Bear the frame including guide bar, loading end, impingement surface, the whole lower surface in bottom that bears the frame is the impingement surface, the drill bit up end is adjusted well to the impingement surface, be equipped with the loading end in the upper end of impingement surface, the guide bar is installed on the loading end, and its advantage is: the drill bit atress is even, the atress direction is accurate, can accomplish the dismantlement task quick, conveniently, and can not produce the additional power of other directions to the damage to drill bit and drilling rod has effectively been avoided.
Description
Technical field
The utility model relates to a kind of specific purpose tool of bit of rock drilling machine, especially a kind of specific purpose tool for dismantling bit of rock drilling machine.
Background technology
Rock drill is a kind of facility conventional in engineering construction, is mainly used in holing to rock or concrete, crushing operation.Bit of rock drilling machine is mainly used in the impulsive force of drilling rod transmission and revolving force to directly act on rock, produces destruction to rock.Due to the situation such as bit wear, drill pipe wear occurred in operation process, often need drill bit to take off from drilling rod to change.
Drill bit due to rock drill takes the mode of interference fit to be directly enclosed within drilling rod, and press tighter and tighter in operation process, causes the dismantlement work of drill bit very difficult.There is no removal tool special at present, when needs dismounting drill bit time typically use iron block, stone etc. conveniently instrument its edge is knocked repeatedly, make it loosen gradually, come off.Because drill bit and drilling rod junction wall thickness are less than 1cm, so when adopting this way to knock, be often difficult to align stress point, operating efficiency is low, dismounting speed is slow; In addition, due to this method of knocking from side, drilling rod and bit force can be made uneven, easily cause the accidental damages such as impaired, fracture.
Summary of the invention
The purpose of this utility model is for the problems referred to above, provides a kind of specific purpose tool for dismantling bit of rock drilling machine.The afterburning mode of impact type taked by this specific purpose tool, utilize carrier that the impulsive force of jump bit is evenly distributed in the surrounding of drill bit, make that bit force is even, Impact direction is accurate, dismounting task can be completed fast, easily, and the additional force in other directions can not be produced, thus effectively prevent the damage to drill bit and drilling rod.
The utility model solves the technical scheme that its technical problem adopts: a kind of specific purpose tool for dismantling bit of rock drilling machine, comprises drilling rod, carrier and jump bit three part.Carrier is divided into left and right two halves, centre is hollow cylinder, at hollow cylinder built with drilling rod, flange is provided with on the top of drilling rod, in the bottom of drilling rod, drill bit is housed, carrier is loaded between drilling rod flange and drill bit, clamps drilling rod by left and right two halves, carrier is adjacent to drilling rod, is combined into one; Described carrier comprises guide post, loading end, shock surface, and the whole lower surface in bottom of carrier is shock surface, and shock surface aligns bit upper end face; Loading end is provided with in the upper end of shock surface, guide post is arranged on loading end, the internal orifice dimension of whole carrier is identical with drill pipe diameter, guide post external diameter is greater than the lip diameter of drilling rod, loading end external diameter is greater than jump bit external diameter, the external diameter of shock surface is identical with bit upper end face diameter, and jump bit is hollow cylinder, and internal diameter is greater than the external diameter of carrier guide post part.
Described guide post is for guiding jump bit axially-movable.
The impulsive force that described loading end produces for carrying jump bit.
Described shock surface is used for upper surface impulsive force being passed to drill bit.
The external diameter of described guide post is greater than the diameter of drilling rod flange, so that install jump bit.
The internal diameter of described jump bit is greater than the external diameter of carrier guide post part, for along guide post axially-movable, applies impulsive force to loading end.
Owing to adopting technique scheme, the beneficial effects of the utility model are: bit force is even, Impact direction is accurate, dismounting task can be completed fast, easily, and the additional force in other directions can not be produced, thus effectively prevent the damage to drill bit and drilling rod.
