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 disassembly and assembly type follow-up frame and an installing technology thereof. The disassembly and assembly type follow-up frame comprises two slide lugs (1), a supporting frame (2), a supporting tray (3), a rotating support (6) and a nylon slide plate (4). One end of the supporting frame (2) is connected with the supporting tray (3) through a first pin shaft (5). The other end of the supporting frame (2) is connected with the slide lugs (1) through second pin shafts (8). By means of the disassembly and assembly type follow-up frame and the installing technology thereof, vertical accuracy of hole forming of a rotary drilling rig is improved, hole shift and abandoned holes are reduced, hole drilling cost is saved, and the construction progress is guaranteed. The current situation that a follow-up frame cannot be conveniently installed on a large machine type rotary drilling rig is avoided.

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 the 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 o...
