Geotechnical drilling device

Abstract

The invention relates to a geotechnical drilling device. The geotechnical drilling device comprises a hydraulic propelling assembly, a rotating and clamping assembly and a drill stem, wherein the rotating and clamping assembly comprises a rotating part and a hydraulic clamping part; the rotating part comprises a base, a hydraulic motor, a transmission belt, a movable transmission wheel and a plurality of tensioning cushion blocks; the hydraulic motor is fixedly arranged on the base, and the hydraulic motor is connected with the movable transmission wheel through the transmission belt; a guide groove is formed in the base; a wheel shaft of the movable transmission wheel is movably arranged in the guide groove; and a spring is arranged between the wheel shaft and the inner wall of the guide groove. According to the geotechnical drilling device provided by the invention, the plurality of tensioning cushion blocks are arranged in a rotating and clamping device which transmits power through the transmission belt, so that the distance between the hydraulic motor and the movable transmission wheel which are connected through the transmission belt can be adjusted, the tension force of the transmission belt can be adjusted, the tensioning cushion blocks can be added in time to ensure that the tension force meets the requirements, the transmission effectiveness is ensured, and adverse effects on the drilling operation progress are avoided.

Description

technical field [0001] The invention relates to the technical field of construction machinery equipment, in particular to a geotechnical engineering drilling device. Background technique [0002] Infrastructure construction is inseparable from rammed foundations, directional blasting, soil anchoring and other engineering content. Among them, soil anchoring is a technology that uses reinforced cement columns to drill holes into rock layers and soil to strengthen rock and soil slopes. Due to the complex terrain of the construction site and the harsh working environment, the stability requirements for drilling equipment or devices are relatively high. At the same time, the working safety and stability of drilling equipment also directly affect the progress and quality of the project. [0003] Existing drilling equipment generally adopts a belt drive to punch holes by driving a drill rod. Because the belt is flexible, it will heat up due to friction after working for a period ...

AI Technical Summary

Problems solved by technology

Because the belt is flexible, it will heat up due to friction after working for a period of time, and the length of the belt will increase greatly. As the working time prolongs, the belt may become loose or even fall off, which will affect power transmission and even affect the progress of the work.
