Movable tubular pile crane

Abstract

The invention relates to the technical field of cranes, in particular to a movable tubular pile crane. The crane comprises a main arm; a groove is formed in the main arm; a rotating shaft is fixedly installed in the groove; a damping plate is fixedly installed in the groove; a corner piece is rotationally installed on the rotating shaft; a disc and a suspension arm are fixedly installed on the corner piece; a side plate is fixedly installed on the main arm; a pushing and pressing piece is movably installed on the side plate; a balance spring is fixedly connected to the pushing and pressing piece; a center plate is fixedly installed on the side plate; and a lever is rotationally installed on the center plate. According to the crane, the corner piece is a connecting assembly of the suspension arm and the main arm, a sliding block is driven by a sliding block-crank structure to move up and down in a reciprocating mode, the pressure between the disc and the damping plate can be increased,the frictional resistance borne by the corner piece is increased, thus vertical shaking of a clamp suspension beam is reduced, the suspension arm can be directly locked, the clamp suspension beam is lifted in time when breaking down, and the safety of the crane is guaranteed.

Description

Technical field[0001]The invention relates to the technical field of cranes, in particular to a mobile pipe pile crane.Background technique[0002]In recent years, my country has accelerated the pace of machine replacement in the traditional production industry. The process layout of the concrete pipe pile production line generally requires a special crane for pipe pile production. The pipe pile crane adopts the form of a double beam and double trolley bridge crane, and the automatic clamp hanging beam is hung under the hook, which can replace the manual completion of pile removal, mold turning, mold opening and other processes.[0003]Usually, the running speed of the cart reachesIf the automatic clamp suspension beam suddenly stops when it is close to the pipe mold, the suspension beam will sway back and forth in the direction of the cart, making it difficult for the automatic clamp to locate quickly and accurately. Therefore, the general pipe pile crane will be equipped with an anti-...

Problems solved by technology

[0003] Usually, the running speed of the cart reaches If the lifting beam of the automatic clamp stops suddenly when it is close to the top of the pipe mold, the lifting beam will shake back and forth in the running direction of the cart, making it difficult for the automatic clamp to be positioned quickly and accurately. The swing arms are all simple articulated structures, which have no elastic adjustment and self-locking functions. They only have a lateral righting effect, but have no protective effect on the vertical shaking and loosening of the fixture hanging beam. In view of this, we propose a mobile pile crane
