For achieving the above object, the technical scheme that bridge-type provided by the utility model is crossed the rail hoisting crane is: a kind of bridge-type is crossed the rail hoisting crane, comprise girder, the girder two ends cart that is connected respectively, girder is provided with for mobile Assembling bogie, and be used for crossing the girder track that rail docks with corresponding auxiliary girder track, have on the described girder and extend upward, and for the support beam section that two carts are distributed along the vertical direction, two carts are respectively cart and lower cart, described girder track cross rail butt end for being used for corresponding auxiliary girder track crosses that rail dock away from an end of lower cart, below the upper cart in the outside of crossing the rail butt end of girder track have for for girder track and corresponding auxiliary girder track with described on large Car Track corresponding to cart below cross the space of dodging that rail docks.
Described girder comprises the horizontal beam section, and the lower end of described support beam section is connected in an end of horizontal beam section, and described upper cart is connected on the support beam section away from an end of horizontal beam section, and lower cart is connected in the end away from the support beam section of horizontal beam section.
The lower end of described support beam section is installed with butt flange, is installed with the lower butt flange corresponding with upper butt flange in the horizontal beam section, and upper and lower butt flange is by the attachment bolt captive joint.
Described support beam section tilts to extend towards described upper cart.
Described bridge-type is crossed the rail hoisting crane and is also comprised for crossing the auxiliary girder track that rail docks with the girder track, have be used to the fixed part that is fixedly supported on the corresponding building on this auxiliary girder track, described girder track or auxiliary girder track cross the rail butt end be fixed with for girder track and auxiliary girder track removable be fixed together cross the rail blocking device.
The beneficial effects of the utility model are: bridge-type provided by the utility model is crossed on the girder of rail hoisting crane has upwardly extending support beam section, this support beam section can make two carts distribute at above-below direction, and so that upper and lower cart move and be assemblied in the large Car Tracks of the correspondence two with diff-H top, during use, the rail docking was located in girder track and the auxiliary girder track space of dodging below upper cart, upper cart can not impact the rail docking of crossing of major and minor beam orbit, guarantees both normal docking.And this two carts of crossing the rail hoisting crane can be supported on the large Car Track, and its load larrying member are good, and this rail hoisting crane of crossing is suitable for being applied in to the larger place of hoisting capacity requirement, and its manufacturing cost is little, and safety factor is high.
Description of drawings
Fig. 1 is the structural representation that bridge-type provided by the utility model is crossed a kind of embodiment of rail hoisting crane.
The specific embodiment
As shown in Figure 1, a kind of bridge-type is crossed the embodiment of rail hoisting crane, bridge-type among this embodiment is crossed the rail hoisting crane and is comprised girder 3, girder 3 two ends are fixed with respectively cart, girder is provided with the girder track 10 for mobile Assembling bogie 4, described bridge-type is crossed the rail hoisting crane and is also comprised for crossing the auxiliary girder track 7 that rail docks with girder track 10, mainly be with the existing difference of crossing the rail hoisting crane: the girder 3 that this bridge-type is crossed the rail hoisting crane comprises horizontal beam section 31 and the support beam section 32 that is connected in horizontal beam Duan Yiduan, this support beam section extends upward, and two carts are distributed at above-below direction, two carts are respectively for mobile and are assemblied in the upper cart 5 on the upper large Car Track 1 and are used for the mobile lower cart 9 that is assemblied on the lower large Car Track 11, herein upper, lower cart is suitable for mobile being assemblied in and has the upper of diff-H, on the lower large Car Track, wherein, upper cart 5 is connected on the support beam section 32 end away from the horizontal beam section, lower cart 9 is connected in the end away from the support beam section of horizontal beam section 3, the lower end of support beam section 32 herein is installed with butt flange, be installed with the lower butt flange corresponding with upper butt flange in horizontal beam section 31, on, lower butt flange is by the attachment bolt captive joint.Girder track 10 in the present embodiment cross rail butt end for being used for corresponding auxiliary girder track 7 crosses that rail dock away from an end of lower cart 9, below the upper cart 5 in the outside of crossing the rail butt end of girder track 10 have for for girder track 10 and corresponding auxiliary girder track 7 with described on upper large Car Track 1 corresponding to cart 5 below cross the space of dodging that rail docks.Have on the auxiliary girder track 7 in the present embodiment be used to the fixed part that is fixedly supported on the corresponding building 8, crossing between the rail butt end of described girder track 10 and auxiliary girder track 7 captiveed joint by being used for the rail blocking device 6 of crossing that is fixed together that girder track and auxiliary girder track is removable.
