ある。[Detailed Description of the Invention] The present invention relates to a reversing device for steel blocks, etc. equipped with magnets, which is used as assembly equipment for large structures such as ship hull blocks. The purpose of this is to reduce the weight of the reversing device by using one side of the connected and integrated member of the reversing device as the yoke of the magnet, and configuring the magnet by providing inner and outer poles, excitation coils, etc. on the yoke. The aim is to reduce the amount of electricity and equipment costs.

くならざるを得なかつた。 Conventionally, in a reversing device used in this type of large structure assembly equipment, if the reversing device is equipped with a magnet, a plurality of magnets are required, and in order to connect these magnets, the reversing device is used as shown in Figure 1. A magnet m was connected to a connecting member a of the device with a bolt b or the like. For this reason, the connecting member a had to be strong enough to withstand the weight of the hull block held by the magnet m and the weight of the magnet m itself, which meant that the device had to be large and heavy. .

ので、以下図面を参照して説明する。 The present invention is an improvement on the above-mentioned known technology, in which one side of the connected and integrated member is a yoke, inner poles are arranged in a row at regular intervals on the yoke, and outer poles are continuously formed on both sides of the inner pole. It is characterized in that a coil is disposed around each of the inner poles, and the outer pole and the inner pole form one suction plane, which will be explained below with reference to the drawings. .

と内極４とで一つの吸着平面を形成している。 Reference numeral 1 denotes an arm composed of an integrally connected member, and one side of the arm also serves as the yoke of the magnet. 2 is a magnetic yoke consisting of one side of arm 1. Reference numeral 3 denotes an outer pole of a magnet formed continuously on the yoke, and is provided on both sides of the inner pole 4. The inner poles 4 are arranged in a row at regular intervals at the center of the yoke 2. Reference numeral 5 denotes excitation coils of a magnet, which are arranged on both sides of the inner pole 4. 6 is a magnet coil protection plate. and the outer pole 3
and the inner pole 4 form one adsorption plane.

る。 In addition, Fig. 2 shows the case where the arm 1 has an I-shaped cross section, and Fig. 4 shows the case where the arm 1 has an H-shaped cross section and the second
This is a case where the upper part of the arm also serves as the outer pole 3 in the figure.

強度面の補強の役目も兼ねることになる。 The present invention has the above structure, and one side of the arm 1 is also used as the yoke 2 of the magnet, so the outer pole 3 of the magnet constitutes the original magnetic circuit of the magnet, and at the same time serves as a part of the arm 1 to provide strength. It will also serve as surface reinforcement.

このため従来の連結部材とマグネツトを個別に
連結する構成のものに較べ大巾に重量が軽減され

マグネツトと連結部材とを個別に連結する構成の
ものの合計重量約18tに対し、本考案の一体構成
としたマグネツトアームの場合には約14.5tとな
り、大体20％程度の重量軽減が可能となる。 Therefore, the weight is significantly reduced compared to the conventional structure in which the connecting member and the magnet are connected separately. For example, in the case of a reversing device for a 40t hull block,
The total weight of a structure in which the magnet and the connecting member are connected individually is about 18 tons, while the integrated magnet arm of this invention weighs about 14.5 tons, making it possible to reduce the weight by about 20%. .

本考案によればアームとマグネツトの重量を大

む。 FIG. 6 shows an example of assembling a hull block using the reversing device according to the present invention. In the figure, reference numeral 10 denotes a base material, and the base material 10 is transported in the direction of the arrow on a trolley and held by suction on the reversing device A according to the present invention. Next, the suctioned material is inverted (arrow X), placed on the reinforcing material 11 arranged in advance, and welded together. Once welded, it is turned again in the direction of the arrow y and sent to the next process.
