Development history of rotary drilling rig

Market background

Ten years ago, the domestic market share of domestic rotary drilling rigs was less than 5%, and the market was monopolized by foreign brands. Nowadays, the domestically made rotary drilling rig represented by this company has achieved a gorgeous "counterattack", which not only won the domestic market but also opened an exciting prelude to entering the foreign market. Nowadays, in China, it is hard to see imported rotary drilling rigs, but if you go abroad, it is not difficult for you to find this brand-YG Machinery. At present, YG's rotary drilling rigs have a high domestic market share, constantly setting new records one after another. For example, the domestically-made rotary drilling rig with the largest tonnage exported to Cambodia is sold to Cambodia, demonstrating the strength of a major country's heavy equipment. And our market share in Papua New Guinea ranks first. The two-wheel slot milling machine developed on the basis of the accumulation of rotary drilling rig technology has shaken the monopoly of foreign brands.  

Introduction of Rotary Drilling Rig

A rotary drilling rig is a construction machine suitable for hole-forming operations in building foundation engineering. It can be widely used in municipal construction, highway bridges, high-rise buildings, and other foundation construction projects. It is an indispensable machine for high-speed rail, highway, and bridge construction. As early as 1998, YG Group took aim at this kind of infrastructure construction equipment, and it was also the first domestic manufacturer to realize independent research and development and production of rotary drilling rigs. At that time, rotary drilling rigs belonged to a new category of construction machinery, the market was monopolized by foreign brands, and also belonged to YG's "marginal products."

After the establishment of YG Machinery, it adhered to the ideal and belief of "promoting the continuous upgrading of China's basic construction machinery industry". Comparing with international benchmarks, we will continue to innovate and make breakthroughs and promote products to move towards mid-to-high-end products to meet the needs of domestic and foreign users. Today, YG rotary drilling rigs are exported to more than 20 countries and regions around the world. YG rotary drilling rigs also have a huge market share in the Turkish market, which is known for being picky.

Advantages of hydraulic down-the-hole drilling rigs

 What are the advantages of hydraulic down-the-hole drilling rigs?

Down-the-hole drilling rigs are widely used in many geological explorations. The drilling tool can be directly drilled into the ground to obtain relevant geological data. In many medium and large construction environments, if the blasting method is used, there is not only a large risk factor, but also the corresponding construction effect cannot be achieved. Therefore, it is not recommended to use the construction method. So what are the performance characteristics of down-the-hole drilling rigs that have been unanimously recognized by everyone? Let the editor lead everyone to understand it together!

In addition to the pursuit and products of various rock drilling equipment in engineering and mining, some projects also require simple, reliable, flexible and economical small products. YG-150 is a new type of open-air down-the-hole drilling rig improved on the basis of summarizing customer needs and previous product experience. According to the sleeve power standard, the drilling rig is divided into two types: B-type two-cylinder Yuchai 2115 and D-type electric 22kw. This standard strengthens the walking motor, gearbox structure and pitching boom to make the climbing ability stronger and the quality more reliable. This machine is equipped with a simple disassembly and assembly protective cover, which can prevent dust and falling rocks, improve performance, and make the machine more beautiful. Next, the editor will introduce to you what are the advantages of hydraulic down-the-hole drilling rigs.

The advantages and disadvantages of integral down-the-hole hammer drilling are that the pneumatic down-the-hole hammer can quickly drill in gravel and hard rock formations, and the 600 mm diameter down-the-hole hammer can drill 20 meters in gravel and weathered rock formations. Drilling 12 meters into the rock formation, the following casing can overcome the problem of a hole wall collapse.

Product advantages

　　1. The high-pressure pump, the two-speed travel plunger motor, and the heavy-duty crawler make the product have extraordinary off-road capabilities, and at the same time improve the reliability of the product.

　　2. Drill boom: While satisfying the drilling torque, it adopts a new type of power rotating head. The triangular guide rail can improve the wear resistance and facilitate the adjustment of the slider gap. The optimized structure reduces the weight and makes the boom more flexible. At the same time, it also meets the needs of some families to drill 3m holes, and can directly drill horizontal holes forward.

　　3. The operating room has low centralized control, reasonable location, and convenient operation; the dual-position walking operation platform makes the displacement and long-distance walking vision better and more convenient.

4. The excellent dry dust removal system meets the requirements of green mine construction.

5. The YG DTH drilling machine has a stable structure and a low center of gravity. Affected by the construction environment, even under severe environmental conditions, there will be no accidents such as tilt during operation, and it is durable.

　　 The above is the whole content of "What are the advantages of hydraulic down-the-hole drilling rigs", I hope everyone can understand.

How to choose a right drilling rig?

 

How to choose a drilling rig?

You need drilling equipment for various purposes. For example, drilling a well to obtain natural resources (water, oil, geothermal energy, etc.) to build a foundation, drill holes in a mine, and take samples from the ground.

 

It is necessary to determine the purpose of the drilling rig and what kind of terrain it is mainly operated on. Depending on the terrain, you can choose different types of drilling rigs: rotary drilling rigs, percussion drilling rigs, down-the-hole drilling rigs, top hammer drilling rigs (with high hammers), etc.

 

In order to make the best choice, it is important to determine whether the rig is used for core business or occasional use, especially if you are using the latest technology, or a rig that has been available for decades.

 

Security, reliability, and ease of use are also important factors that need to be considered, and there is a direct connection between them. According to the drill machine manufacturer's recommendations, the use of reliable and easy-to-operate drilling rigs can improve user safety.

 

It is also very important to define the type of movement required by the rig. There are crawler-type automatic drilling rigs and truck-mounted or trailer-mounted drilling rigs, which need to be powered by generators or trucks that carry them.

 

Once the type of rig required is determined, the required rig size can be calculated based on the diameter and depth of the hole.

When do you need to drill rig?

Drilling is required in many jobs, such as:

Drilling: used to obtain groundwater or oil.

Geothermal drilling: obtain and extract geothermal energy.

Pile-driving rigs that support buildings on unstable ground: up to 2000 mm in diameter and 70 meters in depth.

Micro pile drilling rigs, especially for drilling holes for reinforcement of existing structures: diameter between 150 and 200 mm, depth within 30 meters.

Blasthole drilling rig in the quarry.

The continuous rotary uses drill cuttings driven by the rotary drill machine to maintain the borehole wall.

Drilling is usually done vertically, but it can also be horizontal or directional, for example for anchoring.

Which type of drilling rig should I choose?

There are two main types of drilling rigs: automatic crawler type and truck-mounted or trailer type.

If you need to move at a low speed on uneven areas or very soft ground, you can choose a crawler drill. The stability of the rig depends on the surface area of the track. Therefore, the wider the crawler, the more stable the drilling rig. But when the track is too wide, when moving, especially when turning, it tends to wear faster and damage the ground. The crawler drilling rig has a travel speed of about 4km/h, so it is more suitable for operations that require little travel.

Truck-mounted or trailer-mounted drilling rigs are not autonomous in mobility or energy. These energy sources may come from transport trucks or independent generators. However, this type of drilling rig is much lower in cost than crawler drilling rigs. Click here to know more.
