Accompanying drawing explanation
Fig. 1 is the top view that the present invention has lifted rear broadening platform and indirect cool tower tower body X post;
In figure, 1 is the broadening platform of internode unit, and 2 is the broadening platform of the outer unit of internode.
Detailed description of the invention
Below in conjunction with drawings and Examples, the present invention is further described.
As shown in Figure 1, indirect air cooling system broadening platform combination lifting mounting method of the present invention, comprises the following steps:
Preparation before lifting: assemble the broadening platform 1 of multiple internode unit and the broadening platform 2 of the outer unit of multiple internode, fix bearing diagonal in broadening platform 1 bottom of internode unit, the lower end of bearing diagonal is unsettled;
The position of corresponding indirect cool tower tower body X post, starts the broadening platform 1 lifting internode unit, and between the broadening platform 1 and bearing diagonal of internode unit suspension hoisting device, lifting appliance tangles the unsettled lower end of bearing diagonal;
The broadening platform 1 of internode unit is lifted to installed height mark, after broadening platform 1 gradient of adjustment internode unit, the broadening platform 1 of internode unit is welded with indirect cool tower tower body X post first built-in fitting;
By lifting appliance adjustment bearing diagonal angle, welded by bearing diagonal with indirect cool tower tower body X post second built-in fitting, the broadening platform 1 completing internode unit lifts to be installed;
Repeat above-mentioned steps, the broadening platform 1 of all internode unit is installed along the lifting in peripheral a week of indirect cool tower tower body;
Position between adjacent two the X posts of corresponding indirect cool tower tower body, utilizes the mode identical with the broadening platform of lifting internode unit to lift the broadening platform of the outer unit of internode, until the broadening platform 2 of the outer unit of internode has all lifted;
The broadening platform 2 of outer to the broadening platform 1 of unit between adjacent segments and internode unit is welded and fixed mutually.
The step of the broadening platform 1 of assembling internode unit is:
According to the distance between the broadening platform radial girders of the spacing determination internode unit of the upper end open of indirect cool tower tower body X post, the spacing of the broadening platform radial girders of internode unit is equal with the spacing of the upper end open of indirect cool tower tower body X post.Then the radial girders of the broadening platform of internode unit, hoop beam and ring secondary beam are assembled by designing requirement, form the broadening platform framework of internode unit; In the broadening platform framework inside of internode unit, some purlins are installed, complete the assembling of the broadening platform of internode unit.
The assembling process of broadening platform 2 of the outer unit of internode is identical with the assembling process of the broadening platform of internode unit.
Detailed process is installed in the lifting of indirect air cooling system broadening platform combination:
(the broadening platform of internode unit corresponds to the position of indirect cool tower tower body X post during assembling, the broadening platform of unit outside the broadening platform of internode unit and internode to be combined into entirety respectively, the broadening platform of the outer unit of internode corresponds to the position between indirect cool tower tower body X post), use interim hinge to be fixed on the broadening platform of internode unit by bearing diagonal at broadening platform away from tower body side, use float to be transported to the lifting work starting broadening platform outside indirect cool tower.
70t crawler crane is used in lifting, first lift the broadening platform 1 of internode unit, two 2t chain blocks are hung with tower body weld side two ends flat 1 of the broadening of internode unit, the chain block other end tangles bearing diagonal lower end simultaneously, adjustment bearing diagonal angle is consistent with setting angle, when the soft cat ladder of suspension simultaneously two cover welds for bearing diagonal; After crane works broadening platform 1 installed height mark rising to internode unit, use the broadening platform gradient of level gauge adjustment internode unit, absolute altitude consistent with installation requirement, prevent cooling triangle lifting absolute altitude from occurring deviation, then weld inside the broadening platform of internode unit with tower body X post built-in fitting.
By 2 2t chain block adjustment bearing diagonal angles, qualified rear and tower body X post slugging, has welded rear excision suspender.With the broadening platform 2 of the outer unit of same method lifting internode, until whole broadening platform has all lifted.After having been lifted by the broadening platform 2 of outer for internode unit, be welded and fixed mutually by the broadening platform 2 of outer to the broadening platform 1 of unit between adjacent segments and internode unit, now, whole broadening platform is around being arranged on indirect cool tower tower body peripheral one week.
Meanwhile, the present invention reaffirmed that before broadening platform hangs bearing diagonal is correctly installed firmly, can not landing.After broadening platform and bearing diagonal welding, interim hanging apparatus need be removed.
By reference to the accompanying drawings the specific embodiment of the present invention is described although above-mentioned; but not limiting the scope of the invention; one of ordinary skill in the art should be understood that; on the basis of technical scheme of the present invention, those skilled in the art do not need to pay various amendment or distortion that creative work can make still within protection scope of the present invention.
