Abstract
The utility model provides an angle wrapping structure of vertical outer protecting plates at the boiler wall of a boiler, which comprises an angle wrapping plate, and is characterized in that both sides of the angle wrapping plate are respectively connected with the edges of a first outer protecting plate and a second outer protecting plate by a displacement device. The utility model has the advantages that the problem of deformation of the angle wrapping plate of the outer protecting plates when the boiler is started or stopped in running is solved, so that the uniformity of the appearance is kept during the hot state and the cold state of the outer protecting plates at the boiler wall of the boiler; and the problems of unevenness because of the expansion of the outer protecting plates and easy large rupture during repeated running are solved, and the maintenance cost of the angle wrapping plate of the outer protecting plates is reduced.
Description
Technical field
The utility model relates to the vertical outer casing cornerite of a kind of boiler setting structure.
Background technology
In present boiler setting, the burner hearth all around outer casing syndeton on the corner of four sides wall uses a block plate to connect usually.The outer casing of both sides forms a right angle, does not connect each other.Be bent into the L type with a metallic plate, the both sides of L type are fastenedly connected with screw with the outer casing on both sides respectively.When boiler was worked, the outer casing of furnace wall expanded along with the expansion of water-cooling wall, and the distance between the outer casing of both walls strengthens, and the right angle of cornerite plate during by cold conditions is drawn as the obtuse angle.
In the discovery in service of reality, the cornerite plate is stretched when hot, is taken back original state during cold conditions.Because the absorption to boiler expansion is to realize by dull and stereotyped distortion own.When the change of expanding was big, the situation of drawing crack can appear in the cornerite plate.Boiler repeatedly blowing out rise in the stove process, the cornerite plate be difficult to restore to the original state, plastic deformation repeatedly also is easy to cause the fracture of cornerite plate.
Summary of the invention
The purpose of this utility model provides a kind of outer casing cornerite structure of not easy fracture.
In order to achieve the above object, the technical solution of the utility model has provided the vertical outer casing cornerite of a kind of boiler setting structure, comprise the cornerite plate, it is characterized in that the both sides of cornerite plate connect the edge of first outer casing and second outer casing respectively by gearshift.
Further, described gearshift comprises connecting plate, and an end of connecting plate links to each other with first outer casing or with second outer casing by first locating shaft, and the other end links to each other with described cornerite plate by second locating shaft.
Described gearshift comprises that frid is located on described first outer casing or is located on described second outer casing, is provided with connecting plate on the cornerite plate, and connecting plate inserts in the frid.
The utility model has the advantages that: solved the problem of outer casing cornerite plate distortion when boiler start/ stop moves, outward appearance is consistent when making the hot and cold conditions of boiler setting outer casing; Solved because of outer casing expands not freely, the problem of easy major rupture when moving has repeatedly reduced the cost of outer casing cornerite plate maintenance.

The specific embodiment
Specify the utility model below in conjunction with embodiment.
Embodiment 1
As shown in Figures 1 and 2, for the vertical outer casing cornerite of a kind of boiler setting structure that the utility model provides, form by cornerite plate 3, connecting plate 4 and three parts of locating shaft.Have the hole below reaching above the connecting plate 4, the hole that first locating shaft 5 passes connecting plate 4 tops is connected with first outer casing 1, and connecting plate 4 can be around first locating shaft 5 with respect to 1 rotation of first outer casing.The hole of passing connecting plate 4 belows with one second locating shaft is connected with cornerite plate 3 again, and same connecting plate 4 can be around second locating shaft with respect to 3 rotations of cornerite plate.Cornerite plate 3 is the metallic plate of V-type, its in addition on one side with the connected mode of second outer casing 2 connected mode with itself and first outer casing 1.After boiler furnace expanded, its duty as shown in Figure 3.
As Fig. 4 and shown in Figure 5,, form by cornerite plate 3, frid 7 and connecting plate 8 for the vertical outer casing cornerite of the another kind of boiler setting structure that the utility model provides.Frid 7 usefulness securing members are fastened on first outer casing 1, connecting plate 8 usefulness securing members are connected on the cornerite plate 3, connecting plate 8 inserts in the frid 7, the connection of Xing Chenging like this, both can make the weight of cornerite plate 3 pass to first outer casing 1, and can allow again be slidingly connected between the cornerite plate 3 and first outer casing 1 by connecting plate 8 and frid 7.The connected mode of the cornerite plate 3 and second outer casing 2 is with the connected mode of the cornerite plate 3 and first outer casing 1.
Claims (3)
