Referring to fig. 1, a pendant device for an electric hoist includes a mounting portion 1, a retracting lever 4, a rotating hook 6, and a rotating driving member 7.

In the present utility model, the direction in which the electric hoist transports goods along the rail is defined as the front-back direction (the direction of the horizontal portion 2 with respect to the vertical portion 3 is defined as the front, and the direction of the vertical portion 3 with respect to the horizontal portion 2 is defined as the rear); the other two directions in the horizontal plane are defined as the left-right direction.

Referring to fig. 1, the mounting portion 1 includes a horizontal portion 2 and a vertical portion 3. In one embodiment, the horizontal portion 2 is fixedly connected to the lower end of the lifting hook 8 of the electric hoist in a welding manner, the vertical portion 3 is integrally and fixedly connected to the horizontal portion 2 and extends downwards, and the vertical portion 3 is located at the rear end of the horizontal portion 2. The mounting part 1 is used for providing a mounting position.

Referring to fig. 1, the rotating hook 6 is rotatably connected to the vertical portion 3, and the rotation axis thereof is along the left-right direction. The rotation driving part 7 is arranged on the mounting part 1 and is used for driving the rotation hook 6 to rotate. The arrangement is that a worker can control the position of the rotating hook 6 through the electric hoist to align the hanging hole at the upper end of the goods, then control the rotation of the rotating hook 6 through the rotation driving part 7 to enable the rotating hook 6 to be in a horizontal state, so that the rotating hook 6 can easily enter the hanging hole, and then control the rotating hook 6 to rotate upwards, so that the rotating hook 6 is difficult to be separated from the hanging hole; after the goods reach the transfer destination, the rotation of the rotating hook 6 can be controlled to be separated from the hanging hole, and unloading is completed. Thereby replacing the manual hanging and taking down of the hook by workers.

Referring to fig. 1 and 2, in one embodiment, the front and rear ends of the rotating hook 6 extend beyond the vertical portion 3, the rotation driving component 7 includes a hydraulic cylinder, the hydraulic cylinder is located at the rear end of the vertical portion 3, the cylinder body of the hydraulic cylinder is hinged to the vertical portion 3, the rotating shaft of the hydraulic cylinder is along the left-right direction, the tail end of the telescopic rod is hinged to the rear end of the rotating hook 6, and the rotating shaft of the telescopic rod is also along the left-right direction. The hydraulic cylinder can bear larger load, so that the hydraulic cylinder can be suitable for carrying cargoes with larger weight; the hydraulic cylinder has better self-locking performance, is more stable in the transportation process of goods, and is not easy to cause accidents.

Referring to fig. 1, in one embodiment, the front end of the rotating hook 6 can be rotated upward to contact the horizontal portion 2. By means of the arrangement, after the rotating hook 6 enters the hanging hole, the front end of the rotating hook 6 can rotate upwards to be in contact with the lower end of the horizontal portion 2, and the rotating hook 6 is prevented from falling out of the hanging hole due to the fact that the rotating hook swings back and forth in the transferring process.

Referring to fig. 1, in one embodiment, the front end of the rotating hook 6 is pointed. This is arranged so that the rotating hook 6 more easily protrudes into the hanging hole.

Referring to fig. 1, the upper end of the shrinking rod 4 is hinged to the casing 9 of the electric hoist, the lower end is hinged to the mounting portion 1, and the rotating shafts at the upper end and the lower end of the shrinking rod 4 are all along the left-right direction. In one embodiment, a connecting block 5 is fixedly extended from each of the housing 9 and the mounting portion 1 to allow the upper and lower ends of the retraction lever 4 to be hinged. The shrinkage rod 4 is used for limiting the left and right shaking of the installation part 1, so that the phenomenon that the rotation hook 6 is interfered with the alignment of the cargo hanging hole due to the left and right shaking generated in the descending process of the lifting hook 8 is avoided. When the mounting part 1 swings back and forth due to inertia during the traveling of the electric hoist, the contraction rod 4 swings accordingly, so that the electric hoist is prevented from being broken as much as possible.

In one embodiment, the material of the telescopic rod is aluminum alloy, because the aluminum alloy has higher hardness and lighter weight, the higher hardness improves the applicable working strength, and the lighter weight reduces the load applied to the electric hoist in the working process.

Referring to fig. 1, in one embodiment, preferably, two telescopic rods are respectively located at the left and right sides of the mounting portion 1, so that the overall structure is more stable.

Referring to fig. 3, in one embodiment, the cargo rack further includes a cargo rack 10, where the cargo rack 10 is placed on the ground, and the periphery of the cargo rack is fixed by anchor bolts or rivets, so as to place the cargo to be transported. Further, the pallet 10 is provided with reference lines 11 along the direction of the travelling path of the electric hoist, and the reference lines are located at the left side and the right side of the goods, so that the hanging holes on the goods are aligned, and the rotating hooks 6 are aligned and the goods are transported. Preferably, the reference line 11 may be two red or yellow waterproof tapes, so that the waterproof tapes are more striking, and are not easy to break, and when the next batch of goods with different sizes needs to be transported, the waterproof tapes can be conveniently torn off and re-attached according to the size of the next batch of goods to be used as the reference line 11.

The use of the utility model is briefly described below:

s1, placing goods to be transported on a goods placing plate 10, wherein the goods are positioned between two reference lines 11, and the hole axis directions of the hanging holes are aligned along the front-back direction;

s2, controlling the installation part 1 to descend through the electric hoist to align with the hanging hole on the goods, wherein the initial state of the rotary hook 6 is a horizontal state;

s3, controlling the rotating hook 6 to move forwards through the electric hoist, enabling the rotating hook 6 to enter the hanging hole, and enabling the hanging hole to stop after contacting the vertical part 3;

s4, driving the front end of the rotary hook 6 to rotate upwards through the rotary driving part 7 and contact the lower end of the horizontal part 2, and then lifting and transferring the goods by the electric hoist;

s5, after the goods reach the destination, the rotary driving part 7 controls the front end of the rotary hook 6 to rotate downwards and return to a horizontal state;

s6, the electric hoist controls the rotary hook 6 to move backwards, so that the rotary hook 6 is separated from the hanging hole;

s7, the electric hoist controls the mounting part 1 to move to the next goods to be transported, and the steps are repeated.
