Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of clamping devices, in particular to a drill rod clamping device. Background Art
[0002] A drill rod is a mechanical part used for drilling holes. It has different structures depending on the application scenario. One end of the drill rod is often connected to the rotating part of the equipment. The power source of the equipment drives the drill rod to rotate through the rotating part to achieve the drilling operation of the part to be drilled. Most commonly used drill rods are connected by a single thread to achieve a firm connection with the rotating part. However, the connection of the single threaded component structure will cause the thread to loosen during long-term rotation and vibration. The looseness will cause the rotation center of the drill rod to deviate, causing problems in subsequent use. The high-speed rotation may cause the loose drill rod to continue to loosen, and eventually the drill rod connection will be disconnected. The high-speed rotation of the drill rod disengagement poses a major safety hazard and will cause collision damage to surrounding equipment and surrounding construction workers.
[0003] In summary, there are some problems with the drill rod clamping device in terms of the loose connection of the drill rod during use, so it is hoped that a new structure will be proposed to solve the above technical problems. Summary of the Invention
