The invention provides a lifting structure for a drilling tool mounting rack. The lifting structure comprises a driving part, a lifting rope and a pulley assembly, and the driving part slides in the horizontal direction; one end of the lifting rope is connected with the driving part, and the other end of the lifting rope is connected with a drilling tool mounting frame; the lifting lifting rope comprises a first lifting rope acting on the upper end of the drilling tool mounting frame and a second lifting rope acting on the lower end of the drilling tool mounting frame, and the first lifting rope and the second lifting rope are connected with the two ends of the driving part respectively according to the movement direction of the driving part; the pulley assembly is used for changing the walking direction of the lifting rope, and under the action of the driving part, the first lifting rope and the second lifting rope jointly act to enable the drilling tool mounting frame to complete the lifting action. According to the lifting structure, the lifting lifting rope and the pulley assembly structure are adopted for completing the lifting action of the drilling tool mounting frame, resonance generated in the working process of the drill bit is effectively avoided through the flexibility of the lifting rope, and then the phenomenon that the drill bit is broken in the working process is effectively avoided.

    本申请提供了一种用于钻具安装架的升降结构,包括驱动部、升降吊绳和滑轮组件,驱动部在水平方向滑动;升降吊绳一端与驱动部相连,升降吊绳另一端用于与钻具安装架相连;升降吊绳包括作用于钻具安装架上端的第一吊绳、作用于钻具安装架下端的第二吊绳,按照驱动部的运动方向计第一吊绳和第二吊绳分别与驱动部的两端相连;滑轮组件用于改变升降吊绳的行走方向,在驱动部的作用下,第一吊绳和第二吊绳共同作用使得钻具安装架完成升降动作。本申请中的升降结构采用升降吊绳、滑轮组件结构完成钻具安装架的升降动作,利用吊绳的柔性有效避免钻头在工作过程中产生共振,进而有效避免钻头在工作过程中发生折断的现象。
