The Belarusian innovative enterprise Rudgormash LLC is located in Soligorsk, a city of Belarusian miners. Its main specialization is the design, manufacture, installation, adjustment, maintenance, diagnosis and repair of technical devices used at hazardous production facilities. A huge plus for the enterprise is the fact that almost all manufactured equipment, embodying all the latest Belarusian and international scientific and technical achievements, in the process of its development and production can be immediately tested in the most difficult working conditions at the mines of Belaruskali OJSC. All this, combined with the vast practical experience of the company's employees, allows us to constantly introduce all new innovative developments into production.
The core of the company is highly qualified specialists, and the accumulated experience and scientific base, as well as close cooperation with research and design organizations, allows the company to solve complex and energy-intensive tasks in the development and production of equipment according to the needs of consumers around the world.
One of the new innovative developments of the enterprise is the self-propelled mine car 10VS-22M, designed for railless transportation of rock mass with a loosened density of 1.35-1.4 t/m3 in underground mines and mines hazardous for methane gas and coal dust, at an ambient temperature of + 5°С - +35°С in workings with a width of at least 3.0 m, a height of at least 2.4 m, as part of tunneling complexes together with combine harvesters, self-propelled cars and bunkers-loaders of various types.
In 2018, for the first time, pilot tests of self-propelled mine cars 10VS-22M, which currently have no analogues in the world in terms of their characteristics, were successfully carried out in the conditions of the mines of the Starobinsky deposit of Belaruskali OJSC. The new mining hero, born in Belarus, even among his brothers, the powerful and high-performance equipment of Rudgormash LLC, stands out not only for its greater power and load capacity, but also for many other qualities that are beneficial and useful for miners. What are the main advantages of self-propelled mine cars 10VS-22M?
The main advantages of the 10VS-22M car during long-term operation in difficult and dangerous conditions are:
- increased to 22.0 tons carrying capacity and, as a result, an increase in productivity;
- loading height (1150 mm) and adjustable unloading height (750-1400 mm), which allows joint use with all existing machines for loading and reloading rock mass: all models VS, BP, PPS.
- indicators of the braking distance of the car 10VS-22M (2.5m), angles of entry (front - 12°, rear - 15°), turning radius on the outer dimension 7800.0 mm, longitudinal radius of passability 3400.0 mm make it possible to safely use the machine in all types of existing workings again developed mines of the Nezhinsky section of the Starobinsky deposit of Belaruskali OJSC;
- the possibility of towing to the place of work by a universal towing device developed by Rudgormash LLC, which is a set of interchangeable devices for machines of the MD type.
The hard and coordinated work of the entire team allowed the enterprise to achieve such characteristics of its new innovative technology. At the same time, very important and useful design improvements have been implemented in all self-propelled mine cars manufactured by Rudgormash LLC. What exactly?
A microprocessor circuit for controlling the electrical equipment of a self-propelled car has been developed and implemented on existing samples, which has a number of significant advantages:
1.1 Ability to quickly change the functioning of the circuit without interfering with the electrical circuit diagram;
1.2 Possibility to provide visualization of equipment operation (measurement of current values of car speed, phase voltages);
1.3 Ability to provide visualization of faults;
1.4 Saving information about operation and malfunctions in non-volatile memory with the ability to view, transfer data;
1.5 Increasing safety in the operation of equipment due to the algorithm of operation, the possibility of self-testing and the application of the necessary protections:
1) zero protection;
2) against overload currents and short circuit currents;
3) from overheating of electric motors;
4) from unacceptable decrease in insulation;
5) from a break in the grounding conductor;
6) from incorrect alternation and phase failure of the supply network;
7) from any damage in the control circuit (short circuits and breaks); 8) from getting personnel under the action of dangerous voltages.
1.6 Improving the noise immunity of equipment under heavy operating conditions by expanding the range of supply voltages;
1.7 Expansion of measuring capabilities with display of current values of voltage, current, insulation resistance on the operator's console;
1.8. The presence of a 127V 50Hz outlet with a power of 4kW as part of a control station for connecting a vulcanizer or a portable drill;
1.9 Application of a soft start system for travel motors to improve smooth running and smooth out peak loads in the machine's transmission (increase the service life of mechanisms, reduce maintenance and repair costs) with the possibility of shutdown;
1.10 Possibility of using an electric drive with adjustable speed;
1.11 Possibility of equipping the wagon with a communication system with the mine dispatcher;
1.12 Possibility of installing a sensor measuring the mass of rock transported by the car.
2.1 The working pressure in the steering hydraulic system has been increased to 18.0 MPa: increasing the speed of the system and reducing the effort on the steering wheel; 2.2 The working pressure in the hydraulic system of the brakes has been increased to 12.0 MPa: an increase in the speed of the brake system, the implementation of a greater braking force in the working and parking brake mechanisms.
2.3 Installation of bridge lifting jacks: reduction of time for maintenance and repair of the car undercarriage.
3.1 The body of mass-produced wagons consists of three parts, which greatly facilitates the descent into the mine.
4.1 The use of disc-type parking brakes with the possibility of realizing a larger braking torque and simplified regulation.
5.1 Use of an adjustable steering column;
5.2 Use of adjustable seats. All these constructive improvements allowed the innovative Belarusian enterprise not only to increase the productivity, reliability and safety of the manufactured equipment, but also to make it even more convenient for those who have to work with it in difficult and dangerous conditions.
Thus, both mine and all other equipment produced by Rudgormash LLC can rightfully be called not only equipment for mines, but also equipment for miners. By purchasing powerful, comfortable and reliable machines from the Rudgormash company, you can be sure that Belarusian mining equipment will not let you down in any, even the most difficult operating conditions!
