The device comprises a traction sheave block 100, a ship unloader 200, a wharf 300, a transport ship 400, a three-door pulley 101, a single-door pulley 102, a steel wire rope 103 and a power device 104.

Detailed Description

The present invention will be further explained with reference to the following embodiments and accompanying drawings.

In the embodiments, as shown in FIGS. 1 to 5: a coupled traction sheave block comprises traction sheave blocks 100 respectively arranged on land side and sea side, wherein the land side traction sheave block 100 drives an unloader 200 to a wharf 300 direction, and the sea side traction sheave block 100 drives the unloader 200 to a carrier 400 direction. In the embodiment, the traction sheave blocks 100 on the land side and the sea side are arranged to apply force in two directions simultaneously, the ship unloader 200 can move reliably by controlling the difference value of the traction force, and the control of starting and braking is stable, so that the safety of operation is ensured.

In the embodiment, as shown in fig. 2 and 3: the traction sheave block 100 comprises three-door pulleys 101, a plurality of single-door pulleys 102, a steel wire rope 103 and a power device 104 which are arranged in pairs, wherein one three-door pulley 101 is installed on a portal frame of the ship unloader 200, and the other three-door pulley is anchored on a wharf 300 or a transport ship 400; the steel wire 103 sequentially bypasses the two three-door pulleys 101 and the plurality of single-door pulleys 102 to the power device 104. In the structure of the embodiment, the combination of the three-door pulley 101 and the single-door pulley 102 can reduce the required traction force, and can facilitate the on-site arrangement, especially the arrangement of the traction sheave block on the transport ship 400.

In the example, as shown in fig. 2: the power device 104 is a winch or a loading vehicle. Generally, the power plant 104 on the land side is a loading vehicle, which is flexible and highly controllable, while the power plant 104 on the sea side is a winch suitable for the narrow space of the transport ship.

In the embodiment, as shown in fig. 4 and 5: the traction sheave blocks 100 are all installed on one side of the gantry of the ship unloader 200 close to the shore. The traction sheave blocks 100 are all arranged on the landing leg of the ship unloader 200 portal frame on the side close to the shore, so that the traction sheave blocks 100 on the sea side can be ensured to have enough migration space, and the overturning caused by uneven acting force can be avoided.

In the example, as shown in fig. 2: each ship unloader 200 is provided with four sets of the traction sheave blocks 100, two sets being land sides and two sets being sea sides; the traction sheave blocks 100 on the land side and the sea side are respectively arranged in pairwise symmetry; all of the traction sheave blocks 100 are in synchronous traction. The above measures are all used for ensuring the stability of the traction force and ensuring the stability and reliability of the rolling movement of the ship unloader 200.
