UGB-50M - drilling “grandmother”

The first Russian production of drilling tools and drilling rigs was opened at the base. For more than 100 years, the plant has produced and continues to produce drilling tools for drilling wells for various purposes: geological exploration, seismic exploration, water wells and others. Every year, developers offer new solutions, improve drilling rig production technology, and produce modern drilling rigs and tools.

In the post-war years, the plant mastered the production of multi-purpose drilling rigs, which, among other things, were used to drill water wells. Until the end of the 80s of the last century, serial production of UGB-50 M drilling rigs was carried out, which replaced the UGB-1VS rigs, and then the PBU-1 and PBU-2 drilling rigs.

However, the heads of drilling companies are in no hurry to abandon the reliable UGB-50M drilling rigs, and here's why:

1. The transverse arrangement of the winch is the best option; during the modernization they came to a longitudinal arrangement (UGB-1VS), and now they have returned to the transverse arrangement (PBU).
2. The transmission of rotational force from the gearbox to the UGB-50M winch occurs through a gear, and on UGB-1VS, PBU, through a chain drive, which often requires replacement or repair.
3. UGB-50M has an “eternal” mechanical drive, which is often superior in reliability to the capricious hydraulic drive of PBU-2, especially in cold weather.
4. On the UGB 1-VS, to increase the speed, they began to install accelerators, thereby complicating the hydraulics; on the PBU-2 there is no accelerator, just like on the UGB-50.

Among the shortcomings, one can note only the short stroke of the rotator (1.5 m) versus 4 m (UGB-1VS, PBU-2), but you can get used to it.

The UGB 50 drilling rig is multifunctional, mobile and reliable, and spare parts for it can be found almost everywhere due to its long-term production, high prevalence and extreme wear resistance.

Due to the reliability of the UGB-50M rig, drillers nicknamed it the “drilling grandma.” In the automotive industry, it can be compared to the GAZ-66 army vehicle, a vehicle that has no competitors on off-road terrain. By the way, the UGB-50M installation was mainly mounted on the GAZ-66 chassis.

Chassis

The drilling rig can operate both on a chassis and without it. One of the advantages of UBG-50 is its low weight; the lightweight design weighs approximately 300 kg.

A significant part of the drilling rigs were mounted on a GAZ-66 chassis, and a set of drilling tools was supposed to be transported by a special 2PN2 trailer.

There are also modifications on the ZIL chassis.

technical specifications, design, photos and videos

The first Russian drilling rigs with all the corresponding tools, as well as drilling and crane machines, began to be produced at the Shchigrovsky iron foundry and mechanical production plant, which was reorganized into a production association. These plants have created hundreds of pieces of various geological, seismic, downhole and other drilling equipment. His brainchild is the UGB-50 drilling rig, which is still in demand in earthworks in the Russian Federation and abroad.

Drilling rig UGB-50 - general information

The UGB-50 drilling rig is specially designed for drilling hydrogeological and engineering-geological water wells with a possible penetration depth of up to 75 meters. The installation is made dismountable, and its assembly on site is not difficult and takes a minimum of time - only about an hour. In addition, the ease of use of UGB-50 is made up of the following parameters and elements:

• The soil categories used are from I to IV, that is, the most common in water supply installations. The operation of the drilling apparatus is completely mechanized with the ability to be controlled and maintained by only one operator.
• The machine performs a full range of drilling operations to install a water well, without requiring the participation of additional mechanisms and tools.
• For drilling, several methods are used (rotary and impact-rope) with the installation of working tools: auger, impact, core.
• Both operation and maintenance of the machine are quite simple and do not require special conditions.

And also - the time-tested reliability of the structure and all components, which allows minimizing maintenance and the cost of ongoing repairs.

IMPORTANT! An important feature of the UGB-50 mobile drilling rig is its low weight - only about 300 kg. The lightness of the overall design allows for convenient installation on wheeled vehicles and transportation over any distance.

Device

Let's look at the main components and design of the URB-50 drilling rig

Main nodes

Structurally, the UGB-50 drilling apparatus consists of the following parts:

• Collapsible frame;
• Gear motor;
• A set of different types of drills;
• Drill rod store;
• Lifting winch;
• Electrical systems with reverse reverse.

ATTENTION! To operate, you will also need a motor pump, which is usually not included in the factory kit. It will have to be purchased additionally.

Design

For the drilling unit to operate, all assembly requirements must be met, which includes the following points:

• UGB-50 can operate both on a chassis and without it. Most often it is installed on the base of a GAZ-66 vehicle, which gives it the ability to work in off-road conditions and limited areas, although there are options for installation on other vehicles, for example ZIL.
• All systems are installed on a common frame, which includes a D-65LS radiator engine with a gearbox, as well as a mast along which the hydraulic cylinders for feeding the working tool move. The entire impact mechanism and lifting winch are installed here.
• The open front side of the drilling mast is equipped with two rollers - a working one and an additional one. It is put into lifting motion by means of hydraulic jacks, and lowered by disconnecting the vertical shaft from the gearbox.
• When the device is activated, the rotator receives three forward and the same number of reverse speeds. An appropriate chuck for installing the necessary tool is attached to its spindle: a hexagon with pin fasteners for an auger or a drive rod for core drilling.
• The design of the impact mechanism includes a crank, a balancer and spring shock absorbers.
• The movement of the planetary type winch is controlled by two band brakes. Its drum is engaged through a gear clutch, and three speeds are transmitted to it from the gearbox.

