boiler header and the water wall in the embodiment 1, the bottom of the pull rod is provided with a stop block 6.

The working principle is as follows: hydraulic jack is chooseed for use to hydraulic push rod, when using, as shown in fig. 4, stretch into the lower extreme between 8 tube heads of collection box and the 9 tube ends of water-cooling wall with the lower plate earlier, then detain on the water-cooling wall tube end, detain the upper end between collection box tube head and water-cooling wall tube end with the punch holder, then rotate every pull rod, make every pull rod rotate supreme, in the bar inslot of lower plate, the jack is pressed to this moment with the hand reciprocal, make the extension bar of jack drive roof up-going, make the pull rod hang the lower plate behind the roof motion, because the bottom of pull rod has the dog, make pull rod pulling lower plate up-going, make the tube end of water-cooling wall lifted until being adjusted well with the collection box tube head in the in-process of up-going.

Claims

1. The utility model provides a boiler header and water-cooling wall welding auxiliary device which characterized by: the upper clamping plate and the lower clamping plate are arranged in a buckled mode, a hydraulic push rod is fixed to the top of the upper clamping plate, an extension rod of the hydraulic push rod is fixed to the top plate, four corners of the top plate are respectively hinged to a pull rod, and the lower end of the pull rod penetrates through the strip-shaped grooves in the corresponding positions of the upper clamping plate and the lower clamping plate.

2. The boiler header and waterwall welding assist device of claim 1, wherein: the bottom of the pull rod is provided with a stop block.
