Abstract
The utility model discloses wear plates connected with side edges of an excavator bucket. The side edges are respectively arranged on outsides of two ends of the bucket, the wear plats are respectively arranged on the inner side of two end plates of the bucket and fixedly connected with the same, positions of the wear plate correspond to those of the side edges, the wear plates are provided with a plurality of through holes, the shape of each through hole matches with shapes of heads of fastening bolts, the fastening bolts penetrate through the wear plates, the bucket end plates and the side edges sequentially from the insides of two ends of the bucket, and the side edges and the bucket end plates are connected integrally by aid of fastening nuts. The wear plates are simple in structure and convenient and practical. The two wear plates are respectively fixedly arranged on the inner sides of the end plates at two ends of the bucket, the side edges of the bucket can be positioned and fixed by the fastening bolts when assembling, and the bolts can not rotate following the nuts when the nuts are screwed on. During usage of the bucket, the side edges can be replaced even when the heads of the fastening bolts are abraded, thereby bringing convenience to assemble and repair the side edges.
Description
Technical field
The utility model relates to the bindiny mechanism of a kind of power shovel side edge and scraper bowl, especially a kind of securing member that connects side edge and scraper bowl that both can prevent takes place loosening, can prevent the long-term junction plate that uses the back fastener head that wearing and tearing take place and can't dismantle again, belong to technical field of engineering machinery.
Background technology
At present, the engineering machinery particularly installation of power shovel side edge adopts bolt, nut fastening usually, and in order to prevent bolt looseness, the screw-down torque that needs is bigger, and at this moment, bolt or nut tend to follow rotation, causes bolt, the fastening effect of nut bad.In order to prevent bolt or nut transfer, in most cases use spanner or special tool that the bolt turret head is fixedly tightened, when tightening, the instrument of anchor stud head often because overcoming the transfer of bolt is stuck, has brought certain trouble to assembling.Because the operating mode that scraper bowl uses is more abominable, hard objects such as many and rock are collided in the work, after using a period of time, because of the fixing bolt head of scraper bowl side edge is worn can't demounting bolt, have to slice off bolt head the certain difficulty of bringing for maintain and replace scraper bowl side edge with gas cutting tool.
The utility model content
The purpose of this utility model provides a kind ofly can guarantee that the power shovel side edge is connected reliably with the scraper bowl end, prevents that connecting bolt is loosening, and still can dismantle the wear strip of power shovel connecting bolt after long-term the use.
The utility model is achieved by the following technical programs:
The wear strip that a kind of power shovel is connected with side edge, described side edge lay respectively at the outside, scraper bowl two ends, and described wear strip lays respectively at the inboard of scraper bowl two end plates, fixedlys connected with two end plates; Described wear strip position is corresponding with described side edge position, described wear strip is provided with several through holes, described through hole and fastening bolt nose shape coupling, described fastening bolt is inboard from the scraper bowl two ends respectively successively to pass wear strip, scraper bowl end plate, side edge, by clamp nut side edge and scraper bowl end plate is linked into an integrated entity.
The purpose of this utility model can also further realize by following technical measures.
The wear strip that aforesaid power shovel is connected with side edge, the overall size of through hole is than the big 2～3mm of fastening bolt head dimensions on the wherein said wear strip.
The utility model is simple in structure, convenient and practical.The utility model fixedly installs a wear strip in the end plate inboard at scraper bowl two ends respectively, and this wear strip is provided with the through hole with fastening bolt nose shape coupling, when assembling scraper bowl side edge, can make the fastening bolt positioning and fixing; During fastening nut, can prevent the bolt transfer; In the scraper bowl use, prevent to change side edge after the wearing and tearing of fastening bolt head, thereby provide convenience for assembling, keep in repair side edge.
Advantage of the present utility model and characteristics will illustrate by the non-limitative illustration of following preferred embodiment and explain that these embodiment only provide as an example with reference to accompanying drawing.
Description of drawings
Fig. 1 is that the utility model is contained in the structural representation on the scraper bowl;
Fig. 2 is the I portion enlarged drawing of Fig. 1;
Fig. 3 is that the utility model is contained in the stereogram on the scraper bowl.
The specific embodiment
The utility model is described in further detail below in conjunction with drawings and Examples.
As Fig. 1～shown in Figure 3, the side edge 2 of present embodiment is separately fixed at end plate 12 outsides of power shovel 1, and during excavator work, side edge 2 three faces of the teeth 11 of power shovel 1 front end and both sides surround, and forms scraper bowl 1 and can shovel the section area of cutting.Be respectively equipped with wear strip 3 in the inboard of scraper bowl two end plates 12, this wear strip 3 is welded to connect with scraper bowl two end plates 12.Wear strip 3 is corresponding with the position of side edge 2, the wear strip 3 of present embodiment is provided with two rows totally 6 through holes 31, described through hole 31 and fastening bolt head 41 form fit, as polygonal hole of hexagon ring, square hole, rectangular opening, pentagon hole or other shapes etc., its effect is to make fastening bolt head 41 location, prevents that fastening bolt 4 from rotating.Fastening bolt 4 passes wear strip 3, end plate 12, side edge 2 from scraper bowl 1 two end plates 12 inboard priorities respectively, and fastening bolt head 41 is positioned in the through hole 31, by the clamp nut 5 that is positioned at side edge 2 outsides side edge 2 and end plate 11 is linked into an integrated entity.Locate and adapt to the welding position deviation of wear strip 3 and scraper bowl end plate 12 for convenience, the overall size of through hole 31 is than the big 2～3mm of fastening bolt 4 head dimensions.
Because wear strip 3 has been welded on the scraper bowl end plate 12, during assembling side edge 2, only need fastening bolt 4 is inserted wear strips 3, fastening bolt head 41 is entered in the wear strip through hole 31 with its form fit.After fastening bolt 4 passes side edge 2, just can connect side edge 2 and power shovel 1 with clamp nut 5 in side edge 2 outsides, because fastening bolt head 41 is located in wear strip through hole 31, when tightening clamp nut 5, fastening bolt 4 can not rotate.During the utility model work; because wear strip 3 protection fastening bolt heads 41 have been arranged, make power shovel 1 in mining process, although be subjected to hard objects collision, friction such as rock; fastening bolt head 41 still can not rotate, and is convenient, fast when changing side edge 2.
In addition to the implementation, the utility model can also have other embodiments, and all employings are equal to the technical scheme of replacement or equivalent transformation formation, all drop in the protection domain of the utility model requirement.
