Detailed Description

As shown in figures 1 to 9, a novel step chain is maintained to convenient maintenance of steady operation, it sets the integrated configuration of unilateral chain to the convenient compound mode of dismantling through, can carry out the selection installation of different positions different order as required when the installation, the flexibility during installation is stronger, through setting up U-shaped attaching plate structure on every off-axis festival, can ensure that the installation intensity between the chain link is better, the dismantlement during later maintenance is more convenient, can play better protection to chain link mounted position in the use, make holistic operation stationarity better, thereby the whole durability of chain when using has been improved, the security in the use is higher. The step chain comprises step chain main body structures which are symmetrically distributed front and back, the front and back two groups of step chain main body structures are connected together through a hollow step shaft 26, the connecting positions of the step chain main body structures and the hollow step shaft 26 comprise inner chain plates 1, sleeves 2, spacer bushes 3, a main wheel 4, retainer ring pin shafts 5, first retainer rings 6 and first oil cup assemblies 7, the chain link combination positions adjacent to the connecting positions of the hollow step shaft 26 comprise second retainer rings 8, guide wheel connecting pins 9, guide wheel main bodies 10, second locking nuts 11, flat washers 12, U-shaped attached plates 13, third locking nuts 14 and fastening screws 15, the second retainer rings 8, the guide wheel connecting pins 9, the guide wheel main bodies 10, the second locking nuts 11 and the flat washers 12 are connected together in a combined mode, the U-shaped attached plates 13 are located on the inner sides of the guide wheel main bodies 10 and face the direction of the hollow step shaft 26, the U-shaped attached plates are connected with the connecting positions of the inner chain plates 1 at adjacent positions through D-shaped pin shafts 16, outer chain plates 17, shaft chain plates 18 and connecting rings 19 are combined together through interference fit through the guide wheel shaft sleeves 30, and the guide wheel shaft sleeve assemblies 9 are connected together.
