When drag conveyor need be torn chain and chain link open with the extension of digging laneway, chain was broken off at the place at tail, spread the intermediate channel that needs extension, connected chain; The chain of this moment is in relaxed state, and then at the head drum place chain is broken off, and will go up chain and be fixed by bolts on the head side plate; The counter-rotating of crawl motor; When chain gets into critical tensioning state, unnecessary chain is pulled down, then by mechanician's crawl motor counter-rotating; When chain was tensioned under the motor counter-rotating, another mechanician connect the chain that breaks off rapidly.In this process, the mechanician of chain needs quick of eye and deft of hand, accidentally just can lead to the accident that finger is squeezed off.
So how avoid the generation of this type of accident? Analyze the generating process of above-mentioned accident, effectively fixing if we find before mechanician's chain link, the following chain that is in tensioning state to be carried out, then can avoid the generation of this type of accident.At present, various chain tighteners all can carry out effectively fixing to the following chain that is in tensioning state.Yet,, all not very perfect though there is multiple way to solve for fixing of cochain.Analyze will going up chain with bolt and being fixed on the method on the side plate of generally adopting at present, just exist potential safety hazard, be specially and pass the hole on chain link and the headstock side plate to bolt earlier; Tighten with bolt then, then nip off chain, the counter-rotating of crawl motor; With chain tightener following chain is fixed; Pinch unnecessary chain, then chain is connected again, remove bolt at last.In this process, it is insecure with bolt chain being fixed on the side plate, and bolt is easy to broken, and is of long duration, and the hole on head side plate and the head side plate is easy deformation also.So it is necessary designing a kind of simple and safe and reliable resistance chain device.
The utility model content
