Abstract
The invention provides a positive wire double-pillow tamping device, which comprises a rack, an eccentric shaft arranged on the rack, two inner tamping picks, two outer tamping picks and a driving oil cylinder. The device is characterized in that the eccentric shaft is connected with one end of each of two symmetrical horizontal upper oil cylinders, the other ends of the two horizontal upper oil cylinders are connected with pick arms of the two inner tamping picks hinged on the rack respectively, and the pick arms of the two inner tamping picks are connected with pick arms of the two outer tamping picks hinged on the rack through corresponding two horizontal lower oil cylinders respectively. An excitation force from the eccentric shaft is transferred to the two inner tamping picks, the two horizontal lower oil cylinders and the two outer tamping picks in turn through the two horizontal upper oil cylinders so as to finish the vibration of the two inner tamping picks and the two outer tamping picks; and meanwhile, the clamping motions of the two inner tamping picks and the two outer tamping picks are synchronously controlled through the two horizontal lower oil cylinders so as to rearrange road stones thickly. The device can greatly improve the stress conditions of the eccentric shaft and a bearing, reduce the high-strength requirements of the eccentric shaft and the bearing, further reduce the input power, improve the work efficiency of a tamping device, prolong the service life of the tamping device and lower the production cost.
Description
Technical field
The present invention relates to a kind of tamping unit, the positive wire double-pillow tamping device that especially a kind of railway track mechanization maintenance is used belongs to the railway maintenance field of mechanical technique.
Background technology
Tamping unit is one of groundwork device in the railway track mechanization maintenance.It comprises elevator platform, be hinged on the elevator platform by hinge, and by its inside and outside tamping pickaxe around the hinge swing of inside and outside clamping hydraulic oil cylinder driving, with under the effect of the exciting force of the relative chucking power of inside and outside tamping pickaxe output and the output of each tamping pickaxe, make the railway ballast under the sleeper be rearranged closely knit, thereby reach the purpose that improves track lateral resistance and longitudinal resistance, guarantee train driving safety.
Existing tamping unit as shown in Figure 1, because in driving, outer tamping pickaxe do holding action in, outer clamping oil cylinder all directly is contained on the eccentric shaft on the frame, outer clamping oil cylinder is overhanging and eccentric shaft is produced a thrust during clamping, interior clamping oil cylinder bounces back and eccentric shaft is produced a pulling force, thrust and pulling force produce vertically downward make a concerted effort to directly act on the eccentric shaft, this just requires eccentric shaft must possess higher intensity, simultaneously, because chucking power, exciting force all will be born by the bearing that is contained on the eccentric shaft, this just requires bearing also must possess higher intensity, and to obtain high-intensity eccentric shaft and bearing, certainly will increase material investment or difficulty of processing, thereby increase cost of production and business economic burden, be unfavorable for saving, also be unfavorable for producing.Therefore, must be improved prior art.
Summary of the invention
The technical problem to be solved in the present invention is exactly that a kind of two pillow tamping units that can be used for the railway main track will be provided, under the prerequisite that satisfies rail track main track tamping operation, the existing tamping unit of solution requires them must have higher intensity greatly because of the bearing capacity of eccentric shaft and bearing, thereby increase material investment or difficulty of processing, until increasing problems such as cost of production and business economic burden.
For solving the problems of the technologies described above, the invention provides a kind of like this positive wire double-pillow tamping device, comprise frame, be located at eccentric shaft and two interior tamping pickaxes on the frame, two outer tamping pickaxes and drive oil cylinder, it is characterized in that eccentric shaft links to each other with symmetrically arranged two horizontal upper cylinder one ends, the two upper cylinder other ends respectively be hinged on frame on two in tamping pickaxe pick arms link to each other, tamping pickaxe pick arms link to each other with two outer tamping pickaxe pick arms on being hinged on frame by oil cylinder under two levels of correspondence setting respectively in two, in order to will be passed to interior tamping pickaxe successively from the exciting force of eccentric shaft by upper cylinder, following oil cylinder, outer tamping pickaxe is in finishing, the vibration of outer tamping pickaxe; Pass through the holding action of the inside and outside tamping pickaxe of oil cylinder Synchronization Control down simultaneously, closely knit so that railway ballast is rearranged.
Tamping pickaxe is hinged on the frame by the axis hole of its pick arm lower end and the hinge in the axis hole in described, in order to finish swing around hinge, thus clamping railway ballast and make it closely knit.
Described outer tamping pickaxe is hinged on the frame by the axis hole of its pick arm lower end and the hinge in the axis hole, in order to finish swing around hinge, thus clamping railway ballast and make it closely knit.
Described eccentric shaft links to each other with power drill/driver, so that under power drill/driver drives, eccentric shaft is rotated, and produces exciting force simultaneously and outwards output.
Described power drill/driver is hydraulic motor and the reduction box that links to each other with hydraulic motor output main shaft, and reduction gearbox output shaft links to each other with eccentric shaft by shaft joint.
The present invention compared with prior art has following advantage and effect: adopt such scheme, can will be passed to oil cylinder, two outer tamping pickaxes under two interior tamping pickaxes, two levels from the exciting force of eccentric shaft successively by two horizontal upper cylinders, finish the vibration of inside and outside tamping pickaxe; By the holding action of tamping pickaxe, two outer tamping pickaxes in the oil cylinder Synchronization Control under two levels two, come railway ballast is rearranged closely knit simultaneously.Because the reaction force of tamping pickaxes, two outer pick arms generations is that hinge by the hinged place is delivered on the frame in two, no longer apply bigger reaction force to eccentric shaft and bearing, symmetrically arranged two horizontal upper cylinders are cancelled out each other to the horizontal component of making a concerted effort of eccentric shaft in addition, only produce vertical component seldom, therefore, can greatly improve the stressing conditions of eccentric shaft and bearing, reduce the high strength requirement of eccentric shaft and bearing, and then can reduce input power, improve the operating efficiency of tamping unit, prolong its application life, reduce production costs.