IMPORTANT! Sometimes the disadvantage of UGB-50 drills is the small size of the hammer. However, this fact allows you to create the most accurate holes of small diameters using the installation.

Specifications

The technical characteristics of the UGB-50 drilling rig are reflected in the following table:

Modifications

The developers of UGB-50 units improve its design every year, offering new solutions, technologies and control features. But the only modification of this particular basic installation is the UGB-50M device, which has several important differences from it:

• Installation of a more compact diesel engine of the D48L brand while maintaining the rated power of the main drive.
• Reducing the total weight of the device, which made it even more mobile.
• Increasing the possible drilling depth, which made it possible to drill wells in deep water formations - up to 100 meters.

What the basic and modification models have in common are the strength of the nodes and undeniable reliability indicators:

• The presence of a mechanical drive, which is superior in durability to a hydraulic one.
• Convenient transverse location of the lifting winch.
• Simple transmission of motion from the gearbox to the lifting winch via a gear, as opposed to a quick-breaking chain drive.
• No accelerators that complicate the work of hydraulics, etc.

After the first releases of UGB-50 and UGB-50M, many new models appeared, but even now drilling companies are in no hurry to replace them with new products. The convenience and reliability of these “indestructible” units are complemented by a number of innovations.

Satellite system "GLONASS" on drilling rigs UGB-743-200

Drilling rigs UGB-743-200 on the chassis of the TGM tracked all-terrain vehicle have been in operation since May 2014.

UGB drilling rigs are equipped with: — AK-9/10 compressor; — a drilling drawworks with free discharge with a lifting capacity of 3000 kgf; - block of pipe holders. The feed stroke of the unit's rotator is 5.2 m, which allows the use of TBSU drill pipes with a length of 4.7 m. During operation, UGB drilling rigs were used in engineering geological surveys in various regions of Russia. The drilling technologies used at UGB-743-200 are rotary core drilling with a diameter of 127 mm to a depth of 10 to 17 m in rocks of categories I-VII in terms of drillability. When using UGB drilling rigs, the average productivity of geotechnical teams increased by 12%. During the entire period of operation of the UGB-743-200 drilling rigs, no downtime of geological crews due to failure of the drilling rigs was noted, with the exception of the TGM all-terrain vehicle, while during a relatively short period of operation, both advantages and wishes for improving the UGB rigs were identified.

Advantages of UGB-743-200:

— convenient, functional drilling rig control panel; — convenient hydraulic pipe holder system; — high speed of hoisting operations; — easy and predictable to operate.

In general, the operation period of May-July 2014, the operation of the UGB-743-200 drilling rigs on the TGM tracked all-terrain vehicle chassis is assessed positively. To objectively assess the performance of drilling rigs, operating experience in the autumn-winter period is required.

Horizontal drilling rig

The horizontal drilling installation (puncture, punching) is intended for the construction of underground passages of pipelines, communication lines or other communications under highways, railways or structures in soils of class 2-4 according to GOST 25100 (except rocky, semi-rocky and sand), with a skeleton density of no more than 2g /cm3 without stopping traffic on roads or demolishing (bypassing) structures, that is, using trenchless technology. The UGB-17 installation can operate both on the principle of drilling a well and on the principle of puncture (pushing). In the first case, the drilling head goes in front of the cartridge being inserted; in the second case, the drilling head is located inside the pushing cartridge to drill out the soil that gets inside the cartridge.

The screw conveyor is assembled from separate sections in order to achieve the required length. The transition can be constructed to its full length, and in cramped conditions, by gradually lengthening the cartridge and screw conveyor.

The installation units are mounted on a common frame mounted along the transition axis. Its own diesel engine is used as the power unit.

The completeness of installation of screws with the required diameters and required lengths is agreed upon additionally. Replacement equipment for laying a cartridge of a specific diameter with a length of 60 m includes the following components:

• drilling head - 1 pc.;
• main augers (length 6 m) - 10 pcs.;
• adapter augers (length 3.6 m, 3 m, 2.4 m, 1.8 m) – 1 pc. each length;
• connecting elements for augers - 15 sets;
• transition elements (saddles) for mounting the UGB on the cartridge pipe - 1 set.

By special order, screws for various purposes can be designed and manufactured to the diameters required by the Customer from a minimum diameter of 159 mm to a maximum diameter of 1720 mm.
The operating principle of the installation is based on mechanical drilling. The main working part of the installation is the drilling (milling) head. When drilling, the cartridge pipe being laid is simultaneously fed into the bottom hole (well).

The soil resulting from the development is constantly removed by a screw conveyor.

The drilling mechanism and chuck pipe are fed by a mechanical winch. The maximum single technological passage length (without reinstalling the machine on the chuck or reinstalling the anchor or changing the rope insert) is 30 m (when the winch is operating through a standard pulley).
