Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of drilling devices, and more specifically, relates to a drill rod lifting tower. Background Art
[0002] During the drilling process, the torque and gravity of the drill pipe will be affected by factors such as the resistance of solid and liquid formations and the topography. Therefore, a component is needed to ensure the stability and efficiency of the drill pipe and avoid deformation of the drill pipe that affects the normal progress of drilling work. The role of the short section is to connect the drill pipe components, support and withstand its torque and gravity, and ensure the stability and efficiency of drilling.
[0003] Based on the above, the inventors found that the following problems exist: during the drill rod lifting process, mud will remain on the drill rod. The general treatment method is to remove the drill rod and then manually clean it by spraying. This method may result in incomplete cleaning of the mud on the drill rod. At the same time, it cannot be cleaned when the drill rod is lifted, which is more troublesome and not conducive to improving overall efficiency.
[0004] Therefore, in view of this, the existing structure and defects are studied and improved, and a drill rod lifting tower is provided to achieve a purpose with greater practical value. Utility Model Content

[0013] Compared with the prior art, the present invention has the following beneficial effects:
[0014] In the utility model, the annular scraper is fixed to the inner side of the mounting ring by fixing bolts. The annular scrapers with different inner diameters can be replaced according to the diameter of the drill rod. Then the drill rod is passed through the inside of the through groove and lifted by the lifting device. At this time, the drill rod passes through the inside of the annular scraper, and the mud on the side of the drill rod can be cleaned.
[0015] In the utility model, the push column is driven to rotate by rotating the rotating disk. When the push column rotates, it can move upward or downward through the thread. At this time, the upper part of the push column can push one end of the fixed cylinder to move. The fixed cylinder will move around the connecting shaft at this time.
