According to the anti-loosening high-strength welding chain, along with relative movement between the pin shaft and the sleeve as well as between the pin shaft and the chain plate, the oil storage cotton ring and the fan-shaped oil storage block can be extruded, lubrication is continuously released to lubricate the pin shaft, meanwhile, the oil storage cotton ring further plays a role in sealing the sleeve, small-particle matter is prevented from entering the sleeve to increase friction, and in a non-working state, the anti-loosening high-strength welding chain is not damaged. And the lubricating oil in the sleeve can be repeatedly absorbed by the fan-shaped oil storage blocks to be repeatedly utilized, so that a long-term lubricating effect is achieved.

Description

Technical Field

[0001] The present invention relates to the technical field of chain equipment, and specifically to an anti-loosening high-strength welded chain. Background Art

[0002] A welded chain is a chain formed by connecting chain links through a welding process, and is widely used in fields such as lifting, hoisting, towing, ships, mines, ports, etc. Its structure is firm, the load-bearing capacity is strong, and it can adapt to high-strength, heavy-load and harsh working conditions.

[0003] Traditional welded chains are difficult to be effectively lubricated under actual working conditions, which affects their service life. Summary of the Invention

[0004] (I) Technical Problems to be Solved Aiming at the deficiencies of the prior art, the present invention provides an anti-loosening high-strength welded chain, which solves the problem that it is difficult to effectively lubricate the connecting chain under actual working conditions, affecting its service life.

[0005] (II) Technical Solutions To achieve the above objectives, the present invention is realized through the following technical solutions: It includes a plurality of connecting units. The connecting unit includes a chain plate, a pin shaft and a sleeve. There are two chain plates in a single connecting unit. The two chain plates are distributed in a V-shape. A sleeve is arranged between the two chain plates. The sleeve is internally penetrated with a pin shaft. Both ends of the pin shaft penetrate through the chain plate. Adjacent two connecting units are connected through the pin shaft and the chain plate. A plurality of fan-shaped oil storage blocks are fixedly connected to the inner side wall of the sleeve. The plurality of fan-shaped oil storage blocks are distributed in an annular array. One side of the plurality of fan-shaped oil storage blocks far from the inner side wall of the sleeve is fixedly connected with a negative pressure plate.

[0006] Preferably, a horn-shaped oil inlet hole is opened inside each of the plurality of negative pressure plates.

[0007] Preferably, two oil storage cotton rings are fixedly sleeved on the outer surface of each of the plurality of pin shafts. The oil storage cotton rings are located between the chain plates of adjacent two connecting units.

[0008] Working Principle: When in use, with the relative movement between the pin shaft and the sleeve and the chain plate, the oil storage cotton rings and the fan-shaped oil storage blocks will be squeezed, continuously releasing lubricant to lubricate the pin shaft. At the same time, the oil storage cotton rings also play a role in sealing the sleeve, preventing small particle substances from entering the inside of the sleeve and increasing friction. In the non-working state, the lubricating oil inside the sleeve will be repeatedly absorbed by the fan-shaped oil storage blocks for repeated use, achieving a long-term lubricating effect.

[0009] (III) Beneficial Effects The present invention provides an anti-loosening high-strength welded chain. It has the following beneficial effects: As the relative movement occurs between the pin shaft, the sleeve and the chain plate of the anti-loosening high-strength welded chain, the oil storage cotton ring and the sector oil storage block will be squeezed, continuously releasing lubrication to lubricate the pin shaft. At the same time, the oil storage cotton ring also plays a role in sealing the sleeve to prevent small particulate matter from entering the inside of the sleeve and increasing friction. In the non-working state, the lubricating oil inside the sleeve will be repeatedly absorbed by the sector oil storage block for repeated use, achieving a long-term lubrication effect.
