Abstract
A demolition apparatus and an adapter frame of the demolition apparatus are disclosed. The adapter frame may be formed with coupling seats which engage pins on a jaw set to assemble the demolition apparatus. The openings of the coupling seats face different directions for quick and simple assembly of the demolition apparatus. A rotatable locking element may be provided on the adapter frame to lock a pin on the jaw set.
Claims15
An adapter frame of a demolition apparatus, the adapter frame comprising:
- a housing provided with spaced-apart first and second coupling seats to engage with a jaw set and a mounting member for connection to an arm of a machine;
- and
- at least one locking element rotatably supported at one of the second coupling seats.
A demolition apparatus comprising
- a jaw set having a first jaw pivotally connected to a second jaw, the jaw set further comprising a pivot pin and a coupling pin provided on the first jaw;
- an adapter frame connectable to an arm of a machine, the adapter frame having a housing provided with spaced-apart first and second coupling seats to engage with the pivot pin and the coupling pin and a cylinder to pivot the second jaw relative to the first jaw;
- and
- at least one locking element rotatably supported at one of the second coupling seats for retaining the coupling pin.
An adapter frame of a demolition apparatus the adapter frame comprising:
- a housing provided with spaced-apart first and second coupling seats to engage with a jaw set and a mounting member for connection to an arm of a machine, wherein the openings of the first coupling seats and the second coupling seats face different directions.
A demolition apparatus comprising
- a jaw set having a first jaw pivotally connected to a second jaw, the jaw set further comprising a pivot pin (26 and a coupling pin provided on the first jaw);
- an adapter frame connectable to an arm of a machine, the adapter frame having a housing provided with spaced-apart first and second coupling seats to engage with the pivot pin and the coupling pin and a cylinder to pivot the second jaw relative to the first jaw;
- and
- wherein the openings of the first coupling seats and the second coupling seats face different directions.
A method of assembling the demolition apparatus, the method comprising the steps of:
- providing a jaw set having a first jaw pivotally connected to a second jaw, the jaw set further comprising a pivot pin and a coupling pin provided on the first jaw;
- connecting an adapter frame to an arm of a machine, the adapter frame having spaced-apart first and second coupling seats to engage with the pivot pin and the coupling pin and a cylinder to pivot the second jaw relative to the first jaw, wherein the openings of the first coupling seat and the second coupling seat face different directions;
- moving the adapter frame to engage the pivot pin into the first coupling seats;
- and
- engaging the coupling pin into the second coupling seats through rotation of the jaw set relative to the adapter frame.
The method of 14 wherein step of moving the adapter frame comprises a movement in the direction of extension of the cylinder.
