Abstract
The invention discloses a simple quick-change device for a working device of a hydraulic excavator, which is characterized in that when a working device accessory is assembled, the heavy working device accessory is not required to be manually handled and adjusted, the arm-shaped opening of the simple quick-change device is clamped on the pin roll of the working device accessory to adjust the relative positions of the simple quick-change device and the working device accessory to finally enable the axes of the quick-change device and one pin roll hole of the working device accessory to be on the same line, the pin shaft is inserted to realize installation, the pin roll is only required to be disassembled during disassembling and the disassembling can be realized by slightly turning the quick-change device. The assembling and the disassembling of the working device accessory can be realized through one pin roll. The simple quick-change device has the advantages that the structure is simple, the cost is low, the quick and easy replacement of the working device accessory can be realized by using a simple mechanism, the operating time is greatly shortened, the working efficiency is improved and the labor intensity is reduced.
Description
Technical field
The present invention relates to a kind of simple and easy fast replacing device of hydraulic digger operating device, when user's desire is used other equipment annexes,, reach light quick-replaceable purpose through this easy device.
Background technology
At present; The equipment annex exploitation of domestic hydraulic crawler excavator is more and more diversified; Great variety of goods; Hydraulic crawler excavator is many not to be equipped with equipment annex fast replacing device, and this causes the user when the switch operating device fitting, must dismantle former equipment equipment annex through manpower, and the equipment annex of the desire use that changes the outfit.Because the fit clearance between equipment annex and dipper and the connecting rod is less; And the weight of equipment annex own is bigger, makes more changing jobs of equipment annex exist labour intensity big, and work difficulty is high; Characteristics such as it is long to expend time in greatly reduce production efficiency.
Summary of the invention
The object of the present invention is to provide a kind of simple mechanism that can easily change the equipment annex fast.Adopt the simple and easy fast replacing device of equipment annex of technique scheme; The excavator driver is through the operation to equipment annex fast replacing device; Be stuck on the annex bearing pin through opening circular arc simple and easy fast replacing device; Regulate the rocking bar position, a bearing pin of pulling down is before inserted the installation that pin shaft hole just can easily be realized the equipment annex.The present invention carries out the position adjustment by the arcuate structure of simple and easy fast replacing device to annex; And finally realize Fast Installation; Have mechanism efficiency height, dependable performance, simple in structure, easily manufactured, cost, the simple and easy fast replacing device of a kind of hydraulic digger operating device of characteristics such as cheap.
Technical solution of the present invention is such: a kind of simple and easy fast replacing device of hydraulic digger operating device; Comprise pedestal, bearing pin; The circular arc open card that it is characterized in that fast replacing device is on first bearing pin of equipment annex; Another hole on equipment annex and the fast replacing device is installed in the axle center of second bearing pin on same axis, inserts second bearing pin, and equipment annex and fast replacing device link together; The equipment annex is hinged through fast replacing device, connecting rod, rocking bar, between rocking bar and the dipper oil cylinder is housed.Pedestal is equipped with the 3rd bearing pin.Adorn first bearing pin, second bearing pin on the working body.
Advantage of the present invention is: be stuck on the equipment annex bearing pin through the opening circular arc with fast replacing device; Regulate the rocking bar position; By its arcuate structure annex is carried out the position adjustment; Realize easily changing fast the equipment annex, efficient height, dependable performance, simple in structure, easily manufactured, cost is low.
Description of drawings
It is such that structure of the present invention constitutes:
Fig. 1 is that overall structure of the present invention is installed the main sketch map of looking of assembling;
Fig. 2 is that the structure master of fast replacing device of the present invention looks sketch map.
Fig. 3 is an equipment structure schematic top plan view of the present invention.
Fig. 4 is an equipment structural front view of the present invention.
Fig. 5 is the left view of equipment structure of the present invention by Fig. 3.
Fig. 6 is the sketch map of assembling fast replacing device of the present invention.
Among Fig. 1～Fig. 6, equipment annex (1), fast replacing device (2), connecting rod (3), rocking bar (4), oil cylinder (5), dipper (6), pedestal (7), the 3rd bearing pin (8), working body (9), first bearing pin (10), second bearing pin (11).
The specific embodiment
Most preferred embodiment of the present invention is such: with reference to accompanying drawing, referring to Fig. 1, on dipper 6, make the hinged oil cylinder of the fit of device 5, rocking bar 4 and connecting rod 3 according to the classical inverse shovelman, be connected with fast replacing device 2 between dipper 6 and the equipment annex 1.
Referring to Fig. 2～Fig. 3, fast replacing device 2 comprises: pedestal 7 has two with bearing pin 8.
Referring to Fig. 4 and Fig. 5, equipment annex 1 comprises: working body 9, first bearing pin 10, second bearing pin 11.In assembling process, first bearing pin 10 at first assembles or is welded to shown position, and 11 of second bearing pins are when simple and easy fast replacing device 2 is adjusted the position with equipment annex 1, with the two connection.
Be simple and easy fast replacing device 2 of the present invention and equipment connection status referring to Fig. 6; When wanting erection work device fitting 1; Equipment annex 1 at first assembles or welds first bearing pin, 10 positions as shown in Figure 4, need not manpower and removes to move the heavy equipment annex 1 of adjustment, and the operator is as long as excavating on first bearing pin 10 of circular arc open card at equipment annex 1 of hands-operation with simple and easy fast replacing device 2; Adjustment also makes the axle center in another hole on equipment annex 1 and the fast replacing device 2 on same axis; Then second bearing pin 11 is inserted, equipment annex 1 and fast replacing device 2 are linked together, just accomplished the erection work of equipment annex 1.When dismantlement work device fitting 1, only need pound out second bearing pin 11, rotate fast replacing device 2 then a little, just can realize the dismounting of equipment annex 1.
The present invention is simple in structure, and is with low cost, utilizes simple mechanism to realize easily changing fast of equipment annex, shortened the operating time greatly, improved operating efficiency, alleviated labour intensity.
