Abstract

The invention discloses a multi-shaft hydraulic drill with the drill bit intervals being adjustable and a work method of the multi-shaft hydraulic drill with the drill bit intervals being adjustable. Drill bits can slide in sliding grooves and are hydraulically driven by valve-controlled cylinders, and therefore the distance between every two adjacent drill bits can be adjusted. The drill bits are clamped through drill rod fixing devices, so that the drill bits keep dynamic balance when the drill bits drilling holes. Compared with traditional motor drive, hydraulic motor drive has the advantages that the size is small, the weight is light, the drive force is large, stepless speed change can be conducted, and drill bit screw taps can be quite conveniently protected. The power ratio of the hydraulic motors is large, large holes can be drilled in the manner that one hydraulic motor drives the corresponding drill bit, the drill bits can be detached, the application range of a drilling machine is expanded, and the drilling efficiency is improved.

Description

technical field [0001] The invention belongs to the field of drilling machines, and in particular relates to a multi-axis hydraulic drill with adjustable drill bit spacing and a working method. Background technique [0002] The multi-axis drilling with hydraulic drive has related technologies. One is that Shanghai Jintai Engineering Machinery Co., Ltd. Lin Jian et al. proposed a hydraulic mid-drive telescopic multi-axis drilling mixing device. The method is: use multiple drill bits, and the drill pipe is Hollow telescopic drill pipe, the upper end of the drill pipe is connected to the lifting device, the drill pipe can move up and down in the middle drive hydraulic power head, and transmit power, the hydraulic power source is equipped with a connecting frame and the connecting frame is connected with the lifting device by a wire rope, For drilling in deep formations. The other is that Zhejiang Handa Machinery Co., Ltd. Ying Zhida proposed a fully hydraulic intelligent multi...
