Description
Technical Field
The utility model relates to an end connection structure especially relates to a be suitable for connection structure between msw incineration exhaust-heat boiler's the tube wall, belongs to the boiler supporting member field.
Background
In the boiler support structure, the reinforcing member is provided to increase the rigidity of the furnace tube panels and prevent the tube panels from being damaged by internal or external pressure, and is classified into two types of horizontal or vertical reinforcing members.
In a waste incineration waste heat boiler, smoke can pass through a tail part cladding hot surface, the cladding pipe wall structure is in a inconsistent expansion value due to the overall system arrangement requirement, a furnace top pipe and a furnace side wall are generally not fixedly connected, and adjacent pipe walls 1 and 4 are not connected as shown by a mark a (gap) in figure 1.
In the prior art, a horizontal reinforcing part is only arranged in a tail coating area of the waste incineration waste heat boiler, or a small number of vertical reinforcing parts exist, but the end part of the waste incineration waste heat boiler is only connected with an upper header and a lower header of a side wall to form a connecting structure, load acts on pipe walls which are not fixedly connected at two ends of the pipe walls and cannot be effectively transmitted, and after the boiler operates, heat insulation materials in the area crack, so that the design requirements cannot be met.
Disclosure of Invention
The to-be-solved technical problem of the utility model is how to make can effective connection between the pipe wall.
In order to solve the technical problem, the technical scheme of the utility model is to provide an end connection structure, which is characterized by comprising at least 2 steel plate gaskets, wherein the bottom surfaces of the steel plate gaskets are connected with a transverse pipe wall, and transverse steel plates are arranged on the steel plate gaskets; a vertical steel plate is arranged on the transverse steel plate, and a pulling plate is arranged on the vertical steel plate; one end of the pulling plate is fixedly connected with the vertical steel plate, and the other end of the pulling plate is connected with one end of the movable hinge; the movable hinge is arranged above the coating upper header, and the other end of the movable hinge strides over the coating upper header and is connected with a steel plate; the bottom of the steel plate is fixedly connected with a vertical reinforcing piece fixed on the vertical pipe wall.
Preferably, the number of the steel plate gaskets is at least 2.
Preferably, the movable hinge comprises a pair of connecting plates arranged at the upper side and the lower side of the pull plate and the steel plate, and two ends of each connecting plate are respectively connected with the pull plate and the steel plate through rotatable pin shafts.
The utility model is suitable for a there is not effective fixed connection's scene when pipe wall one end or both ends and adjacent pipe wall, the utility model has the advantages of:
1. the structure is simple, and the process difficulty is low;
2. the load transmission between the two pipe walls is realized, the movable connection is realized, and the thermal expansion difference between the two pipe walls is absorbed.

Fig. 1 is a connection schematic diagram of an end connection structure provided in this embodiment;
fig. 2 is a schematic connection position relationship diagram of an end connection structure provided in this embodiment;
fig. 3 is a schematic structural diagram of an end connection structure according to this embodiment;
fig. 1 is a schematic diagram showing the relationship between the connecting structure and the transverse pipe wall and the vertical pipe wall, and shows that the two pipe walls are not connected and a gap a exists; the relationship of the connection structure to the transverse pipe wall, the cladding header, the vertical pipe wall and the vertical reinforcement is shown in fig. 2.
Detailed Description
In order to make the present invention more comprehensible, preferred embodiments are described in detail below with reference to the accompanying drawings.
Example 1
As shown in fig. 1, the end connection structure 2 provided in this embodiment connects a horizontal pipe wall 1 and a vertical pipe wall 4, and a gap is left between the two pipe walls.
As shown in figure 2, one end of the end connecting structure 2 is connected with the transverse pipe wall 1, and the other end of the end connecting structure strides over the covering upper header 3 and is connected with the vertical pipe wall 4 through the vertical reinforcing piece 5, so that load transmission between the two pipe walls is realized, and meanwhile, the movable connection is realized, and the thermal expansion difference between the two pipe walls is absorbed.
As shown in fig. 3, 12 steel plate gaskets 7 are connected to the horizontal pipe wall 1, one side of the horizontal steel plate 6 is connected to the steel plate gasket 7, the other side is connected to the vertical steel plate 8, the vertical steel plate 8 is vertically placed, the upper side of the vertical steel plate is connected to the pulling plate 9, and the pulling plate 9 is connected to the steel plate 12 welded to the vertical reinforcement 5 through a movable hinge formed by a pair of connecting plates 10 and a pin 11.
Consider waste incineration exhaust-heat boiler afterbody cladding structure characteristics, as shown in fig. 2, in boiler afterbody cladding region, perpendicular reinforcement 5 has been arranged to 2 one end of end connection structure, and this perpendicular reinforcement 5 is connected with vertical tube wall 4, and the other end is walked around cladding header 3, directly is connected with horizontal tube wall 1, forms the connection of vertical tube wall 4 and horizontal tube wall 1, and the transmission of the power of this department is: the force is transmitted to the vertical reinforcing member 5, namely to the end connecting structure 2, and then to the adjacent pipe walls, and meanwhile, the difference in thermal expansion between the adjacent pipe walls is absorbed by arranging the movable hinges in consideration of the difference in expansion direction and value between the adjacent pipe walls.
Example 2
The number of the steel plate spacers 7 was 2, and the rest was the same as in example 1.
