Definitions

  • the present invention relates to a test equipment for mining anchors which is used to test the different designs of mining anchors that are installed in the roofs, shoulders and side walls of the underground tunnels of the industry.
  • the test equipment for mining anchors is used to measure the resistance to breakage of mining anchors, for which a study was initially developed to know what the resistance an average mining anchor should have in order to validate that it will be effective at the moment of being installed in the roofs, shoulders and lateral walls of the underground tunnels of the industry and that will reinforce the rock premise so that the rock does not fall and does not put at risk the health of the personnel entering the mine.
  • test equipment for mining anchors which are cylindrical and are used to measure the strength of the anchors so that they can be installed by meeting the average load pattern and breaking strength, these are similarly formed by a barrel and two wedges or jaws with which the mining anchor is fastened to perform the test.
  • TECHNICAL PROBLEM TO BE SOLVED are similarly formed by a barrel and two wedges or jaws with which the mining anchor is fastened to perform the test.
  • the problem presented by the previous test equipment is that its design is a round barrel and round wedges or jaws that are introduced into the barrel, so that when testing a mining anchor, the jaws were trapped inside from the barrel, this causes a lot of work to be done to the test equipment so that the jaws can be extracted again for the next test, this causes a test process of a longer time considered to the new equipment design test presented in the invention, the new barrel and wedges or jaws model, does not cause wedges jams, so it is very easy to extract the jaws after having performed the test in some mining anchor, this causes less effort! operator of the test equipment for the extraction of the jaws and less time to place the next test.
  • the test equipment for mining anchors is formed by a barrel which is composed of four 1/2 "(12.7 mm) thick steel plate walls which are joined by welding on the inside and outside to Resist the efforts, these plates handle an opening at an angle of 2 °, the total height of the barrel is 150 mm, this has a circular frontal plate of 93 mm which has a perforation to the center which serves to insert and travel the mining anchor once the wedges or jaws are placed, the jaws of the mining anchor test equipment are made of high strength steel, since these are made a thread in the part of the face that adheres to the mining anchor at the time of the test, the thread is in position opposite to the advance of the anchor when performing the test in such a way that it is held by the jaw teeth to exert the necessary load to measure the strength of the mining anchor.

  • 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.
  • 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.
  • 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

Abstract

L'invention concerne du matériel d'essai pour ancrages miniers à installer dans des tunnels de l'industrie minière formés par deux corps, le premier corps étant composé de quatre parois d'acier et d'une plaque circulaire avec une perforation centrale soudée à ceux-ci au niveau de leur base, le second corps étant constitué de deux cales à insérer dans le premier corps qui fixent l'ancrage minier au moment de l'essai.
