Please refer to Fig. 6, Fig. 7, Fig. 6 is the local enlarged diagram of main body of vehicle frame leading portion shown in Fig. 5; Fig. 7 is that the A of Fig. 6 is to view.
The inside of main body of vehicle frame leading portion 21 is provided with the symmetrical vertical riser 211 of twice, vertically riser 211 is divided into three box spaces with the inside of main body of vehicle frame leading portion 21, being equivalent to has increased rectangular configuration again in the inside of main body of vehicle frame leading portion 21, by installing vertical riser 211 additional, can effectively improve its structural strength.
Please refer to Fig. 8, Fig. 9, Fig. 8 is the local enlarged diagram of vehicle bridge linkage section shown in Fig. 5; Fig. 9 is that the B of Fig. 8 is to view.
Vehicle bridge linkage section 22 is closed box structure independently, and its inside has a plurality of boxes space.
Particularly, the outer vertical plate 223 of upper cover plate 221, lower shoe 222, both sides encloses the outline that respectively forms the vehicle bridge linkage section from four direction, and by preceding shrouding 224 and back shrouding sealing 225, its inside is provided with symmetrical twice inner vertical plate 226, and inner vertical plate 226 is divided into three box spaces with the inside of vehicle bridge linkage section 22.
The parallel seat board 227 of twice is connected in the inner top of upper cover plate 221, the groove that its two ends that are provided with connecting bore are passed on inner vertical plate 226 and the outer vertical plate 223 extend out to the outside, outer vertical plate 223 is aduncate arc, so that provide enough installing spaces for oil cylinder.
Further, the middle part of lower shoe 222 is provided with the shape of a saddle bent plate 228 between inner vertical plate 226, and inner vertical plate 226 and bent plate 228 are divided into four box spaces with the inside of vehicle bridge linkage section 22.
The multi-box type structure can make the main body of vehicle frame 20 after the combination become the variable section form, can increase the crooked moment of inertia and the torsional moment of inertia of vehicle frame, improves the load-carrying capacity of vehicle frame, thereby satisfies structural strength and rigidity requirement when big stressed.
Please refer to Figure 10, Figure 10 is the running condition reference diagram of vehicle bridge linkage section shown in Fig. 5.
Vehicle bridge linkage section 22 is box-structure independently, after welding was finished, docked with main body of vehicle frame leading portion 21 in the place ahead, and dock with back fixed supporting leg 30 at the rear, when hoisting operation, bearing substantial load from main body of vehicle frame center steering seat ring place and fixed supporting leg place, back; Simultaneously, hoisting crane travels under the lift heavy operating condition, can produce huge impact load to the box-structure at this place from the power on the vehicle bridge.
Please refer to Figure 11, Figure 12, Figure 13, Figure 11 is vehicle bridge linkage section shown in Figure 8 inner structure scheme drawing behind the shrouding before removal; Figure 12 is that the C of Figure 11 is to view; Figure 13 is the decomposing schematic representation of vehicle bridge linkage section shown in Figure 8.
Two inner vertical plates 226 of vehicle bridge linkage section 22 are parallel to outer vertical plate 223, constitute the new trapezoidal box of falling with upper cover plate 221, lower shoe 222, are partitioned into two box space A and box space B simultaneously; Lower shoe 222 forms saddle-shaped box with the bent plate 228 of its top, is partitioned into two box space C and box space D simultaneously.Therefore, vehicle bridge linkage section 22 is the structures that are combined into by a plurality of boxes, can bear more greatly and comparatively complicated load working condition.
Please refer to Figure 14, Figure 14 is the butt joint scheme drawing of main body of vehicle frame leading portion, vehicle bridge linkage section and back fixed supporting leg.
There are at least two seam mutual dislocation to be on the different cross-sectional planes in the seam of main body of vehicle frame leading portion 21 and vehicle bridge linkage section 22.
Particularly, welded separately after main body of vehicle frame leading portion 21, vehicle bridge linkage section 22, the back fixed supporting leg 30, its assembly welding is become an integral body, wherein, the length of the lower shoe 22 of vehicle bridge linkage section 22 is respectively stretched out a part on front and rear direction, the floor length of main body of vehicle frame leading portion 21 and back fixed supporting leg 30 shortens a part accordingly.Arrange like this, butt weld is designed on the different cross-sectional planes, avoided all butt welds to focus on the preceding shrouding 224 and the back shrouding 225 of vehicle bridge linkage section 22, increased the anti-shear ability of weld seam, improve reliability of structure.
Please refer to Figure 15, Figure 16, Figure 15 is the structural representation of the another kind of specific embodiment of crane frame that the utility model provides; Figure 16 is the exploded drawings of crane frame shown in Figure 15.
In the another kind of specific embodiment, main body of vehicle frame 20 is a split-type structural, comprise main body of vehicle frame leading portion 21, vehicle bridge linkage section 22 and main body of vehicle frame back segment 23, wherein vehicle bridge linkage section 22 is the main body of vehicle frame stage casing, all the other structures and such scheme are basic identical, under equal boundary condition, but actv. promotes structural behaviour in control vehicle frame weight.
Certainly, above-mentioned crane frame only is a kind of preferred version, specifically is not limited thereto, and can make pointed adjustment according to actual needs on this basis, thereby obtains different embodiments.For example, the inside of vehicle bridge linkage section 22 is designed to other multi-box type structures, perhaps main body of vehicle frame leading portion 21 is integral structure or the like with vehicle bridge linkage section 22.Because mode in the cards is more, casehistory no longer one by one just here.
Except above-mentioned crane frame, the utility model also provides a kind of hoisting crane, fixed supporting leg 10, back fixed supporting leg 30 and vehicle frame (see figure 5) before comprising, described vehicle frame is a crane frame mentioned above, its main body of vehicle frame 20 leading portions are embedded into preceding fixed supporting leg 10, and main body of vehicle frame leading portion 21 docks with vehicle bridge linkage section 22, and vehicle bridge linkage section 22 docks with back fixed supporting leg 30, all the other structures please refer to prior art, and this paper repeats no more.
More than crane frame provided by the utility model and hoisting crane are described in detail.Used specific case herein principle of the present utility model and embodiment are set forth, the explanation of above embodiment just is used for helping to understand core concept of the present utility model.Should be understood that; for those skilled in the art; under the prerequisite that does not break away from the utility model principle, can also carry out some improvement and modification to the utility model, these improvement and modification also fall in the protection domain of the utility model claim.
