Description

The device that connects two parts of boiler

The present invention relates to a kind of device that connects two parts of boiler.

Or rather, it relates to and a kind ofly connects a main siege and be connected the flue at top by a pipeline that is arranged between two parts, and a wall that calls the first of first wall is connected to the device of the wall of the second portion that calls second wall.

In two parts boiler, that is to say that boiler has a main siege and a rear portion flue that is connected the top by a pipeline, two-part one of them, siege normally, it leads to building, and another part is fixed in the first in a kind of mode that overhangs by a pipeline that connects them.

When boiler may be subjected to horizontal loading, when for example earthquake, wind-force, bottom effect, consider because the relative displacement that the two-part thermal expansion of boiler causes just needs to strengthen overhanging connection with firm flue.

Strengthen the join domain between siege and the flue, that is to say pipeline, this itself is known.But this situation at large-sized boiler is difficult.

Self-locking device (plunger type) also is placed between two parts.But this system can only be used under the situation of impermanency dynamic load, and it costs an arm and a leg and be easy to and blocks.

The invention provides a kind of simple and reliable mechanical connecting device that is used for quiet or dynamic load are delivered to from a part of boiler another part.

According to the present invention, it has at least one to be hinged on the connecting rod at two ends, its articulation, be called first articulation, be connected to fixed form on first of first wall, another articulation that is called second end, with vertically slidably mode be connected on second wall, connecting rod additionally is connected in the vertical fixing mode on second of first wall.

Therefore, external force is delivered on second wall through connecting rod from first wall, and its motion is arranged by first wall, and its thermal expansion is controlled and is uniform.Because thermal expansion, the transmission of external force thereby with antagonism mutually of relative displacement.

Distance between first and second is determined, so that the horizontal displacement that the vertical displacement that produces owing to differential expansion and connecting rod inclination angle is produced is consistent with respect to the relative displacement of first with second portion.

Second articulation preferably by have an intermediate that is slidably mounted in the column on the wall with vertically slidably mode be connected on second wall.

In first embodiment, connecting rod is connected in the vertical fixing mode by the intermediate with a crossbeam on second of first wall, and this crossbeam is connected on be fixed on first wall on the described column and in the vertical fixing mode described second.

In second embodiment, connecting rod is connected in the vertical fixing mode by the intermediate with a second connecting rod on second of first wall, and first end of this second connecting rod is hinged on the connecting rod, and second end is hinged on second of described fixing first wall.

In the case, first end of second connecting rod can be hinged on second articulation.

First articulation advantageously is fixed on to be connected on described first column of first wall.

The device multiple arrangement that is arranged between the first wall and second wall by mentioned earlier that connects two parts of boiler constitutes.

For a more detailed description to the present invention by accompanying drawing hereinafter, every width of cloth accompanying drawing is represented a preferred embodiment of the present invention.

Fig. 1 is the front view of two parts boiler.

Fig. 2 is the front view of first embodiment of a jockey of the present invention.

The partial enlarged drawing of Fig. 3 presentation graphs 2.

Fig. 4 is the front view of second embodiment of a jockey of the present invention.

Fig. 5 is the similar figure of a different embodiment.

Two parts boiler shown in Fig. 1 is connected a rear portion flue 2 by a pipeline 3 at the top and constitutes with one by a main siege 1.In a kind of known mode own, siege 1 is by the guiding of the sliding connector (not shown) on a support of buildings, and flue 2 is fixed on the siege 1 in a kind of mode that overhangs.

Consider horizontal external, reinforced structure itself is known on the level of pipeline 3, but this method is not suitable for the big large-sized boiler of exerting oneself.

According to the present invention, jockey is installed in zone 4, and is connected on the wall 1A and the wall 2A in the face of the flue 2 of 1A of siege 1.

In first embodiment shown in Figure 2, this jockey comprises that at least one is hinged and become angle α incline link 10 with horizontal plane at two ends.

One of articulation 10A is called first articulation, and it is connected on first P of first wall 1A with fixed form.Be fixed on the column 11 of P place connection first wall 1A at this end first articulation 10A.Except a P, column 11 can vertically slide on slide bar 12A, 12B.It leans against bar 13A, the 13B that is used for reinforced wall 1A.

Another articulation 10B that is called second end with vertically slidably mode be connected on the second wall 2A.This end is connected to by

middle body rod

15A, 15B and is slidably mounted on the column 14 on the wall 2A, and it leans against the bar 16 that is used to strengthen the second wall 2A.

Connecting rod 10 additionally is connected on second Q of first wall 1A in the vertical fixing mode.At this end, the crossbeam 17 that is connected to column 14 is connected to the some Q place of first wall 1A in the mode of vertical fixing.

Column

11,14 is advantageously connected by a plurality of similar connecting

rods

10,20, with the stability of structure that increases so obtain, and the most surfaces of

wall

1A, 2A is connected.

Fig. 3 has represented connecting rod 10 in more detail, suppose that wall 1A fixes, and column 14 is horizontally fixed on the wall 2A, when column 14 has moved displacement y, connecting rod 10 rotates around its articulation 10A, and its second articulation has moved vertical displacement delta y and its horizontal displacement Δ x less than Δ y.Column 14 is vertical slide displacement Δ y on wall 2A, therefore it is enough to selecting the distance between angle α and first P and second Q, so that make the wall 1A expansion Δ y amount between these points, so that obtained displacement x is consistent with the horizontal extension amount of pipeline 3.

Therefore connecting rod 10 is rigidly connected on wall 1A, the 2A, but allowing these walls has different expansion amount, and the horizontal displacement of generation and these expansions dynamically are consistent.

Fig. 4 represents another embodiment of jockey.

This jockey comprises that at least one is hinged and with angle [alpha] incline link 10 at two ends.

One of articulation 10A is called first articulation, and it is connected on first P of first wall 1A with fixed form.For example, be fixed to the bar 13A that is used for reinforced wall 1A at this end first articulation 10A.

Another articulation 10B that is called second end is connected on the second wall 2A in the mode that can vertically slide.This end is slidably connected on the column 14, and column 14 is at a connecting wall 2A of 15C place and can slide on bar 15A, the 15B on the wall 2A.

Connecting rod 10 also is connected on second Q of first wall 1A in the vertical fixing mode.Be hinged at the first end 30A of this end second connecting rod 30 on the second articulation 10B of connecting rod 10, its second end is hinged on second fixing Q of first wall 1A by middle body rod 13B.

Be convenient guiding, articulation 10B is columniform easily joint in being connected to the vertical slotted eye of column 14 with 30A.

Wall

1A, 2A by many categories like or the

symmetry connecting rod

10,20,30,40 advantageously connect.

Scheme shown in Figure 5 is different from the embodiment part of front, only is that the first end 30A of second connecting rod 30 is hinged on the point of connecting rod 10, but not on the articulation 10B.As a result, because the effect of successively decreasing, the distance between some P and the some Q diminishes, and the therefore miniaturization more of this device.
