Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a partition plate for a shovel wheel, and particularly to a support structure for the partition plate.

A shovel wheel has a bucket attached to a rotating wheel, and as the bucket rotates, it scoops up loose tree material and lowers the loose material from the bucket into a chute at the top.

The bucket is closed on the inside to allow the load to be lowered into the chute.

If the load remains in the checkpoint state, the load will fall out during scooping, so the shovel foil has a structure in which the checkpoint is covered with a lining attached to a partition plate from immediately after scooping up to the chute. Due to this structure, friction occurs between the load in the bucket and the lining, and in order to replace the lining, it is necessary to retreat the lining together with the partition plate from the foil to obtain a lining replacement work space.

Conventionally, the partition plate has been pin-coupled to a boom or the like that rotatably supports the foil, that is, a frame that is not affected by the rotation of the foil, and when replacing the lining, the partition plate can be moved from foil to foil around this pin. It was rotated toward the center of rotation and retreated.

According to this method of reversing, equipment such as the boom and chute on the side of the center of rotation of the foil, and the bucket, foil, and arm supporting the foil on the outside become obstacles, cutting a large work space behind the partition plate. Cannot be gained by retreating.

Furthermore, since the working space is inside the foil, the work becomes dangerous. An object of the present invention is to enable easy and safe replacement of the lining attached to the partition plate.

An embodiment of the present invention will be described below with reference to FIG. i to FIG. 3.

This embodiment relates to a reclaimer equipped with a shovel wheel at the tip of a rotating boom.

Bottomless buckets 2 are fixed at regular intervals to the foil 1 which is rotatably supported on the hoop 6.As shown in Fig. 2, bottomless buckets 2 are fixed on the conveyor 7 immediately after scooping. A lining 5 is attached to the outer surface of the partition plate base, and the gap between the lining 5 and the bucket 2 is minimized as shown in FIG. This prevents the load from falling off.Two supports ga and 9P protruding toward the boom 6 side are attached to the partition plate 4 so as to form two upper and lower stages.

As shown in FIG. 3, each of the supports ga and gb has a length that reaches the tip of the boom 6, and an information pipe 9 in a horizontal position is attached to an intermediate portion thereof. This sliding pipe 9 is slidably fitted into a cylindrical guide turtle Q supported horizontally from the tip of the boom 6 by brackets lqa and IQb and parallel to the rotation axis of the wheel 2.This cylindrical guide! As shown in Fig. 3, the length is sufficient to move the partition plate 4 to the position indicated by the two-dot chain line. It is attached to the tip of the shovel by means of a connecting means across the Porto River and is located at the position shown by the solid line.Each support ga, 9b is attached to the bolt 111 when equipped with a shovel wheel or a claimer with such a configuration during cargo handling work. Thus, it is fastened to the boom 6 and becomes the state shown by the solid line in FIG.

Therefore, the entrance portion of the bottomless bucket 2 on the foil 1 side is covered with the lining 5. The section covered by this lining 5 is the same as the section where the partition plate 4 is present, as shown in FIG. For this reason, it is bucket 2, and the lifted load will not be disturbed until it reaches the top of chute 3. Once on the chute 3, the bottom of the bucket 2 is not covered by the lining 5, so the load in the bucket 2 falls into the chute 3 and is conveyed to the destination position by the conveyor 7. Next, when replacing the lining 5, the bolts 11 are unfastened and the sliding pipe 9 is slid on the cylindrical guide 18 in a direction away from the t-wheel.

By this sliding movement, the partition plate 4G integrated with each support 9a, gb is pulled out to the side of the wheel, as shown by the two-dot chain line in FIG. Since there are no obstacles on the opposing surface of the lining 5 at this pull-out position, a space can be obtained in which the hoisting tool of the truck crane can be brought close to the large lining 5 and replacement work can be carried out easily and safely. In particular, even in this moving position, it will be safer if the support parts a and 9b are fastened to the boom 6 with bolts, and then the lining flea is replaced. Further, the bolt 11
When unfastening the bolt 11, the bolt 11 is not located on the projected part of the bucket 2 when viewed from the radial direction of the rotation axis of the wheel cover, but is located on the side thereof (on the side opposite to the foil 1). The bolt 11 can be removed and the lining can be easily assembled after being replaced. In addition, since the partition plate 4 moves parallel to the rotation axis, there is no impact on equipment installed on the boom 6 side, and it can be taken out.The lining light replacement work has been completed. Then, push each support ga, gb toward the wheel turtle side by reversing the above-mentioned pull-out procedure. to conclude.

In this way, the lining 5 is returned to its original state. In this embodiment, each support 9a, gb is pulled out using a sliding means, but a screw feeding means may be used to move each support 9a, 9b to the pulled-out position.

Furthermore, in a bridge reclaimer where the entire shovel wheel moves on a girder while being supported by a trolley, the cylindrical guide IQ may be installed on the trolley frame.

As described above, according to the present invention, the lining of the excavator foil can be moved to a large space while being integrated with the partition plate attached to the lining, and the lining can be replaced. Therefore, the lining replacement work is extremely easy. This can be done easily and safely, and the work of taking out the partition plate is also extremely easy.
