Below in conjunction with Fig. 1-Fig. 3 the utility model is described in detail.

Example

An auxiliary device for arch frame processing, comprising a bottom plate 3 located between two support beams 5, a support 4 is connected to the bottom plate 3, a top plate 2 is connected to the top of the support 4, and a top plate 2 is connected to the bottom plate 3 There is a hydraulic telescopic rod 8, and the top plate 2 is provided with a through hole 9 for the hydraulic telescopic rod 8 to protrude.

As shown in FIG. 1 , the arch 1 is divided into a longer first segment 101 and a shorter second segment 102 , and the second segment 102 needs to be welded at both ends of the first segment 101 . The hydraulic telescopic rod 8 includes a cylinder and a piston rod. The piston rod extends out of the cylinder and withstands the arch 1. The piston rod lifts the arch 1. The arch 1 slowly deflects as the piston rod elongates. After the deflection is completed As shown in FIG. 3 , the arch 1 can be continuously lifted to make the arch 1 reach a suitable height, which is convenient for workers to perform welding.

In order to ensure the smooth deflection of the arch 1 on the piston rod, the top of the piston rod is arranged in a hemispherical shape, which reduces the resistance of the piston rod to the deflection movement of the arch 1 .

After the top of the cylinder barrel is connected with the lower surface of the top plate 2, the cylinder barrel can support the top plate 2, and the auxiliary support member 4 supports it to ensure that the whole auxiliary device can bear a large weight.

The upper surface of the top plate 2 is flush with the upper surface of the support beam 5, so that the arch 1 is placed horizontally, so that the second segment 102 is aligned with the end face of the first segment 101 during welding.

A wheel 10 is connected to the bottom of the bottom plate 3, and the wheel 10 is equipped with a braking device. By setting the wheels 10, it is convenient to move the whole auxiliary device.

After the arch 1 is jacked up and separated from the crossbeam 5, in order to prevent the arch 1 from pressing the entire auxiliary device to one side and toppling over, a limit push rod 11 that is in contact with the lower surface of the crossbeam 5 is connected on the bottom plate 3, Limit the tipping of the auxiliary device to one side.

The space-limiting push rod 11 is connected with a telescopic device, and the telescopic device includes a sleeve 6 fixedly connected to the base plate 3 and a square rod 7 that is movably arranged in the sleeve 6, and the square rod 7 and the position-limiting push rod 11 connections.
