Hoisting device with circular rail moving and steering

Abstract

The invention discloses a hoisting device with circular rail moving and steering. The device comprises an annular rail, bearing vehicles, a bearing platform and a lifting and hoisting support. The lifting and hoisting support is arranged on the bearing platform, the two sets of bearing vehicles are arranged below the bearing platform, the two sets of bearing vehicles are arranged on two sides of the bearing platform respectively, the two sets of bearing vehicles are arranged on the annular rail, and the two sets of bearing vehicles run in circles on the annular rail. According to the annular rail, the hoisting annular rail is built in a modular mode, the structure is simple, an assembling speed is fast, and disassembling is easy. The hoisting device of the invention adopts a three-stage balance beam design, and a lowermost-stage balance beam is connected with the bearing platform. According to the design, load-bearing loads can be evenly distributed to the bearing platform, the bearingplatform can play a role to the maximum extent, and a purpose of uniform loading is achieved. In the design, the three-stage balance beam is only arranged, the structure is simple, stability is reliable and the device is suitable for being used on a circular rail.

Description

technical field [0001] The invention belongs to the technical field of large-scale hoisting equipment, and more specifically relates to a hoisting device with a ring rail moving and steering. Background technique [0002] The ring rail crane is a large A-arm type hoisting equipment that moves on a fixed ring track. It has many advantages such as simple structure, low grounding specific pressure, and huge lifting capacity. It has an irreplaceable important position in the hoisting field. [0003] Modular design and construction in the engineering field has become a new trend. Whether it is in the field of marine engineering, in the petrochemical field, or in other fields such as bridge construction, it has gradually tended to the modular design and installation mode. [0004] In terms of petrochemical hoisting, large-scale module installation is used to speed up construction and maximize investment benefits. This requires that the lifting equipment must be super-sized. Alth...

Problems solved by technology

However, its maximum lifting moment is only 88000t.m, and due to the limitation of the crawler crane structure (mainly the limitation of the slewing device), the crawler crane can no longer develop forward in terms of lifting moment.
