Abstract
The utility model provides a strap reinforcing beam which comprises horizontal beams and a balance rod arranged between the horizontal beams, and is characterized in that the horizontal beams are connected with an inner strap through reinforcing beam supports, the end parts of the horizontal beams are connected with the end parts of the inner strap through corner devices. The strap reinforcing beam has the advantages that: a water cooling wall tube wall is ensured not to have great bending and deformation; and the inner furnace pressure load applied on the horizontal beams are offset.
Description
Technical field
The utility model relates to a kind of spirally-wound type buckstay, is usually used in boiler vertical tube wall, belongs to spirally-wound type buckstay technical field.
Background technology
Buckstay can be divided into two kinds of spirally-wound type buckstay and grid type buckstays.The spirally-wound type buckstay mainly is made of horizontal gird, is usually used in the vertical tube wall.And the grid type buckstay is made up of horizontal beam and vertical beam, is usually used in oblique furnace bottom and helix tube wall.The main effect of buckstay has:
1) prevent owing to operation negative pressure in the furnace puff malleation, stove, give/factors such as air-introduced machine emergency stop valve trip cause that furnace pressure changes to damage and are subjected to the pressure pipe wall; Prevent that the pulsation of burning concussion and flue gas pressures from causing that the furnace wall low-frequency vibration causes the additional low frequency flexural fatigue of pipe wall coil and reduces pipe service life;
2) set up boiler bulk expansion center.Set up dead point mechanism and compensation arrangement, the regular expansion of direction that pipe wall each position is determined by design avoids freely not producing because of expanding the additional stress drawing crack pipe wall that transfinites, and influences safe operation;
3) set up outer load and transmit guiding in order.The open-air boiler of arranging can correctly be delivered on the steelframe by the guiding node by the load that pipeline and other annexes applied around wind-force, seismic force, the body.All the pipe walls of suspention are provided with reasonable direction and supporting arrangement, keep balance not have and rock, and expand smooth and easyly not to be obstructed.
But because structural restriction, the spirally-wound type buckstay exists the water screen tube wall that big diastrophic shortcoming takes place easily at present.
The utility model content
The purpose of this utility model provides the on-deformable spirally-wound type buckstay of a kind of water screen tube wall.
In order to achieve the above object, the technical solution of the utility model has provided a kind of spirally-wound type buckstay, comprise horizontal gird, between horizontal gird, be provided with balancing pole, it is characterized in that, horizontal gird is connected with interior bandage by the buckstay bearing, and the end of horizontal gird is connected with interior strap end by the bight device.
The buckstay bearing is a U-shaped steel plate, and the welding of its opening one end and horizontal gird is fixing, and the other end is close to interior bandage but is not welded extremely so that can slide relatively between the two during the boiler expanded by heating.Thereby two relative up and down interior bandage and U-shaped steel plate are stuck in the weight of bearing buckstay on the water-cooling wall simultaneously and transmit boiler loading of L shaped steel plate.Horizontal gird is bent by the effect of furnace pressure load, thereby has guaranteed that by limiting its amount of deflection the water screen tube wall too big flexural deformation can not take place; The end of horizontal gird link to each other with interior bandage on the adjacent water-cooling wall by the bight device in case the uniform load that horizontal gird is suffered change in the axial compressive force/pulling force of bandage.Because the suffered furnace pressure load of the horizontal gird at horizontal gird and its back side is equal and opposite in direction all the time, direction is opposite, just can offset this load so these two horizontal girds are linked to each other with the bight device by interior bandage.
This shows, the utility model has the advantages that: can satisfy the boiler expansion requirement; Guaranteed that the water screen tube wall too big flexural deformation can not take place; Offset the suffered furnace pressure load of horizontal gird.

The specific embodiment
Specify the utility model below in conjunction with embodiment.
Embodiment
As shown in Figure 1, the structural representation of a kind of spirally-wound type buckstay that provides for the utility model is made up of horizontal gird 1, buckstay bearing 2, bight device 4 and balancing pole 5.
Shown in Fig. 2 A and Fig. 2 B, be the connection diagram of horizontal gird 1 by buckstay bearing 2 and interior bandage 3, wherein buckstay bearing 2 is made up of a U-shaped steel plate 21 and two blocks of L shaped steel plates 22.The both sides of U-shaped steel plate 21 openings and the welding of the edge of a wing of horizontal gird 1 are fixing, and its 3rd limit and interior bandage 3 are close to but are not welded.Be arranged in the U-shaped steel plate and fix the 3rd limit of bandage 3 and U-shaped steel plate 21 in another side blocks up and down relatively with the water-cooling wall welding in two L shaped steel plates 22 one side of both sides about in the of 21.Leaving certain interval between L shaped steel plate 22 and interior bandage 3 and the U-shaped steel plate 21 relatively moves to allow it.
Shown in Fig. 3 A and Fig. 3 B, be the connection diagram of interior bandage 3 by bight device 4 and water-cooling wall, bight device 4 is made up of four gussets 41 and two link 42, one group in twos of four gusset 41, cross staggered respectively with two walls of water-cooling wall on 3 welding of interior bandage fix.Horizontal gird 1 end need be cut to hold bight device 4.Perforate respectively on the web of gusset 41 and horizontal gird 1.Wherein align with interior bandage 3 on the adjacent water-cooling wall respectively in the hole on the gusset 41, and the pre-certain distance partially in the hole on hole on the horizontal gird 1 and the gusset 41 is to satisfy the expansion displacement of water-cooling wall and horizontal gird 1.Thereby two links 42 couple together realizable force by the conduction of horizontal gird 1 to interior bandage 3 with horizontal gird 1 and gusset 41 respectively.Each links 42 44, four packing rings that are connected with bearing pin 45 of 43, two columnar pin shafts of connecting plate that are welded by three block plates again, and the pad 46 of two block weldings on the horizontal gird web formed.Connecting plate 43 1 ends are clamped the web of horizontal gird 1, and are connected with horizontal gird 1 by bearing pin 44; Thereby its other end upper and lower sides is respectively arranged a gusset 41 and is also connected by bearing pin 44 and realizes being connected of horizontal girds 1 and interior bandage 3.
