Abstract

The invention discloses a pile-around revolving crane and belongs to the field of cranes. The pile-around revolving crane comprises a lifting mechanism, a revolving platform and a base. The revolving platform is arranged at the upper end of the base, the lifting mechanism is arranged on the revolving platform, the base comprises a fixed base, a cylindrical supporting column and a revolving supporting ring, one end of the cylindrical supporting column is connected to the fixed base, and the other end of the cylindrical supporting column is connected to the revolving supporting ring. The revolving platform comprises a rotary table, a forward roller assembly and a backward roller assembly. The forward roller assembly is arranged on the rotary table, and the backward roller assembly is arranged on the rotary table through a backward roller supporting base. The forward roller assembly and the backward roller assembly each comprise a roller support and a roller, wherein the roller support is rotationally connected to the rotary table or the backward roller supporting base, and the roller rolls on the upper and lower surfaces of the revolving supporting ring along with rotation of the revolving platform. Due to the fact that the revolving plane of each roller support is parallel to the revolving axis of the revolving platform, when the surface of the revolving supporting ring is not flat, the roller supports will revolve to enable the rollers to press the revolving supporting ring.

Description

technical field [0001] The invention relates to the field of cranes, in particular to a pile-wrapping slewing crane. Background technique [0002] At present, the slewing crane around the pile is usually installed on the legs of various offshore platforms. It is widely used because of its small platform space, compact structure, large lifting capacity, and long lifting radius. [0003] The pile-wound slewing crane mainly includes a base, a slewing platform and a lifting mechanism. The slewing platform is rotatably set on the base, and the lifting mechanism is set on the slewing platform. There is enough space in the middle of the base and the middle of the slewing platform. To allow the pile legs to pass through, in small pile-encircling slewing cranes, the slewing platform and base are usually connected by slewing bearings; in large-scale pile-encircling slewing cranes, the slewing platform and base Roller connection, specifically, a slewing support ring is set on the base...
