Referring to fig. 1 and 4, the supporting branched chain 47 includes a supporting frame 471, a supporting plate 472, a locking rod 473, a stopper 474 and a return spring rod 475, wherein the supporting frame 471 is symmetrically installed on the upper end surface of the clamping plate 43 in a front-back manner, a supporting connecting groove matched with the supporting frame 471 is formed on the lower end surface of the supporting plate 472, the supporting plate 472 is sleeved on the supporting frame 471 through the supporting connecting groove, the supporting frame 471 is provided with a supporting groove, a plurality of sets of placing through grooves matched with the supporting groove are uniformly formed on the supporting plate 472 and on the side edge of the supporting connecting groove from top to bottom, the locking rod 473 passes through the placing through groove and is clamped inside the supporting groove, a plurality of sets of limiting grooves are formed on the opposite surface of the supporting plate 472, the stopper 474 is installed inside the limiting groove through a hinge, the return spring rod 475 is installed between the limiting groove and the stopper 474, and when the steel door works specifically, according to the height of the fire door 5, establish backup pad 472 cover and establish suitable height on supporting even frame 471, pass lock bar 473 again and place logical groove joint and support inslot portion, backup pad 472's use can prevent fire door 5 to the steel and support limiting displacement, it takes place to rock to avoid fire door 5 to be too high in the installation of counterpointing to prevent the steel, influence the fire door 5 counterpoint installation effect of steel, the dog 474 that contacts with the fire door 5 of steel gets into spacing recess through return spring lever 475 inside, wherein prevent fire door 5 with the steel and contact and be located the dog 474 of rearmost side and can prevent fire door 5 to the steel and play limiting displacement, it slides forward to avoid fire door 5 to prevent fire door 5 in the counterpoint installation, influence the fire door 5 installation effects of steel.

The invention provides a steel fireproof door assembling and positioning tool in a steel fireproof door assembling and positioning process, which comprises the following steps of: the first step is as follows: placing treatment: put fire door 5 between grip block 43 through the manual work with the steel, rotate lead screw 42 and drive regulating block 45 and remove in opposite directions, regulating block 45 removes in opposite directions the in-process mutually supports through inclined plane and even piece 44 and drives grip block 43 and remove in opposite directions, and then prevents fire door 5 to the steel and carry out the centre gripping spacingly.

The second step is that: movement adjustment: promote to remove frame 1 and move to door frame department through gyro wheel 2, rethread external force locks gyro wheel 2 and handles, and winding motor 31 starts to drive and winds the roller 32 and rotate, and then drives haulage rope 34 and drives and adjust frame 36 and rotate round axis of rotation 35 through sliding block 37, adjusts frame 36 and rotates the in-process and drive fire door 5 and the door frame through fixture 4 and align, and fire door 5 impels to door frame department through fine setting branch chain 30 with the steel at last.

The third step: mounting treatment: the limiting plate 11 is installed inside the connecting groove through the limiting bolt 12, and the steel fireproof door 5 is installed on the door frame through a hinge manually.

The fourth step: collecting by using the device: after the steel fireproof door 5 is installed, the screw rod 42 is rotated to drive the adjusting block 45 to reset, the clamping plate 43 resets through the reset spring rod 38, the movable rack 1 is pushed to move out from the installation position through the roller 2, and the work is finished.

The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention, and various modifications and changes may be made by those skilled in the art. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
