Description
Technical field
The utility model belongs to the blast furnace installation auxiliary device, especially relates to a kind of last furnace shell electro-gas (enclosed) welding welding with organizing carriage.
Background technology
In the blast furnace systems installation engineering, last furnace shell, hot-air stove shell and gravitational precipitator housing all owing to its housing volume is big, Heavy Weight, normally are prefabricated in the factory into earlier the 3-4 sheet; Organize at the construction field (site) then after becoming band and install, the furnace shell of blast furnace system is installed and is all adopted welding automatically mostly at present, and the right upright seam of furnace shell group adopts the electrogas welding machine welding; For the ease of the furnace shell welding, use No. 40 I-steel soldering group to carriage usually at the construction field (site), because the carriage volume is big; The inconvenience transportation, in case engineering finishes, this carriage often disintegrates and handles as waste wood; No longer reuse, both waste material had increased construction cost again.
Summary of the invention
The purpose of the utility model is to propose a kind of electro-gas (enclosed) welding welding of detachable last furnace shell with organizing carriage, and reusable, labor and material saving reduces construction cost.
The electro-gas (enclosed) welding welding that the purpose of the utility model is achieved in that a kind of detachable last furnace shell, is characterized in that carriage with group: the electro-gas (enclosed) welding welding of this detachable last furnace shell with group to carriage mainly by central frame, short beam I, long girder, short beam II and auxiliary girder composition; This central frame is regular polygon; And this central frame can be the octagon framework, and this central frame can form the short beam I of the flanged dish in outer end that is welded respectively in the middle part of the lateral surface on each limit of heart framework hereinto with No. 40 I-steel weldering systems; And it is radial to make each short beam I be concentric circles; Perforate makes each long girder also be the stretching, extension of concentric circles radially outward, and the upper surface of each long girder is positioned on the same horizontal plane with corresponding also the be welded long girder of ring flange of corresponding end that is fixedly connected of bolt on the ring flange of each short beam I; The length of this each long girder is 2-3 rice; Also all can be I-steel No. 40, in addition, the short beam II of the flanged dish in outer end that is welded respectively in the left and right sides in each long girder stage casing; And the center line of the short beam II on each adjacent in twos long girder is laid respectively on the same center line; Between the ring flange of the short beam II of each adjacent in twos long girder, all auxiliary girders of corresponding flanged dish of two ends are installed, are played reinforcement effect with bolt, make this welding with group to firm steel construction piece of carriage formation.
During use, select the long girder of 2 meters or 3 meters on construction ground according to the maximum gauge of installation last furnace shell, first with corresponding being connected of the long girder of octagon central frame and each; Connect the auxiliary girder between each adjacent in twos long girder again, after each position is connected firmly, this group is carried out the levelness centering to carriage; Centering is qualified can be organized rightly on this carriage to furnace shell, group is welded the right upright seam of furnace shell group with electrogas welding machine qualified furnace shell; The electro-gas (enclosed) welding of this detachable last furnace shell welding with group to carriage both as the furnace shell group to the time steel platform used; When also having guaranteed the electrogas welding machine welding and the distance on ground, the furnace shell group is to after finishing, this carriage recyclable repeated use; Both safe and reliable, save material again.
To carriage, reusable, labor and material saving has reduced construction cost with group in the electro-gas (enclosed) welding welding of detachable last furnace shell that the utility model proposes.
Combine accompanying drawing and embodiment that the electro-gas (enclosed) welding welding of the detachable last furnace shell that the utility model proposed is described further carriage with group at present.
Description of drawings
Fig. 1 is that the schematic top plan view of group to carriage used in the electro-gas (enclosed) welding welding of detachable last furnace shell that the utility model proposes.
Among Fig. 1: 1, central frame 2, short beam I 3, long girder 4, short beam II 5, auxiliary girder 6, ring flange.
The specific embodiment
As can be seen from Figure 1: a kind of electro-gas (enclosed) welding of detachable last furnace shell welding, is characterized in that carriage with group: the electro-gas (enclosed) welding welding of this detachable last furnace shell with group to carriage mainly by central frame 1, short beam I 2, long girder 3, short beam II 4 and auxiliary girder 5 compositions; This central frame 1 is regular polygon; And this central frame 1 can be the octagon framework, and this central frame 1 can form the short beam I 2 of the flanged dish 6 in outer end that is welded respectively in the middle part of the lateral surface on heart framework 1 each limit hereinto with No. 40 I-steel weldering systems; And it is radial to make each short beam I 2 be concentric circles; Perforate makes each long girder 3 also be the stretching, extension of concentric circles radially outward, and the upper surface of each long girder 3 is positioned on the same horizontal plane with corresponding also the be welded long girder 3 of ring flange 6 of corresponding end that is fixedly connected of bolt on the ring flange 6 of each short beam I 2; The length of this each long girder 3 is 2-3 rice; Also all can be I-steel No. 40, in addition, the short beam II 4 of the flanged dish 6 in outer end that is welded respectively in the left and right sides in each long girder 3 stage casing; And the center line of the short beam II 4 on each adjacent in twos long girder 3 is laid respectively on the same center line; The auxiliary girder 5 of all corresponding flanged dish 6 in two ends is installed with bolt between the ring flange 6 of the short beam II 4 of each adjacent in twos long girder 3, is played reinforcement effect, make this welding with group to firm steel construction piece of carriage formation.
