Specific embodiment
Come below in conjunction with the accompanying drawings technical scheme is further elaborated.
Referring to shown in Fig. 1 to Fig. 2, a kind of above-mentioned chain tension mechanism, in frame 1, for chain drive
In chain carry out tensioner, chain drive includes chain ringwise, at least two rotations in frame 1 and be located at
Be used for the sprocket wheel of tension chain inside chain, this chain tension mechanism include guide rail 3 in frame, can be along guide rail 3
The slide block 4 on guide rail 3 that length bearing of trend slides, one of sprocket wheel is the first sprocket wheel 2, and this first sprocket wheel 2 can
Around the rotation of Pivot Point Center line direction on slide block 4, chain tension mechanism also includes driving slide block 4 to slide on guides 3
Make the first sprocket wheel 2 near the telescoping cylinder 5 of chain, in frame 1, telescoping cylinder 5 includes cylinder body 52 and external part to this telescoping cylinder 5
51, this external part 51 is mutually fixedly connected with slide block 4.In this embodiment, guide rail 3 has two, and slide block 4 is the cunning through this guide rail 3
Block bearing, the first sprocket wheel 2 around Pivot Point Center line rotate on this slipper bearing.
This chain tension mechanism also includes storing the oil tank 6 of hydraulic oil 61, is provided with check valve 7 between cylinder body 52 and oil tank 6
With stop valve 8, one end of check valve 7 and stop valve 8 is respectively connected with cylinder body 52 phase pipeline, check valve 7 and stop valve 8 another
One end is respectively connected with oil tank 6 phase pipeline, and when chain tension mechanism is in running order, check valve 7 is opened, and stop valve 8 closes
