Abstract
The utility model discloses an overall spiral winding staircase mechanism on the outside of a spherical tank, which comprises an oblique straight ladder, a slow-walking platform, a spiral winding staircase, an arc-shaped platform and a circular platform, wherein the two ends of the arc-shaped platform are provided with drill holes, one end of the arc-shaped platform is connected with a bolt on the circular platform through the drill hole, the other end of the arc-shaped platform is connected with a bolt on the spiral winding staircase through the drill hole, the circular platform and the arc-shaped platform are integrally connected so as to form a top platform of the spherical tank, and the other end of the spiral winding staircase is connected with the slow-walking platform. The overall mechanism disclosed by the utility model solves the problem that a spray pipe is smoothly arranged around the outer wall of the spherical tank; the circular platform and the arc-shaped platform are integrally connected, so that the overall mechanism is applicable, the working efficiency is enhanced, and the cost is reduced.
Description
Technical field
The utility model is a kind of winding stair mechanism, is specifically related to a kind of spiral winding staircase integrated model for spherical tank outside.
Background technology
At present, spherical tank ladder, the fabrication and installation of platform are comprised of circular platform and rectangular platform, be connected with spiral winding staircase again, rectangular platform in said structure can produce outstanding corner angle at the position being connected with spiral winding staircase, and rectangular platform length of the prior art is very short, cause cocke-stair to be installed near spherical tank outer wall, the installation site of the spray pipeline of spherical tank outer wall is subject to certain restrictions, cocke-stair assorted installation on spherical tank of prior art simultaneously, like this because constructor is in work high above the ground, the reliable degree of assorted cocke-stair declines, cause inefficiency, cost is high.
Summary of the invention
In order to make up the deficiencies in the prior art, the utility model provides the spiral winding staircase integrated model of a kind of spherical tank outside, solved the problem that shower is installed smoothly around spherical tank outer wall, and assorted and welded on the ground to spiral winding staircase integral body, integral hoisting is installed to spherical tank, increases work efficiency, reduces costs.
The utility model is achieved through the following technical solutions: the spiral winding staircase integrated model of spherical tank outside, comprise oblique vertical ladder, the platform of walking unhurriedly, also comprise spiral winding staircase, arc platform, circular platform, the two ends of described arc platform are provided with boring, one end of arc platform is connected with the bolt on circular platform by boring, the other end of arc platform is connected with the bolt on spiral winding staircase by boring, circular platform is connected with arc platform and forms spherical tank top platform, and the other end of spiral winding staircase connects the platform of walking unhurriedly.
Described arc platform consists of inner side angle steel, outboard angle, foot-operated flat board.
The external diameter angle of described arc platform is 45-55 degree, and internal diameter angle is 43--55 degree.
Described spiral winding staircase consists of interior plate, outer panel, foot rest.
The beneficial effects of the utility model: the utility model provides the spiral winding staircase integrated model of a kind of spherical tank outside, by introducing the structure of arc platform, and the length that has significantly extended arc platform, make the whole mechanism of spiral winding staircase and spherical tank outer wall have enough distances, can make shower be arranged on smoothly spherical tank outer wall and pass integrated model, while circular platform is connected with arc platform integral type, makes integrated model more applicable, increases work efficiency, reduces costs.
Accompanying drawing explanation
Fig. 1 is front view of the present utility model.
Fig. 2 is top view of the present utility model.
The specific embodiment
The spiral winding staircase integrated model of spherical tank outside, as shown in Fig. 1 to 2, comprise oblique vertical ladder 1, the platform 2 of walking unhurriedly, also comprise spiral winding staircase 3, arc platform 4, circular platform 5, described arc platform 4 is by inner side angle steel 8, outboard angle 9, foot-operated dull and stereotyped 10 form, the external diameter angle of arc platform 4 is 45-55 degree, internal diameter angle 43-55 degree, the two ends of arc platform 4 are provided with boring, one end of arc platform 4 is connected with the bolt 7a on circular platform 5 by boring 6a, spiral winding staircase 3 is by interior plate 11, outer panel 12, foot rest 13 forms, the other end of arc platform 4 is connected with the bolt 7b on spiral winding staircase 3 by boring 6b, circular platform 5 is connected with arc platform 4 and forms spherical tank top platform, the other end of spiral winding staircase 3 connects the platform 2 of walking unhurriedly.
In work, on ground, complete the assorted of arc platform 4 and circular platform 5 and welding, form an Integral ball tank top platform and be lifted on spherical tank and install; On ground, complete the assorted and welding to the interior plate 11 on spiral winding staircase 3, outer panel 12, foot rest 13, in the assorted process of spiral winding staircase 3, to guarantee that each assorted step size is accurate, start to lift one-piece auger winding staircase 3 on spherical tank, after first carrying out the bolt 7b of helical disk ladder 3 upper ends during lifting and boring 6b on arc platform 4 being connected, then carry out being connected of spiral winding staircase 3 bottoms and the platform 2 of walking unhurriedly.
