Description

Technical Field

[0001] This application relates to the technical field of 321 steel frame bridge cross pin extractors, and in particular to a bridge cross pin extractor. Background Technique

[0002] A bridge cross pin extractor is a special tool used in the maintenance or demolition of the truss link pin structure of a 321 steel frame bridge. Cross pins are usually used to connect various components in the bridge structure to ensure the stability and safety of the structure. However, during bridge maintenance or demolition, it may be necessary to remove these cross pins for further operations. The types of bridge cross pin extractors may vary depending on the manufacturer, design purpose, and applicable scenarios.

[0003] Currently, when replacing bridge components of a 321 steel frame bridge, strengthening the bridge structure, or demolishing old bridges, the existing cross pins are mostly fixed tightly, increasing the difficulty of extraction for workers, increasing the labor intensity of workers, and at the same time having poor extraction efficiency. At the same time, in the prior art, when adjusting the truss link pins of a 321 steel frame bridge, a hammer is mostly used to hit, which is extremely prone to dangerous situations. Therefore, a bridge cross pin extractor is proposed for the above problems. Summary of the Invention

[0005] According to one aspect of the present application, a bridge cross pin extractor is provided, including a sleeve, a nut, a rotating column, a semi-circular part, a screw rod, a connecting component, and an electric wrench. The left end of the sleeve is slidably connected with a rotating column, the left end of the rotating column is fixedly connected with a semi-circular part, the right end of the rotating column is fixedly connected with a screw rod, the surface of the right end of the screw rod is threadedly sleeved with a nut, the nut is installed in the inner cavity of the right end of the sleeve, and the right end of the screw rod is detachably connected with the electric wrench through the connecting component.

[0006] Furthermore, the side view cross-section of the semi-circular part is in a semi-circular ring structure, and the semi-circular part is coaxially arranged with the rotating column and the screw rod.

The connection head is installed on the right end surface of the lead screw. A connection ring is sleeved on the right end surface of the connection head. The connection ring is in contact with the connection plate. A connection seat is fixedly sleeved inside the connection plate. The right side of the connection seat is connected to the rotating end of the electric wrench.

[0009] Further, the connection groove is formed in the right side surface of the connection head. The cross section of the connection groove is in a shape of a single character. A connection block is snap-fitted in the connection groove.

[0010] Further, the number of the connection columns is two. The two connection columns are symmetrically distributed with respect to the connection block. The connection columns penetrate through the side surface of the connection ring. The end of the connection column is threadedly sleeved with a connection nut.
