Abstract

PURPOSE: To allow a wire rope end supporting member to be easily fitted in a short time and a wire rope to be wound from the center part of a drum by disposing and fixing the wire rope end supporting member on the inside of a drum center rectangular hole. CONSTITUTION: A stationary plate provided with an insert hole (b) for a wire rope end 3, oblong holes (e) for moving a wire rope 4, and a lead-out groove for the wire rope 4 is bent, and the oblong holes (e) for moving the wire rope 4, and a supporting plate provided with a mounting part C of the wire rope end 3 are rigidly fixed and integrated to form a wire rope end supporting member. This wire rope end supporting member is put inside a drum 1 from a drum center rectangular hole (a), and the periphery of the center rectangular hole (a) is welded and rigidly fixed (h). Accordingly, even in the case of the drum 1 being large in inner diameter D and long in the whole length or small in inner diameter D, the wire rope end supporting member can be easily fitted in a short time, and the wire rope 4 can be wound from the center part of the drum 1.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a wire rope terminal support structure for a drum a in a hoist, where the wire rope terminal is wound from the center of the drum.

[0002]

2. Description of the Related Art When winding a wire rope 4 around a drum 1, a wire rope end mounting hole g is used in the case of a normal hoist, but as a special product, the wire rope 4 is mounted at the center of the drum 1 as shown in FIG. When the drum 1 is wound from a portion, if the inner diameter D of the drum 1 is large and the length thereof is short, the wire rope terminal support member can be attached as shown in FIG. If the inner diameter D is small, the wire rope terminal support member cannot reach the mounting portion during the mounting work shown in FIG. 6, so a special jig or the like must be used, which is extremely difficult work.

Further, quality inspection after work has been difficult (Japanese Patent Laid-Open No. 62-23715).

[0004]

As described above, according to the conventional technique, the wire rope 4 is wound from the central portion of the drum 1, and the wire rope terminal supporting member is structurally unfit due to the dimensional limitation of the drum 1. Sometimes it was possible.

[0005]

The wire rope end supporting member shown in FIGS. 5 to 8 is arranged inside the drum central square hole a of the drum 1 and fixed as shown in FIGS.

[0006]

The wire rope terminal supporting member shown in FIGS. 5 to 8 is arranged and fixed inside the drum 1, and the wire rope terminal 3 is inserted through the insertion hole b and moved to the wire rope terminal mounting position C. Thus, as shown in FIG. 1, the wire rope 4 is wound from the center of the drum 1.

[0007]

EXAMPLE A fixing plate 5 having an insertion hole b of the wire rope terminal 3, an elongated hole e for moving the wire rope 4 and a drawing groove J of the wire rope 4 is bent as shown in FIG. The wire rope terminal supporting member (FIGS. 5 to 7) integrally formed by fixing the supporting plate 6 and the supporting plate 7 provided with the moving long hole and the mounting portion C of the wire rope terminal to the drum central square hole a.
The drum 1 is further placed inside and arranged as shown in FIGS. 1 and 2, and the periphery of the drum central square hole a is welded and fixed h.

The drum 1 thus constructed has a quality because the wire rope terminal supporting member can be easily attached in a short time even when the inner diameter D of the drum 1 is large and the overall length is long, or when the inner diameter D of the drum 1 is small. A stable drum support structure can be obtained.

[0009]

According to the present invention, the wire rope terminal supporting member can be easily attached to the central portion of the drum 1 even when the inner diameter D of the drum 1 is small or the total length is long.

Further, the wire rope 4 can be wound from the center of the drum 1.
