Description

[Detailed Description of the Invention] The present invention is designed to reduce wear and smooth operation of the conveyor chain without reducing the strength of the conveyor chain when the conveyor chain runs and meander within its U-shaped guide rail. This invention relates to a conveyor chain meandering prevention device.

Conventional = Generally speaking, as a meandering prevention device for conveyor chains,
As shown in Figures 1 to 3, the conveyor chain a is
When the conveyor chain is operated in a meandering manner within a letter-shaped guide rail b, both sides d of the loaf e of the conveyor chain are guided by low both-side guides e of the guide rail b, or relatively high both-side guides, or the conveyor chain is guided by a relatively high both-side guide e. A sliding plate g or a protrusion is separately provided on the side of the link plate f of a, and the sliding plate or protrusion is used to slide on both side walls i of the U-shaped guide rail.

However, in the former case, the conveyor chain cannot run smoothly and reliably unless the diameter of the rollers of the conveyor chain is made large and the guides on both sides are made high, making it economically expensive, and in the latter case, welding defects may occur when protruding sliding plates or protrusions are installed. This often caused accidents such as conveyor chains breaking.

The present invention solves these problems by forming chamfered portions on the side ends of a pair of pin link plates of a conveyor chain and providing a U-shaped cross section for guiding the conveyor chain. Meandering of the conveyor chain is prevented by sliding both side walls of the guide rail below the connecting pin of the pin link plate over the entire lateral side of the link plate.

Next, to explain the first embodiment shown in FIGS. 4 to 6, the conveyor chain is constructed as follows: a pair of pin link plates 1, 1 and a pair of butt shrink plates 2. The bushings 3 and 2 are arranged alternately in a straight line, and the bushings 3 are arranged on the bushing shrink plates 2, 2.
The connecting pin 4, which is rotatably inserted into the bushing 3, is fitted into the pin link plates 1, 1 so that one end becomes a head and the other end is locked by a retaining pin 5. At the same time, a roller 6 for supporting the chain is rotatably attached to the outer periphery of the bush between the bush link plates 2 and 2 in contact with the guide rail, and the pin link plate 1,
1 and the upper surface of the buttu shrink plates 2, 2 (5th,
6) A support member 8 is fixed via the slats 7 by means such as bolt nuts or welding, and chamfered portions 9, 9 was established.

The guide rail 10 for guiding the conveyor chain configured as described above extends in the running direction of the chain, and has a substantially U-shaped cross section, with a flat part 11 for receiving the rollers 6 of the chain and a pin. It has side walls 12, 12 surrounding the link plate, and the height of the side wall is higher than the lower surface of the link plate so that it can slide over the entire lateral side of the link plate below the connecting pin 4. This is what I did.

In the present invention constructed as described above, a plurality of conveyor chains and guide rails are arranged in parallel.

A long hot slab (approximately 10
00℃) (not shown), but during this transportation process, the slab cools down and due to heat contraction, a thrust force is applied in a direction perpendicular to the direction of travel, causing the chain to The chain is forced to meander, and the chain is therefore strongly pressed against the side wall of the guide rail, but the side wall of the guide rail supports the entire lateral side of the link plate below the connecting pin of the pin link plate. Therefore, the contact area is large, so the contact stress is small, and the chain can withstand thrust force sufficiently. The chain can be operated with reduced wear without reducing the strength of the chain and without causing accidents such as breakage due to the pin link plates. Since the conveyor chain can be used in forward and reverse directions, even if there is a step or joint in the middle of the guide rail, the end of the link plate will be caught at that point due to the chamfered part. This will not cause any additional tension to be applied to the chain.

Although this embodiment has been described with respect to a conveyor chain for slough conveyance, it is of course applicable to other conveyor chains that receive a thrust force in a direction perpendicular to the direction in which the chain travels.

Next, the second embodiment shown in FIGS. 7 to 9 will be described.
The conveyor chain includes a pair of pin link plates 1',
1' and a pair of butt shrink plates 2't2' are arranged in parallel in a straight line alternately, and the butt shrink plates 2, 2
The ends of the bush 7 are fitted and fixed, and the connecting pin 4' rotatably inserted into the bush is fitted into the pin link plates 1', 1' with the ends serving as heads. The ends are locked with the retaining pin 5', and the pin link plates 1', 1'
A chamfered portion 9' is provided at the tip of the chain in the direction of travel on the side opposite to the butt shrink plates 2' and 2', and the guide rail 10' that guides the chain A flat part 1 extends in the direction, has a substantially U-shaped cross section, and receives the lower surfaces of both the pin link plate and the butt shrink plate of the chain.
1' and a side wall 12' surrounding the pin link plate, 1
2', and the height of the side wall is such that it can contact the entire lateral side of the link plate below the connecting pin 4, thereby preventing the chain from meandering.

This embodiment has the same functions and effects as the first embodiment of the rabbit, and the chamfered portions 9' of the pin link plate are provided at both the front and rear ends so that it can be used in both forward and reverse directions. You can also do this.
