Abstract
The utility model discloses an enhanced type bucket rod of an excavator, belongs to engineering machinery and aims at providing an excavator bucket rod which is long in service life and good in continuous operation performance. The enhanced type bucket rod comprises a rod body in a box-shaped structure, wherein the rod body is formed by a bucket hinge support (1), two front lateral plates (5), a front lower cover plate (6), an upper cover plate (13), two rear lateral plates (7), a rear lower cover plate (8), a rear upper cover plate (12) and a cover plate (11). Two lug plates (10) are welded to the cover plate (11) and the rear upper cover plate (12), one front shaft seat (2) is respectively welded to the two front lateral plates (5), a rear shaft seat (9) is respectively welded to the two rear lateral plates (7), an enhanced plate (3) is respectively welded to the two front lateral plates (5), and a bottom enhanced plate (14) is welded to the front lower cover plate (6). The enhanced type bucket rod of the excavator has the advantages of being high in strength, good in rigidity, long in service life and the like, and can meet the requirements for continuous operation.
Description
Technical field: the utility model relates to a kind of excavator, relates in particular to a kind of excavator boom.
Background technology: dipper is one of three big ingredients of digger operating device, and its front end and scraper bowl are hinged, rear end and swing arm are hinged; Can realize various excavation actions through the flexible dipper that makes of bucket arm cylinder around rotating with the swing arm pin joint.At present, the otic placode of common dipper is split type welded construction, and its more weld seam not only causes welding stress to concentrate easily, and when working continuously, dipper receives the continuous impact of fluctuating load and is prone to take place fatigue failure, cracks or ruptures.In addition, the impact force that axle bed and position of articulating point receive is bigger, takes the lead in occurring fatigue fracture easily; Moreover, the dipper bottom often and ground dawdle and inefficacy easy to wear.
Summary of the invention: to the above-mentioned defective that exists in the prior art, the reinforced dipper of the excavator that the utility model aims to provide a kind of long service life, the performance of working continuously is good.
To achieve these goals; The utility model adopts following technical scheme: it comprises the body of rod of box structure, this body of rod by the bucket hinged-support, respectively be welded on two front side boards at these bucket hinged-support two ends, respectively be welded on this two front side boards bottom and top and with the preceding lower cover of bucket hinged-support welding and upper cover plate, respectively with two back side panels of two front side boards welding, be welded on this two back side panels bottom and with the back lower cover of preceding lower cover welding, be welded on this two back side panels top and with the back upper cover plate of preceding upper cover plate welding, be welded on two back side panel front ends and the cover plate that welds with back upper cover plate and back lower cover respectively constitutes; Two otic placodes are welded on cover plate and the back upper cover plate, on two front side boards, respectively are welded with a preceding axle bed, axle bed after respectively being welded with on two back side panels; On two front side boards, respectively be welded with a stiffener, be welded with bottom stiffener at preceding lower cover.
On bottom stiffener, be provided with many reinforcing ribs.
Compare with prior art, the utility model substitutes split type otic placode owing to adopted technique scheme with the monolithic otic placode, has therefore reduced weld seam quantity, has eliminated most of welding stress; In addition, because the bucket hinged-support, significant points such as forward and backward axle bed all adopt the thickening foundry goods, therefore can improve the intensity and the reliability of each hinge of dipper; Owing to increased stiffener and bottom stiffener, so body of rod structure is more firm; Be located at reinforcing rib on the bottom stiffener and can improve the abrasion resistance of dipper bottom, effectively prevent wearing and tearing and cause the dipper matrix to damage.
Description of drawings:
Fig. 1 is the structural representation of the utility model;
Fig. 2 is the vertical view of Fig. 1;
Fig. 3 is that A among Fig. 1 is to view.
Among the figure: upper cover plate 13 bottom stiffeners 14 before the axle bed 2 stiffeners 3 reinforcing ribs 4 front side boards 5 preceding lower cover 6 back side panels 7 back lower covers 8 back axle beds 9 otic placodes 10 cover plates 11 back upper cover plates 12 before the bucket hinged-support 1
The specific embodiment: the utility model is described further below in conjunction with accompanying drawing and concrete embodiment:
Can know by Fig. 1～3, the body of rod of box structure by bucket hinged-support 1, respectively be welded on these bucket hinged-support two ends two front side boards 5, be welded on this two front side boards bottom and with the preceding lower cover 6 of bucket hinged-support 1 welding, be welded on this two front side boards top and with the preceding upper cover plate 13 of bucket hinged-support 1 welding, two back side panels 7 that are welded to connect with two front side boards 5 respectively, be welded on this two back side panels bottom and the back lower cover 8 that is welded to connect with preceding lower cover 6, be welded on this two back side panels top and the back upper cover plate 12 that is welded to connect with preceding upper cover plate 6, be welded on two back side panels, 7 front ends and respectively with back upper cover plate 12 and after the cover plate 11 that is welded to connect of lower cover 8 constitute.The otic placode 10 of two U fonts is welded on the cover plate 11, and an openend of each otic placode 10 extends forward and is welded on the upper cover plate 12 of back.On two front side boards 5, respectively be welded with a preceding axle bed 2, axle bed 9 after respectively being welded with on two back side panels 7; On two front side boards 5, respectively be welded with a stiffener 3, be welded with bottom stiffener 14 at preceding lower cover 6.For intensity and the rigidity that improves the body of rod, on bottom stiffener 14, be provided with many reinforcing ribs 4.
