全液压坑道钻机新型夹持器

New clamping device for fully hydraulic pit drilling rigs

特点:1、该夹持器采用双活塞、大行程设计，具有夹持力度强、同轴度好、不易在卡瓦闭合接触面积存煤粉

2、该型夹持器既可夹持光面圆钻杆，又可夹持异型钻杆，还可夹持大叶片螺旋钻杆。

3、该型夹持器与我公司研发的“新型回转器卡盘”配套使用，可在钻杆磨损严重的情况下，仍能夹紧钻杆，从而使钻杆的使用寿命得到延长。

4、可使因摩损而报废的钻杆重新投入使用，也可在使用大叶片螺旋钻杆时，实现机械装卸。

Features:1.the clamp adopts double piston, large stroke design, with strongclamping strength, good coaxiality, not easy to store coal dust in the closingcontact area of the kava.

2. This type of gripper can clamp both smooth round drill pipe and shaped drillpipe, and also can clamp large blade spiral drill pipe.

3. This type of gripper can be used together with the "new type rotary chuck'developed by our company, which can still clamp the drill pipe under thecondition of serious wear and tear of the drill pipe, so that the service life of thedrill pipe can be prolonged.

4. lt can put the scrapped drill pipe into use again due to wear and tear, and itcan also realize the mechanical loading and unloading when using the large-blade spiral drill pipe.
