Horizontal hole or inclined hole drilling tool lifting system

Abstract

The invention discloses a lifting system of a horizontal hole or inclined hole drilling tool. A first fixed pulley, a second fixed pulley and a third fixed pulley are installed above a bottom frame, wherein the first fixed pulley is located at the end away from a drilled hole, and the second fixed pulley and the third fixed pulley are equal in height and located on the side close to the drilled hole. A winch is installed in the middle of the bottom frame. When the drilling tool needs to be conveyed to the drilled hole, one end of a first steel wire rope is fixed to the winch, and the other end of the first steel wire rope winds around the first fixed pulley and then is connected with one end of a triangular connecting ring; a second steel wire rope sequentially winds around the second fixed pulley, a notch of a special joint and the fixed pulley, and then the two ends of the second steel wire rope are connected with the other two ends of the triangular connecting ring in a one-to-one corresponding mode; when the drilling tool inside the drilled hole needs to be lifted out of the hole, one end of the first steel wire rope is fixed to the winch, and the other end of the first steel wire rope is arranged on a bolt of the special joint in a sleeving mode. The lifting system can be used for conveying or taking out drilling tools of different lengths, can greatly improve the working efficiency and lower labor intensity of workers, and is convenient to operate, safe, reliable and small in occupied area.

Description

technical field [0001] The invention relates to the field of geological drilling engineering, in particular to a lifting system for lifting and lowering drilling tools during horizontal hole or inclined hole drilling construction. Background technique [0002] At present, there is no special lifting system for lifting and lowering drilling tools for horizontal or inclined holes. The general practice is: [0003] First, when a traditional vertical shaft drilling machine is used, the drilling tool is completely extracted from the hole manually or forced into the hole manually. [0004] Second, when a power head type drilling rig (top drive type drilling rig) is used, the power of the power head is used to press-feed or extract the drilling tools one by one into the hole. [0005] There is a problem: [0006] 1. Manually conveying or pulling out the drilling tool, because the resistance of the horizontal hole or the inclined hole is extremely large, it needs many people to wo...

AI Technical Summary

Problems solved by technology

[0006] 1. Manually conveying or pulling out the drilling tool, due to the large resistance of the horizontal hole or the inclined hole, it needs multiple people to work together, which is extremely labor-intensive, low in efficiency, and unsafe

[0007] 2. The power head (top drive) drilling rig lowers or extracts the drilling tool. Although the labor intensity is low, due to the limited length of the active drill pipe of the drilling rig (generally about 3 meters), only one 3 meters can be drawn out (or fed) each time. Not only is the efficiency extremely low, but also the drill pipe larger than 3 meters cannot be pressed (or pulled out)
