The carriage device of the power head and the drilling rig

Abstract

The invention discloses a power head carriage device and a drilling machine; the power head carriage device comprises a carriage body and a first guide roller assembly; the first guide roller assembly is arranged on the carriage body, and comprises a roller mounting structure, a first guide roller and a second guide roller; the first and second guide rollers are arranged on the roller mounting structure; the center distance between the first and second guide rollers is adjustable, thus effectively ensuring the peripheries of the first and second guide rollers to fit with a guide rail, and solving the problems that the gap between the rollers and guide rail cannot be timely adjusted after expansion.

Description

technical field [0001] The invention relates to the field of construction machinery, in particular to a sliding frame device of a power head and a drilling rig. Background technique [0002] The vehicle-mounted deep well drilling rig is a multifunctional drilling rig widely used in drilling operations such as deepwater wells, coalbed methane wells, geothermal wells, rescue wells, etc. It has the characteristics of fast transition and good modularization. As an important part of a deep well drilling rig, the power head's guiding and limiting structure during drilling will directly affect the drilling accuracy, work efficiency and service life of related components. [0003] figure 1 Shown is the carriage arrangement of a prior art powerhead. The carriage device of the power head includes a carriage body 10', a roller mounting structure 21', a first guide roller 22' and a second guide roller 23'. Wherein, the carriage main body 10' is used for installing the power head, and...

AI Technical Summary

Problems solved by technology

[0004] The carriage device of the power head in the above scheme can effectively reduce the resistance when the power head moves, but the first guide roller 22' and the second guide roller 23' will be worn after long-term work, and the first guide roller 22' and the second guide roller The gap between the second guide roller 23' and the guide rail gradually increases, which will cause the power head to swing seriously, which will cause drilling instability and seriously affect the drilling accuracy

[0005] Therefore, the carriage device of the power head in the prior art has the problem that the gap between the roller and the guide rail cannot be adjusted in time after the roller has been worn for a long time.
