It can be one-directionally rotated towards the direction for putting pipe;However with unidirectional 3312 mechanism of pawl the difference is that the ratchet of the positioning mechanism
Also have the non-toothed region being intervally arranged with toothed region on 3311, when continue towards put pipe direction the transfer pipe winding disk when, pawl
3312 can fall into non-toothed region, due to putting only without tooth socket, under 3314 potential energy release action of wind spring, pipe winding disk automatically into
The rotation of row closed tube.It, thereon can be inclined when being touched with the first of toothed region tooth because pawl 3312 is movable rotation connection
Turn direction, that is, beaten from the original optimum position that can be engaged with tooth socket fit, so even if in the automatic closed tube rotation of pipe winding disk
Retainer again passes by toothed region and can not also be engaged by tooth socket in the process.Until entering another non-toothed region on pawl 3312, this
When closed tube work also terminate, need to put again pipe operation when, pawl 3312 pivots under the reset response of spring 3313 so that its
On return to can with tooth socket fit engage optimum position, restore 3311 mechanism of single direction ratchet working characteristics;I.e. on pawl 3312
It can be locked in the tooth socket of 3311 toothed region of ratchet when turntable closed tube rotates, so that turntable can only be single towards the direction for putting pipe
To rotation;Also there is the non-toothed region being intervally arranged with toothed region on the ratchet 3311 of the positioning mechanism, when continuing towards putting pipe
When turntable is transferred in direction, pawl 3312 can fall into non-toothed region, due to putting only without tooth socket, discharge in 3314 potential energy of wind spring
Under effect, turntable carries out closed tube rotation automatically, is off rotation until the block on ground line is limited with gear connection mechanism clamping, from
It is dynamic to complete closed tube;And because pawl 3312 is movable pivot, can be deflected when being touched with the first of toothed region tooth thereon
Direction is beaten from the original optimum position that can be engaged with tooth socket fit, so even if the process rotated in the automatic closed tube of turntable
Middle retainer again passes by toothed region and can not also be engaged by tooth socket;Until entering another non-toothed region on pawl 3312, receive at this time
Pipe work also terminates, and when needing to put pipe operation again, pawl 3312 pivots under the reset response of spring 3313, so that pawl
3312 return to the optimum position that can be engaged with tooth socket fit, restore the working characteristics of 3311 mechanism of single direction ratchet;The pipe winding disk
332 rotate coaxially with the mounting platform 31 and connect;The pipe winding disk 332 is located on the bracket of the mounting platform 31.
