Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to, for example, an automatic method in which a long material such as a steel pipe is hung by a sling wire and is carried into a hold by using a quay crane, and the wire bead removing work is automatically performed without manpower. The present invention relates to a hanger with a wire ball removing mechanism.

[0002]

2. Description of the Related Art Conventionally, as a hanging tool for suspending a plurality of steel pipes by a slinging wire and carrying it into a hold by using a quay crane, the wire bead removing work is automatically performed without manpower, as shown in FIG. A hanger 170 with an automatic wire ball removing mechanism described in JP-A-2-33087 is known. Although the slinging work of the slinging wire is performed by the operator on the quay, the slinging off work of the slinging wire inside the hold is dangerous work.
This suspension is used. The hanging tool 170 with the automatic wire ball removing mechanism is a long hanging beam 171 that can be hung by a quay crane (not shown), and a hanging beam 171.
Is provided with a pair of automatic wire bead removing mechanisms 172 provided at a lower end portion thereof at predetermined intervals in the longitudinal direction. In the automatic wire bead removing mechanism 172, the mounting body 17
The one end of the sling wire 175 is connected to the pin 174 provided on the No. 3 via the hanging alloy tool 176, and the other end of the sling wire 175 is rotated in the plane perpendicular to the mounting body 173 via the hanging alloy tool 177. It is detachably provided on a suspension hook 178 that is movably provided. Hanging hook 1
On the base side of 78, a retaining means 180 is provided via a pin 179.
Is rotatably attached, and a pin-shaped protrusion 181 is provided at the tip of the retaining means 180. The rotation lever 183 is rotated by the electric motor (not shown) via the rotation shaft 182, and the disengagement prevention means 180 shown by a solid line
The protrusion 181 is rotated in the clockwise direction, and further, the retaining means 180 shown by the broken line is rotated together with the hanging hook 178 so as to be in the wire removing position. Reference numeral 184 in FIG. 9 indicates a position detecting protrusion provided on the rotary lever 183, and reference numeral 185 indicates a position detecting sensor.

[0003]

However, the above-described conventional hanging tool 170 with an automatic wire bead removing mechanism still has the following problems to be solved. Since the automatic wire bead removing mechanism 172 having the hanging hook 178 is directly fixed to the hanging beam 171, since the distance between the steel pipe 186 to be handled and the hanging beam 171 is short, the hanging beam 171 is attached to the opening side wall at the upper part of the hold. As a result, the slinging / packing work on the inner end side of the hold is difficult and dangerous, and the ship and the hanger 17
0 was severely damaged, causing trouble. Further, since the suspension beam 171 is heavy and swings, it is dangerous for an operator to approach the suspension beam 171. In particular, the scaffolding is unstable in the work in the hold, and the danger is high. Further, since the suspension beam 171 is simply provided with the pair of automatic wire bead removing mechanisms 172 and the slinging wire 175, there is also a problem that the transport efficiency of the steel pipe 186 is poor. Further, since the electric motor is used to rotate the suspension hook 178, power supply from the quayside crane is required, which requires modification work on the quayside crane.

The present invention has been made in view of the above circumstances, and it is possible to suppress damage to a ship and a hanger, to improve transport efficiency, to perform a safe work, and to reconstruct an automatic lifting machine. An object is to provide a hanger with a wire ball removing mechanism.

[0005]

According to the present invention, there is provided a lifting tool with an automatic wire bead removing mechanism according to the above object, in which a hanging wire for hanging both ends of a long material is manually hooked on a hanging hook and lifted. Transport long materials using heavy equipment,
A hanging tool that automatically removes a sling wire from a hanging hook.A hanging beam that can be hung by a lifting machine, a hanging line that is hung on the left and right sides with a predetermined interval in the hanging beam, and a hanging wire. And an automatic wire bead removing mechanism provided with a hanging hook that is hung on the lower end of the rope and is rotatable in a vertical plane.
As a result, an automatic wire bead removal mechanism is provided through the hanging rope suspended on the suspension beam.For example, when loading in the hold, a heavy suspension beam must contact the side wall of the opening. It has a flexible hanging line and a lightweight automatic wire ball removing mechanism even if it comes into contact,
Moreover, the sling wire can be automatically removed from the hanging hook in the hold.

In the hanging device with the automatic wire bead removing mechanism according to the present invention, it is possible to provide a plurality of sets of hanging ropes and automatic wire bead removing mechanisms on both left and right sides, and further to make it possible to adjust the distance between the hanging ropes. As a result, a large amount of long material can be handled at one time, and long materials having different lengths can be handled. In the hanging tool with the automatic wire ball removing mechanism according to the present invention, the hanging hook of the automatic wire ball removing mechanism is driven by an air actuator,
The suspension beam may be provided with an engine generator and an air compressor driven by the engine generator, and compressed air generated by the air compressor may be supplied to the air actuator via a hose and a solenoid valve.
As a result, it is not necessary to feed power from the lifting machine side to the main suspension, and the automatic wire bead removing mechanism can be made compact.
