GY-80 Crawler Type Anchor Drilling Rig
Feature:
1. Anchoring can be suitable for the construction methods of drill pipe drilling, casing drilling, and composite drilling of drill pipe and casing. Rotary jets can be suitable for single, double, and triple rotary jetting.
2. Adopting full hydraulic power head drive with step-less variable speed, high drilling efficiency, and low labor intensity.
3. The power head adopts hydraulic variable speed and has high and low gears to meet the requirements of various formations and different drilling processes, adds hydraulic rear top hammer type impact function, and realizes the integration of impact and rotary structure. This not only enables the drilling rig to quickly drill into general rock formations but also achieves fast drilling in sand and gravel layers as well as cobble layers while ensuring a significant reduction in the number of accessories, reliable quality, and easy maintenance.
4. Reverse drilling device: When sticking occurs during drilling, the drill pipe can be quickly removed by striking the drill pipe with the reverse drilling device.
5. Frequency regulation: Hydraulic impact drill cylinder with manual frequency regulation device, can be adjusted according to different geological conditions.
6. Direct-acting load feedback fine-tuning variable hydraulic system, power varies with load, high efficiency, low energy consumption.
The main components of the hydraulic system of the drilling rig adopt famous brands, with a stable and reliable system and long service life.
7. The drilling rig has a self-propelled crawler function, which makes it easy and fast to move the equipment.
8. Equipped with a rotary, the hole position can be turned to the side of the track to work when needed.
9. Compact structure, centralized operation, convenient and safe.
Application:
GY-80 crawler-type fully hydraulic engineering drilling rig is used for foundation reinforcement, water isolation, leakage plugging, soft foundation treatment, geological disaster management, and anchoring for controlling building displacement in various industrial and civil buildings such as railroads, highways, bridges, road foundations, and dam foundations. It can be used for rotary drilling with common alloy drill bits and other drilling tools; it can be used for impact rotary drilling in rock layers and high-speed hole formation with conventional ball tooth bits; it can be used for drilling holes with casing in unstable strata such as pebble layers and other unstable strata with follow-the-pipe drilling tools; it can be used for hydraulic impact to meet the requirements of impact rock-breaking hole formation, liquid discharge, underground mini-pile, anchor rod, and anchor cable, geological exploration, geothermal hole formation, foundation reinforcement, and slope support. The construction requirements of infrastructure construction, such as the choice of a rotary jet module with rotary jet function (swing jet, fixed jet). It can also carry out the construction of over-the-tunnel pipe shed support and geological pre-prospecting.
