Resumen:
Una empresa búlgara ofrece un martillo universal para partir rocas que tiene una masa total muy pequeña, inferior a 2.000 kg, con una parte de impacto de solo 700 kg y que golpea a una velocidad de hasta 22 m/s en cualquier ángulo del espacio. La alta velocidad de impacto se consigue con un motor de combustible sólido o líquido. Gracias a su masa pequeña, el martillo puede transportarse en cualquier vehículo de transporte y partir rocas en lugares de difícil acceso. Este martillo de impacto de alta velocidad estabiliza terrenos inestables, como loess y arcilla. La empresa busca compañías de la industria de la construcción para financiar y desarrollar los martillos.

Hammer for breaking rocks and stabilizing unstable soils
Summary:
A Bulgarian company offers a universal hammer for rock breaking (HRB) that has a very small total mass of less than 2000 kg, with an impact part of just 700 kg, which can hit at high speeds up to 22 m/s at any angle in space. High impact velocity is achieved with a solid or liquid jet engine. Due to its small mass the HRB can be transported by any transport machine and hit on rocks in difficult-to-reach places. HRB with high-speed impact can stabilize unstable soils, such as loess and clay.
Description:
High technology is available for high-speed rock breaking and stabilization of unstable soils. It is realized with a universal hammer for rock breaking (HRB), which can also be used to stabilize unstable soils. Explosive activities in quarries and opencast mines often result in large rock fragments that can not be transported or crushed by crushers. That´s why these rocks are detonating, which is slow, awkward and dangerous. To solve the problem, one-shot hydraulic hammers are available that break down the rocks with a dropping impact of up to 8350 kg.
These hammers used mechanical hand that rocks can reach up to 12 meters by the holder of hammers. Due to the free fall impact, these hammers can only strike vertically and at a very low speed - up to 4.85 m / s. Another disadvantage is that they make an indirect blow, and with a mediator - a separate wedge. For transportation they use transport equipment whose mass, in a chain variant, reaches 60000 kg.
Bulgarian company offers a universal hammer for rock breaking, that has a very small total mass of less than 2000kg, with an impact part of just 700kg, which can hit at high speeds up to 22 m/s at any angle in space. High impact velocity is achieved with a solid or liquid jet engine. Due to its small mass the HRB can be transported by any transport machine and hit on rocks in difficult-to-reach places. HRB with high-speed impact can stabilize unstable soils, such as loss and clay.
A physical prototype of HRB is created, which has a total mass of 1700 kg, and the impact part has a mass of 700 kg. The solid-fuel reactive engine that powers the impact piece has an initial mass of 30 kg. For the tests are used rock blocks of mineral andesite, which at strength is equivalent to granite. Successful tests have been carried out using two types of impact punches - wedge and conus at a speed of over 21 m / s. The tested HRB has complete engineering and technological documentation. The Reactive Engine has been tested on a stand to produce a variety of effort - from 1000 to 3000 kg. There is no problem to make demonstrations, to run in regular production and to seek market in Bulgaria and abroad.
Advantages and Innovations:
The product is suitable for for large scale rock fragments and for breaking rocks in difficult to reach places known to us, as well as stabilizing unstable soils. Advantages of the proposed hammer:
- A very high impact energy (for comparison, the impact energy responds to a hit of a hydraulic hammer with an equivalent mass of 12000kg, that is, this hammer is the most powerful hammer to break in the world!),
- High speed punching,
- Direct strike,
- Combination stroke (this is only possible with the propulsion system offered),
- Possibility to strike at any angle in the space (this is only possible with the actuator used by the offered technology);
- Ability to access hammer to the most inaccessible for the available equipment due to its small total mass,
- Easy service and hammer operation (due to its simple device),
- Working with the hammer is much safer than blasting,
- Low cost of the single hit.
The innovation proposed is a worldwide innovation. For the first time, a hammer is used, whose impact is driven by a solid or liquid jet engine. A high-speed impact is applied, which is very effective for breaking rock and stabilizing unstable soils. Because of its small mass, the offered HRB is very mobile. It can be transported and operated with a truck, concrete pump and helicopter.
