A kind of hanger structure of bridge girder erection machine of the present embodiment, as depicted in figs. 1 and 2, its main body are a kind of annular fixed disks 1,
And screw rod fixture 2 is additionally provided with annular fixed disk 1.Described annular fixed disk 1 is the stainless steel tubular structure of ring-type, its
It is inside and outside to be coated with corrosion-inhibiting coating.And a square base 3 is provided with the center of annular fixed disk 1, two of base 3 are right
While it is fixed on the inner ring wall of annular fixed disk 1.The base 3 is typically to exist with certain thickness stainless steel plate, its thickness
Between 10cm-15cm, and the upper surface of base 3 is provided with a circular trough, and the first screw rod 201 is combined with by circular trough.Described
The bottom of one screw rod 201 be provided with it is T-shaped expand end, by by it is T-shaped expand end and match somebody with somebody with circular trough merge and be equipped with axle in its upper and lower both sides
Linking is held, so that the first screw rod 201 can be stably fixed on base 3 and can be around the axis rotation of the first screw rod 201.
Sleeve 202 is socketed with the first screw rod 201, the described inside of sleeve 202 is provided with internal thread, the first screw rod 201
During rotation, sleeve 202 can move axially along the first screw rod 201.And the both sides of sleeve 202 are symmetrically arranged with ears fixed seat
2051, each ears fixed seat 2051 is hinged with a first connecting rod 203, and the first connecting rod 203 of both sides is in same level
On.Described first connecting rod 203, which passes annular fixed disk 1 and passes direction one end at it, is hinged with second connecting rod 204.Described
Second connecting rod 204 is the bar linkage structure for being hinged on the bottom of annular fixed disk 1, and second connecting rod 204 can rotate around pin joint, both sides
Second connecting rod 204 at grade and spacing of two second connecting rods 204 in maximum folding between it is more than box beam
The widest part, to ensure that the present apparatus can be placed and is clipped in box beam.And it is provided with inside elastic clip in the end of second connecting rod 204
Disk 205, by elastic chuck 205, just face is contacted to reach the effect of resilient clamp with box beam both sides.
The principle of the present embodiment：The device in multiple the present embodiment is placed in box beam before use, showing first, and will
Two second connecting rods 204 of each device are clipped in the both sides of box beam.Then slowly rotating the first screw rod 201 makes sleeve 202 downward
It is mobile.When sleeve 202 moves down, the first connecting rod 203 of both sides can be driven to push out.And the first connecting rod 203 and
The pin joint of two connecting rods 204 is higher than second connecting rod 204 and the pin joint of annular fixed disk 1, therefore first connecting rod 203 promotes second to connect
When bar 204 rotates, second connecting rod 204 rotates around the pin joint of itself and annular fixed disk 1, and two second connecting rods 204 are provided with elasticity
The inside move toward one another in one end of chuck 205, so as to reach the effect of clamping.The elastic chuck 205 of both sides contacts simultaneously with box beam
