Abstract
The utility model discloses a fast changing device for workpiece of loading machine comprising a fast changing device frame, a fast changing pull rod, an upper pin, a fast changing cylinder and a lower pin. The upper pin is fixedly arranged on the upper part of the fast changing device frame through anti rotary plate and bolts. The fast changing pull rod is hinged at the middle part of the upper pin. The upper pin is provided with a shaft sleeve and an oil cup. The back of the fast changing pull rod is hinged with the loading machine rocker arm. The lower pin is hinged on the lower bracket of the fast changing device frame, and is hinged with the loading machine boom. The fast changing cylinder is fixed through bolts in the lower box at the lower part of the fast changing device frame. The piston rods at two ends of the fast changing cylinder are respectively hinged with the lower pin through joint pins. The utility model is an upper and lower hinge hole type structure. The fast changing pull rod, the upper hinge joint of the working part and the upper hinge joint of the fast changing device frame are hinged on one axis, while the anterior hinge joint of the boom, the lower hinge joint of the working part and the lower hinge joint of the fast changing device are hinged on another axis. The device is simple in structure, high in strength, convenient to use, small in whole machine load fluctuation, and can fast change workpiece of loading machine.
Description
Technical field the utility model belongs to the loader technical field, relates to a kind of loader workpiece fast replacing device.
The background technology loader is in use occasions such as goods yard, harbour, urban construction, because of working condition often changes, for effectively utilizing loader, realize a tractor serves several purposes, loader often need carry various workpieces, as in scraper bowl, clamping machinery, dozer, snow removing equipment, the crushing appliance etc. one or more, it is big when these workpiece are changed because of weight, remove and install difficulty, generally need are assisted with large-scale instruments such as cranes or are changed to workshop, and damage bearing pin easily, therefore need a kind of simple and reliable maneuverable substitute mode.
The summary of the invention the purpose of this utility model provides a kind of simple and reliable maneuverable loader workpiece fast replacing device, to overcome the deficiencies in the prior art.
To achieve these goals, the utility model loader workpiece fast replacing device, it comprises fast replacing device frame, quick change pull bar, upper pin, quick change oil cylinder and lower bearing pin; Said upper pin is arranged on the top of fast replacing device frame by torsional stop and bolt, and the quick change pull bar is hinged on the middle part of upper pin, and upper pin is provided with axle sleeve and lubricating cup, and the rear portion of quick change pull bar and loader rocking arm are hinged; Said lower bearing pin is hinged on the support of fast replacing device frame bottom, and hinged in loading arm; Said quick change oil cylinder is by in the lower box that is bolted to fast replacing device frame bottom, and the piston rod at quick change oil cylinder two ends is hinged by attachment pegs with lower bearing pin respectively.
For preventing that materials such as earth from entering lower box, said lower box peripheral hardware cover plate.
Said quick change pull bar middle part is provided with reinforcing rib.
Said lower box is provided with the oil cylinder limited block.
The utility model does not change the principal parameter of former equipment, as discharge height, unloading distance etc., structure letter, single intensity height, realize that with four groups of common on the domestic market hinge holes device of quick change is different, this fast replacing device is upper and lower two groups of hinge hole type structures, be that hinge is hinged on same axle on hinge on quick change pull bar, the workpiece, the fast replacing device frame, before the swing arm under hinge, the workpiece under hinge, the fast replacing device hinge hinged on another axle.It is simpler that this installs relative structure, the intensity height, and easy to use, the complete machine fluctuation of load is little, can realize the quick change of loader workpiece.
Description of drawings Fig. 1 is the utility model structural representation front view;
Fig. 2 be among Fig. 1 A-A to view.
The specific embodiment is according to Fig. 1, Fig. 2, and the utility model comprises fast replacing device frame 1, quick change pull bar 2, upper pin 5, quick change oil cylinder 10 and lower bearing pin 7; Upper pin 5 is arranged on the top of fast replacing device frame 1 by torsional stop 6 and bolt, and quick change pull bar 2 is hinged on the middle part of upper pin 5, and upper pin 5 is provided with axle sleeve 3 and lubricating cup 4, and the rear portion of quick change pull bar 2 and loader rocking arm are hinged; Lower bearing pin 7 is hinged on the support of fast replacing device frame 1 bottom, and hinged in loading arm; Quick change oil cylinder 10 is by in the lower box that is bolted to fast replacing device frame 1 bottom, and the piston rod at quick change oil cylinder 10 two ends is hinged by attachment pegs 8 with lower bearing pin 7 respectively; Lower box peripheral hardware cover plate 9; Quick change pull bar 2 middle parts are provided with reinforcing rib 11; Lower box is provided with oil cylinder limited block 12.
With reference to Fig. 1, Fig. 2, the utility model structure and operating principle be auspicious state as follows: upper pin 5 usefulness torsional stops 6 and being bolted on the fast replacing device frame 1, quick change pull bar 2 is hinged on upper pin 5 middle parts, can rotate around this axle, carry out grease lubrication by axle sleeve 3 and lubricating cup 4, the rear portion of quick change pull bar 2 and loader rocking arm are hinged.Lower bearing pin 7 and fast replacing device frame 1, swing arm are hinged, quick change oil cylinder 10 is fixed by bolts in fast replacing device frame 1 lower box, the two-piston bar is hinged by attachment pegs 8 with lower bearing pin 7 respectively, lower bearing pin 7 is finished stretching motion under the effect of oil cylinder, workpiece such as scraper bowl lower link point are hinged on lower bearing pin 7 outermost, 9 pairs of fast replacing device lower boxes of cover plate seal, and prevent that materials such as earth from entering.The concrete course of work is as follows, scraper bowl keeps flat ground, shrinking quick change oil cylinder 10 makes lower bearing pin 7 outsides be reduced to swing arm hinge hole inside fully, but the spacing swing arm that do not cause of oil cylinder self is deviate from from lower bearing pin 7, handle the loader walking near scraper bowl and make that hinge hangs on the hinge pin axle 5 on the scraper bowl, promote swing arm, scraper bowl by gravity automatically and fast replacing device frame 1 spacing, hinge is coaxial under this moment lower bearing pin 7 and the scraper bowl, operating hydraulically operated cylinder piston rod ejects, lower bearing pin 7 is overhanging, and hinge hole is hinged on the lower bearing pin 7 under the scraper bowl, realizes quick change.When changing, shrink quick change oil cylinder 10, drive in the lower bearing pin 7 and contract, hinge is deviate under the scraper bowl, falls the swing arm rearloader and retreats, and workpiece unloads.One group of parallel connection that oil cylinder turnover oil pipe line can be used in three valves picks out, and interface increases by one or two position four-way solenoid valve and cooperates control crank to realize the control of oil cylinder, handles simple and convenient.
