Be it is simple, advantageously reduce elevator loop chain drive mechanism production cost；Loop chain is wound in the groove of cylinder and is driven,
It is more stable in operation to be conducive to loop chain；And the flange at cylinder both ends, it can prevent chain from deviating from from the end of cylinder.
2. rotating around the axis since flange and shaft are fixed by flat key to limit cylinder, and need not be by cylinder
Wall setting is blocked up to be directly connected to shaft, advantageously reduces the production cost of cylinder.
3. existing since cylinder both ends are by the axial float of round nut and stop washer limitation cylinder to be conducive to loop chain
It is more stable in operation.
4. due to groove be it is arc-shaped, to reduce the mutual loss between cylinder and loop chain.
5. the material of flange is mild steel since the material of cylinder is cast steel, it is ensured that the welding quality of cylinder and flange,
To improve the service life of the utility model.
Detailed description of the invention
Fig. 1 is a kind of structural schematic diagram of embodiment of the utility model connection structure
Main element symbol description is as follows in figure:
In attached drawing, 1- shaft, 2- flat key, 3- cylinder, 4- flange, 5- round nut, 6- stop washer, 7- groove.
Specific embodiment
The specific implementation of utility model is further illustrated below in conjunction with attached drawing.
As shown in Figure 1, a kind of drive mechanism of circular chain bucket hoister, including 3, two flanges 4 of cylinder and shaft 1；Cylinder
Wrapping around for body 3 is provided with the groove 7 that the width of the loop chain of twice width and elevator matches, the central axes of groove 7 with
The central axes of shaft 1 are overlapped, and the centre distance of twice groove 7 is consistent with the centre distance of hopper connecting hole in elevator, cylinder
3 fixing sleeves are set to the outside of shaft 1, and the central axes of cylinder 3 are overlapped with the central axes of shaft 1, and the length of cylinder 3 is less than shaft 1
Length；3 both ends of cylinder are respectively equipped with flange 4, and the central axes of flange 4 are overlapped with the central axes of cylinder 3, and two flanges 4 are distinguished
