Abstract
The invention relates to a tamping device. An oil motor of the tamping device is in transmission connection with an eccentric shaft mechanism by a gear transmission mechanism, wherein the middle part of each tamping arm is installed on and interlocked with the eccentric shaft mechanism, clamping oil cylinders are respectively installed on the upper parts of the tamping arms, the other end of each clamping oil cylinder is fixed on each oil cylinder permanent seat or a box body, and the lower part of each tamping arm is provided with a tamping pick. By utilizing the gear transmission, the tamping device causes each tamping arm installed on the eccentric shaft mechanism to rotate; being retrained by the clamping oil cylinders, nodal points on the upper ends of the tamping arms force the lower tamping picks to make relative movement to generate elliptical vibration when the lower tamping picks are contacted with ballast, thereby compacting the ballast; and by the reciprocating movement of pistons, the inner and outer clamping oil cylinders which are respectively arranged along both longitudinal sides of each sleeper cause the pick heads to make clamping movement in the concomitant elliptical vibration so as to compact the ballast among the sleepers towards the bottom thereof, thereby tamping, fixing and compacting the lower ballast under the sleepers.

Existing tamping unit, the vibration during work all belong to eccentric shaft vibration (vibration of likeness in form seesaw type), clipping tamping unit.Chinese invention patent ublic specification of application CN1125281A discloses a kind of tamping unit, can make two adjacent sleepers simultaneously firm by ramming, and a wherein outside tamping agency lifting separately has the drive unit of opening and closing and vibration, belongs to above-mentioned eccentric shaft vibration.Chinese invention patent ublic specification of application CN1156774A, CN1281921A, CN1469009 disclose several tamping units, all belong to above-mentioned eccentric shaft vibration.Its structure of existing tamping unit (seeing accompanying drawing 1) is that eccentric shaft is connected with tamping arm through the clamping oil cylinder.During work, on the one hand, the eccentric shaft rotation drives tamping arm by the clamping oil cylinder and swings, and realizes the connecting rod transmission, makes the tamping pickaxe rocking vibration of bottom; On the other hand, by changing the in-oil cylinder oil pressure of clamping, the cylinder inner carrier is moved, the push-and-pull tamping arm is done swing by a larger margin, makes tamping pickaxe carry out clamping to the railway roadbed ballast.Therefore, tamping pickaxe is swing vibration and clamping to the effect of ballast aggregate.
Summary of the invention
The oscillation trajectory that the object of the present invention is to provide a kind of tamping pickaxe is that shape is like elliptical path, tamping pickaxe in the course of the work with manipulating object---relatively move when rubble contacts, to shift a part of power, thereby effectively reduce the suffered impact of vibrating member, can improve the tamping unit of service life of equipment.
Technical scheme of the present invention comprises casing, suspension plate, lead, oil pump, fuel tank, oil motor is connected with the eccentric shaft mechanism driving through gear drive, tamping arm middle part be loaded on its eccentric shaft mechanism and with its interlock, the clamping oil cylinder is equipped with in the tamping arm top, the other end of clamping oil cylinder is fixed on casing or the oil cylinder holder, tamping pickaxe is arranged at its tamping arm bottom, and the oscillation trajectory of tamping pickaxe is that shape is like elliptical path.
Eccentric shaft of the present invention mechanism comprises an eccentric shaft, and the tamping arm middle part is loaded on eccentric shaft respectively and links with eccentric shaft.
Eccentric shaft of the present invention mechanism comprises the vibrating shaft in the driven gear on the gear drive, and the tamping arm middle part is loaded on the eccentric part of vibrating shaft, and links with vibrating shaft.
Eccentric shaft of the present invention mechanism is the N cover, along the rail symmetric arrangement 2N tamping arm is arranged through N eccentric shaft or vibrating shaft.
N of the present invention overlaps eccentric shaft mechanism and along the rail symmetric arrangement 2N tamping arm is arranged, and wherein N is 〉=2 even number.
Eccentric shaft or vibrating shaft that of the present invention and gear drive are in transmission connection are four, along rail vertical and horizontal symmetric arrangement eight tamping arms are arranged through four eccentric shafts or vibrating shaft, each tamping arm with separately independently the clamping oil cylinder link to each other with tamping pickaxe.
The present invention drives the rotation of eccentric shaft or vibrating shaft by oil motor driven gear transmission mechanism, with the tamping arm of its interlock up under the constraint of clamping oil cylinder, relatively moves when forcing the below tamping pickaxe to contact with ballast aggregate, and the generation elliptic vibration makes ballast aggregate closely knit.Elliptical motion itself can shift a part of power, thereby can effectively reduce the suffered impact of vibrating member.Simultaneously, the medial and lateral oil cylinder of arranging along the vertical both sides of sleeper passes through reciprocating motion of the pistons, the medial and lateral tamping pickaxe is partnered, in the elliptic vibration of following, make pick produce clamping movement, ballast aggregate is to the extruding of the pillow end between will resting the head on, realization is closely knit to making firm by ramming of ballast aggregate under the sleeper, to improve track stability, guarantees traffic safety.Because of each tamping arm by separately independently oil cylinder drive respectively, during operation, can make the asynchronous clamping of rail medial and lateral tamping pickaxe, make make firm by ramming the back ballast aggregate compactness be consistent; The independent clamping of tamping pickaxe of pick or rail one side in one pair is to realize the special operation requirement.
