Damping device of hydraulic rock drilling machine

Abstract

The invention discloses a damping device of a hydraulic rock drilling machine, and relates to the technical field of hydraulic rock drilling machine. The damping device of the hydraulic rock drillingmachine comprises a machine box, a handle is fixedly connected to the top of the machine box, and mops are fixedly mounted on the two sides of the machine box. A hydraulic motor is fixedly mounted atthe top of the inner wall of the machine box, and a hydraulic cylinder is fixedly connected to the bottom of the hydraulic motor. A pressure block is slidably connected to the inner wall of the hydraulic cylinder, and a push rod is fixedly connected to the bottom of the pressure block. Partition plates are fixedly connected to the two sides of the inner wall of the machine box, and first fixed blocks are fixedly connected to the bottoms of the partition plates. First connecting rods are fixedly connected to the bottoms of the first fixed blocks, elastic boxes are arranged at the bottom ends ofthe first connecting rods in a penetrating mode, and grill bits are connected to the inner surface of a connector in a threaded mode. The damping device of the hydraulic rock drilling machine solvesthe problems that the vibration is large, the energy transmission efficiency is low and machine parts are seriously damaged due to the fact that the damping device does not exist in a working process.

Description

technical field [0001] The invention relates to the technical field of hydraulic rock drills, in particular to a shock absorber for hydraulic rock drills. Background technique [0002] The rock drill is a tool used to directly mine stone. It drills blastholes on the rock formation so that explosives can be put in to blast the rock, so as to complete the mining of stone or other stone works. In addition, the rock drill can also be converted into a destroyer for crushing For hard layers such as concrete, rock drills can be divided into four categories according to their power sources: pneumatic rock drills, internal combustion rock drills, electric rock drills and hydraulic rock drills. Hydraulic rock drills are a new type of rock drill that has emerged in recent years. Basically, they can be divided into two types. Type: One is a small hand-held type with a small impact energy, which is mainly used to replace the traditional wind pick, most of which are used in conjunction wi...
