Further, for realizing the length travel compensation of drilling rod in lifting process, be provided with two leads at the top of framework, compensating plate, Compress Spring and stop nut from bottom to top are housed on two leads successively, described suspension hook is loaded on the compensating plate.
Further, be to guarantee the present invention and the even running of drilling rod in lifting process, be provided with pulley bracket and the pulley that matches with derrick in a side of framework, thereby make framework in lifting process, realize steady lifting by guide rail and pulley along derrick.
Further, bump with other parts after entering the framework inner chamber for preventing drilling rod, above slips, be provided with the drilling rod fairlead.
Further, enter smoothly framework for making drilling rod, the framework below slips is provided with flaring drilling rod introducing port.
Beneficial effect of the present invention is: rational in infrastructure, easy to operate, effectively reduced labor strength, and improved operating efficiency and security reliability.
