2.In addition, the first weld seam 620 sentences the first radius 600 and the second radius 602 rounding at each end.Second weld seam 622 is limited to the 4th welding position 528 place between the second plate 508 and the 3rd plate 510 on the outside 700 of the first i beam assembly 400.Second weld seam 622 can relative to the angled θ of vertical axis
1.In addition, the second weld seam 622 can sentence the 3rd radius 604 and the 4th radius 606 rounding in every one end.
The first weld seam 620 in figure 6 and the shape of the second weld seam 622 can be designed to respective welding position is positioned at the most low stress position along i beam assembly.Minimum stress position such as can based on the weight of counterweight, especially because each i beam assembly is designed to transmit from counterweight 126 load to gantry pillars and pivot 108.Such as, in i beam assembly, induce the finite element analysis of the stress of generation, different angle θ may be produced having between the machine of 9500 kilograms of counterweights and the machine with 10000 kilograms of counterweights
1and θ
2and radius.Under any circumstance, as shown in Figure 6, solder joint is angled relative to each corresponding vertical axis, and every rounded angle, one end.
In a nonrestrictive example, angle θ
1can be large between 5-30 °, and angle θ
2can be large between 10-50 °.In another example, angle θ
1can be large between 10-20 °, angle θ
2can be between about 20-30 °.In further example, angle θ
1can be between about 10-15 °, angle θ
2can be between about 22-28 °.As mentioned above, each angle can be different according to the size of counterweight 126.
The load carrying out Self-counterweight 126 can make the first weld seam 620 at first radius 600 place's tension and the first weld seam 620 at the second radius 602 place pressurized.Similarly, identical load can cause the second weld seam 622 in the 3rd radius 604 place tension and cause the second weld seam 622 at the 4th radius 606 place pressurized.Consequently, the first radius 600 can be different along the first weld seam 620 from the second radius 602, and the 3rd radius 604 can be different along the second weld seam 622 from the 4th radius 606.
In one non-limiting embodiment, the first radius 600 can be large between 200-300 millimeter, and the second radius 602 can between about 20-100 millimeter.In another example, the first radius 600 can be large between 225-275 millimeter and the second radius 602 can between about 20-60 millimeter.In further example, the first radius 600 can be at least 225 millimeters and the second radius 602 can be at least 30 millimeters.
One different, in nonrestrictive example, the 3rd radius 604 can be large between 200-300 millimeter and the 4th radius 606 can be large between 20-100 millimeter.In another example, the 3rd radius 604 can be large between 225-275 millimeter and the 4th radius 606 can be between about 60-80 millimeter.In further example, the 3rd radius 604 can be at least 225 millimeters and the 4th radius 606 can be at least 60 millimeters.In these embodiments, the first radius 600 and the 3rd radius 604 can be roughly the same in certain embodiments, but also can be different in other example.Similarly, the second radius 602 and the 4th radius 606 can be basic simlarity in certain embodiments, and can be different in other example.As mentioned above, the size of counterweight 126 can affect the Angle Position of weld seam and the radius of each rounding end.
Another aspect of i beam assembly is its height.For object of the present disclosure, show two height of i beam assembly in figure 6.As shown in the figure, the first i beam assembly 400 comprises the first height H
1with the second height H
2.In the disclosure, i beam height is called as the first height H
1the second height H is called as with the height of cantilever pin pin (foot pin)
2.First height or i beam height are limited near far-end 418 and between the end face of i beam assembly 400 and bottom surface.Second height or the height of cantilever pin pin to be limited near near-end 416 and between the bottom of i beam assembly 400 and cantilever pivot axis 404 (that is, at the first pivot position 302 place).The bottom of the first i beam assembly 400 also can be associated with the bottom surface of upper frame 102, for determining the first height and the second height.
In many conventional excavators, second height or cantilever pin pin height roughly the same or consistent in the identical dimension of excavator or kind of different manufacturer.Such as, the cantilever pin pin height of 48 tonnes of excavators is roughly the same in multiple excavator manufacturers.Similarly, the height of the cantilever pin pin of 36 tonnes of excavators is roughly the same in most of excavator manufacturers.A reason of this similitude is because cantilever pin pin height takes the kinematics factor of the front end of machine into account.Especially, the height correlation that cantilever pin pin height and machine can reach, such as, scraper bowl 124 can reach many high or how far.In the situation of many excavators, the excavation of machine and to stretch out specification be during the multiple designs considered when planing machine are considered two.Excavating specification can be roughly the same for most conventional excavator, and therefore when when cantilever pin pin height is roughly the same in most conventional excavator, this similitude is not hard to predict.
First or i beam height H
1can increase when the size of machine increases, but cantilever pin pin height H
2also can increase when the size of machine increases.Therefore, even if when machine dimensions changes, i beam height H
1with to cantilever pin pin height H
2ratio roughly the same.Such as, for the excavator between 14 tonnes and 36 tonnes, i beam height H
1with cantilever pin pin height H
2ratio between difference can be less than 0.10.
