Abstract

The invention discloses a rail for hoisting machinery. The rail comprises an upper track arranged on the edge of the upper surface of a girder of the hoisting machine, a lower rail is arranged at thelower edge of the side surface of the main beam of the lifting machine, the inclination angle is respectively formed in the rails, the upward or inclined upward moment is provided for the upper trolley connected with the main beam through the inclination angle so as to prevent the upper trolley from overturning, so that the upper trolley can be independently arranged on the outer side of the girder of the hoisting machine, so that guiding and supporting can be provided for the walking of the upper trolley, and the anti-dropping device for preventing the trolley from overturning can be prevented. By applying the machine provided, due to the fact that the upper trolley can be independently kept stable, no physical connection exists between the upper trolleys, in addition, the overall heightof the machine can be reduced, the height of the roof of a workshop of the workshop can be reduced, and the manufacturing cost of the workshop can be reduced.

Description

technical field [0001] The invention relates to the field of shipbuilding equipment, in particular to a track for hoisting machinery. Background technique [0002] With the new development of luxury cruise ships, some shipyards have begun to build indoor docks for luxury cruise ships in order to pursue the construction environment and engineering progress. Double-girder shipbuilding gantry cranes are required in indoor docks. The lifting height of the shipbuilding gantry crane needs to meet the requirements for the height of the cruise ship. At the same time, because increasing the height of the indoor dock workshop will increase its construction cost, it is necessary to limit the total height of the crane. [0003] Since the integral type upper trolley needs to pass through the lower trolley under the requirement of the turning process, the total height of the integral upper trolley is above the lower trolley. However, due to the restrictions on the overall height of the...
