At toppling for trolley 1.
For 1 even running of trolley, upper roller device 12 includes symmetrical upper roller pair.Upper roller device 12 also wraps
Include the upper roller shaft 121 being fixed on trolley 1 and the upper rolling in the axis hole of two upper rollers of upper roller centering or so
Wheel bearing 122.Upper roller by upper roller bearing 122 to being nested in the left and right ends of upper roller shaft 221.As an alternative,
Two upper rollers of upper roller centering or so may be also secured on upper roller shaft 221, and upper roller shaft 221, which is inserted into, is mounted on trolley 1
Upper roller axis hole in upper roller bearing 122 in.For the purposes of 1 even running of trolley, rolled in front and back two groups of the setting of trolley 1
Wheel pair.
Similarly with upper roller device 12, bottom roller device 13 also includes symmetrical bottom roller pair.Preferably, bottom roller
Pair with upper roller to being aligned up and down.The position that 1 bottom of trolley corresponds to bottom roller pair is additionally provided with bottom roller holder 15, bottom roller pair
Each bottom roller is mounted on 1 bottom of trolley by bottom roller holder 15.Bottom roller can be eccentric roller, can adjust it is eccentric from
And adjust upper laminating degree between bottom roller and track 5.Bottom roller device 13 further includes the bottom roller being fixed on trolley 1
Axis and the bottom roller bearing in the axis hole of bottom roller.Two bottom rollers of bottom roller centering or so are respectively by respective
Bottom roller bearing be nested on the bottom roller axis of the left and right on being fixed on bottom roller holder 15 two.As an alternative, lower rolling
Wheel centering or so two bottom rollers can also be separately fixed on two bottom roller axis, and two bottom roller axis are inserted into respectively to be mounted on
In two bottom roller bearings in two bottom roller axis holes of bottom roller holder 15.With front and back two groups of upper rollers to corresponding up and down
Ground, in the two groups of bottom rollers pair of front and back setting of trolley 1.Intermediate chain wheel device 3 can be between front and back two groups of bottom rollers pair.Buffering
Device 4 can be located at intermediate chain wheel device 3 and between the pair of rollers of 212 side of the second drive sprocket.
Corresponding to the left and right quantity of two idler wheels to two idler wheels in left and right and bottom roller with upper roller, the quantity of track 5 is
Two.
Fig. 6 A be feed system shown in Fig. 2 in chain front view, wherein also show intermediate chain wheel device, sliding block,
Fixed block and chain guide.Fig. 6 B are the vertical view of chain shown in Fig. 6 A, wherein also showing chain guide.Such as figure
Shown in 6A and Fig. 6 B, when chain guide 221 is installed below to hold chain 22 in chain 22, avoids chain 22 long under chain 22
It hangs down.Since the strength of the transmission carrying of chain 22 is larger, generally use multiple rows of chain 22 shows 3 row chain items 22 in Fig. 6 B.If
Chain is multiple rows of chain 22, and chain guide 221 is installed below to hold chain in two rows of chains 22 in outside in multiple rows of chain 22
22, chain 22 is sagging when avoiding chain 22 long.
