Detailed description of the invention
Below in conjunction with drawings and Examples, the present invention is described in further detail.
See Fig. 1, Fig. 2, Fig. 3, permanent horizontal tray combined member of the present invention, for installing tower tray 5 in tower tray tower 7, and selects different material weldings shaping according to process condition difference; It comprises the bow beam 1 that two ends are welded with tower tray tower 7 inwall, bow beam 1 for bearing the quality of tower tray 5 and technological operation medium, for the benefit of load-bearing, the middle part of bow beam 1 raises up, and two ends lay respectively at the two ends of certain horizontal diameter in tower; For improving the bearing capacity of bow beam 1, should, according to different tower internal diameters, be 10 ° ~ 30 ° designs by circular arc tangential line angle θ protruding in the middle part of bow beam.As seen from Figure 1, the upper/lower terminal of vertical links 4 is connected with the lower surface center of bow beam 1 and the upper surface center of tower tray 5 respectively, and the upper/lower terminal of connecting rod 4 respectively welds a spheroid.
As seen from Figure 1, bow beam 1 lower surface center and tower tray upper surface center are fixed with a hook base 2 respectively, and each hook base 2 is connected with a spherical flap hook 3, and the spherical gap between two ends cooperation of connecting rod 4 is installed in two spherical flaps hooks 3.Composition graphs 4, spherical flap hook 3 be less than one spherical but be greater than half spherical, like this, the spherical two ends being convenient to connecting rod 4 are installed on unlikely in two spherical flaps hooks 3 dropping out.See Fig. 2, Fig. 3, Fig. 4, Fig. 5, Fig. 6, each hook base 2 comprises four hook plates 201 (layout of the hook plate on tower tray 5 and the same on bow beam 1 shown in Fig. 2, Fig. 3, do not draw separately) be symmetrically welded in bow beam 1 lower surface center or tower tray 5 upper surface center; Visible from Fig. 4 to Fig. 6, each spherical flap hook 3 is made up of two identical spherical lobes 302, and the outer surface of each spherical lobe 302 is provided with two braces 301 corresponding with hook plate 201, hook plate 201 is flexibly connected with bearing pin by pin-and-hole with brace 301 one to one; Equatorial plane place corresponding to two spherical lobe 302 both sides is respectively provided with a connecting plate 303, and two connecting plates 303 of homonymy are bolted (in figure, bolt does not draw); The relative middle diametric plane in two spherical lobe 302 equatorial plane places is provided with limiting plate 304, and the effect of limiting plate 304 is, when preventing spherical lobe 302 bolts locked, and spherical flap hook 3 and connecting rod 4 excessive occlusal.
See Fig. 1, Fig. 7, Fig. 8, between the inwall of tower tray 5 and tower tray tower 7, be provided with the seal disc 6 of annular; Seal disc 6 is welded on tower body inwall, the arc surface that the medial surface of seal disc 6 is one is the center of circle with tower tray 5 central point, the radius R of this arc surface is a bit larger tham the radius of tower tray 5, the arc surface of seal disc 6 medial surface and tower tray 5 outer surface is made to be the matched in clearance of 0.2-0.5mm, thus guarantee in tower body vibration processes, the freely-movable of tower tray 5 and and seal disc 6 between maintain constant gap (being unlikely to occur a large amount of leakage).The height h1 of seal disc 6 then should not be less than the tilt value of tower body tower tray 5 outer rim under allowable angle of inclination θ 1 (inclination angle during maximum defluxion appears in tower body).Simultaneously for avoiding inertia motion unnecessary in tower tray 5 deflection, the upper and lower surface of seal disc 6 is along the circumferential direction respectively evenly equipped with three pieces of baffle plates 601, be connected with screw between baffle plate 601 with seal disc 6, for rotating in a circumferential direction of defining baffle 601, baffle plate 601 should be arranged in the groove that seal disc 6 holds successfully in advance.
For ensureing that tower tray works in the best condition, should make connecting rod 4 axis, tower tray 5 center line and tower tray tower 7 dead in line, tower tray 5 selects existing tower tray according to process condition difference; Simultaneously for ease of unit check maintenance, permanent horizontal tray combined member total height h of the present invention is unsuitable excessive.
