Crawler type fully hydraulic variable diameter directional drilling rig for coal mines

ZYWL-6500DB crawler-type fully hydraulic variable-diameter directional drilling rig for coal mines is a new type of general-drilling upgraded directional drilling rig recently developed by our company. It is mainly used for coal mine gas drainage drilling construction, and can also be used for various types of high-precision short- and medium-distance directional drilling construction within 350m, such as underground water exploration and drainage, geological structure and coal seam thickness detection, coal seam water injection, roof (bottom) slab grouting, etc. , the drilling rig adopts a split structure and is mainly composed of the main engine of the drilling rig, a mud pump truck, a measurement while drilling device, a variable-diameter grooved auger drill pipe, etc.

This drilling rig has the following advantages:

The drilling rig adopts an advanced load-sensitive system, which can accurately control the feed pressure and rotation pressure, and has the characteristics of energy saving, high pressure control accuracy and overload protection;
It has a horizontal azimuth angle of 0~180° and an angle adjustment range of ±90°, which can meet the requirements of various construction angles and has a wide range of applications.
(3) The oil cylinder propulsion mechanism is adopted to provide long stroke, smooth propulsion and high transmission efficiency, which improves the drilling rig's ability to deal with accidents such as drill holding and stuck drill in the hole;

(4) Both the chuck and the holder are made of high-pressure-resistant and wear-resistant rubber sleeves, which are made of imported polyurethane and have long service life, high reliability and low replacement rate.

(5) Use advanced large-flow mud pumps with small size, high pressure, stable flow, low noise and high reliability.

(6) The independently developed wireless measurement while drilling device has stable signal transmission. The signal is transmitted in the form of electromagnetic waves. Ordinary sealed drill pipes can be used for drilling, reducing construction costs.

(7) The measurement while drilling device transmits the inclination angle, azimuth angle, tool roll angle, instrument temperature, battery voltage and other parameters of the drill bit in the form of extremely low-frequency electromagnetic waves. At the same time, it can realize real-time display of the drilling parameter trajectory, and can adjust the bend according to the situation in time. Head direction to achieve precise directional drilling. Signals are automatically analyzed during the construction process without manual intervention.

(8) Both the power head and the front holder of the variable diameter directional drilling rig have the ability to adapt to drill pipes with a diameter difference of 20mm between the joint and the rod body. Slips are no longer frequently replaced during operation. The structure is mechanical and the clamping force is large.

(9) Variable diameter grooved auger drill pipe: The whole rod joint structure is that the joint diameter is larger than the rod diameter. Structural advantages: While the strength of the joint and rod body is fully guaranteed, the flexibility of the whole rod is improved, which facilitates the bending of the drill rod in the hole and changes in drilling. trajectory. For example, for a drill pipe with a diameter of 73, the joint size can be up to a diameter of 89, which means that it has the performance of a drill pipe of 89, and the rod body has better curvature than that of a drill pipe of 89.
