The test equipment for mining anchor (Figure 1) is formed by two parts, the first is a barrel (Figure 2 and Figure 3), which is formed by 4 plates joined by welding, which have a thickness of 1 / 2 "(12.7 mm), these are welded by the internal part and the external part in such a way that a resistant barrel is generated that does not break when the force is exerted to test the mining anchors, its union forms an angle opening towards the back of 12 ° where the wedges or jaws are inserted, the steel barrel has a circular plate (1: Figure 2) of 1/2 "(2.7 mm) thick front steel which counts with a hole in the center (2: Figure 2) made in 1 "(25.4 mm) where the mining anchor passes when it is inserted in the test equipment.
Las cuñas o mordazas (Figura 4 y Figura 5) que forman el segundo cuerpo del equipo de prueba para anclas mineras son dos piezas elaboradas de acero de alta resistencia, las cuales se insertan adheridas al ancla minera dentro del barril para llevar a cabo el ensaye, estas tienen un corte circular por la parte interna (3 : Figura 4), donde es insertada el ancla minera, y a la vez tienen rosca afilada en esta curvatura de tal manera que al ser colocadas en el ancla minera y ambas en el barril la aprisionen para que no recorra y permita realizar correctamente el ensaye. The wedges or jaws (Figure 4 and Figure 5) that form the second body of the test equipment for mining anchors are two pieces made of high strength steel, which are inserted adhered to the mining anchor inside the barrel to carry out the test , these have a circular cut through the internal part (3: Figure 4), where the mining anchor is inserted, and at the same time they have a sharp thread in this curvature so that when they are placed in the mining anchor and both in the barrel the imprison so that it does not travel and allow the test to be carried out correctly.
MEJOR MANERA DE LLEVAR A CABO LA INVENCIÓN BETTER WAY TO CARRY OUT THE INVENTION
Se tiene una ancla minera a la cual ensayar para conocer su resistencia a la ruptura mediante el equipo de prueba para anclas mineras (Figura 1 ), el ancla tiene un extremo con argolla o algún implemento que ejerce la resistencia cual retiene la roca en mina, simulando que el esfuerzo lo genera la roca, pero mediante un pisto hidráulico que es colocado por el extremo posterior y hasta
topar en la argolla o implemento de resistencia de la parte frontal del ancla minera, posteriormente es insertado el barril (Figura 2 y Figura 3) del equipo de prueba por la parte posterior del ancla y colocado hasta juntarlo con el pistón hidráulico que fue instalado inicialmente, de tal manera que la placa circular frontal del equipo de prueba para anclas mineras es la que se junta al pistón hidráulico, en seguida son colocadas las cuñas o mordazas (Figura 4 y Figura 5) a los costados del ancla minera y dentro del barril, una mordaza en cada costado y estas son colocadas a la misma altura o nivel, de manera que el siguiente paso después de tenerlas sobre puestas será golpear mediante un martillo cada una hasta que estas atrapen con fuerza el ancla para que no recorra en el barril sin ejercer fuerza. There is a mining anchor to test for its resistance to breaking through the test equipment for mining anchors (Figure 1), the anchor has an end with a ring or some implement that exerts the resistance which retains the rock in the mine, simulating that the effort is generated by the rock, but by means of a hydraulic gun that is placed at the rear end and even bump into the ring or implement of resistance of the front part of the mining anchor, then the barrel (Figure 2 and Figure 3) of the test equipment is inserted by the back of the anchor and placed until it is joined with the hydraulic piston that was initially installed , such that the front circular plate of the test equipment for mining anchors is the one that joins the hydraulic piston, then the wedges or jaws (Figure 4 and Figure 5) are placed on the sides of the mining anchor and inside the barrel , a gag on each side and these are placed at the same height or level, so that the next step after having them on top will be hitting with a hammer each until they catch the anchor hard so that it does not travel in the barrel without exerting force
Una vez colocados los implementos que forman parte del ensaye que son: pistón hidráulico, barril de prueba (Figura 2 y Figura 3) y dos cuñas o mordazas (Figura 4 y Figura 5) para la prueba, se procede a realizar el ensayo, de tal manera que se le aplicara carga en el pistón hidráulico para intentar romper el ancla y así conocer la magnitud de su resistencia, misma que es comparada con los patrones promedios de masa de los bloques de macizo rocoso de las obras mineras, ya que se puede decir que los bloques de roca que se forman en los túneles pueden llegar a tener una masa rocosa de 10 toneladas aproximadamente, y la resistencia promedio de las anclas varia, para las anclas de 5/8" de diámetro es requerida una capacidad de carga de 15 toneladas y para un ancla de 3/4" de diámetro es requerida una capacidad de carga de 18 toneladas. Esto con la finalidad de poder decidir la calidad de las anclas para que sean eficaces al momento de su instalación en los túneles subterráneos de la industria minera.
Once the implements that are part of the test are placed: hydraulic piston, test barrel (Figure 2 and Figure 3) and two wedges or jaws (Figure 4 and Figure 5) for the test, the test is carried out, of such that a load will be applied to the hydraulic piston to try to break the anchor and thus know the magnitude of its resistance, which is compared to the average mass patterns of the rock mass blocks of mining works, since it can be say that the rock blocks that form in the tunnels can have a rock mass of approximately 10 tons, and the average resistance of the anchors varies, for the anchors of 5/8 "in diameter a load capacity of 15 tons and for a 3/4 "diameter anchor a load capacity of 18 tons is required. This with the purpose of being able to decide the quality of the anchors so that they are effective at the time of their installation in the underground tunnels of the mining industry.
