Description

Pin replacement device for chain connection {APPARATUS FOR REPLACING CHAIN CONNECTING PIN}

The present invention relates to a chain link pin replacement device used in a conveyor belt chain for mainstream transport, and more specifically, to a chain link for mounting a new pin more easily while removing the chain link pin to be replaced more easily. For a pin replacement device.

Chains are also called chains. From large ships 5 to 6 cm thick and 500 to 600 m long for ship mooring, to small ones such as necklaces used for tall ships. The chain not only has a wide range of uses, but also has various shapes.

Industrial chains are widely used for mooring ships, for chain blocks and cranes for lifting loads, and for power transmission of various machines. Such chains have great flexibility as a whole and are convenient for winding objects.

However, for tensioning, such as cable cars and ropeways, long ones are required. In this case, weight is a problem and steelmaking is used.

Another feature of the chain is that the length can be easily adjusted by removing the hook, and when it is worn, only the part can be replaced.

Mooring and tensile chains are usually made of mild steel, malleable cast iron and cast iron. The shape is oval, rectangular or reinforced with a cross in the middle of them.

In the case of making a chain, in the case of mild steel, the ring is first made by forging, another mouth is opened, the other loop is inserted, and the gap is folded. Repeating this task creates a long chain. In the case of cast iron, two cast rings are placed in a mold and a third ring is cast to connect the two.

In addition, the ship chain is large in size, and anchoring chains, steering chains used for steering, and transport mechanisms for unloading are used for mooring. Since anchor chains and the like are related to the safety of ships, rules are established for the dimensions, length, strength, etc. of the chains.

In addition to general chains, there are roller chains and silent chains for power transmission chains. Inexpensive ones such as pin chains are used for low speeds.

Long chains have been used with gold chain necklaces since the 4th and 5th centuries BC. Goldsmiths were inherited by many people and gradually progressed from ancient to middle ages, resulting in highly elaborate tall chains.

In the old days, gold strings (chains made of gold) were used equally as money and were a property. From around 1830, customs of winding long gold bands around the neck have been created.

The strings are made of gold, silver, and platinum, and are currently used as ornaments for women's necklaces, bracelets, and bracelets.

The chain is connected and connected by a pin for chain connection, and the pin for chain connection is manufactured in the form of pins of the same thickness, and produced by caulking both ends of the pin for chain connection.

When the speed of the power transmitted to the chain is a high speed, there is a problem that the chain is broken or burst, and the chain is difficult to operate at high speed, causing a safety problem.

Chains are also used in many steel mills. For example, the conveyor and the bucket elevator of the cooling bed and the material input device are operated by a chain.

However, due to the characteristics of the steel mill, the size of the chain used is very large because the items to be handled are almost large and heavy, and the connection state through the pin is also very solid.

In the prior art, there are many difficulties in replacing the pin for chain connection for chain coupling.

When disassembling and assembling the chain, it is very difficult to insert or retract the chain connecting pin.

In particular, in the case of severe rust occurs, even if a strong price with a hammer does not fall out to fix the situation is severely cut by the oxygen welding machine.

Therefore, there is a problem in that the chain is removed by disassembling, dismantling, replacing the damaged parts with new parts, reassembling, and mounting the device again in a very difficult and time-consuming manner.

In addition, since the wear pins and chains of the chain connecting pins become more severe as the chain is used for a long time, the chain connecting pins should be replaced periodically.

Since the chain link pin is firmly and tightly coupled to the pin hole of the chain, it is not easy to remove only the chain link pin without deforming the chain. In particular, chains are prone to damage by hand using hammers or other tools.

Also, removing the chain connecting pin and inserting a new chain connecting pin again is not easy. The pin holes of the chain must be exactly matched so that the chain connecting pin can be inserted and can be inserted without damage.

In order to remove the chain connecting pin, the pin was removed by using a punch having the same size as this pin, and the pin was removed. Therefore, if the strike point is missed during the removal of the chain connecting pin, the worker's hand and foot are hit. There is a problem causing a safety accident.

As described above, even when a skilled person performs the removal of the chain connection pin, safety cannot be guaranteed and the removal of the chain connection pin is delayed.

In particular, the conveyor belt chain for liquor transport, such as shochu, beer, beverages, etc. used in the liquor manufacturing plant has too much load applied to the chain when the liquor is transported out of the box, and wear of the chain connecting pin is very severe.

Such a fast and fast chain connecting pin has a lot of work to replace by hand and the chain has to be replaced often.

In addition, since the conveyor belt chain for mainstream transport depends entirely on imports, there is a problem in that foreign currency and waste of resources are also severe.

On the other hand, the existing pin replacement device for chain connection is mainly made of the replacement pin removal operation and the replacement pin insertion operation. In this case, there is a problem that the chains are easily distracted after the pin is removed and a lot of time is required for the replacement work.

On the other hand, the chain link pins are mainly made of steel, which is often rusted. In this case, smooth movement of the chain may be interrupted by rust. And there is a problem that the rust spread to the chain to remove both the chain and the chain connection pin of the rusty portion.
