Embodiment Construction

[0017] see figure 1 and figure 2 As shown, the spear head 1 of the present invention is connected with the cartridge recovery pipe 3, and the cartridge recovery pipe 3 forms a movable connection with the cartridge seat 7 through the first elastic pin 2. When the cartridge recovery pipe 3 goes up, the bullet caliper 5 Gravity falls, and the bullet caliper 5 is connected with the bullet holder 7 through the second elastic pin 6,

[0018] When the bullet holder 7 goes down, it drives the bullet caliper 5 to go down together. When the bullet caliper 5 is closed by the thrust of the bullet recovery tube 3, the two pieces of the bullet caliper 5 remain open, and the two pieces of the bullet caliper 5 are stuck on the spring 4 to ensure that the inner tube 23 will not go up due to the thrust generated during the drilling process; the piezoelectric ceramic vibrator 31 reaches the inner diameter reinforcement of the outer tube 12, the battery 27 and the piezoelectric ceramic vibrator...

Abstract

The invention discloses an ultrasonic vibration cord coring drill tool. The ultrasonic vibration cord coring drill tool is characterized in that power can be supplied to a piezoelectric ceramic vibrator by a battery of the ultrasonic vibration cord coring drill tool, high-frequency voltages with different frequencies can be provided, and accordingly the piezoelectric ceramic vibrator can be excited to ultrasonically vibrate; generated ultrasonic vibration is transmitted to rock via an outer tube and a drill bit, and resonance breaking can be carried out on the rock; single-action characteristics of rock core tubes are kept among the battery, the piezoelectric ceramic vibrator and a solid shaft by the aid of bearings. The ultrasonic vibration cord coring drill tool has the advantages that the ultrasonic vibration cord coring drill tool is convenient to replace, the application range of ultrasonic drilling can be greatly expanded, the drilling periods can be shortened, and the cord coring drilling speeds can be increased.

Description

technical field [0001] The invention relates to an ultrasonic vibration rope core drilling tool, which is suitable for deep-hole geological core drilling, and specifically relates to the use of ultrasonic vibration to perform fatigue damage to hard rocks and rapidly drill. Background technique [0002] With the rapid development of the economy, the consumption of energy is also increasing day by day, and shallow oil, coal, natural gas and other energy sources are exploited in large quantities. Judging from their remaining reserves, the proven shallow energy can no longer continue to support modern industry for a long time. Therefore, it is particularly important to use geological core drilling to explore the energy storage in deeper formations, and the rope coring method is the first choice for geological core drilling. Wireline core drilling has become the main drilling method for geological drilling in my country. However, due to the relatively thick wall of the wireline ...
