Description

[Detailed description of the device]

[0001]

[Industrial applications]

 According to the present invention, a cable for supplying power, which is provided on a suspender for gripping a heavy object, can be forcibly wound up or pulled up in accordance with the movement of the suspender. The present invention relates to a cable storage basket for heavy equipment.

[0002]

[Prior art]

 Conventionally, in the heavy-duty crane shown in FIG. 4 which is used for unloading a heavy container from a container ship, the lifting device 2 shown in FIG. 5 that holds the container 1 traverses over the crane boom and the girder 6. Although it is suspended from the trolley 4 via a plurality of wires 5 and sheaves, the lifting tool 20 has a high lift H, and is, for example, about 40 m from the ground rail 7 in FIG. When the tool 2 moves up and down and left and right, a power supply cable 8 for supplying electric power to the electric parts of the hanging tool 2 is stored in a cable storage basket 9 provided on the upper part of the hanging tool 2 as shown in FIG. It is designed to be touched and pulled out.

However, when the hanging device 2 traverses while being rolled up from the trolley 4, it may be shaken by wind or the like, so that the power feeding cable 8 may not be properly stored in the cable storing basket 9 and may be scattered outside. The problem often occurs. Since it is difficult to store the cable 8 in the cable storage basket 9 only by the weight of the cable 8, the cable 8 itself is provided with a curl so that it can be easily stored in the cable storage basket 9. If the cable 8 is not properly stored in the cable storage basket 9 and then jumps out to the outside, such a bad habit will be attached to the cable 8 and it will be difficult to store it further. In that case, replace the cable 8 It is uneconomical to do.

Therefore, it is strongly desired to realize such a cable storage basket with a cable forced storage device structure capable of forcibly storing the cable 8 in the busket tab of the power supply cable 8 provided on the hanging device 2 of the crane. Is requested.

[0005]

[Problems to be solved by the device]

 The present invention has been made in response to the above-mentioned strong demand, and is a heavy-weight lifting device that can forcibly store the power feeding cable smoothly in the cable tab when the lifting device moves up and down and traverses. The problem to be solved is to provide a cable storage basket for use.

[0006]

[Means for Solving the Problems]

 As a means for solving the above-mentioned problems, the cable storage basket for a heavy object lifting device of the present invention is rotatably mounted in the center of a cylindrical cable tab provided on the heavy object lifting device. A guide post is provided around the standing rotating shaft, and a rotating plate having a cable inlet is attached to the top of the rotating shaft, and a torque motor that drives this rotating shaft and a rotating plate are installed between the rotating plate and the torque motor. It consists of a clutch that transmits only the rotational force in the direction.

[0007]

[Work]

 In the cable storage basket configured as described above, the feeding cable is guided by the cable introduction port of the rotating plate into the cable tab, and the rotating plate is forcibly rotated by the torque motor to draw in the guide cable inside the cable host. It can be stored smoothly by winding around it, while when the cable is pulled out, the cable is pulled out while rotating the rotating plate in the opposite direction, while the clutch is off and the cable is It will be pulled out without resistance.

【Example】

 Embodiments of the present invention will be described below with reference to the drawings. 1 is a side sectional view of a main part of a cable storage basket according to an embodiment of the present invention, FIG. 2 is a plan view of a main part of a rotary plate in the AA direction of FIG. 1, and FIG. 3 is a BB direction of FIG. It is a sectional side view of a main part of a rotating plate.

First, the cable storage basket is provided above the suspending tool 2 of the container crane as shown in FIGS. 4 and 5, and forcibly stores the power supply cable 8. A rotating shaft 12 rotatably erected by a bearing 11 is provided in the center of the inside of the cylindrical cable tab 10, and a cylindrical guide post 13 is provided around the rotating shaft 12.

Next, a disk-shaped rotary plate 14 is attached to the top of the rotary shaft 12, and a semi-arcuate elongated cable introduction hole shown in FIGS. 2 and 3 is provided on the outer periphery of the rotary plate 14. The port 15 is opened so as to be inclined in the direction in which the cable 8 is introduced, and the guide shoe 17 shown in FIG. 3 is provided inside the cable introduction port 15, and the rotary plate 14 is in the direction of arrow R. When the cable 8 is rotated, the cable 8 is guided by the guide shoe 17 from the cable introduction port 15 and introduced into the cable tab 10 in the direction of the arrow F, and is wound around the outer circumference of the guide post 13 and stored.

A sprocket 18 fixed to the lower part of the rotary shaft 12 and a sprocket 20 fixed to the shaft end of a torque motor 19 for driving the rotary shaft 12 are linked and linked by a chain 21. A clutch 23 is provided between the sprocket 18 and the rotary shaft 12 to transmit only a unidirectional rotational force. In the cable storage basket having the above structure, when the cable 8 for power supply is stored by the movement of the hanger 2, the rotary shaft 12 is rotated by the torque motor 19, and the rotary plate 14 is also rotated together therewith. It is forcibly introduced to the outer circumference of the guide post 13 from the cable introduction port 15 which moves while rotating in the R direction, and is housed.

On the other hand, when pulling out the cable 8 from the cable tab 10, the pulling force of the cable 8 causes the rotating plate 14 to rotate in the direction opposite to the arrow R, at which time the clutch 23 is turned off and the cable 8 is pulled out. Is pulled out without resistance. Although the clutch 23 is provided between the torque motor 19 and the rotary shaft 12 in this embodiment, the clutch 23 may be provided anywhere between the torque motor 19 and the rotary plate 14. For example, it may be provided between the rotary shaft 12 and the rotary plate 14.

[0013]

[Effect of device]

 If the cable storage basket of the present invention described above is provided on the hoisting equipment of a heavy-weight crane, even if the hoisting equipment sways due to wind or the like when the hoisting equipment is moved up and down or traversed, the power supply cable will stay It is forcibly and smoothly stored, it does not come out of the cable tab, the cable can be used for a longer period of time, and it is economical and the work efficiency can be improved.

Particularly, in the present invention, since the rotary shaft is driven by the torque motor, the cable can be wound with a force according to the torque applied to the cable, and the cable is not subjected to an excessive load and is unidirectional. Since a clutch that transmits only the rotational force of the cable is installed, when the cable is pulled out from the cable tab, the rotating plate becomes idle and the cable is pulled out without resistance, so the cable is forcibly stored. On the other hand, there is an advantage that the cable can be pulled out smoothly.

The hoisting tool is one in which a hoisting rope is directly hooked on a spreader as shown in FIG. 5, and one that is composed of a head block h and a spreader s as shown in FIG.
