Double boom drilling rigs for tunnels, underground mines
Product introduction of drilling rig
TZ2S double-arm rock drilling rig is mainly used for tunneling, underground mines and other underground works in tunnels and tunnels. , duct work, etc. The energy-saving, environmentally friendly, low-emission engine is used for the trolley to move around, and the braking system uses wet dual-circuit emergency braking; the parking brake adopts spring braking and hydraulic release, which makes the work safer. Adopt articulated frame, flexible steering; hydraulic drilling system has three-level anti-jamming, anti-air drilling and other functions, which can effectively improve drilling efficiency and reduce drilling tool loss; electrical system is designed with ground fault protection, phase sequence protection, oil return Complete protection mechanisms such as blockage alarm, motor thermistor protection, overload protection, etc.; can be equipped with four different thrusters, covering the single drilling depth range of 3.3m~5.2m; the drill boom can be equipped with an extension section, the maximum operation The range can be extended from 90㎡ to 104㎡.
Main technical highlights of the product
Rock drill
The imported rock drill has the characteristics of super anti-bending ability, high drilling speed and low drilling tool loss, which effectively improves the adaptability of tunnel edge drilling.
thruster
Light aluminum alloy beam, high-efficiency bending, torsion and fatigue resistance, long service life. The unique single-layer arrangement of the hose reel, combined with the reliable pipe clamp structure, has good hose tensioning performance, effectively prolonging the life of the hose and reducing the maintenance intensity;
Drill boom
The drill arm is kept in parallel in all directions, and the positioning is fast and accurate; the square structure has high strength and good shock absorption performance;
Drilling system
It has the functions of anti-jamming, anti-running and automatic retraction, which can effectively improve the drilling efficiency and reduce the loss of drilling tools;
Hydraulic system
The auxiliary action of the outrigger and ceiling light adopts the electronic control design, the pipeline is simplified, and the maintenance is easy;
Electrical System
The electrical components of international famous brands such as Schneider and Siemens are selected, which have high reliability and long service life; they are equipped with protection and alarm functions such as ground fault protection, phase sequence protection, motor overload protection and engine fault alarm.
