Technical field
The utility model relates to the traveling mechanism of the larger traveller of goliath crane, specifically a kind of traveling mechanism of the larger traveller secondary equalizer bar and three grades of free bearing devices that can separate fast that equalizer bar is hinged of being used for.
Background technique
In the traveling mechanism of the larger traveller of goliath crane, because the machining error of wheel, vehicle frame and the unequal factor of big Car Track, each wheel is slightly variant with the point of contact of big Car Track in vertical direction.For the carrying size of each wheel of balance, generally adopt three grades of equalizer bar structures, set of wheels is installed on nethermost a plurality of three grades of equalizer bars, each three grades of equalizer bar is hinged on the secondary equalizer bar by free bearing.When set of wheels on three grades of equalizer bars of maintenance and driving mechanism, three grades of equalizer bars and secondary equalizer bar need be taken apart.
Existing free bearing as shown in Figure 1 and Figure 2, comprise and be fixed on the last free bearing 1 on the secondary equalizer bar and be fixed on following free bearing 6 on three grades of equalizer bars, be processed with corresponding whole fraising on two blocks of side plates of last free bearing 1 and on two blocks of side plates of following free bearing 6 respectively, two blocks of side plates of following free bearing 6 are positioned at two blocks of side plates of free bearing 1, in the integral body fraising of hinge 2 through last free bearing 1 and following free bearing 6, its end is fixed with end cap 3 by bolt 4 and elastic washer 5, and the flange of end cap 3 is pressed on the side plate of free bearing 1.Because the hinge 2 in the free bearing has micro-distortion after bearing shearing, extrusion load, the distortion of this trace brings very burden can for the dismounting of hinge 2, need be by jack, welding upper frame, dismounting hinge 2 often needs for a long time, and upper frame is welded in the outward appearance that also influences hoist on the vehicle frame.
Summary of the invention
The utility model provides a kind of free bearing device that can separate fast at the problems referred to above, and this free bearing device distortion is little, and convenient disassembly can separate fast.
According to the technical solution of the utility model: a kind of free bearing device that can separate fast, comprise by the hinged last free bearing of hinge and reach free bearing down, two blocks of side plates of described upward free bearing are corresponding with two blocks of side plates of described free bearing down respectively, described upward free bearing and the described junction point of two blocks of side plates up and down of free bearing the same side down are provided with the gap, have the fraising of the cross section that matches with described hinge on described two blocks of side plates up and down of going up free bearing and described time free bearing the same side less than semicircle, the axial outer end of described fraising is provided with boss, described upward free bearing and described two described boss of free bearing the same side down are sleeved in the end cap, and described end cap is fixed on the axle head of described hinge.
Described end cap is fixed on the axle head of described hinge by bolt and elastic washer.
Described bolt and described elastic washer have two covers.
Described upward free bearing is identical with described free bearing structure down, size is identical.
Technique effect of the present utility model is: going up free bearing in the utility model is the subdivision structure with following free bearing, can separate easy installation and removal fast; Fraising under last free bearing reaches on the free bearing is semicircle pylon structure, can bear the extrusion load of bigger Vertical direction; Hinge only bears vertical extruding, is out of shape little; Last free bearing is interchangeable with following free bearing, is convenient to reduce the kind of component.

Embodiment
Below in conjunction with accompanying drawing embodiment of the present utility model is further described.
Among Fig. 1 ~ Fig. 5, comprise free bearing 1, hinge 2, end cap 3, bolt 4, elastic washer 5, free bearing 6, boss 7, side plate 8, gap 9, fraising 10 etc. down.
As Fig. 3, Fig. 4 and shown in Figure 5, the utility model is a kind of free bearing device that can separate fast, comprises by hinge 2 hinged last free bearings 1 reaching free bearing 6 down.Free bearing 6 was welded on the base plate by two blocks of parallel side plates 8 and constitutes under last free bearing 1 reached.
In the utility model, two blocks of side plates 8 of last free bearing 1 are corresponding with two blocks of side plates 8 of following free bearing 6 respectively, are the subdivision structure.Last free bearing 1 is provided with gap 9 with the junction point of two blocks of side plates 8 up and down of following free bearing 6 the same sides.The purpose that gap 9 is set is to produce interference when preventing that free bearing 1 and following free bearing 6 from relatively rotating.
Have the fraising 10 of the cross section that matches with hinge 2 on two blocks of side plates 8 up and down of last free bearing 1 and following free bearing 6 the same sides less than semicircle, the axial outer end of each fraising 10 is provided with boss 7, last free bearing 1 is sleeved in the end cap 3 with two boss 7 of following free bearing 6 the same sides, end cap 3 is fixed on the axle head of hinge 2 by bolt 4 and elastic washer 5, and hinge 2 axially can not gone here and there.
The bolt 4 and the elastic washer 5 at hinge 2 two ends can be provided with a cover, also two covers can be set.
Last free bearing 1 in the utility model and following free bearing 6 can make that structure is identical, size is identical, interchangeable, are convenient to reduce the kind of component.
When the utility model used, last free bearing 1 was fixed on the secondary equalizer bar of goliath crane traveling mechanism of the larger traveller, and following free bearing 6 is fixed on three grades of equalizer bars, formed hinging structure by hinge 2.The extrusion load of Vertical direction is delivered to hinge 2 by the fraising 10 of last free bearing 1, is delivered to down in the fraising 10 of free bearing 6 by hinge 2 again, and following free bearing 6 is delivered on the crane set of wheels again.Fraising 10 under last free bearing 1 reaches on the free bearing 6 is semicircle pylon structure, can bear the extrusion load of bigger Vertical direction.2 of hinges bear vertical extruding, are out of shape very little.
Tensional load of the present utility model only is the weight load of cart set of wheels self, and is smaller, can transmit tensional load by the end cap 3 in the round boss that is embedded into 10 ends of reaming up and down.
The utility model when dismounting, only need pull down the bolt 4 on end cap 3 end faces at hinge 2 two ends, take out the two ends end cap 3 that embeds in the annulus boss 7, last free bearing 1 can separate easy installation and removal fast with following free bearing 6.
