Specific embodiment
As shown in Figs 1-4, it is a kind of elevator stair transmission shaft fixed device of the invention, including step 1, is set on step 1
It is equipped with transmission shaft 2, offers axis hole on step 1, transmission shaft 2 is from passing through axis hole and be connected with chain drive in its end, ladder
Grade 1 drives transmission by transmission shaft 2, is additionally provided with the guide post 3 being firmly connected with it on step 1, further includes connecting plate 4, even
Fishplate bar 4 is that integral type or dismountable structure are set on guide post 3 and transmission shaft 2, and are fixed on step by bolt 5
1 (step 1 only depicts the schematic diagram connecting with 2 coupling part of transmission shaft and side with connecting plate 4 in figure, the other side and its
Structure is identical) on, lubricating structure is additionally provided between transmission shaft 2 and connecting plate 4.
The dismountable structure of connecting plate 4 is, connecting plate 4 includes the first half plates 41 and the second half plates 42, the first half 41 Hes of plate
It is provided with the semi-circular through hole 43 to match respectively with guide post 3 and 2 diameter of transmission shaft on second half plates 42, the first half 41 Hes of plate
The second half plates 42 are bolted on step 1 after blocking guide post 3 and transmission shaft 2, and connecting plate is arranged to removable two
A half hardened structure, installation that can be more convenient and flexible, when installation, by the first half plates 41 and the second half 42 middle section of plate weights
It is folded that (i.e. the area of the first half 41 middle sections of plate is greater than the area or the first half 41 middle parts of plate of the second half 42 middle sections of plate
Point area less than the second half 42 middle sections of plate area) and then be fixed by bolts on step 1, connection can be increased
The structural strength of whole 2 part of intermediate supports transmission shaft of plate 4 is (at this point, the position of transmission shaft 2 may be provided at the upper of guide post 3
