Claims

[Scope of utility model registration request]

This is an automatic drive roll pitch changing device for a tube insertion device for inserting tubes into a large number of holes in a tube plate, baffle plate, etc. provided in a heat exchanger, seawater desalination equipment, etc. Of these, the central drive roll is fixed to the drive shaft, each of the left and right drive rolls is fixed to one end of a multi-sleeve attached externally to the drive shaft on the left and right sides of the drive shaft, and the other end of the multi-sleeve is fixed to the drive shaft. coupled to the drive shaft or the sleeve via a screw, and the multiple sleeves are interlocked and connected to the rotation of the drive shaft via a clutch, and the screws are configured to have opposite threads on the left and right sides of the drive shaft;
A spur gear having the same diameter from the drive shaft center is provided on each of the drive shaft and the multiple sleeve, and an idle gear for fixing at a pitch that engages and disengages from the teeth of the spur gear to enable the multiple sleeve to rotate integrally with the drive shaft. An automatic drive roll pitch changing device for a tube insertion device, characterized in that it is provided with:
