ZFY series inverse well drilling rig (AT series raise borer) is absorbing domestic and overseas drilling experience, achieve advanced leading level in China.

At present, ZFY series inverse well drilling rig has released ZFY1.2/30/150 (AT1200), ZFY1.4/40/200 (AT1400), ZFY1.5/35/200 (AT1500), ZFY1.8/40/250 (AT1800), ZFY2.0/50/200 (AT2000), ZFY2.5/105/200 (AT2500), ZFY3.0/120/200 (AT3000), ZFY3.5/150/400 (AT3500) and other models for mass production. ZFY series inverse well drilling rig (AT series raise borer) is the national "seven, five" key scientific and technological projects, it was awarded the first prize of progress of science and technology by Ministry of coal, and in 1991 approved by the National Quality Certification Committee, won the "National Quality Award", and it was listed as national new technology, new product "pushing" project.

ZFY1.2/30/150 (AT1200), ZFY1.4/40/200 (AT1400), ZFY1.8/40/250 (AT1800), ZFY2.5/105/200 (AT2500) inverse well rig (AT series raise borer) has been passed through the national "coal mine safety mark" certification, and achieved a certificate issued by national mine product safety standards sign center.

Products have been widely used in the coal mine, metal mine, water conservancy and Hydropower Engineering and other fields, praised by the majority of users, and achieved good economic and social benefits.

Main structure and working principle

Main structure: ZFY series inverse well drilling rig (AT series raise borer) generally consists of two parts: the host part and assembly parts.

1.1 Part of the host

The host part comprises of frame, hydraulic pump station and the operation control system. Therack is frame structure, inside provides with power water tap, under the action of hydraulic cylinder the power tap move up and down along the slide rail of the framework, hydraulic pump station and the operation control system are used to drive rig operation, in order to achieve different requirements of drilling technology in different conditions.

1.2drill part, includes open hole drill pipe, stable drill pipe, normal drill pipe, guide hole drill bit and reamer bit.

2, ZFY series inverse well drilling rig (AT series raise borer) working principle:

The main drive of rig transmit to drilling system through the dynamic water tap, drives the guide hole drill bit and reamer bit to rotate. cone of guide hole bit or the hob on reaming bit impact,extruding or cutting the rock in the drilling pressure to crush rock. Broken rock debris during drilling was discharged out of the hole outside by circulating water or mud, when drilling cuttings directly onto the water gate road, loading machinery transport or other transport vehicles transport them away from the slag site. Guide hole drill by the upper level to downward level, expanding pull the position from downward level to upward level.

Uses and characteristics

ZFY series (AT series raise borer) is efficient drilling equipment (ore bin, ventilation hole, pressure piping,electricity and equipment works well). It has the characteristics of lower case:

1, the rig pushing and pulling force, torque, speed and main parameters design are reasonable, simple drilling process, it can satisfy the different geological conditions and construction requirements of various aperture;

2, Adopts full hydraulic pressure drive, compact structure, light weight, power;

3, rig installation, transportation and adjustment are all mechanization, it has the advantages of simple, save labor, fast, safe, no need auxiliary equipment;

4, hydraulic system is simple and reliable, easy to operate, most of the hydraulic element adopts famous brand components, convenient repair and replacement;

5, the drilling process achieves mechanization operation, simple, safety, improve working conditions, and reduce labor intensity;

6, the drill pipe threads is API international standard, safety and reliability, good interchangeability, long service life, rig tool assemble and unassembled has reasonable process, auxiliary time is short, the rig is equipped with open hole drill pipe and stationary drill pipe, which can effectively prevent hole deviation;

7, the rig has strong applicability, it can construct in complex geological conditions;

8, the drilling rig is explosion-proof type, suitable for all levels of combustible gas environment;

9, drilling efficiency is high, drilling speed, good quality.

ZFY series inverse well drilling rig (AT series raise borer) construction experience

1: The wide using geological scope: suitable for various rock hardness F3 - F14, for the hard rock F12 ~ 14 (compressive strength of 1200 ~ 1400kg/cm2) can be custom-made to meet the special cutter breaking rock.

2, applicable to a variety of pore size, depth and angle: direct installation in ready foundation and chambers without other auxiliary equipment, according to different geological conditions, select relevant pressure or tension, torque to drill, the operation is simple and convenient, firstly drill down a hole, run through to the lower level, remove the pilot hole bit, reaming upwards to upper level then get well completion

Requirements to the users:

We will send engineer after the rig reached at the user spot in drill assembly, debugging, and learning theory, the operation training. After the operation and repair Participants can carry out after passing the rig test and other professional work.
