Description

Technical Field

[0001] The invention belongs to the technical field of chain manufacturing, and in particular relates to a movable hydraulic segmentation and ring connection device for large-size chains. Background Art

[0002] Chain drive is a key form of mechanical transmission. Roller chains generally consist of five major components: inner and outer plates, pins, sleeves, and rollers. The pins and outer plates form the outer end segments through an interference fit, while the sleeves and inner plates form the inner end segments through an interference fit. The rollers fit over the pins, and multiple inner and outer end segments are connected one by one to form the entire chain.

[0003] At present, for small size chain, there are manual disassembly and mechanical disassembly two modes, for large size 40A and above specification chain owing to being used on large equipment more, the extrusion force needed is large, be not suitable for adopting manual and mechanical disassembly, because the extrusion force of the chain pin and chain plate, sleeve and chain plate of 40A and above specification is larger, manual disassembly is difficult to provide enough extrusion forces, and manual disassembly needs to knock with hammer and easily cause parts damage simultaneously. In addition, the chain of large size 40A and above specification in prior art is because its weight is heavier, volume is larger, does not carry out loop connection when chain is shipped, needs to carry out loop connection or disassembly according to actual length when chain is installed; Yet most chains of the prior art are all to carry out loop connection or disassembly after disassembly by mechanical disassembly (being about to chain hoisting on fixed device) in chain manufacturer, ship again, this just directly caused the chain of large size 40A and above specification not to have corresponding equipment to carry out disassembly and loop connection, loop connection, disassembly work inconvenience.

[0004] In addition, when the chain is disassembled or connected in the prior art, the chain is not easily fixed, resulting in poor fixing effect. As a result, the chain may move during processing, causing the chain to be damaged due to improper force when disassembling or connecting. Summary of the Invention
