Description
Technical field
The utility model relates to a kind of hanging beam overhead traveling crane that is used on the high speed railway bridge formation machine, particularly a kind of smooth formula hanging beam overhead traveling crane.
Background technology
One of obstacle that runs into when adopting rubber-tyred beam transportation vehicle integral body to pack high speed railway bridge formation machine by the tunnel is the hanging beam overhead traveling crane excessive height on the bridge formation machine, collides with the top, tunnel, so the overhead traveling crane dismounting can must be crossed the tunnel.Obviously, this quite bothers, time-consuming taking a lot of work.
Summary of the invention
Could be in order to overcome that existing bridge formation machine has only behind the dismounting overhead traveling crane by tunnel, time-consuming deficiency such as take a lot of work, the utility model provides a kind of smooth formula hanging beam overhead traveling crane, this invention greatly reduces the height of bridge formation machine hanging beam overhead traveling crane, passes through the tunnel smoothly thereby make rubber-tyred beam transportation vehicle integral body pack high speed railway bridge formation function.
The technical scheme that its technical matters that solves the utility model adopts is: the vehicle frame of described hanging beam overhead traveling crane is divided into main car frame and subframe two parts.Main car frame by two vertical binding beams couple together add the counterweight crossbeam and the standard crossbeam constitutes, integrated and the overhead traveling crane traveling gear of fixed pulley group is installed in the main car frame, for further reducing height, adopted four groups of shift units and walking engine installation with being installed in the traveling gear that adds counterweight crossbeam and standard crossbeam two ends, main car frame is hanging beam sky car owner's load larrying member.Four spoon shape cantilever beams are installed in the outside of standard crossbeam, spoon shape cantilever beam and some horizontal-associate beams connect and compose the cantilevered subframe, two electric winchs are housed on the cantilevered subframe, and subframe hangs outside the main car frame and is lower than main car frame in main car frame standard crossbeam one side and with spoon shape cantilever beam form.Like this, just winch in the prior art vertically being superposed on tall and big hanging beam overhead traveling crane on the fixed pulley group spreads out and becomes short smooth formula hanging beam overhead traveling crane.Four groups of shift units of described traveling gear are to adopt chain sprocket drive, and walking engine installation and shift unit front and back are staggeredly arranged, thereby reduce the overall height of traveling gear.In addition, in order to shorten hanging beam overhead traveling crane longitudinal plane length, the increase that can avoid steel rope to go into to restrict the drift angle again, the utility model has adopted steel rope to add leading sheave on the counterweight crossbeam directly around going into to running block by being installed in main car frame.Be the needs that accommodation curve is set a roof beam in place, described hanging beam overhead traveling crane also is provided with sideslip oil cylinder, and the push-and-pull by sideslip oil cylinder can make the whole lateral shuttle slippage of fixed pulley group nominal distance.Simultaneously, for the overall width of constriction hanging beam overhead traveling crane, in order to avoid collide with the roof of a tunnel of arch, the utility model is arranged on the traveling gear of overhead traveling crane on the track on the crane ' s major girder interior plate (beam-and-rail partially).
The beneficial effects of the utility model are: the smooth formula hanging beam of the Very Low Clearance that this invention provides overhead traveling crane, created advantage for manufacturing and designing the lower high speed railway bridge formation machine of overall height, also pack high speed railway bridge formation machine simultaneously and cleared away a big obstacle by the tunnel smoothly for rubber-tyred beam transportation vehicle integral body, thereby can improve the progress of setting up of high speed railway bridge along the line greatly, its society and economic benefit are huge.

The specific embodiment
Embodiment
Fig. 1～Fig. 4 is the disclosed embodiment of the utility model, described smooth formula hanging beam overhead traveling crane, comprise leading sheave 2, two groups of integrated 5, the two groups of running blocks 8 of fixed pulley group, lifting assembly 9 and two winchs 10, described hanging beam overhead traveling crane is installed on two girders 15 of bridge formation machine.Couple together and constitute the main car frame structure adding counterweight crossbeam 4 and two vertical binding beams 13 of standard crossbeam 6 usefulness.Two groups of fixed pulley groups integrated 5 are installed on the vertical binding beam 13, sideslip oil cylinder 3 is equipped with at the two ends of two groups of fixed pulley groups integrated 5 respectively, initiatively shift unit 1 and walking engine installation 7 are installed in the two ends that add counterweight crossbeam 4, passive shift unit 14 is installed at the two ends of standard crossbeam 6, four spoon shape cantilever beams 11 are installed in the outside of standard crossbeam 6, spoon shape cantilever beam 11 connects and composes cantilevered subframe (winch platform) with some horizontal-associate beams 12, and subframe end face absolute altitude is lower than main car frame.Two electric winchs 10 are installed on the cantilevered subframe, and the profile end face absolute altitude of electric winch 10 is lower than the profile end face absolute altitude of fixed pulley group integrated 5 slightly.Engine installation 7 drives active shift unit 1 and drives passive shift unit 14 by chain sprocket drive and moves on the pleurosternal track in two girders 15 of bridge formation machine.Be the balance that keeps deadweight always on the main car frame (contain fixed pulley group integrated etc.) and cantilevered subframe always to conduct oneself with dignity (containing winch), need to load iron sand in the counterweight crossbeam 4 and work as counterweight, with the trim moment that deadweight was produced of balanced cantilever formula subframe and electric winch 10 in adding of main car frame.The rope stretching process leading sheave 2 of electric winch 10 is directly into 8, two groups of running blocks 8 of rope precession assembly pulley and lifting assembly 9 parallel connections.Leading sheave 2 is installed in the outside that adds the counterweight crossbeam, hoisting rope by method winding shown in Figure 4, is installed sideslip oil cylinder 3 at last.With loop wheel machine smooth formula hanging beam overhead traveling crane is lifted on two girders 15 of bridge formation machine (as shown in Figure 1), get final product place in operation.
