The specific embodiment
Please with reference to Fig. 3 and Fig. 4, the cross-sectional plane of crane frame 100 of the present invention adopts quadrangular section, for example rectangle, isosceles trapezoid, and four limits in cross section are made up of upper cover plate 20, lower cover 30, two coxostermums 40.Describe for convenient, upper cover plate 20, lower cover 30, two coxostermums 40 can be commonly referred to as the side plate that constitutes vehicle frame 100 shells.Vehicle frame 100 inside are provided with some dividing plates 50 and some reinforced plates 60, the structure that is used to reinforce vehicle frame 100.Four limits of dividing plate 50 are connected with upper cover plate 20, lower cover 30 and two coxostermums 40 respectively, and a plurality of dividing plates 50 are arranged on vehicle frame inside, and are provided with at interval between a plurality of dividing plate 50.
A plurality of reinforced plates 60 are bending plate and are arranged between vehicle frame 100 in-to-ins two adjacent separator 50; A plurality of reinforced plate 60 distributed and arranged are on side plate 20,30,40; Side plate 20/30/40 is strengthened, and at present embodiment, the inboard of upper cover plate 20 and two coxostermums 40 all is provided with reinforced plate 60.Front and back two ends of each reinforced plate 60 are captiveed joint with two adjacent dividing plates 50 respectively, and two sides of each reinforced plate 60 are fixedly connected on the connected same side plate 20/30/40.At present embodiment, each reinforced plate 60 is the U-shaped bending plate, comprises the adapter plate 62 of two bendings and connecting panel 63, two adapter plates 62 that are connected between two adapter plates 62 are captiveed joint with cooresponding same side plate 20/30/40.Front and back two ends of adapter plate 62 and connecting panel 63 are captiveed joint with two adjacent dividing plates 50 respectively.
In practical application, upper cover plate 20 easy pressurizeds, lower cover 30 is drawn easily, and two coxostermums 40 are pressurized up and down then.Yet no matter be pressurized or drawn that the middle part distortion of side plate 20,30,40 is the most serious.Therefore, in preferred version, reinforced plate 60 covers the center line of side plate 20,30,40, to prevent that more effectively side plate 20,30,40 is because of being out of shape excessive the inefficacy.
Above-mentioned side plate 20,30,40, dividing plate 50, the connection mode between the reinforced plate 60 can adopt welding.On dividing plate 50 and lower cover 30, offer hole 90, the cavity that hole 90 is communicated with between dividing plates 50 and the dividing plate 50 is so that the welder gets into vehicle frame 100 interior welds.
According to the needs of structure transmission power, the cross-sectional plane of reinforced plate 60 can change.Fig. 5 and Fig. 6 show reinforced plate 60 various structure, show among Fig. 5 this reinforced plate 60 about two sides be parallel to each other, and Fig. 6 has shown that reinforced plate 60 ' downside has one section to be hypotenuse in another kind of embodiment.
Be appreciated that reinforced plate 60,60 ' can be formed by a whole plate bending, also can be spliced through the mode of polylith plate through welding.
Compare the endosternum of prior art; Reinforced plate of the present invention 60,60 ' is in light weight; Occupation space is little, not only can reduce the weight of vehicle frame 100, and has increased the inner space of vehicle frame 100; Thereby some parts on more or bigger chassis can be installed, for example transmitter shaft, storage tank, hydraulic tubing, electric wiring etc.
Be appreciated that in order further to reduce reinforced plate 60,60 ' weight, can perforate 64 on reinforced plate 60,60 ' connecting panel 63, the shape in hole 64 and position can be confirmed according to the distribution of stress of vehicle frame 100.
In another embodiment, please with reference to Fig. 7 and Fig. 8, upper cover plate 20 and two coxostermums 40 are provided with reinforced plate 70, and lower cover 30 is provided with two reinforced plates 80.Front and back two ends of each reinforced plate 70,80 are captiveed joint with two adjacent dividing plates 50 respectively, for example adopt the mode captive joint of welding, and two sides of each reinforced plate 70,80 are fixedly connected on the connected same side plate 20/30/40.At present embodiment, the middle part of reinforced plate 70 is broken off and is formed two sides that two L shaped stiffening piece 71, two stiffening pieces 71 are arranged symmetrically in upper cover plate 20 and two coxostermums, 40 center lines.Each L shaped stiffening piece 71 comprises fixed plate 72 and dag 74; Fixed plate 72 is fixed on upper cover plate 20 or two coxostermums 40; Two fixed plates 72 of two L shaped stiffening pieces 71 of each reinforced plate 70 are fixedly connected on the same side plate 20/40; The dag 74 of two L shaped stiffening pieces 71 on the same side plate 20/40 can be established dorsad, shown in upper cover plate 20; Also can establish in opposite directions, shown in two coxostermums 40.Two reinforced plates 80 on the lower cover 30 are the V-arrangement bending plate, relatively the center line symmetric arrangement of lower cover 30.
The quantity and the array mode that are appreciated that reinforced plate 60,60 ', 70,80 can come to decide as required.
Among the present invention, on any limit of the cross-sectional plane of vehicle frame 100, increase reinforced plate 60,60 ', 70,80 pair of this limit strengthened.This arrangement improved the moment of inertia of cross section at vertical and horizontal around material being arranged into as far as possible, thereby improved the effect of material aspect stressed.
The present invention also provides a kind of hoisting crane, and it comprises above-mentioned crane frame 100.All the other structures of this hoisting crane can not given unnecessary details at this referring to prior art.
The above only is embodiments of the invention, is not the present invention is done any pro forma restriction; Though the present invention discloses as above with embodiment; Yet be not in order to limiting the present invention, anyly be familiar with the professional and technical personnel, in not breaking away from technical scheme scope of the present invention; When the technology contents of above-mentioned announcement capable of using is made a little change or is modified to the equivalent embodiment of equivalent variations; In every case be not break away from technical scheme content of the present invention, to any simple modification, equivalent variations and modification that above embodiment did, all still belong in the scope of technical scheme of the present invention according to technical spirit of the present invention.
