BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a hoist used when a long steel material such as an H-shaped steel, an I-shaped steel, a steel pipe, a steel sheet pile and the like is transported by a crane.

[0002]

2. Description of the Related Art When a long steel material such as an H-shaped steel, an I-shaped steel, a steel pipe and a steel sheet pile is conveyed by a crane, conventionally, the long magnet is attached directly to a lifting magnet attached to a hook of the crane. Or a long beam suitable for these steel materials is suspended from a crane, and a wire rope or a chain is slung at an appropriate interval from the beam to be lifted. JP-A-5-126666
FIG. 1 is a diagram described as a description of the prior art
1, shown in FIG.

[0003] 1 is a beam material, 2 is a hanging part, 83 is a mounting bracket, 84 is a wire rope, and S is a long steel material. Such a slinging operation must be performed manually, and for example, in the lifting stage, it is necessary to hold the wire rope by hand until the wire rope is not loosened, which is a low workability and dangerous work. Therefore, an attempt has been made to automate the slinging operation and to transport the long steel material only by remote control from the crane cab. For example, according to the above-mentioned JP-A-53-126663, as shown in FIG. 13 and FIG. An automatic sling hanging device has been proposed.

FIG. 13 is a side view showing the entire automatic sling hanging apparatus, and FIG. 14 is a front view of a main part thereof. The automatic sling hanging apparatus is provided with a beam member 1 suspended from a hook of a crane. A non-bend back chain in which a slinging chain 97 is provided so as to be able to be pulled out and pulled out from one leg 96 of a gate-shaped frame 95 suspended at a desired position, and is bent to one side but not to the other at the other leg 98. When the non-bend back chain 99 is sent out, it is advanced toward the opposing leg end to engage and connect with the chain 97, and the non-bend back chain 99 is pulled in for slinging. The long steel material is held in the space between the legs 96 and 98 by bridging the chain 97 between the opposing legs.

[0005] If such an automatic sling hanging device is used, the slinging worker becomes unnecessary, and productivity and safety are improved. However, due to the shape characteristics of long steel materials, in general, it is rare that a suspended load is accumulated and transported to the full lifting capacity of a crane, and in most cases, the transport unit is determined due to dimensional restrictions on the form of loading. is there. For this reason, the efficiency of cargo handling by a crane or the like does not increase, which is one of the causes of prolonging the berthing time of a ship in the case of loading.

Accordingly, the present applicant has developed a "transport rack" capable of handling such a long steel material in a large amount in a lump, and has been disclosed in Japanese Utility Model Laid-Open No. 5-162828. This transport rack will be described with reference to FIGS. FIG. 15 is a front vertical sectional view of the rack body 61, and FIG. 16 is a pair of rack bodies 61.

Is configured as described above, when the rack bodies 61 are stacked in the vertical direction, the protrusions of the vertical members 65 of the lower rack body fit into the cutouts of the vertical members 65 of the upper rack body. In addition, a large number of rack bodies 61 can be stably stacked in a hold or a truck without causing collapse of the load.

Further, the present applicant has developed a lifting device for lifting such a transport rack by a crane, and has been disclosed in Japanese Utility Model Laid-Open No. 5-64182. Fig. 17
This will be described with reference to FIG. FIG. 17 is a side view showing an embodiment of the lifting device, FIG.
FIG. 6 is a side view of another embodiment of the lifting device.

This lifting device uses a plurality of rack body exclusive hanging members 32 each having an engaging portion 33 which is engaged with a vertical member 65 of a rack body 61 shown in FIG. The beam 1 is provided on the upper surface thereof with a hanging portion 2 connected to a crane or the like. The front view of FIG. 18 shows a state in which the rack body 61 and the rack body dedicated hanging tool 32 are engaged. In other words, below the rack-specific hanging tool 32, the play portion is provided in accordance with the interval between the side beams 63 of the rack body 61.
An engagement portion 33 including two plates separated by a pin 34 and a pin 35 inserted therethrough is provided. As can be easily understood from the drawing, the rack-specific hanging tool 32 is hung down, the loose portion 34 is fitted to the vertical member 65 of the side beam 63 of the rack body 61, and the pin 35 is engaged with the vertical member 65. The rack body 61 is inserted through the hole 66.

It is desirable that the motor 71, the screw shaft 72, the guide rod 73, and the like have a structure in which the mounting position of the rack-type dedicated suspender 32 to the beam member 1 can be adjusted.

[0011]

As described above, various means have been proposed for transporting a long steel material without manually performing the slinging operation as described above, accumulating a considerable amount of material and improving the volumetric efficiency. When these long steel materials are sorted into lots, dimensions, destinations, and other transport units on the production line, they can be shipped by transport racks as described above, and can be directly linked to freight wagons without using the racks. Or it is common to mix things with shipping. However, since these require the use of different lifting gear, it is necessary to replace the lifting gear on the crane each time, which not only reduces the efficiency of the crane but also in some cases extends to the production line. It could be a hindrance and improvements were desired.

[0012] The present invention is to provide a long steel hanging material which can select and lift a long steel material housed in a rack body and a tied steel material at any time without such replacement work. With the goal.
