Abstract
The utility model discloses a simple quick change device for a working device of a hydraulic excavator. The simple quick change device is characterized in that: when a working device accessory is assembled, the heavy working device accessory is not required to be moved and adjusted by manpower; an arc-shaped opening of the simple quick change device is clamped on a pin shaft of the working device accessory to adjust the relative positions of the working device accessory and the simple quick change device, so that finally, the quick change device and the axis of the other shaft hole of the working device accessory are on the same straight line; the working device accessory is installed by inserting the pin shaft; when the working device accessory is disassembled, only the pin shaft is detached, and the quick change device is slightly rotated. Assembly and disassembly of the working device accessory can be realized through one pin shaft. The simple quick change device has a simple structure and low cost; and the working device accessory can be quickly and easily replaced by using a simple mechanism, so that the operating time is greatly shortened, the work efficiency is improved and the labor intensity is lightened.
Description
Technical field
The utility model 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, through this easy device, reaches light quick-replaceable purpose.
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 purpose of the utility model 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 the simple and easy fast replacing device of a kind of hydraulic digger operating device of mechanism efficiency height, dependable performance, characteristics such as simple in structure, easily manufactured, with low cost.
The technical solution of the utility model 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.
The utility model has the advantages that: be stuck on the equipment annex bearing pin through 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 the structure of the utility model constitutes:
Fig. 1 is that the overall structure of the utility model is installed the main sketch map of looking of assembling;
Fig. 2 is that the structure master of the fast replacing device of the utility model looks sketch map.
Fig. 3 is the equipment structure schematic top plan view of the utility model.
Fig. 4 is the equipment structural front view of the utility model.
Fig. 5 is the left view of the equipment structure of the utility model by Fig. 3.
Fig. 6 is the sketch map of the assembling fast replacing device of the utility model.
Among Fig. 1～Fig. 6, equipment annex (1), fast replacing device (2), connecting rod (3), rocking bar (4), bucket arm 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
The most preferred embodiment of the utility model is such: with reference to accompanying drawing, referring to Fig. 1, on dipper 6, make the hinged bucket arm 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.
Referring to Fig. 6 is simple and easy fast replacing device 2 of the utility model and equipment connection status; 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 remove to move the heavy equipment annex 1 of adjustment; The operator is being 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, adjusts and make the axle center in another hole on equipment annex 1 and the fast replacing device 2 on same axis, then second bearing pin 11 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 utility model 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.
