The rear portion of weight frame and the balancing weight is detachably connected.Balancing weight is detachably connected with counter-balanced carriage and headstock front end, any group
Part damages replaceable, and practicality is good.
Further, the counter-balanced carriage and the dilatory locomotive head front end bolt connection.
Further, the rear portion of the balancing weight is provided with groove, the balancing weight and counter-balanced carriage and is provided with what is be mutually matched
Pin-and-hole, the counter-balanced carriage is caught in the balancing weight and by inserting the installation pin connection of the pin-and-hole.
Compared with prior art, the beneficial effects of the utility model are:Traction fixation kit detachably connects with balance weight assembly
Connect, therefore traction fixation kit is quick detachable and changes;The front end of balance weight assembly is by through hole or gap for the fixed group of the traction
The connecting bolt of part stretches into horizontal neck and is connected with the fixture block in it:Set through hole advantage be, the front end of balance weight assembly
Good integrity, the ability for bearing pulling force is more preferable, while being hardly damaged when the manufacture of its easy processing and drawing;The excellent of gap is set
Point is, without screwing out and (need to only unscrew) connecting bolt from fixture block completely, you can traction fixation kit is overall from described
The side of balance weight assembly is pulled out, and is also more facilitated during installation, only needs the overall insertion from balancing weight side to screw again.
