Description

The welder in narrow space in the air preheater module
Technical field
The utility model relates to the welder in narrow space in a kind of air preheater module, relates in particular to a kind of welder that is suitable for the interior narrow space of air preheater module of narrow space welding operation, belongs to the welder technical field.
Background technology
To the large welded structures spare of forming by part of the steel plate, as structures such as huge revolving regenerative air heater rotor, box or shallow/deep groove type steel structure columns, when the assembly unit of erecting bed, a lot of occasions adopt the fillet welding welding manner, some occasion is because spacing is too small between the part, device height is excessive, the weld seam present position degree of depth exceeds people's arm length, cause welding personnel can't enter interior construction, or construct by the mode of lengthening welding gun operation brachium, the welding quality in weld seam centre position is difficult to guarantee.
For addressing this problem, traditional design adopts amplifies on-the-spot welding operation space, guarantee that welding personnel can enter welding operation in the member, often make scantling huge, to air preheater rotor, after structure large-scaleization, can't adopt small size storehouse lattice, cause near the constructional difficulties of central tube, also influenced the reasonability of overall construction design.
Summary of the invention
The purpose of this utility model provides a kind of welder that is suitable for the interior narrow space of air preheater module of narrow space vertical position welding.
For realizing above purpose, the technical solution of the utility model provides the welder in narrow space in a kind of air preheater module, it is characterized in that, by welding gun, the welding gun folder, walking dolly, wig-wag, two tracks, suspension hook, control box, suspension ring, wire clamp, control line, the guiding runner, set bolt, fixed mount, magnet-wheel, base and set bolt are formed, walking dolly moving up and down is located on dismountable two tracks, the walking dolly bottom is connected with welding gun by wig-wag, top is connected with control box by control line, welding gun is connected with wire-feed motor with wire clamp by the welding gun folder, the bottom of two tracks is provided with base, base is provided with at least three magnet-wheels by set bolt, upper end at two tracks is provided with fixed mount, the top is provided with suspension ring, and the lower end of fixed mount is provided with the guiding runner, and two ends are provided with set bolt.
The utility model adopts the guider of guide rail as welding tractor, welding tractor is guided into the welding position, use electromagnet, locator card, movable pulley is auxiliary, assurance equipment moves and the location in job area flexibly, adopt the automatic feeding mode to carry welding wire, control weld width with wig-wag, the assurance moulding is attractive in appearance, control the welded seam height with regulating wire feed rate and carriage walking speed, because the weld seam two ends are influenced by the guide rail fixed component, can not weld automatically, on the guide rail fixed base plate, add the fixing interim member that extends, with extensible track length, then weld seam adopts weldering automatically entirely.
The utility model has the advantages that:
1. efficiently solve the weld seam operation problem of the crawl space of rotary preheater rotor component inside, the minimum space width can be little of 200mm;
2. not needing to do special processing, also can be level or smaller or equal to the narrow space weld construction at 90 ° of inclinations angle in the welding position;
3. reduce welder's manipulation strength;
4. improve welding quality and speed of welding, welding efficiency is 3~4 times of manual welding;
5. can guarantee welding quality.
Description of drawings
Fig. 1 is the welder structural representation in narrow space in the air preheater module;
Fig. 2 is the understructure schematic diagram.
The specific embodiment
The utility model is described in further detail below in conjunction with drawings and Examples.
Embodiment
As shown in Figure 1, be the welder structural representation in narrow space in the air preheater module, the welder in narrow space is made up of welding gun 1, welding gun folder 2, walking dolly 3, wig-wag 4, two tracks 5, suspension hook 6, control box 7, suspension ring 8, wire clamp 9, control line 10, guiding runner 11, set bolt 12, fixed mount 13, magnet-wheel 14, base 15 and set bolts 16 in the described air preheater module.
Track 5 uses the mode of 1.5m * 2 piece to realize the length that requires of 3m, site requirements when reducing lifting, boss is used in the junction, stiffener, realize the stability of track 5, increase anti-dismounting degree, boss installs suspension ring in addition additional, makes lifting more convenient, according to the use occasion difference, rotary preheater rotor design height requires different, open fixing hole on the guide rail at a certain distance, regulate highly needs, can move up and down walking dolly 3 and be installed on two tracks 5 by clutch to adapt to, walking dolly 3 adopts heavy-duty motor, the height ratio decelerator makes walking dolly 3 more stable when low speed is walked, at the uniform velocity, allow the weld seam equilibrium, walking dolly 3 volumes are little, and are in light weight, are convenient to welding, walking dolly 3 bottoms are connected with welding gun 1 by wig-wag 4, top is connected with control box 7 by control line 10, and walking dolly 3 adopts the walking of the rack-and-pinion kind of drive, operates steadily; Be furnished with oscillator of welding gun 4 on the walking dolly, guarantee that welding quality and moulding are attractive in appearance, minimizing is splashed, and three meters long track adopts the removably design, conveniently uses at the different work environment; The complete equipment light and flexible, easy to carry, not fragile, be fit to different operation occasions, control box 7 is avoided the drawback that can't operate under small space or the adverse circumstances. and can carry out single many operations, reduce workman's fatigue strength, save human input, realize Automation of Welding.The silk that welding gun 1 is sent by welding gun folder 2 and wire clamp 9 and wire-feed motor is connected, the bottom mounting seat 15 of two tracks 5, as shown in Figure 2, base 15 is installed three magnet-wheels 14 by set bolt 16, at the upper end of two tracks 5 mounting and fixing support 13, this device adopts two point location modes, assurance equipment moves and the location in job area flexibly, increase track stability welding gun is moved along weld seam, guarantee welding quality, the top is provided with suspension ring 8, guiding runner 11 is installed in the lower end of fixed mount 13, two ends install and fix bolt 12, can alleviate the circuit complications of each circuit because of rising and being produced. and make welding process more level and smooth, smooth and easy.
