Detailed description of the invention
Technical scheme of the present invention is described in detail referring to accompanying drawing.
As shown in Figure 1, 2,1 is main structure body, 9 is long-span roofing, first the reserved lifting hole when the concrete roof structure construction need installing crane, to install interim boist truss beam 2 and lifting beam 3, being provided with hydraulic synchronizing lifting system 4 above lifting beam 3, promoting and direction for controlling, hydraulic synchronizing lifting system 4 connects suspender 5 by steel strand 10 through lifting beam 3.
Then to hydraulic synchronizing lifting system 4 detect qualified after debug, as examination promote, counterweight balance and static test, the qualified rear formal lifting of comfirmation test.
Shown in Fig. 3, Fig. 4, the crane that mounted crane runway 7 can be used for being about to install in advance slides, before installation crane, need two panels main beam of crane 6 is first installed, wherein respectively there is a pulley 17 at main beam of crane 6 two ends, and are provided with main beam of crane track 15 in main beam of crane 6, as shown in Figure 8.First wherein a slice main beam of crane 6 being transported to promotes immediately below suspension centre 8, wherein a slice main beam of crane 6 is promoted by above-mentioned suspender 5, in lifting process, the angles of the whole main beam of crane in the lifting of described main beam of crane 6 is adjusted by the cable wind rope 12 of bottom, main beam of crane 6 two ends and the guideline 13 on top, two ends, its angles and crane runway 7 is made to there is certain deviation, the span of main beam of crane 6 is made to be less than span between crane runway 7, guarantee that main beam of crane 6 can not encounter perimeter body structure in lifting process, two does not have obstacle.
Shown in Fig. 5 and Fig. 6, described main beam of crane 6 shifts out lifting region, when being promoted to a little more than crane runway 7, control it by hydraulic synchronizing lifting system 4 and suspend lifting, and adjust the direction of main beam of crane 6, make its angles vertical with crane runway 7, and pulley 17 line of centers at main beam of crane 6 two ends overlaps with crane runway 7 line of centers, then main beam of crane 6 is slowly fallen to being placed on crane runway 7, the pulley 17 of main beam of crane 6 is placed in crane runway 7 slidably, namely installs a slice main beam of crane.Another sheet main beam of crane 6 is installed in the same way again, makes the installing space of two panels main beam of crane 6 on crane runway 7 be greater than vehicle-width.
Again see shown in Fig. 7 and Fig. 8, after above-mentioned two panels main beam of crane 6 is located in crane runway 7, the installation of crane 14 can be carried out, crane 14 is promoted by hydraulic synchronizing lifting system 4, after the main beam of crane track 15 that described crane 14 is promoted to a little more than above-mentioned main beam of crane 6, two panels main beam of crane 6 is closed up connection, and adjust the position of main beam of crane 6, be located at immediately below crane 14, then by crane 14 slowly under be put on main beam of crane track 15, complete lifting.
After such crane installs, can slide along main beam of crane track 15 on main beam of crane 6, main beam of crane 6 can carry out the slip with main beam of crane track 15 vertical direction on crane runway 7 simultaneously, and namely crane can slide as required at four corners of the world four direction.
Preferably, plain thrust bearing 11 is installed bottom hydraulic synchronizing lifting system 4, more effectively can adjusts the direction promoting thing.
Preferably, promote suspension centre 8 and be positioned at the inclined 20cm place of main beam of crane mid point.
Preferably, when main beam of crane 6 is promoted to higher than crane runway 7 about 100mm, suspends and promote with the direction adjusting main beam of crane 6.
Preferably, when crane 14 is promoted to higher than main beam of crane track 15 absolute altitude 100mm, both sides main beam of crane 6 is closed up connection.
Preferably, main beam of crane 6 is single-point lifting, and crane 14 is that two point promotes.
Although Indoor non-standard crane installation method of the present invention is described with reference to current instantiation, but those skilled in the art should be realized that, above example is only used to the present invention is described, change and the amendment that also can make various equivalence when not departing from spirit of the present invention all will drop in the scope of claims of the present invention.
