Description
Technical field
The present invention relates to a kind of beam-hanging traveling crane on high speed railway Bridge Erector, particularly the smooth formula beam-hanging traveling crane of one.
Background technology
Adopting tire type beam conveying vehicle entirety to pack high speed railway Bridge Erector by one of obstacle of running into during tunnel is beam-hanging traveling crane excessive height on Bridge Erector, collides, therefore overhead traveling crane dismounting can must be crossed tunnel with top, tunnel.Obviously, this quite bothers, and time-consumingly bothersomely to take a lot of work.
Summary of the invention
Cai only have after dismounting overhead traveling crane by tunnel, the time-consuming deficiency such as to take a lot of work to overcome existing Bridge Erector, the invention provides a kind of smooth formula beam-hanging traveling crane, this invention makes the height of Bridge Erector beam-hanging traveling crane greatly reduce, thus makes tire type beam conveying vehicle entirety pack high speed railway bridge formation function to pass through tunnel smoothly.
The technical solution adopted for the present invention to solve the technical problems is: the vehicle frame of described beam-hanging traveling crane is divided into main car frame and subframe two parts.Main car frame by two vertical binding beams couple together add counterweight crossbeam and standard horizontal beams is formed, fixed pulley group integrated and overhead traveling crane traveling gear is installed in main car frame, for reducing height further, have employed four groups of shift units and walking engine installation by being arranged on the traveling gear adding counterweight crossbeam and standard horizontal beams two ends, main car frame is the main load larrying member of beam-hanging traveling crane.Four spoon shape cantilever beams are installed in the outside of standard horizontal beams, spoon shape cantilever beam and some horizontal-associate beams connect and compose cantilevered subframe, cantilevered subframe is equipped with two electric winchs, and subframe to hang outside main car frame in main car frame standard horizontal beams side and with spoon shape cantilever beam form and lower than main car frame.Like this, just by winch in prior art, the tall and big beam-hanging traveling crane be vertically superposed on fixed pulley group is spread out and becomes short smooth formula beam-hanging traveling crane.Four groups of shift units of described traveling gear adopt chain sprocket drive, can make like this to be staggeredly arranged before and after walking engine installation and shift unit, thus reduce the overall height of traveling gear.In addition, in order to beam-hanging traveling crane longitudinal plane length can be shortened, steel rope can be avoided again to enter to restrict the increase of drift angle, present invention employs steel rope and add leading sheave on counterweight crossbeam directly around on running block by being arranged on main car frame.For the needs that accommodation curve is set a roof beam in place, described beam-hanging traveling crane is also provided with sideslip oil cylinder, can make fixed pulley group overall lateral shuttle slippage nominal distance by the push-and-pull of sideslip oil cylinder.Meanwhile, in order to the overall width of constriction beam-hanging traveling crane, in order to avoid collide with the roof of a tunnel of arch, the traveling gear of overhead traveling crane is arranged on (inclined beam-and-rail) on the track on crane ' s major girder interior plate by the present invention.
The invention has the beneficial effects as follows: the smooth formula beam-hanging traveling crane of the Very Low Clearance that this invention provides, for the high speed railway Bridge Erector manufacturing and designing overall height lower creates advantage, also packing high speed railway Bridge Erector for tire type beam conveying vehicle entirety has cleared away a large obstacle by tunnel smoothly simultaneously, thus greatly can improve the erection progress of line of high-speed railway bridge, its Social and economic benef@is huge.
