Description
Technical field
The utility model relates to a kind of counter weight of excavator self-disassembly and assembly device, belongs to excavator mounting technology field.
Background technology
At present, with regard to domestic excavator, along with continuing to increase of excavator tonnage, weight mass, just need to split excavator during the transition transportation when the excavator tonnage surpasses 40 ton hours also in continuous increase.And the first-selected parts of counterweight when to be excavator split when excavator splits transportation generally speaking, all must have the cooperation of the hanging devices such as crane just can finish dismounting to counterweight, depend merely on excavator self and can't finish dismounting.And the field construction site environment is complicated, and the place is uneven, and inconvenience is arranged when needing other equipment to cooperate more, thereby has brought many difficulties for the transition transportation of excavator.
Summary of the invention
For the problem that above-mentioned prior art exists, the utility model provides a kind of counter weight of excavator self-disassembly and assembly device, in order to finish quickly dismounting and installation to counterweight.
To achieve these goals, the technical solution adopted in the utility model is: a kind of counter weight of excavator self-disassembly and assembly device, comprise left connecting rod, the dismounting oil cylinder, right connecting rod, the counterweight holder, contiguous block, fixed axis and master cock, one end of left connecting rod and right connecting rod is assemblied on the counterweight holder, the cylinder body end of dismounting oil cylinder is assemblied on the counterweight holder, the cylinder rod end is assemblied on left connecting rod and the right connecting rod and the dismounting oil cylinder links to each other with external master cock by fluid pressure line, counterweight links to each other with contiguous block, contiguous block links to each other with fixed axis, and fixed axis is assemblied on left connecting rod and the right connecting rod.
Preferably, described left connecting rod and right connecting rod are assemblied in an end on the counterweight holder by the second bearing pin, the 3rd bolt, the 3rd baffle plate.
Preferably, the cylinder body end of described dismounting oil cylinder is assemblied on the counterweight holder by the 3rd bearing pin and steady pin.
Preferably, the cylinder rod end of described dismounting oil cylinder passes through the first bearing pin, the first baffle plate, the first bolts assemblies on left connecting rod and right connecting rod.
Preferably, described counterweight links to each other with contiguous block by pin, cottor pin, second baffle.
Preferably, described contiguous block links to each other with fixed axis with adjusting nut by the second bolt.
The beneficial effects of the utility model are: by external dismounting oil cylinder master cock, thereby hydraulic-driven dismounting oil cylinder is realized the lifting of counterweight by the motion of the flexible drive linkage of cylinder bar, after counterweight is down to assigned address, remove cottor pin, baffle plate, sell out the dismounting of paired counterweight, otherwise can finish the installation to counterweight, this counterweight self-disassembly and assembly device has the characteristics such as simple in structure, easy to operate.
Description of drawings
