For solving the technical problem, the utility model provides a pair of compensating beam device of hoist anchor hook hanging point conversion, include the gib head coupling mechanism that links to each other with two gib heads of hoist, with a word compensating beam that gib head coupling mechanism connects, the frame of a word compensating beam comprises a plurality of vertical risers and horizontal backup pad, be equipped with a plurality of shaft holes on the length direction of a word compensating beam, demountable installation has the mechanism of hanging in the shaft hole, the length of hanging the mechanism compares the width of a word compensating beam is slightly wide.

Preferably, the axle holes are evenly distributed on the linear balance beam.

Preferably, the hook head connecting mechanism comprises a hook head connector and a connecting piece, the upper end of the connecting piece is connected with the hook head connector, and the lower end of the connecting piece is fixed on the upper surface of the linear balance beam.

Preferably, the connecting piece is a pulling plate, the upper surface of the linear balance beam is provided with a plurality of plate-type lifting lugs which are uniformly distributed, and the lower end of the pulling plate is fixed on one pair of the plate-type lifting lugs which are symmetrical.

Preferably, the hanging mechanism is a pin.

The beneficial effects of the utility model are that:

1. the utility model discloses a setting and two gib heads of hoist link to each other gib head coupling mechanism, with a word compensating beam that gib head coupling mechanism connects is equipped with a plurality of shaft holes on the length direction of a word compensating beam, demountable installation has the suspension mechanism in the shaft hole, through gib head coupling mechanism with a word compensating beam connects, becomes single hook device with the many flukes of hoist, and the lifting rigging only needs the adaptation the specification of suspension mechanism need not to replace less gib head or increase hoist and lifting device's connecting rigging specification, simple structure, convenient to use, repeatedly usable.

2. The utility model discloses a demountable installation has the mechanism of hanging in the shaft hole, will according to the equipment of hoist and mount hang the mechanism installation in the shaft hole of suitable position to hang the rigging during hoist and mount operation in hang the mechanism both ends, slide with the check out test set through equipment gravity automatic adjustment rigging, when avoiding double lifting point hoist and mount operation of anchor hook and hoist and mount odd hoisting point equipment is difficult to the leveling to take one's place or the dead unable pivoted condition of gib head incline card, safe and reliable.

3. The utility model discloses a be equipped with a plurality of evenly distributed's board-like lug at the upper surface of a word compensating beam, through the fixed board-like lug of adjustment arm-tie, davit moment's regulation when realizing the hoist and mount operation.

Detailed Description

As shown in fig. 1-2, the balance beam device for crane anchor hook hanging point conversion comprises a hook head connecting mechanism connected with two hook heads of a crane and a linear balance beam 1 connected with the hook head connecting mechanism, wherein the hook head connecting mechanism comprises a hook head connector 2 and a connecting piece 3, the upper end of the connecting piece is connected with the hook head connector 2, the connecting piece 3 is a pulling plate, and the lower end of the connecting piece 3 is fixed on the upper surface of the linear balance beam 1. The frame of a word compensating beam 1 comprises a plurality of vertical risers 4 and horizontal backup pad 5, be equipped with a plurality of shaft holes 6 on the length direction of a word compensating beam 1, shaft hole 6 evenly distributed in on a word compensating beam 1, demountable installation has in the shaft hole 6 and hangs mechanism 7, it is the round pin axle to hang mechanism 7, the length of hanging mechanism 7 is than the width of a word compensating beam 1 is slightly wide.

The upper surface of the straight balance beam 1 is provided with a plurality of plate-type lifting lugs 8 which are uniformly distributed, and the lower ends of the pulling plates are fixed on one pair of the plate-type lifting lugs 8 which are symmetrical.

As shown in fig. 4-6, the utility model discloses a connecting piece 3 with a word compensating beam 1 is connected, be equipped with a plurality of shaft holes 6 on the length direction of a word compensating beam 1, demountable installation has suspension mechanism 7 in the shaft hole 6, changes the many flukes of hoist into single hook device, and suspension rigging 9 only needs the adaptation suspension mechanism 7's specification need not to replace less gib head or increase hoist and lifting device's connection rigging specification, simple structure, convenient to use, repeatedly usable.

As shown in fig. 5 and 6, before the hoisting operation, the hoisting mechanism 7 is installed into the shaft hole 6 at a proper position according to the hoisted equipment, the hoisting rigging 9 is hung at two ends of the hoisting mechanism 7 during the hoisting operation, the hoisting rigging 9 is automatically adjusted to slide by the gravity of the equipment so as to keep the balance of the equipment, the condition that the equipment is difficult to level and put in place during the anchor hook double-hoisting operation and the equipment with odd hoisting points is hoisted or the hook head is obliquely clamped and can not rotate is avoided, and the hoisting operation is safe and reliable.

In addition, because the upper surface of the straight balance beam 1 is provided with the plurality of uniformly distributed plate-type lifting lugs 8, the moment of the suspension arm is adjusted during the hoisting operation by adjusting the plate-type lifting lugs 8 fixed by the pulling plate.
