Description

Vibration tamping device for hydraulic tamping vehicle

The utility model relates to a kind of railway track ballast tamping machine tool.

Development along with the China Railway cause, the method of making firm by ramming of China's railway track ballast aggregate and machinery is development constantly also, make firm by ramming from artificial pick in the early days of foundation, developing into artificial hand-held electric pick makes firm by ramming, these two kinds of major defects of manually making firm by ramming are that working strength of workers is big, inefficiency, in order to alleviate working strength of workers, increase work efficiency, and then adopt mechanical electric pick to make firm by ramming, electric pick is contained in 8 on the frame, by mechanical transmission mechanism the circuit ballast aggregate is made firm by ramming, adopt light hydraulic tamping machine that the circuit ballast aggregate is made firm by ramming to the end of the seventies, light hydraulic tamping machine is the concrete vibrating mechanism that utilizes hydraulic mechanism to promote and insert down, and vibrates the pick plate by eccentric wheel indirectly by the frame that shakes, its shortcoming is owing to adopt moving, static load cooperates indirectly, loss power is big, the direction of vibration confusion, with the folder solid yardage to inconsistent, influence tamping quality, can not adapt to the quality requirement of modernized circuit.

The purpose of this utility model provides a kind of high efficiency, loss power is little, the tamping equipment of the measured hydraulic pressure tamping car of matter that vibrates.

The frame part of making firm by ramming of tamping unit described in the utility model is installed in vehicle frame, and this tamping unit comprises: by interior pick, and the transmission that internal vibration pick plate and interior consolidated oil jar constitute; Outer pick, vibrate the transmission that pick plate and outer consolidated oil jar constitute outward, the cylinder seat of the cylinder seat of outer consolidated oil jar and reverse interior consolidated oil jar fuses with bearing pin, eccentric bushing on the interior consolidated oil jar cylinder seat is contained on the eccentric diameter of axle of eccentric main axis, and the structure of the inside and outside consolidated oil jar of opposite side is identical; Eccentric main axis is sleeved on the crane part, and hoist cylinder is connected on the crane part by ball pivot, and the middle part of hoist cylinder is connected on the tamping support part with hinge.When motor starts, vibrating motor, motor pulley drive the eccentric shaft belt pulley by belt, eccentric shaft is rotated, by vibration pick plate inside and outside the inside and outside consolidated oil jar drive both sides, make inside and outside pick vibration, the real action of the folder of inside and outside pick provides power by hydraulic power unit, control inside and outside consolidated oil jar by actuating element, drive inside and outside vibration pick plate, make inside and outside pick in vibration, finish and open and the real operation of folder, the ballast aggregate under the sleeper is closely knit, and can finish lifting and insert action down together with crane, inside and outside pick by actuating element operate lifting oil cylinder.

Nearly 32 of the tamping pickaxes that this device is installed, can improve the operating efficiency of making firm by ramming greatly, this device adopts the direct mating reaction of dynamic and static load, asynchronous concrete vibrating mode, under the situation that ballast aggregate amount one side is many, a side is few of the pick clamping that vibrates, when tamping pickaxe displacement is unequal, the side tamping pickaxe displacement that ballast is few is just long, and move in advance, thereby reach and corresponding identical extruding force, a pair of then tamping pickaxe continues evenly to move, the extruding ballast aggregate, it is closely knit that ballast aggregate is easy to, and porosity is low, improves tamping quality.Because this device is directly to vibrate the pick plate, vibration force and folder strength act directly on the ballast aggregate by vibration pick plate, can reduce power attenuation greatly.
