Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all embodiments, and all other embodiments obtained by a person of ordinary skill in the art without creative efforts based on the embodiments of the present invention belong to the protection scope of the present invention.

In an embodiment, referring to fig. 1-3, the utility model provides a technical solution, a lower base fixture for a bridge girder erection machine, which includes a base 1, a reinforcing rod 2 is arranged inside the base 1, and adjustable connection units 3 are detachably mounted at four corners of the top end of the base 1.

In this example, the base 1 is used as a support platform for the adjustable connection unit 3, and the reinforcing rods 2 are used to enhance the stability of the base 1.

Preferably, the base 1 is square, and the reinforcing rod 2 is cross-shaped.

In this example, base 1 is the square type in order to reach the supporting effect, save material simultaneously, and stiffener 2 is the cross messenger stiffener and forms the mutual bracing power for base 1 stability is better.

Preferably, the adjustable connection unit 3 comprises a first connection plate 31, the top end of the first connection plate 31 is detachably connected with an upper connection piece 32, and a lower connection disc 33 is arranged on one side of the upper connection piece 32.

In this example, the adjustable connection unit 3 is used for placing iron rods and adjusting the welding positions of the iron rods, and the lower connection disc is used for placing vertical iron rods and can also be used for placing some chain joints.

Specifically, the iron rods are placed on the upper connecting piece 32 through bolts, and the other iron rod is placed on the lower connecting disc through screws to weld the two iron rods.

Preferably, the upper connecting member 32 includes a first connecting post 321, two ends of the first connecting post 321 are fixedly connected to a first connecting circular plate 322, a plurality of first connecting holes 323 are disposed on the first connecting circular plate 322, and the first connecting circular plate 322 is detachably connected to the bottom end of the first connecting base 324.

In this example, the upper connecting member 32 is used for placing an iron rod, and the position of the circular hole on the first connecting seat 324 corresponding to the first connecting hole 323 is adjusted, so as to adjust the welding position of the iron rod.
