Bridge pushing equipment angle adjuster

Abstract

The invention relates to the field of bridge pushing equipment accessories, in particular to a bridge pushing equipment angle adjuster which can be used for adjusting the angle between pushing equipment and a bridge line shape in bridge engineering pushing construction. The bridge pushing equipment angle adjuster comprises a base which can be connected with the top of a jack of pushing equipment, a cylinder body arranged on the upper surface of the base, and a sunken groove formed in the top of the cylinder body, the sunken groove comprises a semispherical groove with a downward spherical surface and a cylindrical groove communicated with the semispherical groove, and a semispherical body matched with the semispherical groove is arranged in the sunken groove. The semispherical body can universally rotate in the sunken groove, a supporting rod extending out of the cylinder body is arranged at the plane end of the semispherical body , a distance exists between the rod wall of the supporting rod and the cylindrical groove, and a supporting top plate is arranged at the end, extending out of the cylinder body, of the supporting rod. The bridge pushing equipment angle adjuster can be used for adjusting the included angle between a pushing device and the beam body in bridge pushing construction, and can adjust the relative rotation angle between the beam body and the supporting device in the horizontal deviation correction process.

Description

technical field [0001] The invention relates to the field of bridge jacking equipment accessories, in particular to an angle adjuster for bridge jacking equipment, which can be used in bridge engineering jacking construction to adjust the angle between the jacking equipment and the alignment of a bridge. Background technique [0002] In the construction of long-span bridges, more and more bridges use the jacking method to cross obstacles from the air. During the construction, the jacking equipment is installed on the temporary support. The upper part of the jacking equipment jack supports the beam body through the pad beam. There are horizontal and vertical slopes, which will form a certain angle with the pushing equipment. Generally, thin steel plates of different thicknesses are used for adjustment.

Problems solved by technology

[0002] In the construction of long-span bridges, more and more bridges use the jacking method to cross obstacles from the air. During the construction, the jacking equipment is installed on the temporary support. The upper part of the jacking equipment jack supports the beam body through the pad beam. There are horizontal and vertical slopes, which will form a certain angle with the pushing equipment. Generally, thin steel plates of different thicknesses are used for adjustment. The adjustment method is cumbersome, and it is difficult to guarantee the force and alignment of the bridge; The bridge and supporting equipment will rotate relative to a certain angle. During the rotation, the beam body will be damaged, and the support may be unstable. It is difficult to guarantee the appearance of the beam body and construction safety.

[0003] At present, there is no effective and simple device that can easily adjust the angle between the pushing device and the bridge alignment and the angle of the lateral correction process.
