Embodiment 1

[0028] figure 1 It is the basic type of the present invention. exist figure 2 In the embodiment, the bolt 2, the anti-sway pressure-bearing end plate 3a, and the polytetrafluoroethylene anti-sway and resistance-reducing end plate 3b together form a "bolt-type pressure bar", which has the "slide rail" function of a traditional anti-sway device, in which the bolt 2 It is welded to the anti-sway pressure end plate 3a, and the polytetrafluoroethylene anti-sway resistance end plate 3b is fixed on the anti-sway pressure end plate 3a. It has high compressive strength, smooth surface and small friction coefficient, which can reduce the vertical sliding resistance. The anti-sway pressure-bearing guide steel plate 7 is fixed on the outer cylinder wall 8, and is vertically parallel to the anti-sway pressure-bearing end plate 3a, and is used to transmit the horizontal force of the "bolt type pressure rod" to the outer cylinder wall 8. At the same time, " The polytetrafluoroethylene an...

Embodiment 2

[0033] image 3 It is an expanded application type of the present invention. For use with steel platform beam chimneys or steel tower chimneys. The connecting steel plate 9 is welded on the platform steel beam 10, and the cylindrical nut 1 is fixed together with the platform steel beam 10. The bolt 2 can go deep into the interior of the platform steel beam 10 through the cylindrical nut 1 until it is close to the surface of the platform steel beam 10, and the maximum The requirement for the distance between the platform steel beam 10 and the inner cylinder is minimized, and the limitation of the platform size is reduced.

[0034] After the inner cylinder is installed, the bolt 2 is rotated to the surface of the stiffening ring 4 of the inner cylinder, and tightly attached to it, and the installation of the anti-sway device is completed.

[0035] Additional Notes: The platform steel beam 10 in the embodiment of the present invention is in the form of channel steel, and the cy...

Embodiment 3

[0037] Figure 4 It is another expanded application type of the present invention. It is mainly suitable for the situation where the inner and outer cylinders of the chimney have a large space, but it is not suitable, unsatisfactory or not equipped with an anti-sway platform, and it is especially suitable for the renovation project of the old chimney. Due to high-altitude construction, the construction errors of the wall thickness, radius, and roundness of the outer wall 8 of the chimney are generally large, and the actual size of the chimney section and the design drawings have a large error, which can easily cause the size of the anti-sway rod to fail to meet the actual installation. needs. By adopting the present invention, the dimensional error can be adjusted by enlarging the bolt length, which greatly improves the application range of this type of anti-sway device.

[0038] exist Figure 4 In the embodiment, the cylindrical nut 1 is fixed on the outer cylinder wall 8 ...

Abstract

The invention relates to a micro-space chimney shaking-stopping device, and belongs to the technical field of chimney design and construction. The micro-space chimney shaking-stopping device is arranged between a smoke exhaust inner barrel and an outer barrel wall of a sleeve type chimney, the micro-space chimney shaking-stopping device comprises a cylindrical nut, a bolt, a shaking-stopping pressure-bearing end plate and a shaking-stopping resistance-reducing end plate, the bolt with adjustable length is arranged in the cylindrical nut, one end of the bolt is provided with the shake-stoppingpressure-bearing end plate and the shake-stopping resistance-reducing end plate, the cylindrical nut can be fixed on the inner barrel, an outer barrel or a platform beam, the shortest extending stateof a screw rod is kept during hoisting of the inner barrel by adjusting the length of the bolt, and the inner barrel rotates and extends after being in place and is tightly attached to a shaking-stopping pressure-bearing guide steel plate, so that space limitation is reduced, and the shaking-stopping effect on the smoke exhaust barrel is achieved. According to the micro-space chimney shaking-stopping device, micro-space shaking-stopping is achieved, the requirement that a large-diameter smoke exhaust inner barrel can be arranged in a small space is met, the smoke flow speed and the chimney rain number are effectively reduced, and the environmental protection value and the economic value of chimney transformation are achieved.

Description

technical field [0001] The invention relates to a micro-space chimney anti-sway device, which belongs to the technical field of chimney design and construction. Background technique [0002] The telescopic chimney consists of a smoke exhaust inner tube (referred to as "inner tube") and an outer tube wall (referred to as "outer tube"). The inner cylinder is used to discharge the flue gas with corrosive effect; the sleeve chimney realizes two different types of loads or functions: directly bearing external loads such as wind and directly bearing the action of flue gas; Load or action, obtain functional division of labor, which is conducive to the structural safety of the outer cylinder and the inspection and maintenance of the inner cylinder. However, the inner cylinder of this type of chimney has low rigidity and large deformation, so it is necessary to install multiple layers of horizontal anti-sway devices along the height to restrain the horizontal displacement of the inn...
