Technical Field

The invention mainly relates to a ratchet type drilling tool connecting device which is mainly used for a drill rod joint structure for geological exploration and is widely applied to various drill rods.

Background

In geological exploration, drill rods work through connection of a drilling machine, and are connected in sections through various connection structures according to drilling depths, and the connection modes include various connection modes such as a threaded connection mode, a square connection mode or a hexagonal connection mode.

Disclosure of Invention

The invention mainly provides a ratchet type drilling tool connecting device, aiming at the defects of the prior art in threaded connection, a ratchet structure is arranged at the nose end of a male joint and is matched with a wedge block mechanism arranged on a female joint to prevent reverse rotation so as to prevent a drill rod from falling off and losing, and the male joint and the female joint can rotate away from the drill rod and fall off only when a clamping device clamps the wedge block mechanism on the female joint when a drilling machine dismantles the drill rod.

The invention ensures that the male and female connectors are rotated away from the drill rod and fall off and are lost when the drilling machine rotates reversely, thereby avoiding economic loss and increasing drilling efficiency. The invention mainly comprises a male connector, a female connector and a wedge block mechanism.

The ratchet type drilling tool connecting device mainly comprises a male connector, a female connector and a wedge block structure.

The ratchet type drilling tool connecting device comprises a male connector and a ratchet wheel at the nose end of the male connector, wherein the male connector comprises male connector external threads.

Wherein a ratchet formula drilling tool connecting device, female joint includes: female joint internal thread, female joint nose end hole, voussoir structure.

Wherein a ratchet formula drilling tool connecting device, the voussoir mechanism includes: sliding pin, spring, slider, cylindric lock.

According to the ratchet type drilling tool connecting device, the sliding pin is provided with the long hole, and the sliding pin slides back and forth by the cylindrical pin.

The ratchet wheel type drilling tool connecting device is characterized in that internal threads and a nose end inner hole are formed in a female joint, a pin hole is formed in the outer wall of the nose end of the female joint and provided with a wedge block mechanism, and a male joint nose end ratchet wheel and the wedge block mechanism are used for preventing the male joint and the female joint from rotating away to prevent a drill rod from falling off in the process of screwing the male joint and the female joint. When the drilling machine is used for disassembling a drill rod, the clamping device works to clamp the sliding pin in the wedge block mechanism, the sliding pin pushes the sliding block, the sliding block rises to prevent the male joint and the female joint from reversely rotating and unscrewing, at the moment, the drilling machine reversely rotates the male joint and the female joint to disengage from the drill rod, the drill rod is disassembled, and the spring reset sliding block falls back and recovers to prevent the male joint and the female joint from reversely rotating and unscrewing.

Detailed Description

Reference is made to the figures contained in the accompanying drawings and in which is shown, by way of illustration and specific application, the following:

according to the drawing, the ratchet type drilling tool connecting device is characterized in that internal threads 203 and a nose inner hole 202 are arranged in a female joint 2, a pin hole 201 is formed in the outer wall of the nose of the female joint 2 and is provided with a wedge mechanism 3, a sliding pin 301 is provided with a long hole and slides back and forth by using a cylindrical pin 304, and a male joint 1 and the female joint 2 are prevented from rotating away from each other to prevent a drill rod from falling off due to reverse rotation by using a male joint nose ratchet 101 and the wedge mechanism 3 in the process of screwing the male joint 1 and the female joint 2. When the drill rig dismantles a drill rod, the clamper works to clamp the sliding pin 301 in the wedge block mechanism 3, the sliding pin 301 pushes the sliding block 302, the sliding block 302 rises to prevent the reverse rotation and the unscrewing of the male joint and the female joint from canceling, at the moment, the drill rig reversely rotates the male joint and the female joint to unscrew the drill rod and fall off, the drill rod dismantling is completed, and the spring 303 resets the sliding block 302 to fall back and restore to prevent the reverse rotation and the unscrewing of the male joint and.
