Under the joint action of the first lifting control mechanism 2 and the second lifting control mechanism 3, the upper frame 1 of the lifting device can be conveniently controlled in all directions and stabilized and prevented from shaking.

[0044] Specifically, in an embodiment of this utility model, the hoisting drum 4 is arranged in a direction parallel to the left-right travel direction of the crane trolley.

[0045] Specifically, in an embodiment of this utility model, the lifting drum 4 includes: a lifting drum body; and a lifting drive motor connected to the lifting drum body.

[0046] Specifically, in an embodiment of this utility model, the first auxiliary drum 5 or the second auxiliary drum 6 includes: an auxiliary drum body; and a variable frequency motor connected to the auxiliary drum body.

[0047] Specifically, in the embodiments of this utility model, the first lifting control mechanism 2 or the second lifting control mechanism 3 further includes a locking component 15 connected to the first auxiliary drum 5 and the second auxiliary drum 6.

[0048] Specifically, in an embodiment of this utility model, the locking component 15 includes: a brake disc disposed on the auxiliary drum body and rotating with the auxiliary drum body; and a locking caliper connected to the brake disc.

[0049] like Figure 2 As shown in the embodiment of this utility model, the locking component 15 is used to lock the rotational movement of the first auxiliary drum 5 and the second auxiliary drum 6. The main structure of the locking component 15 consists of the brake disc and the locking caliper. The brake disc is installed on the side wall of the auxiliary drum body and rotates together with the auxiliary drum body. The locking caliper engages with the brake disc. When it is necessary to restrict the rotational movement of the first auxiliary drum 5 or the second auxiliary drum 6, the locking caliper clamps the brake disc, thereby achieving the technical effect of locking the drum and restricting its rotation.

[0050] Specifically, in the embodiments of this utility model, the first guide pulley 7 and the second guide pulley 8 are arranged in parallel; the third guide pulley 9 and the fourth guide pulley 10 are arranged in parallel; and the fifth guide pulley 11 and the sixth guide pulley 12 are arranged in parallel.

[0052] Specifically, in an embodiment of this utility model, the supporting column is movably connected to the guide pulley.

[0054] When the lifting frame 1 needs to perform lifting or lowering movements, the lifting drums 4 in the first lifting control mechanism 2 and the second lifting control mechanism 3 rotate synchronously to realize the lifting and lowering of the lifting frame 1; at the same time, the locking component 15 locks the first auxiliary drum 5 and the second auxiliary drum 6 in the first lifting control mechanism 2 and the second lifting control mechanism 3, so that the first lifting wire rope 13 and the second lifting wire rope 14 are in a triangular shape in both the trolley and the carriage travel direction, which has an anti-sway function;

[0055] When the lifting device 1 needs to perform a clockwise rotation, the first auxiliary drum 5 in the first lifting control mechanism 2 winds up the rope and the second auxiliary drum 6 is locked, and the first auxiliary drum 5 in the second lifting control mechanism 3 winds up the rope and the second auxiliary drum 6 is locked, thus realizing the clockwise rotation of the lifting device 1.

[0058] When the lifting device 1 needs to perform a backward tilting action, the first auxiliary drum 5 and the second auxiliary drum 6 in the first lifting control mechanism 2 wind up the rope, and the first auxiliary drum 5 and the second auxiliary drum 6 in the second lifting control mechanism 3 unwind the rope, so that the lifting device 1 can perform a backward tilting action.

[0059] When the lifting device 1 needs to perform a left tilting action, the first auxiliary drum 5 in the first lifting control mechanism 2 releases the rope and the second auxiliary drum 6 retracts the rope, and the first auxiliary drum 5 in the second lifting control mechanism 3 retracts the rope and the second auxiliary drum 6 releases the rope, thus realizing the left tilting action of the lifting device 1.

[0060] When the lifting device 1 needs to tilt to the right, the first auxiliary drum 5 in the first lifting control mechanism 2 winds up the rope and the second auxiliary drum 6 unwinds the rope, while the first auxiliary drum 5 in the second lifting control mechanism 3 unwinds the rope and the second auxiliary drum 6 winds up the rope, thus achieving the left tilting action of the lifting device 1.

[0061] As described above, the container gantry crane provided by this utility model, which offers convenient all-around control and anti-sway features for the spreader, aims to solve the problem that traditional container gantry cranes can only rotate the spreader within a plane by ±5° during operation, lacking convenient all-around control and anti-sway features, and thus cannot quickly align containers during loading and unloading, resulting in low operating efficiency.

The first lifting wire rope 13 passes around the first guide pulley 7, the third guide pulley 9, and the fifth guide pulley 11, connecting the trolley frame to the upper frame of the lifting device 1. Then, using the lifting drum 4 and the first auxiliary drum 5, the movement of one side of the upper frame of the lifting device 1 can be controlled. The second lifting wire rope 14 passes around the second guide pulley 8, the fourth guide pulley 10, and the sixth guide pulley 12, connecting the trolley frame to the upper frame of the lifting device 1. Then, using the lifting drum 4 and the second auxiliary drum 6, the movement of the other side of the upper frame of the lifting device 1 can be controlled. The first lifting control mechanism 2 and the second lifting control mechanism 3 are symmetrically arranged at the left and right ends of the upper frame of the lifting device 1. Their combined action enables convenient all-around control of the lifting device. Secondly, regarding the winding method of the wire rope, the first lifting wire rope 13... The first lifting wire rope 13 winds downwards around the first guide pulley 7, upwards around the third guide pulley 9, and downwards around the fifth guide pulley 11, with its two ends connected to the lifting drum 4 and the first auxiliary drum 5, respectively. The second lifting wire rope 14 winds downwards around the second guide pulley 8, upwards around the fourth guide pulley 10, and downwards around the sixth guide pulley 12, with its two ends connected to the lifting drum 4 and the second auxiliary drum 6, respectively. Through the above winding method, the projections of the first lifting wire rope 13 and the second lifting wire rope 14 in both the trolley travel direction and the trolley travel direction are triangular, providing an anti-sway function. Therefore, the technical solution provided by this utility model, compared with the prior art, has a convenient all-round adjustment and anti-sway function for the lifting device, enabling rapid container alignment during loading and unloading, and improving operational efficiency.
