The rotary motion of rock drill is to export the bit shank for arriving drill steel by the bit shank sleeve in turning set, and drill steel drives bore bit rotation
Turn, so as to circular port can be dug out on rock.
Rock drill can produce heat during rotary motion is formed, and the generation of this heat derives from turning set and chisel
Spin friction and sliding friction between rock machine head.The frequency of impact of rock drill be more than 2200 times/minute, mutual lubrication
It is lubricated by the mist of oil being atomized by compressed air.
Rock drill in one hole stream time of Drilling at 15 minutes or so, the head outer surface in this course of work
Temperature can reach 100 DEG C or so.Between bit shank sleeve and drill steel, gap is big simultaneously, there is also sliding friction and rotary friction therebetween
Wipe；Drill steel afterbody subjects greater impact power, and during being measured with infrared thermometer, temperature can reach 300 DEG C.Aggravation bit shank sleeve
The abrasion of hexagonal hole and drill steel afterbody.
Operator changes drill steel in the course of the work for convenience, often with the bottom of glove hand rest head, this
When will scald operator.
Simultaneously because the fit clearance of the two will be increased during production by the effect expanded with heat and contract with cold.Due to gap greatly, bit shank
Set is inherently big with drill steel gap, and such rock drill rocks increasing at work, and the vibration that operates is severe, increased operator
Labor intensity.The increase in gap, also reduces lubricant effect, exacerbates the abrasion of part.
The content of the invention
Problem to be solved in the utility model is to provide one kind for the problems referred to above table when head works can be greatly reduced
Face temperature, effectively improves rock drill service life, can effectively reduce pricker
The water-cooled rock drill bit shank sleeve of the abrasion of tail sleeve hexagonal hole and drill steel afterbody.
In order to solve the above problems, this utility model is employed the following technical solutions：A kind of water-cooled rock drill bit shank sleeve,
Including columnar bit shank sleeve body, on the outer wall of bit shank sleeve body, circumferential groove is offered；
On the inwall of bit shank sleeve, the position corresponding with bit shank sleeve circumferential groove offers bit shank sleeve Internal locking groove；
The second upright opening is provided between bit shank sleeve circumferential groove and bit shank sleeve Internal locking groove；
Second upright opening is vertically arranged with the axis of bit shank sleeve.
Further improve：
Drill steel bit shank is set with bit shank sleeve, and there is between bit shank sleeve and drill steel bit shank the 3rd water for being available for current to pass through
Chamber.
Further improve：
3rd water cavity is connected with the second upright opening.
Bit shank sleeve of this utility model using such scheme, with advantages below：
1st, the temperature on head surface can be greatly reduced, protects can the temperature of head outer surface
Hold at 28-32 DEG C or so, effectively prevent the injury in operation to operator；
2nd, the abrasion of bit shank sleeve hexagonal hole and drill steel afterbody can be effectively reduced, service life is improve.
The utility model is described in further detail with reference to the accompanying drawings and examples.
