Diamond bit drilling performance testboard device

Abstract

The invention discloses a diamond bit drilling performance testboard device, including a pedestal and a workbench arranged on the pedestal and capable of moving forwards, backwards, leftwards and rightwards. Stone is clamped on the workbench, a drilling machine which drills the stone through a drill stem is arranged above the stone, and the drilling machine is mounted on a portal frame or suspension arranged based on the pedestal. The testboard device also includes a control device which controls movement of the workbench, controls rotating speed of the drill stem and controls the drilling range and drilling force of the drill stem, and the control device tests the drilling efficiency and drilling life of the drill stem by calculating feed in unit time and displays the drilling efficiency and drilling life. The diamond bit drilling performance testboard device provided by the invention is simple to operate and convenient to test, can safely and efficiently test the drilling efficiency and life of a diamond bit, and is very convenient to carry out an experiment of safety detection of the drill bit.

Description

technical field [0001] The invention relates to a diamond bit performance testing technology, in particular to a diamond bit drilling performance testing platform device, which is suitable for testing the diamond bit drilling efficiency, drilling life and drilling safety. Background technique [0002] Diamond bits have been manufactured in China for more than half a century. Over the past 50 years, my country's diamond bit industry has grown from scratch, from weak to strong, and has played a huge role in promoting mineral resource exploration and geological development. [0003] Diamond drilling is the most basic and essential means of solving mineral resources. It is a job of "seeing the rice in the sand". Only geological drilling can accurately explain the actual situation of the underground. Accelerating the development of diamond drill bits and expanding new areas of application of diamond drill bits are of positive significance to the continuous optimization and upgrad...

AI Technical Summary

Problems solved by technology

[0004] Although after 50 years of development, diamond drill bits have made great progress in terms of formula design and structure optimization, their production methods are still decades ago, especially for the drilling performance and safety testing of drill bit products. It is all based on experience, without effective testing standards and testing methods, which will easily lead to problems such as poor applicability and unstable drilling performance when the drill is used on site, and it is also very easy to cause drill bit safety problems such as drill teeth falling off and collapse, thus delaying The drilling process is delayed, the drilling cost is increased, and unnecessary losses are caused

[0005] After the existing diamond drill bit is manufactured, it is generally drilled directly at the drilling site, and the actual drilling results are used to feed back and guide the design of the drill bit. The experimental cycle is long, there are many uncertain influencing factors, and the experimental cost is relatively high.
