Abstract

A double-impact integral hydraulic tapping machine comprises a borer assembly. A front support device, an impact device and a rotary device are sequentially arranged on the outer portion of the borer assembly from front to back, a backstop assembly is arranged at the rear end of the borer assembly, a rotary joint assembly is arranged at the outer end of the backstop assembly, the borer assembly comprises a rapping rod, a drill stem connecting sleeve is connected to the front end of the rapping rod, and the impact device comprises an impact functional module and a reversing control functional module. The double-impact integral hydraulic tapping machine has the advantages that the double-impact integral hydraulic tapping machine is adaptable to hard iron notches, is high in reverse impact output power and prevents the problem of stem withdrawal; a forward impact device and a reverse impact device are integrated, reverse impact operation can be carried out by retreating a trolley when the drill stem is required to be withdrawn, the stem withdrawal time is shortened, and misoperation is avoided; the double-impact integral hydraulic tapping machine is in a modular design, and is high in maintainability and low in failure rate; and the double-impact integral hydraulic tapping machine is high in protection performance, and the service life of equipment is long.

Description

technical field [0001] The invention relates to a high-efficiency double-strike integrated hydraulic opening machine, which is suitable for the front opening of large and medium-sized ironmaking blast furnaces, mining rock drilling, metallurgical material tank cleaning, emergency rescue and the like. Background technique [0002] At present, the difficulty of opening the taphole in blast furnace smelting is increasing day by day. The main reasons are: the sintering strength of the blast furnace taphole is significantly improved, the sintering hardness of the refractory material is high, iron is contained in the taphole, and the actual load capacity of the existing blast furnace equipment foundation and structural parts is relatively small. There are restrictions on the self-weight of the opening machine. In the face of such working conditions, the main problems exposed by the existing drilling machines are: the actual output impact power is small, the frequency is low, and t...
