The specific embodiment
Fig. 1 has shown a machine 10, wheel loader for example, machine 10 also can be carry out some with special industry, for example dig up mine, build, the machine of other any kinds of operation that agricultural, transportation etc. are relevant.
In one embodiment, scraper bowl 13 can removably connect a main frame 14 that is used to change the fast replacing device 20 of Work tool, the main frame 14 of fast replacing device 20 pivots and connect two pivotable linking arms 15 that stretch out on vehicle frame 12, only shown one among Fig. 1, for example the lift arm of loader.Linking arm 15 can be set to one or more as required.Linking arm 15 can pivot by two lifting cylinders 16 and activate, and has also only shown a lifting cylinder 16 among Fig. 1.Fast replacing device 20 also can pivot with connecting rod 17 and be connected, and connecting rod 17 is connected with swing arm 18 pivots and by swing arm 18 controls, the swing of swing arm 18 is then controlled by the oil cylinder 19 that is arranged in vehicle frame 12 tops.
As shown in Figures 2 and 3, fast replacing device 20 comprises main frame 14, and main frame 14 comprises two body side frames 21,22, under(-)chassis 23 and top frame 24.Main frame 14 also can adopt other structures and shape, and is irregularly shaped as circle or other.The linkage interface 31 that has machine in main frame 14 is formed with two pairs of installing holes 32,33 respectively in linkage interface 31 relative both sides.In the linkage interface of main frame 14, have body side frame 21, reach body side frame 22 by plate 221,222 formation of two spaces by plate 211,212 formation of two spaces.Two pairs of installing holes 32,33 are respectively formed at the plate 211,212 of space and 221,222 bottom.Longitudinally be formed with the plate 411,412 of two block gaps at the middle part of main frame 14, the middle and upper part of plate 411,412 at interval is formed with a pair of installing hole 41, and in order to admit bearing pin 42, bearing pin 42 can pivot with the connecting rod 17 of machine 10 and be connected.Be fixedly connected with stiffener 213,223 respectively between the plate 211,212 and 221,222 of space.Stiffener 213,223 can be fixedly connected between the plate 211,212 and 221,222 of two block gaps by the mode of welding or other modes of prior art.
The under(-)chassis 23 of main frame 14 can be welded by the polylith metal sheet.As shown in Figures 2 and 3, under(-)chassis 23 is by roof 231, inside wall 232, the tubulose that diapire 233 and lateral wall 234 surround.As shown in Figure 3, the roof 231 of under(-)chassis 23 and inside wall 232 are formed by the single piece plate bending, and diapire 233 and lateral wall 234 are also formed by the single piece plate bending.With two single piece plate welding, formed the under(-)chassis 23 of tubulose.Under(-)chassis 23 also can be prefabricated tubular structure, perhaps respectively by the roof 231 of monolithic, and inside wall 232, diapire 233 and lateral wall 234 are welded.Tubular structure can guarantee the structure that under(-)chassis is light and firm.Near the inboard that is formed with installing hole 32,33 on the side frame 21,22, i.e. installing hole 32,33 opposed inside are limited the space 51,52 of removable bearing pin 39 respectively by the opening part at under(-)chassis 23 two ends of tubulose.Further, shown in Figure 3 as Fig. 2, on the diapire 233 of the under(-)chassis 23 of tubular structure and lateral wall 234, be formed with opening 235,236, in under(-)chassis 23, to form recess 61,62.On the diapire 233 or lateral wall 234 that opening also can only be formed on separately, opening also can be formed on roof 231, the inside wall 232.Recess 61,62 can be near the space bar 212 of body side frame 23,222 form, and promptly form recess at under(-)chassis 23 spout parts, with body side frame 21, after 22 welding, formation is near the recess 61,62 of space bar 212,222, make things convenient for instrument directly the bearing pin 39 that inserts installing hole 32,33 to be applied external force.
On connection bearing pin 39 catch 38 can be installed, catch 38 can play the backstop effect when bearing pin 39 is installed, and also can apply external force by catch 38 and make things convenient for removing of bearing pin 39 when dismounting bearing pin 39.In the machine linkage interface 31 of main frame 14, also can form other installing holes, in order to admit the connection bearing pin that connects Work tool 13.
The fast replacing device of machine of the present utility model is applicable to various Work machines, as wheel loader etc. or other be used to build, the machinery of engineering or agricultural.
When the main frame 14 of fast replacing device 20 is installed, with the installing hole of linking arm 15 ends and the body side frame 21 of main frame 14, installing hole 32,33 alignment on 22 are from body side frame 21,22 outside applied thrust, bearing pin 39 is inserted from the outside of side frame 21,22 in the installing hole of alignment, simultaneously can with the installing hole of connecting rod 17 ends be formed on middle ware dividing plate 411, installing hole 41 alignment on 412 are inserted bearing pin 42 in the installing hole of alignment.Thereby main frame 14 is connected with machine 10 pivots.The opposite side relative that the scraper bowl 13 of removable Work tool, for example loader is removably mounted on main frame 14 with linking arm 17.
When on linking arm 15, dismantling the main frame 14 of fast replacing device 20, the recess 61 that can from under(-)chassis 23, form by instrument, in 62 bearing pin 39 is applied external force, as by hammer from recess 61, outwards knock bearing pin 39 in 62, simultaneously, can be pulled outwardly the axle 39 of pulling pin by stop tab 38 from the outside of side frame 21,22.Owing to all can apply external force to bearing pin 39 in the medial and lateral of installing hole 32,33, can easily bearing pin 39 be shifted out from installing hole 32,33 thus, main frame 14 conveniently separates with linking arm 15.
Those skilled in the art obviously understand, can make various modifications and variations and can not break away from the scope of the present disclosure disclosed fast replacing device.In view of the practice of this manual and embodiment disclosed herein, other embodiment of the present utility model is conspicuous to those skilled in the art.It only is exemplary that this manual and example should be regarded as, and true scope of the present utility model is defined by the following claims.
