Embodiment Construction

[0017] Such as figure 1 , 2 As shown, a multi-layer winding device for coiled tubing used in a "water jet continuous propulsion directional drilling rig" includes: a drilling rig base 16, a frame 15 connected to the base, and a drum 1 supported on the frame by a drum rotating shaft 14 , and steel pipe pressing mechanism 3, power mechanism 13. The drum rotating shaft 14 is connected with the power mechanism 13 through the drum driving clutch 12, the drum rotating shaft 14 and the drum 1 are connected with the frame drive shaft 11 through the transmission mechanism, and two traveling gears 5 are respectively fixed at both ends of the frame drive shaft 11. , and is mounted on a pair of racks 4 on the rig base 16 for meshing transmission to drive the frame 15 to move.

[0018] The transmission mechanism includes: the drum sprocket 17 is coaxially connected with the drum rotating shaft 14, and is transmitted through the chain 6 and the frame driving sprocket 18, the frame driving...

Abstract

The continuous tubular multi-layer winding apparatus is one kind of super-deep drilling apparatus for underground mineral exploitation, geological exploration, oil and gas exploitation, etc. The available single-layer winding apparatus limits the super-deep drilling construction. The continuous steel tube multi-layer winding apparatus consists of winding roller, frame, driving mechanism and power transmission gear, gear rack, etc. and is matched with steel tube driving apparatus to realize continuous steel tube multi-layer winding. The present invention makes it possible to increase greatly the continuous steel tube winding length without increasing the roller width.

Description

technical field [0001] The invention belongs to the field of machinery, and relates to the field of ultra-deep drilling construction such as mining drilling for underground solid minerals, geological surveying, oil and gas mining, and the like. Background technique [0002] In mining engineering, geotechnical engineering, construction engineering and other fields, it is often necessary to construct horizontal holes or directional deep holes to achieve special purposes. For example: it is used for the advanced gas drainage in the down-trough tunneling of the underground mining face, and the gas drainage of the working face is carried out by using the down-trough; it is used for the prevention and control of coal seam rock burst and other geotechnical engineering construction directional drilling and pressure relief and rock breaking. The "water jet continuous propulsion directional drilling rig" device disclosed in the application number 031227333 is a device specially used f...
