Problems solved by technology

Due to the long mast and heavy weight, the center of gravity of the equipment is forward when the vertical mast is tilted backward, and the stability is reduced. Insufficient system pressure to complete pole
After the pole, if you want to impose a follower frame, you must use an aerial work vehicle to send the installer to work at a height of about 20 meters above the ground when installing and disassembling the follower frame. The operation is very difficult and increases the assembly time. Hazard and assembly cost

Abstract

The invention discloses a detachable follow-up frame and an installation process thereof. The detachable follow-up frame comprises two sliding lugs (1), a supporting frame (2), a supporting disk (3), a rotary support (6) and a nylon sliding plate (4), wherein one end of the supporting frame (2) is connected with the supporting disk (3) through a first pin shaft (5) and the other end of the supporting frame (2) is connected with the sliding lugs (1) through a second pin shaft (8). By the detachable follow-up frame, the perpendicularity precision of a formed hole of a rotary drilling rig is improved; the number of deflected holes and the number of waste holes are reduced; the drilling cost is saved; and the construction progress is guaranteed. The problem that the follow-up frame of the large rotary drilling rig is inconvenient to install can be solved.

Description

technical field [0001] The invention relates to a follower frame of a piling machine, in particular to a dismountable follower frame for a rotary drilling rig, especially a large rotary drilling rig whose mast is tilted forward during transportation. The invention also relates to the installation process of the detachable follower frame. Background technique [0002] When the rotary drilling rig is drilling, there are two ways to ensure the vertical accuracy of the hole: one is to use the extended power head to drive the key sleeve to directly guide the drill pipe vertically to form a hole; Support, the outer ring of the slewing ring is connected with the drill pipe connecting plate, the inner ring is fixed with a special frame, the other end of the frame is a sliding lug, and the nylon slider is installed on the inner side of the sliding lug to connect with the mast guide rail and slide with the guide rail (referred to as follower frame) . The distance from the center of ...
