Description

[Detailed Description of the Invention] This invention relates to an elevator system in which a multi-layered loading cage is attached so as to be rotatable up and down, and more particularly to a bearing device in which the loading cage is swingably attached to the tip of an attachment.

Figure 1 is a conceptual diagram of an elevator with a loading cage;
2 and 3 show a conventional bearing device. A guide 4 is provided between a chain wheel 2 and a chain wheel 3 provided above and below a tower 1, and a main chain 5 is suspended between the chain wheel 2 and the chain wheel 3 through the guide 4. The main chain 5 has an attachment link 6 and a specified number of plain links 7.
The loading cages 9 are suspended via bearing devices 8 which are arranged at the ends of the attachment links 6 and are removably provided on the tip ends of the attachment links 6. In the bearing device 8, an oil-impregnated bushing 11 and a felt ring 12 are fitted into a cast yoke 10 held by the attachment link 6, and the loading cage 9 is rotatably supported by the oil-impregnated bush 11.

However, since the cast yoke 10 has many finishing parts for assembly, it is time-consuming to manufacture. Large fillets and thick walls are required to ensure safety, which adds extra weight. The shape of the material is fixed, making it difficult to reuse. It had drawbacks such as poor flexibility and difficulty in assembly.

In view of the above-mentioned drawbacks, the object of this invention is to provide a bearing device having a steel plate welded structure that eliminates these drawbacks.

The configuration of this invention will be explained based on the drawings of the embodiment. FIG. 4 shows the front of the bearing yoke 16 of the present invention, and FIG. 5 shows the side and the direction of the DEF arrow. In FIGS. 4 and 5, face plates 14 are welded to both ends of the plate-shaped spacer 13 so as to face each other, and the face plates 14 in contact with the side surfaces of the protruding ends of the attachment links 6 are removably fixed. A bearing yoke 16 is constructed by welding a support cylinder 15 across the end. An oil-impregnated bush 11 and a felt ring 12 for a bearing for rotatably supporting the loading cage 9 are fitted into the support cylinder 15 in parallel with the connecting pin of the attachment link b, thereby forming a bearing device. .

The plate spacer 13, the face plate 14, and the support cylinder 15 are made of the material of the bearing yoke 16 with high precision, reducing the number of finished parts, eliminating waste, and increasing flexibility compared to the past. It exhibits speedy manufacturing, weight reduction, and ease of assembly.

The bearing yoke is attached to the face plate 1 as shown in Figures 6 and 7.
You are also free to change it to 4-A.

As explained above, this invention combines a bearing yoke with a steel plate and a tube in a welded structure, thereby reducing the number of finishing parts, reducing weight, and making it possible to create a flexible bearing device.

Claims (1)

[Scope of utility model registration request] In a chain type elevator in which a loading part is suspended from the tip of an attachment link, a bearing yoke for attaching the loading part is provided which is removably fixed to the side surface of the tip of the attachment link, and one end of the bearing yoke is attached to the attachment link. The face plates are opposed to each other so as to be in contact with the side surface of the protruding end of the main chain, and one end of the opposing face plate is fixed via a plate-shaped spacer.On the other hand, a bearing for the loading cage is installed in the support cylinder, and the axis of the bearing is aligned with the main chain. A bearing device characterized in that a support tube is fixed to the other end of an opposing face plate so as to extend parallel to the connecting pin.
