Embodiment Construction
[0012] In order to further understand the content of the invention, features and effects of the present invention, the following examples are given, and detailed descriptions are as follows in conjunction with the accompanying drawings: figure 1 , figure 2 As shown, the track is a circular track 1 suspended from the top of the factory building 4, fixed connectors 2 are evenly distributed between the circular track and the top of the factory building, and a main beam 13 running along the track and its driving motors 3, 5 are movably installed on the track. , on the main beam, a dolly 14 running along the main beam and its driving motor are movably installed. On the top of the factory building outside the factory building door 12 on one side of the circular track, an outwardly extending outer beam on the same level as the main beam is installed. The outer beam can be a plurality of fixed beams 8 suspended on the top of the factory building. The fixed beam passes through the con...

The invention relates to a polar crane with an electric over-rail, which is characterized in that the rail is an annular rail hanged on the top part of a plant, a main beam and a driving motor thereof operating along the rail are movably arranged on the rail, a trolley and a driving motor thereof operating along the main beam are arranged on the main beam, the top part of the plant on the outer side of a plant gate on one side of the annular rail is provided with an outer beam which is arranged on the plane with the main beam and extend outwards, the top part of the plant is also provided with a middle rotating beam connecting the main beam and the outer beam, a rotating mechanism is arranged on the middle rotating beam, and an over-rail device is arranged on the middle rotating beam between the main beam and the outer beam. Therefore, the accurate hoisting can be realized at any point in the circular plant, and the stable and smooth transition can be achieved for the hoisting component from the circular plant to another plant. Moreover, the invention solves the problems of hoisting and hoisting-out of the circular plant. In addition, the invention has the advantages of simple structure, easy manufacture and high safety and reliability.
Description
technical field [0001] The invention relates to a rail crane, in particular to a ring crane with electric rail passing. Background technique [0002] The main girder of common crane at present all is that its two ends are installed on the rail and realizes the horizontal linear walking of cart along track, and trolley (electric hoist) lifts and lifts goods and walks longitudinally along main girder on main girder. However, in a circular factory building, such as nuclear power reactors and other dangerous environments with high radiation or high noise, it is required that the trolley and hoisted goods must be transported out of the factory building to another factory building or place, and the door of the factory building should be closed to prevent radiation, Noise or leakage of hazardous material. Therefore known rail crane just can't reach the requirements of hoisting, transporting out and closing the factory building door under the dangerous environment of circular facto...
