XY-1A Crawler Mounted Drill Rig Introduction

Xy-1a drilling rig is a hydraulic feed portable drilling rig, 150 meters drilling depth ,150mm hole diameter , It is a kind of hydraulic feeding, high speed, high speed torque belt and portability with pump.which is suitable for engineering geological exploration of industrial and civil buildings, railways, hydropower, transportation, bridges, dam foundations and other buildings.

XY-1A Crawler Mounted Drill Rig Tech Data

XY-1A Crawler Mounted Drill Rig Advantages

1. It has a hydraulic automatic feeding mechanism to improve drilling efficiency and reduce labor intensity.
2. It adopts the ball card clamping mechanism instead of the chuck, and can implement the non-stop bar, easy to operate, safe and reliable.
3.The hoist is equipped with a frame to form a double-sided support star structure that can withstand strong impact.
4.Four sets of bearing positioning of the vertical axle box ensure that the gyrator has sufficient rigidity to deal with complex geological conditions such as gravel layer and pebble layer.
5.This machine adopts a taper clutch, which has the characteristics of large transmission torque, convenient operation and maintenance-free.

XY-1A Crawler Mounted Drill Rig Application 

XY-1A drilling rig is mainly used for geological general investigation and exploration, road and tall buliding foundation exploration, kinds of hole in concrete structure, river levees,earth temperature central air-conditioner,etc.XY-1 Series are spindle core geotechnical drilling rigs most perfectly suitable for borehole drilling in geo-construction and geo-technical exploration drilling in projects like civil building, construction of railway, hydropower, highway, bridge and dam etc.

Core Tube - Coring Tool

1. Single layer core pipe

The single pipe drilling tool has simple structure and convenient processing. It is a common coring tool for hard alloy and steel particle drilling. The flushing liquid in the single pipe drilling tool is sent into the core pipe by the drill pipe. The drill accessories that directly rush to the top of the core, and the impact and friction of the core caused by the rotation of the core pipe, are very easy to wear and tear the core, so they are only applicable to relatively complete and stable formations.

2. Double core tube

The double-layer core pipe is formed by adding a core containing pipe (inner pipe) to the original core pipe (outer pipe). According to whether the inner pipe rotates during drilling, it can be divided into two types: double acting and single acting:

Double layer double acting core tube (double acting double tube) - the outer tube rotates and the inner tube also rotates.

Double layer single acting core tube (single acting double tube) - the outer tube rotates but the inner tube does not rotate.

The double-layer core pipe can isolate the scouring effect of the washing liquid on the core. Double acting double pipe water isolation without vibration isolation, used for soft, loose and easily eroded formations; The single acting double pipe can isolate water and vibration, . Basically, the drill accessories of single acting double pipe drill are used for diamond drilling.
