Description

[Detailed Description of the Invention] [Industrial Application Field] This invention relates to a device for fixing a rope in a hoist drum or the like.

[Conventional technology]

Conventionally, this type of device was, for example,
There was something like the one shown in Publication No. 12276. FIG. 6 shows a conventional device, in which 1 is a drum with a spiral groove formed on its outer periphery. 2 is a rope such as a wire that is wound along this spiral groove, and at its tip there is a rope end 3 whose diameter is slightly larger than the diameter of the rope.
is formed. 4 is a slightly larger diameter right-angled hole used when inserting the rope end 3, and 5 is an inclined hole formed in the right-angled hole 4 in the axial direction of the drum 1, so that the wire rope 2 is larger than the right angle. It is constructed by drilling a hole in it. The inclined hole 5 has a diameter smaller than that of the rope end 3 and larger than that of the wire rope 2, and is formed in a protruding boss 6 formed on the inner surface of the drum 1. Furthermore, this inclined hole 5 is inclined with respect to the diametrical line.

[Problem that the invention attempts to solve]

By the way, since the conventional apparatus is constructed as described above, it is necessary to provide two right-angled holes, resulting in high costs and problems such as an increase in the overall length of the drum.

This invention was made to solve the above-mentioned problems, and aims to provide a rope fixing device for a hoist drum, etc., which can shorten the overall length of the drum and simplify its shape.

[Means for solving problems]

The rope fixing device according to this invention has a drum in which winding grooves are formed on both sides except for the central part, and a rope is formed in the central part with a diameter larger than the outer diameter of the rope end fitting, and the drum is penetrated through the drum. Do 1
a pair of openings formed with a smaller diameter than the outer diameter of the rope end fitting, extending continuously in the axial and circumferential directions on both sides of the right-angled holes, and forming a substantially U-shape when viewed from the front; A locking portion is formed in the drum so as to face each of the pair of openings, and is capable of locking the rope end fitting.

[Effect]

In this invention, two rope ends can be locked by providing one right-angled hole in the drum, making the work easier and making it possible to shorten the length of the drum.

〔Example〕

An embodiment of this invention will be described below with reference to the drawings. In Figures 1 to 5, 1 is a drum;
A spiral groove is formed on the outer periphery except for the central part. Reference numeral 2 denotes a rope such as a wire that is wound along this spiral groove, and a rope end 3 having a slightly larger diameter than the rope is formed at its tip.
40 is a right-angled hole provided in the center of the drum 1 through the drum wall, and this hole has a slightly larger diameter than the rope end 3 so that the rope end 3 can be inserted therein, as shown by the broken line in FIGS. 3 and 4. is being done. 5
0 and 60 are inclined holes formed on both sides of the above-mentioned right-angled hole 40 in the axial direction of the drum 1 by recessing the drum wall.
It has a diameter larger than the diameter of. The shape of the inclined holes 50, 60 is approximately U-shaped when viewed from the front, as shown in FIGS. 1 and 2, and the vertical cross section is as shown in FIG. 4, and the horizontal cross section is as shown in FIG. There is. Reference numerals 50a and 60a are a pair of openings which are opened in a predetermined range in the circumferential direction of the drum 1, and 50b and 60b are locking parts of the rope end fitting 3 formed in the drum 1 corresponding to these respective openings.

The engagement between the rope 2 and the inclined holes 50, 60 is achieved through the third
As shown in Figures 5 to 5, the rope end 3 is inserted into the hole 40 perpendicular to the circumferential direction of the drum 1 (indicated by a broken line in the figure), and then the rope end 3 is inserted into the inclined hole 40.
It moves in the 0 and 60 directions, respectively, and is locked in the state shown in FIG.

[Effect of idea]

As described above, according to this invention, only one right-angled hole needs to be provided on the drum, which simplifies construction, and the overall length of the drum can also be shortened, reducing the cost of this type of device. .

[Brief explanation of the drawing]

Fig. 1 is a front view showing an embodiment of this invention, Fig. 2 is a front view showing an enlarged view of the hole, Fig. 3 is a sectional view taken along the line - Fig. 2, and Fig. 4 is Fig. 3. -A cross-sectional view along the line, Figure 5 is Figure 4-
6 is a side sectional view showing a conventional rope fixing device. In the figure, 1 is a drum, 2 is a rope, 3 is a rope end fitting, 40 is a right-angled hole, 50 and 60 are inclined holes, 50a and 60a are openings, and 50b and 60b are locking portions. Note that the same reference numerals in the figures indicate the same or corresponding parts.
