Swing ring plate structure for the construction heavy}

The present invention relates to a swinging plate structure, more specifically

Bend one belt-shaped plate to form a swinging plate, and have a ring-shaped swinging support plate to install the swinging plate on the top of the swinging body at regular intervals to correct the smoothness of each conventional part. It is possible to reduce the work process for doing so, it is possible to reduce the work time and cost, and in particular, the manufacturing cost is not generated because the raw material portion was not generated by processing the unit plate having a certain curvature in the plate of a predetermined area It further relates to a swinging plate structure for heavy construction equipment that can further reduce the cost, as well as smoothness can be easily corrected to improve the reliability of the product.

In general, in the case of construction heavy equipment such as an excavator, it is provided with a turning body provided above the wheel body running on the track, and the driver's seat of the excavator is left and right by allowing the driven body such as the driver's seat connected to the turning body to rotate. It is to be able to play the role of turning movement.

Here, a component called a swinging plate is essentially provided among the elements constituting the structure of the swinging structure, which is to support the swinging body when rotating the driven body such as an excavator driver's seat, which is one of construction heavy equipment. The cylindrical body is fixed to the center of the support hull that covers and supports the upper wheel body forming the trajectory of the track, and the swinging plate is welded and fixed to the upper end side of the cylindrical body.

Such a swinging plate has a structure in which a swing drive part including a ring gear is connected to the upper side of the swing ring plate, and is connected to a driven body in construction heavy equipment such as a swing drive part and an excavator, and in FIG. 1, an example of such a swing drive part is shown. Is a schematic drawing.

As shown in FIG. 1, a strip-shaped plate contacting the lower end of the ring gear 1 formed as the lower end of the swing driving part is the swinging plate 10 referred to in the present invention.

As one of the methods for obtaining the swinging plate 10, as shown in FIG. 2, the plate-like material 10b having a desired size is cut by CNC machining or the like, and each unit plate 10a is formed in an arc shape. After obtaining, the unit plate 10a is subjected to grinding treatment, and then welded to the end side of each unit plate 10a to obtain the completed swinging plate 10 having a circular arc shape.

Therefore, when such a work process is performed, the plate-like material 10b is cut and processed by CNC machining by a predetermined curvature to obtain each unit plate 10a, as shown in FIG. In addition, the welding process is performed between the unit plates 10a obtained by each cutting process, and the machining time required by the CNC machining cutting and the welding process of each welding part has been pointed out. .

Reference numeral A means a weld.

In addition, the swinging plate obtained after the welding treatment of a plurality of welding spots to be obtained should obtain excellent smoothness due to the exact welding state, the smoothness may appear different depending on the skill of the worker in the process of work, reducing the reliability of the product There is a problem that is thrown away.

In addition, it is possible to implement the swing plate of the exact circular shape only by obtaining the unit plate by the same curvature, it can be different to obtain the unit plate having the exact curvature and length of each unit plate according to the operator's skill In the process, it is difficult to realize the swinging plate of the correct circular shape, or it is inconsistent, and it is necessary to have a post-process which requires the CNC machining cutting work to be performed again. Is accompanied by.

On the other hand, such a bending technique has often bent small parts having a small diameter, but there was no example of bending and processing a large part such as a swinging plate of a large construction device such as a construction machine. When the thickness was larger than the width of the plate to bend, no bending was found.
