Description

Technical Field

[0001] The invention belongs to the technical field of diamond drill bit strength testing, in particular to a diamond drill bit strength digital simulation testing device. Background Art

[0002] The drill bit with cutting edge is called diamond drill bit. This drill bit is an integrated drill bit. The whole drill bit has no moving parts and has a relatively simple structure. It has high strength, high wear resistance and impact resistance. Field use has proved that when drilling in soft to medium hard formations, diamond drill bits have the advantages of fast speed, high footage, long life, stable operation, few downhole accidents and good wellbore quality. Diamond drill bits not only have a long service life, but can also be reused. The diamond drill bits returned to the factory for repair have the same effect as the diamond drill bits leaving the factory, which can save a lot of drilling costs.

[0003] However, the hardness of diamond drill bits on the market needs to be tested before leaving the factory to ensure the product quality of diamond drill bits. Usually, the diamond drill bits are installed on the test equipment, pressure is applied to the diamond drill bits, and the changes in the diamond drill bits and pressure are recorded.

[0004] When using existing testing equipment, the diamond drill bit needs to be fixed to the testing equipment, usually by manual fixing, which is time-consuming and labor-intensive. The staff needs to adjust the fixing mechanism in the testing equipment, which increases the workload of the staff and is not convenient for large-scale use of the testing equipment.

[0005] At the same time, when the test equipment is in use, when the pressure applied by the test equipment to the diamond drill bit reaches a critical value, the diamond drill bit will crack under the higher pressure, causing the diamond drill bit debris to splash, causing harm to the staff and reducing the safety factor of the test equipment.

[0030] The pressure rod 3 will drive the diamond drill bit to move downward, so that the diamond drill bit contacts with the pressure detection plate 10 and squeezes the pressure detection plate 10. At this time, the pressure detection plate 10 will push the piston plate 9 to move downward along the inner wall of the groove 4, and then the piston plate 9 will squeeze the gas spring 5 and compress the gas in the groove 4, so that the gas inside the groove 4 enters the inner side of the slide groove 7 under the connection effect of the through groove 6, and then pushes the protective cover 8 to move upward. At this moment, the pressure detection plate 10 will be squeezed with the diamond drill bit under the limiting effect of the groove 4, so as to test the hardness of the diamond drill bit, and transmit it to the computer through the internal sensor to record the data.

[0031] Embodiment 2, by Figure 1-6 It is given that the inner wall of the pressure rod 3 is provided with a connecting groove 11, and the inner wall of the pressure rod 3 is movably connected with a trigger mechanism 12, and the trigger mechanism 12 includes a trigger groove 121, an electrical contact 122, an extrusion block 123 and a conductive block 124. The inner wall of the pressure rod 3 is provided with a trigger groove 121, and the inner wall of the trigger groove 121 is fixedly connected with the electrical contact 122, and the size of the electrical contact 122 is adapted to the size of the conductive block 124, and the electrical contact 122 is electrically connected to an external power supply. The inner wall of the trigger groove 121 is elastically connected with the extrusion block 123, and the structure of the extrusion block 123 is a circular ring structure. The extrusion block 123 is used to drive the movement of the conductive block 124, and the inner side of the extrusion block 123 is fixedly connected with the conductive block 124.

[0033] By pressing the diamond drill bit into the inner side of the connecting groove 11, the squeezing block 123 in the trigger mechanism 12 is squeezed into the inner side of the trigger groove 121 and brought to the conductive block 124 to move upward until the conductive block 124 is engaged with the electrical contact 122. At this moment, the squeezing block 123 no longer moves, and the electromagnet 14 electrically connected to the conductive block 124 is magnetic. Since the magnetism of the opposite surfaces of the electromagnet 14 and the magnetic plate 16 is the same, the electromagnet 14 repels the magnetic plate 16, so that the pressing plate 15 moves inward along the inner wall of the accommodating groove 13 under the action of the repulsive force, so that the pressing plate 15 clamps the diamond drill bit.

[0034] Working principle: When the test equipment is used, first install the diamond drill bit to be tested on the pressure rod 3, and then press the diamond drill bit into the inner side of the connecting groove 11. At this time, the diamond drill bit will move up along the inner wall of the connecting groove 11 and squeeze the trigger mechanism 12. At this time, the squeezing block 123 in the trigger mechanism 12 enters the inner side of the trigger groove 121 under the squeezing force, and brings the conductive block 124 to move up until the conductive block 124 is engaged with the electrical contact 122. At this time, the squeezing block 123 no longer moves, and the electromagnet 14 electrically connected to the conductive block 124 will have Magnetism: Since the magnetism of the opposite surfaces of the electromagnet 14 and the magnetic plate 16 is the same, the electromagnet 14 will repel the magnetic plate 16, so that the pressing plate 15 moves inward along the inner wall of the accommodating groove 13 under the action of the repulsive force, so that the pressing plate 15 clamps the diamond drill bit, and the diamond drill bit is clamped while being placed in the inner side of the connecting groove 11, avoiding manual fixation, saving time and effort, avoiding the staff from adjusting the fixing mechanism in the test equipment, reducing the work intensity of the staff, and facilitating the large-scale use of the test equipment;

[0035] In the above process, the diamond drill bit enters the inner side of the connecting groove 11, thereby realizing automatic fixation of the diamond drill bit, improving the degree of automation, and realizing fixation of diamond drill bits of different sizes, thereby improving the practicality of the testing equipment;

[0036] When the testing equipment is working, the pressure rod 3 will drive the diamond drill bit to move downward, so that the diamond drill bit contacts with the pressure detection plate 10 and squeezes the pressure detection plate 10. At this time, the pressure detection plate 10 will push the piston plate 9 to move downward along the inner wall of the groove 4, and then the piston plate 9 will squeeze the gas spring 5 and compress the gas in the groove 4, so that the gas inside the groove 4 enters the inner side of the slide groove 7 under the connection effect of the through groove 6, and then pushes the protective cover 8 to move upward. At this moment, the pressure detection plate 10 will be squeezed with the diamond drill bit under the limiting effect of the groove 4, so as to test the hardness of the diamond drill bit, and transmit it to the computer through the internal sensor to record the data. When the pressure applied by the testing equipment to the diamond drill bit reaches the critical value, the diamond drill bit is prevented from cracking under higher pressure, the splashing of diamond drill bit debris is avoided, and the harm to the staff is avoided, thereby improving the safety factor of the testing equipment.
