The winch 200 maintains tension on the wire 300 through a breaker or the like installed therein when the wire 300 is wound or unwound as much as the wire 300 is set.

The wire 300 is connected to the block B and the winch 200. For example, the wire 300 connects the block B and the winch 200 in a crossover fashion. The wire 300 may be provided having various thicknesses. For example, the thickness of the wire 300 corresponding to the weight, the size, and the tension applied to the wire 300 among the plurality of wires 300 can be selected and used.

Fig. 4 is a schematic view of a guide member in a block transport system in Fig. 3; 3 to 5, the guide member 400 is detachably provided to the block B. A plurality of guide members 400 may be provided. The guide member 400 may be mounted on the block B and fixedly coupled to the wire 300. As an example, the guide member 400 may be welded when engaged with the block B. For example, the guide member 400 may be provided in a semicircular annular shape. But may be provided in other shapes and shapes.

The guide member 400 may be installed below the side surface of the block B. Guide members 400 may be provided on both sides when installed on the side surface of the block B, respectively. Alternatively, the guide member 400 may be installed on the lower surface of the block B. When the guide member 400 is provided on the lower surface of the block B, it may be installed on both sides. Alternatively, it can be installed at four corner corners.

The measurement member 500 measures the external environment. The measurement member 500 can measure the environment around the block B during its movement. For example, external environmental measurements can measure wind intensity, wind direction, current strength, or current direction. The surrounding environment measured by the measuring member 500 may be transmitted to the control unit 600 described later. The measurement member 500 includes a first measurement unit 510 and a second measurement unit 520.

The first measuring unit 510 may be installed in the crane 100. The first measurement unit 510 may be installed at the upper end of the support unit 120. For example, the first measuring unit 510 can measure wind intensity or wind direction. The external environment data measured by the first measuring unit 510 may be transmitted to the control unit 600. [

The second metering unit 520 may be installed adjacent to the ocean current. The second measuring unit 520 can measure the intensity or direction of the current. The external environment data measured by the second measuring unit 520 may be transmitted to the control unit 600. [

The control unit 600 controls the movement of the block B by adjusting the tension of the wire 300 connected to the block B based on the measurement result of the measuring member 500. [ Here, the moving state of block B may be the moving direction of block B. Alternatively, the moving state of the block B may be the moving speed of the block B. As an example, the control unit 600 may control the winch 200. The control unit 600 can control the plurality of winches 200. For example, as shown in FIG. 6 or 7, when the moving direction of the block B is shifted to one side, the winch 200 connected to the block B is controlled. More specifically, the winch 200 is wound around the wire 300 to provide a force to the wire 300 to control the movement of the block B in one direction.

The control unit 600 can control the crane 100. [ The control unit 600 can control the moving direction and the moving speed of the block B by the crane 100 based on the measurement result of the measuring member 500. [

The control unit is separately connected to the wire 300 connecting the winch 200 and the block B so as to control the tension of the wire 300 and the moving direction of the block B So that the moving state of the block B can be controlled.

Hereinafter, a method of moving the block B will be described.

Figs. 6 to 8 are diagrams schematically showing control through wires when a block is moved. Fig. 6 to 8, the block moving method includes a first stage and a second stage. Step 1 is a step of connecting the block B with the winch 200 in which the wire 300 is wound.

Specifically, when the block B is moved, the block B is transported to the vicinity of the crane 100 from the outside. After moving the block B, the guide member 400 is coupled to the block B. The guide member 400 is coupled to the block B by welding or the like. After the guide member 400 is coupled, the block B is connected to the crane 100. The connection between the block B and the crane 100 is connected through the connection part 110. [ Block B is connected to winch 200. The wire (300) connects the block (B) and the winch (200) in a crossover manner.

Step 2 is a step of moving the block B to the crane 100, measuring the external environment while moving to the predetermined position, and adjusting the tension of the wire 300 according to the result.

Concretely, the block B is connected to the crane 100 and the winch 200, and then the block B is moved to a predetermined position. The crane 100 moves the block B up and down and rotates to move the block B. The measurement member 500 measures the external environment of the block B while the block B is moving. The ambient environment measured by the metrology member 500 may be wind direction, wind direction, direction of current strength of the current. The movement of the block B is controlled by adjusting the tension of the wire 300 connecting the block B and the winch 200 when the block B is moved based on the measurement result of the measuring member 500 . For example, the moving state of the block B may be the moving direction or the moving speed of the block B. For example, as shown in FIGS. 6 and 7, when the block B is shifted in one direction from the moving direction, a force is applied to the wire 300 connected in the direction opposite to the moving direction to prevent the block B from being biased in one direction do. As another example, when the block B is severely shaken to the left and right, the winch 200 can be adjusted as shown in FIG. 8 to control the movement of the block B by applying a pulling force to the wire 300. The movement of the block B is controlled while the tension of the wire 300 connected to the block B is adjusted to control the movement of the block B while the block B is moved to the crane 100, To a predetermined position.

According to an embodiment of the present invention, when the block B moves, the external environment of the block B is measured and the moving state of the block B is adjusted based on the measured external environment, . In addition, the movement of the block B can be minimized by measuring the external environment of the block B, based on which the movement of the block B can be minimized, and the use time of the crane 100 can be shortened. Further, the influence of the surrounding environment can be minimized when the block B moves, and the block B can be seated in the correct position.
