Hydraulic rock drill

液压凿岩机

Hydraulic rock drill is a kind of high-efficiency rock drilling equipment powered by high-pressure oil. In the impact rock drilling system, the rock drill is the power mechanism to complete the energy conversion. The drill rod and the connecting sleeve are the power transmission mechanism, and the function of the drill bit is to break the rock to form a gun hole. The hydraulic rock drill is the key equipment of the whole percussive rock drilling system.

The structure of hydraulic rock drill generally includes impact mechanism, rotating mechanism, water supply and powder discharge device, buffer device and lubrication and dust-proof device. The impact part is mainly composed of cylinder, impact piston, accumulator, reversing valve and other major components and sealing device. The main function of the rotating mechanism is to rotate the drill and remove the drill rod, which is mainly composed of a hydraulic motor, a gear set and a sealing device. The water supply and powder discharge device is divided into two forms: central water supply and side water supply. The buffer device includes a buffer piston and a high-pressure accumulator, which are mainly used to absorb and buffer the rebound force of the rock drilling process and reduce the force on the rock drill and the drilling tool. The function of the lubrication dustproof device is to prevent dust from entering the body, and to lubricate the rotating mechanism and the supporting mechanism of the nose and tail.

Lianhuashan drilling tools are imported from France to produce HYD series hydraulic rock drills. The main models are HYD200, HYD300, HYD200E,HYD300E and HYD350E. The product has the characteristics of stable and efficient performance, simple structure and low maintenance cost. It is mainly used in supporting rock drilling jumbo, anchor rock drilling jumbo, shaft drilling rig, blast furnace opening machine and other rock drilling equipment.
