Problems solved by technology

[0005] The purpose of the present invention is to overcome the defects and deficiencies of the existing general column type King Post Crane and mast type Mast Crane crane with complex force structure, high fixed column height and low lifting equivalent, and provide a simple load-bearing structure with large lifting equivalent. The structure of the fixed-column full-slewing crane, and the height of the fixed column can be adjusted appropriately to meet the needs of applications with height restrictions

Embodiment Construction

[0030] The present invention will be described in further detail below in conjunction with accompanying drawing description and specific embodiment:

[0031] see Figure 1 to Figure 4 , a fixed column type full-slewing crane, including a fixed column, a slewing bearing, a slewing mechanism, a winch, a boom, a steel rope 10 and a hook 12, and a flange 2 is arranged on the outer surface of the middle and lower section of the fixed column. The flange 2 divides the fixed column into two parts, the upper fixed column 7 and the lower fixed column 1. A fixed column top shaft 17 is arranged on the center of the end surface of the top of the upper fixed column 7. A slewing bearing 3 is connected above the flange 2. The slewing bearing 3 The upper part is fixedly connected with the turntable 6, and the turntable 6 is provided with a hole larger than the outer diameter of the upper fixed column 7, so that the turntable 6 can rotate around the fixed column, and the turntable 6 is respecti...

Abstract

The invention relates to a fixed post type fully rotary crane, which belongs to crane transportation machinery for a boat. A flange (2) is arranged on the outer surface of the middle lower section of a fixed post, a fixed post top shaft (17) is arranged in the end surface center of the top of an upper fixed post (7), a rotary supporter (3) is connected above the flange (2), the upper part of the rotary supporter (3) is fixedly connected with a rotary table (6), a hanging arm (13) and a top pulley frame (8) are respectively hinged on the rotary table (6), a top bearing (11) and a top pulley group (9) are respectively and fixedly arranged on the top pulley frame (8), the top bearing (11) is sheathed onto the fixed post top shaft (17), a rotary mechanism (4) is arranged on the rotary table (6) or a lower fixed post (1), the integral height of the crane is reduced, in addition, the full rotation is realized, the operation of the whole machine is stable, the load bearing and the bending resistance capability of the crane are greatly improved, the service life is greatly prolonged, and the fixed post type fully rotary crane is particularly suitable for being used on large-scale floatingcrane boats and ocean engineering boats with crane weight limitation and navigation height limitation.

Description

technical field [0001] The invention relates to a fixed-column crane, in particular to a fixed-column full-slewing crane. It belongs to marine lifting and transportation machinery. Background technique [0002] The existing fixed-column cranes generally include two types, that is, the column-type King Post Crane and the mast-type Mast Crane. The turntable and the top pulley device of the King Post Crane-type slewing crane are integrated into one body through solidification of the steel structure, and the boom is installed on the On the turntable, a rotary part is formed. The top pulley device can be at the center of revolution of the fixed column, or it can deviate from the center of revolution. The entire rotary part is sleeved on the fixed column from top to bottom, and the lower part of the turntable has no support. The top of the fixed column is supported by a bearing assembly, and the lower part of the fixed column has an annular track parallel to the center of rotat...