In another embodiment, for the excavator of different brackets in the market, i beam height H
1with cantilever pin pin height H
2ratio ranges between 0.24 to 0.30.In other words, in different excavator grade (that is, between 14 tonnes and 36 tonnes), described ratio keeps constant substantially, even if i beam height H
1with cantilever pin pin height H
2all increase when machine dimensions increases.
The layout restriction i beam height of the upper frame of the excavator of most conventional.Such as, in most conventional excavator, only have single motor, and motor is arranged on the top of two conventional i beams.Especially, motor to be installed on i beam and towards the far-end (that is, near counterweight) of i beam.In such an embodiment, the countershaft of motor is arranged perpendicular to i beam usually.In some replaceability structure, the countershaft of motor is configured to be parallel to i beam.
Conventional excavator be designed so that it expects motor to be installed to upper frame usually as far as possible lowly.In fact, which has limited the height of conventional i beam assembly.When the countershaft of motor is set up perpendicular to i beam, i beam height is by the position limitation of the bottom of motor.When the countershaft of motor is parallel to i beam layout, the demand of the accessibility of the height-limited side in maintenance motor of i beam, for maintenance process simulation.But conventional i beam assembly also needs the minimum constructive height for supporting counterweight.In addition, because the i beam height of conventional i beam assembly is lowered, thus the thickness of conventional i beam or plate increases to support counterweight further.Therefore, conventional excavator is generally designed to the conventional i beam comprising and have minimum constructive height and thicker plate.
But in the disclosure, upper frame 102 is redesigned to comprise two motors.More specifically, as shown in Figure 4, the layout of upper frame 102 redesigns, and fuel tank 212 and hydraulic fluid tank 214 are positioned between the first i beam assembly 400 and the second i beam assembly 402.Although i beam is not shown in Figure 2, first motor 200 and the second motor 202 are positioned to the outside 700 of the first i beam assembly 400, and therefore motor is neither positioned at the top of any one i beam assembly, be not installed to any one i beam assembly yet.Fuel tank 212 and hydraulic fluid tank 214 can be installed to one in multiple frame supported plate 410, and thus there is not the corresponding structure of the height of restriction first and second i beam assembly.
Consider the upper frame layout of Fig. 2, the first i beam assembly 400 and the second i beam assembly 402 can comprise first or i beam height H of increase
1.Although many above-mentioned conventional i beams comprise because motor is mounted thereon the i beam height being less than 250 millimeters, and the first i beam assembly 400 of the present utility model and the second i beam assembly 402 can comprise the i beam height of about 700 millimeters.In order to object of the present disclosure, the first i beam assembly 400 and the second i beam assembly 402 can be called as " high i beam "." high I-shaped beam assembly " or " high i beam " may be defined as so a kind of i beam assembly, and this i beam assembly has the i beam height H between 0.5 to 1.0
1with cantilever pin pin height H
2ratio.Therefore, the i beam height H of the first i beam and the second i beam
1with cantilever pin pin height H
2ratio can be the first i beam height H of above-mentioned conventional i beam
1with cantilever pin pin height H
2about twice or more of ratio.
In a nonrestrictive example, table 1 below illustrates the height H of the i beam for a series of excavators in the market
1with the height H of cantilever pin pin
2ratio.
Table 1: the ratio of i beam height and cantilever pin pin height
| Machine Type | Ratio |
| 14 tonnes, conventional i beam | 0.30 |
| 16 tonnes, conventional i beam | 0.27 |
| 21 tonnes, conventional i beam | 0.28 |
| 24 tonnes, conventional i beam | 0.26 |
| 29 tonnes, conventional i beam | 0.24 |
| 36 tonnes, conventional i beam | 0.29 |
| 48 tonnes, high i beam | 0.72 |
As shown in table 1, i beam height H
1with cantilever pin pin height H
2ratio when use high i beam can be larger significantly.The ratio of 0.72 is only an example, and can be different for dissimilar machine, especially those machines that may comprise different weight size or have different excavations or extend specification.
The ratio obtained by using higher I beam may be different, to reach best intensity and weight characteristic.Such as, the plate that higher i beam can also allow multiple plate to form conventional i beam than those is thinner.Such as, the first plate 506, second plate 508 and the 3rd plate 510 can comprise the thickness of reduction compared with plate similar on conventional i beam.The combination (that is, forming multiple plates of i beam assembly) of the i beam assembly of thinner plate and segmentation can reduce the gross weight of i beam assembly, and strengthens the upper frame 102 of machine 100 further.
Although adopt the exemplary embodiment of principle of the present utility model as above open, the utility model is not limited to the disclosed embodiments.On the contrary, the application is intended to cover and uses of the present utility model any change of its General Principle, use or amendment.In addition, the application is intended to cover to of the present disclosure within the scope of the known of field belonging to present disclosure or usual practice and fall into such departing from the scope of claims.
