Detailed description of the invention
Below in conjunction with drawings and Examples, embodiments of the present invention are described in further detail。Following example are used for illustrating the present invention, but can not be used for limiting the scope of the present invention。
In describing the invention, it should be noted that, term " on ", D score, "left", "right", " top ", " end ", " interior ", the orientation of the instruction such as " outward " or position relationship be based on orientation shown in the drawings or position relationship, it is for only for ease of the description present invention and simplifies description, rather than instruction or hint indication device or element must have specific orientation, with specific azimuth configuration and operation, be therefore not considered as limiting the invention。Additionally, term " first ", " second " are only for descriptive purposes, and it is not intended that indicate or hint relative importance。
Without loss of generality, the present embodiment illustrates with the installation of girder steel bracket, should be understood that and see, except the installation for girder steel bracket, the adjustable balanced type member mounting device of the application can also be applied to the installation at certain altitude of other weight bigger component, the especially installation of various components below immersed tube top board。
Referring to Fig. 1, the adjustable balanced type member mounting device of the present embodiment, including rack beams platform, the first end of described rack beams platform is connected above girder steel bracket installation unit。In order to realize the balance of whole device at girder steel bracket after fixing, the second end of rack beams platform is connected to simulation girder steel bracket 3, it is preferable that the simulation size of girder steel bracket 3, shape are basic identical with girder steel bracket with weight。Wherein the first end and the second end are the opposition two ends of a structure, if the first end refers to left end, then the second end refers to right-hand member；First end refers to front end, then the second end refers to rear end。Additionally, be distributed with multiple hanger 6 at the two ends of described rack beams platform, the described hanger 6 of part is connected with steel wire rope 8, for mounting with handling apparatus。Can be obtained by general knowledge, the lifting in later stage will be realized, and make adjustable balanced type member mounting device steady as far as possible, it is clear that steel wire rope 8 should not only connect with the hanger 6 of wherein one end。Additionally, due to girder steel bracket installation unit needs to enter into specific installation site in installation process, in order to avoid now installation environment interferes with steel wire rope 8, it is preferable that the steel wire rope 8 of the first end connects the hanger 6 inside girder steel bracket installation unit。Wherein, definition is outside near end, and away from end is inner side。In order to realize regulating the balance of whole device, it is preferable that connecting multiple balance sling on the diverse location of described rack beams platform, each balance sling can work alone thus realizing the balance adjustment of difference, is finally reached the balance adjustment of whole device。
The present embodiment provides the specific constructive form of a kind of rack beams platform bag, specifically, rack beams platform includes two parallel girders 1, and connect the crossbeam 2 of two described girders 1, its middle cross beam 2 primarily serves booster action, therefore crossbeam 2 quantity and along girder 1 layout need can carry out appropriate design in conjunction with concrete stressing conditions。Between preferred all described crossbeams 2 parallel to each other, and described crossbeam 2 and girder 1 in the same plane。Additionally, the hanger 6 in the present embodiment may be located on girder 1, it is also possible to be positioned on crossbeam 2。It should be appreciated that this form of the present embodiment is not the unique version of rack beams platform。
Additionally, the girder steel bracket installation unit of the present embodiment includes laying column 5 and fixing beam 4；Described column 5 of laying is erected in above the first end of described rack beams platform, and is connected with described rack beams platform；Described fixing beam 4 lies across in the described side laying column 5, and is connected with described rack beams platform。The quantity laying column 5 described in preferably is four, thus realizing the steady installation of girder steel bracket。Certainly, the quantity laying column 5 may also be two, three, five ..., as long as steadily installing of girder steel bracket can be realized。In the present embodiment, it is preferable that described fixing beam 4 is parallel with above-mentioned crossbeam 2, and fixing beam 4 is positioned at the top of girder 1, and connects two girders 1。Described fixing beam 4 being threaded hole, laying after on column 5 thus being fixed at girder steel bracket, by the machinery such as bolt or screw is first, girder steel bracket is fixed。
In the present embodiment, it is preferable that described suspender is chain block 7, and the quantity of chain block 7 is four, and is respectively between two above the first end and second end of rack beams platform。Each chain block 7 is connected with rack beams platform preferably by snap ring 9, thus realizing the balance adjustment of this hanger 6 position, is realized the adjustment of multiple spot by multiple bottle gouards moved by hands, is finally reached the purpose regulating device balance。It should be noted that this kind of suspender the not exclusive structure that can realize device balance adjustment。
The adjustable balanced type member mounting device using the present embodiment carries out, in the installation process of girder steel bracket, girder steel bracket being placed in girder steel bracket and laying on column 5, it is preferable that fixed by the fixing beam 4 of connecting bolt and girder steel bracket。By chain block 7 adjustment after fixing, by tower crane or crane, girder steel bracket delivered to appointment position after adjustment, carry out hole adjustment, bolt are executed the operations such as stubborn, by tower crane or crane, adjustable balanced type member mounting device is fallen to refer to allocation after installation and carry out next girder steel bracket installation。
The adjustable balanced type member mounting device of the present embodiment has simple in construction, light advantage, and can realize the quick location of girder steel bracket in installation process。By using contrast to find, originally the installation of girder steel bracket needs 2.0h/ block, only needs 0.5h/ block after improvement, therefore can improve the installation effectiveness of 3 times；Additionally, every piece of girder steel bracket needed 4 people to install originally, after improvement, only need 3 people, it is necessary to workmen decrease 25%, and the input of mechanical one-shift also greatly reduces；The more important thing is, reduce security risk, it is not necessary to too many safety devices are installed。
Embodiment of above is merely to illustrate the present invention, but not limitation of the present invention。Although the present invention being described in detail with reference to embodiment, it will be understood by those within the art that, technical scheme is carried out various combination, amendment or equivalent replacement, without departure from the spirit and scope of technical solution of the present invention, all should be encompassed in the middle of scope of the presently claimed invention。
