Abstract
The invention discloses a heading machine cutting part with a high-strength telescoping mechanism. The heading machine cutting part comprises a cutting head, a cutting reducer, a cutting motor, a cutting arm, a motor rack, a cutting motor sleeve and a telescopic cylinder, wherein the cutting motor is arranged in the motor rack; the cutting arm comprises a cutting spindle; the cutting head is rigidly connected with the cutting spindle of the cutting arm by virtue of a high-strength bolt; the cutting arm is connected to the cutting reducer by virtue of a connecting bolt; a cylinder seat of the telescopic cylinder is arranged on the motor rack, and a piston rod of the telescopic cylinder is connected with an outer arm of a cutting motor sleeve; the cutting motor is fixedly arranged in the cutting motor sleeve; the cutting motor sleeve is arranged in the motor rack in a sleeving manner; and the cutting motor sleeve can slide along the axis of the motor rack. According to the heading machine cutting part disclosed by the invention, the cutting motor, the cutting reducer, the cutting arm and the cutting head form a complete transmission system, the cutting motor sleeve and the motor rack form a high-strength telescoping mechanism, telescoping is realized under the action of the telescopic cylinder, the reliability is high, and the dynamic and static load resistance is high.
Description
Technical field
The present invention relates to a kind of cutting part of heading machine, especially relate to a kind of cutting part of heading machine with high strength telescoping mechanism.
Background technology
Soft rock cutting part of heading machine design concept mainly from raising cutting efficiency and shipment efficiency be starting point, its telescoping mechanism limits the cut hardness of cutting units, and in hard rock mole cutting units design process, sacrifice the cutting efficiency of cutting units, be intended to the cut hardness improving cutting units, cause like this in the production status of reality, soft rock cutting part of heading machine encounters hard rock, cutting efficiency falls greatly, pars contractilis fault rate improves, complete machine subtracts greatly application life, and hard rock mole cutting units is when running into soft rock, and cutting efficiency but cannot promote.The cutting units primary structure of existing telescopic fashion comprises: cutting motor, cut reductor, pars contractilis, cutterhead and cut telescopic oil cylinder.Wherein cutting motor output shaft is connected on cut reductor power shaft by spline housing, the output shaft of cut reductor connects with the spline housing with flexible stroke in pars contractilis, the spline housing other end connects cut main shaft input end, cut main shaft output connects cutterhead, constitutes the transmission system of complete set.Pars contractilis is three layers of tube-in-tube structure, comprises flexible inner core, outer telescopic tube and flexible protection cylinder.When cut telescopic oil cylinder works, pars contractilis three layers of tube-in-tube structure produce stretching motion, cut main shaft stretching motion in the spline housing with flexible stroke of pars contractilis inside.The relative telescoping movement of cut main shaft and spline housing, ensure that the continuous of transmission system, and three layers of tube-in-tube structure are the holding structure of pars contractilis, and three layers of extension sleeve structure, be subject to the restriction of cutterhead size, cannot overstriking, internal construction is complicated, the large bearing arrangement size that result in pars contractilis leading portion cannot strengthen, and becomes the weak link in transmission system, when operating mode and severe, extension sleeve confining force is inadequate, easy distortion or assembling were lost efficacy, and cause the large bearing lost of life of leading portion or damage, the transmission system of whole pars contractilis was lost efficacy.
Summary of the invention
The technical problem to be solved in the present invention is to provide the cutting part of heading machine with high strength telescoping mechanism that a kind of cut hardness is high, operating efficiency is stablized, anti-sound load performance is strong.
For solving the problems of the technologies described above, a kind of cutting part of heading machine with high strength telescoping mechanism of the present invention, comprises cutterhead, cut reductor and cutting motor, also comprises cutting arm, motor rack, cutting motor sleeve and telescopic oil cylinder; Described cutting motor is placed in motor rack, and the output shaft of cutting motor is connected with the power shaft of cut reductor, and described cutting arm has cut main shaft, and the output shaft of cut reductor is connected with the cut main shaft of cutting arm; Described cutterhead is rigidly connected by the cut main shaft of high-strength bolt and described cutting arm, and cutting arm passes through connecting bolt being connected on described cut reductor; The cylinder seat of described telescopic oil cylinder is loaded on described motor rack, its piston rod is connected with the outer arm of described cutting motor sleeve, described cutting motor is installed in cutting motor sleeve, and cutting motor jacket casing is located in motor rack, and cutting motor sleeve can along the axial sliding movement of described motor rack.
Adopt the cutting part of heading machine with high strength telescoping mechanism of said structure, cutting motor, cut reductor, cutting arm and cutterhead form a complete transmission system, cutting motor sleeve and motor rack form high strength telescoping mechanism, under the effect of telescopic oil cylinder, realize flexible.Non-telescope link in the middle of complete transmission system, under the drive of cutting motor sleeve, overall elastic movement, achieves uniformity and the continuity of transmission system, and structure of the present invention is simple, gearing efficiency is high, reliability is strong, and anti-sound load performance is strong.
