Abstract
The utility model discloses a welding auxiliary device of a membrane type water wall. The welding auxiliary device of the membrane type water wall comprises a pull rod, a baffle is arranged at one end of the pull rod, and the position, close to the baffle, of the pull rod is sequentially sleeved with an expansion sleeve and a supporting device. Due to the arrangement of the expansion core, when the device is pressed, the inner wall of a pipeline can be adequately tensioned, a good role in controlling the error of a membrane type wall pipe row pitch and reducing welding deformation is played, and meanwhile the welding auxiliary device is simple in structure, and convenient to dismount, and solves the problems that in the existing membrane type water wall welding process, size deviation easily happens, and product quality is reduced.
Description
Technical field
The utility model belongs to boiler manufacturing technology field, is specifically related to a kind of auxiliary welding equipment of fin panel casing.
Background technology
In boiler structure design, fin panel casing because its air-tightness is good, be convenient to install, can simplify furnace wall structure simultaneously, alleviate the many merits such as furnace wall weight and be used widely.The height of membrane wall pipe row manufacture level is the important scale of weighing a Boiler Manufacturing Enterprise technical merit.In membrane wall pipe row's welding process, be subject to the impact of membrane wall welding equipment structure, thereby need to install auxiliary welding equipment additional at tube end, play control valve row pitch error, reduce welding deformation, guarantee the effect of fin panel casing quality.
Utility model content
The purpose of this utility model is to provide a kind of auxiliary welding equipment of fin panel casing, to solve in existing fin panel casing welding process, easily produces dimensional discrepancy, reduces the problem of product quality.
The technical scheme that the utility model adopts is, a kind of auxiliary welding equipment of fin panel casing, comprises pull bar, and one end of pull bar is provided with baffle plate, on pull bar near the position of baffle plate successively cover have expansion gear and bracing or strutting arrangement.
Feature of the present utility model is also,
Expansion gear wherein comprises that two are enclosed within on pull bar and the hollow cone coaxial with pull bar, the adjacent setting in top of two cones, and the outside cover of two cones has expansion core, and expansion core is clamped in cone with jump ring.
Expansion core wherein comprises three fan-shaped bodies, and the lateral surface of each fan-shaped body is equipped with zigzag slot.
Bracing or strutting arrangement wherein comprises nut, hollow support plate, hollow steel pipe and cutting ferrule, pull bar is successively from cutting ferrule, steel pipe, support plate and nut shaft to passing, cutting ferrule is hollow boss structure, and the side that cutting ferrule diameter is larger is fixedly connected with steel pipe, and cutting ferrule is positioned at the side near cone.
The beneficial effects of the utility model are, by the setting of expansion core of the present utility model, make its swelling inner-walls of duct fully when pressurized, control membrane wall pipe row pitch error, minimizing welding deformation are played a good role, meanwhile, apparatus structure of the present utility model is simple, convenient disassembly, solved in existing fin panel casing welding process and easily produced dimensional discrepancy, reduced the problem of product quality.
Accompanying drawing explanation

Fig. 2 is the structural representation of expansion core in the auxiliary welding equipment of the utility model fin panel casing;
Fig. 3 is expansion core three lobe hoop layout drawings in the auxiliary welding equipment of the utility model fin panel casing.
In figure, 1. pull bar, 2. nut, 3. support plate, 4. steel pipe, 5. cutting ferrule, 6. cone, 7. expansion core, 8. jump ring, 9. baffle plate.
The specific embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is elaborated.
The structure of the auxiliary welding equipment of the utility model fin panel casing as shown in Figure 1, comprise pull bar 1, one end of pull bar 1 is provided with baffle plate 9, on pull bar 1, from overlapping and have expansion gear and bracing or strutting arrangement successively near the position of baffle plate 9, wherein, expansion gear comprises two cones 6, each cone 6 is and is enclosed within on pull bar 1 and the hollow cone coaxial with pull bar 1, the adjacent setting in top of two cones 6, the outside cover of two cones 6 has expansion core 7, and expansion core 7 use jump rings 8 are clamped in cone 6; As shown in Figure 2, expansion core 7 comprises three fan-shaped bodies, and the lateral surface of each body is equipped with zigzag slot; Bracing or strutting arrangement comprises nut 2, hollow support plate 3, hollow steel pipe 4 and cutting ferrule 5, pull bar 1 axially passes from cutting ferrule 5, steel pipe 4, support plate 3 and nut 2 successively, cutting ferrule 5 is hollow boss, and the side that cutting ferrule 5 diameters are larger is fixedly connected with steel pipe 4, and cutting ferrule 5 is positioned at the side near cone 6.
Under the loose unloading state of this device expansion core 7, insert in the pipeline of fin panel casing the one end of pull bar 1 being equipped with to expansion core 7, and the shoulder of cutting ferrule 5 and pipeline end face are adjacent to; With spanner rotating tension bar 1, the spacing between baffle plate 9 and cutting ferrule 5 is dwindled gradually, promote two cone 6 relative motions, apply pressure in expansion core 7, expansion core 7 is along the cone face diameter of cone 6 to strutting, thereby is full of and stretching inner-walls of duct.
After welding, rotate backward pull bar 1, baffle plate 9 becomes greatly gradually with the spacing of cutting ferrule 5, and jump ring 8 is out of shape gradually replys, thereby after straining expansion core 7 and radially dwindling, can from pipeline, take out.As shown in Figure 3, the material of expansion core 7 is senior carbon tool steel T10A, and point three lobe hoops are arranged.Hoop sawtooth pattern groove is carved with on expansion core 7 surfaces, thereby makes it when with pipe swelling, have larger contact area and frictional force, increases pulling-out force.
There is following shortcoming in existing fixed core hair style skirt: core print is slightly greatly affected by thermal expansion and contraction after membrane wall pipe row welding, and core print cannot be dismantled; Core print is slightly little can not be played control valve row's pitch error and reduce welding deformation.Adopt this device can avoid the appearance of the problems referred to above, make membrane wall pipe row workmanship higher.
