Description

Depth-adjustable rock-soil investigation drilling machine mast Technical Field The utility model relates to the technical field of rock-soil exploration drilling rigs, in particular to a depth-adjustable mast of a rock-soil exploration drilling rig. Background The rock-soil exploration drilling machine is professional equipment for geological exploration and geotechnical engineering exploration, is mainly used for drilling holes below the ground surface to obtain samples of rock-soil mass and relevant geological information, has various types and models, and can be selected and used according to different geological conditions, exploration requirements and site environments. The mast is an important supporting structure of the drilling machine, the structure of the mast of the traditional drilling machine is usually an integral structure designed based on specific strength and stability requirements, accurate measurement and adjustment are needed for accurately controlling the drilling depth, the existing mast is not provided with a system for accurately measuring the length change of the mast, the drilling depth control is realized by controlling the length of the mast, high-precision depth control is difficult to realize, as the drilling depth is increased, errors can be accumulated continuously, the final drilling depth is larger than the design requirements, and the investigation accuracy requirements cannot be met. Disclosure of utility model The utility model aims to provide a depth-adjustable geotechnical investigation drilling machine mast so as to solve the problems in the background art. In order to achieve the purpose, the technical scheme is that the rock-soil investigation drilling machine mast comprises a bottom frame, wherein two mast bodies are fixedly connected to the surface of the bottom frame, cylinders are sleeved on the surfaces of the two mast bodies, a drilling machine body is installed on the surfaces of the two cylinders, a rotating shaft is installed at one end, far away from the bottom frame, of the two mast bodies, two chains are installed on the surfaces of the rotating shaft, two ends of the chains are fixedly connected with the drilling machine body, an adjusting structure is arranged on the surface of the bottom frame, the adjusting structure comprises a plurality of rectangular rods, the rectangular rods are fixedly connected with the surface of the bottom frame, two rectangular rods are fixedly connected to the two sides of the mast body, a plurality of round holes are formed in the surfaces of the rectangular rods, rectangular pipes are sleeved on the surfaces of the rectangular rods, bolts penetrate through the surfaces of the rectangular pipes in a sliding mode, the size of the bolts is matched with that of the round holes, and a baffle plate is sleeved on the circular arc surface of the two mast bodies. The control device has the advantages that the position of the baffle plate on the mast body is controlled by arranging the adjusting structure, so that the moving distance of the drilling machine body on the mast body is limited, the depth of rock and soil investigation is controlled, and the investigation precision is guaranteed.
