Embodiment Construction

[0020] figure 1 Schematic diagram of the work of the present invention; figure 2 It is a schematic structural diagram of the present invention; as shown in the figure, the clutch type drill pipe connecting device of the present invention includes a drill pipe connector 1 and a hydraulic chuck; the drill pipe connector 1 is coaxially fixed to the main shaft of the drilling power box 2. The hydraulic chuck is used to clamp the drill rod and drive the drill rod to rotate synchronously with the spindle 2 when the drill rod is disassembled; the clutch type drill rod connection device of the present invention combines the drill rod connector 1 with the hydraulic chuck Combination of drill rods, the drill pipe connector is used in combination with the hydraulic chuck. When the drill pipe is connected, the spindle is directly used to drive the drill pipe connector to rotate, and each section of the drill pipe is added in turn, so that no water braid is required. Dismantling and joinin...

Abstract

The invention discloses a clutch type drilling rod connection apparatus comprising a drilling rod connector and a hydraulic chuck. The drilling rod connector is coaxially fixed on a main shaft of drilling into a power case; the hydraulic chuck clamps the drilling rod when the drilling rod is detached, and drives the drilling rod to synchronously rotate with the main shaft; the drilling rod connector and the hydraulic chuck can be combined for use; the chuck is connected with the main shaft via a clutchable way; adjunction of the drilling rod is completed via the drilling rod connector, so detachment and adjunction of a water braid; the drilling rod can be detached via the chuck, so drilling rod adjunction can be simplified and drilling rod adjunction efficiency can be improved; and technical guarantee is provided for intelligent adjunction of the drilling rod.

Description

Technical field [0001] The invention relates to the field of drill rod chucks, in particular to a clutch type drill rod connecting device. Background technique [0002] The chuck is an important part of the drilling rig. Its function is to clamp the drill rod, transmit torque and thrust, and drive the drilling tool to achieve rotation and drilling. Therefore, the quality of the chuck structure directly affects the reliability, scope, and scope of the drilling rig. The length of the drilling tool, the connection of the water braid and the execution of the automatic operation of the drilling rig. [0003] The existing chucks are directly connected to the main shaft by rigid connectors, so that the torque is directly transmitted to the chuck. Slips are used to clamp the drill pipe. There is no sealing function. The cooling water can only pass through the extended drill pipe and the water braid. , So as to enter the working drill pipe and realize the supply of cooling water. When the ...
