Description

Transfer device for fixing drill rod in vertical direction Technical Field The utility model belongs to the field of mining drilling rigs, and relates to a transporter for fixing a drill rod in the vertical direction. Background In the age of rapid development of current technology, automated drilling machine technology is advancing to maturity at an unprecedented speed. The automatic drilling machine has the advantages that the full-automatic operation of a series of operations such as loading and unloading of a drill rod, drilling and posture adjustment can be realized, the technical breakthrough greatly improves the efficiency and the safety of drilling operation, the automatic drilling machine is applied in large scale in the disaster prevention and treatment engineering fields such as gas extraction, water exploration and drainage and the like, and the automatic drilling machine plays a vital role in guaranteeing the safe production of underground working places such as coal mines. However, a core component in the automatic drilling machine technology, namely a drill rod conveying system, widely applied in the industry at present still has a plurality of problems to be solved urgently. Currently, most automatic drilling rigs employ a three-section drill pipe conveying system formed by combining double manipulators with a transporter. In this system, the quality of the performance of the transport as a critical component of the transition of the drill rod between the two manipulators directly affects the stability and reliability of the overall drill rod transport system. The existing transporter mainly has two forms of translation and horizontal rotation, and the motion trail of the existing transporter is limited in a horizontal plane. In the operation process, the transfer device clamps two ends of a horizontally placed drill rod by moving and rotating in a horizontal plane, so that the drill rod can be accurately aligned with the drill rod box or the frame, and smooth conveying of the drill rod is realized. However, this design also presents a significant disadvantage in that existing conveyers lack vertical fixation. Due to the lack of fixation in the vertical direction, existing conveyers are inadequate when the drilling machine is required to perform large-inclination drilling operations. Under the large inclination angle working condition, the drill rod can be influenced by a larger gravity component in the vertical direction, and the conventional transfer device can not provide effective fixed support for the drill rod in the vertical plane. The drill rod is easy to shake, deviate and even fall off in the conveying process, so that the accuracy and quality of drilling are seriously affected, safety accidents can be caused, and life safety of operators is threatened. Due to the limitation of the technical bottleneck, the drilling inclination angle range of the existing automatic drilling machine is greatly restricted. In practical application, many working conditions requiring large-dip drilling, such as gas extraction under complex geological conditions, deep underground water detection and the like, are difficult to meet the operation requirements of the existing automatic drilling machine. The application of the automatic drilling machine in the wider field is limited, and the advantages of automation and high efficiency of the automatic drilling machine cannot be fully exerted. In order to break through the technical bottleneck, a transporter capable of fixing the drill rod in the vertical direction needs to be provided, so that the application range of the automatic drilling machine is further widened, and the drilling technology is promoted to develop to a higher level. Disclosure of utility model Therefore, the utility model aims to provide a transporter for fixing drill rods in the vertical direction, which solves the problem that the existing drill rod transporter lacks a drill rod fixing mechanism in the vertical plane, and the drill rods fall down due to inclination movement. In order to achieve the above purpose, the present utility model provides the following technical solutions: The transporter for fixing the drill rod in the vertical direction comprises a bottom plate, supporting blocks, pressing plates and axial compression blocks, wherein the supporting blocks are arranged on the bottom plate and used for supporting the drill rod, the axial compression blocks are arranged on the bottom plate and located on two sides of the supporting blocks, the pressing plates are rotatably connected to the upper parts of the axial compression blocks and located above the supporting blocks, the axial compression blocks axially compress and fix the drill rod from the drill rod, each axial compression block comprises at least one sliding block which is arranged on the bottom plate in a sliding mode, and the pressing plates compress the drill rod on the supporting blocks. Optionally, a sliding cy
