The specific embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the present utility model is elaborated.Should be understood that, the specific embodiment described herein only, for description and interpretation the utility model, is not limited to the utility model.
In the utility model, in the situation that do not do contrary explanation, the noun of locality of use typically refers to the upper and lower, left and right in accompanying drawing as " upper and lower, left and right ".
Referring to Fig. 2 and Fig. 3, the utility model relates to vehicle frame on a kind of excavator, and on this excavator, vehicle frame comprises underframe 1, on underframe 1, is provided with hoisting structure.As can be seen here, adopt and do not have exclusive hoisting structure to compare with upper vehicle frame in prior art, the utility model can carry out lifting operation by above-mentioned hoisting structure, and without the installing hole after some parts of use removing vehicle frame on excavator as interim hoisting structure, simplified the operating process of lifting operation, saved the lifting time and improved lifting efficiency.
Wherein, hoisting structure should comprise the various structures form, and the utility model is not limited concrete form.In embodiment as shown in Figures 2 and 3, hoisting structure can comprise the first hole for hoist 3 and the second hole for hoist 4 that is used in conjunction with to be lifted, and wherein, the first hole for hoist 3 is positioned at the front end of underframe 1, and the second hole for hoist 4 is positioned at the rear end of underframe 1.When carrying out lifting operation, can be respectively in the second hole for hoist 4 of the first hole for hoist 3 of front end and rear end, be connected lifting rope, and by the lifting rope vehicle frame on whole excavator of slinging reposefully.Term " front end " and " rear end " refer in actual mounting structure, and the end that the scraper bowl swing arm is installed on vehicle frame on excavator is front end, i.e. left direction in Fig. 2 and Fig. 3; Otherwise the end that counterweight is installed on vehicle frame on excavator is rear end, i.e. right direction in Fig. 2 and Fig. 3.
Usually, above-mentioned the first hole for hoist 3 and the second hole for hoist 4 can be set directly on underframe 1.Figure, 2 and Fig. 3 shown in embodiment in, on excavator, vehicle frame also includes the riser 2 be fixed on underframe 1.Under this structure, can make the first hole for hoist 3 be arranged on the front end of riser 2, and make the second hole for hoist 4 be arranged on the rear end of riser 2, so that be connected lifting rope at the first hole for hoist 3 with on the second hole for hoist 4, and the lifting rope after connecting not can with upper vehicle frame on parts interfere, be conducive to the carrying out of lifting operation.
Particularly, on excavator of the present utility model, vehicle frame includes two symmetrically arranged risers 2, the front end of each riser 2 is provided with the first hole for hoist 3, and two the first holes for hoist 3 are coaxial, the rear end of each riser 2 is provided with the second hole for hoist 4 simultaneously, and makes two the second holes for hoist 4 coaxial.Be appreciated that two first holes for hoist 3 that will be arranged on front end are set to coaxially, can facilitate same lifting rope simultaneously through two the first holes for hoist 3, to carry out stable lifting.In like manner, two the second holes for hoist 4 also are preferably to coaxial setting.
With further reference to Fig. 2 and Fig. 3, because vehicle frame on excavator need to connect swing arm and the boom cylinder of scraper bowl, for this reason, the front end of riser 2 is provided with swing arm hinge hole 22 and boom cylinder hinge hole 23, to be respectively used to carrying out hinged with swing arm and boom cylinder.When excavator is keeped in repair, owing to not needing to remove swing arm and boom cylinder, thereby in order to prevent that lifting rope in the first hole for hoist 3 and swing arm or boom cylinder from interfering, and the obstruction hanging apparatus, can form protruding pinna 21 at the front end of riser 2, this protruding pinna 21 protrudes forward, and the first hole for hoist 3 is formed on this protruding pinna 21, to facilitate, carries out lifting operation.Preferably, protruding pinna 21, between swing arm hinge hole 22 and boom cylinder hinge hole 23, provides pulling force with the vehicle frame that above makes progress in position.
Referring to Fig. 2 and Fig. 3, for the second hole for hoist 4, in the rear end of riser 2, be fixed with otic placode 5, like this, can make the second hole for hoist 4 be formed on otic placode 5, so that the processing of the second hole for hoist 4 be conducive to improve the intensity of the second hole for hoist 4.
In addition, in prior art, adopt the hole for hoist of counterweight installing hole 24 as rear end while carrying out lifting operation, and the position of counterweight installing hole 24 is lower, this is unfavorable for stably lifting, and has the danger of tumbling.For preventing tumbling, the utility model can be on the rear end of riser 2 mounting plate 6, this installing plate 6 is perpendicular to underframe 1.Under the structure of this installing plate 6, otic placode 5 is fixed on this installing plate 6, just can relatively increase the height of the second hole for hoist 4.Wherein, otic placode 5 can be fixed in several ways, and for example, otic placode 5 can be welded on installing plate 6, but is not limited to the fixed form of welding.
In a preferred embodiment, upper vehicle frame can also include stiffener 7, and this stiffener 7 is fixed in riser 2 and installing plate 6 simultaneously, to improve the intensity of installing plate 6, prevents from installing the deformation such as 6 generation bendings, increases the reliability of whole hoisting structure.
Based on vehicle frame on above-described excavator, the utility model can also relate to a kind of excavator, this excavator generally includes running gear and is arranged on the upper brace on this running gear by pivoting support, this upper brace comprises vehicle frame, wherein, described upper vehicle frame is vehicle frame on above-mentioned excavator.Be appreciated that, because upper vehicle frame belongs to upper brace, simultaneously, upper brace is connected with the running gear of excavator again, therefore, and when being keeped in repair, only need to just the excavator complete machine can be sling by the first hole for hoist 3 and the second hole for hoist 4, and, without removing any parts, effectively saved maintenance time, improved maintenance efficiency.
Below describe by reference to the accompanying drawings preferred embodiment of the present utility model in detail; but; the utility model is not limited to the detail in above-mentioned embodiment; in technical conceive scope of the present utility model; can carry out multiple simple variant to the technical solution of the utility model, these simple variant all belong to protection domain of the present utility model.
It should be noted that in addition, each concrete technical characterictic described in the above-mentioned specific embodiment, in reconcilable situation, can be combined by any suitable mode, for fear of unnecessary repetition, the utility model is to the explanation no longer separately of various possible combinations.
In addition, between various embodiment of the present utility model, also can carry out any combination, as long as it is without prejudice to thought of the present utility model, it should be considered as content disclosed in the utility model equally.
