Embodiment Construction

[0015] Below in conjunction with accompanying drawing example the present invention is described in further detail:

[0016] Such as figure 1 and figure 2 The shown marine crane includes two guide rail beams 1 equipped with longitudinal rails 1-1, racks 13 are installed at the bottom of the two guide rail beams 1; The running beam 4 that travels on the two longitudinal guide rails 1-1, the running beam 4 includes two parallel beams 4-1 and longitudinal beams 4-2 lapped on the two ends of the two beams 4-1. The root longitudinal beam 4-2 is respectively welded and connected with two beams 4-1; a connecting plate is welded between the beams 4-1; two wheel axles 6-2 are respectively installed on each longitudinal beam 4-2 through bearings. 1. Each wheel shaft 6-1 is equipped with a walking wheel 6 that is crimped with the longitudinal rail 1-1, and a guide wheel is installed between each longitudinal beam 4-2 and the guide rail beam 1 through the guide wheel shaft 14-1 14. Th...

Abstract

The invention discloses a marine travelling crane relating to the technical field of manufacturing of the marine travelling cranes. The marine travelling crane comprises two guide rail beams provided with longitudinal guide rails, a travelling crane transverse beam which moves on the two longitudinal guide rails through walking wheels, and hoisting winch systems arranged on the travelling crane transverse beam, wherein racks are arranged at the bottoms of the guide rail beams; each of the two ends of the travelling crane transverse beam is at least provided with one walking small gear driven by a motor; the walking small gears are engaged with the racks; a synchronizer is arranged between the racks at the two ends of the travelling crane transverse beam; and the travelling crane transverse beam is provided with the two hoisting winch systems. Compared with the prior art, the marine travelling crane has the advantages that the problems that the hoisting accuracy and the hoisting reliability of an existing marine common travelling crane are poor can be solved.

Description

technical field [0001] The invention relates to the technical field of marine crane manufacturing, in particular to a special crane used for hoisting objects on a ship. Background technique [0002] Most of the cranes currently used on ships are ordinary cranes, which generally include two rail beams with longitudinal tracks and a traffic beam that travels on the two longitudinal rails through traveling wheels. wheel longitudinal traveling device and hoisting winch system. This kind of crane usually has only one lifting winch system, which has a large range of activities and a high lifting height. It is only suitable for use in workshops on land or outdoor large-scale lifting places. There are the following problems in the use on engineering ships: 1. The engineering ship is driving When the splint will shake, because the driving beam walks on the guide rails through the traveling wheels, the stability of the driving is poor; When using it, sometimes shaking and steel pipe...
