The hydraulic hand-holding side roof bolter is convenient to use, can effectively buffer the vibration generated in the process of adjusting an operating arm through the connecting device so as to protect the hydraulic cylinder and the hydraulic motor,and the service life of the hydraulic hand-holding side roof bolter is prolonged.
Description
technical field [0001] The invention relates to the technical field of drilling rigs, in particular to a hydraulic hand-held rock bolt drilling rig. Background technique [0002] The single-body hydraulic rock bolter needs to be used in conjunction with an auxiliary pump station, or used in parallel on an operating machine with a hydraulic system. It is a special support tool for coal mine entry and exit roadways. The rock bolter is mainly used for drilling operations in coal roadway bolt support, and its load mainly includes the rock anti-pressure acting on the oil cylinder and the rock cutting force acting on the motor. [0003] After searching, the Chinese patent authorization number CN203948021U discloses a hydraulic rock bolter, including a hydraulic motor, a rig handrail, a connecting plate, a hydraulic cylinder and a control arm. The control arm is in the shape of a cantilever, and one end of the control arm is provided with the The oil distribution shaft connected w...
