Set up flexible baffle 101 on the driving gib head 1, the fixed setting in flexible baffle 101 upper end is in the inboard on driving gib head 1 upper portion, the lower extreme is the free end and is close to the outermost end of driving gib head 1 lower part.

The automatic assembling and disassembling device for the hook head sling as shown in fig. 1-5 has the following automatic assembling and disassembling processes:

1) the hoisting ring is automatically installed into the crane hook head 1:

in the initial state, as shown in fig. 1, the attachment/detachment member 2 is in a horizontal state with its opening on the right side, and the suspension ring shown in fig. 4 is placed on the electromagnetic plate 201.

Control driving gib head 1 and remove the opening of dismouting piece 2 of U type and be close to rings, then continue to walk and make liftout portion 21 support the flexible baffle 101 on the driving gib head 1 that moves ahead to rotate towards the rear and open, form the entry between driving gib head 1 and the flexible baffle 101, liftout portion 21 tip this moment with space between the driving gib head 1 increases, as shown in figure 5, operation driving gib head 1 descends to make dismouting piece 2 rotate and be in the tilt state, operate driving gib head 1 forward simultaneously, so that rings detain through this space driving gib head 1.

After the travelling crane hook head 1 is hung into the hanging ring, the travelling crane hook head 1 carrying the hanging ring is controlled to move backwards, so that the end part of the jacking part 21 is gradually separated from the flexible baffle 101 of the travelling crane hook head 1, and the inlet is gradually reduced; after the flexible baffle 101 is recovered to the normal state, the crane hook head 1 carrying the hanging ring is controlled to lift upwards, so that the hanging ring is automatically installed in the crane hook head 1.

After the crane hook head 1 is lifted upwards to be separated from the dismounting part 2, the counterweight block 202 arranged on the dismounting part 2 is matched with the T-shaped buffer part 5, so that the dismounting part 2 is in a horizontal state.

2) Clamping and hoisting:

then the crane hook head 1 is controlled to hoist the hanging ring and the goods carried by the hanging ring to carry out clamping and hoisting work, the goods are hoisted to a target area, and then the goods are unloaded.

3) Automatic unhooking of rings:

after the crane hook head 1 finishes clamping and hoisting, the hoisting ring is in an empty state (namely, the hoisting ring does not carry goods).

The crane hook head 1 carrying the hanging ring is controlled to move to the mounting plate 22 of the dismounting part 2 in the horizontal state, and the hanging ring is positioned above the electromagnetic force plate 201 in the mounting plate 22.

Then control driving gib head 1 to 23 directions of arc portion remove for 21 tip of jack-up portion support the flexible baffle 101 on the driving gib head 1 that moves ahead to rotate towards the rear direction and open, the entry increase between driving gib head 1 and the flexible baffle 101, control driving gib head 1 decline this moment and make the dismouting piece 2 rotate and be in the tilt state, and operation driving gib head 1 moves backward simultaneously, so that rings follow the roll-off in driving gib head 1.

And then controlling the traveling crane hook head 1 to move backwards and separate from the detachable part 2, wherein the jacking part 21 of the detachable part 2 is separated from the flexible baffle 101, and controlling the traveling crane hook head 1 to lift upwards after the flexible baffle 101 returns to the normal state.

Meanwhile, under the action of the balancing weight 202 and the T-shaped buffer part 5, the dismounting part 2 is restored to the horizontal state, so that the automatic unhooking of the hanging ring is realized.

It will be appreciated that the movement of the hook head 1 is controlled by the vehicle.
