High-precision table type rotating ultrasonic rock coring device

Abstract

The invention discloses a high-precision table type rotating ultrasonic rock coring device, and belongs to the technical field of rock coring. The device comprises a supporting assembly, a transmission assembly and an ultrasonic rock breaking assembly. The supporting assembly is located on the outmost side of the whole device, the transmission assembly is located on the upper end in the supportingassembly, the ultrasonic rock breaking assembly is mounted on the lower end in the supporting assembly, the device is scientific and reasonable, use is safe and convenient, ultrasonic vibration is used for carrying out resonance breaking on the rock, compared with a traditional manner that a drill bit drills for coring, the coring efficiency is greatly improved, a rock sample can be subjected tosurface grinding through the device, the surface of a coring sample is flat, the rock sample can enter a coring groove favorably, a related worker can carry out observing and research, when the top end of the coring rock sample reaches the height of a distance sensor, the device can cut off the rock sample, the cut-off rock coring sample can be conveniently taken out by an operator from the top ofa coring groove, and convenience and rapidness are achieved.

Description

technical field [0001] The invention relates to the technical field of rock coring, in particular to a high-precision desktop rotary ultrasonic rock coring device. Background technique [0002] Geological researchers can understand the history of the region through rock coring. Coring is done through a coring barrel. The traditional coring barrel is connected to the bottom end of the drill pipe close to the drill bit. After the core cutting head cuts into the formation, the coring barrel can be used Continuous coring, and then take it out from the drill pipe, most places use the wireline coring barrel, because in the process of coring, there is no need to take the drill pipe out of the well to take the core, and then continue to take the core, on the contrary, only need to take the core The core barrel is put into the drill pipe, automatically locked in the coring position, reaches the bottom of the well, and performs continuous coring. However, the coring efficiency of the ...

[0002] Geological researchers can understand the history of the region through rock coring. Coring is done through a coring barrel. The traditional coring barrel is connected to the bottom end of the drill pipe close to the drill bit. After the core cutting head cuts into the formation, the coring barrel can be used Continuous coring, and then take it out from the drill pipe, most places use the wireline coring barrel, because in the process of coring, there is no need to take the drill pipe out of the well to take the core, and then continue to take the core, on the contrary, only need to take the core The core barrel is put into the drill pipe, automatically locked in the coring position, reaches the bottom of the well, and performs continuous coring. However, the coring efficiency of the existing coring device is slow, and each time the coring needs to be repeatedly extracted from the inner coring barrel for rock The sample is taken out, and the surface of the rock sample taken out by the existing device is rough, because the drill bit is easy to skew, which makes the quality of the core poor, which is not conducive to the observation and research of relevant personnel, so people need a high-precision desktop rotary ultrasonic rock coring device. solve the above problems
