The specific embodiment
Fig. 3 is the block diagram of the utility model quarry tipper gantry beam embodiment; Fig. 4 is the structural representation of bottom girder in Fig. 3; Fig. 5 is the structural representation of back timber in Fig. 3; Please refer to Fig. 3-5, the present embodiment provides a kind of quarry tipper gantry beam, comprises bottom girder 31, on bottom girder 31, button is provided with a back timber 32, back timber 32 comprises that 321, two supporting legs 321 of two supporting legs are supported in respectively on bottom girder 31 end faces 310, and back timber 32 and bottom girder 31 surround a through hole 30; On the end face of bottom girder 31 and two supporting leg 321 inner sides, be formed with respectively 33, two lug bosses 33 of two lug bosses respectively and between corresponding supporting leg 321, form the space of passing for longeron.
Particularly, it is microscler that bottom girder 31 can be, and can there is the end face of level, back timber 32 can be " door " font or arch, the adjustable brace 32 that two stretches out can be supported on respectively the end face two ends of bottom girder 31, so that back timber 32 and bottom girder 32 surround a closed circular jointly, the hollow space of this closed circular is through hole 30.
On the end face of bottom girder 31, the supporting leg 321 of opposite ends epirelief formation lug boss 33 is respectively formed with arc groove 315 on bottom girder 31 and between two lug bosses 33; Certainly, lug boss 33 can and be fixed on bottom girder 31 end faces by modes such as welding for individual components, and two lug bosses 33 form space with the supporting leg 321 of corresponding one end respectively; Between the height (being the distance of lug boss 33 higher than bottom girder 31 end faces) of lug boss 33 and lug boss 33 and corresponding supporting leg 321, forming space all can determine according to the size of longeron, for example, lug boss 33 can equal longeron along horizontal width apart from the distance of supporting leg 321 in its outside, and the height of lug boss 33 can be less than or equal to longeron 2(as shown in Figure 6) along vertical height; And the distance between two lug bosses 33 can be determined according to the distance between two longerons, to guarantee two longerons space through the supporting leg 321 of lug boss 33 and corresponding end respectively.
Fig. 6 is the assembling schematic diagram between quarry tipper gantry beam and longeron embodiment illustrated in fig. 3; Please refer to Fig. 3-6, back timber 32 is only supported on bottom girder 31 end faces, and both are not directly fixedly connected with in this support place; Like this, in the time of assembling, can first bottom girder 31 be lifted into easily to longeron 2 places, and the vertical bottom girder 31 of longeron 2 is penetrated in two spaces that two lug bosses 33 and two end supports leg 321 form, because lug boss 33 and supporting leg 321 only carry out spacing to the both sides of longeron 2, longeron 2 can enter into this space by top, greatly facilitates operation; After the relative position centering of bottom girder 31 and longeron 2, can again back timber 32 be lifted into bottom girder 31 tops, and make two supporting legs 321 of back timber 32 support to respectively the outside of bottom girder 31 end faces, longeron 2, finally, the surface of longeron 2 is welded and fixed with end face, the lug boss 33 of bottom girder 31 and the supporting leg of back timber 32 of bottom girder 31 respectively, thereby completes being relatively fixedly connected with between back timber 32, bottom girder 31 and longeron 2.
The quarry tipper gantry beam that the present embodiment provides, by adopting the split-type structural of back timber and bottom girder, can realize first lift bottom girder, easily longeron and bottom girder are assembled together after, lift again back timber, easily back timber, bottom girder and longeron be assembled into together, greatly facilitate assembly process, can effectively guarantee to be welded and fixed the Joint strenght between rear back timber and gantry beam simultaneously; And the fabrication properties of back timber, bottom girder is better, and can relax the requirement to gantry beam working accuracy, be conducive to save the tooling cost of gantry beam.
Further, back timber 32 also comprises and is formed at two linkage sections 322 between supporting leg 321 tops; On linkage section 322, be fixedly installed the top locations 313 protruding towards bottom girder 31, and top locations 313 matches to the distance between bottom girder 31 end faces and the height of longeron 2; That is to say, top locations 313 can equal the height of longeron 2 to the distance of supporting leg 321 ends, thereby make to support to behind bottom girder 31 end face two ends at back timber 32, distance between the end face 310 of top locations 313 and bottom girder 31 equals the height of longeron 2, further to determine the relative position between longeron 2 and back timber 32 by this top locations 313 on vertical; And then, in the time of follow-up welding, the bottom surface of longeron 2 can and end face 310 weld togethers of bottom girder 31 between lug boss 33 and supporting leg 321, the both sides of longeron 2 can be respectively with together with the surface soldered of lug boss 33 and supporting leg 321, more reliable, firm being fixedly connected with between longeron 2 and gantry beam realized together with can being welded and fixed with top locations 313 in the top of longeron 2.
Preferably, back timber 32 can be steel structure group welding piece, and linkage section 322 can extend along straight line, and linkage section 322 bearing of trends are perpendicular to supporting leg 321; Linkage section 322 tops also can fixedly be coated with upper cover plate 34; Similarly, bottom girder 31 can be also steel structure group welding piece, and bottom girder 31 has plane end face and bottom surface, and the bottom surface of bottom girder 32 is fixedly coated with lower cover, to improve loading strength.And flat upper cover plate 34 and lower cover processing are more convenient, and cost is lower.
Further, the outside of back timber 32 also can be fixedly installed and be useful on the first bearing 41 that connects oil cylinder; The two ends of bottom girder 31 are also fixedly installed respectively and are useful on the second bearing 42 that connects transversal swinging arm.Particularly, on the first bearing 41, can offer connecting through hole, oil cylinder can pass by connecting pin the pin joint of this connecting through hole realization and the first bearing 41; Similarly, the second bearing 42 also can be established connecting through hole, for swing arm by connecting pin and the second bearing 42 pin joints.The foundry goods that the first bearing in the present embodiment and the second bearing can be made for foundry technique, to make it have good intensity, and then guarantees intensity and the reliability that pin connects.
The utility model another embodiment provide a kind of carriage of mining self-unloading vehicle, please refer to Fig. 6, comprise: the as above quarry tipper gantry beam described in arbitrary embodiment, at least two longerons that extend longitudinally 2, and some crossbeams, wherein, longeron 2 can be horizontally disposed with, and gantry beam can be perpendicular to longeron 2 and along horizontally set; Two longeron 2 spaces through lug boss 33 and the supporting leg 321 of this quarry tipper gantry beam respectively, and longeron 2 surfaces are welded and fixed with lug boss 33 and supporting leg 321 respectively; Wherein, the concrete structure of quarry tipper gantry beam and function and previous embodiment are similar, repeat no more herein.
Carriage of mining self-unloading vehicle in the present embodiment, its gantry beam adopts the split-type structural of back timber and bottom girder, can realize first lift bottom girder, easily longeron and bottom girder are assembled together after, lift again back timber, easily back timber, bottom girder and longeron be assembled into together, greatly facilitate assembly process, can effectively guarantee to be welded and fixed the Joint strenght between rear back timber and gantry beam simultaneously; And the fabrication properties of back timber, bottom girder is better, and can relax the requirement to gantry beam working accuracy, be conducive to save the tooling cost of gantry beam.
