The utility model is realized by adopting the following technical scheme:
the utility model provides a flange is to mouthful device, including shaft-like handle, the perpendicular roof pressure pole of constituteing by montant and horizontal pole, insert the L type bracing piece that the stub bar in the last anchor stud hole of flange constitutes by stock and during the use, the vertical fixation has the atress pole on the stock, the atress pole is located same one side of stock with the stub bar, handle one end vertical fixation is in the montant of perpendicular roof pressure pole, the handle is parallel with the horizontal pole of perpendicular roof pressure pole and the horizontal pole of handle and perpendicular roof pressure pole is located the both sides of the montant of perpendicular roof pressure pole respectively, during the use, the tip roof pressure of the horizontal pole of perpendicular roof pressure pole is in the periphery of lower flange, the montant of perpendicular roof pressure pole is located between atress pole and the stub bar.
When the L-shaped support rod is used, the short rod of the L-shaped support rod is inserted into the upper fastening bolt hole of the upper flange, the end part of the cross rod of the vertical jacking rod is jacked against the circumferential surface of the lower flange, when a worker presses down the end part of one end of the handle, which is far away from the vertical jacking rod, the rod wall of the stress rod is contacted with the rod wall of the vertical rod of the vertical jacking rod, the lower flange moves towards one side direction due to jacking of the end part of the cross rod of the vertical jacking rod, the stress rod integrally moves towards the other side due to jacking of the vertical rod of the vertical jacking rod, so that the upper flange is integrally driven to move towards the other side, the upper flange and the lower flange are aligned, then bolts for connecting the upper flange and the lower flange are installed into the bolt hole, the handle is loosened to install the rest bolts, and finally, the fastening operation is carried out.
The beneficial effects produced by the utility model are as follows: the flange aligning device provided by the utility model is used for aligning, and only one person can finish the flange aligning when the flanges are aligned, so that the labor cost is reduced, the working efficiency is improved, the construction safety is improved, and good economic benefits and safety benefits are achieved.

Detailed Description
The utility model provides a flange is to mouthful device, including shaft-like handle 5, the perpendicular roof pressure pole of constituteing by montant 8 and horizontal pole 9, the L type bracing piece of constituteing by stock 6 and the quarter butt 7 that inserts in last fastening bolt hole 3 of upper flange 1 during the use, vertically fixed has stress pole 10 on stock 6, stress pole 10 and quarter butt 7 are located same one side of stock 6, 5 one end vertical fixation in montant 8 of perpendicular roof pressure pole of handle, handle 5 is parallel with the horizontal pole 9 of perpendicular roof pressure pole and handle 5 is located the both sides of the montant 8 of perpendicular roof pressure pole respectively with the horizontal pole 9 of perpendicular roof pressure pole, during the use, the tip roof pressure of the horizontal pole 9 of perpendicular roof pressure pole is in the periphery of lower flange 2, the montant 8 of perpendicular roof pressure pole is located between stress pole 10 and the quarter butt 7.
When the L-shaped support rod is used, the short rod 7 of the L-shaped support rod is inserted into the upper fastening bolt hole 3 of the upper flange 1, the end part of the cross rod 9 of the vertical jacking rod is jacked against the circumferential surface of the lower flange 2, when a worker presses the end part of the handle 5, which is far away from the end part of the vertical jacking rod, the rod wall of the stress rod 10 is in contact with the rod wall of the vertical rod 8 of the vertical jacking rod, the lower flange 2 moves towards one side direction due to jacking of the end part of the cross rod 9 of the vertical jacking rod, the stress rod 10 integrally moves towards the other side due to jacking of the vertical rod 8 of the vertical jacking rod, the upper flange 1 is driven to integrally move towards the other side, the upper flange 1 and the lower flange 2 are aligned, then bolts for connecting the upper flange and the lower flange 2 are installed into the bolt holes 12, the handle 5 is loosened to install the rest bolts, and finally, the fastening operation is carried out.
