Embodiment
nullA kind of retractor device of excavator brachium，Such as Fig. 1、Shown in Fig. 2，Including scraper bowl 1、Dipper 2、Swing arm 3、Dipper hydraulic cylinder 8，The end of the hinged dipper of scraper bowl 12，Scraper bowl 1 is hinged with one end of connecting rod 6，The other end of connecting rod 6 is hinged with rocking bar 7，The hinged dipper of rocking bar 72，The middle part of dipper 2 is hinged with one end of bucket hydraulic cylinder 4，The other end of bucket hydraulic cylinder 4 is hinged with rocking bar 7 with connecting rod 6，Also include extensible member 5，One end of extensible member 5 is provided with telescopic shaft 1，The other end of extensible member 5 is provided with telescopic shaft 3 11，Dipper 2 is provided with the cavity for accommodating extensible member 5，The both sides of cavity are arranged in order and are arranged in pairs the draw-in groove 12 for accommodating telescopic shaft 3 11 respectively，The end of cavity is provided with the retention grooves 13 for accommodating telescopic shaft 1，The end of the end articulated telescopic part 5 of swing arm 3，The middle part of the hinged swing arm in one end 3 of dipper hydraulic cylinder 8，The other end of dipper hydraulic cylinder 8 middle part by telescopic shaft articulated telescopic part 5.Extensible member 5 includes interior fitting 51 and package assembly 52, and package assembly 52 is provided with the inside groove for accommodating interior fitting 51, and interior fitting 51 can in the inside groove of package assembly 52 inwardly or move out.Swing arm 3 is hinged on interior fitting 51 or package assembly 52, and dipper hydraulic cylinder 8 is hinged on interior fitting 51 or package assembly 52.
The retractor device of this kind of excavator brachium, traditional excavator is made without the biggest change, only need simple lever principle and change some of which retractor device, achieve that and excavator brachium is stretched, only the arm of excavator simply need to be changed and can be carried out freely stretching of inside.
When brachium at excavator needs to elongate or shorten, so that it may realized by the length of regulation extensible member 5, make the brachium of excavator scale freely.As shown in Figure 3, Figure 4, Fig. 3 is the connection diagram of extensible member 5 in embodiment, the telescopic shaft 1 on top be attached fixing；The connected mode of this device and run trace thereof, only need to simply be connected, shunk by cylinder, so that it may reach shortening and the elongation of excavator brachium.
Telescopic shaft 1, telescopic shaft 2 10, telescopic shaft 3 11 use bi-directional expansion axle.Telescopic shaft 1, telescopic shaft 3 11 are vertically arranged with regulation hydraulic cylinder respectively.Telescopic shaft 1, telescopic shaft 2 10, the structure of telescopic shaft 3 11 can use identical structure, telescopic shaft 1, telescopic shaft 2 10, telescopic shaft 3 11 can use structure shown in Fig. 5 or Fig. 6.Fig. 5 and Fig. 6 is the two schemes of this extendable lever design, can be by cylinder principle or utilize spring-compressed principle to realize freely stretching of this connection lever.And the lever shaft that telescopic shaft 3 11 constantly moves for forearm, therefore there is a prominent part, match with being connected lever draw-in groove 12, make the brachium of excavator be difficult to slide fastener when carrying out flexible.When excavator needs increase the length of arm or shorten, first retraction telescopic shaft 3 11 so that it is ledge leaves draw-in groove 12, makes it move up and down by the connection lever at telescopic shaft 2 10, behind suitable position, telescopic shaft 3 11 matches with the groove of forearm in elongation.Achieve that the flexible of excavator brachium.
As shown in Figure 7, Figure 8 and Figure 9, Fig. 7 be the retractor device of excavator brachium flexible before structural representation；The package assembly 52 of extensible member 5 is driven to move down by retracting of dipper hydraulic cylinder 8, it is achieved the shortening regulation of excavator brachium, such as Fig. 9.The regulation that extends of excavator brachium is realized by the elongation of dipper hydraulic cylinder 8.
Compared with traditional excavator, the excavator of this Novel stretchable, the construction environment of significantly more efficient some complexity of reply can greatly improve the efficiency of work.For being compared to the current existing excavator extensively used, this device practicality is higher, and its operation principle is also convenient for simply.
The advantage of the retractor device of embodiment excavator brachium is
One, simple in construction, all brings great convenience to manufacturer and actually used person, and reequips also the most easily, thus greatly reduce some extra expenses such as some cost trainings.
Two, the design of hommization, the running transform fuselage that this design is carried out because of brachium in operating process on the spot not for actual operator, or directly again exchange the worries that the longer excavator of arm is loaded down with trivial details for.
Three, the brachium easy disassembly combination of excavator, can assemble freely according to the requirement of client.
