Embodiment Construction

[0030] The present invention will be further described below in conjunction with the accompanying drawings.

[0031] like figure 1 As shown, the soil remediation sampling drilling rig using a high-frequency hydraulic power head in this embodiment includes a high-frequency hydraulic power head 1, a control console 2, a thrust cylinder 3 and a working support 4; wherein, the high-frequency hydraulic power head 1 is the whole equipment It can provide high-frequency impact force, so that the drill pipe can quickly enter the predetermined underground position, and when necessary, the power head can be rotated under the drive of the rotary motor 62, forming a compound action of impact and rotation , to adapt to some special working conditions, such as environmental engineering, geotechnical, geothermal and survey. The manipulation console 2 is the command center of the entire device, and the staff can achieve desired work and effects by controlling the manipulation console 2 . The...

Abstract

The invention provides a high-frequency hydraulic power head and a soil restoration sampling drilling machine using the power head. The high-frequency hydraulic power head comprises a support frame, a power head transmission box, a hydraulic power hammer and a transmission shaft, wherein the power head transmission box, the hydraulic power hammer and the transmission shaft are arranged on the support frame; the hydraulic power hammer is arranged above the power head transmission box; the transmission shaft is arranged inside the power head transmission box; the lower end of the transmission shaft is connected with a drill rod; the power head transmission box comprises an upper support frame, a box body, a pipe lifting assembly, a pipe pulling mechanism, a support plate assembly, a lower support frame, a bearing and a sealing sleeve. The high-frequency hydraulic power head has the advantages that the design is reasonable; the structure is compact; through the reasonable parameter matching, the unique hydraulic impact hammer is designed; the problem of poor quality of the original soil sampling drilling machine sample is solved; through the special transmission shaft, the working problems of high frequency impact and rotary recombination are solved; the power head transmission box structure is ingeniously matched with the transmission shaft, so that the optimization problem of a thrust conduction route and a stress structure during the drill rod being pressed under impact is solved.

Description

technical field [0001] The invention specifically relates to a high-frequency hydraulic power head and a soil remediation sampling drilling rig using the power head, belonging to the technical field of engineering machinery. Background technique [0002] Vibration drilling technology is a processing technology that improves the drilling process by adding a vibrating motion during the drilling process. However, most of the existing vibration drilling mechanisms have complex structures and unsatisfactory working mechanisms. [0003] Traditional rotary drilling rigs and traditional low-frequency drilling rigs, in the process of soil sampling and restoration, the quality of soil samples obtained is very poor, destroying their original characteristics, and cannot meet the requirements of testing research and engineering and technical personnel. In addition, the existing drilling rigs also have the problem of high-frequency impact and rotary composite work, and the optimization of...
