Description
Technical field:
The utility model relates to a kind of jumbolter that is used in mine laneway boring.
Background technology:
The bolt support mode of coal mine roadway have supporting safe and reliable, become that lane speed is fast, labour intensity is low, integrated cost is low, tunnel utilization rate advantages of higher, the application in China's coal-mine more and more widely becomes the important development direction of current roadway support.Jumbolter also is used widely as the boring bar tool of anchor shaft anchor cable supporting.Jumbolter mainly is made of motor and drive disk assembly, noise damper, supporting leg seat, control arm parts, air leg parts.Compressed air enters motor by the control arm parts, the CD-ROM drive motor rotation, after the cylindrical gear of straight tooth deceleration by drive disk assembly transmission of power is arrived output shaft, output shaft drives the hexagonal kelly rotation, compressed air enters the air leg parts by control arm simultaneously, air leg stretches out under the compressed air effect, and the drill bit that is installed in the drilling rod top is contacted with top board all the time, realizes that it creeps into function.Its shortcoming is that this kind rig only rotatablely moves and can't creep into operation when formation hardness surpasses f8.
Summary of the invention:
The purpose of this utility model provides the dual-purpose jumbolter of a kind of impact type, and when formation hardness during greater than f8, rig is realized the function of holing under rotation and percussion.
The purpose of this utility model realizes as follows: this jumbolter relates to motor, drive disk assembly, noise damper, supporting leg seat, the gentle pin components of control arm parts, annexation between them is same as the prior art, is characterized in installing additional on the drive disk assembly output shaft cover percussion mechanism.
Percussion mechanism is combined with reduction box, the output shaft of drive disk assembly and is constituted by profile of tooth wheel disc, impact wheel disc, conversion sleeve, the profile of tooth wheel disc is enclosed within on the output shaft and is fixed on the reduction box casing, impacting wheel disc is fixed together by screw thread on the profile of tooth wheel disc and with output shaft, the profile of tooth wheel disc has corresponding profile of tooth with the impact wheel disc and meshes together, when motor drives the output shaft rotation, profile of tooth wheel disc transfixion, the impact wheel disc rotates with the axis, engagement disengaging along with its profile of tooth, output shaft is the high speed play up and down, realizes impact function.In order to realize that rig impacts and the not conversion of impact property, has added a conversion sleeve.Conversion sleeve is contained in the reduction box and cylindrical is mated, the conversion sleeve lower surface is in the top of profile of tooth wheel disc upper surface, be supported with bearing between conversion sleeve top and the output shaft, have when moving on the bearing its inner ring support last boss on the output shaft, the conversion sleeve endoporus has the boss that is against bearing outer ring when moving on it; There is one or several breach conversion sleeve circumference bottom surface, and it is oblique line or curve that the top outline line of breach launches the back; Profile of tooth wheel disc corresponding conversion cover gap position has projection; Conversion sleeve circumferentially is connected with water jacket.When not needing impact property, rotate water jacket and drive the conversion sleeve rotation, the projection of profile of tooth wheel disc withstands on the oblique line or curve of conversion sleeve circumference bottom surface breach, conversion sleeve is moved up, driving output shaft by bearing moves up, impact wheel disc and toothed wheel disk detachment thereby make, can only smooth rotation when rig is worked, identical with general jumbolter function.
The circumferential connected mode of conversion sleeve and water jacket is at water jacket and conversion sleeve upper end contact position several protrusion teeth to be arranged, and the conversion sleeve upper end is protruded tooth and stretched in corresponding breach having and protruding the breach that tooth matches.
This rig is to set up a cover beater mechanism on the common bolt rig, and can carry out the function conversion to it by switching mechanism, can select only to rotate according to on-the-spot ROCK CONDITIONS still be the function that rotating band impacts, and compliance is stronger, can reach best duty, improve operating efficiency.The experiment proved that dependable performance, cost increases little.
Description of drawings:
Fig. 1 is the external structure schematic diagram of the dual-purpose jumbolter of the utility model impact type.
Fig. 2 is the structural representation of motor and drive disk assembly part.
The specific embodiment:
With reference to Fig. 1, this rig is made of motor 2, drive disk assembly 1, noise damper 3, supporting leg seat 4, control arm parts 5 gentle pin components 6, installs a cover percussion mechanism on the output shaft 9 of drive disk assembly additional.
With reference to Fig. 2, the top of air motor 2 connects drive disk assembly 1, and drive disk assembly 1 is made of reduction box 7, output shaft 9 etc.The power of air motor 2 outputs to splined shaft 8 by reduction box 7 through the gear train transmission, and splined shaft 8 upper ends connect output shaft 9 by spline, and the rotary power of motor passes to output shaft 9 after slowing down like this.Increased by a cover percussion mechanism in output shaft 9 parts, percussion mechanism is by profile of tooth wheel disc 10, impact wheel disc 11, the reduction box 7 of conversion sleeve 12 and drive disk assembly, output shaft 9 is in conjunction with constituting, profile of tooth wheel disc 10 is enclosed within on the output shaft 9 and is fixed on reduction box 7 casings, impacting wheel disc 11 is fixed together by screw thread on profile of tooth wheel disc 10 and with output shaft 9, profile of tooth wheel disc 10 has corresponding profile of tooth with impact wheel disc 11 and meshes together, conversion sleeve 12 is contained in the reduction box 7 and cylindrical is mated, conversion sleeve 12 lower surfaces are in the top of profile of tooth wheel disc 10 upper surfaces, be supported with bearing between conversion sleeve 12 tops and the output shaft 9, have when moving on the bearing its inner ring support last boss on the output shaft 9, conversion sleeve 12 endoporus have the boss that is against bearing outer ring when moving on it; There is one or several breach conversion sleeve 12 circumference bottom surfaces, and it is oblique line or curve that the top outline line of breach launches the back; Profile of tooth wheel disc 10 corresponding conversion are overlapped 12 gap positions projection; Have 4 to protrude teeth at water jacket 13 and conversion sleeve 12 upper end contact positions, conversion sleeve 12 upper ends are protruded tooth and are stretched in corresponding breach having and protruding the breach that tooth matches, the circumferential connection between realization conversion sleeve 12 and the water jacket 13.When the needs impact function, impact wheel disc 11 is in lowest positions and profile of tooth wheel disc 10 sticks together, when motor rotates, profile of tooth wheel disc 10 transfixions are impacted wheel disc 11 and are rotated with the axis, along with the engagement disengaging of its profile of tooth, output shaft 9 is the high speed play up and down, realizes impact function; When not needing rig to impact, rotation water jacket 13, the moving conversion sleeve 12 of 4 protrusion cingulums on the water jacket 13 rotates to make on it and moves, conversion sleeve 12 drives to impact on the wheel disc 11 and moves, make and impact wheel disc 11 and break away from profile of tooth wheel disc 10, can only smooth rotation during rig work, identical with general jumbolter function.
